It is understood that the heating tube 232 may also be fixed to the bottom of the heating pan 230. Of course, the heating pipes 232 may be disposed at the same time on the circumferential outer portion and the bottom portion of the heating plate 230.

It is understood that the fuse plug 721 may also be an alloy fuse plug 721 with a fusing temperature requirement.

It is understood that the elastic member of the fuse unit 720 may be other elastic members according to the structural requirements.

It is understood that the predetermined fusing temperature T1 of the heating plate 230 can be set to other reasonable temperature values such as 200 ℃, 210 ℃, 220 ℃, 230 ℃, 235 ℃, 245 ℃, 250 ℃, 260 ℃, 270 ℃, 280 ℃ and the like.

It is understood that the preset superheat temperature T2 of the heating plate 230 can be set to other reasonable temperature values such as 120 ℃, 125 ℃, 130 ℃, 135 ℃, 145 ℃, 150 ℃, 155 ℃, 160 ℃ and the like.

It is understood that the support frame 260 and the bottom end of the cup 210 may be fixedly connected by other suitable structures such as a screw-fit structure.

It will be appreciated that the provision of an upper shroud may be eliminated, provided that the upper coupler 510 meets the structural requirements.

It will be appreciated that the provision of the lower skirt 140 may be eliminated, provided that the lower coupler 520 meets the structural requirements.

It is understood that other heating members may be employed in place of the heating tube 232.

In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope defined by the appended claims.
