The cleaning assembly 2 is used as a self-cleaning object when the cleaning device works in a self-cleaning mode; when the cleaning device works in an external cleaning mode, the cleaning device is used as a cleaning execution body. If "external cleaning mode" is understood to mean: the mode of cleaning the floor, table top, wall or window etc. outside the cleaning device, then the "self-cleaning mode" is the mode of cleaning the internal components of the cleaning device itself. For example, the cleaning components may include, but are not limited to: rags, roll brushes, recycling pipes, recycling drums, etc. The working components may include, but are not limited to: a rolling brush driving device, a main motor generating suction force, a transfusion device outputting cleaning liquid, and the like.

The control device is connected with the working assembly and is used for controlling at least components in the working assembly to work so as to enable the cleaning equipment to work in a self-cleaning mode or an outward cleaning mode.

A cleaning device of the construction shown in fig. 1a, comprising: a floor brush 3 and a machine body. The floor brush 3 is arranged on the machine body. The body may be provided with, but not limited to: a clear water barrel 6, a recovery barrel 21, a recovery pipeline 22 and the like. One end of the recovery pipeline 22 is communicated with the suction nozzle 4 on the floor brush 3, and the other end is communicated with the recovery barrel 21. The floor brush 3 is provided with a suction nozzle 4, the suction nozzle 4 can suck dirt or dirty liquid on a surface to be cleaned (such as a floor, a table top, a carpet and the like), and the dirt or the dirty liquid enters a recovery barrel 21 through a recovery pipeline 22. The rolling brush 23 on the floor brush 3 is rotatable to clean the surface to be cleaned. Thus, in the embodiment of the cleaning device shown in FIG. 1a, the cleaning assembly may comprise: a rolling brush 23, a recovery duct 22, a recovery tank 21, and the like.

Specifically, when the cleaning device is in a self-cleaning mode, cleaning liquid is output to form accumulated liquid; and generating a dynamically-changed suction force, so that the accumulated liquid flows under the action of the dynamically-changed suction force to wash the self-cleaning object on the cleaning equipment.

Further, when the cleaning device works in the self-cleaning mode, the control device of the cleaning device controls the liquid conveying device to output the cleaning liquid to form accumulated liquid, and controls the main motor to generate the dynamically-changed suction force, so that the accumulated liquid flows under the action of the dynamically-changed suction force, and the self-cleaning object on the cleaning device is cleaned.

The details of how the main motor is controlled to generate a dynamically varying suction force will be described in detail below, and reference will be made to the corresponding contents below.

Further, the cleaning device provided by the embodiment may further include a preparation device. Not shown in fig. 1a, the preparation device is used for preparing a sterilization liquid. The prepared sterilization liquid can be contained in the clear water barrel 6. For example, the preparation apparatus may be an electrolyte preparation apparatus.

The power supply circuit is electrically connected with the control device and is used for being switched on or switched off under the control of the control device; and the electrolysis electrode is electrically connected with the power supply circuit, arranged in the clean water tank of the cleaning equipment and used for electrolyzing the liquid in the clean water bucket to generate a bacteria-removing liquid when the power supply circuit is switched on.

For example, when an electrolysis electrode having a constant voltage is put into tap water, since the tap water contains a constant chlorine element, a certain amount of hypochlorous acid is generated by the electrolysis electrode. In one embodiment, a certain amount of sterilization fluid is generated by electrolyzing cleaning fluid, which is usually tap water or clean water containing certain salt, with an electrolysis electrode disposed in a clean water tank containing the cleaning fluid. The process of preparing the sterilizing liquid in the self-cleaning method can be prepared before the self-cleaning process of the cleaning equipment is started, and the sterilizing liquid can be prepared all the time in the whole self-cleaning process or prepared in some self-cleaning steps of the cleaning equipment.

Also, referring to fig. 1a, the roll brush 23 is accommodated in the roll brush chamber. The rolling brush is stained with sewage and impurities when cleaning the surface to be cleaned, and due to the rotation of the rolling brush, there may be a spot of sewage or small impurities splashed onto the wall of the rolling brush chamber. Cleaning device is under the automatically cleaning mode, and the cleaning solution of formation hydrops of output can have certain degree of depth, and the volume is big promptly, and a large amount of hydrops can produce comparatively violent fluid flow effect under dynamic change's suction effect like this, when wasing round brush, recovery channel, the chamber wall in round brush chamber is in the same direction as the area also can be washed.

In addition, the sterilization liquid prepared by the preparation device in the embodiment can be used for self-cleaning of cleaning equipment, and can also be only used on self-cleaning objects (such as a roller brush and a recovery channel) after self-cleaning is finished, namely, clean water in a clean water barrel is used for cleaning in the self-cleaning process, and the sterilization liquid is sprayed on the self-cleaning objects for disinfection after the self-cleaning objects are cleaned.

In particular, the fluid delivery device may be used to deliver a cleaning fluid (e.g., clean water, a sterilant), such as by delivering the cleaning fluid delivery device to a self-cleaning object. The cleaning liquid output by the infusion device may be clear water, cleaning liquid mixed with a degerming agent, or degerming liquid obtained by electrolysis, and the like, which is not limited in this embodiment. Wherein the amount of formed liquid accumulation can be controlled by the control device. Typically, the cleaning device is placed on a base while it is self-cleaning. The base is matched with the positive cleaning equipment for use, can be used when the cleaning equipment is self-cleaned, and also has the functions of charging the cleaning equipment and the like. Assuming that the self-cleaning object includes a roller brush, the accumulated liquid may be partially absorbed by the roller brush, and a part of the accumulated liquid may remain on a base which is matched with the cleaning device, even in a cavity of the roller brush.

Further, the control device can control the main motor to work to generate a dynamically-changed suction force, so that the accumulated liquid flows under the action of the dynamically-changed suction force to clean the self-cleaning object. Specifically, the working power of the main motor can be adjusted through the control device to change the suction force, and the effect of continuously flushing the recovery pipeline by water flow can be simulated.

Fig. 1b shows a schematic structural diagram of a cleaning system provided in another embodiment of the present application. As shown in fig. 1b, the cleaning system comprises: cleaning apparatus 1, preparation device (not shown in the figures) and base 7. Cleaning device 1 can place in on base 7, the preparation facilities is used for preparing the degerming liquid. Wherein the cleaning apparatus comprises: cleaning component, work subassembly and controlling means. The cleaning assembly is used as a self-cleaning object when the cleaning device works in a self-cleaning mode; when the cleaning device works in an external cleaning mode, the cleaning device is used as a cleaning execution body. And the working assembly is used as a self-cleaning working load to clean the self-cleaning object when the cleaning equipment works in a self-cleaning mode, and is used as an external cleaning working load together with the cleaning execution body to clean a surface to be cleaned when the cleaning equipment works in an external cleaning mode. And the control device is used for controlling the work assembly to work, the work assembly comprises an infusion device, and the infusion device is used for outputting a sterilization liquid to form accumulated liquid under the control of the control device, so that the cleaning equipment can utilize the accumulated liquid to complete a self-cleaning task.

