[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-8 , the present utility model provides a technical solution: a replaceable middle core, including a housing 1, a cup holder 2 for containing lipstick paste is vertically slidably connected inside the housing 1, a base 3 is detachably installed at the bottom of the housing 1, and a driving member is arranged between the base 3 and the lipstick cup holder 2, and the driving member is used to drive the cup holder 2 to slide vertically.

[0031] Specifically, the replaceable middle core includes a housing 1. Specifically, the housing 1 is made of aluminum alloy, which can further improve the quality of the entire lipstick tube and further extend the service life of the middle core to meet the working requirements. Inside the housing 1, there is a vertically slidable cup 2 for holding the lipstick paste. When the lipstick is to be used, the cup 2 drives the lipstick paste to slide upward so that the lipstick paste can be used after sliding to a predetermined position. At the bottom of the housing 1, a base 3 is detachably installed. A driving member is provided between the base 3 and the lipstick cup 2, and the driving member is used to drive the cup 2 to slide vertically. At this time, when the lipstick is to be used, by driving the base 3 to rotate, during the rotation stroke of the base 3, the cup 2 is driven to slide upward through the driving member so that the lipstick paste can be used after sliding to a predetermined position. Therefore, during use, after a lipstick paste is used up, the base 3 is detached from the housing 1, which facilitates the detachment of components such as the cup 2 carried by the base 3 from the housing 1 together. After cleaning, it can be reinstalled on the base 3 for use, thus achieving the effect of recycling the middle core. At the same time, if a middle core is damaged, it can be directly detached from the base 3 and a new middle core can be replaced, with better use effect.

[0032] In the embodiment provided by the present utility model, the driving member includes a driving rod 4 vertically slidably connected inside the housing 1. The cup 2 is connected to the driving rod 4. An external thread 6 is provided on the outer side of the driving rod 4, and an internal thread 5 is provided on the base 3. The external thread 6 is threadedly connected to the internal thread 5. Therefore, during use, during the rotation stroke of the base 3, the driving rod 4 is driven to slide vertically through the cooperation between the internal thread 5 and the external thread 6, and the cup 2 is driven to slide upward through the driving rod 4 to meet the working requirements.

[0033] In the embodiment provided by the present utility model, the base 3 is rotatably connected to the housing 1 through a limiting portion 12, which can further improve the stability of the base 3 during rotation.

[0034] In the embodiment provided by the present utility model, the limiting portion 12 includes a convex ring provided on the base 3, and an annular groove is provided on the housing 1. The convex ring is rotatably connected in the annular groove. Specifically, the convex ring is made of an elastic material, which facilitates the installation and disassembly of the base 3 to meet the working requirements.

[0035] In another embodiment provided by the present utility model, the driving member includes a power rod 8 vertically slidably connected inside the housing 1. The cup 2 is fixedly connected to the power rod 8; a sphere 10 is fixedly connected to the base 3, and a thread 9 is provided on the power rod 8. The sphere 10 is adapted to the thread 9. Therefore, during use, when the base 3 rotates, the vertical sliding of the power rod 8 can be driven by the movement of the sphere 10 inside the thread 9 to meet the working requirements.

[0036] In the embodiments provided by the present utility model, a rotation prevention component is further provided between the base 3 and the housing 1, so as to improve the stability during the installation of the base 3 and reduce the situation that the base 3 rotates due to accidental touch, with better effects.

[0037] In the embodiments provided by the present utility model, the rotation prevention component includes multiple groups of rotation prevention pieces 7. The multiple groups of rotation prevention pieces 7 are arranged in a circumferential array on the base 3, and the rotation prevention pieces 7 are in contact with the housing 1 to achieve the effect of preventing rotation.

[0038] In the embodiments provided by the present utility model, the rotation prevention piece 7 is made of an elastic material.

[0039] In the embodiments provided by the present utility model, the lipstick cup 2 is provided with fastening pieces 11 for fastening the lipstick body. The multiple groups of fastening pieces 11 are circumferentially and arrayedly distributed inside the lipstick cup 2, so as to improve the stability during the installation of the lipstick body.
