Technical Field

[0002] The present application relates to the field of household electrical appliances, and more specifically, to a floor scrubbing device, a base station, and a floor scrubbing component. Background Art

[0003] As people's living standards improve, they are increasingly pursuing an efficient and convenient cleaning experience. Floor scrubbers, as a new and popular household cleaning appliance, combine sweeping, mopping and washing in one. There are two main ways to discharge sewage from related floor scrubbers: 1) The user manually removes the sewage tank and cleans it manually. 2) Through an independent external sewage pipe, the sewage is discharged into the sewer through the base station. The manual cleaning method is cumbersome to operate, and there is a sewage odor and visual impact, which brings many inconveniences to users. The installation of an independent external sewage pipe makes the product structure complex, the product volume large, and the cost high.

[0004] Therefore, how to design a sewage disposal solution that does not require manual cleaning by the user and has a simple structure, small size and low cost has become an urgent problem to be solved.

[0008] The second objective of this application is to provide a base station.

[0009] The third object of the present application is to provide a floor scrubbing assembly.

[0010] The technical solution of the first aspect of the present application provides a floor washing equipment, including a sewage tank, a sewage suction pipe and a sewage discharge pipe. The sewage tank is used to collect sewage, the sewage suction pipe is connected to the sewage tank, the sewage suction pipe is used to guide the sewage into the sewage tank, the sewage discharge pipe connects the sewage tank and the sewage suction pipe, and the sewage discharge pipe is used to guide the sewage from the sewage tank to the sewage suction pipe, so that the sewage is discharged from the sewage suction pipe to the outside of the floor washing equipment.

[0011] In the floor washing equipment of the embodiment of the present application, by connecting the sewage discharge pipe with the sewage suction pipe, the sewage can flow into the sewage tank through the sewage suction pipe, and can also flow out of the sewage tank through the sewage discharge pipe and the sewage suction pipe. Combining the sewage suction pipe and the sewage discharge pipe makes the floor washing equipment simple in structure and reduces production costs.

[0012] The technical solution of the second aspect of the present application provides a base station for controlling the operation of a floor scrubbing device according to any one of the embodiments of the first aspect. The base station includes: a floor brush mounting portion for accommodating a floor brush assembly of the floor scrubbing device, and a drainage channel is provided on the floor brush mounting portion; when the floor scrubbing device is configured on the base station, the sewage inlet of the floor brush assembly is connected to the drainage channel.

[0013] The base station provided in this application is used to control the operation of the floor scrubbing equipment. After the floor scrubbing equipment is finished working, it can automatically return to the base station for charging, cleaning and other operations. Since the present application discharges sewage through the floor brush assembly, a drainage channel is provided on the floor brush mounting portion, and the drainage channel is connected to the user's home sewer, etc. In this way, when it is necessary to discharge sewage, the adjustment cover is directly opened, and the sewage in the sewage tank can flow along the sewage outlet, the sewage suction pipe and the floor brush assembly to the sewer channel, thereby realizing the automatic discharge of sewage in the sewage tank.

DETAILED DESCRIPTION

[0045] 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.

[0046] 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.

[0047] Please refer to Figures 1 and 2. The floor washing equipment 100 of the embodiment of the present application includes a sewage tank 2, a sewage suction pipe 20 and a sewage discharge pipe 30. The sewage tank 2 is used to collect sewage. The sewage suction pipe 20 is connected to the sewage tank 2. The sewage suction pipe 20 is used to guide the sewage to flow into the sewage tank 2. The sewage discharge pipe 30 connects the sewage tank 2 and the sewage suction pipe 20. The sewage discharge pipe 30 is used to guide the sewage to be discharged from the sewage tank 2 to the sewage suction pipe 20, so that the sewage is discharged from the sewage suction pipe 20 to the outside of the floor washing equipment 100.

[0048] In the floor cleaning equipment 100 of the embodiment of the present application, by connecting the sewage discharge pipe 30 with the sewage suction pipe 20, sewage can flow into the sewage tank 2 through the sewage suction pipe 20, and can also flow out of the sewage tank 2 through the sewage discharge pipe 30 and the sewage suction pipe 20. Combining the sewage suction pipe 20 and the sewage discharge pipe 30 makes the floor cleaning equipment 100 simple in structure and reduces production costs.

[0049] Specifically, the floor scrubber 100 may be a hand-push floor scrubber, which 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 that the floor scrubber cleans may be a wooden floor, a tile floor, or the like.

[0050] The sewage tank 2 may be shaped, but not limited to, circular or square. It may be formed using one or more of rotational molding, blow molding, injection molding, and sheet metal welding processes. The floor scrubber 100 includes a clean water tank 40, which stores cleaning fluids such as clean water and detergent. The sewage tank 2 is used to store wastewater after the floor scrubber 100 cleans the floor. If the floor scrubber 100 is traveling forward, the sewage tank 2 can be located in front of the floor scrubber 100, while the clean water tank 40 can be located behind the floor scrubber 100.

[0051] The sewage suction pipe 20 can be a circular cylindrical structure and can be made of plastic. The sewage suction pipe 20 is installed through the side wall of the sewage tank 2 and connected to the sewage tank 2. The sewage suction pipe 20 can be bent to reduce the flow rate of sewage in the sewage suction pipe 20 during sewage discharge, preventing sewage from splashing and contaminating the interior of the floor scrubber 100. The diameter and length of the sewage suction pipe 20 can be set according to the flow rate of the sewage.

[0052] The drain pipe 30 can be a circular cylindrical structure made of plastic and can be curved to reduce the flow rate of sewage in the drain pipe 30 and prevent it from splashing and contaminating the interior of the floor scrubber 100. The diameter and length of the drain pipe 30 can be adjusted based on the flow rate of the sewage. The outlet of the drain pipe 30 is connected to the sewage suction pipe 20.

[0053] Please refer to FIG. 2 . In some embodiments, the sewage tank 2 is formed with a first opening 26 and a receiving cavity 28 . The first opening 26 connects the receiving cavity 28 and the sewage pipe 30 . The first opening 26 is disposed at the bottom of the sewage tank 2 .

[0054] In this way, the sewage in the receiving cavity 28 can flow into the sewage pipe 30 from the bottom of the sewage tank 2 through the first opening 26 under the action of gravity, thereby achieving sewage discharge.

[0055] Specifically, the shape of the first opening 26 can be circular, rectangular, or the like. The size of the first opening 26 can be set according to actual needs to allow fluids and large particles to flow out through the second opening 141. The receiving chamber 28 is used to hold sewage within the sewage tank 2. The first opening 26 can extend through the bottom of the sewage tank 2, and the diameter of the first opening 26 can decrease in size along the flow direction of the sewage.

[0056] Please refer to Figure 2. In some embodiments, the floor cleaning equipment 100 includes a one-way valve 50. The one-way valve 50 includes a first elastic member 51 and a valve head 52. The first elastic member 51 is used to drive the valve head 52 to move. The valve head 52 can open or close the first opening 26 to control the one-way flow of sewage from the receiving chamber 28 to the sewage pipe 30.

