DETAILED DESCRIPTION

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] like Figure 1 As shown, an experimental animal disinfection transfer cabinet of the utility model comprises a cabinet body 10 with a cabinet door 12, a partition 16 is arranged in the cabinet body 10 for dividing the cabinet body 10 into a disinfection chamber and an instrument room, two side walls in the disinfection chamber are arranged with two fixing strips 18, a plurality of recessed holes are opened on the fixing strips 18, brackets 20 are embedded in the recessed holes, a grid frame 22 is placed on the bracket 20, handles are arranged on both sides of the grid frame 22 for easy carrying, the grid frame 22 is used for placing items to be disinfected, and an ultraviolet lamp 24 is arranged on the side wall of the disinfection chamber.

[0019] The bracket 20 can be embedded through the concave hole on the fixing strip 18, and the embedding position of the bracket 20 can be adjusted according to the height of the object to be sterilized, thereby improving the utilization rate, and the ultraviolet lamp 24 can play a role in sterilization.

[0020] A generator 30, an air supply fan 26 and a liquid storage bottle 28 are provided in the instrument room. The generator 30 and the air supply fan 26 are both connected to the top of the disinfection chamber. The generator 30 and the liquid storage bottle 28 are connected through a pipeline, and a peristaltic pump (not shown in the figure) is provided on the pipeline.

[0021] The peristaltic pump delivers the disinfectant in the liquid storage bottle 28 to the generator. The compressed gas introduced into the generator 30 can break up the disinfectant into particles with a diameter less than 10 microns and spray them into the disinfection chamber for disinfection. The disinfectant can be hydrogen peroxide or the like.

[0022] The top of the disinfection chamber is provided with a receiving chamber 38 which is in communication with the generator 30 and the air supply blower 26, and a plurality of through holes 40 are provided on the chamber wall between the receiving chamber 38 and the disinfection chamber.

[0023] The through holes 40 in the accommodating cavity are evenly distributed, so that the particles of the disinfectant can evenly enter the disinfection cavity, effectively improving the sterilization distribution and enhancing the disinfection effect.

[0024] A circulating fan 32 is provided in the instrument room, the air inlet end of the circulating fan 32 is connected to the bottom of the disinfection chamber, and the air outlet end of the circulating fan 32 is connected to the top of the disinfection chamber.

[0025] The circulating fan 32 can circulate the disinfection particles entering the disinfection chamber, thereby improving the disinfection effect and saving materials.

[0026] An exhaust fan 34 is provided in the instrument room, one end of the exhaust fan 34 is connected to the bottom of the disinfection chamber, and the other end is connected to the outside through a residual exhaust pipe, and an exhaust high-efficiency filter 36 is provided on the residual exhaust pipe.

[0027] The exhaust fan 34 can exhaust the residual gas in the disinfection chamber, and the exhaust high-efficiency filter 36 can filter the exhausted gas to avoid polluting the external environment.

[0028] The air supply fan 26 , the exhaust fan 34 and the circulation fan 32 are all provided with sealing valves (not shown in the figure), and the cabinet door 12 is provided with a viewing window 14 .

[0029] Usage process:

[0030] (1) Open the cabinet door 12 on one side, place the items to be sterilized on the rack 22, and close the cabinet door 12;

[0031] (2) The sterilization method to be selected is based on the items to be sterilized: ultraviolet sterilization, cold hydrogen peroxide cycle sterilization, or both. The irradiation time of the ultraviolet lamp 24 and the cold hydrogen peroxide generator 30 are both controlled by a time relay. Relay control is well known in the art and will not be described in detail.

[0032] (3) After the disinfection is completed, open the cabinet door 12 on the other side to take out the disinfected items, and then close the cabinet door.

[0033] The specific process of cold hydrogen peroxide sterilization mode is as follows:

[0034] A. The peristaltic pump rotates forward to transport hydrogen peroxide from the hydrogen peroxide storage bottle 28 to the cold hydrogen peroxide generator 30. The cold hydrogen peroxide generator 30 sprays the sterilant at a high speed and can quickly reach the far end of the space; a small amount of hydrogen peroxide can be dry-atomized to meet the disinfection requirements, thereby improving the disinfection time efficiency and the disinfection quality.

[0035] B. The closed valve of the exhaust fan 34, the inlet valve of the circulating fan 32 and the outlet valve of the circulating fan 32 are opened, and the circulating fan 32 works, and the dry mist hydrogen peroxide is continuously sent into the inner cavity through the circulating pipe to form an internal sterilization cycle; the uniformity of the hydrogen peroxide concentration in the internal space can be improved, so that the fully loaded sterilized items on each layer of the grid 22 can be fully contacted with the dry mist hydrogen peroxide.

[0036] C. The airtight valve of the exhaust fan 34, the inlet valve of the circulating fan 32 and the outlet valve of the circulating fan 32 are closed, so that the dry atomized hydrogen peroxide in the cavity can diffuse freely, and the peristaltic pump is reversed to make the hydrogen peroxide liquid remaining in the generator 30 and the pipeline return to the hydrogen peroxide storage bottle 28.

[0037] D. The airtight valve of the exhaust fan 34 and the airtight valve of the air supply fan 36 are opened, the air supply fan 36 and the exhaust fan 34 are working, the dry mist hydrogen peroxide passes through the exhaust high efficiency filter 36, and then is discharged through the exhaust fan.
