Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be realized and that various changes to the invention may be made without departing from the spirit and scope of the present invention. The following more detailed description of the embodiments of the present invention is not intended to limit the scope of the invention, as claimed, but is presented for purposes of illustration only and not limitation to provide the best mode contemplated for carrying out the invention and to enable any person skilled in the art to practice the invention. Accordingly, the scope of the invention is to be limited only by the following claims.

Example 1

As shown in fig. 1 to 8, the anti-fogging goggles of the present embodiment include a goggle frame 100, lenses 200 disposed on the goggle frame 100, defogging members, and a fixing band 600.

In fig. 1, the defogging component includes a first defogging brush 300, a second defogging brush 400, and a rotating shaft 500 for fixing the first defogging brush 300 and the second defogging brush 400 on the lens 200, the first defogging brush 300 includes a first plastic soft framework 310, an iron core 320 disposed in the first plastic soft framework 310, and a silver 330 disposed on the surface of the first plastic soft framework 310, the iron core 320 is in a block shape, the length of the iron core is 10mm, the width of the iron core is 1mm, the iron core is tightly attached to the inner surface of the lens 200, the silver 330 is a better moisture absorption material, the thickness of the silver is 0.5mm, in this embodiment, a soft hydrophilic material, such as nano cotton, may also be used, so as to avoid scratching the lens 200; the second defogging brush 400 comprises soft magnetic strips 410 and a silica gel layer 420 arranged on the surfaces of the soft magnetic strips 410, is arranged opposite to the first defogging brush 300 and is tightly attached to the outer surface of the lens 200, and the thickness of the silica gel layer 420 is 0.5 mm; the first defogging brush 300 moves in the same direction around the rotation shaft 500 under the magnetic force of the second defogging brush 400.

Further, the silica gel layer 420 is detachably sleeved on the outer side of the soft magnetic strip 410. Also, the tampon 330 can be detachably sleeved on the outer side of the first plastic soft frame 310, or the tampon 330 can be adhered by a magic tape on the side close to the lens, so that the tampon 330 can be replaced after long-term use.

Compare among the prior art, the defogging structure of goggles is driven the wiper by the motor, and under the less condition of goggles overall structure, the space that sets up the motor is limited, has increased the weight of goggles to a certain extent to lead to user's discomfort. The utility model discloses a goggles adopts the cooperation of first defogging brush 300 and second defogging brush 400 to use, and appeal between the make full use of magnet, second defogging brush 400 drive first defogging brush 300, under high risk environment such as virus, poisonous and harmful gas, with the steam that hand swing second defogging brush 400 just can detach the goggles internal surface, guaranteed the goggles relatively inclosed space, reduce the risk of infecting the virus effectively, use safe and reliable more.

It should be emphasized that the iron core cannot be replaced by magnetic materials because no matter the magnetic poles exist in the soft magnetic strip or other magnetic materials, in the actual use process, when the second defogging brush acts, the magnetic poles of the magnetic materials on the two sides are easily opposite and mutually repulsive, so that the first defogging brush is twisted or turned on one side, and further the defogging function cannot be achieved. The utility model discloses a cooperation of iron core and soft magnetic strip for there is suction between the two inseparabler, can realize moving thereupon, and the defogging effect is best. In addition, the first defogging brush and the second defogging brush can exchange material structures, and can remove water mist as well.

In fig. 3 and 8, the rotating shaft 500 is a tapered body, a first through hole 340 is disposed at one end of the first defogging brush 300, a second through hole 430 is disposed at one end of the second defogging brush 400, and the first defogging brush 300 and the second defogging brush 400 are matched with the rotating shaft 500, and rotate around the rotating shaft. Due to the structure of the push-pull body, the first defogging brush 300 and the second defogging brush 400 are not easy to fall off and can be replaced when rotating.

Further, the soft magnetic strip 410 is similar to the soft magnetic strip 410 at the edge of the refrigerator door, the softness of the soft magnetic strip is completely adapted to the curvature of the mirror surface, and the width of the soft magnetic strip 410 is 2-3mm and is purchased from the market.

The goggles cover is covered on the face of a user, particularly in summer or under the condition of high temperature or for a long time, the water vapor inside the goggles is excessive, the water scraped by the first defogging brush 300 can be accumulated on the lower surface inside the goggles frame 100, and therefore, a water absorption part (not marked in the figure) can be detachably arranged on the lower surface inside the goggles frame 100 and can be a drying agent or absorbent cotton. Preferably, the water absorbing component is an OB tampon or a medical tampon or a sponge. When the water absorption capacity is larger, OB cotton slivers or medical absorbent cotton slivers or sponge slivers are replaced as much as possible, and in addition, drying agents are purchased in the market.

The first plastic soft framework 310 inside the first defogging brush 300 extends to the edge of the glasses frame, the iron core 320 is discontinuously distributed in the first plastic soft framework 310, the length of the relative cotton sliver 330 is larger than that of the first plastic soft framework 310, the water vapor at the edge of the lens 200 can be guaranteed to be completely removed, the first defogging brush 300 is moved under the action of magnetic force by the second defogging brush 400, and the length of the second defogging brush 400 can be slightly smaller than that of the first defogging brush 300.

In addition, the fixing band 600 of the goggles comprises a connecting buckle 610, a head band 620 and a locking buckle 630, wherein the connecting buckle 610 is fixedly connected with the protective glasses frame 100, and the head band 620 passes through the connecting buckle 610 and is locked through the locking buckle 630, so that the use is more convenient.

Example 2

The structure of this embodiment is substantially the same as that of embodiment 1, except that, as shown in fig. 9, fixing buttons 210 are provided at both sides of the lens 200, and the free end of the second defogging brush 400 is placed on the fixing buttons 210. Considering that the lens 200 is made of resin, the protection fixing button 210 is fixed on both sides of the lens 200 by adhesion, and the fixing button 210 may have magnetism or elasticity, so that the second defogging brush 400 may be fixed by suction or fastening force.

When not using, the free end of second defogging brush 400 can freely swing, and fixed button 210 has magnetism, can inhale mutually with the magnetic stripe 420 of second defogging brush 400, perhaps direct block, and on the other hand, second defogging brush 400 and first defogging brush 300 inter attraction, second defogging brush 400 is fixed through the power of two directions, avoids the swing of second defogging brush 400 effectively, reduces the influence to user's sight, uses more reliable and more stable.

Example 3

The structure of this embodiment is substantially the same as that of embodiment 1, except that the external fixing button 210 of the device for removing water mist in underwater operation does not adopt the magnetic fixing button 210 due to the action of water force, and the lock catch type fixing button 210 is adopted to eliminate the influence of water impact.

The utility model discloses an antifog gas goggles not only can be used for medical personnel's worker, equally if the diver takes place the condition that goggles or sight glass are covered by steam at the dive in-process, can bring unnecessary danger and trouble for diving.
