[0019] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figure 1 As shown, a small cosmetic needle assembly includes a needle body 1. The needle body 1 has a contact seat 3, an injection cylinder 2, a sealing plug 9, and a connecting seat 10 sequentially connected from top to bottom. An injection cavity 7 is integrally formed at the bottom of the needle body 1. An outer wing plate 6 is fixedly connected to the outside of the injection cavity 7. A needle 8 is embedded inside the injection cavity 7. An anti-slip part 4 is provided on the surface of the needle body 1. An anti-slip layer 5 is fixedly connected to the surface of the anti-slip part 4. A flow guiding assembly 11 is fixedly connected inside the injection cavity 7. The flow guiding assembly 11 includes an upper flow guiding seat 12 and a lower flow guiding seat 13 fixedly connected. The surfaces of the upper flow guiding seat 12 and the lower flow guiding seat 13 are respectively provided with a first flow guiding groove 14 and a second flow guiding groove 15.
[0021] like Figure 1 As shown, the anti-slip part 4 is arranged in an arc-shaped concave shape along both sides of the needle holder body 1. The anti-slip layer 5 is arranged in a spiral distribution along the surface of the anti-slip part 4. The anti-slip layer 5 is raised as an anti-slip particle layer. The outer wing plate 6 is arranged in an arc-shaped flat shape. The injection cavity 7 is a rectangular chamber that is vertically opened. The position where it connects with the needle holder body 1 is conical. The flat outer wing plate 6 facilitates the user to limit and fix the bottom position of the needle holder body 1. The injection cavity 7, which is constricted, reduces the amount of external beauty liquid injected and ensures the accuracy of injection. The conical arrangement between it and the needle holder body 1 facilitates the limiting and support of the entire flow guide component 11.
[0022] like Figure 2 As shown, the sealing plug 9 is a rubber sealing plug, and the connecting seat 10 is a conical seat with a downward-facing opening. The sealing plug 9 and the connecting seat 10 work together to facilitate the injection of external beauty liquid.
[0023] like Figure 2-3 As shown, the flow guiding component 11 is vertically arranged. The upper flow guiding seat 12 is conical and located at the junction of the injection cavity 7 and the needle holder body 1. The lower flow guiding seat 13 is rectangular and vertically arranged. Its junction with the upper flow guiding seat 12 is also conical. There is a gap between the bottom of the lower flow guiding seat 13 and the bottom of the injection cavity 7. The first flow guiding groove 14 and the second flow guiding groove 15 are respectively vertically opened along the four edges of their respective upper flow guiding seat 12 and lower flow guiding seat 13. The first flow guiding groove 14 and the second flow guiding groove 15 are distributed vertically and vertically. The upper flow guiding seat 12 facilitates the overall support and fixation of the flow guiding component 11 within the injection cavity 7 and the needle holder body 1. The lower flow guiding seat 13, the first flow guiding groove 14, and the second flow guiding groove 15 reduce the amount of external beauty liquid injected into the injection cavity 7, achieving the effect of precise and appropriate injection.
[0024] During the injection procedure, the user pushes the syringe 2, sealing plug 9, and connecting seat 10 down along the needle holder body 1, pushing the beauty solution into the flow guide assembly 11 and the injection chamber 7, and then outward from the needle 8 to complete the injection. During this process, the beauty solution is stored between the needle holder body 1 and the injection chamber 7. When the sealing plug 9 and connecting seat 10 are pushed down, the beauty solution is squeezed and transported along the two sets of flow guide grooves opened on the surfaces of the upper flow guide seat 12 and the lower flow guide seat 13 to the bottom space of the injection chamber 7, and then discharged from the needle 8 to complete the injection. This process can effectively further reduce and control the injection volume, achieve precise injection, and avoid excessive residue of beauty solution.
[0025] The working principle of this utility model is as follows: When this device is in use, the flow guiding component 11 ensures the amount of beauty liquid used while reducing the injection volume, thereby achieving precise injection and avoiding excessive residue of beauty liquid. At the same time, during operation, the outer wing plate 6 and the anti-slip layer 5 ensure the overall operational stability of the device.
[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
