Abstract

The embodiment of the present application provides a sewage tank of a cleaning device, the cleaning device and a cleaning system. The sewage tank comprises a tank cover module, a tank body and a resistance piece. The tank cover module and the tank body enclose a sewage storage cavity. The tank cover module has a suction port communicating with the sewage storage cavity. The tank body has a sewage inlet pipe capable of sucking external dirt into the sewage storage cavity under a negative pressure environment. The resistance piece is rotationally arranged on the tank cover module and has a resistance position and an open position when rotating. When the resistance piece is in the resistance position, part of the dirt can be blocked from moving towards the suction port, and when the resistance piece is in the open position, the dirt flowing between the resistance piece and the tank cover module can be collected on one side of the resistance piece towards the inner bottom wall of the sewage storage cavity. When the sewage tank is in a lying state, the resistance piece can be stressed by the surge of the dirt to cyclically switch between the resistance position and the open position, so that when the sewage tank is applied to the cleaning device, the surge of the dirt can be effectively inhibited, and the risk of damage to the liquid inlet of the suction device in the cleaning device can be reduced.

Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a wastewater tank, cleaning equipment, and cleaning system for a cleaning device. Background Technology

[0002] Cleaning equipment is a device capable of automatically cleaning surfaces and is widely used in people's daily lives and work. For example, cleaning equipment can include floor scrubbers. When cleaning equipment cleans a surface, the suction device sucks up the dirt and temporarily stores it in a wastewater tank, thus achieving the automatic cleaning function.

[0003] To meet the cleaning needs of low-ceilinged spaces, the cleaning equipment is equipped with a horizontal operation function. When in horizontal operation, the cleaning equipment can be used in a nearly parallel position to the surface to be cleaned. In this position, since both the wastewater tank and the suction device are mounted on the main body, they are close to the surface. When the cleaning equipment is in this horizontal position, the user will move it back and forth on the surface. The wastewater in the tank contains a large amount of dirty water, which will cause the wastewater to shake violently due to the movement of the cleaning equipment, creating a "surge" phenomenon. This surge will cause significant fluctuations in the liquid level in the wastewater tank, even splashing droplets. Because the suction port of the wastewater tank is connected to the suction device, splashed droplets are more likely to rush into the suction device through the suction port, significantly increasing the risk of damage to the suction device due to liquid ingress.

[0004] Therefore, how to suppress the surge generated in the sewage tank when the cleaning equipment is used horizontally and reduce the risk of damage to the suction device has become a technical problem to be solved. Utility Model Content

[0005] This application provides a wastewater tank, cleaning equipment, and cleaning system for a cleaning device, which can suppress surges generated in the wastewater tank when the cleaning equipment is used lying flat, reducing the risk of damage to the suction device due to liquid ingress.

[0006] In a first aspect, embodiments of this application provide a wastewater tank for a cleaning device used to clean surfaces to be cleaned. The wastewater tank includes:

[0007] The box has a sewage inlet pipe and a first side wall in the circumferential direction;

[0008] The lid module has a suction port; the lid module is located on the top of the box and is assembled with the box to form a sludge storage chamber; the suction port is connected to the sludge storage chamber and is used to extract the gas in the sludge storage chamber to create a negative pressure environment in the sludge storage chamber; the outlet end of the sludge inlet pipe is located in the sludge storage chamber, and the sludge inlet pipe serves as a channel to suck external dirt into the sludge storage chamber under negative pressure.

[0009] The blocking component is rotatably mounted on the cover module. The blocking component is used to prevent some of the dirt in the dirt storage chamber from moving toward the suction port. The blocking component has a blocking position and an open position when it rotates relative to the dirt inlet pipe. During the process of the blocking component rotating from the open position to the blocking position, the gap between the blocking component and the first side wall gradually decreases, and the distance between the free end of the blocking component and the dirt storage chamber on the inner bottom wall gradually increases.

[0010] The sewage tank can be used in both upright and horizontal positions.

[0011] When the wastewater tank is in an upright position, the tank body and the tank cover module are arranged in a direction perpendicular to the surface to be cleaned;

[0012] When the wastewater tank is in a horizontal position, the tank body and lid module are positioned parallel to the surface to be cleaned, with the first sidewall adjacent to the surface. The stop is designed to rotate under the influence of dirt within the storage chamber, allowing it to switch between a stopped position and an open position. During user operation, the wastewater tank is pulled and pushed, causing the dirt within the storage chamber to move back and forth under inertia and the combined pushing and pulling forces, thus driving the stop to rotate. The dirt is actually a solid-liquid mixture, such as wastewater containing hair and sunflower seed shells.

[0013] When the wastewater tank of the cleaning equipment provided in this application embodiment is in a flat position, the first sidewall is adjacent to the surface to be cleaned. Under the action of gravity or the inertia of dirt flowing towards the tank cover module, the blocking member will rotate from the open position to the blocking position. During the process of the blocking member rotating from the open position to the blocking position, the gap between the blocking member and the first sidewall gradually decreases, and the distance between the free end of the blocking member and the wastewater storage cavity on the inner bottom wall gradually increases. This setting makes the blocking member closer to the first sidewall in the wastewater storage cavity and rotates towards the side closer to the tank cover module. This allows the blocking member to better prevent some of the dirt in the wastewater storage cavity from moving towards the suction port when it is in the blocking position. Therefore, when the wastewater tank is used in the cleaning equipment, it can reduce the risk of dirt moving towards the suction port and entering the suction device when the cleaning equipment is in the flat position.

[0014] Furthermore, the stop member is configured to switch between a stopped position and an open position driven by dirt in the dirt storage chamber. When the wastewater tank is used with the cleaning equipment and the cleaning equipment is moved back and forth by the user in a flat position, the dirt in the wastewater tank may move towards the suction port side under the action of inertia and cause a surge. This drives the stop member to switch from the open position to the stopped position, so that the stop member can block some of the dirt from moving towards the suction port side. While suppressing the surge, it can also block some of the dirt on the side of the stop member facing the bottom wall of the dirt storage chamber, thereby reducing the risk of dirt entering the suction device through the suction port and thus reducing the risk of liquid damage to the suction device.

[0015] When dirt from the wastewater tank flows into the area between the retaining member and the tank cover module, as the cleaning equipment is moved back and forth by the user in its lying position, this dirt may also move towards the inner bottom wall of the wastewater storage chamber due to inertia, causing a surge that drives the retaining member to switch from the blocked position to the open position. At this time, as the gap between the retaining member and the first side wall gradually increases, this dirt will again be collected on the side of the retaining member facing the inner bottom wall of the wastewater storage chamber.

