Active respirator for children

Abstract

The invention provides an active respirator for children which comprises a respirator main body, wherein the respirator main body is a housing respirator main body; the outer side of the housing respirator main body is convex; a concave cavity is formed on the inner side of the housing respirator main body; the housing respirator main body comprises a front cover, a middle cover, a rear cover and a sealing ring, which are connected in sequence through snap fasteners; the sealing ring is contacted with a face; air inlet holes are formed at the joint of the front cover and the middle cover; air outlet holes are formed in the upper part of the middle cover; a filter unit is arranged on the middle cover and corresponds to the front cover; a cavity structure is arranged between the middle cover and the rear cover; a fan is arranged on the rear cover and corresponds to the filter unit of the middle cover; and an air outlet non-return valve, a battery connected with the fan, a control circuit board and a starting switch are arranged at the upper part of the rear cover. The active respirator is used for protecting children, is suitable for children to use in a hazy environment or other polluted environments, has a good protection effect and strong active air-suction power, is simpler and more convenient to manufacture, disassemble, assemble and clean, ensures a short and smooth air inlet passage, and meanwhile can avoid stimulation to lungs caused by the reason that air enters the lungs in case of high wind pressure.

Description

technical field [0001] The invention relates to the technical field of protective masks, in particular to an active protective mask for children. Background technique [0002] At present, the number of smog days in cities is increasing, and the concentration of PM2.5 pollutants in the air remains high. Indoors, air purifiers have been widely used for filtering, and the demand for purifying products worn by people is gradually increasing. Existing personal smog protection is mainly realized through N95 grade masks, etc. There are several problems in the existing masks: due to the high filtration level of the existing masks, the corresponding air resistance is large, thereby increasing the breathing resistance, and the breathing is not smooth enough. Especially for those with weak respiratory function, such as the elderly, children and those with respiratory diseases, wearing a mask may cause breathing difficulties. Contents of the invention [0003] The purpose of the pres...