[0057] In this way, the one-way valve 50 allows sewage to flow from the receiving chamber 28 to the sewage pipe 30 , while preventing sewage from flowing from the sewage pipe 30 to the receiving chamber 28 .

[0058] Specifically, the first elastic member 51 may be a spring, and the one-way valve 50 may be mounted at the first opening 26 via a threaded connection. When the sewage is at rest, the valve head 52, under the action of the first elastic member 51, closes the first opening 26. When the sewage flows from the receiving chamber 28 to the sewage pipe 30, the sewage overcomes the elastic force of the first elastic member 51, driving the valve head 52 to open the first opening 26, allowing the sewage to pass through. When the sewage flows from the sewage pipe 30 to the receiving chamber 28, the force exerted by the sewage on the one-way valve 50 aligns with the direction of the elastic force of the first elastic member 51, preventing the first opening 26 from opening. Therefore, the sewage cannot flow from the sewage pipe 30 to the receiving chamber 28.

[0059] Referring to FIG. 3 and FIG. 4 , in some embodiments, the floor scrubbing device 100 includes a control valve 60 disposed on the sewage pipe 30 . The control valve 60 is used to control the flow of sewage in the sewage pipe 30 .

[0060] In this way, the control valve 60 can allow sewage to flow in the sewage pipe 30 , or prevent sewage from flowing in the sewage pipe 30 .

[0061] Specifically, the control valve 60 can be an electric control valve, a pneumatic control valve, or a hydraulic control valve. When the control valve 60 closes the sewage pipe 30, it prevents sewage from flowing through the sewage pipe 30. When the control valve 60 opens the sewage pipe 30, it allows sewage to flow through the sewage pipe 30. The flow rate of sewage in the sewage pipe 30 can be adjusted by adjusting the area of ​​the sewage pipe 30 opened by the control valve 60. In some embodiments, the opening and closing of the sewage discharge can be automated by automatically controlling the control valve 60.

[0062] Please refer to Figure 2. In some embodiments, the floor cleaning equipment 100 includes a floor brush assembly 14. The floor brush assembly 14 is formed with a second opening 141. The second opening 141 connects the sewage suction pipe 20 and the external environment of the floor brush assembly 14. The second opening 141 is used to discharge sewage to the outside of the floor brush assembly 14.

[0063] In this way, sewage can be discharged from the sewage suction pipe 20 to the outside of the floor brush assembly 14 through the second opening 141 , thereby achieving sewage discharge, preventing sewage from contaminating the interior of the floor scrubbing device 100 , and improving the service life of the floor scrubbing device 100 .

[0064] Specifically, the floor brush assembly 14 is used to contact the floor and clean debris, dirt, water stains, and other garbage on the floor. A second opening 141 is provided at the bottom of the floor brush assembly 14. The shape of the second opening 141 can be rectangular, circular, etc. The size of the second opening 141 can be set according to actual needs so that liquids and large particles can flow out through the second opening 141.

[0065] Please refer to Figures 1 and 2. In some embodiments, the floor brush assembly 14 includes a base 142 and a cleaning member 143 disposed on the base 142. A second opening 141 is formed at the bottom of the base 142. The base 142 also has a third opening 146 spaced apart from the second opening 141. The third opening 146 is connected to the sewage suction pipe 20. The third opening 146 faces the cleaning member 143 and is used to guide the sewage sucked by the cleaning member 143 to the sewage suction pipe 20.

[0066] In this way, the cleaning member 143 can clean the ground, and sewage can flow out from the bottom of the base 142 through the second opening 141 , and sewage can also flow from the cleaning member 143 into the sewage suction pipe 20 through the third opening 146 .

[0067] Specifically, the base 142 can carry the cleaning member 143 , and the base 142 can separate the sewage suction pipe 20 from the ground to prevent sewage leakage from polluting the ground.

[0068] The cleaning member 143 is rotatably disposed on the base 142 . The cleaning member 143 may be a rag, a sweeping brush, a rolling brush, a roller, etc. The cleaning member 143 can contact the ground and wipe or clean the ground when the floor scrubbing device 100 is moving.

[0069] The third opening 146 is provided on the side of the cleaning member 143 facing the sewage suction pipe 20. The third opening 146 can be a regular shape such as a rectangle or a circle, or an irregular shape. The size of the third opening 146 can be set according to actual needs so that liquids and large particles can flow out through the third opening 146.

[0070] 3 and 5 , in some embodiments, the base 142 includes a closure member 147 , which includes a door body 1472 and a second rotating shaft 1474 connected to the door body 1472 . The door body 1472 is rotatably disposed at the second opening 141 via the second rotating shaft 1474 .

[0071] In this way, when the door body 1472 opens the second opening 141, sewage can flow out from the second opening 141 on the floor brush assembly 14, so that the floor cleaning equipment 100 does not need to disassemble the sewage tank 2 when discharging sewage, which is convenient to operate and reduces the production cost of the floor cleaning equipment 100.

[0072] The door body 1472 can be made of metal and can be shaped like an arc, rectangle, or the like. The door body 1472 can be larger than the second opening 141, and when the door body 1472 closes the second opening 141, it covers the second opening 141. The door body 1472 and the second rotating shaft 1474 can be integrally formed or fixedly connected by welding or other means. The second rotating shaft 1474 can be shaped like an arc. The door body 1472 can rotate about the second rotating shaft 1474 relative to the base 142. When the door body 1472 rotates away from the second opening 141, the second opening 141 is opened. When the door body 1472 rotates toward the second opening 141, the second opening 141 is closed. The sewage tank 2 can be positioned on the side opposite the second rotating shaft 1474.

[0073] The door 1472 can be disposed above the second opening 141. The door 1472 can rotate about the second rotation axis 1474 under the action of gravity to cover the second opening 141 and close the second opening 141. This allows the floor scrubber 100 to discharge wastewater without the use of electrical components, resulting in a simple structure, easy operation, and reduced production costs for the floor scrubber 100.

[0074] Please refer to Figures 2 and 5. In some embodiments, the floor brush assembly 14 is formed with a guide channel 148, which is connected to the second opening 141 and the third opening 146. When the door body 1472 opens the second opening 141, the door body 1472 abuts against the inner wall of the guide channel 148 to separate the second opening 141 and the third opening 146.

[0075] In this way, the sewage can be guided from the third opening 146 to the sewage suction pipe 20 through the diversion channel 148, and the sewage can also be guided from the sewage suction pipe 20 to the second opening 141. In addition, the door body 1472 abuts against the inner wall of the diversion channel 148 to prevent sewage from flowing from the sewage suction pipe 20 to the third opening 146.

[0076] Specifically, the diversion channel 148 can be a square pipe and is connected to the sewage suction pipe 20. When the door 1472 opens the second opening 141, the diversion channel 148 connects the sewage suction pipe 20 and the second opening 141, and sewage flows from the sewage suction pipe 20 to the second opening 141. The door 1472 abuts against the inner wall of the diversion channel 148, preventing sewage from flowing through the gap between the door 1472 and the diversion channel 148 to the third opening 146. When the door 1472 closes the second opening 141, the diversion channel 148 connects the sewage suction pipe 20 and the third opening 146, and sewage flows from the third opening 146 to the sewage suction pipe 20.

