Description
Technical field
This utility model belongs to educational aid field, is related to a kind of chalkboard eraser, particularly belongs to a kind of Novel chalk eraser device.
Background technology
Teachers in primary and middle schools' major part uses blackboard, teacher to write using chalk per class at present, causes classroom usually chalk
Ash flies upward, and causes a kind of burden to the health of class, while the chalk dust for causing is very easy to by teacher and front-seat student's suction
In vivo, what resistance was poor easily causes respiratory tract infection etc., and the handss of teacher are also usually packed dust, clothes hair etc. and are also usually stained with
Full chalk dust.
Write using chalk simultaneously and imparted knowledge to students, chalk is separated with blackboard eraser, and word is wrongly write when teaching will also be with hand-held
Blackboard eraser to be wiped, in teaching, blackboard eraser is used with the phase separation of chalk, is saved the class period for teachers ' teaching and is brought
Many inconvenience, cause sometimes teacher directly to use handss erasing blackboard word.
As middle and primary schools and institution of higher learning's teaching task are very heavy, blackboard Jing often writes the another face of one side, holds time not
It is long, even if also wiping unclean using blackboard eraser, the normal water-washing blackboards of Jing are needed, this gives the cleaning blackboard work of corresponding Faculty and Students
Bring many burdens.
The content of the invention
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is to propose a kind of novel chalk
Device is wiped, by arranging chalk holder device, adsorbable chalk dust, erasable letter written with chalk, washable blackboard are simple and practical, significantly
The suction of human body chalk dust is reduced, numerous and diverse instrument that class clears up blackboard sanitary tool is reduced, the unnecessary waste of teaching is saved
Time, mitigate the burden that Faculty and Students clear up chalk dust.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of Novel chalk eraser device, the Novel chalk eraser device include that strength is inhaled the velveteen chalk sheath of ash, arranged
The erasing apparatus of the turn buckle and turn buckle connection at the palm axis joint on velveteen chalk sheath and three are used for fixed erasing
The fixing band of device, the erasing apparatus are three layers oval, and turn buckle is connected with one end of ellipse, and three layers include outermost layer
Blackboard snag core, the high-density sponge in intermediate layer and internal layer mesh tank box.
The strength inhales the knitting wool thread gluing that the surface of the velveteen chalk sheath of ash is provided with static electrification, and knitting wool thread gluing is provided with hair
Line fine hair.The one end of the fixing band with erasing apparatus away from turn buckle is connected, three fixing bands respectively with outermost blackboard
The mesh tank box connection of snag core, the high-density sponge in intermediate layer and internal layer.The two ends of the turn buckle and velveteen chalk handss
Set is fixed, and the middle part of turn buckle is connected with erasing apparatus.The looping of the velveteen chalk sheath is arranged with and is provided with some installations
Hole and by through installing hole controlling the elastic tension rope of the running-on part of velveteen chalk sheath.The velveteen chalk sheath
Running-on part edge provided Velcro velcro.It is provided with inside the velveteen chalk sheath of the Novel chalk eraser device and adds
Thermal modules.Dismountable sweat-absorbing layer is additionally provided with inside the velveteen chalk sheath of the Novel chalk eraser device.
A kind of using method of Novel chalk eraser device, step one：Novel chalk eraser device is passed through velveteen powder by user
Glove donning is on hand, and writes by chalk；Step 2：The chalk dust of generation of writing falls down, due to the appearance that staff is used
Gesture is to bend, and now strength is inhaled grey velveteen glove and the chalk dust for falling down adsorbed from surrounding, if there is faint wind write
When chalk dust blow toward surrounding, now strength inhale ash velveteen chalk sheath on band many static electrification knitting wool thread gluings knitting wool
Fine hair is also swung with the wind, adsorbs to surrounding the chalk dust for flying upward, and due to carrying electrostatic, its adsorption effect and scope are advantageously；
Step 3：The fixing band being connected with blackboard snag core at elbow can be opened during letter written with chalk on erasing blackboard, rotation rotation
Button, blackboard snag core is rotated to this one side of palm, by static electrification knitting wool thread gluing subsidiary on velveteen glove by blackboard eraser core
Fix on palm, the word on erasing blackboard is carried out with palm；Step 4：Blackboard needed to be cleared up with water through a period of time,
Can then previous step third step, fixing band be connected with high-density sponge for continuing to open at elbow is opened, and high density is extra large
Silk floss is rotated to palm, and high-density sponge is fixed on palm by static electrification knitting wool thread gluing subsidiary on velveteen glove, then by net
After hole tank box adds appropriate water, by rotating turn buckle, press on rotation high density sponge so that high-density sponge is moistened
Afterwards, mesh tank box is rotated back to into original position again and elbow is fixed on by fixing band, now the high-density sponge of palm can be against
Blackboard carries out cleaning blackboard.
This utility model beneficial effect is:Adsorbable chalk dust, erasable letter written with chalk, washable blackboard are simple and practical, greatly
The big suction for reducing human body chalk dust, reduces numerous and diverse instrument that class clears up blackboard sanitary tool, saves the unnecessary waste of teaching
Time, mitigate Faculty and Students clear up chalk dust burden.
