Section stretches out the opening of housing, for brushing blackboard.Being provided with a fagging between two rotating cylinders, fagging two ends are fixedly connected on housing
On, for supporting the wiping band flat segments stretching out shell nozzle.This invention carries out wiping by laying dust brush to the dust wiped on band, but
It is to solve the scattered problem of dust in wiping process.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of black board eraser with chalk-dust collector, solves
The problem that during blackboard wiping, chalk dust disperses.
For reaching above-mentioned purpose, this utility model by the following technical solutions:
A kind of black board eraser with chalk-dust collector, including housing and the Wiper plate being arranged in described housing, the described housing bag of cuboid
Including upper plate, lower plate, left plate, right panel and back plate, upper plate, lower plate, left plate and right panel edge are respectively provided with dust baffle, described dust
Baffle plate caves inward, and described lower plate is provided with projection away from one end of described back plate, and described Wiper plate upper end is remote with described upper plate
Hinged from one end of described back plate, described Wiper plate lower end is connected with described projection contacts, and described Wiper plate rear end face is with described
Being provided with elastomeric element between back plate, described lower plate arranges ash hole；Described Wiper plate arranges tourelle, described tourelle
Surface configuration has wiping body, described back plate to arrange dust removal unit, and after the interior upset mutually of described Wiper plate bottom, described wiping body is with described
Dust removal unit contacts.
Preferably, described dust removal unit is hairbrush.
Preferably, described tourelle for ellipse and is one.
Preferably, described tourelle is circular and for multiple, and described wiping body is one.
Preferably, described lower plate arranges limiting section, and described Wiper plate bottom contacts with described limiting section after inwardly overturning.
The beneficial effects of the utility model are:
A kind of black board eraser with chalk-dust collector of this utility model design, arranges dust gear at upper plate, lower plate, left plate and right panel edge
Plate, dust baffle is designed to flexible material, and dust baffle caves inward, do not affect the effect of wiping and also can be effective
Collect dust, the effective minimizing scattered problem of dust；Wiper plate one end is hinged with the front end of upper plate, and by elastomeric element
Thrusting action contacts with projection, and force pressing Wiper plate in wiping process, Wiper plate overturns in housing, now dust baffle
Being connected state with enclosure interior space, chalk dust can be slipped in housing；Wiper plate arranges tourelle, tourelle
Surface configuration has wiping body, back plate to arrange dust removal unit, and after the interior upset mutually of Wiper plate bottom, wiping body contacts with dust removal unit, passes through
Tourelle drives wiping body to rotate, and wiping body contacts with dust removal unit and relative movement occurs, and makes the chalk powder on wiping body
Dirt is eliminated and falls into lower plate；This utility model collection to the chalk dust that disperses in wiping environment, to the chalk on wiping body
Dust collection, it is achieved that the effect of multi-faceted dust, and when needing to clear up the dust in housing, elastomeric element pushing and withstanding Wiper plate
With projection contacts, prevent dust from spilling from Wiper plate edge, make dust pour out from ash hole.
It addition, dust removal unit is hairbrush, hairbrush can use the bristle of hard, is conducive to quickly clearing up the chalk on wiping body
Dust；Tourelle is oval and is one, and oval tourelle can design fixed part and rotation section, and rotation section is with solid
Determining to arrange roller between portion to be mutually rotatably assorted, this mechanism is simple and practical；Tourelle is circular and for multiple, many
The structure that individual round roller device can not wait with intended diameter, installs a wiping body, favorably on multiple round roller devices
In improving the flexibility ratio that wiping body rotates；Lower plate arranges limiting section, contacts with limiting section after the interior upset mutually of Wiper plate bottom, anti-
The excessive gap caused between Wiper plate and the housing change that only exerts a force is big, and chalk dust spills from gap.
To sum up, this utility model collects chalk dust from many aspects, and dust collecting effect is notable, and hinge structure has essence
Property feature and progress.
