Description

Technical Field

[0001] This utility model relates to related technical fields, and in particular to a lint remover. Background Technology

[0002] In the textile industry, garments made of various fibers inevitably experience pilling and fuzzing due to friction during use and washing. This phenomenon severely affects the aesthetics and comfort of clothing. To address this issue, lint removers have become common care tools. Existing lint removers typically use a built-in rotating blade to cut off lint from the surface of clothing and are equipped with a corresponding collection mechanism to handle the cut lint. One mainstream solution involves incorporating a blower mechanism and a lint collection chamber. Specifically, a fan generates airflow inside the remover, blowing or sucking the cut lint into a dedicated collection chamber to collect the lint and prevent it from scattering and tangling. However, this solution has significant limitations. The addition of a blower mechanism (such as a fan or air duct) and a lint collection chamber with a certain capacity inevitably increases the overall size and complexity of the product. This makes traditional lint removers less portable and less suitable for users traveling or carrying around for immediate care. Utility Model Content

[0021] Reference Figures 1 to 4According to a first aspect of the present invention, a lint remover includes a base 100, a drive device 200, a blade assembly 300, and a cover 400. The base 100 is cylindrical and includes a bottom shell 110 and a cover 120. The cover 120 is mounted on the top of the bottom shell 110, and the cover 120 and the bottom shell 110 enclose a first receiving cavity 130. The bottom of the bottom shell 110 is also provided with a first receiving groove 140 with its opening facing downward. A mesh cover 150 is provided at the opening of the first receiving groove 140. The drive device 200 is disposed in the first receiving cavity 130 and includes a drive motor 210, an energy storage component 220, and a control component 230 connected to each other. The drive motor 210 is vertically disposed in the first receiving cavity 130. The cavity 130 and the cover 120 are provided with an arched part 121 for accommodating the drive motor 210. The tool assembly 300 is connected to the drive motor 210 and is located in the first receiving groove 140. The drive motor 210 can drive the tool assembly 300 to rotate. The cover 400 is detachably installed on the top of the base 100 and surrounds the cover 120 to form a second receiving cavity 410. The cover 400 is provided with an air outlet 420. The cover 120 is provided with a vent 122 surrounding the arched part 121. The bottom shell 110 is provided with a duct 111 that connects the first receiving groove 140 with the vent 122. When the tool assembly 300 rotates, it can drive the airflow through the vent 122 to the second receiving cavity 410. By setting the cover plate with an arched portion 121, the drive motor 210 can be avoided, while the volume of the second receiving cavity 410 can be maintained as much as possible, making the overall structure more compact. At the same time, the blade assembly 300 can generate airflow when rotating, blowing the lint balls into the second cavity through the air duct 111, preventing lint balls from accumulating in the first receiving groove 140, thus reducing the possibility of the blade assembly 300 being entangled and damaged. Furthermore, there is no need for a fan component, making the overall structure simpler and more compact. Moreover, by placing the air holes 122 around the arched portion 121, the arched portion 121 acts as a guide, directing the airflow into the air holes 122 to flow around the arched portion 121, reducing air resistance and facilitating the collection of lint balls.

[0022] Specifically, the bottom of the bottom shell 110 can be provided with a first receiving groove 140, and the top can also be provided with a groove. The drive motor 210, energy storage component 220 and control component 230 can be installed on the groove. Then, the cover 120 is connected to the bottom shell 110 to form a first receiving cavity 130. The energy storage component 220 can be a battery, and the control component 230 is a conventional circuit board structure. The middle part of the cover 120 can be provided with a gradually arched part 121. The arched part 121 and the drive motor 210 are both located in the middle. Therefore, the arched part 121 can avoid the drive motor 210. The drive motor 210 can be circumferentially arranged with components such as the energy storage component 220, control component 230 and air duct 111, which can make full use of space and reduce the overall size of the lint remover, making it easy to carry. In actual use, the mesh cover 150 has dense holes, allowing lint to enter the first receiving groove 140 through these holes. The cutter assembly 300 can cut the lint, and as the cutter assembly 300 rotates, it drives airflow through the duct 111 and the air vent 122 towards the second receiving cavity 410. The cut lint is kept in the second receiving cavity 410 by the airflow, preventing lint from accumulating in the first receiving groove 140 where the cutter assembly 300 is located, thus avoiding any impact on its operation. The air vent 122 is located around the arched portion 121, which acts as an airflow guide, directing the airflow around the arched portion 121 to reduce turbulence and thus resistance. After use, the cover 400 can be removed to clean out the lint. It is conceivable that a filter screen could be installed on the air vent 122.

