[0003] Environmental sanitation is a crucial factor affecting quality of life. Therefore, as people's demands for quality of life continue to rise, so too do their requirements for environmental sanitation. This has led to the development of various floor cleaning devices, commonly including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that simultaneously cleans the floor, vacuums up wastewater, and removes the wastewater from the site.

[0004] In existing floor scrubbers, for the convenience of vacuuming and adding water, the wastewater tank is usually placed on the front of the machine and the cleaning solution tank is placed on the rear. However, when such floor scrubbers are used with base stations, the wastewater tank is far from the base station and the sewage pipeline is complicated, which can easily cause poor sewage discharge and thus affect the user experience.

Detailed Implementation

[0025] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] The specific embodiments of this disclosure are described below with reference to the accompanying drawings.

[0030] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0031] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0032] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0033] This disclosure provides a cleaning device and a cleaning system including the cleaning device and a base station. The cleaning device is used to clean work surfaces such as floors and carpets, while the base station is used to interface with the cleaning device to enable functions such as charging the cleaning device, replenishing cleaning fluid, and discharging wastewater.

[0034] Specifically, the cleaning equipment includes at least a main body, a floor brush assembly, a wastewater tank, and a cleaning solution tank. The main body serves as a carrier for mounting various functional components required for the cleaning equipment, and its bottom surface has a docking area for connecting to a base station. The floor brush assembly is connected to one end of the main body and is used to clean the work surface. Both the cleaning solution tank and the wastewater tank are located on the main body. The cleaning solution tank holds the cleaning solution used to clean the work surface; the cleaning solution can be water or a special cleaning solution for floors or carpets. The wastewater tank holds the dirt sucked from the work surface. With the side of the cleaning equipment facing the user designated as the rear and the side furthest from the user designated as the front, the cleaning solution tank is located on the front of the main body, and the wastewater tank is located on the rear.

[0035] Furthermore, the machine body is equipped with a suction pipe, and the bottom of the sewage tank is equipped with a sewage inlet and a sewage outlet that are respectively connected to the inner cavity of the sewage tank. The sewage inlet is connected to the suction pipe on the machine body, and the sewage inlet is located on the front side of the sewage tank relative to the sewage outlet.

[0036] The wastewater tank is equipped with a sealing component, which is used to open or close the drain outlet. When the drain outlet is closed, the wastewater inside the tank is sealed inside by the sealing component and cannot flow out from the drain outlet; when the drain outlet is opened, the wastewater inside the tank will be discharged from the drain outlet.

[0037] The base station is equipped with a triggering mechanism that engages with the sealing assembly. Specifically, when the cleaning equipment is docked with the base station, the triggering mechanism can move to open the sealing assembly, allowing the dirt in the wastewater tank to flow out through the drain outlet, or move to close the sealing assembly, thus closing the drain outlet.

[0038] When cleaning the work surface is required, the user can place the cleaning equipment's floor brush assembly on the work surface. The cleaning equipment will spray cleaning fluid from its tank onto the floor brush assembly's brush or the work surface. The floor brush on the assembly then repeatedly rotates to wipe away dirt from the work surface. Simultaneously, the cleaning equipment will suck the dirt from the work surface into the inner cavity of the wastewater tank for temporary storage. When cleaning is complete or the wastewater tank is full, the user needs to place the cleaning equipment on the base station and dock it with the base station via the docking area. When the cleaning equipment and the base station are docked, the wastewater tank is located on the side of the equipment closer to the base station, while the cleaning fluid tank is located on the side of the base station furthest away.

[0039] Then, the triggering mechanism on the base station can move to open the sealing component, so that the dirt in the sewage tank can flow out through the drain outlet into the base station, and then be temporarily stored in the sewage tank or discharged directly from the base station; after all the dirt in the sewage tank has been discharged, the triggering mechanism on the base station can close the drain outlet again, so that the user can remove the cleaning equipment from the base station and continue cleaning.

[0040] When a user uses the cleaning equipment disclosed herein to clean a work surface, as the working time increases, the cleaning fluid in the cleaning fluid tank will decrease, while the dirt in the wastewater tank will increase. The center of gravity of the entire cleaning equipment will gradually shift backward toward the user's side, making the user's grip on the cleaning equipment more stable and reducing the risk of the cleaning equipment tilting forward.

