Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] refer to Figures 1 to 4 A wheel 1 anti-winding mechanism 100 includes a wheel 1 and an anti-winding component 2. The anti-winding component 2 is used to prevent or reduce the wrapping of fabric or the like onto the wheel 1.

[0018] refer to Figure 3 and Figure 4 The wheel 1 is rotatable, for example, driven to rotate by a motor 3. Viewed horizontally, the wheel 1 can be divided into an upper half 11 and a lower half 12 by line AB, where line AB is a horizontal line passing through the center of the wheel 1.

[0019] The anti-entanglement component 2 includes a blocking part 21, which is non-rotatable and located on one side of the wheel 1; for example, the blocking part 21 is fixed. Thus, the anti-entanglement component 2 and the wheel 1 are configured to rotate relative to each other. The blocking part 21 can be positioned as close to the wheel as possible.

[0020] refer to Figure 3 At least a portion of the blocking portion 21 corresponds to the lower half 12 region of the wheel 1; that is, from the horizontal projection direction, at least a portion of the blocking portion 21 corresponds to the lower half 12 region of the wheel 1, that is, at least a portion of the blocking portion 21 is within the lower half 12 region of the wheel 1; for example, the blocking portion 21 may have a partial structure that corresponds to the lower half 12 of the wheel 1, or it may have a complete structure that corresponds to the lower half 12 of the wheel 1.

[0021] The lowest point D of the blocking part 21 in the vertical direction is higher than the lowest point C of the wheel 1. This can be understood as follows: the lowest point C of the wheel 1 is the point of contact with the running surface, which can be a bed or the ground, etc. Since the lowest point D of the blocking part 21 is higher than the lowest point C of the wheel 1 in the vertical direction, the blocking part 21 does not obstruct the wheel 1 from contacting the running surface and does not obstruct the wheel 1 from moving.

[0022] Therefore, when the wheel 1 travels on the travel surface, the blocking part 21 of the anti-entanglement part 2 can block or reduce the contact between the fabric and the wheel 1, thereby preventing the fabric from entangled or wrapped around the wheel 1 to a certain extent, so that the wheel 1 can travel smoothly.

[0023] For example, when walking on the bed, the blocking part 21 can prevent the sheets or duvet covers from getting tangled or wrapped around the wheel 1 to a certain extent, thus making it easier to walk on the bed.

[0024] For example, when walking on the ground, there is some cloth on the ground. The blocking part 21 can prevent the cloth from getting tangled or wrapped around the wheel 1 to a certain extent, so that the wheel 1 can walk smoothly.

[0025] refer to Figures 6 to 14 The blocking part 21 is circular, semi-circular, fan-shaped, arc-shaped, semi-arc-shaped, or inferior arc-shaped; the inferior arc-shaped is a fan-shaped ring or a ring that defines a certain angle.

[0026] When the blocking part 21 is circular or arc-shaped, at least the bottom of the blocking part 21 corresponds to the lower half 12 of the wheel 1.

[0027] When the blocking part 21 is semi-circular, semi-circular arc-shaped or fan-shaped, the bottom of the blocking part 21 can correspond to the lower half 12 of the wheel 1, or the entire blocking part 21 can correspond to the lower half 12 of the wheel 1.

[0028] When the blocking part 21 is semi-circular, semi-circular, fan-shaped, or slightly curved, the blocking part 21 is provided to extend downward; for example, it can be provided to extend vertically downward or to extend obliquely downward.

[0029] refer to Figure 7 and Figure 8 When the blocking part 21 is arc-shaped, the ring 213 of the blocking part 21 can be a continuous structure or a discontinuous structure.

[0030] refer to Figure 10 and Figure 11 When the blocking part 21 is semi-circular, the ring 213 of the blocking part 21 can be a continuous structure or a discontinuous structure.

[0031] refer to Figure 13 and 14 When the blocking part 21 is in the shape of a slight arc, the ring body 213 of the blocking part 21 can be a continuous structure or a discontinuous structure.

[0032] Of course, circular or semi-circular blocking parts 21 can cover a larger area of ​​the side of the wheel 1, resulting in a better anti-winding effect.

[0033] The blocking part 21 is coaxially arranged with the wheel 1. Of course, it can also be offset.

[0034] When coaxially arranged, the radius of the blocking part 21 is smaller than the radius of the wheel 1, so that the blocking part 21 does not protrude from the outer circumferential surface of the wheel 1.