[0016] Therefore, by setting up a baffle in the wastewater tank, when the cleaning equipment is in a lying position and is moved back and forth by the user, the baffle will cycle between the baffle position and the open position driven by the dirt in the wastewater storage chamber. This achieves surge suppression, reduces the risk of damage to the suction device from liquid ingress, simplifies the structure of the wastewater tank, and gathers solid dirt in the wastewater tank to the side of the baffle facing the wastewater storage chamber on the inner bottom wall. This reduces the probability of solid dirt adhering to the tank cover module, making it convenient for users to empty the wastewater tank along with the dirt when cleaning it, reducing the time users spend cleaning the wastewater tank, and improving cleaning efficiency and user experience.

[0017] In some embodiments, when the stop member rotates, it abuts against the circumferential outer wall of the inlet pipe to reach the open position. This limits the maximum rotation angle of the stop member through the inlet pipe, ensuring that when the stop member is in the open position, a dimensionally stable return channel is formed between the stop member and the first side wall. This also limits the maximum rotation angle of the stop member, preventing it from rotating excessively under the influence of dirt, thus preventing it from switching to the open position under the drive of dirt. This ensures the stability of the stop member's position switching under different operating conditions.

[0018] In some embodiments, the abutment has a clearance notch on the side facing the inlet pipe to avoid interference between the abutment and the inlet pipe when rotating, ensuring that the abutment can rotate smoothly under the drive of dirt, so as to effectively suppress surges.

[0019] When in the open position, at least part of the clearance notch abuts against the circumferential outer wall of the sewage inlet pipe. This ensures that when the stop is in the open position, it can fit tightly against the circumferential outer wall of the sewage inlet pipe, ensuring the limiting effect of the sewage inlet pipe on the stop, limiting the maximum opening of the stop after the sewage tank is assembled, and forming a structurally regular return channel between the stop and the first side wall of the sewage tank. This allows the dirt flowing into the area between the stop and the tank cover module to flow back smoothly and accumulate on the side of the stop facing the sewage storage chamber on the inner bottom wall.

[0020] In some embodiments, when the sewage tank is in an upright position, the abutment rotates from a stopped position to an open position under the action of gravity. This gradually increases the gap between the abutment and the first sidewall, allowing solid dirt near the tank cover module to pass through smoothly. Simultaneously, the distance between the free end of the abutment and the sewage storage chamber on the inner bottom wall gradually decreases, connecting the sewage storage chamber with the surrounding area of ​​the sewage inlet pipe and reducing air resistance inside the sewage tank. At the same time, the open position allows the abutment to be in a naturally relaxed state, preventing the structural components from maintaining a stressed posture for extended periods when not in operation.

[0021] In some embodiments, the shape of the free end matches the shape enclosed by the inner wall of the first sidewall. When the stop member rotates to the stop position, the distance between the free end and the inner wall of the first sidewall is 2-4 mm. If this distance is too small, it is easily blocked or jammed by dirt, preventing rotation. If the distance is too large, it significantly weakens the unloading force during the dirt flow process and greatly reduces the surge suppression capability. A balance needs to be struck between these two conditions. After multiple inference calculations and statistical analysis of the solid composition of the dirt, as well as simulation and physical experiments, the optimal range of this distance was obtained. This effectively suppresses dirt surges while ensuring the flexibility of the stop member's rotation, avoiding dirt blockage between the stop member and the first sidewall, thus guaranteeing the reliability of the wastewater tank. When the wastewater tank is used in cleaning equipment, it reduces the risk of damage to the inlet liquid of the suction device within the cleaning equipment.

[0022] In some embodiments, the tank cover module includes a tank cover and a water-blocking component. The suction port is disposed on the tank cover, and the water-blocking component is connected to the bottom end of the tank cover and is positioned inside the sludge storage chamber at the outlet end of the sludge inlet pipe to prevent the dirt output from the sludge inlet pipe from moving toward the suction port. When the sludge inlet pipe draws dirt from the cleaning process of the cleaning equipment into the sludge tank through the outlet end of the sludge inlet pipe under the action of pressure difference, the dirt can directly enter the sludge storage chamber under the obstruction and guidance of the water-blocking component, and thus will not enter the suction device through the suction port.

[0023] The stopper and the water-blocking assembly are rotatably connected. When a surge of dirt occurs in the sewage tank, the dirt is first blocked by the stopper. Some dirt can enter the space between the stopper and the water-blocking assembly through the gap between the stopper and the first side wall. Thus, the water-blocking assembly can block this part of the dirt a second time. This can further enhance the sewage tank's ability to suppress surges. When the sewage tank is used in cleaning equipment, it can further reduce the risk of liquid ingress damage to the suction device in the cleaning equipment.

[0024] In some embodiments, the water-blocking assembly includes a first water-blocking member, which is disposed on the top of the sewage inlet pipe and surrounds the side of the sewage inlet pipe adjacent to the first sidewall in the circumferential direction. When the sewage tank is in operation, the dirt output from the sewage inlet pipe is blocked by the first water-blocking member, which can prevent the dirt from splashing upward to the area near the suction port, thereby reducing the risk of liquid damage to the suction device.

[0025] The stop member is rotatably connected to the first water-blocking member. When the cleaning equipment is used lying flat, the dirt entering the dirt storage chamber can be restricted to the area between the first water-blocking member and the first side wall. At this time, even if some dirt passes over the stop member under strong surge, it will be blocked by the first water-blocking member and cannot enter the space where the suction port is located. When the wastewater tank is used in the cleaning equipment, the risk of liquid inlet damage to the suction device can be further reduced.

[0026] In some embodiments, the water-blocking assembly further includes a surge suppressor connected to the side of the first water-blocking member adjacent to the first sidewall. When a strong surge occurs, if some contaminants pass over the blocking member, the surge suppressor can again block the passing contaminants, further weakening the surge energy and reducing the risk of contaminants continuing to flow towards the suction port. Furthermore, in abnormal situations where the blocking member cannot switch to the blocking position normally due to a malfunction, the surge suppressor can still function as an independent structure, continuing to perform its surge suppression function and improving the fault tolerance of the wastewater tank.

[0027] When the stop component rotates, it abuts against the surge suppressor to reach the stop position. The stop component abuts against the surge suppressor to limit the rotation of the stop component, preventing the stop component from rotating excessively under the impact of dirt, so that it cannot switch to the open position under the drive of dirt, thus ensuring the stability of the stop component's operation.

[0028] In some embodiments, the projection of the surge suppressor onto the abutment is located in the central region of the abutment. The abutment has a sheet-like structure and multiple flow holes, allowing dirt in the sludge storage chamber to pass through the flow holes and be distributed on both sides of the surge suppressor.

[0029] With this configuration, when dirt impacts the retaining component, the dirt can be separated into multiple streams by the flow holes. Each stream can generate frictional resistance with the hole wall when passing through the flow holes, which reduces the kinetic energy of the dirt flow and lowers the flow velocity, thereby weakening the overall impact force of the surge.

[0030] Furthermore, when dirt flows through the flow hole to the space between the baffle and the surge suppressor, the dirt can flow around the two sides of the surge suppressor under the obstruction of the surge suppressor, which can further dissipate the energy of the surge and thus further suppress the surge of dirt.

