[0086] Cleaning devices such as sweeping robots can be used to clean the surface to be cleaned. After cleaning, the sweeping robots can be stored in a base station and charged using the base station. In related technologies, due to the relatively simple functions of base stations, the user usage rate of sweeping robots and base stations is relatively low.

[0087] The base station can be used to support the wet cleaner, and the wet cleaner can be used to clean the surface to be cleaned alone. The base station can also be used to dock the cleaning device, so as to increase the use scenarios of the base station, and improve the use rate of the base station, the wet cleaner and the cleaning device.

[0088] Please refer to Figure 1 、 Figure 2 and Figure 3 The base station 100 can be used in a robot system, and the robot system can include the base station 100 and the cleaning device 200.

[0103] See also Figure 3 In some examples, the base station 100 may further include a water washing tank 101. The water washing tank 101 may be a groove recessed in the base 10. When the cleaning device 200 is docked at a preset position on the base 10, the wet cleaning components of the cleaning device 200, such as a rag, may be at least partially located within the water washing tank 101. The cleaning device 200 may be cleaned by supplying water into the water washing tank 101. In some examples, the water washing tank 101 may also be used to receive wastewater generated when cleaning the wet cleaning components. When the cleaning device 200 is docked on the base 200, the wet cleaning components of the cleaning device 200 may be suspended above the water washing tank 101. The wet cleaning components may be cleaned by supplying or spraying water onto the wet cleaning components. The wastewater generated during cleaning may be collected in the water washing tank 101.

[0104] In some examples, when the cleaning device 200 is docked on the base 10 , the sewage holding tank 210 of the cleaning device 200 may be connected to the water washing tank 101 , so that water in the water washing tank 101 may be sucked into the sewage holding tank 210 .

[0105] In some examples, when the cleaning device 200 is docked on the base 10, the sewage holding tank 210 of the cleaning device 200 can be connected to the washing tank 101, and the sewage in the sewage holding tank 210 can be pumped into the washing tank 101. In this example, a negative pressure device for sucking out the sewage in the sewage holding tank 210 can be provided on the base 10, and a negative pressure device for pumping out the sewage in the sewage holding tank 210 can also be provided on the cleaning device 200.

[0106] In some examples, when the cleaning device 200 is docked on the base 10, a negative pressure device can be connected to the sewage holding tank 210 of the cleaning device 200, and the sewage in the sewage holding tank 210 can be pumped out to a preset location by the negative pressure device. Alternatively, the negative pressure device can be a negative pressure mechanism provided on the base 10, and the negative pressure mechanism on the base 10 can be used to pump out the sewage in the sewage holding tank 210 and transport it to a preset tank on the base 10 for temporary storage. Alternatively, the negative pressure mechanism can be used to pump out the sewage in the sewage holding tank 210 and directly transport it through a pipeline to a drainage device such as a drainage pool. Alternatively, the negative pressure device can be a negative pressure mechanism provided on the cleaning device 200, and the negative pressure mechanism on the cleaning device 200 can be used to pump out the sewage in the sewage holding tank 210 into a preset tank on the base 10 for temporary storage. Alternatively, the negative pressure mechanism on the cleaning device 200 can be used to transport the sewage in the sewage holding tank 210 through a pipeline to a drainage device such as a drainage pool.

[0107] Dust collecting unit 14.

[0108] Please refer again Figures 5 to 9 In some examples, the base station 100 further includes a dust collecting unit 14, which includes a dust collecting bin 143 and an air inlet port 141 and an air outlet port 142 respectively connected to the dust collecting bin 143. The dust collecting unit 14 can be fixedly or detachably connected to the base station 100.

[0109] The dust collecting portion 14 may be a hard box-like structure, or a deformable bag-like structure, or a combination of a hard box-like structure and a deformable bag-like structure.

[0110] The dust collecting part 14 is at least partially hollow, and the hollow portion inside the dust collecting part 14 forms a dust collecting bin 143. The air inlet port 141 and the air outlet port 142 are connected to the dust collecting bin 143, so that air can enter the dust collecting bin 143 from the air inlet port 141 and flow out along the air outlet port 142. In this example, optionally, a pipeline can be connected to the dust collecting part 14, and the pipeline can form a dust outlet air duct 144. The end of the pipeline away from the dust collecting part 14 can form the air inlet port 141. The air outlet port 142 can be used to connect to a device with a negative pressure function, and dust can be sucked into the dust collecting bin 143 from the air inlet port 141 by forming a negative pressure at the air outlet port 142; optionally, a negative pressure device can be connected to the air inlet port 141 to form a negative pressure at the air inlet port 141, so as to pump dust from the air inlet port 141 into the dust collecting bin 143. In some examples, the air inlet port 141 can be used to dock with the dust box 230 of the cleaning device 200 when the cleaning device 200 is docked with the base 10, so as to facilitate the suction of dust in the cleaning device 200 into the dust collecting section 14, thereby facilitating the cleaning of the dust box 230 of the cleaning device 200. Optionally, in this example, a device with a negative pressure function can be provided on the cleaning device 200, and the dust in the dust box of the cleaning device 200 is pumped into the dust collection bin 143 by the device with a negative pressure function. In some examples, the base station 100 is provided with an air duct opening 192 connected to the air outlet port 142. The air duct opening 192 can be used to connect to a device with a negative pressure function to form a negative pressure environment in the dust collecting section 14, so that dust can enter the dust collection bin 143 under the action of the negative pressure. In some examples, when the wet cleaner 20 is mounted on the base 10, the air duct opening 192 can be in contact with the wet cleaner 20, and the wet cleaner 20 can form a negative pressure on the air outlet port 142 of the dust collection bin 143. Optionally, the dust collection unit 14 includes a hard box-like structure. In the examples of the present application, the dust collection unit 14 can be an independent box connected to the base 10, or the dust collection unit 14 can be a cavity structure integrally formed with the base 10.

[0111] In some examples, the dust collecting portion 14 includes a dust bag, which can be used to contain solid impurities such as dust, and the dust collecting bin 143 is formed inside the dust bag.

[0112] In some examples, the dust collecting section 14 includes a dust bag, which can be used to hold solid impurities such as dust. The dust bag can be installed inside the dust collecting bin 143 to collect the solid impurities entering the dust collecting bin 143; optionally, the dust bag can also be installed at the air inlet port 141 or the air outlet port 142 of the dust collecting section 141; when the dust bag is inflated by wind, the outer contour of the dust bag can be roughly cylindrical; taking the dust bag as an example of being set inside the dust collecting bin 143, when the air flow enters the dust collecting bin 143 from the air inlet port 141, the dust in the air flow can be blocked in the dust bag, and the dust bag can collect solid impurities in the air flow to purify the air flow. The purified air flow can be output from the air outlet port 142, and the user can open the dust collecting section 14 when needed to clean or replace the dust bag.

[0113] Sewage recycling tank 1001.

