Description

Technical Field

[0002] Cleaning equipment, such as sweepers, sweeper-mop machines, floor scrubbers, etc., are increasingly used in modern households due to their good cleaning effects and cleaning efficiency. Cleaning equipment usually has a cleaning part for contacting and cleaning the cleaning surface. However, in different working modes, the cleaning part may need to be lifted to prevent it from contacting the cleaning surface. For example, the side brush of the cleaning equipment should contact the cleaning surface in the sweeping mode for cleaning. In mopping or other modes, it should be lifted to prevent the side brush from contacting the ground and causing secondary contamination. In addition, when the cleaning equipment is overcoming obstacles or cleaning corners, lifting the side brush can also reduce the chance of it being damaged by collision, thereby increasing the service life of the side brush.

[0003] However, the cleaning member lifting solutions in the prior art generally use an actuator that moves up and down to act on the cleaning member, resulting in the overall space occupied being too high when an ideal lifting effect of the cleaning member is to be achieved. This is difficult to achieve for the bottom side brush installed on the cleaning equipment. In addition, the structure of the side brush is complicated, resulting in increased production costs, and even significantly increased costs for users to replace the side brush.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The present invention provides a cleaning device and a cleaning apparatus 100 thereof. The specific form of the cleaning device is not limited, for example, it can be a handheld cleaning device, or a self-propelled cleaning device, etc. The cleaning device includes a body, and the cleaning apparatus 100 is suitable for being installed on the body of the cleaning device, preferably installed on the lower side of the body, so as to move with the body to clean the surface to be cleaned, wherein the cleaning device can be a sweeper, a mop, a sweeper and mop all-in-one machine, a floor scrubber, etc., and the surface to be cleaned can include but is not limited to the ground, wall, countertop, window, furniture surface, etc.

[0048] It can be understood that when the cleaning device is a self-propelled cleaning device, it can also include a walking drive mechanism for driving the body to automatically walk along the surface to be cleaned, and auxiliary walking parts such as rollers can also be installed on the body. The cleaning device 100 specifically includes a cleaning member 46, which refers to a member that directly contacts the surface to be cleaned to achieve friction cleaning of the surface to be cleaned. Its specific type depends on the specific type of the cleaning device, and the cleaning member can selectively contact or stay away from the cleaning surface according to the specific working scene of the cleaning device 100. For the convenience of explanation, in this embodiment, the cleaning member 46 can be a side brush, which is used to contact the cleaning surface for cleaning when the cleaning device is sweeping the floor, and when the cleaning surface is mopping or just walking or overcoming obstacles, the side brush can be lifted away from the cleaning surface to avoid secondary contamination of the cleaning surface and protect the side brush itself from being easily collided.

[0049] See also Figures 1 to 13 The present invention provides a cleaning device, which specifically includes a housing, a driving assembly, an actuator and a cleaning assembly, wherein the driving assembly is arranged in the housing, preferably arranged inside the housing. Figure 4 As shown, the driving assembly should specifically include a motor, a reduction mechanism and a driving shaft. The motor is connected to the driving shaft through the reduction mechanism to drive the driving shaft to rotate. The specific structure of the reduction mechanism is not limited. In this embodiment, the reduction mechanism includes a multi-stage reduction gear. It should be noted that in this embodiment, the positive rotation can be one of the clockwise and counterclockwise rotations of the driving shaft, and the reverse rotation refers to the rotation of the driving shaft in the opposite direction to the positive direction.

[0050] Please refer to Figure 4 and Figures 6 to 13 , the actuator is rotatably arranged relative to the shell, and the driving assembly is drivingly connected to the actuator to drive the actuator to rotate. The cleaning assembly is also rotatably arranged relative to the shell, and includes the cleaning member mentioned above. Specifically, the cleaning assembly has a first end relatively close to the actuator, and a second end relatively far away from the actuator, and preferably, the end of the cleaning member can constitute the second end. When the cleaning assembly rotates, the second end rotates around the outer circumference of the first end, and the cleaning assembly has a lifting state in which the second end is relatively close to the first end in the up-down direction, and a descending state in which the second end is relatively far away from the first end in the up-down direction.

[0051] In this embodiment, during the active stroke in which the driving assembly drives the actuator to rotate, the actuator acts on the first end so that the cleaning assembly switches between the raised state and the lowered state. Specifically, when the cleaning assembly needs to use the cleaning member for cleaning, such as in the sweeping mode of the cleaning device, the actuator can be used to act on the first end during its rotation stroke so that the second end descends to contact the cleaning surface, and the cleaning assembly rotates normally for cleaning. When the cleaning assembly does not need to use the cleaning member for cleaning, such as in the walking mode, the mopping mode, etc., the actuator can be used to act on the first end again so that the second end is lifted away from the cleaning surface, and the cleaning assembly does not rotate for cleaning. In the present invention, the cleaning device uses a rotating actuator to actuate the cleaning assembly. Compared with the actuator that moves up and down, it requires less space and does not require a complex transmission mechanism to connect the motor. It can effectively compress the overall size of the cleaning device in the up and down directions. The structure is simple and easy to maintain, and it is not prone to failure, which reduces the maintenance cost of the cleaning device.

