Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in figures 1 and 2, the automatic sterilizing device for the experimental animal cage is suitable for sterilizing the animal cage for raising the small animals (such as white rabbits and mice) of animal experiments before raising, and specifically comprises a cuboid-shaped closed sterilizing space 1, wherein the sterilizing space comprises a rectangular top wall 11 and side walls 12 connected with four edges of the top wall, and the top wall and the side walls form splicing through a splicing structure, so that the sterilizing space is convenient to rapidly disassemble and assemble.

After the animal cage is completely disinfected in the disinfection space, the disinfection space can be disassembled into a top wall, a side wall and the like, so that the animal cage is convenient to store and transport, and the occupied space is reduced. When the animal cage needs to be disinfected again, the top wall and the side walls can be quickly spliced into a closed disinfection space.

Of course, it is necessary to provide corresponding sealing strips between the top wall and the side walls, and between the side walls and the bottom surface, to ensure that the inside of the sterilization space is closed. Furthermore, the sterilization space may also comprise a bottom wall lying flat on the ground, in order to facilitate sealing between the side wall and the bottom wall.

In order to facilitate the disinfection of the animal cage, the disinfection space comprises an inlet 13 arranged on the front side wall and an outlet 14 arranged on the rear side wall, the inlet and the outlet are respectively provided with an air sealing door 2, and the periphery of the air sealing door is provided with an inflatable sealing ring.

When the inflatable sealing ring is not inflated and is in a 'shriveled' state, the air sealing door can be conveniently opened, closed and tightened; when the air sealing door is closed and the air is filled in the air sealing ring, the air sealing door, the inlet and the outlet can be uniformly and reliably sealed, and the inside of the disinfection space is ensured to be in a closed state.

Of course, a transparent observation window 21 can be arranged on the airtight door so as to conveniently observe the disinfection state of the animal cage in the disinfection space.

In addition, a disinfection device and a gas filtering device are also arranged in the disinfection space, as shown in fig. 3, the gas filtering device comprises an air inlet pipe 3, an air outlet pipe 4 and an air supply device for conveying air from the air inlet pipe to the air outlet pipe, a liquid tank type air inlet filter 31 is arranged on the air inlet pipe, and an exhaust air filter 41 is arranged on the air outlet pipe. The air supply device can enable air to enter from the opening end of the air inlet pipe and output from the outlet end of the air outlet pipe, and in the process, the liquid tank type air inlet filter and the air exhaust filter can filter and purify the air in the air inlet pipe and the air outlet pipe.

It will be appreciated that the open end of the inlet duct may be located on the top or side wall of the sterilization space and facing outwardly, and the open end of the outlet duct may be located within the sterilization space. Thus, the air inlet pipe can suck external air, and then the air is filtered by the air filtering device and then is output to the disinfection space; alternatively, the open end of the air inlet pipe can be arranged in the disinfection space. Therefore, the air inlet pipe can also directly suck the air in the disinfection space, and the air is filtered by the air filtering device and then is output outwards. So that the air in the disinfection space is always kept in a 'purification' state before disinfection, and the subsequent disinfection of the animal cage is facilitated.

In addition, the air supply device comprises a power blower 5 arranged on the air inlet pipe and a power exhaust fan 6 arranged on the air outlet pipe.

In addition, a man-machine operation control system can be arranged on the outer side of the disinfection space, so that the arrangement and the operation of a disinfection device, a gas filtering device, an air supply device and the like in the disinfection space are facilitated for workers.

Preferably, the sterilization device comprises a chemical sterilization generation module 7, a decomposition device 71 that can decompose the sterilization gas generated by the chemical sterilization generation module. The chemical disinfection generating module can generate disinfection gas such as hydrogen peroxide and the like so as to comprehensively and effectively disinfect the animal cage and the inside of the whole disinfection space. The decomposition device can decompose the disinfection gas generated by the chemical disinfection generation module, thereby avoiding the disinfection gas from generating adverse effects on the environment and the workers entering the disinfection space.

Since the chemical sterilization generating module and the corresponding sterilizing gas decomposing device belong to the prior art, they will not be described in detail in this embodiment.

As an alternative or complement, the disinfection apparatus comprises a number of high-energy uv lamps 8 arranged at the top of the disinfection space, the uv rays emitted by the uv lamps being able to disinfect the animal cage, the inner surface of the disinfection space and even the air effectively, and it is simple in construction and easy to operate, in particular without the air inside the disinfection space having a negative effect on the staff entering the disinfection space. That is, the chemical disinfection generation module and the ultraviolet lamp can be used simultaneously or separately to meet the disinfection requirements under different conditions.

Further, the man-machine operation control system comprises an entrance operation screen 9 arranged beside the air sealing door at the inlet of the disinfection space and an exit operation box 91 arranged beside the air sealing door at the outlet of the disinfection space. Wherein set up the operation panel of advancing in disinfection space import one side both make things convenient for the staff to the setting and the control of disinfection device, gas filtration device, air supply arrangement etc. inside the disinfection space, the convenient control to the airtight door that sets up in the import department again, then be convenient for the animal cage frame from the import department get into inside the disinfection space. The exit operation box arranged on one side of the outlet of the disinfection space is convenient for opening and closing the air sealing door arranged on the outlet, and the animal cage frame convenient for disinfection is separated from the disinfection space from the outlet and enters the closed space for animal experiments.

Of course, the ergonomic control system may also include a main control box 15 disposed on the top wall.

Furthermore, an electromagnetic lock 16 can be arranged between the airtight door and the inlet, and an electromagnetic lock is arranged between the airtight door and the outlet, so that the locking control of the airtight door at the inlet and the outlet is facilitated, and the door locking reliability is ensured.

In addition, the air outlet pipe can be provided with a check valve 42 to effectively prevent air from flowing back through the air outlet pipe to pollute the internal environment of the air inlet pipe, the air outlet pipe and even the disinfection space.

It can be understood that when the chemical sterilization generating module releases the sterilizing gas into the sterilization space, or the air inlet duct feeds the external air into the sterilization space, the air pressure inside the closed sterilization space is gradually increased. Preferably, we can arrange a corresponding sterile relief valve 17 on the sterile space.

When the air pressure in the disinfection space rises to exceed the set value, the air can be released outwards through the disinfection pressure release valve, so that the proper air pressure is maintained in the disinfection space.
