Detailed Description

The hair of the human and/or pet is not limited to be easily wound on the rolling brush during the operation of the cleaning device, and threads or filiform objects with the same or similar characteristics with the hair, such as thread ends, cotton velvet and the like also have the same winding effect on the rolling brush.

The cleaning device for cleaning the roller brush and the cleaning system provided with the cleaning device according to the embodiments of the present invention can clean the hair wound around the roller brush of the cleaning device, and can also clean the thread-like or thread-like objects such as the thread ends and the lint from the roller brush. That is, the embodiment of the present invention has the same or equivalent removing effect as hair on the thread-like or thread-like objects such as lint and lint wound around the roll brush.

For convenience of description, the following is described with the main scenario of removing hairs wound around the roller brush of the cleaning device. It will nevertheless be understood that no limitation of the scope of the embodiments of the utility model is thereby intended, as illustrated in the accompanying drawings.

In fact, users have become aware of this problem in situations where the winding of hair on a roller brush can have many adverse consequences. Thus, there are a number of different approaches in the prior art to clean hair that is entangled in the rolling brush of a cleaning device, including, in particular, manual cleaning, semi-automatic cleaning, and automatic cleaning.

Wherein, manual cleaning is that the hair on the round brush is cut and cleaned for the handheld cutter of user. However, this method requires manual intervention operation of the user, easily dirties the hands, and has a complicated operation process and poor user experience.

The semi-automatic cleaning is generally implemented by manually operating a cutting device arranged on a base station or a cleaning device to cut and clean hairs on the rolling brush. As mentioned above, the cleaning apparatus may be an apparatus that sucks dust as its main function or only function, such as a vacuum cleaner, a dust suction robot; or may be a device that sucks dust as one of its auxiliary functions or functions, such as a sweeping robot. The base station is a device for docking the cleaning apparatus, integrates the main functions of providing the cleaning apparatus with corresponding operations, and can provide the cleaning apparatus with hair removal assistance operations. The main functions of the base station differ depending on the type of cleaning device. In particular, when a vacuum cleaner is used, the base station primarily provides a charging function for the vacuum cleaner. When the base station is a dust collection robot or a floor sweeping robot, the base station mainly has the functions of charging, dirty mop recycling, new mop replacing and the like.

In some known embodiments, the cutting device may be provided on either the base station or the cleaning device. In use, the user operates the cutting device to move along the radial direction of the rolling brush from the outside to the inside so as to cut hair. However, hair is usually wound on the surface of the rolling brush, and the inside of the rolling brush has an available space, and the hair has certain strength. When cutting, the blade of the cutting device pushes the hair into the roller brush, and the purpose of cutting the hair cannot be achieved.

In fact, the semi-automatic cleaning uses a blade moving radially to Cut the hair, which is equivalent to performing a chopping action (Cut) on the hair. It is known from simple physical knowledge that both ends of hair are fixed to cut or cut the hair into filaments or threads having good flexibility. However, it will be appreciated by those skilled in the art that such filaments or threads of hair are typically wound or coiled around the roller brush by virtue of their relatively large length, and that the bristles and rubber strips on the roller brush are flexible and difficult to hold or support. This is why the semi-automatic cleaning uses the radially moving blade to cut the hair, which results in poor cleaning effect or even failure to cut the hair.

The automatic cleaning is generally that a cutting device arranged on a base station or a cleaning device automatically cuts and cleans the hair on the rolling brush. In some known embodiments, the cutting device is disposed on the base station and is driven by the driving structure to move along the axial direction of the rolling brush to cut and clean the hair. However, the rubber strips and the bristles arranged on the roller brush are generally arranged in a V shape. Furthermore, in some cases, in order to prevent the hair from being entangled, the bottom of the roller brush is generally provided with anti-entanglement ribs protruding from the surface of the roller brush. Thus, the blades of the cutting device are virtually incapable of performing uninterrupted linear movements. Otherwise, either the blade is broken or the rubber strip, bristles and anti-wind rib are cut together, under the blockage of the rubber strip, bristles and anti-wind rib. In addition, in the automatic cleaning method, the hair is Cut, and there is a problem that the hair is not fixed, and thus the cleaning effect is not good.

