The appearances of the phrase that in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely examples from a whole class of comparable embodiments which are claimed as falling within the scope of the present application.

[0058] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the overall structure of the cleaning device in some embodiments of the present application, Figure 2 is Figure 1 a sectional view of the cleaning device in the embodiments. The present application provides a cleaning device, which comprises a body 60 and a cleaning mechanism 10.

[0059] The cleaning mechanism 10 is connected to the body 60, and the cleaning mechanism 10 comprises a cleaning body 11, a bracket 12, a pollution collection assembly 13 and a pollution suction pipe 14, wherein the bracket 12 is wrapped outside part of the cleaning body 11, and the cleaning body 11 can move relative to the body 60 with the bracket 12; the two ends of the pollution suction pipe 14 are respectively in sealing connection with the bracket 12 and the pollution collection assembly 13, and the pollution collection assembly 13 is used for collecting the sewage on the cleaning body 11.

[0060] With the above scheme, when the cleaning device performs the cleaning task, the cleaning body 11 and the bracket 12 can move synchronously relative to the body 60, the bracket 12 can always wrap the dirty part of the cleaning body 11 inside, and since the two ends of the suction pipe 14 are respectively sealedly connected with the bracket 12 and the dirt collecting assembly 13, the suction pipe 14 also moves synchronously with the bracket 12. The sewage or garbage on the cleaning body 11 can be collected in the dirt collecting assembly 13 through the suction pipe 14, compared with an open water tank, it can effectively avoid the sewage or garbage falling on the ground when the cleaning device accelerates, decelerates or vibrates. It should be noted that the suction pipe 14 should be made of a material that is easy to deform, such as rubber, flexible plastic or the like, so as to ensure that the suction pipe 14 maintains sealed connection with the bracket 12 and the dirt collecting assembly during movement with the bracket 12.

[0061] In some embodiments, the dirt collecting assembly 13 includes a sewage box 131, the sewage box 131 is fixed relative to the body 60, and the sewage box 131 is sealedly connected with the suction pipe 14. The body 60 includes a shell 61, the sewage box 131 is fixedly connected with the shell 61, and the sewage box 131 is a hollow closed structure.

[0062] Optionally, the sewage box 131 is located below the cleaning body 11, and the end of the suction pipe 14 connected with the sewage box 131 is lower than the end of the suction pipe 14 connected with the bracket 12, so that the sewage or garbage on the cleaning body 11 can be collected into the sewage box 131 under the action of gravity.

[0063] Please refer to Figure 2 and Figure 3 , Figure 3 is Figure 1Figure 6 is a schematic view of a partial structure of the cleaning device in an embodiment. Optionally, the dirt collecting assembly 13 further comprises a negative pressure component 132 connected with the dirt box 131, which can generate a negative pressure in the dirt box 131 to collect the dirt and water on the cleaning body 11 into the dirt box 131. The relative position between the dirt box 131 and the cleaning body 11 is not specifically limited in the embodiment. The negative pressure component 132 comprises a fan 1322 which is in communication with the dirt box 131 through an air duct 1321. The specific structure of the fan 1322 is familiar to those skilled in the art, and will not be described here. The blades of the fan 1322 can generate a large air flow in the process of rotation, which can suck the gas inside the dirt box 131 away, resulting in a negative pressure area in the dirt box 131 relative to the outside, and thus the dirt and water on the cleaning body 11 can be sucked into the dirt box 131 through the dirt suction pipe 14 for storage. In particular, the air outlet of the fan 1322 can be horizontally arranged on the shell 61. When the cleaning device is close to the wall for cleaning, the air outlet of the fan 1322 can face the wall to blow the dust on the wall to the ground, and then the ground can be cleaned by the cleaning body 11. The negative pressure component 132 can also be a suction pump or other negative pressure generator familiar to those skilled in the art.

