Description

Technical Field

[0001] This utility model relates to the field of home cleaning technology, specifically to floor brushes and cleaning equipment. Background Technology

[0002] With the development of society and economy and people’s increasing requirements for home environment, cleaning equipment that integrates floor washing, mopping and vacuuming has emerged and is widely used in people’s lives. The cleaning equipment of this technology usually achieves the cleaning of the floor by driving the roller brush to rotate at high speed by a motor. However, the existing cleaning equipment has the problems of the roller brush bristles wearing out quickly, the cleaning effect gradually deteriorating, and the roller brush needing to be replaced frequently. Utility Model Content

[0003] In view of this, the present invention provides a floor brush and cleaning device to solve the problem of rapid wear of the brush bristles in existing cleaning devices.

[0004] Firstly, this utility model provides a floor brush for use in cleaning equipment, the floor brush comprising:

[0005] case;

[0006] A roller brush assembly, including a roller brush rotatably disposed in a housing;

[0007] The cleaning mechanism, movably mounted in the housing, is used to scrape off dirt from the roller brush;

[0008] The drive unit, in transmission cooperation with the scraping mechanism, is used to drive the scraping mechanism to move between the scraping position that contacts and cooperates with the roller brush and the clearance position that cooperates with the gap of the roller brush.

[0009] The cleaning equipment has a working mode and a self-cleaning mode:

[0010] When the cleaning equipment is in working mode, the drive unit drives the scraping mechanism to move to the scraping position;

[0011] When the cleaning equipment is in self-cleaning mode, the cleaning equipment is located inside the base station, and the drive device drives the scraping mechanism to move to an avoidance position.

[0012] Beneficial effects: During normal cleaning operation, the drive unit moves the scraping mechanism to a position where it contacts and engages with the roller brush, effectively cleaning the dirt adhering to the brush bristles. After cleaning, the entire unit is placed on the base station. Upon receiving a self-cleaning command, the drive unit moves the scraping mechanism to a position where it avoids contact with the roller brush, thus separating the scraping mechanism from the brush. This avoids the problem of excessive contact during self-cleaning, which would lead to rapid bristle wear. This invention, while ensuring the scraping performance of the scraping mechanism, allows it to avoid contact with the roller brush during self-cleaning, reducing friction between them, increasing the roller brush's lifespan, reducing replacement frequency, and saving replacement costs.

[0013] In one optional embodiment, the drive device includes a drive mechanism and a gear transmission mechanism, wherein the gear transmission mechanism is driven between the drive mechanism and the scraping mechanism.

[0014] The drive mechanism drives the scraping mechanism to move between the scraping position that contacts and engages with the roller brush and the clearance position that engages with the gap between the roller brush and the roller brush through a gear transmission mechanism.

[0015] Beneficial effects: By using a gear transmission mechanism as the transmission mechanism to drive the scraping mechanism, the structure is not only simple, but also the transmission is precise and reliable with high efficiency, enabling the scraping mechanism to move accurately and efficiently between the scraping position and the avoidance position.

[0016] In one alternative embodiment, the scraping mechanism is rotatably mounted to the housing, and the drive mechanism is fixedly mounted to the housing;

[0017] The gear transmission mechanism includes:

[0018] The drive gear is fixed on the output shaft of the drive mechanism;

[0019] The driven gear meshes with the scraping mechanism, and the drive mechanism drives the driving gear and the driven gear to rotate, thereby causing the scraping mechanism to rotate between the scraping position and the avoidance position.

[0020] Beneficial effects: The scraping mechanism is rotatably mounted on the housing. When the cleaning equipment switches between working mode and self-cleaning mode, the scraping mechanism can be controlled by the drive device to rotate between the scraping position and the avoidance position. This ensures that the scraping mechanism can be separated from the roller brush during the self-cleaning process while maintaining its scraping performance. This reduces friction between the scraping mechanism and the roller brush and extends the service life of the roller brush. The scraping mechanism moves between the scraping position and the avoidance position by rotation, which takes up less space compared to translation.

[0021] In one alternative implementation, the drive mechanism includes:

[0022] The drive motor has an output shaft;

[0023] The motor bracket is fixedly installed on the housing, and the drive motor is mounted on the motor bracket.

[0024] The gear transmission mechanism also includes a gear cover, which is assembled and connected to the motor bracket to limit the driving gear and the driven gear between itself and the motor bracket.

[0025] Beneficial effects: The gear cover can cooperate with the motor bracket to limit the driving gear and driven gear between them, reducing the risk of the driving gear and driven gear falling off and improving the stability of the driving gear and driven gear operation.

[0026] In one alternative implementation, the floor brush further includes:

[0027] The position detection mechanism is used to send corresponding sensing signals when the scraping mechanism moves to the scraping position and the avoidance position, so as to limit the scraping stroke of the scraping mechanism.

[0028] Beneficial effects: Through the set position detection mechanism, when the drive device drives the scraping mechanism to the scraping position and the avoidance position, it can send the corresponding arrival signal. When the controller of the cleaning equipment receives the arrival signal, it controls the drive device to stop driving, thereby achieving precise control of the position of the scraping mechanism, ensuring the accuracy of the scraping stroke, and avoiding the phenomenon of excessive or insufficient movement of the scraping mechanism when moving between the scraping position and the avoidance position. This avoids affecting the scraping cleaning effect of the scraping mechanism on the roller brush, or the scraping mechanism and roller brush not being able to separate effectively in self-cleaning mode, and the brush bristles still having wear problems.

[0029] In one alternative embodiment, the position detection mechanism includes a first position switch, a second position switch, and a trigger.

[0030] When the cleaning mechanism moves to the cleaning position, the trigger can activate the first position switch;

[0031] When the scraping mechanism moves to the avoidance position, the trigger can activate the second position switch.

[0032] Beneficial effects: When the cleaning equipment receives a cleaning command, the drive unit drives the scraping mechanism to rotate to the scraping position. At this time, the trigger can activate the first position switch. When the cleaning equipment receives the trigger signal from the first position switch, it controls the drive unit to stop driving the scraping mechanism to rotate, so that the scraping mechanism remains in the scraping position. At this time, the roller brush is controlled to rotate at high speed, and the scraping mechanism can clean the dirt on the roller brush, scraping off the dirt, and then sucking it away by the suction mechanism, ensuring the scraping performance of the scraping mechanism. When the whole machine is placed in the base station and receives a self-cleaning command, the drive unit drives the scraping mechanism to rotate to the avoidance position. At this time, the trigger can activate the second position switch. When the cleaning equipment receives the trigger signal from the second position switch, it controls the drive unit to stop driving the scraping mechanism to rotate, so that the scraping mechanism remains in the avoidance position. At this time, the scraping mechanism is disengaged from the roller brush to avoid friction.

