A circuit breaker 15 is provided on the far side of the fan motor 16 and near the top corner of the housing 1.

[0015] As one implementation method in this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 As shown, an observation window 2 is provided on the door corresponding to the left chamber of the enclosure 1, and a water tank 8 is provided on the top of the enclosure. A door handle 3 is provided on the side of the observation window 2. A control panel 4 is provided on the side of the door handle 3 and near the side of the enclosure 1. A water level observation port 7 is provided above the control panel 4, and a button area 5 for the control circuit is provided below the control panel. An electrical box door 6 is provided near the water level observation port 7 and on the side of the enclosure. A product rack 14 is provided behind the observation window 2. A test hole 10 is provided near the middle of the side of the product rack 14 and near the side of the enclosure 1. A circuit breaker 19 is provided on the side corresponding to the right chamber of the enclosure and near the top corner of the enclosure 1.

[0016] In the event of a power outage, open the electrical box door 6 to check the circuit. If there are no problems, close the electrical box door 6 and pull the door handle 3 near the observation window 2 to open the door of the left chamber of the enclosure 1. Check if the product rack 14 is damaged or unstable. If there are no problems, place the sample on the product rack 14. If the sample has other parameters to be tested, a power cord or signal line can be led out through the test hole 10 to connect the sample. Pull the door handle 3 to close the door of the left chamber of the enclosure 1. Observe the water level through the water level observation port 7. If there are no problems, turn on the power by switching the circuit breaker 19. Set the required parameters through the button area 5 and the control panel 4 to make the equipment run.

[0017] As one implementation method in this embodiment, please refer to Figure 2 , Figure 3 , Figure 4As shown, an air outlet 9 is located below the water tank and in the left compartment of the housing 1. A humidification trough 13 connected to the inner wall of the housing is located in front of the air outlet 9. A water guide trough 12 is located below the humidification trough 13. An air return vent 11 is located behind the water guide trough 12 and below the air outlet 9. A fan motor 16 is located on the outer surface of the housing 1 and near the air outlet 9. A water cup 18 is located in the middle of the right compartment of the housing 1. A humidification tank 21 is located near the water cup 18. A condenser 20 is located below the humidification tank 21. A compressor 19 is located near the condenser 20. A distribution panel 17 is located above the compressor 19.

[0018] After the equipment is started, the circuit of the distribution panel 17 is powered on. The compressor 19 draws in gas and compresses it into high-temperature and high-pressure gas. After the gas enters the condenser 20, it releases heat to the outside through air cooling or water cooling and condenses into high-pressure liquid refrigerant, which lowers the temperature of the left chamber of the cabinet 1. At the same time, it creates a favorable working environment for the humidification tank 21. The humidification tank 21 and the humidification tank 13 work together. The water cup 18 precisely controls the water level and delivers water to the humidification tank 21 and the humidification tank 13. The humidification tank 13 works with the humidification tank 21 to make steam humidification adjustments to ensure the humidity of the left chamber of the cabinet 1. The fan motor 16 works independently, driving the airflow through the air outlet 9 and the air return vent 11 to complete the air circulation. At the same time, it is more conducive to the change of temperature and humidity in the left chamber of the cabinet 1. The condensate produced after the equipment has been running for a long time is discharged through the water guide trough 12.

[0019] Working principle: This constant temperature and humidity test chamber involves the coordinated operation of multiple components. The compressor 19 and condenser 20 change the temperature of the chamber 1 by releasing heat to the outside. At the same time, the fan motor 16 operates, working with the air outlet 9 and the air return vent 11 to accelerate the internal air circulation. The two work together to facilitate temperature change and also create a favorable working environment for the humidification tank 21 and the humidification chamber 12. The water cup 18 controls the water flow and delivers it to the humidification tank 21 and the humidification chamber 12. Under the control of the control system, the two work together to change the humidity of the chamber 1.

[0020] It is worth mentioning that by reducing the number of water cups 18 from multiple to one, the space occupied is reduced, and the arrangement of other components is also facilitated. By placing the water tank 8 on top, the internal space of the box 1 where the product rack 14 is located is improved, allowing more samples to be placed, while also reducing costs and facilitating maintenance and inspection. The compact and simple arrangement further optimizes the overall volume of the test chamber, which can be used directly on a table or on a mobile shelf, greatly increasing flexibility and reducing the footprint.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
