The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] like Figure 1 and Figure 2 As shown, a cleaning device 100 of an embodiment of the present invention is used to clean an object to be cleaned. The structure of the cleaning device 100 of the present application is described below by taking the cylindrical floor brush 200 of a vacuum cleaner as an example. This embodiment is only used as an example and does not limit the technical scope of the present application. It is understood that in other embodiments, the cleaning device 100 can also be used to clean other structures, which is not limited here.

[0036] Please continue reading Figure 1 The cleaning device 100 includes a cleaning container 20, a limiting structure 40 and a cleaning structure. The cleaning container 20 is used to contain cleaning liquid such as water, the limiting structure 40 is used to limit the floor brush 200 in the cleaning container 20, and the cleaning structure is used to drive the floor brush 200 to rotate in the cleaning liquid, thereby cleaning the floor brush 200.

[0037] The cleaning container 20 includes a water tank 21 and a support seat 23 installed in the water tank 21 . The water tank 21 is used to contain cleaning liquid. The limiting structure 40 and the cleaning structure are detachably installed in the water tank 21 through the support seat 23 .

[0038] like Figure 3 , Figure 4 and Figure 5As shown, the water tank 21 includes a water tank body 212 and a piston assembly 214 detachably connected to the water tank body 212. The water tank body 212 is generally a cubic shell structure. In this application, the length direction of the water tank body 212 is defined as the first direction, the width direction of the water tank body 212 is defined as the second direction, and the height direction of the water tank body 212 is defined as the third direction. The water tank body 212 includes a water tank bottom wall 211 and a water tank side wall 213 formed by extending the edge of the water tank bottom wall 211 in the same direction. The water tank side wall 213 surrounds the outer periphery of the water tank bottom wall 211 to form a cleaning chamber with one end open together with the water tank bottom wall 211.

[0039] The water tank bottom wall 211 is provided with a water outlet 2112 connecting the cleaning chamber with the external environment, and the piston assembly 214 is detachably mounted on the water outlet 2112 to open or close the water outlet 2112. In this way, when the piston assembly 214 closes the water outlet 2112, water can be stored in the water tank body 212 to clean the floor brush 200. When cleaning is completed, the user can manipulate the piston assembly 214 to open the water outlet 2112, and the sewage in the water tank body 212 can be discharged through the water outlet 2112.

[0040] Furthermore, in some embodiments, the water tank bottom wall 211 is inclined relative to the horizontal plane, and the water tank bottom wall 211 extends obliquely from the water tank side wall 213 toward the water outlet hole 2112, and the distance between the water tank side wall 213 and the opening end of the cleaning chamber decreases monotonically. In this way, the water outlet hole 2112 is opened at the lowest point of the water tank bottom wall 211 in the vertical direction, and the water in the water tank body 212 can flow out quickly through the water outlet hole 2112 under the action of gravity, thereby avoiding water residue in the water tank body 212.

[0041] One end of the piston assembly 214 is detachably inserted into the water outlet 2112 along the third direction to open or close the water outlet 2112, and the other end of the piston assembly 214 extends out of the cleaning cavity to be held by the user.

[0042] Specifically, the piston assembly 214 includes a piston rod 2141, a seal 2143 and a stopper 2145. The piston rod 2141 is a columnar structure extending in a straight line, and the seal 2143 is sleeved on one end of the piston rod 2141. The outer diameter of the seal 2143 matches the inner diameter of the water outlet 2112, and the seal 2143 can produce a recoverable elastic deformation under the action of an external force. In this way, the seal 2143 can be detachably inserted into the water outlet 2112 along the third direction, thereby effectively closing the water outlet 2112 to prevent water leakage in the water tank body 212. One end of the piston rod 2141 away from the seal 2143 extends out of the cleaning cavity along the third direction for the user to hold. A limit piece 2145 is provided at one end of the piston rod 2141 extending out of the cleaning chamber. The limit piece 2145 includes a limit piece body and a positioning column. The limit piece body is pressed against the end surface of the side wall 213 of the water tank away from the bottom wall 211 of the water tank. Two positioning columns are protruded from the limit piece body and pressed against the side surface of the side wall 213 of the water tank and are arranged at intervals in the circumferential direction. Two positioning holes are provided at one end of the side wall 213 of the water tank away from the bottom wall 211 of the water tank. The two positioning columns can be respectively inserted into the two positioning holes, so that the limit piece 2145 is limited to the opening end of the cleaning chamber.

[0043] In this way, the seal 2143 is embedded in the water outlet 2112 to block the water outlet 2112, and the piston rod 2141 is vertically limited to the cleaning container 20 by the limiter 2145. When the sewage needs to be discharged, the user can hold the limiter 2145 and apply a pulling force to separate the seal 2143 from the water outlet 2112 without touching the sewage with his hands.

