Claims

[Scope of utility model registration request]

(1) Installation of a passage pipe in a vaporizer for press-fitting and welding a metal passage pipe into a press-fit hole drilled in the main body so as to communicate with the passage in the main body of the synthetic resin vaporizer is carried out in accordance with the structure of the passage pipe. At the tip of the tube, starting from the front side along the press-fitting direction, there is a conical part whose diameter becomes smaller toward the front side and whose maximum outside diameter is equal to or slightly smaller than the inside diameter of the press-fit hole, and a conical part whose outside diameter is equal to or slightly smaller than the inside diameter of the press-fit hole, and A passage pipe in a vaporizer, characterized in that an annular groove having an outer diameter smaller than the outer diameter of the diameter portion and a large diameter cylindrical portion having an outer diameter slightly larger than the inner diameter of the press-fit hole are formed. The installation is structural.

(2) Utility model registration claim No. (1) characterized in that ultrasonic press-fitting and welding are used as the press-fitting and welding.
The installation of the passage pipe in the vaporizer described in Section 1.
