Technical Field

[0001] This disclosure relates to the field of smart home technology, and more specifically, to a liquid storage component, cleaning device, and cleaning system. Background Technology

[0002] With the development of modern society, in order to save time and maintain household hygiene, more and more people are buying cleaning equipment to clean their homes promptly and conveniently. Cleaning equipment can automatically clean floors throughout the room.

However, there is a problem that wastewater cannot be discharged smoothly from the drain outlet of the container.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this disclosure is to provide a liquid storage component, cleaning device, and cleaning system that can improve the reliability of liquid drainage through the drain port.

The blocking component has a blocked state and an open state. In the blocked state, the blocking component blocks the drain port. In the open state, the blocking component opens the drain port, and the first projection of the drain component at least partially coincides with the drain port.

[0014] In one exemplary embodiment of this disclosure, the sealing member includes a sealing cap and an annular sealing portion surrounding the sealing cap, and the annular sealing portion is connected to the sealing cap to form a groove with an opening facing the drain port; when the sealing member blocks the drain port, the annular sealing portion seals against the box body and surrounds the drain port.

[0015] In one exemplary embodiment of this disclosure, one end of the drainage member is connected to the sealing cap.

[0016] In one exemplary embodiment of this disclosure, one end of the drainage member is connected to the central region of the sealing cap.

[0017] In one exemplary embodiment of this disclosure, the size and shape of the opening are the same as the size and shape of the drain outlet.

[0018] In one exemplary embodiment of this disclosure, the switch assembly includes a plurality of the drain elements, which are arranged in the width direction of the drain port.

[0019] In one exemplary embodiment of this disclosure, the drainage element is made of an elastic material.

[0020] In an exemplary embodiment of this disclosure, the switch assembly further includes a rotating member and an elastic member. The rotating member is rotatably disposed on the liquid storage assembly, and the sealing member and the drainage member are located on the rotating member. Under the elastic force of the elastic member, the rotating member can drive the sealing member to be in the sealing state. Under the action of an external force, the rotating member can overcome the elastic force of the elastic member and rotate relative to the housing to drive the sealing member to be in the open state.

[0021] In one exemplary embodiment of this disclosure, the sealing member is detachably connected to the rotating member.

[0022] In one exemplary embodiment of this disclosure, the rotating member includes a first end and a second end, and the rotating member is rotatably connected to the liquid storage assembly through an intermediate portion between the first end and the second end; the elastic member is located between the first end of the rotating member and the housing, and the sealing member and the drainage member are located on the second end of the rotating member.

[0023] In one exemplary embodiment of this disclosure, the liquid storage assembly further includes:

[0024] A side cover plate is connected to the housing, and the switch assembly is located between the side cover plate and the housing; the side cover plate is provided with a through hole, and the first end of the rotating member protrudes from the through hole.

[0025] In one exemplary embodiment of this disclosure, the box body includes a top plate and a bottom plate disposed opposite to each other, and a side plate located between the top plate and the bottom plate, wherein the drain outlet is disposed on the side plate or the bottom plate.

[0026] According to another aspect of this disclosure, a cleaning apparatus is provided, the cleaning apparatus comprising:

[0027] Equipment body;

[0028] The liquid storage component described above is detachably connected to the device body.

[0029] In one exemplary embodiment of this disclosure, the cleaning device further includes a mopping component and a squeegee, the squeegee being configured to direct wastewater on the mopping component to the liquid storage assembly.

[0030] In one exemplary embodiment of this disclosure, the mopping component is a roller mop or a tracked mop.

[0031] In one exemplary embodiment of this disclosure, the cleaning device is a self-propelled cleaning device.

[0032] According to another aspect of this disclosure, a cleaning system is provided, the cleaning system comprising:

[0033] The aforementioned cleaning equipment;

[0036] In one exemplary embodiment of this disclosure, the triggering component includes a driver and a trigger element. The driver responds to a drainage signal to drive the trigger element to move, and the movement of the trigger element causes the blockage to switch from the blocked state to the open state.

[0037] The liquid storage assembly disclosed herein has a guide member positioned axially opposite to the drain outlet. When the guide member moves outward from the drain outlet, it guides the flow of wastewater, allowing it to overcome surface tension and flow more easily out of the drain outlet. This reduces turbulent flow at the drain outlet, provides a smoother channel for gas entry, and achieves efficient separation and exchange between gas and liquid. This significantly accelerates the rate of internal and external pressure balance, thus solving the problem of slow water discharge caused by slow gas-water exchange and significantly improving sewage discharge efficiency. Furthermore, without the guide member, wastewater discharged directly from the drain outlet is prone to splashing due to the lack of guidance and gas exchange, flowing down the sidewalls of the container and soiling them. The guide member confines the wastewater along its extended flow path, causing it to flow out of the drain outlet along or near the surface of the guide member, thus mitigating the problem of wastewater soiling the sidewalls of the container.

