Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a sewage tank, cleaning equipment and a cleaning system. Background Art

[0003] The automation and intelligence of cleaning equipment are becoming more and more common. For example, floor scrubbers can significantly reduce the workload of users when cleaning the floor.

[0004] After using the floor scrubber, the sewage in the sewage tank needs to be discharged. In the prior art, the sewage in the sewage tank is discharged by its own gravity; however, this gravity direct discharge method has low discharge efficiency, and the sewage pipe is prone to blockage during the discharge process, which poses a risk of sewage leakage and affects the user experience of the cleaning equipment and cleaning system. Utility Model Content

[0005] The embodiments of the present application provide a sewage tank, a cleaning device and a cleaning system, which are used to solve the technical problems in the above-mentioned related technologies that the direct gravity discharge of sewage has low discharge efficiency and is prone to clogging of sewage pipes during the discharge process.

[0006] In order to achieve the above objectives, the present application provides the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a sewage tank, comprising: a box body, wherein the bottom of the box body is provided with a sewage outlet; a valve bracket, wherein the valve bracket is arranged at the bottom of the box body and has a through opening at a position opposite to the sewage outlet; a valve assembly, wherein the valve assembly comprises a cover plate and a lock, wherein the cover plate is used to seal the sewage outlet or to open the sewage outlet during positive pressure sewage discharge; a side wall of the through opening is provided with a channel on which the lock can be movably arranged, and the lock is used to lock or unlock the cover plate; a first sealing member, wherein the first sealing member is arranged on the lock, and after the lock unlocks the cover plate, the first sealing member seals between the lock and the channel; a second sealing member, wherein the second sealing member is arranged around the outer peripheral side of the sewage outlet, and the second sealing member is used to seal the joint between the sewage outlet and the through opening.

[0008] The embodiment of the present application provides a sewage tank, which can open the valve assembly to discharge sewage by using the cover plate and the lock in the valve assembly; and can seal the sewage outlet to prevent sewage from leaking from the sewage outlet when sewage is not needed. Furthermore, the present application can effectively improve the discharge efficiency of the sewage in the sewage tank by adopting positive pressure sewage discharge, and can easily discharge the stains or residues in the box under the action of positive pressure, so as to keep the inside of the box clean and avoid solid garbage blocking the sewage pipe during the sewage discharge process.

[0009] Furthermore, by arranging a first seal at the lock, it can be achieved that during positive pressure sewage discharge, after the lock unlocks the cover plate, the lock and the channel are sealed, thereby preventing sewage from leaking from the joint between the port on the valve bracket and the channel during positive pressure sewage discharge in the sewage tank, for example, sewage from leaking from the gap between the port and the channel, thereby improving the user experience of the cleaning equipment and the cleaning system.

[0010] In addition, since the probability of sewage leaking between the lock buckle and the channel is reduced, the efficiency of sewage being discharged from the cleaning equipment through the sewage outlet and the through port can be improved.

[0011] Furthermore, by arranging a second sealing member on the outer peripheral side of the sewage outlet, the end of the through port facing the sewage outlet can be indirectly connected with the docking point of the sewage outlet through the second sealing member, so that the docking point between the through port and the sewage outlet can be sealed by the second sealing member, which can reduce the probability of sewage leakage from the docking point between the through port and the sewage outlet, improve the sealing effect at the sewage outlet, reduce the risk of sewage leakage, and further improve the user experience of the cleaning equipment and the cleaning system.

[0012] Based on the above technical solution, the present application can also be improved as follows.

[0013] In a possible implementation, the bottom of the box body has a mounting groove, the mounting groove is arranged on the outer peripheral side of the sewage outlet, the second sealing member is arranged in the mounting groove and is sealed and abutted with the end of the opening of the valve bracket toward the bottom of the box body.

[0014] In this way, by arranging a mounting groove at the bottom of the box body, with the groove opening of the mounting groove facing the bottom of the box body, and the second seal being arranged in the mounting groove, the surface of the second seal facing the bottom of the box body can be in contact with the groove bottom of the mounting groove. The side surface of the second seal can also be in contact with the side surface of the mounting groove at the bottom of the box body. Under the mutual abutment between the side wall of the mounting groove and the side wall of the second seal, the probability of the second seal being offset or shaking in the height direction perpendicular to the box body is reduced, thereby improving the installation stability of the second seal, and improving the sealing stability at the through port and the sewage outlet, thereby improving the sealing effect of the sewage tank.

[0015] In a possible implementation, the valve bracket has a moving space, and the first opening and the second opening are formed on two opposite first inner walls of the moving space; the first opening extends to the inner wall of the through port and is connected with the through port, and a connecting channel is formed between the first opening and the second opening; the first sealing member is located in the moving space, and after the lock unlocks the cover plate, the first sealing member seals the second opening.

[0016] In this way, by setting a moving space on the valve bracket and setting the lock buckle and the first seal in the moving space, the lock buckle and the first seal can be protected to prevent the lock buckle and the first seal from being affected by other components, thereby improving the protection of the lock buckle and the first seal, as well as the working stability of the lock buckle and the first seal, thereby improving the working stability of the sewage tank.

[0017] Furthermore, by connecting the first opening with the through port, the lock moves in the channel connected between the first opening and the second opening, and after the lock unlocks the cover plate, the first seal seals the second opening, thereby preventing sewage from entering the moving space and the channel through the connection between the first opening and the through port, and further leaking from the second opening to the outside of the valve bracket, thereby reducing the risk of sewage leakage.

[0018] The moving space also has two second inner walls perpendicular to the first inner wall, the two second inner walls are arranged opposite to each other, and the first sealing member does not contact the second inner walls.

