Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, in particular to a shearing structure and cleaning equipment. Background Art

[0002] Cleaning robots currently on the market often have hair entangled in their brushes after cleaning a home, requiring the user to manually clean the brush. Existing hair-cutting mechanisms require a separate motor to power the cutting mechanism to cut the hair. Both the motor and the cutting mechanism occupy a significant amount of space within the cleaning robot, reducing its internal space utilization. Summary of the Invention

[0003] Based on this, it is necessary to provide a shearing structure and cleaning equipment to address the problems that the cutting structure of the above-mentioned cleaning equipment is complex and occupies a lot of space.

[0004] A shearing structure includes a mounting assembly and a shearing assembly, wherein the mounting assembly is used to be movably mounted on the body of a cleaning device and to mount a roller brush, and the direction in which the mounting assembly moves toward the body is a first direction; the shearing assembly is movably arranged on the mounting assembly, and the direction in which the shearing assembly moves toward the roller brush is a second direction, and the second direction intersects with the first direction. When the mounting assembly moves along the first direction, it drives the shearing assembly to move along the second direction, so that the shearing assembly can perform shearing operations.

[0005] In one embodiment, a shearing groove is formed on the mounting assembly, and the shearing groove is used to accommodate hair. The shearing assembly includes a resistance member and a shearing member. The resistance member can be movably set on the mounting assembly, and the shearing member is set on the resistance member and is located in the shearing groove. The resistance member is used to resist the fuselage when the mounting assembly moves along the first direction, and push the shearing member to move along the second direction toward a side wall in the shearing groove, so that the shearing assembly can perform shearing operations.

[0006] In one embodiment, the shearing assembly further includes a reset member, which is mounted on the mounting assembly. The reset member can be elastically deformed when subjected to force, and the reset member abuts against the resisting member. The reset member can apply an elastic force opposite to the second direction to the resisting member.

[0007] In one embodiment, the reset member is a spring arm structure. There are at least two reset members, each of which is located on either side of the abutment member in the second direction. One end of each reset member is mounted on the mounting assembly, and the other end of each reset member abuts against the abutment member.

[0008] In one embodiment, a movable groove is formed on the resistance member, and the other end of the reset member is in resistance against the inner wall of the movable groove. When the reset member is elastically deformed under force, the other end of the reset member can move on the inner wall of the movable groove, and the moving direction of the other end of the reset member intersects with the first direction.

[0009] A cleaning device comprises a body, a roller brush and the shearing structure as described above, wherein the mounting assembly can be movably mounted on the body; the roller brush is mounted on the mounting assembly.

[0010] In one embodiment, an inclined surface is formed on the fuselage, and the inclined surface can intersect with both the first direction and the second direction. The angle between the inclined surface and the second direction is non-right angle. The movement of the mounting component along the first direction can drive the shearing component to contact the inclined surface, and the inclined surface can push the shearing component to move along the second direction.

[0011] In one embodiment, a mounting cavity is formed on the fuselage, the mounting assembly is movably disposed in the mounting cavity, an inner wall on one side of the mounting cavity is the inclined surface, and the shearing assembly is disposed opposite to the inclined surface.

[0012] In one embodiment, the cleaning device also includes a roller brush, which is rotatably mounted on the mounting assembly, and the rotation axis of the roller brush is consistent with the second direction. The rotation of the roller brush can cause the hair on the roller brush to move toward the shearing assembly and be located on the moving route of the shearing assembly.

[0013] In one embodiment, the rotation direction of the roller brush is a third direction, the roller brush is provided with a blade portion, the blade portion is spirally arranged on the outer surface of the roller brush, the rotation direction of the blade portion is a fourth direction, and the fourth direction is opposite to the third direction.

[0014] In one embodiment, the number of the blade portions is at least two, two adjacent blade portions are spaced apart on the outer surface of the roller brush, and the spiral direction of each blade portion is the fourth direction.

[0015] In the above-mentioned shearing structure and cleaning device, the mounting assembly can be installed with a roller brush, and the mounting assembly can be movably set on the body along a first direction. The roller brush accumulates hair during use. When the cleaning device vibrates during operation, causing the mounting assembly to move along the first direction, it can drive the shearing assembly to move along the second direction, thereby allowing the shearing assembly to perform a shearing operation to cut off the hair located in the second direction. This thereby achieves the cleaning of the hair on the drum. The shearing structure does not require an additional motor drive to perform the shearing operation. During the operation of the cleaning device, the hair can be cleaned by vibrating in the first direction, thereby ensuring the ease of use and reliability of the shearing structure. It is also obvious that the shearing structure is simple and does not occupy too much internal space of the cleaning device, further ensuring the rationality of the design of the shearing structure.

