Abstract

The utility model relates to a dust collector teaching device, which comprises a dust collection bottom plate, a fan, a ventilation plate, a motor, a support plate, a power supply device and a lead; after the device is electrified, the fan rotates to generate suction, and garbage is adsorbed through the dust absorption holes of the dust absorption bottom plate, so that the teaching purpose is achieved. The utility model adsorbs the material through the dust absorption hole, and the adsorbed material is poured out through the detachable plate, so that the demonstration can be repeated; the ventilation strip structure of the ventilation plate can ensure that air below the fan is easily brought to the upper side and is not easy to flow back when the fan rotates, thereby enhancing the adsorption force of the dust collection hole; all the components are mechanically connected, and can be disassembled and assembled for many times.

Description

Dust collector teaching device

Technical Field

The invention relates to a teaching device, in particular to a dust collector teaching device.

Background

In order to improve the manual operation ability, the comprehension ability and the creativity of students, make the better use principle and the structure of understanding electrical apparatus of student, some dust catcher educational devices have been promoted on the market for realize the demonstration and the teaching of dust catcher theory of operation, at present, the dust catcher that is used for the teaching, it is rotatory mainly to utilize the motor to drive the fan, adsorbs the material, but general simple structure is coarse, the fan leaks outward, suction is more weak, dust absorption effect is not good.

Disclosure of Invention

The invention aims to provide a dust collector teaching device.

In order to solve the technical problems, the invention is realized by the following technical scheme:

the invention relates to a dust collector teaching device which comprises a dust collection bottom plate, a fan, a ventilation plate, a motor, a supporting plate, a power supply device and a wire, wherein the dust collection bottom plate comprises a dust collection hole and a detachable plate.

Furthermore, the vent plate is positioned between the fan and the motor and comprises a vent strip, a connecting hole and a clamping structure.

Further, the motor is connected with the supporting plate through a screw and a fixing structure.

Furthermore, the supporting plates and the vent plate, and the supporting plates and the dust collection bottom plate are mechanically connected through notches or communicating holes and clamping structures.

Further, the power supply unit is fixed to the support plate by a double-sided tape or a screw.

Furthermore, a lead is connected between the power supply device and the motor.

Furthermore, the dust suction holes in the dust suction bottom plate are circular, so that the suction force is more stable and uniform.

The invention has the advantages that: firstly, the fan rotates to form adsorption force, the adsorption hole adsorbs substances, and the adsorbed substances can be poured out through the detachable plate for repeated demonstration; the ventilation strip structure of the ventilation plate can ensure that air below the fan is easily brought to the upper side and does not easily flow back when the fan rotates, thereby enhancing the adsorption force of the dust collection hole; and thirdly, all the components are mechanically connected, and the device can be disassembled and assembled for many times.