[0041] When a user places the cleaning equipment on a base station and connects it, the wastewater tank is located at the rear of the device, closer to the base station, while the inlet is positioned at the front of the tank relative to the outlet. Thanks to the weight of the tank itself and the wastewater inside, the user can quickly connect the cleaning equipment to the base station with minimal or no external force. Furthermore, after connection, the outlet of the wastewater tank, located closer to the base station, is directly above the base station's wastewater tank. This allows the outlet to be opened using a trigger mechanism when the cleaning equipment is placed on the base station. The wastewater inside can then flow directly from the outlet into the base station's wastewater outlet using its own weight, eliminating the need for manual draining or a separate wastewater suction device on the base station. This results in cleaner wastewater discharge, saving time and effort and improving the user experience.

[0042] For ease of understanding, please refer to the following: Figures 1 to 24The present disclosure provides a detailed description of the specific structure and working principle of the cleaning system and cleaning equipment, with reference to one embodiment. It should be noted that, for the sake of brevity, the cleaning equipment and base station are introduced together with the description of the specific structure and working principle of the cleaning system, and are not described separately.

[0043] like Figure 1 and Figure 2 As shown, this disclosure provides a cleaning system, which includes a base station 1 and a cleaning device 2.

[0044] The cleaning device 2 is used to clean work surfaces such as floors and carpets. The cleaning device 2 can also be connected to the base station 1 so that the base station 1 can charge the cleaning device 2, replenish the cleaning solution, and discharge wastewater.

[0045] Specifically, such as Figure 2 As shown, the cleaning device 2 includes at least a body 21, a floor brush assembly 22, a cleaning solution tank 23, and a wastewater tank 24. The body 21 serves as a carrier, constructed to house the various functional components required for installing the cleaning device 2. It should be noted that the directional terms "front" and "rear" used in describing the structure of the cleaning device are based on the user; that is, the side of the cleaning device 2 facing the user is referred to as the rear side, and the side furthest from the user is referred to as the front side.

[0046] like Figures 3 to 5 As shown, the floor brush assembly 22 is located at the bottom of the body 21 and is used to clean work surfaces such as floors, carpets, or furniture surfaces. A pivot 223 can be provided between the floor brush assembly 22 and the body 21. The floor brush assembly 22 can rotate relative to the body 21 through the pivot 223, which makes it convenient for the user to drag the cleaning device 2 back and forth to achieve the purpose of cleaning the work surface.

[0047] Specifically, when cleaning the work surface, the floor brush assembly 22 remains in contact with the work surface. The floor brush assembly 22 may 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 work surface, thereby wiping away stains on the work surface. For example... Figure 5 As shown, a suction pipe 2115 is provided inside the part where the body 21 connects to the floor brush assembly, and the bottom end of the suction pipe 2115 is connected to the suction port 224 provided at the floor brush assembly 22.

[0048] like Figure 3 and Figure 4 As shown, a first mounting slot 211 is provided on the rear side of the body 21, and a corresponding second mounting slot 212 is provided on the front side of the body 21. The first mounting slot 211 is used to install the wastewater tank 24, and the second mounting slot 212 is used to install the cleaning fluid tank 23.

[0049] For details, see Figure 3 The bottom of the first mounting groove 211 is provided with a first bearing part 2111, which is used to bear the weight of the sewage tank 24. When the cleaning equipment 2 is placed on the base station 1, the cleaning equipment is directly connected to the base station 1 through the first bearing part 2111.

