Abstract

The utility model relates to a dust collector of a blackboard eraser. The utility model comprises a shell and a motor. The shell is provided with an intermediate partition board inside. The intermediate partition board is provided with an air vent in the middle. A rotary shaft of the motor is connected with a wind wheel. The motor and the wind wheel are combined and arranged at one side of the intermediate partition board in the shell. The other side of the intermediate partition board in the shell is provided with a net cover. The net cover is provided with a cyclone separator inside. A box cover with an air inlet is arranged above the shell. The motor rotates in high speed, drives the wind wheel to work, and forms negative pressure. The chalk dust adhered to the surface of a blackboard eraser is sucked following the air, and then, enters into a dust collection box. Most of the dust sinks into the box bottom through the cyclone separator in order to avoid rapidly clogging the net cover. The blackboard eraser and the dust collector of the utility model are separated. The blackboard eraser can be a conventional blackboard eraser. The utility model has the advantages of convenient operation and light weight, adopts alternating currents, and is more convenient and more economic than using direct-current batteries.

Description

Ash collector of eraser

One, affiliated technical field

The utility model relates to a kind of blackboard cleaning device, the particularly a kind of Ash collector of eraser that can remove the chalk dust on blackboard surface in time, neatly.

Two, background technology

The effect of blackboard eraser dust catcher is to remove easily the dust on blackboard surface, improves teaching environment, improves the traditional instruction effect.The relevant patent of domestic applications reaches more than hundred kinds, it is a kind of that its common characteristic is that blackboard eraser and dust catcher are linked as, the feature of mechanization, automation clearly, idealized degree is very high, for example electrical dust-removing blackboard eraser (application number 89109225.0), dust-absorption device for blackboard eraser (91105759.5) etc., all in the improvement of blackboard eraser, write an article, do not obtain practical application because equipment is too complicated or operation is inconvenient.

Three, summary of the invention

The purpose of this utility model is to provide a kind of blackboard eraser to separate with dust collect plant, can handle the dust on the blackboard eraser in time, keeps the clean of blackboard eraser, improves writing effect, improves teaching environment, convenient, healthy Ash collector of eraser.

The technical solution that realizes the utility model purpose is: a kind of Ash collector of eraser, comprise housing, motor, it is characterized in that: central dividing plate is set in the housing, ventilating opening is set in the middle of the central dividing plate, connect wind wheel on the electric machine rotational axis, the combination of motor and wind wheel is arranged on central dividing plate one side in the housing, and the central dividing plate opposite side is provided with guard in the housing, cyclone separator is set in the guard, the housing top is provided with the lid of bringing the air port into.

Operation principle of the present utility model is: the motor high speed rotating, the work of drive wind wheel, cause very big negative pressure, the chalk dust that is bonded at the blackboard eraser surface is sucked in a part of dust-collecting box in back with air, and chalk dust passed through cyclone separator before this, most dust is sunk to box at the bottom of, in order to avoid the very fast obstruction guard of powder ash, influence dust arrester work, post shockproof sponge on the box wall relative, to reduce noise with wind wheel.The inlet scoop is a strip on the lid, and its size is about 120 * 4.5 millimeters, 1～3 of quantity.Cyclone separator is the also side's of can be taper of taper shape.After the dedusting, the blackboard eraser of use when erasing the board, can be wiped the dust on the blackboard totally as before neatly again, keeps the blackboard cleaning clean, improves teaching efficiency.Use this dust arrester, can remove the teacher from and pat blackboard eraser everywhere, dust from flying, contaminated environment also influences teachers ' health.

The utility model compared with prior art, its remarkable advantage is: blackboard eraser separates with dust arrester, blackboard eraser still uses traditional blackboard eraser, and is easy to use, light and handy, adopts the alternating current of 220V, dc-battery is more convenient, more economical than using.

Four, description of drawings

Accompanying drawing is a kind of structural representation of the utility model Ash collector of eraser.

Five, the specific embodiment

Below in conjunction with accompanying drawing, Ash collector of eraser concrete structure described in the utility model is described in further details.

In conjunction with the accompanying drawings, a kind of Ash collector of eraser, comprise housing 1, motor 2, central dividing plate 11 is set in the housing, ventilating opening 14 is set in the middle of the central dividing plate, connect wind wheel 3 on motor 2 rotating shafts, the combination of motor and wind wheel is arranged on central dividing plate one side in the housing, and the central dividing plate opposite side is provided with guard 4 in the housing, cyclone separator 5 is set in the guard, the housing top is provided with the lid 7 of bringing air port 13 into, motor tail end place is provided with shockproof net 12, wind wheel 3 arranged outside silencing pads 10 in the housing.Cover plate 6 and beam 8, motor bottom are set on the motor support 9 is set.Machine operation, drive wind wheel, produce negative pressure in the dust-collecting box frame, the dust on the blackboard eraser surface of lid centre joint top is inhaled in the control of dust screen frame through cyclone separator with air, air is discharged outside the dust arrester around the motor, and the dust major part is received on the wall of cyclone separator and the bottom of screen frame.When needing the cleaning dust, can start lid 7, take out screen frame, outwell dust and get final product.Ash collector of eraser can be rectangular box, volume is about 200 * 100 * 100 millimeters, weight 880 grams, 120 watts of powers of motor, alternating current 220V or direct current 12V, 15000 rev/mins of motor speeds, the inlet scoop on the lid is 100～150 * 4.5 millimeters, the taper of the cyclone separator side of being, guard are that 450～500 order stainless (steel) wires or nylon knitmesh or nonwoven etc. are made.
