Description
Technical field
The utility model relates to a kind of teaching equipment, relates in particular to a kind of remote-controlled blackboard eraser.
Background technology
Chalk is as the instrument of transmission of culture in the modern teaching activity; Still in most education activities, use; But the dust that chalk produces after wiping is dispersed in the air, in Faculty and Students' inspiration lung, is easy to suffer from various breathing problems; Also can cause lung cancer etc. when serious, have a strong impact on the healthy of teachers and students.And existing wiping blackboard structure is simpler, after education activities finish, also need be with the blackboard wiped clean, and labor muscle power.
The utility model content
The utility model technical problem to be solved provides a kind of remote-controlled blackboard eraser of avoiding dust from flying and saving muscle power.
The purpose of the utility model mainly is achieved through following proposal: a kind of remote-controlled blackboard eraser; Comprise plate body, the wiping side of said plate body is provided with rotating brush, and the rear side of plate body is provided with dustbin; Be provided with the transmission device that makes the rotating brush rotation in the said plate body; Described rotating brush one side is provided with suction port, and described suction port links to each other through the logical dustbin of conduit of blower fan, is outside equipped with receiver of remote-control sytem, remote control transmitter in the described plate body; Also be provided with the trundle that plate body is moved on the described plate body, described receiver of remote-control sytem, drive mechanism are electrically connected with the power supply of control trundle.
Adopt the utility model, rotating brush is set, in the plate body when rotating brush rotates; The powder of chalk handwriting on the blackboard is brushed down; Suction port in the plate body is drawn into dust in the dustbin simultaneously, and the dust that timely chalk is produced is rapidly removed, and has avoided dust from flying.Inside and outside the plate body receiver of remote-control sytem and remote control transmitter are set simultaneously; So just can control moving of blackboard eraser through remote control transmitter; Therefore use the utility model; Not only saved muscle power, can also keep clear of blackboard and just can the blackboard wiped clean be helped the healthy of blackboard eraser user more.
As preferably, on the described rotating brush rotating shaft is set, said transmission device comprises electric rotating machine and belt, and described belt one end is enclosed within on the output shaft of electric rotating machine, and the other end is enclosed within the rotating shaft.Belt one end is enclosed within on the output shaft of electric rotating machine, and the other end is enclosed within the rotating shaft, just can be through the chalk writing on the rotating shaft driven rotary brush blackboard wiping, with the blackboard wiped clean when motor rotates like this.
As preferably, described remote control transmitter comprises button, stop key and time set key up and down.Utilize up and down button can control plate body and move up and down, can also control plate body simultaneously and stop and in setting-up time, working.
As preferably, described dustbin is provided with sewage draining exit.When the rubbish in the dustbin is filled, can the dust easy cleaning be fallen through sewage draining exit.
In a word, the beneficial effect of the utility model is: do not have dust from flying during blackboard wiping, and save muscle power, do not need just can the blackboard wiped clean be helped the healthy of blackboard eraser user more near blackboard.