[0077] Referring to FIG. 6 and FIG. 7 , in some embodiments, the floor brush assembly 14 includes a reset member 149 disposed on the base 142 . The reset member 149 is used to drive the door 1472 to close the second opening 141 .

[0078] In this way, the restoring member 149 can provide a driving force to improve the fitting strength between the door body 1472 and the base 142 , thereby preventing sewage from flowing out of the second opening 141 .

[0079] Specifically, the reset member 149 can be fixed above the second opening 141 . When the door body 1472 rotates close to the second opening 141 under the action of gravity, the reset member 149 can drive the door body 1472 to fit the door body 1472 with the base 142 to close the second opening 141 .

[0080] Please refer to FIG. 7 . In some embodiments, the reset member 149 is a magnetic member 145 . The magnetic member 145 is disposed on a side opposite to the second rotating shaft 1474 . The door 1472 and the magnetic member 145 are magnetically attracted to each other.

[0081] In this way, the magnetic member 145 is attracted to the door body 1472 by magnetism, so that the door body 1472 can automatically close the second opening 141 without the help of electrical components and without manual operation by the user. The floor scrubbing device 100 has a simple structure and low cost.

[0082] Specifically, the magnetic member 145 may be a magnetic metal and may be in a block or strip structure. The length of the magnetic member 145 may be less than the length of the second rotating shaft 1474, greater than the length of the second rotating shaft 1474, or equal to the length of the second rotating shaft 1474.

[0083] In some embodiments, the reset member 149 is a second elastic member, and the second elastic member is used to drive the door body 1472 to reset.

[0084] In this way, the second elastic member can provide elastic force to reset the door body 1472, so that the door body 1472 can automatically close the second opening 141 without the help of electrical components and manual operation by the user. The floor scrubbing device 100 has a simple structure and low cost.

[0085] Specifically, the second elastic member can be a spring, one end of the spring is connected to the base 142, and the other end is connected to the door body 1472. When the door body 1472 opens the second opening 141, the spring is in a stretched state, providing a stretching force to drive the door body 1472 to reset. When the door body 1472 closes the second opening 141, the spring returns to its original state.

[0086] 6 and 7 , in some embodiments, the floor scrubbing device 100 includes a seal 140 , which is configured to seal a gap between the door 1472 and the base 142 when the door 1472 closes the second opening 141 .

[0087] In this way, the seal 140 can seal the gap between the door body 1472 and the base 142, improve the sealing performance of the door body 1472 and the base 142, and prevent sewage from flowing out of the gap and polluting the ground.

[0088] Specifically, the seal 140 can be made of a rubber material, and the contact surface between the door 1472 and the seal 140 can be stepped, inclined, or vertical. The width of the seal 140 can be greater than the width of the gap between the door 1472 and the base 142, or can be equal to the width of the gap between the door 1472 and the base 142.

[0089] Seal 140 can be secured to door body 1472 along its circumference to prevent sewage from flowing out of the circumference of door body 1472 and contaminating the ground. The number of seals 140 can be one, two, or three. Seal 140 can be composed of multiple strips or integrally formed. Seal 140 can be secured to the side opposite second rotating shaft 1474 and to both sides of second rotating shaft 1474. When door body 1472 opens second opening 141, seal 140 abuts the inner wall of diversion channel 148, separating second opening 141 from third opening 146.

[0090] The application process of the floor scrubbing equipment 100 of the embodiment of the present application can be as follows: when the floor scrubbing equipment 100 is working, the door body 1472 closes the second opening 141, and the sewage on the cleaning component 143 flows from the third opening 146 through the diversion channel 148 and the sewage suction pipe 20 to the accommodating cavity of the sewage tank 2; when cleaning the sewage in the accommodating cavity, the door body 1472 opens the second opening 141, and the sewage flows from the first opening 26 through the sewage discharge pipe 30, the sewage suction pipe 20 and the diversion channel 148 to the second opening 141.

[0091] Referring to FIG. 7 , FIG. 8 and FIG. 9 , in some embodiments, when the floor scrubbing device 100 is placed on the base station 200 , the protrusion 230 on the base station 200 lifts the door 1472 so that the door 1472 opens the second opening 141 .

[0092] In this way, the protrusion 230 can lift the door body 1472 to open the second opening 141 , so that sewage can flow out of the second opening 141 .

[0093] Specifically, protrusion 230 can be made of plastic and can be shaped like a triangular prism or a semi-cylinder. Protrusion 230 protrudes from the surface of base station 200. By adjusting the height of protrusion 230 from the surface of base station 200 and the distance between protrusion 230 and second rotating shaft 1474, the angle of door 1472 can be set, thereby adjusting the flow rate of sewage into second opening 141 and allowing fluids and large particulate matter to enter second opening 141. In some embodiments, protrusion 230 can be controlled by a system with electric components to achieve automatic adjustment of the opening angle of door 1472.

[0094] Referring to FIG. 1 , a floor scrubbing assembly 1000 according to an embodiment of the present application includes a base station 200 and a floor scrubbing device 100 , and the floor scrubbing device 100 is selectively connected to the base station 200 .

[0095] In this way, the base station 200 can provide an accommodating space for the floor scrubbing device 100 and charge the floor scrubbing device 100 .

[0096] Specifically, the base station 200 includes a discharge circuit. When the floor scrubber 100 contacts the base station 200, the floor scrubber 100 obtains electrical energy from the discharge circuit of the base station 200 to charge the floor scrubber 100. The base station 200 has a storage space for the floor scrubber 100. When the floor scrubber 100 is not in use, needs to be charged, or needs to clean dirty water, the floor scrubber 100 resides in the storage space. When the floor needs to be cleaned, the floor scrubber 100 enters the storage space and moves along the floor to clean it.

[0097] Referring to Figures 2 and 9, in some embodiments, the base station 200 is provided with a flow channel 240 that interfaces with the second opening 141, and the protrusion 230 is at least partially disposed in the flow channel 240. The protrusion 230 can guide the sewage to flow out of the base station 200 through the flow channel 240, thereby keeping the base station 200 clean and preventing the sewage from remaining in the base station 200 and breeding bacteria and other microorganisms.

[0098] Specifically, the flow channel 240 may be a circular pipe, one end of the flow channel 240 is connected to the second opening 141 , and the other end may be connected to the floor drain to guide the sewage from the second opening 141 to the floor drain.

[0099] Please refer to Figures 10 and 11. The floor cleaning equipment 100 of the embodiment of the present application includes a sewage tank 2, a floor brush assembly 14 and a closure 147. The sewage tank 2 is used to collect sewage. The floor brush assembly 14 is formed with a second opening 141. The second opening 141 connects the sewage tank 2 and the external environment of the floor brush assembly 14. The closure 147 includes a door body 1472 and a second rotating shaft 1474 connected to the door body 1472. The door body 1472 is rotatably arranged at the second opening 141 through the second rotating shaft 1474.

