Patent attributes
A waterproof electronic device including a body, a one-way valve, and a cover is provided. The body has a first hole, which penetrates the body and communicates with an external environment, and a chamber. The one-way valve disposed on an inner surface of the body communicates with the first hole. The one-way valve has a main runner, multiple shunt runners, and multiple stopper blocks. Each stopper block is located between the main runner and a corresponding shunt runner. The cover disposed on the one-way valve has a second hole communicated with the one-way valve and the chamber. When a fluid enters the one-way valve from the second hole, the fluid is discharged from the body through the first hole. When the fluid enters the one-way valve from the first hole, the fluid generates a resistance in the one-way valve.
