[0046] The present application provides a kind of cleaning equipment and its cleaning device 100.The specific performance form of cleaning equipment is not limited, for example, it can be hand-held cleaning equipment, it can also be self-propelled cleaning equipment etc..Cleaning equipment includes machine body, cleaning device 100 is suitable for being installed on the machine body of cleaning equipment, preferably installed on the lower side of machine body, to realize the cleaning of the surface to be cleaned with machine body movement, wherein cleaning equipment can be sweeper, mop, sweeping and mopping integrated machine, scrubber, etc., the surface to be cleaned can include but not limited to ground, wall surface, table surface, window surface, furniture surface etc..

[0047] It can be understood that when the cleaning device is a self-propelled cleaning device, it can also include a walking driving mechanism for driving the body to automatically walk along the surface to be cleaned, and auxiliary walking components such as rollers can also be installed on the body. The cleaning device 100 specifically includes a cleaning piece 46, which refers to a component that directly contacts the surface to be cleaned to achieve friction cleaning of the surface to be cleaned. The specific type thereof depends on the specific type of the cleaning device, and the cleaning piece selectively contacts or moves away from the cleaning surface according to the specific working scene of the cleaning device 100. For the convenience of description, in this embodiment, the cleaning piece 46 can be a side brush, which is used to contact the cleaning surface for cleaning when the cleaning device performs sweeping work, and is lifted away from the cleaning surface to avoid secondary pollution of the cleaning surface and protect the side brush itself from being collided when the cleaning surface performs mopping work or only walks and overcomes obstacles.

[0048] Please refer to Figures 1 to 12 The utility model provides a kind of cleaning device, and cleaning device specifically includes shell, drive assembly, actuating piece and cleaning assembly, wherein drive assembly is installed in shell, preferably installed in the interior of shell. As shown in Figure 4 , drive assembly specifically should include motor, speed reducer and drive shaft, and motor is drivingly connected with drive shaft by speed reducer to drive its rotation, and the specific structure of speed reducer is not limited, and the speed reducer includes multi-stage speed reducer in this embodiment. It needs to be explained that in this embodiment, forward rotation can be one of clockwise or counterclockwise rotation of drive shaft, and reverse rotation refers to the rotation of drive shaft in the direction opposite to forward rotation.

[0049] Please refer to Figure 4 And Figures 6 to 12 Actuating piece is rotatably arranged relative to shell, and drive assembly is drivingly connected with actuating piece to drive actuating piece to rotate. Cleaning assembly is also rotatably arranged relative to shell, and includes the cleaning piece in the above. Specifically, cleaning assembly has first end relatively close to actuating piece, and second end relatively away from actuating piece, and preferably, the end of cleaning piece can constitute second end. When cleaning assembly rotates, second end rotates around the outer periphery of first end, and cleaning assembly has lifting state that second end is relatively close to first end in up-down direction, and lowering state that second end is relatively away from first end in up-down direction.

[0050] In the active stroke of the driving assembly driving the actuating member to rotate, the actuating member acts on the first end to switch the cleaning assembly between the lifting state and the lowering state. Specifically, when the cleaning assembly needs to be cleaned by the cleaning member, for example, in the sweeping mode of the cleaning device, the actuating member can act on the first end in its rotating stroke to make the second end lower to contact the cleaning surface, and the cleaning assembly rotates normally for cleaning. When the cleaning assembly does not need to be cleaned by the cleaning member, for example, in the walking mode or the mopping mode, the actuating member can act on the first end again to make the second end lift away from the cleaning surface, and the cleaning assembly also does not rotate for cleaning. In the utility model, the cleaning device uses the actuating member arranged in rotation to actuate the cleaning assembly. Compared with the actuating member arranged in up-down movement, the actuating member needs smaller occupied space and does not need a complex transmission mechanism to connect the motor, which can effectively compress the size of the cleaning device in the up-down direction, has simple structure and is easy to maintain, is not prone to failure, and reduces the maintenance cost of the cleaning device.

