According to the requirements of laws and regulations, front braking, rear braking and parking braking in a pneumatic braking system need independent energy storage devices, and in order to save space and cost, a partition plate 12 is welded in the middle of an air storage cylinder to form a double-cavity air storage cylinder in a double-cavity mode as shown in figure 1, so that two independent energy storage devices are formed. The double-cavity air cylinder needs to be immersed in the electrophoresis liquid 17 during electrophoresis, and after the electrophoresis liquid enters the air cylinder, air 18 is remained above the interior of the air cylinder, so that the electrophoresis of the region does not reach the standard. When the air reservoir leaves the electrophoresis cell after electrophoresis, a threaded hole in a water drain valve connector seat 16 arranged on the lower side wall of the air reservoir is generally used as a liquid outlet of electrophoresis liquid, and the electrophoresis liquid in the air reservoir flows out from the threaded hole. Therefore, how to avoid air residue above the inside of the air reservoir to improve the electrophoresis quality of the air reservoir is a technical problem that needs to be solved urgently by those skilled in the art.
