Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning device. Background Technology

[0002] The cleaning robot and the base station are used together as a cleaning device. After the cleaning robot has been used for a period of time, its wastewater tank is full, and the robot returns to the base station to perform cleaning and wastewater discharge operations. The wastewater inside the cleaning robot, as well as the wastewater from cleaning the robot within the base station (e.g., cleaning the roller brushes), needs to be discharged into the base station's wastewater tank. In related technologies, the drainage system in the base station is complex in design and tends to occupy a large amount of space in the cleaning equipment, resulting in a large size of the cleaning equipment. Utility Model Content

[0003] This application provides a cleaning device that can use a multi-way valve to realize a sewage discharge system that can separately recycle sewage from the cleaning host and the sewage tray, thereby reducing the volume occupied by the sewage discharge system in the cleaning device.

[0004] This application provides a cleaning device, including:

[0005] The cleaning unit has a first drain outlet;

[0006] The base station includes a wastewater tray with a second drain outlet, and the base station is used for maintaining the cleaning host.

[0007] A wastewater tank is installed at the base station;

[0008] A multi-way valve is disposed in the base station. The multi-way valve has independent first and second chambers. The multi-way valve is provided with a first opening, a second opening, a third opening, and a fourth opening. The first opening communicates with the third opening through the first chamber, and the second opening communicates with the fourth opening through the second chamber.

[0009] A switching component is disposed within the multi-way valve, and the switching component is movable relative to the multi-way valve to realize the connection and disconnection between the first opening member and the first cavity, and to realize the connection and disconnection between the second opening member and the second cavity;

[0010] The wastewater tray is connected to the first opening via the second drain outlet, the cleaning unit is connected to the second opening via the first drain outlet, the wastewater tank is connected to both the third and fourth openings, and the cleaning equipment has a first working state of recycling wastewater from the wastewater tray to the wastewater tank, and a second working state of recycling wastewater from the cleaning unit to the wastewater tank.

[0011] Based on the cleaning equipment in this embodiment, this embodiment can achieve a single sewage discharge system using a multi-way valve to separately recover sewage from the cleaning unit and the sewage tray. Furthermore, the first and second chambers of the multi-way valve are independently configured, allowing the sewage from the cleaning unit and the sewage tray to be discharged independently. In other words, this embodiment achieves independent sewage discharge from both the cleaning unit and the sewage tray through a single multi-way valve, thereby reducing the space and cost occupied by the sewage discharge system in the cleaning equipment. Simultaneously, the technical solution in this embodiment does not cause excessive noise or secondary pollution when discharging sewage from the cleaning unit and the sewage tray.

[0027] L1, First Direction. Detailed Implementation

[0028] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] After use, the cleaning robot carries wastewater inside. Upon returning to the base station, it cleans its roller brush, and any remaining wastewater enters the base station's tray. Both the wastewater from the robot and the wastewater in the tray need to be discharged into the base station's wastewater tank for centralized cleaning. In related technologies, because a single drainage system can only pump water from one path, multiple drainage systems are often installed in the base station for wastewater extraction. However, multiple drainage systems not only increase costs but also occupy significant space in the cleaning equipment, resulting in a larger overall size. Furthermore, using high-powered fans for wastewater extraction can cause considerable noise and secondary air pollution.

[0030] For the above situation, please refer to Figures 1-4 This application proposes a cleaning device 2, which includes a base station 40, a cleaning host 50, a wastewater tank 60, a multi-way valve 1, and a switching component 20. The base station 40 includes a wastewater tray (not shown in the figure) with a second drain outlet. The cleaning host 50 has a first drain outlet (not shown in the figure). The base station 40 is used to interface with the cleaning host 50 and to maintain it. For example, the base station 40 can charge the cleaning host 50 and can also be used to clean the cleaning host 50. The wastewater tank 60 and the multi-way valve 1 are both located in the base station 40. The multi-way valve 1 has independent first chambers 11 and second chambers 12. Figure 3 As shown, the multi-way valve 1 is provided with a first opening 14, a second opening 15, a third opening 16 and a fourth opening 17. The third opening 16 is connected to the first opening 14 through the first cavity 11, and the fourth opening 14 is connected to the second opening 15 through the second cavity 12.

