[0035] Specifically, a mounting shell 15 is fixed to the bottom of the exhaust pipe 3, and the mounting shell 15 is fixedly connected to the top of the oven 1. The mounting shell 15 is installed above the exhaust port of the oven 1, and a flange 13 is fixedly connected to the top of the exhaust pipe 3.