[0038] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0060] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0061] Embodiments of this disclosure provide a cleaning system, such as Figure 1 and Figure 2 As shown, the cleaning system includes a cleaning device 10 and a base station 20. The cleaning device 10 can be, for example, a mopping robot, a sweeping robot, or a combined sweeping and mopping robot; the cleaning device 10 may include a device body 30, a drive module, a sensing module, a control module, a cleaning module, an energy module, and a human-machine interaction module. The base station 20 is used to dock with the cleaning device 10, allowing it to be parked. The cleaning device 10 can perform functions such as charging, self-cleaning, docking, sewage discharge, water replenishment, and dust collection on the base station 20.

[0062] In some embodiments, the device body 30 is configured to automatically move along a target direction on a travel surface, which can be the surface to be cleaned by the cleaning device 10. If the cleaning device 10 is a sweeping and mopping robot, then the cleaning device 10 operates on the ground.

[0063] In some embodiments, the drive module may include a drive wheel assembly. The drive module can control both the left and right wheels simultaneously. For more precise control of the machine's movement, the drive module preferably includes a left drive wheel assembly and a right drive wheel assembly. The left and right drive wheel assemblies are symmetrically arranged along a transverse axis defined by the device body 30. In some embodiments, to enable the cleaning device 10 to move more stably or with greater mobility on the ground, the cleaning device 10 may include one or more steering wheels. The steering wheels may be driven wheels or drive wheels, and their structural forms include, but are not limited to, casters. The steering wheels may be located in front of the drive wheel assembly, and a drive motor provides power to the drive wheel assembly and / or the steering wheels.

[0064] In some embodiments, the cleaning device 10 may be a self-propelled cleaning device. The sensing module may include a position determination device located above the device body 30, a buffer located on the forward portion of the device body 30, and a cliff sensor and ultrasonic sensor, infrared sensor, magnetometer, accelerometer, gyroscope, odometer, and other sensing devices located at the bottom of the device body 30, providing the control module with various position and motion state information of the device body 30. For example, the forward portion of the device body 30 is provided with a buffer. During the cleaning process, when the drive wheel assembly propels the cleaning device 10 to walk on the ground, the buffer detects one or more objects in the travel path of the cleaning device 10 via a sensor module, such as a collision sensor. The cleaning device 10 can pass through the objects detected by the collision sensor, such as steps, obstacles, or walls, and the control drive structure makes the cleaning device 10 respond to the objects, such as stepping over steps.

[0065] In some embodiments, the control module can combine distance and speed information fed back from sensors such as buffers, cliff sensors, ultrasonic sensors, infrared sensors, magnetometers, accelerometers, gyroscopes, and odometers to comprehensively determine the current working state of the robot vacuum cleaner, such as climbing stairs, crossing thresholds, walking on carpets, being on a cliff, stuck above or below, having a full dustbin, or being picked up. It will also provide specific next action strategies for different situations, making the cleaning device 10 work more in line with the user's requirements and providing a better user experience. Furthermore, the control module can plan the most efficient and reasonable cleaning path and cleaning method based on real-time map information drawn using SLAM (Simultaneous Localization and Mapping), which can improve the cleaning efficiency of the cleaning device 10.

[0066] In some embodiments, the energy module may include a rechargeable battery, such as a nickel-metal hydride battery or a lithium battery. The rechargeable battery may be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit. These circuits are then connected to a microcontroller control circuit. The main unit is charged by connecting to a charging station via charging electrodes located on the side or bottom of the device.

[0067] In some embodiments, the human-machine interface module may include buttons on the main control panel for users to select functions; it may also include a display screen and / or indicator lights and / or a speaker, which display the current status of the machine or the available function options to the user; and it may also include a mobile client application. For path navigation cleaning equipment, the mobile client can display a map of the environment where the equipment is located, as well as the machine's position, providing users with richer and more user-friendly functions.

[0068] In some embodiments, the cleaning module may include a dry cleaning module, or a dry and wet cleaning module. The dry cleaning module may include a roller brush assembly, side brushes, etc. Figure 3 As shown, the wet cleaning module may include a mopping component 50, a water tank, etc. The mopping component 50 in the wet cleaning module may be a roller mop or a tracked mop for mopping and washing the surface to be cleaned.

