[0039] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0040] The cleaning device described in the utility model can be a sweeping robot, a handheld floor scrubber, a window cleaning robot, etc.

[0041] Reference below Figure 1-Figure 7 The cleaning device 100 according to the embodiment of the utility model is described, which can selectively drive the cleaning component 20 to translate and rise as a whole according to different working environments, so that the cleaning component 20 can adapt to the current working environment, thereby improving the cleaning efficiency of the cleaning device 100.

[0042] Combination Figure 1-Figure 7 As shown, the cleaning device 100 according to the first embodiment of the utility model includes a body 10, a cleaning assembly 20 and a lifting mechanism 30. The body 10 is mainly used as a structural member for the inner and outer contours of the cleaning device 100. The cleaning assembly 20 is mainly used as a structural member for performing cleaning work. The lifting mechanism 30 can drive the cleaning assembly 20 to rise.

[0043] Specifically, combined Figure 1-Figure 4 As shown, the cleaning assembly 20 is disposed below the machine body 10 , and the cleaning assembly 20 is a crawler-type cleaning component. The lifting mechanism 30 is disposed on the machine body 10 , and the lifting mechanism 30 is transmission-connected to the cleaning assembly 20 to selectively drive the cleaning assembly 20 to rise.

[0044] The cleaning assembly 20 uses a crawler-type cleaning element. Compared with a traditional roller brush that can only increase the number of bristles to increase the cleaning effect, the crawler-type cleaning element can achieve cleaning needs in different scenarios by changing the pressure of the brush head. For example, when cleaning a hard floor, the pressure of the brush head can be increased to increase the strength of the bristles, thereby cleaning the dirt faster and more thoroughly.

[0045] In addition, the cleaning component 20 is arranged below the body 10, so that the cleaning component 20 can directly contact the cleaning surface; the lifting mechanism 30 is arranged on the body 10, and the lifting mechanism 30 is transmission-connected with the cleaning component 20, so that the lifting mechanism 30 can drive the cleaning component 20 below the body 10 to selectively rise.

[0046] For example, when the crawler cleaning element is performing cleaning work (such as mopping or sweeping the floor), when it encounters special working environments such as carpets and obstacles, the lifting mechanism 30 can drive the cleaning component 20 to translate and rise as a whole to adapt to the current working environment (at this time the crawler cleaning element is not in contact with the cleaning surface); for another example, when the crawler cleaning element passes through a special working environment and encounters a conventional working environment such as a floor, the lifting mechanism 30 can drive the cleaning component 20 to translate and descend as a whole until the crawler cleaning element contacts the cleaning surface, thereby improving the adaptability of the cleaning device 100 in different working environments, and further improving the cleaning work efficiency of the cleaning device 100.

[0047] Therefore, by setting up the cleaning device 100, the cleaning component 20 can be selectively driven to move upward as a whole according to different working environments, so that the cleaning component 20 can adapt to the current working environment, thereby improving the cleaning work efficiency of the cleaning device 100.

[0048] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 2 , Figure 5-Figure 7 As shown, the cleaning assembly 20 includes a first base 21 and a track brush 22 . The first base 21 is disposed below the machine body 10 . The lifting mechanism 30 is transmission-connected to the first base 21 . The track brush 22 is disposed on the first base 21 .

[0049] Specifically, the track brush 22 is arranged below the first base 21, so that the track brush 22 can directly contact the surface to be cleaned, and the first base 21 can also form a certain protection and fixing effect on the track brush 22; and the lifting mechanism 30 is transmission-connected with the first base 21 below the body 10, so that the lifting mechanism 30 can indirectly achieve the effect of driving the track brush 22 to rise by driving the first base 21 to rise, thereby improving the design rationality and scientificity of the cleaning component 20.

[0050] Specifically, combined Figure 1-Figure 7 As shown, the lifting mechanism 30 is arranged in the machine body 10, the machine body 10 is provided with a through hole 11, and the first base 21 is provided with a connecting portion 211, and the connecting portion 211 is connected to the lifting mechanism 30 after passing through the through hole 11. Among them, since the lifting mechanism 30 and the first base 21 are respectively located at the upper and lower sides of the machine body 10, after the through hole 11 is provided in the machine body 10, it is convenient for the connecting portion 211 on the first base 21 to directly pass through the through hole 11 and be connected to the lifting mechanism 30 above. In this way, the transmission connection path between the lifting mechanism 30 and the first base 21 can be simplified and shortened, thereby improving the working efficiency of the lifting mechanism 30 driving the cleaning component 20 to rise.

