The switch component has a force-bearing portion. When the outside world applies a force to the force-bearing portion, the switch component opens the clean water inlet, so that the clean water pipe from the outside can inject clean water into the sewage tank through the clean water inlet, so as to clean the sewage tank and the solid waste in the sewage tank, and then discharge it through the sewage outlet, thereby avoiding the residual sewage and solid waste in the sewage tank from generating odor, thereby improving the user experience.

[0009] In some embodiments, the switch element is movably disposed on the box body.

[0010] Such an arrangement can avoid the problem of the switch component falling off when opening the clean water inlet.

[0011] In some embodiments, the switch element is slidably connected to the box.

[0025] Such arrangement has a simple structure, is easy to implement and has low cost.

[0026] In some embodiments, the switch member includes a switch body, the force-bearing portion is connected to the switch body, and an inclined angle is formed between the force-bearing portion and the switch body, and the switch body is slidably disposed in the sliding groove.

[0027] Such arrangement enables the switch member to move by applying a relatively small force to the force-bearing part from the outside, so as to open the clean water inlet, thus saving time and effort.

[0028] In some embodiments, the switch assembly further includes a sealing member disposed at the clean water inlet, and the sealing member is configured to seal a gap between the clean water inlet and the clean water pipe.

[0029] Such arrangement can avoid water leakage between the clean water inlet and the clean water pipe, thereby improving the sealing reliability between the clean water inlet and the clean water pipe.

[0030] In some embodiments, the sealing member is a sealing plug having a through hole for a clean water pipe to pass through, and the sealing plug has an avoidance groove on a side facing the switch member, and the avoidance groove is configured to avoid the switch member.

[0069] With the development of science and technology and the improvement of living standards, household cleaning equipment has become more and more popular, reducing the burden of human housework. For example, sweeping robots, floor washing robots, sweeping and mopping robots. In the related art, taking a floor washing machine as an example, in the related art, the floor washing machine includes a main unit and a floor brush assembly, the main unit has a negative pressure device and a sewage tank, the floor brush assembly is used to wet mop the surface to be cleaned (such as the ground), and the negative pressure device is used to provide adsorption wind force to suck the sewage generated by the floor brush assembly during the cleaning process into the sewage tank, wherein the sewage tank is detachably connected to the main unit so that the user can manually clean the sewage in the sewage tank. However, in the related art, when the sewage remains in the sewage tank or the solid garbage in the sewage tank is not cleaned in time, there is a problem of easy generation of odor.

[0070] In order to solve the above problems, the embodiments of the present application provide a sewage tank, a cleaning device and a cleaning system. The sewage tank is provided with a clean water inlet and a sewage outlet on the box body, and an openable and closable switch component is provided at the clean water inlet. The switch component has a force-bearing part. When the outside world applies a force to the force-bearing part, the switch component opens the clean water inlet, so that the clean water pipe from the outside can inject clean water into the sewage tank through the clean water inlet to clean the sewage tank and the solid waste in the sewage tank, and then discharge it through the sewage outlet, thereby avoiding the residual sewage and solid waste in the sewage tank from generating odor, thereby improving the user experience.

[0071] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0072] Please refer to Figures 1 to 11As shown, the embodiment of the present application provides a cleaning system, including a base station 200 and a cleaning device. The base station 200 is suitable for docking the cleaning device; the cleaning device can be a dual-purpose cleaning robot, and illustratively, the cleaning device can be a mopping robot, or a sweeping and mopping robot, or a floor scrubber, etc. The base station 200 can be used to charge the cleaning device, replenish clean water in the clean water tank of the cleaning device, and so on.

[0073] The structures and working principles of the base station 200 and the cleaning device will be described in detail below with reference to the accompanying drawings.

[0074] An embodiment of the present application provides a cleaning device, which includes an equipment body, a clean water tank and a sewage tank 100; wherein the clean water tank can provide cleaning water to the cleaning device when cleaning, for example, the floor, and the cleaning device can collect sewage generated when cleaning the floor into the sewage tank 100.

[0075] Among them, the structure and working principle of the equipment body can be referred to related technologies and will not be repeated here.

