Description

Technical Field

[0001] The utility model relates to the field of floor washing machines, and particularly relates to a noise-reducing cleaning device. Background Art

[0002] Environmental sanitation is an important factor affecting the quality of life. Therefore, with the continuous improvement of people's requirements for the quality of life, the corresponding requirements for environmental sanitation are also getting higher and higher. However, the work pressure of modern people is increasing day by day, and there is an urgent need to be liberated from the heavy cleaning work. So, many floor cleaning devices have emerged to improve environmental sanitation, such as floor washing machines.

[0003] In order to clean the floor, some existing floor washing machines will spray water on the floor synchronously while cleaning the floor through a cleaning member, so as to prevent excessive dust from being generated when the cleaning member cleans the floor. However, this method has a defect. For example, during cleaning, the washing machine itself needs to carry a liquid storage box. The liquid for spraying is stored in this box, and the liquid outlet of these liquids needs to be set above the cleaning member to wet the cleaning member.

[0004] However, the liquid in the box is not used up every time of cleaning. When the liquid is not used up and the washing machine needs to stop, once the washing machine is not used for a long time, the suspended matter mixed in the liquid in the box will accumulate at the bottom of the box due to long-term storage. In this way, if the liquid in the box is needed to clean the floor later, the accumulated suspended matter is likely to cause blockage of the pipeline and even form an odor. But if the floor washing machine directly sprays the liquid in the box on the cleaning member when it finishes working, the cleaning member itself will be prone to generate mildew due to dampness. On the other hand, the existing washing machines are noisy. Summary of the Utility Model

These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present utility model.

[0032] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, and in other embodiments, the number of this element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0033] Refer to Figures 1 to 6 , a cleaning device according to a preferred embodiment of the present utility model will be elaborated in detail below. The cleaning device includes a device body 10 and a cleaning assembly 20. The cleaning assembly 20 includes a cleaning member 21 and a driving motor 22, wherein the cleaning member 21 is drivingly connected to the driving motor 22. The cleaning assembly 20 is disposed at the bottom of the device body 10.

[0034] Preferably, the cleaning member 21 is implemented as a brush disc with bristles, and the cleaning member 21 is drivingly and rotatably connected to the driving motor 22 about the vertical direction. When the cleaning device is working, the cleaning member 21 can clean the ground.

[0035] Preferably, the cleaning component 20 further comprises a liquid supply member 23 and a transferable drainage component 24. The liquid supply member 23 comprises a liquid supply box 231 and a set of liquid guide tubes, wherein the transferable drainage component 24 comprises at least one three-way valve 241, wherein a first opening of the three-way valve 241 is connected to the liquid supply box 231 through one of the liquid guide tubes. A second opening of the three-way valve 241 is connected to another of the liquid guide tubes, and the other end of the liquid guide tube is kept above the cleaning member 21. In addition, a third opening of the three-way valve 231 is extended to deviate from the cleaning member 21 and is kept facing the ground.

[0036] Those skilled in the art can understand that, through such a configuration, when the three-way valve 241 is operated to connect the first opening and the second opening, the cleaning assembly 20 can clean the floor through the cleaning member 21 while spraying the cleaning liquid in the liquid supply tank 231 onto the cleaning member 21. In this way, the cleaning member 21 will not generate excessive dust when cleaning the floor.

[0037] When cleaning is completed, the valve core of the three-way valve 241 can be operated to connect the first opening with the third opening, and the cleaning liquid in the liquid supply box 231 can be discharged through the third opening. It is worth mentioning that since the third opening is set to deviate from the cleaning member 21, the third opening does not overlap with the cleaning member 21 in height, that is, it is staggered in position with the cleaning member 21. In this way, the liquid in the liquid supply box 231 can be completely drained, and excessive liquid can be prevented from flowing to the cleaning member 21 when draining.

[0038] Furthermore, the cleaning component 20 also includes a suction member 30, the suction member 30 includes a liquid suction member 31 and a liquid suction power element 32, the liquid suction member 31 forms at least one liquid suction port 3101 and a liquid suction cavity 3102 whose one end is connected to the liquid suction port 3101 and a liquid outlet connected to the liquid suction cavity, wherein the liquid suction power element 32 is arranged to be connected to the liquid suction cavity 3102, and is used to guide the dirty liquid from the liquid suction port 3101 to the other end of the liquid suction cavity 3102.

[0039] Specifically, the liquid suction port 3101 is arranged and maintained at the bottom of the device body 10 .

[0040] Preferably, the length of the liquid suction port 3101 formed by the liquid suction member 31 extending in the horizontal direction is not less than the width of the cleaning member 21 extending in the horizontal direction. In addition, the liquid suction port 3101 is located behind the cleaning member 21 .

[0041] Those skilled in the art can understand that in this way, after the cleaning member 21 completes cleaning, the liquid absorption member 31 can absorb the liquid on the area cleaned by the cleaning member 21, especially the area sprayed with cleaning liquid and then cleaned. In this way, the cleaning device can not only clean the ground, but also absorb the liquid remaining on the ground and the ground itself.

[0042] In one embodiment, the liquid absorption member 31 is slidably and detachably mounted on the cleaning member 21 in the horizontal direction. Specifically, in one embodiment, the suction member 30 includes a mounting plate 33, and the liquid absorption member 31 is mounted on the mounting plate 33. The mounting plate 33 is slidably and detachably mounted on the cleaning member 21 in the transverse direction.

[0043] Specifically, a pair of front and rear spaced chutes 211 are formed in the rear part of the cleaning member 21 along the horizontal width direction. At least a pair of sliding feet 331 are provided on the mounting plate 33, and the mounting plate 33 is slidably clamped on a pair of the chutes 211 through the sliding feet 331.