[0031] The switching component 20 is disposed within the multi-way valve 1 and is movable relative to the multi-way valve 1 to switch the connection between the first opening 14 and the first cavity 11, and to switch the connection between the second opening 15 and the second cavity 12. The wastewater tray is connected to the first opening 14 via the second drain outlet, and the cleaning unit 50 is connected to the second opening 15 via the first drain outlet. The wastewater tank 60 is connected to both the third opening 16 and the fourth opening 17. In other words, the wastewater tray can discharge wastewater into the wastewater tank 60 via the multi-way valve 1, and the cleaning unit 50 can also discharge wastewater into the wastewater tank 60 via the multi-way valve 1. The cleaning device 2 has a first operating state of recovering wastewater from the wastewater tray into the wastewater tank 60, and a second operating state of recovering wastewater from the cleaning unit 50 into the wastewater tank 60.

[0032] Specifically, the first cavity 11 and the second cavity 12 are two independently configured cavities, each connected to two openings, one of which is an inlet and the other is an outlet. In the following description, the first opening 14 is used as the inlet of the first cavity 11, the second opening 15 as the inlet of the second cavity 12, the third opening 16 as the outlet of the first cavity 11, and the fourth opening 17 as the outlet of the second cavity 12. In this embodiment, the multi-way valve 1 can be a three-way valve. Of course, depending on actual needs, the multi-way valve 1 can also be a four-way valve, a five-way valve, or more.

[0033] It should be noted that the cleaning host 50 contains the first wastewater generated during the cleaning process, and the wastewater tray is used to collect the second wastewater generated by the cleaning host 50 in the base station 40. The wastewater tank 60 is connected to both the wastewater tray and the cleaning host 50 via a multi-way valve 1. This allows the first wastewater in the cleaning host 50 to flow through the multi-way valve 1 into the wastewater tank 60, and the second wastewater in the wastewater tray can also flow through the multi-way valve 1 into the wastewater tank 60. Therefore, the multi-way valve 1 and the switching component 20 together constitute a key part of the sewage discharge system in the cleaning equipment 2. The sewage discharge system refers to the system used by the cleaning equipment. In embodiment 2, the wastewater discharge channel can be implemented using a multi-way valve 1 to achieve a single wastewater discharge system that separately recovers wastewater from the cleaning unit 50 and the wastewater tray. Furthermore, the first chamber 11 and the second chamber 12 of the multi-way valve 1 are independently configured, allowing the wastewater from the cleaning unit 50 and the wastewater tray to be discharged independently. This means that this embodiment achieves independent wastewater discharge from both the cleaning unit 50 and the wastewater tray through a single multi-way valve 1, thereby reducing the volume and cost of the wastewater discharge system in the cleaning equipment 2 and saving a significant amount of space. Simultaneously, the technical solution in this embodiment does not generate excessive noise or secondary pollution when discharging wastewater from the cleaning unit 50 and the wastewater tray.

[0034] For example, the cleaning host 50 is a robotic vacuum cleaner. The cleaning host 50 can move relative to the base station 40. The cleaning host 50 has a mop and a roller brush. After the cleaning host 50 finishes cleaning the floor and returns to the base station 40, it will carry the first wastewater generated after cleaning. The base station 40 will rinse the mop and roller brush on the cleaning host 50. The second wastewater generated after rinsing will be stored in the wastewater tray of the base station 40. At this time, the drainage process of the cleaning device 2 is as follows: After the cleaning host 50 finishes cleaning the floor and returns to the base station 40, the multi-way valve 1 first opens the second opening 15 and closes the first opening 14. The first wastewater stored in the cleaning host 50 is discharged into the wastewater tank 60 through the first drain outlet and the second opening 15. During the discharge of the first wastewater, the base station 40 washes the mop and roller brush on the cleaning host 50. After the first wastewater is discharged, the cleaning in the base station 40 is also completed. The resulting second wastewater is stored in the wastewater tray. The multi-way valve 1 opens the first opening 14 and closes the second opening 15. The second wastewater stored in the wastewater tray is discharged into the wastewater tank 60 through the second drain and the first opening 14. This allows the cleaning work to be carried out simultaneously in the base station 40 when the cleaning host 50 is discharging wastewater. After the wastewater discharge in the cleaning host 50 is completed, the cleaning in the base station 40 is completed, and the wastewater generated during cleaning can be discharged. In other words, the wastewater in the cleaning host 50 and the base station 40 can be discharged alternately.

