[0030] In the following description, numerous specific details are presented to provide a more thorough understanding of the technical solutions provided by the embodiments of the present disclosure. However, it will be apparent to those skilled in the art that the technical solutions provided by the embodiments of the present disclosure may be implemented without one or more of these details.

[0031] It should be noted that the terms used herein are merely used to describe particular embodiments and are not intended to limit the exemplary embodiments of the present disclosure. As used herein, the singular form "a," "an," or "an" is intended to include the plural form unless the context clearly dictates otherwise. It should be further understood that the terms "comprise" and / or "include" as used herein specify the presence of features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0032]

[0023] Next, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be embodied in various different forms and should not be construed as being limited to only the embodiments set forth herein. It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.

[0033] As shown in FIGS. 1 to 13, an embodiment of the present disclosure provides a filtering device, a base station, and a cleaning robot system, where, as shown in FIG. 1, the cleaning robot system includes a cleaning robot 10 and a base station, i.e., the base station is used in cooperation with the cleaning robot 10, and the base station includes a filtering device.

[0034] 2 and 3 , the cleaning robot 10 includes a main body 110, a detection system 120, a control module 130, a drive system 140, a cleaning system 150, an energy system 160, and a human-machine interaction system 170. It should be understood that the cleaning robot 10 may be a self-mobile cleaning robot 10 or any other cleaning robot 10 that meets the requirements. The self-mobile cleaning robot 10 is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation. Here, when the self-mobile cleaning robot 10 starts working, the automatic cleaning device departs from the base station to perform the cleaning task. When the self-mobile cleaning robot 10 completes the cleaning task or needs to abort another cleaning task, the self-mobile cleaning robot 10 can return to the base station for charging or other operations.

[0035] As shown in FIG. 2, device body 110 includes a front portion 111 and a rear portion 112 and has a generally circular shape (both front and rear are circular), but may have other shapes, including, but not limited to, a generally D-shape with a square front portion and a circular rear portion, and a rectangular or square shape with a square front portion and a square rear portion.

[0036] 2, the detection system 120 includes a positioning device 121 located on the device body 110, a collision sensor and a proximity sensor provided on a buffer 122 of the front portion 111 of the device body 110, a cliff sensor provided at the bottom of the device body 110, and sensing devices such as a magnetometer, an accelerometer, a gyroscope, and an odometry provided inside the device body 110, and is used to provide various position information and movement status information of the device to the control module 130. The positioning device 121 includes, but is not limited to, a camera and a laser distance sensor (LDS).

[0037] As shown in FIG. 2, the front part 111 of the equipment body 110 may carry a buffer 122. During the cleaning process, when the drive wheel module 141 propels the cleaning robot 10 to run on the floor surface, the buffer 122 detects one or more events in the running path of the cleaning robot 10 through a sensor system, such as an infrared sensor, provided thereon. The cleaning robot 10 can control the drive wheel module 141 to respond to the event, such as an obstacle or a wall, detected by the buffer 122, such that the cleaning robot 10 moves away from the obstacle.

[0038] The control module 130 is provided on a main circuit board within the device body 110 and includes a computing processor, such as a central processing unit and an application processor, that communicates with a non-transitory memory, such as a hard disk, flash memory, or random access memory. The application processor uses a positioning algorithm, such as simultaneous localization and mapping (SLAM), to draw an instantaneous map of the environment in which the cleaning robot 10 is located, based on obstacle information fed back by the laser distance sensor. Furthermore, based on the distance information and speed information fed back by sensing devices such as sensors installed in the buffer 122, cliff sensors, magnetometers, accelerometers, gyroscopes, and odometry, the cleaning robot 10 comprehensively determines the current working state, location, and current posture of the cleaning robot 10, such as whether it has crossed a door stop, stepped on a carpet, is at a cliff and stuck above or below, the dust box is full, or has been picked up, and provides specific next operation strategies for different situations so that the cleaning robot 10 can have better cleaning performance and user experience.

[0039] As shown in FIG. 3 , the drive system 140 can operate the equipment body 110 to move across a floor surface based on a drive command having distance and angle information (e.g., x, y, and θ components). The drive system 140 includes a drive wheel module 141, which can simultaneously control the left and right wheels. To more precisely control the movement of the equipment, the drive wheel module 141 may include a left drive wheel module 141 and a right drive wheel module 141, respectively. The left and right drive wheel modules 141 are arranged along a lateral axis defined by the equipment body 110. To enable the cleaning robot 10 to move more stably across a floor surface or to have higher mobility, the cleaning robot 10 may include one or more driven wheels 142, which may include, but are not limited to, swivel wheels. The drive wheel module 141 includes a running wheel, a drive motor, and a control circuit for controlling the drive motor. A circuit for measuring drive current and an odometry may be further connected to the drive wheel module 141. The drive wheels may include a biased drop suspension system, and are movably fixed, for example, rotatably assembled to the main body 110, and are spring-biased to urge them downwardly away from the main body 110. The spring bias allows the drive wheels to maintain contact and traction with the floor surface with a constant ground contact force, while the cleaning elements of the cleaning robot 10 also contact the floor surface with a constant pressure.

[0040] The energy system 160 includes a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit, which are further connected to a single-chip microcomputer control circuit. The host connects the charging pole to a charging pole via charging electrodes located on the side or bottom of the device body.

[0041] The man-machine interaction system 170 may include buttons on a host panel for the user to select functions, a display screen, and / or indicator lights and / or a speaker, which are used to display the current device status or function options to the user, and may further include a mobile phone client program. For a route navigation type automatic cleaning device, the mobile phone client can display a map of the device's environment and the device's location to the user, providing the user with a richer and more user-friendly range of functions.

[0042] The cleaning system 150 may be a dry cleaning system 151 and / or a wet cleaning system 153 .

[0043] As shown in Figure 3, the dry cleaning system 151 provided by the embodiment of the present disclosure may include a roller brush, a dust box, a fan, and an air outlet. The roller brush, which has a certain degree of interference with the floor surface, picks up dust on the floor surface and lifts it up in front of the dust suction port between the roller brush and the dust box. The dust is then sucked into the dust box by suction gas generated by the fan and passing through the dust box. The dry cleaning system 151 may further include a side brush 152 with a rotating shaft, which forms a certain angle with the floor surface and moves the chips to the roller brush area of ​​the cleaning system 150.

