At ordinary times, the electromagnetic water valve DC1 is in a power-off state, the inner valve core is opened, so that external tap water enters the first single-stage filter element 1 through the inner valve core of the electromagnetic water valve DC1, water filtered and purified by the single-stage filter element 1 flows out of the one-way water valve 8 (the one-way water valve 9 prevents the water from flowing reversely into the second single-stage filter element 2), and in practical application, after a user opens the water valve 17, the filtered and purified water can be drunk. When the interior of the first single-stage filter element 1 is not damaged and the filtered and purified water is qualified, impurities in the water flowing out of a water outlet pipe of the first single-stage filter element are low, the conductivity is low, at the moment, a base electrode of an NPN triode Q1 is subjected to voltage reduction and current limitation through two copper rods T1, water and an adjustable resistor RP1, the voltage obtained from a pin 3 of a switching power supply A1 is lower than 0.7V, a collector of the NPN triode Q1 is in a cut-off state and has no output, a PNP triode Q2 is not conducted, a relay J1 cannot be electrified and attracted, and an electromagnetic water valve DC1 is in a power-off state, so that a user can normally drink the. In practical use, when the interior of the first single-stage filter element 1 is damaged and water after filtration and purification is unqualified, impurities in the water flowing out of a water outlet pipe of the first single-stage filter element are high, the conductivity is high, at the moment, a base electrode of an NPN triode Q1 is subjected to voltage reduction and current limitation through two copper rods T1, water and an adjustable resistor RP1, the voltage obtained from a pin 3 of a switching power supply A1 is higher than 0.7V, the NPN triode Q1 is in a conducting state, a collector electrode of the NPN triode Q1 outputs low level to enter a base electrode of a PNP triode Q2, the PNP triode Q2 is conducted, a collector electrode of the PNP triode Q2 outputs high level to enter an anode power supply input end of a relay J1 (a cathode power supply input end of the relay J1; because the control power supply input end of the relay J1 is connected with the 3 feet of the switch power supply A1, the normally open contact end of the relay J1 is connected with the electromagnetic water valve DC1 and the anode of the light-emitting diode VL1 (the electromagnetic water valve DC1 and the cathode of the light-emitting diode VL1 are connected with the 4 feet of the switch power supply A1), one end of the resistor R1 is connected with the anode power supply input end of the relay J2 and the control power supply input end, the electromagnetic water valve DC1 can be used as an electric tool to close the inner valve core thereof (the light-emitting diode VL1 is powered on to emit light to prompt a user that the inside of the first single-stage filter element 1 is damaged and needs to be replaced or cleaned, and the resistor R3 is a light-emitting diode VL1 for reducing the voltage and limiting current), so that tap water does not enter the first single-stage filter element; the 12V power supply charges an electrolytic capacitor C1 through a resistor R1; within 5 seconds of the initial charging, when the electrolytic capacitor C1 is not fully charged, the base voltage of a power supply entering an NPN triode Q5 after voltage reduction and current limitation through resistors R1 and R2 is lower than 0.7V, the NPN triode Q5 is cut off, the collector of the NPN triode Q5 is not output, and the input end of a control power supply of the relay J2 is communicated with a normally closed contact end when the relay J2 is in a power-off state; because the normally closed contact end of the relay J2 is connected with the positive electrode of the electromagnetic water valve DC3 (the negative electrode of the electromagnetic water valve DC3 is connected with the 4 feet of the switching power supply A1), the electromagnetic water valve DC3 can be used as an electric tool to open the inner valve core thereof within 5 seconds, thus, the unqualified water remained in the single-stage filter element 1 after the first single-stage filter element 1 is damaged and the electromagnetic water valve DC1 is closed can flow out into the water receiving tank 16 through the bypass water pipe 15 and the one-way water valve DC3 with the opened valve core, and the problem that the unqualified water remained in the single-stage filter element 1 and the water outlet pipeline thereof is drunk when a user drinks purified water filtered by the subsequent. After the electrolytic capacitor C1 is charged for 5 seconds and fully charged, the base voltage of the power supply entering the NPN triode Q5 is higher than 0.7V after the voltage is reduced