Further, the preparation device may be disposed on the cleaning apparatus, or on the base.

Specifically, the preparation apparatus includes: a power supply circuit and an electrolysis stage. The power supply circuit is electrically connected with the control device and is used for being switched on or switched off under the control of the control device. The electrolysis electrode is electrically connected with the power supply circuit, is arranged in the clean water barrel 6 of the cleaning equipment 1 or the water tank 72 on the base 7 and is used for carrying set voltage when the power supply circuit is conducted so as to electrolyze liquid in the clean water barrel and generate a bacteria removing liquid.

In specific implementation, after the cleaning device 1 is placed on the base 7, the cleaning device 1 can be in communication connection with the base in a wired or wireless manner, so that a control device on the cleaning device can send a control instruction to a power supply circuit arranged on the base 7.

Further, a liquid accumulation area 71 is arranged on the base 7, and a sterilization liquid can be accumulated in the liquid accumulation area 71 to soak and clean the self-cleaning object.

The self-cleaning method of the cleaning device will be explained in the following by means of a method embodiment.

Fig. 2 is a first flowchart of a self-cleaning method according to an embodiment of the present application, and referring to fig. 2, the self-cleaning method of a cleaning apparatus according to an embodiment of the present application is applied to a control device of the cleaning apparatus, and the cleaning apparatus further includes: the infusion set, the main motor and at least one self-cleaning object. The self-cleaning method comprises the following steps:

and S101, controlling the infusion device to work so as to output the cleaning liquid.

And S102, controlling the main motor to work to generate a dynamically changed suction force, so that the cleaning liquid flows under the action of the dynamically changed suction force to clean the self-cleaning object on the cleaning device.

In step S101, the cleaning liquid may be, but is not limited to: clean water, aqueous solution with cleaning agent or bacteria-removing liquid generated by electrolysis or other methods. The output of the cleaning liquid can be output by a pump on the cleaning device or by opening a valve on the liquid conveying pipeline of the cleaning device.

In the step S102, the liquid pumped by the main motor may be cleaning liquid output by the infusion device; or the cleaning liquid is output to the rolling brush by the infusion device and then overflows from the rolling brush to the cleaning liquid on the base; or after the rolling brush is wetted by the infusion device, the cleaning liquid accumulated on the liquid accumulation area after being scraped from the rolling brush is cleaned by the rolling brush. The liquid accumulation area can be positioned on a self-cleaning base matched with the self-cleaning equipment or in a cavity of the self-cleaning equipment. The actuating body generating the dynamically varying suction force may be the main motor on the cleaning device. The main motor is capable of generating a suction force when in operation. The main motor may have at least two powers, such as low power, high power, etc., and the varying amount of suction is generated by varying the switching of the main motor between the at least two powers. Alternatively, the gap suction force is generated by controlling the main motor to start and stop intermittently. Alternatively, the fan in the main motor is controlled to switch between forward rotation and reverse rotation to generate varying forces of suction and blowback.

For example, in the implementation, the main motor is controlled to operate at low power for a second, then operate at high power for B seconds, then switch to operate at low power for a second, and operate at high power for B seconds, and so on until a set time length is reached or a set cycle number is met. Wherein a may be greater than, equal to, or less than B, which is not limited in this embodiment. Similarly, for the scheme of intermittent starting and stopping of the main motor, the main motor can be controlled to operate for C seconds and stop for D seconds; and running for C seconds again, and then straightening for D seconds, and repeating the steps until the set time length is reached or the set cycle number is met, and the like. C may be greater than, equal to, or less than D, which is not limited in this embodiment. And for the positive and negative rotation scheme, the fan in the main motor can be controlled to rotate forwards for E seconds, then rotate reversely for F seconds, then rotate forwards for E seconds, rotate reversely for F seconds, and the like until the set time length is reached or the set cycle number is met. Similarly, E may be greater than, equal to, or less than F, which is not limited in this embodiment.

The main motor is controlled to work in such a way to generate dynamic suction force, under the action of the dynamic suction force, the accumulated liquid area reaches the recovery pipeline, and the cleaning liquid in the recovery pipeline can simulate the effect of continuous scouring of the effluent, so that the self-cleaning effect can be effectively improved.

For example, the fan of the main motor is used for generating dynamic suction force in a positive and negative rotation scheme, namely, the back blowing force is also generated between the suction forces. For example, the time of producing suction just makes the cleaning solution flow to the entrance of recycling bin or be close the entrance and do not get into the recycling bin from cleaning device's suction nozzle department, then under the effect of the blowing power of falling, the cleaning solution is backward again flows to the suction nozzle from the position of recycling bin entrance or being close the entrance, and is reciprocal so, and the cleaning solution makes a round trip to erode in the recovery pipeline, has washd the recovery pipeline, and this kind of washing power that makes a round trip also can use the round brush of suction nozzle department simultaneously, has also washd the round brush. When the cleaning liquid is more, the cleaning liquid stirred up by the rotating rolling brush can also clean the cavity wall of the rolling brush cavity.

In addition, in an embodiment provided by the present application, when the cleaning device performs step S102, step S101 may be performed simultaneously, or step S102 may be performed after step S101 is finished for a while. This application embodiment makes the cleaning solution wash the automatically cleaning object under dynamic change's suction effect through optimizing cleaning device's clean flow, has effectively improved cleaning device's automatically cleaning effect.

Self-cleaning objects in embodiments of the present application may include, but are not limited to: a rolling brush, a cleaning cloth, a recovery pipeline on the cleaning equipment, a recovery barrel and the like. In an implementation solution, a rotary output device, such as a motor + a rotary output component (e.g., similar to a pulsator structure in a washing machine), may be disposed in the recycling bin. The rotary output component is arranged in the recycling bin. When the cleaning equipment works in the self-cleaning mode, the control device of the cleaning equipment can send a control command to the motor, and the motor drives the rotary output component in the recovery barrel to rotate after receiving the control command so as to stir the sewage in the recovery barrel to flow at a high speed and clean the barrel wall of the recovery barrel.

In one embodiment provided herein, the self-cleaning object comprises a roller brush, and controlling the operation of the infusion device to deliver the cleaning liquid comprises the following steps, referring to fig. 3:

s103, a rolling brush infiltration stage: and controlling the infusion device to output cleaning liquid to the rolling brush so as to soak the rolling brush.

S104, stopping the liquid and rotating the rolling brush: and controlling the infusion device to stop working, and controlling the driving device to work to drive the rolling brush to rotate, so that the scraping device on the cleaning equipment can scrape off attachments and liquid on the rolling brush to form liquid accumulation in the liquid accumulation area.

