Description
Technical field
The utility model relates to teaching equipment fields, more particularly to a kind of mechanical dust-collecting type heteropleural transfer blackboard eraser.
Background technique
In China Today, chalk is still teachers' instruction indispensability tool, and almost all of teacher is using traditional chalk
It attends class, and the harm as caused by the dust of chalk is very important.Chalk is made of calcium carbonate calcium sulfate, and teacher is when using chalk
A large amount of chalk dust can be generated.Since dust cannot disperse as early as possible, floats in air, endanger the health of teachers and students.Meanwhile
The manufacture and use of chalk can also cause many problem of environmental pollutions, therefore design that collect the blackboard eraser of dust be urgent
Demand.
Based on the above situation, nowadays occur large quantities of dust-removing blackboard erasers, such as electric blackboard eraser, electrostatic precipitation in the market
Blackboard eraser etc..But it needs battery consumption energy in turn result in " battery pollution ", causes more serious harm to bad border, and
Required higher cost.And by specifically used its collecting effect of discovery and bad, principle is using wind-force generation negative pressure, in turn
Achieve the purpose that absorb dust.Since its negative pressure is smaller so mobile phone effect and bad.
Existing blackboard eraser, it is unfavorable with the receipts for completing dust in the case where the energy such as battery using special mechanical structure
Collection, but since its dust collect plant does not have reasonable locking device, dust is fallen in dust-collecting box to the process for reusing blackboard eraser
In, it is easy secondary trickle down on desktop or ground.And handle outstanding needs to use two hands when to erase the board, and is not easy to wipe
The simple operations of blackboard.

The handle 1 at 16 top of shell contacts, and lower fixed wheel is fixedly connected with connecting plate lower edge, and the first rotary shaft 4 passes through the company of rotating mechanism 3
Fishplate bar, both ends extend to 16 side wall of shell；Lower fixed wheel is fixedly connected with the first bar of three bar rotating mechanisms 5, and the second rotary shaft 6 passes through
Three bar rotating mechanisms, 5 center, both ends extend to 16 side wall of shell, and the second bar and third bar of three bar rotating mechanisms 5 are each passed through
16 bottom of shell；The operating mechanism includes sliver 13, brush 14, fixed gear 12, moving gear 10 and brush support rod 11；It is described
The second bar and third bar of three bar rotating mechanisms 5 are each passed through 16 bottom of shell, are separately connected a sliver 13 and a fixed gear 12,
Brush support rod 11 is fixed by the hanging hole that 16 bottom of shell is extended, and brush 14 is placed on the brush support rod 11
On, a moving gear 10 is respectively set in 14 two sides of brush in brush support rod 11, with the second bar for being set to three bar rotating mechanisms 5 and
Fixed gear 12 on third bar cooperates relative motion by gear；The detachable dust-collecting box 7 is set along 16 bottom of shell, one edge
It sets, and the opening of detachable dust-collecting box 7, from 16 bottom of shell towards 16 outside of shell, the opening of detachable dust-collecting box 7 passes through thin
Film plastics 15 are closed；It is in the baffle 9 of specified angle from the opening peripheral edge of detachable dust-collecting box 7 setting one and 16 bottom of shell,
In the space that brush 14 is located at baffle 9 and 16 bottom of shell is formed.Wherein, the structure of hanging hole is as shown in Figure 4.
Wherein, detachable dust-collecting box 7 is fixed on 16 bottom of shell by way of clamping or screw connection, removable to realize
Unload the detachable of dust-collecting box 7.
Wherein, the plastic film 15 of the opening setting of detachable dust-collecting box 7 is contacted with brush 14.
Wherein, plastic film 15 is in rectangular shape, the open edge for being fixed on detachable dust-collecting box 7 on one side of long side, brush
Son 14 opens plastic film 15 when rolling.As shown in Figure 3.
Wherein, baffle 9 is elastic material.
When specifically used, when erasing the board (outside paper) when to the left, handle is moved to left, and is held part handle 1 and is slided to the left, revolves simultaneously
The upper roller of rotation mechanism 3 is moved to the left, the connecting plate of rotating mechanism 3 and lower the fixed wheel (paper to the right under the action of the first rotation 4
It is interior) it is mobile, after and drag the first bar of three bar rotating mechanisms 5, so that it is rotated by a certain angle (into paper) clockwise, by second
Bar is released, and the fixed gear 12 and sliver 13 that the second bar is connected contact blackboard surface (idler wheel and sliver are in same plane) therewith, is opened
Beginning erases the board.
It by the effect of the gear teeth between moving gear 10 and fixed gear 12, rotates moving gear 10 under mobile power, moves
Gear 10 is fixed in brush support rod 11, and the rotation of moving gear 10 drives the rotation of brush support rod 11, to drive brush
Dust is swept into internal detachable dust accumulation box 7 by 14 rotation.Due to brush 14 rotation but also detachable dust-collecting box 7 it is thin
The sealing of film plastics 15 is opened, and dust is allowed to can smoothly enter into detachable dust-collecting box 7.Dust on blackboard passes through the wiping of sliver 13
It wipes, is detached from blackboard falls downward, falls on baffle 9, and slid in detachable dust accumulation box 7 along baffle 9.
When wiping blackboard to the right, left side sliver and idler wheel stretch out, with same method dedusting and dust.
When wiping the blackboard of different location, when erasing the board to the left, 5 right arm of component is stretched out so that right-hand wheel and sliver are stretched
It out and then wipes dust and wheel is allowed to rotate, convert the kinetic energy moved left and right to by gear the kinetic energy of brush rotation, so that
It can help dust to fall into internal dust-collecting box, when erasing the board to the right similarly.No matter wiping process or blackboard eraser placement process, dust
All largely outer it will not raise or leak.
It is different from the prior art, the mechanical dust-collecting type heteropleural transfer blackboard eraser of the utility model in dust accumulation structure by adding
The box of dress storage dust converts the kinetic energy of left and right erasing dust to the kinetic energy of brush rotation, recycles the rotation of brush will
Dust is swept into dust accumulation box, this dust accumulation box is detachable, convenient for dust is recycled secondary use；Handle outstanding is hidden into simultaneously black
Blackboard eraser two sides, operation comfort enhancing similar with using traditional blackboard to wipe.The utility model using machine driving reach wiping it is black
Plate simultaneously can be with the purpose of dedusting, and environmentally friendly entirely without energy consumption, required cost is relatively low, and structure is simply convenient for safeguarding.
The foregoing is merely the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
It is equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, directly or indirectly uses
In other related technical areas, it is also included in the patent protection scope of the utility model.
