Further preferably, referring to fig. 2 and 3, the first stopper 220 and the second stopper 320 are each provided with a wind guide surface 500, and the wind guide surface 500 is used for reducing resistance of the airflow. Set up wind guide surface 500 on the stopper, gas can flow along wind guide surface 500 when the stopper removes, effectively reduces the windage that receives when the stopper removes, produces too big resistance to the stopper when avoiding gas flow and leads to the unable effectual delivery outlet that blocks of stopper.
