Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a graphene leg warmer. Background Art

[0002] In the cold winter, even if wearing thick and warm shoes and socks, due to the long-term sitting causing poor blood circulation, the legs will still be cold, which makes leg warmers more and more popular. Graphene materials have high thermal conductivity. According to the principle of resonance, they can release far-infrared light waves similar to those of the human body. When working, they can emit heat similar to sunlight. When the graphene far-infrared rays contact the human body, their temperature is more easily accepted, which can promote human blood circulation and metabolism and enhance human resistance.

The graphene leg warmer, first insert the charging plug into the socket to power on, control the graphene heating film to heat up by adjusting the switch, the graphene heating film is powered on and radiates far infrared rays, the flexible protective layer absorbs far infrared rays and heats up and transfers the heat, the flexible protective layer, the graphene heating film and the annular anti-slip sleeve are flexible materials, which can be adjusted to a desired shape, when the legs need to be heated, the flexible protective layer needs to be adjusted to a cylindrical shape, when the first mounting frame and the second mounting frame are installed and combined, the first mounting frame drives the plug plate to be inserted into the slot cavity to make the flexible protective layer cylindrical, the installation is convenient and quick, the legs are inserted into the cylindrical flexible protective layer, the flexible fabric cover is installed through a zipper, and the spring hook is adjusted to be hooked on the required adjustment belt to achieve the distance between the flexible fabric cover and the legs to prevent heat loss.

[0018] 2. For the graphene leg warmer, when the first mounting frame and the second mounting frame are combined, the moving block and the second mounting frame abut against each other, and the moving block moves toward the inside of the first mounting frame. As the sliding column slides along the guide groove, the sliding column pulls the block plate into the first mounting frame, thereby releasing the restriction of the sliding rod by the block plate, and the pushing spring pushes the pushing plate to move, and the pushing plate drives the support plate to contact the ground through the fixed rod, thereby preventing the cylindrical flexible protective layer from tilting and causing heat loss, which affects the use effect of the device.

[0019] 3. When the graphene leg warmer needs to be rolled up after use, the plug plate will first be separated from the slot cavity. Since the moving block does not abut against the second mounting frame, the reset spring pulls the moving block to reset, thereby moving the slide column through the guide groove, and the block plate moves out of the first mounting frame, and then the support plate is folded into the protective support frame. The support plate pushes the push plate and the slide rod to move, and the slide rod slides in the slide groove. When the slide rod pushes the slope surface of the block plate, the block plate moves into the first mounting frame. When it contacts the straight surface of the block plate, the block plate restricts the slide rod to prevent the slide rod from moving, so that the support plate is stored in the protective support frame for easy storage and carrying.

[0037] In summary, the working principle of a graphene leg warmer according to an embodiment of the present invention is as follows: First, insert the charging plug 205 into a socket to power on. Control the graphene heating film 102 to generate heat through the adjustment switch member 203. The graphene heating film 102 is powered on and radiates far-infrared rays. The flexible protective layer 101 absorbs the far-infrared rays, heats up, and transfers the heat. The flexible protective layer 101, the graphene heating film 102, and the annular anti-slip sleeve 103 are made of flexible materials, so that they can be adjusted into the required shape. When the leg needs to be heated, the flexible protective layer 101 needs to be adjusted into a cylindrical shape. When the first mounting bracket 201 and the second mounting bracket 202 are installed and combined, the first mounting bracket 201 drives the plug board 21 to insert into the slot cavity 22, so that the flexible protective layer 101 becomes cylindrical, which is convenient and fast to install. Insert the leg into the cylindrical flexible protective layer 101, install the flexible cloth cover 105 through the zipper 104, and hook it on the required adjustment belt 303 through the adjustment spring hook 302 to realize the distance between the flexible cloth cover 105 and the leg and prevent heat loss.

[0038] After the first mounting bracket 201 and the second mounting bracket 202 are combined, the moving block 502 abuts against the second mounting bracket 202, and the moving block 502 moves towards the inside of the first mounting bracket 201. Since the sliding column 504 slides along the guiding groove 503, the sliding column 504 pulls the clamping plate 505 into the first mounting bracket 201, so that the clamping plate 505 releases the restriction on the sliding rod 406. The pushing spring 408 pushes the push plate 405 to move. The push plate 405 drives the support plate 403 to contact the ground through the fixing rod 404, preventing the cylindrical flexible protective layer 101 from tilting and causing heat loss, which affects the use effect of the device.

[0039] When the device needs to be wound up after use, first, the plug board 21 is disengaged from the slot cavity 22. Since the moving block 502 does not abut against the second mounting bracket 202, the return spring 501 pulls the moving block 502 to reset, thereby moving the sliding column 504 through the guiding groove 503, and the block plate 505 moves outward from the first mounting bracket 201. Then, the support plate 403 is folded into the protective support frame 401. The support plate 403 pushes the push pressure plate 405 and the sliding rod 406 to move. The sliding rod 406 slides in the sliding groove 407. When the sliding rod 406 pushes the ramp surface of the block plate 505, the block plate 505 moves into the first mounting bracket 201. When it contacts the straight surface of the block plate 505, the block plate 505 restricts the sliding rod 406 to prevent the sliding rod 406 from moving, so that the support plate 403 is received into the protective support frame 401, facilitating storage and carrying.

[0040] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