In other known embodiments of automatic cleaning, the cutting device employs two oppositely moving cutting blades. The cutting blades are staggered with respect to each other, so that a cutting action (Shears) can be formed on hairs entering the cutting opening. With respect to the above-described cutting (Cut) action, cutting does not require that the hair be fixed, as long as the hair enters the cutting edges of the two cutting blades, and can be Cut off as well, if not fixed. Therefore, the hair cleaning effect is better

However, the solution principle requires that the two cutting blades are made of a hard material such as metal and have sharp edges. It is obvious that the cutting blade of the known embodiment must never come into contact with the surface to be cleaned, such as the ground, which would otherwise blunt the cutting edge of the cutting blade or scratch the surface to be cleaned. Thus, the cutting blades of the known embodiment are typically provided on the surface of the roll brush and are embedded in the bristles and rubber strip. As described above, since the hair is wound on the surface of the roller brush in the most common case, the cutting blades embedded in the bristles and the rubber strip can only reach the hair deep, and the hair wound on the surface of the bristles and the rubber strip of the roller brush cannot be cut, so that there is selectivity for the hair removal area. This selectivity results in the hair removal zone being limited to the base of the bristles and rubber strip and being ineffective for hair that is entangled around the surface of the bristles and rubber strip. Thus, hair removal regimens remain to be further improved.

In view of the above-mentioned problem, the present invention provides a cleaning device for a roller brush of a cleaning device and a cleaning system with the cleaning device, which can solve the above-mentioned problems.

In the embodiment of the utility model, the semi-automatic cleaning and cutting (Cut) mode is used for cleaning the hairs which are possibly unfixed and cause poor cleaning effect, the cutting (Shears) mode is used for automatically cleaning the hairs which are difficult to touch the surface of the rolling brush due to the fact that the blades are buried in the bristles of the rolling brush and are fixed in position, and the like in the prior art, the cutting assembly capable of cutting the hairs is used for cleaning the hairs, and the cutting assembly is arranged to be movable from outside to inside along the radial direction of the rolling brush, so that the hairs wound on the surface and inside of the rolling brush can be better cleaned. Therefore, the cleaning device provided by the embodiment of the utility model has no selectivity on the hair cleaning area, and the hair cleaning effect can be greatly improved.

As described above, with reference to fig. 17, in a specific implementation scenario, the cleaning apparatus 100 according to the embodiment of the present invention may be specifically a base station, and the cleaning apparatus 200 may be a sweeping robot or a dust collection robot, which form the cleaning system 300 according to the embodiment of the present invention. In this embodiment, the sweeping robot or the dust collection robot may automatically return to the base station after finishing the mopping or dust collection task or after receiving the command signal, and perform the operation of rolling brush cleaning while realizing mop replacement and charging in the base station.

Of course, the cleaning apparatus 100 and the cleaning apparatus 200 are not limited to the above-described embodiments. In another possible embodiment, the cleaning apparatus 200 may be any type of vacuum cleaner, such as a hand-held vacuum cleaner, a bucket cleaner, a canister cleaner, an upright cleaner, etc. After the user has used the vacuum cleaner, the vacuum cleaner may be placed on the cleaning apparatus 100 and the cleaning apparatus 100 may perform hair cleaning.

Therefore, when the cleaning device 200 is a self-moving device such as a sweeping robot or a dust-sucking robot, the cleaning device 200 returns to the cleaning device 100 (base station) and is parked on the parking place 4 without manual intervention of the user. In contrast, when the cleaning apparatus 200 is a vacuum cleaner of various types, the user is required to manually place the cleaning apparatus 200 on the parking place 4 of the cleaning apparatus 100.

Also, for convenience of description, the following is set forth in the context of a sweeping robot and a base station. It will nevertheless be understood that no limitation of the scope of the embodiments of the utility model is thereby intended, as illustrated in the accompanying drawings.

As shown in fig. 9, 10, and 14A to 14F, a plurality of groups of ash-raising elements are arranged at intervals on the rolling brush 1 of the cleaning device 200, and an empty region 101 is formed between adjacent ash-raising elements. Taking the sweeping robot as an example, the rolling brush 1 is generally arranged at the bottom of the body of the sweeping robot and is driven to rotate by a motor. The ash-raising components comprise the bristles and the rubber strips, and the vacant areas 101 formed between the adjacent ash-raising components are used for the cutting edges of the cutting components 2 to extend into.

The shape of the vacant areas 101 depends on the shape of the ash lifting member. In some alternative embodiments, the ash lifting elements may be linear, that is, the ash lifting elements extend along the axial direction of the rolling brush 1 and are arranged at intervals along the circumferential direction of the rolling brush 1, and the empty regions 101 defined between adjacent ash lifting elements are linear. Similarly, in alternative embodiments, the ash lifting element may be spiral-shaped, and the vacant areas 101 may also be spiral-shaped. Alternatively, as shown in fig. 9, 10, and 14A to 14F, the ash raising element is V-shaped, and the empty region 101 is correspondingly V-shaped.

