[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] See Figures 1-5 A non-invasive facial pusher assembly structure includes a cylinder rear cover 1, a cylinder body 2, and a push rod 8. The cylinder rear cover 1 is detachably installed on the cylinder body 2. The push rod 8 is slidably installed inside the cylinder body 2, and the outer end of the push rod 8 protrudes from the cylinder body 2. An air intake ring 3 is installed on the outer side of the cylinder rear cover 1. A first air intake hole 4 is opened on the air intake ring 3. Several second air intake holes 5 are opened on the outer side of the cylinder rear cover 1 and inside the air intake ring 3. The second air intake holes 5 are opened on the cylinder body 2. A sealing protrusion 12 is provided in the middle of the push rod 8. The second air intake holes 5 and the third air intake holes 10 are respectively located at both ends of the sealing protrusion 12.

[0024] The cylinder rear cover 1 has an internal thread on the inner side of its end, and the cylinder body 2 has an external thread on the outer side of one end. The cylinder rear cover 1 and the cylinder body 2 are connected by threads, which facilitates the disassembly and assembly of the cylinder rear cover 1 and the cylinder body 2.

[0025] The other end of the cylinder body 2 has an internal thread, and the cylinder body 2 is threadedly connected to the ampoule head, which facilitates the disassembly and replacement of the ampoule head.

[0026] A rear shock absorber 6 is installed inside the cylinder rear cover 1. A mounting protrusion 11 is provided at one end of the push rod 8. A compression spring 7 is installed between the rear shock absorber 6 and the mounting protrusion 11. A front shock absorber 9 is fitted on the outer side of the other end of the push rod 8 to limit and fix the compression spring 7. At the same time, the rear shock absorber 6 and the front shock absorber 9 reduce the vibration frequency of the push rod 8 during operation.

[0027] The first air intake hole 4 of the air intake ring 3 and the third air intake hole 10 of the cylinder body 2 are connected to the micro air pump through pipes. The built-in micro air pump is integrated with the air storage chamber, eliminating the dependence on external air tanks. Injection is achieved through changes in internal air pressure.

[0028] A handle 13 is installed on the outside of the cylinder body 2, and a fourth air inlet 14 is opened on the handle 13, which communicates with the third air inlet 10.

[0029] The control switch for the miniature air pump is located on the outside of the gun body. When the miniature air pump is started by controlling the switch, when air enters through the first air inlet 4 of the air inlet ring 3 and the second air inlet 5 of the cylinder rear cover 1, the push rod 8 is pushed out of the cylinder body 2. At the same time, the compression spring 7 undergoes elastic deformation, and the injection is completed by the piston moving inside the ampoule head. When air enters through the third air inlet 10 of the cylinder body 2, the push rod 8 is pushed to retract into the cylinder body 2. The compression spring 7 undergoes elastic deformation, and the piston moving inside the ampoule head is retracted.

[0030] By optimizing pressure control and gun structure design, a safe, precise, and portable gas propulsion technology is achieved, reducing operational complexity and minimizing the risk of tissue damage. It is adaptable to different skin depths and injection medium viscosities, with a pressure fluctuation range of ≤±2%, avoiding sudden pressure increases that could lead to tissue damage or uneven injection. The built-in micro-pump and gas storage chamber are integrated, eliminating reliance on external gas canisters. It can be operated with one hand, conforming to ergonomics and suitable for delicate facial procedures. The detachable gas storage module facilitates replacement and sterilization, breaking through the limitations of traditional open-loop pneumatic systems to achieve high-precision, low-damage gas propulsion.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