[0050] In detail, the bottom end face of the body 21 is provided with a docking area, which is used to directly dock with the base station 1. Specifically, in one embodiment of this disclosure, the docking area may include the bottom end face of the first support part 2111. That is, when the cleaning device 2 is placed on the base station 1, the bottom end face of the first support part 2111 directly docks with the base station 1. Correspondingly, the base station 1 may also be provided with a corresponding receiving area that is opposite to the docking area on the cleaning device 2. Depending on the different structures on the docking area, the receiving area of ​​the base station 1 may be provided with a corresponding structure. The bottom end face of the first support part 2111 and the receiving area of ​​the base station 1 are liquid docking parts. The liquid docking parts are liquid exchange parts between the cleaning device 2 and the base station 1. The cleaning device 2 discharges liquid from the cleaning device 2 into the base station 1 through the liquid docking parts, and the base station 1 injects liquid from the base station 1 into the cleaning device 2 through the liquid docking parts. In one embodiment of this disclosure, the discharge of sewage from the wastewater tank 24 of the cleaning device 2 and the replenishment of cleaning liquid from the cleaning liquid tank 23 are both achieved through the liquid docking parts.

[0051] The wastewater tank 24 is located on the rear side of the body 21 and is used to hold dirt sucked from the working surface. The dirt can be wastewater generated during cleaning or various types of garbage sucked from the working surface. The bottom of the wastewater tank 24 is provided with a drain port 242 and a drain inlet 2411. The drain port 242 of the wastewater tank 24 is used to dock with the base station 1, thereby discharging the dirt in the inner cavity 243 of the wastewater tank 24 into the base station 1.

[0052] like Figure 10 As shown, a sewage discharge trough assembly 11 is provided in the inner cavity of the base station 1. A sewage outlet 111 is provided on the sewage discharge trough assembly 11. The sewage outlet 111 is located on the receiving area of ​​the base station 1 and is used to connect with the sewage outlet 242 of the sewage tank 24, so as to receive the dirt from the sewage outlet 242 of the sewage tank 24.

[0053] Combination Figure 6 and Figure 8The first supporting part 2111 is provided with a through notch 2112, and the sewage outlet 242 is constructed to pass through the notch 2112 and protrude from the bottom of the notch 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 dirt in the sewage tank 24 from splashing. The sewage outlet 242 protruding from the bottom of the notch 2112 means that the sewage outlet 242 extends into the notch 2112, and the sewage outlet 242 is almost flush with the bottom of the notch 2112, but the sewage outlet 242 does not extend beyond the bottom of the notch 2112.

[0054] In one embodiment of this disclosure, the notch 2112 not only penetrates vertically through the first support portion 2111, but also penetrates the side of the first support portion 2111 away from the suction pipe 2115, dividing the first support portion 2111 into two parts located on both sides of the notch 2112. These two parts only connect at the suction pipe 2115. When the sewage tank 24 is installed in the first mounting groove 211, the discharge port 242 is located within the notch 2112, and the outer wall surface of the sewage tank is flush with the outer sides of the two parts of the first support portion 2111 divided by the notch 2112, forming part of the rear contour of the body. The notch 2112 is designed in this way to facilitate the installation and removal of the sewage tank 24, and is not obstructed when installing or removing the sewage tank 24.

[0055] like Figure 3 , Figure 6 and Figure 7 As shown, a positioning port 2114 is also provided at the bottom of the first bearing part 2111. The positioning port 2114 is used to dock with the positioning post 13 provided on the base station 1.

[0056] When a user wants to connect base station 1 and cleaning equipment 2, they can first align and pre-position the positioning port 2114 and the positioning post 13, then allow the cleaning equipment 2 to sit down under its own weight, inserting the positioning post 13 into the positioning port 2114. This allows base station 1 and cleaning equipment 2 to connect quickly and accurately. Furthermore, the cooperation between the positioning post 13 and the positioning port 2114 can limit the movement of the cleaning equipment 2, preventing it from shifting under external force after sitting on base station 1, thus ensuring the stability of the connection.

[0057] See also Figure 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] With this configuration, when the cleaning device 2 is connected to the base station 1, the drain port 242, water inlet 2113 and positioning port 2114 on the cleaning device 2 are respectively connected to the sewage outlet 111, water inlet 12 and positioning column 13 on the base station 1, so that the cleaning device 2 can be fixed on the base station 1, and the dirt in the sewage tank 24 can be discharged into the base station 1, or the base station 1 can replenish the cleaning liquid tank 23 on the cleaning device 2.

