Abstract:
The present disclosure provides a backflow prevention device includes an upper chassis, a lower chassis, a seal member, and a resilient member. The upper chassis defines a receiving space passing through a bottom of the upper chassis. The lower chassis defines an air flow channel. A part of the lower chassis is accommodated in the receiving space of the upper chassis, and fixedly connected to an inner wall of the upper chassis. The upper chassis and the lower chassis are mounted to a pot. The seal member is received in the receiving space. The resilient member is resiliently mounted between the seal member and the upper chassis. The resilient power of the resilient member pushes the seal member to resist against and seal the air flow channel.
