Abstract

The invention discloses a teaching blackboard with dust removal function, which comprises a blackboard bracket, a blackboard belt, a main belt roller, an auxiliary belt roller, an electric motor, a transmission belt, a negative pressure fan and a dust collector, and the main belt roller and the auxiliary belt are The rollers are installed horizontally on the bottom and the top of the blackboard support respectively, a blackboard belt is installed between the main belt roller and the auxiliary belt roller, one end of the main belt roller is connected with the output shaft of the electric motor, and the main belt roller is connected to the The auxiliary belt roller is connected through the transmission belt, the negative pressure fan is connected with the outlet end of the dust collector, and the inlet end of the dust collector is connected with the inside of the blackboard support through a connecting pipe. The teaching blackboard with dust removal function of the present invention improves the current traditional blackboard dust flying everywhere during the wiping process, greatly improves the indoor air, and realizes the function of combined push-pull blackboard, which is convenient for all students in the room. It is clearly visible and helps to improve the quality of teaching.

Description

【Technical field】 [0001] The invention relates to the technical field of teaching appliances, in particular to a teaching blackboard with dust removal function. 【Background technique】 [0002] The teaching blackboard does not specifically refer to the black writing board for teaching. In the traditional sense, it is a flat board that can be written repeatedly. At present, teaching blackboards are mainly flat blackboards, curved blackboards, bracket movable writing boards, lifting blackboards, and combined push-pull blackboards. However, these forms of blackboards have the problem of large dust content during the wiping process. It is impossible to remove dust in a timely and comprehensive way when using it, and it can only achieve the effect of partial suction, and cannot achieve the purpose of completely avoiding it. Therefore, the traditional blackboard has a large amount of dust during use, and the indoor air environment is poor. In particular, there is a serious threat ...
