Embodiment Construction

[0032] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0033] Such as figure 1 As shown, the mask according to the embodiment of the present invention includes a cover body 1, the cover body 1 has an upper edge and a lower edge, and the upper edge is provided with a length adjustment member 2 and an adaptive member 3, and the adaptive member 3 is located on the length adjustment member. 2, the length adjustment component can bend with the facial curve and act on the adaptive component, so that the adaptive component is deformed by force and adapts to the facial curve to fit on the face. The self-adaptive component should fit inward with the facial structure to realize the sealing of the upper edge of the mask.

Abstract

The invention discloses a mask. The mask comprises a mask body, the upper edge of the mask body is provided with a length adjusting component and a self-adaptive component, the self-adaptive componentis arranged on the inner side of the length adjusting component, and the length adjusting component can be bent along with the curve of the face and acts on the self-adaptive component to make the self-adaptive component stressed to deform and adapted to the face curve to be attached to the face. According to the mask provided by the embodiment of the invention, the shape of the upper edge of themask body can be self-adaptively adjusted according to the face shape of a user, the mask is more tightly attached to the face, and the protection effect of the mask is effectively improved.

Description

technical field [0001] The invention relates to the field of medical and health technologies, in particular to a mask. Background technique [0002] Mask is a kind of sanitary protective equipment, which is used to reduce or prevent harmful particles in the air, including germs, viruses, suspended particles, harmful gases, etc. , Health field. Especially in some highly polluted environments, masks have become an essential protective tool. [0003] In order to ensure that the mask has a good protective effect, it is necessary that the mask and the face fit well, otherwise harmful gases can easily enter the internal breathing space from the gap between the mask and the face, especially from both sides of the bridge of the nose. In the related art, a recess or a bead is provided at the position corresponding to the bridge of the nose of the mask, but the fit between the mask and the bridge of the nose is poor for the form of the recess; for the form of the bead, the bead is p...
