Description
Technical field
The technological improvement of teaching aid is the utility model is related to, more particularly to a kind of dust absorption blackboard eraser.
Background technology
Blackboard eraser is a kind of teaching aid, no matter in traditional teaching mode, or the modern multimedia teaching mould in rapid Optimum
Under formula, traditional instruction is carried out using blackboard, is all that teacher carries out emphasis explanation, Difficulty Analysis, logic putting in order etc. to the content of courses
Important carrier.But it is erasable due to being needed during traditional instruction repeatedly, and traditional blackboard eraser can only erasing out handwriting not
Discrete aerial dust can be absorbed, injury of the chalk dust to application on human skin and respiratory tract is bigger.
In view of the above-mentioned problems, providing a kind of new blackboard eraser, automatic absorption can be wiped when blackboard eraser use
Dust.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dust absorption blackboard eraser, can be used in blackboard eraser
When automatic absorption wipe dust.
To reach above-mentioned purpose, the technical solution of the utility model is a kind of dust absorption blackboard eraser, including base connection hair
Brush, base are externally connected to housing, it is characterised in that：Air suction opening, air suction opening connection are provided between described base and hairbrush
To the inside of base；Chassis interior is provided with dust sucting motor, dust sucting motor connection dust box.
Described base is provided with sensing unit, sensing unit control dust sucting motor work.
Described sensing unit is arranged on the both sides of base.
It is dust sucting motor, sensing unit power supply that described base, which is provided with lithium battery,.
Described sensing unit is that microcontroller connects pressure sensor.
Described dust sucting motor includes motor connection fan blade.
The profile of described housing is mouse structure, and the middle of housing is provided with the recessed air purge hole of a row.
A kind of dust absorption blackboard eraser, due to using above-mentioned structure, the utility model, it can be good at absorbing dust, relatively
The comparison that writing erasing is wiped in traditional blackboard is clean.Compact structure is simple simultaneously, easy to operation.

Embodiment
The utility model includes blackboard eraser base 1, housing 2 and hairbrush 3, and hairbrush 3 is connected to blackboard eraser base 1, housing 2 and bottom
There are dust sucting motor 6, lithium battery 8, sensing unit 9 between seat 1.
Dust sucting motor is mainly made up of motor and fan blade, and motor runs at high speed after energization, around produces extremely strong suction
And pressure, in the presence of suction and pressure, air is discharged at a high speed and the air of the vacuum part of fan blade front end is constantly mended
The air being charged into fan blade, its internal instantaneous vacuum of generation, and external atmosphere pressure is caused to form Negative Pressure Difference, when hairbrush sweeps into powder
Air suction opening 5 during dirt by base in the presence of this pressure difference can be separated dust and air, and air is from the upper end of housing
Discharge, dust are stayed in the dust box 7 of inside.
The inside of blackboard eraser employs lithium battery 8, and lithium battery 8 has high storage energy density, can store more energy
Amount.Service life is grown, and can reach more than 6 years.Possess high power and bear rate, can be with the Acceleration of starting of high intensity.Self-discharge rate is low,
Usage time length after fully charged.
Base 1 each side has a sensing unit 9, has pressure sensor and microcontroller group in sensing unit 9
Into, when human hand is picked up in a flash, pressure sensor collect signal be transmitted to microcontroller will automatic start lithium battery to inhaling
Dirt region provides power supply.
A dust box 7 is placed among dust sucting motor 6 and lithium battery 8, for absorbing chalk dust, dust box can be from base
Remove, for the chalk dust inside clearing up in time.
For blackboard eraser housing 2 we employ external form similar to mouse, so take up pleasant convenience.Housing
Middle have the recessed aperture of a row be used for exclude air.It is nested between housing 2 and base 1 to be connected, can individually it pull down,
Cleaning dust in time.
Specifically as Figure 1-3, the utility model includes the connection hairbrush 3 of base 1, and base 1 is externally connected to housing 2,
It is characterized in that：Air suction opening 5 is provided between described base 1 and hairbrush 3, air suction opening 5 is connected to the inside of base 1；In base 1
Portion is provided with dust sucting motor 6, and dust sucting motor 6 connects dust box 7.Dust sucting motor 6 includes motor connection fan blade.
Base 1 is provided with sensing unit 9, and sensing unit 9 controls dust sucting motor 6 to work.Sensing unit 9 is arranged on base 1
Both sides, sensing unit 9 be microcontroller connect pressure sensor.It is dust sucting motor 6, sense that base 1, which is provided with lithium battery 8, simultaneously
Unit 9 is answered to power.
The profile of housing 2 is mouse structure, and the middle of housing 2 is provided with the recessed air purge hole 4 of a row.
When people picks up blackboard eraser, because human hand touches sensing unit 9, the pressure sensor in sensing unit 9
Collect signal and be transmitted to microcontroller and allow lithium battery 8 to provide power supply to the motor in suction area 6 automatically, allow suction area 6 to open
Beginning work.
Drive the fan blade being connected with it to rotate at a high speed when the motor in suction area 6 starts to run at high speed, make inside it
Negative Pressure Difference is generated with the external world.When dust is swept into air suction opening 5 by hairbrush, because the effect dust of Negative Pressure Difference can be with air point
From air is discharged by air above tap 4, and dust has been left in dust box 7.
After blackboard eraser uses a period of time, because housing 2 and blackboard eraser base 1 nest together, we can be with
They are separated, then takes out dust box 7, the dust of the inside is cleared up, is then placed back into, then by the He of housing 2
Blackboard eraser base 1 is nested up.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the various improvement of technical solutions of the utility model progress are employed, or not improved directly application
In other occasions, within the scope of protection of the utility model.
