Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a multifunctional high-pressure air gun for oral cavity. Background Art

[0002] Existing dental instruments must undergo a rigorous disinfection process to ensure safety during clinical use. This process includes recycling, pre-treatment, initial cleaning, multi-enzyme cleaning, rinsing, final rinsing, ultrasonic cleaning, high-pressure air gun drying, secondary drying in a fully automatic dryer, packaging, disinfection and sterilization, and sterile storage. High-pressure air gun drying is a crucial step in this process, using a high-pressure air gun to control water flow and dry the instruments, effectively blocking the breeding ground for bacteria. Currently, common high-pressure air guns in clinical practice primarily feature a single main body and eight different air outlet shapes. Common issues include: 1. Existing high-pressure air guns often use a trigger to control the switch, requiring a finger to continuously press the trigger for continuous air flow; 2. Existing technologies utilize nozzles (air outlets) of varying shapes to meet varying air flow requirements. These nozzles are separate components that require constant disassembly and installation, creating a cumbersome process. In summary, due to one or more of these design deficiencies, traditional high-pressure air guns fail to fully meet clinical needs, impacting user experience and reducing work efficiency.

[0003] Therefore, it is necessary to provide a multifunctional oral high-pressure air gun to solve the above problems. Utility Model Content

[0028] Please refer to Figure 1-4 As shown, a multifunctional oral high-pressure air gun includes a gun body 1. The outlet end of the gun body 1 (or the air outlet or water outlet of the high-pressure air gun) is provided with a socket-fitting mounting seat 112 and a rotating disk 113. The mounting seat 112 and the rotating disk 113 can be matched using an existing socket-locking limiting mechanism. The rotating disk 113 is circumferentially arranged on one side not connected to the mounting seat 112 with at least two groups of gun nozzles 1131 of different shapes. The rotating disk 113 can be circumferentially rotated, axially limited within the mounting seat 112, and the gun nozzles 1131 can be switched by rotation. In this way, this solution is similar to the shower head adjustment structure used in daily showers, where the water outlet has multiple adjustable modes. The high-pressure air gun body is equipped with multiple air outlet modes. Users can adjust the high-pressure air gun according to different air supply needs without repeated disassembly and assembly. At the same time, the gun body 1 is also provided with a pull button mechanism 13 for controlling the opening and closing of the gun body 1. That is, a switch button is provided on the main body of the high-pressure air gun, and the air supply can be turned on and off to start and stop the air supply, freeing your hands. This solution mainly makes structural improvements and upgrades in the two aspects of the switch method and the air outlet switching mode.

[0029] Based on the above technical solution, the gun body 1 includes a barrel portion 11 and a grip portion 12. The mounting seat 112 defines a first channel 111 within the barrel portion 11 and a second channel 121 within the grip portion 12. One end of the first channel 111 communicates with the second channel 121, and the other end of the first channel 111 communicates with the mounting seat 112. Specifically, the grip portion 12 is provided with the aforementioned knob mechanism 13 along the direction of the barrel portion 11. The knob mechanism 13 includes a knob member 131, a pull rod member 1312, and a spring member 133. One end of the pull rod member 1312 is connected to the knob member 131, and the other end is provided with a rotating piece 1321. The rotating piece 1321 is disposed in the second channel 121 and is used to adjust the opening and closing of the second channel 121, thereby causing the knob member 131 and the pull rod member 1312 to cooperate with each other to control the opening and closing of the air gun. More specifically, the rotating piece 1321 rotates under the regulation of the button member 131 and the pull rod member 1312 to open the second channel 121 or close the second channel 121 to realize air supply and stop air supply (or water supply).

[0030] In an optional embodiment, a circular groove 1121 is provided at the mounting seat 112 corresponding to the rotating disk 113, and a clamping portion 1132 is provided at the rotating disk 113. The outlet end of the first channel 111 is arranged at the bottom of the circular groove 1121, and the outlet end of the first channel 111 corresponds to the inlet end of the nozzle piece 1131 on the rotating disk 113. The clamping portion 1132 is limited to the circular groove 1121 and is movably connected, so that the rotating disk 113 is limited to the mounting seat 112 and can be rotatably adjusted.

[0031] Specifically, the gun nozzle piece 1131 is configured as a water gun head, an air gun head, or a shower head, and the water gun heads, the air gun heads, or the shower heads are sequentially arranged along the circumference of the upper surface of the rotating disk 113 .

[0032] On this basis, a hook portion 2 is provided on the gun body 1 for hanging.

[0033] Furthermore, a connecting port 122 is provided at the bottom end of the gun handle 12, and the connecting port is used to connect to an external air supply or water supply equipment. The second channel 121 is connected to the connecting port 122, and the outer wall of the connecting port 122 is provided with an external thread 1221 for connecting to an external pipe. The external thread 1221 mainly has an internal thread for connecting to the air or water inlet.

[0034] Thus, in a preferred embodiment, the button mechanism 13 further includes a receiving chamber 134, in which the button member 131, the pull rod member 1312 and the spring member 133 are all disposed. The receiving chamber 134 can cooperate to complete the functions of fixing the button mechanism and preventing dust.

[0035] In order to increase friction and facilitate adjustment operation, the button member 131 is configured in a cross shape, which can also make the overall surface of the button mechanism 13 beautiful and simple.

[0036] For the same purpose, the rotating disk 113 is preferably provided with tooth-shaped protrusions 1133 on the outer peripheral wall. Preferably, multiple tooth-shaped protrusions 1133 are arranged circumferentially with the same spacing to increase friction and adjustment accuracy.

[0037] Furthermore, a corresponding number of sealing members 3 are provided at the inlet end of the nozzle piece 1131 to ensure the sealing performance of the nozzle piece 1131 .

[0038] The multifunctional oral high-pressure air gun provided in this application brings at least the following beneficial effects:

[0039] 1. The utility model can easily switch different nozzle parts by adjusting the rotating disk to achieve different air or water outlet modes. It can switch various nozzles without disassembling different nozzle accessories. The air outlet or water outlet modes are diverse and can be easily adjusted and switched on the main body. It has a simple structure and convenient operation, which greatly improves the user experience.

[0040] 2. Compared with the existing handle control structure, the pull button mechanism of the present application can better free both hands and is beautiful and simple, greatly improving the comfort of use and being more popular.

[0041] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