[0031] In some embodiments, the end of the surge suppressor that faces away from the abutment extends towards the tank cover, forming a gap with the bottom wall of the tank cover. This allows contaminants to re-converge at the gap between the surge suppressor and the bottom wall of the tank cover after flowing through the overflow orifice and circulating along both sides of the surge suppressor. The collision of the two streams of contaminants further dissipates the remaining kinetic energy of the contaminants, thereby further dissipating the surge energy and enhancing the surge suppression capability of the wastewater tank. When the wastewater tank is used in cleaning equipment, it further avoids the risk of damage to the suction device of the cleaning equipment from liquid ingress.

[0032] In some embodiments, the first water-blocking member is provided with a rotation limiting structure, which is used to limit the rotation range of the blocking member. The blocking member abuts against the rotation limiting structure to reach the blocking position or the open position. In this way, the blocking member can maintain a fixed angle when it is in the blocking position or the open position, thereby avoiding the instability of the blocking member's surge suppression effect due to the randomness of the blocking member's rotation, and ensuring the consistency of the surge suppression effect of the sewage tank under different operating conditions.

[0033] In some embodiments, when the sewage tank is in an upright position and the tank cover module is detached from the tank body, the stop member also has a tilting position. When the stop member is in the open position, it can rotate towards the bottom wall of the tank body to the tilting position under the action of gravity, so that the dirt on the stop member falls into the sewage storage chamber.

[0034] With this design, when the user pulls the tank cover module upwards to clean the wastewater tank, as the cover module moves away from the tank body, the stop component rises along with it and gradually separates from the inlet pipe. At this point, the stop component can rotate downwards from the open position under gravity. As the cover module is pulled upwards further, and the stop component is completely separated from the inlet pipe, it loses the support of the inlet pipe and will rotate further towards the inner bottom wall of the tank under gravity until it is perpendicular or nearly perpendicular to the inner bottom wall, reaching the tilting position. During the rotation of the stop component, solid impurities originally attached to its surface can fall off due to gravity or rotational inertia and fall into the bottom of the wastewater storage chamber, thus achieving automated cleaning of the stop component and allowing the user to centrally process the waste.

[0035] Secondly, embodiments of this application provide a cleaning device, comprising:

[0036] Floor brush assembly, used to clean the surface to be cleaned;

[0037] The body assembly has one end rotatably connected to the floor brush assembly, and the other end of the body assembly is equipped with a handle.

[0038] As in any of the preceding embodiments, the wastewater tank is mounted on the body assembly and rotates with the body assembly to switch between a lying position and an upright position.

[0039] The cleaning device provided in this application embodiment has the aforementioned wastewater tank, and therefore has the beneficial effects of the aforementioned wastewater tank. It can effectively suppress the surge when the cleaning device is used flat, reduce the risk of damage to the suction device by liquid ingress, and simplify the structure of the wastewater tank. It also collects the dirt in the wastewater tank on the side of the bottom wall of the storage chamber facing the baffle, so that when the user cleans the wastewater tank, the dirt can be poured out together, reducing the time for the user to clean the wastewater tank and improving cleaning efficiency and user experience.

[0040] Thirdly, embodiments of this application provide a cleaning system, including:

[0041] Base station; the base station has a charging function.

[0042] As in any of the preceding embodiments, the cleaning device is connected to a base station for charging.

[0043] The cleaning system provided in this application embodiment has the above-mentioned cleaning equipment, and therefore has the beneficial effects of the above-mentioned cleaning equipment. It can effectively suppress the surge when the cleaning equipment is used flat, reduce the risk of damage to the suction device by liquid ingress, and simplify the structure of the sewage tank. It also gathers the dirt in the sewage tank to the side of the baffle facing the sewage storage chamber on the inner bottom wall, so that when the user cleans the sewage tank, the dirt can be poured out together, reducing the time for the user to clean the sewage tank and improving cleaning efficiency and user experience.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0067] This application provides a cleaning device. The cleaning device may include a robotic vacuum cleaner, a floor scrubber, or other equipment capable of cleaning surfaces. For example, the surface to be cleaned may be a floor. The following description primarily uses the scenario of the cleaning device cleaning a floor as an example to illustrate the structure of the cleaning device.

[0068] Figure 1 This is a schematic diagram of the structure of a cleaning device 100 provided in an embodiment of this application.

[0069] Please refer to Figure 1 Specifically, the cleaning device 100 includes a body assembly 3 and a floor brush assembly 2. The floor brush assembly 2 is located at the bottom of the body assembly 3 to clean the surface to be cleaned. A handle 4 is provided at the end of the body assembly 3 away from the surface to be cleaned so that the user can hold it and push the cleaning device 100 to clean the surface.

[0070] The floor brush assembly 2 includes a mounting base and a roller brush. The mounting base is rotatably mounted on the bottom of the body assembly 3, and the roller brush is located on the side of the mounting base facing the surface to be cleaned. When the roller brush rotates relative to the mounting base, the roller can contact the surface to be cleaned, thereby cleaning the surface.

[0071] The cleaning device 100 also includes a clean water tank, which is mounted on the body assembly 3 and positioned away from the floor brush assembly 2. The clean water tank supplies clean water to the floor brush assembly 2 or the surface to be cleaned, allowing the floor brush assembly 2 to better clean the surface. This process also generates wastewater. The floor brush assembly 2 also absorbs impurities from the surface during cleaning. These impurities may include paper scraps, food crumbs, hair, etc.

[0072] The cleaning equipment 100 also includes a water pump that can pump clean water from the clean water tank to the floor brush assembly 2. The installation position of the water pump in the cleaning equipment 100 can be determined according to the existing structure of the cleaning equipment 100, and will not be described in detail here.

[0073] The cleaning device 100 may include a walking mechanism. The floor brush assembly 2 is mounted on the walking mechanism. When the cleaning device 100 is in operation, the user can push the handle 4 of the cleaning device 100, which, driven by the walking mechanism, causes the cleaning device 100 to move in different directions, thereby cleaning the surface to be cleaned by the floor brush assembly 2.

[0074] Please refer to Figure 1 The cleaning device 100 may include a wastewater tank 1. The wastewater tank 1 is also installed on the side of the floor brush assembly 2 away from the surface to be cleaned. The wastewater tank 1 has a suction port and a wastewater storage chamber. The suction port is located at the top of the wastewater tank 1 and communicates with the wastewater storage chamber. The suction port is used to extract gas from the wastewater storage chamber to create a negative pressure environment in the wastewater storage chamber, so that dirt generated during the cleaning process by the cleaning device 100 can be sucked into the wastewater storage chamber for centralized storage under the pressure difference. This allows the user to centrally empty the dirt in the wastewater tank 1 after the cleaning device 100 has completed its cleaning operation. The top of the wastewater tank 1 refers to the end of the wastewater tank 1 away from the floor brush assembly 2. Correspondingly, the bottom of the wastewater tank 1 refers to the end of the wastewater tank 1 closest to the floor brush assembly 2.

