[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] The present invention provides an adjustable gas generator for gas production.

[0026] like Figure 1 As shown, it includes a body 1 and an adjustment knob 13 connected to the front surface of the body 1. The front surface of the body 1 is provided with a generator switch 11 and a display screen 12. This part belongs to the existing structure of the gas generator and will not be described here.

[0027] like Figure 2-4 As shown, the front surface of the body 1 is connected to a positioning mechanism 2, which includes an annular fixed disk 21 fixedly connected to the front surface of the body 1 and coaxial with the adjustment knob 13. The front surface of the annular fixed disk 21 is provided with an annular groove 211, in which a positioning disk 23 is slidably connected. The inner walls of both sides of the annular groove 211 are provided with annular inner grooves 212 that allow the edge of the positioning disk 23 to be engaged and slide. A connecting post 24 is fixedly connected to the front end of the connecting post 24, and a guide bar 25 is fixedly connected to the front end of the connecting post 24. A positioning stopper 26 is slidably connected to the guide bar 25. A guide ring 251 is fixedly connected to the guide bar 25, and the guide ring 251 is movably connected to the positioning stopper 26. The front end side of the adjusting knob 13 is fixedly connected to a positioning column 131, and one end of the positioning stop rod 26 extends out from the guide bar 25 to block the positioning column 131. The other end of the positioning stop rod 26 is fixedly connected to a shaft handle 261, and the lower surface of the shaft handle 261 fits with the upper surface of the guide bar 25. The shaft handle 261 is made of a rubber material with good friction performance, that is, there is a certain friction between the lower surface of the shaft handle 261 and the guide bar 25, which does not affect the movement of the positioning stop rod 26 and can limit the positioning stop rod 26 after movement.

[0028] like Figure 4-5 As shown, an arc-shaped guide piece 231 is fixedly connected to the bottom of the positioning plate 23 , and an annular guide groove 213 is formed on the bottom surface of the annular groove 211 to allow the arc-shaped guide piece 231 to slide horizontally.

[0029] like Figure 5As shown, the outer annular surface of the positioning disk 23 is fixedly connected to a limiting cylinder 27, which is sleeved with a limiting shaft 28. The bottom end of the limiting shaft 28 is fixedly connected to a limiting stop 281. A limiting spring 29 is disposed inside the limiting cylinder 27. The limiting spring 29 sleeves on the outside of the limiting shaft 28, with one end of the limiting spring 29 fixedly connected to the inner wall of the limiting cylinder 27 and the other end of the limiting spring 29 fixedly connected to the outer wall of the limiting shaft 28. The limiting spring 29 uses elastic thrust to force the limiting stop 281 into close contact with the annular groove 211, and the friction between the two achieves rapid positioning of the positioning disk 23.

[0030] like Figure 2 As shown, a scale plate 22 is fixedly sleeved on the outer ring surface of the front end of the annular fixed disk 21, and scale lines are set on the scale plate 22. The scale lines are used to more intuitively mark the position of each positioning mechanism 2, that is, to intuitively mark the gas production value corresponding to the positioning mechanism 2 at the corresponding position, so that the staff can quickly find the corresponding positioning mechanism 2 when producing a certain value of gas.

[0031] The working principle of the present embodiment is as follows: when producing gas, it is necessary to rotate the adjusting knob 13 to set the gas amount to be produced in advance. When rotating and adjusting the adjusting knob 13, the numerical value change is observed through the display screen 12. When the numerical value displayed on the display screen 12 equals the gas amount to be produced, the adjusting knob 13 is stopped from rotating. However, in actual use, the adjusting knob 13 cannot be accurately rotated to the correct position in one go, and it is necessary to repeatedly rotate and debug the adjustment knob, which undoubtedly causes inconvenience. In the present embodiment, some commonly used gas production amount numerical values ​​can be preset in advance, and when producing gas, the adjusting knob 13 can be directly rotated to the specified position corresponding to the numerical value in one step, without the need for repeated rotation and debugging.

[0032] Specifically, the sliding connection between the positioning lever 26 and the guide bar 25 allows the positioning lever 26 to be linearly moved and adjusted, so that it is located in the rotation path of the positioning post 131. When the adjustment knob 13 is rotated, the positioning post 131 is blocked by the positioning lever 26, causing the adjustment knob 13 to stop rotating. At this time, the position of the positioning lever 26 corresponds to the pre-set amount of gas to be produced. In other words, as long as the position of the positioning lever 26 is set in advance, the adjustment knob 13 can be rotated into place in one step each time.

[0033] The positioning plate 23 slides within the annular groove 211, allowing the positioning lever 26 to be rotated and adjusted in position, thereby adapting the positioning lever 26 to different gas values. In this embodiment, five positioning levers 26 are provided, corresponding to five commonly used gas production values. To produce a gas of a specific value, the single positioning lever 26 corresponding to that value is simply translated into the rotation path of the positioning post 131. In actual applications, other numbers of positioning levers 26 may be provided as needed.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
