DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0049] Implementation method one:

[0050] 1 to 5 , a sewage tank 100 according to some embodiments of the present application is shown below.

[0051] As shown in Figures 1 to 5, according to some embodiments of the present application, a sewage tank 100 includes a tank body 10, a sealing member 20, and a driving mechanism 30. The tank body 10 forms an opening 11 and a receiving cavity 12. The sealing member 20 is disposed in the receiving cavity 12. The driving mechanism 30 is connected to the sealing member 20 and is used to drive the sealing member 20 to move to open or close the opening 11.

[0052] In the sewage tank 100 of the embodiment of the present application, when the driving mechanism 30 drives the sealing member 20 to open the opening 11, sewage can flow out of the tank body 10. When the driving mechanism 30 drives the sealing member 20 to close the opening 11, sewage can be stored in the tank body 10. The user no longer needs to manually empty the sewage; the driving mechanism 30 can be used to discharge the sewage, resulting in a simple structure and easy operation.

[0053] Specifically, the housing 10 is used to form a storage cavity 12 for storing sewage within the sewage tank 100. The shape of the housing 10 includes, but is not limited to, circular or square. The housing 10 may be formed using one or more of rotational molding, blow molding, injection molding, and sheet metal welding processes. The opening 11 may be circular in shape and connect the storage cavity 12 with the external environment of the housing 10, allowing sewage in the storage cavity 12 to be discharged through the opening 11.

[0054] The seal 20 can be made of rubber, and the contact surface between the seal 20 and the housing 10 can be stepped or arc-shaped. The size of the seal 20 can be greater than or equal to the size of the opening 11, so that the seal 20 can cover the opening 11 and prevent sewage from flowing out of the gap between the seal 20 and the housing 10 and contaminating the external environment.

[0055] The driving mechanism 30 can be driven by a motor 31, pneumatically driven, hydraulically driven, etc. There are various ways to connect the driving mechanism 30 to the box body 10. The driving mechanism 30 can be connected to the box body 10 with the help of an adapter. For example, the driving mechanism 30 is installed on the adapter and then installed on the box body 10 through the adapter. The driving mechanism 30 can also be directly connected to the box body 10, such as by a fixed connection method such as welding and riveting, or a detachable connection method such as a snap connection and a threaded connection.

[0056] Please refer to Figure 5. In some embodiments, the driving mechanism 30 includes a motor 31, a transmission mechanism 32 and a connecting shaft 33. The connecting shaft 33 connects the transmission mechanism 32 and the seal 20. The motor 31 drives the seal 20 to reciprocate through the transmission mechanism 32 and the connecting shaft 33.

[0057] In this way, the driving mechanism 30 drives the sealing member 20 to reciprocate, so that the sealing member 20 can open or close the opening 11, thereby realizing the collection and discharge of sewage.

[0058] Specifically, the motor 31 can be a stepper motor 31. By adjusting the operating time of the motor 31, the distance that the seal 20 moves can be set, thereby achieving automatic opening and closing of the opening 11. The output shaft of the motor 31 is connected to the transmission mechanism 32. The motor 31 can rotate forward or reverse, thereby driving the transmission mechanism 32 to rotate forward or reverse, further driving the connecting shaft 33 and the seal 20 to reciprocate, thereby opening and closing the opening 11.

[0059] Please refer to FIG. 5 . In some embodiments, the connecting shaft 33 includes a shaft body 34 and a connecting portion 35 connected to one end of the shaft body 34 . The connecting portion 35 is connected to the sealing member 20 .

[0060] In this way, the shaft body 34 and the sealing member 20 can be connected via the connecting portion 35 .

