Abstract
The invention discloses an electric blackboard eraser. The electric blackboard eraser comprises a shell, a handle, a switch, an electric motor, a fan, a dust cup filter, a dust cup, a soft horn mouth and a three-blade type small brush, and belongs to the technical field of small vacuum dust collectors. The electric blackboard eraser is characterized in that the dusting is finished by wiping up chalk characters written on a blackboard through relative movement between the brush driven by the motor and the blackboard, and dust is sucked in the dust cup through a dust sucking port formed in the horn mouth; after the filtration is performed through the dust cup filter, clean air is exhausted by an exhaust hole, and dust particles are remained in the dust cup, so that an excellent working and learning environment is created for teachers and students, and the health of the teachers and the students is effectively protected; and the electric blackboard eraser has an active effect, and is a revolutionary innovation of blackboard erasers.
Description
Technical field
The invention belongs to compact vacuum cleaner technical field, is specifically related to a kind of electric blackboard eraser.
Background technology
Chalk is the more teaching aid of school's routine use, and at present, in the various kinds of schools of China, classroom instruction is substantially still taking letter written with chalk writing on the blackboard as main.According to relevant mensuration, teacher only has a small amount of chalk dust stick to your hands or fall along with writing in the time writing with chalk word, and more than 95% dust granules falls or floats and flies upward in the process erasing the board.Dust not only easily make dirty clothing, pollute indoor environment, and lung, respiratory tract, eyes, skin, ear to people all can have injury in various degree.
Summary of the invention
In order to address the above problem, the invention provides a kind of electric blackboard eraser.
In order to achieve the above object, the invention has adopted following technical proposals:
A kind of electric blackboard eraser, comprises housing, handle, switch, electro-motor, fan, dirt cup filter, dirt cup, soft horn mouth, cloverleaf small brushes.Clear up for convenience dust, the shell split design of the shell of dirt cup and electro-motor and fan, and connect by screw thread mode, cloverleaf hairbrush is placed in horn mouth by brush axle, the other end of brush axle is directly connected on motor, and providing power by motor, a kind of power switch of electric blackboard eraser is arranged on handle.
After turning on the power switch, electro-motor and fan are just started working, and the cloverleaf hairbrush being driven by electro-motor is also started working.Cloverleaf hairbrush utilizes the relative motion between itself and blackboard, the letter written with chalk writing on the blackboard is wiped clean and completed dirt, in this simultaneously, chalk particle is owing to there being soft bell-mouthed " shielding " effect, it can not arbitrarily be floated in air, but suck dirt cup by the suction port being placed in horn mouth.Therefore, a kind of electric blackboard eraser, for ensureing that teachers and students have a good working and learning environment, is protected the healthy of teachers and students effectively, has very positive effect, is the revolution innovation of blackboard eraser.
Brief description of the drawings
Fig. 1 is a kind of electric blackboard eraser generalized section of the invention.
Wherein, the soft horn mouth of 1-; 2-suction port; 3-brush axle; 4-dirt cup; 5-dirt cup filter; 6-fan; 7-electro-motor; 8-steam vent.
Fig. 2 is the audio-visual picture of a kind of electric blackboard eraser of the present invention.
Wherein, 1-dirt cup shell and electro-motor shell junction; 2-power switch; 3-power line.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of electric blackboard eraser of the invention is described further.
As shown in Figure 1, a kind of electric blackboard eraser comprises soft horn mouth 1, suction port 2, and cloverleaf brush axle 3, dirt cup 4, dirt cup filter 5, fan 6, electro-motor 7, steam vent 8, and in Fig. 2, be arranged on the power switch 2 on handle.
When turning on the power switch 2, electro-motor 7, fan 6 are just started working, the cloverleaf hairbrush that is arranged on brush axle 3 other ends just starts to rotate, when cloverleaf hairbrush utilizes the relative motion between itself and blackboard, the letter written with chalk writing on the blackboard is wiped clean and completed after dirt, and dust just sucks in dirt cup by the suction port 2 being arranged in horn mouth, after filtering by dirt cup filter 5, clean air is discharged by steam vent 8, and dust granules has been stayed in dirt cup.
