Example 1:
the negative pressure control valve of the sputum suction tube with adjustable negative pressure as shown in the figures 1-3 can rapidly control the negative pressure of the sputum suction tube, adapt to different patients and timely adjust the negative pressure according to the conditions of the patients.
A negative pressure adjustable sputum aspirator negative pressure control valve, comprising: the body 1, button 2, connecting pipe 3, negative pressure adjustment mechanism 4, button 2 rotates with body 1 through the pivot in body 1 top and is connected, and negative pressure adjustment mechanism 4 is inside body 1, and connecting pipe 3 runs through to body 1 inside and is connected with negative pressure adjustment mechanism 4, button 2 and negative pressure adjustment mechanism 4 contact.
The negative pressure regulating mechanism 4 comprises a valve seat 41, a valve rod 42, a connecting rod mechanism 43, a first spring 44 and a spring upright 45, wherein the valve seat 41 is arranged in the body 1, the spring upright 45 is arranged at the bottom of the valve seat 41, the first spring 44 is sleeved on the spring upright 45, the valve rod 42 is sleeved above the first spring 44, and the connecting rod mechanism 43 is arranged above the valve rod 42. The negative pressure adjusting mechanism 4 is used for adjusting the negative pressure.
The valve seat 41 is communicated with the connecting pipe 3, and the valve rod 42 is provided with 4 negative pressure channels 421 with different diameters, and the negative pressure channels 421 are uniformly arranged on the valve rod 42 in the vertical direction. The diameter of the connecting pipe 3 is 16mm, and the diameters of the negative pressure channels 421 are 16mm,12mm,10mm and 8mm respectively, and the negative pressure size can be adjusted by adjusting the diameters of the negative pressure channels 421 through different negative pressure channels 421.
The valve seat 41 is internally provided with a slide 411, the slide 411 is internally provided with 4 grooves 412, the grooves 412 are in one-to-one correspondence with the negative pressure channels 421, and the distance from each groove 412 to the connecting pipe 3 is the same as the distance from the corresponding negative pressure channel 421 to the connecting rod mechanism 43. Above the valve stem 42 there is a chute 422 and the linkage 43 is within the chute 422. The link mechanism 43 comprises a cross rod 431, a connecting rod 432 and a vertical rod 433, wherein the cross rod 431 is arranged in the chute 422, one end of the connecting rod 432 is connected with the cross rod 431, and the other end is connected with the vertical rod 433. The two cross bars 431 and the two connecting bars 432 are symmetrically distributed on two sides of the vertical bar 433, and one end of the cross bar 431 outside is arranged in the slide 411. A second spring 434 is connected between the crossbars 431. When the button 2 presses the link mechanism 43, the link mechanism 43 converts the force received by the vertical rod 433 into the outward force received by the cross rod 431, so that the cross rod 431 slides in the slide 411 and is blocked with the groove 412 at the position where the cross rod 431 slides into the groove 412 in the slide 411, and the blocked position just can enable the negative pressure channel 421 to be aligned with the connecting pipe 3.

The lower part of the button 2 is provided with a lug 21, the bottom of the lug 21 is arc-shaped, and the bottom end of the lug 21 is contacted with the upper end of the vertical rod 433. The bottom of the convex block 21 of the button 2 is arc-shaped, and the button 2 is smoother when contacting with the vertical rod 433.
Working principle: when the button 2 is pressed, the bump 21 presses the link mechanism 43, the vertical rod 433 converts the vertical force into an outward force applied to the cross rod 431, and the cross rod 431 is pushed outward against the slide 411. The vertical force increases and the linkage 43 imparts a force to the valve stem 42, which valve stem 42 moves downward compressing the first spring 44. The cross bar 431 slides on the slideway 411, and when the cross bar 431 slides to the groove 412, the cross bar 431 is blocked with the groove 412, and the negative pressure channel 421 is aligned with the connecting pipe 3.
When the negative pressure replacement negative pressure channel 421 needs to be adjusted, the button 2 is continuously pressed, and the cross rod 431 continuously slides to be blocked with the next groove 412, so that the negative pressure channel 421 is replaced.
After sputum aspiration is finished, the button 2 is loosened, the vertical rod 433 loses vertical pressure, the horizontal rod 431 is pulled inwards by the pulling force of the second spring 434, the horizontal rod 431 and the groove 412 are clamped, and the valve rod 42 is quickly sprung up by the first spring 44, so that the quick closing effect is realized.