[0061] Specifically, one end of the shaft 34 is connected to the transmission mechanism 32, and the other end is fixed to the connecting portion 35. The transmission mechanism 32 drives the shaft 34 and the connecting portion 35 to move, thereby driving the seal 20 connected to the connecting portion 35 to move, thereby opening or closing the opening 11. The cross-section of the shaft 34 can be circular or rectangular. The shaft 34 and the connecting portion 35 can be fixedly connected by welding or other methods, or can be integrally formed. The side of the connecting portion 35 facing away from the seal 20 can be concave to guide sewage along the surface of the connecting portion 35 toward the opening 11. By adjusting the degree of concavity of the side of the connecting portion 35 facing away from the seal 20, sewage can be prevented from remaining on the connecting portion 35, keeping the connecting portion 35 clean and reducing the growth of bacteria and other microorganisms.

[0062] Please refer to FIG. 5 . In some embodiments, the transmission mechanism 32 includes a rack 36 and a gear 37 meshing with the rack 36 . The rack 36 is disposed on the connecting shaft 33 , and the gear 37 is connected to the motor 31 .

[0063] In this way, the rotation of the motor 31 can be converted into reciprocating linear motion by the engagement of the gear 37 with the rack 36 , thereby driving the sealing member 20 to move back and forth linearly to open or close the opening 11 .

[0064] Specifically, the rack 36 can be arranged at the end of the shaft 34 away from the seal 20, and the gear 37 is coaxially arranged with the output end of the motor 31. The rack 36 and the gear 37 are formed by a plurality of teeth, which can be straight teeth or helical teeth. When the modules of the gear 37 and the rack 36 are equal and the pressure angles are equal, the gear 37 can mesh with the rack 36, thereby converting the rotation of the gear 37 into movement along the length direction of the rack 36. Taking Figure 5 as an example, when the gear 37 rotates clockwise, the seal 20 can move along the length direction of the rack 36 toward the opening 11 to close the opening 11; when the gear 37 rotates counterclockwise, the seal 20 can move along the length direction of the rack 36 away from the opening 11 to open the opening 11. The gear 37 and the rack 36 can be made of metal or plastic.

[0065] In some embodiments, the transmission mechanism 32 may be a screw transmission, a crank slider, a cam transmission, etc. The transmission mechanism 32 may convert the rotation of the motor 31 into a reciprocating linear motion.

[0066] Please refer to Figures 3 and 5. In some embodiments, the box body 10 has a receiving groove 13, which is formed on the outer surface 15 of the box body 10. The motor 31 and the gear 37 are arranged in the receiving groove 13, and the connecting shaft 33 passes through the side wall of the box body 10.

[0067] In this way, the motor 31 and the gear 37 can be installed outside the box body 10, preventing sewage from affecting the working performance of the motor 31 and improving the service life of the sewage tank 100.

[0068] Specifically, the shape of the accommodating groove 13 can be a rectangular parallelepiped, and the motor 31 can be fixed to the side wall of the accommodating groove 13 by fasteners such as bolts. A through hole 14 is formed at the bottom of the accommodating groove 13, and the rack 36 is arranged in the accommodating groove 13. The connecting part 35 is located in the storage cavity 12, and the shaft 34 is passed through the through hole 14 and connects the rack 36 and the connecting part 35.

[0069] Please refer to FIG. 5 . In some embodiments, the sewage tank 100 includes a limiting member 40 . The limiting member 40 is located in the movement direction of the sealing member 20 and is used to limit the movement stroke of the sealing member 20 .

[0070] In this way, the limiting member 40 can limit the range of movement of the sealing member 20 along the length direction of the rack 36, and automatic control can be achieved without the user manually operating the motor 31, which is simple to operate and easy to use.

[0071] Specifically, the limiting member 40 may be disposed in the accommodating groove 13 , and the limiting member 40 includes but is not limited to a photoelectric sensor switch, a Hall sensor, a micro switch 41 , and the like.

[0072] Referring to FIG. 5 , in some embodiments, the limit member 40 includes a micro switch 41 , which is triggered when the sealing member 20 is at the end of the movement stroke.