[0044] 3 and 4, the wet cleaning system 153 provided by the embodiment of the present disclosure may include a cleaning head 1531, a driving unit 1532, a water supply mechanism, a liquid storage tank, etc. Here, the cleaning head 1531 may be disposed below the liquid storage tank, and the cleaning liquid inside the liquid storage tank is delivered to the cleaning head 1531 via the water supply mechanism, so that the cleaning head 1531 performs wet cleaning on the surface to be cleaned. In other embodiments of the present disclosure, the cleaning liquid inside the liquid storage tank may also be sprayed directly onto the surface to be cleaned, and the cleaning head 1531 cleans the surface by evenly applying the cleaning liquid.

[0045] Here, the cleaning head 1531 is used to clean a surface to be cleaned, and the drive unit 1532 drives the cleaning head 1531 to move substantially back and forth along a target surface, which is a part of the surface to be cleaned. The cleaning head 1531 moves back and forth along the surface to be cleaned, and a cleaning cloth or cleaning plate is provided on the surface of the cleaning head 1531 that comes into contact with the surface to be cleaned, and the back and forth movement generates high-frequency friction with the surface to be cleaned, thereby removing dirt on the surface to be cleaned.

[0046] In an embodiment of the present disclosure, as shown in FIG. 4 , the drive unit 1532 may further include a drive platform 1533 and a support platform 1534, where the drive platform 1533 is connected to the bottom surface of the equipment body 110 to provide driving force, and the support platform 1534 is detachably connected to the drive platform 1533 and is used to support the cleaning head 1531, which can move up and down by driving the drive platform 1533.

[0047] As an optional embodiment of the present disclosure, the wet cleaning system 153 may be connected to the appliance body 110 via an active lifting module. When the wet cleaning system 153 is temporarily not involved in work, for example, when the cleaning robot 10 stops at the base station to wash the cleaning head 1531 of the wet cleaning system 153 and inject water into the liquid storage tank of the wet cleaning system 153, or when the cleaning robot 10 encounters a surface to be cleaned that cannot be cleaned by the wet cleaning system 153, the wet cleaning system 153 is lifted by the active lifting module.

[0048] In the wet cleaning system 153 provided by the embodiment of the present disclosure, the cleaning head 1531, the drive platform 1533, the support platform 1534, the water delivery mechanism, the liquid storage tank, etc. may be powered by one or more motors. An energy system 160 provides power and energy to the motors and is controlled as a whole by the control module 130.

[0049] Here, the water supply mechanism in the embodiment of the present disclosure may include a water discharge device, which may be directly or indirectly connected to the liquid outlet of the liquid storage tank, whereby cleaning liquid flows toward the water discharge device through the cleaning liquid outlet of the liquid storage tank and is uniformly applied to the surface to be cleaned by the water discharge device. A connecting member may be provided on the water discharge device, and the water discharge device may be connected to the cleaning liquid outlet of the liquid storage tank via the connecting member. A distribution port may be provided on the water discharge device, and the distribution port may be a continuous opening or may be formed by combining multiple intermittent small openings, or the distribution port may be provided with multiple nozzles. The cleaning liquid flows toward the distribution port via the cleaning liquid outlet of the liquid storage tank and the connecting member of the water discharge device, and is uniformly applied to the surface to be cleaned through the distribution port.

[0050] In an embodiment of the present disclosure, the liquid storage tank may further include a water refill port, which may be located on a side wall of the water tank, and when the cleaning robot 10 stops at the base station, the base station may inject water into the liquid storage tank of the cleaning robot 10 through the water refill port.

[0051] 5 and 7, the base station 20 includes a base station body 21 and a cleaning assembly 30. The cleaning assembly 30 is movably mounted on the base station body 21. Specifically, the cleaning assembly 30 can move relative to the base station body 21 along a certain direction. For example, the cleaning assembly 30 can move back and forth along the left-right direction of the base station 20, which is indicated by the solid arrow in the figures. Here, the cleaning assembly 30 includes a cleaning member, which is used to remove impurities on the cleaning system 150 by interacting with the cleaning system 150. That is, when the cleaning robot 10 stops at the base station body 21, the cleaning assembly 30 is positioned opposite the cleaning system 150, and the cleaning member interferes with the cleaning system 150 to remove impurities on the cleaning system 150 as the cleaning assembly 30 moves relative to the base station body 21. That is, the cleaning robot 10 can realize automatic cleaning on the cleaning assembly 30 of the base station 20, thereby eliminating the need for manual cleaning of the cleaning system 150 or replacing it with a new cleaning system 150, simplifying manual operation, improving the manual cleaning experience, and being suitable for application deployment.

[0052] Furthermore, as shown in FIG. 7 , the cleaning assembly 30 further includes a liquid dispensing device 34. When the cleaning assembly 30 is cleaning the cleaning system 150 of the cleaning robot 10, the liquid dispensing device 34 of the cleaning assembly 30 works simultaneously to spray cleaning liquid onto the cleaning system 150 and use the collision force of the cleaning liquid to clean the cleaning system 150 or to allow the cleaning liquid to penetrate into the cleaning system 150, thereby further improving the cleaning effect when the cleaning member cleans the cleaning system 150.

[0053] Furthermore, the liquid discharger 34 sprays the cleaning liquid onto the cleaning member 33, which then applies the cleaning liquid to the cleaning system 150, thereby further ensuring a good cleaning effect. Specifically, the cleaning assembly 30 includes a bracket 32, which may include a first cleaning member 31 and a second cleaning member 33 mounted on the bracket 32. The first cleaning member 31 may be a cleaning scraper or the like, and the second cleaning member 33 may be a cleaning roller or the like, which may be rotatable. Furthermore, the liquid discharger 34 may spray the cleaning liquid onto the cleaning roller, which then rotates to uniformly apply the cleaning liquid to the cleaning system 150. It should be understood that the liquid discharger 34 may simultaneously spray the cleaning liquid onto the cleaning system 150 and the second cleaning member 33, to further improve the penetration efficiency of the cleaning system 150. 5 , the base station body 21 is provided with a cleaning tub 22. Specifically, the cleaning tub 22 is provided below the base station body 21, and the cleaning assembly 30 is disposed above the cleaning tub 22. This allows impurities removed from the cleaning system 150 by the cleaning member to be stored in the cleaning tub 22, facilitating subsequent disposal of the impurities and improving the cleanliness of the environment around the base station 20. It should be understood that the impurities removed from the cleaning system 150 may include dirty water, hair, scraps, particle dust, or other impurities that meet requirements, and are not particularly limited in the embodiments of the present disclosure. It should be understood that, since the cleaning assembly 30 is disposed above the cleaning tub 22, the cleaning liquid ejected from the liquid ejection device 34 can be stored in the cleaning tub 22 after cleaning the cleaning system 150.