[0100] In the floor cleaning device 100 of the embodiment of the present application, when the door body 1472 opens the second opening 141, sewage can flow out from the second opening 141 on the floor brush assembly 14, so that the floor cleaning device 100 does not need to disassemble the sewage tank 2 when discharging sewage, which is convenient to operate and reduces the production cost of the floor cleaning device 100.

[0101] Specifically, the floor scrubber 100 may be a hand-push floor scrubber, which 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 that the floor scrubber cleans may be a wooden floor, a tile floor, or the like.

[0102] The floor scrubber 100 includes a clean water tank 40, which stores cleaning fluids such as clean water and detergent. This clean water tank 40 is configured to supply the cleaning fluid to the floor brush assembly 14, thereby enhancing the cleaning capability of the floor brush assembly 14 and further improving the efficiency of the floor scrubber 100. The dirty water tank 2 stores dirty water left by the floor scrubber assembly 14. If the floor scrubber 100 is traveling forward, the dirty water tank 2 can be located in front of the floor scrubber 100, while the clean water tank 40 can be located in the rear.

[0103] The floor brush assembly 14 is used to contact the floor and clean debris, dirt, water stains, and other debris on the floor. A second opening 141 is provided at the bottom of the floor brush assembly 14. The shape of the second opening 141 can be rectangular, circular, etc. The size of the second opening 141 can be set according to actual needs to allow liquids and large particles to flow out through the second opening 141.

[0104] The door body 1472 can be made of metal and can be shaped like an arc, rectangle, or the like. The door body 1472 can be larger than the second opening 141, and when the door body 1472 closes the second opening 141, it covers the second opening 141. The door body 1472 and the second rotating shaft 1474 can be integrally formed or fixedly connected by welding or other means. The second rotating shaft 1474 can be shaped like an arc. The door body 1472 can rotate about the second rotating shaft 1474 relative to the base 142. When the door body 1472 rotates away from the second opening 141, the second opening 141 is opened. When the door body 1472 rotates toward the second opening 141, the second opening 141 is closed. The sewage tank 2 can be positioned on the side opposite the second rotating shaft 1474.

[0105] In some embodiments, the door 1472 can close the second opening 141 under the action of gravity.

[0106] In this way, the floor scrubbing device 100 can discharge sewage without the aid of electrical components, has a simple structure, is easy to operate, and reduces the production cost of the floor scrubbing device 100.

[0107] Specifically, the door body 1472 may be disposed above the second opening 141 . The door body 1472 may rotate around the second rotation axis 1474 under the action of gravity to cover the second opening 141 to close the second opening 141 .

[0108] Referring to FIG. 10 and FIG. 11 , in some embodiments, the floor scrubbing device 100 includes a water pipe 70 . The water pipe 70 connects the sewage tank 2 and the floor brush assembly 14 . The water pipe 70 is used to guide the sewage from the sewage tank 2 to flow toward the second opening 141 .

[0109] In this way, the sewage can be guided from the sewage tank 2 to the second opening 141 through the water pipe 70 to achieve sewage discharge.

[0110] Specifically, the water pipe 70 can be a circular cylindrical structure made of plastic. It can be located on the side opposite the second rotating shaft 1474, with one end connected to the sewage tank 2 and the other end docked with the second opening 141. The sewage tank 2 is located above the floor brush assembly 14, and sewage can flow from the sewage tank 2 to the second opening 141 of the floor brush assembly 14 along the water pipe 70 under the action of gravity. The water pipe 70 can be curved to reduce the flow rate of sewage in the water pipe 70 and prevent it from splashing and contaminating the interior of the floor scrubbing device 100. The diameter and length of the water pipe 70 can be set according to the flow rate of the sewage.

[0111] Referring to FIG. 10 and FIG. 11 , in some embodiments, the floor brush assembly 14 includes a base 142 and a cleaning member 143 disposed on the base 142 , and the second opening 141 is formed at the bottom of the base 142 .

[0112] In this way, the cleaning member 143 can clean the ground, and the sewage can flow out from the bottom of the base 142 through the second opening 141 .

[0113] Specifically, the base 142 may include the bottom and upper shell of the floor brush assembly 14 , the base 142 may carry the cleaning member 143 , and the base 142 may separate the water pipe 70 from the floor to prevent sewage leakage from contaminating the floor.

[0114] The cleaning member 143 is rotatably disposed on the base 142 . The cleaning member 143 may be a rag, a sweeping brush, a rolling brush, a roller, etc. The cleaning member 143 can contact the ground and wipe or clean the ground when the floor scrubbing device 100 is moving.

[0115] Referring to FIG. 10 and FIG. 11 , in some embodiments, the floor brush assembly 14 includes a retaining member 144 disposed on the base 142 , and the retaining member 144 is used to drive the door 1472 to close the second opening 141 .

[0116] In this way, the retaining member 144 can provide a driving force to improve the fitting strength between the door body 1472 and the base 142 , thereby preventing sewage from flowing out of the second opening 141 .

[0117] Specifically, the retaining member 144 can be fixed above the second opening 141. When the door body 1472 rotates close to the second opening 141 under the action of gravity, the retaining member 144 can drive the door body 1472 to fit the door body 1472 with the base 142 to close the second opening 141.

[0118] Please refer to FIG. 11 . In some embodiments, the retaining member 144 is a magnetic member 145 . The magnetic member 145 is disposed on a side opposite to the second rotating shaft 1474 . The door 1472 and the magnetic member 145 are magnetically attracted to each other.

[0119] In this way, the magnetic member 145 is attracted to the door body 1472 by magnetism, so that the door body 1472 can automatically close the second opening 141 without the help of electrical components and without manual operation by the user. The floor scrubbing device 100 has a simple structure and low cost.

[0120] Specifically, the magnetic member 145 may be a magnetic metal and may be in a block or strip configuration. The length of the magnetic member 145 may be shorter than the length of the second rotating shaft 1474, longer than the length of the second rotating shaft 1474, or even equal to the length of the second rotating shaft 1474.

[0121] In some embodiments, the retaining member 144 is an elastic member, and the elastic member is used to drive the door body 1472 to reset.

[0122] In this way, the elastic member can provide elastic force to reset the door body 1472, so that the door body 1472 can automatically close the second opening 141 without the help of electrical components and manual operation by the user. The floor scrubbing device 100 has a simple structure and low cost.

[0123] Specifically, the elastic member can be a spring, one end of the spring is connected to the base 142, and the other end is connected to the door body 1472. When the door body 1472 opens the second opening 141, the spring is in a stretched state, providing a stretching force to drive the door body 1472 to reset. When the door body 1472 closes the second opening 141, the spring returns to its original state.

[0124] 10 and 11 , in some embodiments, the floor scrubbing device 100 includes a seal 140 , which is configured to seal a gap between the door 1472 and the base 142 when the door 1472 closes the second opening 141 .