[0019] In this way, by preventing the first seal from contacting the two opposite second inner walls in the moving space, the first seal can be prevented from contacting the second inner walls during the process of the lock driving the first seal to move in the channel, thereby preventing the sliding friction resistance generated by the contact between the first seal and the second inner wall from affecting the movement of the second seal, and preventing the wear caused by the sliding friction between the first seal and the second inner wall, thereby improving the stability of the lock and the first seal during the movement process, reducing the wear of the first seal and increasing the service life of the first seal.

[0020] In a possible implementation, a first opening is formed on a side wall of the through opening, and the first opening forms the passage; the first sealing member is located in the through opening, and after the lock unlocks the cover plate, the first sealing member seals the first opening.

[0021] In this way, by forming a channel through the first opening, the lock can move in the first opening, and the first sealing member is located in the through opening, so that after the lock unlocks the cover plate, the first sealing member seals the first opening from the inside of the through opening to prevent sewage in the through opening from leaking through the first opening, thereby improving the sealing effect.

[0022] In a possible implementation, the first sealing member includes a connecting portion and a sealing portion; the connecting portion is sleeved on the outer peripheral side of the lock buckle, and the sealing portion is arranged on the outer peripheral side of the connecting portion; the sealing portion is used to seal the gap between the lock buckle and the inner side wall of the channel.

[0023] In this way, the first sealing member can be connected to the lock buckle by using the connecting portion, which can simplify the structure of the first sealing member. The connecting portion is sleeved on the outer peripheral side of the lock buckle, which can increase the connection area between the connecting portion and the lock buckle, increase the friction resistance between the lock buckle and the connecting portion, and improve the connection stability between the lock buckle and the sealing member.

[0024] Furthermore, the sealing part is arranged on the outer peripheral side of the connecting part so that the sealing part can seal the circumferential gap between the lock buckle and the inner wall of the channel, thereby increasing the sealing area of ​​the gap by the sealing part and further improving the sealing effect of the first sealing member on the gap.

[0025] In a possible implementation, the first sealing member further includes a connecting member; a through hole is provided on the lock buckle, the connecting member is inserted into the through hole, and two ends of the connecting member in an extending direction are respectively connected to two inner side walls opposite to the connecting portion.

[0026] In this way, by using a connecting piece to pass through the through hole and connecting the two ends of the connecting piece in the extension direction to the connecting part, the connection stability between the connecting part and the lock buckle can be improved, thereby improving the connection stability between the first sealing piece and the lock buckle and reducing the probability of the first sealing piece falling off the lock buckle.

[0027] In a possible implementation, a driving mechanism is further included, which is connected to the lock; the driving mechanism is used to drive the lock to move toward the cover plate to lock the cover plate; or to drive the lock to move away from the cover plate to unlock the cover plate.

[0028] In this way, by using a driving mechanism connected to the lock, the lock can be driven by the driving mechanism to move and the cover plate can be locked and unlocked, which can improve the automation level of the process of locking and unlocking the cover plate by the lock, and can also improve the automation level of the valve assembly.

[0029] In a possible implementation, the driving mechanism includes a driving member and a transmission member;

[0030] The transmission member is connected to the lock catch, and the driving member is drivingly connected to the transmission member. The driving member drives the transmission member to rotate, and drives the lock catch to move toward the cover plate or away from the cover plate through the transmission member.

[0031] In this way, the driving mechanism drives the transmission member to rotate through the driving member, and further drives the lock to move toward or away from the cover plate through the transmission member, which can simplify the structure of the driving mechanism, facilitate the assembly and manufacture of the sewage tank, reduce the manufacturing cost of the sewage tank, and reduce the manufacturing cost of the cleaning equipment and the cleaning system.

[0032] In a possible implementation, the transmission member includes a rotating part, a swing arm and a driving part; the rotating part is rotatably connected to the bottom of the box; one end of the swing arm is connected to the rotating part, and the other end of the swing arm is connected to the driving part, the lock is arranged on the swing arm, and the lock is located between the rotating part and the driving part; the driving part is drivingly connected to the driving member.

[0033] In this way, the transmission member is rotatably connected to the bottom of the box body through the rotating part, the swing arm is connected to the lock, and the driving part is drivingly connected to the driving member, so that the transmission member can drive the lock to move toward the cover plate to lock the cover plate during rotation, and unlock the cover plate when moving away from the cover plate.

[0034] In a possible implementation, the valve assembly further includes a rotating shaft; the rotating shaft is disposed through one end of the cover plate, and the cover plate is rotatably connected to the bottom of the box body through the rotating shaft.

[0035] In this way, by providing a rotating shaft to allow the cover plate to rotate relative to the bottom of the box body, the cover plate can be easily opened or sealed to facilitate the use of the sewage outlet, thereby improving the convenience of the valve assembly. In addition, since the opening and closing method of the cover plate is relatively simple, the manufacturing cost of the valve assembly can be reduced, thereby reducing the manufacturing cost of the sewage tank.

[0036] In a possible implementation, the sewage tank further includes a third sealing member; a through hole for the shaft to pass through is provided between the bottom of the tank body and the valve bracket; the third sealing member is penetrated through the shaft and is used to seal the through hole.

[0037] In this way, by sleeved the third sealing member on the rotating shaft and using the third sealing member to seal the through hole, the probability of sewage in the box body leaking through the gap between the rotating shaft and the through hole can be reduced during positive pressure sewage discharge, thereby improving the sealing performance of the sewage tank during positive pressure sewage discharge, thereby improving the sealing performance and usage experience of the cleaning equipment and cleaning system.