[0054] 12, the base station 20 further includes a filter 40, which is installed in the cleaning tank 22 and is used to filter the liquid discharged from the cleaning tank 22. Because the liquid in the cleaning tank 22 contains solid impurities, i.e., the liquid in the cleaning tank 22 has a low cleanliness, directly discharging the liquid through the dirt discharge pipe may result in a risk of clogging the dirt discharge pipe. Therefore, by installing the filter 40 in the cleaning tank 22, the liquid discharged from the cleaning tank 22 to the external environment is filtered by the filter 40 to improve its cleanliness before being discharged through the dirt discharge pipe to the external environment, thereby reducing the risk of clogging the dirt discharge pipe and improving the smoothness and efficiency of dirt discharge from the cleaning tank 22. Here, the filter 40 is detachably attached to the cleaning tank 22 and can be removed from the cleaning tank 22 for easy cleaning and maintenance, which is convenient and beneficial to improving the user's cleaning and maintenance experience.

[0055] In the embodiment provided by the present disclosure, as shown in Figures 8 to 12, the filtering device 40 is provided with a float assembly 41, which has a float body 411 that floats on the liquid surface under the action of the liquid, and the base station 20 further includes a non-contact sensing element or a non-contact sensed element. Here, the non-contact sensing element is used to detect the non-contact sensed element, for example, the non-contact sensing element is used to detect the signal parameters transmitted from the non-contact sensed element, and one of the non-contact sensing element and the non-contact sensed element is mounted on the float body 411, and the other is mounted on the base station body 21, that is, one of the non-contact sensing element and the non-contact sensed element moves with the floating of the float body 411, and the other is mounted at a fixed position on the base station body 21, for example, the other is mounted at the mounting position of the filtering device 40 on the base station body 21, so that when the float body 411 floats up and down under the action of the liquid, the signal parameters transmitted from the non-contact sensed element detected by the non-contact sensing element are different, and further, the liquid level range in the cleaning tank 22 can be determined based on the different signal parameters, and whether the filtering device 40 is placed in the cleaning tank can be determined.

[0056] Furthermore, the filtering device 40 is installed in the cleaning basin 22, and when the liquid level in the cleaning basin 22 is within a certain range, the non-contact sensing element can sense the non-contact sensed element, which means that the filtering device 40 is accurately installed in the base station body 21, and the water level in the cleaning basin 22 is within a certain range, for example, the water level in the cleaning basin 22 is at a safe level, without affecting the normal operation of the base station. That is, the detection device composed of the float assembly 41, the non-contact sensing element, and the non-contact sensed element can simultaneously detect the liquid level in the cleaning basin 22 and the current position of the filtering device 40, thereby expanding the function of the float assembly 41 and simplifying the setting of the detection device, that is, simplifying the product structure, simplifying the system software program and algorithm, effectively saving costs, and being suitable for application deployment.

[0057] That is, the base station 20 provided in the embodiment of the present disclosure has a float assembly 41 on the filtering device 40, and by cooperating with a non-contact sensing element and a non-contact sensed element, the base station 20 can simultaneously detect whether the filtering device 40 is attached to the cleaning tank 22 and whether the water level in the cleaning tank 22 is within the normal range, thereby simplifying the structure of the base station 20.

[0058] Furthermore, since the float assembly 41 is provided on one side of the filter device 40, good detection between the non-contact sensing element and the non-contact sensed element can be achieved, which contributes to improving the detection accuracy.

[0059] Specifically, on the one hand, the non-contact sensed element is provided on the float body 411, and the non-contact sensing element is provided on the base station body 21; on the other hand, the non-contact sensing element is provided on the float body 411, and the non-contact sensed element is provided on the base station body 21. Different installation positions of the non-contact sensed element and the non-contact sensing element can meet the different structural and performance requirements of the non-contact sensed element and the non-contact sensing element, and can expand the use range of the product.

[0060] It should be understood that the non-contact sensed element may include a magnetic material, a light-emitting material, or other material that meets the requirements, and the non-contact sensing element may include a magnetic sensing material, a light-sensing material, or other material that meets the requirements. The non-contact sensed element or non-contact sensing element provided on the float body 411 may be located inside or outside the float body 411, or at any other position that meets the requirements, and is not particularly limited in the embodiments of the present disclosure.

[0061] In the above embodiment, the filter device 40 is detachably installed in the cleaning tank 22, so that the filter device 40 can be removed from the cleaning tank 22 for cleaning, maintenance or replacement, which is simple and convenient to operate.

[0062] As shown in FIG. 12, the filter 40 may be located at the bottom of the cleaning tank 22, which can easily improve the thoroughness with which the filter 40 filters the liquid in the cleaning tank 22.

[0063] The filter 40 is arranged on at least one side of the cleaning tank 22, that is, the filter 40 is arranged only on the bottom of one side of the cleaning tank 22, or the filter 40 can be installed on the bottom of both sides of the cleaning tank 22. Different installation positions of the filter 40 can meet the requirements of different structures of the filter 40 and different filtering efficiency of the cleaning tank 22, and can expand the scope of use of the product.

[0064] In the above embodiment, the high water level value of the cleaning tank 22 is the first preset threshold, and the specific range is below the first preset threshold, that is, when the liquid surface in the cleaning tank 22 is below the high water level value of the cleaning tank 22 and the filtering device 40 is installed in the cleaning tank 22, the non-contact sensing element can sense the non-contact sensed element, which means that the filtering device 40 is installed in the cleaning tank 22 of the base station body 21, the water level in the cleaning tank 22 is below the high water level value, and the liquid in the cleaning tank 22 does not affect the normal operation of the base station 20, for example, there is no risk of the dirty water in the cleaning tank 22 overflowing, and the dirty water in the cleaning tank 22 will not contaminate the cleaning assembly 30, etc., and at this time, the cleaning tank 22 can continue to contain impurities and dirty water.

[0065] Conversely, if the filtering device 40 is not installed in the cleaning tank 22 of the base station main body 21, or if the filtering device 40 is installed in the cleaning tank 22 of the base station main body 21 and the water level in the cleaning tank 22 is higher than a certain range, the non-contact sensing element will not be able to sense the non-contact sensed element, which means that the filtering device 40 is not installed in the designated position or the water level in the cleaning tank 22 is high, which may affect the normal operation of the base station 20. In this case, the user is prompted to install the filtering device 40 in the base station main body 21 or stop putting impurities and wastewater into the cleaning tank 22.

