摘要

device inserted in a solenoid valve to allow service pressures of up to 500 kpa in an electric shower equipped with a presence sensor. device introduced in a solenoid valve to allow service pressures of up to 500kpa in an electric shower equipped with a presence sensor, the present patent application aims to end the villain of water and electricity consumption, only of consumption of water can account for about 45% of total residential consumption, a 15-minute bath, for example, can use up to 140 liters of water. one of the ways to combat this waste is the use of a shower with presence sensor, which consists of the assembly of a conventional electric shower inserted in a hydraulic system equipped with a solenoid valve to control the passage of water. this valve is activated by an infrared sensor that identifies the presence of the user, or his absence, under the shower, avoiding unnecessary expenditure of water consumption during the bath, when its flow is dispensable, such as lathering, applying shampoo / conditioner, and other occasions.