As shown in fig. 1, 5, 6, 11 and 12, the cleaning apparatus 100 includes a housing 3 and a parking place 4 formed on the housing 3 for placing the cleaning apparatus 200. Wherein the upper surface of the housing 3 is a flat surface, which forms the parking place 4. Since the shearing module 2 is integrally provided on the housing 3 below the parking place 4, the housing 3 should have a certain height or thickness. In the embodiment where the cleaning device 200 is a sweeping robot or a vacuum robot and the cleaning device 100 corresponds to a base station, the overall shape of the housing 3 of the base station can be seen from fig. 1 and 2 in the known embodiment with the publication number WO2020224542a1, and has an inclined climbing section 302, so that the sweeping robot or the vacuum robot can move to the parking place 4 through the climbing section 302. When the cleaning device 200 is a vacuum cleaner, the user can hold the vacuum cleaner by hand and place the vacuum cleaner on the parking place 4, and the housing 3 at this time may not need to be provided with the climbing section 302.

The cutting assembly 2 is rotatably mounted on the housing 3 and therefore has a standby position (shown in fig. 6 and 11) housed inside the housing 3 and a working position (shown in fig. 7 and 12) at least partially protruding to the parking position 4. As shown in fig. 1 to 5, the cutting assembly 2 of the present embodiment includes a first blade 201, and a second blade 202 movable relative to the first blade 201. That is, the cutting assembly 2 in the present embodiment can perform a cutting (Shears) operation on hairs. The above description describes the cutting method to effectively clean hair compared to the cutting (Cut) method, and is not repeated here.

When the cutting assembly 2 is in the working position, the cutting edges of the first blade 201 and the second blade 202 can extend into the vacant area 101 of the roller brush 1. Further, the cutting assembly 2 is switchable between the standby position and the working position by being driven by the drive assembly. Thus, the cutting assembly 2 of this embodiment is movably arranged compared to the roller brush 1, compared to the known embodiment of the prior art, in which the blades are fixedly arranged on the roller brush and embedded in the bristles. After the cleaning device 200 is placed on the parking place 4, the cutting assembly 2 extends from the housing 3 and moves from the outside to the inside in the radial direction of the roller brush 1 into the empty area 101 of the roller brush 1. Thus, the moving path of the cutting assembly 2 covers the surface and the inner side of the rolling brush 1, so that the hairs wound on the surface and the inner side of the rolling brush 1 can be cleaned, and the hair cleaning effect is better.

As shown in fig. 6, 7, 11 and 12, the housing 3 is provided with an opening 301 leading to the parking place 4, in particular, the opening 301 is provided in the top wall of the housing 3. The shear assembly 2 is disposed in the housing 3 at a position corresponding to the opening 301. When in the standby position, the cutting assembly 2 is at least partially located in the opening 301 with its upper surface flush with the surface of the parking place 4. Specifically, the cutting assembly 2 includes a first blade 201 located outside the second blade 202, the first blade 201 has substantially the same shape as the opening 301, and the first blade 201 is in clearance fit with the opening 301 to ensure that the cutting assembly 2 rotates smoothly. When the cutting assembly 2 is driven in the standby position, the first blade 201 is located exactly in the opening 301, which is now a flat plane. Therefore, the sweeping robot or the dust collection robot can conveniently pass through the cutting assembly 2, and the cutting assembly is prevented from extending to the parking position 4 to block the sweeping robot or the dust collection robot from passing. Moreover, the shearing assembly 2 is flush with the surface of the parking position 4, so that the opening 301 can be filled, the passing path of the sweeping robot or the dust collection robot is ensured to be flat, and the sweeping robot or the dust collection robot is ensured to pass smoothly.

When in the working position, the cutting edges of the first blade 201 and the second blade 202 are exposed to the parking place 4 through the opening 301. Specifically, the shear assembly 2 rotates about its rotational connection point (a support shaft 5 described below) with the housing 3. When switching from the standby position to the operating position, the cutter assembly 2 is rotated outward from a substantially horizontal state. During the rotation, the cutting edges of the first blade 201 and the second blade 202 gradually extend into the vacant region 101 from outside to inside in the radial direction of the roller brush 1. And, the first blade 201 and the second blade 202 are staggered with each other to cut the hair. Thereby, the cleaning of the whole path is performed to the hair wound on the roll brush 1.

As shown in fig. 1-7, 11 and 12, the shear assembly 2 further includes a tool holder 203 disposed in the housing 3. The first blade 201 is arranged on the tool holder 203, and the cutting edge of the second blade 202 is attached to the cutting edge of the first blade 201. Since the first blade 201 and the second blade 202 move relatively to each other to form a shearing action, in practice, at least one of the first blade 201 and the second blade 202 is a moving blade. The method specifically comprises the following steps: one of the first blade 201 and the second blade 202 is a moving blade, and the other is a fixed blade. Alternatively, the first blade 201 and the second blade 202 are both moving blades.

