DETAILED DESCRIPTION

[0054] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of components and steps set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0055] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses.

[0056] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and apparatus can be considered as part of the description of the present disclosure.

[0057] It should be noted that like reference numerals and letters refer to like items throughout the attached drawings, and once an item is defined in one drawing, it is not necessary to discuss it further in subsequent drawings.

[0058] The specific embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0059] In this document, "upper", "lower", "front", "back", "left", "right", and the like are used to describe relative positions between the relevant parts, and do not limit the absolute positions of the relevant parts.

[0060] In this document, "first", "second", and the like are used only to distinguish between each other, and do not indicate importance and order, and are not a prerequisite for each other.

[0061] In this document, "equal", "same", and the like are not strictly limited in the mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and allowed in manufacturing or use.

[0062] The present disclosure provides a cleaning device for cleaning a work surface such as a floor or carpet, and a cleaning system including the cleaning device and a base station for docking with the cleaning device to charge the cleaning device, replenish cleaning fluid, and drain dirty water.

[0063] Specifically, the cleaning device includes a body, a brush assembly, a dirty water tank, and a cleaning fluid tank. The body serves as a carrier for mounting various functional elements required by the cleaning device, and a bottom end surface of the body is provided with a docking area for docking with the base station. The brush assembly is connected to one end of the body and is used to clean the work surface. The cleaning fluid tank and the dirty water tank are both arranged on the body. The cleaning fluid tank is used to contain cleaning fluid for cleaning the work surface, which can be water or a special cleaning fluid for cleaning the floor or carpet. The dirty water tank is used to contain dirt sucked from the work surface. With the side of the cleaning device facing the user being referred to as the back side and the side away from the user being referred to as the front side, the cleaning fluid tank is arranged on the front side of the body, and the dirty water tank is arranged on the back side of the body.

[0064] Moreover, the machine body is provided with a sewage suction pipe, and the sewage tank is provided with a sewage inlet and a sewage outlet at the bottom and communicated with the inner cavity of the sewage tank respectively, the sewage inlet is connected with the sewage suction pipe on the machine body, and the sewage inlet is located at the front side of the sewage tank relative to the sewage outlet.

[0065] The sewage tank is provided with a sealing assembly for opening or closing the sewage outlet. When the sewage outlet is closed, the dirt in the sewage tank is sealed in the sewage tank by the sealing assembly and cannot flow out of the sewage outlet. When the sewage outlet is opened, the dirt in the sewage tank flows out of the sewage outlet.

[0066] The base station is provided with a trigger mechanism for cooperating with the sealing assembly. Specifically, when the cleaning device is connected with the base station, the trigger mechanism can move to open the sealing assembly to make the dirt in the sewage tank flow out of the sewage outlet, or move to close the sealing assembly to close the sewage outlet.

[0067] When the working surface needs to be cleaned, the user can place the floor brush assembly of the cleaning device on the working surface, the cleaning device sprays the cleaning liquid in the cleaning liquid tank to the floor brush of the floor brush assembly or the working surface, and then the floor brush of the floor brush assembly rotates repeatedly to wipe the dirt on the working surface. At the same time, the cleaning device can suck the dirt on the working surface into the inner cavity of the sewage tank for temporary storage. When the cleaning is completed or the sewage tank is full of dirt, the user needs to place the cleaning device on the base station and connect it with the base station through the docking area. When the cleaning device and the base station are connected with each other, the sewage tank is located on the side of the machine body close to the base station, and the cleaning liquid tank is located on the side of the base station away from the base station.

[0068] Then, the trigger mechanism on the base station can move to open the sealing assembly to make the dirt in the sewage tank flow out of the sewage outlet to the inside of the base station, and then temporarily store in the sewage tank or directly discharge from the base station. After the dirt in the sewage tank is completely discharged, the trigger mechanism on the base station can close the sewage outlet again, so that the user can take the cleaning device away from the base station and continue cleaning.

[0069] When the user uses the cleaning device of the present disclosure to clean the working surface, as the working time increases, the cleaning liquid in the cleaning liquid tank will become less and less, and the dirt in the sewage tank will become more and more, and the center of gravity of the cleaning device will gradually shift to the rear side close to the user, making the user hold the cleaning device more and more stable, reducing the risk of forward inclination of the cleaning device.

[0070] When the user places the cleaning device on the base station for docking, since the sewage tank is located at the rear side of the machine body, i.e. the side close to the base station, and the inlet is located at the front side of the sewage tank relative to the outlet, the user can quickly complete the docking between the cleaning device and the base station by means of the weight of the sewage tank and the sewage in the sewage tank without exerting force or exerting a small external force. Moreover, after the cleaning device is docked with the base station, the sewage outlet of the sewage tank located at the side close to the base station can be directly located above the sewage tank of the base station, so that when the cleaning device is placed on the base station, the sewage outlet can be opened by the triggering mechanism, and the dirt in the sewage tank can directly enter the sewage inlet of the base station by means of the gravity of the dirt, without the need for the user to manually discharge the dirt, without the need for separately providing a device for sucking the dirt on the base station, and the dirt can be discharged more cleanly, saving time and effort, and improving the user experience.

[0071] For the sake of convenience, the specific structure of the cleaning system and the cleaning device of the present disclosure and the working principle thereof will be described in detail below with reference to Figures 1 to 24 an embodiment. It should be noted that, in order to keep the text concise, the specific structure of the cleaning system and the working principle thereof are described together with the cleaning device and the base station in the present disclosure, and the two are not described separately.

[0072] As shown in Figure 1 and Figure 2 , the present disclosure provides a cleaning system, which comprises a base station 1 and a cleaning device 2.

[0073] The cleaning device 2 is used to clean the working surface such as the ground or carpet, and the cleaning device 2 can be docked with the base station 1 so that the base station 1 can charge the cleaning device 2, supplement cleaning liquid, discharge sewage, etc.

[0074] Specifically, as shown in Figure 2 , the cleaning device 2 at least comprises a machine body 21, a brush assembly 22, a cleaning liquid tank 23 and a sewage tank 24. The machine body 21 serves as a carrier and is configured to mount various functional elements required by the cleaning device 2. It should be noted that the terms "front" and "rear" used in the description of the structure of the cleaning device herein are set with the user as the reference, i.e. the side of the cleaning device 2 facing the user is recorded as the rear side of the cleaning device 2, and the side away from the user is recorded as the front side of the cleaning device 2.