[0066] In the embodiment provided by the present disclosure, the high water level value of the cleaning tank 22 may be a fixed value, that is, the first preset threshold may be a fixed value, for example, the high water level value of the cleaning tank 22 may be 10 mm, 20 mm, 30 mm, 50 mm, or other values ​​that meet the requirements. Alternatively, the high water level value of the cleaning tank 22 may be related to the tank height of the cleaning tank 22, for example, the high water level value of the cleaning tank 22 may be 0.95 times, 0.90 times, 0.85 times the tank height of the cleaning tank 22, or other values ​​that meet the requirements.

[0067] In the above embodiment, the base station 20 further includes a controller, and the cleaning assembly 30 further includes a liquid dispensing device 34 electrically connected to the controller. When the cleaning members of the cleaning assembly 30 clean the cleaning system 150 of the cleaning robot 10, the liquid dispensing device 34 of the cleaning assembly 30 can operate simultaneously. The liquid dispensing device 34 sprays cleaning liquid onto the cleaning system 150, and the collision force of the cleaning liquid cleans the cleaning system 150 or allows the cleaning liquid to penetrate into the cleaning system 150, thereby further improving the cleaning effect when the cleaning members clean the cleaning system 150. Here, because the cleaning assembly 30 is located above the cleaning tub 22, the cleaning liquid is collected in the cleaning tub 22 after cleaning the cleaning system 150.

[0068] The non-contact sensing element is electrically connected to the controller of the base station 20 and outputs the sensing result to the controller. It should be understood that the controller of the base station 20 can exchange information with the cleaning robot 10 or a remote control terminal (APP). This allows the controller to rationally control the operation of other components of the cleaning system 150 according to the sensing result of the non-contact sensing element, for example, controlling the operating state of the liquid dispensing device 34 according to the sensing result. For example, when the non-contact sensing element senses the non-contact sensed element, the non-contact sensing element controls the liquid dispensing device 34 to continue operating, and when the non-contact sensing element does not sense the non-contact sensed element, the non-contact sensing element controls the liquid dispensing device 34 to stop operating, thereby preventing the liquid in the cleaning basin 22 from affecting the normal operation of the base station 20. At the same time, when the non-contact sensing element does not sense the non-contact sensed element, the controller can also issue a warning signal to remind the user to check whether the filter device 40 is installed in the specified position. This installation greatly improves the reliability and safety of the operation of the base station 20 and is suitable for application deployment.

[0069] Furthermore, as shown in FIG. 5, the base station 20 further includes a liquid supply unit 50 and a liquid delivery path, one end of which is connected to the liquid supply unit 50 and the other end of which is connected to the liquid ejection device 34, so that the liquid supply unit 50 delivers cleaning liquid to the liquid ejection device 34 through the liquid delivery path.

[0070] In some possible embodiments provided by the present disclosure, the non-contact sensed element is provided on the float body 411 and the non-contact sensing element is provided on the base station body 21 .

[0071] Furthermore, the non-contact sensed element includes a magnetic member, and the non-contact sensing element includes a magnetic sensing element, such as a Hall sensor. Here, the magnetic member is provided on the float body 411, and the magnetic sensing element is provided on the base station body 21. Specifically, the magnetic member may be provided inside the float body 411. This avoids the problem of the magnetic member being wetted and corroded by liquid when provided outside the float body 411, causing malfunctions and hindering signal transmission strength, and further contributes to improving the service life of the magnetic member and the stability and reliability of the transmitted signal.

[0072] That is, in the base station 20 provided by the embodiment of the present disclosure, the float assembly 41 is installed on the filtering device 40, the filtering device 40 is installed in the cleaning tank 22 of the base station 20, the magnetic member is installed inside the float body 411, and the magnetic sensing element is installed on the base station body 21. Under the action of liquid, when the magnetic member floats within the detection range of the magnetic sensing element, that is, when the magnetic sensing element can detect the signal of the magnetic member, it means that the filtering device 40 is installed in the cleaning tank 22 and the liquid surface in the cleaning tank 22 is within a certain range, for example, the liquid surface is below the high water level of the cleaning tank 22. At this time, the control device controls the liquid discharge device 34 to continue working and the cleaning assembly 30 to continue working to clean the cleaning system 150 of the cleaning robot 10. If the magnetic member floats out of the detection range of the magnetic sensing element, i.e., if the magnetic sensing element can no longer detect the signal from the magnetic member, the liquid level in the cleaning tank 22 may reach or exceed the high water level of the cleaning tank 22, which may affect the normal operation of the base station 20, or the filter 40 may not be installed correctly in the cleaning tank 22. In this case, the control device will control the base station 20 to stop operation, for example, the liquid dispensing device 34 to stop operation, to prevent the liquid level in the cleaning tank 22 from continuing to rise and overflowing from the cleaning tank 22. At the same time, the control device may send a warning signal to prompt the user to check whether the filter 40 is installed in the specified position. This type of installation is simple in structure, easy to implement, low in cost, and suitable for application deployment.

[0073] Specifically, the magnetic member may be a magnetic strip, a magnetic ring, or other magnetic structure that meets the requirements, the magnetic sensing element may be a magnetic sensing sensor or other structure that meets the requirements, and specifically, the magnetic sensing sensor may be a ring structure, a sheet-like structure, or other structure that meets the requirements.

[0074] Furthermore, the number of magnetic sensing elements can be one, two or more, and two or more magnetic sensing elements can be arranged at different positions on the base station body 21, which can sense that the liquid surface at different heights in the cleaning tank 22 reaches different specific ranges, that is, the liquid surface at different heights in the cleaning tank 22 can be detected, thereby expanding the use range of the product.

[0075] In some feasible embodiments provided by the present disclosure, as shown in Figures 8, 10 and 11, the filtration device 40 may include a filtration screen 42 and a housing 43, where the filtration screen 42 is arranged above the housing 43 and forms a storage chamber together with the housing 43, where filtration holes 423 are provided on the filtration screen 42, and the filtration screen 42 is used to filter some impurities carried by the liquid flowing into the storage chamber through the cleaning tank 22, and the storage chamber is used to store some solid impurities carried by the liquid in the storage chamber.

[0076] Specifically, after some impurities have been filtered out of the wastewater in the cleaning tank 22 by the filter holes 423 of the filter screen 42, it flows into the storage chamber. For example, the filter screen 42 filters out large particles of solid impurities, hair, etc. in the cleaning tank 22 onto the filter screen 42, and the wastewater and small particles of solid impurities flow into the storage chamber, contributing to improving the cleanliness of the liquid in the storage chamber. At least some of the solid impurities, such as mud and sand, carried by the wastewater in the storage chamber are settled at the bottom of the storage chamber, and the remaining impurities are discharged through the storage chamber to the external environment together with the liquid, improving the smoothness of liquid discharge, reducing the risk of clogging the dirt discharge pipeline, and further contributing to improving the dirt discharge efficiency.

