Intelligent oscillograph with protecting and cleaning functions

Abstract

The invention relates to an intelligent oscillograph with protecting and cleaning functions, which comprises a main body, a handle, control buttons, and a display screen, the handle, the control buttons and the display screen are arranged on the main body, the intelligent oscillograph further comprises a protecting mechanism and a cleaning mechanism, the protecting mechanism comprises a protectingassembly and two driving assemblies, and the cleaning mechanism comprises a dust collection chamber, a dust removal tube, a dust removal cover, and two guiding assemblies. When the intelligent oscillograph with protecting and cleaning functions is not used, the display screen and the control buttons are protected by the protecting mechanism, so that the display screen and the control buttons areprevented from being exposed, consequently, the risk of the display screen being scratched or impacted is decreased, moreover, the probability of the control buttons being pressed by mistake is decreased, and therefore the practicability of the oscillograph is enhanced; in addition, foreign matters covering the surface of the display screen and the gaps of the control buttons, such as dust, can beadsorbed by the cleaning mechanism, consequently, the foreign matters are prevented from affecting the viewing of the display screen, and the foreign matters are also prevented from being accumulatedto shorten the service life of the control buttons.

Description

technical field [0001] The invention relates to the field of electronic detection equipment, in particular to an intelligent oscilloscope with protection and cleaning functions. Background technique [0002] An oscilloscope is an electronic measuring instrument with a wide range of uses. It can convert invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit a screen coated with fluorescent substances to produce tiny light spots. Under the action of the signal under test, the electron beam is like the tip of a pen, which can draw the change curve of the instantaneous value of the signal under test on the screen. It can be used to test various electric quantities, such as voltage, current, frequency, phase difference, amplitude modulation and so on. [0003] However, existing oscilloscopes still have som...

AI Technical Summary

Problems solved by technology

[0003] However, existing oscilloscopes still have some deficiencies during use. First, when the oscilloscope is not in use, the display screen and control buttons on the machine are exposed, which makes the display screen have the risk of being scratched or bumped, and The control buttons may be pressed by mistake, which makes the oscilloscope less practical; in addition, with the long-term use of the oscilloscope, the surface of the display screen and the gaps between the control buttons will be covered with dust and other impurities, which will not only affect the display screen. watch, it will also shorten the service life of the control buttons