[0035] The ratio of the radius of the blocking part 21 to the radius of the wheel 1 is between 80% and 95%. This allows for large-area coverage of the side of the wheel 1, more effectively preventing fabrics from wrapping around or covering the wheel 1, resulting in better anti-winding performance.

[0036] refer to Figure 5 The blocking part 21 includes a first wall surface 211 and a surrounding edge 212. The surrounding edge 212 is disposed along the edge of the first wall surface 211 and extends close to the wheel 1. Therefore, the surrounding edge 212 allows the blocking part 21 to be closer to the wheel 1, reducing the gap between them and making it less likely for the fabric to entangle or cover the wheel 1. Furthermore, the close proximity of the surrounding edge 212 to the wheel 1 also helps to reduce contact between the blocking part 21 and the wheel 1, thus minimizing any impact on the rotation of the wheel 1.

[0037] When the blocking part 21 is circular, semi-circular or fan-shaped, the first wall surface 211 has a corresponding circular, semi-circular or fan-shaped structure; of course, the first wall surface 211 may also have a hollow structure such as through holes. When the blocking part 21 is arc-shaped, semi-circular, or slightly curved, the first wall surface 211 has a hollow structure, and the edge of the first wall surface 211 forms a ring 213. For example, the first wall surface 211 has multiple connecting strips radiating outward, connecting the ring 213 to the assembly part 22. The ring 213 has a corresponding perimeter 212. The ring 213 can be a continuous structure or a discontinuous structure.

[0038] refer to Figure 2 The anti-tangling component 2 includes an assembly part 22, which is coaxially arranged with the blocking part 21, or the assembly part 22 is located in the middle of the blocking part 21. The assembly part 22 can be connected to a preset position by fasteners such as screws, thereby realizing the fixing or assembly of the anti-tangling component 2. The assembly part 22 may be cylindrical.

[0039] Optionally, both sides of the wheel 1 may be provided with blocking parts 21. Thus, both sides of the wheel 1 are covered with blocking parts 21, which further prevents fabric or the like from wrapping around or covering the wheel 1, thereby further improving the anti-winding effect.

[0040] refer to Figures 16 to 20A mite-removing cleaning robot 300 is available, capable of cleaning beds and other surfaces.

[0041] The mite-removing cleaning robot 300 includes an anti-tangling mechanism 100 and a housing 310; The wheel 1 is assembled on the housing 310, and the motor 3 can be located inside the housing 310. The motor 3 is connected to the wheel 1 for driving. The anti-entanglement component 2 is located between the wheel 1 and the housing 310. For example, the blocking part 21 of the anti-entanglement component 2 is located between the inner side of the wheel 1 and the first side wall 320 of the housing 310.

[0042] The inner side of the wheel 1 is provided with a blocking part 21, which can prevent bed sheets or duvet covers from getting tangled or wrapped around the wheel 1. Furthermore, there is a gap between the inner side of the wheel 1 and the first wall 211 of the outer casing 310. The blocking part 21 is disposed in this gap, which is equivalent to filling the gap or reducing the space of the gap, making it difficult for the fabric to enter the gap and wrap around or cover the wheel 1. This also makes the blocking part 21 a certain degree of concealment, improving the aesthetics.

[0043] refer to Figure 15 and Figure 18 The inclination of the first wall surface 211 of the blocking part 21 matches the inclination of the first side wall 320. As a result, the blocking part 21 is closer to or fits closer to the outer casing 310, allowing the blocking part 21 to better fill the gap.

[0044] refer to Figure 2 and Figure 19 The anti-tangling component 2 includes an assembly part 22, which is coaxially arranged with the blocking part 21, or the assembly part 22 is located in the middle of the blocking part 21. The assembly part 22 is connected to the housing 310, for example, by fasteners such as screws. The assembly part 22 is sleeved or covered on the motor 3, and the assembly part 22 may have a cylindrical structure. Thus, the assembly part 22 not only fixes the blocking part 21, but also provides a certain limitation on the motor 3.

[0045] Optionally, both the inner and outer sides of the wheel 1 are provided with blocking parts 21. Thus, both sides of the wheel 1 are covered with blocking parts 21, further preventing the fabric from wrapping around or covering the wheel 1, and further improving the anti-winding effect.

[0046] refer to Figure 20 The mite-removing cleaning robot 300 is also equipped with a roller brush 330 and a mite-removing component 340, both of which are located on the lower surface or bottom of the outer shell 310.

[0047] The mite removal device 340 can be a device that generates mite removal functions such as ultraviolet light, ultrasonic waves or high-voltage electric shock.

[0048] The above description only discloses some embodiments of the present invention. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the invention.