[0063] like Figure 9 and Figure 11 As shown, the sewage tank 24 includes a front sidewall 2441 adjacent to the body 21, and an enclosure wall 2442 that surrounds the front sidewall 2441. The front sidewall 2441 and the enclosure wall 2442 together form an inner cavity 243 for storing dirt. The inner cavity 243 is connected to the sewage inlet 2411 and the sewage outlet 242, respectively.

[0064] The sewage inlet 2411 is located near the front side wall 2441, which leaves room for the sewage outlet 242 on the rear side and also increases the size of the inner cavity 243, so that the sewage tank 24 can hold more dirt.

[0065] like Figure 6 and Figure 9 As shown, the sewage outlet 242 of the sewage tank 24 is located behind the sewage inlet 2411 and protrudes downwards from the body 21. With this configuration, when the cleaning device 2 is connected to the base station 1, the sewage outlet 242 first connects with the sewage outlet 111 of the base station 1. As the cleaning device 2 falls towards the base station 1, the sewage outlet 242 can extend into the sewage outlet 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 outlet 111, the lower the probability of dirt splashing to the outside when discharged from the sewage outlet 242.

[0066] Furthermore, since the drain outlet 242 is located behind the sewage tank 24 relative to the sewage inlet 2411, when the cleaning equipment is connected to the base station 1, the drain outlet 242 directly connects and communicates with the sewage outlet 111 of the base station 1. The dirt in the sewage tank 24 flows into the sewage outlet 111 of the base station 1 under its own weight. There is no need to add water pipes or other connecting pipes between the drain outlet 242 and the sewage outlet 111, which simplifies the overall structure of the cleaning system and prevents the accumulation of debris due to bends in the connecting pipes, thus ensuring smooth sewage discharge.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] Specifically, such as Figure 9As shown, in one embodiment of this disclosure, a portion of the front sidewall 2441 of the sewage tank 24 is configured to participate in forming the sewage inlet pipe 241. This effectively saves material used in the sewage tank 24.

[0072] If a separate sewage inlet pipe is configured for the cleaning device 2, dirt will accumulate in the gap between the sewage inlet pipe and the inner wall of the sewage tank 24 after a period of use. This will not only be inconvenient to clean but also produce an odor. The sewage tank disclosed herein utilizes its own structure to form the sewage inlet pipe 241, which effectively solves the above problems and improves the user experience.

[0073] Furthermore, such as Figure 12 As shown, the included angle R between the sewage inlet pipe 241 and the front side wall 2441 is not less than 90°.

[0074] This design ensures that the space between the sewage inlet pipe 241 and the front side wall 2441 is large enough to prevent debris from accumulating. Even if debris does accumulate, users can clean it with tools such as a brush, reducing the likelihood of debris buildup in the sewage tank 24. If the angle between the sewage inlet pipe 241 and the front side wall 2441 is an acute angle less than 90°, a cleaning dead zone can easily form in that acute angle space, resulting in dirt residue.

[0075] In this embodiment, compared with the prior art, the upper end of the suction pipe 2115 is close to the body 21. On the horizontal projection plane, the pipe opening of the suction pipe 2115 is behind the suction port 224. The suction pipe 2115 is inclined upward from the suction port 224 to the pipe opening, without any bends or turns. The sewage inlet pipe 241 of the sewage tank 24 is located at the front side wall 2441 that cooperates with the body 21. The pipe opening of the suction pipe 2115 connects with the sewage inlet 2411 of the sewage inlet pipe 241 along the overall inclined upward trend of the suction pipe 2115. The overall orientation of the suction pipe 2115 is conducive to the formation of negative pressure.

[0076] like Figure 5 , Figure 13 and Figure 14 As shown, the cleaning device 2 also includes a motor assembly 25, which is located on the front side of the body 21 and above the cleaning liquid tank 23. The air intake channel 251 of the motor assembly 25 is configured to communicate with the wastewater tank 24 located on the rear side of the body 21. When the motor assembly 25 is started, a negative pressure will be formed in the wastewater tank 24. Under the action of the negative pressure, the dirt on the working surface is sucked into the inner cavity 243 of the wastewater tank 24 through the suction pipe 2115.