[0044] like Figure 2 and Figure 5 As shown, the upper edge of the support seat 23 is supported on the end surface of the side wall 213 of the water tank away from the bottom wall 211 of the water tank, and the main body of the support seat 23 is located in the cleaning chamber to install the limiting structure 40 and the cleaning structure. The limiting structure 40 and the cleaning structure are respectively located on both sides of the water tank body 212 in the first direction.

[0045] See also Figure 2 , Figure 5 and Figure 6 The limiting structure 40 is detachably mounted on the water tank body 212, and the limiting structure 40 is used to form a limiting space to accommodate the floor brush 200. In this way, the user can remove the limiting structure 40 from the water tank body 212, and then limit the floor brush 200 in the limiting space, and finally install the limiting structure 40 on the water tank body 212 so that the limiting space is located in the cleaning cavity, so that the floor brush 200 is limited in the cleaning cavity.

[0046] Specifically, the limiting structure 40 includes a first limiting clip 41 and a second limiting clip 43. The first limiting clip 41 includes a first connection portion 412 and a first limiting portion 414 and a first operating portion 416 connected at both ends of the first connection portion 412, and the second limiting clip 43 includes a second connection portion 432 and a second limiting portion 434 and a second operating portion 436 connected at both ends of the second connection portion 432.

[0047] The first connection part 412 is rotatably connected to the second connection part 432, and the rotation axis of the first connection part 412 and the second connection part extends along the first direction. The cross-sections of the first limiting part 414 and the second limiting part 434 perpendicular to the first direction are both arc-shaped, and the first limiting part 414 and the second limiting part 434 jointly form a limiting space with a cross-section that is roughly circular and matches the shape of the floor brush 200, and the central axis of the floor brush 200 limited in the limiting space extends along the first direction. The first control part 416 and the second control part 436 are spaced from each other in the second direction and are connected to each other through the limiting clip connector 45, and the end of the first control part 416 away from the second control part 436 can be detachably supported on the water tank side wall 213 in the third direction, and the end of the second control part 436 away from the first control part 416 can be detachably supported on the water tank side wall 213 in the third direction. In some embodiments, the limiting clip connector 45 is a spring.

[0048] In this way, when the user applies a force to the first control part 416 and the second control part 436 to make the two move closer to each other in the second direction, the first connection part 412 and the second connection part 432 rotate, driving the first limiting part 414 and the second limiting part 434 to separate from each other, and the radial size of the limiting space increases to facilitate the installation or removal of the floor brush 200. After the user limits the floor brush 200 between the first limiting part 414 and the second limiting part 434 or removes the floor brush 200, the first control part 416 and the second control part 436 can be loosened, and the first control part 416 and the second control part 436 are separated from each other under the action of the limiting clamp connector, so that the first limiting part 414 and the second limiting part 434 move closer to each other again to limit the floor brush 200.

[0049] like Figure 5 As shown, the cleaning structure includes a first clamping member 61, a second clamping member 63, a clamping mechanism 65 and a rotating mechanism 67. The first clamping member 61 and the second clamping member 63 are respectively located on both sides of the limiting space in the first direction, the clamping mechanism 65 drives the first clamping member 61 and the second clamping member 63 to adjust the distance in the first direction under the action of an external force to clamp the floor brush 200, and the rotating mechanism 67 drives the first clamping member 61 and the second clamping member 63 to rotate synchronously around the first direction under the action of an external force or automatically to drive the floor brush 200 to rotate.

[0050] Specifically, Figure 5 , Figure 7and Fig. 9 As shown, the first clamping member 61 includes a first clamping member body 612, a first clamping cushion 614 and a first bearing 616. The first clamping cushion 614 is fixed to one end of the first clamping member body 612 to contact the end surface of the floor brush 200, and two first bearings 616 are sleeved on the other end of the first clamping member body 612 and are interference fit with the first clamping member 61.

[0051] like Figure 5 , Figure 8 and Fig. 9 As shown, the second clamping member 63 includes a second clamping member body 632, a second clamping cushion 634, a second bearing 636 and a clamping member transmission wheel 638. The second clamping member body 632 is fixedly connected to one end of the second clamping member body 632 to contact the end surface of the floor brush 200, two second bearings 636 are sleeved in the middle of the second clamping member body 632 and are interference fit with the second clamping member body 632, and the clamping member transmission wheel 638 is connected to one end of the second clamping member body 632 away from the second clamping cushion 634.

[0052] Please continue reading Figure 5 and Fig. 9 The clamping mechanism 65 includes a clamping transmission member 652 , a separation assembly 654 and a clamping member 656 . The separation assembly 654 and the clamping member 656 drive the first clamping member 61 to move in the first direction through the clamping transmission member 652 .

