Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment accessories, in particular to a roller brush component for preventing hair from winding. Background Art

[0002] In recent years, with the improvement of people's living standards, home cleaning has gradually entered an era of automation and intelligence. The cleaning equipment that has emerged can liberate people from home cleaning work, effectively reduce people's workload in home cleaning, and alleviate people's fatigue during home cleaning.

[0003] Usually, the cleaning device includes a body and a roller brush, and the roller brush is rotatably arranged in the body under the drive of a driving mechanism. When the cleaning device is working, the roller brush can collect dust, hair and other garbage on the surface to be cleaned during the rotation process, thereby completing the cleaning of the surface to be cleaned. During the operation of the roller brush, the hair is easily entangled on the outer peripheral surface of the roller brush, which brings inconvenience to the cleaning work of the roller brush. If a blade is installed on the body to cut the hair entangled on the surface of the roller brush, the actual cleaning effect of the hair is not ideal because the blade is difficult to cut the fluffy and soft hair.

[0004] In the prior art, a single roller brush with a free end is provided, and the free end of the roller brush points to the suction port, so that the hair is sucked into the suction port, thereby preventing the hair from being entangled on the roller brush. However, the roller brush in the prior art has the following disadvantages: the roller brush structure and the suction port are both vertically arranged, so that the negative pressure can only act on the end of the roller brush. The hair located at a position of the roller brush far away from the free end has insufficient adsorption force, which is not conducive to the entry of the hair. Summary of the invention

[0005] In order to solve the above problems, the utility model provides a hair-tangle-proof roller brush assembly, which is inclined toward the dust suction channel. When the suction device is working, the negative pressure generated can act more effectively on the roller brush surface, thereby enhancing the adsorption of dust, hair and other garbage. This design enables the roller brush to more easily push garbage to the suction port during rotation, thereby improving cleaning efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a hair entanglement prevention roller brush assembly, comprising: a roller brush bin, two roller brushes, the roller brush bin is provided with a dust suction channel for connecting to a suction device, and the end of the dust suction channel is provided with a suction port connected to the roller brush bin, wherein each roller brush comprises a fixed end and a free end, the fixed ends of the two roller brushes are movably mounted on both sides of the roller brush bin, and the free ends of the roller brushes are suspended and face the suction port, and the central axis of the roller brush and the central axis of the dust suction channel have an angle A, wherein the value range of A is 90° <A<180°。

[0007] Furthermore, the roller brush includes a roller brush shaft and a brush body disposed on the outer circumferential surface of the roller brush shaft, and the brush body is spirally disposed around the circumference of the roller brush body.

[0008] Furthermore, the two roller brushes are respectively a first roller brush and a second roller brush, the first roller brush and the second roller brush are symmetrically arranged inside the roller brush bin, and a gap arranged opposite to the suction port is reserved between the free ends of the first roller brush and the second roller brush.

[0009] Furthermore, the two roller brushes are respectively a first roller brush and a second roller brush, and the free end of the first roller brush is located in front of the free end of the second roller brush.

[0010] Furthermore, the free end of the first roller brush and the free end of the second roller brush are both located on a vertical plane of the central axis of the dust suction channel.

[0011] Further, the free end of the first roller brush or the free end of the second roller brush passes through the vertical plane of the central axis of the dust suction channel.

[0012] The beneficial effects of the utility model are:

[0013] Enhanced adsorption: Since the roller brush is tilted toward the dust suction channel (and the angle between the roller brush and the dust suction channel is kept at an obtuse angle), when the suction device is working, the negative pressure generated can act more effectively on the roller brush surface, thereby enhancing the adsorption of dust, hair and other garbage. This design allows the roller brush to push garbage to the suction port more easily during rotation, improving cleaning efficiency.