For the above steps, when a circulation requirement exists, the roller brush wetting stage and the liquid stopping roller brush rotating stage are circulated according to the circulation requirement, and the step S103 and the step S104 are circularly completed. The cycling requirement may be configured in advance, such as cycling once, twice or more, and the like, and this embodiment is not limited in this respect. In order to clean the roller brush more cleanly and thoroughly, the cleaning device can repeat the steps S103 and S104 for multiple times in a circulating manner, and the amount of accumulated liquid is increased along with the increase of the repetition times, so that other self-cleaning objects can be cleaned more conveniently. The repeated steps not only can accumulate more accumulated liquid, but also can reduce the dirty concentration of the accumulated liquid, thereby being beneficial to cleaning other self-cleaning objects by the accumulated liquid.

In the step S103, the cleaning solution can be absorbed by the rolling brush, and the rolling brush can retain part of the cleaning solution after absorbing the cleaning solution, and the rolling brush is soaked in the cleaning solution, so that the attachments on the rolling brush can be wetted in the process of wetting the rolling brush, and the cleaning effect on the attachments on the rolling brush is improved.

Further, in step S104, after sufficient cleaning liquid is accumulated on the roller brush, the cleaning device stops outputting the cleaning liquid to the roller brush, the roller brush is driven by the roller brush motor to rotate, and then the scraping device acting on the surface of the roller brush can scrape most of the cleaning liquid accumulated on the roller brush. In the process of scraping the cleaning liquid, dirt on the rolling brush is also scraped clean along with the cleaning liquid, and the scraped attachment (dirt) and the liquid are accommodated in the accumulated liquid area to enter the accumulated liquid. In particular, the effusion region may be an area, such as a groove, on the base of the cleaning device. In one embodiment provided by the application, besides the scraping by the scraping device, the attachments and the cleaning liquid on the rolling brush can also be combined with the centrifugal force action of the rotation of the rolling brush, so that the attachments and the cleaning liquid can be separated from the rolling brush more quickly, and the rolling brush can be cleaned more cleanly.

In one embodiment provided herein, the self-cleaning object may further comprise a recycling pipe, and referring to fig. 4, the self-cleaning method of the cleaning apparatus further comprises the steps of:

s105, controlling the main motor to generate continuous suction force to suck the cleaning liquid, so that the flowing cleaning liquid flushes the recovery pipeline flowing through the recovery pipeline into the recovery barrel of the cleaning device.

S106, controlling the output quantity of the cleaning liquid of the infusion device, and triggering and controlling the main motor to work to generate a dynamically-changed suction force, so that the cleaning liquid flows under the action of the dynamically-changed suction force to clean the recovery pipeline.

In step S105, after the main motor generates the suction force, the cleaning liquid flows into the recycling bin of the cleaning device along the recycling pipeline under the action of the suction force. Specifically, the recycling bin is a container on the cleaning apparatus that stores the waste water generated after cleaning. When the cleaning apparatus is a hand-held floor washing machine, the recovery bucket is mounted on the cleaning apparatus. And when the cleaning device is an intelligent floor washing system with a base station, the recycling bin can be a recycling bin installed on the base station. In addition, the recovery pipeline is communicated between the suction port of the cleaning equipment and the recovery barrel.

In one embodiment provided herein, the continuous suction force is generated to suck the cleaning liquid such that the flowing cleaning liquid flushes the recovery pipe therethrough into the recovery tank of the cleaning device may be an intermittent process or a continuous process. For example, after enough cleaning liquid is accumulated on the self-cleaning base, the main motor provides the maximum suction force to continuously suck the cleaning liquid into the recycling bin through the recycling pipeline, and in the process of sucking the cleaning liquid into the recycling bin, a large amount of cleaning liquid flows into the recycling bin at a high speed, so that a large scouring force can be generated to scour dirt in the recycling pipeline. Alternatively, the main motor may be intermittently operated, for example, after the cleaning liquid area accumulates a sufficient amount of cleaning liquid, the main motor provides a suction force to suck a part of the cleaning liquid into the recovery tank through the recovery pipe, and then stops operating for a certain period of time, and after the cleaning liquid area accumulates a sufficient amount of cleaning liquid again, the main motor provides a suction force again to suck the cleaning liquid into the recovery tank through the recovery pipe.

In step S106, the reduction of the output of the cleaning solution can be controlled by controlling the fluid infusion device, such as the power of the pump, the operation mode or the operation duration of the pump. Alternatively, when the infusion device is a valve on an infusion line, the output can be controlled by controlling the opening of the valve. In this case, the reduction of the output of the cleaning liquid prevents the liquid accumulation region (a self-cleaning device or a cleaning liquid receiving region on a self-cleaning base) from accumulating too much water and overflowing the liquid accumulation region. The cleaning liquid produces mobile in-process under dynamic change's suction power effect, and wherein only a small part of cleaning liquid is sucked into the sewage case, and most cleaning liquid all is in recovery pipeline and hydrops district, if do not reduce the output quantity of cleaning liquid this moment, along with the extension of washing time, the accumulation volume of the cleaning liquid in hydrops district can be more and more to spill over hydrops district very easily. In addition, a large amount of cleaning liquid is pumped into the recycling bin in step S105, and in order to generate the effect of simulating continuous washing of water flow in step S106, the main motor is controlled to generate dynamic pumping force, and if the output amount of the cleaning liquid is large, the flowing cleaning liquid is easy to splash, so that the surrounding environment is polluted. In one embodiment provided by the present application, the recycling duct is cleaned by flowing cleaning liquid, and the cleaning roller or the cleaning cloth can be cleaned by flowing cleaning liquid indirectly. Since the cleaning liquid is initially accumulated in the liquid accumulation area, after the cleaning liquid in the liquid accumulation area is pumped into the recovery pipeline, the cleaning liquid can flow back to the liquid accumulation area in the back-and-forth cleaning process, and the rolling brush or the cleaning cloth can be cleaned by the cleaning liquid flowing back in the process.

In the examples provided herein, generating a dynamically varying suction force includes a variety of specific implementations. Wherein the main motor can be caused to generate different suction forces by controlling the power of the main motor to switch between at least two different powers. For example, when the cleaning liquid is required to flow from the lower part of the recovery pipeline to the upper part of the recovery pipeline, the power of the main motor can be maximized and the maximum suction force can be generated, wherein the suction force of the main motor to the cleaning liquid is larger than the gravity force of the cleaning liquid. When it is desired to cause the cleaning liquid to flow from above the recovery duct to below the recovery duct, the power of the main motor can be reduced so that the suction force generated thereby cannot overcome the gravity of the cleaning liquid itself, and the cleaning liquid can flow from above the recovery duct to below the recovery duct. The cleaning fluid can then be washed back and forth in the recovery pipe by cyclically varying the power level of the main motor. Also for cleaning the roll or wipe, the cleaning liquid is first pumped up to the uppermost part of the recovery duct and then is circulated back and forth in such a way that it is flushed down the recovery duct and against the roll or wipe, which effectively cleans the roll or wipe.

