22, and the top of snap-springs 22 is connected with fixture block 23, fits closely between water absorption pad 18 and collection box 17, and collection box 17 is logical
Cross fixture block 23 and card road 16 and constitute snap-in structure, by the use of collection box 17, can easily to dust carry out effectively into
Row is collected, it is therefore prevented that and dust is danced in the air to the possibility that user damages device when in use, reduces air pollution, so that
The teaching process of teacher can effectively enhanced, and the use of water absorption pad 18 can prevent existing water tank type black
Blackboard eraser is using leaking, it is therefore prevented that and the possibility that device is damaged when in use improves the using effect of device, so that
The working efficiency of device is effectively enhanced, and cover board 19 and fixed knob 21 and collection box 17 constitute fixed structure, and fixed
To be flexibly connected between knob 21 and collection box 17, the water absorption pad 18 for being filled water is put into collection box 17, cover board is then covered
19, fixed knob 21 is then rotated, cover board 19 and collection box 17 are fixed together, collection box 17 is then put into card road 16
In, then collection box 17 and card road 16 are fixed together under the action of snap-springs 22 are with fixture block 23, pass through snap-springs
22 with the use of fixture block 23, it is therefore prevented that mobile possibility occurs when in use for device, and then prevents collection box 17 and clean box 9
Between generate gap possibility, it is therefore prevented that dust from device come out possibility, reduce the possibility that device breaks down, and
The use of fixed knob 21, which reduces, occurs mobile possibility between cover board 19 when collection box 17 uses, and reduces and then prevents
Dust enters the possibility leaked in device, and then increases the using effect of device, collection box 17 and snap-springs 22
Between to be fixedly connected, and to be fixedly connected between snap-springs 22 and fixture block 23, the top of clean box 9 is equipped with connection ring
24, and the outside of connection ring 24 is mounted with connecting band 25, the top of connecting band 25 is equipped with buckle 26, and connecting band 25 and buckle
To be fixedly connected between 26, there are two the settings of connecting band 25, and it is symmetrical about the central axes of main body 1, and connecting band 25
Detaching structure is constituted by buckle 26 and clean box 9, pulls connecting band 25 to the right, then by the clean box on the insertion of buckle 26 right side
In 9 card slot, fastness when device uses with operator's hand can be increased by the use of connecting band 25, it is therefore prevented that because
The possibility for accidentally causing device and operator's hand to fall off, reduces device and falls from eminence and be indexed to damage
May, reduce the time loss and cost allowance of finishing device, it is therefore prevented that teaching process is affected, and increases making for device
With the service life, the outside of clean box 9 is mounted with adsorption plate 27, and the top of adsorption plate 27 pulls out bar 28 through having, and clean box 9 and inhales
It to be flexibly connected between attached plate 27, and pulls out to be flexibly connected between bar 28 and clean box 9, the top of pull-out bar 28 is connected with solid
Determine ring 29, and pull out to be fixedly connected between bar 28 and fixed ring 29, the bottom of adsorption plate 27 is equipped with absorption stone 30, adsorbs stone
It is bonding connection between 30 and fixed ring 29, while adsorption plate 27 constitutes rotational structure by pulling out bar 28 and clean box 9, outward
Layback moves fixed ring 29, then rotates counterclockwise adsorption plate 27, then presses fixed ring 29 inwardly, by adsorption plate 27 and cleaning
It fixes with clean box 9, can effectively be prevented by the use of fixed ring 29 in device adsorption plate 27 and cleaning when not in use
The possibility being subjected to displacement between box 9, reduce adsorption plate 27 device using when fall off and between blackboard generate friction
Possibility, reduce the possibility that device breaks down, and adsorb stone 30 device when not in use can be Nian Jie with blackboard by it
Together, it is therefore prevented that device thereby reduces the possibility that device is damaged since the generation fallen on desktop.
The working principle of the present embodiment: this has the blackboard eraser of comprehensive dust-absorbing function, first puts the water absorption pad 18 for being filled water
Enter in collection box 17, then cover cover board 19, then rotates fixed knob 21, cover board 19 and collection box 17 are fixed together,
Then collection box 17 is put into card road 16, then by collection box 17 and card road 16 under the action of snap-springs 22 and fixture block 23
It is fixed together, passes through the use of snap-springs 22 and fixture block 23, it is therefore prevented that mobile possibility occurs when in use for device, in turn
Prevent the possibility that gap is generated between collection box 17 and clean box 9, it is therefore prevented that the possibility that dust comes out from device reduces
Then the possibility that device breaks down pulls to the right connecting band 25, then by the card slot of the clean box 9 on the insertion of buckle 26 right side
In, fastness when device uses with operator's hand can be increased by the use of connecting band 25, it is therefore prevented that because accidentally
And the possibility for causing device and operator's hand to fall off, reduce the possibility that device fell and be indexed to damage from eminence,
Reduce the time loss and cost allowance of finishing device, it is therefore prevented that teaching process is affected, and increase device uses the longevity
Life, then device is contacted into wiping with blackboard, sliding pearl 12, using moving in Shi Huixiang collection box 17, then drives in device and adapts to bullet
Spring 11 is shunk, and can reduce the friction between clean box 9 and blackboard by the use of sliding pearl 12, it is therefore prevented that clean box 9 is to blackboard
The possibility of scratch is caused, and reduces the abrasion of clean box 9, reduces the cost of maintenance replacement clean box 9, so that device
Using effect can effectively be enhanced, while 13 operation of dedusting fan, and dust is sent into collection box 17, is being needed to cleaning
When layer 4 is replaced, first passes through fixing bolt 8 and remove whereabouts collection box 7, the use of whereabouts collection box 7, when can use device
The dust of whereabouts is collected, it is therefore prevented that in dust contamination to the clothing of teacher, improves the tidiness of teacher, and reduce
The accumulation of dust on ground pulls limit plate 6 then up, and then clean layer 4 will clean under the action of piston gas bar 2
Layer 4 releases main body 1, and the use by that can dismantle clean layer 4 can easily clean device, reduces device cleaning
Time loss, and can brake release clean layer 4 of piston gas bar 2 reduce clean layer 4 and take out the time being replaced and cleaned
Consumption, increases the clean efficiency of device, enables a device to preferably carry out using here it is this with comprehensive dust-absorbing function
Blackboard eraser working principle.