[0076] Please refer to Figures 1 to 8 As shown, the sewage tank 100 provided in the embodiment of the present application includes a box body 110, the box body 110 has a accommodating chamber 111 and a sewage inlet 112, and the sewage inlet 112 is connected to the accommodating chamber 111, so that the sewage generated by the cleaning equipment during operation (such as washing or wet mopping) is collected in the accommodating chamber 111 through the sewage inlet 112.

[0077] Exemplarily, the sewage inlet 112 may be disposed at a position close to the top of the box body 110 , so that the capacity of the box body 110 for containing sewage may be increased.

[0078] In some embodiments, the housing 110 further includes a sewage discharge structure 120 , and the sewage discharge structure 120 includes a sewage discharge port 121 communicating with the accommodating chamber 111 , so that sewage in the accommodating chamber 111 can be discharged through the sewage discharge port 121 .

[0079] Exemplarily, the sewage discharge structure 120 has a sewage discharge channel, one end of which is in communication with the accommodating chamber 111 , and the other end of which has a sewage discharge port 121 .

[0080] In order to avoid residual sewage in the box 110 when it is discharged through the sewage outlet 121, in an embodiment of the present application, the sewage discharge channel can be connected with the bottom wall of the box 110 or the side wall close to the bottom wall, so that the sewage in the box 110 can be completely discharged through the sewage discharge channel, avoiding residual sewage in the box 110.

[0081] Also, please refer to Figures 1 to 3As shown, a drain cover 140 is openably and closably provided at the drain outlet 121 , and the drain cover 140 can open or close the drain outlet 121 ; wherein, the drain cover 140 can be separated from the drain outlet 121 under the force applied from the outside.

[0082] Exemplarily, the drain cover 140 is threadedly connected to the drain outlet 121. For example, the drain cover 140 has an internal thread, and the outer side of the drain structure 120 facing the drain outlet 121 has an external thread that matches the internal thread. In this way, the drain cover 140 can be screwed onto the drain outlet 121 by threaded engagement. When the drain cover 140 is subjected to external force, it can be detached from the drain outlet 121 to open the drain outlet 121 to achieve the purpose of draining sewage in the sewage tank 100.

[0083] In order to realize the purpose of automatically opening the drain cover 140 and automatically draining sewage, in some embodiments, an automatic disassembly and assembly mechanism can be provided on the base station 200 suitable for docking the cleaning equipment. When the cleaning equipment is docked at the base station 200, the automatic disassembly and assembly mechanism can apply a force to the drain cover 140 to make the drain cover 140 detach from the drain outlet 121 to open the drain outlet 121, so that the sewage in the sewage tank 100 can be discharged through the drain outlet 121. There is no need to manually clean the sewage tank 100, thereby reducing the burden of manually cleaning the sewage tank 100, thereby improving the user experience.

[0084] In some embodiments, please refer to Figure 3 As shown, the sewage tank 100 also includes a solid-liquid separation structure 160, which is arranged in the accommodating chamber 111 and located between the sewage outlet and the sewage outlet 121. In this way, the sewage entering the accommodating chamber 111 through the sewage outlet can be separated by the solid-liquid separation structure 160 to separate the solid waste in the sewage from the sewage, thereby preventing the solid waste from clogging the sewage channel or the sewage outlet 121.

[0085] It can be understood that the solid-liquid separation structure 160 is provided with a plurality of separation holes arranged at intervals so as to separate solid waste and sewage.

[0086] After the sewage in the sewage tank 100 is discharged through the sewage outlet 121, sewage stains or garbage attached to the tank wall may still remain on the tank wall, or sewage may remain at the bottom of the sewage tank 100, or the solid garbage separated by the solid-liquid separation structure 160 may be cleaned up in time, which may cause the problem of stink and odor over time.

[0087] In view of the above problems, in the embodiments of this application, please refer to Figure 1As shown, a clean water inlet 114 is provided on the box body 110 of the sewage tank 100, and the clean water inlet 114 is constructed as a clean water pipe 220 connecting the accommodating cavity 111 and the outside, so that clean water is injected into the sewage tank 100 through the clean water inlet 114 to clean the sewage tank 100 and the solid waste in the sewage tank 100. The cleaned sewage can be automatically discharged through the sewage outlet 121 to avoid the problem of odor in the sewage tank 100.

