Description

Technical Field

[0001] This utility model belongs to the field of cosmetic pen technology, specifically relating to a rotary cosmetic pen. Background Technology

[0002] Cosmetics are common items in modern life. They can beautify and enhance one's appearance, boosting confidence and making them popular among beauty enthusiasts. In a makeup brush, the liquid inside flows into the brush and colors it. When using a makeup brush, the brush is applied to specific areas of the body to color the skin and hair, or to style hair, achieving skincare and makeup effects.

[0003] Existing cosmetic pens have a tubular liquid storage space inside for storing cosmetic liquid. The cosmetic liquid in the tubular liquid storage space is pumped out by a vacuum pump body. This pumping method is generally carried out by pressing. This method is relatively inefficient because the pump body pumps once with each press. Therefore, this utility model designs a rotary cosmetic pen. Utility Model Content

[0004] The purpose of this invention is to provide a rotary makeup brush to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary cosmetic pen, comprising a liquid storage bottle, a pump body base installed at the bottle opening, a pumping pipe provided on the inner side of the pump body base, a pump body that can be raised and lowered connected to the top end of the pumping pipe, and a spring sleeve for resetting the pump body fitted on the outer side of the pumping pipe, the pump body base and the pump body being fitted with the same rotating sleeve, the rotating sleeve being rotatably mounted on the liquid storage bottle, a liquid delivery pipe provided at the top end of the rotating sleeve, the bottom end of the liquid delivery pipe extending and communicating with the pump body, a brush mounted on the top of the rotating sleeve, and the top end of the liquid delivery pipe connected to the brush, a detachable pen cap fitted on the outer side of the brush, and a rotary pressing assembly for driving the pump body to press down between the rotating sleeve and the pump body.

[0006] Preferably, the rotating pressing assembly includes multiple arc-shaped grooves formed around the outer side of the pump body, and multiple extrusion protrusions disposed on the inner side of the rotating sleeve. The multiple extrusion protrusions extend into any of the arc-shaped grooves, and the extrusion protrusions can be made to press the pump body downward by rotating the rotating sleeve.

[0007] Preferably, the arc-shaped groove is an arc-shaped spiral groove, and the maximum depth of the arc-shaped groove matches the longitudinal height of the extruded protrusion.

[0008] Preferably, the rotating sleeve, the liquid delivery tube, and the extrusion protrusion are integrally formed into a single structure, and the brush is provided with an outlet hole that communicates only with the top of the liquid delivery tube.

[0009] Preferably, the pump body base is screwed into the liquid storage bottle via threads, and the top end of the rotating sleeve is engaged with the pen cap via a protrusion.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features a pump body with multiple arc-shaped grooves and a rotating sleeve with extrusion protrusions. By rotating the rotating sleeve, the extrusion protrusions on the inner side of the rotating sleeve move along the arc-shaped grooves, forcing the extrusion protrusions to press against the arc-shaped grooves, thus pressing down the pump body and completing the function of pumping cosmetic liquid from the storage bottle. The pump body can be pressed multiple times within the rotation range of the rotating sleeve, achieving a rapid liquid dispensing effect compared to the direct pressing method of transmission.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1-5This utility model provides a technical solution: a rotary cosmetic pen, including a liquid storage bottle 1, a pump body seat 6 installed at the mouth of the liquid storage bottle 1, a pumping pipe 11 provided on the inner side of the pump body seat 6, a pump body 7 that can be raised and lowered connected to the top end of the pumping pipe 11, and a spring sleeve 10 for resetting the pump body 7 is sleeved on the outer side of the pumping pipe 11. The pump body seat 6 and the pump body 7 are sleeved with the same rotating sleeve 2 that can be limited to rotate. The rotating sleeve 2 is rotatably mounted on the liquid storage bottle 1. A liquid delivery pipe 5 is provided at the top end of the rotating sleeve 2. The bottom end of the liquid delivery pipe 5 extends and communicates with the pump body 7. A brush 4 is installed at the top of the rotating sleeve 2, and the top end of the liquid delivery pipe 5 is connected to the brush 4. A detachable pen cap 3 is sleeved on the outer side of the brush 4. A rotary pressing component for driving the pump body 7 to press down is provided between the rotating sleeve 2 and the pump body 7. In this embodiment, preferably, the rotating pressing component includes multiple arc-shaped grooves 8 formed around the outer side of the pump body 7, and multiple extrusion protrusions 9 disposed inside the rotating sleeve 2. The multiple extrusion protrusions 9 extend into any of the arc-shaped grooves 8, and by rotating the rotating sleeve 2, the extrusion protrusions 9 can press the pump body 7 downward.