[0075] As shown in Figures 3 to 5 , the brush assembly 22 is arranged at the bottom end of the machine body 21 and is used to clean the working surface such as the ground, carpet or furniture surface; a rotating shaft 223 can be arranged between the brush assembly 22 and the machine body 21, and the brush assembly 22 can rotate relative to the machine body 21 through the rotating shaft 223, so as to facilitate the user to drag the cleaning device 2 back and forth to achieve the purpose of cleaning the working surface.

[0076] Specifically, when cleaning the working surface, the floor brush assembly 22 is always attached to the working surface, and the floor brush assembly 22 can include a floor brush housing 222 and a floor brush 221 rotatably connected to the floor brush housing 222. The floor brush 221 can rotate relative to the working surface to wipe stains on the working surface. As shown in Figure 5 The part of the machine body 21 connected with the floor brush assembly is provided with a dirt suction pipe 2115, and the bottom end of the dirt suction pipe 2115 is in communication with a dirt suction port 224 provided at the floor brush assembly 22.

[0077] As shown in Figure 3 and Figure 4 A first mounting groove 211 is provided on the rear side of the machine body 21, and a second mounting groove 212 is correspondingly provided on the front side of the machine body 21. The first mounting groove 211 is used for mounting the sewage tank 24, and the second mounting groove 212 is used for mounting the cleaning liquid tank 23.

[0078] Specifically, referring to Figure 3 , the bottom of the first mounting groove 211 is provided with a first bearing part 2111, which is used for bearing the weight of the sewage tank 24, and when the cleaning device 2 is placed on the base station 1, the cleaning device is directly connected with the base station 1 through the first bearing part 2111.

[0079] In detail, the bottom end surface of the machine body 21 is provided with a docking area, which is used for directly docking with the base station 1. Specifically, in an embodiment of the present disclosure, the docking area can include the bottom end surface of the first bearing part 2111. That is, when the cleaning device 2 is placed on the base station 1, the bottom end surface of the first bearing part 2111 directly docks with the base station 1. Correspondingly, the base station 1 can also be provided with a corresponding bearing area to dock with the docking area on the cleaning device 2, and according to the structure on the docking area, the bearing area on the base station 1 can be provided with a corresponding structure. The bottom end surface of the first bearing part 2111 and the bearing area of the base station 1 are liquid docking parts, which are liquid exchange parts of the cleaning device 2 and the base station 1. The cleaning device 2 discharges the liquid in the cleaning device 2 to the base station 1 through the liquid docking part, and the base station 1 injects the liquid in the base station 1 into the cleaning device 2 through the liquid docking part. In an embodiment of the present disclosure, the sewage discharge of the sewage tank 24 and the liquid supplement of the cleaning liquid tank 23 of the cleaning device 2 are both realized through the liquid docking part.

[0080] The sewage tank 24 is provided on the rear side of the machine body 21 and is used for containing the dirt sucked from the working surface. The dirt can be sewage generated during cleaning or various garbage sucked from the working surface. The bottom of the sewage tank 24 is provided with a sewage discharge port 242 and a sewage inlet port 2411. The sewage discharge port 242 of the sewage tank 24 is used for docking with the base station 1, so as to discharge the dirt in the inner cavity 243 of the sewage tank 24 to the base station 1.

[0081] As shown in Figure 10 , the inner cavity of the base station 1 is provided with a sewage groove assembly 11, and the sewage groove assembly 11 is provided with a sewage outlet 111, which is located on the receiving area of the base station 1 and is used to be connected with the sewage outlet 242 of the sewage bucket 24, so as to receive the dirt from the sewage outlet 242 of the sewage bucket 24.

[0082] In combination with Figure 6 and Figure 8 , the first bearing part 2111 is provided with a through gap 2112, and the sewage outlet 242 is configured to pass through the gap 2112 and expose from the bottom of the gap 2112. In this way, after the cleaning equipment 2 is placed on the base station 1, the sewage outlet 242 can extend into the sewage outlet 111 of the base station 1, thereby preventing the dirt in the sewage bucket 24 from splashing. The above-mentioned sewage outlet 242 exposes from the bottom of the gap 2112, which means that the sewage outlet 242 extends into the gap 2112 and is almost flush with the bottom of the gap 2112, but the sewage outlet 242 does not exceed the bottom of the gap 2112.

[0083] In an embodiment of the present disclosure, the gap 2112 not only penetrates the first bearing part 2111 vertically, but also penetrates the first bearing part 2111 away from the sewage suction pipe 2115, thereby dividing the first bearing part 2111 into two parts located on both sides of the gap 2112, and the two parts are only connected at the sewage suction pipe 2115. When the sewage bucket 24 is installed in the first installation groove 211, the sewage outlet 242 is located in the gap 2112, and the outer wall of the sewage bucket is flush with the outer side of the two parts of the first bearing part 2111 divided by the gap 2112, and forms part of the rear contour of the machine body. The gap 2112 is thus arranged to facilitate the installation and removal of the sewage bucket 24, and the installation or removal of the sewage bucket 24 will not be blocked.

[0084] As shown in Figure 3 , Figure 6 and Figure 7 , the bottom of the first bearing part 2111 is further provided with a positioning port 2114, which is used to be connected with the positioning column 13 arranged on the base station 1.

[0085] When the user wants to connect the base station 1 and the cleaning equipment 2, he can first align the positioning port 2114 and the positioning column 13 for pre-positioning, and then make the cleaning equipment 2 fall by gravity, and insert the positioning column 13 into the positioning port 2114, so that the base station 1 and the cleaning equipment 2 can be quickly and accurately connected. In addition, the cooperation of the positioning column 13 and the positioning port 2114 can limit the cleaning equipment 2, so as to avoid displacement of the cleaning equipment 2 when it is subjected to external force after falling on the base station 1, thereby causing failure of the connection between the two, that is, the stability of the connection between the two is ensured.

[0086] Continuing to refer toFigure 4 The bottom of the second mounting slot 212 is provided with a second support part 2122, which is used to support the weight of the cleaning liquid tank 23. That is to say, the cleaning liquid tank 23 is located on the front side of the body 21, that is, the cleaning liquid tank 23 is located on the side of the body 21 away from the user.

[0087] The cleaning solution container 23 is used to hold cleaning solution for cleaning work surfaces. The cleaning solution can be water, or it can be a special cleaning solution for cleaning floors or carpets containing cleaning agents, etc. Figure 6 As shown, a first opening 231 is provided inside the cleaning liquid tank 23, which allows the cleaning liquid inside the cleaning liquid tank 23 to enter and exit.

