Novel oxygen mask

Abstract

The invention relates to the field of oxygen masks, and discloses a novel oxygen mask which comprises a mask main body, an oxygen corrugated pipe, a microphone and a fixing assembly. An inspiratory through hole and an expiratory through hole are formed in the two sides of the mask main body, and an inspiratory valve is arranged on the inspiratory through hole; one end of an oxygen corrugated pipeis connected with an onboard oxygen system, and the other end of the oxygen corrugated pipe is connected with the mask main body through the inspiratory valve; an expiratory valve is arranged on the expiratory through hole; and the mask main body is fixed to a human face through the fixing assembly. According to the novel oxygen mask, through design of an L-shaped stainless steel conductive bracket, an electric signal can be transmitted through the microphone without punching, so that the sealing performance of the telephone transmitter is improved. In addition, the weight of the mask is reduced, and the mask is light in overall weight, small in respiratory resistance, high in instantaneous flow, reasonable in hanging mechanism, high in overload resistance, and comfortable and convenient in wearing.

Description

technical field [0001] The invention relates to the field of oxygen supply masks, in particular to a novel oxygen supply mask. Background technique [0002] The main function of the oxygen supply mask is to separate the exhalation trachea from the surrounding atmosphere, so that the gas output by the oxygen supply system can be introduced into the human respiratory organs, so as to maintain the proper oxygen concentration of the inhaled gas and prevent the harm of high-altitude hypoxia to the human body. With the development of the times and the advancement of science and technology, the existing structure and technology of oxygen supply masks can no longer meet the current needs. The existing communication microphone (microphone) is built into the mask cavity, and the shape characteristics of the microphone itself are generally used. Fix it with the screw, punch a hole on the mask or the oxygen delivery tube to send the microphone wire out, so that the overall sealing of th...

Problems solved by technology

With the development of the times and the advancement of science and technology, the existing structure and technology of oxygen supply masks can no longer meet the current needs. The existing communication microphone (microphone) is built into the mask cavity, and the shape characteristics of the microphone itself are generally used. Fix it with the screw, make a hole on the mask or oxygen tube to send the microphone wire out, so that the overall sealing of the oxygen supply mask is poor

In addition, the exhalation resistance of the existing exhalation valve is relatively large, pilots who wear masks for a long time are prone to respiratory fatigue, and the comfort of wearing oxygen masks is poor

The exhalation valve in the existing oxygen supply mask uses a pressurized pipeline to induce air to the lower cavity of the exhalation valve to form a counter pressure. Pipeline, these pressurization methods lead to a large weight of the entire mask, which will also affect the wearing comfort of the oxygen supply mask
