There are two glove holes 7 arranged on the test chamber 1, and operating gloves are arranged on each glove hole 7; the operator can open or close the transfer door through the operating gloves and can transfer items between the transfer window 2 and the test chamber 1.

[0031] A mixing fan 13 electrically connected to the controller 3 is further arranged in the test chamber 1. After the mixing fan 13 is turned on, it can promote the full mixing of the gas in the test chamber 1.

[0032] The airtight and protective disinfection test chamber 100 of this embodiment further includes a differential pressure sensor 15 for detecting the pressure difference between the air inlet and the air outlet of the circulation fan 16.

[0033] The dehumidification module 10 is a container filled with a moisture-absorbing material. The moisture-absorbing material is molecular sieve, silica gel or activated carbon, and the moisture-absorbing material can be selected according to actual needs; the catalytic module 11 is a container filled with a catalyst. The catalyst is used to decompose the disinfection factor in the disinfectant.

[0035] The specific working principle of the airtight and protective disinfection test chamber 100 of this embodiment is as follows:

[0036] (1) When it is necessary to heat the air in the test chamber 1: Open the electric valve 12 between the heating module 9 and the circulation fan 16, and control the heating module 9 to start heating the air through the controller 3. The circulation fan 16 makes the air in the test chamber 1 circulate through the heating module 9, so as to adjust the air temperature in the test chamber 1.

[0037] (2) When it is necessary to humidify the air in the experimental chamber 1: The flash evaporator 23 starts to heat up. The metering pump 25 is opened through the controller 3 to inject pure water in the water storage bottle 5 into the flash chamber for evaporation, thereby humidifying the air. The circulation fan 16 makes the air in the experimental chamber 1 circulate through the flash evaporator 23 to adjust the air humidity in the experimental chamber 1.

[0038] (3) When it is necessary to dehumidify the air in the experimental chamber 1: The circulation fan 16 makes the air in the experimental chamber 1 circulate through the dehumidification module 10 to adjust the air humidity in the experimental chamber 1.

[0039] (4) When it is necessary to inject a disinfection factor into the experimental chamber 1: Two methods can be adopted. One is to directly inject it into the experimental chamber 1 from an external disinfection factor generator through the gas interface in the multi-functional quick-change interface module or the gas injection port on the experimental chamber 1; the other is that the flash evaporator 23 heats up, and the disinfection liquid in the disinfection solution storage bottle 6 is injected into the flash chamber through the corresponding metering pump 25 for evaporation and vaporization, and then enters the experimental chamber 1. The circulation fan 16 makes the air in the chamber circulate through the heating module 9 and the flash evaporator 23. During the above two processes of injecting the disinfection factor, the mixing fan 13 in the chamber blows the air to promote the rapid and uniform diffusion of the disinfection factor entering the experimental chamber 1; the concentration of the disinfection factor in the experimental chamber 1 is monitored by the disinfection factor concentration detection device 20, and when the concentration reaches the standard, the flash module stops working.

[0040] (5) After the disinfection operation is completed, it is necessary to remove the residue of the disinfection factor in the experimental chamber 1: Two methods can be adopted. One is to make the air in the experimental chamber 1 circulate through the circulation fan 16, the catalytic module 11 and the flash evaporator 23. When the air passes through the catalytic module 11, the disinfection factor in the air will be decomposed under the action of the catalyst in the catalytic module 11, thereby completing the residue removal work; the other is that all 3 electric valves 12 are closed, and clean external air is supplemented from the air supplement port 18, enters the experimental chamber 1 through the flash evaporator 23, and the air in the experimental chamber 1 is directly discharged to the external environment or exhaust equipment such as a fume hood through the exhaust port 17 through the circulation fan 16, thereby completing the rapid residue removal.