[0114] Please refer to Figures 8 to 12 The sewage recovery tank 1001 can be used to accommodate sewage. The sewage recovery tank 1001 can be fixedly or detachably connected to the base 10. The sewage recovery tank 1001 can be used to collect sewage on the base 10, and can also be used to collect sewage on the cleaning device 200 when the cleaning device 200 is docked on the base 10.

The first transceiver 2181 can be configured to emit a photoelectric signal, and the second transceiver 2182 can be configured to receive the photoelectric signal emitted by the first transceiver 2181 . When the light shield 2183 blocks the optical path between the first transceiver 2181 and the second transceiver 2182 , the second transceiver 2182 cannot receive the photoelectric signal.

[0156] Optionally, the first transceiver 2181 is connected to the drain valve body 2166. The first transceiver 2181 is connected to the drain valve body 2166 so that the first transceiver 2181 can remain relatively fixed to the drain valve body 2166. Alternatively, taking the drain three-way valve 216 as an example, the wet cleaner 20 may be provided with a main control board 28, which may be an integrated circuit board on the wet cleaner 20. The main control board 28 is electrically connected to the first transceiver 2181, enabling signal transmission between the main control board 28 and the first transceiver 2181. Optionally, the main control board 28 can also be used to control the operation of the first transceiver 2181, thereby controlling the timing of signal transmission by the first transceiver 2181.

[0157] Optionally, a second transceiver 2182 is electrically connected to the main control board 28 and connected to the drain valve body 2166. The second transceiver 2182 can be used to receive the photoelectric signal sent by the first transceiver 2181. The second transceiver 2182 is connected to the drain valve body 2166 so that the second transceiver 2182 can remain fixed relative to the drain valve body 2166. The main control board 28 can be used to receive signals from the second transceiver 2182.

[0158] The light shielding plate 2183 is connected to the drain valve spool 2163 or the output end of the driver module 217. When the drain valve spool 2163 is in the first connection position, the light shielding plate 2183 blocks the light path between the first transceiver 2181 and the second transceiver 2182. When the drain valve spool 2163 is in the second connection position, the light shielding plate 2183 is spaced from the light path between the first transceiver 2181 and the second transceiver 2182. The output end of the driver module 217 is connected to the drain valve spool 2163. When the driver module 217 drives the drain valve spool 2163 to move, the light shielding plate 2183 can move synchronously. When the drain valve spool 2163 is in the first connection position, the photoelectric signal sent by the first transceiver 2181 to the second transceiver 2182 is blocked by the light shield 2183, and the second transceiver 2182 cannot receive the photoelectric signal. When the driver module 217 drives the drain valve spool 2163 to move to the second connection position, the light shield 2183 moves synchronously and can be removed from the optical path between the first transceiver 2181 and the second transceiver 2182, allowing the second transceiver 2182 to receive the photoelectric signal sent by the first transceiver 2181. In this example, the main control board 28 determines whether the drain valve spool 2163 is currently in the first connection position or the second connection position by receiving the photoelectric signal from the detection device 218, and then controls the operating parameters of the driver module 217 as needed.

[0159] It is understandable that the first transceiver device 2181 and the second transceiver device 2182 can also be installed at the output end of the driving module 217 or the drain valve spool 2163, and the shading plate 2183 can be installed on the drain valve body 2166, so that when the driving module 217 can drive the drain valve spool 2163 to move between the first connection position and the second connection position, the shading plate 2183 can block the light path between the first transceiver device 2181 and the second transceiver device 2182.

[0160] In some examples, the sewage valve body 2166 further includes a valve body cover 2165 , the valve body cover 2165 is connected to the sewage valve body 2166 , and the driving module 217 is connected to the valve body cover 2165 .

[0161] The drain valve body 2166 may serve as the main structure of the drain valve body 2166 , and the driving module 217 may be disposed outside the drain valve body 2166 .

[0162] The valve body cover 2165 can be connected between the driver module 217 and the sewage flow channel 2167 to support the driver module 217 and can also be used to seal the connection between the sewage valve spool 2163 and the driver module 217. Optionally, the valve body cover 2165 can be provided with a through hole, and the driving end of the driver module 217 can pass through the through hole in the valve body cover 2165 and be driven and connected to the sewage valve spool 2163. Optionally, the signal transmitter and signal receiver of the detection device 218 can be connected to the valve body cover 2165, and the light shielding plate 2183 can be connected to the output end of the driver module 217. Alternatively, the light shielding plate 2183 can be connected to the valve body cover 2165, and the signal transmitter and signal receiver can be connected to the output end of the driver module 217.

[0163] In some examples, the drain valve body 2166 further includes a sealing layer 2168, which is sealed between the outer wall of the drain valve core 2163 and the inner wall of the drain valve body 2166. The sealing layer 2168 can be used to seal the gap between the drain valve core 2163 and the inner wall of the drain valve body 2166 to reduce the possibility of water leakage from the drain valve body 2166. In this example, the sealing layer 2168 can be attached to the inner wall of the drain valve body 2166. Optionally, the sealing layer 2168 can also be sleeved on the outer wall of the drain valve core 2163. Through holes can be provided in the sealing layer 2168 at locations corresponding to the through hole 2164, the drain outlet 2162, the water inlet 2161a, and the gas inlet 2161b to facilitate the flow of medium.

[0164] Wet cleaner 20.

[0165] Please refer to Figure 9 、 Figure 10 as well as Figure 11 The wet cleaner 20 is detachably mounted on the base 10 , and is used to clean the surface to be cleaned.

[0166] The wet cleaner 20 can be used to clean a surface to be cleaned, such as a floor, carpet, sofa, mattress, etc. The wet cleaner 20 is detachably mounted on the base 10, meaning that the wet cleaner 20 can be removed from the base 10 and used alone to clean the surface to be cleaned, or the wet cleaner 20 can be mounted on the base 10.

[0167] See also Figure 12In this example, the base 10 can serve as a support mechanism for the wet cleaner 20. Optionally, the base 10 also includes a power supply module 15; the wet cleaner 20 also includes a second power supply module 26. When the wet cleaner 20 is mounted on the base 10, the base 10 can also be used to charge the wet cleaner 20. The second power supply module 26 can be a battery module with charging and discharging functions. In this example, the power supply module 15 can charge the second power supply module 26 via wired charging or wireless charging.

[0168] In some examples, the wet cleaner 20 further includes an external power cord, which can be used to receive commercial power and to charge the second power module 26 .

[0169] See also Figures 12 to 16 In some examples, the second power module 26 includes a main control board 28 , which can be used to control the operating state of the wet cleaner 20 . The main control board 28 can be a circuit board or an integrated board. An electrical control box 281 for accommodating the main control board 28 can be provided in the housing 29 .

[0170] In some examples, the wet cleaner 20 may be a fabric cleaner, which may be used to clean a fabric surface. The fabric cleaner may have a cleaning function, and may also have at least one of negative pressure suction and drying functions.

[0171] In this example, by installing the wet cleaner 20 on the base 10, on the one hand, the wet cleaner 20 can be supported by the base 10, and on the other hand, the wet cleaner 20 can be charged directly on the base 10 to simplify the charging components of the wet cleaner 20 and improve the integration performance of various cleaning equipment. On the other hand, it is convenient to store the wet cleaner 20, reduce the space occupied, and improve the utilization rate of the base station 100.

