Abstract
The utility model provides a dust-proof blackboard eraser. When being used for cleaning the blackboard, the blackboard eraser can absorb chalk dust falling from the blackboard, thus preventing the chalk dust from spreading in terms of the source, and guaranteeing classrooms to be sanitary and clean. The dust-proof blackboard eraser comprises a holding part and an erasing head made of cotton cloth and positioned on the holding part, wherein the holding part is provided with a hollow containing cavity, sponge is filled in the cavity, a plurality of water guiding channels communicated with the containing cavity and the erasing head are arranged on the contact surface of the holding part and the erasing head, and a water injecting channel communicated with the containing cavity and a water source is also arranged on one of other surfaces of the holding part. As one optimal scheme, the water injecting channel is arranged on the side wall of the holding part; and as another optimal scheme, the water guiding channel is arranged into a rectangular/annular array.
Description
Technical field
The utility model relates to a kind of teaching equipment, especially a kind of dust-proof blackboard eraser.
Background technology
Blackboard in daily teaching is the plane that can write repeatedly, and the plate face is hard, abuts against on the wall.When the font wiped with blackboard eraser on the blackboard, consume a large amount of muscle power and unhygienic, make to be full of dust in the classroom, easily by human body inspiration lung, influence healthy.Therefore, the teacher who had been a teacher for many years suffers from sphagitis even pneumoconiosis easily, is very unhygienic and expend a muscle power work owing to erase the board, and the student erases the board also very unwilling.
Summary of the invention
The utility model provides a kind of dust-proof blackboard eraser, and when erasing the board, it can adsorb the chalk powder that drops on the blackboard, has placed the diffusion of chalk powder from the source, has guaranteed teacher's hygiene.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of dust-proof blackboard eraser of the utility model comprises the grip part and is positioned at the wiping head of being made by cotton on the grip part that there is the ccontaining cavity of hollow described grip part, this cavity filling sponge; The some conduit pipes that are communicated with ccontaining cavity and wipe are set on this grip part and the contact-making surface of wiping head; The waterflood path that is communicated with ccontaining cavity and water source also is set on one of other face of this grip part.
As a kind of preferred version of the present utility model, described waterflood path is arranged on the sidewall of grip part.
As another kind of preferred version of the present utility model, described conduit pipe rectangular array.
As another preferred version of the present utility model, described conduit pipe annular array is arranged.
Owing to be provided with water-absorbing sponge in the containing cavity body cavity body of the present utility model, the water that injects from waterflood path can be stored in the sponge.When erasing the board, the water in the sponge makes that the powder on the cotton is moistening because the principle of siphon enters the wiping head that cotton is made by conduit pipe, and diffusivity reduces greatly.In addition, because cotton moistening, the coefficient of friction of itself and blackboard reduces leicht fallen D/A during blackboard wiping.Moreover, water of this blackboard eraser perfusion can wiping blackboard several times, convenient and swift.The utility model has only several parts, and is simple in structure, with low cost, but obtains good technical effect.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural profile schematic diagram of the present utility model.
Among the figure: 1 grip part, 2 wipe head, 3 sponges, 4 conduit pipes, 5 waterflood paths.
The specific embodiment
As shown in Figure 1, a kind of dust-proof blackboard eraser of the utility model comprises grip part 1 and is positioned at the wiping of being made by cotton 2 on the grip part 1 that there is the ccontaining cavity of hollow described grip part 1, this cavity filling sponge 3; This grip part 1 with wipe a contact-making surface of 2 on the some conduit pipes 4 that are communicated with ccontaining cavity and wiping 3 are set; The waterflood path 5 that is communicated with ccontaining cavity and water source also is set on one of other face of this grip part 1.
Owing to be provided with water-absorbing sponge 3 in the containing cavity body cavity body of the present utility model, the water that injects from waterflood path 5 can be stored in the sponge 3.When erasing the board, the water in the sponge 3 makes that the powder on the cotton is moistening because the principle of siphon enters wiping that cotton makes 2 by conduit pipe 4, and diffusivity reduces greatly.In addition and since cotton wipe 2 moistening, the coefficient of friction of itself and blackboard reduces leicht fallen D/A during blackboard wiping.Moreover, water of this blackboard eraser perfusion can wiping blackboard several times, convenient and swift.The utility model has only several parts, and is simple in structure, with low cost, but obtains good technical effect.
As a kind of preferred version of the present utility model, described waterflood path 5 is arranged on 1 sidewall of grip part.Adopt this structure can make water filling more convenient, and be difficult for damaging.
As another kind of preferred version of the present utility model, described conduit pipe 4 rectangular array adopt this structure to make easily.
As another preferred version of the present utility model, described conduit pipe 4 annular arrays are arranged, and adopt this structure to make easily.