[0088] In some embodiments, the clean water inlet 114 is disposed above the solid-liquid separation structure 160. Thus, when clean water is injected into the accommodating chamber 111 through the clean water inlet 114, the solid waste separated on the solid-liquid separation structure 160 can be flushed to avoid the problem of the solid waste becoming smelly and generating odor due to not being cleaned up in time. The residual sewage in the sewage tank 100 can also be cleaned, and the wall of the sewage tank 100 can be cleaned to avoid the generation of odor in the sewage tank 100.

[0089] In some embodiments, the clean water inlet 114 is disposed on the side wall of the box body 110 and is located between the sewage inlet 112 and the solid-liquid separation structure 160. In this way, the distance between the clean water inlet 114 and the solid-liquid separation structure 160 can be reduced, thereby improving the cleaning efficiency of the sewage tank 100.

[0090] Please continue to refer to Figures 1 to 8 As shown, the sewage tank 100 also includes a switch assembly 130, and the switch assembly 130 includes a switch member 131. The switch member 131 is openably and closably arranged at the clean water inlet 114. In this way, when the sewage tank 100 needs to be cleaned, a force can be applied to the switch member 131 so that the switch member 131 opens the clean water inlet 114 to inject clean water into the sewage tank 100 through the clean water inlet 114; when there is no need to inject clean water into the sewage tank 100, the clean water inlet 114 can be closed by the switch member 131.

[0091] In some embodiments, the switch member 131 has a force-bearing portion 1312 , and the force-bearing portion 1312 is configured to be applied with force from the outside so that the switch member 131 opens the clean water inlet 114 .

[0092] Exemplarily, the switch component 131 is detachably arranged at the clean water inlet 114. For example, the switch component 131 can be arranged at the clean water inlet 114 by means of snap connection, threaded connection, etc., so that the switch component 131 can be detached from the clean water inlet 114 under the force applied from the outside; or, the switch component 131 is movably arranged on the box body 110, so that the switch component 131 opens the clean water inlet 114 under the force applied from the outside, so that the clean water pipe 220 from the outside can inject clean water into the accommodating cavity 111 through the clean water inlet 114 to clean the sewage tank 100.

[0093] In order to realize automatic opening of the clean water inlet 114, in some embodiments, the base station 200 suitable for docking the cleaning equipment includes a force-applying mechanism 230. When the sewage tank 100 needs to be cleaned, the force-applying mechanism 230 in the base station 200 applies a force to the switch member 131 to make the switch member 131 open the clean water inlet 114, and make the clean water pipe 220 in the base station 200 connected with the clean water inlet 114 to inject clean water into the accommodating cavity 111, so as to clean the sewage tank 100 and the solid waste in the sewage tank 100 to avoid stink and produce odor, and the sewage tank 100 is manually cleaned with sewage, thereby improving the user's experience.

[0094] In some embodiments, the switch member 131 is movably disposed on the housing 110; illustratively, the switch member 131 is pivotally connected to the housing 110; or, the switch member 131 is slidably disposed on the housing 110. As long as the switch member 131 can open the clean water inlet 114 under the force applied from the outside, no specific limitation is made here.

[0095] For example, Figures 1 to 3 As shown in , the switch member 131 is slidably connected to the housing 110 , so that the switch member 131 slides relative to the housing 110 under the force applied from the outside to open the clean water inlet 114 .

[0096] Please continue to refer to Figure 1 and Figure 2 As shown, a slide groove 115 is provided on the wall surface of the box body 110 , and the switch member 131 is located in the slide groove 115 and can slide along the slide groove 115 under the force applied from the outside.

[0097] Exemplarily, a slide groove 115 is provided on the outer wall surface of the box body 110; exemplary, a protrusion structure is formed on the outer wall surface of the box body 110, and the slide groove 115 is provided on the protrusion structure. The clean water inlet 114 is located in the slide groove 115 and passes through the wall surface of the box body 110, and is connected with the accommodating cavity 111. The switch member 131 is located in the slide groove 115 and slides along the extension direction of the slide groove 115 so that the switch member 131 opens or closes the clean water inlet 114.