[0172] Please refer to Figure 4 and Figure 5In some examples, the wet cleaner 20 is provided with a sewage docking port 272 for docking with the sewage transfer port 122. When the wet cleaner 20 includes the above-mentioned shell 29, the sewage docking port 272 can be provided on the shell 29. In this example, by switching the connection state of the sewage discharge power device 215, the sewage discharge power device 215 can be used as a negative pressure source during the use of the cleaner 24; the sewage discharge power device 215 can also be used as a negative pressure source when the base station 100 cleans the sewage holding tank 210 of the cleaning equipment 200. When cleaning the sewage holding tank 210 of the cleaning equipment 200 or the water washing tank 101 of the base 10, the base 10 can be used only to dock with the cleaning equipment 200, or the base 10 can be used only to provide the second sewage circuit 12. The sewage does not need to be stored in the base 10. On the one hand, the sewage storage structure for storing sewage on the base 10 can be reduced or reduced, which helps to simplify the structure of the base 10 and improve the base. On the other hand, the space utilization of 10 is improved, which facilitates the cleaning operation of the base 10. On the other hand, it can shorten the residence time of sewage on the base 10, reduce the storage volume and residence time of pollutants on the base 10, reduce the possibility of bacteria breeding on the base 10, and improve the cleanliness of the base 10. On the other hand, a space for sewage flow is formed through the second sewage loop 12. When the cleaning equipment 200 is docked on the base 10, it is convenient to dock the cleaning equipment 200 with the sewage transfer interface 122, thereby reducing the operating steps of connecting the cleaning equipment 200 and the sewage three-way valve 216 through the external pipeline, thereby simplifying user operations and improving the automation performance of the process of docking the base station 100 with the cleaning equipment 200.

[0173] Cleaner 24.

[0174] Please refer to Figure 10 In some examples, the wet cleaner includes a washer 24 , which can be used to clean the surface to be cleaned.

[0175] In some examples, the washer 24 also includes a first sewage circuit 242, which can be connected to the washer 24 and used to draw sewage from the surface to be cleaned. In this example, the surface to be cleaned can be pre-sprayed with clean water, a cleaning solution, or a mixture of clean water and cleaning solution. When the washer 24 cleans the surface to be cleaned, sewage is generated. The inlet of the first sewage circuit 242 can be located near the washer 24 to draw the sewage generated by the washer 24 to a predetermined location. The first sewage circuit 242 can be a water flow channel formed by a hose, or a channel formed by a combination of a hose and a rigid tubular structure.

[0176] The cleaner 24 in the example of the present application may have a brush head 241; the brush head 241 can be used to scrub the surface to be cleaned. The brush head 241 can be a hair brush, a rubber brush, or a combination of a hair brush and a rubber brush. In some examples, the brush head 241 is fixedly connected to the cleaner 24, wherein the cleaner 24 can be detachably connected to the first sewage circuit 242 to facilitate cleaning and replacement. In some examples, the brush head 241 can be detachably connected to the cleaner 24, and only the brush head 241 can be replaced when necessary for cleaning in different scenarios. In some examples, the brush head 241 includes a combination of a hair brush and a rubber brush, wherein at least one of the hair brush and the rubber brush is detachably connected to the cleaner 24.

[0177] See also Figures 17 to 23 In some examples, the base station 100 includes the sewage discharge power unit 215 described in any of the above examples. The sewage discharge power unit 215 can be located outside the base 10. Optionally, the sewage discharge power unit 215 can be located on the wet cleaner 20 and can be detachably connected to the base 10. The sewage discharge power unit 215 can create a negative pressure at a preset location to suck sewage from the surface to be cleaned. The sewage discharge power unit 215 is used to create a negative pressure state at a preset location on the wet cleaner 20. Under the action of the negative pressure, the sewage from the surface to be cleaned can be sucked into the preset location within the wet cleaner 20. In this example, the sewage discharge power unit 215 can optionally be a fan, which creates a negative pressure state at a preset location on the wet cleaner 20 to facilitate suction of sewage from the surface to be cleaned. In some examples, the wet cleaner 20 includes the housing 29 described in any of the above examples, and the sewage discharge power unit 215 can be connected to the housing 29.

[0178] In some examples, the sewage power unit 215 is also used to extract sewage from the sewage holding tank 210 of the cleaning device 200 when the wet cleaner 20 is mounted on the base 10 and the cleaning apparatus 200 is docked on the base 10. When the wet cleaner 20 is mounted on the base 10, the sewage power unit 215 can dock with the sewage transfer port 122. When the cleaning apparatus 200 is docked on the base 10, the sewage power unit 215 can be activated to extract sewage from the sewage holding tank 210 of the cleaning apparatus 200. In this example, the sewage power unit 215 can dock with the sewage transfer port 122 when the cleaning apparatus 200 is docked on the base 10, so that the sewage power unit 215 creates a negative pressure at the sewage transfer port 122, thereby extracting sewage from the sewage holding tank 210 and draining the cleaning apparatus 200. In this example, the sewage extracted from the sewage holding tank 210 of the cleaning apparatus 200 by the sewage power unit 215 can be discharged to a predetermined location.

[0179] In some examples, the sewage discharge power unit 215 is connected to the end of the first sewage circuit 242 away from the brush head 241. When the sewage discharge power unit 215 is activated, the sewage discharge power unit 215 can create negative pressure in the first sewage circuit 242 to suck the sewage at the brush head 241 to a preset location. The sewage discharge power unit 215 in this example can be used to suck sewage from the sewage holding tank 210 when the wet cleaner 20 is installed on the base 10 and the cleaning device 200 is docked on the base 10 to clean the cleaning device 200. The sewage discharge power unit 215 can also be used to cooperate with the brush head 241 to suck sewage from the surface to be cleaned to a preset location when the wet cleaner 20 is used alone. This allows the two functional modules to share the sewage discharge power unit 215, thereby helping to simplify the structure of the base station 100. The base 10 in this example can only be used to provide a second sewage circuit 12. When the cleaning equipment 200 is docked on the base 10, when the sewage in the sewage holding tank 210 of the cleaning equipment 200 is sucked out, the sewage may not be stored in the base 10, so as to simplify the structure of the base 10, reduce the accumulation of dirt in the base 10, and help improve the sanitary performance of the base 10.

[0180] In some examples, the sewage discharge power device 215 is installed on the wet cleaner 20, and the sewage discharge power device 215 is connected to the washing tank 101 through the second sewage circuit 12. When the wet cleaner 20 is installed on the base 10, the sewage in the washing tank 101 can be pumped out to a preset position through the sewage discharge power device 215.

[0181] A first sewage tank 21 .

