Abstract

The invention relates to the field of personal protection equipment and provides a sealing support component used for an anti-haze face mask. The sealing support component comprises a support piece and a seal ring. The support piece is of a sheet structure made of a rigid material and provided with a plurality of gas flow channels allowing gas to flow through. The seal ring is made of an elastic material and wraps the edge of the sealing support component. The invention further provides the anti-haze face mask provided with the sealing support component. The sealing support component providedby the invention can have a fixing and supporting effect on a filter element, and accordingly, the filter element in the anti-haze face mask is not prone to deforming; and in addition, a one-way valveis arranged on the sealing support component, the one-way valve does not need to be dismounted in the replacing process of the filter element, and therefore, the steps of mounting and dismounting ofthe filter element are simplified.

Description

technical field [0001] The invention relates to the field of personal protection devices, in particular to a sealing support for an anti-haze mask and an anti-haze mask. Background technique [0002] With the increasingly serious environmental pollution and smog, anti-smog masks are welcomed by more and more consumers. The anti-smog masks mainly filter the air through the filter element layer. The filter elements in the prior art are usually formed by hot-melting or pressing multi-layer filter materials. Due to the flexibility of the filter materials, the filter elements are often easily deformed, which makes it usually necessary to use an additional pressure plate structure on the anti-haze mask to adjust the filter element. The structure of the anti-haze mask is fixed and supported; in addition, a one-way valve that can discharge air toward the outside of the anti-haze mask is usually set on the filter element of the prior art, so as to avoid the situation that the exhaled...
