DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Example 1

[0030] Reference Figure 1-5 The pen comprises: a cosmetic pen body 1, a pen cap 2 and a fixing component.

[0031] The cosmetic pen body 1 is composed of a pen holder 3 and a pen tip 6. The pen holder 3 is provided with a liquid storage cavity for storing cosmetic liquid. A tail plug 4 is installed at one end of the pen holder 3 to seal the liquid storage cavity. The pen cap 2 is used to cover the pen tip 6 to protect the pen tip 6 from damage or contamination. The cosmetic pen body 1 and the pen cap 2 are both made of antistatic polymer materials, which can effectively reduce the generation and accumulation of static electricity, and also have good durability.

[0032] The fixing assembly includes a mounting tube 9 fixedly mounted on one end of the pen body 3. The outer wall of the mounting tube 9 is provided with two through grooves 11, which enhance the deformability of the mounting tube 9 and make it easier to install and remove the pen tip 6. The pen tip 6 includes a mounting portion 13 and a nib portion 14, and the outer wall of the nib portion 14 is provided with a plurality of sealing rings 8. The inner wall of the mounting tube 9 is provided with grooves that match the sealing rings 8. When the nib portion 14 is inserted into the mounting tube 9, the sealing ring 8 is tightly matched with the groove to form an effective sealing structure.

[0033] Further, in order to fix the nib 6, the outer wall of the mounting tube 9 is also provided with threads, and is sleeved with an internal threaded sleeve 10. By rotating and installing the internal threaded sleeve 10, it can be tightly threadedly connected with the mounting tube 9, thereby tightening the mounting tube 9 and further fixing the nib 6.

[0034] A liquid outlet pipe is provided inside the mounting portion 13 and the pen tip portion 14 for draining the cosmetic liquid. A conical groove 15 is provided at one end of the mounting portion 13 to match the conical protrusion 7 at one end of the pen holder 3. A liquid outlet hole is provided inside the conical protrusion 7 to communicate with the liquid outlet pipe to ensure that the cosmetic liquid can flow out smoothly. At the same time, a ring gasket is provided at the end of the mounting portion 13 that contacts the pen holder 3 to enhance the sealing effect.

[0035] The present application can be used in the field of beauty product technology, and can also be used in other fields applicable to the present application.

[0036] Example 2

This design makes the cosmetic brush body 1 less likely to roll when placed on a plane, thereby increasing stability.

[0042] The working principle and use process of the technical solution are as follows: when using, the user takes off the pen cap 2, and the cosmetic liquid can be discharged from one end of the pen tip 14, which is convenient for the user to use; when the user finishes using, he only needs to insert one end of the pen tip 14 into the pen cap 2 again, and the pen cap 2 can be fixed by using the cooperation of the annular protrusion 16, the annular groove 17 and the sealing ring, and one end of the pen tip 14 abuts against the liquid storage tube 5, which can seal one end of the pen tip 14 and collect the overflowed cosmetic liquid; the cosmetic pen is provided with a plurality of sealing rings 8 on the outer wall of the mounting portion 13, which can cooperate with the grooves provided in the mounting tube 9, The pen tip 6 is fixed and sealed. At the same time, an annular gasket is provided at one end of the mounting portion 13 to ensure that it is tightly attached to one end of the pen holder 3 to ensure a good sealing effect. Two through grooves 11 are provided on the mounting tube 9 to enhance the deformation ability of one end of the mounting tube 9, which is conducive to the installation of the pen tip 6. The outer wall thread sleeve of the mounting tube 9 is provided with an internal threaded sleeve 10, which can tighten the mounting tube 9, so that the mounting tube 9 can stably clamp and fix the pen tip 6 to ensure a good use effect. The cosmetic pen is provided with hexagonal protrusions on the outer walls of the ring 12 and the tail plug 4 to ensure that the cosmetic pen can be stably placed on a plane and is not prone to rolling.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
