摘要： A drain for sanitary fixtures such as sinks, tubs or the like is described. The drain is provided with an automatic overflow mechanism, of the magnetic type, configured to be automatically activated when the water level in the sanitary fixture reaches the maximum level allowed. The overflow mechanism comprises a first magnetic element arranged on a stem of the plug, and a second magnetic element integral with the head of the plug and in-between the base and the first magnetic element. In the raised position of the plug, corresponding to the raised position of the head, the first magnetic element and the second magnetic element are magnetically coupled. When a threshold value of the water pressure acting on the head is exceeded, the first magnetic element and the second magnetic element are automatically uncoupled, causing the descent of the head towards the lowered position, corresponding to the opening of the mouth of the sanitary fixture initially closed by the plug. The drain preferably further comprises a manual lifting mechanism to lift the plug, configured to bring back the plug to the raised closed position following activation. Preferably, also the lifting mechanism is magnetic.

摘要： A drain for sanitary fixtures such as sinks, tubs or the like is described. The drain is provided with a lifting mechanism to lift the plug and configured to bring back the plug to the raised closed position following an activation. The lifting mechanism is magnetic and comprises a magnetic element mounted aboard the plug and a stationary magnetic element in the body of the drain. A spring functionally interposed between the base of the drain and the plug and which exerts an upwards thrust on the latter, i.e. towards the raised position, is also present. In the raised position of the plug, the magnetic elements are magnetically coupled, i.e. attract one another. The drain further comprises an automatic overflow mechanism configured to be automatically activated when the water level in the sanitary fixture reaches the maximum level allowed. The overflow mechanism is magnetic too.