[0024] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See Figure 1 、 Figure 2 and Figure 4 The cleaning device 10 in one embodiment includes a body 100, a shearing structure 200, and a roller brush 300. The shearing structure 200 includes a mounting assembly 210 and a shearing assembly 220. The mounting assembly 210 is used to be movably mounted on the body 100 of the cleaning device 10 and is used to mount the roller brush 300. The direction in which the mounting assembly 210 moves toward the body 100 is a first direction A. The shearing assembly 220 is movably arranged on the mounting assembly 210. The direction in which the shearing assembly 220 moves toward the roller brush 300 is a second direction B. The second direction B intersects with the first direction A. When the mounting assembly 210 moves along the first direction A, it drives the shearing assembly 220 to move along the second direction B, so that the shearing assembly 220 can perform a shearing operation.

[0026] The mounting assembly 210 can be installed with a roller brush, and the mounting assembly 210 can be movably arranged on the body 100 along the first direction A. The roller brush accumulates hair during use. When the cleaning device 10 vibrates during operation, causing the mounting assembly 210 to move along the first direction A, it can drive the shearing assembly 220 to move along the second direction B, thereby allowing the shearing assembly 220 to perform a shearing operation to cut off the hair located in the second direction B. This thereby achieves the cleaning of the hair on the drum. The shearing structure 200 does not require an additional motor drive to achieve the shearing operation. During the operation of the cleaning device 10, the hair can be cleaned by shaking in the first direction A, thereby ensuring the ease of use and reliability of the shearing structure 200. It is also obvious that the shearing structure 200 is simple and does not occupy too much internal space of the cleaning device 10, further ensuring the rationality of the design of the shearing structure 200.

[0027] See Figure 1 and Figure 2In one embodiment, the body 100 is formed with an inclined surface 110. The inclined surface 110 intersects both the first direction A and the second direction B. The angle between the inclined surface 110 and the second direction B is non-perpendicular. Movement of the mounting assembly 210 in the first direction A causes the shearing assembly 220 to come into contact with the inclined surface 110, which in turn propels the shearing assembly 220 in the second direction B. During movement, vibrations generated by the cleaning device 10 cause the mounting assembly 210 to move in the first direction A. At this point, the mounting assembly 210 can move in the first direction A, causing the shearing assembly 220 to come into contact with the inclined surface 110 and continue to move along the inclined surface 110. Because the inclined surface 110 intersects both the first direction A and the second direction B, it applies a thrust to the shearing assembly 220 in the second direction B, thereby enabling the shearing assembly 220 to move in the second direction B and perform a shearing operation. By providing an inclined surface 110 that intersects both the first direction A and the second direction B, and utilizing the movement of the cleaning device 10 to generate a force in the first direction A, the shearing assembly 220 is ensured to complete the shearing operation in the second direction B. Clearly, the shearing structure 200 is concise and ingeniously designed, and does not occupy excessive internal space of the cleaning device 10, thereby ensuring the rationality of the design of the internal structure of the cleaning device 10, as well as the rationality and reliability of the design of the shearing structure 200.

[0028] See Figure 1 and Figure 2 In one embodiment, a mounting cavity 120 is formed on the housing 100, and the mounting assembly 210 is movably disposed within the mounting cavity 120. One inner wall of the mounting cavity 120 is an inclined surface 110, and the shearing assembly 220 is disposed opposite the inclined surface 110. The mounting cavity 120 provides a stable structural environment for the mounting assembly 210, ensuring that after the mounting assembly 210 moves in the first direction A, the shearing assembly 220 can stably complete the shearing operation in the second direction B. This further ensures the structural rationality and practicality of the cleaning device 10.

[0029] See Figures 1 to 3 In one embodiment, the cleaning device 10 further includes a roller brush 300 rotatably mounted on the mounting assembly 210. The rotation axis of the roller brush 300 is aligned with the second direction B. Rotation of the roller brush 300 causes hair on the roller brush 300 to move toward the shear assembly 220 and into the shear assembly 220's path. Rotation of the roller brush 300 gathers hair toward the shear assembly 220, facilitating hair severing by the shear assembly 220 during the shearing operation. The hair-gathering effect of the rotation of the roller brush 300 further improves the structural efficiency and practicality of the shear mechanism 200.