[0075] It should be noted that the dirt in the cleaning process can include the wastewater, impurities, and mixtures of dirt generated during the cleaning process mentioned above.

[0076] The cleaning equipment 100 may include a suction device. For example, the suction device may be a suction pump. The suction device is located on the side of the wastewater tank 1 where the suction port is provided, and is fixed relative to the wastewater tank 1. That is, the positions of the suction device and the wastewater tank 1 do not change relative to each other on the cleaning equipment 100. The suction device is configured to suction from the suction port, removing gas from the wastewater storage chamber to create a negative pressure environment in the wastewater storage chamber, so that dirt generated during the cleaning process of the cleaning equipment 100 can be sucked into the wastewater storage chamber for centralized storage under the action of pressure difference.

[0077] To meet the cleaning needs of low-ceilinged spaces (such as under beds and sofas), the cleaning device 100 is equipped with a flat-lying function. For example, when the cleaning device 100 is used in a flat-lying position, its body component 3 can be positioned nearly parallel to the surface to be cleaned, allowing for scenarios where the cleaning device 100 can be pushed and pulled back and forth on the surface. It should be noted that these scenarios can include both pushing the cleaning device 100 forward and pushing it backward.

[0078] To meet the needs of the cleaning equipment 100 when it is used in a flat position, the wastewater tank, clean water tank, suction device, etc. of the cleaning equipment can rotate relative to the floor brush assembly 2, so that the cleaning equipment 100 can switch between a flat position and an upright position.

[0079] Please refer to Figure 1When the cleaning equipment 100 is in an upright position, the part of the cleaning equipment 100 excluding the walking mechanism and the cleaning module (such as the sewage tank 1) stands on the surface to be cleaned. At this time, the sewage tank 1 is also in an upright position, with the suction port of the sewage tank 1 away from the surface to be cleaned, and the suction device located above the suction port.

[0080] The wastewater tank 1 can rotate relative to the brush assembly 2 so that when the cleaning equipment 100 switches between a lying position and an upright position, the wastewater tank 1 can also switch between a lying position and an upright position simultaneously.

[0081] In related technologies, because the cleaning equipment, excluding the walking mechanism and floor brush components (such as the wastewater tank), can be used in a nearly parallel, horizontal position to the surface to be cleaned, both the wastewater tank and the suction device are mounted on the machine body, placing them close to the surface. When the cleaning equipment is in this horizontal position, the user will push it back and forth on the surface. The wastewater in the tank contains a large amount of wastewater, causing it to shake violently due to the movement of the cleaning equipment, creating a "surge." This surge causes significant fluctuations in the liquid level within the wastewater tank, even splashing droplets. Since the suction port of the wastewater tank is connected to the suction device, the splashed droplets are more likely to rush through the suction port to the suction device, significantly increasing the risk of damage to the suction device due to liquid ingress.

[0082] Therefore, how to suppress the surge generated in the sewage tank when the cleaning equipment is used horizontally and reduce the risk of damage to the suction device has become a technical problem to be solved.

[0083] In view of this, this application embodiment also provides a wastewater tank for cleaning equipment. Through the arrangement of a stopper in the wastewater tank 1, the stopper has a stop position and an open position when rotating relative to the inlet pipe. The stopper is configured to rotate under the drive of dirt in the storage chamber. Thus, when the wastewater tank 1 is applied to the cleaning equipment 100, and the cleaning equipment 100 is pushed back and forth by the user in a flat state, the dirt in the wastewater tank 1 is strongly pulled and pushed back during user use, causing the dirt in the storage chamber to move back and forth under the action of inertia and pushing / pulling forces. This drives the stopper to rotate back and forth, thereby preventing some dirt from moving towards the suction port. While suppressing surges, the stopper also blocks some dirt on the side of the stopper facing the inner bottom wall of the storage chamber, reducing the risk of dirt entering the suction device through the suction port, thereby reducing the risk of damage to the suction device from liquid ingress.

[0084] When dirt from the wastewater tank 1 flows into the area between the retaining member and the tank cover module, as the cleaning device is moved back and forth by the user in its lying position, this dirt may also move towards the inner bottom wall of the wastewater storage chamber under the influence of inertia, causing a surge that drives the retaining member to switch from the retaining position to the open position. At this time, as the gap between the retaining member and the first side wall gradually increases, this dirt will again be collected on the inner bottom wall of the retaining member facing the wastewater storage chamber. This makes it convenient for the user to empty the dirt along with the wastewater when cleaning the wastewater tank, reducing the time spent cleaning the wastewater tank and improving cleaning efficiency and user experience.

[0085] The wastewater tank of the cleaning equipment provided in the embodiments of this application will be further described below with reference to the accompanying drawings.

[0086] Figure 2 This is a schematic diagram of the sewage tank 1 provided in the embodiments of this application in an upright state. Figure 3 for Figure 2 A schematic diagram of the structure of the wastewater tank 1 in its lying-flat state. Figure 6 for Figure 3 A cross-sectional view of the wastewater tank 1 in the AA direction. Figure 7 for Figure 6 A schematic diagram of the structure of the wastewater tank 1 from another perspective.

[0087] Please refer to Figure 2 , Figure 3 and Figure 7 The wastewater tank 1 includes a cover module 20 and a tank body 10. The cover module 20 is installed on the top of the tank body 10 and is assembled with the tank body 10 to form a wastewater storage chamber 30. The cover module 20 has a suction port 22. The wastewater storage chamber 30 is in communication with the suction port 22. The suction port 22 is used to remove gas from the wastewater storage chamber 30 to create a negative pressure environment in the wastewater storage chamber 30.

[0088] Please refer to Figure 1 and Figure 7 The housing 10 has a dirt inlet pipe 11, which can suck the dirt collected and generated by the cleaning equipment 100 during the cleaning process into the dirt storage chamber 30 under the action of pressure difference, so that the dirt generated by the cleaning equipment 100 during the cleaning process can be stored in the dirt storage chamber 30 for the user to perform unified cleaning later.

[0089] Please refer to Figure 1 , Figure 6 and Figure 7Specifically, the cleaning equipment 100 has a suction device that can draw air from the suction port 22, thereby drawing the gas in the sewage storage chamber 30 out of the sewage tank 1 through the suction port 22 and into the suction device, so that a pressure difference is formed inside and outside the sewage storage chamber 30 in the sewage tank 1, and a negative pressure environment is formed inside the sewage storage chamber 30. In this way, under the action of the pressure difference, the sewage inlet pipe 11 can draw the dirt generated during the cleaning process of the cleaning equipment 100 into the sewage storage chamber 30 through the outlet end 111 of the sewage inlet pipe 11.

