[0034] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a separate or alternative embodiment in isolation from other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with each other.
[0035] The embodiments of the present application provide a cleaning device, please refer to Figures 1 to 3 , such as but not limited to a robot vacuum cleaner, a robot sweeper and mop, a robot sweeper and washer, etc. The cleaning device includes a cleaning module 10 and a device body 20. The cleaning module 10 is mounted on the device body 20; the cleaning module 10 includes a driving motor 110, a first rotating member 120, and a cleaning member 130, the driving motor 110 is used to drive the first rotating member 120 to rotate in a first direction D1 or a second direction D2 opposite to the first direction D1, the cleaning member 130 is used to clean a to-be-cleaned area, the cleaning member 130 is configured to be lifted relative to the first rotating member 120 when the first rotating member 120 rotates, the cleaning module 10 further includes an elastic member 140, the elastic member 140 is used to hinder the rotation of the cleaning member 130 relative to the device body 20 in the second direction D2, so that the cleaning member 130 rotates relative to the first rotating member 120 in the first direction D1 and rises, the elastic member 140 is configured such that the resistance to the rotation of the cleaning member 130 in the second direction D2 is greater than the resistance to the rotation of the cleaning member 130 in the first direction D1.
[0036] Further, the number of cleaning pieces 130 can be one or more, and the cleaning pieces 130 can be a mop or a brush.
[0037] Optionally, the first direction D1 can be a clockwise direction in a top-down view of the cleaning device, and the second direction D2 can be an anticlockwise direction opposite to the first direction D1. In some other embodiments, the first direction D1 can also be an anticlockwise direction, and the second direction D2 can also be a clockwise direction. When the driving motor 110 drives the first rotating piece 120 to rotate in the first direction D1, the first rotating piece 120 can drive the cleaning piece 130 to descend away from the device main body 20, and at this time, the cleaning piece 130 is less resistant to rotation in the first direction D1, so the first rotating piece 120 can drive the cleaning piece 130 to rotate in the first direction D1 to clean the area to be cleaned. When the driving motor 110 drives the first rotating piece 120 to rotate in the second direction D2, the cleaning piece 130 is more resistant to rotation in the second direction D2 due to the blocking effect of the elastic piece 140, so the first rotating piece 120 can rotate in the second direction D2 relative to the cleaning piece 130, thereby driving the cleaning piece 130 to ascend to be close to the device main body 20.
[0038] In some embodiments, the elastic piece 140 can form a clamping joint with the cleaning piece 130, so that the cleaning piece 130 cannot rotate in the second direction D2 relative to the device main body 20. In some other embodiments, the cleaning piece 130 can rotate in the second direction D2 relative to the device main body 20 under the driving of the driving motor 110 against the damping effect of the elastic piece 140, and the cleaning piece 130 can slow down to a stop under the damping effect of the elastic piece 140 to avoid damage to the motor of the driving motor 110 due to motor stall.
[0039] Optionally, as shown in Figures 4 to 6 the cleaning module 10 includes a housing 150 fixed relative to the device main body 20, the cleaning piece 130 is connected to a second rotating piece 160 at an end facing the driving motor 110, the second rotating piece 160 is arranged in the housing 150, the second rotating piece 160 and the cleaning piece 130 cannot rotate relative to each other, and the elastic piece 140 is located between the second rotating piece 160 and the housing 150. The elastic piece 140 is configured such that the second rotating piece 160 is more resistant to rotation in the second direction D2 relative to the housing 150 than to rotation in the first direction D1 relative to the housing 150.
[0040] Optionally, as shown in Figure 7 and Figure 8As shown, the elastic member 140 includes a fixed portion 141 and a movable portion 142, the fixed portion 141 is fixedly connected with the shell 150, one end of the movable portion 142 is connected with the fixed portion 141, and the other end is provided with an abutting end 143. The second rotating member 160 is provided with a clamping groove 1601, and the clamping groove 1601 is provided with an abutting surface 161. The abutting end 143 is pressed on the second rotating member 160 under the action of the elastic force. When the second rotating member 160 rotates in the first direction D1, the second rotating member 160 slides relative to the abutting end 143, and the second rotating member 160 is subjected to smaller pressure in the circumferential direction by the abutting end 143. When the second rotating member 160 rotates in the second direction D2, the abutting end 143 abuts against the abutting surface 161, and the second rotating member 160 is subjected to larger pressure in the circumferential direction by the abutting end 143, thereby generating larger resistance to hinder rotation.