[0088] like Figure 4 As shown, a first pipe 2121 is provided on the second support part 2122, and one end of the first pipe 2121 is connected to the first opening 231 of the cleaning liquid tank 23. Figure 6 and Figure 7 As shown, the first pipe 2121 extends from the second support portion 2122 to the first support portion 2111, and forms a water inlet 2113 at the bottom of the first support portion 2111.

[0089] like Figure 8 As shown, a water inlet 12 can be installed on the receiving area of ​​base station 1. When the cleaning liquid tank 23 is low on liquid, the user can place the cleaning device 2 on base station 1 so that the water inlet 2113 of the cleaning device 2 is connected to the water inlet 12 on base station 1. This allows the cleaning liquid stored outside or inside the base station to be pumped into the cleaning liquid tank 23 by the external force provided by the water pump through the water inlet 12 on base station 1, the water inlet 2113 on the first bearing part 2111, and the first pipeline 2121, thereby achieving the purpose of replenishing the cleaning liquid tank 23.

[0090] As mentioned above, the docking area of ​​the cleaning device 2 is provided with a notch 2112, a water inlet 2113, and a positioning port 2114. The positioning port 2114 and the water inlet 2113 are located on opposite sides of the notch 2112, meaning the notch 2112 is in the middle of the docking area, and the water inlet 2113 and / or the positioning port 2114 are located on the outer sides of the notch 2112, i.e., on the left and right sides. Correspondingly, the bearing area of ​​the base station 1 is provided with a sewage outlet 111, a water inlet 12, and a positioning post 13. The positioning post 13 and the water inlet 12 are located on opposite sides of the sewage outlet 111. That is, the sewage outlet 111 is in the middle of the bearing area, and the water inlet 12 and / or the positioning post 13 are on the outer sides of the sewage outlet 111. In this way, the positioning post 13 and the water inlet 12 can support the first bearing part 2111 from both sides, thereby preventing unstable docking when the cleaning device 2 docks with the base station 1.

[0091] In this way, when the cleaning device 2 is docked with the base station 1, the sewage outlet 242, the water inlet 2113 and the positioning port 2114 on the cleaning device 2 are respectively docked with the sewage port 111, the water inlet 12 and the positioning column 13 on the base station 1, so that the cleaning device 2 can be fixed on the base station 1, and then the dirty in the sewage tank 24 can be discharged into the base station 1, or the base station 1 can supplement the cleaning liquid to the cleaning liquid tank 23 on the cleaning device 2.

[0092] As shown in Figure 9 and Figure 11 , the sewage tank 24 includes a front side wall 2441 adjacent to one side of the machine body 21, and a surrounding wall 2442 surrounded by the front side wall 2441, and the front side wall 2441 and the surrounding wall 2442 together form an inner cavity 243 for storing dirty, which is in communication with the sewage inlet 2411 and the sewage outlet 242.

[0093] The sewage inlet 2411 is arranged adjacent to the front side wall 2441, so as to leave a position for the sewage outlet 242 on the rear side, and to increase the size of the inner cavity 243, so that the sewage tank 24 can accommodate more dirty.

[0094] As shown in Figure 6 and Figure 9 , the sewage outlet 242 of the sewage tank 24 is located on the rear side of the sewage inlet 2411 and is exposed downward from the machine body 21. In this way, when the cleaning device 2 and the base station 1 are docked, the sewage outlet 242 is first docked with the sewage port 111 of the base station 1, and as the cleaning device 2 falls towards the base station 1, the sewage outlet 242 can extend into the sewage port 111 until the cleaning device is completely seated on the base station 1. It can be understood that the longer the sewage outlet 242 extends into the sewage port 111, the less the probability of dirty splashing outside when the dirty is discharged from the sewage outlet 242.

[0095] In addition, since the sewage outlet 242 is located on the rear side of the sewage tank 24 relative to the sewage inlet 2411, when the cleaning device and the base station 1 are docked, the sewage outlet 242 is directly docked with the sewage port 111 of the base station 1 and is in communication, and the dirty in the sewage tank 24 flows into the sewage port 111 of the base station 1 under the action of gravity, without the need to add a water pipe or other connecting pipeline between the sewage outlet 242 and the sewage port 111, so that the overall structure of the cleaning system is simple, and the accumulation of sundries due to the existence of a bending portion in the connecting pipeline is avoided, thereby ensuring the smoothness of the sewage discharge.

[0096] Furthermore, the center of the inlet 2411 and the center of the outlet 242 are located on the center line of the bottom surface of the wastewater tank 24. That is, the two sides of the bottom surface of the wastewater tank 24 are symmetrical with respect to the inlet 2411 and the outlet 242. On the one hand, the inlet 2411 being in front facilitates the connection between the inlet 2411 and the suction pipe 2115 to collect dirt into the wastewater tank 24, while the outlet 242 being in the rear facilitates the discharge of dirt from the wastewater tank 24 into the outlet 111 below. On the other hand, the center of the inlet 2411 and the outlet 242 being located on the center line of the bottom surface of the wastewater tank 24 is beneficial to the stability when the cleaning equipment and the base station 1 are docked, and also allows sufficient space to be reserved for the water inlets 2113 and / or positioning ports 2114 on both sides of the outlet 242, thus optimizing the spatial layout of the docking components.

[0097] Furthermore, the centerline between the inlet 2411 and the outlet 242 coincides with the centerline of the bottom of the wastewater tank 24. The centerline between the inlet 2411 and the outlet 242 refers to the perpendicular bisector of the line connecting the inlet 2411 and the outlet 242. When this centerline coincides with the centerline of the bottom of the wastewater tank 24, both the inlet 2411 and the outlet 242 have a larger width, thus ensuring smooth suction and discharge of wastewater from the wastewater tank 24. Figure 5 and Figure 12 As shown, the inlet of the suction pipe 2115 extends upward to the upper end face of the first bearing part 2111; and the inlet 2411 of the sewage tank 24 is connected to the inlet of the suction pipe 2115. In this way, dirt on the working surface can enter the suction pipe 2115 inside the body 21 along the suction port 224 at the floor brush assembly 22, and then enter the inlet 2411 of the sewage tank 24 from the suction pipe 2115, and finally enter the inner cavity 243 of the sewage tank 24.

