Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a cleaning device. Background Art

[0002] As a commonly used household appliance, the vacuum cleaner has been favored by more and more families in recent years.

[0068] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] As Figures 1 to 7 shown, in this embodiment, a cleaning device is provided, which includes a housing 1, a cleaning structure 2, and a driving structure 4. The cleaning structure 2 is arranged inside the housing 1 and has two cleaning members 21. The cleaning member 21 has a first state of approaching and hitting the object to be cleaned, and a second state of moving away from the object to be cleaned; the driving structure 4 is connected to the cleaning member 21 and is adapted to drive the cleaning member 21 to approach or move away from the object to be cleaned. The two cleaning members 21 alternately hit the object to be cleaned.

[0070] The cleaning device can be used to clean a rag or other object to be cleaned. The cleaning member 21 of the cleaning structure 2 cleans the rag or other object to be cleaned by hitting, imitating the cleaning principle of a wooden club hitting clothes, and cleaning the object to be cleaned thoroughly. Moreover, the friction between the cleaning member 21 and the rag is small, the wear of the rag and the cleaning member 21 itself is less, the service life of the rag and the cleaning member 21 is prolonged, and a stable cleaning effect of the cleaning member 21 is ensured. The cleaning device is also provided with a housing 1 to prevent the splashing of dirty water or dust during the cleaning process.

[0071] As a transformable embodiment, it may also be that the cleaning structure 2 has one cleaning member 21, or three cleaning members 21, or not less than three cleaning members 21 in other embodiments.

[0072] In this embodiment, the cleaning structure 2 includes a main body 22 and a mounting structure 23. The main body 22 is connected to the driving structure 4 and is adapted to rotate under the drive of the driving structure 4. The mounting structure 23 is connected to both sides of the main body 22, and the cleaning member 21 is disposed on the mounting structure 23. Two cleaning members 21 are connected to both sides of the main body 22 through the mounting structure 23. The mounting structure 23 rotates around the main body 22 driven by the main body 22, and the cleaning member 21 disposed on the mounting structure 23 realizes periodic impact on the object to be cleaned during the rotation process.

[0073] As a transformable embodiment, it may also be that the mounting structure 23 is connected to both sides of the main body 22, or connected to three sides of the main body 22, or connected to more sides of the main body 22 in other embodiments.

[0074] In this embodiment, the main body 22 includes a first rotating shaft 221 and two connecting rods 222. One end of the first rotating shaft 221 is connected to the driving structure 4. One end of the connecting rod 222 is connected to the first rotating shaft 221, and the other end is connected to the mounting structure 23. The two connecting rods 222 are disposed at both ends of the first rotating shaft 221 and are respectively connected to both ends of the mounting structure 23, and the connection is more stable.

[0075] As a transformable embodiment, it may also be that the main body 22 includes one connecting rod 222 or three connecting rods 222 or more connecting rods 222.

[0076] In this embodiment, the mounting structure 23 includes two second rotating shafts 231. The two second rotating shafts 231 are respectively located on both sides of the main body 22. There are two cleaning members 21, and one cleaning member 21 is respectively disposed on each of the two second rotating shafts 231.

[0077] As a transformable embodiment, it may also be that the mounting structure 23 includes one second rotating shaft 231. One second rotating shaft 231 is located on one side of the main body 22. One cleaning member 21 is disposed on the second rotating shaft 231. It may also be that the mounting structure 23 includes three or more second rotating shafts 231. The three or more second rotating shafts 231 are located on the side of the main body 22. One cleaning member 21 is disposed on each of the second rotating shafts 231. Preferably, the second rotating shafts 231 are evenly distributed along the circumferential direction of the first rotating shaft 221.

[0078] In this embodiment, the cleaning member 21 includes a roller 211 sleeved outside the second rotating shaft 231. The roller 211 can rotate around the second rotating shaft 231, reducing the friction with the object to be cleaned and decreasing the wear of both the roller 211 and the object to be cleaned.

[0079] In this embodiment, the inner diameter of the shaft hole of the roller 211 is larger than the outer diameter of the second rotating shaft 231. The roller 211 rotates centrifugally, and there is space for the roller 211 to move away from the object to be cleaned after hitting it, further reducing the frictional force and further decreasing the wear of both the roller 211 and the object to be cleaned.

[0080] In this embodiment, the cleaning member 21 further includes a plurality of smooth protrusions 212 provided on the outer peripheral wall of the roller 211. This enhances the impact effect. Also, due to the smooth protrusions 212, the increased frictional force is limited. Without wearing the roller 211 and the object to be cleaned, the cleaning effect is enhanced. Moreover, by providing the smooth protrusions 212, when there is wear, the smooth protrusions 212 are worn first, which does not affect the overall cleaning effect of the roller 211 and enhances the service life of the roller 211 to a certain extent.

[0081] In this embodiment, the cleaning device further includes a cleaning tank 3 provided below the cleaning structure 2. When the cleaning member 21 is in the second state, at least a part of it extends into the cleaning tank 3. Clear water or a washing liquid with detergent / washing powder can be loaded into the cleaning tank 3. When the cleaning member 21 is in the second state, at least a part of it extends into the cleaning tank 3 and is wetted by the washing liquid or clear water. When in the first state, the wetted cleaning member 21 realizes the cleaning of the object to be cleaned, enhancing the cleaning effect.
