A kind of anti-fog swimming goggles based on the principle of thermoelectric power generation

Abstract

The invention belongs to the field of swimming equipment, and in particular relates to an anti-fog swimming goggle based on the principle of thermoelectric power generation, including a frame and a lens embedded in the frame, and a ceramic temperature difference sheet is fixedly embedded in the frame, and the ceramic temperature difference sheet The electrodes at both ends of the ceramic temperature difference plate are respectively located on the inner and outer sides of the lens, and the electrodes at both ends of the ceramic temperature difference sheet are respectively electrically connected to a plurality of positive and negative leads, and both the positive and negative leads extend to the inner surface of the lens, and Equidistant staggered parallel arrangement, the side walls on both sides of the frame are fixed with vibration box, the side wall of the vibration box facing the water flow side is composed of tympanum plate, the side wall of the vibration box is installed with a tuning fork rod , the vibration frequency of the tuning fork rod is consistent with that of the tympanic membrane. The invention can make the water droplets on the inner side of the mirror undergo two physical reactions of heat evaporation and electrolysis of water at the same time, and quickly disappear completely, which has a good anti-fog and water-removing effect, and avoids affecting the sight of swimmers.

Description

technical field

[0001] The invention belongs to the field of swimming equipment, in particular to an anti-fog swimming goggle based on the principle of thermoelectric power generation. Background technique

[0002] Swimming goggles are essential protective equipment for swimming. They can be attached to the eyes of swimmers to prevent swimming pool water from entering the glasses, so that swimmers can remain visible underwater, which not only increases the fun of swimming, but also Played the role of security protection.

[0003] However, most of the traditional swimming goggles have the problem of lens fogging and blocking the sight of swimmers when they are in use. When the hot gas contacts the swimming goggles, it will condense and fog up, which will affect the normal swimming movement. It is very troublesome to take off the swimming goggles to wipe the water mist from time to time. However, the anti-fog effect of the anti-fog coating will be greatly reduced after repea...

Examples

Embodiment 1

[0019] Such as Figure 1-2 As shown, a kind of anti-fog swimming goggles based on the principle of thermoelectric power generation, including a frame 1 and a lens 2 embedded in the frame 1, a ceramic temperature difference sheet 3 is fixedly embedded in the frame 1, and the electrodes at both ends of the ceramic temperature difference sheet 3 are respectively Located on the inner and outer sides of the lens 2, the electrodes at both ends of the ceramic temperature difference sheet 3 are electrically connected to a plurality of positive wires 4 and negative wires 5, both of which are made of indium tin oxide. The transparent conductive material does not affect the swimmer's normal line of sight. Both the positive lead wire 4 and the negative lead wire 5 extend to the inner surface of the lens 2 and are arranged in parallel at equal intervals. The side walls on both sides of the frame 1 are fixedly equipped with vibration boxes. 6. The side wall of the vibration box 6 facing the...

Embodiment 2

[0023] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a friction sheet 9 is attached to the inner wall of the mirror frame 1, and the friction sheet 9 is not fixed in contact with the positive lead wire 4 and the negative lead lead 5, and the positive lead wire 4 and the negative lead wire The outer surface of the wire 5 is coated with a wear-resistant coating at the position of the friction plate 9 .

[0024] In this embodiment, when the positive electrode lead 4 and the negative electrode lead 5 vibrate under the traction of the tuning fork rod 8, they rub against the friction plate 9 repeatedly, thereby generating heat, which is conducted to the surface of the lens 2 through the positive electrode lead 4 and the negative electrode lead 5, Speed ​​up the evaporation rate of water droplets.