[0064] Referring to Figure 4 , Figure 4 Figure 7 is a schematic view of a partial explosion of the cleaning device in another embodiment. In some embodiments, the body 60 is provided with a first driving mechanism 20 connected with the support 12, which can drive the support 12 and the cleaning body 11 to move in a first direction, so that the cleaning body 11 has a first position and a second position. The length of the cleaning body 11 extending out of the body 60 when the cleaning body 11 is in the first position is greater than the length of the cleaning body 11 extending out of the body 60 when the cleaning body 11 is in the second position. It can be understood that when the cleaning body 11 is in the first position, the cleaning body 11 at least partially extends out of the peripheral edge of the body 60; when the cleaning body 11 is in the second position, the cleaning body 11 can be completely retracted into the body 60, or partially retracted into the body 60 relative to the first position. When the cleaning device is cleaning along the wall, the cleaning body 11 of the cleaning device will be driven by the first driving mechanism 20 to expand outwards to the first position with the support 12 and adhere to the wall for cleaning, ensuring that the wall area is cleaned in place.

[0065] Referring to Figure 5 , Figure 5 is Figure 4Schematic diagram of the structure of the second drive mechanism in an embodiment. Exemplarily, the first drive mechanism 20 includes a first drive member 21 and a first transmission assembly 22, wherein the first drive member 21 is fixed relative to the body 60 in a first direction. The first transmission assembly 22 is disposed between the first drive member 21 and the bracket 12. Driven by the first drive member 21, the first transmission assembly 22 drives the bracket 12 and the cleaning body 11 to move.

[0066] Optionally, the first driving member 21 is directly fixedly installed inside the shell 61, and a receiving groove 63 can be set through the bottom of the shell 61 along the moving direction of the cleaning body 11 to install and accommodate the cleaning body 11 and the bracket 12, so that the first driving mechanism 20 can drive the bracket 12 to drive the cleaning body 11 to move back and forth between the first position and the second position.

[0067] The first transmission assembly 22 includes, but is not limited to, an air cylinder, an oil cylinder, a crank-connecting rod mechanism, etc. Optionally, the first transmission assembly 22 includes a gear and a rack that mesh with each other. The gear is key-connected to the first driving member 21 and rotates under the drive of the first driving member 21. The rack is fixedly connected to the bracket 12. As the gear rotates, the rack drives the bracket 12 and the cleaning body 11 to move in the first direction.

[0068] Optionally, the first transmission assembly 22 includes a screw rod 221 and a moving member 222. The screw rod 221 extends in a first direction and is connected to the first driving member 21. The screw rod 221 can rotate about its own axis under the drive of the first driving member 21. The moving member 222 is threadedly connected to the screw rod 221, and the moving member 222 is connected to the bracket 12. The first driving member 21 may include a motor that directly drives the screw rod 221 to rotate. The first driving member 21 may also include a reduction gearbox, and the motor drives the screw rod 221 to rotate through the reduction gearbox, so that the moving member 222 drives the bracket 12 and the cleaning body 11 to move.

[0069] Further, the moving piece 222 is detachably connected with the bracket 12. The moving piece 222 comprises a threaded part 2221 and an insertion block 2222, the threaded part 2221 is threadedly connected with the screw rod 221, the insertion block 2222 is fixedly connected with the threaded part 2221, and the insertion block 2222 protrudes from the threaded part 2221. The bracket 12 is provided with a limiting groove 127, the insertion block 2222 is inserted into the limiting groove 127, and the insertion block 2222 is in abutment with the groove walls of the limiting groove 127 on opposite sides in the first direction, so as to limit the relative movement of the bracket 12 and the moving piece 222 in the first direction. It can be understood that the positions of the insertion block 2222 and the limiting groove 127 can be interchanged, for example, the insertion block 2222 is arranged on the bracket 12, and the limiting groove 127 is arranged on the moving piece 222, as long as the bracket 12 and the moving piece 222 can not move relative to each other in the first direction. By arranging the insertion block 2222 and the limiting groove 127, the relative movement of the bracket 12 and the moving piece 222 can be limited, and the bracket 12 and the first driving mechanism 20 can be conveniently disassembled and assembled.

