Embodiment 1

[0042] Such as figure 2 with image 3 As shown, a dust-proof N95 mask with low filtering resistance and its manufacturing method, comprising a mask cloth body 1, a nose bridge soft frame 2, a through groove 3, a notch 4 and a female Velcro 5, and the interlayer inner wall of the mask cloth body 1 is installed With soft nose bridge 2;

[0043] Specifically, the mask cloth body 1 is composed of two layers of non-woven fabric wrapped with a layer of N95 grade melt-blown cloth 31, and an additional layer of absorbent cotton cloth 33 is added. If the mask cloth body 1 is placed in front of the mouth and nose, it can be used for filtering Inhale the air from the mouth and nose to prevent viruses, dust and other debris in the air from entering the lungs of the human body along the air, and then induce respiratory infectious diseases and other phenomena. The nose bridge soft frame 2 is composed of polyolefin polymer and galvanized filaments. A layer of polyolefin polymer material i...

Embodiment 2

[0047] Such as figure 1 , Figure 4 with Figure 5 As shown, the back of the mask cloth body 1 is equipped with two sets of connecting ropes 9 arranged side by side, and the two ends of the connecting ropes 9 respectively run through the inside of the two sets of through grooves 3 arranged up and down, and one end of the connecting rope 9 is equipped with an ear rope. 10. A rubber sheet 11 is installed on the front side of the ear rope 10 .

[0048] Specifically, the connecting rope 9 can be used to install the ear-hanging rope 10, and the two are the same whole, both of which are made of a drawstring with a certain elasticity, and the two form a circle, and the two groups arranged on the back of the mask cloth body 1 There are 3 through slots arranged up and down, and there is no fixed point of contact between the whole body and the mask cloth body 1, which can avoid disconnection between the drawstring of the mask and the mask. One end of the ear rope 10 can be removed fro...

Embodiment 3

[0052] Such as Figure 7 with Figure 9 As shown, the front of the mask cloth body 1 is provided with four groups of symmetrically arranged through grooves 3, the front of the mask cloth body 1 is provided with a notch 4, and the front of the notch 4 is equipped with a female Velcro 5, and the female Velcro 5 is surrounded by Outer side of notch 4.

[0053] Specifically, the setting of the through groove 3 can facilitate the connecting rope 9 to be passed on the mask cloth body 1, and the setting of the notch 4 can facilitate the user to wear the mask and when the frame body 18 is not blocked, the exhaled gas goes out from here Discharge, the outer surface of mother Velcro 5 is arranged with fine fluff fiber, and it can stick to each other with child Velcro 16, and then realizes the detachable installation of parts such as back mold plate 17, frame body 18.

Abstract

The invention discloses a dustproof N95 mask with small filtering resistance and a manufacturing method thereof. The dustproof N95 mask comprises a mask cloth body, a nose bridge soft frame, a through groove, a notch and a female hook-and-loop fastener, and the nose bridge soft frame is installed on the inner wall of an interlayer of the mask cloth body; inclined soft rods are installed at the two ends of the nose bridge soft frame, transverse soft rods are installed at one ends of the two sets of inclined soft rods, two sets of symmetrically-arranged sponge strips are installed on the inner wall of an interlayer of the mask cloth body, and the outer wall of one side of each sponge strip is attached to the outer wall of the corresponding inclined soft rod. Four groups of symmetrically arranged through grooves are formed in the front surface of the mask cloth body, a notch is formed in the front surface of the mask cloth body, and a female magic tape is mounted on the front surface of the notch. After being worn, the mask can intercept water vapor and prevent the water vapor from being breathed upwards from the nose bridge to glasses, the mask can adjust the length of the rope, so that the mask is more fit to wear, the frame body and other parts in the device are convenient to disassemble, and if a user feels that the water vapor in the mask is much, the exhaust fan can be started to exhaust air.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a dust-proof N95 mask with low filtering resistance and a manufacturing method thereof. Background technique [0002] A mask is a sanitary product, generally referring to a device worn on the nose and mouth to filter the air entering the nose and mouth. It has the functions of isolating viruses, protecting oneself and others, preventing smog inhalation and keeping warm. Interacting with multi-layer non-woven fabrics, it has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent or when working in dusty and other polluted environments, masks are essential supplies. [0003] The defective that existing mask exists is: [0004] 1. Comparative document CN212661140U discloses a kind of medical N95 respirator, "comprising a cover body, the outside of the cover body is equipped with a bridge of nose by the top, both sides of the cover...
