Description
Technical field
This utility model relates to realia, specifically a kind of electric dust-suction blackboard eraser。
Background technology
Education is always up the most important thing of national development, and whether the development of any industry all open or not education, educates and provides high-quality talents into China, a national development is played an important role。And blackboard is essential as a part important in teaching, blackboard eraser is particularly significant as a kind of and that blackboard is supporting instrument, blackboard eraser currently on the market not only has a large amount of dust when blackboard wiping, have a strong impact on front-seat student learning, and the person is harmful to by the dust produced, the student erased the board and teacher just can be clean by blackboard-cleaning by certain strength, inconvenient, so designing the blackboard eraser for teaching of a kind of improvement。And at present, after the blackboard eraser blackboard wiping that teaching uses, it is easy to cause dust from flying, have a strong impact on the healthy of teachers and students。
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of electric dust-suction blackboard eraser。
To achieve these goals, this utility model be the technical scheme is that a kind of electric dust-suction blackboard eraser, including blackboard eraser body, motor, adhesive hair seat, dust absorption fan, dust accommodating chamber and electric supply installation；Described blackboard eraser body left surface is provided with electric supply installation and motor, described motor output shaft is provided with rotating shaft, and the inner chamber of blackboard eraser body is provided with dust absorption fan, described dust absorption fan is enclosed within rotating shaft, and rotating shaft one end is arranged on adhesive hair seat, covering of the fan is just to blackboard eraser body bottom surface, described dust absorption fan is electrically connected with electric supply installation by switching, and switch is arranged on blackboard eraser body upper end, it is provided with drainage screen between described dust absorption fan and adhesive hair seat, drainage screen and blackboard eraser body right flank composition dust accommodating chamber, dust accommodating chamber lower end is provided with dust export, the nearly left surface place, bottom of described blackboard eraser body is provided with exhaust outlet。
Further, on the left of described blackboard eraser body, hands handle is installed。
Further, described adhesive hair seat is provided with air suction opening and adhesive hair。
Further, it is provided with charging jacks on the left of described electric supply installation。
Adopt after technique scheme, this utility model compared to the prior art advantageously:
Electric dust-suction blackboard eraser described in the utility model, pull switch, closing of circuit, dust absorption fan works, and dust enters blackboard eraser body inner chamber from air suction opening, and due to the barrier effect of drainage screen, dust accumulation is at dust accommodating chamber；Alleviate dust from flying, it is ensured that the health of teachers and students, by being provided with handle, blackboard eraser can be held very easily, and by rotating shaft one end is arranged on adhesive hair seat, when energized, adhesive hair seat can be driven to rotate, it is not necessary to artificial wiping repeatedly, alleviate the workload of teacher。