[0073] In this way, the micro switch 41 can limit the range of movement of the seal 20 along the length direction of the rack 36, and automatic control can be achieved without the user manually operating the motor 31, which is simple to operate and easy to use.

[0074] Specifically, the microswitch 41 can be set on the side of the rack 36 away from the gear 37. When the end of the rack 36 close to the seal 20 touches the microswitch 41, the microswitch 41 sends a signal and the motor 31 stops working; when the end of the rack 36 away from the seal 20 touches the microswitch 41, the microswitch 41 sends a signal and the motor 31 stops working.

[0075] Referring to FIG. 1 and FIG. 2 , in some embodiments, the opening 11 is provided at the bottom of the sewage tank 100 , and the sealing member 20 is configured to move along the height direction of the tank body 10 .

[0076] In this way, the opening 11 is set at the bottom of the sewage tank 100, so that the sewage can flow out from the bottom of the sewage tank 100 under the action of gravity. In addition, the seal 20 moves along the height direction of the box body 10, which can discharge garbage of various shapes in the box body 10, preventing the garbage from clogging the opening 11, eliminating the need for manual cleaning by the user, and improving the user experience.

[0077] Specifically, the opening 11 can extend through the bottom of the sewage tank 100. The diameter of the opening 11 can be gradually increased in size along the direction of sewage flow, and the diameter of the seal 20 can also be gradually increased in size along the direction of gravity. The speed of the motor 31 can be adjusted to adjust the speed at which the seal 20 rises and falls, thereby improving sewage discharge efficiency. Furthermore, the faster the seal 20 descends, the greater the pressure exerted by the seal 20 on the opening 11, facilitating the removal of waste clogged in the opening 11.

[0078] The application process of the sewage tank 100 of the embodiment of the present application can be as follows: when cleaning the sewage in the sewage tank 100, the motor 31 is started, and the motor 31 rotates to drive the gear 37 to rotate counterclockwise, and the seal 20 moves away from the opening 11 with the rack 36, opening the opening 11, and the sewage in the box body 10 flows out from the opening 11. When the end of the rack 36 close to the seal 20 touches the micro switch 41, the micro switch 41 sends a signal and the motor 31 stops working; when the sewage is cleaned, the motor 31 is started, and the motor 31 rotates to drive the gear 37 to rotate clockwise, and the seal 20 moves close to the opening 11 with the rack 36 to close the opening 11. When the end of the rack 36 away from the seal 20 touches the micro switch 41, the micro switch 41 sends a signal and the motor 31 stops working.

[0079] Implementation method 2:

[0080] 6 to 12 , the sewage tank 100 , the cleaning device 200 , and the cleaning system 1000 according to some embodiments of the present application are shown.

[0081] As shown in Figures 6-12, a sewage tank 100 according to some embodiments of the present application includes a housing 10, a seal 20, and a solenoid valve assembly 50. The housing 10 is provided with an opening 11. The seal 20 can move relative to the opening 11 to open or close the opening 11. The solenoid valve assembly 50 is connected to the seal 20. When the solenoid valve assembly 50 switches from a first state to a second state, it drives the seal 20 to open the opening 11. When the solenoid valve assembly 50 switches from the second state to the first state, it drives the seal 20 to close the opening 11. The first state is one of the power-on state and the power-off state, and the second state is the other of the power-on state and the power-off state.

[0082] The sewage tank 100 provided by the present invention comprises a housing 10, a sealing member 20, and a solenoid valve assembly 50. The housing 10 is provided with an opening 11, and the sealing member 20 is movable relative to the opening 11 to open or close the opening 11. It is understood that the sealing member 20 may be disposed on or off the housing 10, as long as it can open and close the opening 11. Specifically, the movement of the sealing member 20 can be driven by the solenoid valve assembly 50. For example, when the solenoid valve assembly 50 switches from a first state to a second state, the sealing member 20 opens the opening 11, and when the solenoid valve assembly 50 switches from the second state to the first state, the sealing member 20 closes the opening 11. The first state is either an energized state or an unenergized state, and the second state is the other of the energized state and the unenergized state. By providing the solenoid valve assembly 50 and the sealing member 20 to control the opening and closing of the opening 11, the sewage tank 100 is easier to clean than manual drainage methods. This also prevents the odor of the sewage from affecting the consumer experience during discharge. In addition, controlling the movement of the sealing member 20 by the solenoid valve assembly 50 can also increase the stability and reliability of the driving control compared to other driving schemes.

