[0055] Refer to FIG. 1 , which shows a schematic diagram of the structure of a cleaning device in an embodiment of the present application. The cleaning device provided in an embodiment of the present application includes a cleaning device 100 and a base station 200. The cleaning device 100 is used to perform the cleaning needs required by the user, such as sweeping or mopping the floor. In addition, the cleaning device 100 also has a self-cleaning function. After mopping the floor for a period of time, the cleaning device 100 can clean its own cleaning parts such as a mop and a roller brush, and the sewage after cleaning will be temporarily stored in a sewage tank inside the cleaning device 100.

[0056] 2, 3 and 4, the cleaning device 100 includes a cleaning body 110 and a switch 130. The cleaning body 110 can enter or leave the base station 200 along the first direction X. After the cleaning body 110 enters the base station 200, the base station 200 can perform operations such as water replenishment, charging, and cleaning on the cleaning body 110. In addition, a sewage tank and a drainage hole 111 connected to the sewage tank are provided on the cleaning body 110. The switch 130 is movably mounted on the cleaning body 110. The switch 130 has a first position and a second position during the movement. When the switch 130 moves to the first position, the switch 130 closes the drainage hole 111, and when the switch 130 moves to the second position, the switch 130 opens the drainage hole 111.

[0057] A push rod 210 is protruding from the surface of the base station 200. When the cleaning body 110 enters the base station 200 along the first direction X, the push rod 210 can abut against the switch member 130, and as the cleaning body 110 continues to enter the base station 200, the push rod 210 can push the switch member 130 to move to the second position. That is, when the cleaning body 110 enters the base station 200, the push rod 210 can push the switch member 130 to move, thereby opening the drainage hole 111, and the sewage in the cleaning body 110 can enter the base station 200 through the drainage hole 111, and finally be centrally processed in the base station 200. Optionally, a shock absorbing member 250 is sleeved on the push rod 210, and the shock absorbing member 250 can reduce the impact force generated by the contact between the push rod 210 and the switch member 130, so as to increase the service life of the push rod 210 and the switch member 130.

[0058] After the sewage in the cleaning body 110 is emptied, if there is no need to charge or refill the cleaning body 110, the cleaning body 110 can leave the base station 200 along the first direction X to continue cleaning. While the cleaning body 110 is leaving the base station 200 along the first direction X, the switch 130 is separated from the top rod 210 and can move to the first position under the action of external force. That is, after the cleaning body 110 leaves the base station 200, the switch 130 can close the drainage hole 111 to prevent sewage from flowing out of the drainage hole when the cleaning device 100 continues to use the self-cleaning function.

[0059] In the above-mentioned cleaning device 100, when the cleaning body 110 enters the base station 200, the push rod 210 can push the switch 130 to move, thereby realizing the automatic opening of the drainage hole 111, and the sewage in the cleaning body 110 can enter the base station 200 through the drainage hole 111. When the cleaning body 110 leaves the base station 200, the push rod 210 can close the drainage hole 111 under the action of external force, so that the cleaning body 110 can continue to be temporarily stored inside the cleaning device 100 after leaving the base station 200, and be discharged into the base station 200 when it returns to the base station 200 next time. In this way, the cleaning body 110 can realize automatic sewage discharge during the process of entering and leaving the base station 200, so that the sewage generated by the cleaning device 100 each time can be centrally processed at the base station 200, thereby reducing the number of times the user cleans the sewage tank and improving the user experience.

[0060] It should be noted that the switch member 130 can move to the first position under the action of an external force, which means that a driving force generated by a driving member such as a motor can be separately set to drive the switch member 130 from the second position to the first position. In some other embodiments, the external force can also be gravity. When the cleaning body 110 leaves the base station 200, the switch member 130 can move from the second position to the first position under the action of its own gravity because there is no abutment of the top rod 210, thereby realizing self-closing of the sewage outlet.

[0061] Among them, the way that the switch 130 closes the drain hole 111 can be by covering the drain hole 111 with the switch 130, but the cleaning body 110 is prone to vibration during the process of cleaning the floor, resulting in a loose cover between the switch 130 and the drain hole 111, thereby causing water leakage. To this end, in some embodiments of the present application, a blocking portion 134 is provided on the switch 130, and when the switch 130 moves to the first position, the blocking portion 134 is inserted into the drain hole 111, thereby completing the closing of the drain hole 111. When the switch 130 moves to the second position, the blocking portion 134 leaves the drain hole 111, thereby completing the opening of the drain hole 111.

