[0007] In terms of operation, the device requires precise time control and operation coordination, involving multiple steps such as starting the rotating motor, controlling the rotating motor, managing the one-way valve, etc., which not only increases the complexity of operation, but also increases the skill requirement of the operator. At the same time, the maintenance and troubleshooting of the device may be more complex, increasing the inconvenience of operation. INVENTION CONTENTS
