Abstract

The utility model relates to an automatic dry cleaning machine for blackboard erasers used in schools generally, which is skillfully composed of a beater and an impeller driven by a motor, a shelf, a foam cushion, a partition board, a case body, etc. for realizing automatic dry cleaning. When blackboard erasers dried and cleaned by the utility model are used for erasing blackboards, chalk dust can not fly all around. Simultaneously, the secondary pollution of chalk dust can not occur during dry cleaning process. Dry cleaning is quick and convenient and can be carried out frequently and repeatedly. Thus, the air pollution caused by a large amount of chalk dust in a classroom is reduced, and indoor environment is improved and is beneficial to human health.

Description

The automatic blackboard eraser dry cleaner

Affiliated technical field

Thereby relating to, the utility model a kind ofly can carry out automated manner dry-cleaning alleviating " the automatic blackboard eraser dry cleaner " that chalk dust disperses to the blackboard eraser that generally uses now.

Background technology

At present, the large, medium and small the inside of China, " blackboard+chalk " pattern remain teaching give lessons in order to carry out the main mode that literary composition, figure transmit, almost all can be write many words on the blackboard in each class, local then or all wiped successively again, and bring a large amount of chalk dusts to waft because of erasing the board in the classroom, pollute room air, harm teachers and students health.

People had once developed " ash-collecting blackboard eraser " miscellaneous, as electric dust absorption formula, electrostatic precipitation formula etc., but eventually because of price height, weak effect, be not durable and do not have a using value.

The somebody has invented automatic dust absorption formula blackboard or self-propelled is wiped first-class main equipment, but because high price is extremely difficult universal.The blank that useful again ink is write, all-electronin display type blackboard, full-computerized blackboard for education though come out, from spreading to each classroom, are still needed and are waited for very long very long time.

Summary of the invention

The purpose of this utility model provides a kind of novelty " automatic blackboard eraser dry cleaner ", it is neither changed blackboard and is not also changed blackboard eraser, just provide automatic dry-cleaning at any time to blackboard eraser, allow the blackboard eraser surface remain good suction powdery attitude, just do not have the situation that the chalk dust houseful wafts when erasing the board so, thereby avoided the air pollution of wafting and causing because of chalk dust.

For assorted petty blackboard eraser only should dry-clean, can not the water braying? the washing blackboard eraser not only is difficult to dry, and is more that felt can harden behind the Qinshui, rotten and scrap very soon.

The technical scheme that the utility model solution is dry-cleaned this technical problem automatically and adopted is: dividing plate with holes is set in the barrel shape container, the lower partition is provided with motor and impeller, the foam filter bed is set on the dividing plate, place special-purpose shelf on the filter bed, dividing plate top is provided with electronic beater, beater is made up of the connection support, anchorage bar and the beating hammer that are connected on the motor reel, special-purpose shelf is frame structure and is with spacing block, container top is provided with retainer, and retainer is made up of locking key, spring, brake rubber block and shell.

Blackboard eraser is placed in the special-purpose shelf, allows beater that the blackboard eraser that is filled chalk dust is patted continuously, be in because of beating in the environment of relative sealing and carry out, prevented chalk dust generation secondary pollution.The impeller that the container internal cause is rotated at a high speed and produce " negative pressure " forms windstream, and air-flow carries dust that shake falls by wet filter bed, and wet filter bed stops chalk dust and adsorb that the air after the filter turns back to outside the container by steam vent.Extract immediately after wet filter bed washes and to use repeatedly.

For blackboard eraser is " dry-cleaning ".Filter bed for the carrying chalk dust is " washing ".Do directly flying upward of dust when both having avoided erasing the board like this, the flying upward indirectly of dust when also having avoided handling blackboard eraser used blackboard after the dry-cleaning to wipe to erase the board and just can not occurred the circumstances that chalk dust wafts everywhere.

Blackboard eraser just in use all can carry out dry-cleaning so easily and fast at any time, improves room air clean level, the raising teachers and students general level of the health thereby be of value to.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of embodiment.Left-half is an outline drawing, and right half part is a profile.Among the figure: 1-locking key, 2-spring, 3-button shell, 4-brake rubber block, the 5-arresting disc, 6 loam cakes, 7-casing, the 8-blackboard eraser, 9-felt, 10-shelf assembly, 11-beater assembly, 12-foam filter bed, 13-suction hole, the porose dividing plate of 14-, 15-motor, 16-impeller, the 17-rotating shaft, the 18-steam vent, the 19-power supply links mouth and switch assembly.

Fig. 2 is special-purpose shelf assembly structure schematic diagram.The 20-spacing block, the 21-framework junction part.The effect of spacing block is to allow shelf and wet foam filter bed keep a determining deviation, does not make felt sticking wet.

Fig. 3 is a beater assembly structure schematic diagram.22-connects support, the 23-anchorage bar, and 24-pats hammer.Pat hammer and be the open circles disk shape, made with elastomeric material.

The specific embodiment

Connect civil power by power supply connector and switch assembly (19), open switch again, motor (15) just high speed rotating gets up, the rotation of impeller (16), dividing plate cavity of resorption air is displaced from steam vent (18), the cavity of resorption of porose dividing plate this moment (14) produces negative pressure, forces to suck from air entry (13) air of filter bed (12) top.And at this moment beater is successively patted the blackboard eraser (8) in the shelf (10) under rotating shaft drives, the chalk dust that beating falls is just along with windstream flows downward, chalk dust is intercepted by moistening filter bed and adsorbs, and the air that flows through after the suction hole becomes pure air then, and is indoor from being returned to after steam vent (18) is displaced at last.Shut power supply, press locking key, arresting disc only stops motor rapidly under the brake rubber block compacting, opens loam cake (6), takes out blackboard eraser, blackboard eraser has at this moment obtained dry-cleaning.

Continue to use and can put back to original position after filter bed washed, extracts immediately.

Wipe with the blackboard after " dry-cleaning " and to erase the board just as blackboard eraser is repaired sth. old and made it as good as new, rely on the good suction powder effect of felt to make that chalk dust wafts when erasing the board no longer everywhere.

Claims

1. automatic blackboard eraser dry cleaner that energy is dry-cleaned automatically to blackboard eraser, it is characterized in that: dividing plate with holes is set in the barrel shape container, the lower partition is provided with motor and impeller, the foam filter bed is set on the dividing plate, place special-purpose shelf on the filter bed, dividing plate top is provided with electronic beater, beater is made up of the connection support, anchorage bar and the beating hammer that are connected on the motor reel, special-purpose shelf is frame structure and is with spacing block, container top is provided with retainer, and retainer is made up of locking key, spring, brake rubber block and shell.
