[0032] The present invention has the following beneficial effects:

[0033] 1. The present invention detects the ozone destruction efficiency by using a device. The efficiency is calculated by the ratio of the ozone concentration difference before and after the experiment to the time. The ozone destruction efficiency can be detected relatively simply and directly, and the detection time is greatly reduced, the detection difficulty is reduced, and the detection efficiency is improved.

[0034] 2. In the present invention, gas enters the interior of the filter tank, and the movement of the first movable ball causes the filter screen to rotate to block the filter tank through the connecting shaft, thereby filtering the gas, improving the cleanliness of the gas, preventing dust from affecting the detection results, improving the accuracy of the detection, and preventing dust from damaging the detector.

[0035] 3. When other gases except ozone are input into the experiment through the input pipe of the present invention, the second movable ball is knocked out by the air pressure, so that the gas enters the interior of the filter tank. At this time, the first movable ball is affected by the air pressure of the filter tank and moves to the smaller opening of the first conical tube to block the first conical tube. When gas is input into the air intake pipe, the second movable ball will also block the second conical tube in the same way to prevent backflow into the interior of the vacuum pump, thereby protecting the pipeline and the vacuum pump.

[0036] 4. After the detection is completed, the first three-way valve of the present invention opens the exhaust pipe, and then other gases except ozone in the experiment are input from the input pipe, and the second three-way valve is connected to the filter tank, which enters the detector to bring out the ozone therein and discharges it from the exhaust pipe, thereby preventing the residual gas in the detector from affecting the destruction efficiency detection and improving the accuracy of the detection.

[0037] 5. In the present invention, after ozone is discharged from the exhaust pipe, a lot of gas will inevitably be wasted when the gas is input into the input pipe. At this time, the connection direction of the second three-way valve is changed to connect it with the gas storage pipe, and the gas enters the air bag and is stored. When the ozone in the detector is cleared next time, the gas stored in the air bag can be used first, and then the gas is input through the input pipe, which improves the utilization efficiency of the gas and prevents the waste of gas.

[0038] 6. When the gas is input through the input pipe, the first movable ball is subjected to the air pressure of the filter tank and moves toward the smaller opening of the first conical tube. At this time, the connecting shaft drives the filter to rotate, so that the filter is in a position that is easy to clean, thereby reducing the difficulty of cleaning.

[0039] 7. The present invention drives the filter to rotate through the connecting shaft, so that when the filter is placed horizontally, the gas input from the input pipe will also clean the dust on the filter and discharge it through the exhaust pipe, making the filter cleaner and improving the cleaning effect.

[0040] 8. The present invention increases the airflow input from the input pipe to drive the rotating wheel in the installation pipe to rotate, and the other rotating wheels of the rotating wheel system are responsible for transmission to rotate the rotating disk, and a crank slider system is formed through the connecting rod slide rail and the slide rod to convert the rotational motion into a linear reciprocating motion, driving the movable rod to move back and forth, so that the cleaning brush moves. At this time, the filter screen is also parallel to the cleaning brush, and the bristles of the cleaning brush are aligned with the filter screen to brush off the more stubborn dust on it, thereby improving the cleaning effect of the filter screen.

[0041] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In the detection of ozone concentration, the air pump 310 draws the air in the experiment into the air inlet pipe 220, and the gas first passes through the first conical tube 1501, and the first movable ball 1502 is knocked out by the air pressure and moves to the larger opening of the first conical tube 1501, so that the gas enters the filter tank 1201. The movement of the first movable ball 1502 causes the filter screen 1203 to rotate to block the filter tank 1201 through the connecting shaft 1204, thereby filtering the gas, and then entering the detector 210.

[0083] After the test is completed, the first three-way valve 1303 opens the exhaust pipe 230, and then other gases except ozone in the experiment are input from the input pipe 240.

[0084] After ozone is discharged from the exhaust pipe 230, a lot of gas will inevitably be wasted when the gas is input into the input pipe 240. At this time, the connection direction of the second three-way valve 1304 is changed to connect with the gas storage pipe 1301, and the gas enters the air bag 1302 and is stored. When the ozone of the detector 210 is cleared next time, the gas stored in the air bag 1302 can be used first, and then the gas can be input through the input pipe 240.