[0033] In one alternative implementation, the scraping mechanism includes:

[0034] The support is rotatably mounted on the housing, and the support is provided with a meshing part for engaging with the drive device for transmission.

[0035] The scraper is detachably mounted on the support and has several scraping teeth for scraping dirt off the bristles of the roller brush.

[0036] Beneficial effects: The meshing part provided on the support can be used to drive the entire scraping mechanism to rotate between the scraping position and the avoidance position by meshing transmission between the meshing part and the drive device; the scraper can be detachably installed and fixed on the support, which is convenient for disassembly and assembly.

[0037] In one alternative embodiment, the scraping mechanism further includes:

[0038] The reset element, mounted on the support, is used to apply a force to the support to drive the scraper to move closer to the roller brush.

[0039] Beneficial effects: By setting a reset component on the support, when the force of the drive mechanism on the scraping mechanism is removed, the reset component can drive the scraper to rotate towards the roller brush, so that the scraping mechanism automatically resets to the scraping position, which facilitates the normal operation of subsequent scraping work. At the same time, it can also avoid the phenomenon that the scraping mechanism is highly flexible and will rotate randomly and be unstable in position.

[0040] In one alternative embodiment, the reset element includes a torsion spring, with its two ends abutting against the housing and the support, respectively.

[0041] Furthermore, there are two torsion springs, which are located at both ends of the support.

[0042] Beneficial effects: The reset component adopts a torsion spring structure, which requires less installation space and is easier to install than conventional springs, and provides a more stable and reliable elastic holding force. In addition, by setting two torsion springs at both ends of the support, the problem of torsion that is prone to occur in the scraping mechanism with a torsion spring on one side can be effectively avoided, further improving the balance and stability of the scraping mechanism during the reset process.

[0043] Secondly, this utility model also provides a cleaning device, including a body and a floor brush of any of the above embodiments installed at the bottom of the body. Attached Figure Description

[0075] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0076] Existing cleaning equipment typically uses comb-shaped scrapers fixed to one side of the roller brush for easy cleaning, or employs floating scrapers propelled by a spring. This allows the scraper to remove dirt from the roller brush as it rotates at high speed. To achieve the desired cleaning effect, an interference fit is required between the scraper and the roller brush to effectively remove dirt. However, under the motor's drive, this prolonged interference fit easily causes wear on the brush bristles. As a result, the bristles gradually shorten, the gap between the scraper and the roller brush increases, and the cleaning effect gradually diminishes.

[0077] However, during the self-cleaning process on the base of the cleaning equipment, that is, the roller brush rotates forward and backward to clean the roller brush cover, there is no need for a scraper to clean the dirt on the roller brush. However, a fixed scraper or a floating scraper cannot effectively avoid the roller brush, which causes the scraper and the roller brush to rub against each other for a long time. This causes the bristles on the roller brush to shorten due to long-term friction, reducing their service life. In addition, the gap between the scraper and the roller brush increases, which will also affect the cleaning effect of the cleaning equipment in the long run.

[0078] In related technologies, to ensure the cleaning effect of the roller brush, the distance between the scraper and the brush bristles is controlled within a certain range. However, during self-cleaning on the base station, it is not necessary to clean the dirt. This process takes a long time, leading to prolonged wear on the bristles and roller brush, necessitating the scraper and bristles to be kept apart. Currently, the industry mostly addresses the problem of easily worn roller brushes and gradually deteriorating cleaning effects by replacing the roller brushes. This method involves high replacement frequency and high costs.

[0079] The following is combined Figures 1 to 20 The following describes embodiments of the present invention.

[0080] According to an embodiment of the present invention, in one aspect, the present invention provides a floor brush 101, applied to a cleaning device 100. The floor brush 101 includes a housing 10, a roller brush assembly 20, a scraping mechanism 30, and a driving device 40. The roller brush assembly 20 includes a roller brush 21 rotatably disposed in the housing 10. The scraping mechanism 30 is movably disposed in the housing 10 and is used to scrape dirt off the roller brush 21. A drive mechanism 40 is driven to move the scraping mechanism 30 between a scraping position that contacts the roller brush 21 and a clearance position that is in clearance with the roller brush 21. The cleaning device 100 has a working mode and a self-cleaning mode: when the cleaning device 100 is in the working mode, the driving device 40 drives the scraping mechanism 30 to move to the scraping position; when the cleaning device 100 is in the self-cleaning mode, the cleaning device 100 is located inside the base station 200, and the driving device 40 drives the scraping mechanism 30 to move to the clearance position.

[0081] In the above embodiments, when the cleaning device 100 is performing normal cleaning work, the drive device 40 drives the scraping mechanism 30 to move to a scraping position that contacts and cooperates with the roller brush 21, which can effectively clean the dirt attached to the bristles of the roller brush 21. After the cleaning work is completed, the whole device is placed on the base station 200. When a self-cleaning command is received, the drive device 40 can drive the scraping mechanism 30 to move to a clearance position that is in close contact with the roller brush 21, thereby separating the scraping mechanism 30 from the roller brush 21 and avoiding the problem of excessive contact between the two in the self-cleaning mode, which would lead to rapid wear of the bristles. Under the premise of ensuring the scraping performance of the scraping mechanism 30, this utility model can avoid the roller brush 21 during the self-cleaning process, reduce the friction between the scraping mechanism 30 and the roller brush 21, improve the service life of the roller brush 21, reduce the replacement frequency of the roller brush 21, and save replacement costs.

[0082] In some embodiments, the drive device 40 includes a drive mechanism 41 and a gear transmission mechanism 42, the gear transmission mechanism 42 being driven between the drive mechanism 41 and the scraping mechanism 30; the drive mechanism 41 drives the scraping mechanism 30 to move between a scraping position that contacts and engages with the roller brush 21 and a clearance position that is in close contact with the roller brush 21.

[0083] In the above embodiment, the gear transmission mechanism 42 is used as the transmission mechanism to drive the scraping mechanism 30 to move. This not only has a simple structure, but also precise and reliable transmission and high transmission efficiency, enabling the scraping mechanism 30 to move precisely and efficiently between the scraping position and the avoidance position.

