[0057] like Figure 1 As shown, in the embodiment, a cleaning mechanism 1000 is provided, which can be applied to a surface cleaning device to provide a cleaning function for a surface to be cleaned. The surface cleaning device can be a sweeper, a mop or a desktop cleaning robot, and the surface to be cleaned can be the ground or a desktop.

[0058] like Figure 1 and Figure 2As shown, the cleaning mechanism 1000 is configured with a ground-proximal side 900, wherein the ground-proximal side 900 may refer to the side of the cleaning mechanism 1000 facing the surface to be cleaned. In addition, the cleaning mechanism 1000 also has a first direction X, a second direction Y, and a third direction Z that intersect each other. In an embodiment, the cleaning mechanism 1000 may include a base 100, a support assembly 200, a cleaning assembly 300, a crankshaft 400, and a drive assembly 500.

[0059] The support assembly 200 is movably mounted on a side of the base 100 close to the ground side 900. The cleaning assembly 300 is connected to a side of the support assembly 200 close to the ground side 900, and the cleaning assembly 300 can be used to provide a cleaning action.

[0060] like Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig. 9 As shown, the crankshaft 400 is rotatably connected to the base 100. In some embodiments, one end of the crankshaft 400 can be rotatably connected to the base 100 through a bearing 810, and the other end of the crankshaft 400 is also connected to a bearing 810, and the inner ring of the bearing 810 can be fixedly connected to the crankshaft 400. The bearing 810 is also sleeved with a bushing 820, and the bushing 820 can be fixedly connected to the outer ring of the bearing 810, and the bushing 820 is fixedly connected to the base 100. In this way, the crankshaft 400 can be rotatably connected to the base 100.

[0061] In the embodiment, the crankshaft 400 is disposed in the support assembly 200 , and the crankshaft 400 can rotate relative to the support assembly 200 . The axial direction of the crankshaft 400 can be parallel to the second direction Y. In addition, the crankshaft 400 is transmission-connected to the driving assembly 500 , and the driving assembly 500 can be installed in the base 100 .

[0062] During use, the driving assembly 500 can be used to drive the crankshaft 400 to rotate, so as to drive the cleaning assembly 300 to move along the first direction X through the bracket assembly 200 to achieve the cleaning function. At the same time, the cleaning assembly 300 can be driven by the bracket assembly 200 to move along the third direction Z to approach and move away from the surface to be cleaned. In this process, the cleaning assembly 300 can clean the dirt on the surface to be cleaned, for example, the dirt can be swept to the dirt collection port 2100 in the main body 2000 of the surface cleaning device, and the cleaning assembly 300 does not rotate during this process, thereby effectively reducing the probability of hair entangled in the cleaning assembly 300 and improving the cleaning effect.

[0063] like Figure 1 and Fig. 9As shown, when the cleaning mechanism 1000 is applied to a surface cleaning device, the electrical components in the cleaning mechanism 1000 can be electrically connected to a control module in a surface cleaning device host 2000, so that the control module can control the electrical components in the cleaning mechanism 1000 to operate.

[0064] like Figures 3 to 5 As shown, in some embodiments, the bracket assembly 200 may include a first bracket 210 and an adapter 220 .

[0065] The cleaning assembly 300 may be connected to a side of the first bracket 210 close to the ground side 900. In addition, the first bracket 210 is provided with an assembly cavity 211, and the assembly cavity 211 may have a certain extension length along the axial direction of the crankshaft 400. The adapter 220 may be disposed in the assembly cavity 211, and may be fixedly connected to the first bracket 210 by screw connection, bonding, or interference fit.

[0066] The adapter 220 may be provided with a waist-shaped hole 221, which may penetrate the adapter 220 along the axial direction of the crankshaft 400. In the embodiment, the crankshaft 400 may be roughly accommodated in the assembly cavity 211, and may pass through the waist-shaped hole 221 on the adapter 220. The crankshaft 400 is disposed in the first bracket 210, and the first bracket 210 may provide a protective function for the crankshaft 400, thereby reducing the possibility of hair contacting the crankshaft 400, thereby reducing the probability of the crankshaft 400 being entangled with hair, thereby reducing the problem of the crankshaft 400 being stuck.

[0067] In some embodiments, the length extension direction of the waist-shaped hole 221 may be parallel to the third direction Z. The size of the waist-shaped hole 221 in the first direction X may be equal to the diameter of the crankshaft 400 .

[0068] When the driving assembly 500 drives the crankshaft 400 to rotate, the crankshaft 400 can move in the waist-shaped hole 221 along the length extension direction of the waist-shaped hole 221. At the same time, the adapter 220 can be driven to move along the first direction X and the third direction Z, wherein the adapter 220 can transmit the action to the cleaning assembly 300 through the first bracket 210, so as to drive the cleaning assembly 300 to move along the first direction X and the third direction Z.

