Technical Field

The invention relates to the technical field of teaching aids, in particular to an electric cleaning blackboard eraser capable of adsorbing dust through static electricity.

Background

In modern teaching, most of teaching involve that the chalk writes characters or the pattern is convenient for explain, for the secondary is write, need erase the writing originally, because traditional blackboard eraser is formed by rag or cotton fabric, traditional mode is erased and can be taken out and erase unclean and the phenomenon that the classroom was flown full of dust. The dust has strong adsorbability, which brings many adverse effects. This can have respiratory health effects on teachers working for a long time and students in class. Nowadays, the number of people who educate about respiratory tract infection or other diseases caused by dust entering the lung is increasing day by day. So far, the substitute of chalk is not widely popularized, and most classrooms in regions are chalk containing calcium carbide. The health of older educators is seriously threatened in the long-term education industry. The dust problem can be treated by the existing feasible method, and in order to overcome the existing problems, a method which is convenient to clean and treat dust is devised.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides an electric cleaning blackboard eraser capable of adsorbing dust by static electricity, which can effectively collect dust, prevent the dust after erasing from flying, prevent environmental pollution and clean a bumpy blackboard.

The technical scheme is as follows: the invention provides an electric cleaning blackboard eraser capable of electrostatically adsorbing dust, which comprises a base, a shell, a storage box, an electrostatic adsorption assembly and a cleaning adsorption roller assembly, wherein the shell is arranged on the base; the outer surface of the roller is wrapped with a brush, and the lower surface of the brush is positioned below the bottom surface of the base; the storage box is arranged in the shell and positioned between the shell and the base, and a dust inlet is formed in the position, facing the roller, of the bottom of the storage box; the electrostatic adsorption component is arranged in the storage box.

Furthermore, the cleaning and adsorbing roller assembly comprises at least one roller coaxially fixed on the outer wall of the conductor shaft, the roller is rotatably connected with the bottom surface of the base through the conductor shaft, one end of the conductor shaft is fixedly connected with an output shaft of the motor and is conducted with the anode of a power supply, and the cathode of the power supply is conducted with the conductor rod; a plurality of conductor filaments are fixed in the hairbrush at intervals along the circumference of the outer wall of the roller, one end of each conductor filament is in effective contact with the conductor shaft, and when the roller rotates, the other end of each conductor filament can be in effective contact with the conductor rod at a certain moment; the motor, the power supply and the conductor bar are all fixed on the base. After a main switch of a power supply is turned on, a motor is started and drives a conductor shaft to rotate, the rotation of the conductor shaft drives a roller and a brush on the outer wall of the roller to efficiently rotate, and one surface of the blackboard eraser with the brush is in contact with a blackboard, so that chalk characters written on the blackboard can be erased; when the rotation of the roller drives the conductor filament to rotate to be in contact with the conductor rod, a loop is formed among the conductor shaft, the power supply, the conductor rod and the conductor filament, an electrostatic effect is generated in the brush, the erased dust is adsorbed to the brush, and after the roller continues to rotate to drive the conductor filament to be separated from the conductor rod, the loop is disconnected, the electrostatic effect disappears, and the brush loses the adsorption force on the dust.

Preferably, the cleaning and adsorbing roller assembly comprises two rollers, the two rollers are parallel to each other, and each roller is parallel to the corresponding conductor bar.

Preferably, each of said conductor filaments is arranged perpendicular to said conductor axis.

Preferably, the spacing between the conductor axis and the conductor bar is less than the length of the conductor filament. This design ensures that the conductor filament can be in contact with the conductor bar at a certain moment during rotation.

Further, the electrostatic adsorption component comprises a positive copper sheet, a negative copper sheet, a positive and negative interface female head and a positive and negative interface male head, wherein the positive and negative interface male head is fixed on the base and communicated with the positive and negative electrodes of the power supply, the positive and negative interface female head is fixed in the storage box and communicated with the positive and negative interface male head in an inserting and inserting manner, and the positive copper sheet and the negative copper sheet are respectively communicated with the positive electrode and the negative electrode of the positive and negative interface female head through leads. In the electrostatic adsorption component in the storage box, after the male heads of the positive and negative interfaces are inserted and matched with the female heads of the positive and negative interfaces to be conducted, a circuit formed by the positive copper sheet, the negative copper sheet, the female heads of the positive and negative interfaces and the male heads of the positive and negative interfaces is conducted, the electrostatic adsorption component can continuously generate an electrostatic effect, and the electrostatic effect can adsorb dust on the brush into the storage box through the dust inlet.

Preferably, the base and the shell are detachably mounted through a buckle. Due to the detachable installation, the base and the shell are convenient to detach, and the internal structure of the blackboard eraser is convenient to maintain.

Furthermore, the shell is provided with a window for loading or taking out the storage box. The window is provided so that the storage case can be easily taken out of or put into the case.

Has the advantages that: the blackboard eraser can electrically brush off dust on the blackboard through the cleaning and adsorbing roller assembly, the dust is adsorbed on the hairbrush, and then the dust on the hairbrush is adsorbed in the storage box through the dust inlet by the electrostatic adsorption assembly in the storage box. This blackboard eraser can be directly with the dust after erasing adsorb on the brush and adsorb in the storage box, directly invert the blackboard eraser after finishing using, then the outage, the dust in the storage box loses the absorption of electrostatic absorption subassembly and can fall in the storage box, then takes out the storage box through the window of casing, it can to fall the dust.

Therefore, the blackboard eraser can effectively collect dust, prevent the dust after erasing from flying, prevent environmental pollution and protect the health of teachers and students. In addition, due to the existence of the brush on the outer surface of the roller in the cleaning and adsorbing roller assembly, the blackboard eraser can clean a hollow and uneven blackboard, and the blackboard is more effectively cleaned.