[0098] In some embodiments, Figure 1 As shown, the switch member 131 includes a switch body 1311 and a force-bearing portion 1312, the force-bearing portion 1312 is connected to the switch body 1311, and there is an inclined angle between the force-bearing portion 1312 and the switch body 1311, wherein the switch body 1311 is, for example, a plate-like structure, and the switch body 1311 is slidably arranged in the slide groove 115, so that when the force-bearing portion 1312 is subjected to a force applied from the outside, it drives the switch body 1311 to slide in the slide groove 115 toward a side away from the clean water inlet 114, so that the switch body 1311 opens the clean water inlet 114.

[0099] Please continue to refer to Figure 1 As shown, the switch assembly 130 also includes an elastic return member 132, one end of the elastic return member 132 is connected to the groove wall of the slide groove 115, and the other end of the elastic return member 132 is connected to the switch member 131; when the switch member 131 is not subjected to external force, the elastic return member 132 is configured to drive the switch member 131 to move toward one side of the clean water inlet 114 through its own elastic force, so as to close the clean water inlet 114 through the switch member 131.

[0100] Among them, the elastic return member 132 is, for example, a spring, or an elastic block or elastic pad made of elastic material. When the switch member 131 is under the force applied from the outside, the elastic return member 132 is in a compressed state, wherein the fresh water inlet 114 is arranged in the elastic direction of the elastic return member 132; in this way, when the force applied to the switch member 131 is released, the elastic force of the elastic return member 132 itself drives the switch member 131 to move along the elastic direction, so that the switch member 131 closes the fresh water inlet 114.

[0101] For example, in Figure 1 In the embodiment, the elastic reset member 132 is a spring, one end of the spring abuts against the groove wall of the end of the chute 115 away from the clean water inlet 114, and the other end of the spring is connected to the end of the switch member 131 away from the clean water inlet 114. In this way, when, for example, the force-applying mechanism 230 in the base station 200 applies a force to the force-bearing portion 1312 of the switch member 131, the switch member 131 moves toward the end away from the clean water inlet 114 to open the clean water inlet 114. At this time, the spring is located between the switch member 131 and the groove wall of the chute 115 and is in a compressed state (such as Figure 5 and Figure 6 When the force applying mechanism 230 releases the force applied to the switch member 131, the spring drives the switch member 131 to move along the slide groove 115 in the direction of the elastic force by its own elastic force, so that the switch member 131 moves toward one end of the clean water inlet 114, so as to close the clean water inlet 114 through the switch member 131 (as shown in FIG. Figure 7 and Figure 8 ), at which point the spring is in free extension.

[0102] In order to prevent the elastic return member 132 from falling out of the slide groove 115, in some embodiments, a first limiting portion 116 is provided at a position of the groove wall of the slide groove 115 corresponding to the elastic return member 132, and a second limiting portion 1313 is provided at one end of the switch member 131 facing the elastic return member 132, and the two ends of the elastic return member 132 are respectively connected to the first limiting portion 116 and the second limiting portion 1313, so as to limit the elastic return member 132 in the circumferential direction through the first limiting portion 116 and the second limiting portion 1313 to prevent the elastic return member 132 from falling out of the slide groove 115.

[0103] In some embodiments, the first limiting portion 116 and the second limiting portion 1313 are respectively any one of a limiting protrusion or a limiting groove, so as to simplify the structure of the first limiting portion 116 and the second limiting portion 1313, reduce the difficulty of preparation, and thus reduce the cost.

[0104] For example, in Figure 1 , Figure 6 and Figure 8 In the figure, the first limiting portion 116 is a limiting protrusion, the second limiting portion 1313 is a limiting groove, and the elastic return member 132 is a spring. In this way, one end of the spring is sleeved on the limiting protrusion, and the other end of the spring is located in the limiting groove, so as to limit and fix the spring in the circumferential direction to prevent the spring from falling from the slide groove 115.

