An anti-haze mask capable of supplying air actively through simple manual control of an air bag

Abstract

The invention provides an anti-haze mask capable of supplying air actively through simple manual control of an air bag. Firstly, when a hand squeezing air bag is extruded unceasingly with a hand, air enters an air transmission hose via a one-way air inlet valve; then the air is filtered and purified by a purifying device by the action of the high pressure of the hand squeezing air bag and enters a mask body via a purified air inlet for air supply. The mask is based on the principle of air flow of hydromechanics; air can be supplied actively by pressing and controlling the air bag connected with the one-way air inlet valve with a hand; air is filtered and purified via the purifying device by the action of high pressure of the air bag and then enters the air inlet of the mask via the air transmission channel, and thus purified air can be supplied to the inside of the mask continuously. The mask is simple in structure, low in cost, high in air purifying efficiency and long in using cycle, can be assembled and disassembled freely, and enables people to breathe easily and comfortably and exercise hand muscles; the air filtering and purifying device can be replaced conveniently.

Description

technical field [0001] The present invention relates to a simple and efficient anti-fog mask device that manually controls the air bag to actively supply air, in particular to actively controlling the air bag to absorb air, and the air passes through a replaceable air filter and purification device under high pressure to continuously provide purified gas for the inside of the mask . Background technique [0002] At present, the basic structure of known anti-fog masks is that the outer layer is an antibacterial fabric, the middle layer is a warm filler, and the bottom layer is a PM2.5 filter. According to the principle of gas flow in fluid mechanics, it is necessary to have a certain gas pressure difference inside and outside the mask to allow air to pass through the filter and exert the filtering effect. Ordinary anti-haze masks rely solely on the pressure difference generated by a single breath of the human body to make the air pass through the filter, and the air will be ...

AI Technical Summary

Problems solved by technology

Ordinary anti-haze masks rely solely on the pressure difference generated by a single breath of the human body to make the air pass through the filter.

At the same time, during the use of ordinary anti-haze masks, the exhaust gas exhaled by the human body cannot be discharged from the inside of the mask in time, resulting in problems such as repeated breathing of exhaust gas and the condensation of exhaled water vapor inside the mask that cannot be discharged.

In addition, the filtering effect of the filter is not good, it is laborious to inhale air, and the service life is short, it cannot be reused, and it cannot be easily replaced
