Integrated inflator

Abstract

The invention provides an integrated inflation device, which includes a gas cylinder assembly, a rotary valve assembly and a pressure reducing valve assembly; the gas cylinder assembly includes a gas cylinder body, a valve seat connected to the gas cylinder body, and a valve seat for accommodating the rotary valve assembly And the valve hole for its rotation forms a connected air passage between the valve hole and the relative rotating surface of the rotary valve assembly. The two side walls of the valve hole are correspondingly provided with air holes, one of which is the outlet of the gas cylinder body, and the other The air hole on one side is used to communicate with the air passage of the pressure relief valve assembly; the rotary valve assembly is provided with a sealing part; the pressure relief valve assembly includes a valve body, and an axially moving valve core is arranged inside it One end of the core is provided with a sealing gasket, and the sealing part and the sealing gasket can be used to open and close the air holes on both sides respectively, so as to realize quick on-off and voltage stabilizing functions. The invention can start to cut off or connect the gas path according to the inflation pressure, maintain the pressure stability, and has convenient operation and high reliability.

Description

technical field [0001] The invention relates to the technical field of inflators, in particular to an integrated inflator. Background technique [0002] The medical hemostatic airbags currently being developed at home and abroad need to be inflated by an inflator. At present, most of the manual inflatable inflators are inflated by manually squeezing the balloon, which is inconvenient to use and the inflation speed is slow. Although the electric air pump can achieve a faster inflation function, the electronic air pump has a large volume and is inconvenient to carry. [0003] Moreover, the general inflatable device cannot be automatically switched on and off following the air pressure of the inflated device, and the pressure is uncontrollable, which limits the application of the hemostatic air bag and the inflatable device. [0004] Therefore need to develop a kind of fast inflation and the inflation device of steady pressure. Contents of the invention [0005] Aiming at t...
