The invention discloses a blackboard eraser with a dust collection function and a dust discharge mechanism thereof, and relates to the technical field of teaching equipment. The blackboard eraser comprises a blackboard eraser main body, a dust collection mechanism, a charging mechanism and a base mechanism, and a control button is arranged at one side of the outer wall of the blackboard eraser main body. According to the blackboard eraser, a suction fan, a fixed rod, a filter screen, a sliding clamping block, a first clamping groove, a second clamping groove, a third clamping groove, a slidinggroove, a connecting hole, a lifting groove, a ventilation plate, a hole, a telescopic column, a first spring, a movable clamping block, a connecting clamping block, a movable side plate, a fixed clamping block, a chalk eraser, a control button, a dust collecting mechanism, a collecting box, a collecting bin, limiting columns, limiting holes, a sliding block, a sliding rail, a limiting groove, alimiting block, a second spring and a connecting rod are arranged, so that the dust collection function of the blackboard eraser is achieved, and dust cleaning is facilitated; and dust can be sucked into a collection bin through suction force generated by the suction fan, and the dust collection effect of the blackboard eraser can be effectively improved through cleaning of a collecting box, the filter screen and the chalk eraser.
Description
technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a blackboard eraser with a dust suction function and a dust discharge mechanism thereof. Background technique [0002] Blackboard eraser is an essential product for teaching. Commonly used blackboard eraser is to put the felt into the tin box, and wipe the chalk writing by rubbing between the felt and the blackboard. When the existing blackboard eraser is in use, its chalk dust will Flying into the air and being inhaled into the lungs will cause great harm to the health of teachers and students over time, so blackboard erasers with dust suction function appear. [0003] Existing dust-absorbing blackboard erasers usually use batteries to provide working power, and blackboard erasers are used frequently and for a long time, so they need to be replaced frequently, which affects the use and promotion of blackboard erasers. The chalk eraser and the main body of the eraser ...
