1. An anti-siphonage water storage device, set in a cleaning water path of a sanitary cleaning device, comprising:
a water tank for storing cleaning water, and
a heating cavity disposed in the water tank, wherein:
the water tank comprises a water inlet structure,
the water tank comprises an overflow structure comprising an overflow pipe,
the water inlet structure comprises a water inlet pipe,
the water inlet pipe comprises a water outlet located in the water tank,
the overflow pipe is disposed away from the water outlet of the water inlet pipe,
a water outlet surface of the water outlet defines a water outlet surface of the water inlet structure,
the heating cavity is configured to in fluid communication with a water pump,
the water pump provides transportation power to transport the cleaning water,
the heating cavity heats the cleaning water provided from the water tank,
the water outlet surface of the water inlet pipe is higher than an overflow surface of the overflow pipe to enable excess cleaning water of the cleaning water to flow out of the overflow surface of the overflow pipe, and
the overflow surface of the overflow pipe is higher than a bottom end of the heating cavity, so that an external heat dissipation of the heating cavity is configured to preheat the cleaning water in the water tank.
