[0054] In a first aspect, this application provides a water storage system comprising:

[0055] The first water tank 100 has a cavity inside;

[0056] A partition wall 103 is connected to the cavity inside the first water tank 100. The partition wall 103 vertically divides the cavity into a first cavity 101 and a second cavity 102, which are independent of each other. The first cavity 101 is provided with an outlet 104 and the second cavity 102 is provided with an inlet 105.

[0057] The partition wall 103 is made entirely of flexible material or partially of flexible material. The partition wall 103 deforms in response to the pressure difference on both sides. The first cavity 101 and the second cavity 102 change their volume in response to the deformation of the partition wall 103.

[0058] The first upper cover 113 is movably connected to the first water tank 100. A sealing ring is provided at the movable connection between the first upper cover 113 and the first water tank 100. The first upper cover 113 and the first water tank 100 form a sealed cavity when connected.

[0059] The water tank isolation frame 106 divides the first water tank 100 vertically into a first cavity wall 107 and a second cavity wall 108. The outer edge of the water tank isolation frame 106 is connected to the first cavity wall 107, the second cavity wall 108 and the first top cover 113 respectively. The inner edge of the water tank isolation frame 106 is connected to the partition wall 103. The partition wall 103, the water tank isolation frame 106 and the first cavity wall 107 constitute a sealed first cavity 101. The partition wall 103, the water tank isolation frame 106, the second cavity wall 108 and the second top cover 202 constitute a sealed second cavity 102.

[0060] Specifically, refer to Figure 1 and Figure 2This application discloses a water storage system with interchangeable volumes. The cavity within the first water tank 100 is divided into a first cavity 101 and a second cavity 102 by a partition wall 103. The first cavity 101 and the second cavity 102 are independent of each other. Specifically, the first cavity 101 can be a clean water tank for storing clean water, which is discharged from the outlet 104 to clean the work surface. The second cavity 102 can be a wastewater tank for storing wastewater, which is used to collect wastewater generated after cleaning the floor. It is understood that as the water storage system operates, the clean water stored in the first cavity 101 flows out from the outlet 104 and is gradually consumed, thereby reducing the volume occupied by the clean water; at the same time, dirty water enters the second cavity 102 from the inlet 105, thereby increasing the volume occupied by the dirty water. Therefore, under the influence of the pressure difference caused by the volume change of the liquid in the two cavities, the partition wall 103, which is entirely or partially made of flexible material, will deform and be pushed towards the first cavity 101, reducing the size of the first cavity 101 and increasing the size of the second cavity 102. Similarly, when clean water is injected into the first cavity 101 or sewage is poured into the second cavity 102, the partition wall 103, which is entirely or partially made of flexible material, will deform and be pushed towards the second cavity 102, reducing the size of the second cavity 102 and increasing the size of the first cavity 101.

[0061] Reference Figure 2 In some specific embodiments, the first cavity 101 and the second cavity 102 are in a closed state during operation. At this time, combined with the above-mentioned liquid flow direction, along with the pressure change in the closed container, the partition wall 103 will respond more quickly to the volume change of the first cavity 101 and the second cavity 102, thereby adjusting the volume of the first cavity 101 and the second cavity 102 to a suitable volume more quickly.

[0062] In some preferred embodiments, the first water tank 100 is vertically divided into a first cavity 101 and a second cavity 102 by a partition wall 103. In this case, the partition wall 103 only bears the pressure of the liquid inside the first cavity 101 and the second cavity 102, which can better balance the internal volume of the first cavity 101 and the second cavity 102. At the same time, the first cavity 101 and the second cavity 102 can maintain nearly the same highest and lowest points in the vertical direction, which makes it easier for liquid to be discharged from the outlet 104 of the first cavity 101 and for liquid to be injected from the inlet 105 of the second cavity 102.

[0063] In some other embodiments, the partition wall 103 can divide the first water tank 100 into more chambers, such as a first chamber 101, a second chamber 102, and a third chamber. The first and second chambers 101 and 102 retain their original functions, while the third chamber can be additionally designed according to user needs and product applications, such as for collecting separated solid waste, filtering wastewater from the second chamber 102 to obtain clean water for re-injection into the first chamber 101, etc., without specific limitations. In this case, the partition wall 103, based on its material properties, can still balance the volume between the chambers, achieving optimal volume distribution within the water storage system.

[0064] Understandably, since the partition wall 103 can change its shape according to the pressure changes on both sides, it can be made of soft, hydrophobic materials such as silicone or soft rubber. Furthermore, the partition wall 103, which is made entirely or partially of flexible materials, can be a flexible material connected to a rigid outer frame to achieve a stable connection with the first water tank 100 while ensuring deformation and mutual volume change.

[0065] In some specific embodiments, the partition wall 103 is composed of a rigid partition and a flexible material.