[0098] like Figure 5 and Figure 9 As shown, a sewage inlet pipe 241 is also provided inside the sewage tank 24. One end of the sewage inlet pipe 241 forms a sewage inlet 2411 at the bottom of the sewage tank 24, and the other end is configured to extend upwards towards the sewage tank 24.

[0099] In other words, in this embodiment, the sewage inlet pipe 241 extends vertically or axially along the machine body, and both its sewage inlet 2411 and sewage outlet 242 are located below the connection point between the sewage inlet pipe 241 and the inner cavity of the sewage tank 24. This arrangement avoids the risk of sewage in the sewage tank 24 flowing back to the working surface through the sewage inlet pipe 241, based on the sewage's own gravity.

[0100] Specifically, such as Figure 9As shown, in one embodiment of the present disclosure, part of the front side wall 2441 of the sewage bucket 24 is configured to participate in enclosing the sewage inlet pipe 241. In this way, the material of the sewage bucket 24 can be effectively saved.

[0101] If the sewage inlet pipe is configured separately from the cleaning device 2, after being used for a period of time, dirt will accumulate in the gap between the sewage inlet pipe and the inner wall of the sewage bucket 24, which is not only inconvenient to clean but also produces an odor. The sewage bucket of the present disclosure utilizes its own structure to form the sewage inlet pipe 241, thereby effectively solving the above problem and improving the user experience.

[0102] Further, as shown in Figure 12 , the included angle R between the sewage inlet pipe 241 and the front side wall 2441 is not less than 90°.

[0103] In this way, the space between the sewage inlet pipe 241 and the front side wall 2441 is large enough to be not conducive to the accumulation of sundries, and even if sundries are accumulated, the user can clean them by using a brush or other tools, which can reduce the probability of the accumulation of sundries in the sewage bucket 24. If the included angle between the sewage inlet pipe 241 and the front side wall 2441 is an acute angle less than 90°, a cleaning dead angle will be easily formed in the space of the acute angle, causing dirt to remain.

[0104] In the present embodiment, compared with the prior art, the upper end of the sewage suction pipe 2115 is adjacent to the machine body 21, and on the horizontal projection plane, the pipe opening of the sewage suction pipe 2115 is behind the sewage suction port 224, and the sewage suction pipe 2115 is inclined upward as a whole from the sewage suction port 224 to the pipe opening without a turning-back or bending part. The sewage inlet pipe 241 of the sewage bucket 24 is arranged at the front side wall 2441 matched with the machine body 21, and the pipe opening of the sewage suction pipe 2115 is docked with the sewage inlet port 2411 of the sewage inlet pipe 241 along the overall upward inclination trend of the sewage suction pipe 2115, which is conducive to the formation of negative pressure.

[0105] As shown in Figure 5 , Figure 13 and Figure 14 , the cleaning device 2 further comprises a motor assembly 25, which is arranged on the front side of the machine body 21 and above the cleaning liquid bucket 23, and the air inlet passage 251 of the motor assembly 25 is configured to communicate with the sewage bucket 24 located on the rear side of the machine body 21. When the motor assembly 25 is started, negative pressure will be formed in the sewage bucket 24, and under the action of the negative pressure, the dirt on the working surface will be sucked into the inner cavity 243 of the sewage bucket 24 through the sewage suction pipe 2115.

[0106] More specifically, as shown in Figure 3 and Figure 4 , the motor assembly 25 comprises a motor 2511, a fan 2512, and a filter 2513.As shown, the machine body 21 comprises a first shell 214 located at the rear side of the machine body 21 and a second shell 215 located at the front side of the machine body 21; wherein the first shell 214 encloses a first cavity 2141 at the rear side of the machine body 21 (see Figure 14 ), and the first cavity 2141 is located above the first mounting groove 211, i.e. above the sewage bucket 24. The second shell 215 encloses a second cavity 2151 at the front side of the machine body 21, and the second cavity 2151 is located above the second mounting groove 212, i.e. above the cleaning liquid bucket 23. The motor assembly 25 is located in the second cavity 2151 on the machine body 21, that is, the motor assembly 25 is located above the cleaning liquid bucket 23, and the motor assembly 25 is arranged in a staggered manner with the sewage bucket 24.

[0107] As shown in Figure 5 , the air inlet channel 251 of the motor assembly 25 extends obliquely from the second cavity 2151 into the first cavity 2141, and then communicates with the sewage bucket 24. In this way, the air inlet channel 251 as a whole does not have a bend, and the motor assembly 25 can form a relatively strong negative pressure in the sewage bucket 24, thereby improving the efficiency of the cleaning device 2 in sucking dirt.

[0108] Specifically, as shown in Figure 5 and Figure 15 , the rear side of the machine body 21 is provided with a first docking surface 213 for cooperating with the upper end surface of the sewage bucket 24; a negative pressure port 2131 for communicating with the sewage bucket 24 is arranged on the first docking surface 213; and the air inlet channel 251 extends obliquely from the front side of the machine body 21 to the rear side of the machine body 21, and then communicates with the negative pressure port 2131 on the first docking surface 213.

[0109] As shown in Figure 15 , in this embodiment, the negative pressure port 2131 is composed of a plurality of holes, and of course the negative pressure port 2131 can also be a complete opening. It can be understood that when the negative pressure port 2131 is composed of a plurality of holes, it can have a filtering function, which can block impurities mixed in the air in the sewage bucket 24, preventing them from entering the motor assembly 25 and affecting the normal operation of the motor.

[0110] As shown in Figure 5 , the air inlet channel 251 extends obliquely from the center of the bottom of the motor assembly 25, and the air outlet channel 252 extends vertically downward from the edge of the motor assembly 25, and the air inlet channel 251 communicates with the negative pressure port 2131 on the first docking surface 213 after passing through the air outlet channel 252. Among them, the air inlet channel 251 passing through the air outlet channel 252 means that the air inlet channel 251 penetrates through the air outlet channel 252, and the air inlet channel 251 and the air outlet channel 252 are not communicated. In this way, it can ensure that the air inlet of the motor assembly 25 is relatively unobstructed, and it will not affect the normal exhaust of the motor assembly 25.

