Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, a rotatable gas path blocking ball 3 is arranged in a gas path connecting hole 2 arranged on a gas path plate 1, and the gas path blocking ball 3 realizes blocking and opening of a gas path through rotation of a vertical worm 4 inserted into the gas path plate 1;