[0083] At the same time, since the present application uses electrical components to control the movement of the seal 20, it can be seamlessly connected to a fully automatic base station for use, thereby increasing the intelligence of the cleaning device 200.

[0084] In some embodiments, as shown in FIG. 7 , the seal 20 includes a lever 22 rotatably connected to the housing 10 ; a valve 24 disposed at one end of the lever 22 , and the other end of the lever 22 rotatably connected to the solenoid valve assembly 50 .

[0085] In this embodiment, the sealing member 20 includes a lever 22 and a valve 24. The lever 22 is rotatably connected to the housing 10. The valve 24 is disposed at one end of the lever 22, and the solenoid valve assembly 50 is disposed at the other end of the lever 22. The solenoid valve assembly 50 can thereby drive the lever 22 to rotate, thereby driving the valve 24 at one end of the lever 22 to open or close the opening 11. By controlling the opening or closing of the valve 24 using the principle of the lever 22, even when space is limited, the maximum opening of the valve 24 can be adjusted by simply adjusting the position of the rotational connection between the lever 22 and the housing 10, thereby meeting the user's needs. Furthermore, the lever 22-driven method is labor-saving, eliminating the need for a high-power drive component, thereby reducing costs.

[0086] In some embodiments, a sealing member is provided on the valve 24 to further seal the opening 11 and prevent water in the box 10 from leaking.

[0087] In some embodiments, as shown in Figure 9, a first mounting hole 222 is provided on the lever 22, and the lever 22 is rotatably connected to the solenoid valve assembly 50 through the first mounting hole 222; a second mounting hole 224 is provided on the lever 22, and the lever 22 is rotatably connected to the box body 10 through the second mounting hole 224.

[0088] In this embodiment, the lever 22 can be rotatably connected to the housing 10 and the solenoid valve assembly 50 via mounting holes, thereby enabling the solenoid valve assembly 50 to control the rotation of the lever 22. Specifically, a first mounting hole 222 and a second mounting hole 224 are provided on the lever 22. The lever 22 is rotatably connected to the solenoid valve assembly 50 via the first mounting hole 222 and is rotatably connected to the housing 10 via the second mounting hole 224. It will be understood that since mounting holes are provided on the lever 22, corresponding mounting shafts will be provided on the solenoid valve assembly 50 and the housing 10 to cooperate with the mounting holes to achieve a rotational connection.

[0089] In some embodiments, as shown in FIG. 9 and FIG. 11 , one of the first mounting hole 222 and the second mounting hole 224 is a circular hole, and the other of the first mounting hole 222 and the second mounting hole 224 is a waist-shaped hole.

[0090] In this embodiment, one of the first mounting hole 222 and the second mounting hole 224 is a circular hole, and the other is a waist-shaped hole, so that the solenoid valve assembly 50 can have a certain degree of freedom when it is rotatably connected to the waist-shaped hole of the lever 22, or the lever 22 has a certain degree of freedom when it is rotatably connected to the box body 10, thereby avoiding the solenoid valve assembly 50 from getting stuck in the process of driving the lever 22 to rotate, thereby improving the reliability and stability of the rotation.

[0091] The distance between the first mounting hole 222 and the second mounting hole 224 can be set according to actual needs to ensure the opening of the opening 11. Such a setting does not require additional space for setting parts.

[0092] In some embodiments, as shown in FIG. 7 , FIG. 8 and FIG. 10 , the solenoid valve assembly 50 includes: a magnetic conductive member 51 connected to the sealing member 20 ; and an electromagnet 52 disposed opposite to the magnetic conductive member 51 .