In a specific embodiment, the first blade 201 is a stationary blade fixedly disposed on the blade holder 203. The second blade 202 is a moving blade driven by a reciprocating assembly to reciprocate along its length relative to the first blade 201. As shown in fig. 1 and 2, the reciprocating assembly includes an eccentric that drives the second blade 202 and a motor (not shown) that drives the movement of the eccentric. Specifically, the surface of the second blade 202 facing away from the first blade 201 is provided with two clamping members 204 extending substantially in parallel, the eccentric member comprises a disc or a connecting rod 501 (the connecting rod is arranged substantially perpendicular to the output shaft of the motor) directly driven by the motor to rotate, and a rod body 502 arranged on the disc or the connecting rod 501 and clamped between the two clamping members 204, and the axis of the rod body 502 is parallel to but not coincident with the axis of the output shaft of the motor. Thus, the motor drives the rod 502 eccentrically disposed to move through the disc or the connecting rod 501, and the rod 502 pushes the two clamping members 204 to swing left and right in a reciprocating manner, so as to realize the linear reciprocating movement of the second blade 202 relative to the first blade 201.

As shown in fig. 1 and 2, the tool holder 203 includes two opposite and symmetrical brackets, which are plate-shaped as a whole. The first blade 201 is disposed at the top end of the two supports, and the second blade 202 is disposed below the first blade 201 and between the two supports. In this way, the reciprocating assembly for driving the second blade 202 to reciprocate is also substantially located on the two supports, so as to avoid interference with the first blade 201, and the structural design is reasonable.

A support shaft 5 is provided on the housing 3, and a tool holder 203 is provided on the support shaft 5. Specifically, the two brackets included in the tool holder 203 are provided with shaft holes 2031, and the support shaft 5 is inserted into the shaft holes 2031. In addition, through holes 2041 are formed in the two clamping pieces 204, and the support shaft 5 is movably arranged in the through holes 2041 in a penetrating mode. That is, the support shaft 5 is clearance-fitted with the holder 204 on the second blade 202. Thus, when the second blade 202 is driven to reciprocate, the reciprocating motion of the two clamping pieces 204 can be guided and limited by the clearance fit between the support shaft 5 and the through hole 2041, and the stability of the second blade 202 in motion relative to the first blade 201 is ensured.

In an alternative embodiment, the support shaft 5 may form part of the drive assembly. Specifically, the support shaft 5 is rotatably provided in the housing 3 and is driven to rotate by a motor. The tool rest 203 is fixedly arranged with the supporting shaft 5, so that the supporting shaft 5 can drive the tool rest 203 to rotate, and the cutting assembly 2 arranged on the tool rest 203 is driven to rotate and switch between the standby position and the working position.

As described later, in an embodiment in which the number of the shearing modules 2 is plural and different shearing modules 2 are required to be selectively lifted up to expose the housing 3, the tool holders 203 of the plural shearing modules 2 may be fixedly provided on the support shaft 5 at the same time, and the shearing modules 2 of different groups do not correspond in the axial direction of the support shaft 5, that is, the shearing modules 2 of different groups are arranged in different phases in the circumferential direction. That is, at least two of the plurality of cutting assemblies 2 are configured to be in different positions at the same time, and the at least two cutting assemblies 2 in different positions at the same time correspond to different portions of the vacant region 101. In this way, by controlling the rotation rhythm of the motor, it is possible to realize that different cutting assemblies 2 are in the working position or the standby position, and further to perform hair cleaning on different positions of the empty area 101 of the roll brush 1.

In another alternative embodiment, shown in fig. 6, 7, 11 and 12, the tool holder 203 rotates with the support shaft 5, i.e. the shaft hole 2031 is clearance-fitted with the support shaft 5. The blade holder 203 is provided with a receiving portion 2032. In this embodiment, the driving assembly includes a motor 6 drivingly connected to the support shaft 5 to drive the support shaft to rotate, and a switching member 7 provided on the support shaft 5 and driven to rotate by the support shaft 5. The switch 7 cooperates with the bearing portion 2032 to drive the rotation of the tool holder 203. As shown in fig. 1, one end of the supporting shaft 5 is provided with a transmission member 8, and the transmission member 8 can be a belt pulley, a chain wheel, a gear, etc. to realize transmission connection with the motor 6 through a belt, a chain or a gear, so as to receive the rotation power of the motor 6. As shown in fig. 2, the receiving portion 2032 includes a projection provided on the outside of the bracket. As shown in fig. 8, the switch 7 is disposed substantially perpendicular to the support shaft 5. Therefore, the switching piece 7 and the bearing part 2032 are fixed along the circumferential direction, and when the switching piece 7 is driven to rotate by the support shaft 5, the tool rest 203 is driven to rotate through the circumferential stopping and fixing cooperation of the bearing part 2032 and the switching piece 7, so that the shearing assembly 2 is switched between different positions.