[0077] Furthermore, the bottom of the cleaning tank 22 is angled downward from the side farther from the filter device 40 to the side closer to the filter device 40, which provides good guidance and helps the liquid in the cleaning tank 22 flow quickly and thoroughly through the filter device 40, thereby improving filtering efficiency and effectiveness.

[0078] That is, in the base station 20 provided by the embodiment of the present disclosure, a filter device 40 is installed in the cleaning tank 22, so that the wastewater in the cleaning tank 22 can filter out large-particle solid impurities in the cleaning tank 22 through the filter screen 42 of the filter device 40, and solid impurities such as mud and sand in the filtered liquid will settle to the bottom of the storage chamber, and the dirt discharge operation will be performed on the relatively clean liquid in the storage chamber, thereby achieving the discharge of wastewater in the cleaning tank 22, which reduces the risk of clogging the dirt discharge pipeline and contributes to improving the dirt discharge efficiency.

[0079] During the dirt discharge process, large solid impurities are filtered out of the storage chamber. For example, after the liquid in the cleaning tank 22 is emptied, the large solid impurities remain on the filter screen 42, while solid impurities such as mud and sand remain at the bottom of the storage chamber. This facilitates the separation of the large solid impurities from the solid impurities such as mud and sand in the storage chamber, and contributes to improving the cleaning experience of the filter device 40. The size and shape of the filter holes 423 can be reasonably set to limit the filtering accuracy of the filter screen 42. Specifically, the minimum opening size of the filter holes 423 can be 8 mm, 10 mm, 15 mm, or any other value that meets the requirements, and is not particularly limited in the embodiments of the present disclosure.

[0080] In the above embodiment, the float assembly 41 is provided outside the accommodating chamber, which prevents the accommodating chamber from interfering with the floating range of the float assembly 41, thereby further improving the detection accuracy of the float assembly 41.

[0081] 8 and 10, in some possible embodiments provided by the present disclosure, a barrier 48 is further provided on the filter screen 42, and the barrier 48 is connected to a portion of the outer edge of the filter screen 42 to form an installation space that communicates with the receiving chamber, and the float body 411 is horizontally disposed within the installation space, i.e., the float body 411 communicates with the receiving chamber, thereby contributing to improving the accuracy of the float assembly 41 detecting the liquid level in the cleaning tank 22. Filter holes 423 are provided on the filter screen 42 outside the installation space. During the dirt discharge process, large particles of impurities may remain on the filter screen 42 through the filter holes 423. The provision of the barrier 48 can protect the float body 411 to a certain extent, preventing large particles of dirt on the filter screen 42 from affecting the floating accuracy of the float body 411, thereby further improving the detection accuracy of the float assembly 41.

[0082] 8, 10 and 11, the float assembly 41 includes a mounting bracket 412 and a connecting member 413, where the mounting bracket 412 is mounted on the filtering screen 42, and the connecting member 413 connects the mounting bracket 412 to one end of the float body 411, and the float body 411 is rotatable relative to the mounting bracket 412. That is, the float body 411 floats on the liquid surface under the action of the liquid, and the float body 411 can swing substantially up and down relative to the mounting bracket 412, that is, the float body 411 can swing toward the housing 43 relative to the mounting bracket 412 and away from the housing 43, and the non-contact sensing element provided on the float assembly 41 is driven to swing up and down relative to the housing 43, and in cooperation with the non-contact sensing element provided on the base station body 21, it is possible to detect the liquid level in the cleaning tank 22 and whether the filtering device 40 is installed in the cleaning tank 22.

[0083] Specifically, a through hole is provided in the mounting bracket 412, a mounting hole is provided at one end of the float body 411, a connecting member 413 is inserted through the mounting hole and the through hole, and one end of the float body 411 is rotatably connected to the mounting bracket 412, where the connecting member 413 may be a rotating shaft, an anchor, or other connecting member 413 that meets the requirements, and the axis of rotation of the float body 411 relative to the mounting bracket 412 is parallel to the plane on which the bottom wall of the cleaning tank 22 is located, for example, the axis of the rotating shaft is parallel to the plane on which the bottom wall of the cleaning tank 22 is located, so that the float assembly 41 can swing only substantially vertically relative to the mounting bracket 412 to achieve accurate measurement of the liquid level.

[0084] Furthermore, in the embodiment of the present disclosure, the mounting bracket 412 may be detachably provided on the filtration screen 42, i.e., the mounting bracket 412 allows the float assembly 41 to be quickly and conveniently attached to the filtration device 40, and the float assembly 41 can be configured as a standardized module for corresponding products or scenarios, thereby expanding the range of use of the float assembly 41. At the same time, the installation of the mounting bracket 412 allows the user to detach the float assembly 41 from the filtration screen 42 of the filtration device 40 for easy maintenance and cleaning, greatly improving the user experience.

[0085] In another embodiment of the present disclosure, the mounting bracket 412 is formed on the filter screen 42, i.e., the mounting bracket 412 and the filter screen 42 are an integrated structure, which is convenient for production, simplifies the assembly operation of the mounting bracket 412 and the filter screen 42, improves production efficiency, contributes to cost reduction, and improves the reliability of the connection between the mounting bracket 412 and the filter screen 42.

[0086] In the above embodiment, the mounting bracket 412 is provided within the mounting space, for example, the mounting bracket 412 may be removably provided on the fence 48 or formed on the fence 48, or the mounting bracket 412 may be removably provided on a portion of the outer edge of the filter screen 42 or formed on a portion of the outer edge of the filter screen 42.

[0087] The float assembly 41 may be integrally formed with the filter screen 42, which further improves production efficiency and reduces manufacturing costs. For example, the filter screen 42 and the float assembly 41 may be integrally molded, with the magnetic member provided outside the float assembly 41. Alternatively, the filter screen 42 and the float assembly 41 may both be injection-molded parts, with the magnetic member provided inside the float assembly 41 and integrally molded with the filter screen 42 during the injection molding process, further simplifying the assembly process.

[0088] 8 and 9, the filtering device 40 has a water outlet 44 that connects the storage chamber with the external environment, and the water outlet 44 is provided on at least one side of the filtering device 40. That is, the liquid in the storage chamber is discharged through the water outlet 44, thereby discharging the dirt from the cleaning tank 22.