[0125] In this way, the seal 140 can seal the gap between the door body 1472 and the base 142, improve the sealing performance of the door body 1472 and the base 142, and prevent sewage from flowing out of the gap and polluting the ground.

[0126] Specifically, the seal 140 can be made of a rubber material, and the contact surface between the door 1472 and the seal 140 can be stepped, inclined, or vertical. The width of the seal 140 can be greater than the width of the gap between the door 1472 and the base 142, or can be equal to the width of the gap between the door 1472 and the base 142.

[0127] Referring to FIG. 11 , in some embodiments, the seal 140 is fixed to the door body 1472 along the circumference of the door body 1472 .

[0128] In this way, the seal 140 can prevent sewage from flowing out from the circumference of the door body 1472 and polluting the ground.

[0129] Specifically, the number of the sealing member 140 can be one, two, or three. The sealing member 140 can be formed by splicing multiple strip structures or integrally formed. The sealing member 140 can be fixed on the side opposite to the second rotating shaft 1474 and on both sides of the second rotating shaft 1474.

[0130] 10 and 12 , a floor scrubbing assembly 1000 according to an embodiment of the present application includes a base station 200 and a floor scrubbing device 100 .

[0131] In this way, the base station 200 can provide an accommodating space for the floor scrubbing device 100 and charge the floor scrubbing device 100 .

[0132] Specifically, the base station 200 includes a discharge circuit. When the floor scrubber 100 contacts the base station 200, the floor scrubber 100 obtains electrical energy from the discharge circuit of the base station 200 to charge the floor scrubber 100. The base station 200 has a storage space for the floor scrubber 100. When the floor scrubber 100 is not in use, needs to be charged, or needs to clean dirty water, the floor scrubber 100 resides in the storage space. When the floor needs to be cleaned, the floor scrubber 100 enters the storage space and moves along the floor to clean it.

[0133] Referring to FIG. 12 and FIG. 13 , in some embodiments, the base station 200 is provided with a protrusion 230 . When the floor scrubbing device 100 is placed on the base station 200 , the protrusion 230 lifts the door 1472 so that the door 1472 opens the second opening 141 .

[0134] In this way, the protrusion 230 can lift the door body 1472 to open the second opening 141 , so that sewage can flow out of the second opening 141 .

[0135] Specifically, protrusion 230 can be made of plastic and can be shaped like a triangular prism or a semi-cylinder. Protrusion 230 protrudes from the surface of base station 200. By adjusting the height of protrusion 230 from the surface of base station 200 and the distance between protrusion 230 and second rotating shaft 1474, the angle of door 1472 can be set, thereby adjusting the flow rate of sewage into second opening 141 and allowing fluids and large particulate matter to enter second opening 141. In some embodiments, protrusion 230 can be controlled by a system with electric components to achieve automatic adjustment of the opening angle of door 1472.

[0136] Referring to FIG. 10 and FIG. 13 , in some embodiments, the base station 200 is provided with a flow channel 240 docking with the second opening 141 , and the protrusion 230 is at least partially disposed in the flow channel 240 .

[0137] In this way, the protrusion 230 can guide the sewage to flow out of the base station 200 through the flow channel 240, thereby keeping the base station 200 clean and preventing the sewage from remaining in the base station 200 and breeding microorganisms such as bacteria.

[0138] Specifically, the flow channel 240 may be a circular pipe, one end of the flow channel 240 is connected to the second opening 141 , and the other end may be connected to the floor drain to guide the sewage from the second opening 141 to the floor drain.

[0139] The application process of the floor scrubbing assembly 1000 according to the embodiment of the present application can be as follows: When the floor scrubbing device 100 is finished working, it is placed on the base station 200. The protrusion 230 on the base station 200 lifts the door 1472, opening the second opening 141. The sewage in the sewage tank 2 flows from the sewage tank 2 along the water pipe 70 to the second opening 141, and then flows out of the base station 200 through the flow channel 240. When the floor scrubbing device 100 needs to work again, it is removed from the base station 200. The door 1472 fits against the base 142 under its own weight and the magnetic attraction of the magnetic member 145, closing the second opening 141. The sealing member 140 on the door 1472 seals the gap between the door 1472 and the base 142, preventing the sewage in the floor scrubbing device 100 from flowing out and contaminating the ground.

[0140] As shown in Figures 14 to 26, an embodiment of the present application provides a floor scrubbing device, including a body 1, a sewage tank 2, a sewage pipe 30 and an adjustment component 18.

[0141] As shown in Figures 14, 15, and 26, the main body 1 includes a sewage suction pipe 20. A sewage tank 2 is mounted on the main body 1 and is provided with a sewage outlet 22 and a sewage suction port 24. The sewage suction port 24 is connected to the sewage suction pipe 20. One end of a sewage pipe 30 is connected to the sewage outlet 22, and the other end of the sewage pipe 30 is connected to the sewage suction pipe 20. An adjustment assembly 18 (specifically, an on-off valve, etc.) is provided at the junction of the sewage pipe 30 and the sewage outlet 22 to connect or disconnect the sewage pipe 30 with the sewage outlet 22.

[0142] The floor scrubbing device provided herein can be specifically a floor scrubber or other device. The floor scrubbing device comprises a body 1, a sewage tank 2, a sewage pipe 30, and an adjustment assembly 18. The body 1 is the main structure of the floor scrubbing device and generally includes a floor brush assembly 14, a sewage suction line, and other components. The sewage tank 2 is used to collect sewage generated during floor cleaning and other processes. It includes a sewage suction port 24 for collecting sewage and a sewage discharge port 22 for discharging sewage. Specifically, the body 1 includes a sewage suction pipe 20, through which sewage generated during floor cleaning and other processes can be input into the sewage tank 2 for collection. The sewage discharge port 22 is used to drain water from the sewage tank 2. Since the sewage discharge port 22 is connected to the sewage suction pipe 20 via the sewage discharge pipe 30, sewage in the sewage tank 2 can be discharged into the sewage suction pipe 20 through the sewage discharge port 22. The adjustment assembly controls the passage of the sewage discharge port 22, opening and closing the sewage discharge port 22 to connect or disconnect the sewage tank 2 and the sewage suction pipe 20. Specifically, when cleaning the floor, for example, the drain outlet 22 can be closed by adjusting the assembly, disconnecting the suction pipe 20 from the drain outlet 22. Water on the floor can then flow into the sewage tank 2 through the suction pipe 20. After cleaning, when the sewage in the sewage tank 2 needs to be drained, the drain outlet 22 can be opened by adjusting the assembly, connecting the suction pipe 20 and the drain outlet 22. Water in the sewage tank 2 can then be drained through the drain outlet 22, the drain outlet 22, and the suction pipe 20. This solution utilizes the existing suction pipe 20 for sewage discharge, meaning that the suction pipe 20 can serve as both a sewage suction channel and a sewage discharge channel. This eliminates the need for dedicated drainage piping, thus simplifying the overall structure of the product, reducing its size, and lowering its cost. Furthermore, this solution eliminates the need for the user to manually remove and clean the sewage tank 2, simplifying user operations and improving the user experience.