[0041] Further, as shown in Figure 3 、 Figure 10 and Figure 11 , the shell 150 includes a first shell 151 and a second shell 152, and an inner cavity 1501 is formed between the first shell 151 and the second shell 152. The driving motor 110 is arranged on the side of the first shell 151 away from the second shell 152. The second shell 152 is provided with a mounting groove 1502 in communication with the inner cavity 1501, and the second rotating member 160 is at least partially arranged in the mounting groove 1502. The side wall of the mounting groove 1502 is provided with a first connecting groove 1503, the shape of the first connecting groove 1503 matches the shape of the fixed portion 141, and the fixed portion 141 is embedded in the first connecting groove 1503. The movable portion 142 can at least partially extend into the mounting groove 1502, and the abutting end 143 can extend into the mounting groove 1502 under the action of the elastic force and press against the second rotating member 160.
[0042] Specifically, the elastic member 140 can be a one-piece spring, the fixed portion 141 is embedded in the shell 150, and the movable portion 142 is bent and connected to the fixed portion 141. In some embodiments, the spring is fixed by means of an internal sleeve of a mold, the elastic member 140 can be fixed in the second shell 152 by insert injection molding, the material of the elastic member 140 can be a metal material with elasticity, and the material of the second shell 152 can be hard plastic. The present application adjusts the resistance of the cleaning member 130 in different rotating directions by using the spring structure, realizes the lifting of the cleaning member 130, and has the advantages of small volume, low cost and simple installation.
[0043] In some other embodiments, the elastic member 140 can also be a spring structure, one end of the spring is fixed on the shell 150, the abutting end 143 is located at the end of the spring away from the shell 150, the abutting end 143 has a tendency to extend into the mounting groove 1502 away from the shell 150 under the elastic action, so as to extend into the clamping groove 1601 and abut against the abutting surface 161 when the second rotating member 160 rotates towards the second direction D2.
[0044] Further, as shown in Figure 7 , the fixed part 141 can include a first section 1411, a second section 1412 and a third section 1413, the second section 1412 can be connected to one end of the first section 1411 in the counterclockwise direction, the third section 1413 can be connected to one end of the second section 1412 away from the first section 1411 in the counterclockwise direction, the movable part 142 can be connected to one end of the third section 1413 away from the second section 1412 in the counterclockwise direction, and the elastic member 140 can be folded to form a rectangular structure, so that the fixed part 141 can be better fixedly connected with the shell 150 and is not easy to be separated from the shell 150. In some other embodiments, the shape of the elastic member 140 can also be triangular, circular or other shapes.
[0045] Optionally, as shown in Figure 6 and Figure 8 , the clamping groove 1601 is provided with a sliding surface 162 connected with the abutting surface 161, the sliding surface 162 is inclinedly arranged, and the sliding surface 162 is connected between the abutting surface 161 and the side surface of the second rotating member 160. The sliding surface 162 gradually approaches the rotation axis L of the second rotating member 160 in the first direction D1; the sliding surface 162 is used to guide the abutting end 143 to slide away from the clamping groove 1601 when the second rotating member 160 rotates towards the first direction D1, and the sliding surface 162 is also used to guide the abutting end 143 to slide to the abutting position with the abutting surface 161 when the second rotating member 160 rotates towards the second direction D2.
[0046] Optionally, the elastic member 140 is a one-piece spring sheet, the fixed part 141 is embedded in the shell 150, and the movable part 142 extends from one end of the fixed part 141, and the extension direction of the movable part 142 is in the same direction as the first direction D1, so that the movable part 142 can be elastically deformed to increase and leave the clamping groove 1601 under the pressure action of the second rotating member 160 when the second rotating member 160 rotates towards the first direction D1.
[0047] Further, the number of the elastic members 140 can be one or more, and the number of the clamping grooves 1601 can be one or more. Specifically, the number of the clamping grooves 1601 can be four and uniformly distributed around the second rotating member 160, and the number of the elastic members 140 can be two and distributed on both sides of the second rotating member 160.
[0048] Optionally, the abutting surface 161 is configured to form an angle with the active portion 142, which is less than or equal to 90 degrees, when the abutting end 143 abuts against the abutting surface 161 on the side of the active portion 142 away from the second rotating member 160. Specifically, the extending direction of the active portion 142 can be parallel to the sliding surface 162 when the abutting surface 161 abuts against the abutting end 143, and the angle between the abutting surface 161 and the sliding surface 162 is less than or equal to 90 degrees.
[0049] Optionally, the abutting surface 161 can pass through the rotation axis L of the second rotating member 160 and be perpendicular to the sliding surface 162. The second rotating member 160 can have a substantially circular profile, and the abutting surface 161 can be perpendicular to the side surface of the second rotating member 160. When the abutting surface 161 abuts against the abutting end 143, the active portion 142 can be perpendicular to the abutting surface 161.