[0066] Specifically, refer to Figures 2 to 4 The first upper cover 113 serves as a seal for the first water tank 100, and is movably connected to the upper opening of the first water tank 100 via a sealing ring. This ensures that when the first upper cover 113 is sealed to the first water tank 100, the first cavity 101 and the second cavity 102 remain sealed. On one hand, the sealed first cavity 101 and the second cavity 102 ensure that the clean water in the first cavity 101 and the wastewater in the second cavity 102 do not contaminate each other. On the other hand, the sealed first cavity 101 and the second cavity 102 can more efficiently provide the power for liquid transfer within the water storage system or improve the efficiency of deformation of the partition wall 103 in response to power components (such as gas pumps, liquid pumps, etc.) connected to the water storage system.

[0067] In some other embodiments, the first water tank 100 is divided by a partition wall 103 into a sealed first cavity 101 and a cavity with an open top. The cavity with the open top is sealed to the first top cover 113 to form a sealed second cavity 102. With the above arrangement, the water storage system provided in this application can ensure the independent storage of the liquid in the first cavity 101, avoiding contamination of the liquid in the first cavity 101 by other cavities or environmental contamination during the operation of the water storage system.

[0068] In some specific embodiments, the first upper cover 113 is provided with a movable connector. Through the movable connector, the water storage system provided in this application can achieve a movable connection between the first upper cover 113 and the first water tank 100. It is understood that, depending on the purpose of the movable connector, it can be a mechanical structure such as a snap-fit ​​or locking mechanism.

[0069] Specifically, refer to Figures 2 to 6 The water storage system also includes a water tank isolation frame 106, which vertically divides the first water tank 100 into two parts: a first cavity wall 107 and a second cavity wall 108. Furthermore, the water tank isolation frame 106 has an outer edge and an inner edge. The outer edge is directly connected to the first water tank 100, and the inner edge is directly connected to the partition wall 103. Through the connection between the water tank isolation frame 106, the first water tank 100, and the partition wall 103, the water tank isolation frame 106 effectively divides the first water tank 100 into two independent cavities: a first cavity 101 and a second cavity 102. Furthermore, the first water tank 100 forms a sealed cavity via a first upper cover 113, and this cavity is divided by the water tank isolation frame 106 into a sealed first cavity 101 and a sealed second cavity 102. By separately configuring the first cavity wall 107, the second cavity wall 108, and the partition wall 103, the assembly difficulty between the partition wall 103 and the first water tank 100 and the partition wall 103 in the water storage system is reduced. Furthermore, through the water tank isolation frame 106, the partition wall 103 can be selectively removed from the inside of the first water tank 100, thereby facilitating user cleaning of the inside of the first water tank 100. Simultaneously, the sealed first cavity 101 and second cavity 102 allow the partition wall 103 to more effectively respond to the liquid pressure on both sides and deform accordingly.

[0070] In some specific embodiments, the first cavity wall 107 and the second cavity wall 108 of the first water tank 100 are integrally formed. This integral forming further reduces the difficulty of assembling the partition wall 103 with the first water tank 100. In other embodiments, the first cavity wall 107 and the second cavity wall 108 of the first water tank 100 are movably connected, such as through mechanical means like snap-fit ​​connections. Through the movably connected first cavity wall 107 and second cavity wall 108, users can disassemble the corresponding cavity walls to clean the corresponding first cavity 101 or second cavity 102 according to their cleaning needs, thereby improving the user experience.

[0071] In some embodiments, the first upper cover 113 is provided with an injection port 105 and an exhaust port 115; wherein:

[0072] The water storage system also includes a liquid pipeline assembly 109, which is fixedly connected to the upper surface of the first cover 113 and connected to the second cavity 102 through an injection port 105.

[0073] The water storage system also includes an air duct 110, which is fixedly connected to the upper surface of the first cover 113 and extends into the interior of the second cavity 102 through an exhaust port 115.

[0074] Specifically, refer to Figure 2 and Figure 3 The first upper cover 113 is provided with an inlet 105 connecting to the external environment and the second cavity 102. The body of the liquid pipe assembly 109 is fixedly connected to the first upper cover 113, and one end of the liquid pipe assembly 109 extends into the second cavity 102 through the inlet 105, allowing sewage to flow into the second cavity 102 through the liquid pipe assembly 109. In some specific embodiments, the end face of the liquid pipe assembly 109 entering the second cavity 102 is at the same horizontal plane as the highest point of the second cavity 102, so as to improve the utilization rate of the volume of the second cavity 102. The first upper cover 113 is also provided with an exhaust port 115 that connects to the external environment and the second cavity 102. The pipe body of the air passage 110 is fixedly connected to the first upper cover 113, and one end extends into the interior of the second cavity 102. It can be understood that a negative pressure is generated in the air passage 110, so that the interior of the second cavity 102 is in a low-pressure state, thereby causing the liquid sewage to enter the second cavity 102 through the injection port 105 in response to the pressure change.

[0075] In some specific embodiments, the upper surface of the first cover 113 is provided with grooves adapted to the outer contours of the liquid conduit assembly 109 and the air passage 110. The liquid conduit assembly 109 and the air passage 110 are simultaneously fixed on the upper surface of the first cover 113, so that the gas passage and the liquid passage remain unobstructed.