[0105] In addition, in order to prevent the switch member 131 from falling from the slide groove 115, in the embodiment of the present application, a first guide portion 117 is provided on the groove wall of the slide groove 115, and a second guide portion 1314 matching the first guide portion 117 is provided on the side wall of the switch member 131. The switch member 131 is located in the slide groove 115 and slides in the slide groove 115 along the first guide portion 117 through the second guide portion 1314. Exemplarily, the first guide portion 117 is, for example, one of a guide groove or a guide protrusion, and the second guide portion 1314 is provided on the side wall of the switch member 131. The guide portion 1314 is, for example, the other of a guide groove or a guide protrusion; in this way, on the one hand, the reliability and smoothness of the sliding of the switch member 131 in the slide groove 115 can be improved, and the switch member 131 can be avoided from getting stuck; on the other hand, by making the second guide portion 1314 on the switch member 131 slide along the first guide portion 117 on the groove wall of the slide groove 115, the switch member 131 can be limited in the depth direction of the slide groove 115 to prevent the switch member 131 from falling from the slide groove 115.

[0106] For example, in Figure 1 In the figure, the first guide portion 117 is a guide groove, and the second guide portion 1314 is a guide protrusion (such as a guide rail). When the switch member 131 is set in the slide groove 115, the guide protrusion is located in the guide groove. In this way, the switch member 131 moves along the guide groove in a direction away from the clean water inlet 114 under the force applied from the outside; or, moves along the guide groove in a direction close to the clean water inlet 114 under the elastic force of the elastic reset member 132.

[0107] In some embodiments, please refer to Figure 1 , Figures 5 to 8 As shown, the switch assembly 130 also includes a seal 150, which is disposed at the clean water inlet 114. The seal 150 is configured to seal the gap between the clean water inlet 114 and the clean water pipe 220, thereby improving the sealing performance at the clean water inlet 114 to prevent water leakage at the clean water inlet 114.

[0108] The sealing member 150 may be made of materials having certain sealing and elastic properties, such as rubber and silicone.

[0109] exist Figure 1 , Figures 5 to 8 In the figure, the sealing member 150 is a sealing plug, which is arranged at the clean water inlet 114. The sealing plug has a through hole 151 for the clean water pipe 220 to pass through, and the sealing plug has an avoidance groove 152 on the side facing the switch member 131. In this way, when the switch member 131 moves in the slide groove 115, the avoidance groove 152 is configured to avoid the switch member 131 to avoid interference between the switch member 131 and the sealing plug during movement, thereby improving the smoothness of the movement of the switch member 131.

[0110] It can be understood that the switch member 131 closes the through hole 151 on the sealing plug under the elastic force of the elastic reset member 132; and when the switch member 131 opens the through hole 151 under the action of external force, the external clean water pipe 220 can be passed through the through hole 151 to inject clean water into the sewage tank 100 to clean the sewage tank 100 and avoid the sewage tank 100 from generating odor.

[0111] Since the sealing plug is made of elastic material, the aperture of the through hole 151 on the sealing plug can be smaller than or equal to the radial dimension of the clean water pipe 220. In this way, when the clean water pipe 220 is inserted into the through hole 151, the sealing plug is wrapped around the outer wall surface of the clean water pipe 220, thereby improving the sealing between the sealing plug and the clean water pipe 220 and avoiding water leakage at the through hole 151.

[0112] In some embodiments, a ventilation structure 113 is further provided on the top of the sewage tank 100. Exemplarily, the ventilation structure 113 includes ventilation holes connecting the accommodating chamber 111 with the outside air, so that the air in the accommodating chamber 111 is connected with the outside air, thereby further avoiding the problem of odor generated in the accommodating chamber 111 due to being sealed.

[0113] The embodiment of the present application further provides a base station 200, which includes but is not limited to the docking of the cleaning equipment provided in the above embodiment.

