Abstract

The utility model discloses a multifunctional dust-collection type blackboard eraser, which is composed of a dust collector (7) and a blackboard eraser (1), and is characterized in that dust collection holes (4) are formed in a support plate (2) of the blackboard eraser (1), the dust collection holes (4) are communicated with the dust collector (7) through a dust collection rigid tube (5) or a dust collection hose (6). Compared with prior art, the multifunctional dust-collection type blackboard eraser has the advantages that, the dust collection holes (4) are formed in the support plate (2), and the blackboard eraser (1) is communicated with the dust collector (7), so that dust can be effectively collected when people is erasing the blackboard; the blackboard eraser (1) is provided with the dust collection rigid tube (5), so that the handle of the blackboard eraser (1) is effectively prolonged, and the erasable range is greatly enlarged; the dust collector (7) is communicated, so that chalk dust can be more effectively cleared, and serious dust pollution to classroom environment caused by the chalk dust is greatly reduced. The multifunctional dust-collection type blackboard eraser can be widely applied to schools and other study occasions for erasing the blackboards or dedusting floors and the like.

Description

Multifunctional dust collecting formula blackboard eraser

Technical field

The utility model relates to a kind of blackboard eraser, particularly a kind of " Multifunctional dust collecting formula blackboard eraser ".

Technical background

At present, at school's extensive use or " blackboard " extensively sold on market mostly still " hard plate ", and the writing implement using is mainly still " chalk ".The main tool of removing letter written with chalk still or blackboard eraser.And extensively Brush type blackboard eraser just still be take as main mostly at the blackboard eraser of extensive use in sale or school in the market.The basic principle of its making is all on a harder oval or square supporting plate of the circles such as wooden or polymer, to be fixedly installed the soft things such as mane or felt to form.The major advantage of these blackboard erasers is: manufacture simple, with low cost, use more convenient, but the problem of its existence mainly contains two: the one, and can produce in use more dust and cause religion indoor air environment to pollute, the dust producing is easy to be inhaled into teachers and students' nasal cavity and affects the healthy of teacher and student, and especially teacher is injured particularly serious with the student who sits in front; The 2nd, handle is shorter, cause the corner of some blackboard to can not get effective wiping, sometimes have to use stool feet just can deal with problems, like this, will a lot of troubles and unsafe factor have been brought to teachers and students, when individual shorter pupil is on duty for the day, the phenomenons such as student's tumble injury that blackboard wiping causes also happen occasionally, thereby also very easily cause the dispute of the head of a family and school.For avoiding the generation of these phenomenons, some science-and-technology enterprise or scientific and technological fan also attempted a lot of more advanced settling mode and methods, someone has designed can be up and down or the blackboard moving left and right, and what have has also designed " liquid chalk " etc., but still not as people's will.Such as, how could more effectively remove the dust problem of chalk, the new wiping side problem of " liquid chalk " etc. also still need further to be solved.

Summary of the invention

The purpose of this utility model is to provide that a kind of manufacture is simple, dust collection capacity strong, use more convenient and robust " Multifunctional dust collecting formula blackboard eraser ".

The purpose of this utility model realizes by the following method: this blackboard eraser consists of dust catcher, blackboard eraser, in the supporting plate of blackboard eraser, is provided with air suction opening, and the air suction opening of blackboard eraser is communicated with formation by dust suction hard tube and hose with dust catcher.

For improving better the object of above-mentioned utility model, also can come in the following manner to be realized: between blackboard eraser and the hose of dust catcher, being provided with a hard tube length is the hard tube between 50 centimetres to 200 centimetres; One end of this hard tube is fixedly communicated with the rear other end with the air suction opening of blackboard eraser and is communicated with the hose of dust catcher; For improving wiping effect, rotation or swing-type electric electric brush can be set in blackboard eraser, this rotation or swing type hairbrush can be driven by micromachine, the wind drive that also can be produced by dust catcher.

The utility model " Multifunctional dust collecting formula blackboard eraser " is compared tool with existing technology and is had the following advantages: owing to being provided with through hole and blackboard eraser is connected with dust catcher on supporting plate, therefore can more effective dedusting when blackboard wiping; Owing to being provided with fixedly hard tube on blackboard eraser, therefore can make the handle of blackboard eraser obtain effective lengthening, greatly expanded erasable scope; Owing to being communicated with dust catcher, therefore can more effectively remove the powder of chalk, greatly reduced the serious dust pollution that chalk powder brings to classroom environment.

Accompanying drawing explanation

Fig. 1 is that master of the present utility model looks schematic diagram

Fig. 2 is the positive side cross-sectional schematic of the utility model wiping board

In figure, 1 blackboard eraser, 2 supporting plates, 3 hairbrush, 4 air suction openings, 5 dust suction hard tubes, 6 hoses, 7 dust catchers, 8 fixing seal devices.

With reference to the accompanying drawings embodiment of the present utility model is described.

The specific embodiment

In Fig. 1, one or more air suction openings 4 are set the supporting plate 2 of blackboard eraser 1 is interior, after being communicated with the upper end of dust suction hard tube 5, air suction opening 4 (or is directly communicated with flexible pipe 6, in figure, do not do to represent), again the lower end of dust suction hard tube 5 is communicated with the upper end of hose 6, and then the lower end of hose is communicated with dust catcher 7.In the situation that being directly communicated with air suction opening with hose 6, can lengthen separately the handle (not doing in figure to represent) of blackboard eraser 1.In order to strengthen pick-up performance and energy-saving and noise-reducing etc., the interface of each mouth of pipe should be fixed to encapsulation process by fixing seal device 8.Dust suction hard tube 5 and blackboard eraser handle can be made respectively to (in figure, not doing to represent) and dust suction hard tube 5 is dispensed.

In Fig. 2, for strengthening wiping effect, hairbrush 3 can be made as to rotation or swing type, available micromotor driving hairbrush rotation or swing, the rotation of wind drive hairbrush or the swing (not doing in figure to represent) that also can utilize dust catcher to produce.