and the current is limited by the resistors R1 and R2, the NPN triode Q5 conducts the collector of the NPN triode Q5 to output low level and enters the negative power supply input end of the relay J2 (the positive power supply input end of the relay J2 is communicated with the pin 3 of the switch power supply A1 through the normally open contact end of the relay J1), therefore, the relay J2 is in an electric-on pull-in state, the control power supply input end and the normally closed contact end are open, and the control power supply input end and the normally; because the normally closed contact end of the relay J2 is connected with the positive electrode of the electromagnetic water valve DC3, after 5 seconds, the electromagnetic water valve DC3 loses power and does not work any more, and the inner valve core is closed, so that water cannot flow out of the bypass water pipe 16 when the subsequent second single-stage filter element 2 filters and purifies water; because the control power supply input end of the relay J3 of the second control circuit is connected with the normally open contact end of the relay J2 (the negative power supply input end of the relay J3 is connected with the 4 pins of the switching power supply A1), the control power supply input end of the relay J3 of the second control circuit can be electrified after the internal valve core of the electromagnetic water valve DC3 is closed for 5 seconds.
As shown in fig. 1 and 2, after the relay J3 of the second control circuit controls the power input end to be powered on, because the normally closed contact end and the negative power input end of the relay J3 of the second control circuit are respectively connected with the power input ends of the second electromagnetic water valve DC2, at this moment, the electromagnetic water valve DC2 can be used as an open internal valve core of the electromagnetic water valve DC2, so that external tap water enters the second single-stage filter element 2 through the internal valve core of the electromagnetic water valve DC2, and water filtered and purified by the single-stage filter element 2 flows out from the one-way water valve 9 (the one-way water valve 8 prevents the water from flowing backwards into the first single-stage filter element 1). When the interior of the second single-stage filter element 2 is not damaged and the filtered and purified water is qualified, the water flowing out of the water outlet pipe has low impurities and low conductivity, at the moment, the base electrode of the NPN triode Q3 is subjected to voltage reduction and current limitation through the two copper rods T2, the water and the adjustable resistor RP2, the voltage obtained from the pin 3 of the switching power supply A1 is lower than 0.7V, the NPN triode Q3 is in a cut-off state, the collector electrode of the NPN triode Q3 has no output, the PNP triode Q4 is not conducted, the relay J3 cannot be electrified for attraction, the electromagnetic water valve DC2 is continuously in an electrified state, and a user normally drinks the filtered and purified water of. In practical use, when the interior of the second single-stage filter element 2 is damaged and the filtered and purified water is unqualified, impurities in the water flowing out of a water outlet pipe of the second single-stage filter element are high, the conductivity is high, at the moment, the base electrode of an NPN triode Q3 is subjected to voltage reduction and current limitation through two copper rods T2, water and an adjustable resistor RP2, the voltage obtained from a pin 3 of a switching power supply A1 is higher than 0.7V, the NPN triode Q3 is in a conducting state, the collector electrode of the NPN triode Q3 outputs low level to enter the base electrode of a PNP triode Q4, the PNP triode Q4 is conducted, the collector electrode of the PNP triode Q4 outputs high level to enter the anode power supply input end of a relay J3 (the cathode power supply input end of the relay J3 is connected with a pin 4 of the switching; because the relay J3 controls the power input end to communicate with the 12V power positive pole through the relay J2, J1, the relay J3 normally closed contact end is connected with the electromagnetic water valve DC2 positive pole, so the electromagnetic water valve DC2 will lose electricity and no longer work its internal valve core to close at this moment, has prevented users from drinking the water after not having been effectively filtered and purified; because the anode of the light emitting diode VL2 is connected with the normally open contact end of the relay J3 through the resistor R4 (voltage reduction and current limitation), and the cathode of the light emitting diode VL2 is communicated with the 4 pins of the switching power supply A1, the light emitting diode VL2 can be powered to emit light at the moment, and a user is prompted that the second single-stage