[0114] Please refer to Figures 9 to 11As shown, the base station 200 provided in the embodiment of the present application includes a base station body 210, a clean water pipe 220 and a force-applying mechanism 230, one end of the clean water pipe 220 is configured to be connected to the clean water inlet 114, and the other end of the clean water pipe 220 is configured to be connected to an external water source; illustratively, the external water source is, for example, a water source for a user's household water; the force-applying mechanism 230 includes a force-applying member 231, which is movably arranged on the base station body 210 and connected to the clean water pipe 220, and the force-applying member 231 is configured to drive the clean water The pipe 220 moves toward or away from the sewage tank 100 in the cleaning equipment; when the force-applying member 231 drives the clean water pipe 220 to move toward the sewage tank 100, the force-applying member 231 is configured to apply a force to the switch member 131 on the sewage tank 100 so that the switch member 131 opens the clean water inlet 114. Thereafter, as the force-applying member 231 further moves toward the sewage tank 100, one end of the clean water pipe 220 that faces the sewage tank 100 passes through the clean water inlet 114, so as to inject clean water into the sewage tank 100.

[0115] It can be seen that in the base station 200 provided in the embodiment of the present application, by setting the clean water pipe 220 and the force-applying mechanism 230 on the base station body 210, one end of the clean water pipe 220 is configured to be connected to the clean water inlet 114 on the sewage tank 100, and the other end of the clean water pipe 220 is configured to be connected to the external water source, and the force-applying mechanism 230 includes a force-applying member 231, which is movably arranged on the base station body 210 and connected to the clean water pipe 220, and the force-applying member 231 is configured to drive the clean water pipe 220 to move closer to or away from the sewage tank 100. In this way, when the force-applying member 231 drives the clean water tank to move toward the sewage tank 100, the force-applying member 231 is constructed to apply a force to the switch member 131 on the clean water inlet 114, so that the switch member 131 opens the clean water inlet 114, and the clean water pipe 220 is penetrated in the clean water inlet 114, so as to inject clean water into the sewage tank 100, clean the sewage tank 100, avoid the problem of odor in the sewage tank 100, and do not need manual cleaning, thereby reducing the burden of manual cleaning, thereby improving the user experience.

[0116] In addition, the clean water injected into the sewage tank 100 for cleaning the sewage tank 100 can be discharged through the sewage outlet 121 on the sewage tank 100 after cleaning the sewage tank 100, without manual dumping, thereby reducing the burden of manually cleaning the sewage in the sewage tank 100 and further improving the user experience.

[0117] In some embodiments, the force-applying mechanism 230 also includes a driving component 232, which is configured to drive the force-applying member 231 to move toward or away from the clean water inlet 114, so that when the cleaning equipment is docked at the base station 200, the driving component 232 can provide driving force to the force-applying member 231, so that the force-applying member 231 drives the clean water pipe 220 to move toward the sewage tank 100. In this way, the force-applying member 231 applies a force to the switch member 131 of the clean water inlet 114, so that the switch member 131 opens, and there is no need to manually drive the force-applying member 231 to move relative to the base station body 210, which saves trouble and effort and improves the degree of automation of the base station 200.

[0118] In some embodiments, the driving component 232 includes a driving motor 2321 and a transmission structure, the transmission structure is connected to the force-applying member 231, and the driving motor 2321 is configured to drive the force-applying member 231 to move toward or away from the clean water inlet 114 through the transmission structure. In this way, the driving motor 2321 can transmit the driving force to the force-applying member 231 through the transmission structure, so that the force-applying member 231 moves relative to the base station body 210 to move toward a direction close to the sewage tank 100. The structure is simple, easy to implement, and low in cost.

[0119] In some embodiments, the transmission structure includes a first transmission member 2322 and a second transmission member 2323. The first transmission member 2322 is connected to the output shaft of the driving motor 2321. The first transmission member 2322 is configured to drive the force member 231 to move toward or away from the sewage tank 100 through the second transmission member 2323.

[0120] It can be understood that in the embodiment of the present application, the rotational motion of the drive motor 2321 is converted into linear motion by the first transmission member 2322 and the second transmission member 2323, so that the force-applying member 231 drives the clean water pipe 220 to move toward or away from the sewage tank 100, wherein the specific structure of the first transmission member 2322 and the second transmission member 2323 is not limited.

[0121] Exemplarily, the first transmission member 2322 is, for example, a gear, and the second transmission member 2323 is, for example, a rack, the rack and the gear are meshed with each other, wherein the gear is connected to the output shaft of the drive motor 2321, the rack is meshed with the gear, and the rack is fixedly connected to the force-applying member 231, for example, the rack and the force-applying member 231 are formed into an integrated structure by threaded connection, welding, bonding or one-piece molding process.

