[0002] With the improvement of people's living standards, the quality of domestic water has deteriorated, and pure water has become more and more popular. Household water purification equipment is gradually entering the family. Water outlet pressure, control the start and stop of the pressurized water pump, and timing recoil. The water purifier has certain requirements for the tap water pressure used by the user. It will cause the water purifier to enter the water cut-off protection state, and the water purifier cannot continue to work normally, resulting in the user being unable to use the water purifier and other products normally.
Existing water purification equipment cannot visually display various fault states, which brings great inconvenience to maintenance

The invention discloses a water purifying device control circuit which comprises a transformer B, a rectifier diode Z1, a rectifier diode Z2, a light-emitting diode D1, a light-emitting diode D2, a light-emitting diode D3, a low-voltage switch K1 and a high-voltage switch K2. The two ends of a primary coil of the transformer B are connected with the two ends of a 220 V alternating current respectively, and the two ends of a secondary coil of the transformer B are connected with the positive electrode of the rectifier diode Z1 and the positive electrode of the rectifier diode Z2 respectively. The rectifier diode Z1 is connected with the negative electrode of the rectifier diode Z2, the light-emitting diode D1, the negative electrode of the light-emitting diode D2, and the low-voltage switch K1. The positive electrode of the light-emitting diode D2 is connected with the low-voltage switch K1, a water pump M and a water inlet electromagnetic valve J. The other end of the water inlet electromagnetic valve J is connected with the other end of the water pump M, the negative electrode of the light-emitting diode D3 and the high-voltage switch K2. By means of the water purifying device control circuit, various failure states can be visually displayed through the light-emitting diode D1, the light-emitting diode D2 and the light-emitting diode D3, and maintenance and overhaul are convenient.
Description
technical field [0001] The invention relates to a control circuit, in particular to a water purification equipment control circuit. Background technique [0002] With the improvement of people's living standards, the quality of domestic water has deteriorated, and pure water has become more and more popular. Household water purification equipment is gradually entering the family. Water outlet pressure, control the start and stop of the pressurized water pump, and timing recoil. The water purifier has certain requirements for the tap water pressure used by the user. It will cause the water purifier to enter the water cut-off protection state, and the water purifier cannot continue to work normally, thus causing the user to be unable to use the water purifier and other products normally. Existing water purification equipment cannot intuitively display various fault states, which brings great inconvenience to maintenance. Contents of the invention [0003] The purpose of th...