[0076] In some specific embodiments, such as Figure 2 As shown, the liquid pipeline assembly 109 is fixedly disposed relative to the first upper cover 113, with the first upper cover 113 partially through it, allowing the liquid pipeline assembly 109 to pass through the first upper cover 113 and connect to the inlet 105. In some other embodiments, the liquid pipeline assembly 109 may also be part of the structure of the first upper cover 113, that is, the cavity formed by a portion of the shape of the first upper cover 113 serves to transport surface sewage by the liquid pipeline assembly 109, thereby reducing the assembly steps of the water storage system.

[0077] The liquid pipeline assembly 109 provided in this application is connected on one side to the injection port 105 of the second cavity 102 and on the other side to the sewage side of the ground, which can collect sewage from the ground into the second cavity 102 and realize the sewage recycling function of the water storage system relative to the cleaning equipment.

[0078] In some specific embodiments, such as Figure 2 As shown, the inlet 105 is located at the top of the second cavity 102 in the vertical direction, and the liquid pipeline assembly 109 is connected to the inlet 105 at the top in the vertical direction. Since the sewage on the ground may contain various solid wastes, dumping the wastes into the second cavity 102 from above can effectively prevent the wastes from accumulating inside the liquid pipeline assembly 109, thereby ensuring the smooth flow of the liquid pipeline assembly 109 and preventing blockages.

[0079] In some embodiments, the water tank isolation frame 106 has an air channel 114 at its top in the vertical direction, through which the first cavity 101 and the second cavity 102 exchange gases. Specifically, refer to... Figure 3 The first cavity 101 and the second cavity 102 are connected by an air channel 114, so that the gas pressure inside the first cavity 101 and the second cavity 102 is the same, thereby ensuring that the partition wall 103 is deformed by the liquid pressure on both sides, and avoiding the gas pressure on both sides of the partition wall 103 from affecting the deformation.

[0080] In some specific embodiments, the air passage 114 may be disposed on the surface of the first cover 113 relative to the first cavity 101 and the second cavity 102, and maintain unidirectional communication from the first cavity 101 to the second cavity 102.

[0081] In some specific embodiments, reference is made to Figure 3 A one-way valve 116 is installed on the air passage 114 on the water tank isolation frame 106. The one-way valve 116 covers the air passage 114, allowing the first chamber 101 to communicate with the second chamber 102. Since the second chamber 102 has an air duct 110, which is set to negative pressure, it is understood that the pressure inside the second chamber 102 should be lower than the pressure inside the first chamber 101. Gas flows from the first chamber 101 to the second chamber 102; therefore, the one-way valve 116 should ensure unobstructed flow from the first chamber 101 to the second chamber 102. The second chamber 102 contains wastewater, while the first chamber 101 contains clean water. To prevent wastewater in the second chamber 102 from contaminating the first chamber 101, the one-way valve 116 should ensure that the second chamber 102 remains closed to the first chamber 101.

[0082] In some embodiments, the inner edge of the water tank isolation frame 106 is sealed by overmolding and / or adhesive and / or mechanical structure.

[0083] The water tank isolation frame 106 and the partition wall 103 of the water storage system provided in this application are fixed by adhesive wrapping and / or mechanical structure and / or glue, thereby achieving mutual independence between the first cavity 101 and the second cavity 102.

[0084] In some embodiments, the partition wall 103 and the water tank isolation frame 106 are fixed by means of adhesive coating or glue. Using this method, the present application can effectively reduce the difficulty of connecting the partition wall 103 and the water tank isolation frame 106 to the first cavity wall 107 and the second cavity wall 108 of the first water tank 100. The non-movably connected partition wall 103 and water tank isolation frame 106 can also effectively reduce the risk of wear and tear or blockage by other foreign objects.

[0085] In some embodiments, the water storage system provided in this application further includes a drain valve assembly 112, which is disposed at the bottom of the first cavity 101 and covers the outlet 104.

[0086] Reference Figure 3 The drain valve assembly 112 covers the outlet 104, allowing the liquid in the first chamber 101 to flow out in a controlled manner. Specifically, when the water storage system provided in this application is installed on a floor scrubber, the drain valve assembly 112 can be opened according to the structure of the floor scrubber to allow the liquid in the first chamber 101 to be discharged from the outlet 104 into the first water tank 100; at the same time, when the water storage system is detached from the floor scrubber and is in an independent state, the drain valve assembly 112 can keep the bottom of the first chamber 101 sealed to prevent the liquid inside the first chamber 101 from spilling into the external environment.

[0087] In some embodiments, the first water tank 100 provided in this application is made of a rigid material, such that the total volume of the first cavity 101 and the second cavity 102 is fixed.

[0088] Reference Figure 2 and Figure 3 In some embodiments, the first water tank 100 is made of a rigid material, so that the total volume of the first cavity 101 and the second cavity 102 is fixed. Specifically, the first water tank 100 can be made of lightweight rigid materials such as plastic or hard materials. Such a first water tank 100 can ensure that the stored liquid remains stable on the one hand, and provide stable support for the partition wall 103 on the other hand, thereby realizing the mutual conversion of the volume between the first cavity 101 and the second cavity 102.