[0044] At least one end of at least one side of the part where the chute 211 is formed at the bottom of the cleaning member 21 is provided with a fixing hole 212. At least one side of the mounting plate 33 corresponding to the fixing hole 212 is formed with a pair of alignment holes 332. When the liquid absorption member 31 is correspondingly clamped on the chute 211 through the sliding feet 331 and the liquid absorption member 31 is pushed in place, the alignment holes 332 on the mounting plate 33 will be aligned with the fixing hole 212. The suction member 30 includes at least one fixing screw 34. After the fixing screw 34 is screwed into the fixing hole 212 and the alignment hole 332, the liquid absorption member 31 can be more stably fixed at the bottom of the cleaning member 21.

[0045] It is worth mentioning that when it is necessary to disassemble the liquid absorption member 31, only the fixing screw 34 needs to be removed, and then, by pulling the mounting plate 33 transversely, the disassembly of the entire liquid absorption member 31 can be achieved.

[0046] Preferably, the suction member 30 includes at least one floating element 35, and the floating element 35 is disposed between the mounting plate 33 and the liquid absorption member 31.

[0047] Specifically, the floating element 35 includes at least one elastic member 351, and both ends of the elastic member 351 are respectively pressed between the mounting plate 33 and the liquid absorption member 31 to press the liquid absorption port 3101 of the liquid absorption member 31 against the ground, so that the liquid absorption cavity 3102 forms a closed space to facilitate the subsequent absorption of the liquid in the liquid absorption cavity 3102.

[0048] Preferably, the floating element 35 further includes at least one guide rod 352, wherein the elastic member 351 is sleeved on the guide rod 352, and both ends are pressed between the mounting plate 33 and the liquid absorbing member 31. In addition, at least one of the mounting plate 33 and the liquid absorbing member 31 is slidably limited to the guide rod 352. Preferably, the mounting plate 33 and the liquid absorbing member 31 are respectively limited to both ends of the guide rod 352 to prevent the mounting plate 33 and the liquid absorbing member 31 from separating from the guide rod 352.

[0049] Preferably, the suction member 30 includes two of the floating elements 35, and the two floating elements 35 are spaced apart between the mounting plate 33 and the liquid absorbing member 31.

[0050] The machine body further includes an attitude adjustment assembly 40, and the attitude adjustment assembly 40 is mounted on the equipment body 10, wherein the cleaning assembly 20 is connected to the attitude adjustment assembly 40 in a vertically movable manner.

[0052] In one embodiment, the cleaning assembly 20 is connected to the driving lifting member 41 in a vertically liftable manner.

[0053] One lifting end of the driving lifting member 41 is connected to the cleaning member 21, so that when the lifting end of the driving lifting member 41 lifts and lowers, the entire cleaning assembly 20 can be driven by the driving lifting member 41 to lift and lower vertically.

[0054] Those skilled in the art can understand that in this way, when it is necessary to clean the ground through the cleaning assembly 20, the cleaning assembly 20 can be driven to sink and contact the ground, and then the driving motor 22 can be started, so that the cleaning member 21 can be made to adhere to the ground to clean the ground. On the contrary, when the cleaning is completed, the cleaning assembly 20 can be driven to rise and lift off the ground, so that the cleaning member 21 can be prevented from contacting the ground and being damaged due to excessive friction with the ground when the dual-mode cleaning device is in a non-working state.

[0055] In a preferred embodiment, the driving and lifting member 41 includes a driving unit 411 and a connecting chain 412. The driving unit 411 has a telescopic end 41101.

Both the connecting chain 412 and the driving unit 411 are installed on the device body 10. As the driving unit 411 is driven, the telescopic end 41101 telescopically moves accordingly, thereby driving the cleaning member 21 to rise or fall along the vertical direction.

[0056] In one embodiment, the telescopic end 41101 is implemented as a lifting end. That is to say, the connecting chain 412 will be driven by the telescopic end 41101 of the driving unit 411 to move up and down, and further drive the cleaning assembly 20 to move up and down.

[0057] In a variant embodiment, the telescopic end 41101 is implemented as a mobile end that can move substantially along the horizontal direction. In this embodiment, the driving and lifting member 41 further includes an orientation adjusting element 413. The orientation adjusting element 413 forms an orientation adjusting channel 41301 for accommodating the connecting chain 412. After one end of the connecting chain 412 is connected to the telescopic end 41101, it gradually extends a predetermined distance along the substantially horizontal direction, and then passes through the orientation adjusting channel 41301 of the orientation adjusting element 413, and then gradually extends along the substantially vertical direction, and the other end is connected to the cleaning member 21. In this way, as the telescopic end 41101 of the driving unit 411 telescopically moves, the cleaning assembly 20 can be moved up and down.

[0058] In one embodiment, the orientation adjusting element 413 is provided to include a pair of sector plates 4131 and a guiding block 4132 installed between the pair of sector plates 4131. The sector edges of the pair of sector plates 4131 extend in the plane direction of the sector and protrude outward to form the orientation adjusting channel 41301 between the sector edge of the sector plate 4131 and the top surface of the sector area of the guiding block 4132.

[0059] In a preferred embodiment, the attitude adjusting assembly 40 further includes a link member 42. The link member 42 includes at least one link. One end of each link is rotatably connected to the cleaning member 21, and the other end is rotatably connected to the device body 10.

[0060] In this way, when the driving unit 411 of the driving and lifting member 41 drives the cleaning assembly 20 to move up and down, by means of the link member 42, it is possible to effectively prevent the cleaning assembly 20 from shaking during the up and down movement.

[0061] Further, the cleaning device further includes a traveling assembly 50, and each traveling assembly 50 is implemented to include at least a pair of rollers 51, wherein the rollers are mounted on the bottom of the device body 10.