[0069] The roller mop can be mounted on the equipment body 30 via a mounting bracket, and can clean the area to be cleaned along the travel path of the equipment body 30 under the drive of the equipment body 30. During cleaning, the roller mop is driven by a drive motor to rotate relative to the mounting bracket, and in the process of rotation, it rolls and rubs the surface to be cleaned, thereby efficiently removing dirt. To improve the cleaning efficiency of the roller mop during the rolling and rubbing process, cleaning fluid can be sprayed onto the roller mop, so that the roller mop is wetted by the cleaning fluid before rolling and rubbing the surface to be cleaned, thereby further improving the cleaning efficiency. Similarly, the tracked mop can also be mounted on the equipment body via a mounting bracket, and can be wetted by spraying cleaning fluid before rolling and rubbing the surface to be cleaned.

[0070] like Figures 3-6As shown, when the cleaning equipment 10 includes a wet cleaning module, the equipment body 30 is typically equipped with a removable liquid storage component 40 to recover wastewater generated during the cleaning operation of the wet cleaning module. Specifically, the mopping component 50 sprays cleaning fluid to clean the surface to be cleaned, leaving wastewater on the area of ​​the mopping component 50 after cleaning. Before the next cleaning of the surface, this wastewater needs to be scraped off, and the cleaning fluid can be re-sprayed to improve the cleaning effect. The liquid storage component 40 is equipped with a box 41 and a water collection component 44. The cleaning device 10 is also equipped with a squeegee. The squeegee can scrape the sewage on the mopping component 50 into the water collection tank 441 of the water collection component 44. The negative pressure device is connected through the negative pressure hole 415 of the box 41 so that the sewage in the water collection tank 441 is sucked into the box 41 by the negative pressure, thereby realizing the recycling of the sewage scraped off by the squeegee from the mopping component 50.

[0071] like Figures 4-6 As shown, the box body 41 includes a box body 411 and a cover plate 412. The cover plate 412 covers the box body 411 to form a liquid storage cavity 413. The drain port 414 of the box body 41 can be located at the bottom or side wall of the box body 41, and drains water by gravity. The liquid storage assembly 40 is also provided with a switch assembly 42, which can be used to block and open the drain port 414. The switch assembly 42 includes a blocking member 422, which has a blocking state and an open state. In the blocking state, the blocking member 422 blocks the drain port 414; in the open state, the blocking member 422 opens the drain port 414.

[0072] In some embodiments, the switch assembly 42 may include a rotating member 421, an elastic member, and a sealing member 422. The rotating member 421 is rotatably disposed on the liquid storage assembly 40, and the sealing member 422 is located on the rotating member 421. Under the elastic force of the elastic member, the rotating member 421 can drive the sealing member 422 to block the drain port 414. Under the action of an external force, the rotating member 421 can overcome the elastic force of the elastic member and rotate relative to the housing 41, thereby driving the sealing member 422 to open the drain port 414. That is, the switch assembly 42 can keep the sealing member 422 under the pile body that blocks the drain port 414 through the elastic member, and the drain port 414 can be opened by pushing the rotating member 421 to rotate through an external force, so as to discharge sewage.

[0073] When the cleaning device 10 needs to discharge wastewater, it can automatically locate the base station 20. After docking with the base station 20, the rotating part 421 on the cleaning device 10 can be pushed by the corresponding trigger component on the base station 20 to open the drain port 414 for wastewater discharge. The wastewater discharged from the box 41 can be recycled by the base station 20, thus achieving automatic wastewater discharge. Furthermore, after docking with the base station 20, when the cleaning device 10 needs charging, the charging terminal on the cleaning device 10 contacts the charging terminal on the base station 20, enabling the base station 20 to charge the self-propelled cleaning device 10. When the cleaning device 10 needs to be replenished with clean water and / or cleaning fluid, it can connect its water inlet to the water supply nozzle on the base station 20 for automatic water supply. Therefore, after docking with the base station 20, the cleaning device 10 can achieve automatic water supply and drainage, automatic charging, and other functions without manual operation by the user, improving the user experience.