[0051] Furthermore, combined with Figure 2-Figure 4 , Figure 6 As shown, the upper surface of the first base 21 is provided with an upper limit portion 212, and when the first base 21 rises to the upper limit position, the upper limit portion 212 is limitedly matched with the body 10. For example, when the lifting mechanism 30 drives the first base 21 to rise to the limit position, the upper surface of the upper limit portion 212 is limitedly matched with the lower surface of the body 10, so that the upward displacement of the cleaning component 20 can be limited, thereby avoiding the risk that the first base 21 will directly collide with the lower surface of the body 10 as the lifting mechanism 30 is driven, thereby improving the design rationality and safety of the cleaning component 20.

[0052] Specifically, combined Figure 1 and Figure 6 As shown, the upper limit portion 212 is constructed as a limiting ring arranged around the connecting portion 211, and the height of the limiting ring is less than the height of the connecting portion 211. The upper limit portion 212 surrounds the outer peripheral edge of the connecting portion 211. In the up-down direction, the height of the upper limit portion 212 is less than the height of the connecting portion 211, so that the upper limit portion 212 can form a limiting effect on the first base 21, and it can also ensure that the first base 21 has a certain rise margin, so that the cleaning component 20 can achieve a rising action within a certain range.

[0053] According to some optional embodiments of the present invention, combined with Figure 3 , Figure 4 and Figure 6As shown, the lifting mechanism 30 includes a driving member 31 and a transmission assembly 32. One end of the transmission assembly 32 is connected to the driving member 31, and the other end of the transmission assembly 32 is connected to the cleaning assembly 20. The driving member 31 selectively drives the cleaning assembly 20 to rise through the transmission assembly 32.

[0054] In detail, the two ends of the transmission assembly 32 are respectively connected to the driving member 31 and the cleaning assembly 20, and the driving member 31 can transmit the driving force to the cleaning assembly 20 through the transmission assembly 32, so as to achieve the effect of driving the cleaning assembly 20 to rise, thereby improving the scientificity and design rationality of the lifting mechanism 30. For example, the driving member 31 can be a motor, but is not limited thereto, so that the lifting effect of the cleaning assembly 20 can be achieved respectively by the forward and reverse rotation of the motor.

[0055] Specifically, combined Figure 3 , Figure 5 and Figure 6 As shown, the transmission assembly 32 includes a spool 321 and a pull wire 322, the spool 321 is connected to the driving member 31, one end of the pull wire 322 is connected to the spool 321, and the other end of the pull wire 322 is connected to the cleaning assembly 20. The spool 321 is synchronously connected to the driving member 31, and the two ends of the pull wire 322 are respectively connected to the spool 321 and the cleaning assembly 20, so that the spool 321 can be driven by the driving member 31 to rotate to wind the pull wire 322, thereby achieving the effect of shortening the height distance between the cleaning assembly 20 and the machine body 10, thereby achieving the lifting effect of the cleaning assembly 20.

[0056] Furthermore, combined with Figure 3 , Figure 5 and Figure 6 As shown, the transmission assembly 32 further includes a connecting member 323 , which is disposed in the machine body 10 and connected to the cleaning assembly 20 , and the other end of the pull wire 322 is connected to the connecting member 323 .

[0057] Among them, the connecting piece 323 in the body 10 is connected to the cleaning component 20, and the connecting piece 323 and the cleaning component 20 form a whole, and the other end of the pull wire 322 is connected to the connecting piece 323, so that the pull wire 322 can form an indirect connection relationship with the cleaning component 20, thereby achieving the effect of driving the cleaning component 20 to rise stably; and it can also avoid the need for the pull wire 322 to pass through or bypass the body 10 to connect to the cleaning component 20. This can reduce the layout route of the pull wire 322, thereby reducing the risk of wear and tear that the pull wire 322 may suffer, thereby improving the stability of the lifting mechanism 30 driving the cleaning component 20 to rise.