[0182] Please refer to Figures 25 to 28 The first sewage tank 21 can be used to store sewage. The first sewage tank 21 has a sewage chamber 219, a sewage inlet 211 connected to the sewage chamber 219, and an air outlet 214. The first sewage tank 21 can serve as a sewage storage mechanism on the wet cleaner 20. The first sewage tank 21 is at least partially hollow, forming the sewage chamber 219 for storing sewage. The first sewage tank 21 also has a sewage inlet 211 connected to the sewage chamber 219, and an air outlet 214. The sewage inlet 211 can be used to allow sewage to enter the sewage chamber 219, and the air outlet 214 can be used to connect to an external negative pressure device.

[0183] Please refer to Figures 13 to 20In this example, the air outlet 214 can be connected to a sewage discharge power unit 215, which is used to generate negative pressure within the sewage chamber 219. The sewage discharge power unit 215 in this example can be used to draw sewage from the cleaning device 200 into the sewage chamber 219 when the cleaning device 200 is docked on the base 10, thereby facilitating cleaning of the cleaning device 200. In some examples, the wet cleaner 20 includes the housing 29 described in the above examples. The first sewage tank 21 can be fixedly mounted on the housing 29, or the first sewage tank 21 can be detachably mounted on the housing 29. Optionally, the wet cleaner 20 is provided with the sewage discharge three-way valve 216 described in any of the above examples. The waterway inlet 2161a of the sewage discharge three-way valve 216 is connected to the sewage inlet 211. In some examples, the wet cleaner 20 is provided with a sewage docking port 272 for docking with the sewage transfer port 122. Optionally, the sewage docking port 272 can be connected to the first sewage tank 21 through a pipeline. When the wet cleaner 20 includes the above-mentioned shell 29, the sewage docking port 272 can be provided on the shell 29.

[0184] In this example, the sewage inlet 211 of the sewage discharge power unit 215 can be provided with two channels connected to the sewage chamber 219, one of which is used to connect to the first sewage circuit 242, and the other is used to connect to the sewage transfer port 122 when the wet cleaner 20 is installed on the base 10. Optionally, the sewage inlet 211 of the sewage discharge power unit 215 can also connect the first sewage circuit 242 and the sewage transfer port 122 via a structure such as a multi-channel valve. In some examples, the wet cleaner 20 also includes a second power module 26 in any of the above examples. The second power module 26 can be electrically connected to the sewage discharge power unit 215 to power the sewage discharge power unit 215.

[0185] Please refer to Figures 25 to 29 In some examples, the wet cleaner 20 further includes a sewage tee 212 having a sewage flow channel, an outlet 2121 connected to the sewage flow channel, a first sewage interface 2122, and a second sewage interface 2123. The outlet 2121 is connected to the sewage inlet 211, the first sewage interface 2122 is connected to the first sewage circuit 242, and the second sewage interface 2123 is used to connect to the sewage transfer interface 122 when the wet cleaner 20 is installed on the base 10. In some examples, the wet cleaner 20 is provided with a sewage connection interface 272 for connecting to the sewage transfer interface 122, and the second sewage interface 2123 can be connected to the sewage connection interface 272.

[0186] The sewage tee 212 has a sewage flow channel. The first sewage interface 2122, the second sewage interface 2123, and the water outlet 2121 are openings on the sewage tee 212 that connect to the sewage flow channel. Sewage can enter the sewage flow channel through the first sewage interface 2122 or the second sewage interface 2123 and be discharged through the water outlet 2121. In this example, the water outlet 2121 is connected to the sewage inlet 211 of the first sewage tank 21, so that sewage input from the first sewage interface 2122 or the second sewage interface 2123 can enter the sewage chamber 219. In this example, the first sewage interface 2122 is connected to the first sewage circuit 242, so that sewage generated by the cleaning device 24 when cleaning the surface to be cleaned can enter the sewage chamber 219 through the first sewage circuit 242 and the first sewage interface 2122. When the wet cleaner 20 is mounted on the base 10, the second sewage interface 2123 can be connected to the sewage transfer interface 122. When the cleaning device 200 is docked on the base 10, sewage from the washing tank 101 and / or the cleaning device 200 can enter the second sewage interface 2123 via the second sewage circuit 12 and then enter the first sewage tank 21 for storage. In this example, the sewage tee pipe 212 can form two waterways, either of which can be opened selectively or simultaneously.

[0187] In this example, by providing the sewage tee pipe 212 , two water inlet ports can be formed at the sewage inlet of the first sewage tank 21 , thereby facilitating the input of sewage from the washer 24 and the cleaning device 200 .

[0188] See also Figure 28 and Figure 29In some examples, the wet cleaner 20 further includes a sewage control valve 213, which is at least partially disposed within the sewage flow path of the sewage tee 212. The sewage control valve 213 is used to control whether one of the first sewage interface 2122 and the second sewage interface 2123 is connected to the water outlet 2121. The sewage control valve 213 can be used to switch the water flow path of the sewage tee 212. The sewage control valve 213 can be used to connect the first sewage interface 2122 and the water outlet 2121, or the second sewage interface 2123 and the water outlet 2121, thereby controlling the switching of the water flow path of the sewage tee 212. In this example, the sewage control valve 213 can be mechanically or electrically driven, so that the sewage control valve 213 can move relative to the sewage tee 212, thereby switching the water flow path of the sewage tee 212. Optionally, a motor may be provided on the outside of the sewage tee 212 to drive the sewage control valve 213 to rotate relative to the sewage tee 212 to control the switching of the water flow path of the sewage tee 212. Optionally, when the wet cleaner 20 is used alone, the sewage control valve 213 may control the first sewage interface 2122 to connect to the water outlet 2121. When the wet cleaner 20 is installed on the base 10, the sewage control valve 213 may control the second sewage interface 2123 to connect to the water outlet 2121. The sewage control valve 213 in this example can be installed at a preset position on the sewage tee 212 to control the water flow state of the sewage tee 212. Optionally, the number of sewage control valves 213 can be multiple, and sewage control valves 213 can be respectively set on the first sewage interface 2122 and the second sewage interface 2123 to respectively control the opening and closing states of the first sewage interface 2122 and the second sewage interface 2123. The said respective control of the opening and closing states of the first sewage interface 2122 and the second sewage interface 2123 can include opening one of the first sewage interface 2122 and the second sewage interface 2123 and closing the other, or controlling the first sewage interface 2122 and the second sewage interface 2123 to be partially open or fully open respectively through the sewage control valve 213.

Optionally, the second sewage connection 2123 can be used to connect to the sewage transfer port 122 when the wet cleaner 20 is installed on the base 10. When the operating state of the sewage three-way valve 2110 is switched, the sewage three-way valve 2110 can be switched between the two water flow paths described above, thereby connecting one of the first sewage circuit 242 and the sewage transfer port 122 to the first sewage tank 21. The sewage three-way valve 2110 in this example can include the sewage three-way pipe 212 and the sewage control valve 213 described in any of the above examples, and the water flow path state of the sewage three-way pipe 212 can be controlled by the sewage control valve 213.

[0190] In some examples, the wet cleaner 20 is provided with a three-way sewage discharge valve 216, which has a sewage discharge flow channel 2167 and a sewage discharge outlet 2162, a water path inlet 2161a and an air path inlet 2161b respectively connected to the sewage discharge flow channel 2167.

