In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Please see Figures 1-3 The first aspect of this utility model provides a floor scrubbing machine, which includes a main body 100 and a brushing mechanism 200. The main body 100 is mainly used to provide the user with a control and gripping part, and the brushing mechanism 200 is mainly used for cleaning work.

[0024] The main body 100 includes a first housing 110, a negative pressure component 120, and a first liquid chamber 130. A first receiving cavity 111 is formed inside the first housing 110. The negative pressure component 120 is disposed inside the first receiving cavity 111. The first liquid chamber 130 is detachably connected to the first housing 110 and is used to store the target liquid. The first liquid chamber 130 is provided with a drain valve 140.

[0025] The drain valve 140 has a switchable first state and a second state. In the first state, the first liquid chamber 130 can store the target liquid. In the second state, the first liquid chamber 130 can discharge at least part of the target liquid through the drain valve 140. The negative pressure component 120 is connected to the first liquid chamber 130 and is used to provide negative pressure so that the first liquid chamber 130 can draw in the target liquid through negative pressure. It is understood that the target liquid can be sewage generated during the cleaning process, sewage present in the cleaning environment, or clean water, etc.

[0026] The floor brushing mechanism 200 includes a second housing 210, a roller brush assembly 220, a second liquid tank 230, and a water suction pipe 240. The first housing 110 is rotatably connected to the second housing 210, the roller brush assembly 220 is rotatably connected to one side of the second housing 210, and the second liquid tank 230 is detachably connected to the second housing 210. The second liquid tank 230 is at least used to store cleaning fluid and to deliver cleaning fluid to the roller brush assembly 220. The water suction pipe 240 forms a water suction port 241 and is connected to the first liquid tank 130 so that the target liquid can flow to the first liquid tank 130 through the water suction port 241. It is understood that the cleaning fluid can be clean water or cleaning reagents, etc.

[0027] The floor scrubber has at least two working modes. In the first working mode, the drain valve 140 switches to the first state, the negative pressure component 120 works and performs a water suction operation through the suction port 241 to suck the target liquid into the first liquid tank 130. It can be understood that the first working mode of the floor scrubber is mainly used for cleaning. During use, the second liquid tank 230 provides cleaning fluid to the roller brush component 220 so that the roller brush component 220 can clean. The negative pressure component 120 provides a vacuum negative pressure to suck the wastewater generated during the cleaning process from the suction port 241 and store it in the first liquid tank 130.

[0028] In the second working mode, the drain valve 140 switches to the second state so that the target liquid in the first liquid chamber 130 is discharged from the drain valve 140. After the first liquid chamber 130 completes the drainage operation, the negative pressure component 120 is activated. During the operation of the negative pressure component 120, the cleaning fluid enters the first liquid chamber 130 through the suction pipe 240, and air enters the first liquid chamber 130 through the drain valve 140 and agitates the cleaning fluid in the first liquid chamber 130 so that the cleaning fluid in the first liquid chamber 130 flushes the inner wall of the first liquid chamber 130.

[0029] It is understandable that after the first liquid tank 130 completes the draining operation, some sewage residue will remain on the inner wall of the first liquid tank 130, making it difficult to clean the dirt stuck on the inner wall of the first liquid tank 130. However, in the floor scrubber provided in this embodiment, the drain valve 140 is open during the cleaning process, and negative pressure is provided by the negative pressure component 120 so that cleaning liquid can be drawn into the suction port 241. Gas enters the first liquid tank 130 from the drain valve 140. As the gas disturbs the cleaning liquid, the liquid moves irregularly in the first cleaning tank, similar to the state of liquid boiling, so that the cleaning liquid can thoroughly clean the inner wall of the first liquid tank 130. Compared with most floor scrubbers that require the first liquid tank 130 to be disassembled for manual cleaning, the floor scrubber of this application is more convenient for cleaning and maintenance.