[0084] Specifically, to improve the scraping effect on the roller brush 21, when the scraping mechanism 30 is in the scraping position, the bristles of the roller brush 21 are in an interference fit. When not cleaning, to reduce friction between the scraping mechanism 30 and the roller brush 21, when the scraping mechanism 30 is in the clearance position, the gap between the scraping mechanism 30 and the bristles of the roller brush 21 is greater than a set distance.

[0085] In some embodiments, the scraping mechanism 30 is rotatably mounted on the housing 10, and the drive mechanism 41 is fixedly mounted on the housing 10; the gear transmission mechanism 42 includes a driving gear 421 and a driven gear 422, the driving gear 421 is fixed on the output shaft of the drive mechanism 41; the driven gear 422 meshes and drives between the driven gear 422 and the scraping mechanism 30, and the drive mechanism 41 drives the driving gear 421 and the driven gear 422 to rotate, so as to drive the scraping mechanism 30 to rotate between the scraping position and the avoidance position.

[0086] In the above embodiment, the scraping mechanism 30 is rotatably mounted on the housing 10. When the cleaning device 100 switches between the working mode and the self-cleaning mode, the scraping mechanism 30 can be controlled to rotate between the scraping position and the avoidance position by the drive device 40. In this way, while ensuring the scraping performance of the scraping mechanism 30, it can also ensure that the scraping mechanism 30 is separated from the roller brush 21 during the self-cleaning process, thereby reducing the friction between the scraping mechanism 30 and the roller brush 21 and improving the service life of the roller brush 21. The scraping mechanism 30 moves between the scraping position and the avoidance position by rotation, which occupies less space than the translation method.

[0087] Of course, in other alternative embodiments, the scraping mechanism 30 can also be slidably disposed on the housing 10. For example, the scraping mechanism 30 can be translatably disposed within the housing 10, and can be driven by the driving mechanism 41 to move between the scraping position and the avoidance position.

[0088] In some embodiments, the drive mechanism 41 includes a drive motor 411 and a motor bracket 412, the drive motor 411 having an output shaft; the motor bracket 412 is fixedly mounted on the housing 10, and the drive motor 411 is mounted on the motor bracket 412; the gear transmission mechanism 42 also includes a gear cover 43, which is assembled and connected to the motor bracket 412 to limit the driving gear 421 and the driven gear 422 between itself and the motor bracket 412.

[0089] In the above embodiment, the gear cover 43 can cooperate with the motor bracket 412 to limit the driving gear 421 and the driven gear 422 between them, reducing the risk of the driving gear 421 and the driven gear 422 falling off and improving the stability of the operation of the driving gear 421 and the driven gear 422.

[0090] Specifically, the motor bracket 412 includes a motor housing and a gear mounting portion. The gear mounting portion includes a mounting plate fixedly disposed on one side of the motor housing. The mounting plate is vertically arranged, and a connecting shaft for mounting a driven gear 422 is fixedly disposed on the mounting plate. The driven gear 422 is rotatably mounted on the connecting shaft. The mounting plate also has an opening for the output shaft of the drive motor 411 to extend through. The output shaft of the drive motor extends through the opening and is connected and fixed to the driving gear 421. Bolt posts are provided on the motor bracket 412, and the gear cover 43 is fixed to the bolt posts of the motor bracket 412 by screws 46.

[0091] Furthermore, the drive device 40 also includes a motor bracket cover 413. The motor bracket 412 has a mounting groove for accommodating the drive motor 411. The mounting groove is open at the top. The motor bracket cover 413 is detachably installed and fixed at the opening of the mounting groove, sealing the drive motor 411 within the mounting groove. Optionally, the housing 10 includes an upper housing 11, a lower housing 12, and a middle cover plate 13 disposed between the upper housing 11 and the lower housing 12. The middle cover plate 13 and the lower housing 12 enclose a mounting space for the drive mechanism 41 to be installed. The drive mechanism 41 is fixed on the lower housing 12.

[0092] In some embodiments, the floor brush 101 further includes a position detection mechanism for issuing corresponding sensing signals when the scraping mechanism 30 moves to the scraping position and the avoidance position, so as to limit the scraping stroke of the scraping mechanism 30.

[0093] In the above embodiment, by setting a position detection mechanism, when the drive device 40 drives the scraping mechanism 30 to move to the scraping position and the avoidance position, it can send a corresponding arrival signal. When the controller of the cleaning device 100 receives the arrival signal, it controls the drive device 40 to stop driving, thereby achieving precise control of the position of the scraping mechanism 30, ensuring the accuracy of the scraping stroke, and avoiding the phenomenon of excessive or insufficient movement of the scraping mechanism 30 when moving between the scraping position and the avoidance position. This avoids affecting the scraping and cleaning effect of the scraping mechanism 30 on the roller brush 21, or the scraping mechanism 30 and the roller brush 21 not being effectively separated in the self-cleaning mode, and the brush bristles still having wear problems.

[0094] Optionally, the position detection mechanism can take the form of a distance sensor, photoelectric sensor, infrared sensor, position switch, etc. The position detection mechanism can be mounted on the drive unit 40, the scraping mechanism 30, or the housing 10.

[0095] In some embodiments, the position detection mechanism includes a first position switch 44, a second position switch 45, and a trigger 4211; when the scraping mechanism 30 moves to the scraping position, the trigger 4211 can trigger the first position switch 44; when the scraping mechanism 30 moves to the avoidance position, the trigger 4211 can trigger the second position switch 45.

[0096] In the above embodiments, when the cleaning device 100 receives a cleaning command, the driving device 40 drives the scraping mechanism 30 to rotate to the scraping position. At this time, the trigger 4211 can trigger the first position switch 44. When the cleaning device 100 receives the trigger signal from the first position switch 44, it controls the driving device 40 to stop driving the scraping mechanism 30 to rotate, so that the scraping mechanism 30 remains in the scraping position. At this time, the roller brush 21 is controlled to rotate at high speed, so that the scraping mechanism 30 can clean the dirt on the roller brush 21, scrape off the dirt, and suck it away by the suction mechanism, ensuring the scraping performance of the scraping mechanism 30. When the whole machine is placed in the base station 200 and receives a self-cleaning command, the driving device 40 drives the scraping mechanism 30 to rotate to the avoidance position. At this time, the trigger 4211 can trigger the second position switch 45. When the cleaning device 100 receives the trigger signal from the second position switch 45, it controls the driving device 40 to stop driving the scraping mechanism 30 to rotate, so that the scraping mechanism 30 remains in the avoidance position. At this time, the scraping mechanism 30 is disengaged from the roller brush 21 to avoid friction.

[0097] Optionally, the trigger 4211 is disposed on the scraping mechanism 30 or the drive device 40, and the first position switch 44 and the second position switch 45 are disposed on the side wall of the housing 10 or the drive device 40.