[0038] In a possible implementation, the bottom of the box body has a support frame, and the support frame has a first groove; the first groove and the valve bracket form the through hole.

[0039] In this way, when the valve bracket is connected to the bottom of the box body, the first groove on the support frame and the valve bracket are used to form a through hole, which can support the rotating shaft and improve the support stability of the rotating shaft. On the other hand, since the through hole is formed by the combination of the valve bracket and the support frame, it is easy to disassemble, install and maintain the rotating shaft, thereby improving the convenience of using the sewage tank.

[0040] In a possible implementation manner, a second groove is provided on the valve support at a position corresponding to the first groove; and the first groove and the second groove form the through hole.

[0041] In this way, by setting a second groove corresponding to the first groove on the valve bracket, a through hole is formed by the first groove and the second groove, and the rotating shaft can be located in the through hole formed by the first groove and the second groove, so that the inner edges of the first groove and the second groove can be more closely fitted to the outer wall of the rotating shaft, so as to facilitate the rotation of the rotating shaft relative to the through hole.

[0042] In a possible implementation, a sidewall of the through opening is provided with an avoidance groove through which the rotating shaft can pass, and the third sealing member is located between the avoidance groove and the through hole; the third sealing member abuts against the sidewall of the through hole facing the avoidance groove.

[0043] In this way, by arranging the third seal between the avoidance groove and the through hole, the third seal can be arranged on the side of the through hole facing the avoidance groove, and the gap between the rotating shaft and the through hole is sealed, thereby reducing the probability of sewage entering the through hole through the avoidance groove and further leaking from the through hole to the outside of the box, thereby improving the sealing performance of the connection between the rotating shaft and the through hole.

[0044] In a possible implementation, a clamping hole is further provided between the bottom of the box body and the valve bracket; the clamping hole is clamped to the outer peripheral side of the third sealing member; and the clamping hole is located between the through hole and the avoidance groove.

[0045] In this way, by using the clamping hole to clamp the outer peripheral side of the third seal, the third seal can be further fixed, reducing the radial and axial movement of the third seal in the clamping hole, and improving the installation stability of the third seal in the sewage tank.

[0046] Furthermore, by setting the clamping hole between the through hole and the avoidance groove, and clamping the third seal through the clamping hole, the probability of sewage leaking from the avoidance groove flowing into the through hole during positive pressure sewage discharge can be further reduced, thereby improving the sealing performance at the through hole, and thereby improving the sealing performance of the sewage tank during positive pressure sewage discharge.

[0047] In a possible implementation, the bottom of the box body also has a first slot; the valve bracket has a second slot corresponding to the first slot; the notches of the first slot and the second slot are opposite and are jointly clamped on the outer peripheral side of the third sealing member.

[0048] In this way, by using the first card groove at the bottom of the box body and the second card groove on the valve bracket to form a clamping hole, the installation and replacement of the third seal in the clamping hole can be facilitated, thereby improving the convenience of use of the sewage tank, and thereby improving the convenience and user experience of the cleaning equipment and cleaning system.

[0049] In a possible implementation, the valve bracket also includes two first baffles and second baffles that are spaced apart and arranged in parallel; the first baffle and the second baffle are arranged between the second groove and the avoidance groove; and the first baffle, the second baffle, the wall surface where the second groove is located, and the outer wall surface of the through opening together form a accommodating cavity; the heights of the first baffle and the second baffle are both higher than the bottom of the avoidance groove, and the heights of the first baffle and the second baffle are also higher than the bottom of the second groove.

[0050] In this way, by setting the first baffle and the second baffle, and making the first baffle, the second baffle, the wall where the second groove is located and the outer wall of the opening together form a accommodating chamber, the accommodating chamber can accommodate sewage leaked from the avoidance groove to the outside of the through hole, which can reduce the probability of sewage further leaking into the cleaning equipment, and improve the sealing performance of the sewage tank.

[0051] Furthermore, by making the height of the first baffle plate and the second baffle plate both smaller than the bottom of the avoidance groove, and making the height of the first baffle plate and the second baffle plate both smaller than the bottom of the second groove, the amount of sewage that can be accommodated in the accommodating chamber can be increased, further reducing the probability of sewage leakage to the cleaning equipment, and further improving the sealing performance of the sewage tank.

[0093] As described in the background technology, the prior art uses the gravity of the waste in the sewage tank to discharge the waste; however, this direct gravity discharge of waste has low discharge efficiency, and the sewage pipe is prone to blockage during the discharge process, affecting the user experience of the cleaning equipment and the cleaning system.

[0094] Based on this, the present application can effectively improve the discharge efficiency of waste in the sewage tank by increasing pressure during positive sewage discharge, and can easily discharge stains or residues in the box under the action of positive pressure, so as to keep the inside of the box clean and avoid solid waste clogging the sewage pipe during the sewage discharge process.

[0095] However, there is a risk of sewage leakage during the positive pressure sewage discharge process. The reason for this problem is that when the sewage tank uses positive pressure sewage discharge to discharge sewage, the water pressure at the sewage outlet is relatively high. Although it can accelerate the discharge of sewage, when the water pressure is high, the sewage will be squeezed out from the gap between the lock and the valve bracket, causing sewage leakage. In addition, due to the high water pressure of the sewage flowing out of the sewage outlet during the positive pressure drainage process, the sewage will also leak from the joint between the sewage outlet and the opening on the valve assembly for sewage to pass through, thereby affecting the sealing effect of the sewage tank and the user experience of the cleaning equipment and cleaning system using the sewage tank.

