Abstract

The utility model discloses a Millikan oil drop experiment spraying device, comprising an atomizing nozzle; the atomizing nozzle is communicated with an air compression pump by a solenoid valve and an air storage tank; a pressure sensor is arranged on the air storage tank, a signal output end of the pressure sensor is electrically connected with the signal input end of a singlechip, the control output end of the singlechip is respectively and electrically connected with the solenoid valve and the control input end of the air compression pump. The Millikan oil drop experiment spraying device has the advantages that the compression air pressure for spraying is consistent in each time owning to the adoption of the singlechip, the spraying time is determined by a starting time, so that the spraying time can be ensured to be the same at the same temperature in each time.

Description

The Millikan oil-drop experiment sprayer unit
Technical field
The utility model relates to Millikan oil-drop experiment equipment, especially relates to a kind of Millikan oil-drop experiment sprayer unit.
Background technology
The sprayer unit that uses in the Millikan oil-drop experiment at present is that an air bag connects atomizer, and air enters atomizer during extruding gasbag, and mist of oil sprays from nozzle.But used strength difference during the different people extruding gasbag, spray effect also can be different; And after using, oil that sprayer is put on the desk in it easily flows on the desk.
Summary of the invention
The Millikan oil-drop experiment sprayer unit that provides a kind of spray effect good is provided the utility model purpose.
For achieving the above object, the utility model can be taked following technical proposals:
Millikan oil-drop experiment sprayer unit described in the utility model comprises atomizer, and described atomizer is connected with air pressure pump by magnetic valve, air accumulator; Described air accumulator is provided with pressure sensor, and the signal output part of described pressure sensor is electrically connected with the signal input part of single-chip microcomputer, and the control output end of described single-chip microcomputer is electrically connected with the control input end of described magnetic valve, air pressure pump respectively.
The signal input part of described single-chip microcomputer is electrically connected with the signal output part of environment temperature sensor and keyboard respectively; The signal output part of single-chip microcomputer is electrically connected with the signal input part of display.
The utility model advantage is to have adopted single-chip microcomputer, can guarantee that the compressed air pressure of spraying all is consistent at every turn.Spray time was determined by the opening time, all was the same when same temperature so can guarantee the time of spraying at every turn.In addition for different temperature, the viscosity difference of oil, spray time can obtain revising.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, Millikan oil-drop experiment sprayer unit described in the utility model comprises atomizer 1, and described atomizer 1 is connected with air pressure pump 4 by magnetic valve 2, air accumulator 3; Described air accumulator 3 is provided with pressure sensor 5, and the signal output part of described pressure sensor 5 is electrically connected with the signal input part of single-chip microcomputer, and the control output end of described single-chip microcomputer is electrically connected with the control input end of described magnetic valve 2, air pressure pump 4 respectively; The signal input part of described single-chip microcomputer is electrically connected with the signal output part of environment temperature sensor and keyboard respectively; The signal output part of single-chip microcomputer is electrically connected with the signal input part of display.
