Specific embodiment
Below in conjunction with Figure of description, the invention will be further described, but the invention is not limited to following embodiments.
It is as shown in Figs. 1-5 a kind of specific embodiment of environment-friendly dustless blackboard eraser, a kind of environment-friendly dustless blackboard of the embodiment
It wipes, the shell 1 including upper end opening is disposed with filtering layer net 2, strength magnetic stripe 3, dust suction cotton 4 in shell 1 from top to bottom,
Wherein dust suction cotton 4 and 1 bottom interval of shell are arranged and are formed with an accommodation space 5 with the dust for collecting larger particles,
Dust mouth 6 is offered in the bottom of 1 either side of shell, dust mouth 6 is connected to setting with accommodation space 5, by dust mouth 6, makes
The chalk dust in accommodation space 5 can be poured out by obtaining, and there are gap 7, gap 7 and receivings for dust suction cotton 4 and 1 either side of shell
Space 5 is connected to, and on dust suction cotton 4, larger particles can roll little particle dust primary attachment on dust suction cotton 4, and eventually by
Gap 7 is fallen in accommodation space 5, and adhesion has several rub pieces laterally arranged 8 on filtering layer net 2, passes through rub piece 8 and blackboard friction
The adsorbable dust of electrostatic is generated, use process: by blackboard eraser being attached on blackboard on one side with rub piece 8, and carrying out pattern and erase the board
On chalk writings, through rub piece 8 in erasing chalk writings, friction so that chalk dust charge, by be arranged in filtering layer
Strength magnetic stripe 3 between net 2 and dust suction cotton 4 generates magnetic field, the chalk dust of electrification in magnetic field by the effect of power, quickly through
Filtering layer net 2 is collected on dust suction cotton 4, and for short grained dust primary attachment on dust suction cotton 4, larger particles can be on dust suction cotton 4
It rolls, and falls in accommodation space 5 and collect eventually by gap 7, when needing replacing dust suction cotton 4, can successively take filtering layer
After net 2, strength magnetic stripe 3, dust suction cotton 4 is taken out, can also be pulled out dust suction cotton 4 by dust mouth 6, and again by dust mouth 6
It is put into dust suction cotton 4, when being stored with enough chalk dusts in accommodation space 5, can carry out toppling over receipts by dust mouth 6
Collection, simple and practical, blackboard eraser of the invention is environment friendly and pollution-free, and no chalk dust is flown upward；It erases the board clean, quick；Both it can receive
Collect chalk dust, can also concentrate and topple over processing；It is convenient to replace dust suction cotton, using simple；Of simple structure and strong practicability；It is at low cost,
It can volume production；Filtering layer net, dust suction cotton etc. can be replaced, realizes and is recycled, reduce cost, economize on resources.
As an improvement embodiment, as shown in the figures 1 and 2,8 spaced sets of rub piece, the both ends of every rub piece 8 are equal
Extend and sticked on the left and right side of shell 1 respectively, by the left and right side that the both ends of every rub piece 8 are sticked in shell 1
On face, so that blackboard eraser, when contacting friction with blackboard, the edge of shell 1 will not occur hard friction with blackboard and wear blackboard,
The edge of shell 1 has been wrapped by rub piece 8, blackboard has both been avoided and has been damaged, and also avoids ear-piercing the making an uproar of hard friction generation
Sound further improves the work most efficiency of blackboard eraser.
As an improvement embodiment several baffles 9 are horizontally arranged in accommodation space 5 as shown in Figs 1-4,
Baffle 9 vertically divides with 1 bottom of shell and by accommodation space 5 for several storage ash-pits 10, storage ash-pit 10 and the interconnection of 6 phase of dust mouth
It is logical, by the setting of multiple baffles 9, so that the installation of dust suction cotton 4 is stablized, it is not susceptible to local location collapsing, can be accepted more
Chalk dust, while several storage ash-pits 10 chalk dust can be stored in batches, avoid local dust rise roll into a ball and make
It can not normal use at blackboard eraser.
As an improvement embodiment, dust mouth 6 is provided with the bottom of 1 right side of shell, and dust suction cotton 4 and shell 1 are right
There are gaps 7 between side, and of simple structure and strong practicability, gap 7 is closely located to dust mouth 6, convenient for rapid dumps chalk dust
Dirt.
As an improvement embodiment, as shown in figure 4, offering accommodation groove 16, accommodation groove on 2 lower surface of filtering layer net
16 is identical as 3 size of strength magnetic stripe, size, and strength magnetic stripe 3, which can be embedded in, to be mounted in accommodation groove 16 so that in shell 1 compared with
Large space primarily can be used for storage chalk dust, improve the utilization rate of shell 1, meanwhile, strength magnetic stripe 3 can be embedded in installation
In accommodation groove 16, but also it is closer at a distance from blackboard, the magnetic field force of generation is stronger for dust absorption guiding role.
As an improvement embodiment, as shown in figure 4, filtering layer net 2 include first layer Cellular Networks 11, second layer Cellular Networks
12, several carbon lines 13, tridimensional structure are connected between first layer Cellular Networks 11, second layer Cellular Networks 12, so that suck
Chalk dust is not easy to leak out from filtering layer net 2, and carbon line 13 has the characteristics that intensity is high, at low cost, the service life is long, the carbon in the present invention
Plain line 13 can choose the connecting line of other materials.
As an improvement embodiment, as shown in Figure 1,5, rub piece 8 includes silk item 17, is provided with plant in silk item 17
Suede core 14, silk item 17 are smaller to the friction damage of blackboard, and with triboelectrification, flocking core 14 can prop up silk item 17, make
It is obtained with stereochemical structure, has the function of protecting filtering layer net 2 and shell 1.
As an improvement embodiment, as shown in Figure 1, 2, on the left and right side of shell 1 respectively can bolt be provided with
One piece of partition 15, by the setting of partition 15, so that the both ends of every rub piece 8 are fixed, avoiding it from being detached from influences blackboard eraser
Normal use；The junction of adjacent two sides is provided with arc angling on shell 1, both improves aesthetics, also improves hand
The comfort level held.
As an improvement embodiment, drawable in dust mouth 6 to be equipped with drawer, drawer connects dust suction cotton 4, passes through pumping
The setting of drawer so that topple over chalk dust and extraction dust suction cotton 4 it is simpler convenient, of simple structure and strong practicability.
As an improvement embodiment, dust suction cotton 4 be polyester dust suction cotton, have it is good elasticity and durability, especially
It is with electrostatic interaction, convenient for absorbing chalk dust.
Finally it should be noted that present invention is not limited to the above embodiments, there can also be many variations.This field it is general
All deformations that logical technical staff directly can export or associate from present disclosure, are considered as of the invention
Protection scope.
