It can be seen from Fig. 2 that the water inlet and water outlet of the utility model are all arranged at the bottom, and the structure of the whole machine is compact and simple. The tap water enters through the solenoid valve 1 and directly reaches the pressure detector 2. If the water pressure is higher than the setting, the host and the pressure detector 2 are opened, and the tap water reaches the air-water mixer 3, and the air dried by the air dryer 4 enters the ozone generation Ozone generator 5, ozone generator 5 generates ozone under high voltage state, the gas containing ozone enters gas-water separator 6 from pipe 2, and is transported to gas-water mixer 3 through gas-water separator 6 and one-way valve 7 , mixed with water that meets the pressure requirements to make ozone water that meets the concentration requirements. The ozone water flows through the outer wall of the ozone generating tube to cool the ozone generating tube, and then flows to the input end of the reversing valve 8. Adsorber 9 is connected with drinking water outlet. The ozone adsorber 9 absorbs ozone and other particles in the ozone water, so that the drinking water reaching the drinking water outlet is sterile and free of impurities. The gas and water separator 6 can separate the unexpected backflow water from the gas and discharge it from the gas and water separator 6 to prevent the accidental backflow water from entering the ozone generating tube.

As can be seen from Fig. 3, the ozone generator 5 is tubular, and only a single air chamber is arranged in terms of structure, and there is a water channel between the single air chamber and the shell, and the water with ozone flows through the outer wall of the ozone generating tube, which prevents The water is accumulated, and the purpose of cooling the ozone generating tube is achieved. It can be seen from Fig. 1 and Fig. 2 that the ozone generator 5 utilizes the air dried by the air dryer 4 to produce ozone through high-voltage discharge, and a one-way valve made of special materials is set between the ozone generator 5 and the gas and water mixer. Valve 7, the one-way valve 7 is composed of an upper valve body, a valve core, a lower valve body and a spring: the gas containing ozone is sucked in from the air inlet, and due to the action of air pressure, the spring is compressed and deformed, and the valve core moves down , At this time, there is a gap between the upper valve body and the valve core, and the gas enters and passes through the one-way valve 7. If the air inlet has no air pressure, then because of the reset action of the spring, the spool seals the air inlet, which can prevent the water in the gas and water mixer 3 from flowing back into the ozone generator 5.

As can be seen from Fig. 4, a pressure detector 2 with a simple structure is arranged at the water inlet of the utility model. The connected ejector rod also moves upward; when the pressure transmission film moves up to the supporting ring, the pressure spring moves downward to control the movement of the pressure transmission film and ejector rod; if the water pressure is large enough, the ejector rod can move up to Move the switch, the utility model works normally. When the water pressure of the tap water is lower than the design requirement, due to the pressure reset effect of the spring, the ejector rod and the pressure transmission film move downward, the micro switch recovers, the host sends out a low water pressure alarm and automatically shuts down, and has the function of low water pressure automatic protection Function.

As can be seen from Figure 5, the gas and water separator 6 arranged between the one-way valve 7 and the ozone generator 5 is composed of a base, a one-way valve, a PVC hose, two gas and water separation joints, and the gas outlet flows backwards. After the incoming water-containing gas reaches the gas-water separation joint at the upper end, due to the high specific gravity of water, the water flows through the PVC hose to the upper valve body of the built-in one-way valve, and the gas enters through the air-water separation joint at the lower end. The air inlet of the ozone generator; when the water weight in the PVC hose is greater than the rebound force of the spring, the valve core moves down and the water in the hose is discharged. Therefore the function of gas, water separator 6 is: (1) gas and water are separated;

It can be seen from Figure 7 and Figure 8 that under normal operation, open the reversing valve 8, that is, K1 or K2 is connected, that is, IC7 is turned on, and T11 is turned on. IC5 is triggered and turned on to power on the high-voltage generating circuit IC1, which generates a pulse waveform signal to drive T1 and T2 to conduct, so that B2 generates high voltage, so that the ozone generating tube generates ozone. T9 detects the water pressure signal at the water outlet of the water inlet solenoid valve F1. If the water pressure is sufficient, it outputs a low voltage to the third pin of IC3, so that the first pin of IC3 outputs a low level. Part of the circuit is working, and the ozone generator 5 is working normally; if the water pressure is insufficient, it will output high level to pin 3 of IC3, so that pin 1 of IC3 will output high level, power off IC5 and IC7, and turn off the high voltage The power supply of some circuits and the water inlet solenoid valve F1 protect the ozone generator 5 and achieve the purpose of no water protection. During use, it can also automatically perform over-voltage protection. The 14th pin of IC3 detects and compares the feedback voltage of the high-voltage package. When the feedback voltage is higher than the set value, the 16th pin of IC3 outputs a high level, causing IC2 to trigger And it is in a latched state; at this time, the pin 9 of IC2 outputs a high level to cut off the power supply of IC1, thereby shutting off the power supply of the high-voltage circuit and the power supply of the water inlet solenoid valve F1. When it is necessary to clear the latch state, the power of the whole machine must be cut off for about 30 seconds.

In this embodiment 1, the pressure detector 2 works sensitively. When the water pressure is lower than 0.1MPa, the main engine will automatically shut down and give an alarm through the control circuit. The accidents of the machine; the single valve 7 has good ozone resistance and strong backstop function, which can effectively prevent the backflow of water; the washing water outlet and the drinking water outlet are all set at the lowest point, which avoids the phenomenon of water in the machine after shutdown.
