A small ionization chamber

Abstract

The invention discloses a small ionization chamber, comprising an outer shell, which is in a circular tube shape; a front end fixing mechanism is arranged at the front end of the outer shell; a collecting electrode and a high-voltage electrode are arranged in sequence inside the outer shell from the inside to the outside; the collecting electrode and the rear ends of the high-voltage electrode are supported and connected by an insulating isolation mechanism, the insulating isolation mechanism comprises a protective electrode, the protective electrode comprises an inner tube and an outer tube which are fixedly connected, the outer tube is fixedly connected to the rear end of the high-voltage electrode, and the inner tube is fixedly connected to the collecting electrode; the rear ends of the high-voltage electrode and the collecting electrode are both connected with conductive springs; the rear end of the outer shell is connected with a rear end fixing mechanism, the rear end fixing mechanism is used to fix a connecting wire, and two different terminal ends of the connecting wire are respectively connected with the conductive springs at the rear ends of the high-voltage electrode and the collecting electrode; the invention can make the ionization chamber simultaneously connected with the collecting electrode and the high-voltage electrode by only one connecting wire through a uniquely designed internal structure of the ionization chamber, so as to avoid the connecting wire from being tangled in an arc channel and reduce the difficulty of extracting the ionization chamber.