[0070] Please refer to Figure 6 and Figure 7 , Figure 6 is Figure 1 Another partial structure schematic diagram of the cleaning equipment in the embodiment, Figure 7 is Figure 6 A partial explosion schematic diagram of the cleaning equipment in the embodiment. In some embodiments, the cleaning main body 11 of the cleaning equipment can not only move relative to the body 60 in the first direction, but also move relative to the body 60 in a second direction. The body 60 is provided with a support frame 40, the support frame 40 is fixed relative to the body 60 in the first direction, and the first driving mechanism 20 is installed on the support frame 40. In this embodiment, the first driving mechanism 20 also adopts the first driving piece 21 and the first transmission assembly 22, and the first transmission assembly 22 comprises the screw rod 221 and the moving piece 222. The difference between this embodiment and the above-mentioned embodiments is that the first driving piece 21 is fixed on the support frame 40, and the first driving piece 21 is arranged on the side of the support frame 40 away from the cleaning main body 11 and the bracket 12, the support frame 40 is provided with a avoiding hole 43, the bracket 12 passes through the avoiding hole 43 and is connected with the moving piece 222 of the first driving mechanism 20. Optionally, a first guide assembly 50 is arranged between the support frame 40 and the bracket 12, the first guide assembly 50 comprises a first guide rail 51 and a first sliding block 52, the first guide rail 51 is fixedly arranged on one of the support frame 40 and the bracket 12, the first guide rail 51 extends in the first direction, and the first sliding block 52 is fixedly arranged on the other one of the support frame 40 and the bracket 12, and the first sliding block 52 is slidingly connected with the first guide rail 51 in the first direction. In this embodiment, the first guide rail 51 is fixedly arranged on the support frame 40, the first sliding block 52 is fixedly arranged on the bracket 12, and the first guide rail 51 is provided with four first guide rails to ensure the smoothness of the bracket 12 when moving relative to the support frame 40 in the first direction.

[0071] Please refer to Figure 8 and Figure 9 , Figure 8 is Figure 1 the explosion schematic diagram of the cleaning device in the embodiment, Figure 9 is Figure 8 the structural schematic diagram of the second driving mechanism in the embodiment. The second driving mechanism 30 is arranged on the body 60, and the second driving mechanism 30 can drive the support frame 40 and the cleaning main body 11 to move relative to the body 60 along the second direction, so that the cleaning main body 11 has a third position in contact with the surface to be cleaned and a fourth position spaced from the surface to be cleaned, and the cleaning main body 11 and the support frame 12 are fixed relative to the support frame 40 in the second direction. When the cleaning device needs to clean the ground, the second driving mechanism 30 drives the support frame 40 to move along the second direction, and the support frame 40 drives the support frame 12 and the cleaning main body 11 to move to the third position to contact the ground. When the cleaning device encounters an obstacle, the second driving mechanism 30 drives the second support frame 40 to move along the second direction, and the support frame 40 drives the support frame 12 and the cleaning main body 11 to move to the fourth position to avoid the obstacle.