[0074] The triggering component includes a driver and a trigger element. The driver responds to a drain signal to drive the trigger element to move, which in turn drives the rotating element 421 to rotate. The rotating element 421 then drives the sealing element 422 to switch from a sealed state to an open state, opening the drain port 414 for drainage. After drainage is complete, the driver retracts the trigger element, and the rotating element 421 returns to its initial position under the action of the elastic element, thereby causing the sealing element 422 to re-seal the drain port 414. Because the driver responds to a drain signal to drive the trigger element, the rotating element 421 is only driven to rotate via the triggering component when drainage is required. After drainage is complete, the triggering component releases the external force applied to the rotating element 421, thereby releasing the external force indirectly applied to the elastic element. This ensures that the elastic force provided by the elastic element remains within an effective range, thus guaranteeing the sealing performance of the sealing element 422 on the drain port 414 and preventing leakage due to decreased sealing performance. It should be noted that the drain signal can be sent by the base station 20 or by the cleaning equipment 10. For example, when the cleaning equipment 10 determines that the liquid level in the box 41 has reached the preset height, after the cleaning equipment 10 is connected to the base station 20, the driver can send a drain signal to the trigger component to control the switch component 42 to open the drain port 414 for sewage discharge.

[0075] The driver can be a drive motor, and a gear can be installed on the output shaft of the drive motor. The trigger can be fixed on a rack, and the gear meshes with the rack. The drive motor drives the gear to rotate, which in turn drives the rack to reciprocate along the length of the rack, thereby driving the trigger to reciprocate, thus pushing the rotating component 421. In some embodiments, the trigger component may include a protrusion structure formed on the base station 20. When the cleaning device 10 docks with the base station 20, the protrusion structure can directly push the rotating component 421 to rotate, so that the sealing component 422 is in the open state; when the cleaning device 10 is separated from the base station 20, the sealing component 422 returns to the sealed state.

[0076] In some embodiments, the switch assembly may be an electric valve assembly, and the sealing member 422 may be in a sealed or open state under electric drive, that is, the cleaning device 10 may open the switch assembly to open or seal the drain port 414 on its own without cooperating with the base station 20.

[0077] Currently, when the drain port 414 is opened to drain wastewater using gravity, the wastewater cannot drain smoothly due to the closed cavity of the robot vacuum's housing 41, the pressure inside and outside the housing 41 being balanced, the drain port 414 being typically small due to structural limitations, and the surface tension of the wastewater. This significantly impacts the user experience. Furthermore, when wastewater flows out under gravity, external air enters the liquid storage chamber 413 of the housing 41 from the drain port 414 to balance the internal and external pressures. Therefore, the drain port 414 needs to simultaneously accommodate air intake and water output. The slow exchange rate of air and water results in slow water output, and wastewater flows out along the side walls of the housing 41, soiling the side walls and further affecting the user experience.

[0078] To address the aforementioned technical problems, embodiments of this disclosure provide a liquid storage assembly, such as... Figures 7-11 As shown, the liquid storage assembly 40 includes a housing 41 and a switch assembly 42. The housing 41 forms a liquid storage cavity 413 and a drain port 414 communicating with the liquid storage cavity 413. The switch assembly 42 includes a sealing member 422 and a drain member 423. The drain member 423 is located on the side of the sealing member 422 facing the housing 41. The sealing member 422 has a sealing state and an open state. In the sealing state, the sealing member 422 seals the drain port 414. In the open state, the sealing member 422 opens the drain port 414, and the projection of the drain member 423 is at least partially coincident with the drain port 414. The projection is the projection of the drain member 423 on the drain port 414 along the axial direction X of the drain port 414. That is, the drain member 423 is positioned corresponding to the drain port 414 on the axial direction X of the drain port 414. When the projection of the drainage element 423 and the drain port 414 are completely coincident, that is, the drainage element 423 is positioned directly opposite the drain port 414 in the axial direction X of the drain port 414, the drainage element 423 can have a gap around the drain port 414 in the circumferential direction.

[0079] The liquid storage component 40 provided in this disclosure has a guide member 423 positioned on the axial direction X of the drain port 414 corresponding to the position of the drain port 414. When the guide member 423 moves toward the outside of the drain port 414, it can guide the flow of sewage, allowing the sewage to overcome tension and flow out of the drain port 414 more easily. This reduces the turbulent flow of sewage at the drain port 414, provides a smoother channel for gas entry, and achieves efficient separation and exchange of gas and liquid. This greatly accelerates the speed of internal and external pressure balance, thereby solving the problem of slow water discharge caused by slow gas and water exchange speed and significantly improving sewage discharge efficiency. Meanwhile, if there is no draining element 423, the sewage will be discharged directly from the drain port 414. The sewage is prone to splashing due to the lack of guidance and gas exchange inside and outside the drain port 414. It will flow out along the side wall of the box 41 and dirty the side wall. However, the draining element 423 can constrain the sewage on the flow path extended by the draining element 423, so that the sewage flows out of the drain port 414 along the surface or near the draining element 423, which improves the problem of sewage dirtying the side wall of the box 41.