[0096] Furthermore, in response to the above-mentioned technical problems, an embodiment of the present application provides a sewage tank, which can seal the sewage outlet by using a cover plate and a lock in the valve assembly to prevent sewage from leaking from the sewage outlet when sewage discharge is not required, and can open the sewage outlet when positive pressure sewage discharge is required, so as to speed up the efficiency of sewage discharge from the tank through the sewage outlet, and can easily discharge stains or residues in the tank under the action of positive pressure to keep the inside of the tank clean.

[0097] Furthermore, by arranging a first seal at the lock, it can be achieved that during positive pressure sewage discharge, after the lock unlocks the cover plate, the lock and the channel are sealed, thereby preventing sewage from leaking from the joint between the port on the valve bracket and the channel during positive pressure sewage discharge in the sewage tank, for example, sewage from leaking from the gap between the port and the channel, thereby improving the user experience of the cleaning equipment and the cleaning system.

[0098] In addition, since the probability of sewage leaking between the lock buckle and the channel is reduced, the efficiency of sewage being discharged from the cleaning equipment through the sewage outlet and the through port can be improved.

[0099] Furthermore, by arranging a second sealing member on the outer peripheral side of the sewage outlet, the end of the through port facing the sewage outlet can be indirectly connected with the docking point of the sewage outlet through the second sealing member, so that the docking point between the through port and the sewage outlet can be sealed by the second sealing member, which can reduce the probability of sewage leakage from the docking point between the through port and the sewage outlet, improve the sealing effect at the sewage outlet, reduce the risk of sewage leakage, and further improve the user experience of the cleaning equipment and the cleaning system.

[0100] 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.

[0101] refer to Figure 1 , Figure 2 and Figure 3 The embodiment of the present application provides a sewage tank 10, which may include a tank body 100, a valve bracket 200, a valve assembly 300, a first seal 400 and a second seal 500. The sewage tank 10 may be disposed on a cleaning device, and may be used to store sewage after the cleaning device cleans a floor brush.

[0102] refer to Figure 1The box 100 can be used to store sewage after cleaning the floor brush, and the sewage after cleaning the floor brush flows into the box 100 under the action of positive pressure. The bottom of the box 100 has a sewage outlet 110, and the sewage flowing into the sewage tank 10 by positive pressure can be further discharged through the sewage outlet 110 at the bottom of the box 100.

[0103] The embodiment of the present application provides a sewage tank 10, which can seal the sewage outlet 110 by using the cover plate 310 and the lock 320 in the valve assembly 300, so as to prevent sewage from leaking from the sewage outlet 110 when sewage discharge is not required, and can open the sewage outlet 110 when positive pressure sewage discharge is required, so as to accelerate the efficiency of sewage discharge from the box body 100 through the sewage outlet 110, and can conveniently discharge the stains or residues in the box body 100 under the action of positive pressure to keep the inside of the box body 100 clean. The present application can effectively improve the discharge efficiency of the dirt in the sewage tank 10 by adopting positive pressure sewage discharge, and can conveniently discharge the stains or residues in the box body 100 under the action of positive pressure to keep the inside of the box body 100 clean and avoid solid garbage blocking the sewage pipe during sewage discharge.

[0104] refer to Figure 2 , Figure 3 and Figure 4 The valve bracket 200 is arranged at the bottom of the box 100 and has a through-port 210 at a position opposite to the sewage outlet 110. The valve bracket 200 can be used to connect the bottom of the box 100 with other components on the cleaning equipment. The valve bracket 200 can also be used to support the valve that controls the sewage outlet 110 and provide a movable space for the valve assembly 300. The through-port 210 is arranged opposite to the sewage outlet 110, and the sewage discharged from the sewage outlet 110 is further discharged from the cleaning equipment through the through-port 210.

[0105] The valve assembly 300 may include a cover plate 310 and a lock 320. The cover plate 310 is used to seal the sewage outlet 110, or to open the sewage outlet 110 when the sewage is discharged under positive pressure. The side wall of the through port 210 is provided with a channel 220 for the lock 320 to be movably arranged. The lock 320 is used to lock or unlock the cover plate 310. The lock 320 can move toward the cover plate 310 or away from the cover plate 310 in the channel 220. When the cover plate 310 needs to be locked by the lock 320, the lock 320 moves toward the cover plate 310 in the channel 220. When the cover plate 310 needs to be unlocked by the lock 320, the lock 320 moves away from the cover plate 310 in the channel 220.

[0106] refer to Figure 3 The first sealing member 400 is disposed on the lock buckle 320 . After the lock buckle 320 unlocks the cover plate 310 , the first sealing member 400 seals between the lock buckle 320 and the channel 220 .

[0107] In some embodiments, there is a gap between the lock 320 and the channel 220. When the lock 320 unlocks the cover 310 so that the cover 310 opens the sewage outlet 110, the sewage can leak through the gap between the lock 320 and the channel 220 to the space between the valve bracket 200 and the box body 100, so that the sewage stays in the cleaning equipment and cannot be discharged.

[0108] By providing the first sealing member 400 at the lock buckle 320, it is possible to achieve sealing between the lock buckle 320 and the channel 220 after the lock buckle 320 unlocks the cover plate 310 during positive pressure sewage discharge. This can prevent sewage from leaking from the joint between the through port 210 on the valve bracket 200 and the channel 220 during positive pressure sewage discharge from the sewage tank 10, for example, sewage from leaking from the gap between the through port 210 and the channel 220, thereby improving the user experience of the cleaning equipment and the cleaning system.

[0109] In addition, since the probability of sewage leaking between the lock buckle 320 and the channel 220 is reduced, the efficiency of sewage being discharged from the cleaning equipment through the sewage outlet 110 and the through port 210 can be improved.