[0098] Furthermore, the drive device 40 includes a rotating part and a fixed part, wherein the fixed part is fixed to the housing 10, the rotating part includes, but is not limited to, an output shaft, a driving gear 421, and a driven gear 422, and the fixed part includes, but is not limited to, a motor bracket 412, a gear cover 43, and other structures. The first position switch 44, the second position switch 45, and the trigger 4211 can all be disposed on the drive mechanism 41; or, the position switch and the trigger 4211 can both be disposed on the gear transmission mechanism 42; or, one of the position switch and the trigger 4211 can be disposed on the drive mechanism 41, and the other can be disposed on the gear transmission mechanism 42.

[0099] In some preferred embodiments, the first position switch 44 and the second position switch 45 are disposed on the gear cover 43, and the trigger 4211 is disposed on the drive gear 421. By disposing the first position switch 44 and the second position switch 45 on the gear cover 43, compared to disposing them on the motor bracket 412, more installation space is available, making the assembly and maintenance of the first position switch 44 and the second position switch 45 more convenient. By disposing the trigger 4211 on the drive gear 421, compared to disposing it on the driven gear 422, the rotational speed of the drive motor 411 can be fed back more directly without conversion, resulting in a more timely response and more precise and efficient control.

[0100] Of course, in other alternative embodiments, the first position switch 44 and the second position switch 45 can also be disposed on the housing 10 or the motor bracket 412, and the trigger 4211 can also be disposed on the driven gear 422 or the scraping mechanism 30. In this embodiment, the specific positions of the first position switch 44, the second position switch 45 and the trigger 4211 are not limited.

[0101] Furthermore, in some embodiments, the first position switch 44 and the second position switch 45 are disposed on the side wall of the gear cover 43 away from the driving gear 421 and the driven gear 422; the trigger 4211 is a trigger rod fixedly disposed on the driving gear 421, and the gear cover 43 is provided with an opening 430 through which the trigger rod can pass and which can avoid the movement of the trigger rod.

[0102] In the above embodiment, by placing the position switch on the outer wall of the gear cover 43, the back space of the gear cover 43 can be fully utilized, improving space utilization and making the overall structure more compact. Simultaneously, it effectively avoids the problem of the position switch interfering with the movement of the driving gear and driven gear 422 if placed on the inner wall of the gear cover 43. The trigger element 4211 adopts a trigger rod structure, which is simple in structure and easy to process. The opening 430 in the gear cover 43, allowing the trigger rod to pass through while avoiding its movement, facilitates the trigger rod's engagement with the first position switch 44 and the second position switch 45.

[0103] Specifically, the trigger rod is fixedly disposed on the outer periphery of the drive gear 421, and is fixedly disposed on the side wall of the drive gear 421 facing the gear cover 43. Preferably, the trigger rod and the drive gear 421 are integrally machined. Further, the opening 430 on the gear cover 43 is an arc-shaped opening, and the trigger rod can move in an arc-shaped trajectory within the opening 430.

[0104] Furthermore, the gear cover 43 is provided with mounting posts 431 for mounting the first position switch 44 and the second position switch 45. The gear cover 43 is provided with two sets of mounting posts 431, and the two sets of mounting posts 431 are used to install the two position switches respectively. Each set of mounting posts 431 includes two mounting posts 431 spaced apart. Each position switch is provided with two mounting through holes. The first position switch 44 and the second position switch 45 are sleeved on the mounting posts 431 through the two mounting through holes. By using the above method to install the first position switch 44 and the second position switch 45, not only can the stability of the structure of the first position switch 44 and the second position switch 45 be guaranteed, but it is also convenient to disassemble and assemble. When you want to disassemble, you can simply remove the position switch from the mounting post 431. When installing, you can simply put it on the mounting post 431.

[0105] Optionally, the first position switch 44 and the second position switch 45 are mechanical switches. Preferably, the first position switch 44 and the second position switch 45 are micro switches. When the drive gear 421 rotates, it drives the trigger element 4211 to move along a predetermined arc trajectory. The first position switch 44 and the second position switch 45 are arranged at intervals on the gear cover 43 corresponding to this arc trajectory. The two inner sidewalls of the first position switch 44 and the second position switch 45 are respectively provided with trigger parts. When the trigger element 4211 moves under the drive of the drive gear, it can trigger these trigger parts, thereby triggering the first position switch 44 and the second position switch 45. Preferably, the trigger part is a trigger spring.

[0106] In this embodiment, the assembly process of the drive device 40 is as follows: the drive motor 411 is placed in the mounting slot of the motor bracket 412, the motor bracket cover 413 is fastened to the slot of the motor bracket 412, the drive gear 421 is installed on the output shaft of the drive motor 411, the support ring 414 is sleeved on the output shaft to press down the drive gear 421, then the driven gear 422 is installed on the motor bracket 412, and the gear cover 43 and the motor bracket 412 are used to press down the driven gear 422. Then the gear cover 43 is fixed to the motor bracket 412 with screws 46, and the first position switch 44 and the second position switch 45 are assembled on the gear cover 43. The entire drive device 40 is then assembled.

[0107] In some embodiments, the scraping mechanism 30 includes a support 31 and a scraper 32. The support 31 is rotatably mounted on the housing 10 and is provided with a meshing part 310 for engaging with the drive device 40. The scraper 32 is mounted on the support 31 and is provided with a plurality of scraping teeth for scraping dirt off the bristles of the roller brush 21.

[0108] In the above embodiment, the meshing part 310 provided on the support 31 can be used to drive the entire scraping mechanism 30 to rotate between the scraping position and the avoidance position by meshing the meshing part 310 and the gear transmission mechanism 42.

[0109] Specifically, the meshing part 310 is a sector gear disposed on the support 31. Preferably, the sector gear is integrally formed with the support 31. The scraper 32 can be installed and fixed on the support 31 by screws or snap-fit. Preferably, the scraper 32 is fixed on the support 31 by screws. The scraper 32 is detachably installed and fixed on the support 31 for easy disassembly and assembly.

[0110] In some embodiments, the scraping mechanism 30 further includes a reset member 314, which is disposed on the support 31 and is used to apply a force to the support 31 to drive the scraper 32 to move toward the roller brush 21.

[0111] In the above embodiment, by using the reset member 314 provided on the support 31, when the force exerted by the drive mechanism 41 on the scraping mechanism 30 is removed, the reset member 314 can drive the scraper 32 to rotate toward the roller brush 21, so that the scraping mechanism 30 automatically resets to the scraping position, which facilitates the normal operation of subsequent scraping work. At the same time, it can also avoid the phenomenon that the scraping mechanism 30 is highly flexible and will rotate randomly and be unstable in position.

