Description

A kind of blackboard teaching aid for removing chalk dust

Technical field

The utility model belongs to teaching equipment field, in particular to a kind of blackboard teaching aid that can remove chalk dust.

Background technique

Currently, black board teaching is still most effective teaching equipment, the frequency of use in classroom is high.Tradition is black Plate, some ground glass, some are made of cement plaster, and some moppings on iron sheet panel are made.However, no matter which kind of is black Plate all has that the dust of accumulation is not easily cleaned.Traditional blackboard needs people to hold blackboard eraser repeatedly when cleaning Often in air, teacher and students sitting in the front row are only for disperse for cleaning, time and effort consuming, and the chalk dust of blackboard eraser erasing It not guilty can serve as " dust catcher ", frequent inhalation of chalk dust is very big to lung's injury of people, we also often hear that some are old The long-term inhalation of chalk dust of Shi Yinwei causes the thing of pulmonary disease.

In the prior art, there are a kind of blackboard with automatic ash removing device, number of patent application: 201720190814.5； The applying date: 2017.02.28；Publication number: 206884545 U of CN；Publication date: 2018.01.16；Its structure includes motor, guide rail And lead screw, guide rail and lead screw are horizontally set at the top of blackboard, are provided with sliding block in guide rail；Motor is connected with lead screw one end, connection Axis device is fixed on coupler casing, and range sensor is provided on coupler casing, and range sensor is connected with PLC, motor It is connected with PLC；It is vertically arranged with the hairbrush shell that can be moved left and right on sliding block, is provided in hairbrush shell and is connected with lead screw Brush axle is provided with the hairbrush that can carry out wiping ash to blackboard on brush axle；It blackboard bottom and is provided between fur side For collecting the dust box of dust；It is provided with dust-absorbing mouth between adjacent fur side, and is provided with dust catcher at dust-absorbing mouth.The dress It sets using lead screw transmission, lead screw band electric brush is mobile, letter written with chalk is wiped, disadvantage is that: the collection ash effect of dust box is poor, Chalk dust is easy to fall on outside dust box；Dust catcher can only pinpoint suction ash, and dust suction range is small；Structure is complicated for device, manufacturing cost It is higher.

Utility model content

The purpose of the utility model is to provide the blackboard teaching aids that one kind can remove chalk dust, can will fall in the gear of blackboard Chalk dust on hawk is quickly removed completely, easy to operate, time saving and energy saving.

Purpose of the utility model is realized as follows: a kind of blackboard teaching aid that can remove chalk dust, including blackboard, it is black Be equipped with horizontal dust block board on the downside of plate, the blackboard bottom is equipped with the interior air port that an at least row is spaced apart, each interior air port with Wind box is connected, and air duct is equipped in wind box, and at blackboard rear, the corresponding interior air port in the blackboard bottom is equipped with keeps out the wind the setting of wind box Plate, wind deflector are slidably connected with blackboard, and corresponding interior air port is equipped with an outer air port on wind deflector, and suction ash is connected on outer air port Pipe, the setting corresponding with dust block board of the dust-absorbing mouth of ash sucking tube；One end of the wind box is connected with the dust import of cyclone dust collectors, Cyclone dust collectors are vertically arranged, and the exhaust outlet of cyclone dust collectors is connected with air-exhausting duct, and air-exhausting duct is equipped with blower, cyclone dust collectors Bottom is equipped with Chu Chendou.

When utility model works, blower is opened, and blower is sucked the chalk dust fallen on dust block board by ash sucking tube left Air port in side, remaining interior air port are blocked by wind deflector, and the chalk dust into interior air port enters cyclone dust collectors, whirlwind along air duct Deduster is by chalk dust and air separation, and dust is fallen in storage dirt bucket, and air is discharged from exhaust outlet；Move right wind deflector, moves During dynamic, the ash sucking tube on outer air port is corresponding with each interior air port respectively, and ash sucking tube is complete by the chalk dust on dust block board In portion's sucking storage dirt bucket.It compared with prior art, the utility model has the beneficial effects that: can be by the chalk dust on dust block board It all removes completely, the range for removing chalk dust is big, and effect is more preferable；It is easy to operate, it is time saving and energy saving.

In order to reduce noise, student not being influenced and is attended class, the blower is arranged in outdoor.

In order to enable structure is more compact, the thickness of the blackboard is equal to the axial length in interior air port and the axial direction in outer air port The sum of length.

In order to enable wind deflector movement is more convenient and smooth, wind deflector is corresponded on the blackboard, and horizontal be equipped with above is led respectively Rail and lower guideway, the upper side and lower side of wind deflector respectively corresponds upper rail and lower guideway is equipped with top shoe and sliding block.

In order to improve the suction ash effect of ash sucking tube, the ash sucking tube is set as horn-like.

As the improvement of the utility model, the cyclone dust collectors are scroll casing type cyclone dust collectors, and storage dirt bucket is removed with whirlwind Dirt device is threadedly coupled.When the amount for storing up the chalk dust collected in dirt bucket is more, Chu Chendou can be disassembled, outwell chalk dust, Then proceed to using.

In order to guarantee that wind deflector can shelter from each interior air port, the length of the wind deflector is 2 times of blackboard length, exogenous wind Mouth is arranged in the middle part of wind deflector, and one end of wind deflector is equipped with pull handle.Pull wind deflector mobile by pull handle, movement is more Add conveniently.
