[0002] In industrial production and scientific research experiments, temperature change test chambers are often used to simulate high-temperature environments to test the temperature resistance or aging characteristics of products. However, during the test, some products may generate fumes due to high temperatures. If this is not monitored in time, it may affect the accuracy of the experimental data and even pose a safety hazard.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Example 1:

[0014] refer to Figure 1-5 A flue gas monitoring device for a temperature change test chamber includes a test chamber 1, and a monitoring mechanism 2 is provided on the top of the test chamber 1; The monitoring mechanism 2 includes a container 21, the bottom of which is bolted to the test chamber 1. A cover 22 is provided on the top of the container 21. A flue gas sensor 23 is bolted to the bottom of the cover 22. An alarm 24 is bolted to the top of the cover 22. A duct fan 3 is connected to one side of the container 21. A first connecting pipe 4 is connected to the other end of the duct fan 3. The other end of the first connecting pipe 4 is connected to the test chamber 1. A second connecting pipe 5 is connected to the other end of the container 21. A heat exchange mechanism 6 is provided at the other end of the second connecting pipe 5.

[0015] Specifically, one end of the first connecting pipe 4 extends into the interior of 1. The duct fan 3 can extract the air from the interior of container 21 through the first connecting pipe 4, creating a negative pressure state inside container 21. The smoke sensor 23 can detect the smoke and then transmit the electrical signal to the alarm 24 for sound and light alarm.

[0016] refer to Figure 1 and Figure 5 The heat exchange mechanism 6 includes a water tank 61. A spring tube 62 is fixedly connected inside the water tank 61. One end of the spring tube 62 is connected to a second connecting pipe 5, and the other end of the spring tube 62 is connected to a third connecting pipe 7. The other end of the third connecting pipe 7 is connected to the test chamber 1. A first control valve 63 is connected to the top of the water tank 61, and a second control valve 64 is connected to the back of the water tank 61. Bases 65 are bolted to both sides of the bottom of the water tank 61, and the bottom of the bases 65 is bolted to the test chamber 1. By setting the spring tube 62, the hot air can be extended through the path. One end of the third connecting pipe 7 extends into the interior of the test chamber 1. By setting the first control valve 63 and the second control valve 64, it is easy to connect the water pipes.

[0017] refer to Figure 3 A sealing gasket 25 is placed on the top of the container 21, and a bolt 26 is fitted inside the cover 22. The bottom of the bolt 26 is threaded to the container 21. By setting the sealing gasket 25, the sealing performance between the container 21 and the cover 22 can be effectively improved. By setting the bolt 26, the cover 22 can be effectively fixed and installed.

[0018] refer to Figure 1 and Figure 2 The test chamber 1 is equipped with a heater. The front of the test chamber 1 is hinged to a door 8. A handle 9 is bolted to the front of the door 8. A male buckle 10 is bolted to one side of the door 8. A female buckle 11 that matches the male buckle 10 is bolted to one side of the test chamber 1. By setting up the heater, the interior of the test chamber 1 can be effectively heated. By setting up the male buckle 10 and the female buckle 11, the opening and closing of the door 8 can be effectively limited.

[0019] Brief description of usage: The user places the product inside the test chamber 1 and heats it up using a heater. When monitoring of flue gas is required, the duct fan 3 can be activated to extract the air from inside container 21 and then discharge it into the test chamber 1 through the first connecting pipe 4. This creates negative pressure in container 21, which draws out the air from inside the test chamber 1 through the second connecting pipe 5, spring tube 62, and third connecting pipe 7, forming an air circulation. The user can connect the water pump outlet pipe to the first control valve 63, place the water pump inlet pipe in the water tank, and connect the second control valve 64 to the drain pipe in the water tank, allowing for the circulation of water between the water tank 61 and the water in the water tank. When hot air inside the test chamber 1 passes through the spring tube 62, the water in the water tank 61 cools the hot air, preventing damage to the flue gas sensor 23. When there is flue gas inside the test chamber 1, it enters the container 21 and is detected by the flue gas sensor 23, triggering an audible and visual alarm via the alarm 24. This effectively facilitates flue gas monitoring and alarm.