[0035] Please see Figures 1-2In some embodiments of this application, the cleaning device 2 further includes a connecting pipe 30, which has a first channel 31, a second channel 32 and a third channel 33. The first channel 31 connects to the third opening 16 and the third channel 33, the second channel 32 connects to the fourth opening 17 and the third channel 33, and the third channel 33 connects to the sewage tank 60. That is, the sewage tank 60 is connected to the third opening 16 and the fourth opening 17 through the connecting pipe 30, and the outlet of the third channel 33 is connected to the sewage tank 60. The first sewage in the cleaning host can be discharged into the sewage tank 60 in sequence through the first drain outlet, the second opening 15, the fourth opening 17, the second channel 32 and the third channel 33. The second sewage in the sewage tray can be discharged into the sewage tank 60 in sequence through the second drain outlet, the first opening 14, the third opening 16, the first channel 31 and the third channel 33.

[0036] It is easy to understand that if the first opening 14 and the second opening 15 are opened one at a time, the multiple chambers in the multi-way valve 1 can alternately perform drainage operations. The sewage flowing out of the third opening 16 can flow from the first channel 31 to the third channel 33, and the sewage flowing out of the fourth opening 17 can also flow from the second channel 32 to the third channel 33. The third channel 33 is connected to the sewage tank. That is, one multi-way valve 1 can discharge sewage from multiple different locations to the same location, so that the cleaning unit and the sewage tray can drain water to the sewage tank through one multi-way valve 1.

[0037] In some embodiments, the cleaning device 2 further includes an air pump 70, which has an air intake port connected to a wastewater tank 60. The air pump 70 draws air from the wastewater tank 60 through the air intake port, creating a negative pressure state in the wastewater tank 60, thereby collecting wastewater from the cleaning unit or wastewater tray into the wastewater tank 60. The air intake port is connected to the top of the wastewater tank 60, allowing the air pump 70 to better draw air from the wastewater tank 60. Furthermore, the third channel 33 of the connecting pipe 30 can also be connected to the top of the wastewater tank 60.

[0038] Please see Figures 4-5 In some embodiments of this application, the switching component 20 includes a blocking member 21, which is movable relative to the multi-way valve 1. The blocking member 21 includes a first end 211 located in the first cavity 11 and a second end 212 located in the second cavity 12, so as to realize the connection and disconnection between the first opening member 14 and the first cavity 11 through the first end 211 of the blocking member 21, and to realize the connection and disconnection between the second opening member 15 and the second cavity 12 through the second end 212 of the blocking member 21.

