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 eraser of the present invention needs to complete functions such as electric dust removal, dust storage, and internal energy automatic management, and mainly includes four parts: a power generation unit, an electric unit, an energy management unit, and a detection and indication unit.

[0102]Power generation unit: When the user wipes the blackboard, the horizontal movement of mechanical friction between the blackboard eraser and the blackboard is converted into the rotational movement of the outer rotor permanent magnet generator rotor through the raised particles, and a rotating magnetic field is generated in the motor, resulting in its static stator The winding is cut by the magnetic field to generate an AC induced electromotive force. When the load is connected externally, it provides electric energy to the load (such as figure 1 shown).

[0103] Electric unit: through the controlled permanent magnet brushless DC motor, the electr...

Abstract

The invention belongs to the technical field of cleaning devices for blackboards or stone slabs, and discloses an intelligent electric blackboard eraser, a control system and a control method thereof. The intelligent electric blackboard eraser control system comprises a power generation unit, an electric unit, an energy control unit and a detection indicator unit, wherein voltage after power generation and rectification, battery voltage, generator rotor speed and dust capacity in a dust storage box are detected, and meanwhile, a current operating state is indicted through a light-emitting diode (LED) light. According to the intelligent electric blackboard eraser, the control system and the control method thereof provided by the invention, a dust wiping method of traditional mechanical friction is abandoned, and a permanent magnet motor drives a dust collection fan to rotate at high speed, so that a space negative pressure is produced in a relatively sealed space, dust can be effectively sucked so as to be separated from a blackboard, the aims of reducing the manual labor intensity and improving a dust wiping effect are achieved, in addition, the effects on automatically storing the dust and being free of charging are achieved, the external energy supply is not needed, the convenience in use is improved, meanwhile, a dust collection state can be observed, and real-time processing can be carried out conveniently.

Description

technical field [0001] The invention belongs to the technical field of cleaning devices for blackboards or slates, and in particular relates to an intelligent electric blackboard eraser, a control system and a control method thereof. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] As an important teaching tool, the blackboard eraser can directly affect the quality of teaching and the teaching environment by wiping chalk writing and handling dust. Because the teaching site is relatively closed and the personnel are relatively concentrated, the dust is a great hazard to the health and safety of personnel. However, most of the traditional blackboard erasers do not handle the dust in place, and some improved blackboard erasers need manual maintenance on a regular basis, which is not convenient to use. [0004] Most of the traditional blackboard erasers only rely on manpower to wipe the dust by mechanica...
