The fixing plate 33 is fixedly connected to the outside of the evaporator 1, and the end of the locking plate 31 is clamped with the fixing plate 33. The fixing plate 33 can not only limit the clamping of the locking plate 31, but also support and limit the preheating arc shell 2, to prevent the preheating arc shell 2 from vertically sliding and separating from the outside of the evaporator 1.

[0022] Specifically, a locking groove matching the locking rod 32 is opened on the side of the outer wall of the preheating arc shell 2, and a connecting block 34 is symmetrically fixedly connected to the end of the locking plate 31.
