Air storage tank and its pressure relief device

Abstract

The invention discloses an air reservoir and a pressure relief device thereof. The air reservoir comprises a reservoir body, an input unit, an output unit and the pressure relief device; the pressure relief device is provided with an outer cylinder, an inner column, an airtight element, a plug and a spring; a small-diameter hole, a large-diameter hole, a step wall located between the small-diameter hole and the large-diameter hole and a slotted hole communicating with the large-diameter hole are formed in the outer cylinder; the inner column is provided with a small column part, a large column part and a step part located between the small column part and the large column part; the small column part is located in the small-diameter hole; the large column part is located in the large-diameter hole; the inner column can reciprocate from a pressure sealing position to a pressure relief position; the airtight element is connected to the step part in a supporting way; the plug is connected to the large-diameter hole in a plugging way; the spring is connected between the large column part and the plug in a supporting way; when the inner column is located on the pressure sealing position, the airtight element is connected between the step part and the step wall in a supporting way to prevent gases from outwards leaking; and when the inner column is located on the pressure relief position, the airtight element is separated from the step wall, and gases and water in the air reservoir can be drained through a drain hole.

Description

technical field [0001] The present invention is related to bicycle related equipment, and more specifically refers to an air storage tank and a pressure relief device thereof, which can automatically release pressure and manually release water. Background technique [0002] Generally, the air pump of a bicycle uses the force of the user's hand to carry out piston movement to inject gas into the tire of the bicycle, so the pressure of the gas that can be injected is limited. However, there is currently a tubeless bicycle tire that needs to be inflated quickly. Injecting gas at high pressure, if it is inflated with a general pump, it will be difficult to inflate. Therefore, there is currently an air storage tank that can store high-pressure gas, which can be used to inflate a tubeless bicycle tire, so as to achieve the effect of convenient use. [0003] Taiwan, China has an island-type climate, and the relative humidity in the atmosphere is relatively high. The air itself con...

Problems solved by technology

[0005] The purpose of the present invention is to improve the background technology. The known air tanks used to inflate bicycles have problems such as not being able to automatically release pressure and easily releasing too much gas when releasing pressure and water; and to provide an automatic pressure release. And the air storage tank and its pressure relief device that can avoid excessive gas leakage during the pressure relief or water relief process