[0077] More in detail, such as Figure 3 and Figure 4As shown, the fuselage 21 includes a first housing 214 located at the rear of the fuselage 21 and a second housing 215 located at the front of the fuselage 21; wherein, the first housing 214 forms a first chamber 2141 at the rear of the fuselage 21 (see Figure 14 The first chamber 2141 is located above the first mounting groove 211, that is, above the wastewater tank 24. The second housing 215 forms a second chamber 2151 on the front side of the body 21, which is located above the second mounting groove 212, that is, above the cleaning fluid tank 23. The motor assembly 25 is located in the second chamber 2151 on the body 21, that is, the motor assembly 25 is located above the cleaning fluid tank 23, and the motor assembly 25 is staggered from the wastewater tank 24.

[0078] like Figure 5 As shown, the air intake channel 251 of the motor assembly 25 extends obliquely from the second chamber 2151 into the first chamber 2141, and then connects with the sewage tank 24. In this way, the air intake channel 251 is not bent, and the motor assembly 25 can form a strong negative pressure in the sewage tank 24, thereby improving the efficiency of the cleaning equipment 2 in sucking up dirt.

[0079] Specifically, such as Figure 5 and Figure 15 As shown, the rear side of the fuselage 21 is provided with a first mating surface 213 for engaging with the upper surface of the sewage tank 24; a negative pressure port 2131 for communicating with the sewage tank 24 is provided on the first mating surface 213; and the air intake channel 251 extends obliquely from the front side of the fuselage 21 to the rear side of the fuselage 21, thereby engaging and communicating with the negative pressure port 2131 on the first mating surface 213.

[0080] like Figure 15 As shown, in this embodiment, the negative pressure port 2131 is composed of multiple holes. 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 multiple holes, it can also have a filtering function, blocking impurities mixed in the air inside the sewage tank 24 and preventing them from entering the motor assembly 25 and affecting the normal operation of the motor.

[0081] like Figure 5 As shown, the intake channel 251 extends obliquely from the center of the bottom of the motor assembly 25, and the exhaust channel 252 extends vertically downward from the edge of the motor assembly 25, offset from the center. The intake channel 251 passes through the exhaust channel 252 and then connects with the negative pressure port 2131 on the first mating surface 213. "The intake channel 251 passes through the exhaust channel 252" means that the intake channel 251 is configured to pass through the exhaust channel 252; the intake channel 251 and the exhaust channel 252 are not connected. This ensures that the air intake of the motor assembly 25 is relatively unobstructed without affecting the normal exhaust of the motor assembly 25.

[0082] like Figure 5 As shown, due to the large size of the motor assembly 25, in the extending direction of the body 21, the orthographic projections of the motor assembly 25 and the cleaning liquid tank 23 on the horizontal plane (approximately perpendicular to the extending direction of the body) at least partially overlap; the orthographic projections of the wastewater tank 24 and the motor assembly 25 on the horizontal plane partially overlap; 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 body 21 can be less than the sum of the thicknesses of the motor assembly 25 and the wastewater tank 24, thereby reducing the space occupied by the body 21 and making the cleaning equipment 2 lighter overall.

[0083] Adaptably, in this embodiment, the size of the second chamber 2151 for accommodating the motor assembly 25 is also larger than the size of the first chamber 2141, and the second chamber 2151 extends toward the rear side of the fuselage 21 and at least partially overlaps with the orthographic projection of the first mating surface 213 on the horizontal plane. This facilitates the connection and communication between the air intake channel 251 of the motor assembly 25 and the negative pressure port 2131 on the first mating surface 213.

[0084] like Figure 5 and Figure 13 As shown, an exhaust port 2132 is also provided on the side wall of the first mating surface 213 adjacent to the sewage tank 24 for mating with the body 21. The exhaust port 2132 is located directly below the exhaust channel 252. The exhaust channel 252 of the motor assembly 25 extends vertically downward from the edge of the motor assembly 25 along the axial direction of the motor assembly 25 to mate with the exhaust port 2132 provided on the first mating surface 213. In this way, the airflow discharged by the motor assembly 25 can be discharged along the exhaust channel 252 of the motor assembly 25 from the exhaust port 2132 on the first mating surface 213, and then discharged to the outside through the gap between the body 21 and the sewage tank 24, thereby maximizing the compactness of the structure.

