Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a pollution-preventing lint stick. BACKGROUND

[0002] Lint stick, as a widely used cleaning tool, plays an important role in various occasions such as family, office and clothing factory due to its convenience and efficiency. Its typical structure is composed of a handle and a lint roller arranged on the handle. Users drive the lint roller to roll on the surface of the adherend by pushing and pulling the handle, easily removing the hair, dust and small sundries on the surface of clothes, furniture and carpet. However, although the lint stick has made significant progress in design and function, there are still some improvements to be made.

[0003] On the one hand, taking the Chinese utility model patent with the patent number CN214458906U as an example, the patent discloses a lint stick with a roller, which is characterized in that the lint roller is rotatably installed in the outer shell, and the outer shell provides two handle connection modes, which not only increases the flexibility of use, but also improves the stability and lint effect of the device. However, the lint stick still has some deficiencies in external design, i.e. the coverage of the outer cover is not complete. Specifically, although the outer shell provides some protection for the lint roller, it does not completely cover the lint roller, which makes the lint roller vulnerable to dust or small pollutants when placed outdoors, thereby affecting its cleaning effect and service life.

[0004] On the other hand, taking the Chinese utility model patent with the patent number CN215937291 as an example, the patent discloses a lint stick with an outer cover, which can be sleeved on the roller and connected with the handle through the clamping groove and clamping part, effectively preventing the outer cover from falling off. However, this design also has certain limitations. During use, the user needs to detach the outer cover from the lint stick before operation, which not only increases the complexity of operation, but also may cause the loss of the outer cover. Once the outer cover is lost, the lint roller will lose protection and face the risk of being contaminated again. UTILITY MODEL CONTENTS

The protective cover includes an upper cover body and a lower cover body. In a natural state, the upper cover body and the lower cover body completely cover the periphery of the lint roller, forming an effective isolation barrier to prevent dust, hair and other impurities from contacting and adhering to the lint roller, thereby maintaining the cleanliness and stickiness of the lint roller and prolonging the service life of the lint roller.

Further, the outer surface of one side of the upper cover body abuts against the bracket, so that one side of the upper cover body protrudes from the bracket or is flush with the outer wall of the bracket. The horizontal plane where the edge of the other side of the upper cover body is located is lower than the horizontal plane where the bracket protruding shaft is located, that is, the upper cover body and the handle are in an inclined state. When the lint remover is used to stick lint on the bed surface or the floor, the handle and the bed surface or the floor form an angle of less than 90 degrees. Since one side of the upper cover body protrudes from the bracket or is flush with the outer wall of the bracket, the lint opening is directly opposite the bed surface or the floor surface, so that the protective cover will not be caught on the bed surface or the floor surface and will not be scratched. In addition, when the lint remover is hung for storage, since the upper cover body and the handle are in an inclined state, the outer surface of the other end of the upper cover body, which is flush with the horizontal plane where the bracket protruding shaft is located, contacts the wall, further protecting the lint roller from being rotated by mistake, exposing the lint roller and causing the lint roller to directly contact the wall, resulting in contamination of the lint roller.

[0031] By providing bracket protruding shafts at both ends of the bracket and corresponding lint roller insertion slots at both ends of the lint roller, the bracket protruding shafts are inserted into the lint roller insertion slots to achieve rotatable connection of the lint roller and the bracket, preventing the lint roller from shaking or falling off during use and improving the stability and durability of the lint remover. By providing a strip-shaped protrusion and a strip-shaped recess, as well as a protruding portion and a third recess, the connectivity between the protective cover and the bracket is increased.
