Gas conveyer

Abstract

The invention discloses a gas conveyer. The gas conveyer comprises a gas source and an open type gas distributor, wherein the gas source is connected with the open type gas distributor through a gas conveying pipeline; the open type gas distributor comprises an outer shell; an inner shell is arranged in the outer shell; a gap is formed between the outer shell and the inner shell. The gas conveyer can isolate conveyed gas from external gas in an open type space, a small environment for the conveyed gas is formed on a human face, and gas circulation is formed on the human face by gas, so that exhaled gas can be exhausted through a circulation channel; moreover, gas from the gas source can be dispersed in a relatively open type space, so that the phenomena of poor breath or dizziness and chest distress are avoided during use; the conveyer is not required to be in hermetic contact with the mouth and nose of a person, so that the gas conveyer has higher adaptability and better gas conveying effect and is convenient for language communication of a wearer compared with a respirator and an enclosed face mask.

Description

technical field [0001] The invention belongs to the fields of medical device technology, air pollution protection, and health and hygiene, and relates to a conveyor, in particular to a gas conveyor. Background technique [0002] The function of the portable gas conveyor is to deliver specific gas to the user's mouth and nose through the distributor to meet specific needs. At present, portable air purifiers or respirators for medical treatment / cosmetic use directly send specific gases to the sealed nose for people to breathe; or deliver specific gases in a large open space for people to breathe. people breathe. [0003] However, if the existing portable gas delivery device is to send specific gas to the sealed nose for people to breathe, due to different human bodies, the user's breathing volume is different, and the user's breathing suction is different under normal conditions, or Due to insufficient intake, it is easy for the user to have difficulty breathing, dizziness, ...

AI Technical Summary

Problems solved by technology

The lack of a distributor will cause the supplied gas to diffuse rapidly in the surrounding environment, reducing the use effect of the delivered gas, and it is not suitable for use outdoors; or it is equipped with a sealed mask, but although the mask can prevent the diffusion of the gas, the mask is easy to make people feel stuffy. Dizziness, etc., and make it difficult to communicate with others
