[0002] Temperature and humidity test chamber is an essential test equipment in the fields of aviation, automobile, home appliances, scientific research, etc. It is used to test and determine the parameters and performance of electrical, electronic and other products and materials after high temperature, low temperature, humidity or constant test temperature environment changes.
[0003] During the experiment of the existing device, the air circulation in the test space is insufficient, which may cause uneven distribution of temperature and humidity, and further lead to differences in temperature and humidity at different positions in the test space. According to the Chinese utility model disclosure patent CN216573149U, a breeze temperature and humidity test chamber is disclosed. During the experiment using the temperature and humidity test chamber, the circulating fan rotates to generate airflow. After the airflow passes through the ventilation plate with ventilation holes, a breeze airflow with good directionality is formed and enters the test space evenly. Afterwards, the breeze airflow enters the return channel through the return air port, and returns to the accommodating chamber through the return channel, and is finally blown into the test space again by the circulating fan, thereby realizing airflow circulation and exchange inside the test space, which helps to improve the uniformity of temperature and humidity in the test space.
[0004] During the experiment, the existing device has insufficient air circulation in the test space, which may cause uneven temperature and humidity distribution, and then lead to differences in temperature and humidity at different locations in the test space. For example, the above-mentioned patent solves this problem, but in actual use, when the humidity of the breeze is high, it is difficult to circulate upward due to gravity, thereby affecting the stability of the airflow circulation.

[0029] When ready for use, the box 11 is placed at the designated position, and then the operator places the required test sample on the placement plate 13, and starts the equipment in the box 11, thereby completing the temperature and humidity setting in the box 11, and then the operator turns on the motor 14 to drive the fan 15 to rotate, and the airflow is formed into a breeze and moves downward, and then the operator turns on the driving mechanism 27, and the driving mechanism 27 drives the connecting rod 25 to move back and forth, and drives the piston 26 to move back and forth in the tube body 24.