[0039] Specifically, such as Figures 4-5As shown, when the cleaning device 2 is in the first working state, the second end 212 of the blocking member 21 closes the second opening member 15, that is, the second opening member 15 and the second cavity 12 are cut off by the second end 212 of the blocking member 21, and the sewage outside the second opening member 15 cannot flow into the second cavity 12. At this time, the first end 211 of the blocking member 21 does not close the first opening member 14, and the first opening member 14 and the first cavity 11 are in a conductive state. The second drain, the first opening member 14, the third opening member 16 and the sewage tank 60 are connected in sequence. The sewage in the sewage tray can flow from the second drain to the first opening member 14, the first cavity 11 and the third opening member 16 in sequence until the sewage enters the sewage tank 60. Similarly, when the cleaning device 2 is in its second operating state, the first end 211 of the blocking member 21 closes the first opening 14, that is, the connection between the first opening 14 and the first cavity 11 is cut off by the first end 211 of the blocking member 21, and the sewage outside the first opening 14 cannot flow into the first cavity 11. At this time, the second end 212 of the blocking member 21 does not close the second opening 15, and the second opening 15 and the second cavity 12 are in a conductive state. The first drain outlet, the second opening 15, the fourth opening 17 and the sewage tank 60 are connected in sequence, and the sewage in the cleaning host 50 can flow from the first drain outlet to the second opening 15, the second cavity 12 and the fourth opening 17 in sequence until the sewage enters the sewage tank 60. It can be understood that the first cavity 11 and the second cavity 12 in the multi-way valve 1 can perform drainage operations alternately; or, in some other embodiments, the first cavity 11 and the second cavity 12 can also perform drainage operations simultaneously, which is not specifically limited here.

[0040] It should be noted that, in this embodiment of the application, by setting up independent first chambers 11 and second chambers 12, and setting independent inlets and outlets, the first chamber 11 can receive sewage from the sewage tray, and the second chamber 12 can receive sewage from the cleaning host 50. Thus, the sewage tray and the cleaning host 50 can be recycled by a single sewage discharge system through a multi-way valve 1. This can save the space occupied by the sewage discharge system in the cleaning equipment 2 and save the production cost of the sewage discharge system.

[0041] Furthermore, the multi-way valve 1 is provided with a drive assembly 22, which is connected to the blocking member 21. The drive assembly 22 provides power for the movement of the blocking member 21, thereby driving the blocking member 21 to move relative to the multi-way valve 1. In this embodiment, the type of drive assembly 22 is not specifically limited.

[0042] In some embodiments of this application, the first opening member 14 and the second opening member 15 are spaced apart on the multi-way valve 1 along the first direction L1. That is, there is a gap between the position of the first opening member 14 on the multi-way valve 1 and the position of the second opening member 15 on the multi-way valve 1. Specifically, the first opening member 14 and the second opening member 15 can be spaced apart on the same side of the multi-way valve 1. The blocking member 21 moves along the first direction L1. When the blocking member 21 cuts off the first opening member 14 and the first cavity 11, the peripheral sidewall of the first end 211 of the blocking member 21 abuts against the first opening member 14. When the blocking member 21 cuts off the second opening member 15 and the second cavity 12, the peripheral sidewall of the second end 212 of the blocking member 21 abuts against the second opening member 15.

[0043] Alternatively, the first opening member 14 and the second opening member 15 are respectively disposed at opposite ends of the multi-way valve 1 along the first direction L1. In this case, the first end 211 is provided with a first switching part 213 on the side facing the first opening member 14, and the second end 212 is provided with a second switching part 214 on the side facing the second opening member 15, so that when the blocking member 21 moves along the first direction L1, the first switching part 213 on the blocking member 21 can close and open the first opening member 14, and the second switching part 214 on the blocking member 21 can close and open the second opening member 15.

[0044] Please see Figure 5 In some embodiments of this application, the drive assembly 22 includes a drive member 221 and a transmission member 222. The drive member 221 is rotatably connected to the multi-way valve 1, and the transmission member 222 is disposed on the blocking member 21. The drive member 221 and the transmission member 222 cooperate to convert the rotational motion of the drive member 221 into the linear motion of the blocking member 21 along the first direction L1.

[0045] Specifically, the drive member 221 provides power to the blocking member 21 by rotating, and the rotation of the drive member 221 has no displacement stroke, so the installation space required for the drive member 221 can be reduced. The transmission member 222 converts the rotational motion of the drive member 221 into linear motion, and the blocking member can achieve the purpose of closing different openings on the multi-way valve 1 during the linear motion.