[0050] In some other embodiments, the abutting surface 161 is configured to form an angle with the active portion 142, which is greater than 90 degrees, when the abutting end 143 abuts against the abutting surface 161 on the side of the active portion 142 away from the second rotating member 160. Specifically, the extending direction of the active portion 142 can be parallel to the sliding surface 162 when the abutting surface 161 abuts against the abutting end 143, and the angle between the abutting surface 161 and the sliding surface 162 is greater than 90 degrees.
[0051] Specifically, when the second rotating member 160 rotates in the second direction D2 and the abutting end 143 abuts against the abutting surface 161, the abutting surface 161 forms an abutting angle A with the active portion 142 on the side of the active portion 142 away from the second rotating member 160. When the abutting angle A is equal to 90 degrees, the pressure of the abutting surface 161 on the active portion 142 is directed along the length direction of the active portion 142, so that the abutting end 143 cannot slide on the abutting surface 161 to achieve the locking of the second rotating member 160. When the abutting angle A is less than 90 degrees, the abutting end 143 can slide in the direction close to the rotation axis L under the pressure of the abutting surface 161, and be clamped at the intersection of the abutting surface 161 and the sliding surface 162, so that the second rotating member 160 stops rotating. When the abutting angle A is greater than 90 degrees, the abutting end 143 can slide in the direction away from the rotation axis L under the pressure of the abutting surface 161, so that the abutting end 143 slides out of the clamping groove 1601, and the elastic member 140 provides damping effect without locking the second rotating member 160, so that the second rotating member 160 can continue to rotate in the second direction D2, and the driving motor 110 can slow down to a stop under the damping effect of the elastic member 140 to avoid the damage caused by the motor stall.
[0052] Optionally, as shown in FIG. 6, the abutting surface 161 can be a flat surface, and the abutting end 143 can be a flat end. Figure 12 and Figure 13As shown, the first rotating member 120 is provided with a limiting hole 1201, the cleaning member 130 comprises a transmission part 131 and a cleaning part 132 connected with each other, the transmission part 131 is inserted into the limiting hole 1201, the limiting hole 1201 is provided with a first end 1202 and a second end 1203, in the direction of the rotation axis of the first rotating member 120, the distance from the first end 1202 to the driving motor 110 is greater than the distance from the second end 1203 to the driving motor 110, that is, the distance from the first end 1202 to the device main body 20 is greater than the distance from the second end 1203 to the device main body 20. The transmission part 131 is configured to move to the first end 1202 when the first rotating member 120 rotates relative to the cleaning member 130 in the first direction D1, so as to drive the cleaning part 132 to descend relative to the device main body 20; the transmission part 131 is also configured to move to the second end 1203 when the first rotating member 120 rotates relative to the cleaning member 130 in the second direction D2, so as to drive the cleaning part 132 to ascend relative to the device main body 20.
[0053] Optionally, the material of the transmission part 131 is an elastic material, and the transmission part 131 is further configured to bend towards the driving motor 110 when the first rotating member 120 rotates in the second direction D2, so as to drive the cleaning part 132 to ascend relative to the device main body 20.
[0054] Further, the first rotating member 120 comprises a first rotating shell 121 and a second rotating shell 122, a mounting cavity 1204 is formed between the first rotating shell 121 and the second rotating shell 122, a first through hole 1205 is formed on the first rotating shell 121, and the second rotating shell 122 is provided with a second connecting pipe 123 on the side facing the first rotating shell 121, and the second connecting pipe 123 is inserted into the first through hole 1205. The limiting hole 1201 can be formed by combining a gap on the first rotating shell 121 and a gap on the second rotating shell 122, and an inclined guide rail can be formed between the first end 1202 and the second end 1203 of the limiting hole 1201 to guide the movement of the transmission part 131 between the first end 1202 and the second end 1203.
[0055] Optionally, as Figure 4 , Figure 14 and Figure 15As shown, the first rotating member 120 is provided with a mounting cavity 1204, and the cleaning member 130 is at least partially arranged in the mounting cavity 1204.

The first connecting pipe 1331 is connected with the second rotating member 160. When the first rotating member 120 rotates in the second direction D2 under the driving of the driving motor 110, the second rotating member 160 is resisted by the elastic member 140, so that the cleaning member 130 connected with the second rotating member 160 relatively rotates with the first rotating member 120. The transmission portion 131 moves to the second end 1203 and abuts against the inner wall of the limiting hole 1201 at the second end 1203. At this time, if the first rotating member 120 continues to rotate in the second direction D2, the main body 133 and the transmission portion 131 are subjected to different forces, and the transmission portion 131 is twisted and deformed to lift the cleaning portion 132. In some other embodiments, the transmission portion 131 can be partially pulled into the mounting cavity 1204 to further lift the cleaning portion 132. Specifically, the main body 133 can be made of hard plastic or metal material.