[0089] In some embodiments, the first cavity wall 107 of the water storage system provided in this application is provided with a water inlet 111, and the water tank system further includes a water inlet plug, which is movably connected to the water inlet 111, and the outer diameter of the water inlet plug is equal to the inner diameter of the water inlet 111.

[0090] Specifically, the first cavity wall 107 is provided with a water inlet 111, and the water storage system also includes a water inlet plug, which is movably connected to the water inlet 111, and the outer diameter of the water inlet plug is equal to the inner diameter of the water inlet 111. The water storage system of this application provides a first cavity 101 with at least one water inlet 111. In response to the liquid injection through the water inlet 111, the first cavity 101 expands its volume and reduces the volume of the second cavity 102. The water storage system also includes a water inlet plug, which is movably connected to the water inlet 111, and the outer diameter of the water inlet plug is equal to the inner diameter of the water inlet 111.

[0091] Through the water inlet 111 provided in this application, the user can inject liquid into the first cavity 101 to increase the volume of liquid in the first cavity 101, thereby changing the volume of the first cavity 101 relative to the second cavity 102; furthermore, through the movable water inlet plug, the liquid in the first cavity 101 can be effectively prevented from spilling, while maintaining the relatively sealed environment of the first cavity 101.

[0092] Understandably, in some specific embodiments, the water injection plug is movably connected to the first upper cover 113 to solve the problem of water injection plug storage. The water injection plug is preferably made of flexible materials such as silicone or soft rubber. In some special embodiments, the material of the water injection plug can be the same as that of the partition wall 103.

[0093] Secondly, referring to Figures 5 to 12 This application also discloses a floor scrubbing machine, comprising:

[0094] Such as the water storage system of the first aspect of this application; and,

[0095] The wastewater tank system includes a second water tank 200 and a second upper cover 202. The second upper cover 202 is movably connected to the upper part of the second water tank 200 in the vertical direction, forming a sealed cavity. The second upper cover 202 is provided with a suction duct, and the sealed cavity is connected to the air outside the wastewater tank system through the suction duct. The wastewater tank system also includes a solid-liquid separation device 203, the outer edge of which is movably connected to the sealed cavity. The solid-liquid separation device 203 divides the sealed cavity from top to bottom into a solid cavity 204 and a wastewater cavity 205 in the vertical direction. The solid cavity 204 is higher than the wastewater cavity 205 in the vertical direction. The wastewater tank system also includes a ground pipe 500, the first end of which extends into the sealed cavity through the solid-liquid separation device 203 and is fixedly installed in the solid cavity 204.

[0096] The first body 300, the water storage system and the sewage tank system are partially enclosed in the first body 300, and the first body 300 fixes the water storage system above the sewage tank in the vertical direction;

[0097] The cleaning head 400 is connected to the lower part of the first body 300 in the vertical direction via a pivot shaft. The cleaning head 400 fixes the second end of the ground pipe 500 to the near-ground side.

[0098] The first power assembly 310 is fixedly connected to the first fuselage 300 and is connected to the second cavity 102 through the air passage 110.

[0099] The second power assembly 410 is fixedly connected to the cleaning head 400 and connected to the first cavity 101;

[0100] The third power assembly 320 is fixedly connected to the first body 300 and is vertically connected to the suction duct of the sewage tank system.

[0101] Reference Figures 5 to 12The floor scrubber provided in this application includes a water storage system and a wastewater tank system. The second chamber 102 of the water storage system is liquidally connected to the second water tank 200 of the wastewater tank system via a liquid pipe assembly 109, allowing wastewater in the second water tank 200 of the wastewater tank system to flow into and be stored in the second chamber 102. The second water tank 200 of the wastewater tank system is also connected to the first end of a ground pipe 500, allowing wastewater from the working surface to flow into the second water tank 200 through the second end of the ground pipe 500. Furthermore, the floor scrubber also includes a first body 300, which partially encloses the water storage system and the wastewater tank system, allowing the water storage system to be fixedly installed above the wastewater tank system in the vertical direction. Furthermore, the floor scrubber also includes a cleaning head 400, which is pivotally connected to the lower part of the first body 300. Specifically, the pivot axis is parallel to the working surface of the floor scrubber and perpendicular to the direction of movement of the floor scrubber, allowing the first body 300 to accommodate the movement of the cleaning head 400 on the working surface and move freely relative to the cleaning head 400. The cleaning head 400 can also be connected to the first body 300 via a ball joint or other structure, achieving flexibility in the connection between the first body 300 and the cleaning head 400. Furthermore, the cleaning head 400 can also be fixedly connected to the second end of the ground pipe 500 of the second water tank 200, allowing the second end to be exposed near the ground, thus exposing the second end of the ground pipe 500 to the working surface of the floor scrubber for absorbing debris or wastewater on the working surface. The floor scrubber also includes a first power assembly 310, a second power assembly 410, and a third power assembly 320. Specifically, the first power assembly 310 and the third power assembly 320 are fixed inside the first body 300, and the second power assembly 410 is fixed inside the second body 401. The first power assembly 310 is connected to the second cavity 102 through the air duct 110, which draws out the gas inside the second cavity 102, thereby providing negative pressure to the second cavity 102, allowing the sewage in the second water tank 200 to enter the second cavity 102 through the liquid pipe assembly 109. The third power assembly 320 is connected vertically to the suction duct of the sewage tank system. Specifically, the third power assembly 320 generates negative pressure at its connection with the suction duct, and through its connection with the second water tank 200, it generates negative pressure in the second water tank 200. Simultaneously, it generates negative pressure in the ground pipe 500 connected to the second water tank 200, allowing the garbage or sewage at the second end of the ground pipe 500 to be sent into the second water tank 200. The second power assembly 410 is disposed inside and fixedly connected to the cleaning head 400, and connected to the first cavity 101, so that the liquid in the first cavity 101 is poured onto the cleaning head 400, thereby achieving the cleaning of the working surface by the cleaning head 400.The floor scrubber provided in this application can provide clean water to clean the working surface and collect wastewater into the second chamber 102. In response to changes in clean water and wastewater, the volumes of the first chamber 101 and the second chamber 102 change accordingly, thereby improving the liquid storage efficiency.