[0090] Figure 4 for Figure 2 Schematic diagram of the structure of the wastewater tank 1 and the removal tank 10 Figure 1 , Figure 5 for Figure 2 Schematic diagram of the structure of the wastewater tank 1 and the removal tank 10 Figure 2 .

[0091] Please refer to Figure 4 , Figure 5 and Figure 6 The cover module 20 is provided with a stopper 40 to prevent some of the dirt in the sludge storage chamber 30 from moving toward the suction port 22. Specifically, the stopper 40 has a stopper position A and an open position B when rotating relative to the sludge inlet pipe 11. During the process of the stopper 40 rotating from the open position B to the stopper position A, the gap between the stopper 40 and the first side wall 12 gradually decreases, and the distance between the free end of the stopper 40 and the sludge storage chamber 30 on the inner bottom wall gradually increases.

[0092] Please refer to Figure 1 , Figure 2 and Figure 6 The inner bottom wall of the sludge storage chamber 30 mentioned above is the side of the sludge storage chamber 30 that is close to the surface 200 to be cleaned when the cleaning equipment 100 is in normal use.

[0093] Please refer to Figure 1 and Figure 2 It should be noted that the normal use of the cleaning equipment 100 mentioned above refers to the non-lying-flat usage state of the cleaning equipment 100. For example, during normal use, the cleaning equipment 100 can be used upright or tilted (a usage state between upright and lying flat). Correspondingly, the wastewater tank 1 can be in an upright state, or the wastewater tank 1 can be in a tilted state between an upright state and a lying flat state.

[0094] Please refer to Figure 2 , Figure 6 and Figure 7In this embodiment, the tank body 10 has a first side wall 12 in the circumferential direction. When the sewage tank 1 is in an upright state, the tank body 10 and the cover module 20 of the sewage tank 1 are arranged in sequence along the direction perpendicular to the surface to be cleaned 200. At this time, the first side wall 12 is perpendicular to the surface to be cleaned 200. The dirt generated by the cleaning device 100 during the cleaning process enters the sewage inlet pipe 11 under the action of pressure difference and then enters the sewage storage chamber 30 for storage.

[0095] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As the cleaning equipment 100 continues to be used, the amount of dirt stored in the dirt storage chamber 30 gradually increases. Since there is a large height difference between the outlet end 111 of the dirt inlet pipe 11 and the suction device in the direction perpendicular to the surface to be cleaned 200, when the user pushes the cleaning equipment 100 to use it, the dirt stored in the dirt storage chamber 30 will not rush to the end of the sewage tank 1 with the suction port 22 under the action of inertia, so that the dirt in the sewage tank 1 has no risk of entering the suction device.

[0096] Please refer to Figure 2 and Figure 6 When the cleaning device 100 is used lying flat, the wastewater tank 1 is also in a lying position. At this time, the first side wall 12 is close to the surface to be cleaned 200, and the dirt in the wastewater tank 1 will accumulate at the first side wall 12 under the action of gravity. If the user repeatedly pushes the cleaning device 100 to clean the surface to be cleaned 200 at this time, the dirt in the wastewater tank 1 will be pulled and pushed back during the user's use, moving back and forth towards or away from the tank cover module 20, causing a surge. When the surge height is high, some dirt may surge towards the gap between the wastewater inlet pipe 11 and the tank cover module 20 in the direction away from the surface to be cleaned 200, and move towards one side of the suction port 22, resulting in a greater risk of liquid inlet damage to the suction device.

[0097] Figure 8 for Figure 3 Another cross-sectional view of the wastewater tank in the AA direction.

[0098] Please refer to Figure 4 , Figure 6 and Figure 8When the wastewater tank 1 of this embodiment is used lying flat, the tank cover module 20 is provided with a stop member 40. Therefore, under the action of gravity or the inertia of the dirt flowing in the direction of the tank cover module 20, the stop member 40 can switch from the open position B to the stop position A. In this way, the stop member 40 can block some dirt, suppress the surge of dirt, and also block some dirt on the side of the stop member 40 facing the inner bottom wall of the dirt storage chamber 30, so as to reduce the risk of dirt entering the suction port. Thus, when the wastewater tank 1 is used in the cleaning equipment 100, the risk of dirt entering the suction device through the suction port is reduced, thereby reducing the risk of damage to the suction device.

[0099] Please refer to Figure 4 , Figure 6 and Figure 8 When the blocking member 40 switches from the open position B to the blocking position A, the gap between the blocking member 40 and the first side wall 12 gradually decreases, and the distance between the free end of the blocking member 40 and the inner bottom wall of the sludge storage cavity 30 gradually increases. This allows the blocking member 40 to get closer to the first side wall 12 in the sludge storage cavity 30 and rotate toward the side closer to the lid module 20. In this way, when the blocking member 40 is in the blocking position A, it can better prevent some of the dirt in the sludge storage cavity 30 from moving toward the suction port.

[0100] Please refer to Figure 4 , Figure 6 and Figure 8 Meanwhile, since there is a certain gap between the abutment 40 and the first side wall 12, some dirt will surge into the area between the abutment 40 and the lid module 20 when a surge occurs. As the cleaning device 100 is moved back and forth by the user in its lying position, this dirt may also move towards the inner bottom wall of the dirt storage chamber 30 under the action of inertia and cause a surge, driving the abutment 40 to switch from the abutment position A to the open position B. At this time, since the gap between the abutment 40 and the first side wall 12 gradually increases, this dirt can also be gathered again on the inner bottom wall of the abutment 40 towards the dirt storage chamber 30 through the gap between the abutment 40 and the first side wall 12, thus concentrating the dirt on the inner bottom wall of the dirt storage chamber 30.

[0101] Furthermore, when the user repeatedly moves the cleaning device 100, the dirt can move back and forth within the dirt storage chamber 30, causing the stop member 40 to cycle between the open position B and the stop position A. During this time, the dirt can repeatedly flush the inner wall of the dirt storage chamber 30, thereby collecting the dirt adhering to the inner wall of the dirt storage chamber 30 onto the side of the stop member 40 facing the bottom wall of the dirt storage chamber 30, reducing the probability of dirt adhering to the lid module 20. This allows the user to empty the dirty water tank along with the dirt, reducing the time spent cleaning the tank and improving cleaning efficiency and user experience.

[0102] Please refer to Figure 1 , Figure 6 and Figure 7 It should be noted that when the cleaning equipment 100 is used at an angle, the sewage tank 1 is also in an angled state. When the angle of inclination of the cleaning equipment 100 is small, that is, when the angle of inclination of the cleaning equipment 100 is small compared to when it is used upright, there is still a large height difference between the outlet end 111 of the sewage inlet pipe 11 in the sewage tank 1 and the suction device. When the user pushes the cleaning equipment 100 to move, the dirt stored in the sewage storage chamber 30 will not rush to the end of the sewage tank 1 with the suction port 22 under the action of inertia, so that there is no risk of dirt in the sewage tank 1 entering the suction device.

