[0031] The pressure setting module 200 includes an adjustment disc 210, an indicator disc 220, a screw knob 230, a compression spring 240, and a (transparent) light guide mounting disc 250. The adjustment disc 210 is mounted on the adjustment disc mounting base 111, and the light guide mounting disc 250 is fixedly mounted (by bolts) on the light guide mounting base 112. The light guide mounting disc 250 is surrounded by the adjustment disc 210. The bottom of the light guide mounting disc 250 is provided with a first light guide post 251 and a second light guide post 252, and the top outer ring of the light guide mounting disc 250 is a display aperture ring 253. The label disk 220 (plug-in) is installed on the top of the light guide mounting disk 250, and the display aperture 253 is located between the adjustment disk 210 and the label disk 220. The adjustment disk 210 is provided with a first tilting block 211. The screw 230 and the compression spring 240 are both built into the compression spring channel 113.

The first end of the elastic element 330 is fixedly installed at the bottom of the first end of the first detection plate 310 (i.e., the side near the base), and the elastic element 330 has a first contact end 331 in the middle. The other end of the compression spring 240 passes through the first detection plate 310 and is close to the top of the first contact end 331. The protruding end 351 is located at the bottom of the first contact end 331. The second detection plate 320 is fixedly installed at the bottom of the second end of the first detection plate 310, and the second end of the elastic element 330 is located between the first detection plate 310 and the second detection plate 320.

[0033] The display module 400 includes a display circuit board 410, a first display lamp 420, and a second display lamp 430. The display circuit board 410 is electrically connected to the first detection board 310, and both the first display lamp 420 and the second display lamp 430 are mounted on the display circuit board 410. The first display lamp 420 is located below the first light guide post 251, and the second display lamp 430 is located below the second light guide post 252. (Different pressure states are displayed by lighting different display lamps. When the first or second display lamp is lit, the light emitted by it is transmitted to the display aperture through the corresponding upper light guide post and the reflective surface provided in the light guide mounting plate. The light from the first and second display lamps each displays half a circle on the display aperture.)

[0034] Specifically, the adjustment disc 210 is provided with an indicator mark, and the indicator disc 220 is provided with several pressure marks (by rotating the adjustment disc, the indicator mark is turned to the corresponding pressure mark, thereby completing the pressure setting).

[0035] More specifically, the second end of the first detection plate 310 is provided with a second contact end 311 at the bottom of the second end, and the second detection plate 320 is provided with a third contact end 321 on the side close to the first detection plate (which outputs a corresponding pressure state by contacting the second end of the elastic member).

[0036] Furthermore, the first detection board 310 is provided with a first connection end 312, a second connection end 313 and a third connection end 314. The first connection end 312 is installed on the first connection end mounting base 114, the second connection end 313 is installed on the second connection end mounting base 115, and the third connection end 314 is installed on the third connection end mounting base 116.

[0037] Furthermore, the first connection end 312, the second connection end 313, and the third connection end 314 are all covered by protective covers 315.

[0038] Preferably, the top inner ring of the adjustment disk 210 is provided with a limiting groove 212, and the display aperture 253 is pressed into the limiting groove 212 (so that the adjustment disk is stably located between the adjustment disk mounting base and the light guide mounting disk, and its top is limited by the light guide mounting disk and will not detach from the adjustment disk).

[0039] Preferably, the display module is modular and is installed on the first detection board via plug-in, so it can be selectively installed or replaced according to customer needs, and disassembly and assembly are quick and convenient.

[0040] Regarding this utility model:

[0041] First, by rotating the adjustment dial, the indicator is turned to the corresponding pressure mark. While the adjustment dial is rotating, the first tilting block drives the second tilting block to move (up or down depending on the direction of rotation), thereby adjusting the compression degree of the screw knob between the spring and the first contact end (the compression degree of the spring matches the corresponding gas pressure), thus completing the pressure setting. In this state, the second end of the elastic element is connected to the third contact end of the second detection plate. Through the preset wiring between the detection plate and the display circuit board, the first connection end and the third connection end are connected, thereby outputting that the current gas pressure has not yet reached the pressure setting value, and this is displayed intuitively by the first indicator light.

[0042] When gas is introduced into the intake connection channel and the pressure gradually increases, the gas accumulates in the intake area and then exerts an upward force on the main diaphragm, causing the convex end of the tray to move upward and touch the first contact end. When the gas pressure is greater than the set value, the force exerted by the convex end on the first contact end is greater than the force exerted by the compression spring on the first contact end, causing the second end of the elastic element to move upward and switch to touch the second contact end. Through the preset wiring of the detection board and the display circuit board, the second connection end and the third connection end are connected, thereby outputting that the current gas pressure has reached the pressure set value, and the second display light is used to intuitively illuminate and display the result.

[0043] The first, second, and third connection terminals can be connected to devices such as shutdown devices.

[0044] It is worth mentioning that the gas and other technical features involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0045] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