[0080] In some embodiments, when the sealing member 422 is in a sealed state, at least a portion of the diverting member 423 is located in the drain port 414. Since at least a portion of the diverting member 423 is located in the drain port 414 when the sealing member 422 is in a sealed state, the diverting member 423, when moving towards the outside of the drain port 414, can better guide the flow of sewage, allowing the sewage to overcome tension and flow out of the drain port 414 more easily, reducing turbulent flow of sewage at the drain port 414. This allows external gas to enter the storage chamber 413 along the gap between the diverting member 423 and the inner wall of the drain port 414, achieving efficient separation and exchange of gas and liquid, greatly accelerating the speed of internal and external pressure balance, thereby solving the problem of slow water discharge caused by slow gas and water exchange, and significantly improving sewage discharge efficiency. It is understandable that when the sealing member 422 is in the sealing state, the drainage member 423 can also be located outside the drain port 414 in the axial direction X, that is, the end of the drainage member 423 has a small gap between the axial direction X and the drain port 414.

[0081] In some embodiments, when the sealing member 422 is in the open state, at least a portion of the drain member 423 is located in the drain port 414. Because at least a portion of the drain member 423 is located in the drain port 414, the drain member 423 can better guide the flow of sewage, allowing sewage to overcome tension and flow more easily from the drain port 414, reducing turbulent flow of sewage at the drain port 414. This allows external gas to enter the storage chamber 413 along the gap between the drain member 423 and the inner wall of the drain port 414, achieving efficient separation and exchange of gas and liquid, greatly accelerating the speed of internal and external pressure balance, thereby solving the problem of slow water discharge caused by slow gas and water exchange, and significantly improving sewage discharge efficiency. It is understood that when the sealing member 422 is in the open state, the drain member 423 can also be located outside the drain port 414 in the axial direction X, that is, the end of the drain member 423 has a small gap between the axial direction X and the drain port 414.

[0082] In some embodiments, the switch assembly 42 includes a rotating member 421, an elastic member, a sealing member 422, and a draining member 423. The rotating member 421 is rotatably disposed on the liquid storage assembly 40, and the sealing member 422 and the draining member 423 are located on the rotating member 421. Under the elastic force of the elastic member, the rotating member 421 can drive the sealing member 422 to block the drain port 414, and at least a portion of the draining member 423 is located in the drain port 414. When the housing 41 needs to be drained, the rotating member 421 can overcome the elastic force of the elastic member and rotate relative to the housing 41 under the action of external force, so as to drive the sealing member 422 to open the drain port 414. Hereinafter, this disclosure uses the switch assembly 42 including the rotating member 421, the elastic member, the sealing member 422, and the draining member 423 as an example to describe the liquid storage assembly 40 in detail.

[0083] In some embodiments, when the rotating member 421 drives the sealing member 422 to open the drain port 414, at least a portion of the guiding member 423 is located in the drain port 414. In the initial stage of sewage discharge, the sewage volume is large, and the guiding member 423 can quickly guide the sewage to flow out in a concentrated manner. As the sewage discharge process progresses, the sewage volume gradually decreases, but the guiding member 423 remains in the drain port 414, continuing to constrain the flow direction of the sewage, avoiding drainage failure due to changes in sewage volume, and ensuring the stability and continuity of the sewage discharge process. Simultaneously, since a portion of the guiding member 423 is always located within the drain port 414 when it is open, the gap formed between the guiding member 423 and the inner wall of the drain port 414 remains stable. This stable gap provides a continuous and unobstructed channel for external gas to enter the storage chamber 413, ensuring that the internal and external pressures can be quickly and continuously balanced, further increasing the water discharge rate and avoiding intermittent discharge during the sewage discharge process. In other examples, when the rotating member 421 drives the sealing member 422 to open the drain port 414, the end of the guiding member 423 may also be located outside the drain port 414. When the guiding member 423 moves towards the outside of the drain port 414 under the drive of the rotating member 421, it can guide the flow of sewage, making it easier for sewage to flow out of the drain port 414.