The water path inlet 2161a of the sewage discharge three-way valve 216 is used to connect to the air outlet port 142 when the wet cleaner 20 is installed on the base 10. The sewage discharge three-way valve 216 has a first connection position connecting the first sewage tank 21 and the sewage discharge power device 215 and a second connection position connecting the dust collecting part 14 and the sewage discharge power device 215.

[0191] The sewage outlet 2162 of the three-way sewage valve 216 is connected to the inlet of the sewage discharge power unit 215; the water inlet 2161a is connected to the air outlet 214, so that when the sewage discharge power unit 215 is activated, a negative pressure is generated in the sewage chamber 219; when the wet cleaner 20 is installed on the base 10, the air inlet 2161b is connected to the air outlet port 142, so that when the sewage discharge power unit 215 is activated, a negative pressure is generated in the dust collection bin 143.

When the three-way sewage discharge valve 216 is in the first connection position, the first sewage tank 21 and the sewage discharge power unit 215 are connected to each other. When the sewage discharge power unit 215 is activated, a negative pressure state can be formed in the first sewage tank 21, allowing sewage to enter the sewage chamber 219 through the sewage inlet 211. When the three-way sewage discharge valve 216 is in the second connection position, the dust collection box 230 can be connected to the sewage discharge power unit 215. When the sewage discharge power unit 215 is activated, a negative pressure state can be formed in the dust collection bin 143, allowing dust in the dust collection box 230 of the cleaning device 200 to enter the dust collection bin 143 through the air inlet port 141. Optionally, the sewage discharge power unit 215 can be a dual-purpose dry and wet fan.

[0192] Pipes can be provided on the drain valve body 2166, the water inlet 2161a, and the air inlet 2161b, respectively. The pipe connected to the water inlet 2161a can be connected to the air outlet 214 of the first sewage tank 21, and the pipe connected to the air inlet 2161b can extend to the second wall 27 of the wet cleaner 20 for docking with the air duct opening 192.

[0209] In this example, the first clean water tank 22 can be used to replenish the clean water holding tank 220 of the cleaning device 200. When the wet cleaner 20 is mounted on the base 10 and the cleaning device 200 is docked to the base 10, the outlet of the water supply power unit 23 can be connected to the clean water holding tank 220. When the water supply power unit 23 is in operation, the water supply power unit 23 can be used to pump clean water from the first clean water tank 22 into the clean water holding tank 220 to replenish the clean water holding tank 220. Because the wet cleaner 20 is detachable from the base 10, in this example, the wet cleaner 20 can be used to supply water to the cleaning device 200 while the cleaning device 200 is docked on the base 10, thereby reducing the difficulty of replenishing the cleaning device 200. Optionally, the water supply power unit 23 can have two outlets, one of which is used to connect to the water supply receiving port 131 when the wet cleaner 20 is mounted on the base 10, and the other outlet can be used to connect to the first water supply circuit 243.

The inlet of the water supply control valve 25 is connected to the water supply power unit 23, and the clean water output by the water supply power unit 23 enters the water supply control valve 25. The outlet of the water supply control valve 25 can be connected to the first water supply circuit 243 for outputting water to the surface to be cleaned. The outlet of the water supply control valve 25 can also be used to connect to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10. Optionally, the water supply control valve 25 can have one inlet and two outlets, wherein one outlet can be used to connect to the first water supply circuit 243, and the other outlet can be used to connect to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10. In some examples, the wet cleaner 20 is provided with a clean water docking port 273 for docking with the water supply receiving port 131 . Optionally, the clean water docking port 273 may be provided on the housing 29 .

[0212] In some examples, the water supply control valve 25 includes a water supply valve body 251 and a water supply valve core 252; the water supply valve body 251 is formed with a water supply channel and a clean water inlet 2511, a first clean water outlet 2512 and a second clean water outlet 2513 respectively connected to the water supply channel, the clean water inlet 2511 is connected to the outlet of the water supply power device 23, the first clean water outlet 2512 is connected to the first water supply circuit 243, and the second clean water outlet 2513 is used to connect to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10.

The clean water inlet 2511 is connected to the outlet of the water supply power unit 23, so that water output by the water supply power unit 23 can enter the water supply channel. The first clean water outlet 2512 is used to connect to the first water supply circuit 243. When the water in the water supply channel is output through the first clean water outlet 2512, the first clean water tank 22 can be used to supply water to the surface to be cleaned. The second clean water outlet 2513 is used to connect to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10, so that the first clean water tank 22 can be used to replenish water to the clean water storage tank 220 of the cleaning device 200 docked on the base 10. The water supply channel described in the examples of this application can be used to transport clean water or a mixture of clean water and cleaning liquid.

[0215] The clean water drain valve core 2163 in this example can move relative to the water supply valve body 251, which means that the clean water drain valve core 2163 can rotate, slide, or a combination of rotation and sliding relative to the water supply valve body 251. When the water supply valve core 252 moves relative to the water supply valve body 251, the water supply valve core 252 is used to control the switching of the water flow path in the water supply channel. When the wet cleaner 20 is used alone and needs to spray water onto the surface to be cleaned, the water supply valve core 252 can control the connection between the clean water inlet 2511 and the first clean water outlet 2512, so that the water in the first clean water tank 22 can be delivered to the first water supply circuit 243. When the cleaning device 200 is docked on the base 10 and needs to replenish water to the clean water holding tank 220 of the cleaning device 200, the water supply valve core 252 can be used to control the connection between the clean water inlet 2511 and the second clean water outlet 2513, so that the water in the first clean water tank 22 can enter the water supply receiving port 131 in sequence through the water supply power device 23, the clean water inlet 2511, and the second clean water outlet 2513. Optionally, the water supply valve can be driven to move relative to the water supply valve body 251 by an electric drive, or it can be driven to move relative to the water supply valve body 251 by a mechanical drive.

The switch 253 in this example may be a valve body with a flow control function. In this example, by using the switch 253 to control the opening of the first water supply circuit 243, when the wet cleaner 20 is used alone, the switch 253 can be used to control the time or amount of water output from the first water supply circuit 243 for cleaning in different scenarios.

The second one-way valve 256 is used to control the flow of clean water from the second clean water outlet 2513 to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10 .

[0222] The second one-way valve 256 is used to control the one-way flow of water output from the second clean water outlet 2513. In this example, the inlet of the second one-way valve 256 can be connected to the second clean water outlet 2513 of the water supply control valve 25. When the wet cleaner 20 is installed on the base 10, the second one-way valve 256 can ensure that the water output from the second clean water outlet 2513 flows in a one-way direction toward the water supply receiving port 131, thereby reducing the possibility of the clean water flowing back into the second clean water outlet 2513.

[0224] Cleaning liquid can be used as a solution for cleaning surfaces. Liquid tank 257 is used to store the cleaning liquid. The outlet of liquid tank 257 can be connected to the inlet of water supply unit 23. When water supply unit 23 is in operation, water supply unit 23 can draw the cleaning liquid from liquid tank 257 into water supply control valve 25. The cleaning liquid in this example can be used solely in wet cleaner 20, or it can be used in cleaning equipment 200.

