Embodiment Construction

[0011] refer to figure 1 , a kind of electric heating eraser provided by the present invention comprises a power supply module 1 and a heating resistor 2, the power supply module 1 is a battery, the battery is a rechargeable battery, the rechargeable battery is connected with a USB charging module, and the power supply module 1 A control switch 3 is arranged between the heating resistor 2 and the control switch 3 is two push button switches 4 and 5 connected in series with the heating resistor 2 .

[0012] Preferably, the heating resistor 2 is a PTC thermistor.

[0013] When in use, press the two button switches 4 and 5 at the same time, the heating resistor 2 will be energized to generate heat, and its temperature will rise to 80~120°C. Gently wipe the heating resistor 2 of the electric eraser over the handwriting of the ballpoint pen to make the handwriting Disappears, easy to operate, and won't crease paper.

[0014] The above descriptions are only the preferred implement...

Abstract

The invention discloses an electric heating eraser which comprises a power module and a heating resistor. The power module is a battery, a control switch is arranged between the power module and the heating resistor and comprises two button switches which are connected in series, after the two button switches are pressed down simultaneously, the electric heating eraser begins to heat and work, and mistaken start is avoided effectively; and when the two button switches are pressed down simultaneously, the heating resistor is powered on and heated, the temperature of the heating resistor rises to 80-120 DEG C, handwriting of a ball-point pen can disappear by slightly wiping the heating resistor of the electric heating eraser on the handwriting of the ball-point pen, the electric heating eraser is simple in operation, and paper cannot be creased.

Description

technical field [0001] The invention relates to an eraser tool, in particular to an electric heating eraser. Background technique [0002] There is an existing ballpoint pen whose writing will disappear. Its characteristic is that the written writing will disappear when the temperature exceeds 60°C, and the writing will reappear when the temperature is lower than -30°C. The advantage of this ballpoint pen is that the writing is easy to erase after writing. to facilitate corrections. The existing ballpoint pen is provided with a rubber block at the top of the pen holder, and the rubber block is used to rub against the paper to generate heat so as to wipe off the handwriting. However, this operation process requires repeated wiping on the paper, which is cumbersome to operate, and it is easy to wrinkle or damage the paper. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide an electr...
