Abstract
The utility model relates to the technical field of heating equipment. In the existing electric heating hand warmer, signal lamps are respectively arranged in a shell, and due to high temperature of more than 100 DEG C, the signal lamps fails early and have shortened service life. The utility model provides an electric heating hand warmer with external signal lamps, consists of a hand warmer shell, the signal lamps, a current transformer and a power line, and is characterized in that the power line at any side connected with the shell of the hand warmer passes through the current transformer and is communicated with a power supply; and the current transformer is provided with the signal lamps of the electric heating hand warmer. When in use, when the hand warmer heats, current I1 flows through the power line, simultaneously current I2 is generated in the current transformer, and the signal lamps light on. When the heating of the hand warmer is finished, no current flows through the power line, and the signal lamps light off. The electric heating hand warmer has the benefits of prolonging the service life of signal lamps and having good effect.
Description
Technical field:
This utility model relates to a kind of heating equipment technical field.
Technical background:
Existing electric heating hand warmer, signal lights all is positioned in the housing, because the high temperature of last Baidu, premature failure often, the life-span shortens; Make troubles to user, not ideal.
Summary of the invention:
In order to overcome above-mentioned deficiency, this utility model provides a kind of signal lights external electric heating hand warmer.Just can reach the purpose that prolongs the signal lights life-span.
The technical scheme in the invention for solving the technical problem is: by the hand warmer housing, signal lights, current transformer, the external electric heating hand warmer of signal lights that power line is formed, it is characterized in that: any side power line linking to each other with the hand warmer housing, pass current transformer and be connected with power supply; The signal lights of electric heating hand warmer is set on current transformer in addition.During use, when hand warmer heated, power line had electric current I 1 to pass through, and produced electric current I 2 simultaneously in current transformer, and signal lights is bright.When hand warmer heating complete, the power line no current, signal lights puts out.
The beneficial effects of the utility model are: increase the signal lights life-span, and effective.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is this utility model structural representation.
1. hand warmer housings among the figure; 2. signal lights; 3. current transformer; 4. power line.
The specific embodiment:
Among Fig. 1, any side power line 4 linking to each other with hand warmer housing 1 passes current transformer 3 and is connected with power supply, and the signal lights 2 of electric heating hand warmer is set on current transformer in addition.During use, when hand warmer heated, power line had electric current I 1 to pass through, and produced electric current I 2 simultaneously in current transformer, and signal lights is bright.When hand warmer heating complete, the power line no current, signal lights puts out.
