Technical Field

[0001] The present application relates to the technical field of gas cylinders, and in particular to a pressure regulator. Background Art

[0002] Air pressure regulation is used in many aspects of reality. Balls in life, instruments in experiments, and tires on foot all require balanced air pressure regulation, including the negative pressure regulation in the cups in traditional Chinese medicine cupping therapy. This problem has not been completely solved until now. During the operation of cupping therapy, due to problems such as cupping technology and the patient's sensory sensitivity, patients often feel that the cups are not comfortable enough, or the negative pressure is not enough, or the negative pressure is too large. In existing cups, only the negative pressure can be increased, and it is not possible to fine-tune the negative pressure to reduce it. Therefore, if this problem is encountered during the cupping process, the cupping operation is often repeated. Therefore, there is still a lack of a cup pressure regulator in clinical practice that is both convenient and can fine-tune the negative pressure in the cup in the positive and negative directions to improve the comfort of the patient.

It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0022] It should be understood that although the terms first, second, third, etc. may be used in the present application to describe various components, these components should not be limited to these terms. These terms are only used to distinguish components of the same type from each other.

[0023] like Figure 1 and Figure 2As shown, this example provides a pressure regulator that can be used to adjust the pressure in a container. This example container is explained by taking a gas tank 19 as an example. The pressure regulator may include: a first pressure rod 2, a second pressure rod 3, a first pressure barrel 4, a second pressure barrel 5, a first cavity 6, a second cavity 7, an adjusting container 8, a first deformable pressure bag 9, a second deformable pressure bag 10, a first movable piston 11, a connecting piece 12, a second movable piston 13, a first adjusting switch 14, a piston rod 15, an air cylinder 16, a second adjusting switch 17, and a vent 18. The selection pressing button 1 is used to press the upper end of the first pressure rod 2 or the second pressure rod 3, and the lower end of the first pressure rod 2 extends into the first pressure barrel 4 and can move up and down along the first pressure barrel 4, and the contact between the two is sealed; the lower end of the second pressure rod 3 extends into the second pressure barrel 5 and can move along the The second pressure barrel 5 moves up and down, and the contact point between the two is sealed; the first pressure barrel 4 is connected to the second deformable pressure bag 10 through the first cavity 6, and the second pressure barrel 5 is connected to the first deformable pressure bag 9 through the second cavity 7. The first deformable pressure bag 9, the first movable piston 11 and the second deformable pressure bag 10 are arranged in the regulating container 8 in sequence, the first movable piston 11 is fixedly connected to the piston rod 15 through the connecting piece 12, the second movable piston 13 is arranged in the air cylinder 16, and the piston rod 15 is fixedly connected to the second movable piston 13. The first regulating switch 14 is installed on the air cylinder 16 and is located at the rodless end of the air cylinder 16. The rodless end of the air cylinder 16 is connected to the gas tank 19 through the vent pipe 18, and the vent pipe 18 is connected with the second regulating switch 17.

[0024] When the gas tank 19 is attached to the skin 20 and the negative pressure therein is small, the second regulating switch 17 is adjusted to the air outlet mode, and the first regulating switch 14 is adjusted to the air outlet mode. The first pressure rod 2 is pressed to squeeze the liquid in the first pressure barrel 4 into the second deformable pressure bag 10, and at the same time, the first movable piston 11 is squeezed to rise. The first movable piston 11 drives the connecting piece 12 to rise, and then drives the piston rod 15 to rise to pump air. At this time, the first regulating switch 14 is closed. At the same time, due to the pressure, the first deformable pressure bag 9 becomes smaller, and the liquid is squeezed out through the second cavity 7. When the liquid enters the second pressure barrel 5, the second pressure rod 3 rises, completing the air pumping action in the gas cylinder 19. Then, the second pressure rod 3 is pressed down, and the liquid in the first deformable pressure bag 9 is filled, forcing the first movable piston 11 downward, while driving the connecting piece 12, and then driving the piston rod 15 downward. At this time, the outlet mode of the first regulating switch 14 is open, and the second regulating switch 17 is adjusted to the closed mode. At the same time, due to the conduction of liquid pressure, the first pressure rod 2 rises, completing the air pumping action in the gas cylinder 16, thus completing a complete air pumping action. Repeat this several times until the patient feels comfortable. When the negative pressure in the gas tank is large, the second regulating switch 17 is in the air intake mode, and the piston rod 15 is used to adjust the first regulating switch 14 to the air intake mode, and the operation is performed in the reverse manner as described above.

[0025] In this example, the selection pressing button 1 is used to press the upper end of the first pressure rod 2 or the second pressure rod 3 .

[0026] Specifically, the selection press button 1 includes a press plate and a pivot, and the press plate is rotatably connected to the bracket 15 through the pivot, and the first pressure bar 2 and the second pressure bar 3 are arranged in parallel on both sides of the selection press button 1, so that the upper end of the first pressure bar 2 or the second pressure bar 3 can be selectively pressed through the selection press button 1.

[0027] In order to prevent the selection pressing button 1 from rebounding immediately after selectively pressing the first pressure rod 2 or the second pressure rod 3 , a gear damping member may be provided between the pressing plate and the pivot.

[0028] In order to reduce the wear between the pressing plate and the upper ends of the first pressure bar 2 or the second pressure bar 3, the upper ends of the first pressure bar 2 and the second pressure bar 3 can be arc-shaped or hemispherical. Preferably, the upper ends of the first pressure bar 2 and the second pressure bar 3 are both equipped with pulleys.

[0029] In this embodiment, the first lumen 6 and the second lumen 7 are filled with air or liquid, preferably liquid.

[0030] In this example, the regulating container 8 is a strip-shaped cavity with a notch in the sidewall. One end of the connector 12 extends into the cavity and is fixedly connected to the first movable piston 11. The first movable piston 11 is larger than the notch, preventing it from falling out. The two ends of the first movable piston 11 respectively abut the first deformable pressure bladder 9 and the second deformable pressure bladder 10.

[0031] It should be noted that the container in the above example is described using a gas tank as an example. The container can also be used to fine-tune the pressure balance of other closed containers, such as an inflatable cervical adjustment pad; or placed in an automatic constant pressure pneumatic balancing device, such as a tire pressure balance or a pressure-sensitive experimental instrument.
