Description

Technical Field

[0001] The utility model relates to the technical field of water replenishing devices, in particular to a water replenishing device for a drug stability test box. Background Art

[0002] At present, the research and development and production of drugs require a lot of tests. Drug stability test chambers have been widely used in the pharmaceutical industry as equipment for monitoring drug stability. They mainly simulate temperature, humidity, and light tests in the environment. During the use of drug stability test chambers, long-term humidity tests are often required. During use, the water in the water tank will gradually decrease. It is necessary to monitor the water level in the water tank manually at all times, and the water tank needs to be frequently replenished. If the water cannot be replenished in time, it will inevitably affect the normal operation of the test. Manual monitoring and replenishment are not only labor-intensive, but also labor-intensive.

[0003] A water replenishing device for a drug stability test box is disclosed in the Chinese utility model patent application disclosure CN 219518881 U. When the water in the water replenishing tank is insufficient, the second liquid level sensor of the device will transmit a signal to the alarm, and the alarm will sound an alarm, thereby instructing the staff to replenish water in time. The water entering the test box can be filtered by setting a filtering structure to prevent impurities in the water from entering the test box and affecting the test results, thereby ensuring the accuracy of the test results. However, there is only one sensor in the container of the device. If it is only used to sense the lowest line of the water level, a maximum limit is required to stop replenishing water inside. Otherwise, when the water is full, it cannot be sensed to stop draining water, thereby affecting the use effect. Utility Model Content
