Description

Technical Field

[0001] The utility model relates to the technical field of medical beauty, and particularly relates to a micro-insertion hand-held beauty gun for medical beauty. Background Art

[0002] With the rapid development of the medical beauty industry, the micro-insertion hand-held beauty gun, as a new type of beauty tool, has been increasingly favored by the market. This device uses micro-needle technology to directly deliver beauty liquid to the deep layer of the skin, promoting skin absorption and improving skin problems. Its convenience, safety, and effectiveness make it a popular choice in beauty care.

[0003] However, the existing micro-insertion hand-held beauty guns have some technical defects.

The third square rod 133 is squeezed and drives the ring frame 132 to slide towards the cover plate 120, and the end of the piston rod is driven out accordingly. By inserting the injection port of the syringe into the circular hole 311, when the cover plate 120 is closed, the inner wall of the cover plate 120 will squeeze the square block 321, causing it to slide into the square groove 320. The square block 321 squeezes the arc-shaped frame 314 at the ring groove 313, and the arc-shaped frame 314 is squeezed, making the third seal 315 closely adhere to the outer wall of the injection port.

[0029] Embodiment 1

[0030] As Figure 4 and 6 As shown, in this embodiment, the port sealing mechanism 200 includes a first sealing unit 210 and a second sealing unit 220. The first sealing unit 210 includes a third square plate 211. A sliding groove 121 is formed on the inner wall of the cover plate 120, and the outer wall of the third square plate 211 is slidably inserted into the inner wall of the sliding groove 121. A second spring 213 is fixedly connected to the outer wall of the third square plate 211. One end of the second spring 213 is fixedly connected to the outer wall of a semi-ring frame 212. The outer wall of the semi-ring frame 212 is slidably inserted into the inner wall of the sliding groove 121. A first seal 215 is fixedly connected to the outer wall of the semi-ring frame 212. The second sealing unit 220 includes two fourth square rods 221. The outer walls of the fourth square rods 221 are fixedly connected to the internal frame of the housing 110. A semi-ring frame 222 is slidably inserted between the inner walls of the two fourth square rods 221. A third spring 223 is fixedly connected to the outer wall of the semi-ring frame 222. One end of the third spring 223 is fixedly connected to the outer wall of the square tube of the spring telescopic rod 131. A second seal 225 is fixedly connected to the outer wall of the semi-ring frame 222. The outer wall of the second seal 225 is inserted and matched with the piston rod, and the outer wall of the first seal 215 is inserted and matched with the piston rod.

[0031] In this embodiment, the electric telescopic rod inside the housing 110 drives the movement of the first driving ring frame 130 and the second driving ring frame 132, pushing the piston rod. During the pushing process, the third square plate 211 will contact the outer wall of the second ring frame 132, causing the second spring 213 and the third spring 223 to be squeezed by the thrust. The second spring 213 and the third spring 223 will then squeeze the first seal 215 and the second seal 225, making them closely adhere to the syringe port, preventing the gasket of the piston rod from being damaged and spraying out from the port into the interior of the housing 110, which not only pollutes the internal environment but may also damage non-waterproof components, effectively improving the port sealing performance. In addition, there is a small gap between the first seal 215 and the second seal 225 to facilitate the piston rod to push the liquid.

[0032] As Figure 3-4 shown, in this embodiment, on both inner wall positions of the rubber clamping block inside the housing 110 near the syringe, there are first square plates 111 fixedly connected. A wedge 112 is slidably inserted between the first square plate 111 and the inner frame of the housing 110. On one outer wall of the wedge 112, there is an arc-shaped plate 115 fixedly connected. On the inner wall of the cover plate 120, two first square rods 122 are fixedly connected at equal intervals on one side of the center.

[0033] During specific implementation, when a syringe filled with liquid needs to be placed inside the housing 110, the syringe is clamped on the rubber clamping block, and the cover plate 120 is covered, so that the first square rods 122 on the inner wall of the cover plate 120 contact the wedge 112. The wedge 112 is squeezed and slides to one side, causing the two arc-shaped plates 115 to closely adhere to the outer wall of the rubber clamping block, preventing it from falling off due to being squeezed during work, effectively improving the stability of the syringe.

[0034] Embodiment Two

[0035] As Figure 7 shown, in this embodiment, the injection port plugging mechanism 300 includes a square frame 310. At the center of the outer wall of the square frame 310, there is a circular hole 311. At the center of the inner wall of the circular hole 311, there is an annular groove 313. Between the outer wall of the square frame 310 at the circular hole 311 and one end outer wall of the atomizing nozzle, there is a water pipe 312 fixedly connected. Inside the annular groove 313, two arc-shaped frames 314 are slidably inserted at equal angles around its axis. Between the inner walls of the two arc-shaped frames 314, there is a third seal 315 fixedly connected. At both ends of one outer wall of the square frame 310, there are square grooves 320, and the square grooves 320 communicate with the annular groove 313. Inside the square grooves 320, there are square blocks 321 slidably inserted. Between the outer wall of the square block 321 and the inner wall of the square groove 320, there is a fourth spring 322 fixedly connected.

[0036] In specific implementation, the injection port of the syringe is inserted into the circular hole 311. When the cover plate 120 is closed, the inner wall of the cover plate 120 presses against the square block 321, causing it to slide into the square groove 320. The square block 321 presses against the arc-shaped frame 314 at the annular groove 313. The arc-shaped frame 314 is squeezed, causing the sealing member III 315 to closely adhere to the outer wall of the injection port, avoiding frequent insertion and extraction of the injection port and the pipe orifice of the water pipe 312, which may cause the pipe orifice to become larger and affect the sealing effect, thus effectively improving the sealing performance.