[0143] Among them, the sewage pipe 30 can be specifically a connecting pipe set independently of the fuselage 1, or it can be a channel structure formed by the fuselage 1 (as shown in Figures 14 and 15). Its specific form is not limited, as long as the sewage outlet 22 and the sewage suction pipe 20 can be connected.

[0144] In some embodiments, as shown in Figures 14 and 21 , the sewage tank 2 is mounted in front of the body 1. This placement allows the user to visually observe the amount of sewage in the tank 2, preventing the possibility of excessive sewage in the tank 2 being left undischarged. The sewage outlet 22 connects to the suction pipe 20 at the front of the product, allowing the user to visually observe the sewage discharge process.

[0145] Furthermore, installing the sewage tank 2 in the front of the machine body 1 also increases the space behind the machine body 1, thereby facilitating user operation. Furthermore, compared to installing the sewage tank 2 in the front of the machine body 1, this arrangement also prevents users from frequently bumping into the sewage tank 2 while using the floor scrubber. Furthermore, this arrangement fully utilizes the space in front of the machine body 1, making the overall structural layout of the device more rational. This avoids the situation where the machine body 1 is light at the front and heavy at the back, as would be the case if the sewage tank 2, clean water tank, etc., were all concentrated at the rear of the machine body 1.

[0146] Among them, when using the floor scrubber, the side of the body 1 close to the user is the rear, and the surface located in the front side of the travel direction is the front of the body 1. Generally speaking, when using the floor scrubber, the side of the body 1 provided with the floor brush assembly 14 is the front, and the side of the body 1 away from the floor brush assembly 14 is the rear.

[0147] In some embodiments, as shown in FIG16 , the floor scrubbing device includes an adjustment cover 3 . The adjustment cover 3 is installed at the drain outlet 22 and can move relative to the drain outlet 22 to open or close the drain outlet 22 .

[0148] In this embodiment, the adjustment cover 3 can be rotatably or slidably mounted on the sewage tank 2 or the body 1. By moving the adjustment cover 3, the sewage outlet 22 can be opened to connect and disconnect the sewage tank 2 and the sewage suction pipe 20.

[0149] In addition, the regulating component can also be a valve (not shown) provided in the sewage pipe 30, through which the sewage pipe 30 can be connected or cut off. Furthermore, the valve can be a solenoid valve or a mechanical valve.

[0150] In some embodiments, as shown in FIG. 17 , the floor scrubbing device further includes: a first rotating shaft 8 , and the adjusting cover 3 is rotatably mounted on the body 1 and / or the sewage tank 2 via the first rotating shaft 8 .

[0151] In this embodiment, the adjustable cover 3 is rotatably mounted on the body 1 and / or the sewage tank 2 via the first rotating shaft 8. This means that the adjustable cover 3 can be rotated to open the sewage outlet 22 of the sewage tank 2. Compared to a sliding arrangement, a rotating arrangement occupies less space and has a simpler structure. Of course, in other embodiments, the adjustable cover 3 can also be a sliding cover that rotates or slides radially along the sewage outlet 22.

[0152] When the floor scrubber is sucking in waste, the wastewater flows along a first route L1 as shown in FIG14 . When the floor scrubber is discharging waste, the wastewater flows along a second route L2 as shown in FIG15 . Comparing FIG14 and FIG15 , it can be seen that both routes pass through the wastewater suction pipe 20 .

[0153] In some embodiments, as shown in FIG. 15 and FIG. 16 , the body 1 includes a floor brush assembly 14 . The floor brush assembly 14 is provided with a sewage inlet, which is connected to the sewage suction pipe 20 .

[0154] In this embodiment, the body 1 includes a floor brush assembly 14. The floor brush assembly 14 is used to contact the ground to clean it. The floor brush assembly 14 is provided with a sewage inlet, through which sewage on the ground can enter the sewage suction pipe 20 and then flow into the sewage tank 2. When the sewage in the sewage tank 2 needs to be discharged, the water in the sewage outlet 22 enters the sewage suction pipe 20 and is then discharged by the floor brush. This method fully utilizes the sewage suction pipe 20 for sewage discharge, thereby simplifying the overall structure of the product.

[0155] In some embodiments, the floor scrubbing device further includes a drive assembly connected to the adjustable cover 3 to drive the adjustable cover 3 to open or close the drain outlet 22. The drive assembly can be specifically a combination of the motor 5 and the crank-connecting rod assembly 6 shown in FIG24. Of course, the drive assembly can also be powered by a pneumatic cylinder, an oil cylinder, or the like.

[0156] In some embodiments, as shown in FIG. 24 , the floor scrubbing equipment further includes a first control device 4 connected to the driving assembly, capable of controlling the operation of the driving assembly according to the mode of the floor scrubbing equipment to drive the adjustment cover 3 to open or close the drain outlet 22 .

[0157] In this embodiment, the drive assembly serves as a power source, driving the adjustable cover 3 to open and close the drain outlet 22. The control device controls the operation of the drive assembly based on the product's operating mode, thereby controlling the position of the adjustable cover 3 and, in turn, the state of the drain outlet 22. This allows the drain outlet 22 to be opened and closed based on the product's actual operating mode. For example, when the product is in drain mode, the drain outlet 22 can be opened, while when the product is in cleaning mode, the drain outlet 22 can be closed.

[0158] When the floor scrubbing device is equipped with a base station 200 , the control device may be provided on the base station 200 . In this case, the first control device 4 may be provided on the body 1 .

[0159] In some embodiments, as shown in Figures 17, 18 and 19, the driving assembly includes: a motor 5; a transmission assembly connected to the motor 5, the motor 5 rotates along a first direction (for example, the direction indicated by the arrow in Figure 22), and the transmission assembly can move from the first position to the second position, and drive the adjusting cover 3 to open the sewage outlet 22; the motor 5 rotates along the second direction (for example, the direction opposite to the direction indicated by the arrow in Figure 22), and the transmission assembly can return from the second position to the first position.

[0160] In this embodiment, the motor 5 serves as a power assembly, driving the transmission assembly to open and close the adjustable cover 3. The transmission assembly is initially positioned at the first position; when it moves to the second position, the adjustable cover 3 is opened. The motor 5 can rotate forward and reverse. Forward rotation of the motor 5 moves the transmission assembly from the first position to the second position, thereby driving the adjustable cover 3 from the third position to the fourth position, thereby opening the adjustable cover 3. Reverse rotation of the motor 5 returns the transmission assembly to the first position, thereby removing the force applied to the adjustable cover 3 by the transmission assembly, allowing the adjustable cover 3 to return to its initial installation position, thereby closing the sewage outlet 22.

[0161] In some embodiments, as shown in Figures 17, 18 and 19, the transmission assembly includes: a crank-connecting rod assembly 6, which is installed on the fuselage 1 and / or the sewage tank 2 and is connected to the adjusting cover 3. When the crank-connecting rod assembly 6 is actuated, it can drive the adjusting cover 3 to open or close the sewage outlet 22.