The main control board 28 can be used to control the operation of the cleaning liquid power unit 258, so that the cleaning liquid power unit 258 can pump cleaning liquid from the liquid storage tank 257 and deliver the cleaning liquid to the inlet of the water supply power unit 23. The main control board 28 can also be used to control the operation of the water supply power unit 23, so that the water supply power unit 23 can pump clean water from the first clean water tank 22. The clean water and cleaning liquid can be mixed at the water supply power unit 23, thereby forming a mixed liquid. Optionally, in this example, the working time and operating power of the cleaning liquid power device 258 and the water supply power device 23 can be controlled to adjust the flow rate of clean water and cleaning liquid according to the condition of the surface to be cleaned, thereby adjusting the concentration of the cleaning liquid in the mixed liquid.

[0230] Please continue reading Figure 24In some examples, the wet cleaner 20 further includes a flow detection assembly 221, which is connected between the first clean water tank 22 and the water supply power unit 23 and is used to detect the flow rate of water output from the first clean water tank 22. The flow detection assembly 221 can be used to detect the amount of water output from the first clean water tank 22, thereby monitoring the water level within the first clean water tank 22. In this example, the flow detection assembly 221 can be a flow meter or other component capable of detecting liquid flow. In some examples, the wet cleaner 20 includes a second power supply module 26 in any of the above examples. The flow detection assembly 221 can be electrically connected to the second power supply module 26 so that the second power supply module 26 can power the flow detection assembly 221. In some examples, the first clean water tank 22 is used to supply water to the exterior of the wet cleaner 20 for washing and cleaning the surface to be cleaned. The flow detection assembly 221 can be used to detect the amount of water output from the first clean water tank 22, thereby reminding the user to add water when the water level in the first clean water tank 22 reaches a preset level. In some examples, the first clean water tank 22 is used to replenish water to the washing tank 101. The flow detection assembly 221 can be used to detect the amount of water output from the first clean water tank 22 to prevent overflow of the washing tank 101. In some examples, the first clean water tank 22 is used to supply water to the surfaces of wet cleaning components of the cleaning device 200 for washing the wet cleaning components. The flow detection assembly 221 can be used to detect the amount of water in the first clean water tank 22 to prompt the user to add water. In some examples, the first clean water tank 22 is used to replenish water to the clean water holding tank of the cleaning device 200. The flow detection assembly 221 can be used to detect the amount of water in the first clean water tank 22. This can prevent overflow of the clean water holding tank and facilitate prompting the user to add water in a timely manner.

[0231] See also Figure 5 and Figure 11 In some examples, the wet cleaner 20 has a second wall 27 and a housing 29. The second wall 27 is a side wall of the housing 29. When the wet cleaner 20 is mounted on the base 10, the second wall 27 of the wet cleaner 20 can be positioned opposite the first wall 19 of the base 10. Optionally, the second wall 27 can be aligned with the first wall 19. Optionally, functional components for docking with the sewage transfer port 122, the water supply receiving port 131, and the air duct port 192 can be provided on the second wall 27, so that the corresponding ports can dock with each other during installation of the wet cleaner 20 on the base 10.

[0232] In some examples, the power supply module 15 includes a first docking terminal 151, which can be disposed on the first wall 19. The wet cleaner 20 includes a second power supply module 26, which can be connected to an external power supply device to power internal components of the wet cleaner 20. The second power supply module 26 can include a second docking terminal 261 for docking with the first docking terminal 151, which can be disposed on the second wall 27. When the wet cleaner 20 is installed on the base 10 and the cleaning device 200 is docked at a preset position on the base 10, the power supply module 15 can be used to charge at least one of the second power module 26 and the cleaning device 200; the power supply may include the power supply module 15 continuously providing power to the second power module 26, and the power supply may also include the power supply module 15 charging the second power module 26; at the same time, the wet cleaner 20 can be docked with the sewage transfer port 122, the water supply receiving port 131, and the air duct port 192 on the base 10 to facilitate cleaning of the cleaning device 200.

[0233] In some examples, the wet cleaner 20 has a sewage docking port 272 for docking with the sewage transfer port 122, a clean water docking port 273 for docking with the water supply receiving port 131, and an air duct docking port 274 for docking with the air duct port 192. Optionally, the sewage docking port 272, the air duct docking port 274, and the clean water docking port 273 can all be arranged on the second wall 27.

[0234] In some examples, the wet cleaner 20 has a main control board 28 in any of the above examples, and the main control board 28 is electrically connected to the second power module 26. In some examples, the power supply module 15 includes a first docking terminal 151, and the second power module 26 includes a second docking terminal 261. When the wet cleaner 20 is installed on the base 10, the first docking terminal 151 and the second docking terminal 261 are electrically connected. In this example, the first docking terminal 151 and the second docking terminal 261 can be PIN pins or other structures that can be used for electrical signal transmission. Optionally, the first docking terminal 151 and the second docking terminal 261 can both be multiple groups, and the multiple groups of the first docking terminal 151 and the second docking terminal 261 can be set in a one-to-one correspondence. In some examples, the first docking terminal 151 and the second docking terminal 261 can be two groups of quick-connect connectors. In some examples, the first docking terminal 151 and the second docking terminal 261 can be point contact, surface contact or line contact, and the docking state of the first docking terminal 151 and the second docking terminal 261 can be changed by changing the position and contact area of ​​the contact surface of the first docking terminal 151 and the second docking terminal 261.

[0235] Please refer to Figure 5 and Figure 11In some examples, one of the first wall 19 and the second wall 27 is provided with a limiting protrusion 191, and the other is provided with a limiting groove 271. When the wet cleaner 20 is installed on the base 10, the limiting protrusion 191 is at least partially embedded in the limiting groove 271.

[0236] The limiting protrusion 191 is a structure protruding from the surface of the corresponding structure, and the limiting groove 271 is a groove recessed in the surface of the corresponding structure. The limiting protrusion 191 can be provided on the wet cleaner 20 and the limiting groove 271 can be provided on the base 10, or the limiting groove 271 can be provided on the wet cleaner 20 and the limiting protrusion 191 can be provided on the base 10, or the limiting groove 271 and the limiting protrusion 191 can be provided on the wet cleaner 20 and the base 10, respectively. The limiting protrusion 191 on the base 10 is inserted into the limiting groove 271 on the wet cleaner 20, and the limiting protrusion 191 on the wet cleaner 20 is inserted into the limiting groove 271 on the base 10. In this example, the shape of the limiting protrusion 191 can be consistent with the shape of the corresponding limiting groove 271. When the wet cleaner 20 is installed on the base 10, the limiting protrusion 191 and the limiting groove 271 can cooperate to initially position the wet cleaner 20, thereby facilitating mutual alignment of the wet cleaner 20 and the base 10. When the wet cleaner 20 is installed on the base 10, the limiting protrusion 191 and the limiting groove 271 can be used to limit the movement of the wet cleaner 20 in a specific direction relative to the base 10. For example, when the limiting protrusion 191 and the limiting groove 271 are arranged vertically, after the limiting protrusion 191 is inserted into the limiting groove 271, it can prevent the wet cleaner 20 from moving horizontally relative to the base 10, thereby improving the stability of the wet cleaner 20.