[0122] Another exemplary transmission structure is a screw-nut structure, for example, the first transmission member 2322 is a nut, the second transmission member 2323 is a screw, and the output shaft of the drive motor 2321 is connected to the nut. In this way, when the drive motor 2321 drives the nut to rotate, the screw can drive the force member 231 to move relative to the nut toward or away from the sewage tank 100.

[0123] In addition, in order to improve the concentration of the force provided by the force-applying member 231 to the switch member 131 on the sewage tank 100, in the embodiment of the present application, the force-applying member 231 includes a force-applying portion 2311, and the force-applying portion 2311 can match the force-receiving portion 1312 on the switch member 131. In this way, when the cleaning device is docked at the base station 200 and the driving component 232 drives the force-applying member 231 to move toward the sewage tank 100, the force-applying member 231 applies force to the force-receiving portion 1312 on the switch member 131 through the force-applying portion 2311. A force is provided to make the switch member 131 move, for example, in a direction away from the clean water inlet 114. For example, under the pushing action of the force-applying portion 2311, the switch member 131 slides in a direction away from the clean water inlet 114 to open the clean water inlet 114. The force applied by the force-applying portion 2311 to the switch member 131 is concentratedly applied to the force-bearing portion 1312 on the switch member 131 through the force-applying portion 2311, so that the switch member 131 can be driven to open with a smaller force, thereby achieving the purpose of saving time and effort.

[0124] In some embodiments, Figures 9 to 11 As shown, there is an inclined angle between the force applying portion 2311 and the moving direction of the force applying member 231, wherein the moving direction of the force applying member 231 is represented by the H direction (eg Fig.11 As shown in ), the inclined angle between the force applying portion 2311 and the moving direction of the force applying member 231 is represented by α, for example.

[0125] In the embodiment of the present application, an inclined angle is provided between the force-applying portion 2311 and the moving direction of the force-applying member 231. Accordingly, the force-bearing portion 1312 matches the force-applying portion 2311 and also has an inclined angle with the moving direction of the force-applying member 231. In this way, when the force-applying member 231 moves toward the sewage tank 100, the thrust applied by the force-applying member 231 toward the switch member 131 along its moving direction can be converted into a larger thrust through the force-applying portion 2311 and applied to the force-bearing portion 1312 of the switch member 131, thereby achieving the purpose of opening the clean water inlet 114 with a smaller driving force.

[0126] Exemplarily, the value of the inclination angle α between the force-applying portion 2311 and the moving direction of the force-applying member 231 is 30° to 80°. For example, the value of α is 30° to 45°, 45° to 60°, 60° to 80°, etc. Preferably, the value of α is between 45° and 60°; for example, the value of α is 30°, 40°, 45°50°, 55°, 60°, 70°, 80°, etc.

[0127] It can be understood that when the driving force of the force-applying member 231 in its moving direction remains unchanged, the larger the value of α is, the greater the force applied by the force-applying part 2311 to the force-bearing part 1312 of the switch member 131. Specifically, the value of the inclination angle α between the force-applying part 2311 and the moving direction of the force-applying member 231 can be adaptively set according to actual needs, as long as it can satisfy the force applied to the switch member 131 to open the fresh water inlet 114, and no specific limitation is made here.

[0128] When the force-applying member 231 moves toward the sewage tank 100, the force-applying portion 2311 applies a force to the force-receiving portion 1312, so that the force-applying portion 2311 and the force-receiving portion 1312 move relative to each other, so as to drive the switch member 131 to open the clean water inlet 114. Therefore, in order to improve the smoothness of the relative movement between the force-applying portion 2311 and the force-receiving portion 1312, in the embodiment of the present application, the force-applying portion 2311 is a force-applying inclined surface with an inclined angle with the moving direction of the force-applying member 231; the force-receiving portion 1312 is a force-receiving inclined surface matching the force-applying inclined surface, and the force-applying inclined surface is configured to fit with the force-receiving inclined surface. In this way, when the force-applying member 231 moves toward the sewage tank 100, the force-applying inclined surface on the force-applying member 231 and the force-receiving inclined surface on the switch member 131 fit each other and move relative to each other, so that the switch member 131 opens the clean water inlet 114 through the friction between the force-applying inclined surface and the force-receiving inclined surface.

