Description

Technical Field

[0001] The utility model belongs to the technical field of air pressure devices, and in particular relates to an adjustable air pressure device. Background Art

[0002] Pneumatic devices usually refer to systems that use air pressure differences to achieve force transmission and control. They involve the compression, delivery, control and application of gas. The working principle of pneumatic devices is based on the compressibility and volatility of gas. The air pressure generator compresses air into high-pressure gas through a compressor, and then transmits it through a pipeline to where force is needed. Pneumatic devices have various functions and can be used for simple pressure control as well as complex automated control systems.

[0003] When the air pressure device is used to transport water inside the bottle, the opening of the bottle is sealed, and then the transport pipe is connected, and the pressure inside the bottle is controlled by the air pressure device, so that the water inside the bottle can be controlled to flow in or out.

[0004] In the prior art, a positive air pressure pump or a negative air pressure pump is usually used to pressurize or depressurize a sealed bottle body, so as to achieve the effect of making the water inside the bottle body flow out or flow in. However, during use, the air pump usually rotates at a high speed in order to achieve the effect of changing the air pressure inside the bottle body, so that the air pressure inside the bottle body changes faster, thereby making the water flow speed inside the bottle body faster. It is not easy to control the water flow speed according to demand, which can easily cause waste of resources and is not conducive to the subsequent work.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an adjustable air pressure device.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