[0102] The wastewater tank system is equipped with a solid-liquid separation device 203, which is located inside the second water tank 200 of the wastewater tank system and connected to the cavity of the second water tank 200. The cavity of the second water tank 200 is vertically divided from top to bottom into a solid chamber 204 and a wastewater chamber 205. The solid separation device consists of a bottom filter plate and side walls. The first end of the ground pipe 500 is located in the solid chamber 204 above the bottom filter plate, drawing ground waste into the solid chamber 204 through the ground pipe 500. Wastewater from the ground waste is filtered through the bottom filter plate into the wastewater chamber 205. Furthermore, the wastewater chamber 205 is connected to the second chamber 102 via a liquid pipe assembly 109, allowing liquid wastewater to be transferred into the second chamber 102, thus achieving separate storage of solid waste and liquid wastewater. Specifically, the wastewater tank system is also equipped with a partition. This partition is positioned between the suction duct and the ground pipe, vertically surrounding or partially surrounding the first end of the ground pipe. The partition divides the solid chamber 204 into a first chamber and a second chamber. The first chamber is connected to the third power component 320, and the second chamber is connected to the ground pipe 500. The first and second chambers are partially connected, or connected through the wastewater chamber 205. This prevents mixed waste from being directly sucked into the suction duct from the ground pipe, contaminating the third power component 320, causing blockage, and reducing the cleaning capacity of the floor scrubber. The partition is positioned vertically above the highest point of the first end and vertically below the lowest point of the first end.

[0103] In one specific embodiment, refer to Figure 13 , Figure 13 This diagram illustrates the flow direction of gas and liquid inside the floor scrubber provided in this application. In response to the operation of the third power unit 320, the air pressure inside the second water tank 200 decreases, and debris from the work surface enters the second water tank 200 from the ground pipe 500 and remains there. Further, in response to the operation of the first power unit 310, the air pressure inside the second cavity 102 decreases, causing liquid in the second water tank 200 to transfer from the liquid pipe assembly 109 into the second cavity 102, thus collecting the debris generated after cleaning the work surface. Independent of the operation of the first power unit 310 and the third power unit 320, the second power unit 410 operates to pour the clean water stored in the first cavity 101 onto the cleaning head 400, enabling the floor scrubber to clean the floor. It is understood that the first power unit 310 can be a vacuum diaphragm pump, the second power unit 410 can be a peristaltic pump, and the third power unit 320 can be a suction motor.

[0104] In some embodiments, the second water tank 200 of the floor scrubber provided in this application further includes a wastewater drain valve 201, wherein: the wastewater drain valve 201 is located at the bottom of the wastewater chamber 205, and the wastewater drain valve 201 is connected to the liquid pipeline assembly 109 to transfer wastewater from the wastewater chamber 205 of the second water tank 200 to the second chamber 102.

[0105] Specifically, refer to Figure 11 and Figure 12 The floor scrubber provided in this application controls the discharge of wastewater from the second water tank 200 to the second cavity 102 of the first water tank 100 via a wastewater drain valve 201. The wastewater drain valve 201 located at the bottom of the second water tank 200 is connected to the second cavity 102 via a liquid pipe assembly 109. Under the action of the first power assembly 310, the wastewater is discharged from the wastewater drain valve 201 at the bottom of the second water tank 200 and finally collected into the second cavity 102 via the liquid pipe assembly 109, thus realizing the collection of wastewater from the ground. In some specific embodiments, the first body 300 has a protrusion relative to the position of the wastewater drain valve 201. When the second water tank 200 is installed on the first body 300, the protrusion opens the wastewater drain valve 201, so that the second cavity 102 is connected to the interior of the second water tank 200, realizing the flow of water. When the second water tank 200 is separated from the first body 300, the sewage drain valve 201 automatically rebounds, sealing the second water tank 200 and preventing liquid from spilling out of the second water tank 200.

