Description

Technical Field

[0001] This utility model relates to the field of plastic equipment technology, and in particular to a plastic booster device. Background Technology

[0002] Needle-free injection is a technique that uses high-pressure, high-speed airflow or mechanical power to directly deliver medications or cosmetic ingredients into the skin or subcutaneous tissue, eliminating the need for traditional needle punctures. In the field of aesthetic medicine, it has gained increasing attention due to its "non-invasive and low-pain" characteristics. The mesotherapy booster device, used to connect to the non-invasive injector, is the main driving and control device for non-invasive injection.

[0003] The existing Meso booster device includes a switching valve, a firing mechanism, and an air intake mechanism. The air intake mechanism is connected to the firing mechanism through the switching valve. The operator controls the high-pressure gas in the air intake mechanism to enter the firing mechanism through the switching valve. The firing pin of the firing mechanism rushes into the non-invasive injector, providing instantaneous pressure to the non-invasive injector and ejecting the active ingredient in the non-invasive injector at high speed.

[0004] The existing cosmetic booster device has the following disadvantages: (1) High-pressure gas enters through a single air hole on one side of the cylinder, causing uneven force on the impact pin, which can easily damage the impact pin and the speed of the effective ingredients of the non-invasive syringe cannot meet the requirements; (2) The existing switch valve directly controls the opening and closing of the air passage through the valve core. The air passage opening process requires the valve core to apply a large thrust, which is easy to deviate during operation and affect the cosmetic effect. Utility Model Content

The sealing end is used to control the connection between the gas delivery port and the gas source inlet or the gas outlet. The drive ring is located outside the sleeve cavity and abuts against the side wall of the valve cavity.

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0032] See Figures 1 to 5 As shown, this utility model embodiment provides a plastic booster device, including a first air chamber 1, a second air chamber 2, a piston assembly 3, and a trigger 5.

[0033] This embodiment of the invention improves the structure of the control valve 4 and the second air chamber 2, thereby reducing the operational difficulty and improving the operational accuracy of the Meisu booster device.

[0034] Specifically, the first gas chamber 1 is provided with a gas source inlet 11, a gas outlet 13, a gas delivery port 12, and a control valve 4. When the trigger 5 presses the control valve 4, the control valve 4 blocks the connection between the gas delivery port 12 and the gas outlet 13; when the trigger 5 is released, the control valve 4 blocks the connection between the gas delivery port 12 and the gas source inlet 11.

[0035] The second air chamber 2 is provided with a piston assembly 3, which includes a piston 31 and a striking pin 32. The striking pin 32 is disposed on the piston 31. The second air chamber 2 is provided with a plurality of working air holes 21 at predetermined intervals at one end near the piston 31. The plurality of working air holes 21 are connected to the gas delivery port 12. An elastic element 22 is provided between the piston 31 and the striking pin output end of the second air chamber 2.

[0036] Working principle of this utility model embodiment:

[0037] When trigger 5 is pressed, control valve 4 blocks the connection between gas inlet 12 and gas outlet 13. At this time, gas inlet 12 is only connected to gas source inlet 11, and high-pressure gas enters working port 21 through gas inlet 12. Since working ports 21 are set at predetermined intervals in the second chamber 2, high-pressure gas can evenly fill the space between piston 31 and the end of the second chamber 2, thereby activating the firing pin. When trigger 5 is released, control valve 4 blocks the connection between gas inlet 12 and gas source inlet 11. At this time, gas inlet 12 is connected to gas outlet 13, and high-pressure gas in the second chamber 2 is quickly discharged. Under the action of the elastic element, the piston quickly returns to its original position.

[0038] Firstly, this invention incorporates a control valve 4 within the first gas chamber 1. By pressing the control valve 4 with the trigger 5, the control valve 4 connects the gas delivery port 12 to the gas source input port 11 or the gas outlet 13. This results in a faster terminal velocity of the impact pin 32, enabling the achievement of predetermined process requirements with lower air pressure. It also reduces the requirements for auxiliary equipment and is easy to operate.