[0110] In some embodiments, the first sealing member 400 may be a rubber sealing member. The rubber has a certain elasticity and can seal between the lock buckle 320 and the channel 220 through elastic deformation of the rubber.

[0111] The second sealing member 500 is disposed around the outer circumference of the sewage outlet 110 , and the second sealing member 500 is used to seal the joint between the sewage outlet 110 and the through port 210 .

[0112] In some embodiments, when the valve bracket 200 is connected to the box body 100, there may be a gap at the joint between the end of the through port 210 facing the sewage outlet 110 and the sewage outlet 110. When the sewage tank 10 discharges sewage under positive pressure, the sewage discharged from the sewage outlet 110 may leak through the gap at the joint between the through port 210 and the sewage outlet 110.

[0113] refer to Figure 3 It is understandable that the joint between the sewage outlet 110 and the through-port 210 may not be a direct joint between the end of the sewage outlet 110 and the end of the through-port 210 .

[0114] refer to Figure 3For example, the caliber of the through-port 210 may be larger than the caliber of the sewage outlet 110, so that when the valve bracket 200 is installed at the bottom of the box body 100, the sewage outlet 110 and the through-port 210 are nested, and the sewage outlet 110 is located inside the through-port 210, and the through-port 210 and the sewage outlet 110 partially overlap in the radial direction. There may be a certain distance between the inner peripheral wall of the through-port 210 and the outer peripheral wall of the sewage outlet 110, and at least part of the second sealing structure can be within the gap. The end of the through-port 210 facing the sewage outlet 110 can be abutted against the area around the sewage outlet 110 at the bottom of the box body 100 through the second sealing member 500, thereby reducing the leakage of sewage through the gap between the sewage outlet 110 and the through-port 210.

[0115] By arranging a second seal 500 on the outer peripheral side of the sewage outlet 110, the end of the through port 210 facing the sewage outlet 110 can be indirectly connected with the docking point of the sewage outlet 110 through the second seal 500, so that the docking point between the through port 210 and the sewage outlet 110 can be sealed by the second seal 500, which can reduce the probability of sewage leakage from the docking point between the through port 210 and the sewage outlet 110, improve the sealing effect at the sewage outlet 110, reduce the risk of sewage leakage, and further improve the user experience of the cleaning equipment and the cleaning system.

[0116] In some embodiments, the second sealing member 500 may also be a rubber sealing member. The rubber has a certain elasticity and can seal the joint between the through port 210 and the sewage outlet 110 through the elastic deformation of the rubber.

[0117] refer to Figure 3 In some embodiments, the bottom of the box body 100 has an installation groove 120, which is arranged on the outer peripheral side of the sewage outlet 110. The second sealing member 500 is arranged in the installation groove 120 and is sealed and abutted with the end of the through opening 210 of the valve bracket 200 toward the bottom of the box body 100.

[0118] In this way, by setting the installation groove 120 at the bottom of the box body 100, the groove of the installation groove 120 faces the bottom of the box body 100, and the second sealing member 500 is set in the installation groove 120, the surface of the second sealing member 500 facing the bottom of the box body 100 can contact the bottom of the installation groove 120.

[0119] The side of the second sealing member 500 can also be brought into contact with the side of the mounting groove 120 at the bottom of the housing 100. Under the mutual abutment between the side wall of the mounting groove 120 and the side wall of the second sealing member 500, the probability of the second sealing member 500 being offset or shaken in the height direction perpendicular to the housing 100 is reduced, thereby improving the installation stability of the second sealing member 500, and improving the sealing stability at the through port 210 and the sewage outlet 110, thereby improving the sealing effect of the sewage tank 10.

[0120] refer to Figure 3 and Figure 4 In some embodiments, the valve support 200 has a moving space 230, and two first inner walls 240 opposite to the moving space 230 are provided with a first opening 250 and a second opening 260. The first opening 250 and the second opening 260 can be provided on two first inner walls 240 spaced apart along the moving direction of the lock 320.

[0121] The first opening 250 extends to the inner wall of the through hole 210 and communicates with the through hole 210, and a communicating channel 220 is formed between the first opening 250 and the second opening 260. The first sealing member 400 is located in the moving space 230, and after the lock buckle 320 unlocks the cover plate 310, the first sealing member 400 seals the second opening 260.

[0122] In this way, by setting a moving space 230 on the valve bracket 200 and setting the lock buckle 320 and the first seal 400 in the moving space 230, the lock buckle 320 and the first seal 400 can be protected to prevent the lock buckle 320 and the first seal 400 from being affected by other components, thereby improving the protection of the lock buckle 320 and the first seal 400 and the working stability of the lock buckle 320 and the first seal 400, thereby improving the working stability of the sewage tank 10.

[0123] Furthermore, by connecting the first opening 250 with the through port 210, the lock 320 moves in the channel 220 connected between the first opening 250 and the second opening 260, and after the lock 320 unlocks the cover plate 310, the first seal 400 seals the second opening 260, thereby preventing sewage from entering the moving space 230 and the channel 220 through the connection between the first opening 250 and the through port 210, and further leaking from the second opening 260 to the outside of the valve bracket 200, thereby reducing the risk of sewage leakage.

[0124] refer to Figure 3 and Figure 4 The moving space 230 also has two second inner walls perpendicular to the first inner wall 240 . The two second inner walls are arranged opposite to each other, and the first sealing member 400 does not contact the second inner walls.

