Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

as shown in fig. 1-4, the utility model provides a lower exhaust type non-woven fabric mask, including mask 1, mask 1 includes outer non-woven fabric 11, melt-blown fabric 12 and inner non-woven fabric 13, and the outer layer of melt-blown fabric 12 is stained with outer non-woven fabric 11, and the inner layer of outer non-woven fabric 11 is stained with inner non-woven fabric 13, and annular ear belt rope 3 has been symmetrically bonded at the both ends of mask 1, and the top of inner non-woven fabric 13 is fixed with bendable bridge of the nose strip 2, and the bottom both ends symmetry of bridge of the nose strip 2 are fixed with adhesive tape 4, and the centre gripping has sponge 5 between two adhesive tape 4;

the inner layer of the mask 1 is provided with an exhaust structure 6, the exhaust structure 6 comprises an air guide strip 61, an exhaust ring frame 62 and an exhaust ring 63, the exhaust ring frame 62 is adhered to the bottom of the inner layer non-woven fabric 13, the air guide strip 61 is fixed at the top of the exhaust ring frame 62, and the exhaust ring 63 used for exhausting is fixed on the exhaust ring frame 62.

It should be noted that:

1. the sponge 5 is covered and arranged on the lower layer of the nose bridge strip 2, and the sponge 5 is of an inverted U-shaped structure; the sponge 5 can adsorb exhaled fog, and on the other hand, the sponge 5 is the U type structure of inversion, and the gaseous conduction of exhaling can be obstructed by the separation of U type structure.

2. The air guide strip 61 is a rubber component, one end of the air guide strip 61 is fixed on the exhaust ring frame 62, and the outer wall of the air guide strip 61 is adhered to the inner layer non-woven fabric 13 on the inner wall of the mask 1; the end face of the face attached to the mask 1 is divided into independent sections by the air guide strips 61, and exhaled air is blocked by the sponge 5 and then circulates downwards along the air guide strips 61 to the exhaust ring frame 62 for emission.

In this embodiment, in order to solve the problem that exhaled gas is discharged by gauze mask 1 upper portion, sponge 5 and exhaust structure 6 of U type are set up respectively to inlayer non-woven fabrics 13 top and bottom at gauze mask 1, wherein, sponge 5 is the U type structure of inversion, the gas of exhalation receives the separation of U type structure, but the gaseous conduction of separation, exhaust structure 6's air guide strip 61 separates into independent interval with the terminal surface of the attached people's face of gauze mask 1, the gas of exhalation receives behind the separation of sponge 5, circulate to exhaust ring frame 62 through exhaust ring 63 along air guide strip 61 downwards, in the use, the no gas discharge in gauze mask 1 upper portion, prevent that glasses from being infected with the fog.

As shown in fig. 3, the front end and the rear end of the exhaust ring 63 are symmetrically provided with an exhaust hole 632 and an exhalation hole 631, the inner diameter of the exhaust hole 632 is smaller than the inner diameter of the exhalation hole 631, and a conical exhaust channel is connected between the exhalation hole 631 and the exhaust hole 632.

It should be noted that, since the inner diameter of the exhaust hole 632 is smaller than the inner diameter of the exhalation hole 631 and the channel connecting the two is tapered, the two can only perform one-way exhaust operation, thereby preventing the user from inhaling the outside air through the exhaust ring 63 and maintaining the cleanliness of the inhaled air when the mask 1 is used.

As shown in fig. 5, the bent end faces of the nose bridge strip 2 and the sponge 5 are attached to the face of the user.

In this embodiment, nose bridge strip 2 is buckled and is driven sponge 5 and buckle, and nose bridge strip 2 and sponge 5 after buckling carry out the shutoff to the gap of gauze mask 1 and the attached department of people's face.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