[0039] Secondly, the second air chamber 2 has multiple working air holes 21 spaced at predetermined intervals at one end near the piston 31, and these working air holes 21 are connected to the gas delivery port 12. Because the second air chamber 2 has multiple working air holes 21, when the trigger 5 is pressed, high-pressure gas can enter through these holes, resulting in uniform gas pressure at the piston 31 and thus uniform force distribution. This ensures stable impact activation, effectively reducing the probability of damage to the firing pin 32 and increasing the firing pin speed.

[0040] In the existing MISU booster device, during the reset process, the output end of the second air chamber 2 is prone to low pressure or vacuum, which hinders the reset speed and smoothness of the impact.

[0041] Preferably, it also includes a front cover 6 for the firing pin, which is disposed at the firing pin output end of the second air chamber 2;

[0042] The front cover 6 of the firing pin includes a cover body 61 and a firing pin guide tube 62. The firing pin guide tube 62 is disposed on the cover body 61, and the firing pin 32 can extend into the firing pin guide tube 62. Both the side walls of the cover body 61 and the firing pin guide tube 62 are provided with air guide holes 63.

[0043] First, both the cover 61 and the side wall of the striker guide tube 62 are provided with air guide holes 63. During the reset process of the striker 32, external air can enter the second air chamber 2 through the air guide holes 63 to ensure that the air pressure at both ends of the piston 31 is kept balanced and to improve the smoothness of the reset of the striker 32.

[0044] Secondly, the firing pin guide tube 62 guides the stroke of the firing pin 32 and facilitates connection with the matching needleless injector.

[0045] Preferably, both the cover 61 and the second air chamber 2 are provided with buffer pads 22 at the ends near the piston 31. The buffer pads 22 at the cover 61 and the second air chamber 2 buffer the impact of the firing pin 32, thereby extending the service life of the firing pin 32.

[0046] In some embodiments, the gun body 8 with a valve chamber 7 is also included, wherein the control valve 4 is disposed in the valve chamber 7 and includes a movable valve element 41, a valve core element 42, a ejector pin 44 and a valve cover 43;

[0047] The movable valve 41 includes a sealing end 411, a sleeve cavity 412, a drive ring 413, and a first air passage 414 that connects the top surface of the movable valve 41 to the sleeve cavity 412. The sealing end 411 is used to control the gas delivery port 12 to connect with the gas source input port 11 or the gas outlet port 13. The drive ring 413 is located outside the sleeve cavity 412 and abuts against the side wall of the valve cavity 7.

[0048] The valve core 42 is fixedly disposed in the valve cavity 7, including a valve core column 421 and a valve core seat 422. The valve core column 421 is disposed in the center of the valve core seat 422 and sleeved in the sleeve cavity 412. The valve core 42 has a second air passage 423 that connects the top surface of the valve core column 421 to the bottom surface of the valve core seat 422. The valve core seat 422 has a third air passage 424 that connects its upper surface and bottom surface.

[0049] The valve cover 43 is located at the bottom of the valve cavity 7. The ejector pin 44 extends through the bottom of the valve cover 43 and is able to move relative to the valve cover 43. The ejector pin 44 can be driven by the trigger 5 to seal the second air passage 423.

