Claims

[Scope of Claim for Utility Model Registration] In a vaporizer in which a float chamber 5 is formed by the recess 1A of the vaporizer body 1 and the float chamber body 3, and a constant liquid level is formed in the float chamber, the float chamber body The bottom part 5 of the float chamber 5 is attached to the outer part 3A of 3.
A cylindrical drain boss 7 provided with a bottomed drain hole 8 opening at A is provided protrudingly, and the outer peripheral sides of the drain bosses 7 are substantially orthogonal to the longitudinal axis YY of the drain boss 7 and face each other. The operating rod 10 has through holes 9A, 9B penetrating through the portions 7A, 7B through the drain hole 8, and has an axial length L that is approximately the same length as the outer diameter φA of the drain boss 7 in the through holes 9A, 9B. are movably arranged, and on the other hand, at least through holes 9A and 9B are provided in the outer peripheral side 7C of the drain boss 7.
A tubular drain pipe 11 made of an elastic material that closes the through hole is fitted and disposed, and a pressing protrusion 11C is formed on the outer periphery of the drain pipe 11 corresponding to at least one of the through holes, and further includes a pressing protrusion. On the outer periphery 11B of the drain pipe 11, the outer periphery 11B of the drain pipe 11 is located at a position substantially opposite to each other.
Relief portions 12A and 12B that do not press the
Pressing part 12C that presses the outer periphery of the drain pipe 11
. By pressing the pressing protrusion 11C toward the inside of the drain boss 7,
By moving the operating rod 10, the other through hole is opened on the inner circumferential surface 11A of the drain pipe 11, and a gap h is created between the outer circumferential side 7C of the drain boss 7 and the inner circumferential surface 11A of the drain pipe 11, which communicates with the atmosphere. A drain device for a vaporizer formed by forming a