[0085] like Figure 14 and Figure 15 As shown, in this embodiment, the cleaning device 2 also includes a circuit board assembly 26, which may include the main control board and charging processing circuit board of the cleaning device 2. The circuit board assembly 26 is vertically installed in the first chamber 2141. By separating the accommodating space of the circuit board assembly 26 from that of the motor assembly 25 and placing it in the first chamber 2141 above the sewage tank, the space layout of the cleaning device is fully utilized. Moreover, the vertical arrangement of the circuit board assembly 26 can effectively save the lateral space of the body 21, thereby reducing the required size of the first chamber 2141. This ensures that the size of the second chamber 2151 is larger than that of the first chamber 2141, thus allowing the second chamber 2151 to accommodate the larger motor assembly 25. Figure 11 , Figure 16 and Figure 17As shown, in one embodiment of this disclosure, a top cover support 245 is further provided on the top of the sewage tank 24. The top cover support 245 includes a water-blocking cavity 2452 surrounded by a water-blocking shell 2451 and having an opening at the lower end, and an air outlet channel 2453 isolated from the water-blocking cavity 2452. A sewage inlet pipe 241 is also provided inside the sewage tank 24, 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 tank 24; the other end extends to the outer sidewall of the water-blocking cavity 2452 to form an air inlet 24531. In one embodiment of this disclosure, a filter assembly 2454 may also be provided above the air outlet 24532, which is used to filter out garbage and water in the air.

[0086] It is understandable that by setting a water-blocking cavity 2452, the sewage tank 24 will be blocked when the dirt in the sewage inlet pipe 241 flows out from the top, and will not be directly sucked into the air outlet 2453 by the motor assembly 25. In this way, it can effectively prevent dirt from being sucked into the motor assembly 25 through the air outlet 2453, and avoid the motor assembly 25 from failing to work properly due to water ingress.

[0087] like Figure 15 and Figure 18 As shown, in one embodiment of this disclosure, the water-blocking housing 2451 has an open end on one side adjacent to the front sidewall 2441 of the sewage tank 24; the open end of the water-blocking housing 2451 is sealed to the front sidewall 2441 of the sewage tank 24 by a sealing strip 2455, thereby making the sewage inlet channel and the air outlet channel isolated and independent from each other within the range of the upper cover bracket 245.

[0088] With this configuration, the dirt in the sewage inlet pipe 241 is surrounded by a front sidewall 2441 or a water-blocking shell 2451, which can prevent the dirt in the sewage inlet pipe 241 from being sucked into the motor assembly 25 through the gap between the water-blocking shell 2451 and the front sidewall 2441, thereby ensuring that the motor assembly 25 can work normally.

[0089] like Figure 15 , Figure 17 and Figure 18 As shown, in one embodiment of this disclosure, one end of the air outlet channel 2453 adjacent to the air inlet 24531 extends horizontally on the outer wall of the water baffle cavity 2452, forming an air inlet 24531 that is higher than the bottom opening of the water baffle cavity 2452.

[0090] With this design, even if some dirt reaches the air outlet 2453 from bottom to top, it will be blocked by the horizontally extending outer wall of the air outlet 2453, thus preventing it from directly entering the air outlet 2453.

[0091] Furthermore, since the air inlet 24531 is higher than the bottom opening of the water-blocking cavity 2452, the water-blocking housing 2451 effectively blocks the middle of the air inlet 24531 and the upper opening of the sewage inlet channel. Thus, even under the negative pressure generated by the motor assembly 25, dirt cannot move directly from the top opening of the sewage inlet channel to the air outlet channel 2453, effectively preventing dirt from entering the air outlet channel 2453.

[0092] like Figure 11 and Figure 16 As shown, the water-blocking cavity 2452 divides the inner cavity of the sewage tank 24 into a side facing the front sidewall 2441 and a side away from the front sidewall 2441. The air inlet 24531 is located on the side of the water-blocking cavity 2452 facing the front sidewall 2441. The opening direction of the air inlet 24531 is consistent with the opening end direction 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 sidewall 2441 to facilitate gas flow.