[0030] See Figure 2 and Figure 3In one embodiment, the roller brush 300 rotates in a third direction, and is provided with blades 310. The blades 310 are spirally disposed on the outer surface of the roller brush 300, and the blades 310 rotate in a fourth direction, which is opposite to the third direction. This arrangement allows hair to be better gathered, facilitating hair shearing by the shearing assembly 220.

[0031] In one embodiment, there are at least two blade portions 310, with adjacent blade portions 310 spaced apart on the outer surface of the roller brush 300, and each blade portion 310 spiraling in the fourth direction. Multiple blade portions 310 can further improve cleaning efficiency and ensure more efficient hair collection.

[0032] See Figures 2 to 4 In one embodiment, a shearing groove 211 is formed on the mounting assembly 210 for accommodating hair. The shearing groove 211 is configured to receive hair. The shearing assembly 220 includes a resisting member 221 and a shearing member 222. The resisting member 221 is movably mounted on the mounting assembly 210, while the shearing member 222 is mounted on the resisting member 221 and positioned within the shearing groove 211. The resisting member 221 is configured to abut against the body 100 when the mounting assembly 210 moves in a first direction A, pushing the shearing member 222 in a second direction B toward a sidewall within the shearing groove 211, thereby enabling the shearing assembly 220 to perform a shearing operation. When the roller brush 300 rotates to gather hair, the hair is attracted to the side of the shearing groove 211 and eventually falls into the shearing groove 211. The shearing member 222 moves in the second direction B within the shearing groove 211 and abuts against an inner wall of the shearing groove 211, thereby shearing the hair. It should be noted that when the roller brush gathers hair, the hair is wrapped around the circumferential direction of the roller brush and falls into the shear groove 211. The length direction of the hair must intersect with the second direction B, and the shearing piece 222 can also cut the hair along the second direction B.

[0033] In one embodiment, the mounting assembly 210 includes a connector and a mounting member. The connector and the mounting member are connected. The roller brush 300 is rotatably mounted on the connector. The shearing assembly 220 is movably mounted on the mounting member along a second direction B. The connector is provided with a shearing groove 211.

[0034] See Figure 3 and Figure 4In one embodiment, the shear assembly 220 further includes a reset member 223 mounted on the mounting assembly 210. The reset member 223 is elastically deformed when subjected to force. The reset member 223 contacts the resisting member 221 and applies an elastic force to the resisting member 221 in the opposite direction B. The reset member 223 can push the resisting member 221 back to its original position through elastic deformation, further ensuring the reliability of the shear structure 200.

[0035] In one embodiment, the reset member 223 is an elastic arm structure. There are at least two reset members 223, and the at least two reset members 223 are respectively located on both sides of the interference member 221 in the second direction B. One end of each reset member 223 is mounted on the mounting assembly 210, and the other end of each reset member 223 abuts against the interference member 221. At least two elastic arms are spaced apart, and the interference member 221 is located between the two elastic arms. The two elastic arms can simultaneously apply a reset force to the interference member 221 from both sides of the interference member 221, ensuring the movement stability of the interference member 221 during the reset process, thereby improving the reliability of the shear structure 200.

[0036] In one embodiment, a movable groove 224 is formed in the abutment member 221. The other end of the reset member 223 abuts against the inner wall of the movable groove 224. When the reset member 223 is elastically deformed under force, the other end of the reset member 223 can move along the inner wall of the movable groove 224, with the movement direction of the other end of the reset member 223 intersecting the first direction. The movement of the other end of the reset member 223 within the movable groove 224 ensures the stability of the deformation and movement of the reset member 223 after deformation. This, in turn, ensures the stability of the reset of the abutment member 221 and the practicality and reliability of the shear structure 200.

[0037] In one embodiment, the number of movable grooves 224 corresponds to the number of reset members 223. Each reset member 223 abuts against the inner wall of a movable groove 224. Preferably, at least two movable grooves 224 are provided on either side of the abutting member 221 in the second direction B, thereby ensuring balanced force on the abutting member 221 and further ensuring the practicality of the shear structure 200.
