Technical Field

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

[0002] The drug stability test chamber [1] is used in the pharmaceutical industry, medicine, biotechnology industry and all related industries including life sciences. The GMP principle requires 25℃ / 60%RH humidity long-term stability test conditions. In the accelerated test, the 40℃ / 75%RH humidity test standard for 6 months is the stability test system in the pharmaceutical industry. It mainly simulates the temperature, humidity and light test in the environmental climate.

[0003] When conducting a stability test on a drug, a test chamber is required. However, when humidifying, some existing test chambers usually directly fix the mist nozzle inside the test chamber, and then supply water to make the mist nozzle spray, thereby humidifying the inside of the test chamber. However, when humidifying in the above manner, it is easy to cause the mist liquid to be unevenly dispersed inside the test chamber, thereby affecting the uniformity of the drug humidification.

[0004] In view of the above problems, a humidifying device for a drug stability test chamber is proposed. Utility Model Content

[0010] Preferably, a fixed pipe is fixedly installed inside the movable frame.

[0011] Preferably, one end of the connecting water supply hose is fixedly connected to a fixed pipe, and a mist nozzle is arranged on the surface of the fixed pipe.

[0012] Preferably, a rotating cylinder is rotatably sleeved on the fixed tube, and a connecting hole is opened on the surface of the rotating cylinder.

[0013] Preferably, a gear is fixedly sleeved on the rotating cylinder, and a rack is fixedly installed inside the medicine test box body, and the rack is meshingly connected with the gear.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The humidifying device of the drug stability test chamber rotates the connecting hole, and the mist liquid sprayed through the mist nozzle enters the interior of the rotating cylinder and is then discharged through the connecting hole.
