Background technique

Water resources are an important natural resource indispensable to the development of the national economy. In many parts of the world, the demand for water has exceeded the capacity of water resources, and many regions are also on the verge of water imbalance. my country is the country with the largest water consumption in the world, and its per capita water resources are about 1/4 of the world's per capita. After ranking in the top 100, China is listed as one of the few countries in the world with poor per capita water resources. Therefore, it is particularly important to save water and promote low-carbon life in our country.

In real life, we adjust the water output of the faucet by twisting or pulling the switch of the faucet.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-3, an automatic control water-saving device for an intelligent environmental protection faucet of the utility model includes a first infrared sensor 2, a second infrared sensor 3, a first electromagnetic valve 4, a second electromagnetic valve 5, A controller 6 , a first three-way joint 9 , a second three-way joint 10 , a first shunt pipe 11 , a second shunt pipe 12 and a water volume regulating valve 13 .

The first infrared sensor 2 is installed on the upper side wall of the faucet body 1 . The second infrared sensor 3 is installed on the outer wall facing the water outlet in the middle of the faucet body 1 . And the controller 6 is installed on the inner lower side of the faucet main body 1 . The controller 6 is a minimum single-chip system, and the first infrared sensor 2 and the second infrared sensor 3 are respectively connected to the input interfaces of the controller 6 . As shown in FIG. 2 , the first branch pipe 11 , the second branch pipe 12 and the water inlet pipe 7 are connected through the first three-way joint 9 . Then, the first branch pipe 11 , the second branch pipe 12 and the water outlet pipe 8 are connected through the second three-way joint 10 . The first electromagnetic valve 4 is installed on the first branch pipe 11 and controls the opening and closing of the water channel in the first branch pipe 11 . The second solenoid valve 5 is installed on the second branch pipe 12 and controls the opening and closing of the water channel in the second branch pipe 12 . Moreover, the first electromagnetic valve 4 and the second electromagnetic valve 5 are respectively connected to the output interface of the controller 6 . A water volume regulating valve 13 is also installed on the first branch pipe 11, and this water volume regulating valve 13 is used to manually control the water flow in the pipe. The size of the water flowing through the first distribution pipe 11 needs to be set in advance according to the general water consumption of the water user in the specific installation place of the device. It is generally recommended to be set to about half of the water flow in the water inlet pipe 7, so that the needs of general water users can be met, thereby achieving the purpose of saving water.

Both the first solenoid valve 4 and the second solenoid valve 5 are normally closed solenoid valves. That is, when the first infrared sensor 2 and the second infrared sensor 3 do not sense human hands, both the first electromagnetic valve 4 and the second electromagnetic valve 5 are closed, and no water flows out of the faucet.

The operation of turning on the faucet and the water output is small: People usually do not need a large amount of water when using water, so they only need to put their hands normally under the water outlet of the faucet. Now the second infrared sensor 3 has sensed the human hand, and then sends a signal to the controller 6, and then the controller 6 sends a control signal to the first solenoid valve 4 to make the first solenoid valve 4 open. At this time, less water will flow out of the faucet, and this less water flow is set in advance by operating the water volume regulating valve 13 according to the needs of most water users. This avoids that the water will flow out at the maximum flow every time the tap is turned on, even if people do not need such a large amount of water. And then reached the purpose of saving water resources.

The operation of turning on the faucet with a large amount of water: when people need a large flow of water, such as to fill the container, they must first pass the first infrared sensor 2, which is the upper right side of the faucet body 1, and wait for 2-6 seconds. (It can be adjusted appropriately according to the needs) and put it under the water outlet of the faucet. During this process, the first infrared sensor 2 first senses that someone's hand has passed, and sends a signal to the controller 6, and within a few seconds, the second infrared sensor 3 also senses the hand, and sends a signal to the controller 6. At this time, the controller 6 sends a control signal to the second solenoid valve 5 to open the second solenoid valve 5 . Since there is no water regulating valve installed on the second branch pipe 12, the water flow rate flowing through the second branch pipe 12 is the same as the water flow rate flowing through the water inlet pipe 7, that is, the maximum water output of the faucet. The reason why there is an interval of a few seconds between passing the first infrared sensor 2 and placing it under the faucet outlet is to prevent someone from accidentally passing the first infrared sensor 2 without triggering the second infrared sensor 2. Infrared sensor 3 has just left, and makes the next water user who does not need large flow of water trigger the second infrared sensor 3 to flow out the water of large flow, causing the waste of water resources.

The operation of closing the faucet: no matter after using a small flow of water or after using a large flow of water, as long as the hand is withdrawn from the sensing range of the second infrared sensor 3, the first electromagnetic valve 4 or the second electromagnetic valve 5 will be activated immediately. From the on state to the off state. Therefore, when people want to use water with a small flow rate after using up the water with a large flow rate, they only need to withdraw their hands from the sensing range of the second infrared sensor 3, and then turn on the water tap with a small flow rate after the water tap is closed. In the same way, it is also possible to use a large flow of water after the small flow of water is used up. Repeatedly like this, the size of the water flow can be adjusted at any time as required.
