  • Patent number: 10502350
    Abstract: A quick water intake device comprises a tubular main body. The main body has a channel, and a first seal core, and an elastic piece. Under the action of the elastic piece, the first seal core can block the channel. A second seal core is also slidably arranged inside the main body. The second seal core is located between the first seal core and an outlet end of the main body, and when subjected to forces, the second seal core can move toward the first seal core and drives the first seal core to compress the elastic piece. A sealing structure arranged between an outer wall of the second seal core and an inner wall of the main body can form a seal between an outer wall of the second seal core and the main body to block the channel when the second seal core moves toward the outlet end.
