Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 5 and give, including axial and the decurrent headgear 1 of opening from top to bottom, the 1 front side of headgear is equipped with the fixed frame 2 of left right direction, be equipped with lens 3 in the fixed frame 2, be equipped with breather valve 4 on the lens 3, the sliding tray 5 of direction about having seted up on the fixed frame 2 left side wall, the upper and lower both sides of sliding tray 5 are equipped with push rod 6 respectively, two push rod 6 can be relative or move on the back mutually, the looks remote site of two push rod 6 is equipped with friction pad 7 respectively, the preceding terminal surface of friction pad 7 and the rear surface contact of lens 3, both ends are equipped with fixed band 8 respectively about fixed frame.

In order to enable the two push rods 6 to move oppositely or oppositely, the sliding groove 5 is connected with a screw rod 9 in an up-down axial direction in a rotating mode, the screw rod 9 is connected with the push rods 6 in a threaded mode, and the thread rotating directions of the upper side and the lower side of the screw rod 9 are opposite.

In order to rotate the screw 9, a moving groove 10 which is opened forwards in the left-right direction is formed on the fixed frame 2, a pull rope 11 which is positioned in the moving groove 10 is arranged on the screw 9, and a slide block 12 which is connected with the moving groove 10 in a sliding mode is arranged at the free end of the pull rope 11.

In order to reset the screw 9, a placing groove 13 coaxial with the screw 9 is formed in the fixing frame 2, a coil spring 14 is coaxially arranged in the placing groove 13, and the free end of the coil spring 14 is fixedly connected with the screw 9.

In order to improve the comfort of the user, the rear surface of the fixing frame 2 is provided with a latex pad 15, and the rear surface of the latex pad 15 is an arc surface which is axially and inwards concave.

In order to fix the device conveniently, the opposite surfaces of the two fixing bands 8 are respectively provided with a magic tape 16, and the two magic tapes 16 can be mutually bonded.

When the utility model is used, the device is taken out, the head cover 1 is worn on the head, the two fixed free ends are pulled, and after the rear surface of the rubber mat is contacted with the face of a user, the two magic tapes 16 are bonded to fix the device on the head of the user;

a user can breathe through the breather valve 4, and the breather valve 4 can filter air inhaled by the user, so that viruses are prevented from entering the body of the user through a respiratory tract;

when water mist appears on the lens 3, the sliding block 12 is pulled rightwards, the sliding block 12 drives the screw rod 9 to rotate clockwise through the pull rope 11, the screw rod 9 drives the coil spring 14 to contract, meanwhile, due to the fact that the thread turning directions of the upper side and the lower side of the screw rod 9 are opposite, the screw rod 9 drives the two push rods 6 to move relatively, the two friction pads 7 synchronously move relatively, and the friction pads 7 wipe the water mist on the lens 3;

when the two friction pads 7 are contacted, the two push rods 6 stop moving relatively, the sliding block 12 is loosened, the screw rod 9 rotates anticlockwise under the action of the coil spring 14, the screw rod 9 drives the sliding block 12 to move leftwards through the pull rope 11, meanwhile, the screw rod 9 drives the two friction pads 7 to move back and forth through the push rods 6, and the friction pads 7 wipe the lens 3 again;

when the opposite ends of the two push rods 6 are respectively contacted with the sliding groove 5, the push rods 6 stop moving, the screw rods 9 stop rotating, at the moment, the water mist on the inner surface of the lens 3 is wiped completely, if the water mist appears on the inner surface of the lens 3 again, the above operation can be repeated, and the water mist on the inner surface of the lens 3 is continuously wiped.

The breather valve 4 of the present invention is prior art and is not described in detail herein.
