Abstract

The utility model relates to a high efficiency multifunctional fission type mask which is composed of a nose mask (1), a connecting soft pipe (2) and an air filter (3). The utility model is characterized in that the air filter (3) is provided with an air filtration cavity (S) and a clear air storage cavity (F), the inner of the clear air storage cavity (F) is also provided with an air freshener hidden box (16), and the inner of the nose mask (1) is provided with an inspiratory one-way valve (9), an expiratory one-way valve (10) and a sealing ring (8). The utility model has the advantages of many functions and convenient use. The high efficiency multifunctional fission type mask can be used for preventing dust and poison with high efficiency and is suitable for various places which need to prevent the dust and the poison. The high efficiency multifunctional fission type mask can also be used for medical treatment and health care and can be used as a high efficiency oxygen input mask.

Description

The split type mouth mask of high-efficiency multi-function

The utility model belongs to a kind of split type mouth mask, and it is widely used in places such as various dustproof, gas defences, medical treatment, health care.

At present existing dustproof, the integrated mouth mask of gas defence, because oral cavity, nasal cavity are all covered, relatively large with the cavity that face forms, the carbon dioxide that makes human body breathe out is remaining more in cavity, and the time of staying is long, and this just not only influences communication, once rest on too many carbon dioxide in the cavity before also can making nasal cavity repeat to suck, cause oxygen supply deficiency, unhappy etc., add and do not design the fresh air storage chamber, make inspiratory resistance bigger.

The utility model is exactly at above-mentioned deficiency, proposes a kind of and covers nasal cavity, thereby do not influence communication, the cavity that forms with face is little, the carbon dioxide less residue of breathing out, efficient dustproof, the gas defence that inspiratory resistance is little also takes into account the split type mouth mask of medical treatment, health care.

Accompanying drawing 1, the whole connection layout of the split type mouth mask of high-efficiency multi-function.

Accompanying drawing 2, nose cup master diagrammatic sketch.

Accompanying drawing 3, nose mask A-A cut-away view.

Accompanying drawing 4, air filter master diagrammatic sketch.

Accompanying drawing 5, air filter B-B cut-away view.

Concrete structure of the present utility model and content are described in detail as follows by reference to the accompanying drawings:

With reference to accompanying drawing 1: this mouth mask by nose cup (1), connect flexible pipe (2), air filter (3) three is partly formed.

With reference to accompanying drawing 2,3: nose cup (1) is that nose cup skeleton (4), breather cheek valve (9), expiratory one-way valve (10), expiration baffle (6), sealing rubber ring parts such as (8) are formed.

With reference to accompanying drawing 4,5: air filter (3) by housing (19), outer shield (12), interior guard shield (18), magnet (15), inhale iron plate parts such as (14) and form.

Its main points are: be provided with hinge (11) below housing (19) front end of cleaner (3), connect outer shield (12) on it, be equipped with on (12) and inhale iron plate (14); The centre of housing (19) above the front end is provided with magnet (15), inside is provided with step (D) can make housing (19) inner under the isolation of interior guard shield (18), can form filtering chamber (S) and fresh air storage chamber (F), filtering chamber (S) is owing to increased the area and the volume of filtering, make it efficient dustproof, gas defence, and the stored fresh air of fresh air storage chamber (F) can reduce inspiratory resistance effectively, and interior shield (18) is provided with air freshener and hides box (16), after putting into freshener, can improve the air quality after the filtering effectively; Air after filtering; the interface of giving vent to anger (13) by housing (19) both sides; arrive nose cup (3) two side-inlets (7) through tube connector (2) again; enter nasal cavity by breather cheek valve (9); when nasal cavity gives off carbon dioxide; by expiratory one-way valve (10) combustion gas; because nose cup (3) has adopted and has only covered nasal cavity; exceed and design not hit nose; the carbon dioxide remaining quantity and the time of staying have so just been reduced; sealing ring (8) is that the air that prevents filtered directly enters nasal cavity, and (6) are the expiratory one-way valve baffles, and it guarantees the expiratory one-way valve operate as normal effectively.

Use this mouth mask, need hook (17) with air filter (3), hang over the bongrace top securely, need dustproof or gas defence, dustproof or gas defence filter core are put into filtering chamber (S), if need medical treatment or health care, then filtering chamber (S) is put in medical treatment or health medicine core, again nose cup (1) is gone up (O) shape groove of elastic cord base (5) and set up elastic cord, with the degree of tightness zone circle on the head hindbrain, make nose cup (1) cover toward nasal cavity, can come into operation.

The utility model is compared with existing mouth mask, have simple and reasonable, function is many, easy to use, dustproof, characteristics such as gas defence is effective, separately nose cup is made oxygen therapy cover and is used, and can improve its oxygen therapy efficient.
