The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 and 2 are schematic structural views of a cleaning apparatus according to an embodiment of the present invention. As shown in fig. 1, the cleaning apparatus includes: cleaning member 5, air supply unit 2 and recovery unit 3. As shown in fig. 3 and 4, the cleaning member 5 includes a first air duct 501, a second air duct 502, and a rolling brush assembly 52. The first port 5011 of the first air duct 501 is located at the front side of the rolling brush assembly 52; the second port 5021 of the second air duct 502 is positioned at the rear side of the rolling brush assembly 52; in any one of the first air duct 501 and the second air duct 502, one air duct is provided with blowing air flow, and the other air duct is provided with suction air flow; any air channel communicated with the suction air flow is communicated with the suction air source supply end of the air supply assembly 2 through the recovery assembly 3; the other air channel communicated with the blowing air flow is communicated with the blowing air source supply end of the air supply assembly 2.
What needs to be explained here is: the user typically will be in front of the user when using the cleaning element. The user uses the cleaning device, typically to propel forward for cleaning. Thus, both the front and rear sides referred to in embodiments of the present invention may be user-friendly in terms of the use of the cleaning device. The front side of the roller brush assembly can be simply understood as: one side of the roller brush assembly remote from a user operating the cleaning device; the rear side of the roller brush assembly can be simply understood as: the side of the roller brush assembly that is closest to the user operating the cleaning device.
According to the technical scheme provided by the embodiment of the invention, the air duct communicated with the air blowing air flow is additionally arranged in the cleaning component, the air blowing air flow can blow a cleaning object (such as dust or sewage) into the cleaning range of the rolling brush in advance, and the cleaning object is cleaned to the air duct port communicated with the air suction air flow through the rolling brush so as to suck the cleaning object into the recovery component, so that the primary cleaning efficiency is improved; in addition, the drying of the cleaned surface can be accelerated after the blowing air flow is increased, and the cleaning effect is good.
In one possible technical solution, the first air duct and the second air duct may be set as follows. As shown in fig. 3 and 4, the first air duct 501 extends from the upper rear side of the rolling brush assembly 52 to the lower front side of the rolling brush assembly 52 along the outer contour of the front side of the rolling brush assembly 52; the second air duct 502 extends from the lower rear side of the rolling brush assembly 52 to a direction away from the rolling brush assembly 52.
The second air duct may be an air suction duct of an existing cleaning device, such as a dust collector or a cleaning machine, and the specific structure and the setting position thereof may be referred to in the prior art, which is not described herein.
Further, as shown in fig. 3 and 4, the first port of the first air duct 501 faces the first area formed on the front side of the rolling brush assembly 52 and the surface to be cleaned; the first port of the second air duct 502 faces the second area formed by the rolling brush assembly and the cleaned surface at the rear side. The first region of the roller brush assembly 52 formed on the front side and the second region formed on the rear side of the surface to be cleaned (e.g., floor surface), i.e., the cleaning region of the roller brush assembly 52. The air blowing port faces the cleaning area of the rolling brush assembly, particles or sewage can be effectively blown to the cleaning area due to the action of air flow, and the rolling brush assembly cleans the particles or sewage and faces the cleaning area due to the air suction port, so that the particles or sewage can smoothly enter the air duct through the air suction port until being sucked into the recovery assembly, and the cleaning efficiency of the cleaning equipment is improved.
In order to further improve the dust blowing efficiency of the air blowing flow and the dust collection efficiency of the dust collection flow, in an achievable technical scheme, a tangential drainage structure is arranged at a first end opening of the first air channel so as to guide the air blowing flow or the air suction flow to flow along the tangential direction of the circular arc.
Specifically, the tangential drainage structure can be realized by adopting the following structure:
as shown in fig. 5 and 6, a side of the first end opening 5011 of the first air duct 501 near the rolling brush assembly is a first side 50111, a side of the first end opening 5011 of the first air duct 501 opposite to the first side 50111 is a second side 50112, and an edge of the second side 50112 opening exceeds an edge of the first side 50111 opening. As shown in fig. 6, the crossing excess portion of the second side 50112 is bent toward the rolling brush assembly to form the tangential drainage structure. Still further, as shown in fig. 6, the inner wall of the crossing at the first side 50111 may further be provided with a drainage cambered surface bent toward the rolling brush assembly. Alternatively, as shown in fig. 5, the inner wall of the crossing exceeding part of the second side 50112 is provided with a tangential guide surface bent toward the rolling brush assembly to form the tangential drainage structure.
With continued reference to fig. 1 and 2, the cleaning component provided by the present invention further includes a housing 520 and a drive assembly 59 housed within the housing 520; the roller brush assembly 52 is disposed outside the housing 520. The driving end of the driving component 59 is exposed out of the outer cover 520 and is connected with the rolling brush component 52 to provide power for the rolling brush component 52; the housing 520 is provided with a first interface 511 which is communicated with the first air duct 501, and a second interface (not shown) for connecting an air supply assembly; an air flow channel is connected between the first interface 511 and the second interface, and is disposed in the housing.