[0103] Please refer to Figure 2 , Figure 5 and Figure 6 When the cleaning device 100 is tilted at a large angle, that is, when the cleaning device 100 is tilted at a large angle relative to its upright use, the height difference between the outlet end 111 of the sewage inlet pipe 11 in the sewage tank 1 and the suction device decreases. At this time, some dirt may flow away from the surface to be cleaned 200 into the gap between the sewage inlet pipe 11 and the tank cover module 20. When the user pushes the cleaning device 100 forward, the blocking member 40 can also switch between the blocking position A and the open position B under the action of the dirt in the sewage tank 1, blocking the dirt, suppressing the surge of dirt, and preventing the dirt in the sewage tank 1 from flowing into the area between the sewage inlet pipe 11 and the tank cover module 20.

[0104] It is understood that the wastewater tank 1 provided in this embodiment, through the setting of the abutment 40, allows the abutment 40 to cycle between the abutment position A and the open position B under the drive of the dirt in the wastewater storage chamber 30 when the cleaning device 100 is used lying flat. This achieves the effect of surge suppression, reduces the risk of damage to the suction device by liquid ingress, simplifies the structure of the wastewater tank 1, and gathers the dirt in the wastewater tank 1 on the side of the abutment 40 facing the inner bottom wall of the wastewater storage chamber 30, so that when the user cleans the wastewater tank 1, the dirt can be emptied together, reducing the time for the user to clean the wastewater tank 1, improving cleaning efficiency and user experience.

[0105] Please refer to Figures 4 to 6 In some embodiments, the stop 40 rotates to abut against the circumferential outer wall of the inlet pipe 11 to reach the open position B.

[0106] Specifically, the stop member 40 rotates due to the movement of dirt, thus switching between the stop position A and the open position B. When the stop member 40 is in the open position B, it abuts against the circumferential outer wall of the inlet pipe 11. This allows the inlet pipe 11 to mechanically limit the maximum rotation angle of the stop member 40, ensuring that a dimensionally stable return channel is formed between the stop member 40 and the first side wall 12 when the stop member 40 is in the open position B.

[0107] Meanwhile, by making the stop member 40 abut against the sewage inlet pipe 11, the maximum rotation angle of the stop member 40 can be limited, preventing the stop member 40 from rotating excessively under the impact of dirt, so that it cannot switch to the open position under the drive of dirt, thus ensuring the stability of the position switching of the stop member 40 under different working conditions.

[0108] Figure 10 for Figure 2 Schematic diagram of the structure of the middle water-blocking component 23 and the abutment component 40 Figure 1 .

[0109] Please refer to Figure 4 , Figure 7 and Figure 10 In some embodiments, the abutment 40 has a clearance notch 41 on the side facing the sewage inlet pipe 11. In the open position B, at least part of the clearance notch 41 abuts against the circumferential outer wall of the sewage inlet pipe 11. This ensures that when the abutment position A is in the open position B, it can fit tightly against the circumferential outer wall of the sewage inlet pipe 11, ensuring the limiting effect of the sewage inlet pipe 11 on the abutment 40, limiting the maximum opening of the abutment 40 after the sewage tank is assembled, ensuring the stability of the limiting effect of the sewage inlet pipe 11 on the abutment 40, and allowing the dirt flowing into the area between the abutment 40 and the tank cover module 20 to flow back smoothly and accumulate on the side of the abutment 40 facing the sewage storage chamber 30 on the inner bottom wall.

[0110] Please refer to Figure 4 and Figure 10 In addition, by setting the clearance gap 41, it is possible to prevent the blocking member 40 from interfering with the sewage inlet pipe 11 when it rotates, ensuring that the blocking member 40 rotates smoothly under the drive of dirt, so that the blocking member 40 can effectively suppress the surge.

[0111] Specifically, the outline shape of the clearance notch 41 is matched with the outline shape of the outer wall of the inlet pipe 11. When the stop member 40 is rotated to the open position B, the clearance notch 41 can achieve a large-area stable fit with the outer wall of the inlet pipe 11, thereby improving the stability of the stop member 40 when it is in the open position B.

[0112] Please refer to Figure 4 and Figure 10For example, when the sewage inlet pipe 11 is a circular cross-section pipe, the clearance notch 41 can be set as an arc-shaped notch. The radius of curvature of the arc-shaped notch is adapted to the outer diameter of the sewage inlet pipe 11 to ensure that the contact area between the arc-shaped notch and the circumferential outer wall of the sewage inlet pipe 11 is maximized when the blocking member 40 is in the open position B.

[0113] It should be noted that the example of a circular cross-section pipe described above is merely an example of a specific implementation and is not intended to limit the scope of protection of this application. In practical applications, the cross-sectional shape of the inlet pipe 11 can be designed according to specific needs, such as elliptical, polygonal, or other irregular shapes. Correspondingly, the shape of the clearance notch 41 on the stop member 40 can also be adapted to the specific shape of the inlet pipe 11, as long as it can effectively abut against the outer wall of the inlet pipe 11 and form a suitable return channel when in the open position B. Any clearance notch 41 structure that matches the shape of the inlet pipe 11 falls within the scope of protection of this application.

[0114] Please refer to Figure 4 , Figure 6 and Figure 10 In some embodiments, when the sewage tank 1 is in an upright position, the blocking member 40 rotates from the blocking position A to the open position B under the action of gravity.

[0115] Specifically, when the sewage tank 1 is in an upright position, the abutment 40 can rotate under its own weight, increasing the gap between the free end of the abutment 40 and the first side wall 12, thus reaching the open position B. In the open position B, the increased gap connects the sewage storage cavity 30 and the surrounding area of ​​the sewage inlet pipe 11, allowing solid dirt near the tank cover module 20 to pass smoothly and preventing solid dirt from adhering to the tank cover module 20. At the same time, the distance between the free end of the abutment 40 and the sewage storage cavity 30 on the inner bottom wall gradually decreases, so as to connect the sewage storage cavity 30 and the surrounding area of ​​the sewage inlet pipe 11, reducing the air resistance of the sewage tank 1.

[0116] In addition, the open position B allows the blocking member 40 to be in a natural relaxed state, avoiding the structural member from maintaining a stressed posture for a long time when not in operation.

[0117] Please refer to Figure 4 , Figure 6 and Figure 7 In some embodiments, the shape of the free end matches the shape enclosed by the inner wall of the first sidewall 12, and when the stop member 40 is rotated to the stop position A, the distance between the free end and the inner wall of the first sidewall 12 is 2-4 mm.

[0118] Specifically, during the cleaning process, the cleaning device 100 may suck in hair, fibers, or other solid impurities. When the distance between the free end of the stop member 40 and the inner wall of the first side wall 12 is less than 2mm, such as 1mm, 1.5mm, or 1.8mm, the solid dirt mentioned above can easily get stuck in the gap between the free end and the first side wall 12, causing the stop member 40 to be obstructed from rotating and unable to switch normally between the stop position A and the open position B.

