The utility model discloses a water tank
siphon breaking device, particularly relates to
water treatment technical field, including first water tank, second water tank, water pump and fan, the lower side of outer surface of first water tank is fixedly equipped with first connecting
pipe, and the first connecting
pipe is fixedly connected with the inlet of water pump, the outlet of water pump is fixedly equipped with second connecting
pipe. According to the water tank
siphon breaking device, in actual work, under the condition that a water pump is started, the
check valve is automatically closed, waste water in the first water tank enters the second water tank through the first connecting pipe, the second connecting pipe and the
water pipe, when the water pump is stopped, the
check valve is opened, the draught fan operates, and the water tank is broken. And external air and air in the first water tank enter the second
siphon breaking pipe and enter the
water pipe through the conveying pipe and the first siphon breaking pipe, the siphon state is destroyed, and therefore the siphon state can be destroyed, and the situation that water in the first water tank enters the second water tank under the uncontrolled condition is avoided.