[0125] In this way, by preventing the first seal 400 from contacting the two opposite second inner walls in the moving space 230, the first seal 400 can be prevented from contacting the second inner wall during the process of the lock buckle 320 driving the first seal 400 to move in the channel 220, thereby preventing the sliding friction resistance generated by the contact between the first seal 400 and the second inner wall from affecting the movement of the second seal 500, and preventing the wear caused by the sliding friction between the first seal 400 and the second inner wall, thereby improving the stability of the movement process of the lock buckle 320 and the first seal 400, reducing the wear of the first seal 400 and increasing the service life of the first seal 400.

[0126] In another possible implementation, a first opening 250 is formed on the side wall of the through opening 210 , and the first opening 250 forms a channel 220 . The first sealing member 400 is located in the through opening 210 . After the lock 320 unlocks the cover 310 , the first sealing member 400 seals the first opening 250 .

[0127] In this way, by forming the channel 220 through the first opening 250, the lock 320 can move in the first opening 250, and the first seal 400 is located in the through opening 210, so that after the lock 320 unlocks the cover plate 310, the first seal 400 seals the first opening 250 from the inside of the through opening 210 to prevent sewage in the through opening 210 from leaking through the first opening 250, thereby improving the sealing effect.

[0128] refer to Figure 3 and Figure 5 In some embodiments, the first sealing member 400 may include a connecting portion 410 and a sealing portion 420. The connecting portion 410 is sleeved on the outer peripheral side of the lock buckle 320, and the sealing portion 420 is disposed on the outer peripheral side of the connecting portion 410. The sealing portion 420 is used to seal the gap between the lock buckle 320 and the inner side wall of the channel 220.

[0129] In some embodiments, the sealing portion 420 may be a flange-shaped sealing structure disposed on the outer circumference of the connecting portion 410 .

[0130] In this way, the first sealing member 400 can be connected to the lock buckle 320 by using the connecting portion 410, so that the structure of the first sealing member 400 can be simplified. The connecting portion 410 is sleeved on the outer peripheral side of the lock buckle 320, which can increase the connection area between the connecting portion 410 and the lock buckle 320, increase the friction resistance between the lock buckle 320 and the connecting portion 410, and improve the connection stability between the lock buckle 320 and the sealing portion 420.

[0131] Furthermore, the sealing portion 420 is arranged on the outer peripheral side of the connecting portion 410 so that the sealing portion 420 can seal the circumferential gap between the lock buckle 320 and the inner wall of the channel 220, thereby increasing the sealing area of ​​the gap by the sealing portion 420 and further increasing the sealing effect of the first sealing member 400 on the gap.

[0132] refer to Figure 5 In some embodiments, the first sealing member 400 may further include a connecting member 430. The connecting portion 410 may be annular, a through hole 330 is provided on the lock buckle 320, the connecting member 430 is passed through the through hole 330, and the two ends of the connecting member 430 in the extending direction are respectively connected to the two inner side walls opposite to the connecting portion 410.

[0133] In this way, by using the connecting piece 430 to pass through the through hole 330 and connecting the two ends of the connecting piece 430 in the extension direction to the connecting part 410, the connection stability between the connecting part 410 and the lock buckle 320 can be improved, thereby improving the connection stability between the first sealing piece 400 and the lock buckle 320 and reducing the probability of the first sealing piece 400 falling off the lock buckle 320.

[0134] refer to Figure 5 and Figure 6 In some embodiments, the sewage tank 10 may further include a driving mechanism 600, which is connected to the lock buckle 320, and is used to drive the lock buckle 320 to move toward the cover plate 310 to lock the cover plate 310. Alternatively, the driving mechanism 600 is used to drive the lock buckle 320 to move away from the cover plate 310 to unlock the cover plate 310.

[0135] In this way, by using the driving mechanism 600 to connect with the lock 320, the lock 320 can be driven to move by the driving mechanism 600, and the cover 310 can be locked and unlocked, which can improve the automation level of the process of locking and unlocking the cover 310 by the lock 320, and can also improve the automation level of the valve assembly 300.

[0136] In some embodiments, the driving mechanism 600 can drive the lock catch 320 to move along a straight line to unlock and lock the cover plate 310. The driving mechanism 600 can also drive the lock catch 320 to move along an arc-shaped trajectory to unlock and lock the cover plate 310.

[0137] refer to Figure 6In some embodiments, the driving mechanism 600 may include a driving member and a transmission member 610. The transmission member 610 is connected to the lock buckle 320, and the driving member is drivingly connected to the transmission member 610. The driving member drives the transmission member 610 to rotate, and drives the lock buckle 320 to move toward or away from the cover plate 310 through the transmission member 610. The transmission member 610 rotates and can drive the lock buckle 320 to move along an arc-shaped trajectory to unlock and lock the cover plate 310.

[0138] In this way, the driving mechanism 600 drives the transmission member 610 to rotate through the driving member, and further drives the lock buckle 320 to move toward the cover plate 310 or away from the cover plate 310 through the transmission member 610, which can simplify the structure of the driving mechanism 600, facilitate the assembly and manufacture of the sewage tank 10, reduce the manufacturing cost of the sewage tank 10, and reduce the manufacturing cost of the cleaning equipment and the cleaning system.

[0139] refer to Figure 6 On the basis of the above embodiment, the transmission member 610 may include a rotating portion 611, a swing arm 612 and a driving portion 613. The rotating portion 611 is rotatably connected to the bottom of the box body 100. One end of the swing arm 612 is connected to the rotating portion 611, and the other end of the swing arm 612 is connected to the driving portion 613. The lock buckle 320 is provided on the swing arm 612, and the lock buckle 320 is located between the rotating portion 611 and the driving portion 613. The driving portion 613 is drivingly connected to the driving member.