Specifically, as shown in fig. 2, two opposite ends of the front side of the outer cover extend out of the first connecting arm and the second connecting arm respectively. The rolling brush assembly is rotatably fixed on the front side of the outer cover through the first connecting arm and the second connecting arm. The driving end of the driving assembly may be exposed outside the housing 520 through the first connecting arm or the second connecting arm, so as to be conveniently connected with the rolling brush assembly to provide rotary power for the rolling brush assembly.
In a specific implementation, the first interface 511 is provided on a front side cover wall of the cover (as shown in fig. 2); the second interface is provided on a rear side wall of the housing (not shown). Of course, the setting position of the second interface is not specifically limited in the embodiment of the present invention. In particular embodiments, the location of the second interface may be considered based on the angle at which the air supply assembly is conveniently connected.
As shown in fig. 2, the first air duct provided in the embodiment of the present invention may be implemented by the following structure. As shown in fig. 2, the first air duct 501 includes: an air duct upper cover 54 and an air duct lower cover 53 connected to the air duct upper cover 54; the air duct lower cover 53 is covered on the roller brush assembly 52 and is connected with the outer cover 520 over the rear side of the roller brush assembly 52 through the air duct upper cover 54.
The air duct lower cover 53 may be fixed on the air duct upper cover 54 by gluing, and the air duct upper cover 54 is fixed on the outer cover 520 by a connecting member such as a screw. In particular, as shown in fig. 2, the housing 520 includes a cleaning upper cover 51 and a cleaning lower cover 55. The cleaning upper cover 51 may be provided with a first interface 511, and the duct upper cover 54 may be fixed to the cleaning upper cover 51. The cleaning upper cover 51 and the cleaning lower cover 55 are buckled to form a containing cavity for containing components (such as the driving assembly 59, the water spraying assembly 57, the water pump 510 and the second air duct 502).
In a specific implementation, as shown in fig. 7, the air duct lower cover 53 includes: an arc-shaped bottom plate 531 adapted to the outer contour of the rolling brush assembly; the two opposite sides of the arc-shaped bottom plate 531 are respectively a first side 5311 and a second side 5312. As shown in fig. 2 and 3, the first edge 5311 corresponds to above the rear side of the roller brush assembly; the second edge 5312 corresponds to a front underside of the roller brush assembly; a first wall plate 532 extending from the first edge 5311 in a direction away from the roller brush assembly; the first wall plate 532 is provided with a second port 533 of the first air duct 501. As shown in fig. 2, the second port 533 of the first air duct 501 is in communication with the first port 511 of the housing 520; the air duct upper cover 54 is covered on the air duct lower cover 53, and is fixedly connected with the air duct lower cover 53 to form the first air duct.
What needs to be explained here is: when the second end opening of the first air channel is in butt joint with the first interface on the outer cover, in order to ensure sealing, a sealing ring can be arranged between the second end opening of the first air channel and the first interface so as to seal a butt joint gap when the second end opening of the first air channel is in butt joint with the first interface.
Further, as shown in fig. 2, the cleaning apparatus further includes a communicating pipe 4; a pipe joint 58 is connected to the second interface; one end of the communicating pipe 4 is connected to the suction air source supply end of the air supply assembly 2, and the other end is connected to the air flow passage in the housing 520 through the pipe joint 58 to communicate with the first air duct 501.
In particular embodiments, the coupling 58 may be a first removable coupling. The second end opening of the second air duct can be provided with a second detachable pipe joint. Through setting up first detachable pipe joint and second detachable pipe joint, can dismantle the mode of butt joint according to actual need to change the air current flow direction in first wind channel and the second wind channel in the clean subassembly. For example:
when the second air duct 502 is filled with the suction air flow and the first air duct 501 is filled with the blowing air flow, as shown in fig. 8, a second port of the second air duct 502 is connected with the recovery inlet of the recovery assembly 3 through the second detachable pipe joint 5022. As shown in fig. 9, the second connector 511 is connected to the supply end of the blowing air source of the air supply assembly 2 through the first detachable pipe joint to introduce the blowing air into the first air duct 501. At this time, the rolling brush assembly should be rotated for the second, so that the air blowing air current blows the particles or sewage to the rear side of the rolling brush assembly to blow into the cleaning area of the rolling brush assembly, and the rolling brush assembly is rotated for the second air duct sweeping the particles or sewage to the rear side to enter the recycling assembly through the second air duct, thereby forming the blowing and sucking system.