As described above, when the vacant region 101 has an irregular shape such as a V-shape or a spiral shape, it is difficult to clean the hairs in the vacant region 101 with one cutting unit 2 having the same length as the roller brush 1, and it is necessary to clean the hairs in the vacant region 101 with a plurality of cutting units 2 in a plurality of times. In view of this, in order to be able to perform hair cleaning on the vacant areas 101 having irregular shapes such as a V-shape or a spiral shape, in one embodiment, the number of the cutter assemblies 2 is plural, and the support shaft 5 passes through the blade holders 203 of the plural cutter assemblies 2. That is, a plurality of cutter assemblies 2 are provided on the same support shaft 5. The number of the switching pieces 7 is correspondingly multiple, and the switching pieces correspond to the multiple tool holders 203 one by one. As shown in fig. 8, the plurality of switching pieces 7 do not completely correspond one-to-one in the axial direction of the support shaft 5. As described above, the purpose of this design is to lift the different cutting members 2 in their respective working positions in order to perform hair cleaning of different positions of the free space 101, in order to adapt to the hair cleaning of the free space 101 having irregular shapes, such as a V-shape or a spiral shape.

As shown in fig. 9 and 10, in a specific embodiment, the vacant region 101 has a V-shape and includes two first sub-regions symmetrically disposed and one second sub-region connected to the two first sub-regions. The plurality of shearing assemblies 2 are divided into at least two groups, namely two first groups of shearing assemblies and one second group of shearing assemblies, and the shearing assemblies 2 belonging to the same group are not adjacent. As shown in fig. 1, three shearing modules 2 are schematically shown, wherein two shearing modules 2 on the left and right sides are a first group of shearing modules, and the middle one is a second group of shearing modules.

As shown in fig. 8, the switching pieces 7 corresponding to the same group of the shearing modules 2 correspond to each other in the axial direction of the support shaft 5, and the switching pieces 7 corresponding to the different groups of the shearing modules 2 are offset from each other in the axial direction of the support shaft 5. That is, in the circumferential direction of the support shaft 5, the phases of the switches 7 corresponding to the same group of shear assemblies are the same, and the phases of the switches 7 corresponding to the different groups of shear assemblies 2 are different. Alternatively, it can be said that the projections of the switches 7 corresponding to the same group of the shearing modules overlap in the axial direction of the support shaft 5, and the projections are shifted from the switches 7 corresponding to the shearing modules 2 of different groups.

In this way, the switching member 7 corresponding to the same group of cutting assemblies can drive the same group of cutting assemblies 2 to always have the same position or state, thereby ensuring that the same group of cutting assemblies 2 can be simultaneously located at the working position or the standby position. Meanwhile, the switching pieces 7 corresponding to the different groups of the cutting assemblies 2 are staggered along the axial direction of the supporting shaft 5, so that the different groups of the cutting assemblies 2 can be respectively lifted to be positioned at working positions, and the hair in different positions of the vacant area 101 can be cleaned by matching with the rotation of the rolling brush 1.

As shown in fig. 9 and 10, when the roller brush 1 of the cleaning apparatus 200 placed on the parking place 4 is located at the first angular position, the first group of cutter assemblies is in the working position and respectively extends into the two first sub-areas, and the second group of cutter assemblies is in the standby position. At this time, the hairs in the two first sub-areas are cleaned by the two first groups of cutting members. After the hair in the two first sub-areas is cleaned, the motor drives the rolling brush 1 to rotate by a preset angle and then is fixed at a second angle position, the driving assembly drives the cutting assembly 2 to rotate, so that the first group of cutting assembly is switched to a standby position, the second group of cutting assembly is switched to a working position and extends into the second sub-area, and the hair in the first sub-area is cleaned.

The cleaning system 300 also includes a control module for controlling the operation of the shearing assembly 2 and the drive assembly. In an alternative embodiment, as shown in FIG. 15, the control module may be located on the cleaning device 200. Alternatively, the control module may be provided on the cleaning apparatus 100. Alternatively, as shown in fig. 16, in another alternative embodiment, the control module may include two control units: the first control unit and the second control unit are respectively arranged on the cleaning device 200 and the cleaning device 100. The first control unit is used to control the operation of the cutting assembly 2 and the second control unit is used to control the rotation of the roller brush 1. The two control units are in communication connection, can communicate and transmit the state information or the work instruction of the workflow, and execute corresponding control. Thus, the cleaning device 200 and the cleaning device 100 are communicatively connected by the control units respectively provided on the cleaning device 200 and the cleaning device 100. When the cleaning apparatus 200 is placed on the parking place 4, the first control unit controls the driving assembly to operate, so that the cutting assembly 2 is switched from the standby position to the working position, and controls the cutting assembly 2 to operate. Between the cleaning device 200 and the parking place 4 of the cleaning device 100, there is a sensor for sensing the position of the roll brush 1 and controlling the cutting assembly 2 to perform a hair cleaning operation by the first control unit when the roll brush 1 is sensed.