[0062] That is, the drain hole 111 is closed by inserting the blocking portion 134 into the drain hole 111. Even if the switch 130 vibrates, the blocking portion 134 can reliably block the drain hole 111 and prevent sewage from leaking. Further, in order to improve the blocking effect of the drain hole 111, the cleaning device 100 further includes a sealing ring 135. When the blocking portion 134 is inserted into the drain hole 111, the sealing ring 135 is arranged between the blocking portion 134 and the inner wall of the drain hole 111.

[0063] Optionally, the sealing ring 135 is sleeved on the outer peripheral wall of the blocking portion 134 , and in some other embodiments, a sealing groove may be opened on the inner wall of the drain hole 111 , and the sealing ring 135 is arranged in the sealing groove.

[0064] During the process of inserting the blocking part 134 into the drain hole 111, the blocking part 134 needs to squeeze the sealing ring 135 so that the sealing ring 135 can seal the gap between the blocking part 134 and the drain hole 111. Therefore, a large external force is required to insert the blocking part 134 into the blocking hole. If the blocking hole is closed only by the deadweight of the switch component 130, the blocking will not be firm and water leakage will occur.

[0065] To this end, in some embodiments of the present application, the cleaning device 100 further includes a reset member 140, which is disposed on the cleaning body 110 and connected to the switch member 130. When the cleaning body 110 leaves the base station 200 along the first direction X, the reset member 140 drives the switch member 130 to move to the first position. The reset member 140 may be a motor, which applies sufficient external force to the switch member 130 so that the blocking portion 134 of the switch member 130 can be firmly inserted into the drain hole 111, thereby ensuring the blocking effect of the drain hole 111.

[0066] In some embodiments, the reset member 140 is an elastic member 141. When the switch member 130 moves from the first position to the second position, the elastic member 141 accumulates elastic force for driving the switch member 130 to move from the second position to the first position. In this way, the switch member 130 is pushed from the first position to the second position by the push rod 210. During this process, the elastic member 141 is stretched or compressed. After that, the cleaning body 110 leaves the base station 200. The switch member 130 is no longer abutted by the push rod 210. The elastic member 141 will restore its deformation, thereby pushing the switch member 130 from the second position to the first position. The external force applied by the elastic member 141 enables the blocking portion 134 of the switch member 130 to be firmly inserted into the drain hole 111.

[0067] Specifically in one embodiment, the switch member 130 includes a first end 131 and a second end 132 opposite to each other in its longitudinal direction. The switch member 130 is swingably mounted on the cleaning body 110 around a rotation axis. The rotation axis is located between the first end 131 and the second end 132, and the direction of the rotation axis intersects with the first direction X.

[0068] When the switch member 130 is located in the first position, the second end 132 closes the drain hole 111, and the elastic member 141 is arranged between the first end 131 and the cleaning body 110. When the cleaning body 110 enters the base station 200 along the first direction X, the push rod 210 can abut against the first end 131 and push the first end 131 close to the cleaning body 110. At this time, the switch member 130 rotates around the first circumferential direction, and the second end 132 of the switch member 130 will gradually move away from the drain hole 111, and finally the switch member 130 moves to the second position and opens the drain hole 111.

[0069] When the cleaning body 110 leaves the base station 200 along the first direction X, the elastic member 141 pushes the first end 131 away from the cleaning body 110, and the switch member 130 moves around the second circumferential direction opposite to the first circumferential direction, so that the second end 132 of the switch member 130 gradually approaches the drain hole 111, and finally the switch member 130 closes the drain hole 111. Further, the blocking portion 134 is disposed at the second end 132 of the switch member 130, and when the second end 132 of the switch member 130 gradually approaches the drain hole 111, the blocking portion 134 will gradually be inserted into the drain hole 111, and finally the blocking portion 134 will close the drain hole 111.

[0070] Specifically, referring to Figure 1, the switch member 130 is arranged on the cleaning body 110 in the vertical direction, and the first end 131 is located above the second end 132. When the cleaning body 110 enters the base station 200, the cleaning body 110 moves from right to left, and the top rod 210 abuts against the first end 131 of the switch member 130 and pushes the switch member 130 to rotate clockwise, the elastic member 141 is compressed, and the blocking portion 134 arranged at the second end 132 is separated from the drain hole 111, and the drain outlet is opened.

[0071] When the cleaning body 110 leaves the base station 200, the cleaning body 110 moves from left to right, the top rod 210 and the switch member 130 gradually separate, the elastic member 141 recovers its deformation and pushes the switch member 130 to rotate counterclockwise, and the blocking portion 134 gradually approaches the drain hole 111 until the blocking portion 134 closes the drain hole 111.

