Embodiment Construction

[0013] Below in conjunction with accompanying drawing 2, the present invention is described in detail. The device bracket (103) adopts an integrated design, and is divided into two chambers in the middle: the air-clearing chamber (109) and the exchange chamber (105). spliced ​​into a whole under the premise of sex. The air cleaning chamber (109) is communicated with the exchange chamber (105) through a one-way valve (104), and the gas can only enter the exchange chamber side from one side of the air cleaning chamber through the one-way valve (104). A one-way valve (106) is also installed on the exchange cavity, so that the gas can only flow out from the exchange cavity, but not flow in.

[0014] In this embodiment, the support part of the air-cleaning cavity is a cylindrical structure, and as an option, this part of the support may also be in the form of a rectangle, a sphere, or the like. Many air inlet holes (102) are opened on the side of the bracket, so that the bracket ...

Abstract

Aiming at the problems, the invention provides a dual-chamber structure design. The dual-chamber structure design is suitable for a mask, a breathing mask and the like; the gas exchange efficiency is improved, and the asphyxia sensation during breathing is reduced while filtering purification of air can be realized; during inspiration, a one-way valve (7) is opened, a one-way valve (9) is closed, and gas as in a fresh air cavity (3) enters an exchange cavity (8) through the one-way valve (7) and further enters a respiratory system of a person; during expiration, the one-way valve (7) is closed, the one-way valve (9) is opened, and expired gas is quickly exhausted from the exchange cavity without reservation; in the expiring process, the one-way valve (7) is closed, and outside air continuously enters the fresh air cavity through a filter screen (1) by negative pressure generated in the fresh air cavity in the inspiration process; and clear air is supplemented and prepares for next inspiration, and the steps are repeated as above.

Description

technical field [0001] The invention relates to a gas filtration and exchange device with a double-chamber structure, which is suitable for the occasions of filtering and exchanging gas, such as masks, gas masks and other devices, and solves the problem of poor gas exchange performance and strong suffocation during the exchange process. question. Background technique [0002] The rapid development of society has also brought some environmental problems, such as air pollution. While people are more and more aware of the harm that air pollution brings to people's health, there are few means to overcome it. At present, when people travel in severe weather such as smog, they generally take protective measures such as wearing masks. There are many similar products on the market, and the principle is generally similar, that is, when inhaling, the dirty air passes through the filter layer of the mask to filter out harmful substances, such as PM2.5. However, due to the very small...
