Screwed into the screw holes 9a, 9a provided in the attachment portions 9, 9 of the outer piece 2.

  As a result, in the present heat evaporator 1, the outer piece 2, the inner piece 3 and the heating element 4 formed in one piece can be assembled with the two screws S, and the number of parts and the number of screws can be reduced and manufactured at low cost. .

  Further, in a state where the inner piece 3 is accommodated in the outer piece 2 and assembled, the inner surface of the outer piece 2 (tongue 6) has a smaller gradient than the gradient of the outer surfaces of the straight portions 19a, 19a. The portions 19a and 19a are strongly pressed against the tongue-shaped portion 6, the rigidity of the straight portions 19a and 19a is increased, and the outward deformation of the straight portions 19a and 19a is suppressed.

  Further, as described above, the gap G is formed between the tongue 6 and the arc 19b, the arc 19b can be elastically deformed, and the liquid container V can be easily attached and detached.

  Moreover, the usage method of the heating vaporizer of this embodiment is demonstrated.

  The user removes the lid of the liquid container V containing the chemical solution and attaches it to the heating evaporator 1 as shown in FIGS. 6 and 8.

  Since the liquid container V is made of a synthetic resin and is blow-molded, a holding projection vb is often provided only on one surface (front surface) of the liquid container V in order to simplify the mold.

  Therefore, the liquid container V is inserted between the bottom opening 2b of the inner piece 3, that is, the concave portion 17 on the inner surface of the inner piece 3 and the container holding portion 19 with the surface provided with the holding protrusion vb as the front.

At this time, since the inter-tongue 6 and the arc portion 19b gap G is formed, by resilient deformation of the arc portion 19b, the holding projections vb of the liquid container V, the container holding portion 19 of the substantially U-shaped The anti-holding projection side of the liquid container V abuts against the peripheral wall of the inner surface of the inner piece 3 where the concave portion 17 is raised, and the holding projection vb is held by the arc portion 19b.

  In this way, the liquid container V is attached to the heating evaporator 1 so that the holding protrusion vb is in front, and the user mistakenly makes the anti-holding protrusion side of the liquid container V the front, and the holding protrusion side is the back face. Thus, even if the liquid container V is inserted into the inner piece 3, the holding projection vb is accommodated in the concave portion 17 on the inner surface of the inner piece 3, and the projection 18 supports the lower portion of the holding projection vb. And the solution will not spill.

  In a state where the liquid container V is attached to the heating evaporator 1, the liquid absorption core P passes through the liquid core insertion hole 12a and the liquid core insertion hole 21a surrounded by the heating element 4, reaches the upper part of the outer piece 2, and absorbs the liquid. The tip of the liquid core P faces the transpiration port 2a.

  When the attachment of the liquid container V to the heating evaporator 1 is completed, the plug 5 is inserted into an outlet and the heating element 4 is energized.

  The liquid absorbent wick P is heated by the heating element 4, and the chemical liquid sucked up by the liquid absorbent wick P evaporates and is evaporated from the evaporation port 2a to the outside.

  In the process of transpiration of the chemical solution, as shown in FIGS. 6 and 7, since the air supply port 20 is formed between the opening 19 c and the inner surface of the outer piece 2, air can be reliably supplied into the outer piece 2. .

  According to the heating evaporator of the present embodiment, an inexpensive heating evaporator can be realized by reducing the number of parts and the number of screws.