[0072] Further, a limiting hole 112 is provided on the cleaning body 110, a limiting post 133 is provided on the switch member 130 protruding toward one side of the cleaning body 110, and the elastic member 141 is a spring, one end of the spring is inserted into the limiting hole 112, and the other end of the spring is sleeved on the limiting post 133. Thus, the spring is fixed by the limiting hole 112 and the limiting post 133. It is understandable that in some other embodiments, the limiting hole 112 can be provided on the switch member 130, and the limiting post 133 can be provided on the cleaning body 110.

[0073] In some embodiments, in order to prevent the push rod 210 from pushing the switch member 130 too far, resulting in excessive compression of the elastic member 141 and affecting the recovery ability of the elastic member 141, an opening limit is provided on the cleaning body 110. When the cleaning body 110 enters the base station 200 along the first direction X, the switch member 130 can move to abut against the opening limit rib 153 under the action of the push rod (210), that is, the second position is the position where the switch member 130 abuts against the opening limit rib 153, thereby preventing the moving part of the switch member 130 from being too long.

[0074] Further, referring to Figure 6, the cleaning body 110 also includes a closing limit rib 154. When the cleaning body 110 leaves the base along the first direction X, the switch member 130 can move to abut against the closing limit rib 154 under the action of the elastic member 141 or other external force, that is, the first position is the position where the switch member 130 abuts against the closing limit rib 154, thereby preventing the blocking portion 134 from being excessively inserted into the sewage outlet, making it difficult to pull out the blocking portion 134.

[0075] In some embodiments of the present application, a sewage chamber 118 for storing sewage is provided on the cleaning body 110, and the sewage chamber 118 can be formed in a detachable sewage tank, or directly formed inside the cleaning body 110. When the cleaning device 100 is in use, the sewage discharge hole 111 is located at the lowest point of the sewage chamber 118 in the direction of gravity, so that the sewage in the sewage chamber 118 can be discharged from the sewage discharge hole 111 as much as possible under the action of gravity.

[0076] Furthermore, the bottom wall of the sewage chamber 118 is inclined relative to the direction of gravity, and the sewage hole 111 is located at the lowest point of the bottom of the sewage chamber 118 in the direction of gravity, so that the interior of the sewage chamber 118 is guided by the inclined bottom wall, so that the sewage in the sewage chamber 118 is gathered to the sewage hole 111 and finally discharged through the sewage hole 111.

[0077] In actual use, the cleaning body 110 is usually assembled from multiple parts. Due to manufacturing and assembly tolerances, there will be gaps between the parts. If the sewage enters the gaps between the parts during the sewage discharge hole 111, the sewage will drip from the gaps during the subsequent cleaning work of the cleaning body 110, causing ground pollution.

[0078] To this end, in some embodiments of the present application, referring to FIG. 5 and FIG. 6 , the cleaning body 110 is provided with a water guide channel 150, which is connected to the drain hole 111, and the sewage in the cleaning body 110 can flow into the base station 200 through the water guide channel 150. That is, the sewage discharged from the drain hole 111 is guided by the water guide channel 150, so that the sewage does not pass through or reduces the gaps between the components in the process of passing from the drain outlet to the base station 200, thereby reducing the accumulation of sewage in the gaps.

[0079] In some embodiments, the cleaning body 110 includes a housing 113 and a base 114, the housing 113 is mounted on the base 114, and a water channel 150 and a sewage discharge hole 111 are provided on the housing 113. An installation gap 115 is formed between the housing 113 and the base 114, and the housing 113 has a water outlet 151 connected to the water channel 150, and sewage flows out of the water channel 150 through the water outlet 151, and the water outlet 151 is located below the installation gap 115 in the direction of gravity. In this way, when the sewage is discharged from the water channel 150 through the water outlet 151, since the water outlet 151 is located below the installation gap 115, the sewage will not pass through the installation gap 115, thereby preventing the sewage from entering the installation gap 115.

[0080] Specifically, a mounting groove 152 is provided on the housing 113, and the drain hole 111 is provided on the inner wall of the mounting groove 152, and a water guide channel 150 is also formed in the mounting groove 152, that is, the sewage is guided through the two side walls of the mounting groove 152, and the mounting groove 152 is opened at one end in its longitudinal direction to form a water guide outlet 151. In this way, the sewage discharged from the drain hole 111 will enter the mounting groove 152, and under the action of the two side walls of the mounting groove 152, the sewage will move along the mounting groove 152 until it is discharged from one end of the mounting groove 152, that is, the water guide outlet 151, and enters the base station 200.

[0081] Furthermore, a clearance opening 116 is provided at the bottom of the base 114, a portion of the housing 113 extends into the clearance opening 116, the mounting groove 152 extends to the portion of the housing 113 extending into the clearance opening 116, and the water outlet 151 is located in the clearance opening 116. In this way, the sewage will be discharged directly from the bottom of the housing 113 without passing through the mounting gap 115 or the gaps of other parts on the cleaning body 110, effectively preventing the sewage from entering the gap and causing the sewage to contaminate the ground during the subsequent cleaning process of the cleaning body 110.

