Abstract
The utility model relates to a teaching aid, particularly to a dust removing blackboard. The technical scheme includes that the dust removing blackboard comprises an annular frame and a plate arranged in the annular frame, wherein the annular frame comprises two symmetrical perpendicular edges and two horizontal parallel edges connected with the two perpendicular edges, a plurality of dust collection air ports are opened on the perpendicular edges and communicated through confluence channels, output ends of the confluence channels extend outside the annular frame, and a fan communicated with the confluence channels is arranged outside the annular frame. By means of the dust removing blackboard, dust generated in a wiping process can be removed.
Description
Technical field
The utility model relates to a kind of teaching aid, and particularly a kind of dust is got rid of blackboard.
Background technology
When being teaching, blackboard is used for presenting the plate body of writing, traditional blackboard is comprised of the frame of ring-type and the plate body of being located in frame, chalk is writing words or figure on blackboard, mainly rely on eraser when needing wiping, eraser can produce more dust in wiping process, can affect to classroom and student's health.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of can get rid of blackboard with the dust that the dust that produces in wiping process is got rid of.
For achieving the above object, the utility model provides following technical scheme: a kind of dust is got rid of blackboard, include the ring-type frame and be located at the interior plate body of ring-type frame, it is characterized in that: described ring-type frame includes the perpendicular edge of two symmetries and the horizontal parallel edges that is connected with two perpendicular edge, offer some dust suctions air ports on described perpendicular edge, each dust suction air port is communicated with by the busway, the output of busway extends to outside the ring-type frame, and the ring-type frame is provided with the blower fan that is communicated with the busway outward.
Adopt technique scheme, by the dust suction air port is set on perpendicular edge, and the dust suction air port is communicated with by the blower fan of busway with the outside, when blackboard wiping, dust can be inhaled in the dust suction air port, wind is not raised everywhere, prevents that the user from sucking too much dust, for classroom and student's health provides guarantee.
The utility model further is set to: plate body is provided with the brush body that be arranged in parallel with horizontal parallel edges, and this brush body can be done vertically to move back and forth along perpendicular edge.
Wherein, the perpendicular edge place is provided with guide rail, and guide rail is provided with gathering sill, and the both sides of brush body are respectively equipped with the guide pad adaptive with gathering sill.
Adopt technique scheme, the setting party of brush body to the wiping of blackboard, when the word on blackboard or picture needed whole wiped clean, this brush body moves back and forth along perpendicular edge just can complete this work fast, namely laborsaving, quick again.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
A kind of dust is as shown in Figure 1 got rid of blackboard, includes ring-type frame 1 and is located at the interior plate body 2 of ring-type frame 1, and ring-type frame 1 includes the perpendicular edge 11 of two symmetries and the horizontal parallel edges 12 that is connected with two perpendicular edge 11.Offer some dust suctions air port 3 on perpendicular edge 11, each dust suction air port 3 is communicated with by busway 4, and the output of busway 4 extends to outside ring-type frame 1, the outer blower fan 5 that is communicated with busway 4 that is provided with of ring-type frame 1.In such scheme, by dust suction air port 3 is set on perpendicular edge 11, and dust suction air port 3 is communicated with by the blower fan 5 of busway 4 with the outside, when blackboard wiping, dust can be inhaled in dust suction air port 3, wind is not raised everywhere, prevents that the user from sucking too much dust, for classroom and student's health provides guarantee.
In the utility model embodiment, plate body 2 is provided with the brush body 6 that be arranged in parallel with horizontal parallel edges 12, and this brush body 6 can be done vertically to move back and forth along perpendicular edge 11.Perpendicular edge 11 places are provided with guide rail 7, and guide rail 7 is provided with gathering sill 71, and the both sides of brush body 6 are respectively equipped with the guide pad 61 adaptive with gathering sill 71.The setting party of brush body 6 to the wiping of blackboard, when the word on blackboard or picture needed whole wiped clean, this brush body 6 moves back and forth along perpendicular edge 11 just can complete this work fast, namely laborsaving, quick again.Need to prove, brush body 6 is the guide rail guide groove with guide rail 7 and coordinates, and the guide groove on it or guide rail can be changed mutually.
Claims (3)