[0084] In some embodiments, such as Figures 12-15 As shown, one end of the drainage component 423 is connected to the sealing component 422, and the other end faces the drain port 414. This connection forms a continuous drainage channel extending from the inside of the storage chamber 413 to the drain port 414. When sewage flows from the storage chamber 413 to the drain port 414, it can flow smoothly along the surface of the drainage component 423, improving the sewage discharge speed. Simultaneously, connecting the drainage component 423 to the sealing component 422 ensures that the entire drainage component 423 is located on the side of the sealing component 422 facing the drain port 414, preventing the drainage component 423 from affecting the sealing performance of the sealing component 422 to the drain port 414 and guaranteeing the sealing performance of the sealing component 422 to the drain port 414. Furthermore, this connection method makes full use of the space near the sealing component 422, making the layout of the drainage component 423 more compact. The drain element 423 extends from the sealing element 422 to the drain port 414 without the need for additional support structures, simplifying the overall structure of the switch assembly 42, reducing the number of parts, and lowering production and assembly costs. In other examples, one end of the drain element 423 may also be directly connected to the rotating element 421, as long as the sealing element 422 seals the drain port 414; this disclosure does not impose any limitations on this.

[0085] When the drain component 423 is connected to the sealing component 422, the sealing component 422 and the drain component 423 are integrally molded. During the sewage discharge process, the sewage will exert a certain impact force on the drain component 423 and the sealing component 422. The integral structure can better withstand this impact force, avoiding problems such as the drain component 423 falling off or the sealing component 422 being damaged due to loose connection, thus extending the service life of the components. At the same time, the integral molding structure ensures a seamless connection between the sealing component 422 and the drain component 423. Combined with the sealing effect of the sealing component 422 on the drain port 414, a more reliable sealing effect can be achieved, effectively preventing sewage leakage and improving the safety and reliability of the liquid storage component 40. In addition, the integral molding process (such as injection molding) can process the sealing component 422 and the drain component 423 in one go, reducing the number of parts and assembly steps, and reducing errors and costs in the production process.

[0086] The sealing component 422 can be made of rubber, which gives it certain deformation properties, thereby improving its sealing performance over the drain port 414.

[0087] The drainage component 423 is made of an elastic material. Elastic materials have good cushioning properties, absorbing the impact of sewage during discharge. When the drainage component 423 comes into contact with the inner wall of the drain port 414 or other components, its elastic deformation reduces the impact force, protects the structural integrity of the relevant components, and extends their service life. Simultaneously, elastic materials typically have good corrosion resistance and aging resistance. For example, using rubber, it can operate stably for a long time in the humid environment inside the housing 41, and is not easily corroded by chemicals in sewage or lose its elasticity due to aging, thus ensuring the service life of the drainage component 423.

[0088] The drainage component 423 can be made of the same material as the sealing component 422, which means it can be formed by a one-time molding process.

[0089] In some embodiments, such as Figures 12-15As shown, the sealing member 422 includes a sealing cap 4221 and an annular sealing portion 4222 surrounding the sealing cap 4221. The annular sealing portion 4222 is connected to the sealing cap 4221 to form a groove 4223 with an opening facing the drain port 414. When the sealing member 422 seals the drain port 414, the annular sealing portion 4222 seals against the box body 41 and surrounds the drain port 414. The annular sealing portion 4222 seals against the box body 41 around the drain port 414, forming an annular sealing surface, which enhances the sealing effect of the sealing member 422 on the drain port 414. The design of the groove 4223 provides a certain elastic deformation space for the annular sealing portion 4222. When the sealing member 422 seals the drain port 414, the annular sealing portion 4222 can deform into the groove 4223 after being squeezed, further improving the tightness and reliability of the seal. Meanwhile, when the sealing component 422 seals the drain port 414, due to the formation of the groove 4223, sewage exists outside the drain port 414 when the drain port 414 is sealed, that is, the sewage outside the drain port 414 is connected with the sewage inside the box 41; when the sealing component 422 opens the drain port 414, the sewage in the groove 4223 can be discharged directly, thereby driving the sewage in the box 41 to be discharged, reducing the resistance in the initial stage of sewage discharge, and making the sewage discharge process smoother.

[0090] Among them. For example, Figure 15 As shown, one end of the draining component 423 is connected to the sealing cap 4221. The connection between the draining component 423 and the sealing cap 4221 makes the draining component 423 part of the sealing component 422, and the two can move synchronously with the rotating component 421. When the sealing component 422 blocks the drain port 414, the draining component 423 is located in the liquid storage chamber 413; when the sealing component 422 opens the drain port 414, the draining component 423 can accurately enter the drain port 414 and play a draining role, ensuring that the draining component 423 is in place in a timely manner during the sewage discharge process, avoiding the draining delay or failure caused by the asynchronous movement of the draining component 423 and the sealing component 422, and improving the overall working efficiency of the switch assembly 42.