[0106] In some embodiments, the first power assembly 310 of the floor scrubber provided in this application includes a vacuum diaphragm pump. The vacuum diaphragm pump is connected to the second chamber 102 of the first water tank 100. The vacuum diaphragm pump is connected to the second chamber 102 of the first water tank 100 through an air passage 110. By drawing air from the second chamber 102, a low-pressure environment is generated inside the second chamber 102, so that the liquid in the second water tank 200 is injected into the second chamber 102. Moreover, by directly drawing air from the vacuum diaphragm pump, it is possible to prevent debris from entering the pump body during the cleaning process and causing pump blockage, thereby improving the working stability of the floor scrubber.

[0107] In some embodiments, the second power component 410 of the floor scrubber provided in this application includes a peristaltic pump. Specifically, the peristaltic pump can draw liquid from the first chamber 101 of the first water tank 100, thereby enabling the floor scrubber to clean the floor using the drawn liquid as a medium.

[0108] In some specific embodiments, reference is made to Figures 5 to 12The floor scrubber also includes a second top cover 202, which is located at the upper part of the second water tank 200 in the vertical direction and is movably connected to the second water tank 200. Specifically, the second top cover 202 is movably connected to the upper part of the second water tank 200 in the vertical direction to cover the drain outlet of the second water tank 200. After removing the second top cover 202, the upward opening of the second water tank 200 can be used to dump the garbage inside the second water tank 200; when the second top cover 202 closes the opening of the second water tank 200, it can maintain a relatively closed environment of the second water tank 200. Furthermore, in some specific embodiments, the second upper cover 202 has a groove on the side opposite to the first water tank 100 in the length direction when the first water tank 100 and the second water tank 200 are connected. The groove is used to be movably connected to the third power component 320 and to provide support for the third power component 320 so that the third power component 320 creates a low-pressure environment for the second water tank 200. Specifically, a HEPA filter can be provided in the groove to provide a filtration function for the third power component 320.

[0109] In some embodiments, refer to Figures 5 to 12 The floor scrubber also includes a handle 600, which is parallel to the length of the first water tank 100 and the second water tank 200 when connected, and is fixed to the top of the first water tank 100 along its length. Specifically, the handle 600 is fixed along the length of the first water tank 100 and the second water tank 200 when connected, which in some specific embodiments is along the length of the first body 300, to facilitate the user to apply force and control the direction of movement of the floor scrubber.

[0110] In some embodiments, refer to Figures 5 to 12 The floor scrubber also includes an upper cover plate 301, which is pivotally connected to the first body 300. The upper cover plate 301 has a handle portion 302 and a cover body 303. The handle portion 302 is located at the upper part of the cover body 303 in the vertical direction, and the handle portion 302 is fixedly connected to the cover body 303. Specifically, refer to... Figure 7 The upper cover 301 is pivotally connected to the first body 300 via the first connector 307, allowing the upper cover 301 to be opened relative to the first body 300 via a pivot axis, revealing the first water tank 100 installed inside the first body 300. Furthermore, the upper cover 301 is provided with a handle 302 and a cover 303. The handle 302 facilitates the user in opening the upper cover 301, while the cover 303 is movably connected to the first body 300, achieving a stable connection between the floor scrubber and the upper cover 301.

[0111] In some specific embodiments, refer to Figure 5 as well as Figures 8 to 11The cover 303 is provided with a liquid pouring spout. The handle 302, movably connected to the cover 303, can simultaneously seal the liquid inside the second cavity 102 and, by separating from the cover 303, pour out the liquid from the second cavity 102. In some specific embodiments, an interactive panel is provided on the handle 302 in a top view. The configuration of the interactive panel in the figure is only a schematic diagram and can be modified according to the application scenario of the water storage system provided in this application.

[0112] In some embodiments, refer to Figures 5 to 12 The floor scrubber's cover 303 is equipped with a retaining ring 304. The retaining ring 304 is parallel to the length direction of the first water tank 100 and the second water tank 200 when they are connected. The handle 600 is fixed to the top of the first water tank 100 along its length direction via the retaining ring 304. Specifically, the outer diameter of the handle 600 is slightly larger than the inner diameter of the retaining ring 304. The retaining ring 304 can be made of plastic, hard rubber, or other materials with some flexibility. The handle 600 is inserted into the retaining ring 304 to achieve a parallel positional relationship along its length direction relative to the first water tank 100 and the second water tank 200 when they are connected.

[0113] In some specific embodiments, the top cover 301 is provided with a retaining ring 304, and the handle 600 is inserted into the retaining ring 304 in the longitudinal direction to fix it to the top of the first water tank 100 in the longitudinal direction. By using the handle 600 in the longitudinal direction provided when the first water tank 100 and the second water tank 200 are connected, the user can push / pull the floor scrubber to control the floor scrubber to clean the corresponding working surface.

[0114] In some embodiments, refer to Figure 8 The floor scrubber also includes a battery pack 305, which is housed within the first body 300 and vertically positioned at the connection point between the water storage system and the second water tank 200. The battery pack 305 is located in the middle of the first body 300 for easy electrical connection to various electrical components. Furthermore, its placement near the third power unit 320 facilitates power supply to the third power unit 320.

