Abstract

A negative pressure water dispenser. The negative water dispenser includes a case (1), a water outlet (2), a operation platform (3), a bucket cover (4), a bucket (5), a water pump (6), a heating plate (7), an inner tank (8), a nozzle connecting piece (9), electromagnetic valves (10, 13), a joint (11), water temperature sensors (12, 15), a water vapor condensation chamber (17), silica gel tubes (14, 16, 18, 22, 25), a power panel (19), a power panel cover (20), a float switch (21), a impoundment disc cover (23) and a impoundment disc (24). The bucket of the negative pressure water dispenser is made of a thin plastic material. When the water volume in the bucket is reduced, the volume of the bucket will be continuously reduced, and maintained consistent with the water volume. The air pressure in the bucket is less than outside atmospheric pressure, thereby forming a negative pressure which can assure a smooth water output and avoid bubble generation due to entering of external air into the bucket. The hot water volume and the temperature of the negative pressure water dispenser can be set itself. A child lock key is arranged on the negative pressure water dispenser. Long pressing the child lock key to unlock is needed before heating, so that children's misoperation can be prevented, the scald is effectively avoided, and safety is higher.
