As shown in <FIG>, in another embodiment of the present disclosure, specifically referring to <FIG>, a cosmetic tool is provided, which includes:.

The brush head <NUM> is provided with a connecting shaft <NUM>, and a rotating structure includes a semicircular hole <NUM> and a limiting groove <NUM>; the semicircular hole <NUM> is disposed on the inner wall of the moving sleeve <NUM> and centered on the rotation axis around which the brush head <NUM> rotates, a connecting line between both ends of the semicircular hole <NUM> is parallel to the axial direction of the moving sleeve <NUM>, the limiting groove <NUM> is disposed on the inner wall of the fixed sleeve <NUM>, the limiting groove <NUM> is perpendicular to the axial direction of the moving sleeve <NUM>, and the end portion of the connecting shaft <NUM> penetrates the semicircular hole <NUM> and the limiting groove <NUM>. The limiting groove <NUM> can be a straight groove or an arc groove extending along the circumferential direction of the fixed sleeve <NUM>.

The cosmetic tool according to the embodiments of the present disclosure will be further described below. For the cosmetic tool, the end portion of the connecting shaft <NUM> on the brush head <NUM> penetrates the semicircular hole <NUM> and the limiting groove <NUM>, the limiting groove <NUM> is perpendicular to the axial direction of the moving sleeve <NUM>, the semicircular hole <NUM> is centered on the rotation axis around which the brush head <NUM> rotates, and the connecting line between both ends of the semicircular hole <NUM> is parallel to the axial direction of the moving sleeve <NUM>, so that when it needs for the brush head <NUM> to dip in the cosmetic substance at the discharge port of the material core <NUM>, the moving sleeve <NUM> is pushed to move along the axial direction and towards the brush head <NUM>, thereby realizing the turning over and dipping of the brush head <NUM>. In this process, the connecting shaft <NUM> on the brush head <NUM> is limited by the limiting groove <NUM>, so that the brush head <NUM> will not move along with the moving sleeve <NUM> along the axial direction. At the same time, as driven by the semicircular hole <NUM>, the connecting shaft <NUM> on the brush head <NUM> moves from one end to the other end along the semicircular hole <NUM>, so as to drive the brush head <NUM> to turn over relative to the moving sleeve <NUM>, and the overturned brush head <NUM> dips in the cosmetic substance at the discharge port of the material core <NUM>, thereby realizing the dipping in the cosmetic substance with the brush head <NUM>. For the cosmetic tool according to the embodiments of the present disclosure, the turnover of the brush head <NUM> can be realized through the connection and cooperation among the connecting shaft <NUM> on the brush head <NUM>, the semicircular hole <NUM> on the moving sleeve <NUM> and the limiting groove <NUM> on the fixed sleeve <NUM>, and thus the cosmetic tool has the advantages of a simple structure, convenient manufacture, few parts, simple transmission, good use reliability and long service life.

For the cosmetic tool of the embodiments of the present disclosure, when in use, the dipping of the cosmetic substance can be realized by driving the moving sleeve <NUM> to move, so that the operation of the cosmetic tool is simple. Additionally, the material core <NUM> and the brush head <NUM> are integrated in one component of the cosmetic tool, and thus is convenient to carry when going out.

In another embodiment of the present disclosure, as shown in <FIG>, <FIG> and <FIG>, the inner wall of the moving sleeve <NUM> of the provided cosmetic tool is provided with a rotation post <NUM>, the peripheral wall of the brush head <NUM> is provided with a rotation groove <NUM>, and the rotation post <NUM> is rotatably connected in the rotation groove <NUM>. Specifically, the rotation post <NUM> is inserted in the rotation groove <NUM> and can rotate in the rotation groove <NUM>, and the rotation post <NUM> is disposed in parallel with the connecting shaft <NUM> at intervals. Through the rotating cooperation between the rotation post <NUM> and the rotation groove <NUM>, the rotatable connection between the brush head <NUM> and the moving sleeve <NUM> is realized, which has a simple structure and is convenient to manufacture.

In another embodiment of the present disclosure, the inner wall of the moving sleeve <NUM> of the provided cosmetic tool is provided with a rotation groove <NUM>, and the peripheral wall of the brush head <NUM> is provided with a rotation post <NUM> which is rotatably connected in the rotation groove <NUM>. Specifically, the rotation post <NUM> is inserted in the rotation groove <NUM> and can rotate in the rotation groove <NUM>, and the rotation post <NUM> is disposed in parallel with the connecting shaft <NUM> and at intervals along the axial direction of the moving sleeve <NUM>. Through the rotating cooperation between the rotation post <NUM> and the rotation groove <NUM>, the rotatable connection between the brush head <NUM> and the moving sleeve <NUM> is realized, which has a simple structure and is convenient to manufacture.