[0129] It can be understood that the force-applying member 231 can slide relative to the base station body 210 in a direction approaching or moving away from the sewage tank 100. Exemplarily, the force-applying member 231 has one of the slide rails or slide grooves 115, and the base station body 210 has the other of the slide rails or slide grooves 115, so that the force-applying member 231 moves along the extension direction of the slide rails and the slide grooves 115 toward the sewage tank 100 under the driving force of the driving component 232, thereby improving the accuracy of the moving direction of the force-applying member 231, improving the accuracy of the alignment position of the clean water pipe 220 and the clean water inlet 114, and further improving the reliability of the clean water pipe 220 injecting clean water into the sewage tank 100.

[0130] In some embodiments, the force-applying member 231 also includes a connecting portion 2312, which is configured to be connected to the clean water pipe 220, so that when the force-applying member 231 moves toward the sewage tank 100, it drives the clean water pipe 220 to move synchronously, so that after the clean water inlet 114 is opened, the clean water pipe 220 is inserted into the clean water inlet 114.

[0131] In some embodiments, the connection portion 2312 is detachably connected to the clean water pipe 220; illustratively, the connection portion 2312 is connected to the clean water pipe 220 via a threaded connector, or the connection portion 2312 is snap-fitted to the clean water pipe 220, etc., as long as a detachable connection between the connection portion 2312 and the clean water pipe 220 can be achieved, it is convenient for maintenance, care or replacement of the connection portion 2312 and the clean water pipe 220 after disassembly.

[0132] As an example, a first clamping portion is provided on the connecting portion 2312, and a second clamping portion matching the first clamping portion is provided on the clean water pipe 220, and the first clamping portion is clamped with the second clamping portion; for example, the first clamping portion is a claw, and the second clamping portion is a slot, so that the connecting portion 2312 and the clean water pipe 220 can be limited in the extension direction of the clean water pipe 220 to avoid relative movement between the clean water pipe 220 and the connecting portion 2312, thereby improving the reliability of the force-applying member 231 in driving the clean water pipe 220 to move.

[0133] In some embodiments, the base station 200 also includes a water inlet pipe 240, one end of which is connected to the clean water pipe 220, and the other end of the water inlet pipe 240 is connected to an external water source, thereby achieving connectivity between the clean water pipe 220 and the external water source. For example, the other end of the water inlet pipe 240 can be connected to a faucet in a user's home so that the water source in the user's home supplies water to the clean water pipe 220 through the water inlet pipe 240.

[0134] It should be noted that the clean water pipe 220 has a certain movable redundant length to prevent the clean water pipe 220 from falling off from the water inlet pipe 240 when the force applying member 231 drives the clean water pipe 220 to move.

[0135] In order to realize automatic opening and closing of the clean water pipe 220, in the embodiment of the present application, a solenoid valve 250 is provided between the water inlet pipe 240 and the clean water pipe 220, and the solenoid valve 250 is configured to open or close the clean water pipe 220, so that the clean water pipe 220 can be opened as needed to clean the sewage tank 100.

[0136] In some embodiments, the base station 200 also includes a one-way valve. Exemplarily, the one-way valve is arranged between the water inlet pipe 240 and a faucet such as an external water source; in addition, a throttle valve may also be arranged on the water inlet pipe 240; wherein, the one-way valve and the throttle valve can refer to the relevant technology and will not be described in detail here.

[0137] In addition, when the force applying member 231 drives the clean water pipe 220 to move toward the sewage tank 100 under the driving force of the driving assembly 232, in order to improve the smoothness of the clean water pipe 220 passing through the clean water inlet 114, in the embodiment of the present application, Fig.11 As shown, the cross-sectional dimension of one end of the clean water pipe 220 facing the sewage tank 100 is smaller than the caliber dimension of the clean water inlet 114, so that there is a gap between the outer wall surface of the clean water pipe 220 and the clean water inlet 114, thereby improving the smoothness of the clean water pipe 220 passing through the clean water inlet 114.