[0014] Reduce hair entanglement: When the hair on the roller brush surface needs to be sucked into the dust suction channel, the hair needs to turn an obtuse angle because the roller brush is inclined toward the dust suction channel. Compared with a right-angle or sharp-angled curve, this design is more conducive to the hair entering the dust suction channel smoothly and reduces the hair entanglement on the roller brush.

[0015] Improved cleaning effect: Since the roller brush is tilted towards the dust collection channel, it can better fit the surface to be cleaned during rotation, thereby collecting garbage more comprehensively. At the same time, due to the enhanced adsorption force and reduced hair entanglement, the cleaning device can clean the surface to be cleaned more thoroughly, improving the cleaning effect.

[0021] See also Figure 1 As shown, this embodiment provides a cleaning device 1, which mainly includes a suction device and a roller brush assembly connected to the suction device. The suction device is used to generate negative pressure to remove dust and other garbage entering from the roller brush assembly. The roller brush assembly includes a roller brush bin 2 and a roller brush arranged in the roller brush bin 2. The roller brush bin 2 has a dust suction port 21 facing the surface to be cleaned. The roller brush is used to contact the surface to be cleaned and rotate on the surface to be cleaned, so that when the cleaning device 1 moves along the surface to be cleaned, the dust, hair and other garbage on the surface to be cleaned are collected toward the inside of the dust suction port 21. The roller brush bin 2 is connected to the suction device, and the suction device is used to draw negative pressure on the roller brush bin 2. With the rotation of the roller brush, the garbage at the dust suction port 21 can be sucked into a container connected to the roller brush bin 2, such as a dust collection bin or a dust collection device. Exemplarily, the suction device can be a built-in or external fan on the main body of the cleaning device 1. The roller brush is arranged in the roller brush bin 2, and the roller brush at least partially extends out of the dust suction port 21, so as to contact the surface to be cleaned and clean the garbage.

[0022] In one embodiment, the cleaning device 1 includes a walking mechanism 3 disposed at the bottom thereof. Figure 1 The illustrated case is that the walking mechanism 3 is a walking wheel, and the walking mechanism 3 includes a pair of coaxially arranged walking wheels, the two walking wheels are respectively arranged at both ends of the length direction of the dust suction port 21, and the rotation axis thereof is perpendicular to the travel direction of the cleaning device 1. In other embodiments, the walking mechanism 3 may also be a walking disc extending toward the surface to be cleaned so as to contact the surface to be cleaned, and the walking disc can be moved on the surface to be cleaned by rotating the walking disc.

[0023] Exemplarily, the dust suction port 21 is located in front of the traveling direction of the cleaning device 1 relative to the walking mechanism 3 (eg Figure 1 As shown in the figure, the roller brush collects the garbage toward the dust suction port 21 during its rotation, so that the walking mechanism 3 always walks on the walking surface after the garbage has been cleared by the roller brush, thereby avoiding the garbage adhering to the walking mechanism 3 and causing secondary pollution.

[0024] like Figure 2, this embodiment provides a roller brush assembly, including: a roller brush bin 2 and two roller brushes. The roller brush bin 2 is provided with a dust suction channel 22D for communicating with a suction device, and a suction port 22 communicating with the roller brush bin 2 is arranged at the end of the dust suction channel 22D. Each roller brush includes a fixed end 222 and a free end 221. The fixed ends 222 of the two roller brushes are respectively movably assembled on both sides of the roller brush bin 2, and the free ends 221 of the roller brushes are suspended and face the suction port 22. And the central axis of the roller brush forms an angle A with the central axis C-C of the dust suction channel 22D, where the value range of A is 90° < A < 180°.

[0025] It can be understood that the free end 221 of the roller brush 22 is suspended and faces the suction port 22. It can be that the free end 221 of the roller brush 22 is arranged close to the suction port 22, it can be that the free end 221 of the roller brush 22 is closer to the suction port 22 than the fixed end 222 of the roller brush 22, it can be that the free end 221 of the roller brush 22 faces the suction port 22, or it can be that the distance between the free end 221 of the roller brush 22 and the suction port 22 is within a preset distance range.