[0237] In some examples, there can be multiple limiting protrusions 191 and multiple limiting grooves 271, with each limiting protrusion 191 having at least one corresponding limiting groove. In some examples, the generally contours of the limiting protrusions 191 and the limiting grooves 271 can be triangular, quadrilateral, pentagonal, hexagonal, elliptical, etc., so that when the wet cleaner 20 is mounted on the base 10, the wet cleaner 20 cannot rotate relative to the base 10, thereby maintaining the wet cleaner 20 in a predetermined state.

[0238] Please refer to Figure 35 and Figure 36 In some examples, the base 10 can be used to charge the wet cleaner 20. When the limiting groove 271 and the limiting protrusion 191 cooperate with each other, the electrical connection between the base 10 and the wet cleaner 20 can be facilitated, reducing the mutual misalignment between the two, and thereby reducing the circuit breakage caused by inaccurate docking.

[0239] In some examples, the wet cleaner 20 includes a housing 29, which is provided with a sewage docking port 272 connected to the first sewage tank 21, a clean water docking port 273 connected to the first clean water tank 22, and an air duct docking port 274 connected to the sewage discharge power unit 215. The sewage docking port 272 can be used to dock with the sewage transfer port 122 of the base 10, the clean water docking port 273 can be used to dock with the water supply receiving port 131 of the base 10, and the air duct docking port 274 can be used to dock with the air duct port 192 of the base 10. In this example, when the limiting protrusion 191 and the limiting groove engage with each other, the relative position of the wet cleaner 20 and the base 10 is also determined, so that the sewage docking port 272, the clean water docking port 273, and the air duct docking port 274 are in a preset position, facilitating docking between the ports.

[0240] See also Figure 37 、 Figure 38 、 Figure 39 as well as Figure 40 In some examples, when the wet cleaner 20 is mounted on the base 10, the second wall 27 is located above the first wall 19. The second wall 27 is a wall surface at the bottom of the wet cleaner 20. When the wet cleaner 20 is mounted on the base 10, the second wall 27 can abut against the first wall 19, and the second power module 26 can be hidden between the contact area between the wet cleaner 20 and the base 10 to improve the safety of the wet cleaner 20 when charging.

[0241] In some examples, the second wall 27 is provided with a limiting groove 271, and the second docking terminal 261 is at least partially located within the limiting groove 271. The limiting groove 271 in this example can be used to accommodate the second docking terminal 261, so that the second docking terminal 261 can be received within the limiting groove 271. When the wet cleaner 20 is moved, the second wall 27 of the wet cleaner 20 can be used as its bottom wall to place the wet cleaner 20 on the ground, a table, or other surfaces, thereby reducing the impact of the second docking terminal 261 on the wet cleaner 20 and helping to improve the stability of the wet cleaner 20.

[0242] In some examples, the first wall 19 is provided with a limiting protrusion 191, which is disposed adjacent to the first docking terminal 151. The limiting protrusion 191 can be used to form an overhead area adjacent to the first docking terminal 151, thereby protecting the first docking terminal 151 when the wet cleaner 20 or other objects approach the first docking terminal 151. The limiting protrusion 191 being disposed adjacent to the first docking terminal 151 means that the limiting protrusion 191 is disposed adjacent to the first docking terminal 151. Alternatively, the limiting protrusion 191 can be a rib or a ring disposed adjacent to the first docking terminal 151.

[0243] Please refer to Figure 41 and Figure 42 In some examples, the base 10 further comprises a bracket 193 connected to the limiting protrusion 191, which can be used to support the power supply module 15 to fix the power supply module 15 at a preset position on the base 10.

[0244] Optionally, the limiting protrusion 191 in the present example can be arranged around the outer periphery of the bracket 193, which can be used to form a protruding structure around the outer periphery of the bracket 193. When foreign matter approaches the bracket 193, the limiting protrusion 191 can block the foreign matter to prevent the foreign matter from directly abutting the bracket 193.

[0245] In some examples, the bracket 193 has a bottom wall 1934 and a side wall 1935 arranged around the periphery of the bottom wall 1934, the side wall 1935 is arranged protruding outwardly from the first wall 19, the limiting protrusion 191 is arranged around the side wall 1935, and the power supply module 15 is connected to the bottom wall 1934. The bottom wall 1934 can be used to support the power supply module 15, and the power supply module 15 can be connected to the bottom wall 1934 by welding or screws. The side wall 1935 is arranged around the periphery of the bottom wall 1934, which means that the side wall 1935 is connected to the peripheral part of the bottom wall 1934. The side wall 1935 is arranged protruding outwardly from the first wall 19, which means that the end of the side wall 1935 away from the bottom wall 1934 protrudes from the surface of the first wall 19. The side wall 1935 forms a concave area on one side of the bottom wall 1934, which can be used to accommodate the first connecting terminal 151 of the power supply module 15. In the present example, the bracket 193 can be protected by the limiting protrusion 191, and the limiting protrusion 191 can also block foreign matter from contacting the first connecting terminal 151. The bracket 193 in the present example can form an annular area, which is surrounded by the side wall 1935 of the bracket 193 around the periphery of the power supply module 15, so that the power supply module 15 can be partially hidden in the concave area formed by the bracket 193, thereby reducing the damage to the power supply module 15.

[0246] Please refer again to Figure 38In some examples, the power supply module 15 includes an electronic control board 152 and a first docking terminal 151 as described in any of the above examples. In some examples, a limiting protrusion 191 is provided around the periphery of the first docking terminal 151. The limiting protrusion 191 can be used to form a convex ring around the periphery of the first docking terminal 151, so that the limiting protrusion 191 can protect the first docking terminal 151. Optionally, in some examples, the height of the limiting protrusion 191 protruding from the first wall 19 is higher than the height of the first docking terminal 151 protruding from the first wall 19, so as to further protect the first docking terminal 151. Specifically, the distance between the end of the limiting protrusion 191 away from the first wall 19 and the first wall 19 is a first distance D1, and the distance between the end of the first docking terminal 151 away from the first wall 19 and the first wall 19 is a second distance D2. The first distance D1 is not less than the second distance D2. The limiting protrusion 191 in this example can be used to block foreign objects outside the power supply module 15, so that when external foreign objects approach the power supply module 15, they are first blocked by the limiting protrusion 191, reducing the direct collision of foreign objects with the first docking terminal 151, thereby reducing the possibility of deformation of the first docking terminal 151.