[0119] Please refer to Figure 4 , Figure 6 and Figure 7 When the distance between the free end of the stop member 40 and the inner wall of the first side wall 12 is greater than 4mm, such as 5mm, 6mm or 7mm, the excessive gap will reduce the cooperation in the flow of dirt and greatly weaken the ability to suppress surges. Therefore, when the cleaning device 100 generates a surge during the pushing process, dirt may pass through the gap between the free end and the first side wall 12 at high speed, causing the dirt to easily enter the gap between the inlet pipe 11 and the cover module 20 under the action of inertia, and move towards the side of the suction port 22, resulting in a large risk of liquid ingress damage to the suction device.

[0120] Please refer to Figure 4 , Figure 6 and Figure 7 By balancing the two scenarios described above, and through multiple inference calculations and statistical analysis of solid contaminant composition, as well as simulation and physical experiments, the optimal range of this distance was obtained. Specifically, the distance between the free end and the inner wall of the first sidewall 12 is 2-4 mm, for example, 2 mm, 3 mm, or 4 mm. This effectively suppresses contaminant surges while preventing contaminant blockage of the gap and ensuring the flexibility of the rotating stop 40, thus guaranteeing the reliability of the wastewater tank 1. Therefore, when the wastewater tank 1 is used in the cleaning equipment 100, the risk of damage to the inlet liquid of the cleaning equipment 100's suction device can be reduced.

[0121] Please refer to Figure 2 , 4 , Figure 6 , Figure 7 and Figure 10 In some embodiments, the box cover module 20 includes a box cover 21 and a water-blocking component 23. The suction port 22 is disposed on the box cover 21. The water-blocking component 23 is connected to the bottom end of the box cover 21 and is blocked in the sewage storage chamber 30 at the outlet end 111 of the sewage inlet pipe 11 to prevent the dirt output from the sewage inlet pipe 11 from moving toward the suction port 22. The abutment 40 is rotatably connected to the water-blocking component 23.

[0122] Specifically, the cover module 20 includes a cover 21, which is installed on the top of the body 10. A sealing structure can be provided between the cover 21 and the inner wall of the body 10 to ensure the sealing of the wastewater tank 1 at the connection between the cover 21 and the body 10. For example, the sealing structure can be a sealing ring. The top of the body 10 can be understood as the side of the wastewater tank 1 away from the surface 200 to be cleaned when the wastewater tank 1 is applied to the cleaning equipment 100 and the cleaning equipment 100 is in an upright position. The bottom of the wastewater tank 1 can be understood as the side of the wastewater tank 1 closer to the surface 200 to be cleaned.

[0123] Please refer to Figure 4 and Figure 7 The lid module 20 also includes a water-blocking component 23, which is connected to the bottom of the lid 21. When the lid 21 is placed on the body 10, the water-blocking component 23 is located inside the body 10. This can prevent the dirt output from the inlet pipe 11 from moving toward the suction port 22 when the cleaning equipment 100 is in use (lying flat or normal use), thus avoiding damage to the suction device.

[0124] Please refer to Figure 1 , Figure 6 and Figure 7 When the sewage inlet pipe 11 draws the dirt from the cleaning process of the cleaning equipment 100 into the sewage tank 1 through the outlet end 111 of the sewage inlet pipe 11 under the action of pressure difference, the dirt can directly enter the sewage storage chamber 30 under the blocking and guidance of the water blocking component 23, so that it will not enter the suction device through the suction port 22.

[0125] Please refer to Figure 4 and Figure 6 In this embodiment, the blocking member 40 is rotatably connected to the water-blocking assembly 23. When the dirt in the sewage tank 1 surges, the dirt can be blocked by the blocking member 40 first. Some dirt can enter between the blocking member 40 and the water-blocking assembly 23 through the gap between the blocking member 40 and the first side wall 12. Thus, the water-blocking assembly 23 can block this part of the dirt a second time, which can further enhance the effect of the sewage tank 1 in suppressing the surge. When the sewage tank 1 is applied to the cleaning equipment 100, it can further reduce the risk of liquid damage to the suction device in the cleaning equipment 100.

[0126] Please refer to Figure 4 In some embodiments, the water-blocking assembly 23 includes a first water-blocking member 231, which is disposed on the top of the sewage inlet pipe 11 and surrounds the sewage inlet pipe 11 on the side adjacent to the first sidewall 12 in the circumferential direction. The abutment member 40 is rotatably connected to the first water-blocking member 231.

[0127] Please refer to Figure 6 and Figure 7Specifically, the first water-blocking component 231 is located above the outlet end 111 of the sewage inlet pipe 11, forming a direct blockage to the suction port 22. When the sewage tank 1 is in operation, the dirt output from the sewage inlet pipe 11 is blocked by the first water-blocking component 231, which can prevent the dirt from splashing upwards to the area near the suction port 22.

[0128] Meanwhile, the first water-blocking component 231 is arranged around the side of the sewage inlet pipe 11 adjacent to the first side wall 12 in the circumferential direction. This forms an isolation structure between the first side wall 12 and the suction port 22. When the cleaning equipment 100 is used lying flat, the dirt entering the sewage storage chamber 30 can be restricted to the area between the first water-blocking component 231 and the first side wall 12. At this time, even if some dirt passes over the blocking component 40 under strong surge, it will be blocked by the first water-blocking component 231 and cannot enter the space where the suction port 22 is located, further reducing the risk of dirt in the sewage tank 1 entering the suction device.

[0129] Please refer to Figure 4 In some embodiments, the water-blocking assembly 23 further includes a surge suppressor 232, which is connected to the side of the first water-blocking member 231 adjacent to the first sidewall 12. When the abutment member 40 rotates, it abuts against the surge suppressor 232 to reach the abutment position A.

[0130] Specifically, when a strong surge occurs, if some contaminants pass over the baffle 40, the surge suppressor 232 can block the passing contaminants again, further weakening the surge energy and reducing the risk of contaminants continuing to flow towards the suction port 22. Furthermore, in the event of an abnormal situation where the baffle 40 fails to switch to the baffle position A, the surge suppressor 232 can still function as an independent structure, continuing to perform its surge suppression function and improving the fault tolerance of the wastewater tank 1.

[0131] Please refer to Figure 4 When the stop member 40 rotates to the stop position A, the stop member 40 abuts against the surge suppression member 232, thereby limiting the rotation of the stop member 40 and preventing the stop member 40 from rotating excessively under the impact of dirt, so that it cannot switch to the open position B under the drive of dirt, thus ensuring the stability of the operation of the stop member 40.

[0132] It is understood that in this embodiment, the outline shape of the surge suppressor 232 matches the shape of the area enclosed by the first water-blocking member 231 and the first sidewall 12, so that the surge suppressor 232 can make full use of the entire cross section of the area to block, maximize the effective blocking area, and ensure the suppression effect on the surge.

