[0049] Specifically, the first plate 11 and the second plate 14 are respectively connected to the two sides of the sealing connecting plate 12, and the first plate 11 and the second plate 14 are respectively connected to the two sides of the sealing connecting plate 12 by welding or the like, and when set, the second plate 14 and the sealing connecting plate 12 are extended and protruded relative to the first plate 11 at the edge, that is, the second plate 14 and the sealing connecting plate 12 are larger than the first plate 11, and the extended protruding widening length is set to L, and the length L satisfies: 0.5mm≤L≤2mm, such as Fig. 9 As shown, when the first plate 11 and the sealing connecting plate 12 are welded, the welding overflow can flow to the widened portion of the sealing connecting plate 12 relative to the first plate 11, thereby preventing the welding overflow from flowing to other components and affecting other components. At the same time, the fullness of the welding can be ensured and the welding reliability can be improved. The second plate 14 and the sealing connecting plate 12 are both widened, so that the second plate 14 can provide support for the sealing connecting plate 12, thereby preventing the sealing connecting plate 12 from breaking, etc., and improving the structural strength.

[0050] In some embodiments, the main body 1 further includes a positioning pin 15 , which is positioned and penetrates the first plate 11 , the sealing connection plate 12 , and the second plate 14 in sequence.

The positioning pin 15 is set to at least two, that is, the positioning pin 15 can be set to two, three and four, etc., and at least two positioning pins 15 are spaced apart and distributed on the main body 1. The two positioning pins 15 can form a straight line in the same plane, thereby making the first plate 11, the sealing connecting plate 12 and the second plate 14 more accurate when connected, thereby improving the assembly speed and saving assembly time.

[0054] In some embodiments, the minimum distance between each positioning pin 15 and the boundary of the sealing connecting plate 12 is less than or equal to 30% of the total boundary length of the sealing connecting plate 12, that is, the maximum distance between each positioning pin 15 and the boundary of the sealing connecting plate 12 is equal to 30% of the total boundary length of the sealing connecting plate 12. Setting the minimum distance between each positioning pin 15 and the boundary of the sealing connecting plate 12 to be less than or equal to 30% of the total boundary length of the sealing connecting plate 12 can make the distance between each positioning pin 15 and the boundary of the sealing connecting plate 12 smaller, thereby making each positioning pin 15 arranged at a boundary position close to the sealing connecting plate 12, thereby playing a positioning role between the first plate 11, the sealing connecting plate 12 and the second plate 14 without affecting the setting of the built-in flow channel 111, and achieving a better use effect.