[0111] As shown in Figure 5 , due to the large size of the motor assembly 25, in the extension direction of the machine body 21, the motor assembly 25 and the cleaning liquid tank 23 at least partially overlap in the horizontal plane (a plane approximately perpendicular to the extension direction of the machine body) in the orthographic projection; the sewage tank 24 and the motor assembly 25 partially overlap in the horizontal plane in the orthographic projection; more preferably, the cleaning liquid tank 23 is within the orthographic projection of the motor assembly 25. In this way, the thickness of the entire machine body 21 can be less than the sum of the thicknesses of the motor assembly 25 and the sewage tank 24, thereby reducing the space occupied by the machine body 21 and making the cleaning device 2 as a whole more portable.

[0112] Adaptively, in the present embodiment, the size of the second chamber 2151 for accommodating the motor assembly 25 is also larger than that of the first chamber 2141, and the second chamber 2151 extends to the rear side of the machine body 21 and at least partially overlaps with the first docking surface 213 in the horizontal plane in the orthographic projection, so that the air inlet channel 251 of the motor assembly 25 is facilitated to be connected in communication with the negative pressure port 2131 on the first docking surface 213.

[0113] As shown in Figure 5 and Figure 13 , the first docking surface 213 is also provided with an exhaust port 2132 adjacent to the position of the side wall of the sewage tank 24 for cooperation with the machine body 21, and the exhaust port 2132 is located directly below the exhaust channel 252, and the exhaust channel 252 of the motor assembly 25 vertically extends downward along the axial direction of the motor assembly 25 to dock with the exhaust port 2132 provided on the first docking surface 213. In this way, the airflow discharged by the motor assembly 25 can be discharged from the exhaust port 2132 on the first docking surface 213 along the exhaust channel 252 of the motor assembly 25, and then discharged to the outside from the gap between the machine body 21 and the sewage tank 24, thereby maximizing the compactness of the structure.

[0114] As shown in Figure 14 and Figure 15 , in the present embodiment, the cleaning device 2 further comprises a circuit board assembly 26, which can include the main control board and the charging processing circuit board of the cleaning device 2. The circuit board assembly 26 is vertically installed in the first chamber 2141. The circuit board assembly 26 is separated from the accommodation space of the motor assembly 25 and is arranged in the first chamber 2141 above the sewage tank, fully utilizing the spatial layout of the cleaning device, and the vertical arrangement of the circuit board assembly 26 can effectively save the transverse space of the machine body 21, so that the required size of the first chamber 2141 can be smaller, thereby ensuring that the size of the second chamber 2151 is larger than that of the first chamber 2141, and thereby enabling the second chamber 2151 to accommodate the motor assembly 25 with a larger volume. Figure 11 , Figure 16 and Figure 17As shown, in one embodiment of the present disclosure, the upper cover support 245 is further arranged on the top of the sewage bucket 24, and the upper cover support 245 comprises a water blocking cavity 2452 surrounded by a water blocking shell 2451 and having an open lower end, and an air outlet channel 2453 separated from the water blocking cavity 2452; the sewage bucket 24 is further provided with a sewage inlet pipe 241 extending upwards into the water blocking cavity 2452; one end of the air outlet channel 2453 extends upwards and forms an air outlet 24532 on the top of the sewage bucket 24; the other end extends to the outer sidewall of the water blocking cavity 2452 and forms an air inlet 24531. In one embodiment of the present disclosure, a filter assembly 2454 can be further arranged above the air outlet 24532, and the filter assembly 2454 is used to filter out garbage and water in the air.

[0115] It can be understood that, by arranging the water blocking cavity 2452, when the dirt in the sewage inlet pipe 241 flows out from the upper end, the dirt will be blocked in the water blocking cavity 2452 and will not be directly sucked into the air outlet channel 2453 by the motor assembly 25, so that the dirt can be effectively prevented from being sucked into the motor assembly 25 through the air outlet channel 2453, and the motor assembly 25 can work normally without water entering.

[0116] As shown in Figure 15 and Figure 18 , in one embodiment of the present disclosure, the water blocking shell 2451 is formed with an open end adjacent to one side of the front sidewall 2441 of the sewage bucket 24; the open end of the water blocking shell 2451 is sealed with the front sidewall 2441 of the sewage bucket 24 by a sealing strip 2455, so that the sewage inlet channel and the air outlet channel are isolated and independent within the range of the upper cover support 245.

[0117] In this way, the dirt in the sewage inlet pipe 241 is surrounded by the front sidewall 2441 or the water blocking shell 2451, so that the dirt in the sewage inlet pipe 241 can be prevented from being sucked into the motor assembly 25 from the gap between the water blocking shell 2451 and the front sidewall 2441, thereby ensuring that the motor assembly 25 can work normally.

[0118] As shown in Figure 15 , Figure 17 and Figure 18 , in one embodiment of the present disclosure, one end of the air outlet channel 2453 adjacent to the air inlet 24531 extends along the horizontal direction on the outer wall of the water blocking cavity 2452 and forms the air inlet 24531 higher than the bottom opening of the water blocking cavity 2452.

[0119] In this way, even if part of the dirt reaches the air outlet channel 2453 from below, the dirt will be blocked by the outer wall of the air outlet channel 2453 extending in the horizontal direction, so that the dirt cannot directly enter the air outlet channel 2453.

[0120] In addition, since the air inlet 24531 is higher than the bottom opening of the water blocking cavity 2452, the air inlet 24531 and the upper end opening of the dirt inlet channel are blocked by the water blocking shell 2451. In this way, even under the negative pressure formed by the motor assembly 25, dirt cannot directly move from the top end opening of the dirt inlet channel to the air outlet channel 2453, thereby effectively preventing dirt from entering the air outlet channel 2453.

[0121] As shown in Figure 11 and Figure 16 , the water blocking cavity 2452 divides the inner cavity of the dirt bucket 24 into a side facing the front side wall 2441 and a side facing away from the front side wall 2441. The air inlet 24531 is located on the side of the water blocking cavity 2452 facing the front side wall 2441. The opening of the air inlet 24531 is oriented in the same direction as the opening end of the water blocking shell 2451. The air inlet 24531 is located behind the water blocking shell 2451 in the horizontal direction, so as to maintain a sufficient gap with the front side wall 2441 to facilitate air flow.

[0122] As shown in Figure 1 and Figure 17 , the air inlet 24531 of the air outlet channel 2453 is located at the front side of the inner cavity 243 of the dirt bucket 24, and the air inlet 24531 faces the front side direction of the dirt bucket 24. The opening direction of the air inlet 24531 faces the side wall of the dirt bucket 24, in particular, the side wall located above when the cleaning device is inclined to perform a cleaning task (relative to the other side wall located below). In this embodiment, the opening direction of the air inlet 24531 faces the front side wall 2441 of the dirt bucket 24.