[0089] Furthermore, as shown in FIG. 6, the cleaning tank 22 is provided with a dirt discharge outlet 211, which is connected to the external environment, and the water outlet 44 connects the dirt discharge outlet to the storage chamber, so that the wastewater in the cleaning tank 22 flows into the storage chamber through the filter screen 42 and is discharged to the external environment through the water outlet 44 and the dirt discharge outlet 211.

[0090] Furthermore, the base station 20 may further include a dirt discharge mechanism, which communicates with the dirt discharge port 211 and transports the dirty water in the storage chamber to the outside of the cleaning tank 22 through the water outlet 44 and the dirt discharge port 211 by suction action, pumping action, etc. of the dirt discharge mechanism, thereby further improving the dirt discharge effect of the base station 20. Specifically, the dirt discharge mechanism may include a fan assembly or a pump body assembly, or a dirt discharge assembly that meets the requirements, and is not particularly limited in the embodiments of the present disclosure.

[0091] In addition, the base station 20 may further include a collection box, which is connected to the dirt discharge outlet 211 via a dirt discharge mechanism, and the wastewater in the cleaning tank 22 is transported to the collection box via the storage chamber, the water outlet 44, the dirt discharge outlet 211, and the dirt discharge mechanism, so that the overflow of impurities in the cleaning tank 22 will not affect the cleaning effect of the cleaning element and will not pollute the working environment. The installation of the collection box ensures good cleaning effect and is advantageous for centralized treatment of the collected impurities.

[0092] It should be understood that the water outlet 44 may be directly connected to the dirt discharge mechanism, thereby simplifying the installation of the dirt discharge port 211 of the cleaning tank 22 and simultaneously realizing the discharge of dirty water within the cleaning tank 22. Specifically, the water outlet 44 is connected to the dirt discharge port 211 or the dirt discharge mechanism via a dirt discharge pipe.

[0093] In this embodiment, the water outlet 44 is higher than the bottom of the storage chamber, which promotes the settling of impurities while reducing the possibility that mud and sand accumulated at the bottom of the storage chamber will flow out of the water outlet 44 along with the water. This also reduces the risk of clogging the dirt discharge pipe, contributing to improved dirt discharge efficiency.

[0094] Here, the water outlet 44 may be installed on one side, both sides, or multiple sides of the filter 40. Different installation positions of the water outlet 44 can meet different requirements for dirt discharge efficiency while also meeting different structural requirements of the filter 40, thereby expanding the scope of use of the product.

[0095] In some feasible embodiments provided by the present disclosure, as shown in FIG. 11 , the filtration device 40 may further include a handle 45 provided on the filtration screen 42, the handle 45 being located outside the storage chamber, and the handle 45 allows the user to quickly install the filtration device 40 in the cleaning tank 22, or quickly remove the filtration device 40 installed in the cleaning tank 22 from the cleaning tank 22. That is, the installation of the handle 45 makes it convenient for the user to hold the filtration device 40 to install or remove the filtration device 40, and improves the user's operating experience.

[0096] In the above embodiment, on the one hand, the handle 45 is provided on the side of the filter screen 42 away from the housing 43, for example, the handle 45 is provided above the filter screen 42 and connected to the filter screen 42; specifically, to meet different structural requirements of the handle 45 and the filter screen 42, the handle 45 may be detachably connected to the filter screen 42, or connected via a connecting structure or adhesive. On the other hand, the handle 45 is formed on the filter screen 42, for example, the handle 45 is formed above the filter screen 42, that is, the handle 45 is an integral structure with the filter screen 42, which is convenient for processing and contributes to improving the reliability of the connection between the handle 45 and the filter screen 42.

[0097] 11 , the handle 45 has a protrusion 451 connected to the filter screen 42, and a stopper 452 is provided on the outer edge of the protrusion 451 at one end away from the filter screen 42. This allows the user to easily grip the handle 45. For example, the user can grip the protrusion 451 and prevent it from falling off via the stopper 452, thereby improving the convenience and reliability of the user's grip of the handle 45. Specifically, the protrusion 451 and the stopper 452 are integrally formed, which is convenient for processing. Furthermore, the projection of the protrusion structure 422 on the filter screen may be circular, elliptical, polygonal, or any other shape that meets the requirements, and is not particularly limited in the embodiments of the present disclosure.

[0098] In some embodiments provided by the present disclosure, on the one hand, the filtration screen 42 and the housing 43 have a detachable structure, whereby the filtration screen 42 and the housing 43 can be cleaned and maintained separately, improving the user's cleaning and maintenance experience; here, the filtration screen 42 and the housing 43 are arranged in a split structure, so that the user can easily clean impurities such as mud and sand accumulated in the housing 43 after opening the storage chamber.

[0099] On the other hand, the filter screen 42 and the housing 43 are of an integral structure, which is convenient for production, simplifies assembly operations, and contributes to improving production efficiency. It should be understood that when the filter screen 42 and the housing 43 are of an integral structure, the impact force of the liquid can be used to clean the mud and sand accumulated in the storage chamber. As for the large solid impurities remaining on the filter screen 42, they are located outside the storage chamber and can be directly cleaned.

[0100] Furthermore, a positioning structure is provided on one of the filtration screen 42 and the housing 43, and a positioning structure is provided on the other, and the filtration screen 42 and the housing 43 are detachably connected by matching the positioning structure with the positioning structure.

[0101] Specifically, the position restricting structure may include a groove, and the positioning structure may include a protrusion that fits into the groove, or the position restricting structure may include a magnetic member, and the positioning structure may further include a magnetic attraction member that matches the magnetic member. It should be understood that the position restricting structure and the positioning structure may be other structures that meet the requirements, and are not particularly limited in the embodiments of the present disclosure.

[0102] Furthermore, in the embodiment of the present disclosure, the filtering screen 42 and the housing 43 may be pivotally connected to open and close the chamber of the filtering device 40, thereby allowing the user to easily clean the impurities in the chamber. For example, the filtering screen 42 and the housing 43 may be connected via a pivot shaft.

[0103] In some possible embodiments provided by the present disclosure, as shown in Figures 12 and 13, an installation groove is provided on the bottom of the cleaning tank 22, and the filter screen 42 is adapted to be positioned in the installation groove, i.e., the receiving chamber is positioned in the installation groove. A first foolproof positioning member 241 and a second foolproof positioning member 242 are provided inside the cleaning tank 22 from top to bottom, i.e., the first foolproof positioning member 241 is positioned above the second foolproof positioning member 242. As shown in Figures 8 and 10, the filter device 40 is provided with a foolproof positioning member 46 and a supporting member 421. When the foolproof positioning member 46 matches the first foolproof positioning member 241, the supporting member 421 indicates that the filter device 40 is not installed in a predetermined position, and when the foolproof positioning member 46 matches the second foolproof positioning member 242, the supporting member 421 indicates that the filter device 40 is installed in a predetermined position.

