Detailed Implementation

[0019] 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.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-4A non-invasive body thruster assembly structure includes a cylinder body 1, a cylinder rear cover 2, and a rear air intake ring 3. The cylinder rear cover 2 is installed at one end of the cylinder body 1, and the rear air intake ring 3 is installed on the cylinder rear cover 2. A first air hole 4 is opened on the cylinder body 1, a second air hole 5 is opened on the rear air intake ring 3, and a third air hole 6 is opened on the cylinder rear cover 2. A push rod 9 is slidably installed inside the cylinder body 1, and an installation bracket 11 is installed at the other end of the cylinder body 1. A limit bracket 12 is installed on the installation bracket 11, and a rod sleeve 13 is slidably installed inside the limit bracket 12. The rod sleeve 13 is slidably fitted on the outside of the push rod 9, and an ampoule head 14 is installed at the end of the rod sleeve 13.

[0022] A rear shock absorber 7 is installed inside the cylinder rear cover 2. A compression spring 8 is installed on the rear shock absorber 7, and the compression spring 8 is connected to one end of the push rod 9. A front shock absorber 10 is installed on the outer side of the other end of the push rod 9 inside the cylinder body 1.

[0023] The limiting frame 12 has sliding grooves 15 on both sides, and the rod sleeve 13 has protrusions 16 on both sides that move along the sliding grooves 15. The mounting bracket 11 is equipped with an adjusting motor 18, and the adjusting motor 18 is equipped with a threaded rod 19. The threaded rod 19 is threadedly connected to the adjusting block 17 on the bottom side of the rod sleeve 13. The adjusting motor 18 drives the threaded rod 19 to rotate, which cooperates with the threaded adjusting block 17 to drive the rod sleeve 13 to move along the sliding grooves 15 through the protrusions 16, thereby achieving fine adjustment of the ampoule head 14.

[0024] The first air port 4 of the cylinder body 1 and the second air port 5 of the rear air intake ring 3 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.

[0025] Working principle: The control switch of 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 second air hole 5 of the rear air intake ring 3 and the third air hole 6 of the cylinder rear cover 2, the push rod 9 is pushed out of the cylinder body 1. At the same time, the compression spring 8 undergoes elastic deformation. The push rod 9 acts on the ampoule head 14 to inject air. When air enters through the first air hole 4 of the cylinder body 1, the push rod 9 is pushed to retract into the cylinder body 1. The compression spring 8 undergoes elastic deformation to retract the piston movement inside the ampoule head 14. The operation of the adjusting motor 18 drives the threaded rod 19 to rotate. It cooperates with the threaded adjusting block 17 to drive the rod sleeve 13 to move along the slide groove 15 through the protrusion 16, thereby realizing the fine adjustment of the ampoule head 14.

[0026] 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 adapts to different skin depths and injection medium viscosities, adjusts the motor's operation, achieves a propulsion resolution of 10μm, precisely controls gas release and injection depth, and maintains a pressure fluctuation range of ≤±2%, avoiding tissue damage or uneven injection caused by sudden pressure increases. The built-in micro air pump and gas storage chamber are integrated, eliminating reliance on external gas cylinders. It is ergonomically designed for one-handed operation 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.

[0027] 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.