[0162] In this embodiment, the opening and closing control of the regulating cover 3 can be achieved through the crank-connecting rod assembly 6. The crank-connecting rod assembly 6 has a simple structure, a small volume and is relatively common, thereby simplifying the structure of the entire transmission assembly and reducing the cost of the transmission assembly.

[0163] In some embodiments, as shown in Figures 17, 18 and 19, the crank-connecting rod assembly 6 includes: a connecting rod 64, which is connected to the adjusting cover 3 and is provided with a slide groove 642; a crank 62, which is rotatably connected to the fuselage 1 or the sewage tank 2, and is provided with a slider 622, which is slidably installed in the slide groove 642.

[0164] By rotating the crank 62, the slider 622 can slide in the chute 642, thereby driving the connecting rod 64 to extend and retract through the cooperation between the chute 642 and the slider 622. When the adjustable cover 3 needs to be opened, the connecting rod 64 can be controlled to extend to open the adjustable cover 3. When the adjustable cover 3 needs to be closed, the connecting rod 64 can be controlled to retract to allow the adjustable cover 3 to return to its original position, thereby temporarily closing the sewage outlet 22.

[0165] In some embodiments, as shown in Figures 17, 18 and 19, the transmission assembly also includes: a turntable, which can be rotatably mounted on the fuselage 1 or the sewage tank 2 and is connected to the motor 5, and the crank 62 is set on the turntable; the crank 62 and the turntable are detachably connected, or the crank 62 and the turntable are an integrated structure.

[0166] In this embodiment, the crank 62 is disposed on a turntable, so that the rotation of the turntable can drive the crank 62 to rotate, thereby realizing the opening and closing of the adjustable cover 3. The rotation of the crank 62 driven by the turntable can improve the stability and reliability of the rotation compared to the crank 62 rotating alone, thereby improving the reliability of the entire device.

[0167] Among them, the crank 62 and the turntable can be detachably connected, or the crank 62 and the turntable are an integrated structure, that is, the crank 62 and the turntable are the same part, and the two can be integrally formed. At this time, the turntable is used as the crank 62, that is, it can be understood that the crank 62 is set to a disc-shaped structure. This setting can make the crank 62 rotate more smoothly, thereby improving the reliability of the valve core movement.

[0168] Specifically in actual application, a protrusion that does not coincide with the center of the turntable can be set on the turntable to be used as a slider 622, so that a crank 62 structure is formed between the protrusion and the center of the turntable, thereby realizing the integrated setting of the turntable and the crank 62.

[0169] In some embodiments, as shown in Figures 17 to 20, the turntable includes: a first gear 624, which can be rotatably mounted on the fuselage 1 or the sewage tank 2, and the motor 5 can drive the first gear 624 to rotate, the crank 62 is set on the first gear 624, and the slider 622 deviates from the rotation center of the first gear 624.

[0170] In this embodiment, the turntable includes a first gear 624. The crank 62 is arranged on the first gear 624, and the slider 622 on the crank 62 is also arranged on the first gear 624. When the motor 5 drives the first gear 624 to rotate, the connecting rod 64 can be driven to move. It can be understood that the gear transmission has high reliability and can achieve fine-tuning, thereby driving the connecting rod 64 to move through the first gear 624, thereby improving the stability and reliability of the movement of the connecting rod 64. In addition, considering that the driving device such as the motor 5 generally provides a reduction mechanism when driving the turntable to rotate, and the gear reduction mechanism is very common, the first gear 624 here can be a gear in the gear reduction mechanism, so that the crank 62 can be driven to rotate by the gear in the reduction mechanism, thereby further simplifying the structure of the product.

[0171] In some possible designs, the length of the crank 62 is smaller than the radius of the first gear 624 , thereby preventing the crank 62 from extending beyond the first gear 624 .

[0172] In some embodiments, as shown in FIG. 20 , the floor scrubbing device further includes: a second gear 7 connected to the motor 5 and meshing with the first gear 624 , and a diameter of the second gear 7 is smaller than a diameter of the first gear 624 .

[0173] In this embodiment, the second gear 7 is connected to the motor 5. For example, the second gear 7 can be mounted on the shaft of the motor 5. The second gear 7 meshes with the first gear 624, so that when the motor 5 is operating, the second gear 7 can drive the first gear 624 to rotate, realizing a gear transmission and providing power for the rotation of the first gear 624. At the same time, the gear transmission can also effectively control the opening of the sewage outlet 22, preventing the sewage outlet 22 from being too wide and causing liquid splashing. The diameter of the second gear 7 is smaller than that of the first gear 624, thus forming a reduction gear set. The small gear drives the large gear to rotate, which can reduce the output speed of the motor 5. Therefore, when discharging sewage, the sewage outlet 22 can be slowly opened, thereby avoiding splashing during sewage discharge.

[0174] In some embodiments, as shown in FIG17 , the floor scrubber further includes a first rotating shaft 8 rotatably connected to the body 1 and / or the sewage tank 2 . The adjustment cover 3 is rotatably mounted on the body 1 and / or the sewage tank 2 via the first rotating shaft 8 .

[0175] In this embodiment, the adjustable cover 3 is rotatably mounted on the body 1 and / or the sewage tank 2 via the first rotating shaft 8, thereby enabling the adjustable cover 3 to be rotated open or closed relative to the sewage tank 2. Of course, in other designs, the adjustable cover 3 can also be configured as a sliding structure.

[0176] In some embodiments, as shown in FIG17 , the floor scrubbing device further includes an elastic element 9 connected to the adjustment cover 3 for returning the adjustment cover 3 to the third position after the adjustment cover 3 moves from the third position to the fourth position. When the adjustment cover 3 is in the third position, the drain outlet 22 is closed, and when the adjustment cover 3 is in the fourth position, the drain outlet 22 is open.

[0177] In this embodiment, the elastic element 9 can press the adjustable cover 3 when the adjustable cover 3 is in the third position to ensure that the adjustable cover 3 seals the sewage outlet 22. At the same time, the elastic element 9 is also used to return the adjustable cover 3 to the initial installation position after movement, so that the adjustable cover 3 can automatically return to its original position after the external force on the adjustable cover 3 disappears.

[0178] The elastic element 9 is a spring.

[0179] In some embodiments, as shown in FIG17 , the adjustment cover 3 includes: a covering portion 32 that can move relative to the drain outlet 22 to open or close the drain outlet 22; and a mating portion 34 that is used to cooperate with a driving assembly to drive the covering portion 32 to move relative to the drain outlet 22 under the drive of the driving assembly.

[0180] In this embodiment, the adjustable cover 3 is configured as a lever-type structure, wherein a covering portion 32 and a mating portion 34 are disposed at opposite ends of the first rotating shaft 8, forming the active and passive ends of the lever. When the driving device acts on the mating portion 34, the covering portion 32 opens the drain outlet 22. After the driving device and the mating portion 34 are separated, the adjustable cover 3 returns to the third position under the action of the elastic element 9.

