Description
Technical Field
[0001] This utility model belongs to the field of experimental equipment technology, and in particular relates to a constant temperature and humidity test chamber. Background Technology
[0002] Temperature and humidity test chambers are used to test the performance of materials under various environmental conditions and to test the heat resistance, cold resistance, dryness resistance, and moisture resistance of various materials. Temperature and humidity test chambers require the intermittent addition of water to maintain the humidity level inside the chamber. Existing temperature and humidity test chambers use water pipes to inject water to maintain humidity, but the water level cannot be guaranteed to reach the required level during the injection process, which can affect the test results.

The temperature control component is connected to the heating component and controls the heating component. The water level control component is connected to both the heating component and the temperature control component. The water level control component includes a water tank with an insulation layer inside, which is disposed on the inner wall of the water tank. The water tank is connected to an inlet component, a water level control component, and a drain component. The inlet component and the drain component are connected to the water tank, and the water level control component is connected to the inlet component. Liquid enters the water tank from the inlet component, and the water level in the water tank is controlled by the water level control component. Liquid in the water tank flows out from the drain component. The heating component heats the liquid in the water tank, and the temperature control component controls the temperature of the liquid in the water tank.
[0005] The heating component includes a heating strip and a power cord. One end of the heating strip is connected to the side of the water tank and heats the liquid in the water tank.
