<p>A control circuit for an automatic flush urinal comprises a main control circuit (3), and an electromagnetic valve (1) and a detection circuit (2) electrically connected to the main control circuit (3), the detection circuit (2) is formed of a Hall sensor (5) installed on the urinal body and a permanent magnet (6) installed at the corresponding position of the door body. The detection circuit (2) has a low cost and can lower the cost of the product. The detection manner in which the Hall sensor (5) and the permanent magnet (6) are adopted is simple to control and reliable, and incorrect operations do not occur.</p> |
