Abstract

The utility model belongs to the technical field of small-sized vacuum cleaners and discloses a dust-absorption type power-driven blackboard eraser which comprises a shell body, a handle, a switch, an electric motor, a fan, a dust cup filter, a dust cup, a soft horn mouth and a three-leaf brush. The electric motor is used to drive the brush and a blackboard to move relatively, and the dust-absorption type power-driven blackboard eraser wipes off chalk characters written on the blackboard so as to complete dusting. Dust is absorbed into the dust cup through a dust absorption mouth arranged in the horn mouth and then filtered through the dust cup filter. Clean air is discharged out through vent holes, but dust particles are left in the dust cup. Therefore, the dust-absorption type power-driven blackboard eraser has positive functions for effectively protecting health of teachers and students and guaranteeing the teachers and the students have a good working and studying environment, and is a revolutionary innovation of blackboard erasers.

Description

A kind of dust absorbing electric eraser

Technical field

The utility model belongs to the compact vacuum cleaner technical field, is specifically related to a kind of dust absorbing electric 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 basically still take the letter written with chalk writing on the blackboard as main.According to relevant mensuration, the teacher only has a small amount of chalk dust to stick to your hands when writing with chalk word or falls along with writing, and the dust granules more than 95% falls in the process that erases the board or floats and flies upward.Dust not only easily make dirty clothing, pollute indoor environment, and to people's lung, respiratory tract, eyes, skin, ear injury in various degree can be arranged all.

Summary of the invention

In order to address the above problem, the utility model provides a kind of dust absorbing electric eraser.

In order to achieve the above object, the utility model has adopted following technical proposals:

A kind of dust absorbing electric eraser comprises housing, handle, switch, electro-motor, fan, dirt cup filter, dirt cup, soft horn mouth, cloverleaf small brushes.Be the easy cleaning dust, the shell split design of the shell of dirt cup and electro-motor and fan, and connect with the screw thread mode, the cloverleaf hairbrush places in the horn mouth by brush axle, the other end of brush axle directly is connected on the motor, and providing power by motor, the power switch of Portable dust-free blackboard eraser then is arranged on the handle.

After turning on the power switch, electro-motor and fan are just started working, and are also started working by the cloverleaf hairbrush that electro-motor drives.The cloverleaf hairbrush utilizes the relative motion between itself and the blackboard, the letter written with chalk that writes on the blackboard is wiped clean and finished dirt, in this simultaneously, the chalk particle is owing to there being soft bell-mouthed " shielding " effect, it can not arbitrarily be floated in air, but by placing the suction port in the horn mouth to suck the dirt cup.Therefore, a kind of dust absorbing electric eraser is protected the healthy of teachers and students effectively for ensureing that teachers and students have a good working and learning environment, has very positive effect, is the revolution innovation of blackboard eraser.

Fig. 1 is the generalized section of a kind of dust absorbing electric eraser of the utility model.

Wherein, the soft horn mouth of 1-; The 2-suction port; The 3-brush axle; 4-dirt cup; 5-dirt cup filter; The 6-fan; The 7-electro-motor; The 8-steam vent.

Fig. 2 is the audio-visual picture of a kind of dust absorbing electric eraser of the utility model.

Wherein, 1-dirt cup shell and electro-motor shell junction; The 2-power switch; The 3-power line.

The specific embodiment

Below in conjunction with accompanying drawing, a kind of dust absorbing electric eraser of the utility model is described further.

As shown in Figure 1, a kind of dust absorbing electric 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 be arranged on power switch 2 on the handle among Fig. 2.

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 begins to rotate, when the cloverleaf hairbrush utilizes relative motion between itself and the blackboard, the letter written with chalk that writes on the blackboard wiped clean and after having finished dirt, dust just sucks in the dirt cups by the suction port 2 that is arranged in the horn mouth, after filtering by dirt cup filter 5, the air of cleaning is discharged by steam vent 8, and dust granules has then been stayed in the dirt cup.

Claims

1. dust absorbing electric eraser, comprise housing, handle, switch, electro-motor, fan, dirt cup filter, dirt cup, soft horn mouth, cloverleaf small brushes, it is characterized in that: utilize described electro-motor to drive described cloverleaf small brushes rotation, wipe clean the letter written with chalk that writes on the blackboard.

2. dust absorbing electric eraser according to claim 1 is characterized in that: the dust that described hairbrush has been wiped can not arbitrarily be floated it by soft horn mouth " shielding " in air.

3. dust absorbing electric eraser according to claim 1 is characterized in that: the dust that described hairbrush has been wiped sucks dust in the dirt cup by suction port by running up after motor and the fan energising.