[0093] In this embodiment, the solenoid valve assembly 50 includes a magnetic permeable member 51 and an electromagnet 52. The magnetic permeable member 51 is connected to the sealing member 20, and the electromagnet 52 is arranged corresponding to the magnetic permeable member 51. When energized, the electromagnet 52 attracts the magnetic permeable member 51, thereby driving the sealing member 20 through the magnetic permeable member 51 to open or close the opening 11. The control of the electromagnet 52 and the magnetic permeable member 51 ensures a quick response when opening or closing the opening 11, improving the consumer experience.

[0094] In some embodiments, when the electromagnet 52 switches from the first state to the second state, the magnetic member 51 operates and drives the seal 20 to open the drain outlet. When the electromagnet 52 switches from the second state to the first state, the magnetic member 51 operates and drives the seal 20 to close the opening 11.

[0095] In this embodiment, when the electromagnet 52 switches from the first state to the second state, the magnetic member 51 is activated and drives the sealing member 20 to open the drain outlet. When the electromagnet 52 switches from the second state to the first state, the magnetic member 51 is activated and drives the sealing member 20 to close the drain outlet. Since the first state and the second state are respectively a power-on state and a power-off state, the present application controls the opening or closing of the opening 11 according to the power on and off of the electromagnet 52. Therefore, in actual application, the same power supply can be shared with the cleaning device 200 without the need for an additional power supply. In addition, this control method enables a rapid response to the opening or closing of the valve, thereby improving the consumer experience.

[0096] In some embodiments, the magnetic conductive member 51 is rotatably connected to the sealing member 20 .

[0097] In this embodiment, by rotatably connecting the magnetic member 51 and the sealing member 20, the positional relationship between the two can be changed when the magnetic member 51 drives the sealing member 20 to move, thereby preventing a jamming phenomenon when opening or closing the opening 11.

[0098] In some embodiments, a slide is further provided on the box body 10 , and the sealing member 20 is provided in the slide and can slide relative to the opening 11 to open or close the drain port.

[0099] In this embodiment, a slide can be set on the box body 10, and the seal 20 can be set in the slide, so that the drain outlet can be closed or opened by sliding the seal 20. Opening or closing the opening 11 by sliding can ensure stability and reliability when opening or closing the opening 11.

[0100] In some embodiments, a mounting portion is further provided on the box body 10 , the solenoid valve assembly 50 is provided on the mounting portion, the sealing member 20 is provided on the box body 10 , and one end of the sealing member 20 is connected to the solenoid valve assembly 50 .

The solenoid valve assembly 50 controls the movement of the seal 20 to open or close the drain outlet. By placing both the solenoid valve assembly 50 and the seal 20 on the water tank, the seal 20 is prevented from shifting relative to the opening 11, thereby ensuring a tight seal when the seal 20 closes the opening 11. Furthermore, when replacing or repairing the seal 20 or the solenoid valve assembly 50, the relative position of the replaced seal 20 and the opening 11 can be maintained, ensuring a tight seal when the opening 11 is closed.

[0102] In some embodiments, the sewage tank 100 further includes: a reset member 53 connected to the sealing member 20, and configured to return the sealing member 20 to the first position after the sealing member 20 moves from the first position to the second position; wherein, when the sealing member 20 is in the first position, the opening 11 is in one of a closed state and an open state, and when the sealing member 20 is in the second position, the opening 11 is in the other of a closed state and an open state.