[0026] Refer to Figure 2 , what is further shown is the situation where two roller brushes 22 are arranged in the roller brush bin 221. The two roller brushes 22A and 22B are respectively installed at opposite ends of the roller brush bin 221, and their free ends 221 are spaced apart and face each other. Specifically, the roller brush 22 includes a first roller brush 22A and a second roller brush 22B. Both the first roller brush 22A and the second roller brush 22B include a fixed end 222 and a free end 221. The fixed end 222 of the first roller brush 22A and the fixed end 222 of the second roller brush 22B are respectively rotatably arranged at opposite ends of the roller brush bin 2, and the central axis of the first roller brush 22A forms an angle A1 with the central axis C-C of the dust suction channel 22D, where 90° < A1 < 180°, and A1 is preferably 120°. And the central axis of the second roller brush 22B forms an angle A2 with the central axis C-C of the dust suction channel 22D, 90° < A2 < 180°, and A2 is preferably 120°.

[0027] Moreover, the free ends 221 of both the first roller brush 22A and the second roller brush 22B face the suction port 22, and there is a gap 22G opposite to the suction port 22 in the axial direction of the roller brush 22 between the first roller brush 22A and the second roller brush 22B. In this way, the hairs on the first roller brush 22A and the second roller brush 22B can respectively move to the gap 22G opposite to the suction port 22, and enter the suction port 22 opposite to the gap 22G under the action of vacuum suction and be collected.

[0028] Among them, it is emphasized that there is an angle A between the central axis of the rolling brush and the central axis C-C of the dust suction channel 22D, where the value range of A is 90° < A < 180°. In the embodiment, there is an angle A between the central axis of the rolling brush and the central axis C-C of the dust suction channel 22D, which is preferably 120° in this embodiment. The resulting effect is that the rolling brush is inclined towards the dust suction channel 22D (see Figure 2 ). The function of this design is as follows:

[0029] Enhance the adsorption force: Since the rolling brush is inclined towards the dust suction channel 22D (by keeping the angle between the rolling brush and the dust suction channel obtuse), when the suction device works, the negative pressure generated can act more effectively on the surface of the rolling brush, thereby enhancing the adsorption force on dust, hair and other garbage. This design enables the rolling brush to more easily push the garbage towards the suction port 22 during rotation, improving the cleaning efficiency.

[0030] Reduce hair entanglement: When the hair on the surface of the rolling brush needs to be sucked into the dust suction channel 22D, since the rolling brush is inclined towards the dust suction channel 22D (the specific angle is the same as above), the hair needs to turn an obtuse bend. This design is more conducive to the hair smoothly entering the dust suction channel 22D compared to a right-angle or acute-angle bend, reducing the entanglement of hair on the rolling brush.

[0031] Improve the cleaning effect: Since the rolling brush is inclined towards the dust suction channel 22D, the rolling brush can better fit the surface to be cleaned during rotation, thereby collecting garbage more comprehensively. At the same time, due to the enhanced adsorption force and reduced hair entanglement, the cleaning device 1 can clean the surface to be cleaned more thoroughly, improving the cleaning effect.

[0032] Prolong the life of the rolling brush: Reducing the entanglement of hair on the rolling brush can reduce the wear degree of the rolling brush, thereby prolonging the service life of the rolling brush. For users, this means less maintenance cost and longer usage time.

