Portable breathing air supply device capable of realizing self-adaptive adjustment

Abstract

The invention discloses a portable breathing air supply device capable of realizing self-adaptive adjustment. The portable breathing air supply device is characterized in that a lung type valve is mounted in an inner cavity of a first shell and divides the inner cavity into an oxygen inlet inner cavity, an oxygen outlet inner cavity and an oxygen transfer inner cavity which are independent of oneanother, the oxygen inlet inner cavity is used for being connected with an oxygen source, the oxygen outlet inner cavity communicates with an oxygen inlet in an air suction pipe connector, the oxygentransfer inner cavity communicates with a mixed gas outlet in the air suction pipe connector, a corrugated pipe flow adjusting mechanism is mounted in an inner cavity of a second shell, and an air inlet and an air outlet of the corrugated pipe flow adjusting mechanism communicate with outside air and an air inlet in the air suction pipe joint respectively. The portable breathing air supply devicehas the advantages of facilitating self-adaptive adjustment of oxygen and air flow, being high in integration level, small in size, light in weight and convenient to carry, is suitable for providing oxygen supply protection for plateau operators, and can be widely applied to oxygen demand places such as plateau and mountainous regions and oxygen scenes for teaching tests.

Description

technical field [0001] The invention relates to a breathing air supply device, in particular to a self-adaptive adjustable portable breathing air supply device. Background technique [0002] The breathing air supply device is used to provide oxygen or a mixed gas with high oxygen content for people who need to inhale oxygen. The traditional breathing air supply device generally has large volume, difficulty in self-adaptive adjustment of oxygen concentration, and inhalation resistance. Bigger problem. [0003] Specifically, on the one hand, the traditional breathing air supply device does not integrate the automatic oxygen supply structure and the automatic air supply structure well. Whether to inhale a certain amount of outside air, or connect the respirator (such as a breathing mask or inspiratory tube) directly with the outside air through a trachea, but the automatic adjustment of the air flow cannot be realized; on the other hand, the oxygen of the traditional breathing...

[0003] Specifically, on the one hand, the traditional breathing air supply device does not integrate the automatic oxygen supply structure and the automatic air supply structure well. Whether to inhale a certain amount of outside air, or connect the respirator (such as a breathing mask or inspiratory tube) directly with the outside air through a trachea, but the automatic adjustment of the air flow cannot be realized; on the other hand, the oxygen of the traditional breathing air supply device The valve of the automatic air supply structure generally uses the axial elasticity of the spring, which results in a large suction resistance, and the air supply structure cannot realize the function of automatically adjusting the flow rate, let alone realize the self-adaptive adjustment of the air flow rate at different altitudes, so The oxygen concentration cannot be adjusted adaptively according to different environments such as different altitudes, which reduces the practicality of the product and the sense of user experience