[0112] In some embodiments, the reset member 314 includes a torsion spring, the two ends of which abut against the housing 10 and the support 31 respectively; and there are two torsion springs, which are disposed at both ends of the support 31.

[0113] In the above embodiments, the reset member 314 adopts a torsion spring structure, which requires less installation space and is easier to install than conventional springs, and provides a more stable and reliable elastic holding force. In addition, by setting two torsion springs at both ends of the support 31, the problem of torsion that easily occurs in the scraping mechanism 30 with a torsion spring on one side can be effectively avoided, and the balance and stability of the scraping mechanism 30 during the reset process can be further improved.

[0114] Specifically, the support 31 has two mounting shafts at both ends, and the torsion spring is installed on the two mounting shafts respectively. The two torsion arms of the torsion spring abut against the support 31 and the housing 10 respectively.

[0115] Furthermore, two second rotating shafts are fixedly provided at both ends of the support 31, and rotating bushings 313 are rotatably sleeved on the two second rotating shafts. The rotating bushings 313 are connected to the housing 10, thereby realizing the rotational connection between the support 31 and the housing 10. The scraping mechanism 30 also includes a baffle plate 33 and a pressure plate 34. The support 31 includes a front cover 311 and a rear cover 312. The scraper 32 is located on the front side of the support 31. The second rotating shaft and the mounting shaft are both formed on the rear cover 312. The bottom of the rear cover 312 is provided with mounting holes for mounting the scraper 32. The assembly process of the scraping mechanism 30 is as follows: First, the front cover 311 and the rear cover 312 are glued together to prevent water leakage. Then, the two rotating bushings 313 are respectively fitted onto the two second rotating shafts at both ends of the rear cover 312. Then, the two torsion springs are respectively fitted onto the mounting shafts at both ends of the rear cover 312. Then, the scraper 32 is assembled into the corresponding mounting holes of the rear cover 312. Then, the baffle plate 33 is pressed onto the scraper 32. Then, the pressure plate 34 is pressed onto the baffle plate 33 and fixed with four screws.

[0116] In some embodiments, the roller brush assembly 20 further includes a roller brush cover 22, which is movably disposed in the housing 10 and located on one side of the roller brush 21. The scraping mechanism 30 and the roller brush cover 22 are linked and cooperated. When the scraping mechanism 30 moves to the avoidance position, it can drive the roller brush cover 22 to rotate towards the roller brush 21, so that the roller brush cover 22 and the roller brush 21 are kept in close contact. At this time, controlling the forward and reverse rotation of the roller brush 21 can realize the self-cleaning of the roller brush cover 22.

[0117] In the above embodiment, by linking the scraping mechanism 30 with the roller brush cover 22, when the cleaning device 100 performs self-cleaning, the scraping mechanism 30 can not only move to a clearance position to avoid the roller brush 21, reducing friction between them, improving the service life of the roller brush 21, and reducing the replacement frequency of the roller brush 21, but also drive the roller brush cover 22 to a position that contacts and fits with the roller brush 21, thereby cleaning the dirt on the roller brush cover 22. Only one drive device 40 is needed to control the movement of the two components, the scraping mechanism 30 and the roller brush cover 22, saving control costs, simplifying control steps, and effectively solving the problem that the self-cleaning device 100 in the related technology requires a separate drive mechanism 41 to drive the scraping mechanism 30 and the roller brush cover 22, which makes the control process cumbersome and costly.

[0118] In this embodiment, the roller brush cover 22 is located above the roller brush 21. The roller brush cover 22 and the scraping mechanism 30 can be driven by a linkage mechanism or directly contacted to achieve linkage. When the cleaning equipment 100 is performing normal cleaning work, the roller brush 21 rotates at high speed, and the scraping mechanism 30 is in a scraping position with an interference fit with the bristles of the roller brush 21, which can promptly scrape off the dirt on the bristles. At this time, there is a set gap between the roller brush cover 22 and the roller brush 21, and the dirt on the roller brush 21 that has not been scraped off by the scraping mechanism 30 can be thrown onto the roller brush cover 22 under the action of centrifugal force. When the cleaning device 100 completes the cleaning work, it is placed in the base station 200. At this time, since the roller brush 21 no longer performs cleaning work, the scraping mechanism 30 does not need to clean the roller brush 21. The scraping mechanism 30 moves to a position that avoids the gap between the brush bristles of the roller brush 21. At this time, the roller brush cover 22 rotates downward under the linkage of the scraping mechanism 30 and keeps in close contact with the roller brush 21. Then, by controlling the forward and reverse rotation of the roller brush 21, the dirt attached to the roller brush cover 22 is self-cleaned.

[0119] In some embodiments, the roller brush cover 22 is rotatably disposed on the housing 10, and the scraping mechanism 30 is provided with a linkage component 301; the linkage component 301 is limited to the roller brush cover 22 to convert the movement of the scraping mechanism 30 into the power for the roller brush cover 22 to rotate toward or away from the roller brush 21.

[0120] In the above embodiment, through the linkage component 301 provided on the scraping mechanism 30 and the roller brush cover 22 in a limiting cooperation, when the scraping mechanism 30 moves to the avoidance position, the roller brush cover 22 can be rotated to the self-cleaning position in contact with the roller brush 21 under the drive of the linkage component 301, thereby facilitating the roller brush 21 to clean the roller brush cover 22; when the scraping mechanism 30 moves to the scraping position, the roller brush cover 22 can be rotated to the initial position in clearance cooperation with the roller brush 21 under the drive of the linkage component 301 and / or the action of the elastic reset component, thereby effectively ensuring that when the cleaning equipment 100 is performing normal cleaning work, there is a set gap between the roller brush cover 22 and the roller brush 21, and it will not interfere with the movement of the roller brush 21.

[0121] Specifically, when the scraping mechanism 30 moves to the avoidance position, the linkage component 301 can convert the movement of the scraping mechanism 30 into downward pressure applied to the roller brush cover 22, causing the roller brush cover 22 to contact and engage with the roller brush 21. The limiting engagement between the linkage component 301 and the roller brush cover 22 can include, but is not limited to, hinge, hook, and abutment. For example, the linkage component 301 can adopt a hinge seat, pull ring, hook, protrusion, or other structural forms.

