It is connect with control mechanism to regulate and control the temperature of the clipboard.
Further, heating backplate, the heating backplate and writing are equipped between the clipboard and first heater
Plate fitting.
Further, the heating backplate is equipped with equally distributed diathermanous hole, and the shape in the diathermanous hole is round, water chestnut
Shape or square.
Further, the heating backplate is equipped with for detecting the temperature-detecting device for writing plate temperature, the temperature
Detection device is connect with control mechanism.
Further, the first heater includes heater element and overheat protector, and the heater element is for producing
Heat amount, the overheat protector are used to detect the temperature around heater element, if being more than preset temperature, cut off the power.
Further, the control mechanism includes first heater control switch and air-blower control switch.
Further, the Easy erasing blackboard further includes frame, the blackboard body, heating backplate, first heater and
Blower is successively fastened in frame.
Further, the Easy erasing blackboard is also configured with blackboard eraser, is provided with secondary heating mechanism in the blackboard eraser.
Further, the clipboard is the rtificial leather of heat-resistant fireproof, is conducive to flash heat transfer and heat dissipation.
Since the utility model uses above technical scheme, the beneficial effect for having the application is:
1, the utility model uses writing liquid to be write on clipboard for the lettering pen of the hot irreversible ink that disappears, and
First heater hot wind effect under, written contents can the transparent color of automatic classifying, without manual wipe.
2, the Easy erasing blackboard of the utility model is under the effect of blower cold wind, clipboard can fast quick-recovery room temperature, it is convenient again
It writes.
3, it is evenly distributed with diathermanous hole on the utility model heating backplate, blows convenient for hot wind or cold wind to clipboard, reaches
The purpose for quickly heating or radiating.
4, the Easy erasing blackboard of the utility model is also configured with blackboard eraser, is equipped with secondary heating mechanism in the blackboard eraser, just
In the wiping of local content.
