Patent attributes
The present utility model relates to a vacuum breaker, an automatic flushing system for toilet having the vacuum breaker, and an electric bidet toilet having the automatic flushing system for toilet. The vacuum breaker comprises a body and a cover which cooperate to define a cavity, the body being integrally formed with an inlet pipe section which defines a water inlet and an outlet pipe section which defines a water outlet, the cover being formed with an air port, wherein a tip portion of the inlet pipe section extends into the cavity in a direction towards the air port. The length of the tip portion of the inlet pipe section which extends within the cavity is greater than half of the height of the cavity. According to the present utility model, because the tip portion of the inlet pipe section extends almost throughout the cavity of the vacuum breaker, the level of the water inlet is elevated, so that the CL (critical level) line is raised.
