Fluid control assembly and fabrication method therefor

A fluid control assembly, comprising a body, wherein the body comprises a housing, a sealing member and a valve core, wherein the housing has an accommodating chamber, and at least a part of the valve core is located within the accommodating chamber, the housing comprises a first mounting main body with a mounting surface, and the first mounting main body is configured for mounting the body, the housing is provided with at least two passages and an accommodating groove which surrounds the passages, the passages penetrate through the mounting surface, and the accommodating groove extends from the mounting surface toward the interior of the first mounting main body;

• wherein the sealing member is provided with a plurality of first through holes, the first through holes correspond to and are in communication with the passages of the housing, the sealing member comprises a main body and a first outer extension part which are connected to one another, the first outer extension part is formed at an edge portion of the main body in a width direction of the main body, the first outer extension part protrudes from the main body in a height direction of the main body, and the first outer extension part forms a closed-loop protruding structure around each of the first through holes at one end of the first through holes;
• wherein at least a part of the main body is filled in the accommodating groove, at least a part of the first outer extension part is located on the outer side of the accommodating groove, and at least a part of the first outer extension part protrudes from the mounting surface, and the sealing member and the housing are formed in an integral structure,
• wherein the sealing member further has a first inner wall corresponding to the first through hole, the first outer extension part has a first inner side surface, a first outer side surface and a first joint surface connected between the first inner side surface and the first outer side surface, the first inner side surface and the first outer side surface are located on both sides of the first outer extension part in the transverse direction respectively,
• wherein the first joint surface is located at one end of the first inner side surface away from the main body in the height direction of the main body, the first inner side surface of the first outer extension part is a part of an inner wall surface of the first through hole, and the first joint surface is a curved surface,
• wherein, when the sealing member is in an uncompressed state in the height direction of the main body, the first outer extension part extends from the main body toward a center line of the first through hole in a direction oblique to the height direction of the main body.