[0103] In this embodiment, the sewage tank 100 further includes a reset member 53. The reset member 53 is connected to the sealing member 20 and is capable of returning the sealing member 20 to the first position after the sealing member 20 moves from the first position to the second position. When the sealing member 20 is in the first position, the opening 11 is in one of the closed and open states. When the sealing member 20 is in the second position, the opening 11 is in the other of the closed and open states. Therefore, the process of the sealing member 20 moving from the first position to the second position is also the process of controlling the sealing member 20 to open or close the opening 11. It will be understood that since the electromagnet 52 can generate a magnetic force to attract the magnetic member 51 when energized, but loses the magnetic force when de-energized, a reset member 53 can be provided to generate a force on the sealing member 20 to reset the sealing member 20 and close or open the opening 11.

[0104] In some embodiments, the return member 53 includes a spring.

[0105] In some embodiments, the restoration member 53 includes memory metal.

[0108] In some embodiments, the sealing member 20 can be rotated relative to the opening 11 to open or close the opening 11 .

[0109] In this embodiment, the sealing member 20 can open or close the opening 11 by rotating. The opening or closing method by rotating occupies little space and is more flexible when opening or closing the opening 11.

[0110] In some embodiments, the sealing member 20 is movably disposed on the box body 10 .

[0111] In this embodiment, the sealing member 20 may be movably disposed on the box body 10 , which is more conducive to opening or closing the opening 11 .

[0112] Referring to FIG. 12 , a cleaning device 200 according to an embodiment of the present application includes a main body 120 and a sewage tank 100 , and the sewage tank 100 is disposed on the main body 120 .

[0113] In this way, the sewage tank 100 can be completely disassembled and assembled from the main body 120 , which facilitates cleaning and maintenance of the sewage tank 100 and improves user experience.

[0114] Specifically, the cleaning device 200 can be a hand-push floor scrubber. A floor scrubber is a cleaning machine suitable for cleaning hard floors while sucking out dirty water and taking the dirty water away from the site. The floor cleaned by the floor scrubber can be a wooden floor, a tile floor, etc.

[0115] The main body 120 is capable of traveling on and cleaning the ground. The cleaning device 200 includes a clean water tank 110, which stores cleaning fluids such as clean water and detergent and supplies them to the main body 120. A dirty water tank 100 stores dirty water after the main body 120 cleans the ground. The clean water tank 110 and the dirty water tank 100 are detachably mounted on the main body 120. When the cleaning device 200 is moving forward, the dirty water tank 100 can be positioned in front of the main body 120, while the clean water tank 110 can be positioned behind the main body 120.

[0116] The following describes the working principle of the present application, taking the cleaning device 200 as a floor scrubber as an example:

[0117] When the sewage tank 100 needs to be discharged, the electromagnet 52 receives an electrical signal and moves upward, and the rotating shaft of the electromagnet 52 (the magnetic conductive member 51) moves upward. The rotating shaft of the electromagnet 52 drives the lever 22 to swing around the fulcrum of the lever 22 to rotate, and the sealing ring (valve 24) is separated from the water outlet of the sewage tank 100, the sewage discharge channel is opened, and the sewage is discharged smoothly.

[0118] When the sewage tank 100 and the electromagnet 52 finish draining, the electromagnet 52 cuts off the electrical signal, the magnetism disappears, and the magnetic conductive member 51 moves forward under the action of the spring force, and the valve 24 fits the opening 11 of the sewage tank 100, and the opening 11 is closed.

[0119] Referring to FIG. 12 , a cleaning system 1000 according to an embodiment of the present application includes a base station 300 and a cleaning device 200 , and the cleaning device 200 is selectively connected to the base station 300 .

[0120] In this way, the base station 300 can provide an accommodating space for the cleaning device 200 and charge the cleaning device 200 .

[0121] Specifically, the base station 300 includes a discharge circuit. When the cleaning device 200 contacts the base station 300, the cleaning device 200 obtains electrical energy from the discharge circuit of the base station 300 to charge the cleaning device 200. The base station 300 has a storage space for the cleaning device 200. When the cleaning device 200 is not in use, needs to be charged, or needs to clean sewage, the cleaning device 200 resides in the storage space. When the floor needs to be cleaned, the cleaning device 200 enters the storage space and moves along the floor to clean the floor.
