Description
Technical Field
The utility model relates to a stationery technical field, specific portable instrument that is used for erasing the thermal ink vestige specially that says so.
Background
At present, the application of thermal ink (such as erasable water pen and erasable white board pen) is wide. The erasable water pen and the whiteboard pen generate heat in a friction mode to erase wrong and unwanted traces. The process wastes time and labor, and has the defects of abrasion damage to paper and small erasing area. The invention can rapidly obtain the heat for erasing the trace of the thermal ink by electric heating, can efficiently erase the trace generated by the thermal ink and does not damage paper.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned prior art not enough, the utility model provides a portable instrument for erasing the thermal ink vestige specially. Through the electric heating mode, the defects that the existing friction mode wastes time and labor, can not erase in a large area and abrades paper are overcome.
The utility model provides a pair of portable instrument for erasing thermal ink vestige specially is realized through following technical scheme:
a portable tool specially used for erasing thermosensitive ink marks comprises a shell, wherein a storage battery is arranged in the shell, a heating element is fixedly installed on the shell, a switch is arranged on the shell, and the storage battery, the switch and the heating element are connected in series.
The number of the heating elements is 2, the heating elements are respectively fixed at two ends of the shell, and the length of one heating element is larger than that of the other heating element.
A battery jar is fixedly installed in the shell, and a storage battery is detachably installed in the battery jar.
The shell sets up to be the pen form, including nib and left shell, right shell, left shell, right shell pass through the screw fixation, and the screw thread of nib and left shell bottom is connected, can twist the screw when trading the battery, separates left shell, right shell.
The constant-value resistor is connected with the storage battery, the switch and the heating element in series and used for limiting the temperature of the heating element.
The utility model has the advantages that: through electric heating, labour saving and time saving reduces the wearing and tearing to the paper, erases efficiently.

Detailed Description
The technical solution of the present invention will be described clearly and completely by the following embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.
The portable tool specially used for erasing the thermal ink marks as shown in fig. 1-4 comprises a housing 1, a storage battery 2 is arranged in the housing, a first heating element 3 and a second heating element 4 are fixedly arranged at two ends of the housing respectively, a first switch 5 and a second switch 6 are arranged on the housing 1, the storage battery 2, the first switch 5 and the first heating element 3 are connected in series, and the storage battery 2, the second switch 6 and the second heating element 4 are connected in series. The first and second heat generating elements 3 and 4 may be heating wires coated with aluminum cases.
The second heating element 4 is longer than the first heating element 3 for erasing a larger area.
A battery jar 7 is fixedly installed in the shell 1, and a storage battery 2 is detachably installed in the battery jar 7.
The shell 1 is arranged to be pen-shaped and comprises a pen point 11, a left shell 12 and a right shell 13, the left shell 12 and the right shell 13 are fixed through screws, threads 121 at the bottoms of the pen point 11 and the left shell 12 are connected, the screws can be screwed off when the battery is replaced, and the battery can be taken out by separating the left shell and the right shell.
The constant value resistor 8 is further included, and the constant value resistor 8 is connected in series with the circuit shown in FIG. 4.
The utility model discloses using is, opening first switch 5 or second switch 6, the circuit switches on, and a little waiting for a moment, and first heating element 3 or second heating element 4 that correspond with it can generate heat, can erase the ink.
The above-described embodiments are merely illustrative of embodiments of the present invention, which are described in detail and detail, but are not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
