[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0041] Example 1

[0042] See also Figure 1-6 The technical solution of an environmentally friendly lipstick core provided in this embodiment includes the following:

[0043] The driving assembly 1 comprises a fork 11 and a base 12, wherein the base 12 is connected to the fork 11, and the base 12 is rotated to drive the fork 11 to rotate;

[0044] A barrel 2 for containing lipstick, the barrel 2 is built inside the fork 11;

[0045] A spiral 3, wherein the spiral 3 is sleeved on the outer periphery of the fork 11, and a rotation guide portion is provided on the inner wall of the spiral 3; the rotation guide portion cooperates with the rotating fork 11 to drive the barrel 2 to reciprocate along the axial direction of the fork 11;

[0046] The middle bundle tube 4 is disposed on the outer periphery of the spiral 3 and is detachably connected to the spiral 3;

[0047] The connecting member 5 comprises a connecting protrusion 51 and a connecting recess 52 which cooperate with each other. The connecting protrusion 51 is arranged on the inner wall of the middle bundle tube 4 , and the connecting recess 52 is arranged on the outer periphery of the spiral 3 .

[0048] In a specific implementation, two first annular ribs may be provided on the top of the inner wall of the base 12, and a second annular rib may be provided on the fork 11 at a position corresponding to the gap between the two first annular ribs. When the base 12 and the fork 11 are installed, the second annular rib may be rotatably accommodated between the two first annular ribs to ensure that the base 12 and the fork 11 do not fall off.

[0049] In a specific implementation, a first limiting boss and a second limiting boss that cooperate with each other can be respectively arranged on the bottom of the fork 11 and the inner wall of the base 12, and ensure that a second limiting boss is accommodated in every two adjacent first limiting bosses. When the base 12 is rotated, the second limiting boss transmits force to the first limiting boss to drive the fork 11 to rotate.

[0050] Specifically, the fork 11, the base 12, the barrel 2 and the spiral 3 are all made of the same material.

[0051] Specifically, the fork 11, the base 12, the barrel 2 and the spiral 3 are made of environmentally friendly materials including PP and PET; the middle beam tube 4 is made of metal materials including aluminum.

[0052] Specifically, the connection protrusion 51 and the middle bundle tube 4 are an integrated structure, and the connection recess 52 and the spiral 3 are an integrated structure;

[0053] The number of the connecting protrusions 51 is the same as the number of the connecting recesses 52 , and a plurality of the connecting protrusions 51 are evenly arranged on the inner wall of the middle bundle tube 4 ; a plurality of the connecting recesses 52 are arranged on the spiral 3 at positions corresponding to the connecting protrusions 51 .

[0054] In a specific implementation, the connecting protrusion 51 and the connecting recess 52 are designed according to the actual diameter of the middle bundle core. The length / depth of the connecting protrusion 51 and the connecting recess 52 should not be too shallow, otherwise it is easy to fall off during use. The separation force of the middle bundle tube 4 and the spiral 3 is greater than 3KG, and the rotational torque of the middle bundle tube 4 and the spiral 3 is 50-300g*cm. Under this condition, when the middle bundle core is recycled, the aluminum middle bundle can be separated by a machine to achieve classified recycling.

[0055] Preferably, when the number of the connecting protrusions 51 and the connecting recesses 52 is 15, the corresponding disengagement force needs to be greater than 3KG. In actual use, the magnitude of the disengagement force is related to the number of the connecting protrusions 51 and the connecting recesses 52.

[0056] Specifically, two first guide grooves 111 are symmetrically provided on the fork 11 ; two guide posts 21 are symmetrically provided on the periphery of the barrel 2 ; the rotation guide portion is a rotation guide groove 31 ; the guide post 21 passes through the first guide groove 111 and is placed in the rotation guide groove 31 .

[0057] In a specific implementation, a bayonet 112 is provided at the top and the tail of a single first guide groove 111 for fixing the barrel 2 rotated to the top or the bottom.

[0058] In a specific implementation, the fork 11 is rotated forward, and the rotating fork 11 drives the guide post 21 (that is, drives the barrel 2) to slide upward along the rotating guide groove 31 in a spiral manner. However, because the guide post 21 is limited by the first guide groove 111, the guide post 21 is vertically displaced upward along the first guide groove 111.

[0059] In a specific implementation, similar to the forward rotation, the fork 11 is rotated in the reverse direction to drive the guide post 21 (that is, drive the barrel 2) to slide downward along the first guide groove 111 under the cooperation of the first guide groove 111 and the rotation guide groove 31.

[0060] Specifically, the length of the fork 11 is longer than the length of the spiral 3, so as to ensure that the base 12 connected to the tail of the fork 11 is exposed outside the spiral 3, so as to facilitate hand-held twisting.

[0061] Specifically, the fork 11, the base 12, the barrel 2, the spiral 3 and the middle bundle tube 4 are all coaxially arranged.

[0062] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
