The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.Following explanation is to adopt the mode that exemplifies, but protection domain of the present utility model should not be limited to this.
Present embodiment be by casing 15, be loaded on casing 15 upper ends case lid 16, take off dirt assembly, collection assembly of dust and Control Component and constitute.
Taking off the middle and upper part of dirt assembly apparatus working chamber in casing 15, is to constitute by taking off dirt vibration frame 4, vibrator 7, vibrator dust cover 5 and two vibration damping bars 3.Taking off dirt vibration frame 4 is bilevel frameworks, is used to place blackboard brush 10 in the frame-saw of its upper strata framework; Its lower floor's frame mounting on vibration damping bar 3, the frame-saw inner top surface device vibrator dust cover 5 of lower floor's framework.Vibrator dust cover 5 is box bodys of a lower aperture, its inner top surface device vibrator 7.Vibrator 7 is to get rid of piece 6 by motor and the off-centre of device on this motor shaft to constitute (vibrator 7 also can adopt electromagnetic vibrator, or other vibrating device, and this example adopts the eccentric motor that gets rid of piece of band), and upside-down mounting is at vibrator dust cover 5 inner top surfaces.Vibration damping bar 3 is (can adopt cross bar by the rope of interlude, also can adopt flexible strand, this example adopts flexible tendon rope) and install in this cable end and (can adopt an end to install, also can adopt two ends to install, this example employing two ends installation) spring 2 constitutes, the spring 2 of its end installs in the side of casing 15 inner chambers, and with rope stretch, exceptionally straight.
The bottom of collection assembly of dust device working chamber in casing 15 is to be made of the dust hopper 9 and the drawer 1 that gathers dust, and the upper end four limit devices of dust hopper 9 are in the side of casing 15 inner chambers, its lower device drawer 1 that gathers dust; The drawer 1 that gathers dust is shelved on the bottom face of working chamber in the casing 15.
In the control room 14 of Control Component device in casing 15, be (can adopt regular tap by gauge tap 11, also can adopt delay switch or time switch, this example adopts or time switch) and power supply 13 (can adopt battery or rechargeable battery, also can adopt battery, also can adopt the rectifier power supply, that is: 220 volts of alternating currents be changed into the direct current of 3-12 volt) constitute, connect power supply 13, gauge tap 11 and vibrator 7 with control line.
Blackboard brush of the present utility model is used takes off the dirt device automatically, both can directly be shelved on the dais, also can be fixed on the wall below the blackboard (at this moment, can install mounting bracket 17 respectively in left and right, the bottom of casing 15 back, install with convenient).
When having wiped blackboard and need use, earlier case lid 16 is opened (at this moment, case lid 16 is around the inside of casing 15 upper ends upset), then, the blackboard brush 10 of wiping blackboard is shelved in the frame-saw that takes off dirt vibration frame 4 upper strata frameworks, covers case lid 16 again, at this moment, flexible blackboard brush pressure pad 8 is pushed down the part of holding on blackboard brush 10 tops in case lid 16 inner chambers, has both avoided blackboard brush 10 to take off throwing in the dirt vibration frame 4 moving, can alleviate the vibration that it is delivered to case lid 16 again.Then, start-up control switch 11 (time switch), the off-centre of the driven by motor in the vibrator 7 on it is got rid of piece 6 rotations, produces vibration.This vibration passes to by vibrator dust cover 5 takes off dirt vibration frame 4, and then drives blackboard brush 10 vibrations, and the chalk dust that sticks on the blackboard brush 10 is removed.The chalk dust of removing, peripheral part directly falls into the following drawer 1 that gathers dust in the middle of it; Mid portion then drop on vibrator dust cover 5 above, and fall in the following drawer 1 that gathers dust by the edges above the vibrator dust cover 5 along with the carrying out of vibration; The chalk dust of peripheral part then drops in the following dust hopper 9, and by dust hopper 9 with its guiding below the drawer 1 that gathers dust in.When the timing of setting during to point, gauge tap 11 can automatic disconnections, cut off the electricity supply vibrator 7 quit work (when adopting delay switch, its operation principle is the same).
The chalk dust of in the drawer 1 that gathers dust, collecting more for a long time, the available handle that pulls drawer 1 end face that gathers dust, the drawer 1 that will gather dust is pulled out, and outwells then.Since the lower floor's framework that takes off dirt vibration frame 4 be device on vibration damping bar 3, be equivalent to be in suspended state, thereby, when taking off 4 vibrations of dirt vibration frame, the vibration that the spring 2 of vibration damping bar 3 ends can be decayed and pass over so greatly reduce the vibration of casing 15, makes complete machine operate steadily; Simultaneously, also greatly reduce the noise of complete machine operation.
Blackboard brush of the present utility model is used takes off the dirt device automatically, both applicable to primary school, junior middle school, also uses applicable to teaching in senior middle school even the university, also uses applicable to all kinds of training organizations.