[0050] During operation, pressing the trigger 5 causes the ejector pin 44 to block the second air passage 423. High-pressure gas cannot enter the space between the valve core seat 422 and the sleeve cavity 412 from the second air passage 423, and the high-pressure gas in the valve cavity 7 flows out from the gap between the ejector pin 44 and the valve cover 43. At this time, the air pressure at both ends of the moving valve 41 is unbalanced, and it moves rapidly towards the valve cover 43, thereby causing the sealing end 411 to block the connection between the gas delivery port 12 and the gas outlet 13. When the trigger 5 is released, the second air passage 423 connects to the gas source inlet 11 through the first air passage 414, and the high-pressure gas flows through the second air passage 423 to the space between the valve core seat 422 and the sleeve cavity 412. After the ejector pin 44 resets, it seals the gap between itself and the valve cover 43, and the high-pressure gas cannot flow out, causing the air pressure at both ends of the moving valve 41 to change, and the moving valve 41 moves to the position that blocks the connection between the gas delivery port 12 and the gas source inlet 11. At this time, the gas inlet 12 is connected to the gas outlet 13, and the high-pressure gas in the second gas chamber 2 is quickly discharged.

[0051] More preferably, the valve chamber 7 includes an upper valve chamber and a lower valve chamber that are interconnected, and the traveling valve 41 is located in the upper valve chamber; a stepped portion is provided at the junction of the upper valve chamber and the lower valve chamber, and the valve core seat 422 is pressed onto the stepped portion by the valve cover 43.

[0052] The upper and lower valve chambers are designed so that the moving valve 41, valve core 42, ejector pin 44 and valve cover 43 can be installed into the valve chamber 7 in sequence. The moving valve 41 moves in the upper valve chamber, while the valve core 42 is fixed in the predetermined position of the valve chamber 7. The moving valve 41, valve core 42 and valve cover 43 are all sealed with the valve chamber 7 to prevent gas from escaping from the gap between the moving valve 41, valve core 42 and valve cover 43 and the valve chamber 7.

[0053] More preferably, the bottom of the movable valve 41 is provided with a first gas cavity 45, the valve cover 43 is provided with a second gas cavity 46, the ejector pin 44 is located in the second gas cavity 46, and the first gas cavity 45 is connected to the second gas cavity 46 through a third gas passage 424. It should be noted that when the ejector pin 44 releases the blockage of the second gas passage 423, high-pressure gas flows sequentially from the first gas passage 414, the second gas passage 423, the third gas passage 424, the second gas cavity 43, and the first gas cavity 45. Therefore, the air pressure will push the movable valve 41 towards the first gas chamber 1. When the ejector pin 44 blocks the second gas passage 423, the high-pressure gas in the first gas cavity 45 flows from the third gas passage 424 to the second gas cavity 46, and then flows out from the gap between the ejector pin 44 and the valve cover 43, causing the air pressure in the first gas cavity 45 to drop rapidly, and the movable valve 41 moves towards the valve cover 43.

[0054] More preferably, the end of the ejector pin 44 located inside the valve cover 43 is a tapered portion, and the second air passage 423 has a tapered groove on the contact end with the ejector pin.

[0055] In some embodiments, one end of the ejector pin 44 located outside the gun body 8 is connected to the trigger 5, and a trigger reset elastic element 51 is sleeved on the portion of the ejector pin 44 located outside the gun body 8; one end of the trigger reset elastic element 51 is connected to or abuts against the trigger 5, and the other end is connected to or abuts against the gun body 8. The trigger reset elastic element 51 is provided between the trigger 5 and the gun body to assist in quickly resetting the trigger 5 when it is released.

[0056] In some embodiments, the sidewall at the sealing end 411 is provided with a first sealing element 415 and a second sealing element 416, and there is a predetermined distance between the first sealing element 415 and the second sealing element 416, and the driving ring 413 is a third sealing element.

[0057] The outer wall of the valve core column 421 is provided with a fourth sealing element 425, which abuts against the inner wall of the sleeve cavity 412. The outer wall of the valve core seat 422 is provided with a fifth sealing element 426, which abuts against the inner wall of the valve cavity 7.

[0058] The outer wall of one end of the ejector pin 44 located inside the valve cover 43 is provided with a sixth sealing element 441. The sixth sealing element 441 can abut against the bottom of the valve cover 43 to seal the gap between the ejector pin 44 and the valve cover 43.

[0059] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