[0051] Further, please refer to Figure 6 and Figure 10 The cleaning assembly comprises a mounting part and a cleaning member. In this example, the cleaning member can be a brush bundle comprising a plurality of bristles, or other material structures having a sweeping effect, such as a rubber strip. The mounting part is used to fix the brush bundle, which can be resin, rubber, silicone or the like, and the cleaning member is preferably injection molded into the mounting part. In this way, the overall structure of the cleaning assembly can be a replaceable consumable part. The mounting part at least partially constitutes the first end, the cleaning member is fixed to the mounting part, and the end of the cleaning member away from the mounting part constitutes the second end. During the action of the actuating member on the first end, the mounting part at least partially displaces and / or elastically deforms to relatively approach or move away from the first end in the up-down direction. Specifically, the mounting part can be a rigid material, at this time the displacement of the mounting part makes the second end move up and down, or the mounting part can comprise an elastic material, at this time the elastic deformation of the mounting part makes the second end move up and down. In the preferred embodiment, part of the structure of the mounting part has displacement and elastic deformation under the action of the actuating member, and then drives the cleaning member to act, so that the second end of the cleaning member rises away from the cleaning surface. In this way, on the one hand, the cleaning member has sufficient lifting away from the cleaning surface, and on the other hand, the elastic deformation of the actuating member itself drives the cleaning member to lift, which needs small space, and the cleaning member does not need to be installed in a rotating manner, which is convenient for assembly and replacement, and the elastic actuating member can also more firmly keep the cleaning assembly in the lifting state.

[0052] Preferably, please continue to refer to Figure 6 and Figure 10, the mounting portion comprises a mounting ring and a leg extending outward from the mounting ring, and preferably the mounting ring is integrally arranged on the leg. The leg comprises a first segment and a second segment which are sequentially connected and arranged at an angle away from the mounting ring, the first segment constitutes the first end, and the second segment is bent downward relative to the first segment, and the cleaning member is fixed on the second segment. During the switching of the cleaning assembly from the lowered state to the lifted state, the actuating member acts on the first segment to press the first segment downward, and at the same time, the second segment is raised upward to drive the second end to rotate upward. In the embodiment, the downward bending structure of the leg itself is used to make the first segment press downward under the action of the actuating member, and the second segment is raised like a lever. In this way, the cleaning assembly has a very simple and easy-to-replace structure, and the second end has a larger displacement in the up-down direction in a smaller space, and the lifting effect of the cleaning member is good.

[0053] Preferably, a plurality of legs are arranged, and the plurality of legs are distributed along the circumference of the mounting ring.

[0054] Specifically, please refer to Figures 6 to 9 In the first embodiment provided by the utility model, the actuating member has a downwardly arranged guide slope, and it can be understood that when a plurality of legs are arranged, a plurality of guide slopes should also be arranged along the circumference. The guide slope extends downwardly and upwardly in the circumferential direction, and is correspondingly arranged above the first segment. In the embodiment, during the switching of the cleaning assembly from the lowered state to the lifted state, the actuating member rotates, and at the same time, the guide slope is correspondingly abutted on the upper side of the first segment to gradually press the first segment downward, so that the second segment is raised upward to drive the second end on the cleaning member to rotate upward and away from the cleaning surface. In this way, the actuating member has a simple and reliable structure, and in the limited space size in the up-down direction, the cleaning member has sufficient lifting effect.

[0055] And in the second embodiment provided by the utility model, please refer to Figures 10 to 12 The actuating member comprises an outwardly protruding guide key, and it can be understood that when a plurality of legs are arranged, a plurality of guide keys should also be arranged along the circumference. The protruding height of the guide key gradually changes along the circumference, and the lower side of the first segment is correspondingly provided with an acting key. During the rotation stroke of the actuating member, the guide key pushes the acting key outward to make the first segment deform and be pressed downward. In the embodiment, during the switching of the cleaning assembly from the lowered state to the lifted state, the actuating member rotates, and at the same time, the guide slope is correspondingly abutted on the upper side of the first segment to gradually press the first segment downward, so that the second segment is raised upward to drive the second end on the cleaning member to rotate upward and away from the cleaning surface. In this way, the actuating member has a simple and reliable structure, and in the limited space size in the up-down direction, the cleaning member has sufficient lifting effect.

[0056] On the basis of the above embodiments, please continue to refer to Figure 6 And Figure 10, the second section is deflected relative to the first section around the first direction, so that the cleaning member also generates a torsional action of rotating around the first direction during the switching of the cleaning assembly from the lowered state to the lifted state. In this way, when the cleaning member is in the lowered state, the second end thereof is in linear contact with the cleaning surface, the contact area is large, and the cleaning effect is good. When the cleaning member is switched to the lifted state, the second end is not only rotated upward relative to the first end, but also is twisted to a certain extent, so that the cleaning member is further lifted away from the cleaning surface in a limited height space, and the lifting effect is better.

[0057] Based on the above embodiment, please refer to Figures 6 to 12 , the driving assembly includes a driving shaft coaxially connected with the actuating member, and preferably, the driving shaft is key-connected with the actuating member. The driving shaft is further drivingly connected with the cleaning assembly. When the driving shaft rotates in the forward direction, the driving assembly drives the cleaning assembly to switch from the lifted state to the lowered state and drives the cleaning assembly to rotate. When the driving shaft rotates in the reverse direction, the driving assembly drives the cleaning assembly to switch from the lowered state to the lifted state. In this embodiment, the same driving assembly is used to realize the two functions of lifting the cleaning assembly and rotating the cleaning assembly, the overall structure of the cleaning device is more compact, the volume is smaller, and the production cost is reduced.

