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
The present invention relates to a kind of Eraser Tool, particularly a kind of electric heating erasing rubber.
Background technology
The ball pen that existing a kind of writing can disappear, its characteristic are that the writing write can disappear after temperature surpasses 60 ℃, and writing can reappear when being lower than-30 ℃ in temperature, and the benefit of this ball pen is to write the back writing to be easy to wipe, and conveniently revises.Existing this ball pen is to be provided with block rubber on the penholder top, thereby utilizes rubber bumper frictional heat on paper to wipe writing.But this operating process need wiping repeatedly on paper, troublesome poeration, and wrinkle easily or do broken and open.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of electric heating erasing rubber that can not wrinkle paper.
The technical scheme that the present invention adopted mainly is:
A kind of electric heating erasing rubber comprises power module, heating resistor, and said power module is a battery, is provided with gauge tap between said power module and the heating resistor, and said gauge tap is two press buttones that are connected in series with heating resistor.
As the further improvement of technique scheme, said heating resistor is the PTC thermistor.The PTC thermistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, and during when PTC resistance conducting heating and above Curie temperature, its resistance value can be increasing of step evolution along with the rising of temperature, makes it no longer continue to heat up, and uses safer.
As the further improvement of technique scheme, can recycle for the battery that makes the design, said battery is a rechargeable battery.Further, said rechargeable battery also is connected with the USB charging module, and is easy to connect.
The invention has the beneficial effects as follows: this electric heating erasing rubber is pressed the work of just can generating heat of two press buttones at the same time, effectively avoids occurring the situation of error starting; When pressing two press buttones simultaneously, the heating resistor heating power, its temperature rises to 80 ~ 120 ℃, from the person's handwriting of ball pen, smears the heating resistor of electric heating erasing rubber gently, and person's handwriting is disappeared, and is simple to operate, and can not wrinkle paper.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is circuit theory diagrams of the present invention.
The specific embodiment
With reference to Fig. 1; A kind of electric heating erasing rubber provided by the invention comprises power module 1, heating resistor 2, and said power module 1 is a battery; Said battery is a rechargeable battery; Said rechargeable battery is connected with the USB charging module, is provided with gauge tap 3 between said power module 1 and the heating resistor 2, and said gauge tap 3 is two press buttones 4,5 that are connected in series with heating resistor 2.
Preferably, said heating resistor 2 adopts the PTC thermistor.
During use, press two press buttones 4,5 simultaneously, heating resistor 2 heating powers, its temperature rises to 80 ~ 120 ℃, from the person's handwriting of ball pen, smears the heating resistor 2 of electric heating erasing rubber gently, and person's handwriting is disappeared, and is simple to operate, and can not wrinkle paper.
The above is merely preferential embodiment of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