In addition, in one embodiment provided by the application, the intermittent suction force can be generated by controlling the main motor to be intermittently started and stopped, so that the dynamically-changed suction force can be generated. Alternatively, the fan in the main motor is controlled to switch between the forward rotation and the reverse rotation to generate the force varying the suction and the reverse blowing, thereby dynamically varying the suction force. Besides, there is also a feasible scheme that the suction force of the main motor is controlled by a valve to generate dynamic change, for example, an electric control valve is installed at one end of the suction port of the main motor, and the air volume sucked by the main motor can be controlled by controlling the size of the opening of the valve, so that the suction force of the main motor can be effectively controlled, and the suction force can generate dynamic change.

In an embodiment provided by the present application, the cleaning apparatus further includes a sterilization liquid preparation device, and the self-cleaning method further includes:

and controlling the work of the bacteria-removing liquid preparation device to prepare a bacteria-removing liquid, and taking the bacteria-removing liquid as a cleaning liquid or spraying the bacteria-removing liquid to the self-cleaning object after the self-cleaning object is finished.

The process of preparing the bacteria-removing liquid can be realized by putting an electrode with a certain voltage into tap water, and a certain amount of hypochlorous acid can be generated under the action of the electrode because the tap water contains a certain chlorine element. In a specific embodiment, a certain amount of sterilization liquid is generated by electrolyzing the cleaning liquid, usually by providing an electrolysis electrode in a tank containing the cleaning liquid (usually tap water or clean water containing a certain amount of salt). The process of preparing the sterilizing liquid in the self-cleaning method can be prepared before the self-cleaning process of the cleaning equipment is started, and the sterilizing liquid can be prepared all the time in the whole self-cleaning process or prepared in some self-cleaning steps of the cleaning equipment.

Further, referring to fig. 5, the self-cleaning method provided in the embodiment of the present application further includes the following steps:

s107, after the self-cleaning object is cleaned, controlling the infusion device to stop outputting the cleaning liquid.

S108, controlling the cleaning device to generate a drying air flow so as to dry the self-cleaning object.

S109, controlling the infusion device to spray the sterilization liquid to the self-cleaning object.

In step S107, when the liquid feeding device on the cleaning apparatus stops outputting the cleaning liquid, the preparation of the sterilizing liquid in the cleaning apparatus may be stopped or continued. After the self-cleaning equipment is cleaned, the subsequent maintenance of the self-cleaning object is convenient. The cleaning device will generate a drying air flow for drying the cleaning object. In particular, different drying methods are available for different self-cleaning objects, for example for a roller brush, the self-cleaning objects can be dried by the rotationally disturbed air flow of the roller brush and the suction air flow generated by the main motor together. It is possible for the recovery duct to be dried by means of a suction air flow generated by the main motor.

Further, in order to keep the self-cleaning object in a clean and sterile environment for a long time, in step S109, a sterilization liquid is sprayed to the self-cleaning device and the sterilization liquid is left on the self-cleaning device for a certain time, so as to achieve a purpose of bacteriostasis. In addition, specifically, in order to achieve better sterilization effect and sterilization time, the sterilized solution sprayed at this time has a higher concentration, which can increase the concentration of the sterilized solution by lengthening the preparation time of the sterilized solution. Or a certain medicament with a sterilization function is added into the sterilization liquid by a user, so that the concentration of the sterilization liquid is increased.

In one embodiment provided herein, the self-cleaning method further comprises the steps of:

s110, detecting the cleanliness of the self-cleaning object, and determining that the cleaning of the self-cleaning object is finished if the cleanliness meets a set requirement. Or

S110', when the cleaning time reaches the preset self-cleaning time, the self-cleaning object is determined to be cleaned.

Specifically, a detection piece can be arranged on a self-cleaning object of the cleaning equipment, and the detection piece can accurately detect the cleanliness of the self-cleaning piece. For example, at least one detection piece is respectively arranged on the rolling brush, the rolling brush cavity, the recovery pipeline and the recovery barrel.

In addition, step S110 can optimize the flow of the cleaning device self-cleaning process. For example, in the process of executing the above steps, such as steps S101 to S106, step S110 may be executed, i.e. the cleanliness of the self-cleaning object may be detected at any time during the self-cleaning process. And when the detection piece detects that the cleanliness of the self-cleaning object meets the set requirement, the self-cleaning object is cleaned, and the next step is carried out. Thus, the self-cleaning duration can be shortened, the self-cleaning process of the self-cleaning piece is more efficient, and unnecessary waste can be reduced.

Or, in step S110', if the self-cleaning duration reaches the preset self-cleaning duration, it is determined that the cleaning of the self-cleaning object is completed. At this time, there are two cases, one is that the cleaning meets the requirement of cleanliness, and the other is not. This scheme is long through setting up this predetermined automatically cleaning, is to avoid leading to cleaning device to be in the condition of automatically cleaning mode all the time because of some comparatively stubborn stains.

Further, referring to fig. 6, in an embodiment provided herein, the self-cleaning method further includes the following steps:

s111, monitoring the degree of contamination of the self-cleaning object when the cleaning duration reaches the first duration.

And S112, if the dirt degree is larger than a first preset value, adjusting at least one of the output quantity of the cleaning liquid, the dynamic change strategy of the suction force, the time length corresponding to the rolling brush infiltration stage and the time length corresponding to the liquid stopping rolling brush rotation stage.

Wherein the first duration is less than a preset self-cleaning duration. In steps S111 and S112, by detecting the degree of contamination of the self-cleaning object and adjusting at least one of the output amount of the cleaning liquid, the dynamic change strategy of the suction force, the duration corresponding to the rolling brush soaking stage and the duration corresponding to the liquid stopping rolling brush rotating stage according to the actual situation, the cleaning efficiency of the self-cleaning object can be effectively improved, and the cleaning time of the self-cleaning object and the resources consumed during cleaning can be reduced. Specifically, in the process of executing steps S101 to S106, the cleaning apparatus may execute steps S111 and S112 before or simultaneously, and appropriately adjust the amount of the cleaning liquid delivered to the roller brush by the fluid delivery device, the dynamic variation strategy of the suction force, the time length corresponding to the wetting phase of the roller brush, the time length corresponding to the rotation phase of the liquid-stopping roller brush, and the like according to the degree of contamination of the roller brush.

Further, referring to fig. 7, in an embodiment provided herein, the self-cleaning method further includes the following steps:

s113, detecting the dirt degree of the self-cleaning object.