[0115] In some embodiments, refer to Figures 5 to 12 The cleaning head 400 includes:

[0116] The second fuselage 401 is located at the lower part of the first fuselage 300 in the vertical direction, and the second fuselage 401 is pivotally connected to the first fuselage 300;

[0117] The roller brush 402 is positioned in front of the second body 401 in the direction of movement. The roller brush 402 is used to absorb the liquid discharged from the second power assembly 410.

[0118] Roller 403 is located at the rear of the second body 401 in the direction of movement, and roller 403 is connected to the second body 401.

[0119] The cleaning head 400 of the floor scrubber provided in this application includes a second body 401, a roller brush 402, and rollers 403. The second body 401 functions similarly to the first body 300, fixing the relative positional relationship between the rollers 403, the roller brush 402, and the first body 300. Specifically, the second body 401 is located on the side of the first body 300 closer to the working plane, i.e., at the lower part of the first body 300 in the vertical direction, and is pivotally connected to the first body 300. This allows the first body 300 to rotate relative to the pivot axis connected to the second body 401 when the floor scrubber is working on the working plane. In some specific embodiments, the direction of the pivot axis is perpendicular to the plane formed by the vertical direction and the direction of movement of the floor scrubber. The direction of the pivot axis is also perpendicular to the plane formed by the direction of the handle 600 and the direction of movement of the floor scrubber in the use state, thereby adapting to the user's hand comfort at different working plane angles.

[0120] The roller brush 402 provided in this application is used for direct contact with the working surface. When the floor scrubber is in operation, it is connected to the second body 401 via a shaft at a forward position along the movement direction of the second body 401, enabling the roller brush 402 to roll relative to the working surface, thereby achieving cleaning of the working surface. Furthermore, the roller brush 402 is provided with bristles, which can be made of soft materials such as cotton and have a certain degree of water absorption, thereby improving the cleaning ability of the roller brush 402 on the working surface. The roller 403 provided in this application is used to directly contact the working surface. When the floor scrubber is in operation, it is connected to the second body 401 via a shaft at a rearward position along the movement direction of the second body 401. That is, it is set at a rearward position relative to the roller brush 402 in the movement direction, so as to realize the rolling of the roller 403 relative to the working surface, which helps the cleaning head 400 to move smoothly on the working surface. The axial direction of the roller 403 is set parallel to the axial direction of the roller brush 402 to ensure the stability of the relative positional relationship between the roller brush 402 and the roller 403 during the movement of the cleaning head 400.

[0121] In some embodiments, refer to Figures 5 to 12 The floor scrubbing machine provided in this application also includes:

[0122] Working head 700, and;

[0123] The throat 800 is connected at one end to the ground pipe 500 and at the other end to the working head 700. In response to the low-pressure environment generated in the second water tank 200 by the third power unit 320, the throat 800 sucks up the debris from the working surface from the working head 700 and collects it into the second water tank 200.

[0124] The floor scrubber provided in this application also includes a working head 700, which is interconnected with a hose 800. In some specific embodiments, the hose 800 can be a flexible tube to provide working performance in all directions for the working head 700. Specifically, the working head 700 is used to collect debris on the working surface and deliver it into the second water tank 200 through the hose 800 connected to it. Further, one side of the hose 800 is connected to the working head 700, and the other side is connected to the ground pipe 500. Due to the connection between the ground pipe 500 and the second water tank 200, the low-pressure environment created by the third power component 320 in the second water tank 200 simultaneously generates a low-pressure environment in the hose 800, allowing the debris collected by the working head 700 to be smoothly delivered into the second water tank 200 through the hose 800.

[0125] In some specific embodiments, the ground pipe 500 has a switching mechanism for controlling the switching state between the ground pipe 500 and the throat pipe 800. Specifically, the switching mechanism can be a tee fitting, with one end connected to the throat pipe 800 and the other two ends forming part of the pipe body of the ground pipe 500. The tee fitting has a first switching state and a second switching state. When the tee fitting is in the first switching state, the end of the ground pipe 500 relative to the working surface is closed, and the ground pipe 500 and the throat pipe 800 are in a connected state. When the tee fitting is in the second switching state, the end of the ground pipe 500 relative to the working surface is open, and the ground pipe 500 and the throat pipe 800 are in a disconnected state.

[0126] Furthermore, the second body 401 is provided with an opening for matching the switching mechanism of the ground pipe 500, through which the user can adjust the connection state of the switching mechanism.

[0127] In some embodiments, refer to Figures 5 to 12 The floor scrubbing machine provided in this application also includes:

[0128] A movable latch 306 is vertically mounted on the machine body and is used to secure the hose 800 and the working head 700. Preferably, the movable latch 306 provided in this application is mounted on the first machine body 300 along the length direction of the first water tank 100 and the second water tank 200 when connected, to secure the hose 800 and the working head. In some specific embodiments, multiple movable latches 306 are provided, and these multiple movable latches 306 are sequentially placed on the first machine body 300 along the length direction, with the total distance between the lines connecting each movable latch 306 being less than the length of the hose 800. The movable latch 306 provided in this application allows the working head 700 to be fixed on the first machine body 300 when not in operation, facilitating user placement of the floor scrubber or convenient use of the cleaning head 400 to clean the work surface.

