Abstract

The invention provides a filtration type breathing mask. The filtration type breathing mask comprises a mask body and a filtration body. An air accommodating cavity suitable for covering the mouth and the nose is formed in the inner side of the mask body. An exhaust port is formed in the wall surface of the air accommodating cavity. A fan and a filtration element are arranged in the filtration body. The filtration element is arranged on an air inlet channel of the fan. A diving mechanism connected with the fan is arranged. An air pipe communicating with an air outlet channel of the fan is arranged. The air outlet end of the air pipe communicates with the air accommodating cavity of the mask body. According to the filtration type breathing mask, the mask body and the filtration body are arranged separately, so that the weight of the mask body is reduced, and the problem that the human comfort is affected due to the fact that the noise of the fan is too high is effectively solved. In addition, due to the fact that the air accommodating cavity of the filtration type breathing mask covers the mouth and the nose, the space around nostrils can be filled with purified air, and the problem that polluted air is inhaled due to the fact that a purified air outlet is not matched with the nostrils is solved.

Description

technical field [0001] The invention belongs to the field of air purification, and in particular relates to an active filtering breathing mask capable of filtering fine particles. Background technique [0002] Haze is a weather phenomenon, which refers to a large number of fine dry dust particles such as dust floating in the air evenly, making the air cloudy, blurring the vision and leading to deterioration of visibility. Long-term exposure to smog will have a serious impact on human health. Studies have shown that smog can cause huge damage to the human respiratory system and cardiovascular system, and even cause cancer. Therefore, when going out in smog , more and more people choose to use filter masks for protective measures. [0003] In the prior art, the Chinese patent document CN20357717U discloses a mask for preventing particulate matter, the mask includes a mask body and a mask filter box connected to each other; The breathing piece is connected to the cover body, ...