As shown in fig. 9 and 10, specifically, an angular position sensor for detecting the rotation angle of the rolling brush 1 is provided on the housing 3 (more specifically, the parking place 4) of the cleaning apparatus 100, and the sensor communicates with a second control unit that controls the rolling brush 1 to stop at a specified angular position based on an angle detection signal fed back from the sensor. When the sweeping robot or the dust collection robot enters the base station, the sweeping robot or the dust collection robot is positioned at the parking position 4. The second control unit is communicated with the motor through an angle position sensor to control the rolling brush 1 to stop at the first angle position, and the rotating angle position can be accurately fed back through the sensor. After the positioning of the first angular position of the roller brush 1 has been completed, the first control unit then controls the drive assembly to raise the cutting assembly 2 and to perform a deeper cutting cleaning cut of the hair during the raising.

Wherein the first control unit realizes the opening control and the position switching control of the shearing assembly 2 by controlling the motor of the shearing assembly 2 and the motor 6 of the driving assembly. The starting time of the motor of the cutting assembly 2 and the motor 6 of the driving assembly may be the same time, or the motor 6 of the driving assembly may be started before the motor of the cutting assembly 2 according to the above, or the opposite.

When the hair cleaning of the first sub-area is completed, the first control unit controls the operation of the drive assembly, and the motor 6 of the drive assembly continues to rotate in the aforementioned direction or in the opposite direction to drive the first group of cutting assemblies to return to the standby position. And then, after the second control unit controls the motor to drive the rolling brush 1 to rotate to a second angle position, the first control unit controls the driving assembly to operate again, the second group of cutting assemblies are lifted up, the second group of cutting assemblies are switched to the working position and extend into a second sub-area, and hair cleaning is carried out on the second sub-area.

After the hair cleaning of the second sub-area is completed, the control module controls the cutting assembly 2 to stop working and controls the drive assembly to reset the cutting assembly 2 to the standby position. Then, the sweeping robot or the dust collection robot starts the dust collection fan and the rolling brush 1 to rotate, and broken hairs cut on the rolling brush 1 are sucked into the dust box.

That is, after the second control unit controls the rolling brush 1 to rotate and stop at the first designated angle position, the second control unit sends a first control signal for starting cleaning to the first control unit. The first control unit controls the cutting assembly 2 to switch from the standby position to the working position based on the first control signal, and then controls the cutting assembly 2 to start the cleaning operation. When the cutting assembly 2 operates at the working position for a preset time, the first control unit controls the cutting assembly 2 to be switched to the standby position again, and sends a second control signal for switching the angle position of the rolling brush to the second control unit. The second control unit controls the rolling brush 1 to rotate and stop at the second designated angle position based on the second control signal, then sends a third control signal for starting cleaning again to the first control unit, and the first control unit controls the shearing assembly 2 to be switched to the working position based on the third control signal. And so on until the number of times the cutter assembly 2 is reset reaches the set value, indicating that the hair-clearing operation of all the empty areas 101 of the roller brush 1 is completed.

In yet another alternative embodiment, switching of the position of the shear assembly 2 may be accomplished using magnetic attraction or repulsion between magnetic elements. In this embodiment, the tool holder 203 is rotatably provided on the support shaft 5. The drive assembly comprises a first switching element provided on the cutting assembly 2 and a second switching element provided on the housing 3 and corresponding to the first switching element. One of the first switching element and the second switching element is a magnetic element, and the other is an electromagnetic element. The electromagnetic element is electrically connected with the power supply, and a change-over switch capable of changing the current direction is arranged between the electromagnetic element and the power supply.

In this embodiment, the magnetic element may be a magnetic element capable of generating a magnetic field, for example, a magnet with magnetism, such as a permanent magnet or a hard magnet. Because the structure of the electromagnetic element is complex, the weight is generally heavier than that of the magnetic element. Therefore, in order to reduce the weight of the cutter unit 2 and to enable smooth rotation of the cutter unit 2 to switch the positions, it is possible to provide a relatively heavy electromagnetic element in the housing 3 and a relatively light magnetic element in the blade holder 203.

Because a change-over switch capable of changing the current direction is arranged between the electromagnetic element and the power supply, the magnetic pole direction of the electromagnetic element can be changed. That is, the electromagnetic element is controllable facing the poles of the magnetic element. Therefore, the magnetic pole of the magnetic element facing the electromagnetic element is arbitrary, and may be an N pole or an S pole. As long as the current direction is changed according to the requirement, the electromagnetic element can realize the attraction or the repulsion to the magnetic element, and further realize the position switching of the shearing assembly 2.

Specifically, when the electromagnetic element and the magnetic element are opposite in polarity to each other, the shearing assembly 2 is maintained at the standby position or has a tendency to move from the operating position to the standby position by the magnetic attraction force. When the polarities of the electromagnetic element and the magnetic element facing each other are the same, the shearing assembly 2 is maintained at the working position or has a tendency to switch the movement from the standby position to the working position by the repulsive force of the magnetic force.

