[0006] The above technical scheme is adopted, support leg is blocked and fixed to bottom ring at the same time, so that fluorinated salt discharging is not blocked by support leg.

[0007] Preferably, the side surface of the installation frame is fixedly installed with blocking rubber ring, and the outer surface of the blocking rubber ring is attached to the outer surface of the feeding port.

[0008] The above technical scheme can effectively reduce the noise generated when installation frame is contacted with feeding port when vibrating.