[0122] In some embodiments, the roller brush cover 22 includes a roller brush cover body 221 and a connecting portion 222; one end of the connecting portion 222 is fixed to the roller brush cover body 221, the other end is limitedly engaged with the linkage component 301, and the middle part is rotatably connected to the housing 10; when the scraping mechanism 30 moves to the scraping position, the roller brush cover body 221 can rotate away from the roller brush 21 under the drive of the linkage component 301; when the scraping mechanism 30 moves to the avoidance position, the linkage component 301 can push the roller brush cover body 221 to rotate closer to the roller brush 21 through the connecting portion 222.

[0123] In the above embodiments, the roller brush cover 22, through the design of the connecting part 222, can both achieve a rotatable connection between the roller brush cover 22 and the housing 10, and can also cooperate with the linkage component 301 to achieve linkage between the roller brush cover 22 and the scraping mechanism 30, thus achieving multiple functions and further simplifying the structure. In addition, by adopting a method in which the connecting part 222 is rotatably connected to the housing 10 in the middle and cooperates with the roller brush cover body 221 and the scraping mechanism 30 at both ends respectively, the entire roller brush cover 22 forms a lever-like structure, which can change the direction of force. This allows the scraping mechanism 30 to drive the roller brush cover body 221 to move downward and fit tightly against the roller brush 21 when pushing the connecting part 222 upward. This not only makes the position of the scraping mechanism 30 unrestricted and facilitates the installation layout of the scraping mechanism 30, but also allows the scraping mechanism 30 to drive the roller brush cover 22 more easily and effortlessly.

[0124] Specifically, the main body 221 of the roller brush cover is an arc-shaped plate structure, and the middle part of the connecting part 222 is provided with a first shaft hole. The first shaft hole and the housing 10 are connected by a first rotating shaft 23 to realize the rotational connection between the roller brush cover 22 and the housing 10. Of course, in other alternative embodiments, the middle part of the connecting part 222 can be integrally formed with the first rotating shaft 23.

[0125] When the cleaning equipment 100 is performing normal cleaning work, the scraping mechanism 30 moves to the scraping position. At this time, the roller brush cover body 221 can rotate away from the roller brush 21 under the drive of the linkage component 301, so as to avoid interfering with the high-speed rotating roller brush 21. When the cleaning equipment 100 performs self-cleaning, the scraping mechanism 30 moves to the avoidance position. At this time, the linkage component 301 can push the roller brush cover body 221 to rotate closer to the roller brush 21 through the connecting part 222, so that the roller brush cover body 221 and the bristles of the roller brush 21 come into contact and cooperate. At this time, the dirt on the inner wall of the roller brush cover body 221 can be cleaned by controlling the forward and reverse rotation of the roller brush 21.

[0126] In some embodiments, combined with Figures 18 to 20 As shown, the linkage component 301 is a push-up protrusion provided on the scraping mechanism 30, and the push-up protrusion abuts against the roller brush cover 22.

[0127] In the above embodiments, the linkage component 301 adopts a push-up protrusion, which has a simple structure and is easy to process and form. The linkage between the scraping mechanism 30 and the roller brush cover 22 is achieved by the push-up protrusion abutting against the roller brush cover 22. Compared with the hinge or hook method, the linkage method is simpler and more reliable, and it is also convenient for disassembly, assembly and maintenance.

[0128] Furthermore, the main body 221 of the roller brush cover has an inner sidewall facing the roller brush 21 and an outer sidewall facing away from it. The connecting part 222 is a connecting rib fixedly provided on the outer sidewall, and the connecting rib abuts against the push protrusion. The connecting part 222, by adopting the form of a connecting rib fixedly provided on the outer sidewall of the main body 221 of the roller brush cover, has a simple structure and is easy to process and form.

[0129] Specifically, the linkage component 301 is a protrusion fixedly mounted on the scraping mechanism 30. The connecting rib includes a shaft portion located in the middle and a first arm and a second arm portion arranged at a set angle on both sides of the shaft portion. A shaft hole is provided in the shaft portion. The end of the first arm portion is fixed on the outer wall of the roller brush cover body 221. The end of the second arm portion is constructed as an abutting end suitable for abutting and cooperating with the linkage component 301.

[0130] In some embodiments, along the axial direction of the roller brush 21, two sets of connecting portions 222 are provided at both ends of the roller brush cover body 221; two sets of linkage components 301 are provided accordingly, and the two sets of linkage components 301 and the two sets of connecting portions 222 are matched one-to-one.

[0131] In the above embodiment, by providing two sets of connecting portions 222 at both ends of the roller brush cover body 221 and two sets of corresponding linkage components 301, the two sets of linkage components 301 and the two sets of connecting portions 222 are in one-to-one contact and cooperation, thereby enabling the roller brush cover body 221 to be pushed from both sides, making the movement of the roller brush cover body 221 more balanced and stable.

[0132] In some embodiments, the roller brush assembly 20 further includes a first rotating shaft 23 and an elastic reset member 24. The connecting portion 222 is rotatably connected to the housing 10 via the first rotating shaft 23. The elastic reset member 24 is disposed on the first rotating shaft 23 and is capable of applying a reset force to the roller brush cover body 221 in a direction away from the roller brush 21.

[0133] In the above embodiment, the elastic reset member 24 provided on the first rotating shaft 23 enables the roller brush cover 22 to have a tendency to rotate away from the roller brush 21. When the scraping mechanism 30 moves to the scraping position and no longer presses down on the roller brush cover 22, the elastic reset member 24 can give the roller brush cover body 221 an upward reset force, so that the roller brush cover 22 can automatically reset to the initial position of clearance matching with the roller brush 21, thereby effectively ensuring the normal operation of the cleaning work.

[0134] Preferably, the elastic reset member 24 is a torsion spring, which is sleeved on the first rotating shaft 23. The two ends of the torsion spring abut against the roller brush cover body 221 and the housing 10, respectively. When the pushing protrusion does not push up the connecting part 222 and presses down on the roller brush cover body 221, the torsion spring can give the roller brush cover body 221 an upward reset force, so that the gap between the roller brush cover body 221 and the roller brush 21 is restored, so as to carry out normal cleaning work.

[0135] Of course, in other alternative implementations, the elastic reset member 24 may also be a tension spring, and this embodiment does not limit this.