[0140] In this way, the transmission member 610 is rotatably connected to the bottom of the box body 100 through the rotating part 611, the swing arm 612 is connected to the lock buckle 320, and the driving part 613 is drivingly connected to the driving member, so that the transmission member 610 can drive the lock buckle 320 to lock the cover plate 310 when it moves toward the cover plate 310 during rotation, and unlock the cover plate 310 when it moves away from the cover plate 310. The structure of the transmission member 610 can be simplified, making it easier for the transmission member 610 to drive the lock buckle 320 to lock or unlock the cover plate 310.

[0141] Continue to refer Figure 6 In some embodiments, the valve assembly 300 may further include a rotating shaft 340 , which is disposed through one end of the cover plate 310 , and the cover plate 310 is rotatably connected to the bottom of the box body 100 through the rotating shaft 340 .

[0142] In this way, by providing the rotating shaft 340 to allow the cover plate 310 to rotate relative to the bottom of the box body 100, the cover plate 310 can be conveniently opened or sealed to the sewage outlet 110, thereby improving the convenience of use of the valve assembly 300. In addition, since the opening and closing method of the cover plate 310 is relatively simple, the manufacturing cost of the valve assembly 300 can be reduced, thereby reducing the manufacturing cost of the sewage tank 10.

[0143] On the basis of the above embodiment, the valve assembly 300 may further include a reset structure 350. The reset structure 350 is connected to the rotating shaft 340, and the reset structure 350 is used to drive the rotating shaft 340 to rotate so as to reset the cover plate 310.

[0144] In this way, by using the reset structure 350 connected to the rotating shaft 340, after the positive pressure sewage discharge is completed, the reset structure 350 can drive the cover plate 310 to seal the sewage outlet 110 in the open state again, which can facilitate the cover plate 310 to seal the sewage outlet 110, thereby improving the convenience of use of the valve assembly 300, and further improving the convenience of use of the sewage tank 10.

[0145] In some embodiments, the reset structure 350 can be a torsion spring. During positive pressure sewage discharge, the torsion spring twists and deforms and generates a torsional force. When the positive pressure sewage discharge ends, the impact force of the sewage disappears. Under the action of the torsion force, the torsion spring drives the cover plate 310 to rotate toward the sewage outlet 110 and seals the sewage outlet 110.

[0146] refer to Figure 6 and Figure 7 In some embodiments, the sewage tank 10 may further include a third sealing member 700. A through hole 130 is provided between the bottom of the tank body 100 and the valve bracket 200 for the shaft 340 to pass through. The third sealing member 700 is disposed on the shaft 340 and is used to seal the through hole 130.

[0147] In some embodiments, there may be two through holes 210, the cover plate 310 is located between the two through holes 130, and the rotating shaft 340 passes through the through hole 130, the cover plate 310, and another through hole 130 at one time. The stability of the cover plate 310 during rotation can be improved, and the connection stability between the cover plate 310 and the bottom of the box body 100 and the valve bracket 200 can be improved. When there are two through holes 130, there may also be two third sealing members 700, and the two third sealing members 700 are used to seal the two through holes 130 respectively.

[0148] In this way, by sleeved the third seal 700 on the rotating shaft 340 and using the third seal 700 to seal the through hole 130, during positive pressure sewage discharge, the probability of sewage in the box body 100 leaking from the gap between the rotating shaft 340 and the through hole 130 can be reduced, thereby improving the sealing performance of the sewage tank 10 during positive pressure sewage discharge, thereby improving the sealing performance and user experience of the cleaning equipment and cleaning system.

[0149] In some embodiments, the third sealing member 700 may be a rubber ring, which is sleeved on the rotating shaft 340 and can be used to seal the gap between the rotating shaft 340 and the through hole 130 .

[0150] refer to Figure 7 and Figure 8In some embodiments, the bottom of the box body 100 has a support frame 140 , and the support frame 140 has a first groove 141 . The first groove 141 and the valve bracket 200 form a through hole 130 .

[0151] In this way, when the valve bracket 200 is connected to the bottom of the box body 100, the first groove 141 on the support frame 140 and the valve bracket 200 are used to form the through hole 130, which can support the rotating shaft 340 and improve the support stability of the rotating shaft 340. On the other hand, since the through hole 130 is formed by the combination of the valve bracket 200 and the support frame 140, it is convenient to disassemble, install and maintain the rotating shaft 340, thereby improving the convenience of use of the sewage tank 10.

[0152] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, a second groove 270 is disposed on the valve support 200 at a position corresponding to the first groove 141 , and the first groove 141 and the second groove 270 form a through hole 130 .

[0153] In this way, by setting the second groove 270 corresponding to the first groove 141 on the valve bracket 200, the through hole 130 is formed by the first groove 141 and the second groove 270, and the rotating shaft 340 can be located in the through hole 130 formed by the first groove 141 and the second groove 270, so that the inner edges of the first groove 141 and the second groove 270 can be more closely fitted to the outer wall of the rotating shaft 340, so as to facilitate the rotating shaft 340 to rotate relative to the through hole 130.

[0154] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, a sidewall of the through opening 210 is provided with an avoidance groove 280 for the shaft 340 to pass through, and the third seal 700 is located between the avoidance groove 280 and the through hole 130 , and the third seal 700 abuts against the sidewall of the through hole 130 facing the avoidance groove 280 .

[0155] In this way, by setting the third sealing member 700 between the avoidance groove 280 and the through hole 130, the third sealing member 700 can be set on the side of the through hole 130 facing the avoidance groove 280, and the gap between the rotating shaft 340 and the through hole 130 is sealed, thereby reducing the probability of sewage entering the through hole 130 through the avoidance groove 280 and further leaking from the through hole 130 to the outside of the box body 100, thereby improving the sealing performance of the connection between the rotating shaft 340 and the through hole 130.

