Abstract
The repeatedly used dust-removing blackboard eraser in this utility model plate face, including plate face and hairbrush, plate face and hairbrush are sticked together by magic power, the inner hollow in plate face forms cavity, and the top side of cavity is provided with a water injection hole, and the bottom of cavity is provided with plural water seepage hole, the sealing that is provided above with of water injection hole is covered, a diameter of 1mm～2mm of water seepage hole, the centre position of cavity top is embedded with one block of Magnet, the length of Magnet and a width of plate face length and wide half.Hairbrush of the present utility model and plate face are by magic bonding, after hairbrush weares and teares, it is only necessary to more Brusher being able to change bristles, it is not necessary to all change, the most energy-conservation environmental protection again；In the cavity of plate face, injected clear water is permeated by water seepage hole and makes hairbrush keep humidity to hairbrush, thus has certain absorption property, reduces flying upward of powder；Blackboard eraser is embedded in Magnet, is adsorbed in blackboard and is prone to find.
Description
Technical field
This utility model belongs to teaching aid technical field, relates to a kind of repeatedly used dedusting in plate face black
Blackboard eraser.
Background technology
Currently used blackboard eraser is disposable mostly, the most straight after the abrasion of hairbrush Reusability shortens
Connect and abandon, but the plate face of blackboard eraser still stands intact, and so causes the significant wastage of resource.
Meanwhile, can produce a large amount of dust during the use of blackboard eraser, dust flies away can be to teacher and week
The student on limit is healthy produces harm.
Utility model content
The purpose of this utility model is to provide the repeatedly used dust-removing blackboard eraser in a kind of plate face, solves existing
There is the problem that the wasting of resources and dust fly away present in technology.
This utility model be employed technical scheme comprise that, the repeatedly used dust-removing blackboard eraser in plate face, including
Plate face and hairbrush, plate face and hairbrush are sticked together by magic power.
Of the present utility model it is further characterized in that,
The inner hollow in plate face forms cavity, and the top side of cavity is provided with a water injection hole, cavity
Bottom is provided with plural water seepage hole.
The sealing that is provided above with of water injection hole is covered, a diameter of 1mm～2mm of water seepage hole.
The centre position of cavity top is embedded with one block of Magnet, the length of Magnet and a width of plate face length and wide
Half.
The beneficial effects of the utility model are, hairbrush and plate face are by magic bonding, after hairbrush weares and teares,
Have only to more Brusher being able to change bristles, it is not necessary to all change, the most energy-conservation environmental protection again；In the cavity of plate face, injected clear water leads to
Cross water seepage hole to permeate and make hairbrush keep humidity to hairbrush, thus there is certain absorption property, reduce powder
Fly upward；Blackboard eraser is embedded in Magnet, is adsorbed in blackboard and is prone to find.
Accompanying drawing explanation
Fig. 1 is the structure chart of the repeatedly used dust-removing blackboard eraser in this utility model plate face.
In figure, 1. plate face, 2. hairbrush, 3. magic power is glued, 4. Magnet, 5. cavity, 6. water injection hole, 7. water seepage hole.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
The repeatedly used dust-removing blackboard eraser in this utility model plate face, structure is as it is shown in figure 1, include plate face
1 and hairbrush 2, plate face 1 and hairbrush 2 glue 3 by magic power and be sticked together.
The inner hollow in plate face 1 forms cavity 5, and the top side of cavity 5 is provided with a water injection hole 6,
The bottom of cavity 5 is provided with plural water seepage hole 7.
The sealing that is provided above with of water injection hole 6 is covered, a diameter of 1mm～2mm of water seepage hole 7.
The centre position at cavity 5 top is embedded with one block of Magnet 4, and the length of Magnet 4 and a width of plate face 1 are long
With wide half.
The repeatedly used dust-removing blackboard eraser in this utility model plate face, uses a period of time to pass through when hairbrush 2
Repeatedly after fretting wear, directly tearing, the hairbrush 2 more renewed, plate face 1 then can be with iterative cycles
Use, energy-conservation environmental protection again.
Can pass through water injection hole 6 injected clear water in cavity 5 in plate face 1, clear water can be with after being finished
Time supplement, clear water is permeated by water seepage hole 7 and makes hairbrush 2 keep moist to hairbrush 2, thus has certain
Absorption property, reduce the flying upward of powder.
The setting of plate face 1 internal magnet 4, for being adsorbed in blackboard after blackboard eraser makes to be finished, it is easy to
Searching when next time uses.