[0181] In some embodiments, the adjustable cover 3 further includes a stopper configured to abut against the main body 1 and / or the sewage tank 2 when the adjustable cover 3 opens the sewage outlet 22 to a target opening size. The stopper is used to limit the opening angle of the adjustable cover 3, thereby limiting the opening degree of the sewage outlet 22. Specifically, when the adjustable cover 3 opens the sewage outlet 22 to the target opening size, that is, when the adjustable cover 3 opens to the target angle, the stopper abuts against the main body 1 and / or the sewage tank 2, preventing the sewage dry plate from opening further, thereby accurately limiting the opening angle of the adjustable cover 3.

[0182] Furthermore, the matching portion 34 and the covering portion 32 are located on both sides of the first rotating shaft 8 and form a lever structure.

[0183] In some embodiments, as shown in Figures 16 and 17, the sewage outlet 22 is provided at the bottom of the sewage tank 2. This arrangement allows the sewage outlet 22 to be provided relatively low, so that the sewage in the sewage tank 2 can be automatically discharged by its own gravity, thus eliminating the need for an additional sewage pump, thereby further simplifying the product structure.

[0184] As shown in Figure 25, an embodiment of the second aspect of the present application provides a base station 200 for controlling the operation of the floor scrubbing equipment of any embodiment of the first aspect, and the base station 200 includes: a floor brush mounting portion 210 for accommodating the floor brush assembly of the floor scrubbing equipment, and a drainage channel is provided on the floor brush mounting portion 210; when the floor scrubbing equipment is configured on the base station 200, the sewage inlet of the floor brush assembly 14 is connected to the drainage channel.

[0185] The base station 200 provided in the present application is used to control the operation of the floor scrubbing equipment. After the floor scrubbing equipment is finished working, it can automatically return to the base station 200 for charging, cleaning and other operations. Since the present application discharges sewage through the floor brush assembly 14, a drainage channel is provided on the floor brush mounting portion 210, and the drainage channel is connected to the sewer in the user's home. In this way, when it is necessary to discharge sewage, the adjustment cover 3 is directly opened, and the sewage in the sewage tank 2 can flow to the sewer channel along the sewage outlet 22, the sewage suction pipe 20 and the floor brush assembly 14, thereby realizing the automatic discharge of sewage in the sewage tank 2.

[0186] As shown in Figure 25, the base station 200 is also equipped with a second control device 220. The second control device 220 controls the adjustable cover 3 to open or close the drain outlet 22 according to the mode of the floor scrubber. The floor scrubber includes a sweeping mode, a draining mode, and a cleaning mode. In the sweeping mode, the adjustable cover 3 closes the drain outlet 22. In the draining mode, the adjustable cover 3 opens the drain outlet 22. In the sweeping mode, the adjustable cover 3 can open or close the drain outlet 22 as needed.

[0187] An embodiment of the third aspect of the present application provides a floor scrubbing assembly, comprising the floor scrubbing device of any embodiment of the first aspect; and the base station 200 of any embodiment of the second aspect.

[0188] In view of the fact that the floor scrubbing assembly provided in the present application includes the floor scrubbing device of any of the above embodiments and the base station 200 of any of the above embodiments, the floor scrubbing assembly has all the beneficial effects of the above floor scrubbing device and the above base station 200, which will not be described in detail here.

[0189] The floor scrubbing equipment in this application will be further introduced below with reference to Figures 14 to 23, taking a floor scrubber as an example.

[0190] As residents' living standards improve, people are increasingly pursuing an efficient and convenient cleaning experience. As an emerging and popular household cleaning appliance, the floor scrubber integrates sweeping, mopping and washing. There are two main ways to discharge sewage from related floor scrubbers: 1) The user manually removes the sewage tank and cleans it manually. 2) Through an independent external sewage pipe, it is discharged into the sewer through the base station. The manual cleaning method is cumbersome to operate, and the odor and visual impact of the sewage bring a lot of inconvenience to the user. The method of setting up an independent external sewage pipe makes the product structure complex, the product volume large, and the cost high. Therefore, there is an urgent need for a sewage discharge solution that can maintain the cleaning effect, is miniaturized and low-cost.

[0191] This application proposes a new sewage discharge system design, in which a sewage outlet 22 is set at the bottom of the sewage tank 2. The sewage outlet 22 is opened and closed by a driving mechanism located in the fuselage 1, and the sewage discharge channel is connected to the sewage suction pipe 20 to realize a 2-in-1 pipeline; while saving costs, the product remains compact and light.

[0192] The flow control principle of the present application is shown in Figures 14 and 15. The main unit has two usage states: sewage suction mode and sewage discharge mode. When the main unit is in sewage suction mode, the sewage flows along the first route L1, through the sewage suction pipe 20 and enters the sewage tank 2. When the main unit is in sewage discharge mode, the regulating cover 3 will be opened by the drive system, and the sewage in the sewage tank 2 will pass through the sewage outlet 22 and enter the sewage discharge cavity. The sewage discharge cavity and the sewage suction pipe 20 are connected, and the sewage flows along part of the sewage suction pipe 20 into the outlet of the floor brush end, and the sewage discharge is completed. Among them, when discharging sewage, the flow route of the sewage is shown as the second route L2 in Figure 15.

[0193] As shown in Figure 17, the opening and closing of the adjusting cover 3 are realized by the lever principle. The driving component moves upward, lifting the left part of the adjusting cover 3 (the left part of the first rotating shaft 8), and the adjusting cover 3 rotates clockwise around the first rotating shaft 8. The adjusting cover 3 opens and the sewage can flow out smoothly; the driving component moves downward, the opening force on the left side of the adjusting cover 3 is withdrawn, and the adjusting cover 3 is closed under the elastic force of the elastic element 9.

[0194] Among them, as shown in Figure 18, the working principle of the driving component is specifically as follows: after the driving component receives the electrical signal instruction, the motor 5 starts, driving the small gear (second gear 7) to start rotating, and the small gear (second gear 7) drives the large gear (first gear 624) to rotate counterclockwise (in the direction of the arrow in Figure 22), and the boss set on the large gear will rotate from the position shown in Figure 22 to the position shown in Figure 23. During the rotation, the boss drives the connecting rod 64 to move upward, and the connecting rod 64 finally pushes the adjusting cover 3 to rotate clockwise around the first rotating shaft 8, and the sewage outlet 22 opens; conversely, the motor 5 starts in reverse, drives the gear set and drives the boss to rotate clockwise from the position shown in Figure 23 to the position shown in Figure 22, and the boss drives the connecting rod 64 to move downward, and the sewage outlet 22 is closed.

[0195] In the above-mentioned floor scrubber, the sewage discharge pipe is connected to the sewage suction pipe, and the entire sewage discharge system is designed inside the original body 1 without any external flow path, which saves costs and does not affect the appearance.

[0196] In addition, in an alternative design, the driving mechanism can also be implemented by a cam mechanism, a rack and pinion mechanism, or a screw transmission mechanism.

[0197] In this specification, the terms "connect," "install," and "fix" should be understood broadly. For example, "connect" can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
