Description

Technical Field

[0001] This utility model relates to the field of powder brush technology, and in particular to a powder brush that can control the opening or closing of the cavity containing cosmetic powder. Background Technology

[0002] CN206342118 utility model patent discloses a telescopic powder brush for cosmetics, including a handle, a brush head, a telescopic sleeve, and a brush cap. The brush head is disposed at the upper end of the handle, and the telescopic sleeve is movably sleeved on the outside of the handle. The outer surface of the upper end of the telescopic sleeve has a first retaining edge, and the inner surface of the lower end of the brush cap has at least two engaging protrusions corresponding to the first retaining edge. The outer surface of the upper end of the handle has a first limiting edge, and the inner surface of the lower end of the telescopic sleeve has a second limiting edge corresponding to the first limiting edge. When the telescopic sleeve is at its starting position, the brush head is positioned above the telescopic sleeve; when the telescopic sleeve moves upward along the handle to its ending position, the telescopic sleeve is sleeved on the outside of the brush head. From the above technical solution, it can be seen that loose powder is difficult to control and easily wasted. Summary of the Invention

[0003] The purpose of this invention is to provide a powder brush. This invention uses a telescopic tube to move up and down to drive a rotating tube to control the connection or closure between the receiving cavity and the brush head, effectively preventing powder waste.

[0004] To solve this technical problem, the technical solution of this utility model is: a powder brush, including a base and a receiving tube that are threadedly connected at opposite ends; the base and the receiving tube surround to form a receiving cavity; and a brush head communicating with the receiving cavity is also provided;

[0005] The outer side of the receiving tube is successively fitted with a rotating tube, a telescopic tube, and a positioning sleeve that is clamped and fixed by the base and the receiving tube;

[0006] The rotating tube and the telescopic tube are limited by the positioning sleeve;

[0007] The top end of the receiving tube is provided with a first powder outlet hole, and the top end of the rotating tube is provided with a second powder outlet hole. The rotating tube is driven to reciprocate by a telescopic tube extending or retracting between the rotating tube and the positioning sleeve. The first powder outlet hole and the second powder outlet hole are misaligned and closed or aligned and connected to realize the closure or connection between the brush head and the receiving cavity.

[0008] In a further improvement, the telescopic tube drives the rotating tube to rotate via a drive mechanism;

[0009] The driving mechanism includes a driving protrusion located on one side of the telescopic tube and a spiral concave track located on the outer wall of the rotating tube. This invention, through the cooperation of the concave track and the driving protrusion, ensures both the vertical movement of the telescopic tube and a tight fit between the telescopic tube and the rotating tube, resulting in a compact structure.

[0010] In a further improvement, positioning protrusions are provided near the upper and lower ends of the concave track. This invention incorporates two positioning protrusions within the concave track to prevent the telescopic tube from automatically retracting to its lowest position under external vibration and its own weight. This effectively ensures the stable holding of the telescopic tube at its extended and retracted target positions, while also preventing accidental opening of the receiving cavity.

[0011] In a further improvement, when the drive protrusion of the telescopic tube passes the positioning protrusion located above the concave track, the telescopic tube surrounds the brush head. When the receiving cavity is sealed, the brush head is surrounded by the telescopic tube. Due to the large and fluffy bristles of the powder brush head, the telescopic tube effectively tightens the brush head, reducing the amount of loose powder remaining in the brush head and protecting the brush head.

[0012] In a further improvement, a mounting base is threadedly connected to the top of the rotating tube, and the brush head is fixed to the mounting base; a powder outlet pipe is provided in the middle of the mounting base, and the powder outlet pipe extends into the middle of the brush head. This utility model ensures the uniform distribution of loose powder on the brush head by cooperating with the powder outlet pipe and the fluffy brush head.

[0013] In a further improvement, the positioning sleeve is fixed to the threaded connection between the receiving tube and the base via a first protruding edge. This invention features a stable structure, and when the powder in the receiving cavity is depleted and needs replenishment, the base can be rotated away from the receiving tube to replenish the powder.

[0014] In a further improvement, the positioning sleeve has multiple parallel positioning tracks arranged axially along its inner wall, and a limiting flange is provided on the inner wall of the positioning sleeve above the positioning tracks. This invention effectively positions the telescopic tube's movement path using the positioning sleeve, and its structure is compact and stable.

[0015] In a further improvement, the lower ends of the telescopic tube and the rotating tube are respectively provided with a second convex edge and a third convex edge for limiting the positioning sleeve.

[0016] In a further improvement, the positioning sleeve is fitted with a cover body.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention utilizes a base and a receiving tube to form a receiving cavity, which is connected to a brush head. A rotating tube, a telescopic tube, and a positioning sleeve, held and fixed by the base and the receiving tube, are sequentially fitted outside the receiving tube. The rotating tube and the telescopic tube are limited by the positioning sleeve. The top of the receiving tube has a first powder outlet hole, and the top of the rotating tube has a second powder outlet hole. The rotating tube is driven to reciprocate by the telescopic tube extending or retracting between the rotating tube and the positioning sleeve. The first and second powder outlet holes are either misaligned and closed or aligned and connected. When loose powder is needed, the telescopic tube is pushed between the positioning sleeve and the rotating tube, causing the brush head to loosen and be unrestrained by the telescopic tube. At this time, the first and second powder outlet holes are aligned and connected, and the brush head connects to the receiving cavity. Pulling up the telescopic tube drives the rotating tube to rotate, causing the first and second powder outlet holes to misalign and seal the receiving cavity. Simultaneously, the extended telescopic tube surrounds the brush head from below, preventing the brush head from loosening and powder from falling, thus reducing pollution or loss caused by powder.
