Abstract

The utility model provides a dustproof nasal aspirator. The dustproof nasal aspirator comprises a gas exchange cavity, air filter layers, filter support frames and elastic head hoops, wherein an exhaust port is formed in front of the gas exchange cavity, and a one-way valve is arranged in the exhaust port; two nasal plug ports corresponding to nares are formed behind the gas exchange cavity; an insertion opening is arranged at each of two ends of the gas exchange cavity, one end of each elastic head hoop is inserted in the corresponding insertion opening, the filter support frame is arranged in the elastic head hoop; and the air filter layer wraps the filter support frame. The dustproof nasal aspirator has the following advantages: clean air can be directly introduced into the nasal cavity according to the characteristic that people breathe by the nasal cavity, so that the inhaled air is filtered, the covering area of the aspirator to the face is greatly reduced, and the sense of stuffiness can be eliminated; the air filter layer extends in a longer range in the elastic head hoop, so that the air filter area is greatly increased, and the air aspiration resistance is reduced; the larger one-way valve is close to the outside of nares, so that the expired waste gas is directly exhausted, waste gas cannot be detained, and the breath smoothness is guaranteed.

Description

Dustproof inhaler

Technical field

The utility model relates to a kind of air cleaning unit of protecting human respiratory, can be worn over micronic dust and other noxious pollutants in the filtered air on one's body at any time easily.

Background technology

At present; Known tyre protective device for respiration is various mouth mask or gas mask; Their common feature is that mouth, nose and part face are isolated these positions and outside air with mask seal, and portion forms a relative confined space within it, carries out Gas Exchange through the face shield and the external world.But these protective covers exist poorly sealed and temperature lets the human face that the shortcoming of sultry sense is arranged when higher.

Summary of the invention

In order to overcome mouth mask or other protective face masks are poorly sealed and make facial sultry shortcoming easily, the utility model provides a kind of dustproof inhaler of the succinct human body respiration characteristics that are more suitable for.

The utility model solves the technical scheme that its technical problem adopted: a kind of dustproof inhaler; It is characterized in that; Comprise Gas Exchange chamber, air filtration layer, filter bracing frame and elasticity head hoop, be provided with exhaust outlet, check valve is housed in exhaust outlet in the front in Gas Exchange chamber; Be provided with two nasal obstruction mouths corresponding with the nostril in the back in this Gas Exchange chamber; Two ends in this Gas Exchange chamber are provided with socket, and an end of described elasticity head hoop inserts in this socket, in this elasticity head hoop, the filtration bracing frame is housed, and filter at this and coat the air filtration layer on bracing frame.

Described check valve is processed by sheet rubber, one side its on one side with exhaust outlet in be connected.

Described elasticity head hoop comprises that the cross section is the head hoop main body of C shape and is connected the ring-type of one of which end or the head hoop plug of C shape, is provided with a plurality of discontinuous hollow holes on the head hoop main body.

Described filtration bracing frame is made up of two elastic supports and the bracing frame plug that is connected the one of which end, and the elastic support of two arcs and bracing frame plug are connected to fork configuration; Described air filtration layer adopts filter cloth to twine and is wrapped on two elastic supports; This bracing frame plug inserts in the hole of described head hoop plug ordinatedly, and together inserts in the socket at two ends, described Gas Exchange chamber tightly; The elastic support that is enclosed with filter cloth embeds in this head hoop main body.

Described Gas Exchange chamber, filtration bracing frame and elasticity head hoop are processed by plastics or metal.

The beneficial effect of the utility model is: the applying people directly feed nasal cavity with the characteristics of nose breathing with the air of cleaning, guarantee that inhaled air all is through filtering, reduced the masked area of respirator to face simultaneously greatly, eliminating feeling of oppression and heat; The air filtration layer extends in the longer scope in the elasticity head hoop, has increased the air filtration area greatly, has reduced inspiratory resistance; Directly discharge the waste gas of breathing out bigger outside, check valve next-door neighbour nostril, can not be detained waste gas, has ensured breathe unimpeded.

The specific embodiment

Referring to Fig. 1-Figure 12, a kind of dustproof inhaler of the utility model is characterized in that, comprises Gas Exchange chamber 4, air filtration layer 2, filters bracing frame 3 and elasticity head hoop 1, is provided with exhaust outlet 8 in the front in Gas Exchange chamber 4, and check valve 5 is housed in exhaust outlet 8.Be provided with two nasal obstruction mouths 6 corresponding with the nostril in the back in this Gas Exchange chamber 4; Be provided with socket 7 at the two ends in this Gas Exchange chamber 4.In this elasticity head hoop 1, be equipped with and filter bracing frame 3, filter at this and coat air filtration layer 2 on bracing frame 3.

Described check valve 5 is processed by sheet rubber, while it uses being connected in air bleeding valve fixed strip 9 and the exhaust outlet 8.

Referring to Figure 10-Figure 12, described elasticity head hoop 1 comprises that the cross section is the head hoop main body 11 of C shape and is connected the ring-type of one of which end or the head hoop plug 12 of C shape, on head hoop main body 11, is provided with a plurality of discontinuous hollow holes 13, is used for ventilation.

Referring to Fig. 7-Fig. 9, described filtration bracing frame 3 is made up of two elastic supports 31 and the bracing frame plug 32 that is connected the one of which end, and the elastic support 31 and the bracing frame plug 32 of two arcs are connected to fork configuration.Described air filtration layer 2 adopts filter cloth to twine and is wrapped on two elastic supports 31, and this bracing frame plug 32 inserts in the hole of described head hoop plug 12 ordinatedly, and together inserts tightly in the socket 7 at 4 two ends, described Gas Exchange chamber; The elastic support 3 that is enclosed with filter cloth embeds in these head hoop main bodys 11, and described filter cloth is that one or more of cotton, gauze or active carbon cloth are composited.

Described Gas Exchange chamber 4, filtration bracing frame 3 and elasticity head hoop 1 are processed by plastics or metal.

The method for using of the utility model is: the elasticity head hoop 1 of both sides is worn over the rear portion of the cheek of both sides to head, two nasal obstructions of 4 back, Gas Exchange chamber mouthfuls 6 are adjacent to the nostril.When nasal cavity is air-breathing, form negative pressure in the Gas Exchange chamber 4; The rubber check valve 5 of normally off is closed; The air filtration layer 2 that outside air can only see through in the elasticity head hoop 1 gets in the filtration bracing frame 3, and gets into the human body nasal cavity through the nasal obstruction mouth 6 in Gas Exchange chamber 4, forms air intake passage.Air pressure when nasal cavity is exhaled in the Gas Exchange chamber 4 is opened rubber check valve 5 because the elasticity of rubber check valve 5 is very little and valve block over against the nostril, nostril exhalation ground vapour fails to be convened for lack of a quorum and washes valve overwhelming majority gases open and from then on discharge.

The utility model is integrated into air filtration layer 2 and gas exchanger on the wide about 2 centimetres elasticity head hoop 1; Head is clamped at elasticity head hoop 1 two ends; The Gas Exchange chamber 4 of middle part has nasal obstruction mouthfuls 6 to communicate with the nostril; The part that contacts with skin like this is merely the two ends and nasal obstruction mouth 6 of elasticity head hoop 1, has reduced contact area to greatest extent, eliminates feeling of oppression and heat.The air that nasal obstruction mouth 6 is close to wing of nose assurance entering nasal cavity all is through filtering.The air filtration layer is rolled into by multiple filtration cloth, and the flexible supporter of its core 31 formation inner spaces communicate with Gas Exchange chamber 4, for nasal cavity provides sufficient pure air.
