Abstract

The utility model discloses a gas-filtering protective oral-nasal mask which comprises a spray-bonded cotton layer and fiber cloth layers on the side surfaces of the spray bonded cotton layer, the peripheries of which are fixed together through heat-bonding, the inside surface of the mask is provided with a slip pocket having an opening on one side used for a functional filter to be inserted into. The technical proposal of the utility model has the technical advantages of replacing the functional filter at any time, along with simple manufacturing method, convenient operation and replacement.

Description

Filter malicious protective mask

Technical field

The utility model relates to protective mask.

Background technology

Present mouth mask product is generally sewed up by several layers cotton yarn edge of materials and is made.Because its filter capacity is limited,, as the area of the heavy contamination of causing a disease, contain the environment of toxic dust etc., just need have as the mouth mask product of multiaspect filter effect more such as gas defence especially for some special use occasions.As increase layer of active carbon fiber filtering layer, and being sewed together with cotton yarn stacked adding as the intermediate layer, its manufacture method is comparatively complicated, and product cost is difficult to reduce, and its active carbon layer can't be changed at any time.

Summary of the invention

Be to provide a kind of manufacture method simple and be convenient to change the filter poison protective mask of its effective filter course invention order of the present utility model.The filter poison protective mask technical scheme that the utility model provides, its major technique content is: the malicious protective mask of a kind of filter, it is made of the fiber layer of cloth of gum sprayed cotton matter layer and gum sprayed cotton matter layer both side surface, periphery is adhesively fixed through heat seal, and this mouth mask inner surface is provided with the slash pocket that is used to insert functional filter of a side opening.

The malicious protective mask technical scheme of filter of the present utility model has adopted the heat seal mode to fix its each layer structure, and manufacture method is simple, make the efficient height, cost is low; Wherein also adopted the plug in construction that makes things convenient for the activated carbon filtration fibrage to change, personnel easy to use change the filtering material of using with new activated carbon filtration fibre plate at any time, and are very easy to use, improved its service efficiency.

Description of drawings

Fig. 1 is the three-dimensional structure diagram of the malicious protective mask of filter of the present utility model

Fig. 2 and Fig. 3 are respectively the two embodiment sectional structure charts at A-A place among Fig. 1.

The specific embodiment

The filter poison protective mask that the utility model proposes, the layer structure of one enforcement structure as shown in Figure 2, it is by being stacked to constitute as the gum sprayed cotton matter layer 1 that filters main body and the fiber layer of

cloth

2,3 of this gum sprayed cotton matter layer 1 both side surface, and its periphery is adhesively fixed through heat seal becomes the face shield of similar taper as shown in Figure 1.Side surface is provided with the slash pocket that is used to insert functional filter 4 of a side opening within it; The formation of this slash pocket can directly be established an opening on inboard fiber layer of cloth 2, go out to form the last lower fixed line 5,6 in slash pocket chamber along the upper and lower heat seal of this opening, inserts functional filters 4 such as activated carbon filtration fibrage in this slash pocket.The another kind of slash pocket is implemented structure: be overlying on inboard fiber layer of cloth 2 surfaces, the fixing slash pocket sheet 7 that forms slash pocket of two opposite sides heat seal at least, inserted functional filters 4 such as activated carbon filtration fibrage by the one side opening.