S114, acquiring the time length from the last self-cleaning of the self-cleaning object to the current moment.

S115, self-cleaning parameters are determined according to at least one of the degree of contamination and the duration.

Here, steps S113 to S115 may be operations before S101 in this embodiment. In step S115, the self-cleaning parameters include: at least one of the preparation amount of the sterilization liquid, the output amount of the sterilization liquid, the self-cleaning duration and the suction force dynamic change strategy. Specifically, for example, in the process of preparing the sterilization liquid, the preparation amount of the sterilization liquid can be determined according to the degree of contamination of the self-cleaning object and the time length from the last self-cleaning of the self-cleaning object to the current moment, so that the self-cleaning object can have enough sterilization liquid in the self-cleaning process, and the prepared sterilization liquid can be used in time to reduce unnecessary waste. For another example, in step S103, the amount of the cleaning liquid containing the bactericide that is output to the roll brush by the liquid feeding device may be determined according to at least one of the degree of contamination and the length of time of the roll brush, so that it is possible to complete the cleaning of the roll brush using the minimum amount of the cleaning liquid. In step S104, the rotation speed of the rolling brush may be determined according to at least one of the degree of contamination and the duration of the rolling brush, so as to save the electric power of the self-cleaning device and prolong the endurance of the self-cleaning device. In addition, in step S106, when the main motor of the cleaning apparatus outputs the dynamically changing suction force to clean the recovery pipeline, the strategy of the dynamic change of the suction force may also be determined according to at least one of the degree of contamination and the duration of the rolling brush. When the dirt degree of the recovery pipeline is large, the suction force generated by the main motor can be controlled to adopt a strong dynamic change strategy, and when the dirt degree or the time length of the recovery pipeline is short, the suction force generated by the main motor can be controlled to adopt a common dynamic change strategy.

In an embodiment provided by the present application, referring to fig. 8, there is provided another self-cleaning method for a cleaning apparatus, adapted to a control device of the cleaning apparatus, the cleaning apparatus further comprising: infusion set, drive arrangement and round brush. The self-cleaning method comprises the following steps:

s201, a rolling brush infiltration stage: and controlling the infusion device to output cleaning liquid to the rolling brush so as to soak the rolling brush.

S202, a liquid stopping rolling brush rotation stage: and controlling the infusion device to stop working, and controlling the driving device to work to drive the rolling brush to rotate, so that attachments and liquid on the rolling brush can be scraped to a liquid accumulation area through a scraping device on the cleaning equipment.

For the above steps, when there is a circulation request, the circulation requests of the circulation roller brush wetting stage and the liquid stopping roller brush rotating stage, and the circulation completion steps S201 and S202 may be configured in advance, for example, one circulation, two or more circulations, and the embodiment is not limited in this embodiment. In order to clean the roller brush more cleanly and thoroughly, the cleaning device can repeat the steps S201 and S202 for multiple times, and as the number of times of repetition increases, the amount of cleaning liquid accumulated in the liquid accumulation area increases, so that the cleaning device is more beneficial to cleaning other self-cleaning objects. The repeated steps not only can accumulate more cleaning liquid, but also can reduce the dirt concentration of the cleaning liquid, thereby being beneficial to cleaning other self-cleaning objects by the cleaning liquid.

In the step S201, the rolling brush can absorb the cleaning solution, and the rolling brush can retain part of the cleaning solution after absorbing the cleaning solution, and the rolling brush is soaked in the cleaning solution, so that the attachments on the rolling brush can be wetted in the process of wetting the rolling brush, and the cleaning effect on the attachments on the rolling brush is improved.

Further, in step S202, after sufficient cleaning liquid is accumulated on the roller brush, the cleaning device stops outputting the cleaning liquid to the roller brush, the roller brush is driven by the roller brush motor to rotate, and then the scraping device acting on the surface of the roller brush can scrape most of the cleaning liquid accumulated on the roller brush. In the process of scraping the cleaning liquid, dirt on the rolling brush is also scraped clean along with the cleaning liquid, and the scraped attachments (dirt) and the liquid are contained in the liquid accumulation area. In particular, the effusion region may be a region, such as a groove or the like, on a self-cleaning foot of the cleaning device. In one embodiment provided by the application, besides the scraping by the scraping device, the attachments and the cleaning liquid on the rolling brush can also be combined with the centrifugal force action of the rotation of the rolling brush, so that the attachments and the cleaning liquid can be separated from the rolling brush more quickly, and the rolling brush can be cleaned more cleanly.

In one embodiment provided herein, referring to fig. 9, the self-cleaning method further includes:

s203, detecting the dirt degree of the rolling brush.

S204, acquiring the time length of the rolling brush from the last self-cleaning to the current moment.

S205, self-cleaning parameters are determined according to at least one of the dirt degree and the time length.

In this embodiment, steps S203 to S205 may be performed before S201. In step S205, the self-cleaning parameters include: at least one of the preparation amount of the sterilization liquid, the output amount of the sterilization liquid, the self-cleaning duration and the suction force dynamic change strategy. Specifically, for example, in the process of preparing the sterilization liquid, the preparation amount of the sterilization liquid can be determined according to the degree of contamination of the self-cleaning object and the time length from the last self-cleaning of the self-cleaning object to the current moment, so that the self-cleaning object can have enough sterilization liquid in the self-cleaning process, and the prepared sterilization liquid can be used in time to reduce unnecessary waste. For another example, the amount of the cleaning solution containing the bactericide that is delivered from the liquid delivery device to the roll brush may be determined based on at least one of the degree of contamination and the length of time of the roll brush, so that it is possible to complete the cleaning of the roll brush with the minimum amount of the cleaning solution. In step S202, the rotation speed of the rolling brush may also be determined according to at least one of the degree of contamination and the duration of the rolling brush, so as to save the electric power of the self-cleaning device and prolong the endurance of the self-cleaning device. In addition, when the main motor of the cleaning device outputs the suction force which changes dynamically to clean the recovery pipeline, the strategy of the dynamic change of the suction force can also be determined according to at least one of the degree of dirt and the time length of the rolling brush. When the dirt degree of the recovery pipeline is large, the suction force generated by the main motor can be controlled to adopt a strong dynamic change strategy, and when the dirt degree or the time length of the recovery pipeline is short, the suction force generated by the main motor can be controlled to adopt a common dynamic change strategy.

In one embodiment provided herein, the cleaning apparatus further comprises a main motor, a recycling bin and a recycling pipe, and referring to fig. 10, the self-cleaning method further comprises the steps of:

s206, controlling the liquid conveying device to output cleaning liquid, the main motor to work and controlling the driving device to work so as to drive the rolling brush to rotate, so that accumulated liquid in the accumulated liquid area is sucked into a recovery barrel, and the recovery pipeline is cleaned.

