Problems solved by technology

[0006] Most of the traditional blackboard erasers do not properly handle the dust. Not only does it require a lot of manual labor, but also the dust wiping effect is not good, the efficiency is low, and it is not conducive to the absorption of dust. Some improved blackboard erasers require manual cleaning on a regular basis. Maintenance, and the internal battery needs to be manually replaced regularly or the power can be supplemented by an external charger, which is not convenient enough

Embodiment 1

[0101] The intelligent electric blackboard of the present invention needs to complete the electric discharge, dust, internal energy automatic management, etc., mainly including power generation units, electric units, energy management units, and detects four parts of the indication unit.

[0102]Power Generation unit: When the user wipes the blackboard, the mechanical friction horizontal movement between the blackboard and the blackboard is converted into the rotational movement of the outer rotor permanent magnet generator rotor, generating a rotating magnetic field in the motor, resulting in its stationary stator The winding is cut by a magnetic field, generating an alternating electromotive force, and when an external load is supplied, it is to provide electrical energy to the load (eg figure 1 Indicated).

[0103] Electric unit: Controlling the electrical energy into a rotary mechanical energy through a controlled permanent magnet brushless DC motor, and drive the coaxial vacu...

Abstract

The invention belongs to the technical field of blackboard or slate cleaning devices, and discloses an intelligent electric blackboard eraser, a control system and a control method thereof. The intelligent electric blackboard eraser control system includes a power generation unit, an electric unit, an energy control unit, and a detection and indication unit. The voltage after power generation and rectification, battery voltage, generator rotor speed, and the amount of dust in the dust storage box are detected, and the current operating status is indicated by LED lights. The invention abandons the traditional mechanical friction dust wiping method, and the permanent magnet motor drives the dust suction fan to rotate at high speed, thereby generating negative pressure in the relatively closed space, effectively absorbing the dust, and making the dust separate from the blackboard, so as to reduce the labor intensity, The purpose of enhancing the dust wiping effect, and also has the effect of automatic dust storage, no charging, no need for external energy supplementation, which improves the convenience of use, and at the same time, the dust collection status can be observed, which is convenient for timely processing.

Description

Technical field [0001] In particular, the invention belongs to the technical field of cleaning devices of blackboard or slate, in particular, to a smart electric blackboard erase, control system, and a control method thereof. Background technique [0002] At present, the existing technology in the industry is like this: [0003] Blackboard is wiped as an important teaching tool that directly affects the treatment of dust directly affects teaching quality and teaching environments. Due to the relatively close closure of the teaching venue, the personnel have a greater health and safety of people's health. The traditional blackboard is mostly in place, and some modified blackboard wipes require manual regular maintenance, not convenient to use. [0004] Traditional blackboard wipes only with manpower to wipe dust in a mechanical friction, so that it is separated from the blackboard, due to poor controllability, not only is the dusty effect, low efficiency is not conducive to the ab...
