Abstract

The utility model relates to an eraser cleaner used for removing the dust on the blackboard eraser, which is composed of an oblong box body and a box cover. The edges of both sides of the box cover can be pushed and pulled in the slipway of the side wall of the box body. The case cover is provided with an opening which can clip the blackboard eraser, and toothed racks are arranged below the case cover. An elastic beat is arranged in the box body, and a beat bar is provided with an upward protrusion contacted with the toothed rack. The case cover is moved forward and backward to drive the toothed rack and the blackboard eraser to move, in order to make the elastic beat vibrate up and down to beat the blackboard eraser and achieve the dust-removing purpose. The utility model can prevent the dust form polluting the environment and can extend the service life of the blackboard eraser.

Description

Eraser cleaner

The utility model relates to a kind of cleaner of removing chalk dust on the blackboard eraser, is applicable to the occasion of using chalk teaching etc.

The cleaning of blackboard eraser is at present mostly finished by direct beating with to the mode that wall etc. is located to clash into, and causes dust to fly upward, and not only unhygienic but also unbecoming, the wearing and tearing to blackboard eraser are also bigger simultaneously.

The purpose of this utility model provides a kind of cleaner, and the dust removal process of blackboard eraser is finished in the closed box of cleaner, avoids the pollution of dust to environment, prolongs the service life of blackboard eraser.

The purpose of this utility model is achieved in that the blackboard eraser cleaner is made up of a rectangular box and case lid, and the both sides of the edge of case lid can be free to slide in the slideway of wall box, have on the case lid one with the identical opening of standard blackboard eraser physical dimension; A tooth bar is arranged below the case lid, and its length is identical with blackboard eraser.Have an elasticity to clap in the casing, have a projection that makes progress to contact with tooth bar on the dabber that elasticity is clapped, the size of projection and the between cog of tooth bar match.

During use the blackboard eraser that accumulates dust is snapped on the opening of case lid, by moving forward and backward case lid, constantly friction of the projection on tooth bar and the elastic rod, bump make the racket head up-down vibration, pat blackboard eraser, thereby with the dust abate in casing.

Seal of the present utility model has been avoided the pollution of dust to environment, and both evenly beaing that its elasticity is clapped can improve efficiency of dust collection, prolonged the service life of blackboard eraser again.

Below in conjunction with drawings and embodiments concrete structure of the present utility model and use thereof are described further.

Fig. 1 is the structural representation of the utility model embodiment 1;

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

Fig. 3 is the structural representation of embodiment 2;

Fig. 4 is the vertical view of Fig. 3.

The blackboard eraser cleaner is made up of a rectangular box 7 and case lid 1, and all around with being an integral body at the bottom of the case, its length is about three times of blackboard eraser to casing; Case lid 1 is an arm-tie that can be free to slide in the slideway of casing 7 sidewalls, its length is about four times of blackboard eraser length, have on the case lid one with the identical opening of standard blackboard eraser physical dimension, the position of opening half on the case lid length direction is to 3/4ths places, be fixed with a tooth bar 2 below the case lid 1, half place is arrived at 1/4th of case lid in the position of tooth bar 2.Have an elasticity to clap in the casing 7, it is racket head 5 that elasticity is clapped front end, and the middle part is a dabber 4, and the rear end is fixed in the casing; Have a projection that makes progress 3 to contact with tooth bar 2 on the dabber 4, the size of projection 3 and the between cog of tooth bar 2 match, and its position is at 1/3rd places of casing length; After being bent downwardly, dabber 4 middle parts upwards lift perk again, the felt face of the blackboard eraser 6 that racket head 5 is touched be stuck on the case lid.During use, long-pending blackboard eraser 6 felts that dust arranged are faced down be stuck in the opening of cleaner case lid 1, pull case lid 1 then, the tooth bar 2 that case lid adheres to below is also with case lid 1 motion, send living deformation with the contacted elasticity of tooth bar and change potential energy into, vertical tremor takes place, make racket head 5 beat, clash into blackboard eraser 6 repeatedly, the dust that gathers on the blackboard eraser 6 will be shaken and be fallen within the bottom of the case.Repeatedly the push-and-pull case lid 1, can reach the purpose of blackboard eraser 6 cleanings.Falling within dust at the bottom of the case can open case lid at any time and outwell.

Can also adorn a belt 8 of fixedlying connected with tooth bar 2 in the casing, on two turning cylinders 9 of belt 8 stalls in casing, one of them turning cylinder 9 is connected to the rocking handle 10 in the casing outside.Like this, case lid is seesawed, can reach the purpose of cleaning blackboard eraser equally by shaking rocking handle 10.
