Abstract
The utility model discloses an improved mask for infectious disease prevention. The improved mask comprises a mask body. An outer filter layer and an inner filter layer are arranged in the mask body and respectively provided with a vibration membrane, a sealed air chamber is formed between the vibration membranes, a plurality of ventilation bypasses are formed between the outer filter layer and the inner filter layer, inlets of the ventilation bypasses are formed in the outer filter layer, outlets of the ventilation bypasses are formed in the outer edge of the inner filter layer, and a medicine bag layer is arranged on the inner side of the inner filter layer. By means of the improved mask, the defects in the prior art can be overcome; after the improved mask is worn, the sealing performance is good, and influences on language communication are small.
Description
Technical field
The utility model relates to a kind of infectious disease prevention articles for use, especially a kind of improved infectious disease prevention mouth mask.
Background technology
In the treatment nursing process of infectious disease, need to use mouth mask to protect respiratory system.Chinese utility model patent CN202842440U discloses a kind of Novel infectious disease mouth mask, can change epidemic prevention drug according to actual conditions, practical.But this mouth mask exists, wear rear communication difficulty, edge only depends on mouth mask and facial gluing, sealing, and sealing effectiveness is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of improved infectious disease prevention mouth mask, can solve the deficiencies in the prior art, wears rear and good airproof performance, little on communication impact.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of improved infectious disease prevention mouth mask, comprise mouth mask body, in mouth mask body, be provided with outer filter course and inner filtration layer, on described outer filter course and inner filtration layer, be respectively arranged with a vibrating diaphragm, between vibrating diaphragm, be provided with sealed air chamber, be provided with several ventilation bypasses between outer filter course and inner filtration layer, the import of ventilation bypass is arranged on outer filter course, outlet is arranged on the outward flange of inner filtration layer, and the inner side of described inner filtration layer is provided with anther sac layer.
As preferably, between described outer filter course and inner filtration layer, be provided with activated carbon adsorption layer.
As preferably, in described outer filter course and inner filtration layer, be respectively arranged with several helical form ventilation capillaries.
The beneficial effect that adopts technique scheme to bring is: the utility model is by arranging vibrating diaphragm, and the transmission sound of wearer being sent by vibrating diaphragm is gone out.Volume loss late can be controlled in 15%.In the process of wearer breathes, air is in outer filter course inlet port cover body, portion of air enters ventilation bypass, and spray at the outward flange of inner filtration layer, so just the facial contact mouth mask body and wearer has partly formed outside mobile sealing air-flow, make in breathing process outside air can be from mouth mask body and facial gap inflow entrance cover body inner.The position of anther sac layer is improved to inside by outside, can extend anther sac layer more than 50% service life, in addition, because anther sac layer approaches wearer's respiratory system, can add as required multiple antiviral Chinese medicine, when wearing, carry out antiviral auxiliary curing.Between outer filter course and inner filtration layer, being provided with activated carbon adsorption layer can reduce in extraneous irritative gas inlet port cover body.Helical form ventilation capillary can add long air mobile total length in filter course and inner filtration layer outside, improves filter effect, so just can on the constant basis of maintenance filter effect, reduce the thickness of mouth mask body.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a specific embodiment of the utility model.
In figure: 1, mouth mask body; 2, outer filter course; 3, inner filtration layer; 4, vibrating diaphragm; 5, sealed air chamber; 6, ventilation bypass; 7, anther sac layer; 8, activated carbon adsorption layer; 9, helical form ventilation capillary; 10, resonance bar.
The specific embodiment
With reference to Fig. 1, specific embodiment of the utility model comprises mouth mask body 1, in mouth mask body 1, be provided with outer filter course 2 and inner filtration layer 3, on described outer filter course 2 and inner filtration layer 3, be respectively arranged with a vibrating diaphragm 4, between vibrating diaphragm 4, be provided with sealed air chamber 5, between outer filter course 2 and inner filtration layer 3, be provided with several ventilation bypasses 6, the import of ventilation bypass 6 is arranged on outer filter course 2, outlet is arranged on the outward flange of inner filtration layer 3, and the inner side of described inner filtration layer 3 is provided with anther sac layer 7.
It should be noted that between described outer filter course 2 and inner filtration layer 3 and be provided with activated carbon adsorption layer 8.
In addition, in described outer filter course 2 and inner filtration layer 3, be respectively arranged with several helical form ventilation capillaries 9.
Wherein, being connected with resonance bar 10 between two vibrating diaphragms 4, is interference fit between resonance bar 10 and two vibrating diaphragms 4.Add resonance bar 10, can further volume loss late be controlled in 5%, and can obviously improve tonequality.Outer filter course 2 and inner filtration layer 3 adopt Electrostatic Absorption filter course, and this material is prior art, in the various protective articles such as personal protection mouth mask such as 3M company, is widely used, and are not described in detail in this its material and microstructure and form.
Operation principle of the present utility model is: the utility model is by arranging vibrating diaphragm 4, and the transmission sound of wearer being sent by vibrating diaphragm 4 is gone out.In the process of wearer breathes, air is in outer filter course 2 inlet port cover bodies 1, portion of air enters ventilation bypass 6, and spray at the outward flange of inner filtration layer 3, so just in mouth mask body 1 and wearer's facial contact, partly form outside mobile sealing air-flow, made in the breathing process outside air can be from inflow entrance cover body 1 inside mouth mask body 1 and facial gap.The position of anther sac layer 7 is improved to inside by outside, can extend anther sac more than 50% service life, in addition, because anther sac layer 7 approaches wearer's respiratory system, can add as required multiple antiviral Chinese medicine, when wearing, carry out antiviral auxiliary curing.Between outer filter course 2 and inner filtration layer 3, being provided with activated carbon adsorption layer 8 can reduce in extraneous irritative gas inlet port cover body 1.Helical form ventilation capillary 9 can add long air mobile total length in filter course 2 and inner filtration layer 3 outside, improves filter effect, so just can on the constant basis of maintenance filter effect, reduce the thickness of mouth mask body 1.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