[0058] Specifically, please refer to Figure 4 and Figure 9 , the cleaning device further includes a one-way bearing and a transmission assembly. The one-way bearing is arranged in the housing, and preferably, is arranged in the housing. The transmission assembly is rotatably sleeved between the driving shaft and the one-way bearing, so that when the driving shaft rotates in the forward direction, the driving transmission assembly rotates coaxially. The cleaning assembly is linked with the transmission assembly, so that when the transmission assembly is driven to rotate, the cleaning assembly rotates coaxially with the transmission assembly. In this embodiment, the one-way bearing is used to realize the switching of different driving actions of the cleaning assembly by driving forward and reverse rotation. Specifically, when the driving shaft rotates in the forward direction, the driving shaft, the actuating member, the transmission assembly and the cleaning assembly all rotate coaxially. At this time, the cleaning assembly is driven to rotate in the lowered state and performs normal cleaning work. When the driving shaft rotates in the reverse direction, the transmission assembly and the cleaning assembly do not rotate with the driving shaft. The driving driving actuating member rotates relative to the cleaning assembly. The actuating member acts on the first end to lift the second end upward. After the cleaning assembly is switched to the lifted state, the driving shaft stops driving, and the cleaning assembly is kept in the lifted state. In this embodiment, the one-way bearing is used to realize the clutching between the driving shaft and the transmission assembly and the cleaning assembly. The structure is simple and reliable, and the occupied space is small.

[0059] The specific structure of the transmission assembly can be designed as needed. Please refer to Figures 6 to 12In the embodiment, the transmission assembly comprises an upper cover portion and a lower cover portion, the upper side of the upper cover portion is provided with a supporting ring inserted between the drive shafts of the one-way bearing, the lower cover portion covers the lower side of the upper cover portion to jointly enclose a mounting cavity, the peripheral side of the upper cover portion and / or the lower cover portion is provided with an opening communicating with the mounting cavity, the actuating member and the mounting ring are respectively sleeved on the outer periphery of the drive shaft and are arranged in the mounting cavity. Preferably, as shown in the drawings, the lower cover portion and / or the actuating member can also be provided with a radial support structure inserted in the mounting ring, so that the mounting ring is rotationally supported. The leg extends out of the mounting cavity from the opening, so that when the transmission assembly does not rotate with the drive shaft, it is relatively fixed with the shell, and the opening realizes the limiting in the circumferential direction of the mounting portion. When the transmission member rotates with the drive shaft, the opening realizes linkage between the leg, thereby driving the cleaning assembly to rotate around the drive shaft. In the embodiment, the transmission assembly plays a role in protecting, assembling the cleaning assembly and the actuating member. When the cleaning assembly needs to be replaced, the lower cover portion only needs to be disassembled, so that the assembly and replacement can be conveniently performed, the operation is simple, and especially for the cleaning member such as the side brush which is easily worn, the use experience of the user can be significantly improved. On the other hand, the transmission assembly also plays a role in limiting the circumferential direction of the mounting portion when the state of the cleaning assembly is switched, so that the mounting portion is deformed or displaced according to the preset requirement, the cleaning member is lifted, and when the cleaning assembly needs to be driven to rotate for cleaning work, the transmission assembly plays a transmission role, so that the rotating driving force of the drive shaft is transmitted to the cleaning member, and the cleaning member rotates under the driving of the drive shaft.

[0060] Further, optionally, referring to Figure 7 and Figure 11 , the lower side of the first section is recessed to form a limiting groove, the limiting groove is correspondingly clamped on the lower side of the opening and has a limiting surface abutting the outer side of the lower cover portion. It can be understood that the limiting groove can realize the limiting in the radial direction of the cleaning assembly and the upward supporting, so that the cleaning assembly is not easy to shake or be stuck in the radial direction when being driven to rotate. In addition, in the process that the cleaning assembly is switched from the lowered state to the lifted state, the limiting surface also plays a role in preventing the mounting portion from being excessively stretched into the mounting cavity, so as to reduce the risk that the mounting portion is stuck in the upper cover body and the lower cover body.

[0061] Optionally, the inner side of the upper cover portion is protruded with a protruding rib, the protruding rib abuts the first section in the rotating direction when the drive shaft rotates in the forward direction. Thus, in the process that the drive assembly is driven to rotate by the drive shaft, the rotating force is transmitted to the cleaning assembly by the actuating member in addition to the transmission assembly, the transmission efficiency is better, and the rotation of the cleaning assembly is more stable.

[0062] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or direct or indirect application in other related technical fields according to the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