[0091] Among them, such as Figure 14 and Figure 15As shown, one end of the drainage component 423 is connected to the central area of ​​the sealing cover 4221. The central area of ​​the sealing cover 4221 is the central location where sewage converges. Connecting the drainage component 423 here allows sewage to be guided evenly from the center outwards. The centrally connected drainage component 423 extends from the center of the sealing cover 4221 towards the drain port 414, forming a drainage channel running through the center. This concentrates the sewage in the central area of ​​the sealing cover 4221 and guides it to the drain port 414, minimizing contact between the sewage and the edge of the sealing cover 4221 and the side wall of the box 41. Even if a small amount of sewage spreads during the flow, it will be blocked by the structure around the central drainage component 423, preventing the sewage from soiling the side wall and keeping the box 41 clean. In addition, it ensures that the drainage component 423 is aligned with the center of the drain port 414, guaranteeing the reliability of the drainage effect.

[0092] The size and shape of the opening in groove 4223 are the same as those in drain port 414. Because the opening in groove 4223 is the same size and shape as the drain port 414, when the sealing member 422 opens drain port 414, the opening in groove 4223 and drain port 414 can quickly align, forming a smooth transition channel, which facilitates the rapid flow of sewage from storage chamber 413 into drain port 414. Since the opening and drain port 414 are the same size and shape, they do not cause additional obstruction to the flow of sewage, reducing initial resistance during sewage discharge, increasing the discharge speed, and making the discharge process smoother. Of course, the size and shape of the opening in groove 4223 can also be different from those in drain port 414, as long as a seal is achieved; this disclosure does not impose any restrictions on this.

[0093] In some embodiments, such as Figure 13 As shown, the sealing element 422 is detachably connected to the rotating element 421. As the component directly in contact with the drain port 414, the sealing element 422 is prone to failure due to wear, aging, or contamination during long-term use. The detachable connection allows users or maintenance personnel to easily remove the sealing element 422 from the rotating element 421 for replacement or cleaning, without needing to replace the entire rotating element 421 or the switch assembly 42, greatly simplifying the maintenance process and saving maintenance time and costs. For example, when the sealing performance of the sealing element 422 deteriorates, simply replacing it with a new one will restore the sealing effect of the drain port 414; the operation is simple and easy. Simultaneously, the individual replacement of the sealing element 422 avoids the situation where the entire rotating element 421 is scrapped due to damage to the sealing element 422, reducing equipment maintenance and replacement costs. Furthermore, during the production process, the sealing element 422 and the rotating element 421 can be manufactured using different materials and processes. The most suitable material can be selected according to their respective functional requirements, further reducing costs while ensuring performance.

[0094] The sealing component 422 and the rotating component 421 can be connected by means of snap-fit, thread, adhesive or other connection structures to achieve a detachable connection, so as to ensure a reliable connection between the sealing component 422 and the rotating component 421.

[0095] In some embodiments, when the sealing member 422 seals the drain port 414, the guide member 423 is located at the middle position of the drain port 414 in the depth direction of the storage cavity 413. The middle position of the guide member 423 in the drain port 414 creates vertical gaps between the guide member 423 and the inner wall of the drain port 414 in the depth direction of the storage cavity 413. These gaps provide a uniform and unobstructed channel for external gas to enter the storage cavity 413, allowing gas to enter from the top and accelerating the speed of internal and external pressure balance. Simultaneously, the middle position of the guide member 423 concentrates the sewage flow out at the middle position, minimizing the contact opportunity between the sewage and the side wall of the housing 41. It is understood that the guide member 423 may also be located near the top or bottom of the drain port 414 in the depth direction of the storage cavity 413; this disclosure does not limit this.

[0096] In some embodiments, such as Figure 14 As shown, the width of the guide member 423 in the width direction of the drain port 414 is greater than its thickness in the height direction of the drain port 414. The larger width of the guide member 423 allows it to contact more sewage, increasing the drainage area and thus more effectively guiding the sewage towards the drain port 414. The larger width also confines more sewage to its surface or vicinity, reducing sewage diffusion in the width direction and allowing the sewage to flow out of the drain port 414 more concentratedly, increasing the outflow rate per unit time and further solving the problem of slow outflow. Simultaneously, the smaller thickness of the guide member 423 in the height direction results in a larger gap between the guide member 423 and the inner wall of the drain port 414. These larger gaps provide a wider channel for external gas to enter the storage chamber 413, facilitating rapid gas entry and accelerating the rate of internal and external pressure balance. At the same time, the smaller thickness reduces the obstruction of gas flow by the guide member 423, making gas flow smoother and preventing sewage discharge interruptions or slowdowns due to insufficient gas entry.

