Static jump cylinder experiment instrument

Abstract

The invention provides a static jump cylinder experiment instrument, and belongs to college physics teaching experiment instruments. The static jump cylinder experiment instrument is composed of a metal cylinder, a transparent square box and a plastic comb. The static jump cylinder experiment instrument is characterized in that the metal cylinder is a cylinder body made of tin foil paper; the transparent square box is a cuboid body formed by enclosure of transparent plastic pieces; the width of the plastic comb is not less than that of the transparent square box; the metal cylinder is placed in the transparent square box to be sealed. The static jump cylinder experiment instrument is different from the prior art, and the difference lies in that an aluminum foil metal ball is replaced by the metal cylinder, metal electrode plates are replaced by the transparent plastic pieces, and an independent high-voltage direct current power is not needed. The static jump cylinder experiment instrument has the advantages of being small in size, convenient to carry and operate, easy to manufacture and obvious in effect, more educating functions can be increased in the process of popularization in teaching, and good technical assurance is provided for people for further theoretical research.

Description

technical field [0001] The patent of the present invention relates to the demonstration of a static jumping tube experimental instrument, which belongs to the field of university physics teaching experimental instruments. Background technique [0002] In college physics courses, static electricity is an important content, and the application of electrostatic induction is the content that everyone pays attention to. Over the years, in order to help students correctly understand this concept and apply electrostatic induction, some demonstration experiments have been set up in conjunction with teaching, such as electrostatic swinging ball experiment, electrostatic roller experiment, electrostatic jumping ball experiment, etc. Among them, the Chinese patent "Electrostatic Jumping Ball Demonstration Device" CN03277642 .X is to place light metal balls made of aluminum foil between the two metal plate electrodes, and the metal balls bounce back and forth between the two energized e...

AI Technical Summary

Problems solved by technology

Although the existing electrostatic jumping ball demonstration device has solved some needs to a certain extent, the experiment must be completed with an external high-voltage DC power supply, and students think that only metal electrode plates and metal balls will have the phenomenon of electrostatic jumping balls. It is inconvenient to move and limited, and there is a lack of new experiments to be explored by students who have the ability to learn. How to make an electrostatic jumping ball (tube) experimental instrument that is easy for students to self-made or improve, simple, effective, and does not require an external high-voltage DC power supply , this patent will solve this problem