In another embodiment of the present disclosure, as shown in <FIG>, <FIG> and <FIG>, the rotation groove <NUM> of the provided cosmetic tool is an elongated groove. The rotation groove <NUM> is parallel to the axial direction of the moving sleeve <NUM>; the inner wall of the moving sleeve <NUM> is also provided with a linear hole <NUM>, which is communicated with the end portion of the semicircular hole <NUM> and extends along the axial direction of the moving sleeve <NUM> and away from the semicircular hole <NUM>. Specifically, the linear hole <NUM> can be located between the semicircular hole <NUM> and the material core <NUM>, or at the side of the semicircular hole <NUM> facing away from the material core <NUM>. When the linear hole <NUM> is located between the semicircular hole <NUM> and the material core <NUM>, and the moving sleeve <NUM> moves until the brush head <NUM> is turned over by <NUM>° and dips in the cosmetic material, because the rotation post <NUM> can continue to move along the rotation groove <NUM> while the connecting shaft <NUM> can also continue to move along the linear hole <NUM>, the moving sleeve <NUM> can continue to move along the axial direction, and thus the brush head <NUM> is driven to continually move towards the discharge port of the material core <NUM>. Therefore, the amount of the cosmetic substance dipped with the brush head <NUM> can be adjusted by controlling the moving distance of the moving sleeve <NUM>. When the moving sleeve <NUM> continues to move for a large distance, the pressing force by which the brush head <NUM> is tightly pressed at the discharge port is large, and more cosmetic substance is dipped by the brush head <NUM>; and when the moving sleeve <NUM> continues to move for a short distance, the pressing force by which the brush head <NUM> is tightly pressed at the discharge port is small, and less cosmetic substance is dipped by the brush head <NUM>. When the linear hole <NUM> is located at the side of the semicircular hole <NUM> facing away from the material core <NUM>, and after the brush head <NUM> turns over reversely by <NUM>° as driven by the moving sleeve <NUM> so that the brush head <NUM> is exposed outside the moving sleeve <NUM>, since the rotation post <NUM> can continue to move along the rotation groove <NUM> while the connecting shaft <NUM> can also continue to move along the linear hole <NUM>, the moving sleeve <NUM> can continue to move along the axial direction, so as to drive the brush head <NUM> to continually move towards the outside of the moving sleeve <NUM>, so that the exposed part of the dipping member <NUM> of the brush head <NUM> can be gradually increased, thereby facilitating the brushing of the cosmetic substance. Meanwhile, during the brushing process of the cosmetic substance, components such as the moving sleeve <NUM> and the fixed sleeve <NUM> will not rub against the skin, thereby improving the brushing comfort of the cosmetic substance. After the rotation post <NUM> enters the rotation groove <NUM> and the connecting shaft <NUM> also enters the linear hole <NUM>, the brush head <NUM> will not turn over when the cosmetic substance is brushed, which makes the operation of brushing the cosmetic substance simpler and easier.

In another embodiment of the present disclosure, as shown in <FIG>, <FIG> and <FIG>, both ends of the semicircular hole <NUM> of the provided cosmetic tool are communicated with the linear hole <NUM>. Specifically, the number of the linear holes <NUM> is two, wherein one linear hole <NUM> can be located between the semicircular hole <NUM> and the material core <NUM>, and the other linear hole <NUM> is located at the side of the semicircular hole <NUM> facing away from the material core <NUM>. From the above analysis, it can be seen that in the cosmetic tool, the amount of cosmetic substance dipped by the brush head <NUM> can be adjusted, and at the same time, the brush head <NUM> will not turn over during the process of brushing the cosmetic substance onto the skin by the brush head <NUM>, so that the operation of brushing the cosmetic substance by the brush head <NUM> is simpler and easier.

Specifically, the moving sleeve body <NUM> serves as a mounting base of the material core <NUM>, and the moving arm <NUM> serves as a mounting base of the brush head <NUM>. At the same time, a gap formed between the two moving arms <NUM> can provide a turnover space for the brush head <NUM> to turn over, so that the turnover of the brush head <NUM> is smoother and more reliable. Additionally, the two ends of the connecting shaft <NUM> are respectively connected by penetrating the semicircular holes <NUM> of the two moving arms <NUM>, so that the reliability of the connection between the brush head <NUM> and the moving sleeve <NUM> is good, and the reliability and stability of the turnover of the brush head <NUM> are better. In order to improve the reliability and stability of the turnover of the brush head <NUM>, the two moving arms <NUM> are both provided with rotation posts <NUM>, the two opposite sides of the brush head <NUM> are both provided with rotation grooves <NUM>, and the two rotation posts <NUM> are rotatably connected in the rotation grooves <NUM> respectively.

Specifically, the fixed sleeve body <NUM> is sleeved outside the moving sleeve body <NUM>, and the gap formed between the two fixed arms <NUM> can provide a turnover space for the brush head <NUM> to turn over, so that the turnover of the brush head <NUM> is smoother and more reliable. Additionally, the two ends of the connecting shaft <NUM> are respectively inserted into the two limiting grooves <NUM>, so that the reliability of the connection between the brush head <NUM> and the fixed sleeve <NUM> is good, and the reliability and stability of the turnover of the brush head <NUM> are better.

Specifically, when the moving sleeve <NUM> is pushed to move towards the brush head <NUM>, the elastic member <NUM> is compressed. When the moving sleeve <NUM> is moved into position, that is, after the brush head <NUM> dips in the cosmetic substance, the elastic member <NUM> drives the moving sleeve <NUM> to move reversely under the action of its own restoring force, realizing the automatic reset of the moving sleeve <NUM>, and drives the brush head <NUM> to move reversely and turn over reversely, realizing the automatic reset of the brush head <NUM>. Thus, the use of the cosmetic tool is simple and convenient. The elastic member <NUM> is an elastic component, such as a spring.
