A booster pump 13 in the water purifier body 1 boosts water in the water tank 101 and pumps the water into a PP cotton filter element 14 in the water purifier body 1 for primary filtration, the primarily filtered water enters an RO reverse osmosis membrane filter 15 of the water purifier body 1 for filtration (under the action of the structure and the function of the RO reverse osmosis membrane filter element 15, the treated concentrated sewage is discharged into a sewage discharge pipe 15-1 through the RO reverse osmosis membrane filter element concentrated sewage discharge pipe 15-1 and enters a sewage discharge pipe 15-2, the sewage discharged from the sewage discharge pipe 15-2 is discharged into a sewage tank of the water purifier body 1 through a pipeline or is directly discharged into an indoor sewage pipeline), the filtered water enters a final stage active carbon filter element 16 of the water purifier body 1, the active carbon filter element 16 treats the filtered water and then enters an electric heating shell 103 from an electric heating shell 103 water inlet pipe of the water purifier body 103 for heating, the heated water flows out from a water outlet pipe 104, and a water valve 17 connected with the water outlet pipe 104; in-process, the water purifier body is under its self internal control system effect, and the user does not open water valve 17, and when water did not flow, control system closed booster pump 13 power, opened booster pump 13 power when water flowed and had the pressurized running water for the input of multistage filter core, guaranteed that water purifier body 1 can normally supply water. In the process of heating water by the electric heating shell 103, under the action of a temperature control switch on the outer side of the shell, after the water temperature in the shell exceeds a certain value, the temperature control switch turns off the power supply of the electric heating pipe of the electric heating shell 103 and stops heating water, and after the water temperature in the shell is lower than a certain value, the temperature control switch turns on the power supply of the electric heating pipe of the electric heating shell 103 again and heats water again, so that the water temperature in the shell 103 is always in a constant temperature state.

In actual cleaning, the plug 105 on the outer side of the water discharge pipe of the water storage tank 101 is removed, so that the turbid water and the cleaning water in the water storage tank 101 after cleaning flow out of the water discharge pipe into a water barrel or directly into a domestic sewer, and after cleaning, the plug 105 is installed again.

In normal use, as shown in fig. 1 and 2, one pole of the 220V ac power supply enters one end of the power input end of the regulated power supply a1 and one end of the main power input end DY of the water purifier body through the relay K to control the power input end and the normally closed contact end, and the other pole of the 220V ac power supply enters the other end of the power input end of the regulated power supply a1 and the other end of the main power input end DY of the water purifier body, so that the regulated power supply a1 and the main power input end DY of the water purifier body are in an.

In the first path of control circuit and the first group of probes T: when water exists in the water storage tank 101 and the water level is not lower than 1cm at ordinary times, the probe T is submerged by water between two copper rods (the distance is 3 mm), then the base electrode of the NPN triode Q is connected with a proper bias voltage (higher than 0.7V) from the 3 feet of the voltage-stabilized power supply A1 through the water and the two copper rods through the adjustable resistor RP, the NPN triode Q is connected with the collector electrode thereof to output a low level to enter the base electrode of the NPN triode Q1, the base electrode of the NPN triode Q1 is in a cut-off state without proper forward bias voltage, the subsequent buzzer B and the light-emitting diode VL cannot be electrified, and the normal use of the water purifier body 1; when the water in the water storage tank 101 is short of water and the water level is lower than 1cm at ordinary times, the probe is not submerged by water between the two copper rods, the resistance is infinite, then the base electrode of the NPN triode Q is not through water, the two copper rods obtain bias voltage from the 3 feet of the stabilized voltage supply A1 through the adjustable resistance RP, the collector electrode of the NPN triode Q is not output any level to enter the base electrode of the NPN triode Q1, the base electrode of the NPN triode Q1 obtains proper bias voltage conduction (higher than 0.7V) from the 3 feet of the stabilized voltage supply A1 through the resistance R for voltage reduction and current limitation, then the NPN triode Q1 conducts the collector electrode thereof to output low level to enter the buzzer B and the cathode power supply input end of the light emitting diode VL, because the buzzer B and the anode power supply input end of the light emitting diode VL (the resistance R1 reduces the voltage of the power supply entering the anode of the light emitting diode VL, and the diode VD1, the low level output by the second control circuit diode VD2 is prevented from entering the light-emitting diode VL to cause the light-emitting diode VL to emit light) and the 3-pin connection of the stabilized voltage power supply A1, so that the buzzer B can be electrified to sound and the light-emitting diode VL can be electrified to emit light at the moment, and a user is simultaneously given an acousto-optic prompt that water needs to be added into the water storage tank 101; after water is added, the NPN triode Q is conducted again because the two copper rods of the probe T are submerged by the water again, and then the buzzer B and the light emitting diode VL are not operated after power failure.