[0058] For example, if there is one connecting member 323, the connecting member 323 can be set close to the central axis of the body 10; if there are two connecting members 323, they can be set at intervals near the two ends of the body 10; of course, the position of the connecting member 323 can be adaptively adjusted according to the number, so that the connecting member 323 can smoothly drive the cleaning component 20 to move up and down.

[0059] Specifically, combined Figure 3-Figure 5 As shown, there are multiple connectors 323, which are arranged at intervals in the body 10, and the multiple connectors 323 are all connected to the cleaning component 20; there are multiple pull wires 322, one end of each of the multiple pull wires 322 is connected to the spool 321, and the other end of each of the multiple pull wires 322 is connected to the multiple connectors 323 one by one. Among them, the multiple connectors 323 arranged at intervals in the body 10 are all connected to the cleaning component 20, and the two ends of the multiple pull wires 322 are also correspondingly connected to the spool 321 and the multiple connectors 323, so that the force transmission path and force transmission size of the driving member 31 to the cleaning component 20 during the rising process can be increased, thereby improving the movement stability and responsiveness of the cleaning component 20 during the rising process.

[0060] Furthermore, combined with Figure 3-Figure 5 As shown, the cleaning assembly 20 is provided with a plurality of connecting parts 211, each connecting member 323 is connected to at least two connecting parts 211, and the other end of the pull wire 322 is connected to the center of the corresponding connecting part 211. Each connecting member 323 is connected to at least two connecting parts 211 on the cleaning assembly 20, so that the connection force transmission path between a single connecting member 323 and the cleaning assembly 20 can be increased, thereby improving the movement consistency and stability of the cleaning assembly 20 connected to the connecting member 323 driven by the pull wire 322 when ascending, and avoiding the problem of local collapse hysteresis (such as unevenness at both ends of the cleaning assembly 20) during the ascending process.

[0061] Specifically, combined Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the body 10 includes a bottom shell 12 and a second base 13, the cleaning component 20 is arranged below the bottom shell 12, the second base 13 is arranged above the bottom shell 12, the lifting mechanism 30 is arranged on the second base 13, and the cleaning component 20 has a connecting portion 211, which passes through the second base 13 and is connected to the connecting piece 323.

[0062] The second base 13 and the cleaning assembly 20 are respectively arranged above and below the bottom shell 12, and the lifting mechanism 30 is arranged on the second base 13, so that the lifting mechanism 30 can be further protected and fixed, and the lifting mechanism 30 can be easily disassembled and installed. The cleaning assembly 20 below the bottom shell 12 is connected to the connecting member 323 through its own connecting part 211 after passing through the second base 13, so that the cleaning assembly 20 and the lifting mechanism 30 can be smoothly connected, so that the lifting mechanism 30 can drive the cleaning assembly 20 to rise.

[0063] Furthermore, combined with Figure 6 As shown, a constraint portion 131 is provided on the second base 13, and a cable slot 1311 is formed on the constraint portion 131, and the pull wire 322 passes through the cable slot 1311. The constraint portion 131 is formed with a cable slot 1311 that constrains the moving path of the pull wire 322, and part of the pull wire 322 passes through the cable slot 1311 in the path connecting the spool 321 and the cleaning component 20, so that the moving path of the pull wire 322 can be limited, and the problem of the pull wire 322 shaking can be avoided, thereby ensuring the movement stability of the cleaning component 20 during the ascending process.

[0064] According to some optional embodiments of the present invention, combined with Figure 5 and Figure 6 As shown, the cleaning device 100 further includes an elastic return member 40 , which is disposed between the cleaning assembly 20 and the body 10 to provide an elastic force for the cleaning assembly 20 to descend.

[0065] Specifically, the elastic reset member 40 undergoes elastic deformation to generate an elastic force, and the elastic reset member 40 abuts against the cleaning component 20 body 10. When the cleaning component 20 needs to descend from the raised position, the lifting mechanism 30 stops working or reverses. In this way, under the combined action of the elastic reset force and the cleaning component 20's own gravity, the descending effect can be quickly completed until it contacts the cleaning surface. The cleaning component 20 continues to perform cleaning work (such as mopping, sweeping, etc.), and the elastic reset member 40 can also increase the friction between the crawler cleaning member and the cleaning surface, thereby improving the cleaning effect, thereby achieving the effect of the cleaning component 20 selectively performing an ascending or descending action.