[0052] For further information, see Figure 6 and Fig.10 , the cleaning assembly includes a mounting portion and a cleaning member. In this example, the cleaning member can be a side brush bundle including multiple bristles, or other material structures with a cleaning effect, such as a rubber strip. The mounting portion is used to fix the side brush bundle, which can be made of resin, rubber, silicone, etc., and the cleaning member is preferably insert-molded in the mounting portion. In this way, the cleaning assembly as a whole constitutes a replaceable consumable component. The mounting portion at least partially constitutes the first end, the cleaning member is fixed to the mounting portion, and the end of the cleaning member away from the mounting portion constitutes the second end. In the process of the actuator acting on the first end, the mounting portion at least partially displaces and / or elastically deforms, so that the second end is relatively close to or away from the first end in the up and down direction. Specifically, the mounting member can be a rigid material, and the displacement of the mounting member makes the second end move up and down. The mounting member can also include an elastic material, and the elastic deformation of the mounting member makes the second end move up and down. In a preferred embodiment, a part of the structure of the mounting portion has both displacement and elastic deformation under the action of the actuator, and then drives the cleaning member to move, so that its second end rises and moves away from the cleaning surface. In this way, on the one hand, the cleaning member is sufficiently lifted away from the cleaning surface, and on the other hand, the elastic deformation of the actuator itself is used to drive the cleaning member to be lifted. The required space is small, and the cleaning member does not need to be installed by rotating fixation, etc., which facilitates assembly and replacement. The elasticity of the actuator can also be used to more firmly keep the cleaning component in the lifted state.

[0053] Best, please continue reading Figure 6 and Fig.10The mounting portion includes a mounting ring and a support leg extending from the mounting ring to the periphery, and the mounting ring is preferably integrally arranged with the support leg. The support leg includes a first section and a second section which are sequentially connected and arranged at an angle in a direction away from the mounting ring, the first section constitutes a first end, the second section is bent downward relative to the first section and extends, and the cleaning member is fixed to the second section. In the process of the cleaning component switching from the lowered state to the raised state, the actuator acts on the first section so that the first section is pressed down, and the second section is tilted upward, driving the second end to rotate upward. In this embodiment, the downward bending structure of the support leg itself is utilized, so that when the first section is pressed down under the action of the actuation element, the second section is tilted like a lever. In this way, not only does the cleaning component have a very simple and easy-to-replace structure, but also the second end has a larger displacement in the up and down directions in a smaller space, and the lifting effect of the cleaning member is good.

[0054] Preferably, a plurality of supporting feet are provided, and the plurality of supporting feet are distributed at intervals along the circumference of the mounting ring.

[0055] Specifically, see Figures 6 to 9 In the first embodiment provided by the present invention, the actuator has a guide bevel arranged downward. It can be understood that when a plurality of legs are provided, a plurality of guide bevels should also be provided at intervals along the circumferential direction. The guide bevel extends downwardly in the circumferential direction and is correspondingly arranged above the first section. In this embodiment, when the cleaning assembly switches from a descending state to a lifting state, while the actuator rotates, the guide bevels abut against the upper side of the first section one by one to gradually press down the first section, so that the second section tilts upward, driving the second end of the cleaning member to rotate up and down away from the cleaning surface. In this way, the actuator has a simple and reliable structure, and within the limited space size in the up and down directions, the cleaning member has a sufficient lifting effect.

[0056] In the second embodiment provided by the present invention, please refer to Figures 10 to 13 , the actuator includes a guide key protruding toward the outer circumference. It can be understood that when a plurality of legs are provided, a plurality of guide keys should also be provided at intervals along the circumferential direction. The protruding height of the guide key gradually changes along the circumference. An action key is correspondingly provided on the lower side of the first section. During the rotation stroke of the actuator, the guide key pushes the action key outward, so that the first section is deformed and pressed down. In this embodiment, during the process of the cleaning component switching from the descending state to the lifting state, while the actuator rotates, the guide slopes correspond one by one to the upper side of the first section, so as to gradually press down the first section, so that the second section tilts upward, driving the second end of the cleaning member to rotate up and down away from the cleaning surface. In this way, the actuator has a simple and reliable structure, and within the limited space size in the up and down directions, the cleaning member has a sufficient lifting effect.

[0057] Based on the above examples, please continue to refer to Figure 6 and Fig.10The cleaning member is extended along the first direction toward the second end, and the second section is deflected relative to the first section around the first direction, so that when the cleaning component switches from the lowered state to the raised state, the cleaning member also generates a twisting motion rotating around the first direction. In this way, when the cleaning member is in the lowered state, its second end is in line contact with the cleaning surface, with a large contact area and a good cleaning effect. When the cleaning member switches to the raised state, in addition to rotating upward relative to the first end, the second end also undergoes a certain degree of twisting, which further makes the cleaning member away from the cleaning surface within a limited height space, and the lifting effect is better.