[0104] Here, the indicator 421 has a good indicating effect, so that when the indicator 421 indicates that the filter device 40 is not installed in the predetermined position, the user can immediately adjust the installation position of the filter device 40 relative to the installation groove of the cleaning tub 22 and determine whether the filter device 40 is installed correctly in the appropriate position in the cleaning tub 22 according to the indication of the indicator 421. That is, the cooperation of the two foolproof positioning members 24, the foolproof position limiting member 46 and the indicator 421 can quickly and accurately determine whether the filter device 40 is installed correctly and accurately in the appropriate position in the cleaning tub 22, and prompt the user to perform the corresponding operation, resulting in a simple structure and convenient use.

[0105] That is, in the base station 20 provided in the embodiment of the present disclosure, two foolproof positioning members, namely a first foolproof positioning member 241 and a second foolproof positioning member 242, are provided on the base station body 21, and a foolproof position control member 46 and a supporting member 421 are provided on the filtering device 40, so that the filtering device 40 can filter the liquid discharged from the cleaning tank 22, detect the liquid level in the cleaning tank 22, and detect whether the filtering device 40 is installed at the predetermined position relative to the cleaning tank 22, and at the same time, indicate whether the filtering device 40 is installed at the predetermined position accurately relative to the cleaning tank 22, thereby expanding and diversifying the functions of the filtering device 40 and meeting the design requirements of the base station 20 with a compact structure.

[0106] Furthermore, other foolproof positioning members besides the first foolproof positioning member 241 and the second foolproof positioning member 242 may be provided on the base station body 21. That is, the number of foolproof positioning members is at least three, and for example, the number of foolproof positioning members may be three, four, or any other value that meets the requirements. A different number of foolproof positioning members can meet the requirements of different mounting positions of the filtration device 40 relative to the cleaning tank 22 and different structures of the filtration device 40. Note that in some embodiments, the number of foolproof positioning members may be one. That is, when the foolproof positioning member matches the foolproof position limiting member 46, the indicating member 421 indicates that the filtration device 40 is mounted in a predetermined position; otherwise, the indicating member 421 indicates that the filtration device 40 is not mounted in a predetermined position, which contributes to further simplifying the structure.

[0107] 13 , the first foolproof positioning member 241 and the second foolproof positioning member 242 are disposed above the mounting groove, for example, the first foolproof positioning member 241 and the second foolproof positioning member 242 are disposed on the inner wall of the cleaning tank 22, that is, the first foolproof positioning member 241 is disposed above the second foolproof positioning member 242. The support member 421 may have a planar structure disposed above the foolproof position limiting member 46, for example, the support member 421 is the top surface of the filter device. When a user installs the filter device 40, for example, when the user simply places the filter device 40 in the mounting groove without applying downward pressure to the filter device 40, the foolproof position limiting member 46 is abutted by the first foolproof positioning member 241. At this time, the indicator 421, i.e., the planar structure above the foolproof positioning member 46, is higher than the tank top 221 of the cleaning tank 22, indicating that the filter 40 is not installed in the correct position. That is, the side wall of the filter 40 closest to the inside of the cleaning tank 22 protrudes from the tank bottom of the cleaning tank 22. In this case, liquid at the bottom of the cleaning tank 22 outside the mounting groove may be blocked by the side wall and may not flow smoothly through the filter 40. For example, the liquid may not flow into the storage chamber through the filter screen 42, and therefore the filter 40 must be reinstalled. Because the indicator 421 clearly protrudes from the cleaning tank 22, it can notify the user that the filter 40 is not installed in the correct position. After receiving the indication, the user applies downward pressure to the filter 40, causing the foolproof positioning member 46 to move downward and align with the second foolproof positioning member 242. That is, the foolproof positioning member 46 is positioned under the second foolproof positioning member 242.At this time, the planar structure of the support member 421, i.e., the foolproof position control member 46, is located inside the cleaning tank 22, i.e., the planar structure is located below the tank top 221 of the cleaning tank 22 or is flush with the tank top 221, indicating that the filtration device 40 is installed in a predetermined position; at this time, the liquid located at the bottom of the cleaning tank 22 outside the installation groove can flow smoothly through the filtration device 40 to achieve filtration, i.e., the liquid can smoothly flow into the storage chamber through the filtration screen 42.

[0108] Here, the indicator member 421 is a planar structure located above the foolproof positioning member 46. The planar structure facilitates comparison of planarity with other members and allows users to check whether the filter device 40 is installed in the desired position. The planar structure is easy to process, implement, and adapt to various applications. Furthermore, the planar structure may be painted or equipped with an indicator light to further attract attention and facilitate identification. For example, the planar structure may be painted in yellow, red, or other bright colors, allowing users to quickly and accurately locate the position of the planar structure and determine whether it protrudes from the top 221 of the cleaning tub 22 to determine whether the filter device 40 is installed in the desired position.

[0109] That is, in the base station 20 provided by the embodiment of the present disclosure, an installation groove is provided at the bottom of the cleaning tank 22, and the positional relationship between the top surface of the filter 40 and the top 221 of the cleaning tank 22, for example, whether the top surface of the filter 40 protrudes from the cleaning tank 22, can be used to determine whether the filter 40 is installed accurately in the specified position relative to the cleaning tank 22. This can avoid a situation where the filter 40 and the cleaning tank 22 are not installed in the specified position and the non-contact sensing element senses the non-contact sensed element, improving the installation accuracy of the filter 40, which has a simple structure, is easy to implement, has good indication effect, and provides accurate indication results, allowing the user to easily confirm whether the filter 40 is installed in the specified position.

[0110] Here, by installing the first foolproof positioning member 241, the second foolproof positioning member 242 and the foolproof position control member 46, the movement of the filtration device 40 relative to the cleaning tank 22 can be restricted, for example, the filtration device 40 can be restricted from moving vertically upward relative to the cleaning tank 22, and further, it becomes easy to perform pre-positioning when installing the filtration device 40 and to securely connect the filtration device 40 to the base station main body 21, resulting in a simple structure and easy implementation.

