Description

The warm keeping structure of eye nose protective cover attractive in appearance

Affiliated field: daily necessities, protective articles.

Background technology:

2011-12-12, the heavy snow solar term have passed through, and a piercing cold wind.Pedestrian on the road by bike, rides electric bicycle, many people Dai Qi mouth mask.The other day, when having a dense fog, air pollution is serious, and mouth mask also is many people's selection.Certainly, compared with SARS in those days, the streetful mouth mask is wanted better.

At coal yard, the place of serious pollutions such as building site, snoot formula respirator is general selection.Though ugly, good for health, do not wear not all right yet.In many protection place, glasses also are the articles for use that people will select.

Medical mask, the snoot respirator often has the multiple filtration layer, as activated carbon filter layer, sterilizing layer etc.

During the broiling summer, some place, for health, mouth mask usually also will have on, and really feels bad, can not.

Summary of the invention: the present invention is using mouth mask, safety goggles in order to solve people, some drawbacks that respirator etc. are felt, as when wearing masks, it is inconvenient to speak, and winter can be at glasses upper fogging gas, and summer is sultry, the snoot respirator is too stupid, is difficult to see, a kind of eye nose protective cover attractive in appearance of special proposition.This protective cover adopts safety goggles to add the preceding respirator structure of nose, by the air inlet of leg of spectacles side, through filtering layer, delivers to the preceding breathing of nose, and the present invention gives a kind of electrothermal heater that utilizes air is carried out pre-warmed warm keeping structure.Have advantages such as simple in structure, elegant in appearance, easy to maintenance, economical and practical, can extensively apply to the many places that need the healthy prevention in people's production, the life, the protection people masses' is healthy.

Description of drawings: Fig. 1 the present invention wears schematic diagram, and Fig. 2 is general structural representation of the present invention, and Fig. 3 is a kind of warm keeping structure schematic diagram.

The specific embodiment: as shown in Figure 1, of the present inventionly wear equally with common spectacles, support by leg of spectacles and nose clip.

As Fig. 2,1 expression air intake, 2 expression air filtration layers, it should filter out pellet and some pernicious gases of most of M2.5 level, 3 expression air ducts, 4 expression lenses, 5 expression glasses top edges, 6 expression nose cups, its width is generally 1.5 times of nose.7 expression filtrate enclosing covers, the button of 8 expression enclosing covers uses screw fastening also passable.10 expression external gas source inlets are as oxygen, air etc.The 9th, key of the present invention, the air duct of walking along the glasses lower limb is isolated nose cup and glasses simultaneously, and the air duct between them is blocked.

Because filtrate of the present invention can adopt fully and use at mouth mask, snoot respirator, its air percent of pass is also with reference to its design, and suitable as the area fundamental sum respirator of the right and left, just stroke has been grown.The present invention can use plastics manufacturing and the existing respiratory products of suitable contact human body similar.In winter, the human body inhaled air is gone into from the both sides ear, goes into much better compared with the front of mouth mask, the air of breathing out is gone out along advancing air channel at the inner warm cheek earlier of nose cover again, and part of waste heat is absorbed by passage again, can be sucked the air utilization next time, so, warming effect is arranged.Summer, again because this product is hard material manufacturings such as plastics, more nice and cool than the bafta that mouth mask is such.

The design of nose cup of the present invention and leg of spectacles is convenient to further promote its heat-preserving function, as can additional power source, and heating.Fig. 3 provides a kind of enforcement structure.Among Fig. 3,11 represent the air duct of eye nose protective covers, 12 expression external power supply jacks, and it is better that power supply uses the 3.7v of battery of mobile phone herein, and charging can be compatible, saving and convenient.13 expressions connect lead, the outside earthenware of wrapping up in asbestos cloth of 14 expressions, and in fact, the design temperature of this structure generally has only tens degrees centigrade, gives enough safeguard protections here.The 15th, heating wire is determined its numerical value according to supply voltage and design temperature.

It has often been said that people's pin is not cold, just sensation is warm, and in fact, inhaled air is not cold, and also sensation is warm.Have a try.

Claims (2)

1. the warm keeping structure of eye nose protective cover attractive in appearance is the substitute products of a kind of mouth mask and respirator, and it is characterized in that: this protective cover is made of glasses and nose cup, and the air duct of this nose cup is on leg of spectacles, and passage contains the heating warm-keeping structure.

2. the warm keeping structure of eye nose protective cover attractive in appearance as claimed in claim 1 is characterized in that this heating arrangement is to connect heating wire by external direct current power supply to constitute.