[0046] In some embodiments, such as Figure 5 As shown, the drive assembly 22 can be a gear and rack mechanism. For example, the drive member 221 is a gear, and the transmission member 222 is a rack. The gear and rack mesh to drive the blocking member to move linearly relative to the multi-way valve 1 along the first direction L1. The drive assembly 22 also includes a drive motor 223 mounted on the multi-way valve 1, which drives the gear to rotate. Alternatively, the drive assembly 22 can also be a crank-rocker mechanism, a slider-connecting rod mechanism, etc.

[0047] Please see Figures 4-5The multi-way valve 1 also has a third cavity 13, which is spaced apart from the first cavity 11 and the second cavity 12. At least a portion of the blocking member 21 is located within the third cavity 13. The first end 211 of the blocking member 21 extends from the third cavity 13 to the first cavity 11, and the second end 212 of the blocking member 21 extends from the third cavity 13 to the second cavity 12. Preferably, the first cavity 11 and the second cavity 12 are located on opposite sides of the third cavity 13, and both ends of the blocking member 21 penetrate the third cavity 13 and extend into the first cavity 11 and the second cavity 12, respectively.

[0048] Specifically, at least a portion of the drive assembly 22 is disposed within the third cavity 13 to facilitate the movement of the drive blocking member 21. The third cavity 13 is configured to provide installation space for the switching assembly 20 and to protect the switching assembly 20, thereby reducing the movement of the switching assembly 20 under external interference.

[0049] Further, please see Figures 5-6 In some embodiments of this application, the multi-way valve 1 further has a first through hole 18 and a second through hole 19 through which the blocking member 21 passes. The third cavity 13 is connected to the first cavity 11 through the first through hole 18 and to the second cavity 12 through the second through hole 19. The first end 211 passes through the first through hole 18 and extends into the first cavity 11, and the second end 212 passes through the second through hole 19 and extends into the second cavity 12.

[0050] like Figures 5-7 As shown, the switching assembly 20 also includes a first elastic seal 23, which is located inside the first cavity 11. The first elastic seal 23 is sealed to the inner wall of the first cavity 11, and forms a first sealing cavity 25 with the first elastic seal 23 and a portion of the inner wall of the first cavity. The first through hole 18 communicates with the first sealing cavity 25, allowing the first end 211 of the blocking member 21 to extend into the first sealing cavity 25. In other words, the first elastic seal 23 can be fitted onto the first end 211, and the first elastic seal 23 is sealed to a portion of the inner wall of the first cavity 11, so that after the first end 211 of the blocking member 21 extends into the first sealing cavity 25, the first elastic seal 23 isolates the first end 211 of the blocking member 21 from the first cavity 11.

[0051] Specifically, such as Figure 5As shown, the first cavity 11 has a first sidewall 111 and a second sidewall 112 arranged opposite to each other along a first direction L1. A first through hole 18 is located on the first sidewall 111, and a first opening member 14 is located on the second sidewall 112. A first elastic sealing member 23 is sleeved on the first end 211, and the end of the first elastic sealing member 23 is sealed to the first sidewall 111 of the first cavity 11. Thus, the first elastic sealing member 23 and the first sidewall 111 together form a first sealed cavity 25. The first sealed cavity 25 is not connected to the first cavity 11. The first end 211 of the blocking member 21 passes through the first through hole 18 into the first sealed cavity 25. The first elastic sealing member 23 separates the first end 211 from the first cavity 11, providing sealing protection for the first end 211. This not only prevents sewage in the first cavity 11 from contacting the first end 211, but also prevents sewage in the first cavity 11 from leaking through the first through hole 18.

[0052] like Figure 5 and Figure 8 As shown, the switching assembly 20 also includes a second elastic seal 24, which is located in the second cavity 12. The second elastic seal 24 is sealed to the inner wall of the second cavity 12 and forms a second sealing cavity 26. The second through hole 19 communicates with the second sealing cavity 26 so that the second end 212 of the blocking member 21 extends into the second sealing cavity 26. That is, the second elastic seal 24 can be sleeved on the second end 212, and the second elastic seal 24 is sealed to a portion of the inner wall of the second cavity 12 so that after the second end 212 of the blocking member 21 extends into the second sealing cavity 26, the second elastic seal 24 isolates the second end 212 of the blocking member 21 from the second cavity 12.

