Description
Technical field
The utility model relates to blackboard eraser, is specifically related to a kind of special Environmentally friendly blackboard eraser.
Background technology
In tradition, the general chalk that uses carries out writing on the blackboard at green plate (blackboard), but chalk dust has impact to healthy, and easy contaminated environment, is unfavorable for environmental protection simultaneously.For this reason, the applicant in first patent of invention, (patent No. is: 200910192711.2) disclose a kind of environment-friendly blackboard writing liquid and preparation method thereof.It utilizes environment-friendly blackboard writing liquid to replace chalk writing, thus ensures the health of health, decreases the pollution of environment.After utilizing environment-friendly blackboard writing liquid writing on the blackboard, again write again as needs change after writing on the blackboard content often needs blackboard eraser wiping.At present, the blackboard eraser of use is formed primarily of main body and cleaning part, and cleaning part is fixedly connected with main body.After cleaning part is because of use wearing and tearing, then need whole blackboard eraser to lose, this easily causes waste of material, also easily causes environmental pollution simultaneously.
Utility model content
The purpose of this utility model is the deficiency existed to overcome above prior art, provides a kind of simple and reasonable for structure, avoids waste of material, reduce the special Environmentally friendly blackboard eraser of environmental pollution.
The purpose of this utility model is realized by following technical scheme: this special Environmentally friendly blackboard eraser, and comprise the cleaning part that main body, VELCRO and sponge are made, the one side of described VELCRO is fixed on main body, and described cleaning part is connected with the another side of VELCRO.
Preferably, described main body comprises hand grip portion and connecting plate, described hand grip portion and connecting plate integrally formed.
Preferably, the two sides of described hand grip portion are all set to arc surface, and the width at the middle part of described hand grip portion is greater than the width at its two ends; The two ends in described hand room portion are provided with groove.
Preferably, the thickness of described hand grip portion is 20mm ~ 40mm.
Preferably, described connecting plate is rounded, oval or square.Connecting plate can adopt not same shape, and this easily improves the pattern of Environmentally friendly blackboard eraser, with satisfied different Man's Demands.The shape of connecting plate is not limited only to circle, ellipse or square simultaneously, also can be other shape.
Preferably, be provided with the capping of inner chamber and the opening for closed inner chamber in the middle part of described main body, described capping is connected in the opening of inner chamber.
Preferably, gusset is provided with in described inner chamber.
Preferably, described cleaning part is provided with multiple hole, and the size in described hole is for being 0.5mm ~ 2mm.
The utility model has following advantage relative to prior art: this special Environmentally friendly blackboard eraser improves existing blackboard eraser, cleaning part utilizes VELCRO to be connected with main body, this facilitates the dismounting of cleaning part, when after cleaning part wearing and tearing, only need the cleaning part more renewed, and do not need whole blackboard eraser to abandon, this is avoided causing waste of material, plays the effect of energy-conserving and environment-protective.This special Environmentally friendly blackboard eraser utilizes sponge to make cleaning part, then in the process of wiping, then can be adsorbed in sponge by the blackboard writing liquid of wiping, reduces blackboard writing liquid and becomes scattered about contaminated environment in air, also avoid human body to suck the blackboard writing liquid be scattered.The very convenient dismounting of cleaning part in this special Environmentally friendly blackboard eraser, this facilitates the cleaning of cleaning part.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Special Environmentally friendly blackboard eraser as shown in Figure 1 to Figure 3, comprises the cleaning part 3 that main body 1, VELCRO 2 and sponge are made, and the one side of described VELCRO 2 is fixed on main body 1, and described cleaning part 3 is connected with the another side of VELCRO 2.In use procedure, cleaning part 3 is very convenient is attached to VELCRO 2, to be also very easily separated with VELCRO 2 by cleaning part 3 meanwhile.Therefore when cleaning part 3 adsorbs a certain amount of blackboard writing liquid, torn by cleaning part 3 from VELCRO 2, then by washing clean wiping portion 3, this is clean more convenient, and more effectively, then cleaning part 3 is reusable, plays the effect of energy-conserving and environment-protective.
Described main body 1 comprises hand grip portion 11 and connecting plate 12, described hand grip portion 11 and connecting plate 12 integrally formed.The material that main body 1 in the present embodiment uses is plastics, and it is integrally formed that hand grip portion 11 and connecting plate 12 pass through mould.This Stability Analysis of Structures is firm, convenient manufacture.
The two sides of described hand grip portion 11 are all set to arc surface 4, and the width at the middle part of described hand grip portion 11 is greater than the width at its two ends, and namely two arc surfaces 4 all outwardly; The two ends in described hand room portion 11 are provided with groove 5.In use, forefinger is pressed at a groove 5, and thumb and remaining 3 fingers are positioned at two arc surfaces 4.The setting of arc surface 4 and groove 5 meets ergonomics, and personnel easy to use capture use.
The thickness of described hand grip portion 11 is 30mm.Described connecting plate 12 is square.Meanwhile, the profile of VELCRO 2 and cleaning part 3 all with the mating of connecting plate 12.VELCRO 2 is first fixed on connecting plate 12, and then cleaning part 3 is affixed on VELCRO 2 again.The form fit of cleaning part 3 and connecting plate 12, this makes the size of cleaning part as far as possible large, thus covers connecting plate 12, ensures wiping efficiency.
As shown in Fig. 2, Fig. 4 and Fig. 5, be provided with inner chamber 6 and the capping 7 for the opening of closed inner chamber 6 in the middle part of described main body 1, described capping 7 is connected in the opening of inner chamber 6.Concrete, the opening part of inner chamber is provided with fixture block, and the outer rim of capping is provided with draw-in groove, and the opening of capping and inner chamber carries out clamping, this easy disassembly mutually by fixture block and draw-in groove.Inner chamber 6 is set, the material manufacturing main body 1 can be reduced, thus play the effect of energy-conserving and environment-protective further.And capping 7 can avoid cleaning part 3 to cave in, ensure the wiping effect of Environmentally friendly blackboard eraser.Meanwhile, the manufacture that capping can facilitate main body is set up.
Described inner chamber 6 li is provided with gusset 8.Gusset 8 has multiple, and it intersects in length and breadth, evenly arranges, and this can ensure the intensity of main body 1, the service life that extension plate control is wiped.
Described cleaning part 3 is provided with multiple hole, and the size in described hole is for being 1mm.This makes the sponge of cleaning part for filtration silk floss.There is because filtering silk floss the hole of certain size size, therefore improve the ability that cleaning part 3 adsorbs blackboard writing liquid, reduce blackboard writing liquid further and become scattered about air, reduce the pollution to environment.
Above-mentioned detailed description of the invention is preferred embodiment of the present utility model; can not limit the utility model; the any of other does not deviate from the technical solution of the utility model and the substitute mode of the change made or other equivalence, is included within protection domain of the present utility model.