S207, controlling the output quantity of the cleaning liquid of the infusion device, and maintaining the working states of the main motor and the driving device so as to continuously clean the recovery pipeline.

In step S206, the driving device works and drives the rolling brush to rotate, so that the rolling brush continues to complete self-cleaning, the rolling brush generates accumulated liquid in the self-cleaning process, the accumulated liquid is accommodated in the accumulated liquid accommodating area, when the infusion device continuously outputs cleaning liquid, the amount of the accumulated liquid is increased, the accumulated liquid is pumped into the recycling bin under the action of the suction force generated by the main motor, and when the accumulated liquid flows to the recycling bin from the accumulated liquid area, the flowing accumulated liquid can flush the pipeline. In step 207, the utilization rate of the cleaning liquid can be improved by controlling the output amount of the cleaning liquid from the liquid feeding device, and specifically, the specific amount of the output of the cleaning liquid can be adjusted according to the degree of contamination of the rolling brush, which can be achieved by performing steps S203 to S205. In addition, through the output volume of adjustment cleaning solution, can also save the quantity of cleaning solution, for example after the round brush sanitization, also tentatively sanitization in the recovery pipeline, because the cleaning solution of wasing the recovery pipeline before is the sewage of scraping from the round brush, when washing the recovery pipeline, a certain amount can be remained to these sewage on the recovery pipeline, it does not need a lot of water yield to clear away these sewage this moment, so through the output volume of control cleaning solution, it is clean with the recovery pipeline washout through a small amount of cleaning solution.

Further, the self-cleaning method further comprises:

and controlling the main motor to generate a dynamically-changed suction force, so that the cleaning liquid flows under the action of the dynamically-changed suction force, and simulating water flow to clean the recovery pipeline.

In order to achieve a better flushing effect of the recovery line, the cleaning liquid is made to flow by means of a dynamic suction force and the recovery line is flushed. Specifically, when washing the recovery pipeline, at first main motor provides the biggest suction, with the cleaning solution suction to the end of recovery pipeline (the one end that is close to the recycling bin), then main motor reduces the suction size, and the cleaning solution can flow back to the bottom of recovery pipeline from the end of recovery pipeline again, through circulating many times, just can make the suction that main motor produced for dynamic change's process to enable the cleaning solution and make a round trip to wash the recovery pipeline.

The main body for executing the steps in the above embodiments is a cleaning device. The following embodiments provide a self-cleaning method of a cleaning apparatus, which implements a control device of a main body, specifically, a cleaning apparatus. In addition, the cleaning apparatus further includes: infusion set, main motor and self-cleaning object. The self-cleaning method of the cleaning device comprises the following steps:

s301, controlling the infusion device to work to output a sterilization liquid.

And S302, controlling the main motor to work to generate a dynamically changed suction force, so that the cleaning liquid flows under the action of the dynamically changed suction force to clean the self-cleaning object.

When the cleaning device is located on the self-cleaning base, the cleaning member (cleaning cloth or rolling brush) is wetted by the first cleaning liquid, and when the rolling brush is performing self-cleaning, the cleaning liquid on the rolling brush is scraped off to form accumulated liquid. Or the cleaning member is wetted by the output cleaning liquid after the cleaning member absorbs the maximum amount of water, and the excess water is accumulated in the cavity of the self-cleaning base or the accommodating cavity of the cleaning device. At this time, the cleaning liquid scraped off by the rolling brush and the cleaning liquid accumulated on the cleaning piece, in the cavity of the self-cleaning base or in the accommodating cavity of the cleaning equipment are equivalent to accumulated liquid. Then, the suction force of the main motor is changed to make the main motor dynamically change, the accumulated liquid can flow under the action of the dynamically changed suction force, the flowing direction is continuously changed along with the dynamically changed suction force, and the self-cleaning object can be cleaned in the flowing process.

Further, when the self-cleaning object includes a roll brush, the cleaning apparatus further includes a driving device. Correspondingly, the step S301 "of controlling the infusion device to operate to output a sterilization liquid" includes the following steps:

s303, a rolling brush infiltration stage: and controlling the infusion device to output the sterilization liquid to the rolling brush so as to infiltrate the rolling brush.

S304, a liquid stopping rolling brush rotation stage: the infusion device is controlled to stop working, and the driving device is controlled to work to drive the rolling brush to rotate, so that the scraping device on the cleaning equipment can scrape attachments and liquid on the rolling brush to form accumulated liquid in the accumulated liquid area.

In the above steps, when a circulation requirement exists, the rolling brush infiltration stage and the liquid stopping rolling brush rotation stage are circulated according to the circulation requirement.

Under a specific use condition, firstly, the cleaning equipment enters a self-cleaning mode, the control device controls the infusion device to work and convey sterilizing liquid to the rolling brush in response to a control signal of the self-cleaning mode, the rolling brush is wetted at the moment, and after the rolling brush is wetted, the control device controls the infusion device to stop working and controls the driving device to work to drive the rolling brush to rotate, so that attachments and liquid on the rolling brush are scraped to a liquid accumulation area to form liquid accumulation through a scraping device on the cleaning equipment. Then the control device controls the main motor to work to generate a dynamically changed suction force, so that the accumulated liquid flows under the action of the dynamically changed suction force to clean the self-cleaning object. Specifically, the accumulated liquid formed in the accumulated liquid area may be formed by scraping the sterilizing liquid on the rolling brush by the scraping device after the rolling brush is infiltrated, or may be formed by jointly forming the sterilizing liquid flowing out of the rolling brush and the sterilizing liquid on the rolling brush scraped by the scraping device when the rolling brush is infiltrated. When the accumulated liquid flows under the action of the dynamically changed suction force so as to clean the self-cleaning object, the self-cleaning object can be one object or a plurality of objects, for example, one object can be a recovery pipeline, and a plurality of objects can be rolling brushes and recovery pipelines.

Further, in one embodiment provided herein, the self-cleaning object further comprises a recovery duct. Correspondingly, the method provided by the embodiment may further include the following steps:

s305, controlling the main motor to generate continuous suction force to suck the accumulated liquid, so that the flowing accumulated liquid washes the flowing recovery pipeline to the recovery barrel of the cleaning equipment;

s306, controlling the liquid amount of the infusion device, and triggering the step of controlling the main motor to work to generate the dynamically changed suction force, so that the accumulated liquid flows under the action of the dynamically changed suction force, and the recovery pipeline is cleaned.

In the above steps, controlling the operation of the main motor to generate the dynamically varying suction force may be controlled by: 1. the main motor is controlled to switch between at least two powers to generate a suction force of varying magnitude. 2. And controlling the main motor to intermittently start and stop so as to generate intermittent suction force. 3. The fan in the main motor is controlled to switch between forward rotation and reverse rotation to produce varying forces of suction and blowback.

