Description

One can Combined blackboard eraser matching used with blackboard eraser auto-cleaner

Technical field

The utility model relates to blackboard eraser, and specifically one can Combined blackboard eraser matching used with blackboard eraser auto-cleaner.

Background technology

At present, the structure of the blackboard eraser used in classroom is fixing, non-dismountable each other, can not change.For this reason, Chinese patent CN201534440U discloses a kind of blackboard eraser, and it is at the outer sheathed wiper of sponge, and between sponge and wiper, is provided with one deck Polypropylence Sheet, by often changing wiper, to remove the chalk dust on wiper.The blackboard eraser of this structure in actual applications, a blackboard must be wiped and change a wiper, just can reach the object removing chalk dust on wiper, and time at school, because inconvenience changes wiper constantly, dust reclaims not thorough, dust reclaims all unsatisfactory, pollute teaching environment, cleaning effect is limited, fundamentally can't resolve the harm of dust to teacher's health of human body; Blackboard after wiping across still has some writing edges and is retained on blackboard, not good to the wiping effect of blackboard, affects students ' reading, greatly have impact on the efficiency of attending class, and manufactured size is not rigorous.In use also relatively random, particularly its clean aspect is also careless about.

Utility model content

On of the present utility model is for overcoming above-mentioned the deficiencies in the prior art, and provides a kind of size accurate, and interchangeability is strong, can Combined blackboard eraser matching used with blackboard eraser auto-cleaner.

The technical scheme realizing the utility model object is:

One can Combined blackboard eraser matching used with blackboard eraser auto-cleaner, comprise blackboard eraser body, unlike the prior art: blackboard eraser body by plate body and with plate body below the Sponge rabbeted form, the width of the connecting gear of its width and blackboard eraser auto-cleaner matches; The working face of Sponge is differential of the arc shape, and be coated with at Sponge the working cloth cover that one deck matches with it, working cloth cover is connected with plate body bottom is detachable by the square annular groove being arranged on both sides, plate body bottom, and plate body top is provided with groove.

Described working cloth cover is flexibly connected with plate body by nylon cable tie.

Described working cloth cover is for be made up of the blended material that absorption property is strong.

The utility model has the advantages that: size is accurate, interchangeability is strong, and cloth cover is once damage and can change easily, not only convenient but also economical.The most important thing is can enter in a kind of special cleaner for blackboard eraser and carry out cleaning, and, after cleaning, its working position will be coated with a kind of special cleaning agent, to blackboard eraser be drastically increased at the cleaning capacity to dust-free chalk writing like this, the blackboard after wiping can not only be made not stay any vestige, and can time wiping time clean, the hygienic conditions in classroom are greatly improved.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model blackboard eraser;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is blackboard eraser and the matching used fundamental diagram of cleaner.

In figure: 1. blackboard eraser 1-1. plate body 1-2. Sponge 1-3. working cloth cover 1-4. nylon cable tie 1-5. elongate recesses 2. cleaner 2-1. main driving motor 2-2. drive 2-3. feed well 2-4. dust remover motor 2-5. ash collecting box 2-6. centrifugal dust remover 2-7. power transmission shaft 2-8. cleaning agent 2-9. roller 2-10. pallet.

Detailed description of the invention

With reference to Fig. 1-2, the utility model Combined blackboard eraser 1 overlaps 1-3 and nylon cable tie 1-4 by plate body 1-1, Sponge 1-2, working cloth and forms, Sponge 1-2 embeds in the square inside casing of plate body 1 bottom, one deck working cloth cover 1-3 is coated with at Sponge 1-2, cloth cover 1-3 upper end is fixed on tightly by nylon cable tie 1-4 in the square annular groove of plate body 1 bottom, cloth cover 1-3 bottom surface is blackboard eraser working face, after repeated multiple times use, certain wearing and tearing can be caused to cloth cover 3, only nylon cable tie 1-4 need be taken away, change a new cloth and overlap.Also be provided with two the elongate recesses 1-5 matched with finger size at plate body 1-1 end face, groove 1-5 is when putting into cleaner and being clean by blackboard eraser, finger in insertion groove, can be taken conveniently, and decrease material usage, reduce production cost.

With reference to Fig. 3, this Combined blackboard eraser and cleaner with the use of time, after blackboard eraser 1 puts into the feed well 2-3 of cleaner 2 according to the direction of arrow, main driving motor 2-1 and dust remover motor 2-4 starts simultaneously, by drive by blackboard eraser 1 automatic capturing, enter Transfer pipe, drive power transmission shaft 2-7 motion for the relative rotation by worm and gear, blackboard eraser 1 is moved in parallel in direction from left to right.When above it moves to centrifugal dust remover 2-6, the working face bottom blackboard eraser 1 and centrifugal block for clutch use come in contact, so, be attached to dust on blackboard eraser 1 and be centrifuged and get rid of block and impact in multiple times and come off, finally drop in the ash collecting box 2-5 below centrifugal dust remover 2-6.When the dust of ash collecting box 2-5 reaches some, just easily ash collecting box 2-5 can be taken off, dust is cleared up in dustbin.Blackboard eraser 1 continues to move right; when blackboard eraser 1 moves to roller 2-9 place; working face bottom blackboard eraser 1 and roller 2-9 outer round surface come in contact; because roller 2-9 is in one to soak in cleaner special 2-8 also in the state rotated at a slow speed; and the protecting cloth of blackboard eraser 1 cover adopts blending absorbent material to make, and makes the working face bottom blackboard eraser 1 can adsorb cleaning agent 2-8 equably.When blackboard eraser 1 continues to move right to end, due to the object that it is not supported, blackboard eraser 1 falls in pallet 2-10 below automatically under gravity.In the moment that blackboard eraser 1 and main transmission depart from, whole Circuits System is also closed, and main driving motor 2-1 and dust remover motor 2-4 stops operating, and like this, whole cleaning just completes, and is about 20 seconds through putting into practice whole process.

Use mainly for dust-free chalk with this blackboard eraser matching used cleaner, volume is little, light, can place it in side, dais, classroom, be that two special blackboard wipings joined by a machine during complete use, after teacher writes, clean blackboard eraser in the delivery chute blackboard eraser of firm wiped clean blackboard being placed on cleaner, then from pallet, take out use from the blackboard eraser for subsequent use that previous step clean, so repetition alternate cycles work simultaneously, efficiency is high, does not affect normal teaching process.