[0123] When the user uses the cleaning device 2, the machine body 21 will be inclined to the side of the user. In this way, the air inlet 24531 of the air outlet channel 2453 can be located at the upper position in the inner cavity 243 of the dirt bucket 24, and the air inlet 24531 is also in an inclined upward extending state.

[0124] Since the dirt in the inner cavity 243 of the dirt bucket 24 will form a horizontal upper surface under the action of gravity, the air inlet 24531 can be as far away from the dirt as possible, avoiding the dirt being sucked into the motor assembly 25 due to the proximity of the air inlet 24531.

[0125] As shown in Figure 16As shown in one embodiment of this disclosure, probes 246 for detecting liquid levels are respectively provided on opposite sides of the upper cover bracket 245, and the water-blocking cavity 2452, the air inlet 24531 of the air outlet duct, and the probes 246 can be sequentially distributed in the radial direction of the sewage tank 24. When the probes 246 are wetted with dirt, they can send a full water signal to the cleaning device 2, so the cleaning device 2 can know that there is a lot of dirt in the sewage tank 24, thereby reminding the user to drain the sewage.

[0126] like Figure 16 and Figure 17 As shown, the upper cover bracket 245 has adhesive coatings 247 on its opposite sides, which extend along the axial direction of the upper cover bracket 245. Thus, when the front side wall 2441 or the enclosing wall 2442 is assembled with the upper cover bracket 245 along the axial direction of the upper cover bracket 245, the adhesive coatings 247 can protect the inner wall of the front side wall 2441 or the enclosing wall 2442, preventing the upper cover bracket 245 from scratching the inner wall of the front side wall 2441 or the enclosing wall 2442.

[0127] In this embodiment, the outermost part of the cover bracket 245 consists of two probes 246, and the rubber coating 247 is located on the outer edge of the two probes 246 to prevent the hard probes 246 from scratching the inner wall of the sewage tank 24 when the cover bracket 245 is installed.

[0128] Furthermore, the sewage tank 24 is equipped with a sealing component, which is used to open or close the drain outlet 242. When the drain outlet 242 is closed, the dirt inside the sewage tank 24 is sealed inside the sewage tank 24 by the sealing component and cannot flow out from the drain outlet 242; while when the drain outlet 242 is opened, the dirt inside the sewage tank 24 will be discharged from the drain outlet 242.

[0129] The base station 1 is equipped with a triggering mechanism for cooperating with the sealing assembly. Specifically, when the cleaning device 2 is connected to the base station 1, the triggering mechanism can move to open the sealing assembly to allow the dirt in the sewage tank 24 to flow out through the drain port 242, or move to close the sealing assembly to close the drain port 242.

[0130] When cleaning is complete or the wastewater tank 24 is full, the user needs to place the cleaning device 2 on the base station 1. Then, the trigger mechanism on the base station 1 can move to open the sealing assembly, allowing the dirt in the wastewater tank 24 to flow out through the drain port 242 into the base station 1, where it can be temporarily stored in the wastewater tank or discharged directly from the base station 1 through the wastewater tank. After all the dirt in the wastewater tank 24 has been discharged, the trigger mechanism on the base station 1 can close the drain port 242 again, allowing the user to remove the cleaning device 2 from the base station 1 and continue cleaning.

[0131] The dirty water in the sewage tank 24 can be sealed by the sealing assembly during the operation of the cleaning device 2, and then the dirty water in the sewage tank 24 can be automatically discharged by the triggering mechanism when the cleaning device 2 is placed on the base station 1, without the need for the user to manually discharge the dirty water, so that the user can avoid contacting the dirty water, thereby improving the user experience.

[0132] In one embodiment of the present disclosure, the sewage outlet 242 and the sealing assembly protrude from the bottom surface of the sewage tank 24. On the one hand, the capacity of the sewage tank 24 is not limited, and on the other hand, the protruding sewage outlet 242 is convenient to extend into the gap 2112 for sewage discharge. The triggering mechanism of the base station 1 acts on the sealing assembly in a direction perpendicular to the sewage tank 24, and the sealing assembly is subjected to the force of the triggering mechanism perpendicular to the sewage tank 24, so as to rotationally open and close the sewage outlet 242.

[0133] In detail, as shown in Figure 19 , the sealing assembly includes a sealing cover 2481 hinged on the sewage tank 24 and a lock catch 2482 for locking the sealing cover 2481. As shown in Figure 20 , the sealing cover 2481 can be pivotally hinged on the bottom of the sewage tank 24, and a first elastic device 24814 is arranged between the sealing cover 2481 and the sewage tank 24, and when the lock catch 2482 is disengaged from the sealing cover 2481, the sealing cover 2481 opens the sewage outlet 242 under the action of the first elastic device 24814. The first elastic device 24814 can be a torsion spring or other elastic device.

[0134] The lock catch 2482 is controlled to move away from the sealing cover 2481 by the triggering mechanism, so that the sealing cover 2481 opens the sewage outlet 242; the lock catch 2482 is also configured to be reset to lock the sealing cover 2481, so that the sealing cover 2481 closes the sewage outlet 242.

[0135] The lock catch 2482 is hinged on the sewage tank 24 by a second elastic device, and is configured to be reset to lock the sealing cover 2481 under the action of the second elastic device after the external force is removed. Specifically, in the present embodiment, the lock catch 2482 is arranged on the sewage tank 24 in a translatable or rotatable manner, and the second elastic device is arranged between the lock catch 2482 and the sewage tank 24; the second elastic device can be a spring or other elastic device.

[0136] As shown in Figure 19 and Figure 21As shown, the trigger mechanism includes a trigger push rod 141 and a reset push rod 142, the trigger push rod 141 is capable of moving to push the lock catch 2482 to displace, so that the lock catch 2482 is disengaged from the sealing cover 2481; the reset push rod 142 is capable of moving to cooperate with the sealing cover 2481 and push the sealing cover 2481 to move to close the drain 242 against the force of the first elastic device 24814.

[0137] When it is needed to open the sealing cover 2481, the trigger push rod 141 is capable of moving to push the lock catch 2482 to displace, so that the lock catch 2482 is disengaged from the sealing cover 2481, and when the lock catch 2482 is disengaged from the sealing cover 2481, the sealing cover 2481 is capable of opening the drain 242 under the action of the torsion spring. In this way, the dirt in the sewage bucket 24 can be discharged from the drain 242 under the action of its own gravity, and enter the drain groove assembly 11 through the sewage outlet 111 on the top surface of the drain groove assembly 11.

