[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This ozone generator's outlet anti-backflow and water return device is equipped with an outlet water return pipe. Ozone gas is output from the ozone gas outlet port of the ozone generator cylinder. The ozone gas flow rate is adjusted by the opening of an electric switch valve, and the flow of ozone gas is turned on and off by a manual switch valve. The ozone gas enters the U-shaped pipe along the first ozone gas pipe, and then enters the second ozone gas pipe through the U-shaped pipe. The pipe is connected to an external pipe through an external flange, allowing the ozone gas to be delivered to the ozone usage point. This forms the ozone gas flow from the ozone generator cylinder to the user's ozone gas usage point. The outlet water return pipe flow is orderly, clear, easy to install, and very practical. It plays an essential role in maintaining the long-term normal and stable operation of ozone equipment.
[0014] 2. This ozone generator's outlet anti-backflow and water return device is equipped with a pipe drainage device and a pipe backflow detection device. Backflow water and water vapor from the user's ozone usage point enter the U-shaped pipe along the ozone pipe, and all backflow water is concentrated at the lowest point of the U-shaped pipe. The pipe drainage device is located at the lowest point of the U-shaped pipe. Backflow water reaches the drain pipe at the bottom of the U-shaped pipe. A stainless steel cylindrical body is welded to the drain pipe, located at the lowest point of the U-shaped pipe. A PTFE insulated column is screwed into the stainless steel cylindrical body, and then the positive and negative electrode columns are screwed into the PTFE insulated column. The tail ends of the positive and negative electrode columns extend beyond the positive electrode column. The liquid level electrode is positioned at 2 cm, and a transparent glass cover is installed outside it for dust and water protection. The copper core signal wires at the front ends of the positive and negative electrode posts are led out from the outlet hole of the transparent glass cover to the program control panel in the ozone generator's electrical control cabinet to collect signals. The pipeline drainage device consists of a drain pipe, a manual drain valve, and an electric drain valve. The manual drain valve can drain water as needed, while the electric drain valve can be set by the program control panel in the ozone generator's electrical cabinet to drain water once during each start-up, once during each shutdown, and once when water is detected by the pipeline backflow detection device. When the electrical signals of the positive and negative electrodes are connected, and the U-tube V signal is fed back to the program control panel of the ozone generator's cylinder electrical control cabinet, the electric drain valve opens immediately to drain water. Even a small amount of visible water exceeding the positive electrode of the pipe backflow detection device will create a positive-negative circuit between the positive and negative electrodes via the U-tube V. The resulting electrical signal is transmitted to the program control panel, forming a backflow signal that can promptly stop the equipment operation. Simultaneously, the electric switch valve is immediately stopped and closed, and the electric drain valve is opened to drain water, forming an automatic linkage operation between the ozone generator's cylinder electrical control cabinet program control panel and the system. This system prevents backflow from entering the high-voltage discharge tube inside the ozone generator cylinder, thus avoiding damage to the high-voltage discharge tube and preventing ozone equipment malfunctions. It establishes a backflow signal detection and drainage process from the user's ozone usage point to the ozone pipeline backflow detection and drainage device, which then feeds back the signal to the program controller and electric / manual drain valve for timely drainage. The pipeline drainage device and backflow detection device enable the program control console to automatically collect signals and automatically operate the electric valves. The operation and control are simple, practical, and effective, saving time, labor, and costs, with low operating expenses, high efficiency, energy saving, and environmental friendliness.

[0028] Working principle: During use, ozone gas is output from the ozone gas outlet port 11 of the ozone generator cylinder 1. The ozone gas flow rate is adjusted by the electric switch valve 22, and the flow of ozone gas is turned on and off by the manual switch valve 23. The ozone gas enters the U-shaped pipe 24 through the ozone gas pipeline 1 21, and then enters the ozone gas pipeline 25 through the U-shaped pipe 24. The external pipeline is connected to the external pipeline through the external flange 26, so that the ozone gas is delivered to the ozone usage point. This forms the ozone gas flow from the ozone generator cylinder 1 to the user's ozone gas usage point. The gas outlet and water return pipeline 2 is arranged in an orderly manner, which is easy to see and install. It is very practical and plays an essential role in maintaining the long-term normal and stable operation of the ozone equipment.The return water and water vapor from the ozone usage point enter the U-shaped pipe 24 along the ozone pipe 25, and the return water is concentrated at the lowest point of the U-shaped pipe 24. The pipe drainage device 3 is located at the lowest point of the U-shaped pipe 24. The return water reaches the drain pipe 31 at the bottom of the U-shaped pipe 24. The stainless steel cylindrical body 41 is welded to the drain pipe 31 and is located at the lowest point of the U-shaped pipe 24. The PTFE insulating column 42 is screwed into the stainless steel cylindrical body 41. Then, the positive electrode column 43 and the negative electrode column 44 are screwed into the PTFE insulating column 42. The tail ends of the positive electrode column 43 and the negative electrode column 44 extend one to two centimeters beyond the positive electrode column 43 as the liquid level electrode positions. A transparent glass cover 45 is installed on the surface to seal against dust and water. The copper core signal lines of the positive electrode post 43 and negative electrode post 44 are led out from the outlet hole 46 of the transparent glass cover 45 to the program control console 5 in the electrical control cabinet of the ozone generator cylinder 1 to collect signals. The pipeline drainage device 3 consists of a drain pipe 31, a manual drain valve 32, and an electric drain valve 33. The manual drain valve 32 can drain water as needed. The electric drain valve 33 can be set by the program control console 5 of the electrical cabinet of the ozone generator cylinder 1 to drain water once during each start-up, once during each shutdown, and when water is detected by the pipeline backflow detection device 4. The positive electrode post 4... When the electrical signals of the positive electrode 44 and the negative electrode 3 are connected, and the U-shaped tube 24V connection signal is fed back to the program control panel 5 of the ozone generator cylinder 1 electrical control cabinet, the electric drain valve 33 opens to drain water immediately. As long as a small amount of visible water level exceeds the positive electrode 43 of the pipeline backflow detection device 4, a positive and negative circuit of the U-shaped tube 24V between the positive electrode 43 and the negative electrode 44 can be formed. The resulting electrical signal is transmitted to the program control panel 5, forming a backflow signal that can stop the equipment operation in time. At the same time, the electric switch valve 22 is immediately stopped and closed, and the electric drain valve 33 is opened to drain water, thus forming the program of the ozone generator cylinder 1 electrical control cabinet. The automatic linkage operation of console 5 prevents backflow from entering the high-voltage discharge tube inside the ozone generator cylinder 1, thus avoiding damage to the high-voltage discharge tube and preventing ozone equipment malfunctions. It establishes a backflow signal detection and feedback process from the user's ozone usage point to the ozone pipeline backflow detection and drainage device, which then relays the signal to the program controller and electric / manual drain valve for timely drainage. Through the pipeline drainage device 3 and the pipeline backflow detection device 4, the program control console 5 automatically collects signals and automatically operates the electric valve. The operation and control are simple, practical, and effective, saving time, labor, and costs, with low operating expenses, high efficiency, energy saving, and environmental friendliness.