Further, the cleaning apparatus further includes: degerming liquid preparation facilities. The self-cleaning method of the cleaning equipment further comprises the step that the controller controls the work of the bacteria-removing liquid preparation device to prepare the bacteria-removing liquid. The sterilizing liquid preparing apparatus may prepare the sterilizing liquid in various ways, and in one embodiment, the sterilizing liquid may be generated by disposing an electrode in the cleaning liquid and then by electrolyzing the cleaning liquid. Or the bacteria removing liquid preparation agent is arranged in the bacteria removing liquid preparation device, and the bacteria removing liquid preparation agent is continuously released into the cleaning liquid through the bacteria removing liquid preparation device, so that the bacteria removing agent is prepared by the cleaning equipment.

Referring to fig. 11, in an embodiment provided herein, there is provided another self-cleaning method for a cleaning apparatus, which is applied to a control device of the cleaning apparatus, and the cleaning apparatus further includes: infusion set, drive arrangement and round brush. The self-cleaning method comprises the following steps:

s401, a rolling brush infiltration stage: and controlling the infusion device to output cleaning liquid to the rolling brush so as to soak the rolling brush.

S402, a liquid stopping rolling brush rotation stage: and controlling the infusion device to stop working, and controlling the driving device to work so as to drive the roller brush to rotate, so that attachments and liquid on the roller brush can be scraped to the accumulated liquid area through a scraping device on the cleaning equipment.

For the above steps, when there is a circulation requirement, the circulation requirements of the circulation rolling brush wetting stage and the liquid stopping rolling brush rotating stage, and the circulation completion steps S401 and S402 may be configured in advance, for example, the circulation is performed once, twice or more, and the like, which is not limited in this embodiment. In order to clean the roller brush more cleanly and thoroughly, the cleaning device can repeat the steps S401 and S402 for multiple times in a circulating manner, and the accumulated cleaning liquid in the liquid accumulating area is more and more increased along with the increase of the repetition times, so that other self-cleaning objects can be cleaned more favorably. The repeated steps not only can accumulate more cleaning liquid, but also can reduce the dirt concentration of the cleaning liquid, thereby being beneficial to cleaning other self-cleaning objects by the cleaning liquid.

Further, referring to fig. 12, in an embodiment provided herein, the cleaning apparatus further includes a main motor, a recycling bin, and a recycling duct, and the self-cleaning method further includes the steps of:

s403, cleaning the recovery pipeline stage: after the liquid stopping rolling brush rotates, the liquid conveying device is controlled to output cleaning liquid, the main motor works and the driving device works, so that accumulated liquid in the accumulated liquid area is sucked into the recycling bin.

S404, a rolling brush dehydration stage: and controlling the infusion device to stop working and the main motor and the driving device to continue working so as to dehydrate the roller brush.

In step S403, the fluid infusion device outputs a cleaning solution for wetting the roller brush or forming a liquid accumulation, wherein the liquid accumulation is a liquid contained in the liquid accumulation region. Thereby main motor work produces suction, and drive arrangement drive round brush rotates simultaneously to clean the round brush, the suction that main motor produced inhales the hydrops in the hydrops district to the recycling bin, and the hydrops is just cleaned the recovery tube by the in-process of being pumped to the recycling bin.

In step S404, the driving device drives the roller brush to rotate so as to dehydrate the roller brush, and the main motor is operated to generate a suction force to suck the accumulated liquid in the accumulated liquid area or the cleaning liquid scraped from the roller brush into the recycling bin.

Further, in an embodiment provided in the present application, the cleaning apparatus further includes a main motor, a recycling bin, and a recycling pipe, and the self-cleaning method further includes the steps of:

and (3) a rolling brush dehydration recovery stage: and after the liquid stopping roller brush rotation stage, controlling the main motor and the driving device to work so as to dehydrate the roller brush and recover accumulated liquid to a recovery barrel through a recovery pipeline.

Further, in an embodiment provided herein, before the rolling brush wetting stage, the self-cleaning method further includes the following steps:

a bacteria removing liquid preparation stage: and controlling the bacteria-removing liquid preparation device to work so as to generate bacteria-removing liquid.

Wherein the bacteria-free liquid preparation device keeps working in a stage after the bacteria-free liquid preparation stage. The device for preparing the bacteria-removing liquid can prepare the bacteria-removing liquid at a stable speed in the whole self-cleaning process of the cleaning equipment after the preparation stage of the bacteria-removing liquid, and can also prepare the bacteria-removing liquid at different speeds in different stages or processes. For example, the sterilization liquid preparation apparatus is operated at full power and at the maximum speed to prepare the sterilization liquid in the roller brush soaking stage, and is operated at normal power and at a medium speed to prepare the sterilization liquid in the cleaning and recycling pipe stage.

Further, in an embodiment provided herein, the self-cleaning method further includes the following steps:

s405, detecting the dirt degree of the rolling brush.

S406, self-cleaning parameters are determined according to the dirt degree.

Wherein the self-cleaning parameters comprise at least one of: the output quantity of the cleaning solution, the working duration of the infusion device, the rotating speed of the rolling brush, and the cycle times of the rolling brush infiltration stage and the liquid stopping rolling brush rotation stage. Specifically, for example, during the process of preparing the sterilizing liquid, the preparation amount of the sterilizing liquid can be determined according to the degree of contamination of the self-cleaning object and the time from the last self-cleaning of the self-cleaning object to the current moment, so that the self-cleaning object can have enough sterilizing liquid during the self-cleaning process, and the prepared sterilizing liquid can be used in time to reduce unnecessary waste. In one embodiment provided herein, the self-cleaning process is broadly divided into four phases: preparing a sterilization liquid, soaking by using a rolling brush, cleaning and recovering a pipeline, and dehydrating by using the rolling brush. The specific cleaning process can be referred to the following table.

In the above table, the rolling brush soaking includes two steps, which may be cycled back and forth several times until the rolling brush is cleaned. In addition, "the sterilization liquid preparation" in the table indicates that the sterilization liquid preparation apparatus prepares the sterilization liquid, which can be obtained by electrolyzing the cleaning liquid in one embodiment. Wherein the cleaning solution can be common clear water or clear water containing sodium chloride. In the preparation process of the sterilization liquid, whether the sterilization liquid preparation device is started or not is determined, and various technical schemes are provided in the embodiment provided by the application, wherein the first technical scheme is that after the cleaning equipment starts the self-cleaning process, the sterilization liquid preparation device starts to prepare the sterilization liquid, after the sterilization liquid reaches a certain amount, other self-cleaning steps are started, and in the subsequent self-cleaning steps, the sterilization preparation device is always started. The second technical scheme is that after the cleaning equipment starts the self-cleaning process, the bacteria-removing liquid preparation device starts to prepare the bacteria-removing liquid, the bacteria-removing liquid preparation device is closed after the bacteria-removing liquid reaches a certain amount, and then other self-cleaning steps are started. The third technical scheme is that the required amount of the sterilization liquid is determined by detecting the dirt degree of the rolling brush, and then whether the sterilization liquid preparation device is started or not is determined by combining the required amount of the sterilization liquid and the preset cleaning duration in the self-cleaning process. For example, in the self-cleaning process of the self-cleaning equipment, the required amount of the sterilization liquid is determined in advance by detecting the dirt degree of the rolling brush, so that the time for preparing the sterilization liquid is also determined, then the sterilization liquid preparation device is started in the sterilization liquid preparation stage and the rolling brush soaking stage, and the sterilization liquid preparation device is closed in the cleaning and recycling pipeline and the rolling brush dehydration stage.