[0030] like Figure 3As shown, in some embodiments, a water delivery pipe 131 is formed inside the first liquid tank 130. One end of the water delivery pipe 131 is connected to the water suction pipe 240, and the other end of the water delivery pipe 131 is spaced apart from the drain valve 140 in the extending direction of the water delivery pipe 131. Through the connection between the water delivery pipe 131 and the water suction pipe 240, in the second working mode of the floor scrubber, the cleaning fluid enters the water delivery pipe 131 and falls into the first liquid tank 130. Because the water delivery pipe 131 and the drain valve 140 are spaced apart, the cleaning fluid, after entering the first liquid tank 130, will fall towards the drain valve 140 due to gravity. Simultaneously, gas enters the first liquid tank 130 from the drain valve 140. The cleaning fluid and gas in the first liquid tank 130 collide, causing disturbance in the liquid within the first liquid tank 130 and increasing the degree of gas disturbance to the cleaning fluid, thereby effectively cleaning the inner wall of the first liquid tank 130.

[0031] Please see Figure 4 The first liquid tank 130 has a drain port 141. The drain valve 140 includes a cover plate 142 and a first elastic member 144. The cover plate 142 is rotatably connected to the first liquid tank 130. One end of the cover plate 142 has a sealing plug 143 for closing the drain port 141. The first elastic member 144 abuts between the cover plate 142 and the first liquid tank 130, and the first elastic member 144 is located on the side of the cover plate 142 away from the sealing plug 143. The first liquid tank 130 can discharge the target liquid stored in the first liquid tank 130 through the drain port 141.

[0032] In the first state, the first elastic element 144 of the drain valve 140 is in the released state. The first elastic element 144 abuts between the first liquid tank 130 and the cover plate 142 and applies force to the cover plate 142, so that the side of the cover plate 142 with the sealing plug 143 abuts against the drain port 141, thereby inserting the sealing plug 143 into the drain port 141 and sealing the drain port 141, so that the first liquid tank 130 can store the target liquid.

[0033] In the second state, the drain valve 140 is subjected to force on one side of the cover plate 142 where the first elastic element 144 is provided, causing the first elastic element 144 to be in a compressed state. The cover plate 142 rotates under force, thereby causing the sealing plug 143 to disengage from the drain port 141, so that the target liquid in the first liquid chamber 130 is discharged from the first liquid chamber 130. After the force applied to the cover plate 142 is released, the first elastic element 144 returns to its original state, thereby resetting the cover plate 142, so that the drain valve 140 can automatically switch to the first state.

[0034] In some embodiments, the main body 100 is provided with a communication component 150, which is detachably connected to the first liquid chamber 130 and the first housing 110, respectively, and the negative pressure component 120 is connected to the first liquid chamber 130 through the communication component 150.

[0035] The connecting component 150 includes at least a water level detector 152 and a shielding component 151. The water level detector 152 and the shielding component 151 are disposed within the first liquid tank 130, with the shielding component 151 located between the water level detector 152 and the water supply pipe 131. The shielding component 151 is specifically a plate-shaped structure. The water level detector 152 is used to detect the amount of target liquid in the first liquid tank 130, preventing backflow of excessive target liquid from the water supply pipe 131 and causing wastewater to overflow from the floor cleaning mechanism 200. The shielding component 151 prevents the target liquid entering the first liquid tank 130 from directly impacting the water level detector, and also facilitates the concentrated falling of the cleaning fluid after entering the first liquid tank 130, so as to better counteract the gas entering the first liquid tank 130 and clean the inner wall of the first liquid tank 130.

[0036] Please see Figure 5 , Figure 6 In some embodiments, the floor brushing mechanism 200 further includes a power component housed within a second housing 210. The second housing 210 has multiple water outlets 250 near the roller brush assembly 220. These water outlets 250 communicate with a second liquid tank 230 via the second housing 210, and the power component guides the cleaning fluid stored in the second liquid tank 230 to the water outlets 250. In specific applications, the power component can be a water pump. The second housing 210 has a passage connected to the water pump, with one end connected to the second liquid tank 230 and the other end connected to the water outlets 250. This allows the water pump to provide power to guide the cleaning fluid stored in the second liquid tank 230 to the water outlets 250, continuously supplying cleaning fluid to the roller brush assembly 220 during cleaning. A suction port 241 is spaced apart from the multiple water outlets 250, allowing cleaning fluid or wastewater generated during cleaning to be sucked in through the suction port 241, thus preventing excessive liquid residue on the ground.

