Mask capable of automatically adjusting breathing

Abstract

The invention discloses a mask capable of automatically adjusting breathing. The mask comprises a mask body (1) and a head band (2), wherein an exhalation valve seat (11) is arranged on the upper part of the mask body (1), an exhalation valve sheet (3) is installed on the exhalation valve seat (11), and a magnet sheet (12) is arranged at the outer end of the exhalation valve sheet (3); a control circuit board (4) is installed on the upper part of the mask body (1); and an integrated Hall sensor composed of a Hall semiconductor component and an accessory circuit thereof is arranged on the upper part of the control circuit board (4), and the magnet sheet (12) moves with the expiration valve sheet (3) to be away from or close to the Hall semiconductor component. The mask capable of realizing automatic breathing and electric air supply, which is disclosed by the invention, has portability of a self-breathing filtering respirator, and comfort (effectively reducing inhalation resistance and exhalation resistance). After actual measurement, the exhalation resistance is 51Pa, the inhalation resistance is 95Pa, and the allowances are high compared with the inhalation resistance of not greater than 350Pa and the exhalation resistance of not greater than 250Pa, which are stipulated by the national standards.

Description

technical field [0001] The invention relates to the field of personal protective equipment, in particular to a comfortable-wearing self-adjusting breathing mask. Background technique [0002] At present, there are many types of self-priming masks on the market, but for half-mask respirators, the space inside the mask is small, and at the same time, due to the addition of a filter box, the exhalation and inhalation resistance of the mask is very large, which is harmful to personnel. Wearing physiological comfort brings great hidden dangers. There are also electric air-supply masks on the market, but the batteries of this type of mask are very large, which is inconvenient to carry around. In addition, this type of air-supply mask is continuous air supply, which is easy to cause damage to the mouth and nose of the wearer in severe cold winter. Uncomfortable to wear. Contents of the invention [0003] The present invention proposes an automatic adjustment breathing mask, whi...
