Reciprocating type electric eraser

Abstract

The invention discloses a reciprocating type electric eraser which comprises a shell, a reciprocating type motor and a battery. The reciprocating type motor is embedded in an inner cavity of the shell and is close to a working end, the battery is embedded in the inner cavity of the shell and is far away from the working end to provide a working power supply for the reciprocating type motor, and an eraser is clamped at the front end of a reciprocating type push rod at the front end of the reciprocating type motor. According to the reciprocating type electric eraser, the wiping mode that a high-speed rotating motor is matched with a cylindrical eraser and concentric high-speed rotation is adopted in a traditional electric eraser is changed into the reciprocating type wiping mode that the eraser is used by simulating a human hand, and safety is high.

Description

technical field [0001] The invention relates to the technical field of environmental sanitation equipment, in particular to a reciprocating electric rubber. Background technique [0002] The existing electric erasers all adopt a high-speed rotating motor with a cylindrical (mostly rubber core with a diameter of 2.5mm-8mm) rubber concentrically rotating structure, using the high-speed rotation of the motor to drive the rubber to generate friction, and the text, pictures, etc. that need to be modified After modification, this type of electric eraser does not have high requirements for the cleaning ability of the eraser itself, and it is completely wiped by the friction generated by high-speed rotation. This structure has the following obvious defects: 1) Because the contact area between the cylindrical rubber and the paper is small, in order to better achieve the cleaning effect, the average number of revolutions of the motor used is relatively large, and the friction force ge...

Problems solved by technology

This structure has the following obvious defects: 1) Because the contact area between the cylindrical rubber and the paper is small, in order to better achieve the cleaning effect, the average number of revolutions of the motor used is relatively large, and the friction force generated is relatively large. In the process of repeated wiping, it is easy to wear or fluff the paper, destroying the effect of the entire writing or painting; 2) Because the rubber is made of soft material, centrifugal force will be generated during high-speed rotation, and the rubber will swing greatly, making it difficult to control the modification 3) Although the motor has no leakage, the eraser will rotate with the motor at high speed, and there is still a certain danger, especially for school-age girl users, it is easy to stir long hair into it
