Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Example 1

The embodiment provides a double-deck gauze mask is breathed to gill of fish formula, including gauze mask body 1 and wearing rope 2. The wearing rope 2 can be elastic rope which can be hung behind ears, and is preferably non-elastic rope which can be bound behind the brain.

The mask body 1 comprises an outer layer mask, an inner layer mask and a breathing and filtering module 3.

The outer layer face mask and the inner layer face mask are made of impermeable materials, preferably flexible plastic materials. The edges of the outer layer face mask and the inner layer face mask are connected into a whole in a hot melting and sealing mode, and an interlayer space is reserved between the outer layer face mask and the inner layer face mask. Be provided with on the outer layer face cover and add mouth 4, in order to add the material and the material can not be excessive in can to the intermediate layer space, so add mouth 4 and must include the end cap of the joint of a stereoplasm and looks adaptation, can be threaded connection between joint and the end cap, the end cap also can adopt the plug, but specific scheme is that can conventionally choose for use among the prior art. The interlayer space can be filled with cooling media such as water, ice sand, cooling gel and the like, and can also be added with heat preservation media such as hot water, hot air and the like. The two different mediums are respectively suitable for two service environments in summer and winter. And the replacement of the medium is very simple and convenient.

Be provided with joint strip 5 at the edge of inlayer face guard for improve gauze mask body 1 and facial leakproofness, and because 5 width and the shape of joint strip that can reasonable in design, so can improve the comfort level of wearing.

And the inner layer mask is also provided with an isolation rubber strip 6 for separating the mouth and nose areas. The isolation adhesive tape 6 is designed according to the facial profile, and the face profile is attached to the back of the wearer, so that the breathing space of the mouth and the nose is distinguished, and an independent breathing space is formed.

The connection mode of the sealing rubber strip 5 and the isolation rubber strip can be selected by welding, bonding and the like.

The respiratory filtration module 3 comprises a respiratory passage 34, a filter body 33 and a first end cap 31.

The breathing passage 34 is a tubular structure supported by rigid plastic, and one end of the breathing passage is connected with the outer face mask in a welding way, and the other end of the breathing passage is connected with the inner face mask in a welding way. The filter 33 is at least one layer of meltblown fabric. The first end cap 31 compresses the filter body 33 against the end of the breathing passage 34 that connects to the outer face mask. The first end cap 31 is detachably connected to the breathing passage 34, and the specific connection means is optional in the prior art. However, the first end cap 31 is provided with an escape opening for exposing the filter 33, and in this embodiment, the first end cap 31 is specifically a hollow structure body in a window frame shape.

Two respiratory filter modules 3 are provided. For one, the end of the breathing passage 34 connected to the inner mask is located at a position corresponding to the nose; the end of the breathing passage 34 that connects to the outer mask is located in a position corresponding to the cheek. Thus forming the structural style of gill type breathing of the fish. On one hand, the design prolongs the circulation path of the sucked air flow, so that the air flow and the medium in the interlayer space exchange heat more fully; and on the other hand, the shapes of the outer layer face mask and the inner layer face mask can be supported to a certain extent.

And the other respiratory filtration module 3 is arranged below the isolation rubber strip and is used for oral respiration.

In conclusion, the technical scheme provided by the embodiment can conveniently add liquid or gas media or fine solid media, and can select media with different temperatures according to the specific conditions of outdoor temperature, thereby achieving better effects on cooling in summer and warming in winter. Compared with a mask completely made of melt-blown cloth, the mask is effective in that the mask is not breathable at any position, but the area of the breathing passage 34 is reduced, namely the size of the filter body 33 is limited, so that the mask has a better isolation effect. In addition, the filter 33 is replaceable, and compared with a mask made of melt-blown cloth completely, the material of the filter 33 is more fully utilized, and the waste of the melt-blown cloth is reduced.