[0053] Similarly, it can be seen that, as Figure 5 As shown, the inner wall of the second cavity 12 includes a third sidewall 121 and a fourth sidewall 122 disposed opposite to each other along the first direction L1. The second through hole 19 is located on the third sidewall 121, the second opening 15 is located on the fourth sidewall 122, and the second elastic sealing member 24 and the third sidewall 121 together form a second sealing cavity 26 (as shown). Figure 8 As shown, there is no communication between the second sealing cavity 26 and the second cavity 12. The second end 212 of the blocking member 21 passes through the second through hole 19 into the second sealing cavity 26. The second elastic sealing member 26 separates the second end 212 from the second cavity 12. The second elastic sealing member 24 can provide sealing protection for the second end 212, which can not only prevent the sewage in the second cavity 12 from contacting the second end 212, but also prevent the sewage in the second cavity 12 from leaking from the second through hole 19.

[0054] It should be noted that, since the blocking member 21 moves along the first direction L1, the first end 211 will extend and retract within the first cavity 11, and the second end 212 will extend and retract within the second cavity 12. The first elastic seal 23 and the second elastic seal 24 are elastic. The side of the first elastic seal 23 away from the first through hole 18 can be connected to the first end 211, and the side of the second elastic seal 24 away from the second through hole 19 can be connected to the second end 212. This allows the first elastic seal 23 and the second elastic seal 24 to fold as the first end 211 and the second end 212 move. For example, both the first elastic seal 23 and the second elastic seal 24 can be corrugated tubes made of silicone or plastic material, which are easy to fold and extend along the first direction L1.

[0055] Further, please see Figure 7 In some embodiments of this application, the first elastic seal 23 includes a first main body 231 and a first sealing ring 232 disposed on the periphery of the first main body 231. The first sealing ring 232 is sleeved on the first main body 231. The inner ring of the first sealing ring 232 is sealed to the first main body 231. The outer ring of the first sealing ring 232 abuts against the inner sidewall of the first cavity 11. The first opening 14 and the third opening 16 are both located on the same side of the first sealing ring 232.

[0056] Specifically, the periphery of the first main body 231 refers to the extension around the outer surface of the first main body 231. That is, the first sealing ring 232 is sleeved on the outer surface of the first main body 231. During the movement of the blocking member 21 relative to the multi-way valve, the outer ring of the first sealing ring 232 is always in contact with the inner wall of the first cavity 11. In other words, sewage entering the first cavity 11 from the first opening member 14 cannot pass through the first sealing ring 232. That is, the first sealing ring 232 can prevent sewage in the first cavity 11 from approaching the first side wall 111. Meanwhile, the first opening 14 (i.e., the water inlet) is positioned opposite the first end 211 of the blocking member 21, and the first opening 14 and the third opening 16 (i.e., the water outlet) are located on the same side of the first sealing ring 232. Therefore, the third opening 16 is located between the first opening 14 and the first sealing ring 232, meaning that the position of the third opening 16 is closer to the first sealing ring 232 than the position of the first opening 14. As a result, during the reciprocating motion of the blocking member 21 along the first direction L1, the first sealing ring 232 can push the sewage and dirt adhering to the inner wall of the first cavity 11 toward the third opening 16, thereby keeping the inner wall of the first cavity 11 clean. Multiple first sealing rings can be provided around the periphery of the first main body 231, and these multiple first sealing rings are arranged at intervals along the first direction L1 to further improve the sealing performance.

[0057] like Figure 8As shown, the second elastic seal 24 includes a second main body 241 and a second sealing ring 242 disposed around the second main body 241. The second sealing ring 242 is sleeved on the second main body 241. The inner ring of the second sealing ring 242 is sealed to the second main body 241. The outer ring of the second sealing ring 242 abuts against the inner wall of the second cavity 12. The second opening 15 and the fourth opening 17 are both located on the same side of the second sealing ring 242.

