The outer diameter of the hook frame 18 is smaller than the inner diameter of the housing 23 and is larger than the diameter of the hook ring 34 at the bottom of the housing. Pedestal 22 is a circular plate structure, which is placed on the support plate 32 of the temperature sensor unit 24. The outer diameter of the pedestal 22 is formed smaller than the diameter of the locking ring 34. When the descending spraying body 17 descends, the support plate 22 and the connecting table 19 pass through the lower end of the housing 23 and the engaging ring 34, and only the engaging frame 18 is the engaging ring 34 of the housing 23. Caught).

The downward spraying body 17 is further provided with a rubber stopper 15 installed at the bottom of the pedestal 22 and in close contact with the tip of the outlet pipe 12 to block the outlet pipe. Protruding portion 25 for mounting the rubber stopper 15 is formed at the center of the pedestal 22.
