Abstract
The utility model discloses a kind of glasses that prevented fog.Comprise picture frame, eyeglass and mirror leg, wherein in picture frame and be positioned on the circumference of eyeglass heating wire is installed, the inside of picture frame and be positioned at the bridge of the nose thermistor is partly installed, mirror leg inside is provided with switch and electrothermal wire heating's battery is provided.The utility model effectively solves the difference of environment temperature and lens temperature and the eyeglass that causes plays the problem of fog; And whole process does not need manual control, simple in structure, feasibility is high.
Description
technical field:
The utility model belongs to a kind of glasses, is specially a kind of glasses that prevented fog.
background technology:
In winter, people come into warm room from cold outdoor, and glasses can play fog; Eat of hot thing, glasses also can blur; Wear glasses simultaneously and go out with mouth mask, glasses play fog and easily fall especially.Make like this user's of wearing spectacles needs polishing one's glasses frequently, can bring very large wearing and tearing to glasses, and bring very large inconvenience to the user of frequent wearing spectacles.
Therefore, the necessary deficiency of prior art being improved to solve prior art.
summary of the invention:
The utility model has prevented that the Glasses structure of fog is simple, has effectively prevented that lens from hazing, and makes people with glasses's vision good.
The technical scheme that the utility model adopts has:
A kind of glasses that prevented fog, comprise picture frame, eyeglass and mirror leg, in picture frame and be positioned on the circumference of eyeglass heating wire is installed, the inside of picture frame and be positioned at the bridge of the nose thermistor is partly installed, mirror leg inside is provided with switch and electrothermal wire heating's battery is provided.
Further, heating wire, thermistor, battery and switch are by wire composition control circuit, and wire is arranged on the inside of picture frame and mirror leg.
Further, picture frame and mirror leg adopt the two halves of buckle-type.
Further, picture frame and mirror leg adopt adiabatic plastics.
The utlity model has following beneficial effect:
(1) the utility model is simple in structure, effectively solves the problem that the eyeglass causing higher than lens temperature because of environment temperature plays fog, and whole process does not need manual control, feasibility high.
(2) picture frame of the present utility model and mirror leg be can section the two halves of dismounting, heater element is arranged on the inside of glasses, designs ingeniously, does not affect the outward appearance of glasses, what make that wearer wears is more comfortable.
accompanying drawing explanation:
Fig. 1 is the structural drawing that the utility model has prevented the glasses of fog.
Fig. 2 is the interior circuit diagram of glasses that the utility model has prevented fog.
Wherein
1, picture frame; 2, eyeglass; 3, mirror leg.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1 and Fig. 2, the utility model has prevented the glasses of fog, comprise picture frame 1, eyeglass 2 and mirror leg 3, wherein in picture frame 1 and be positioned on the circumference of eyeglass 2 heating wire is installed, the inside of picture frame 1 and be positioned at the bridge of the nose thermistor is partly installed, mirror leg 3 inside are provided with the switch that electrothermal wire heating's battery is provided and controls battery power on/off, and battery adopts AG3 button cell.Wherein battery, heating wire, thermistor and switch form a control circuit by wire.Picture frame 1 and mirror leg 3 be can section the two halves of dismounting, picture frame 1 and mirror leg 3 are adiabatic plastics.Because the typical feature of thermistor is to responsive to temperature, and thermistor is fairly obvious with the raise linear relationship that reduces of temperature.Therefore,, when ambient temperature is during higher than eyeglass 2 temperature, thermistor resistance diminishes, according to Ohm law: U=IR, in circuit, electric current increases, and according to Joule law Q=I2RT, the heat that heating wire produces uprises, eyeglass 2 is heated, and eyeglass 2 diminishes with the temperature difference of environment, so eyeglass 2 just can not play fog.And when continuous heating is after a period of time, the temperature of glasses uprises, it is large that the resistance of thermistor becomes. in like manner, according to Ohm law, the electric current in circuit becomes very little, and circuit is similar to and opens circuit, and heating wire just stops heating.
The above is only preferred implementation of the present utility model, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