[0023] Reference Figure 3 In some embodiments of this utility model, the bottom of the arched portion 121 is provided with a positioning portion 1211, which abuts against the top of the drive motor 210 and positions the drive motor 210. Specifically, the positioning portion 1211 can be a raised annular boss that abuts against the drive motor 210 to limit the shaking or movement of the drive motor 210 and thus play a positioning role.

[0024] Reference Figures 2 to 4 In some embodiments of this invention, the energy storage component 220 is cylindrical and extends horizontally, positioned on one side of the drive motor 210. Specifically, the energy storage component 220 can be arranged laterally and located on one side of the drive motor 210 to save longitudinal space, allowing it to be accommodated at the bottom of the cover 120 circumferentially around the arched portion 121. This maximizes space utilization.

[0025] Reference Figures 2 to 4In some embodiments of this utility model, the control component 230 includes a control circuit board 231. The control circuit board 231 is rectangular in shape, with its length direction in the horizontal direction and its width direction in the vertical direction. The control circuit board 231 is located on the side of the energy storage component 220 away from the drive motor 210. The control circuit board 231 can also utilize the lateral space to be accommodated at the bottom of the arched portion 121.

[0026] Reference Figures 2 to 4 In some embodiments of this utility model, the control component 230 further includes a control button 232 and a charging interface 233. The side wall of the bottom shell 110 is provided with a clearance hole for the control button 232 and the charging interface 233 to extend out. The control circuit board 231 is close to the side wall of the bottom shell 110, which allows the control button 232 and the charging interface 233 to extend directly out of the bottom shell 110. Users can perform control operations and charging operations on the side wall of the bottom shell 110.

[0027] Reference Figures 2 to 4 In some embodiments of this invention, the duct 111 is located on the side of the drive motor 210 away from the energy storage component 220. Specifically, the duct 111 can be arranged in the empty space on the other side of the drive motor 210, and the area of ​​the empty space is relatively large to facilitate the installation of a duct 111 with a large cross-sectional area, so that lint can be collected in the second receiving cavity 410. The above structure can also make full use of space, which facilitates further reduction of the volume of the lint remover.

[0028] Reference Figures 2 to 4 In some embodiments of this utility model, the bottom shell 110 is provided with a detachable bottom cover 112, and the bottom cover 112 is provided with a mesh cover 150. The bottom cover 112 can be removed to clean the blade 320 assembly and to clean the first receiving groove 140.

[0029] Reference Figures 2 to 3In some embodiments of this utility model, the bottom cover 112 is provided with a snap-fit ​​structure between itself and the bottom shell 110.

The snap-fit ​​groove 1121 includes a vertical portion 1121a and an annular portion 1121b. After the snap-fit ​​block 113 is snapped into the vertical portion 1121a, rotating the bottom cover 112 and the bottom shell 110 relative to each other can drive the snap-fit ​​block 113 into the annular portion 1121b. Specifically, the snap-fit ​​groove 1121 can be provided on the bottom cover 112, the snap-fit ​​block 113 can be provided on the bottom shell 110, and two snap-fit ​​grooves 1121 can be provided, which can be arranged opposite to each other. During installation, the locking block 113 can be aligned with the vertical part 1121a, and then the locking block 113 can be inserted into the vertical part 1121a in the axial direction. Then, the bottom cover 112 is twisted so that the locking block 113 can be engaged in the annular groove to achieve a locking connection. Disassembly is performed by reversing the operation. This facilitates the disassembly and assembly of the bottom cover 112 and makes cleaning easier.