[0053] Specifically, the clamping transmission member 652 includes a clamping transmission member body 6521, one end of which is provided with a first connection hole, and one end of the first clamping member 61 provided with a first bearing 616 extends into the first connection hole, and the outer ring of the first bearing 616 is interference-fitted with the first connection hole. A second connection hole is provided at the other end of the clamping transmission member body 6521, and a connection column that cooperates with the clamping member 656 is protruded outwardly from the bottom wall of the second connection hole. In this way, the first clamping member 61 can rotate relative to the clamping transmission member 652 around the first direction through the first bearing 616 while following the clamping transmission member 652 to move linearly along the first direction.

[0054] Furthermore, the clamping transmission member 652 further includes a limiting rib 6523 protruding from the side wall of the clamping transmission member body 6521, and the support seat 23 is provided with a limiting groove extending along the first direction, and the limiting rib 6523 can be limited in the limiting groove and move along the first direction. In this way, the clamping transmission member 652 can only move linearly in the first direction under the limiting action of the limiting rib 6523.

[0055] One end of the clamping member 656 is sleeved on the connecting column of the clamping transmission member 652, and the other end of the clamping member 656 is fixed to the support seat 23. The clamping member 656 has a recoverable elastic deformation to apply a thrust to the clamping transmission member 652 toward the second clamping member 63. In one embodiment, the clamping member 656 is a spring.

[0056] Please continue reading Figure 5 and Fig. 9 The separation component 654 includes a pulley assembly 653 and a knob assembly 655 that are matched with each other. The user can rotate the knob assembly 655 to manually drive the pulley assembly 653 to operate. The pulley assembly 653 converts the rotation of the knob assembly 655 into a linear motion of the clamping transmission member 652 along the first direction away from the second clamping member 63.

[0057] Specifically, the knob assembly 655 includes a knob 6552 and a knob rod 6554. The knob rod 6554 extends in the second direction, one end of the knob rod 6554 is limited to the water tank side wall 213 on one side in the second direction, the other end of the knob rod 6554 extends out of the water tank side wall 213 on the other side in the second direction, and the knob 6552 is connected to the end of the knob rod 6554 extending out of the water tank side wall 213 and abuts against the outer surface of the water tank side wall 213. The knob 6552 is provided with a plurality of first limiting teeth arranged in the circumferential direction, and the outer surface of the water tank side wall 213 is provided with a plurality of second limiting teeth 2132 which are interference-fitted with the first limiting teeth. In this way, when the user turns the knob 6552, the first limiting tooth on the knob 6552 overcomes the resistance of the second limiting tooth 2132 to drive the knob rod 6554 to rotate. When the user stops turning the knob 6552, the blocking effect of the second limiting tooth 2132 can prevent the knob 6552 from automatically reversing.

[0058] The pulley block 653 includes a driving wheel 6532, a driven wheel 6534 and a flexible member 6536. The driving wheel 6532 is sleeved on the knob rod 6554 to rotate with the knob rod 6554. The driven wheel 6534 is located on a side of the clamping transmission member 652 away from the second clamping member 63 in the first direction, and is used to change the direction of the force. The flexible member 6536 is a long strip-shaped flexible structure such as a soft rope or a soft cord. One end of the flexible member 6536 is fixedly connected to the driving wheel 6532, and the other end of the flexible member 6536 passes around the driven wheel 6534 to connect the clamping transmission member 652.

[0059] In this way, the driving wheel 6532 can rotate along with the knob rod 6554 to recycle or release the flexible member 6536. When the driving wheel 6532 recycles the flexible member 6536 so that one end of the flexible member 6536 gradually wraps around the driving wheel 6532, the end of the flexible member 6536 connected to the clamping transmission member 652 applies a pulling force in the first direction to the clamping transmission member 652, so that the first clamping member 61 moves away from the second clamping member 63 in the first direction. At this time, the user can install the limiting structure 40 on the water tank body 212, with the floor brush 200 located between the first clamping member 61 and the second clamping member 63, or remove the limiting structure 40 from the water tank body 212. When the driving wheel 6532 rotates in the opposite direction to release the flexible member 6536, the force of the flexible member 6536 on the clamping transmission member 652 disappears, and the clamping member 656 pushes the clamping transmission member 652 to move toward the second clamping member 63, so that the first clamping member 61 and the second clamping member 63 move closer to each other to clamp the floor brush 200.

[0060] Please continue reading Figure 5 and Fig. 9 The rotating mechanism 67 includes a power supply, a driving member and a transmission assembly. The power supply supplies power to the driving member, and the driving member is connected to the second clamping member 63 through the transmission assembly. The driving member drives the second clamping member 63 to rotate around the first direction through the transmission assembly 674.

