Abstract
The utility model relates to a dust sucking electromagnetic board brush. The left upper part in a casing is provided with a sweeping device, the right lower part is provided with an electromagnetic brush and an electric device, and the left side is provided with a power supply box. The handle type power supply box is held by a hand when the utility model is used, power supply is opened, chalk dust on the blackboard is rapidly and cleanly erased, and the chalk dust is sucked and collected in a dust sucking chamber simultaneously. The utility model has the advantages of rapid dust removal, good dust sucking effect, light weight and convenient use.
Description
The utility model relates to a kind of blackboard brush, exactly is a kind of dust suction electromagnetism scrubbing brush.
General blackboard brush commonly used all is to clean off a blackboard, and chalk dust flies upward around blackboard, and contaminated air influences the healthy of teacher and front-seat student, does not solve this class problem, and people have invented various electric dust absorption blackboard brush.As application number: 85202270, the applying date: 850614 " blackboard brush that has electric dust collector " is blackboard brush to be connected with dust catcher by connector realize dust-absorbing function, but heavy and use inconvenience.
The purpose of this utility model provide a kind of can the light again handy dust suction electromagnetism scrubbing brush of dust suction.
The purpose of this utility model is realized by following technical scheme.
The utility model is that the upper left side is provided with dust exhaust apparatus in the enclosure, and the lower right is provided with electromagnetic brush and electric device, and there is a power pack on the left side, it is characterized in that:
A, described electric device are that the commentaries on classics of motor is equipped with dust-absorbing fan in axle upper end, and the lower end is connected with the change-speed gearing of the interval electric supply installation that depends on motor, and motor is connected with power supply in the power pack by lead;
B, electromagnetic brush comprise the electromagnet in the pendulum mass, depend on the permanent magnet on it, are placed in thrust spring and hairbrush on the pendulum mass guide shaft, and guide rod one end connects hairbrush, and the other end passes spring and is connected in pendulum mass;
C, described dust exhaust apparatus comprise dust-absorbing fan and dust suction chamber, are provided with filter screen in the dust suction chamber, and there is an external exhaust outlet in its place ahead, also are provided with a baffle plate in the dust suction chamber.
During use, power-on, machine operation, make at interval electric supply installation work, by brush week period interval be powered at electromagnet, thereby make pendulum mass drive that hairbrush is done periodic swing at interval and dust on cleaning off a blackboard, simultaneously, machine operation drives dust-absorbing fan and rotates, and makes dust enter dust suction chamber by the dust-absorbing flue in the electromagnetic brush housing, retains in indoor after the filter screen filter.
The utility model has the advantages that dedusting speed is fast, pick-up performance is good, and light handy.
Fig. 1 is the utility model structural representation.
Fig. 2 is the electromagnetic brush structural representation.
By the following examples, in conjunction with the accompanying drawings, the utility model is done to describe further.
Embodiment:
(referring to Fig. 1,2) upper left side in shell 1 is provided with dust exhaust apparatus 2, and the lower right is provided with electromagnetic brush 3 and electric device 4, and there is a power pack 5 on the left side.Electric device 4 is that dust-absorbing fan 7 is equipped with in the armature spindle of motor 6 upper end, and the lower end is connected with the change-speed gearing 21 of the interval electric supply installation 8 that depends on motor, and motor 6 is connected by lead and power pack 5 interior power supplys.The housing of electromagnetic brush 3 is built-in with pendulum mass 9, and it is built-in with electromagnet 10, depends on permanent magnet 11 and electromagnet 10 mutual exclusions on it.Pass pendulum mass 9 and be fixed in cover one thrust spring on the guide shaft 12 on the shell, pendulum mass is slidably reciprocated along guide shaft.Guide rod 15 1 ends connect hairbrush 14, and the other end passes spring 16 and is connected in pendulum mass 9, the dust of hairbrush 14 on can cleaning off a blackboard under the pressure of spring 16.The housing of electromagnetic brush 3 is encapsulated in electromagnetic brush in it, makes the inner space have dust-absorbing flue of one's own, and dust enters dust suction chamber by dust-absorbing flue.Dust exhaust apparatus 2 comprises dust-absorbing fan 7 and dust suction chamber 17, establishes a filter screen in the dust suction chamber 17, and there is an external exhaust outlet 19 in its place ahead, also is provided with a plate washer 20 in the dust suction chamber and makes itself and dust suction chamber right panel be partitioned into entering-dust mouth.Described interval electric supply installation 8 is by the change-speed gearing 21 that is connected with motor 6, and rotating shaft 22 and two brushes 23 attached to it are formed, two brushes respectively and rotating shaft 22 normal open, the logical contact CONTACT WITH FRICTION that are provided with so that be interrupted period-power-supplying.Shell also is equipped with lift-over 24 at 1 the end, and side is equipped with power switch 25.