[0136] In this embodiment, along the circumferential direction of the roller brush cover body 221, the connection position between the connecting rib and the roller brush cover body 221 is located on one side of the arc-shaped roller brush cover body 221. When the scraping mechanism 30 moves to the avoidance position, the linkage component 301 moves upward, pushing the second arm of the connecting rib to rotate upward. Under the action of the lever, the first arm of the connecting rib drives the roller brush cover body 221 to rotate downward, pressing down the roller brush cover body 221, so that the roller brush cover body 221 and the roller brush 21 come into contact and cooperate. When the scraping mechanism 30 moves to the scraping position, the linkage component 301 moves upward, and the second arm falls down under the action of the elastic reset component 24. Under the action of the lever, the first arm drives the roller brush cover body 221 to rotate upward, lifting the roller brush cover body 221, so that the roller brush cover body 221 and the roller brush 21 disengage from contact and form a set gap.

[0137] In some embodiments, the roller brush assembly 20 further includes a sealing strip 25, which is disposed on the inner edge of the roller brush cover body 221. The sealing strip 25 enables a sealing fit between the roller brush cover body 221 and the middle cover plate 13 of the housing 10, preventing dirt from being thrown from between the roller brush cover body 221 and the middle cover plate 13 of the housing 10 to other positions inside the housing 10, thus affecting the hygiene of the entire machine.

[0138] According to an embodiment of the present invention, in another aspect, a cleaning device 100 is provided, including a body 102 and a floor brush 101 of any of the above embodiments mounted on the bottom of the body 102.

[0139] Preferably, in this embodiment, the cleaning equipment 100 is a floor scrubber.

[0140] The following description, in conjunction with the accompanying drawings, details the assembly steps of the floor brush 101, the working process of the cleaning equipment 100, and the control method of this embodiment.

[0141] 1. The assembly process of the floor brush 101 is as follows:

[0142] The drive unit 40 is fixed to the lower housing 12 of the housing 10 with screws; the meshing part 310 of the scraping mechanism 30 is meshed with the driven gear 422 of the drive unit 40 and assembled at the front end of the lower housing 12; then the middle cover plate 13 is used to press down the scraping mechanism 30; then the roller brush 21 is installed at the front end of the scraping mechanism 30; then the roller brush cover 22 is installed on top of the roller brush 21 to cover the roller brush 21 and the scraper 32. The floor brush 101 of the cleaning equipment 100 is now assembled.

[0143] 2. The working process of cleaning equipment 100 is as follows:

[0144] When the cleaning equipment 100 is cleaning the floor normally, the drive motor 411 drives the scraping mechanism 30 to rotate and move forward. After reaching the scraping position, the scraper 32 can effectively clean the dirt. After cleaning, the whole machine is placed on the base station 200 and the self-cleaning mode is activated. At this time, the drive motor 411 drives the active gear 421 and the driven gear 422 to move, causing the scraping mechanism 30 to rotate and move backward to the avoidance position, so that the scraper 32 separates from the roller brush 21 and avoids interference. At the same time, the linkage component 301 on the scraping mechanism 30 moves, causing the roller brush cover 22 to rotate downward and keep in close contact with the roller brush 21. At this time, the roller brush 21 self-cleans in both directions. The scraping mechanism 30 moves to the avoidance position, which can not only avoid the roller brush 21 and avoid friction between the scraper 32 and the roller brush 21, thus improving the service life of the roller brush 21, but also make the roller brush cover 22 fit with the roller brush 21, thus cleaning the dirt on the roller brush cover 22.

[0145] Furthermore, during the floor cleaning process of the cleaning equipment 100, the drive motor 411 drives the drive gear 421, which in turn drives the driven gear 422. The driven gear 422 drives the scraper 32 to rotate forward and contact the roller brush 21 through the meshing part 310 on the scraping mechanism 30 (due to limited space, only a limited meshing part of the gear is left, so the meshing part 310 is made into a sector gear). When the trigger 4211 on the drive gear 421 touches the first position switch 44, the drive motor 411 stops moving, and the scraper 32 rotates to the foremost position. At this time, the roller brush 21 will rotate at high speed, and the scraper 32 will clean the dirt on the roller brush 21, scraping off the dirt, and then sucking it away through the suction chamber.

[0146] After the floor scrubber finishes cleaning the floor, it is placed in the base station 200 and enters the self-cleaning mode. The drive motor 411 drives the scraper 32 to rotate backward through the transmission mechanism. When the trigger 4211 on the drive gear 421 touches the second position switch 45, the drive motor 411 stops rotating backward. At this time, the scraper 32 disengages from the roller brush 21 to avoid friction. At the same time, the linkage component 301 on the scraper 32 rotates upward, which links the roller brush cover 22, causing the roller brush cover 22 to rotate downward. The roller brush cover 22 contacts the bristles on the roller brush 21, and the bristles can clean the dirt on the roller brush cover 22 after the self-cleaning starts.

[0147] The cleaning device 100 provided in this embodiment mainly improves the scraping function of the scraper 32 and the lifespan of the roller brush 21. While ensuring the scraping performance of the scraper 32, in order to increase the lifespan of the roller brush 21, the scraper 32 is controlled to disengage from the roller brush 21 during the self-cleaning process to reduce the friction between the scraper 32 and the roller brush 21. Through the linkage between the scraping mechanism 30 and the roller brush cover 22, the cleaning function of the roller brush cover 22 can also be realized, thereby improving the lifespan of the roller brush 21. At the same time, the dirt on the roller brush cover 22 is also cleaned simultaneously, realizing the self-cleaning of the dirt on the roller brush cover 22, improving the lifespan of the roller brush 21 and the overall cleaning effect of the machine.

[0148] 3. The control method for cleaning equipment 100 is as follows:

[0149] Step A, working mode, including smart mode or powerful mode, allows users to choose whether or not to clean according to their own judgment;

[0150] Step B, self-cleaning mode; its function is for users to choose whether or not self-cleaning is needed based on their own judgment.

[0151] More detailed steps, step A, Smart Mode or Powerful Mode:

[0152] Step A-① Drive motor 411 to rotate forward, driving the entire scraping mechanism to rotate forward 30 degrees;

[0153] During the forward rotation of step A-②, the machine determines whether the first position switch 44 is closed. If it is closed, continue to step A-③; if it is not closed, drive motor 411 continues to run until it closes within the specified time t, then continue to step A-③. If it does not close, then jump directly to step A-⑦.

[0154] After the first position switch is closed in step A-③, the drive motor 411 will no longer run;

[0155] Step A-④ The roller brush motor drives the roller brush 21 to rotate and begin cleaning;

[0156] Step A-⑤: Set the continuous operation time.

[0157] Step A-⑥ determines whether the user has selected to stop the machine; if "yes", proceed to step A-⑦; if "no", return to the working mode selection.

[0158] Step A-⑦ Cleaning equipment 100 stops.