[0058] Similarly, the periphery of the second main body 241 refers to the area extending around the outer surface of the second main body 241. That is, the first sealing ring 232 is fitted onto the outer surface of the second main body 241, and the second through hole 19 is located on the third side wall 121. The second sealing ring 242 can prevent sewage in the second cavity 12 from approaching the third side wall 121. The second opening 15 is located on the fourth side wall 122, and the second opening 15 and the fourth opening 17 are located on the same side of the second sealing ring 242. Therefore, the fourth opening 17 is located between the second opening 15 and the second sealing ring 242. During the reciprocating movement of the blocking member 21 along the first direction L1, the second sealing ring 242 can also push the sewage and dirt adhering to the inner side wall of the second cavity 12 toward the fourth opening 17, thereby keeping the inner side wall of the second cavity 12 clean. Multiple second sealing rings can also be provided on the periphery of the second main body 241, and these multiple second sealing rings are arranged at intervals along the first direction L1 to further improve the sealing performance.

[0059] Please see Figure 7 In some embodiments of this application, the first end 211 of the blocking member 21 has an arc-shaped first protrusion 215 on the side facing the first opening member 14. The first protrusion 215 is used to abut against a portion of the opening wall of the first opening member 14, and at least a portion of the first protrusion 215 extends into the first opening member 14. It is easy to understand that when the first end 211 closes the first opening member 14, the first protrusion 215 blocks the first opening member 14, the surface of the first protrusion 215 seals against the opening wall of the first opening member 14, and a portion of the first protrusion 215 extends into the first opening member 14, thereby forming a seal between the first end 211 and the first opening member 14.

[0060] like Figure 8As shown, the second end 212 of the blocking member 21 has an arc-shaped second protrusion 216 on the side facing the second opening member 15. The second protrusion 216 abuts against a portion of the opening wall of the second opening member 15, and at least a portion of the second protrusion 216 extends into the second opening member 15. Similarly, when the second end 212 closes the second opening member 15, the second protrusion 216 blocks the second opening member 15, the surface of the second protrusion 216 seals against the opening wall of the second opening member 15, and a portion of the second protrusion 216 extends into the second opening member 15, thereby forming a seal between the second end and the second opening member 15. Both the first protrusion 215 and the second protrusion 216 can be made of soft rubber material, which facilitates the sealing between the blocking member 21 and the opening member.

[0061] Please see Figure 7 In some embodiments of this application, a first sealing strip 217 is provided on the first end 211 of the blocking member 21. When the cleaning device is in a second working state, the first end 211 of the blocking member 21 seals the first opening member 14, and the first sealing strip 217 abuts against the inner sidewall of the first cavity 11. Specifically, the inner sidewall of the first cavity 11 includes a second sidewall 112, the first opening member 14 is located on the second sidewall 112, and the first sealing strip 217 abuts against the second sidewall 112, thereby improving the sealing performance between the first end 211 of the blocking member 21 and the first opening member 14.

[0062] like Figure 8 As shown, a second sealing strip 218 is provided on the second end 212 of the blocking member 21. When the cleaning equipment is in the first working state, the second end 212 of the blocking member 21 seals the second opening member 15, and the second sealing strip 218 abuts against the inner sidewall of the second cavity 12. Specifically, the inner sidewall of the second cavity 12 includes a fourth sidewall 122, the second opening member 15 is located on the fourth sidewall 122, and the second sealing strip 218 abuts against the fourth sidewall 122, thereby improving the sealing performance between the second end 212 of the blocking member 21 and the second opening member 15.

[0063] In some embodiments, one or more of the first sealing strip 217 and the second sealing strip 218 can be provided. Taking the example of multiple first sealing strips 217, multiple sealing strips are perpendicular to and abut against the second sidewall 112. The compression between the sealing strips and the second sidewall 112 forms multiple seals on the second opening member 15, thereby further improving the sealing performance between the first end 211 of the blocking member 21 and the first opening member 14.
