Abstract
The invention discloses a blackboard with an automatic dust removing function. The blackboard comprises an electric device and a transmission shaft which are arranged at the top of a plate surface, and a front bristle brush and a rear bristle brush which are arranged at the edge of the plate surface. The front bristle brush and the rear bristle brush are in slide connection with the plate surface. The electric device controls the front bristle brush and the rear bristle brush to slide through the transmission shaft. According to the blackboard with the automatic dust removing function, the electric device controls the transmission shaft to drive rollers of the front bristle brush and roller s of the rear bristle brush to move on slideways located on the upper side and the lower side of the plate surface, so that writing on the blackboard is removed, a connecting spring is arranged to guarantee that the two bristle brushes work synchronously in the same direction, and it is ensured that the blackboard is wiped clean; since integrated circuit control is adopted for the blackboard with the automatic dust removing function, consumption of electric energy is lowered while control coordination is guaranteed; and an automatic lock catch is arranged for improving the controllability of the bristle brushes and preventing raised dust caused by springback of the bristle brushes.
Description
Technical field
The invention belongs to instrument consumptive material field, it is related to a kind of teaching equipment, more particularly, to a kind of automatic dust-reducing blackboard.
Background technology
Blackboard is a kind of the most frequently used teaching equipment.Although being widely used now projector etc. to realize electronization religion
Learn, but, blackboard writing has irreplaceable effect in terms of vivid teaching.And, needed supporting using projector
Apparatus such as computer, price is more high, is poorly suited for economically underdeveloped area and promotes the use of.It is necessary to adopt when using blackboard
Write with chalk, traditional blackboard, during wiping chalk, can produce a large amount of dust, have a strong impact on academics and students
Healthy.And, traditional blackboard size, height etc. are fixing, using very inconvenient.Although having had now can be certainly
The report of the dynamic blackboard wiping, but due to complex structure, relatively costly, and wipe unclean, it is unfavorable for popularization and application.
In order to solve above-mentioned technical problem in prior art, develop a kind of dust-free blackboard, including blackboard body, described black
Plate body is flexible body, and described blackboard body head and the tail are closed, and described blackboard body is also associated with support, and black in head and the tail closing
The two ends of plate body are provided with rotating shaft, described blackboard body with the rotation of described rotating shaft and shuttling movement, described rotating shaft and first
Motor connection；Also include blackboard frame, described blackboard body is detachably connected with described blackboard frame by described support；Also include to
Few two swipe, described swipe is located at after described blackboard body, and a left side for the two ends of described swipe and described blackboard frame
The inner side on right both sides connects and leaves space between described swipe and described blackboard body, and, described swipe is connected with flexible knot
Structure, described stretching structure is connected with the second motor；The side of described blackboard frame is provided with control knob, described control knob and institute
State the first motor and/or the second motor connection and corresponding control program is set.
Above-mentioned prior art construction is complex, passes through two motor control swipe and stretching structure respectively, is also easy to produce control
System imbalance, and increase the consumption of electric energy.
Content of the invention
Present invention solves the technical problem that：In order to overcome the defect of prior art, obtain a kind of control integration, electric energy disappears
Consume low blackboard, the invention provides a kind of automatic dust-reducing blackboard.
Technical scheme：A kind of automatic dust-reducing blackboard, including the electric device located at plate face top and power transmission shaft, and located at plate
The preposition hairbrush at face edge and rearmounted hairbrush；Described preposition hairbrush and rearmounted hairbrush are slidably connected with plate face；Described electric device
Preposition hairbrush and rearmounted hairbrush is controlled to slide by power transmission shaft.
Preferably, the lower section of described plate face is provided with powder collecting tank.
Preferably, on the downside of described plate face, two ends are provided with powder disposable box.
Preferably, described powder disposable box at least 2.
Preferably, described preposition hairbrush and rearmounted hairbrush upper and lower end parts are provided with roller, and plate face correspondence position is provided with slideway.
Preferably, described plate face one end relative with preposition hairbrush and rearmounted hairbrush is provided with automatic locking.
Preferably, connected by connecting spring between described preposition hairbrush and rearmounted hairbrush.
Beneficial effect：(1) automatic dust-reducing blackboard of the present invention controls power transmission shaft to drive preposition hairbrush by electric device
Move on the slideway of plate face upper and lower sides with the roller of rearmounted hairbrush, remove the writing on blackboard, the setting of connecting spring ensures
Two hairbrush work simultaneously, in the same direction it is ensured that wiped clean；(2) automatic dust-reducing blackboard circuit of the present invention controls integration,
While ensureing to control coordination, reduce the consumption of electric energy；(3) automatic dust-reducing blackboard of the present invention passes through design lock automatically
Button, improves the controllability of hairbrush, prevents the resilience of hairbrush, cause airborne dust.