[0072] Please refer to Figure 6 and Figure 9 For example, the second driving mechanism 30 includes a winding assembly 33 and a pulling rope 31. One end of the pulling rope 31 is connected with the support frame 40, and the other end of the pulling rope 31 is wound on the winding assembly 33 and drives the support frame 12 and the cleaning main body 11 to move along the second direction under the driving of the winding assembly 33. The winding assembly 33 includes a second driving piece 331 and a winding wheel 332. The pulling rope 31 is wound on the winding wheel 332, and the second driving piece 331 is fixedly installed inside the shell 61. The second driving piece 331 is used to drive the winding wheel 332 to rotate, so that the pulling rope 31 drives the support frame 40 to move along the second direction, and the support frame 40 drives the support frame 12 and the cleaning main body 11 to move along the second direction, so that the cleaning main body 11 moves away from the surface to be cleaned or approaches the surface to be cleaned. In order to improve the convenience of connecting the pulling rope 31 and the support frame 40, the pulling rope 31 in the embodiment is provided with an abutting portion 311, the support frame 40 is provided with an abutting hole 44, one side of the abutting hole 44 is provided with a gap, and the size of the abutting hole 44 and the gap is greater than the size of the pulling rope 31 and less than the size of the abutting portion 311. After the pulling rope 31 is moved into the abutting hole 44 along the gap, the abutting portion 311 is abutted to one side of the support frame 40 facing the support frame 12 by the winding assembly 33 to tighten the pulling rope 31, so that the pulling rope 31 and the support frame 40 are locked and connected without using a locking piece, which is convenient to operate and reliable in connection.

[0073] Further, the at least part of the pulling rope 31 is externally sleeved with a sleeve 32, and the pulling rope 31 is slidable relative to the sleeve 32. The pulling rope 31 is made of steel wire, which has a large tensile strength and can bear a large pulling force. The sleeve 32 is made of rubber material, which has the properties of wear resistance and corrosion resistance and can effectively prevent the pulling rope 31 from being worn and broken. It can be understood that the sleeve 32 is not wound on the winding wheel 332, and the length of the sleeve 32 is fixed. When the pulling rope 31 is reeled in or unreeled under the driving of the winding assembly 33, the pulling rope 31 slides in the sleeve 32.

[0074] In some embodiments, the second direction is a vertical direction, and a second guide assembly (not shown in the figure) is arranged between the support frame 40 and the shell 61. The second guide assembly includes a second guide rail and a second sliding block. The second guide rail is fixedly arranged on one of the support frame 40 and the shell 61, and extends along the second direction. The second sliding block is fixedly arranged on the other one of the support frame 40 and the shell 61, and is slidingly connected to the second guide rail along the second direction.

[0075] The second driving mechanism 30 can also have other structures, such as an electric push rod, a pneumatic cylinder, an oil cylinder, and other linear driving mechanisms familiar to those skilled in the art.

[0076] Please refer to Figure 10 , Figure 10 is Figure 1The cleaning device in the embodiment is shown in a sectional view of another cross section. In some embodiments, the second direction is perpendicular to the horizontal direction and the trajectory of the second direction is in an arc shape. Exemplarily, the support frame 40 is rotationally connected to the housing 61 through a first rotation shaft 62, and the axial direction of the first rotation shaft 62 is parallel to the first direction. Specifically, the support frame 40 includes a first connection position 41 that is relatively fixed and a second connection position 42, the support frame 40 is rotationally connected to the housing 61 at the first connection position 41, and the support frame 40 is connected to the second driving mechanism 30 at the second connection position 42. The projection of the first connection position 41 and the second connection position 42 on the first plane does not coincide, and the first plane is a reference plane perpendicular to the first direction. Among them, the distance from the first connection position 41 to the surface to be cleaned can be less than the distance from the second connection position 42 to the surface to be cleaned, and the first connection position 41 is located obliquely below the second connection position 42. In combination with the implementation mode of the winding assembly 33 and the pull rope 31 of the second driving mechanism 30, the second connection position 42 is connected to the pull rope 31, and the pull rope 31 drives the second connection position 42 of the support frame 40 to rotate around the first connection position 41 under the drive of the winding assembly 33, so as to drive the cleaning main body 11 to ascend and descend. Since the projection of the first connection position 41 and the second connection position 42 on the first plane does not coincide, and the first connection position 41 and the second connection position 42 are relatively fixed, that is, a force arm is formed between the first connection position 41 and the second connection position 42 of the support frame 40, and an external force is applied to the second connection position 42 through the pull rope 31, it is not necessary to lift the support frame 40, the support frame 12 and the cleaning main body 11 as a whole, and only a small force is needed to realize the ascending and descending of the cleaning main body 11.