[0133] In some embodiments, the projection of the surge suppressor 232 onto the abutment 40 is located in the central region of the abutment 40. The abutment 40 has a sheet-like structure and has a plurality of flow holes 42. Dirt in the dirt storage cavity 30 can pass through the flow holes 42 to be distributed on both sides of the surge suppressor 232.

[0134] Please refer to Figure 4 and Figure 5 Specifically, the abutment 40 is provided with multiple flow holes 42, which form multiple flow channels. When dirt impacts the abutment 40, the dirt can be separated by the flow holes 42 to form multiple flow streams. Each flow stream can generate frictional resistance with the hole wall of the flow hole 42 when it passes through the flow hole 42, which reduces the flow kinetic energy of the dirt and reduces the flow velocity, thereby weakening the overall impact force of the surge.

[0135] In this embodiment, no restrictions are placed on the number, size, or arrangement of the flow holes 42. Adaptive selections can be made according to actual needs.

[0136] Please refer to Figure 4 In this embodiment, the projection of the surge suppressor 232 on the stopper 40 is located in the middle region of the stopper 40. When dirt flows through the flow hole 42 to the space between the stopper 40 and the surge suppressor 232, the dirt can flow around the two sides of the surge suppressor 232 along the two side edges of the surge suppressor 232, thereby further dissipating the energy of the surge and further suppressing the surge of dirt.

[0137] Please refer to Figures 3 to 5 In some embodiments, the end of the surge suppressor 232 facing away from the abutment 40 extends towards the tank cover 21, forming a gap with the bottom wall of the tank cover 21. This allows the contaminants, after being diverted and flowing around both sides of the surge suppressor 232, to re-converge at the gap between the surge suppressor 232 and the bottom wall of the tank cover 21. The collision of the two contaminants upon merging further dissipates the remaining kinetic energy of the contaminants, thereby further dissipating the surge energy and enhancing the surge suppression capability of the sewage tank 1, further avoiding the risk of damage to the suction device.

[0138] It should be noted that this embodiment does not impose any restrictions on the specific value of the distance between the surge suppression component 232 and the bottom wall of the cover 21, and can be adapted to meet actual needs.

[0139] Figure 11 for Figure 2 Schematic diagram of the structure of the middle water-blocking component 23 and the abutment component 40 Figure 2 .

[0140] Please refer to Figure 4 , Figure 10 and Figure 11 In some embodiments, the first water-blocking member 231 is provided with a rotation limiting structure 2311, which is used to limit the rotation range of the blocking member 40. The blocking member 40 abuts against the rotation limiting structure 2311 to reach the blocking position A or the open position B.

[0141] Please refer to Figure 4 , Figure 10 and Figure 11 Specifically, the blocking member 40 is provided with a clearance portion 43, which is used to avoid interference between the blocking member 40 and the first water-blocking member 231 when rotating. The clearance portion 43 has a first surface 431 and a second surface 432 connected together. When the blocking member 40 rotates to the blocking position A, the first surface 431 of the clearance portion 43 abuts against the top area of ​​the rotation limiting structure 2311 to limit the blocking member 40 from continuing to rotate. When the blocking member 40 rotates to the open position B, the second surface 432 of the clearance portion 43 abuts against the bottom area of ​​the rotation limiting structure 2311 to limit the blocking member 40 from continuing to rotate. This ensures that the blocking member 40 maintains a preset tilt angle in the blocking position A and the open position B to ensure the surge blocking effect.

[0142] Figure 9 for Figure 3 Another cross-sectional view of the wastewater tank in the AA direction.

[0143] Please refer to Figure 3 and Figure 9 In some embodiments, when the sewage tank 1 is in an upright position and the tank cover module 20 is detached from the tank body 10, the blocking member 40 also has a tilting position C. When the blocking member 40 is in the open position B, it can rotate towards the bottom wall of the tank body 10 under the action of gravity to the tilting position C, so that the dirt on the blocking member 40 falls into the sewage storage chamber 30.

[0144] Please refer to Figure 3 , Figure 4 and Figure 9Specifically, during the operation of the sewage tank 1, dirt carrying solid impurities may be trapped and deposited on the surface of the retainer 40 when passing through the flow hole 42 on the retainer 40. When the user needs to clean the sewage tank 1 and pulls the tank cover module 20 upwards, the sewage tank 1 remains upright. In the initial stage of removal, as the tank cover module 20 moves away from the tank body 10, the retainer 40 rises with the tank cover module 20 and gradually separates from the sewage inlet pipe 11. At this time, the retainer 40 can rotate downwards from the open position B under the action of gravity. When the tank cover module 20 is pulled upwards again, after the retainer 40 is completely separated from the sewage inlet pipe 11, the retainer 40 loses the support of the sewage inlet pipe 11 and will rotate further towards the inner bottom wall of the tank body 10 under the action of gravity until it is perpendicular or nearly perpendicular to the inner bottom wall of the tank body 10, reaching the tilting position C. During the rotation of the stop part 40, solid impurities that were originally attached to the surface of the stop part 40 can fall off due to gravity or rotational inertia and fall into the bottom of the dirt storage chamber 30, thereby realizing the automatic cleaning of the stop part 40 so that users can centrally process the dirt.

[0145] Please refer to Figure 1 , Figure 2 and Figure 4 This application also provides a cleaning device 100, including a floor brush assembly 2, a body assembly 3, and a wastewater tank 1 as described in any of the above embodiments.

[0146] The sewage tank 1 has been described in the above embodiments and will not be repeated here.

[0147] Please refer to Figure 1 and Figure 2 One end of the body assembly 3 is rotatably connected to the floor brush assembly 2, and the other end of the body assembly 3 is provided with a handle 4. The floor brush assembly 2 is used to clean the surface 200 to be cleaned. The user can hold the handle 4 to push the cleaning device 100 to move, thereby cleaning the surface 200 to be cleaned.

[0148] The cleaning system provided in this embodiment has the aforementioned wastewater tank 1, and therefore has the beneficial effects of the aforementioned wastewater tank 1. When the cleaning device 100 is used in a flat position, the blocking member 40 can be driven by the dirt in the wastewater storage chamber 30 to cyclically switch between the blocking position A and the open position B. While achieving the effect of surge suppression and reducing the risk of damage to the suction device by liquid ingress, it can also simplify the structure of the wastewater tank 1 and collect the dirt in the wastewater tank 1 on the side of the blocking member 40 facing the inner bottom wall of the wastewater storage chamber 30, so that when the user cleans the wastewater tank 1, the dirt can be poured out together, reducing the time for the user to clean the wastewater tank 1 and improving cleaning efficiency and user experience.

[0149] Please refer to Figure 1Thirdly, embodiments of this application provide a cleaning system, including a base station and a cleaning device 100 as described in any of the above embodiments.