[0247] The electric control board 152 can be connected to the bottom wall 1934, and the first docking terminal 151 can be extended away from the bottom wall 1934 so that the first docking terminal 151 can protrude from the outside of the electric control board 152. When the wet cleaner 20 is installed on the base 10, the second docking terminal 261 can connect with the first docking terminal 151 to form an electrical connection. In some examples, the electric control board 152 is located on the side of the bottom wall 1934 facing away from the side wall 1935. The bottom wall 1934 is provided with a first socket 1931. The first docking terminal 151 passes through the first socket 1931 and protrudes from the side of the bottom wall 1934 facing away from the electric control board 152. The first docking terminal 151 is blocked outside the electric control board 152 by the bottom wall 1934 to prevent dust or foreign matter from entering the electric control board 152. In some examples, one of the bottom wall 1934 and the electric control board 152 is provided with a positioning column 194, and the other is provided with a positioning hole 153. The positioning column 194 is embedded in the positioning hole 153, and the electric control board 152 and the bottom wall 1934 are positioned and fixed by the positioning column 194 and the positioning hole 153.

[0248] In some examples, the sidewall 1935 has a first surface 1933, and the limiting protrusion 191 is sealedly connected to the first surface 1933. The first surface 1933 is one of the surfaces of the sidewall 1935. Optionally, the first surface 1933 can be the end surface of the sidewall 1935 away from the bottom wall 1934. The sealing connection between the first surface 1933 and the limiting protrusion 191 means that a seal is formed at the junction of the first surface 1933 and the limiting protrusion 191. In this example, the sealing connection can be that the first surface 1933 and the limiting protrusion 191 are tightly fitted to form a seal, or the first surface 1933 and the limiting protrusion 191 are sealed via an intermediate connector 294. In this example, by sealingly connecting the sidewall 1935 and the limiting protrusion 191, foreign matter can be prevented from entering the interior of the base 10 through the gap between the limiting protrusion 191 and the sidewall 1935.

[0249] In some examples, the position-limiting protrusion 191 is provided with a first sealing portion 1911, and the first surface 1933 is provided with a second sealing portion 1932. The first sealing portion 1911 and the second sealing portion 1932 are sealedly connected, and the first sealing portion 1911 and the second sealing portion 1932 are respectively arranged around the bottom wall 1934. The first sealing portion 1911 and the second sealing portion 1932 cooperate with each other to seal the gap between the position-limiting protrusion 191 and the first surface 1933. In this example, the first sealing portion 1911 and the second sealing portion 1932 can be tightly fitted to form a seal. Optionally, at least one of the first sealing portion 1911 and the second sealing portion 1932 can be a sealing ring, and the seal is achieved through elastic deformation of at least one of the first sealing portion 1911 and the second sealing portion 1932.

[0250] In some examples, the end of the limiting protrusion 191 away from the first wall 19 is bent toward the first wall 19 to form the first sealing portion 1911. The first sealing portion 1911 can be integrally formed with the limiting protrusion 191. The first sealing portion 1911 can be a flange structure formed by bending the end of the limiting protrusion 191 away from the bottom wall 1934 inwardly to simplify the molding method of the first sealing portion 1911. Optionally, the limiting protrusion 191, the first sealing portion 1911, and the first wall 19 can be integrally formed.

[0251] In some examples, the second sealing portion 1932 is a groove opened on the first surface 1933, and the first sealing portion 1911 is sealedly connected to the inner wall surface of the groove; the groove opened on the first surface 1933 refers to a continuous or discontinuous groove recessed on the first surface 1933, and the groove forms the second sealing portion 1932.

[0252] In some examples, second sealing portion 1932 is a rib protruding from first surface 1933, and first sealing portion 1911 is sealingly connected to the outer surface of second sealing portion 1932. In this example, the rib forming second sealing portion 1932 can tightly fit with first sealing portion 1911 to form a mechanical seal. Optionally, there can be multiple ribs, with adjacent ribs arranged inside and outside, forming grooves between adjacent ribs. First sealing portion 1911 can be embedded in the grooves formed between adjacent ribs to form a seal between first sealing portion 1911 and second sealing portion 1932.

[0253] See also Figures 43 to 47 In some examples, the second power module 26 includes a main control board 28 and a second docking terminal 261 electrically connected to the main control board 28. The second docking terminal 261 can be used to electrically connect to an external power supply device for power supply. In some examples, the wet cleaner 20 also includes an energy storage battery electrically connected to the main control board 28.

[0254] In some examples, the second power module 26 further includes a docking base 262, which can be connected to the main control board 28. The docking base 262 can be used to support and fix the second docking terminal 261 so that the second docking terminal 261 maintains a preset state at a preset position on the outside of the main control board 28. In some examples, a second socket 263 is provided on the second docking terminal 261. The second socket 263 can be a through hole that passes through the docking base 262. The end of the second docking terminal 261 away from the main control board 28 can be accommodated in the second socket 263. The second socket 263 can be used to limit the second docking terminal 261 on the one hand to prevent the second docking terminal 261 from being excessively deformed and causing failure. On the other hand, the second socket 263 can protect the second docking terminal 261 to prevent external foreign objects from damaging the second docking terminal 261. On the other hand, when the second docking terminal 261 is adapted to the external power supply device, the second socket 263 can be used to limit and initially position the external power supply device so that the external power supply device can be more easily aligned and adapted to the second docking terminal 261; on the other hand, since the second socket 263 can limit the deformation range of the second docking terminal 261, when the external power supply device and the second docking terminal 261 contact each other, the second docking terminal 261 can always cooperate with the external power supply device, reducing the circuit breakage between the second docking terminal 261 and the external power supply device.

[0255] In some examples, when the wet cleaner 20 is mounted on the base 10, the limiting protrusion 191 is disposed around the periphery of the docking base 262. The limiting protrusion 191 can block the outer periphery of the docking base 262, thereby forming an annular sealing structure around the outer periphery of the docking base 262. The limiting protrusion 191 can be used to prevent foreign matter from entering the interior of the docking base 262 through the outer periphery of the docking base 262. In some examples, when the wet cleaner 20 is mounted on the base 10, the end of the docking base 262 away from the main control board 28 can abut against the side wall 1935 of the bracket 193, thereby enabling a sealed connection between the docking base 262 and the side wall 1935 of the bracket 193, thereby sealing the connection between the first docking terminal 151 and the second docking terminal 261.

[0256] The distance between the end surface of the docking base 262 facing away from the main control board 28 and the main control board 28 is a third distance D3, and the distance between the end surface of the second wall 27 facing away from the main control board 28 and the main control board 28 is a fourth distance D4. The third distance D3 is not greater than the fourth distance D4. In this example, the docking base 262 can be stored inside the retaining groove 271. The end of the docking base 262 facing away from the main control board 28 does not protrude outside the second wall 27. When foreign objects approach the retaining groove 271, the second wall 27 can block the foreign objects, thereby reducing the possibility of the foreign objects directly colliding with the docking base 262.

[0257] In some examples, the wet cleaner 20 includes an electrical control box 281 as described in any of the above examples. An electrical compartment 2813 is formed within the electrical control box 281. The electrical compartment 2813 can be used to accommodate the main control board 28. Optionally, a storage battery can also be installed within the electrical compartment 2813. Optionally, the electrical control box 281 includes a first housing 2811 and a second housing 2812 connected to the first housing 2811.
