Embodiment Construction

[0030] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0031] A protective mask is composed of a cover body, a one-way breathing valve 8, an oxygen diffuser tube 9 and a pair of oxygen generating devices.

[0032] The oxygen diffuser tube 9 is preferably an aluminum bar on the bridge of the nose in the existing cover, and the aluminum bar has a built-in upper lumen 10 and a lower lumen 11; The middle part of the tube is connected, and the oxygen diffuser hole 12 is arranged on the tube wall of the lower tube cavity 11 . The filter cotton is placed horizontally in the upper lumen 10 .

[0033] The one-way breathing valve 8 is arranged at the middle part of the inner side of the cover body, and the airway tube 13 is drawn out from both sides.

[0034] A pair of oxygen generating devices are respectively placed at the two ends outside the cover body. The main body of the oxygen generating dev...

Abstract

A protective mask comprises a mask body, a one-way breather valve, an oxygen generating device and an oxygen dispersing pipe. The oxygen production device is arranged on the outer side of the cover body and comprises an oxygen production pipe, and a pipe cavity is sequentially divided into a heat absorption cavity, an adsorption cavity 3, an oxygen production cavity and an air inlet cavity formed in the bottom of the pipe cavity in the pipe length direction, the air inlet cavity is connected with a one-way breather valve arranged in the middle of the inner side of the mask body through an air inlet formed in the pipe wall. An oxygen production material is arranged in the oxygen production cavity, an air purification material is arranged in the adsorption cavity 3, a heat absorption material is arranged in the heat absorption cavity, and oxygen produced by the oxygen production cavity sequentially passes through the adsorption cavity 3 and the heat absorption cavity and then is aerated through a free-ranging pipe which is arranged in the cover body and is communicated with an air outlet formed in the pipe wall. The principle that oxygen is generated by sodium peroxide, water and carbon dioxide is utilized, main components of expired air of the human body are water and carbon dioxide, and oxygen for the human body to inhale is produced; the reaction heat is utilized to thermally dry the flowers to generate fragrance, so that the oppressed feeling of wearing the mask is relieved, the mood is pleasant, and the mask has very high practicability and wide applicability.

Description

technical field [0001] The invention relates to a protective mask, in particular to a protective mask and a using method thereof. Background technique [0002] The existing N95 protective mask has a four-layer structure: including non-woven fabrics on both sides, melt-blown fabric and hot-air cotton in the middle, which has a certain thickness, thermal insulation, moisture-proof and moisture-proof properties, and improves the comfort of the wearer. However, due to the existence of hot air cotton, the thickness of the mask is increased, which makes the protective mask unfavorable for medical staff to wear for a long time, and it is easy to produce a feeling of suffocation, and even a certain sense of hypoxia. Therefore, need a kind of protective mask that can effectively alleviate this phenomenon. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a protective mask and its use method tha...
