As shown in fig. 1, the control system for the pump and the submersible pump of the water purifier comprises a total power supply 1, a pump 2 and a submersible pump 3, wherein the pump 2 and the submersible pump 3 are started in a time-staggered manner through a time-staggered controller 6, and further description is needed here that the time-staggered starting means that the pump 2 and the submersible pump 3 cannot work simultaneously in the same time period, namely, the pump 3 stops working when the pump 2 works, the pump 2 stops working when the pump 3 works, or the pump 2 and the submersible pump 3 stop working when the pump 3 works, so that the switching power supply only needs to bear one of larger loads in the pump 2 or the submersible pump 3, the cost of the switching power supply can be effectively reduced, and meanwhile, the function of protecting the switching power supply is also achieved.
The booster pump 2 is connected with the main power supply 1 through a first relay 4, the first relay 4 is used for controlling the on-off of the booster pump 2 and the main power supply 1 and is connected with the time-staggered control controller 6, the submersible pump 3 is connected with the first relay 4 through a second relay 5, and the second relay 5 is used for controlling the on-off of the submersible pump 3 and the main power supply 1 and is connected with the time-staggered control controller 6. Specifically, the first relay 4 is a component with two-way switching circuit function, and comprises a public pin 40, a normally closed pin 41, a normally open pin 42, a first magnet 43 and a first coil 44, one end of the public pin 40 is connected with the main power supply 1, a first elastic sheet 401 for movably closing the normally closed pin 41 or the normally open pin 42 is arranged at the other end of the public pin 40, the normally closed pin 41 is connected with the second relay 5, and the normally open pin 42 is connected with the booster pump 2. Specifically, the first elastic piece 401 is a metal elastic piece, and may be made of copper or iron or other metal materials that can be adsorbed by the first magnet 43, the first elastic piece 401 is closed with the normally closed pin 41 in a conventional state, when the second relay 5 is communicated with the total power supply 1 under the control of the time-staggered controller 6, that is, the total power supply 1 is communicated with the submersible pump 3 through the common pin 40, the first elastic piece 401, the normally closed pin 41 and the second relay 5, so that the submersible pump 3 is driven, and at this time, the booster pump 2 is in a power-off state due to the communication of the first elastic piece 401 and the normally closed pin 41. In addition, the first coil 44 surrounds the first magnet 43 and is connected with the error controller 6, when the first coil 44 is electrified under the control of the error controller 6 to generate magnetic force to attract the first elastic sheet 401, the first elastic sheet 401 swings downwards with the common pin 40 as the center after being separated from the connection with the normally closed pin 41 under the attraction of the magnetic force until being in fit connection with the normally open pin 42, and when the first elastic sheet 401 is connected with the normally open pin 42, namely, the main power supply 1 is communicated with the booster pump 2 through the common pin 40, the first elastic sheet 401 and the normally open pin 42, namely, the power supply 2 is electrified with the main power supply 1, so that the booster pump 2 is driven, and at the moment, the submersible pump 3 is in a power-off state due to the fact that the first elastic sheet 401 is connected with the normally open pin 42, so that the error opening of the booster pump 2 and the submersible pump 3 is realized, and the damage of the switch power supply caused by the simultaneous operation of the two is ensured.
Similarly, the second relay 5 is a one-way switch, and comprises a connection pin 50, a second normally open pin 51, a second magnet 52 and a second coil 53, one end of the connection pin 50 is connected with the normally closed pin 41, a second elastic sheet 501 for movably closing the second normally open pin 51 is arranged at the other end of the connection pin 50, the second elastic sheet 501 and the first elastic sheet 401 are made of the same metal material, the second normally open pin 51 is connected with the submersible pump 3, and the second coil 53 is wound on the second magnet 52 and connected with the error controller 6.

The working principle of the invention is as follows.
(1) When the booster pump 2 is required to operate, the single-chip microcomputer 60 outputs: instruction S1 is high and instruction S2 is low. The high-level instruction S1 causes the first MOS transistor Q1 to be turned on, and forms a loop (the power module 61-the first coil 44-the first MOS transistor Q1-GND), so that the first coil 44 is connected with the power module 61 to be electrified and generate magnetic force to attract the first elastic sheet 401 downwards, so that the common pin 40 and the normally open pin 42 of the first relay 4 are turned on, and the booster pump 2 is electrified to operate. And meanwhile, the common pin 40 and the normally closed pin 41 of the first relay 4 are disconnected, so that the working power supply of the submersible pump 3 is cut off. The low-level command S2 causes the second MOS transistor Q2 to be turned off, the second coil 53 of the second relay 5 remains powered off, the connection pin 50 and the second normally open pin 51 of the second relay 5 remain disconnected, and the submersible pump 3 remains powered off.
(2) When the submersible pump 3 is required to operate, the singlechip 60 outputs: instruction S1 is low and instruction S2 is high. The low-level command S1 turns off the first MOS transistor Q1, the first coil 44 of the first relay 4 is kept powered off, the common pin 40 and the normally open pin 42 of the first relay 4 are kept disconnected, the common pin 40 and the normally closed pin 41 are kept conducting, and the working power supply of the booster pump 2 is cut off. The high-level command S2 causes the second MOS transistor Q2 to be turned on, and forms a loop (the power module 61-the second coil 53-the second MOS transistor Q2-GND), so that the second coil 53 is connected with the power module 61 to be electrified and generate magnetic force to attract the second elastic sheet 501 downwards, and the connection pin 50 and the second normally open pin 51 of the second relay 5 are turned on, so that the submersible pump 3 is electrified to operate.
In summary, the invention ensures that the booster pump 2 and the submersible pump 3 do not work simultaneously in the same time, prevents the condition that the booster pump 2 and the submersible pump 3 work simultaneously, prevents the overload of the switching power supply of the water purifier, can configure the switching power supply with low current for the water purifier, and reduces the production cost.