[0066] Specifically, combined Figure 6 and Figure 7 As shown, the body 10 includes a bottom shell 12 and a second base 13, the cleaning component 20 is arranged below the bottom shell 12, the second base 13 is arranged above the bottom shell 12, the lifting mechanism 30 is arranged on the second base 13, and one end of the elastic reset member 40 abuts against the cleaning component 20 and the other end abuts against the bottom shell 12 or the second base 13.

[0067] For example, the bottom shell 12 is fixed relative to the body 10, the cleaning component 20 is movably arranged below the bottom shell 12, the second base 13 is fixed above the bottom shell 12, the lifting mechanism 30 is arranged on the second base 13, and the two ends of the elastic reset member 40 are respectively abutted between the cleaning component 20 and the bottom shell 12. In the process of the lifting mechanism 30 driving the cleaning component 20 to rise, the cleaning component 20 squeezes the elastic reset member 40, and the elastic reset member 40 forms an elastic reset force in the opposite direction. When the cleaning component 20 needs to descend, the elastic reset force is released. Under the action of the elastic reset force and its own gravity, the cleaning component 20 achieves a rapid descending effect until it contacts the cleaning surface. The cleaning component 20 continues to perform cleaning work (such as mopping, sweeping, etc.), and the elastic reset member 40 can also increase the friction between the crawler cleaning member and the cleaning surface, thereby improving the cleaning effect.

The cleaning assembly 20 is mainly used to perform cleaning work. The lifting mechanism 30 is mainly used to drive the cleaning assembly 20 to rise.

[0069] Specifically, the cleaning assembly 20 includes a first base 21 and a crawler brush 22, and the crawler brush 22 is arranged on the first base 21; the lifting mechanism 30 includes a driving member 31 and a transmission assembly 32, one end of the transmission assembly 32 is connected to the driving member 31, and the other end of the transmission assembly 32 is connected to the first base 21, and the driving member 31 selectively drives the first base 21 to rise through the transmission assembly 32.

[0070] In detail, combined Figure 1-Figure 3 As shown, the track brush 22 is connected to the first base 21, and the two ends of the transmission assembly 32 are respectively connected to the driving member 31 and the first base 21. When the track brush 22 is performing cleaning work (such as mopping or sweeping the floor), when it encounters special working environments such as carpets and obstacles, the lifting mechanism 30 can drive the cleaning assembly 20 to translate and rise as a whole to adapt to the current working environment, thereby improving the adaptability of the cleaning device 100 in different working environments, and then improving the cleaning work efficiency of the cleaning device 100.

[0071] Specifically, combined Figure 3 and Figure 6As shown, the transmission assembly 32 includes a spool 321 and a pull wire 322, the spool 321 is connected to the driving member 31, one end of the pull wire 322 is connected to the spool 321, and the other end of the pull wire 322 is connected to the cleaning assembly 20. The spool 321 is synchronously connected to the driving member 31, and the two ends of the pull wire 322 are respectively connected to the spool 321 and the cleaning assembly 20, so that the spool 321 can be driven by the driving member 31 to rotate to wind the pull wire 322, thereby achieving the effect of shortening the height distance between the cleaning assembly 20 and the machine body 10, thereby realizing the overall translation and ascending action of the cleaning assembly 20.

[0072] Furthermore, combined with Figure 3 , Figure 5 and Figure 6 As shown, the transmission assembly 32 also includes a connector 323, which is disposed in the machine body 10 and connected to the cleaning assembly 20, and the other end of the pull wire 322 is connected to the connector 323. The connector 323 in the machine body 10 is connected to the cleaning assembly 20, and the connector 323 and the cleaning assembly 20 form a whole, and the other end of the pull wire 322 is connected to the connector 323, so that the pull wire 322 can form an indirect connection relationship with the cleaning assembly 20, thereby achieving the effect of driving the cleaning assembly 20 to rise stably; and it can also avoid the need for the pull wire 322 to pass through or bypass the machine body 10 to connect to the cleaning assembly 20, so that the layout route of the pull wire 322 can be reduced, thereby reducing the risk of wear and tear of the pull wire 322, and thus improving the stability of the lifting mechanism 30 driving the cleaning assembly 20 to rise.
