Circuit for automatically controlling water pumping and water pumping device employing same

Abstract

The invention provides a circuit for automatically controlling water pumping. The circuit comprises a water pump, a first input end, a first output end, a second input end, a second output end, a high water level switch, a low water level switch and a relay, wherein the relay has a first normally-opened contact and a second normally-opened contact, the first input end is connected with the first output end through the high water level switch, the low water level switch and the relay, the first input end and the first output end are connected with a first power supply, the first normally-opened contact is parallelly connected with the low water level switch, the second input end is connected with the second output end through the water pump and the second normally-opened contact, the second input end and the second output end are connected with a second power supply. The invention further provides a water pumping device employing the circuit. The water pumping device realizes unattended automatic water pumping and prevents water shortages and overflowing.

Description

technical field [0001] The invention relates to the field of automatic control of pumping, in particular to a circuit for automatic control of pumping and a pumping device with the circuit. Background technique [0002] With the rapid development of science and technology, people's living standards have also been improved one after another. When using water, they no longer use pressurized wells to carry water back and forth, which is time-consuming and labor-intensive. Most residents now use pumps to pump water to water towers, pools or water tanks to form their own "tap water" system. However, these pumping systems are manually controlled, and it is difficult to grasp the amount of water in the water tank. If you don't pay attention, it will overflow or run out of water , which brings a lot of inconvenience to the lives of residents, especially water overflow, which wastes water resources and wastes electricity resources at the same time.

[0002] With the rapid development of science and technology, people's living standards have also improved one after another. When using water, it is no longer a pressurized well, and it is time-consuming and labor-intensive to carry water back and forth.

Most residents now use pumps to pump water to water towers, pools or water tanks to form their own "tap water" system. However, these pumping systems are manually controlled, and it is difficult to grasp the amount of water in the water tank. If you don't pay attention, it will overflow or run out of water , which brings a lot of inconvenience to residents' lives, especially water overflow, which wastes water resources and wastes electricity resources at the same time.