[0156] refer to Figure 4 , Figure 7 and Figure 8In some embodiments, a clamping hole 150 is further provided between the bottom of the box body 100 and the valve support 200 . The clamping hole 150 is clamped to the outer peripheral side of the third sealing member 700 , and the clamping hole 150 is located between the through hole 130 and the avoidance groove 280 .

[0157] In this way, by using the clamping hole 150 to clamp the outer peripheral side of the third seal 700, the third seal 700 can be further fixed, reducing the radial and axial movement of the third seal 700 in the clamping hole 150, and improving the installation stability of the third seal 700 in the sewage tank 10.

[0158] Furthermore, by setting the clamping hole 150 between the through hole 130 and the avoidance groove 280, and clamping the third sealing member 700 through the clamping hole 150, the probability of sewage leaking from the avoidance groove 280 flowing to the through hole 130 during positive pressure sewage discharge can be further reduced, thereby improving the sealing performance at the through hole 130, and further improving the sealing performance of the sewage tank 10 during positive pressure sewage discharge.

[0159] refer to Figure 4 , Figure 7 and Figure 8 In some embodiments, the bottom of the box body 100 further has a first slot 160 . The valve bracket 200 has a second slot 290 corresponding to the first slot 160 . The first slot 160 and the second slot 290 are opposite to each other and are clamped together on the outer peripheral side of the third sealing member 700 .

[0160] In this way, by using the first card groove 160 at the bottom of the box body 100 and the second card groove 290 on the valve bracket 200 to form a clamping hole 150, the third sealing member 700 can be easily installed and replaced in the clamping hole 150, thereby improving the convenience of use of the sewage tank 10, and further improving the convenience and user experience of the cleaning equipment and the cleaning system.

[0161] refer to Figure 4 In some embodiments, the valve support 200 may further include a first baffle 290a and a second baffle 290b that are spaced apart and arranged in parallel. The first baffle 290a and the second baffle 290b are arranged between the second groove 270 and the avoidance groove 280. The first baffle 290a, the second baffle 290b, the wall surface where the second groove 270 is located, and the outer wall surface of the through opening 210 together form the accommodating chamber 170.

[0162] In this way, by setting the first baffle 290a and the second baffle 290b, and making the first baffle 290a, the second baffle 290b, the wall where the second groove 270 is located, and the outer wall of the opening 210 together form a accommodating chamber 170, the accommodating chamber 170 can accommodate sewage leaked from the avoidance groove 280 to the outside of the through hole 130, which can reduce the probability of sewage further leaking into the cleaning equipment, and improve the sealing performance of the sewage tank 10.

[0163] The heights of the first baffle 290 a and the second baffle 290 b are both higher than the bottom of the avoidance groove 280 , and the heights of the first baffle 290 a and the second baffle 290 b are also higher than the bottom of the second groove 270 .

[0164] By making the heights of the first baffle 290a and the second baffle 290b smaller than the bottom of the avoidance groove 280, and making the heights of the first baffle 290a and the second baffle 290b smaller than the bottom of the second groove 270, the amount of sewage that can be accommodated in the accommodating chamber 170 can be increased, the probability of sewage leakage to the cleaning equipment can be further reduced, and the sealing performance of the sewage tank 10 can be further improved.

[0165] refer to Fig. 9 In some embodiments, the bottom of the box 100 has an installation area for the second sealing member 500, and the support frame 140 is located in the installation area. The second sealing member 500 is provided with an avoidance hole 510 for avoiding the support frame 140.

[0166] Thus, by providing the avoidance hole 510 in the area corresponding to the support frame 140 on the second sealing member 500 , the installation and replacement of the second sealing member 500 can be facilitated, the assembly efficiency of the second sealing member 500 can be improved, and the assembly efficiency of the sewage tank 10 can be improved.

[0167] refer to Fig.10 and Fig.11 On the basis of the above embodiment, the embodiment of the present application further provides a cleaning device 10, which may include a body and a sewage tank 10 disposed on the body. The body may also include a floor brush, and the sewage after cleaning the floor brush can be transported to the sewage tank 10 under the action of positive pressure, and further discharged from the sewage tank 10 to the outside of the cleaning device 10. The sewage tank 10 can be used to store sewage for cleaning the floor brush assembly 22.

[0168] The embodiment of the present application provides a cleaning device 10. By using the above-mentioned sewage tank 10, the probability of sewage in the sewage tank 10 leaking into the cleaning device 10 during the positive pressure sewage discharge process can be reduced, the sealing performance of the cleaning device 10 is improved, and the user experience of the cleaning device 10 can be improved.

[0169] refer to Figure 3 and Fig.11On the basis of the above embodiments, the embodiments of the present application further provide a cleaning system, which may include a base station 30, a cleaning device 20 and a sewage pipe 31, wherein one end of the sewage pipe 31 is connected to the cleaning device 20, and the other end is connected to the base station 30.

[0170] The wind provided by the fan 32 enters the sewage tank 10, so that a positive pressure is formed in the sewage tank 10, and then the sewage in the sewage tank 10 is discharged under the action of the positive pressure. Specifically, the sewage in the sewage tank 10 is discharged from the sewage outlet 110 on the sewage tank 10 through the sewage pipe 31 on the fuselage and the base station 30.

[0171] The present application provides a cleaning system. By using the above-mentioned cleaning device 10, the cleaning system can reduce the amount of sewage leaked from the cleaning device 10 to the base station 30 during the positive pressure sewage discharge process, thereby improving the user experience of the cleaning system.