[0037] The roller brush assembly 220 and the second liquid tank 230 are spaced apart on opposite sides of the second housing 210. Multiple water outlets 250 are formed on the second housing 210 near the roller brush assembly 220 so that the cleaning fluid flowing out from the water outlets 250 can be directly supplied to the roller brush assembly 220 to improve the cleaning ability of the roller brush assembly 220.

[0038] like Figure 6As shown, in some embodiments, the brushing mechanism 200 further includes a cleaning component 280. The cleaning component 280 is detachably connected to the second housing 210 near the roller brush assembly 220, and is located between the roller brush assembly 220 and the second housing 210. A toothed plate 282 is formed on one side of the cleaning component 280, and an arc-shaped plate 281 is formed on the other side of the cleaning component 280 away from the toothed plate 282. The cleaning component 280 is located between the second housing 210 and the roller brush assembly 220, and the arc-shaped plate 281 at least covers a portion of the roller brush assembly 220 to prevent liquid splashing when the roller brush assembly 220 rotates. The toothed plate 282 is used to clean debris adhering to the roller brush assembly 220 during rotation, preventing debris from adhering to the roller brush assembly 220 and affecting its cleaning effect. Multiple water outlets 250 may also be formed on the surface of the cleaning component 280.

[0039] Please see Figure 7 In some embodiments, a water inlet 271 is formed on the second liquid tank 230, an annular limiting member 277 is formed inside the water inlet 271, and a water inlet valve 270 is provided at the water inlet 271. The water inlet valve 270 includes a valve member 272 and a second elastic member 276.

[0040] The valve 272 is disposed inside the water inlet 271. The valve 272 includes a rod body 275 and a first end 273 and a second end 274 located at both ends of the rod body 275. The second end 274 is located inside the second liquid tank 230 of the cleaning fluid. The radial dimension of the first end 273 and the second end 274 is larger than the inner diameter of the limiting member 277. The radial dimension of the rod body 275 is smaller than the inner diameter of the limiting member 277. The radial dimension of the first end 273 is smaller than the diameter of the water inlet 271. The second elastic member 276 is disposed inside the water inlet 271 and abuts against the first end 273 and the limiting member 277. With the water injection valve 270, the second elastic element 276 abuts against the first end 273 and the limiting element 277, causing the second end 274 to abut against the limiting element 277, thereby closing the water injection port 271 to prevent the cleaning fluid in the second liquid tank 230 from overflowing through the water injection port 271. During the process of injecting water into the second liquid tank 230, by abutting the water injection device against the first end 273, the first end 273 is forced to compress the second elastic element 276, causing the second end 274 to move away from the limiting element 277, thus opening the water injection port 271 and allowing the cleaning fluid to enter the second liquid tank 230 through the water injection port 271. When the water injection device disengages from the first end 273, the second elastic element 276 is released from force to push the first end 273, thereby causing the second end 274 to return to abutting against the limiting element 277, thus closing the water injection port 271. This improves the convenience of replenishing the second liquid tank 230 with cleaning fluid or clean water.

[0041] A floor scrubbing system provided in the second aspect of this utility model includes a floor scrubbing machine and a base station. It is understood that the floor scrubbing machine is the same as that in the first aspect of this application, and will not be described again here. The base station is provided with a placement position and forms a cleaning tank. When the floor scrubbing machine is placed in the placement position, the brushing mechanism 200 of the floor scrubbing machine is at least partially accommodated in the cleaning tank. The cleaning tank can be used to store clean water for cleaning the roller brush assembly 220 and the first liquid tank 130.

[0042] In summary, the floor scrubber provided in this embodiment provides negative pressure to the first liquid tank 130 through the negative pressure component 120 in the second working mode, so that the cleaning fluid enters the first liquid tank 130 from the suction port 241 and the gas enters the first liquid tank 130 from the drain valve 140. The cleaning fluid and the gas collide and disturb each other in the first liquid tank 130, causing the cleaning fluid to move irregularly in the first liquid tank 130, such as a liquid boiling effect. This allows the cleaning fluid to thoroughly clean the inner wall of the first liquid tank 130, thereby improving the convenience of cleaning and maintenance of the first liquid tank 130.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