The second air duct is communicated with the blowing air flow, when the first air duct is communicated with the suction air flow, a corresponding diagram is not shown, a second end opening of the second air duct is communicated with a blowing air source supply end of the air supply assembly through the second detachable pipe joint so as to introduce the blowing air flow into the second air duct, and the second interface is connected with a recovery inlet of the recovery assembly through the first detachable pipe joint. At this time, the rolling brush assembly should rotate in a first direction, and the first direction is clockwise, so that the air blowing air flow blows particles or sewage to the front side at the rear side of the rolling brush assembly to blow into the cleaning area of the rolling brush assembly, and the rolling brush assembly rotates in the first direction to sweep the particles or sewage into the first air duct at the front side, so that the particles or sewage enters the recovery assembly through the first air duct, and a reverse sweeping and sucking system is formed.
In the technical scheme provided by the embodiment of the invention, the air supply assembly for providing the air suction source and the air blowing source can be realized by adopting two fans, for example, one fan provides the air suction source; the other fan provides a blowing air source. Or the air supply assembly is formed by adopting a fan assembly, namely, the air discharged by the fan assembly is used as an air blowing source. Namely, the air supply assembly is a fan assembly; the air suction source supply end is an air suction output end of the fan assembly; the blowing air source supply end is an exhaust end of the fan assembly. The air exhausted by the fan assembly is used as an air blowing source, so that the structure is simplified, and the air exhausted by the fan is fully utilized; and the air exhausted by the fan is generally higher than the room temperature, so that the air exhausted by the fan is blown to the ground to further accelerate the drying of the cleaned surface.
Further, as shown in fig. 1, the cleaning apparatus provided by the embodiment of the present invention further comprises an upright handle assembly 1 connected to the cleaning member. The air supply assembly 2 and the recovery assembly 3 are arranged on the vertical handle assembly 1; the air supply assembly 2 is positioned above the recovery assembly 3; the recovery assembly 3 is located above the cleaning member 5; the blowing air source supply end of the air supply assembly is communicated with the first air duct or the second air duct through a communicating pipe 4 arranged outside the vertical handle assembly 1. In particular embodiments, the cleaning element may be pivotally coupled to the upright handle assembly to permit relative rotation of the cleaning element with respect to the upright handle assembly for ease of use by a user.
As can be seen from the above, when the airflow direction in the first air duct and the second air duct is changed, the rotation direction of the corresponding rolling brush assembly may need to be changed. Of course, in the implementation, a control key is provided on the cleaning device, and a user can control the direction of the rotation power provided by the driving component to the rolling brush component by touching the control key. But this has a problem: when the user forgets to switch the rotation direction by touch, the cleaning effect of the cleaning device is affected. Therefore, the embodiment of the invention provides the following scheme for automatic switching. That is, as shown in fig. 10, the cleaning unit provided in the embodiment of the present invention may further include: the device comprises a driving assembly, a sensor for monitoring the airflow direction in the first air duct or the second air duct and a controller. The controller is respectively connected with the driving assembly and the sensor, and is used for determining whether the rotating direction of the rolling brush assembly is changed according to the airflow direction sensing information uploaded by the sensor, and sending a corresponding control instruction to the driving assembly to drive the rolling brush assembly to rotate along the rotating direction pointed by the control instruction when the rotating direction of the rolling brush assembly is determined to be changed.
The control flow of the controller will be described in detail hereinafter.
It should be noted that, the driving assembly may be a motor assembly, and a specific implementation of the motor assembly may be referred to in the prior art, which is not described herein. In addition, the specific implementation structures of the rolling brush assembly, the water spraying assembly and the like in the embodiments of the present invention can refer to various structures in the prior art, and are not repeated herein.
In addition, the cleaning device provided in the embodiment of the present invention may be a dust collector, a cleaning machine, etc., which is not particularly limited in the embodiment of the present invention. What is needed here is that: when the cleaning device provided by the embodiment of the invention is a cleaning machine, as shown in fig. 2, the cleaning device further includes: a water pump 510 accommodated in the housing and a water spray assembly 57 connected to the water pump; the water pump is communicated with a water tank arranged on the vertical handle assembly through a water pipe extending into the shell. Specifically, the position setting and structure of the water pump, the water spraying assembly and the water tank can be referred to in the prior art, and the details are not repeated here.
Fig. 11 is a flow chart illustrating a method for controlling a rotation direction of a rolling brush assembly according to an embodiment of the invention. The method provided in this embodiment needs to be implemented based on the structure provided in each embodiment. Specifically, the method comprises the following steps:
101. the airflow direction in the first air duct or the second air duct of the cleaning component is obtained.
