Abstract
The utility model relates to a mouth-nose mask respirator, comprising a convex nose cup with ties, an expiratory valve arranged on the front of the nose cup, an exhalation valve arranged on the lower part of the nose cup, the an exhalation valve is sealed with a filtrating box with sorbent inside and a fine filtering layer made of electric glass fiber sealed on the upper of the sorbent which is inside the filtrating box and on the inner wall of the box body of the filtrating box. The fine filtering layer also comprises a frame and the glass fiber is fixed on the frame which is sealed on the inner wall of the filtrating box. As the utility mode has a fine filtering layer in the filtrating box of the mouth-nose mask respirator, the filtering effect of the mask respirator is improved and the application area of the utility model is enlarged; the mouth-nose mask respirator has a filtering efficiency of the oil and mist which has a diameter of 0.14-0.17 um of more than 95 percent, the utility model has, particularly, a filter effect on the harmful organisms such a various germina.
Description
Technical field
The utility model relates to a kind of breathing mask, is specially a kind of mouth and nose bell-type breathing mask.
Background technology
Existing mouth and nose bell-type breathing mask comprises a raised type oronasal mask, have on the oronasal mask to be fixed with and be used for oronasal mask and the fixing frenulum of human body head, front portion in oronasal mask is fixed with outlet valve, bottom in oronasal mask is fixed with inlet valve, inlet valve through potted component (as sealing ring) and end face air admission hole is arranged, filter poison box that adsorbent (as active carbon) is housed in it is connected and fixed.When human body is worn the breathing of mouth and nose bell-type breathing mask, treat the filtration of air filtering adsorbent in filtering malicious box, in inlet valve inlet port nose cup, for human body provides clean air, the gas that human body is breathed out is discharged by outlet valve again.Absorbent filtering performance in the filter poison box of existing mouth and nose bell-type breathing mask is limited, the filter effect of its special harmful substance less to some particles (as harmful organism factors such as mist of oil, oil smoke, particularly germs) is not satisfactory, therefore, the use occasion or the application of existing mouth and nose bell-type breathing mask are subjected to certain restriction.
Summary of the invention
The utility model solves the filter effect that existing mouth and nose bell-type breathing mask adopts single absorbent filtering to bring and has circumscribed problem, and a kind of suitable application area, occasion is wide in range and filter efficiency is high mouth and nose bell-type breathing mask are provided.
The utility model is to adopt following technical scheme to realize: mouth and nose bell-type breathing mask, comprise the raised type oronasal mask that has frenulum on it, the oronasal mask front is fixed with outlet valve, the oronasal mask bottom is fixed with inlet valve, be fixed with the filter poison box that adsorbent is housed in it with the inlet valve sealed attachment, the adsorbent top in the malicious box of filter, the fine filtering layer that is made of glass filter paper arranged with the malicious box inboard wall of cartridge sealing and fixing of filter.Like this, filter adsorbent and glass filter paper two filter layers are arranged in the malicious box.The special harmful substance that can not be adsorbed the abundant filtering of agent is passed through the filtration of fine filtering layer again, reaches abundant filtration, improves the purpose of filter effect, thereby overcome the deficiency that existing mouth and nose bell-type breathing mask use occasion is subject to certain restrictions.Also available other filtering material of glass filter paper that constitutes the fine filtering layer substitutes as the third human relations filter cloth or filter paper.
The fine filtering layer also comprises a framework, glass filter paper elder generation sealing and fixing on this framework, framework again sealing and fixing on the inwall of the malicious box of filter.The fine filtering layer adopts the structure that has framework, is convenient to fine filtering layer and the assembling of filtering malicious box, thereby also makes the assembling of whole breathing mask easier.
The utility model has improved the filter effect of breathing mask by increase the fine filtering layer in the filter poison box of existing mouth and nose bell-type breathing mask, has enlarged its application; This mouth and nose bell-type breathing mask more than 95%, particularly has special filter effect to harmful organism factors such as dust and various germ, viruses to the filter efficiency of the mist of oil of radius 0.14-0.17um
Description of drawings
Fig. 1 is structural representation resistance of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
The specific embodiment
Mouth and nose bell-type breathing mask, comprise the raised type oronasal mask 2 that has frenulum 1 on it, the oronasal mask front is fixed with outlet valve 3, the oronasal mask bottom is fixed with inlet valve 4, be fixed with the filter poison box 6 that adsorbent 5 is housed in it with the inlet valve sealed attachment, the adsorbent top in the malicious box of filter, the fine filtering layer 7 that is made of glass filter paper arranged with the malicious box inboard wall of cartridge sealing and fixing of filter.Glass filter paper adopts 6209 models.The fine filtering layer also comprises a framework 8, glass filter paper elder generation sealing and fixing on framework, framework again sealing and fixing on the inwall of the malicious box of filter.Framework 8 can be made of plastics, and its shape is identical with the malicious box cavity shape of filter.
Glass folded filter paper moulding (filter paper before not folding is microscler olive-shaped, and the filter paper behind the folding forming is and malicious box cross sectional shape of filter or the consistent circle of framework cross sectional shape).Foldable formed filter paper has increased filter area than plane filter paper.Receive the limit around the glass filter paper.Glass filter paper (perhaps directly is adhered on the inwall of the malicious box of filter) by receiving airtight being adhered on the framework in limit; Framework also adopts airtight bonding fixed form with the malicious box inwall of filter.
With the filter poison box box neck that installs the fine filtering layer down, the smooth plastics web plate 9 of packing into is put a layer starching screen cloth sheet again,, loads onto bottom and screws in adsorbent (the employing KZ15-1 impregnated carbon) box body of packing into special container.A rubber seal of the interior placement of neck cover that will be fixed in the inlet valve on the oronasal mask screws with the malicious box neck of filter, finishes whole the assembling.
