Abstract
A backflow prevention device including a tank inside of and moveable relative to a housing. A cap coupled to the housing and including inlet and outlet chambers fluidly connected through an inlet, the outlet chamber communicating with the tank. A shell is connected to the cap and includes a shell inlet chamber, which communicates with a first outlet hole of the inlet chamber, and a second outlet hole, which communicates with the tank. An inlet sealing member opens/closes the inlet to fluidly connect/disconnect the inlet chamber and the outlet chamber; and an outlet hole sealing member is moveable with the tank to open/close the second outlet hole. Closing the second outlet hole prevents water from flowing through the second outlet hole and switches the inlet from open to closed. Opening the second outlet hole allows water to flow through the second outlet hole and switches the inlet to open.
