[0030] In the present embodiment, a section of the connecting tube 316 is connected to the upper portion of the mounting tube 6, and the gas flow sensor 313 is electrically connected to the display screen 314. Through the cooperation of the gas flow sensor 313, the display screen 314, the first air inlet pipe 311, and the second air inlet pipe 317, the gas added to the fuselage 1 can be quantitatively adjusted, thereby increasing the applicability of the device, and dangerous gases can be added to the fuselage 1 through the first air inlet pipe 311, and gases containing impurities and non-hazardous gases can be aerated through the second air inlet pipe 317, thereby further increasing the applicability of the device.

[0031] Furthermore, one end of the first spring 3117 is fixedly connected to the slider 3116, the bottom of the limiting rod 3118 is fitted with the outside of the mounting frame 319, and the sealing ring 3110 is arranged at the gap between the mounting frame 319 and the processing box 315.

When the introduced gas reaches the set value, the second air intake control valve 318 is closed to complete the gas filling operation. Furthermore, when it is necessary to disassemble the mounting frame 319, it is only necessary to manually push the limit rod 3118 to move the limit rod 3118 away from the upper part of the mounting frame 319, and then the mounting frame 319 can be manually taken out upward, thereby facilitating manual cleaning of the first filter plate 3111, the second filter plate 3112, and the third filter plate 3113, thereby achieving a better filtering effect on air and other gases.

[0034] Based on Example 1, a preferred embodiment of a gas mixing supply device that is easy to adjust provided by the utility model is as follows: Figures 1 to 5As shown: the stirring mechanism 32 includes a motor 321 fixedly installed on the upper part of the fuselage 1 through a mounting frame, the output end of the motor 321 is fixedly connected to a rotating shaft 322, the outer sleeve of the rotating shaft 322 is provided with a mounting sleeve 323, the outer wall of the mounting sleeve 323 is fixedly connected to a stirring blade 324, the surface of the stirring blade 324 is provided with a through hole, the outer wall of the mounting sleeve 323 is fixedly connected to a pressing rod 325 through a rotating rod, a pressing ring 326 is fixedly installed on the top of the inner wall of the fuselage 1, a first mounting ring 327 is fixedly connected to the bottom of the mounting sleeve 323, a second mounting ring 3210 is fixedly connected to the bottom end of the rotating shaft 322, a connecting column 328 is fixedly connected to the upper part of the second mounting ring 3210, the top of the connecting column 328 is fixedly connected to a limiting block, and a second spring 329 is fixedly connected to the upper part of the second mounting ring 3210.

[0035] In this embodiment, the rotating shaft 322 is rotatably connected to the fuselage 1 through a bearing, the first mounting ring 327 is slidably connected to the outer wall of the connecting column 328, and the top of the second spring 329 is fixedly connected to the first mounting ring 327. Through the cooperation of the rotating shaft 322, the mounting sleeve 323, the stirring blade 324, the pressure rod 325, the pressure ring 326, the first mounting ring 327, the second mounting ring 3210, the second spring 329, and the connecting column 328, the stirring blade 324 can reciprocate up and down during the rotation process, so that the stirring effect of the stirring blade 324 can be better, and then the mixing effect of the gas can be better.

[0036] Furthermore, there are four connecting columns 328 equidistantly distributed on the upper portion of the second mounting ring 3210 .

[0037] When the gas needs to be mixed, the motor 321 drives the rotating shaft 322 to rotate, and under the action of the connecting column 328, the first mounting ring 327, and the second mounting ring 3210, the mounting sleeve 323 can be rotated synchronously, and then the stirring blade 324 fixedly connected to the outer wall of the mounting sleeve 323 can be rotated. By rotating the mounting sleeve 323, the pressure rod 325 and the pressure ring 326 can be pressed against each other. Through the elastic force of the second spring 329, the mounting sleeve 323 can be reciprocated up and down, so that the stirring effect of the stirring blade 324 can be better, and then the gas mixing effect can be better. By opening a through hole on the surface of the stirring blade 324, the stirring resistance can be reduced and the gas mixing can be accelerated. Then, the mixed gas can be supplied under the action of the outlet pipe 4 and the outlet control valve 5.