[0097] In some embodiments, such as Figure 16As shown, the switch assembly 42 includes multiple guide elements 423 arranged along the width of the drain port 414. The arrangement of multiple guide elements 423 increases the total drainage area, enabling more sewage to flow into the drain port 414 simultaneously. Their arrangement along the width of the drain port 414 covers a wider area, effectively guiding sewage from different widths and preventing sewage accumulation in the width direction due to insufficient drainage area of ​​a single guide element 423. This increases the outflow rate per unit time and further solves the problem of slow outflow. Regarding gas flow, multiple gaps are formed between the multiple guide elements 423, providing more channels for external gas to enter the storage chamber 413. The more uniform distribution of these gaps accelerates the gas entry speed, allowing the internal and external pressures to reach equilibrium more quickly, ensuring a continuous and smooth outflow of sewage. Simultaneously, the multiple gaps reduce the risk of gas flow being affected by blockage of a single gap by sewage or impurities, improving the reliability of gas flow.

[0098] In some embodiments, such as Figure 12 As shown, the rotating component 421 includes a first end 4211 and a second end 4212. The rotating component 421 is rotatably connected to the liquid storage assembly 40 through the intermediate portion between the first end 4211 and the second end 4212. An elastic component is located between the first end 4211 of the rotating component 421 and the housing 41, and a sealing component 422 and a drainage component 423 are located on the second end 4212 of the rotating component 421. The rotating component 421 forms a lever structure with the intermediate portion as the fulcrum. The elastic component is located at the first end 4211, and the sealing component 422 and the drainage component 423 are located at the second end 4212. When an external force is applied to the first end 4211, according to the lever principle, the force of the elastic component can be overcome with a small force, causing the sealing component 422 at the second end 4212 to open the drain port 414. In terms of structural layout, the elastic element, sealing element 422, and drainage element 423 are respectively arranged at both ends of the rotating element 421, making full use of the length space of the rotating element 421 and making the structural layout of the switch assembly 42 more reasonable and compact. The elastic element is located at the first end 4211, away from the liquid storage chamber 413 and the drain port 414, reducing the corrosion and pollution of the elastic element by sewage and extending its service life. The sealing element 422 and drainage element 423 are located at the second end 4212, close to the drain port 414, which facilitates the quick opening or closing of the drain port 414 during rotation, improving the response speed of the switch assembly 42. The restoring force provided by the elastic element at the first end 4211 and the sealing force of the sealing element 422 on the drain port 414 at the second end 4212 can be balanced through the rotation fulcrum, so that the sealing element 422 can stably seal the drain port 414 in the non-sewage state, and will not be accidentally opened due to slight vibration or external interference, thus improving the safety of the liquid storage assembly 40.

[0099] Among them, such as Figures 6-8As shown, the liquid storage assembly 40 also includes a side cover plate 43, which is connected to the housing 41. A switch assembly 42 is located between the side cover plate 43 and the housing 41. The side cover plate 43 has a through hole 431 through which the first end 4211 of the rotating component 421 protrudes. The space formed by the side cover plate 43 and the housing 41 provides effective protection for the switch assembly 42. The switch assembly 42 is located inside the side cover plate 43, preventing direct collision with external objects and reducing damage to components caused by collisions. Simultaneously, the side cover plate 43 prevents dust and impurities from entering the switch assembly 42, ensuring the cleanliness and normal operation of components such as the rotating component 421 and the elastic component, thus extending the service life of the switch assembly 42. The side cover plate 43 conceals the switch assembly 42 between itself and the housing 41, exposing only the operating end of the rotating component 421, making the appearance of the liquid storage assembly 40 neater and more aesthetically pleasing. This avoids the exposed components of the switch assembly 42 affecting the overall aesthetics, improves the visual quality of the product, and provides a better visual experience for the user.

[0100] The side cover plate 43 is detachably connected to the box body 41, and the rotating part 421 is rotatably connected to the side cover plate 43 and the box body 41, that is, the rotating shaft of the rotating part 421 can be rotatably set on the side cover plate 43 and the box body 41 respectively.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