[0129] In a complete embodiment, refer to Figures 1 to 12 The floor scrubber provided in this application comprises, from top to bottom, a handle, a water storage system provided in the first aspect, a first body, a wastewater tank system, and a cleaning head in the vertical direction, as well as a first power assembly, a second power assembly, and a third power assembly disposed within the first body and the cleaning head. A throat and a working head are also provided on one side of the body. The second water tank of the first water tank system is divided into a solid chamber and a wastewater chamber from top to bottom by a solid-liquid separation device. A partition is horizontally disposed between the suction duct and the ground pipe, and vertically surrounds or partially surrounds the first end of the ground pipe, thus dividing the solid chamber into a first chamber and a second chamber. The first chamber accommodates the suction duct formed by the second top cover, and the second chamber accommodates the first end of the ground pipe. The first water tank of the water storage system is vertically divided into a first chamber and a second chamber by a flexible partition wall. The first chamber is used to contain clean water, and the second chamber is used to contain wastewater. Specifically, the partition wall is connected to the first water tank via a water tank isolation frame. The partition wall is sealed to the water tank isolation frame using methods such as rubber coating to achieve relative independence between the first and second chambers. A one-way valve is installed on the water tank isolation frame, allowing gas to flow from the first chamber to the second chamber, thereby making the internal air pressure of the first and second chambers the same, while simultaneously preventing sewage from flowing from the second chamber into the first chamber.

[0130] The first and third power components are housed within the first body. The first power component is connected to the second chamber of the first water tank, providing the driving force for wastewater to flow into the second chamber. The third power component is connected to the suction duct of the second cover of the wastewater tank system, providing the driving force for mixed waste on the working surface to move into the second water tank. The second power component is located within the cleaning head, drawing clean water from the first chamber of the first water tank and discharging it onto the working surface. The second power component is positioned within the second body of the cleaning head, as close as possible to the roller brush, ensuring sufficient pressure for even spraying of the liquid onto the roller brush. The first and second water tanks are movably connected via the first body, allowing them to be removed independently of the first body. The first body has protrusions relative to the drain valve assembly of the first water tank and the wastewater drain valve of the second water tank, ensuring that the drain valve assembly and wastewater drain valve remain open when the first and second water tanks are installed on the first body, allowing the corresponding liquids to drain or flow in. The first water tank has a top cover that is movably connected via a first connector. The user can remove the top cover to fill the first chamber with clean water or empty the wastewater from the second chamber. The second water tank has a second top cover that is movably connected, allowing the user to remove the second top cover to separately empty the waste from the second water tank during the floor scrubber's operation. A detailed diagram of the air and water ducts can be found in [reference needed]. Figure 13The first power component can be a vacuum diaphragm pump, the second power component can be a suction motor, and the third power component can be a peristaltic pump.

[0131] Furthermore, a HEPA filter is installed at the connection between the third power unit and the second water tank to prevent foreign objects from entering the third power unit and causing equipment malfunction. A wastewater drain valve is installed on the bottom side wall of the second water tank, specifically on the side wall within the wastewater chamber. This wastewater drain valve is connected to the second chamber via a liquid pipeline assembly to transport wastewater to the second chamber under the action of the first power unit. The floor scrubber has an upper cover plate vertically above the first cover. The upper cover plate is pivotally connected to the first body, allowing it to flip relative to the first body, thereby exposing the first water tank, which is movably connected inside the first body, and enabling disassembly of the first water tank. The upper cover plate has a handle and a cover body. The cover body is movably connected to the first body, and the handle is fixedly connected to the cover body to allow for flipping the upper cover plate. An interactive panel is also provided on the upper cover plate, allowing users to quickly control the floor scrubber's operating status. The floor scrubber's handle is inserted into a retaining ring on the upper cover plate. The retaining ring is fixedly connected to the cover body or is part of the cover body. The battery pack is housed within the first body, in a cavity between the first and second water tanks, providing power to the floor scrubber. The floor scrubber also includes a second body and a roller brush and rollers mounted within it. The roller brush and rollers have parallel rolling axes and are fixed to the second body. The roller brush cleans the work surface and assists the floor scrubber's movement on the work surface. A second connecting member is provided on the second body, through which the second body is pivotally connected to the first body, with the pivot axis parallel to the axis of the roller brush or roller. Specifically, the roller brush axis, roller axis, and the pivot axis of the second body relative to the first body are parallel to and perpendicular to the plane formed by the floor scrubber's direction of movement and the vertical direction. Furthermore, the floor scrubber includes a working head and a hose. The working head, in addition to working on the floor, can handle other surfaces, such as walls, curtains, and sofas, cleaning debris. The working head connects to the hose, which connects to a floor pipe and shares the low-pressure environment generated by the third power unit with the second water tank, which is also connected to the floor pipe. The ground pipes connect to the second water tank and the cleaning head. Waste collected from the cleaning head via the third power unit is transported to the second water tank through these ground pipes. The ground pipes also include a T-junction; the two ends of the T-junction form part of the ground pipe network, while the remaining end connects to the hose reel. The T-junction can be set to a first connected state and a second connected state.