[0069] In some embodiments, the bracket assembly 200 may include two adapters 220 . The two adapters 220 may be disposed at two ends of the first bracket 210 along the axial direction of the crankshaft 400 , and the two adapters 220 are coaxially disposed.

[0070] In other embodiments, the support assembly 200 may also include one, three, or four adapters 220. When the support assembly 200 includes one adapter 220, the adapter 220 may be disposed at the center of the assembly cavity 211 in the axial direction of the crankshaft 400. When the support assembly 200 includes multiple adapters 220, the multiple adapters 220 may be symmetrically or evenly distributed in the assembly cavity 211, and the crankshaft 400 may be sequentially inserted into the waist-shaped holes 221 in the multiple adapters 220, which may also improve the stability of the crankshaft 400 during rotation.

[0071] In addition, the adapter 220 can be made of silicone, which has elasticity and high wear resistance and corrosion resistance. During the rotation of the crankshaft 400, the adapter 220 can absorb the vibration of the crankshaft 400 accordingly to reduce the transmission of the vibration of the crankshaft 400, achieve a shock absorption effect, and also achieve a noise reduction effect.

[0072] In other embodiments, the adapter 220 may also be made of flexible materials such as rubber.

[0073] like Figures 2 to 4 As shown, in some embodiments, the cleaning mechanism 1000 further includes a rotating member 610, which is rotatably connected to a side of the base 100 close to the ground side 900. The rotation axis of the rotating member 610 may be parallel to the axis of the crankshaft 400, that is, parallel to the second direction Y.

[0074] The side of the first bracket 210 away from the near-ground side 900 can be fixedly connected with a connecting rod 620 by means of integral molding, screw connection or bonding. The end of the connecting rod 620 away from the first bracket 210 can be inserted into the rotating member 610 and can be telescopically slid relative to the rotating member 610. The direction in which the connecting rod 620 telescopically slides relative to the rotating member 610 can be parallel to the height direction of the cleaning mechanism. When the driving assembly 500 drives the crankshaft 400 to rotate and drives the first bracket 210 to move along the third direction Z through the adapter 220, the connecting rod 620 can telescopically move relative to the rotating member 610.

[0075] In other embodiments, one end of the connecting rod 620 away from the first bracket 210 can be slidably inserted into the base 100, and a through hole through which the active connecting rod 620 passes can be opened in the base 100. The diameter of the through hole can be larger than the outer diameter of the connecting rod 620, thereby allowing the connecting rod 620 to swing in the through hole.

[0076] like Figure 7 and Figure 8As shown, in other embodiments, the bracket assembly 200 may include a second bracket 230. The second bracket 230 may include an integrated bracket body 231 and a connecting arm 232. The cleaning assembly 300 may be connected to a side of the bracket body 231 close to the near-ground side 900. The connecting arm 232 is protrudingly disposed on a side of the bracket body 231 away from the cleaning assembly 300. The waist-shaped hole 221 may be provided on the connecting arm 232 and may penetrate the connecting arm 232 along the axial direction of the crankshaft 400. In an embodiment, the crankshaft 400 may be inserted into the waist-shaped hole 221 on the connecting arm 232 to transmit power to the second bracket 230. The connecting rod 620 may be fixedly connected to an end of the connecting arm 232 away from the bracket body 231.

[0077] like Figures 2 to 4 As shown, in some embodiments, the cleaning mechanism 1000 further includes an elastic member 630, which can be sleeved around the connecting rod 620. One end of the elastic member 630 can abut against the side of the rotating member 610 facing the first bracket 210, and the other end of the elastic member 630 can abut against the side of the first bracket 210 facing the connecting rod 620. When the cleaning component 300 is close to the surface to be cleaned, the elastic member 630 can be in a compressed state, so that the cleaning component 300 can apply a certain pressure to the surface to be cleaned to improve the cleaning effect.

[0078] Of course, in other embodiments, when the cleaning assembly 300 is located close to the surface to be cleaned, the elastic member 630 may be in a naturally extended state.

[0079] In some embodiments, the elastic member 630 can be a spring.

[0080] In other embodiments, the elastic member 630 may also be a spring sheet or a flexible column.

[0081] like Figure 1 , Fig. 9 and Fig.11 As shown, during the process of the driving assembly 500 driving the crankshaft 400 to rotate, when the bracket assembly 200 drives the cleaning assembly 300 from the end close to the sewage collecting port 2100 to gradually move away from the sewage collecting port 2100, the crankshaft 400 can gradually move from the end of the waist-shaped hole 221 close to the near-ground side 900 to the end away from the near-ground side 900, and the bracket assembly 200 can gradually squeeze the elastic member 630 and make the elastic member 630 store corresponding elastic potential energy. The cleaning assembly 300 can also be separated from the surface to be cleaned to avoid carrying dirt from the sewage collecting port 2100 to the far end.