[0159] More detailed, step B, self-cleaning mode:

[0160] Step B-① Drive motor 411 to rotate forward, driving the entire structure to rotate in reverse;

[0161] During the reversal process of step B-②, the machine determines whether the second position switch is closed. If it is closed, continue to B-③; if it is not closed, drive motor 411 continues to run until it closes within the specified time t, then continue to B-③; if it does not close, then directly jump to A-⑦.

[0162] After the second position switch is closed in step B-③, the drive motor 411 will no longer run;

[0163] Step B-④ The roller brush motor drives the roller brush 21 to rotate forward and backward to start self-cleaning;

[0164] Step A-⑤: Set the continuous operation time.

[0165] Step A-⑥ determines whether the user has selected to stop the machine; if "yes", proceed to A-⑦; if "no", return to the working mode selection.

[0166] Step A-⑦ Cleaning equipment 100 stops.

[0167] It should be noted that the control method proposed in this embodiment is based on the automatic oscillating scraper function of the floor scrubber. In addition to being applied to this product, the control logic can also be applied to other product series that are based on the same principle.

[0168] In some embodiments, the control method of the cleaning device 100 further includes: the controller of the cleaning device 100 adjusts the scraping stroke of the scraping mechanism 30 according to the usage information of the roller brush 21, so that when the cleaning device 100 is in cleaning mode, the scraping mechanism 30 can always maintain an interference fit with the brush bristles.

[0169] In the above embodiment, by adjusting the scraping stroke of the scraping mechanism 30 according to the actual use of the roller brush 21, the scraping mechanism 30 can still maintain an interference fit with the brush bristles even when the cleaning equipment 100 is performing floor cleaning work, effectively ensuring the cleaning effect of the scraping mechanism 30 on the dirt on the roller brush 21.

[0170] Specifically, based on the usage information of the roller brush 21, the scraping stroke of the scraping mechanism 30 is adaptively increased.

[0171] In some embodiments, usage information includes the usage time of the roller brush 21 or the amount of wear on the bristles of the roller brush 21; adjusting the scraping stroke of the scraping mechanism 30 based on the usage information of the roller brush 21 specifically includes the following steps:

[0172] Step S101: Obtain the usage time of the roller brush 21 or the wear of the bristles of the roller brush 21;

[0173] Step S102: Adjust the scraping stroke of the scraping mechanism 30 according to the obtained usage time of the roller brush 21 or the wear of the brush bristles of the roller brush 21.

[0174] The adjustment amount of the scraping stroke of the scraping mechanism 30 is directly proportional to the usage time of the roller brush 21 or the wear of the bristles.

[0175] In the above embodiments, as the usage time of the roller brush 21 increases or the wear of the bristles increases, the scraping stroke of the scraping mechanism 30 is adaptively increased. This ensures that even if the bristles of the cleaning device 100 become shorter after long-term use, the scraping mechanism 30 can still maintain an interference fit with the roller brush 21 during normal cleaning operations. This effectively guarantees the scraping effect of the scraping mechanism 30 on the dirt on the roller brush 21. It effectively solves the problem that the gap between the scraping mechanism 30 and the roller brush 21 increases after long-term use, causing the scraping mechanism 30 to be unable to effectively scrape the dirt on the roller brush 21 and affecting the cleaning effect of the cleaning device 100.

[0176] Specifically, in step S102, the scraping stroke of the scraping mechanism 30 is adaptively increased according to the increase in the usage time of the roller brush 21 or the increase in the wear of the brush bristles. That is, the longer the usage time of the roller brush 21 or the greater the wear of the brush bristles, the greater the adjustment of the scraping stroke of the scraping mechanism 30, so as to ensure that the scraping mechanism 30 can always be in interference fit with the brush bristles when cleaning the roller brush 21.

[0177] Furthermore, the cleaning equipment 100 is equipped with a timing device for calculating the usage time of the roller brush 21. The controller of the cleaning equipment 100 can calculate the increase in the scraping stroke of the scraping mechanism 30 according to a set algorithm formula based on the usage time of the roller brush 21, and then calculate the rotation angle of the drive motor 411. For example, the scraping stroke of the scraping mechanism 30 is adjusted once a month.

[0178] Alternatively, the cleaning device 100 may be equipped with a bristle wear detection mechanism to detect the amount of bristle wear. The controller of the cleaning device 100 can calculate the increase in the scraping stroke of the scraping mechanism 30 based on the amount of bristle wear, and then calculate the rotation angle of the drive motor 411. For example, each time a set length of bristle wear is detected, the scraping stroke of the scraping mechanism 30 is increased by the set amount accordingly. Optionally, the bristle wear detection mechanism can be installed on the housing 10 of the floor brush 101, and the amount of bristle wear is analyzed and judged by detecting the distance between the brush and the bristles. The bristle wear detection mechanism can be a distance sensor, an ultrasonic sensor, an infrared sensor, etc.

[0179] It should be noted that in this embodiment, the increase in the scraping stroke of the scraping mechanism 30 can be adjusted by keeping the interference fit between the scraping mechanism 30 and the bristles constant, or by keeping the contact force between the scraping mechanism 30 and the bristles constant.

[0180] The cleaning device 100 provided in this embodiment can effectively scrape dirt in cooperation with the roller brush 21 during the cleaning process, depending on the cleaning status. During the self-cleaning process, the scraper 32 is controlled to disengage from the roller brush 21 by the drive motor 411, which reduces the friction between the scraper 32 and the roller brush 21, improves the service life of the roller brush 21, reduces the replacement frequency of the roller brush 21, and enhances the user experience. When the entire unit is placed in the base station 200 and receives the self-cleaning command, the drive motor 411 drives the scraper 32 to rotate to the avoidance position. The trigger 4211 can trigger the second position switch 45. When the cleaning device 100 receives the trigger signal from the second position switch 45, it controls the drive device 40 to stop driving the scraping mechanism 30 to rotate, so that the scraping mechanism 30 is kept in the avoidance position. At this time, the scraping mechanism 30 is disengaged from the roller brush 21 to avoid friction. At the same time, the linkage component 301 on the scraping mechanism 30 rotates upward, which links the roller brush cover 22, so that the roller brush cover body 221 rotates downward to the self-cleaning position where it contacts the bristles on the roller brush 21. At this time, there is a slight interference between the roller brush cover body 221 and the bristles. Then, the roller brush 21 is controlled to rotate in both directions, and the bristles on the roller brush 21 can achieve self-cleaning of the dirt on the roller brush cover 22, improving the overall cleaning effect of the unit.

[0181] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