After the self-cleaning process is started, firstly, preparing a sterilization liquid: the main motor in the cleaning equipment is closed, the rolling brush motor is closed, the infusion device is closed, the bacteria-removing liquid preparation device is opened, and the phase lasts for 30 seconds, so that the bacteria-removing liquid quantity meets the use requirement.

Then, the rolling brush soaking comprises two stages, namely a rolling brush soaking stage (A1) and a liquid stopping rolling brush rotating stage (A2). And in the infiltration stage of the rolling brush, a main motor in the cleaning equipment is closed, sewage cannot be sucked, the infusion device conveys the bacteria-removing liquid to the rolling brush, the rolling brush motor stops rotating, and at the moment, the bacteria-removing liquid preparation device is started. The rolling brush has certain water absorption, so that the sterilization liquid can be retained on the rolling brush and infiltrated by the rolling brush. In the liquid stopping rolling brush rotation stage, the main motor stops rotating, the rolling brush motor rotates and drives the rolling brush to rotate together, and the infusion device is closed, so that the cleaning liquid on the rolling brush is scraped completely.

Subsequently, the recovery pipe is cleaned: the main motor is turned on and the suction force of the main motor is in a dynamically changing state. So that the accumulated liquid can be cleaned back and forth on the recovery pipeline. The round brush motor is opened to make the hydrops on the round brush strike off totally, in addition, infusion set and degerming liquid preparation facilities are the state of opening also, and infusion set's output quantity and output time can detect the dirty degree of round brush according to the detection piece and adjust.

And finally, dewatering by a rolling brush: the main motor is started to completely suck the accumulated liquid, the rolling brush motor is started to completely remove the accumulated liquid on the rolling brush, the infusion device stops working, and the bacteria-removing liquid preparation device is still started to prepare sufficient bacteria-removing liquid.

The different self-cleaning modes of the cleaning device can include at least one of the following modes: cleaning time of the self-cleaning object, dehydration time of the self-cleaning object, flow rate of a liquid conveying device of the cleaning device, main motor power of the cleaning device, and rotation speed of a rolling brush of the cleaning device.

When the self-cleaning objects are the drum brush and the suction passage, cleaning times of the drum brush and/or the suction passage may be different for different self-cleaning modes, and dehydration times of the drum brush and/or the suction passage may be different.

In combination with the above, the self-cleaning process of the self-cleaning device, in another embodiment provided by the present application, the self-cleaning process of the self-cleaning device further comprises a sterilization maintenance phase at the end. The specific procedure can be seen in the following table.

In the above table, at the cleaning stage of the cleaning and recycling pipeline, the infusion device may be opened or closed, which may be set according to specific practical situations, when the contamination degree of the recycling pipeline is higher, the infusion device may be opened at this time to provide sufficient bacteria-removing liquid to clean the recycling pipeline, and when the contamination degree of the recycling pipeline is lower, the infusion device may be closed at this time to save the bacteria-removing liquid.

In the last sterilization maintenance stage, the main motor is closed, the rolling brush motor is closed, the infusion device is opened to convey sterilization liquid to the rolling brush, and the sterilization liquid preparation device is opened. The period only lasts for a short time, such as 3 seconds, 5 seconds and the like, so that the infusion device is effectively prevented from outputting more sterilization liquid, and accumulated liquid is generated on the self-cleaning base.

To sum up, the technical scheme that this application embodiment provided, through optimizing cleaning equipment's clean flow, output cleaning solution to form the hydrops, then produce dynamic change's suction force, make the hydrops produce under dynamic change's suction force effect and flow, in order right self-cleaning object on the cleaning equipment washs, thereby effectively improves cleaning equipment's automatically cleaning effect.

In order to facilitate understanding of the technical solution of the present application, specific application scenarios are given below to describe in detail the self-cleaning method of the cleaning device provided in the present application.

The application scene one:

after the cleaning equipment works for a period of time, a user thinks that the cleaning equipment is dirty, and the user manually triggers a self-cleaning control on the cleaning equipment according to the dirty degree of the cleaning equipment. And starting the cleaning equipment, preparing a sterilization liquid, and entering the next stage or preparing and using the sterilization liquid when the preparation amount of the sterilization liquid meets the requirement. After entering the next stage, the transfusion device outputs a sterilization liquid to infiltrate the rolling brush and form accumulated liquid at the rolling brush. And then, stopping outputting the degerming liquid, starting the roller brush motor, rotating the roller brush, and quickly scraping dirt on the roller brush by a scraping device on the roller brush. The two stages of outputting the bacteria removing liquid and stopping the rotation of the output rolling brush can be circulated for many times. After the circulation requirement is met, the main motor of the cleaning equipment is started, the rolling brush motor is started, the infusion device is started (bacteria removing liquid is output), a large amount of accumulated liquid is rapidly sucked into the recovery barrel, and the accumulated liquid rapidly passes through the recovery pipeline and can completely flush dirt in the recovery pipeline. And then, the output quantity of the bacteria removing liquid is reduced, the main motor maintains the current working state to suck the accumulated liquid, and the recovery pipeline is continuously flushed by small water quantity. Of course, the control device can also control the main motor to generate dynamically-changed suction force so as to simulate the effect of continuously flushing the cleaning pipeline by water flow.

Application scenario two

During the self-cleaning process of the cleaning equipment, continuously detecting the dirt degree in the cleaning equipment, when the self-cleaning is carried out for a period of time (first preset time), the detected dirt degree does not meet the requirement, indicating that the cleaning effect is not good, adjusting the relevant operation parameters of the self-cleaning by the cleaning equipment, and continuously self-cleaning the cleaning equipment according to the adjusted relevant operation parameters.

Application scenario three

Cleaning equipment constantly detects cleaning equipment's dirty degree at the in-process of treating clean surface and wasing, after dirty degree reaches preset grade, and when lasting the preset time, the self-cleaning mode of automatic start for cleaning equipment utilizes this self-cleaning mode to carry out the automatically cleaning operation to cleaning equipment.
