Description

Antifog gauze mask of two pressure strips

Technical Field

The utility model belongs to the gauze mask field, concretely relates to antifog gauze mask of two pressure strips.

Background

In the aspects of medical care, virus protection and the like, the mask is the most basic protective tool, but the people wearing glasses wear the mask, which causes great inconvenience: the rising of the exhaled air from the upper edge of the mask tends to cause fogging of the glasses, thereby affecting the line of sight, which can have a significant impact when careful observation is required. Especially in the operation process, if the glasses of the doctor fog, the sight, judgment and operation of the doctor are easily influenced, so that a larger risk is increased for a patient, the operation success rate is influenced, even medical accidents can be caused in serious cases, and the eyes of pedestrians or riding people fog to cause great traffic safety hidden dangers.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an antifog gauze mask of two pressure strips based on labyrinth seal principle for solving above-mentioned problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides an antifog gauze mask of two pressure strips, includes the gauze mask body, the bridge of the nose department of gauze mask body is provided with first crease, gauze mask body surface is located first crease both sides and is provided with two bridge of the nose strips, first crease uplift forms the bar chamber, the surface of gauze mask body is provided with the covering of covering cloth bridge of the nose strip, be connected through setting up second seal weld and third seal weld between covering cloth and the gauze mask body, second seal weld and third seal weld and be used for fixed bridge of the nose strip.

As the utility model discloses a further optimization scheme, the gauze mask body is from the extroversion to the inside by waterproof cloth, melt-blown fabric, non-woven fabrics are constituteed, carries out the hot melt welding through the seal welding, for the basic structure of current gauze mask.

As the utility model discloses a further optimization scheme, the both sides of gauze mask body are provided with the ear area through the hot melt welding, the interlude of gauze mask body is provided with the second crease, first crease is all welded through the banding and is carried out the hot melt fixedly with the second crease, and first crease is used for the expansion to form the bar chamber, and the second crease then is the structure of current gauze mask for it is facial to expand the laminating, and the both ends of crease are fixed through the banding welding.

As the utility model discloses a further optimization scheme, first crease expandes the back and is provided with first seal welding between the cloth, makes the gauze mask body crooked to the cloth direction of covering, forms the bar chamber.

The beneficial effects of the utility model reside in that:

the utility model discloses a set up the bar chamber that two bridge of the nose strips and first crease formed for the gas flow of exhalation produces the labyrinth seal effect when passing through bridge of the nose strip clearance, makes this department's gas outflow reduce, and the gas major part of exhalation is discharged from gauze mask both sides and lower extreme, prevents effectively that glasses from hazing.

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a side sectional view of the present invention.

Fig. 3 is a schematic diagram of the principle model of the present invention.

In the figure: 1. a mask body; 2. a first fold; 3. a nose bridge strip; 4. sealing and welding; 5. covering with cloth; 6. a strip-shaped cavity; 7. first sealing and welding; 8. second sealing and welding; 9. third seal welding; 10. ear bands; 11. and a second fold.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in fig. 1-3, an antifog gauze mask of two pressure strips, including gauze mask body 1, gauze mask body 1 is from the extroversion to the inside by tarpaulin, melt-blown fabric, non-woven fabrics are constituteed, carry out the hot melt welding through the seal weld, the basic structure of current gauze mask, current gauze mask body 1 comprises three-layer raw and other materials, its four sides department all carries out the hot melt banding through the spot welder, the bridge of the nose department covers the bridge of the nose strip through covering 5 or turning over outwards through the non-woven fabrics of inlayer, and set up the seal weld with the bridge of the nose strip all around and fix.

Nose bridge department of gauze mask body 1 is provided with

first crease

2, 1 surface of gauze mask body is located first crease 2 both sides and is provided with two bridge of the nose strip 3, first crease 2 uplift forms bar chamber 6 when exhaling, the surface of gauze mask body 1 is provided with covering 5 covers bridge of the nose strip 3, connect through setting up second seal weld 8 and third seal weld 9 between covering 5 and the gauze mask body 1, second seal weld 8 and third seal weld 9 are used for fixed bridge of the nose strip 3.

Through setting up two bridge of the nose strips 3, and form between two bridge of the nose strips 3 and extend strip chamber 6 to the gauze mask body 1 outside, when using, at first wear the gauze mask, make two bridge of the nose strips 3 laminating bridge of the nose, when the gas of exhalation rose, successively passed through the clearance between two bridge of the nose strips 3 of both sides and the face, reduced gas flow.

The both sides of gauze mask body 1 are provided with ear area 10 through the sweat soldering, and the interlude of gauze mask body 1 is provided with second crease 11, and first crease 2 all carries out the hot melt through edge sealing welding 12 with second crease 11 and fixes, and first crease 2 is used for the expansion to form bar chamber 6, and second crease 11 then is the structure of current gauze mask for it is facial to expand the laminating, and the both ends of crease are fixed through edge sealing welding 4.

A first seal weld 7 is arranged between the unfolded first fold 2 and the covering cloth 5, so that the mask body 1 is prevented from being insufficiently unfolded.

Wherein, the bar chamber 6 that two nose roof beam strips 3 formed makes gas flow through, produces the labyrinth seal effect for this department's gas outflow reduces, and the gas of exhaling is most discharged from gauze mask both sides and lower extreme, and wherein, the labyrinth seal principle is: the air flows from the high-pressure end to the low-pressure end under the action of the pressure difference between the front and the back of the seal, the air flow speed is accelerated and the pressure is reduced when the air passes through the gap between the nose bridge strip 3 and the face, and when the air flows into the strip-shaped cavity 6 from the gap, the air flow forms strong vortex due to the sudden expansion of the area, the resistance is formed, and the leakage is reduced.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