filter element 2 is damaged and needs to be replaced or cleaned. Through the above, in the novel practical application, the first single-stage filter element 1 filters and purifies water at ordinary times, so that purified drinking water is provided for a user; when the first single-stage filter element 1 damages the filtering and purifying water, the filtering and purifying water performance is poor, the conductivity of impurities in water exceeds the standard and is increased, the first control circuit can control the first electromagnetic water valve DC1 to be closed and the second electromagnetic water valve DC2 to be opened, so that tap water can automatically continuously provide filtered and purified water for a user through the second single-stage filter element 2, and simultaneously, before the first single-stage filter element and the second single-stage filter element are switched to filter and purify water, the third electromagnetic water valve DC3 can be opened to discharge water which is not effectively filtered and purified and is arranged between the water outlet valve 17 and the water outlet pipeline 14, and the situation that the water which is remained in the water outlet pipeline and is not effectively filtered and purified is drunk by. This is novel in the use, take place the filtering purification effect variation when one of them filter core 1, aquatic impurity exceeds standard, another filter core 2 can continue to provide the water after purifying for the user automatically (can temporarily not change and wash first set of filter core in a period), guaranteed to change and wash before first filter core 1, the user can also normally drink the water after the filtering purification, and take place the filtering purification performance variation at two filter cores, the aquatic impurity can give the user suggestion respectively the very first time when exceeding standard, the user just can in time wash and change the filter core that the filtering purification performance variation. This is novel can bring the convenience for the user to guaranteed that user's drinking water is healthy, and improved product market competition, (second filter core 2 damages the back and in time need change or wash, before second filter core 2 does not damage, does not change first filter core 1 for the user and continues the water and provide the assurance). The novel water dispenser can bring convenience to users, ensures the drinking water health of the users and improves the market competitiveness of products. The novel water receiving tank 16 can be pulled out and poured after being filled with water and then put into the shell.
As shown in fig. 2, during production, a manufacturer needs to determine the resistance values of the adjustable resistors RP1 and RP2, specifically, two one-way water valves 8 and 9 are directly connected to two water outlet pipes at the lower end of a clean water tank, then other qualified water purifiers are placed in the water tank for treatment, and water quality detection equipment detects qualified water, and then part of tap water (the proportion of tap water to qualified water is about 1:1.5, which is equivalent to that the effect of subsequent filter element treatment water is poor, and the treated water is slightly better than the tap water and lower than the water quality of normal filtered water) is added into the water tank; then, the user firstly adjusts the resistance value of the adjustable resistor RP1, and when the light emitting diode VL1 is just adjusted to emit light, the resistance value of the adjustable resistor RP1 is adjusted to be required (about 3.76M); then the user adjusts the resistance value of the adjustable resistor RP2, and when the light emitting diode VL2 is just adjusted to emit light, the resistance value of the adjustable resistor RP2 is adjusted to be required (about 3.76M); finally, the user disconnects the adjustable resistors RP1 and RP2 from the circuit respectively, measures the resistance value by using a resistance meter, the measured resistance value is the resistance values of the adjustable resistors RP1 and RP2 required by production, the subsequent production does not need to be adjusted, the resistors of the adjustable resistors RP1 and RP2 are adjusted in place before direct production, or fixed resistors with the same resistance value are used for replacing the resistors.
As shown in FIG. 2, the resistors RP1, RP2 are sized at 4.7M (adjusted to about 3.76M); the resistances of the resistors R1, R2, R3 and R4 are 1M, 470K, 1.8K and 1.8K respectively; the model of the electrolytic capacitor C1 is 4.7 uF/25V; relays J1, J2, J3 are DC4123 type 12V miniaturised relays; the models of NPN triodes Q1, Q5 and Q3 are 9014, 9013 and 9014 respectively; the model numbers of NPN triodes Q2 and Q4 are 9012; the light emitting diodes VL1, VL2 are red light emitting diodes.