[0093] like Figure 1 and Figure 17 As shown, the air inlet 24531 of the air outlet 2453 is located at the front side in the inner cavity 243 of the sewage tank 24, and the air inlet 24531 faces the front side of the sewage tank 24. The opening direction of the air inlet 24531 faces the side wall of the sewage tank 24. In particular, when the sewage tank 24 is tilted towards the cleaning equipment to perform the cleaning task, the upper side wall of the sewage tank 24 (relative to the lower side wall) is specifically, in this embodiment, the opening direction of the air inlet 24531 faces the front side wall 2441 of the sewage tank 24.

[0094] When the user uses the cleaning device 2, the body 21 will tilt towards the side where the user is, so that the air inlet 24531 of the air outlet 2453 can be in a higher position in the inner cavity 243 of the sewage tank 24, and the air inlet 24531 is also in a tilted upward state.

[0095] Because the dirt inside the inner cavity 243 of the sewage tank 24 will form an upper surface in the horizontal direction under the action of gravity, the air inlet 24531 can be kept as far away from the dirt as possible, so as to prevent the dirt from being sucked into the motor assembly 25 because it is close to the air inlet 24531.

[0096] like 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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, eliminating the need for manual sewage discharge by the user, thereby preventing the user from coming into contact with dirt and improving the user experience.

[0103] In one embodiment of this disclosure, the drain 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; on the other hand, the protruding drain outlet 242 facilitates drainage by extending into the notch 2112. The triggering mechanism of the base station 1 acts on the sealing assembly in a direction perpendicular to the sewage tank 24. The sealing assembly is subjected to the force perpendicular to the sewage tank 24 by the triggering mechanism, which rotates to open and close the drain outlet 242.

[0104] In detail, such as Figure 19 As shown, the sealing assembly includes a sealing cap 2481 hinged to the sewage tank 24 and a latch 2482 for locking the sealing cap 2481. Figure 20 As shown, the sealing cover 2481 can be hinged to the bottom of the sewage tank 24, and a first elastic device 24814 is provided between the sealing cover 2481 and the sewage tank 24. When the latch 2482 disengages 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.

[0105] The latch 2482 is controlled by a trigger mechanism to move to disengage from the sealing cover 2481 so that the sealing cover 2481 opens the drain port 242; the latch 2482 is also configured to be able to reset to lock the sealing cover 2481 so that the sealing cover 2481 closes the drain port 242.

[0106] The latch 2482 is hinged to the sewage tank 24 via a second elastic device, and is configured to return to the locking sealing cover 2481 under the force of the second elastic device after the external force is removed. Specifically, in this embodiment, the latch 2482 is disposed on the sewage tank 24 in a translational or rotatable manner, and the second elastic device is disposed between the latch 2482 and the sewage tank 24; the second elastic device can be a spring or other elastic device.

[0107] like Figure 19 and Figure 21As shown, the triggering mechanism includes a trigger push rod 141 and a reset push rod 142. The trigger push rod 141 can move to push the latch 2482 to displace, so that the latch 2482 disengages from the sealing cover 2481. The reset push rod 142 can move to cooperate with the sealing cover 2481 and push the sealing cover 2481 to overcome the force of the first elastic device 24814 and move to close the drain port 242.

[0108] When the sealing cover 2481 needs to be opened, the trigger push rod 141 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 sewage tank 24 can be discharged from the drain port 242 under its own gravity and enter the sewage tank assembly 11 through the sewage outlet 111 on the top surface of the sewage tank assembly 11.

[0109] 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.

[0110] like Figure 19 and Figure 22 As shown, in one embodiment of this disclosure, a barrier 2484 surrounding the drain outlet 242 is also provided at the bottom of the sewage tank 24. The side of the barrier 2484 facing the trigger push rod 141 has an opening for the trigger push rod 141 and the reset push rod 142 to extend into. Moreover, the bottom of the barrier 2484 is lower than the bottom of the drain outlet 242, that is, the barrier 2484 extends beyond the drain outlet 242 at the bottom. In this way, during the sewage discharge process, the barrier 2484 can restrict the flow direction of the dirt and prevent the dirt from splashing in all directions. In addition, the sealing cover 2481 can also be hinged to the side wall of the barrier 2484 by a first elastic device 24814.