[0056] Further, the number of the cleaning portions 132 can be one or more. Specifically, the number of the cleaning portions 132 can be three and evenly distributed around the main body 133. The number of the transmission portions 131 corresponds to the number of the cleaning portions 132. The number of the limiting holes 1201 also corresponds to the number of the cleaning portions 132.

[0058] Further, as shown in Figure 9 , Figure 14 and Figure 16 , the first rotating member 120 is provided with a second connecting pipe 123, the second connecting pipe 123 is inserted into the first connecting pipe 1331, the driving motor 110 is connected with a rotating shaft 114, the second rotating member 160 is provided with a second through hole 1602, the rotating shaft 114 passes through the second through hole 1602 and is inserted into the second connecting pipe 123, and the second connecting pipe 123 is fixedly connected with the rotating shaft 114.
[0059] Specifically, the rotating shaft 114 can be fixedly connected with the second connecting pipe 123 by a screw, the cross-sectional shape of the rotating shaft 114 can match the inner profile of the second connecting pipe 123, and the cross-sectional shape of the rotating shaft 114 is non-circular, for example, the cross-sectional shape of the rotating shaft 114 can be a regular hexagon, so that the rotating shaft 114 and the second connecting pipe 123 cannot rotate relative to each other. The second rotating member 160 is provided with a second connecting groove 1603 on the side facing the cleaning member 130, the cross-sectional shape of the second connecting groove 1603 matches the outer profile of the first connecting pipe 1331, and the cross-sectional shape of the second connecting groove 1603 is non-circular, for example, the cross-sectional shape of the second connecting groove 1603 can be a regular hexagon, so that the first connecting pipe 1331 and the second rotating member 160 cannot rotate relative to each other. The inner profile of the first connecting pipe 1331 can be circular, and the outer profile of the second connecting pipe 123 can be circular, so that when the second connecting pipe 123 is inserted into the first connecting pipe 1331, the first connecting pipe 1331 and the second connecting pipe 123 can rotate relative to each other to realize the relative rotation of the cleaning member 130 and the first rotating member 120.
[0060] Further, the rotating shaft 114 and the second connecting pipe 123 are detachably connected, and the second rotating member 160 and the first connecting pipe 1331 can also be detachably connected.
[0061] Optionally, as shown in Figure 3 The driving motor 110 is connected with the first gear 111, the second gear 112 and the third gear 113 between the first rotating member 120, the rotating shaft of the driving motor 110, the first gear 111, the second gear 112, the third gear 113 are sequentially driven, and the rotating shaft 114 is fixedly connected to the third gear 113 and fixedly connected with the second connecting pipe 123 through the second shell 152.
[0062] When the cleaning device descends the cleaning member 130 to clean, the driving motor 110 drives the first rotating member 120 to rotate in the first direction D1 through the first gear 111, the second gear 112 and the third gear 113, and the cleaning member 130 moves relative to the first rotating member 120 under the action of frictional resistance and gravity, and the transmission part 131 moves from the second end 1203 to the first end 1202 along the limiting hole 1201 and abuts against the inner wall of the first end 1202. At this time, the elastic member 140 and the second rotating member 160 rotate in the same direction, the resistance is small, and the cleaning member 130 rotates synchronously with the first rotating member 120 under the pressure of the inner wall of the first end 1202, so as to clean the area to be cleaned.
[0063] When the cleaning device lifts the cleaning component 130, the drive motor 110 drives the first rotating component 120 to rotate in the second direction D2 via the first gear 111, the second gear 112, and the third gear 113. At this time, the elastic component 140 and the second rotating component 160 are in opposite directions, resulting in high resistance and making it difficult or impossible for the cleaning component 130 to rotate. Meanwhile, the first rotating component 120 will rotate relative to the cleaning component 130. The transmission part 131 moves from the first end 1202 to the second end 1203 relative to the first rotating component 120, abutting against the inner wall of the second end 1203, thus achieving the lifting action of the cleaning component 130. When the first rotating component 120 continues to rotate in the second direction D2, the transmission part 131 will obstruct the rotation of the first rotating component 120, thereby stopping the drive motor 110.
[0064] The cleaning device provided in this application, by setting the elastic element 140, allows the cleaning element 130 to rotate and perform cleaning work with less resistance in the first direction D1, and the cleaning element 130 to be lifted with greater resistance in the second direction D2. The structure is simple, which helps to reduce costs and size. At the same time, it can avoid the drive motor 110 from stalling, which has a protective effect on the drive motor 110 and can improve the reliability of the cleaning device.

Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
