Anti-fogging of dental mirror using PTC heater. It uses a PTC temperature sensor to generate a constant temperature and transfers the heat to the hot wire coating on the back of the mirror to raise the mirror surface to a constant temperature. It is designed to prevent fog caused by temperature differences.

Considering the fact that there is a lot of discomfort caused by the human heat on the mirror that enters the patient's mouth during dental treatment, the doctor feels a lot of inconveniences in the treatment, and thus the purpose is to create a more accurate and clear medical environment by preventing the mist on the mirror. have.

The present invention maintains the mirror surface temperature at a constant level by heat-coating the mirror behind the mirror with a minute current as a normal battery, and adopts a PTC temperature sensor to maintain a constant temperature. It is designed to be able to separate and detach the main body and the mirror by disinfection by using it, and it is configured to continue to use by charging and using normal battery or rechargeable battery.

In detail, the present invention is described with an example of the anti-fog mirror body 11, the detachable mirror 12, the body charging cradle 16, the present invention is composed of three anti-fog mirror body 11 Pushing the detachable mirror 12 into the mirror insertion holder 6; Rotating the mirror 12 by 90 degrees fixes the main body and the detachable mirror by the respective fixing clips 5; At this time, the main body heat transfer connection terminal 4 and the mirror heat transfer connection terminal 7 are completely connected to prepare for smooth heat transfer;

When the user turns on the ON / OFF switch 3 to use the mirror, the PTC heater 13 heats the PTC heater 13 by using the PTC temperature sensor circuit 2 to generate the current generated from the rechargeable battery 1 ; This heat is connected to the heat transfer connecting terminal 4 of the main body and the mirror heat transfer connecting terminal 7 through the heat transfer copper wire 14 inside the main body, thereby removing the copper wire 14 inside the split mirror 12. It transfers heat to the hot wire coating (8) on the back of the mirror (9). At this time, the temperature is kept warm enough to the human body.

When the user inserts the detachable mirror 12 into the medical antifogging mirror body 11 correctly and waits, the red wire lights up to indicate that the heating wire operation indicator 10 is in a standby state, and the user applies heat to the mirror for use. When the ON / OFF switch 3 is turned ON, heat is generated in the PTC heater 13. At this time, the operation indicator 10 lights up blue light to confirm that the heat is generated. .

In order to charge the power to the rechargeable battery (1) inside the medical anti-fogging mirror body 11, the main body 11 is plugged into the charging and charging cradle 16 to be charged.

When anti-fog mirror is used, it is possible to completely solve the problem of discomfort in oral observation due to the gimseorim that is always occurring when doctors examine the patient's oral cavity. Hygiene problems can also be solved.
