Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Embodiment 1
Referring to Fig. 1 and Fig. 2, a kind of automatic chalk dust absorption type blackboard eraser of the utility model, including chalkboard eraser main body, chalkboard eraser master
Internal portion is set as hollow form, and hollow cavity is the first cavity, the second cavity and third cavity by barrier partitions, respectively as not
Same function division.
First cavity is brush board cavity 3, driving motor 4 is equipped in brush board cavity 3, driving motor 4 passes through in-built electrical
Source is powered, and built-in power can use rechargeable battery or is directly powered by USB.The transmission shaft of driving motor 4
On powered brush 5, several brushing pieces 502 that powered brush 5 has centrally located axle sleeve 501 and is surrounded on around axle sleeve 501 are installed
Composition, powered brush 5 are fixedly connected by axle sleeve 501 with the end of 4 transmission shaft of driving motor, drive brushing piece 502 by axle sleeve 501
Rotation.For wiping blackboard chalk trace, the ontology of brushing piece 502 is made brushing piece 502 of magnetic material, can be directly by chalkboard eraser
It is adsorbed on the blackboard of metal material and realizes fixation.It is contacted as shown in figure 3, pasting to be fixed on the ontology of brushing piece 502 with blackboard
Swipe 504, swipe 504 can be made of the wear-resistant materials such as felt, sponge.In the opening on one side towards blackboard of brush board cavity 3
Air intake vent 6 equipped with several bar shapeds.Meanwhile it being also provided with air intake vent 6 in four sides of brush board cavity 3, for collecting laterally more
Unrestrained dust.
Second cavity is dust suction cavity 2, and the dust catcher being connected with power supply is equipped in dust suction cavity 2, and dust catcher generates
Negative pressure is collected dust.The air inlet of dust catcher is connected to brush board cavity 3, and the powder under 5 roll brush of powered brush is in dust suction
Successively enter in dust catcher by air intake vent 6, brush board cavity 3 and air inlet under the suction-operated of device, the meal outlet of dust catcher with
The connection of third cavity.
Third cavity is storage cavity 1, and storage cavity 1 is connected to the meal outlet of dust catcher by flour extraction pipe road, is being stored
The back side of cavity 1 is equipped with the switch button being electrically connected with dust catcher and driving motor 4, and switch button is for controlling dust catcher and drive
Dynamic 4 either on or off of motor.Third cavity connect by detachable structure with the second cavity, is stored in third cavity when that need to topple over
When powder, then third cavity is separated by detachable structure.One kind of detachable structure is achieved in that using slide construction, sliding
Dynamic structure includes that the sliding slot offered on the second cavity and the strip for cooperating with sliding slot on third cavity are slided
Block.When needing to dismantle, sliding block directly can be skidded off into sliding slot, then separate two chambers.Store the gas outlet of cavity 1
Before need to be equipped with dirt filtrating screen, prevent internal dust to be discharged from gas outlet.But the aperture of dirt filtrating screen is too small to be easy to cause windage
It is excessive, efficiency of dust collection is influenced instead.Therefore, it in order to increase the absorption of stemness dust, stores porous filled with hygrometric state in cavity 1
Adsorbent material, such as mandruka, the participated sponge of water suction etc..
Embodiment 2
The present embodiment the difference from embodiment 1 is that, as shown in Figures 4 and 5,502 periphery of all brushing pieces of powered brush 5 is surround
There is a ring body 503,503 bottom of ring body is concordant close to blackboard side with brushing piece 502.The side that ring body 503 is contacted with blackboard
Material identical with swipe 504 can also be used.Due to the utility model be by powered brush 5 to blackboard carry out it is clean, because
The generating source of this dust mainly in 502 position of brushing piece, the setting of ring body 503 dust can be efficiently controlled in it is internal without
It is lost in ambient enviroment.By experiments have shown that, after being wiped for identical blackboard writing on the blackboard, the dust collection of the present embodiment
Weight increases 10.3% compared with the chalkboard eraser for not setting ring body 503, shows that its dust collection efficiency is greatly promoted.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Ability
Field technique personnel are described in the above embodiment and specification it should be appreciated that the present utility model is not limited to the above embodiments
