End sealing head structure of liquid processor shell

The embodiment of the utility model relates to an end sealing head structure of a liquid processor shell. The end part of a pipe body of the end sealing head structure is formed into an inner ring groove matched with a filter element fixed head by stamping or rolling. The end sealing head structure of the liquid processor shell avoids the problems of liquid corrosion resistance destruction, false solder, solder skips and cold solder joint caused by welding another ring structure on the pipe body, therefore, the whole performance of a liquid processor is guaranteed; and simultaneously, the inner ring groove is formed by the mode of stamping or rolling without adopting an extra ring structure, therefore, the production cost of the liquid processor is reduced.
