Description
Technical field
The utility model relates to realia technical fields, and in particular to blackboard eraser.
Background technique
Blackboard eraser is essential tool on the dais of classroom, and blackboard eraser in use, can generate a large amount of chalk
End, although present chalk has been much dust-free chalk, when being only limitted to write, blackboard eraser also occurs reducing dust,
But the time has been grown and has still suffered from many chalk powders and overlay on blackboard eraser, or falls within the lower section of blackboard, cleaning is got up very unavoidably,
And it is easy pollution classroom environment, it is endangered to the health care belt of academics and students, and traditional blackboard wiping need to exert oneself in wiping
Pressing, laborious to use, each use will take again, inconvenient.
Utility model content
The task of the utility model is to provide blackboard eraser, automatic erasing and can suck dust when use, wiped clean, and
Dust pollution classroom environment can be prevented, in addition, blackboard eraser can also be adsorbed on blackboard, and adsorption capacity is adjustable, convenient
It takes.
The utility model is realized by following technical proposals:
Blackboard eraser, including blackboard eraser shell, and wiping disk, asepwirator pump, motor, adsorbent equipment, the electricity of setting inside the shell
Pond and switch button, the bottom surface wiped disk and be exposed to shell, asepwirator pump setting are being wiped behind disk, and the motor can drive wiping
Disc spins, battery, switch button, motor and asepwirator pump are connected into a circuit, and switch button is exposed to the side of shell, described
Adsorbent equipment includes permanent magnet, magnetic inductive block, adjusting rod and adjusting knob, and one end of adjusting rod passes through shell side and revolves with adjusting
Button is fixedly connected, and the other end is threadedly coupled with permanent magnet, and adjusting knob is rotatably connected with shell, and magnetic inductive block is fixed
It is on the shell and opposite with permanent magnet to enable blackboard eraser to be adsorbed on the blackboard of magnetic conduction, it can by rotation adjusting knob
The distance of permanent magnet and magnetic inductive block is adjusted, so as to adjust the adsorption capacity between magnetic inductive block and blackboard.
It is preferred that the adsorbent equipment further includes magnetic guiding frame, magnetic guiding frame is fixed on the permanent magnet, and the both ends of magnetic guiding frame
It is bent towards the magnetic inductive block, magnetic inductive block described in magnetic guiding frame obvolvent can be driven by rotating adjusting knob.
Compared to the prior art, the beneficial effects of the utility model are: combining by wiping disk and asepwirator pump, disk is wiped by motor
Rotation is driven to wipe the dust on blackboard, wiped clean and laborsaving, and sucked dust in blackboard eraser shell by asepwirator pump
Portion can prevent dust pollution classroom environment；Blackboard eraser can be made to finish in use by adsorbent equipment and directly adsorb in blackboard
On, it takes conveniently, and the size for adjusting adsorption capacity can be facilitated by adjusting knob, to be applicable in different blackboard and user.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model blackboard eraser；
Fig. 2 is the interior of shell structural schematic diagram of the utility model blackboard eraser.
Wherein: shell 1, wiping disk 2, asepwirator pump 3, motor 4, permanent magnet 51, magnetic inductive block 52, adjusting rod 53, adjusting knob 54,
Magnetic guiding frame 55, battery 6.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that saying that the specific embodiment of description is used only for explaining herein
The utility model is not used to limit the utility model.
As shown in Figure 1, 2, blackboard eraser, including blackboard eraser shell 1, and two wipings disks 2, air-breathing being arranged in shell 1
Pump 3, motor 4, adsorbent equipment, battery 6 and switch button, two wiping disks 2 are all exposed in the bottom surface of shell 1, and the setting of asepwirator pump 3 exists
It wipes behind disk 2, motor 4, which can drive, wipes the rotation of disk 2, and battery 6, switch button, motor 4 and asepwirator pump 3 are connected into a circuit,
Switch button is exposed to the side (switch button is not shown in the accompanying drawings) of shell 1, and adsorbent equipment includes permanent magnet 51, magnetic inductive block
52, adjusting rod 53 and adjusting knob 54, one end of adjusting rod 53 pass through 1 side of shell and are fixedly connected with adjusting knob 54, separately
One end is threadedly coupled with permanent magnet 51, and adjusting knob 54 is rotatably connected with shell 1, and magnetic inductive block 52 is fixed on shell
It is on 1 and opposite to enable blackboard eraser to be adsorbed on the blackboard of magnetic conduction with permanent magnet 51, it can by rotation adjusting knob 54
The distance of permanent magnet 51 and magnetic inductive block 52 is adjusted, so as to adjust the adsorption capacity between magnetic inductive block 52 and blackboard.Adsorbent equipment
It further include magnetic guiding frame 55, magnetic guiding frame 55 is fixed on permanent magnet 51, and the both ends of magnetic guiding frame 55 are bent towards magnetic inductive block 52, are passed through
Rotation adjusting knob 54 can drive 55 obvolvent magnetic inductive block of magnetic guiding frame, so that the leakage field of magnetic circuit be made to reduce, absorption property is more preferably.
In use, being combined by wiping disk 2 and asepwirator pump 3, wipes disk 2 and drives rotation to wipe the dust on blackboard by motor 4,
Wiped clean and laborsaving, and sucked dust inside blackboard eraser shell 1 by asepwirator pump 3, dust pollution classroom ring can be prevented
Border；Blackboard eraser can be made to finish in use by adsorbent equipment to directly adsorb on blackboard, taken conveniently, and pass through adjusting knob
54 can facilitate the size for adjusting adsorption capacity, to be applicable in different blackboard and user.
The preferred embodiment of the utility model is given in attached drawing.But the utility model can be with many different shapes
Formula is realized, however it is not limited to this specification described embodiment.On the contrary, purpose of providing these embodiments is makes to this reality
Understanding with novel disclosure is more thorough and comprehensive.
