Description

Integral air purifying nasal mask

Technical field

This utility model relates to personal protective equipment, specifically a kind of Integral air purifying nasal mask。

Background technology

Traditional filtering type anti-dust nose mask, is made by the effect of filter, filters the dust, smog or the metal dust that contain in air, stops particulates emission to enter human lung。It is mainly with the self-suction dustproof nose cup of the parts compositions such as filtrate, inlet valve, outlet valve。But self-suction dustproof nose cup makes expiration and air-breathing be in same nose cup, user is allowed to feel suffocated sense in using。Meanwhile, the exhalation vents in nose cup when user air-breathing, can be directly sucked in without media filtration, purification air to nose cup air-breathing position, do not reach user suck purify air effect。

Summary of the invention

The purpose of this utility model is in that: for above-mentioned the deficiencies in the prior art, it is provided that feel suffocated sense, nose cup of a kind of practical, simple in construction, elimination only exists the Integral air purifying nasal mask purifying this process of air-breathing。

The technical solution adopted in the utility model is, a kind of Integral air purifying nasal mask, including cover body and the type frame that is connected with cover body, described cover body is mainly by having the inner shell of air outlet and having the shell of air inlet and form, and is provided with filter element and mini fan between inner shell and shell；The oral area profile molded line of described type frame and the profile molded line of human body nasal region are mutually matched。

Described filter element is supported by the filter stand being arranged on inner shell。

Described type frame oral area is provided with flexible seal ring, and the oral area profile molded line of this flexible seal ring and the profile molded line of human body nasal region are mutually matched。

Further, when described nose cup is sleeved on human body, form sealing space by flexible seal ring and human body nasal region。

The beneficial effects of the utility model are: this utility model is practical, simple in construction not only, nose cup only exists purification this process of air-breathing, and solves the expiration of oral area and nose and problems such as sense, clean-up effect is bad, inspiratory resistance is big of feeling suffocated that air-breathing is in same nose cup。

Accompanying drawing explanation

Below in conjunction with accompanying drawing, this utility model is further described。

Fig. 1 is structural representation of the present utility model。

Fig. 2 is assembly state diagram of the present utility model。

Code name implication in figure: 1 cover body；11 inner shells；12 shells；13 filter elements；14 filter stands；15 mini fans；2 type frame；21 flexible seal rings。

Detailed description of the invention

Shown in Fig. 1, Fig. 2: this utility model is a kind of Integral air purifying nasal mask, including cover body 1 and the type frame 2 that is connected with cover body 1。

Above-mentioned cover body 1 is main to be made up of with the shell 12 having air inlet the inner shell 11 having air outlet, the air outlet number of its inner shell 11, size and arrangement are determined according to practical situation, and all air outlets of inner shell 11 try one's best centralized arrangement, the pressure to ensure each air outlet is balanced, it is consistent to flow to；The air inlet number of shell 12, size and arrangement are determined according to practical situation。

Filter element 13 and mini fan 15 it is provided with between above-mentioned inner shell 11 and shell 12, this filter element 13 and mini fan 15 are arranged with the order of left-to-right, this filter element 13 and mini fan 15 are by the filter stand 14 that to be arranged on inner shell 11 corresponding respectively, frame, the filter stand 14 installing filter element 13 and the frame installing mini fan 15 installation site in cover body 1, determine according to needs of production。Wherein, by driven by motor, it rotates mini fan 15。In the present embodiment, described filter element 13 is supported by the filter stand 14 being arranged on inner shell 11。

The oral area profile molded line of above-mentioned type frame 2 and the profile molded line of human body nasal region are mutually matched。In order to better cushion, improve obturation effect, described type frame 2 oral area is provided with flexible seal ring 21, and the oral area profile molded line of this flexible seal ring 21 and the profile molded line of human body nasal region are mutually matched。When nose cup is sleeved on human body, form sealing space by flexible seal ring 21 and human body nasal region。Flexible seal ring 21 in the present embodiment is silica gel ring (according to practical situation, it is also possible to select the sealing ring of other materials)。In order to after making the contact position of profile molded line profile molded line corresponding to place on nose cup of user nasal region effectively airtight and airtight its contact surface is less from each other, taking silica gel ring at cover body 1 is 0.05～1cm to the height on wing of nose direction, it is preferable that 0.5cm。So, just well avoid the profile molded line at nose cup place excessive with the contact position contact area of the profile molded line of corresponding nasal region, make the skin of contact portion produce a large amount of perspiration and penetrate in nose cup。

Above-mentioned type frame 2 circularizes structure, and with type frame 2 for benchmark, inner shell 11 is stuck on the annular inner surface on the left of type frame 2, inner shell 11 is cased with filter stand 14, filter stand 14 is provided with filter element 13。It addition, at inner shell 11 on the direction of shell 12, inner shell 11 is also equipped with miniature electric blower fan 15(miniature electric blower fan 15 can also be needed to be arranged on cover body 1 inner surface according to actual installation)。Shell 12 overlaps by being buckled on the annular outer surface on the left of type frame 2。It is snapped with silica gel ring with the molded line of place type frame 2 on the right side of the type frame 2 that nasal region profile molded line mates。

Above-mentioned cover body 1 and type frame 2 be monolithically fabricated unidirectional breathing space, and nose cup is not provided with the passage of exhalation gas。

In order to improve purification function, filter element 13 is made up of at least one of which filter material layer, and the filter material layer of the present embodiment is made (can also be other filter material materials according to practical use, such as carbon fiber felt etc.) by ultrafine fiber felt。Filter the dust, smog or the metal dust that contain in air, stop particulates emission to enter human lung。

Work process: be worn on nose by fixing for nose cup by the elastic rope band on Integral air purifying nasal mask, nose cover is combined in nose cup, open mini fan 15, draw air into the air inlet on shell 12, purify through being fixed on the internal corresponding filter material layer of cover body 1, behind the gas outlet on inner shell 11, the oral area of silica gel ring 21 suck in the nasal cavity of nose, complete the breathing process of nose。Breathed out gas by the mouth of user, complete the cyclic process of an expiration, air-breathing, solve the oral area of other similar techniques and the expiration of nose and feel suffocated defect and the deficiencies such as sense, clean-up effect is bad, inspiratory resistance is big that air-breathing is in same cover body。

Concrete technical scheme is only in order to illustrate this utility model above, is not intended to limit。Although this utility model being described in detail with reference to above-mentioned concrete technical scheme, it will be understood by those within the art that: above-mentioned concrete technical scheme still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and scope of the present utility model。