[0082] Furthermore, in order to prevent sewage from splashing outside the mounting groove 152 during discharge from the sewage hole 111, causing sewage to contaminate the housing 113, the base 114 or the base station 200, two water guide ribs 117 are protruding from the side wall of the housing 113, and the mounting groove 152 and the water outlet 151 are both located between the two water guide ribs 117, so that the depth of the mounting groove 152 is increased by the water guide ribs 117, and the amount of sewage splashing out is reduced.

[0083] Specifically in some embodiments, a rotating shaft 155 is protruded on two opposite inner walls of the mounting groove 152, and two mounting holes 136 are provided on the switch member 130. The two rotating shafts 155 are respectively penetrated through the two mounting holes 136, so that the switch member 130 can rotate in the mounting groove 152. When the switch member 130 rotates to the first position, the switch member 130 is completely located in the mounting groove 152, so that the mounting member does not protrude from the surface of the cleaning body 110, which is conducive to the cleaning of the cleaning body 110. Further, the above-mentioned limiting hole 112, the opening limiting rib 153 and the closing limiting rib 154 are also arranged in the limiting groove to cooperate with the switch member 130 in the limiting groove to perform the operation of opening and closing the sewage discharge hole 111.

[0084] In some embodiments of the present application, referring to Figure 7, in order to allow the sewage discharged from the bottom of the shell 113 to enter the base station 200, the base station 200 is provided with a sewage trough 220, and when the cleaning body 110 enters the base station 200, the top opening of the sewage trough 220 is located below the sewage hole 111 and the above-mentioned water outlet 151 in the direction of gravity, so that the sewage discharged from the sewage hole 111 passes through the water outlet 151 and finally falls into the sewage trough 220 under the action of gravity for collection.

[0085] Furthermore, in order to centrally process the sewage collected multiple times, the base station 200 also includes a black water tank and a sewage pumping pipe 230. The black water tank is connected to the sewage tank 220 through the sewage pumping pipe 230, and the sewage in the sewage tank 220 can be pumped into the black water tank through the sewage pumping pipe 230. After each cleaning body 110 returns to the base station 200, the sewage will flow into the sewage tank 220 through the sewage hole 111, and finally be pumped into the black water tank for temporary storage so that the user can process it uniformly. Optionally, the base station 200 also includes a vacuum pumping part, which is used to vacuum the black water tank so that the sewage in the sewage tank 220 is pumped into the black water tank under the action of air pressure.

[0086] Furthermore, the base station 200 further includes a plurality of filter ribs 240, all of which are protruding from the bottom wall of the sewage tank 220 and are arranged at intervals around the sewage extraction pipe 230 in the circumferential direction, so that the sewage in the sewage tank 220 first passes through the plurality of filter ribs 240 and is then drawn into the black water tank by the sewage extraction pipe 230. When the sewage passes through the plurality of filter ribs 240, the larger impurities in the sewage will be intercepted by the filter ribs 240, thereby preventing the impurities from entering the sewage extraction pipe 230 and clogging the sewage extraction pipe 230.

[0087] In some embodiments of the present application, the cleaning device 100 is a sweeping robot, and the base station 200 also includes a charging device. After the sweeping robot enters the base station 200, the charging structure on the sweeping robot and the charging device on the base station 200 are connected to each other, thereby forming a charging circuit to start charging, and the sweeping robot can also determine that it has been docked on the base station 200 through the connection of the charging circuit, thereby stopping moving. In some other embodiments, the cleaning device 100 can also be a cleaning device 100 with a self-cleaning function such as a floor scrubber.

[0088] The cleaning device 100 has at least the following advantages:

[0089] When the cleaning body 110 enters the base station 200, the push rod 210 can push the switch 130 to move, thereby realizing the automatic opening of the drain hole 111, and the sewage in the cleaning body 110 can enter the base station 200 through the drain hole 111. When the cleaning body 110 leaves the base station 200, the push rod 210 can close the drain hole 111 under the action of external force, so that the cleaning body 110 can continue to be temporarily stored inside the cleaning device 100 after leaving the base station 200, and be discharged into the base station 200 when it returns to the base station 200 next time. In this way, the cleaning body 110 can realize automatic sewage discharge during the process of entering and leaving the base station 200, so that the sewage generated by the cleaning device 100 each time can be centrally processed at the base station 200, thereby reducing the number of times the user cleans the sewage tank and improving the user experience.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
