Abstract

The invention discloses a novel light and simple epidemic situation protective mask which comprises a shell, a breathing part, a rotating mechanism, an elastic hoop, a respirator part, an elastic rubber strip, a strip-shaped framework and a sealing strip. The first semicircular protrusion of the elastic rubber strip is connected with the first semicircular groove of the protective edge in a clamped mode, the trapezoid section of the sealing strip is connected with the trapezoid groove of the strip-shaped framework in a clamped mode, and the attaching concave face of the sealing strip is attached to the face. According to the anti-epidemic mask, the protective mask can be more attached to the mouth and the nose during movement, the anti-fog effect is improved, normal use of the anti-epidemic mask is guaranteed, replacement is convenient, the mask is effectively prevented from falling off through the elastic hoop arranged on the head, and the using effect of the mask is improved.

Description

technical field [0001] The invention relates to the technical field of medical protection, in particular to a novel light and simple epidemic protective mask. Background technique [0002] With the increase of human activities and the destruction of the balance of nature, the current public health incidents have the characteristics of suddenness, unknownness and danger. Protection is critical. Protection mainly includes physical protection, immune protection and drug protection, and for physical protection, masks, protective gear, protective clothing, etc. are also required to take further epidemic prevention measures. The existing protective masks are inconvenient to replace, difficult to wear, and cannot be adjusted flexibly. They are all disposable masks, which need to be recycled after use, and the cost is too high. Contents of the invention [0003] In view of this, the present invention provides a novel light and simple epidemic protective mask to solve the above t...