[0138] When the dirt in the sewage bucket 24 is completely discharged from the drain 242, the reset push rod 142 is capable of moving to cooperate with the sealing cover 2481 and push the sealing cover 2481 to move to close the drain 242, and then the lock catch 2482 is capable of resetting to lock the sealing cover 2481 on the drain 242 under the action of the second elastic device, so as to close the drain 242.

[0139] As shown in Figure 19 and Figure 22 In one embodiment of the present disclosure, a surrounding fence 2484 surrounding the drain 242 is further arranged at the bottom of the sewage bucket 24, the side of the surrounding fence 2484 facing the trigger push rod 141 is an open end for the trigger push rod 141 and the reset push rod 142 to extend into, and the bottom of the surrounding fence 2484 is lower than the bottom of the drain 242, that is, the surrounding fence 2484 protrudes beyond the drain 242 at the bottom. In this way, during the drainage process, the surrounding fence 2484 is capable of limiting the flow direction of the dirt to prevent the dirt from splashing around. Moreover, the sealing cover 2481 can be hinged to the side wall of the surrounding fence 2484 through the first elastic device 24814.

[0140] As shown in Figure 19As shown, the trigger push rod 141 and the reset push rod 142 are guided and matched in the inner cavity of the base station 1, and the trigger push rod 141 and the reset push rod 142 are arranged in parallel; The base station 1 is also provided with a driving gear 143 rotatably connected in the inner cavity of the base station 1 and located between the trigger push rod 141 and the reset push rod 142, and the opposite sides of the driving gear 143 are respectively engaged with the teeth provided on the trigger push rod 141 and the reset push rod 142. The trigger push rod 141 and the reset push rod 142 are both provided with a gear rack engaged with the driving gear 143. Since the trigger push rod 141 and the reset push rod 142 are arranged in parallel and are arranged on both sides of the driving gear 143, when the driving gear 143 rotates, the movement directions of the trigger push rod 141 and the reset push rod 142 are just opposite.

[0141] In this way, according to the directions in Figure 19 , when the driving gear 143 rotates in the counterclockwise direction, the trigger push rod 141 can be moved outward, and the reset push rod 142 can be retracted; When the driving gear 143 rotates in the clockwise direction, the reset push rod 142 can be moved outward, and the reset push rod 142 can be retracted. It can be seen that the base station 1 of the present disclosure can realize the movement of the trigger push rod 141 and the reset push rod 142 by one driving gear 143, so as to save more driving gears 143 and not need to set two driving mechanisms to drive the movement separately.

[0142] As shown in Figure 19 , in order to facilitate the reset push rod 142 to push the sealing cover 2481 to move to close the blowdown port 242, in an embodiment of the present disclosure, the bottom end face of the sealing cover 2481 has a gradually downward extending inclined surface 24811 from the position adjacent to the reset push rod 142 to the position away from the reset push rod 142, and a flat surface 24812 connected with the inclined surface 24811. During the extension of the reset push rod 142, it will first move to cooperate with the inclined surface 24811, so as to push the sealing cover 2481 to rotate in the direction of closing the blowdown port 242, and then the reset push rod 142 pushes the sealing cover 2481 to the horizontal position of the sealing cover 2481. The reset push rod 142 will be interference fit with the flat surface 24812, so as to give the sealing cover 2481 an upward pushing force, so that the locking buckle 2482 can better lock the sealing cover 2481 on the blowdown port 242, preventing a gap between the sealing cover 2481 and the blowdown port 242.

[0143] As shown in Figure 19As shown, in one embodiment of this disclosure, a sealing gasket 24813 is provided on the sealing cover 2481, and the area of ​​the sealing gasket 24813 is larger than the area of ​​the drain outlet 242; the sealing cover 2481 is sealed to the entire end face of the drain outlet 242 by the sealing gasket 24813. In this way, the sealing gasket 24813 can not only maintain close contact with the drain outlet 242 to ensure that dirt is sealed in the sewage tank 24; but also, during the sewage discharge process, dirt is not easily left on the smooth surface of the sealing gasket 24813.

[0144] like Figure 10 and Figure 19 As shown, in one embodiment of this disclosure, the trigger push rod 141 can move to a position that extends into the drain tank assembly 11 and is higher than the bottom end face of the drain port 242. In this way, the trigger push rod 141 can avoid the position of the sealing cover 2481 and prevent it from affecting the arrangement of the reset push rod 142.

[0145] like Figure 10 and Figure 19 As shown, in one embodiment of this disclosure, the reset push rod 142 is configured to extend into the drain tank assembly 11 through the through hole 112 and be positioned below the bottom end face of the drain port 242. In this way, the reset push rod 142 can be aligned with the position of the sealing cover 2481, thereby pushing the sealing cover 2481 to move to close the drain port 242.

[0146] Furthermore, the sewage discharge trough assembly 11 is provided with a through hole 112 for the reset push rod 142 to pass through. A sealing element 144 is provided at the end of the reset push rod 142. The sealing element 144 can seal the through hole 112 after the reset push rod 142 is reset. In this way, the sealing element 144 can seal the through hole 112 during the sewage discharge process, preventing dirt from splashing into the through hole 112 and avoiding dirt residue in the through hole 112.

[0147] like Figure 19 As shown, in one embodiment of this disclosure, the sealing cover 2481 is hinged to the side wall of the enclosure 2484 or to the bottom of the sewage tank 24 on one side adjacent to the reset push rod 142, and the opposite side is configured to rotate in the direction of the reset push rod 142 to open the drain port 242. In this way, the sealing cover 2481 can also block the location of the through hole 112 during the sewage discharge process, further preventing dirt from splashing into the through hole 112 and avoiding dirt residue in the through hole 112.