[0033] See Figure 3 , Embodiment 2:

[0034] Although the above Embodiment 1 also solves the problem of adsorption force, there may still be a small problem that the collected hair accumulates at this gap and cannot be sucked out. At the same time, there may be cleaning dead corners in Embodiment 1. For example, when moving forward, there will still be cleaning dead corners (gap 22G); Therefore, to solve the problem of cleaning dead corners and at the same time ensure the adsorption force,

[0035] See Figure 3 , different from Embodiment 1, in this embodiment, the first rolling brush 22A and the second rolling brush 22B are asymmetric, that is, they are placed front and back,

[0036] The specific effects of this design are as follows:

[0037] The free end 221 of the first roller brush 22A is located in front of the free end 221 of the second roller brush 22B. This configuration ensures that when the cleaning device 1 moves forward, the two roller brushes can continuously cover the area to be cleaned. Since the two roller brushes are placed front and back, there is no horizontal gap between them, thereby avoiding cleaning dead corners caused by the gap. Although there may be a vertical gap, the dust or hair in this area will be cleaned by the second roller brush 22B at the rear, ensuring the overall cleaning effect.

[0038] The first roller brush 22A pushes the hair from the free end 221 to the free end 221 of the second roller brush 22B, and then the second roller brush pushes the hair to the suction port 22. This continuous pushing method ensures effective collection of the hair.

[0039] Moreover, in the present embodiment 2, since the free end 221 of the first roller brush 22A is located at the second roller brush 22B, the design is maintained similar to that of the embodiment 1, that is, it is inclined toward the suction port 22 (its angle limit is the same as that of the specific embodiment 1), the suction force of the suction device on the garbage is enhanced, so that the garbage such as hair is more easily sucked into the suction port 22. At the same time, the hair of the first roller brush 22A is transported from the free end 221 to the free end 221 of the second roller brush 22B, and the free end 221 of the second roller brush 22B transports the excess hair to the suction port 22. The continuous pushing action of the two roller brushes enables the garbage to be collected into the suction port 22 more quickly, thereby improving the cleaning efficiency.

[0040] See also Figure 3 In this embodiment 2, it is also particularly defined that the free end 221 of the first roller brush 22A and the free end 221 of the second roller brush 22B are both located on the vertical plane of the central axis CC of the dust suction channel 22D. That is, it is ensured that the ends of the two roller brushes and the dust suction channel 22D are on the same straight line.

[0041] Since the ends of the two roller brushes are aligned with the central axis CC of the dust suction channel 22D, when the roller brushes rotate and push hair and dust, these garbage can enter the dust suction channel 22D more directly and efficiently, reducing the loss and dispersion during the dust suction process. When the ends of the roller brushes are aligned with the central axis CC of the dust suction channel 22D, it can ensure that the garbage can be sucked in more effectively in the area covered by the roller brushes, further reducing the cleaning dead corners.

[0042] See also Figure 4 , Example 3:

[0043] In Embodiment 3, the free end 221 of the first roller brush 22A and the free end 221 of the second roller brush 22B both pass through the vertical plane of the central axis CC of the dust collection channel 22D. This design brings several significant advantages and considerations:

[0044] Enhanced adsorption effect: Since the free end of the roller brush passes through the vertical plane of the central axis CC of the dust suction channel, this means that during the rotation of the roller brush, its free end can more directly approach or contact the central area of ​​the dust suction channel, so that garbage and hair can be more directly sucked into the dust suction channel, thereby enhancing the adsorption effect of the cleaning device.

[0045] Reducing cleaning dead angles: By allowing the free end of the roller brush to pass through the vertical plane of the central axis CC of the dust suction channel, it can be ensured that within the area covered by the roller brush, especially near the free end of the roller brush, garbage and hair can be sucked in more effectively, reducing cleaning dead angles.

[0046] See also Figure 1-4 Regarding the structure of the roller brush, in one embodiment, the brush body is spirally arranged around the circumference of the roller brush main body 221. During the rotation of the roller brush, the hair wrapped around the surface of the roller brush can be guided along the spiral surface of the brush body to the free end 221 of the roller brush and enter the suction port. The brush body can be a flexible brush part.

[0047] It can be understood that the above embodiment describes an example in which the brush body is spirally arranged around the circumference of the roller brush body. In other embodiments, the roller brush may also be in a truncated cone shape.

[0048] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