[0058] Based on the above embodiments, please refer to Figures 6 to 13 The driving assembly includes a driving shaft coaxially connected to the actuator, and preferably, the driving shaft is key-connected to the actuator. The driving shaft is also drivingly connected to the cleaning assembly. When the driving shaft rotates forward, the driving assembly drives the cleaning assembly to switch from the raised state to the lowered state and drives the cleaning assembly to rotate. When the driving shaft rotates reversely, the driving assembly drives the cleaning assembly to switch from the lowered state to the raised state. In this embodiment, the same driving assembly is used to realize the two functions of lifting the cleaning assembly and driving the rotation of the cleaning assembly. The overall structure of the cleaning device is more compact and smaller, and its production cost is reduced.

[0059] For details, please refer to Figure 4 and Fig. 9 The cleaning device further comprises a one-way bearing and a transmission assembly, wherein the one-way bearing is arranged on the housing, preferably, arranged in the housing, and the transmission assembly is rotatably sleeved between the drive shaft and the one-way bearing, so that when the drive shaft rotates in the forward direction, the drive transmission assembly rotates coaxially, and the cleaning assembly is arranged in linkage 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 drive shaft rotates in the forward direction, the drive shaft, the actuator, the transmission assembly and the cleaning assembly all rotate coaxially. At this time, the cleaning assembly is driven to rotate in the descending state and performs normal cleaning work. When the drive shaft rotates in the reverse direction, the transmission assembly and the cleaning assembly no longer rotate with the drive shaft, and the driving actuator rotates relative to the cleaning assembly. The actuator acts on the first end, so that the second end is lifted upward. After the cleaning assembly is switched to the lifting state, the drive shaft stops driving, and the cleaning assembly is kept in the lifting state. In this embodiment, the one-way bearing is used to realize the clutch between the drive shaft, the transmission assembly and the cleaning assembly, and the structure is simple and reliable, and the space occupied is small.

[0060] The specific structure of the transmission assembly can be designed according to needs, please continue to refer to Figures 6 to 13In this embodiment, the transmission assembly includes an upper cover and a lower cover, the upper side of the upper cover is provided with a support ring inserted between the one-way bearing drive shaft, the lower cover is covered on the lower side of the upper cover to form a mounting cavity together, the upper cover and / or the lower cover are provided with an opening connected to the mounting cavity on the circumference, the actuator and the mounting ring are respectively sleeved on the outer periphery of the drive shaft, and are both arranged in the mounting cavity. Preferably, as shown in the figure, the lower cover and / or the actuator can also be provided with a radial support structure inserted in the mounting ring so that the mounting ring is supported by rotation. The support 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 housing, and the opening realizes the circumferential limit of the mounting portion. When the transmission member rotates with the drive shaft, the opening realizes the linkage with the support leg, thereby driving the cleaning assembly to rotate around the drive shaft. In this embodiment, the transmission assembly plays a role in protecting and assembling the cleaning assembly and the actuator. When the cleaning assembly needs to be replaced, only the lower cover part needs to be disassembled to conveniently assemble and replace it. The operation is simple and convenient, especially for easily worn cleaning parts such as side brushes, which can significantly improve the user experience. On the other hand, it also plays a role in limiting the circumferential position of the mounting part when the state of the cleaning assembly is switched, so that it deforms or displaces according to the preset requirements, driving the cleaning part to rise. When the cleaning assembly needs to be driven to rotate for cleaning, the transmission assembly plays a transmission role, so that the rotational driving force of the drive shaft is transmitted to the cleaning part, and the cleaning part rotates under the drive of the drive shaft.

[0061] Further, optionally, see Figure 7 and Fig.11 The lower side of the first section is concavely provided with a limiting groove, which is correspondingly engaged with the lower side of the opening and has a limiting surface that abuts against the outer side of the lower cover. It can be understood that the limiting groove can achieve radial limiting and upward support of the cleaning component, so that the cleaning component is not prone to radial shaking or jamming when driven to rotate. In addition, when the cleaning component switches from a lowered state to a raised state, the limiting surface prevents the mounting portion from being excessively stretched into the mounting cavity, thereby reducing the risk of the mounting portion being jammed in the upper cover body and the lower cover body.

[0062] Optionally, a convex rib is provided on the inner side of the upper cover, and when the drive shaft rotates in the forward direction, the convex rib abuts against the first section in the rotation direction. In this way, when the drive assembly is driven to rotate by the drive shaft, in addition to the transmission assembly, the actuator also transmits the rotational force to the cleaning assembly, so that the transmission efficiency is better and the rotation of the cleaning assembly is smoother.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