102. Providing corresponding control instructions to the driving assembly according to the airflow direction in the first air duct or the second air duct so as to control the driving assembly to drive the rolling brush assembly to rotate along the rotating direction pointed by the control instructions;
wherein the cleaning component comprises the first air duct, the second air duct and the rolling brush assembly; the first end opening of the first air duct is positioned at the front side of the rolling brush assembly; the second end opening of the second air duct is positioned at the rear side of the rolling brush assembly; any one of the first air channel and the second air channel is communicated with blowing air flow, and the other air channel is communicated with suction air flow; the air channel communicated with the air suction flow is communicated with the air suction source supply end of the air supply assembly through the recovery assembly; the air duct through which the blowing air flow is communicated with the blowing air source supply end of the air supply assembly.
In order to further improve the dust blowing efficiency of the air blowing flow and the dust collection efficiency of the dust collection flow, in an achievable technical scheme, a tangential drainage structure is arranged at a first end opening of the first air channel so as to guide the air blowing flow or the air suction flow to flow along the tangential direction of the circular arc.
Specifically, the tangential drainage structure can be realized by adopting the following structure: as shown in fig. 5 and 6, a side of the first end opening 5011 of the first air duct 501 near the rolling brush assembly is a first side 50111, a side of the first end opening 5011 of the first air duct 501 opposite to the first side 50111 is a second side 50112, and an edge of the second side 50112 opening exceeds an edge of the first side 50111 opening. As shown in fig. 6, the crossing excess portion of the second side 50112 is bent toward the rolling brush assembly to form the tangential drainage structure. Still further, as shown in fig. 6, the inner wall of the crossing at the first side 50111 may further be provided with a drainage cambered surface bent toward the rolling brush assembly. Alternatively, as shown in fig. 5, the inner wall of the crossing exceeding part of the second side 50112 is provided with a tangential guide surface bent toward the rolling brush assembly to form the tangential drainage structure. What needs to be explained here is: the specific implementation of the structural features and the connection relationship between the structural features in this embodiment may refer to the corresponding content in each embodiment, which is not described herein.
Based on the above embodiments, it can be seen that the air flow directions of the first air channel and the second air channel are opposite, i.e. when the first air channel is filled with the air suction air flow, the second air channel is filled with the air blowing air flow; when the second air channel is filled with the air suction air flow, the first air channel is filled with the air blowing air flow. Therefore, in the above 101, only the airflow direction of any one of the first duct and the second duct may be monitored.
In 101, the airflow direction in the first duct or the second duct may be sensed by a sensor disposed in the corresponding duct. The sensor is used for upwards transmitting the sensed airflow to the controller, and the controller can know the airflow direction in the first air duct or the second air duct based on the sensing information uploaded by the sensor. For example, when the cleaning device is started, the sensor senses the airflow direction in the first air duct or the second air duct, and then the sensed sensing information is uploaded to the controller, so that the controller can know the airflow direction in the first air duct or the second air duct based on the received sensing information.
In practice, the correspondence between airflow direction and rotation direction may be preconfigured. In 102, the controller may obtain a rotation direction corresponding to the airflow direction in the first air duct or the second air duct based on the pre-configured correspondence between the airflow direction and the rotation direction, and then provide a control instruction corresponding to the rotation direction to the driving component to control the driving component to drive the rolling brush component to rotate along the rotation direction pointed by the control instruction.
In one implementation solution, the step 102 may specifically include:
when the airflow direction in the first air channel is the air suction direction or the airflow direction in the second air channel is the air blowing direction, providing a first rotating instruction to the driving assembly to control the driving assembly to drive the rolling brush assembly to rotate in a first direction which is clockwise;
when the airflow direction in the first air channel is the blowing direction or the airflow direction in the second air channel is the air suction direction, a second rotating instruction is provided for the driving assembly to control the driving assembly to drive the rolling brush assembly to rotate in a second direction, and the second direction is a counterclockwise direction.
According to the technical scheme provided by the embodiment of the invention, the air duct communicated with the air blowing air flow is additionally arranged in the cleaning component, the air blowing air flow can blow a cleaning object (such as dust or sewage) into the cleaning range of the rolling brush in advance, and the cleaning object is cleaned to the air duct port communicated with the air suction air flow through the rolling brush so as to suck the cleaning object into the recovery component, so that the primary cleaning efficiency is improved; in addition, the drying of the cleaned surface can be accelerated after the blowing air flow is increased, and the cleaning effect is good. In addition, the technical scheme provided by the embodiment of the invention also provides a scheme for controlling the rotation direction of the rolling brush assembly based on the airflow direction condition in the air duct, so that the diversity of working modes of the cleaning equipment is increased, and the cleaning effect is improved for different impurities.
It should be noted that: the execution subjects of the steps of the method provided in the above embodiment may be the same apparatus (the controller mentioned in the above embodiment), or the method may be executed by a different apparatus. For example, the execution subject of steps 101 to 102 may be device a; for another example, the execution body of step 101 may be device a, and the execution body of step 102 may be device B; etc.
