Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
The blackboard brush for having dust-absorbing function as shown in Figure 1, including：Housing 1, compresses elastomeric 3, swipe 4 and swipe plate
11, the housing 1 is interior to be equipped with grey chamber 2, and the bottom of housing 1 is equipped with elastic membrane 5, and elastic membrane 5 includes but not limited to be caoutchouc elasticity
Film, the bottom of housing 1 are connected with swipe plate 11 by compresses elastomeric 3, and the swipe plate 11 is equipped with several swipes 4, compresses bullet
Property body 3 and the swipe 4 be separately mounted to two offsides of swipe plate 11, be equipped with suction inlet 10 between the swipe 4；
The swipe plate 11 is equipped with the strut 13 of 1~4 in the side of compresses elastomeric 3, adjacent with strut 13 to be equipped with
The fixed pulley 9 of identical quantity, the free end of the strut 13 are connect with one end of drawstring 7, and the other end of drawstring 7 is connected to elasticity
On film 5, the drawstring 7 is installed with fixed pulley cooperation so that when strut 13 is close to housing 1, i.e., black with forcing in erasing blackboard
During scrubbing brush, drawstring 7 pulls out elastic membrane 5 so that the volume increase of grey chamber generates the negative pressure for sucking dust；
The suction inlet 10 passes through swipe plate 11 and elastic membrane 5 to be connected with grey chamber 2 by hose 61, and suction inlet 10 can also lead to
It crosses telescoping tube 62 to connect with grey chamber 2 across swipe plate 11 and elastic membrane 5, the hose 61 is equipped with Air blow check valve 12, described
Housing 1 is equipped with gas vent 14, is equipped with filtration core 15 and Air blow check valve 12 in the gas vent 14, best, filtration core 15 is set
Before the air inlet of Air blow check valve 12, so as to which dust is avoided to enter in check valve 12.
4 material of swipe is PVC sponges, and the effect of the erasing chalk ash of PVC sponges is good.
Gap between the swipe 4 is 4~15mm, and preferably, the gap between swipe 4 is 5~7mm, so as to
More swipe is installed, it also can be there are appropriate gap, so that the dust of erasing is entered in suction inlet 10.
Elastic skeleton 16 is embedded in the swipe 4, the length that elastic skeleton 16 is embedded in swipe is swipe length L's
It 0.5~0.8 times, so that keeping gap between swipe 4, it is also possible that swipe 4 has higher elasticity, is wiping
After dust, it can restore in time as former state.
The side wall of the housing 1 is equipped with movable plate 8 to be opened/closed, and sealing strip is equipped between the movable plate 8 and housing 1,
It can be opened movable plate 8 after a certain time, the chalk dust of grey intracavitary be poured out, the sealing being equipped with by the movable plate 8 being equipped with
Item can avoid in use, and gap of the dust between movable plate 8 and housing 1 leaks out.
The inside of the compresses elastomeric 3 is equipped with the support plate 17 being fixedly connected with housing 1, and fixed pulley 9 is consolidated by pulley spindle
Dingan County is on the support plate 17, the distance between to elastic membrane 5 when the width of the support plate 17 is just compressed equal to swipe plate 11,
So as to limit the decrement of compresses elastomeric 3.
Swipe 4 is removably mounted on swipe plate 11, so that swipe 4 is after a period of use, Neng Goufang
Just it replaces so that the use cost of blackboard brush is cheaper.
By being equipped with grey chamber in the object of blackboard brush, the swipe of blackboard brush is set on swipe plate, and pass through compression
Grey chamber is connect by elastomer with swipe plate, suction inlet is equipped between swipe, and suction inlet is connected with ash chamber, by drawstring and
Elastic membrane is connect by fixed pulley with the pillar on the swipe plate so as to the chalk on blackboard wiped when
It waits, by pressure blackboard brush of when erasing the board, gradually exerting oneself, so that compresses elastomeric is compressed, so that drawstring will
Elastic membrane pulls downward on, so that the volume increase of grey chamber so that grey chamber generates negative pressure, so as to be generated in erasing blackboard
Dust is drawn into grey intracavitary portion, after backwash is often carried out once or several times, by the swipe of blackboard brush with blackboard is of short duration detaches, so as to
Compresses elastomeric is resetted so that the volume of grey chamber reduces, and portion gas is extruded, at this point, due to the row of being separately mounted to
The effect of Air blow check valve in stomata and in hose so that gas can only enter from hose, discharge out of gas vent, follow successively
The above-mentioned action of ring so as to complete the cleaning to entire blackboard, and can greatly reduce the chalk dust raised during erasing blackboard, significantly
The amount of chalk dust is reduced, reduces its injury to erasing blackboard person；And it is this simple in structure, it is purely mechanic device, does not need to electronics
Equipment and battery, cheap, structure is reliable, greatly reduces secondary pollution (such as：Battery pollution), therefore the utility model has
There is very big practical value.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