[0111] In the embodiment of the present disclosure, the second foolproof positioning member 242 also serves to fix the filtration device 40 when the filtration device 40 is accurately installed in the installation groove. In addition, since the first foolproof positioning member 241 is located above the second foolproof positioning member 242, when the foolproof position limiting member 46 is pushed up by the first foolproof positioning member 241, it can more clearly indicate to the user that the filtration device 40 is not accurately installed in the cleaning tank 22, which contributes to improving the reliability of the operation of the base station 20.

[0112] In the above embodiment, as shown in Figures 8 and 10, the filtration device 40 includes a connection part 47 connected to the filtration screen 42 and extending above the mounting groove, and the foolproof positioning member 46 is mounted on the connection part 47, so that the foolproof positioning member 46 is located within the mounting groove, avoiding the problem that the gap between the filtration device 40 and the mounting groove is large, preventing some liquid from flowing through the filtration device 40 and affecting the filtration effect. In other words, the matching of the foolproof positioning member 46 located above the mounting groove with the second foolproof positioning member 242 contributes to improving the tightness of the connection between the filtration device 40 and the mounting groove, ensuring good filtration effect.

[0113] Here, one end of the connection part 47 is connected to the filtration screen 42, and a planar structure is provided at one end of the connection part 47 away from the filtration screen 42, i.e., the planar structure is located at the top of the connection part 47, so that the connection part 47 can realize the installation of the foolproof position control member 46 and the support member 421, and the structure is compact, and the base station has a small volume, which can meet the design requirements of a compact structure.

[0114] Furthermore, the connecting portion 47 is connected to the filtration screen 42, for example, the connecting portion 47 and the filtration screen 42 are integrally molded, which improves the connection reliability of the connecting portion 47 and the filtration screen 42, is convenient for production, simplifies the assembly process, and reduces manufacturing costs.

[0115] In the above embodiment, the foolproof positioning member 46 has a snap-fit ​​structure, and the first foolproof positioning member 241 and the second foolproof positioning member 242 are both elastic members, wherein the first foolproof positioning member 241 includes a first abutment portion 243 adapted to abut against the foolproof positioning member 46, and the second foolproof positioning member 242 includes a second abutment portion 245 adapted to abut against the foolproof positioning member 46, and the first abutment portion 243 is disposed above the second abutment portion 245, thereby allowing the foolproof positioning member 46 to abut against the first abutment portion 243 and the second abutment portion 245, thereby restricting the movement of the filtration device 40 relative to the base station body 21, and the elasticity of the first foolproof positioning member 241 and the second foolproof positioning member 242 can realize pre-positioning and detachable connection between the filtration device 40 and the base station body 21.

[0116] For example, during the assembly process of the filtration device 40, when the snap-fit ​​structure of the foolproof positioning member 46 abuts against the first abutment portion 243 of the first foolproof positioning member 241, the planar structure above the connection portion 47 of the filtration device 40 becomes higher than the tank top 221 of the cleaning tank 22, which means that the filtration device 40 is not installed in the specified position. Because the first foolproof positioning member 241 is an elastic member, it overcomes the elastic force acting on the foolproof positioning member 46 and continues to press the filter 40 downward, until the snap-fit ​​structure of the foolproof positioning member 46 abuts against the second abutment portion 245 of the second foolproof positioning member 242, and the planar structure above the connection portion 47 of the filter 40 is positioned within the cleaning tub 22, for example, so that the planar structure is flush with or lower than the top surface 221 of the cleaning tub 22. This means that the filter 40 is installed in a predetermined position. The elastic force of the second foolproof positioning member 242 acting on the foolproof positioning member 46 can reliably and stably restrict the filter 40 within the installation groove, thereby achieving a secure connection between the filter and the base station body 21.

[0117] 8 and 9, a groove structure is provided on the inner wall of the mounting groove, and a protrusion structure 422 that fits into the groove structure is provided on the outer wall of the filter device 40. The fit between the groove structure and the protrusion structure 422 allows the filter device 40 and the mounting groove to be pre-positioned when assembled, contributing to improving the assembly efficiency of both. It should be understood that the protrusion structure 422 may also be provided on the outer wall of the housing 43.

[0118] 13 , the first foolproof positioning member 241 further includes a first support portion 244 for connecting the first abutment portion 243 and the base station main body 21, which contributes to improving the reliability of the connection between the first abutment portion 243 and the base station main body 21. The second foolproof positioning member 242 further includes a second support portion 246 for connecting the second abutment portion 245 and the base station main body 21, which contributes to improving the reliability of the connection between the second abutment portion 245 and the base station main body 21. The first support portion 244 and the first abutting portion 243 may be of an integral or separate structure, and the second support portion 246 and the second abutting portion 245 may be of an integral or separate structure, i.e., the first foolproof positioning member 241 may be of an integral or separate structure, and the second foolproof positioning member 242 may be of an integral or separate structure, where an integral structure is convenient for production, simplifies the assembly process, and contributes to reducing manufacturing costs, and a separate structure is convenient for maintenance and reduces replacement costs. Furthermore, the first foolproof positioning member 241 and the second foolproof positioning member 242 may be of an integral structure with the base station main body 21, which is convenient for processing, simplifies the assembly process, and contributes to reducing manufacturing costs.

[0119] Here, the first support portion 244 and / or the second support portion 246 may be an elastic bending structure, i.e., due to elastic deformation of the bending structure, the first abutment portion 243 and / or the second abutment portion 245 can move relative to the base station main body 21, and further, the first abutment portion 243 and / or the second abutment portion 245 can be securely and closely abutted against the snap-fit ​​structure of the fool-proof position control member 46, or the snap-fit ​​structure can be smoothly released from the first abutment portion 243 and / or the second abutment portion 245, which has a simple structure, is easy to realize, and is low in cost.

[0120] Specifically, the bent structure may be at least one of L-shaped, Z-shaped, V-shaped, N-shaped, and M-shaped, and different shapes of the bent structure may meet different position and structural requirements of the first abutting portion 243 and / or the second abutting portion 245. Here, the first abutting portion 243 and / or the second abutting portion 245 may be a protrusion, a slot, or other structures that meet requirements, and are not particularly limited in the embodiments of the present disclosure.

[0121] Specifically, as shown in FIG. 13, a track groove 23 through which the cleaning assembly 30 passes is provided on the side wall of the mounting groove, and the first foolproof positioning member 241 and the second foolproof positioning member 242 are provided near one end of the track groove 23, thereby reducing the influence of the first foolproof positioning member 241 and the second foolproof positioning member 242 on the movement range of the cleaning assembly 30, greatly expanding the movement range of the cleaning assembly 30 and contributing to improving the cleaning effect.
