Channel-separating structure and method for manufacturing a channel-separating structure

A channel-separating structure configured to be mounted on a top portion of a filter core;

• the channel-separating structure comprising:
• a top cap portion comprising
• a cooperating tube comprising
• a cooperating hole disposed inside the cooperating tube and formed through the top cap portion from top to bottom;
• and
• a connecting section disposed at a bottom portion of the cooperating tube;
• an assembling wall connected to the cooperating tube, being annular, and disposed at a bottom side of the top cap portion;
• the channel-separating structure mounted to the filter core through the assembling wall;
• a channel-separating portion disposed inside the cooperating hole of the cooperating tube and comprising
• a central tube mounted through the cooperating hole of the cooperating tube and comprising
• a central channel disposed inside the central tube;
• a connecting seat mounted at the outer side of the central tube, abutting and connected to the connecting section of the cooperating tube;
• the connecting seat comprising
• multiple through holes formed through the connecting seat from top to bottom;
• multiple ribs disposed at an outer side of the central tube and connected to the connecting seat;
• a gap located between an external edge of each one of the multiple ribs and an inner wall surrounding the cooperating hole;
• and
• a peripheral channel formed between the central tube and the cooperating tube and fluidly communicating with the multiple through holes.