In this embodiment, the switch may be any feasible configuration, such as a double-pole double-throw switch, which is not limited in this embodiment.

In a specific application scenario, assuming that the magnetic pole of the magnetic element facing the electromagnetic element is the N pole, the shearing module 2 is in the standby position in the initial state. When the cleaning device 200 is placed on the parking position 4 and the cutting assembly 2 needs to be switched to the working position, the electromagnetic element is energized, and the current direction is controlled so that the magnetism of the electromagnetic element facing the magnetic element is N-pole. The cutting assembly 2 is rotated from the standby position to the operating position by the magnetic repulsion force. The electromagnetic element may remain energized during the entire hair cleaning process, and the cutting assembly 2 is maintained in the working position by the magnetic repulsion force. After hair is cleaned, the current direction is changed by switching the switch, the magnetism of the electromagnetic element facing the magnetic element is changed from N pole to S pole, and the electromagnetic element and the magnetic element on the knife rest 203 generate magnetic attraction, so that the cutting assembly 2 is driven to move to the standby position. After the cutting assembly 2 is reset to the standby position, the power can be cut off, so that the cutting assembly 2 is kept at the standby position by utilizing the gravity and the structural design of the cutting assembly. Of course, after the shear unit 2 is returned to the standby position, the electromagnetic element may be kept in the energized state, and the shear unit 2 may be placed in the standby position by the magnetic attraction force.

In a specific application scenario where the magnetic pole of the other magnetic element facing the electromagnetic element is the S pole, reference may be made to the above description, which is not repeated herein.

Also, in this embodiment, in order to accommodate the hair cleaning requirements of the irregular vacant areas 101, the number of the cutting assemblies 2 may be plural, the plurality of cutting assemblies 2 may be divided in the same group as above, the cutting assemblies 2 classified into the same group may be controlled to be in the working position or the standby position at the same time, and the cutting assemblies 2 classified into different groups may be controlled to be in different positions at the same time.

The hair cleaning is performed on the irregular vacant area 101 by arranging the plurality of cutting assemblies 2, grouping the plurality of cutting assemblies 2 into different groups and matching with the rotating rhythm of the rolling brush 1. Of course, to achieve hair cleaning of the irregular empty regions 101, it is not limited to the above-described embodiment. In other possible embodiments, only one cutting assembly 2 is provided, which also achieves the above-mentioned functions. Specifically, as shown in fig. 11 and 12, a linear assembly may be disposed on the housing 3, and the cutting assembly 2 is disposed on the linear assembly and can be driven by the linear assembly to move along the axial direction of the roller brush 1.

In this embodiment, the linear assembly can be any structure capable of driving the cutting assembly 2 to move along the axial direction of the roller brush 1, such as a synchronous belt, various types of telescopic assemblies, e.g., an electric telescopic rod, a hydraulic cylinder, etc. Taking the timing belt as an example, the timing belt is wound around a pulley, which is rotatably provided on the housing 3 and driven by a motor. The cutting assembly 2 is fixed on the synchronous belt, and a driving assembly for driving the cutting assembly 2 to switch positions is also arranged on the synchronous belt.

As shown in fig. 14A to 14F, the vacant region 101 is non-linear in the axial direction of the roll brush 1 and includes a plurality of sub-regions. Unlike the V-shaped vacant region 101 in the above embodiment that is divided into two first sub-regions and one second sub-region, the vacant region 101 in this embodiment is not limited to the V-shape, and the number of sub-regions included in the vacant region is not limited to three. In specific implementation, the blank region 101 may be divided according to the length of the cutting assembly 2, as long as the projection length of each sub-region along the axial direction of the roller brush 1 is not less than the length of the cutting assembly 2.

In order to perform hair cleaning for the plurality of sub-areas, respectively, the roll brush 1 is driven to have a plurality of rest positions corresponding one-to-one to the plurality of sub-areas. The shearing module 2 is driven by the driving module to have a plurality of operations of switching to the working position in one-to-one correspondence with the plurality of sub-areas. Thus, after the cleaning device 200 is placed on the parking place 4, by controlling the rotation of the rolling brush 1, the cutting assembly 2 is intermittently driven to lift up and respectively clean the hair of each sub-area, and then the hair of the irregular vacant area 101 can be cleaned by the cutting assembly 2.

To achieve the above purpose, in the present embodiment, the driving assembly includes a profiling portion 9 and an abutting member 10, as shown in fig. 13. The copying portion 9 is provided on the housing 3 and has an uneven copying surface 901. The abutting piece 10 is arranged on the shearing assembly 2 and is in sliding abutting contact with the profiling surface 901. The abutting element 10 may be a ram, and may be disposed on the tool rest 203 of the shearing assembly 2, and an end portion of the abutting element contacting with the contoured surface 901 is spherical or arc-shaped to reduce friction therebetween. When the shearing assembly 2 is driven by the linear assembly to move along the axial direction of the rolling brush 1, the abutting piece 10 arranged on the shearing assembly 2 slides on the profiling surface 901, and along with the concave-convex fluctuation of the profiling surface 901, the abutting piece 10 is applied with a reaction force, so that the shearing assembly 2 is forced to rotate, and the position switching is realized.

