Claims

[Scope of utility model registration request]

In a vaporizer in which a float chamber 5 is formed by the concave portion 1A of the vaporizer body 1 and the float chamber body 3, and a constant liquid level is formed in the float chamber, a float is placed on the outer side 3A of the float chamber body 3. A cylindrical drain boss 7 with a bottomed drain hole 8 opening at the bottom 5A of the chamber 5 is provided protrudingly, and drain bosses facing each other substantially perpendicular to the longitudinal axis YY of the drain boss 7 are provided. Through holes 9A and 9B are formed in the outer peripheral sides 7A and 7B of the drain boss 7 through the drain hole 8, and the through holes 9A and 9B are provided with an axial length L that is approximately the same length as the outer diameter φA of the drain boss 7. On the other hand, a tubular drain pipe 11 made of an elastic material that closes at least the through holes 9A and 9B is fitted and arranged on the outer peripheral side 7C of the drain boss 7, and at least A pressing protrusion 11C is formed on the outer periphery of the drain pipe 11 corresponding to one of the through holes, so that when the fuel in the float chamber 5 is discharged,
By pressing the pressing protrusion 11C of the drain pipe 11 inward of the drain boss 7, the operating rod 1
0 to the inner circumferential surface 11A of the drain pipe 11.
The other through hole is opened at the outer circumferential side 7C of the drain boss 7 and the inner circumferential surface 1 of the drain pipe 11.
A drain device for a vaporizer formed by forming a gap h connected to the atmosphere between 1A and 1A.
