[0023] The following describes the specific implementation of the present invention in detail with reference to the accompanying drawings.

[0024] Example:

[0025] The following figures show a specific embodiment of the air regulating valve of the present invention. Figure 1 、 Figure 2 It mainly includes a valve body 1, a check valve assembly 2, a pneumatic disc assembly 3, and an air intake adjustment assembly 4. The pneumatic disc assembly 3 and the check valve assembly 2 are installed up and down in the valve body 1, and the air intake adjustment assembly 4 is installed on the top of the valve body 1.

[0026] Reference Figure 2 、 Figure 6 The specific structure of the valve body 1 is that the interior of the valve body 1 is hollow and the top is open. A feed port 101 is provided on one side of the valve body 1, and a discharge port 102 is provided at the bottom of the valve body 1. The feed port 101 and the discharge port 102 are both connected to the interior of the valve body 1.

[0027] Reference Figure 3 、 Figure 6 The specific structure of the check valve assembly 2 is as follows: the check valve assembly 2 includes a check valve body 201, within which a lower ejector pin 202 is mounted. The lower ejector pin 202 extends through the bottom end of the check valve body 201 and extends to the outside. A second spring 203 is interposed between the lower ejector pin 202 and the check valve body 201. The inner wall of the check valve body 201 is provided with an inwardly protruding first step 201b. The two ends of the second spring 203 respectively abut against the needle head 202a of the lower ejector pin 202 and the first step 201b. The bottom end of the lower ejector pin 202 is connected to a limit nut 204. The lower ejector pin 202 is extended and retracted upward and downward by the second spring 203. The limit nut 204 is used to limit the position of the lower ejector pin 202 within the check valve body 201.

[0028] A plurality of through holes 201a are provided on the side wall of the check valve body 201. When the lower ejector pin 202 moves downward, the limit nut 204 is driven to move downward synchronously, the second spring 203 is compressed, and the through hole 201a is connected to the interior of the check valve body 201. The air inside the check valve body 201 can flow through the through hole 201a to the outside of the check valve body 201.

[0029] When the check valve assembly 2 is installed in the valve body 1, a second step 103 protruding inward is provided on the inner wall of the valve body 1. The check valve assembly 2 is downwardly inserted into the valve body 1, and the check valve body 201 is installed on the second step 103. There is a gap between the check valve body 201 and the second step 103 for material flow.

[0030] Reference Figure 4 、 Figure 6 The pneumatic disc assembly 3 specifically comprises a pneumatic disc body 301, which is mounted above the check valve assembly 2 and divides the interior of the valve body 1 into two sections. A vent hole 301a extending vertically through the pneumatic disc body 301 is formed. The lower ejector pin 202 of the check valve assembly 2 is pressed against the bottom of the vent hole 301a. Specifically, the lower ejector pin 202 penetrates the bottom of the vent hole 301a and abuts against the wall of the vent hole 301a. A sealing ring 302 is provided on the outside of the pneumatic disc body 301, which tightly abuts against the inner wall of the valve body 1.

[0031] Reference Figure 5 The specific structure of the air intake adjustment component 4 is that the air intake adjustment component 4 includes an adjustment knob 401, and the outer surface of the adjustment knob 401 is provided with a scale. An adjustment nut 402 is provided inside the adjustment knob 401, and the adjustment knob 401 and the adjustment nut 402 are fixedly connected by a set screw 405. The adjustment nut 402 is threadedly connected to the top of the valve body 1 ( Figure 5 The threads on the middle adjusting nut 402 are not shown. Figure 1 (The threads on the middle valve body 1 are not shown.) An adjusting pin 403 is connected to the adjusting nut 402. This pin 403 includes a pin mounting block 403a, which is provided with an air inlet 403b extending vertically therethrough. An upper pin 403c is located at the bottom of the pin mounting block 403a. Upper pin 403c abuts against the top of the air vent 301a. Specifically, upper pin 403c penetrates the top of the air vent 301a and abuts against the wall of the air vent 301a. A first spring 404 is also located within the adjusting nut 402, the lower end of which abuts against the pneumatic disc body 301.

[0032] When the air regulating valve of the present invention is working, the discharge port 102 at the bottom of the valve body 1 will be subjected to negative pressure suction. By rotating the adjusting knob 401, under the action of the first spring 404, the upper ejector pin 403c and the air vent 301a on the pneumatic disk body 301 will slowly separate, and the air can be sucked into the upper part of the pneumatic disk body 301 through the air inlet hole 403b at the top of the air inlet regulating component 4. By controlling the rotation angle of the adjusting knob 401, the lifting height of the upper ejector pin 403c can be controlled, thereby adjusting the amount of air entering. The lower ejector pin 202 in the check valve assembly 2 is affected by the negative pressure, causing it to move downward. This in turn drives the retaining nut 204 at its bottom end downward, separating the lower ejector pin 202 from the air vent 301a in the pneumatic disc body 301. Air flows downward through the air vent 301a, through the pneumatic disc body 301, and into the check valve body 201. Simultaneously, the downward movement of the lower ejector pin 202 compresses the second spring 203, connecting the through-hole 201a in the check valve body 201 with the interior of the check valve body 201. Air inside the check valve body 201 can then pass through the through-hole 201a and into the valve body 1. Cream is drawn into the valve body 1 through the feed port 101 on the side of the valve body 1. After mixing with the incoming air, cream flows downward through the gap between the check valve body 201 and the second step 103 inside the valve body 1, ultimately being discharged through the discharge port 102 at the bottom of the valve body 1. When the air regulating valve is not working, the negative pressure suction at the outlet 102 at the bottom of the valve body 1 disappears, the check valve assembly 2 is reset, the lower ejector pin 202 is pressed tightly against the pneumatic disc body 301, the adjusting knob 401 is in a tightened state, the first spring 404 is compressed, the upper ejector pin 403c is pressed tightly against the pneumatic disc body 301, and air cannot enter.

[0033] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included within the scope of protection of the present invention.