[0111] like Figure 19As shown, trigger push rod 141 and reset push rod 142 are guided and fitted within the inner cavity of base station 1, and are arranged in parallel. Base station 1 also has a drive gear 143 rotatably connected within its inner cavity and located between trigger push rod 141 and reset push rod 142. The opposite sides of drive gear 143 mesh with teeth on trigger push rod 141 and reset push rod 142. Both trigger push rod 141 and reset push rod 142 have racks that mesh with drive gear 143. Because trigger push rod 141 and reset push rod 142 are arranged in parallel and on opposite sides of drive gear 143, when drive gear 143 rotates, the directions of movement of trigger push rod 141 and reset push rod 142 are exactly opposite.

[0112] In this way, Figure 19 Taking the direction of rotation as a reference, when the drive gear 143 rotates counterclockwise, it causes the trigger push rod 141 to move outward and the reset push rod 142 to retract; when the drive gear 143 rotates clockwise, it causes the reset push rod 142 to move outward and retract. It can be seen that the base station 1 of this disclosure can achieve the movement of both the trigger push rod 141 and the reset push rod 142 through a single drive gear 143, thus eliminating the need for additional drive gears 143 and two separate drive mechanisms for driving movement.

[0113] like Figure 19 As shown, in order to facilitate the reset push rod 142 to push the sealing cover 2481 to close the drain port 242, in one embodiment of this 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 plane 24812 connected to the inclined surface 24811. During the extension process of the reset push rod 142, it first moves to cooperate with the inclined surface 24811, thereby pushing the sealing cover 2481 to rotate in the direction of closing the drain port 242. Then, when the reset push rod 142 pushes the sealing cover 2481 to a horizontal position, the reset push rod 142 will be interference-fitted with the plane 24812, thereby giving the sealing cover 2481 an upward thrust, ensuring that the latch 2482 can better lock the sealing cover 2481 on the drain port 242 and prevent gaps from forming between the sealing cover 2481 and the drain port 242.

[0114] like 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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 with 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.

[0120] 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.

[0121] 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.

[0122] Furthermore, when the cleaning device 2 is connected to the base station 1, since the sewage tank 24 is located on the rear side of the body 21, that is, the side close to the base station 1, it is convenient for the docking area on the bottom end face of the body 21 to dock with the base station 1. This allows the dirt in the sewage tank 24 to directly enter the sewage outlet 111 of the base station 1 from the sewage outlet 242 of the sewage tank 24 by its own gravity. There is no need to set up a separate dirt suction device on the base station 1, which can also make the dirt discharge cleaner.

[0123] Application Scenario 1 Since 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 water 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 to 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 to the side where the user is located, 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.

[0124] Application Scenario 2 Since the drain outlet 242 is located behind the sewage tank 24 relative to the sewage inlet 2411, when the cleaning equipment is connected to the base station 1, the drain outlet 242 directly connects and communicates with the sewage outlet 111 of the base station 1. The dirt in the sewage tank 24 flows into the sewage outlet 111 of the base station 1 under its own weight. There is no need to add water pipes or other connecting pipes between the drain outlet 242 and the sewage outlet 111, which simplifies the overall structure of the cleaning system and prevents the accumulation of debris due to bends in the connecting pipes, thus ensuring smooth sewage discharge.

[0125] Application Scenario 3 During the process of cleaning equipment 2 being placed on base station 1 for sewage discharge, since the sewage inlet 2411 is located in front of the sewage tank 24 relative to the sewage outlet 242, when cleaning equipment 2 is placed on base station 1, the sewage outlet 242 will be located on the side closer to base station 1 relative to the sewage inlet 2411. This facilitates the connection between the sewage outlet 242 on sewage tank 24 and base station 1. The dirt in sewage tank 24 can directly enter the sewage outlet 111 of base station 1 by its own gravity, eliminating the need to set up a separate dirt suction device on base station 1, and making the dirt discharge cleaner.

[0126] Application Scenario 4 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.

[0127] 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.

[0128] 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.