[0061] Specifically in one embodiment, the driving member is a motor 672, and the transmission assembly is a bevel gear transmission assembly 674, which includes a driving bevel gear 6741, a first bevel gear 6742 and a second bevel gear 6743. Among them, the central axis of the driving shaft of the motor 672 extends along the first direction, and the driving bevel gear 6741 is sleeved on the driving shaft of the motor 672. The central axis of the first bevel gear 6742 extends along the third direction to mesh with the driving bevel gear 6741. The first bevel gear 6742 and the second bevel gear 6743 are connected by a transmission rod 6744, and the transmission rod 6744 is rotatably mounted on the support seat 23 around the third direction through a bearing, and the central axis of the first bevel gear 6742 coincides with the central axis of the second bevel gear 6743. The clamping member transmission wheel 638 of the second clamping member 63 is a bevel gear and meshes with the second bevel gear 6743, and the central axis of the clamping member transmission wheel 638 extends along the first direction.

[0062] Thus, the motor 672 sequentially drives the first bevel gear 6742 and the second bevel gear 6743 to drive the second clamping member 63 to rotate around the first direction. It can be understood that the specific structure of the transmission assembly is not limited, and transmission assemblies of different structures can be provided as needed.

[0063] like Fig.10 and Fig.11As shown, in other embodiments, the driving member is a rocker 676, and the transmission assembly is a transmission gear set 678. One end of the rocker 676 is connected to the transmission gear set 678, and the other end extends out of the water tank body 212. The transmission gear set 678 includes a first transmission wheel 6781 and a second transmission wheel 6783. The first transmission wheel 6781, the second transmission wheel 6783 and the clamping member transmission wheel 638 on the second clamping member 63 are spur gears. The number of teeth of the first transmission wheel 6781, the second transmission wheel 6783 and the clamping member transmission wheel 638 decreases in sequence. The center position of the first transmission wheel 6781 is fixedly connected to the rocker 676, and the second transmission wheel 6783 is meshed with the first transmission wheel 6781 and the clamping member transmission wheel 638 at the same time. The central axes of the first transmission wheel 6781, the second transmission wheel 6783 and the clamping member transmission wheel 638 all extend along the first direction.

[0064] In this way, the user can hold the rocker 676 and apply torque to the rocker 676 to rotate the rocker 676, thereby driving the second clamping member 63 to rotate through the transmission assembly 674, and finally driving the floor brush 200 to rotate. Since the number of teeth of the first transmission wheel 6781, the second transmission wheel 6783 and the clamping member transmission wheel 638 decreases successively, when the rocker rotates one circle, the second clamping member 63 can drive the floor brush 200 to rotate for several circles, thereby saving the user's effort while realizing manual control. Since the rotation of the floor brush 200 is driven by the user turning the rocker 676, different speeds and times can be manually selected as needed. Moreover, the entire cleaning device 100 can clean the floor brush 200 without connecting to a power source, thereby increasing the application scope of the cleaning device 100, expanding the use scenarios of the cleaning device 100, and saving energy and being green and environmentally friendly.

[0065] The steps of cleaning the floor brush 200 by the cleaning device 100 are as follows:

[0066] First, the user manually removes the limiting structure 40 from the water tank body 212, and presses the first operating part 416 of the first limiting clip 41 and the second operating part 436 of the second limiting clip 43 to open the limiting space. After placing the floor brush 200 into the limiting space, the first limiting clip 41 and the second limiting clip 43 are released, and the floor brush 200 can rotate around its own central axis to be limited in the limiting space.

[0067] Then, the user places the limiting structure 40 on the water tank body 212, and turns the knob 6552 to drive the first clamping member 61 to move toward the second clamping member 63 to clamp the floor brush 200 in the limiting space.

[0068] Afterwards, water or other cleaning liquid is injected into the water tank body 212. When the water in the water tank body 212 reaches a preset water level, the user starts the motor 672, and the second clamping member 63 and the first clamping member 61 jointly drive the floor brush 200 to rotate around the first direction, thereby achieving cleaning of the floor brush 200. In some embodiments, the user can manually rock the lever 676 to achieve the rotation of the floor brush 200.

[0069] Finally, after the floor brush 200 is cleaned, the user turns off the motor 672 and rotates the knob 6552 in the opposite direction to move the first clamping member 61 away from the second clamping member 63. The user can remove the limiting structure 40 and remove the floor brush 200 from the limiting structure 40, and remove the piston assembly 214 to open the water outlet 2112, and the sewage in the water tank body 212 is discharged to the external environment.

[0070] The cleaning device 100 can conveniently clamp and clean the floor brush 200 of the vacuum cleaner, and the sewage after cleaning can be conveniently discharged from the water tank 21, thereby bringing convenience to people's lives and improving the cleaning efficiency of the vacuum cleaner equipped with the floor brush 200.

[0071] The technical features of the above-described embodiments may be arbitrarily combined.