[0082] like Figure 1 , Fig.10 and Fig.11As shown, when the bracket assembly 200 drives the cleaning assembly 300 from the end away from the sewage collecting port 2100 to gradually approach the sewage collecting port 2100, the crankshaft 400 can move from the end of the waist-shaped hole 221 away from the ground side 900 to the end close to the ground side 900, and the elastic member 630 can act on the bracket assembly 200 and make the bracket assembly 200 drive the cleaning assembly 300 to move along the third direction Z towards the surface to be cleaned, so that the cleaning assembly 300 is pressed against the surface to be cleaned to clean the dirt on the surface to be cleaned toward the sewage collecting port 2100, so that the dirt enters the sewage collecting box of the main unit 2000 through the sewage collecting port 2100 to realize the cleaning function.

[0083] During this process, the cleaning component 300 moves in parallel to the third direction Z and in parallel to the first direction X simultaneously without any rotation, thereby effectively avoiding the problem of the cleaning component 300 being entangled with hair.

[0084] In other embodiments, the support assembly 200 and the cleaning assembly 300 may also move from an end away from the surface to be cleaned to a direction close to the surface to be cleaned under the action of gravity or under the driving action of the driving assembly 500. Accordingly, the cleaning mechanism 1000 may not need to be provided with the elastic member 630.

[0085] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the crankshaft 400 is also connected to a roller 710, and the roller 710 can be rotatably mounted on the crankshaft 400, and the rotation axis of the roller 710 can be parallel to the axial direction of the crankshaft 400. The roller 710 can be mounted on a section of the crankshaft 400 located in the assembly cavity 211. In the embodiment, the roller 710 can be rotatably connected to the crankshaft 400 through a rotating shaft 720. Specifically, two opposite bearing blocks 410 can be protrudingly provided on the peripheral side of the crankshaft 400, and the two bearing blocks 410 can be arranged relatively spaced along the axial direction of the crankshaft 400. The two ends of the rotating shaft 720 are fixedly connected to the two bearing blocks 410 one by one, and the roller 710 is rotatably sleeved on the rotating shaft 720. In some embodiments, a bearing 810 can also be arranged between the roller 710 and the rotating shaft 720.

[0086] In some other embodiments, two ends of the rotating shaft 720 are rotatably connected to the two bearing blocks 410 through bearings 810 in a one-to-one correspondence, and the roller 710 can be fixedly sleeved on the rotating shaft 720 .

[0087] When the driving assembly 500 drives the crankshaft 400 to rotate, the roller 710 can roll with the inner wall of the assembly cavity 211. Thus, the stability of the crankshaft 400 during movement can be further improved, the vibration of the crankshaft 400 and the bracket assembly 200 can be reduced, and the effects of shock absorption and noise reduction can be achieved.

[0088] In some embodiments, the roller 710 may be a flexible roller made of silica gel, which may have a certain buffering effect and further achieve the effect of shock reduction and noise reduction. At the same time, the roller 710 may have the characteristics of wear resistance and corrosion resistance.

[0089] In other embodiments, the roller 710 may also be made of flexible materials such as rubber.

[0090] In the embodiment, one, two, three, five or other rollers 710 may be installed on the crankshaft 400 as required, and no specific limitation is made herein.

[0091] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the driving assembly 500 may include a driving member 510, a gear box 520 and a transmission gear 530. The driving member 510 may be a motor. The driving member 510 and the gear box 520 may be fixedly installed in the base 100. The output shaft of the driving member 510 may be connected to a gear in the gear box 520. Another gear in the gear box 520 may be meshed with the transmission gear 530. The transmission gear 530 may be fixedly installed at one end of the crankshaft 400.

[0092] When the driving member 510 drives the gear box 520 to operate, the crankshaft 400 can be driven to rotate through the transmission gear 530 .

[0093] like Figure 3 and Fig. 9 As shown, the cleaning assembly 300 may include a scraper bar 310 and a brush bar 320. Both the brush bar 320 and the scraper bar 310 may be fixedly connected to the side of the first bracket 210 away from the connecting rod 620 by injection molding, clamping or gluing. The brush bar 320 may be located on one side of the scraper bar 310, and the brush bar 320 may be spaced apart from the scraper bar 310. When the driving assembly 500 drives the cleaning assembly 300 to move along the first direction X through the bracket assembly 200, the brush bar 320 may sweep the dirt on the surface to be cleaned toward the dirt collection port 2100, and the scraper bar 310 may scrape the fine dirt on the surface to be cleaned toward the dirt collection port 2100, so as to improve the cleaning effect.

[0094] In other embodiments, the cleaning component 300 may also include structures such as a cleaning brush.

[0095] The embodiment also provides a surface cleaning device, which may include a main unit and a cleaning mechanism 1000 provided in the embodiment. The cleaning mechanism 1000 may be installed on the main unit 2000 and may be located on one side of the dirt collection port 2100 .