Specifically, when the abutting member 10 abuts against the convex surface of the cam surface 901, the abutting member 10 is pressed downward, and the cutting assembly 2 is driven to rotate clockwise in fig. 11 and 12, and is switched to the operating position. When the abutting member 10 abuts against the concave surface of the curved surface 901, the abutting member 10 is lifted up, and the cutting unit 2 is driven to rotate counterclockwise in fig. 11 and 12, and is switched to the standby position. Wherein, when the abutting member 10 abuts against the convex surface of the profiling surface 901, the cutting assembly 2 is in the working position. Thus, the number of convexities of the contoured face 901 is equal to the number of sub-areas.

As shown in fig. 14A to 14F, when the cutting member 2 is lifted up and enters the first sub-area of the vacant area 101 along the left side, the first sub-area is subjected to hair cleaning. After the hair cleaning of the first sub-area is finished, the cutting assembly 2 is driven by the straight line assembly to move rightwards along the axial direction of the rolling brush 1. At the same time, under the cooperation of the abutting member 10 and the profiling surface 901, the cutting assembly 2 is lowered and then returns to the working position again, and the roller brush 1 is also driven to rotate through a certain angle, so that the cutting assembly 2 can perform hair cleaning on the second sub-area at the optimal position. And analogizing in turn until the cutting component 2 is driven by the straight line component to move to the right end of the rolling brush 1, and finishing the hair cleaning of the last subregion.

That is, after the cleaning operation of the cleaning device 100 in the previous working position is completed, the control module controls the motor to drive the roller brush 1 to rotate by a preset angle, and controls the linear assembly to drive the shearing assembly 2 to move to the next working position along the axial direction of the roller brush 1. Until the cleaning of all the working positions is finished. Therefore, when the cutter unit 2 cleans the roll brush 1, the roll brush 1 is driven to rotate at least once during switching of the cutter unit 2 from the operating position to the standby position or during switching from the standby position to the operating position.

The workflow of the cleaning system 300 of the embodiment of the present invention is further explained with reference to fig. 18 below:

the cleaning device 100 (base station) is powered on to detect whether the parking place 4 is parked with the cleaning device 200 (sweeping robot or dust collection robot). After the cleaning device 200 is parked on the parking place 4, detecting whether the rolling brush 1 is in place; if not, the roller brush 1 may be driven to rotate until the roller brush 1 is in place.

After the roller brush 1 is in place, the cleaning device 200 communicates with the cleaning device 100, and the control module (specifically, the first control unit) controls a motor (simply referred to as a blade position motor) for driving the cutting assembly 2 to rotate to work, so as to drive the cutting assembly 2 to extend out of the housing 3, that is, to switch the cutting assembly 2 from an original standby position to a working position. During the switching of the cutting assembly 2 to the position, it is detected whether the cutting assembly 2 is in place. After detecting that the cutting assembly 2 is rotated to the position, the first control unit continues to control the motor (simply referred to as a cutting motor) driving the cutting assembly 2 to operate to start, and the cutting assembly 2 performs a hair cleaning operation on the roller brush 1. The cutting motor is stopped after working for a predetermined time (for example, 2s), the cleaning device 200 starts the dust suction fan to suck the cut broken hairs into the dust box, and the first round of hair cleaning operation is completed. Then, the blade position motor again rotates the cutter unit 2, and the cutter unit 2 is returned to the standby position. When the cutting assembly 2 is reset, it is counted by a counter, the counted number being essentially the number of hair cleanings of one empty area 101. The number of times may be set according to actual conditions, for example, 3 times, which is not limited in this embodiment.

When the counted times do not reach the set value, the shearing assembly 2 can be repeatedly lifted or put down. When the number of resets of the cutting assembly 2 reaches the set value, it is indicated that the hair cleaning of the same empty area 101 has been completed. Subsequently, the cleaning device 100 communicates with the cleaning device 200, the first control unit of the cleaning device 100 sends a command signal for cleaning the second empty area 101 to the second control unit of the cleaning device 200, and the second control unit controls the roller brush 1 to rotate and stop at a specified angle position under the trigger of the command signal. Subsequently, the cleaning device 100 performs the hair cleaning operation for the second empty area 101 in the same steps as described above. And so on, the operation is not performed until the hair cleaning of all the vacant areas 101 of the roll brush 1 is completed.

The above description is only a few embodiments of the present invention, and those skilled in the art can make various changes or modifications to the embodiments of the present invention according to the disclosure of the application document without departing from the spirit and scope of the present invention.
