Embodiment Construction

[0023] see figure 1 and figure 2 The home safety water-saving device provided by the first embodiment of the present invention includes a processor 101, a water flow sensor 102, a timer 103, a transformer 113, and a motor 104; the water flow sensor 102 is fixed on the water pipe 203, and the sensing part of the water flow sensor 102 is connected to the water pipe 203 is in contact with water, and the water flow sensor 102 is connected to the processor 101 . The timer 103 is connected to the processor 101 .

[0024] The motor 104 is connected to the power supply through the transformer 113, and is connected to the processor 101 through the motor driving circuit. This device does not require excessive voltage, so a transformer 113 is needed to provide a lower voltage to ensure its stable operation.

[0025] The home safety water-saving device also includes a casing 105, which accommodates the processor 101, the timer 103, the motor 104 and the transformer 113 inside. The ca...

Abstract

The invention provides a domestic safe water saving device, and belongs to the field of water flow control devices. The domestic safe water saving device comprises a processor, a water flow sensor, a timer and a motor. The water flow sensor is arranged on a water pipe, the sensing portion of the water flow sensor extends into the water pipe, and the water flow sensor is connected with the processor; the timer is connected with the processor; the output end of the motor is fixedly connected with a valve of the water pipe. According to the domestic safe water saving device, when the water flow sensor detects water flow, the timer starts timeing; when the water flow sensor detects no water flow, the timer stops timing and resets; when time of the timer exceeds a certain value, the processor controls the motor to rotate through a motor drive circuit, the valve is closed, and water does not flow out any more, so that waste of water resources is avoided, and the situation that houses are submerged or floors are rotten due to water and other situations are avoided.

Description

technical field [0001] The invention relates to the field of water flow control devices, in particular to a family safety water-saving device. Background technique [0002] In the existing water facilities, in some unexpected situations, the faucet will accidentally flow out of water. These situations include but are not limited to: accidental cracking of water pipes or faucets; . [0003] If this happens and no one goes to turn off the tap for a long time, it will lead to wasted water resources, flooded houses, soaked floors and other situations. Contents of the invention [0004] The present invention provides a family safety water-saving device, aiming to solve the above problems. [0005] The present invention is achieved like this: [0006] A family safety water-saving device, including a processor, a water flow sensor, a timer and a motor; [0007] The water flow sensor is arranged on the water pipe, and its sensing part extends to the inside of the water pipe, a...
