Problems solved by technology

[0006] Therefore, breathing resistance and filtering performance are a pair of irreconcilable contradictions in existing masks, that is, if the breathing resistance is to be reduced, the filtering performance will be correspondingly reduced, and if the filtering capacity is to be improved, the filtering resistance will be correspondingly increased

Embodiment 1

[0067] Embodiment one, such as figure 1 As shown, the multifunctional various mouth masks of the present invention include filter layer, frenulum 5, and described filter layer is made up of outer filter layer 1, inner filter layer 2, and regulator 3 between two filter layers, and regulator 3 is A three-dimensional net used to increase the effective filtration area of ​​the filtration layer. The opening of the inner filter layer 2 is equipped with an annular guide ring 4 positioned at the periphery of the mouth and nostrils for making the peripheral edge close to the face. The filter layer adopts a structural form that gradually thickens from the edge to the suction center.

Embodiment 2

[0068] Embodiment two, such as figure 2 with 4 As shown, the multifunctional various mouth masks of the present invention comprise filter layer, frenulum 5, and described filter layer goes out outer filter layer 1, inner filter layer 2 and is positioned at the adjustment thing 3 composition between two filter layers, and adjustment thing 3 is A three-dimensional net used to increase the effective filtration area of ​​the filtration layer. The opening of the inner filter layer 2 is equipped with an annular guide ring 4 positioned at the periphery of the mouth and nostrils for making the peripheral edge close to the face. One-way non-return breathing valve 6 is housed on the outer filter layer 1 . The one-way non-return breathing valve 6 includes a valve wall 6-1 with a through hole and a bracket 6-2 installed on the valve wall 6-1. The bracket 6-2 is equipped with a push-pull rod 6-3, and the push-pull rod 6 The two ends of -3 are equipped with the leather valve plate 6-4 t...

Embodiment 3

[0069]Embodiment three, such as image 3 with 4 As shown, the multifunctional various mouth masks of the present invention include filter layer, frenulum 5, and described filter layer is made up of outer filter layer 1, inner filter layer 2, and regulator 3 between two filter layers, and regulator 3 is A three-dimensional net used to increase the effective filtration area of ​​the filtration layer. The opening of the inner filter layer 2 is equipped with a hemispherical shell-shaped guide ring 4 that is positioned at the mouth and nostril periphery and is used to make the outer peripheral edge stick to the face and provide the activity space for the mouth. The top of the guide ring 4 is equipped with a one-way non-return exhalation valve 6 leading to the outside. Suction valve 6. The one-way non-return breathing valve 6 more preferably includes a valve wall 6-1 with a through hole and a bracket 6-2 installed on the valve wall 6-1, the bracket 6-2 is equipped with a push-pul...

Abstract

The present invention relates to a forced respiration filtering method for gauze mask, and multiple functional mask using same method. In order to solve the problem that the existing gauze mask has big breathing resistance and weak filtering ability, the gauze mask includes filtering layer and chalaza, the filtering layer consists of lateral uniform filtering layer, medial uniform filtering layer and adjusting material between the two layers, the adjusting material is the transposable type three-dimensional net or transposable type stent to increase the efficient filtering acreage of the filtering layer; between the mount and the nostril periphery on the opening of the filtering layer, there is guiding cycle which is used to make the peripheral edge close the face or closed-end guiding cycle which is used to make the peripheral edge close the face and provide active spaces. Thus, this gauze mask possesses the advantage of simple structure, manufacture easily, use conveniently, large effect filtering area, strong filtering ability, small respiratory resistance, excellent anti-infect performance, wide application field, low cost, wide extension application prospect.

Description

technical field [0001] The invention relates to an air filtering technology for human respiration, in particular to a powerful breathing filtering method for a mask and a multifunctional mask using the method. Background technique [0002] In the past, ordinary masks are hereinafter referred to as "ordinary" masks, which use gauze as filter materials, hereinafter referred to as "soft" materials. N95 and other masks are convex masks, hereinafter referred to as "convex" masks, which use relatively hard materials such as activated carbon as the filter layer, hereinafter referred to as "hard" materials. [0003] What kind of filter material (material, structure, shape, density, thickness, adsorption capacity, etc.) is selected for the mask is an important factor in the filter performance of the mask. The pressure generated by the inhalation speed on the filter layer when wearing a mask is another important factor for the filtering effect. Then there is the problem of sealing p...
