Abstract
The utility model relates to a porous absorbing type dustless blackboard which is composed of a panel, a bottom board and a frame, wherein, the panel is arranged on and is fixedly connected with a convex rib of the bottom board through the frame. Both side edges and the lower edge of the convex rib are provided with an air channel which is provided with an air inlet communicated with a cavity between the panel and the bottom board; an air outlet at one side of the air channel is communicated with a dust collector; micropores are uniformly distributed on the entire panel. When the utility model is used, the dust collector is started, writing dust enters the cavity from the micropores of the board surface, and then the dust enters the air channel with air flow through the air inlet and is finally absorbed into a powder storing bag of the dust collector. The utility model has the advantages of simple structure, low manufacture cost, convenient use and favorable dust absorbing effect, and can effectively prevent dust from polluting teaching environment.
Description
The utility model belongs to a kind of blackboard, and the teaching blackboard of sucking chalk powder device is particularly arranged.
The dust of writing on the blackboard is the old problem that influences the teaching environment health, although along with the electronic teaching mode has appearred in scientific and technological progress, but high and other reason owing to equipment cost, can't popularize at present, promote, most schools still still continue to use old-fashioned traditional blackboard, and blackboard is write dust has become a difficult problem that diminishes the healthy urgent need solution of vast Faculty and Students.
The purpose of this utility model is to provide a kind of no dust blackboard for education that can improve teaching environment at above situation.
Technical solution of the present utility model is: this blackboard is made up of panel, base plate and frame, the base plate periphery has fin, be provided with the air channel along dual-side in the fin and bottom, be furnished with air inlet on the air channel, air inlet communicates with cavity between panel and the base plate, panel is arranged on the base plate fin, the uniform micropore of whole front panel, and micropore communicates with air inlet with cavity between the base plate through panel.One side of above-mentioned base plate fin is provided with the air channel air outlet, and air outlet communicates with a dust exhaust apparatus, and base plate is fixedlyed connected by frame with panel.
During use, start dust exhaust apparatus, write dust slave plate face micropore and enter cavity between panel and the base plate, then enter the air channel through air inlet, be inhaled into the storage flour bag of dust exhaust apparatus at last with air-flow.
This blackboard for education is simple in structure, cost of manufacture is low, and pick-up performance is good, can effectively prevent the dust pollution teaching environment, is a kind of new teaching blackboard that is worthy to be popularized.
Further describe the utility model below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A-A profile.
Wherein: 1, frame 2, pillar 3, micropore 4, panel 5, dust exhaust apparatus 6, base plate 7, fin 8, air channel 9, air inlet 10, air outlet 11, dust filter unit 12, switch 13, blower fan 14, gauze 15, sealing strip
With reference to accompanying drawing, blackboard for education is made up of panel 4, base plate 6 and frame 1, and panel places on the base plate fin 7, and is fixedly connected by frame 1, and the junction periphery is equipped with sealing strip 15, and sealing strip can prevent that air-flow from entering in the blackboard cavity from periphery and form short circuit.Micropore 3 is at interval, is staggered on panel, and its diameter is advisable with 1～2mm, and dust can evenly enter cavity between panel and the base plate with air-flow like this, enters the air channel through air inlet 9 again, and pick-up performance is good.Be provided with some pillars 2 in the cavity between panel and base plate,, be convenient to write with support panel.