[0148] like Figure 19 As shown, since the sealing cover 2481 is hinged to the side wall of the enclosure 2484 or to the bottom of the sewage tank 24 on the side adjacent to the reset push rod 142, the latch 2482 can only be located on the side of the drain outlet 242 away from the trigger push rod 141 and the reset push rod 142. To achieve the purpose of the trigger push rod 141 pushing the latch 2482, as shown... Figure 19, Figure 23 and Figure 24 As shown, in one embodiment of this disclosure, a release rod 2483 is provided on the sewage tank 24 and is guided and engaged on the sewage tank 24. The release rod 2483 extends from the position of the latch 2482 to the side of the sewage outlet 242 adjacent to the trigger push rod 141. The release rod 2483 is provided with an operating area (see...). Figure 22 The action area is flush with the outer wall of the sewage tank 24, allowing the trigger push rod 141 to abut against it. The abutment of the trigger push rod 141 against this action area causes the release linkage 2483 to move. Figure 19 Taking the direction of movement as an example, under the action of the trigger push rod 141, the release link 2483 can move to the left (the release link 2483 moves in the same direction as the trigger push rod 141), pushing the latch 2482 to the left (the latch 2482 moves away from the sealing cover 2481), thereby disengaging the latch 2482 from the sealing cover 2481. After the trigger push rod 141 is removed, the release link 2483 can move to the right under the action of the spring, thereby resetting the latch 2482.

[0149] like Figure 5 As shown, the cleaning device 2 of this disclosure also includes a handle 27, which is mounted on the rear portion of the top of the body 21. This allows the user to hold the handle 27 while cleaning the work surface and repeatedly pull the cleaning device 2 to achieve the purpose of cleaning the work surface. Figure 5 As shown, in one embodiment of this disclosure, the axis of the inlet 2411 is located between the axis of the handle 27 (the axis of the vertical part of the handle) and the axis of the motor assembly 25. Since the handle 27 is mounted on the rear part of the top of the body 21, and the motor assembly 25 is located in the second chamber 2151 located on the front side of the body 21, the inlet 2411 can be located as close as possible to the center of the body 21, so that the suction pipe 2115 is connected as close as possible to the center of the body 21, neither too far forward nor too far back, thereby making the main motor suction more efficient and making it easier for the user to clean the work surface.

[0150] In summary, the cleaning liquid tank 23 of this disclosure is located on the front side of the machine body 21, and the wastewater tank 24 is located on the rear side of the machine body 21. When the user uses the cleaning equipment 2 of this disclosure for cleaning, the cleaning liquid in the cleaning liquid tank 23 will decrease, while the dirt in the wastewater tank 24 will increase. Thus, during the process of the user using the cleaning equipment 2 to clean the work surface, the center of gravity of the machine body 21 will gradually shift towards the side where the wastewater tank 24 is located. That is, during the process of the user using the cleaning equipment 2, the center of gravity of the machine body 21 will gradually shift towards the user's side, thereby making the user hold the cleaning equipment 2 more stably and preventing the machine body 21 of the cleaning equipment 2 from tilting forward.

[0151] Moreover, when the cleaning device 2 is docked with the base station 1, since the sewage tank 24 is located at the rear side of the machine body 21, i.e., close to the base station 1, the docking area on the bottom end surface of the machine body 21 can be docked with the base station 1, so that the dirt in the sewage tank 24 can directly flow into the sewage inlet 111 of the base station 1 by gravity, without the need to separately provide a device for sucking the dirt on the base station 1, and the dirt can be discharged more cleanly.

[0152] Application scenario one

[0153] Since the cleaning liquid tank 23 is arranged on the front side of the machine body 21, and the sewage tank 24 is arranged on the rear side of the machine body 21, when a user uses the cleaning device 2 for cleaning, the cleaning liquid in the water in the cleaning liquid tank 23 will become less and less, and the dirt in the sewage tank 24 will become more and more, so that during the process of the user using the cleaning device 2 to clean the working surface, the center of gravity of the machine body 21 will gradually shift to the side where the sewage tank 24 is located, i.e., the center of gravity of the machine body 21 will gradually shift to the side where the user is located during the process of the user using the cleaning device 2, so that the user can hold the cleaning device 2 more stably, and the machine body 21 of the cleaning device 2 will not be inclined forward.

[0154] Application scenario two

[0155] Since the sewage outlet 242 is located at the rear side of the sewage tank 24 relative to the sewage inlet 2411, when the cleaning device 2 is docked with the base station 1, the sewage outlet 242 is directly docked with and connected to the sewage inlet 111 of the base station 1, and the dirt in the sewage tank 24 flows into the sewage inlet 111 of the base station 1 by gravity, without the need to additionally provide a connecting pipeline such as a water pipe between the sewage outlet 242 and the sewage inlet 111, so that the overall structure of the cleaning system is simple, and dirt will not be accumulated due to a bending part in the connecting pipeline, so that the sewage discharge is smooth.

[0156] Application scenario three

[0157] During the process of the cleaning device 2 being placed on the base station 1 for discharging sewage, since the sewage inlet 2411 is located at the front side of the sewage tank 24 relative to the sewage outlet 242, when the cleaning device 2 is placed on the base station 1, the sewage outlet 242 is located close to the base station 1 relative to the sewage inlet 2411, so that the sewage outlet 242 on the sewage tank 24 can be docked with the base station 1, and the dirt in the sewage tank 24 can directly flow into the sewage inlet 111 of the base station 1 by gravity, without the need to separately provide a device for sucking the dirt on the base station 1, and the dirt can be discharged more cleanly.

[0158] Application scenario four

[0159] When cleaning is complete or the wastewater tank 24 is full, the user needs to place the cleaning device 2 on the base station 1. Then, the trigger push rod 141 on the base station 1 can move to push the latch 2482 to displace, so that the latch 2482 moves and disengages from the sealing cover 2481. After the latch 2482 disengages from the sealing cover 2481, the sealing cover 2481 can open the drain port 242 under the action of the torsion spring. In this way, the dirt in the wastewater tank 24 can be discharged from the drain port 242 under its own gravity, and enter the sewage tank assembly 11 through the wastewater outlet 111 on the base station 1.

[0160] After all the dirt in the sewage tank 24 is discharged from the sewage outlet 242, the reset push rod 142 can move to cooperate with the sealing cover 2481 and push the sealing cover 2481 to close the sewage outlet 242. Then, the latch 2482 can be reset under the action of the second elastic device to lock the sealing cover 2481 on the sewage outlet 242 to close the sewage outlet 242.

[0161] Therefore, in the cleaning device 2 disclosed herein, dirt can be sealed in the sewage tank 24 by a sealing component during the operation of the cleaning device 2. Then, when the cleaning device 2 is placed on the base station 1, the sewage in the sewage tank 24 can be automatically discharged by a triggering mechanism, without the need for the user to manually discharge the sewage, thereby avoiding the user from coming into contact with dirt and improving the user experience.
