Abstract

The utility model discloses an environmental protection blackboard eraser used as a teaching aid and composed of an eraser head (1) and a handle (2). The eraser head (1) is made of sponge, felt or other porous material, the handle (2) is long strip shaped, and the eraser head (1) is installed and fixed on the handle (2). A cylindrical bottleneck (5) is arranged at the upper part of a cleaning bottle matched with the environmental protection blackboard eraser, with the diameter being 70 to 90 percent of the diameter of the cross section or the diagonal line of the eraser head (1); a cylindrical bottle body (6) is arranged at the lower part of the cleaning bottle, with the diameter being 2 to 5 times of the diameter of the bottleneck. The upper end and the lower end of the bottleneck (5) are all horn-shaped. When being used, the eraser head (1) is inserted into the bottle body (6) for cleaning, and is extruded when being drawn out of the bottleneck (5), so that excess moisture is extruded. Flying dust is avoided when the eraser head (1) containing a proper amount of moisture is used for wiping the blackboard, and thus the effects of environmental protection and sanitation are achieved.

Description

Environment-friendly dust-proof eraser and washer bottle thereof

One, technical field

The utility model relates to a kind of teaching aid.

Two, technical background

In recent years, along with science and technology and expanding economy, various educational technology equipments have been come into school classroom, as computer, projecting apparatus etc.Convenient, fast, advantages such as the information storage big, health that these educational technology equipments have, however, they can't replace traditional chalk and blackboard fully, in present most situations is that educational technology equipment and blackboard, chalk use simultaneously, and the blackboard eraser of prior art is to have installed and fixed a felt in an iron sheet lid, cause dust from flying when erasing the board, it has not only polluted air, healthy unfavorable to teachers and students, simultaneously, because educational technology equipment all belongs to precision instrument, the pollution of dust causes the fault even the damage of equipment easily.

Three, utility model content

The purpose of this utility model is blackboard eraser and the washer bottle thereof that a kind of cleaning, environmental protection, no dust pollution will be provided.

The utility model environment-friendly dust-proof eraser is formed by wiping head and handle, wipes head and makes with sponge, felt or other porous material; Handle is strip, wipes head and is fixed on the handle.

Do not run into blackboard for the finger of handle in use, the handle afterbody can be bent into serpentine.

Matching used with environment-friendly dust-proof eraser is washer bottle, its top is cylindrical bottleneck, and its diameter is for wiping a cross-sectional diameter or cornerwise 70%～90%, and the bottom is cylindrical bottle, its diameter is 2～5 times of bottleneck diameter, the flare of two ends up and down of bottleneck.

Adopt technique scheme, when needs erase the board, grasp the handle of environment-friendly dust-proof eraser, insert in the washer bottle that is filled with water wiping head, upper and lower pulling and pushing several times will be wiped head after cleaning and be extracted from washer bottle.Because it is little that the cross-sectional area of bottleneck is wiped the cross-sectional area of head, in the process that the wiping head is extracted from bottleneck, be squeezed, extrude too much moisture content, keep suitable moisture content, this wiping head that contains suitable moisture content can effectively prevent flying upward of dust when erasing the board.Because staff does not contact the wiping head, also do not contact sewage that clean to wipe head in addition, so it have sanitation and hygiene, environment friendly and pollution-free advantage.

Four, description of drawings

Fig. 1 is the front view of environment-friendly dust-proof eraser, adopts partial cutaway to show.

Fig. 2 is the vertical view of environment-friendly dust-proof eraser.

Fig. 3 is that environment-friendly dust-proof eraser inserts the structure chart when cleaning in the washer bottle.

Five, the specific embodiment

Below in conjunction with the drawings and the specific embodiments the utility model is further described.

In Fig. 1 and Fig. 2, environment-friendly dust-proof eraser by wipe 1 and handle 2 forms, handle 2 is strip, wipes 1 a usefulness sponge, felt or other porous material and makes, wiping 1 is fixed on the handle 2.The method that installs and fixes has multiple, can fasten with glue, and also available screw, pressing plate will be wiped 1 and be fixed on the handle 2.Illustrated in figures 1 and 2 is to adopt inserted fixing: a wiping hole 3 that is shaped on a rectangle (or circular, ellipse) at the head of handle 2, wipe a section of 1 and also correspondingly make rectangle (or circular, ellipse), the shape and size of its waist and wipe a hole 3 and work in coordination.Because sponge has bigger compressibility and elasticity, pull out from a wiping hole 3 as long as will wipe an end of 1 during installation, treat that it unfolds back rubbing head 1 and just be embedded on the handle 2.Inserted advantage is to wipe 1 to be convenient to change when damaging.

In Fig. 3, the Cleaning bottle top that is used for cleaning environment-friendly dust-proof eraser is columniform bottleneck 5, its diameter is for wiping 70%～90% of 1 cross-sectional diameter (when plane of structure when be circular) or diagonal (when cross section is during apart from shape), so that be squeezed during by bottleneck 5 wiping 1, squeeze and remove too much moisture content.The bottom of washer bottle is columniform bottle 6, and its diameter is 2～5 times of bottleneck 5 diameters, so that contain enough water.The upper/lower terminal flare of bottleneck 5 is so that play the guiding role when wiping 1 insertion and extracting.
