Abstract

The invention relates to an active blowing filtering device for a protecting head cover. The device comprises a blowing filtering module (1), an electric control unit (2) and a structural shell (3), wherein the blowing filtering module (1) and the electric control unit (2) are mounted in the structural shell (3); the blowing filtering module (1) is electrically connected to the electric control unit (2). The device is characterized in that the blowing filtering module (1) comprises an efficient filter screen (4), a centrifugal fan (5), a blowing pipeline (6) and a fast plug (7). The efficientfilter screen (4) and the centrifugal fan (5) are fixedly mounted in the structural shell (3); the efficient filter screen (4), the centrifugal fan (5) and the blowing pipeline (6) are arranged successively to form an active blowing cavity. The fast plug (7) connects an air outlet of the centrifugal fan (5) to the blowing pipeline (6) hermetically. The active blowing filtering device overcome a defect that an existing protecting head cover cannot provide high quality air continuously, and guarantees breathing safety of staff in a special environment.

Description

technical field [0001] The invention relates to an active air supply filter device, in particular to an active air supply filter device for a protective hood. Background technique [0002] Protective headgear can effectively prevent dust, bacteria, droplets and other harmful particles in the ambient air from directly contacting the wearer. It is widely used in medical and health care, labor protection, and experimental research. With the development of technology in the field of air purification, traditional hoods with a single protective function can no longer meet people's requirements for equipment comfort, and the discomfort caused by wearing protective hoods such as hypoxia, chest tightness, and eyepiece fogging more and more prominent. Therefore, there is a need for an active air supply filter device for a protective hood, which, under the action of a fan, filters ambient air and sends it into the interior of the protective hood to improve wearing comfort.
