For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] As described in the background technology: a large-system circulation disinfection method is used in high-level biosafety laboratories, but this large-system circulation disinfection method in the related art has the problems of inconvenient equipment maintenance, large equipment size, and occupying more space in the machine room. The designer of the utility model found in the research that the reasons for the above technical problems are: the usual fan and heating device are two devices, which are separately installed on the air duct. If maintenance is required, it is necessary to go to the front of the two devices for maintenance, which is very inconvenient, and the two devices are large in size and occupy more space in the machine room. Therefore, the embodiment of the utility model provides a biosafety disinfectant heating circulation integrated fan, which can effectively improve the problems of inconvenient maintenance and occupying more space in the machine room.

[0052] See also Figure 1 The biosafety disinfectant heating and circulation integrated fan 10 provided in the embodiment of the utility model is applied to a high-level biosafety laboratory, and is used to circulate the air in the laboratory, thereby circulating the disinfectant, and heating the disinfectant. The type of disinfectant is not specifically limited, and can be determined according to the specific needs of the laboratory. The disinfectant can be a biosafety disinfectant, and as an example, a hydrogen peroxide disinfectant can be used.

[0053] The biosafety disinfectant heating circulation integrated fan 10 provided in the embodiment of the utility model comprises a housing 100, a partition 200, a fan 300 and a heating device 400. Among them, the housing 100 comprises a fan chamber 110 and a heating chamber 120 connected to each other, the fan chamber 110 is provided with an air inlet 111, and the heating chamber 120 is provided with an air outlet 121. The partition 200 is connected to the inner wall of the housing 100 and divides the housing 100 into the fan chamber 110 and the heating chamber 120, and the partition 200 is provided with a hole 210. The fan 300 is arranged in the fan chamber 110. The heating device 400 is arranged in the heating chamber 120, and the air outlet duct 310 of the fan 300 is connected to the heating device 400 through the hole 210.

[0054] It should be noted that in the biosafety disinfectant heating circulation integrated fan 10, the air inlet 111 can be connected to the air outlet of the laboratory through a pipeline, and the air outlet 121 can be connected to the air inlet of the laboratory through a pipeline, so that the biosafety disinfectant heating circulation integrated fan 10 and the laboratory form an air circulation, and the disinfectant can circulate between the biosafety disinfectant heating circulation integrated fan 10 and the laboratory. When the biosafety disinfectant heating circulation integrated fan 10 is working, the disinfectant enters the fan chamber 110 from the air inlet 111, and through the negative pressure gravitational effect of the fan 300, the disinfectant can be blown out from the air outlet duct 310 of the fan 300 to the heating device 400, and the heating device 400 performs heat exchange on the disinfectant, so that the disinfectant is raised to a preset temperature, and then blown out to the laboratory through the air outlet 121.

[0055] In addition, the box body 100 can be considered as an integrated structure, which is separated by the partition 200, so that the fan chamber 110 and the heating chamber 120 can be considered as an integrated structure, that is, the fan 300 and the heating device 400 are combined into one device.

[0056] Therefore, the biosafety disinfectant heating and circulation integrated fan 10 is formed by arranging the fan 300 in the fan cavity 110 and the heating device 400 in the heating cavity 120. The fan cavity 110 and the heating cavity 120 are separated by the partition 200 to form the box body 100. In this way, the fan 300 and the heating device 400 are integrated in the same device, which can simultaneously meet the functions of driving the disinfectant to circulate and heating the disinfectant, which can greatly improve the convenience of maintenance of the fan 300 and the heating device 400 and greatly save on-site space.

Since the fan 300 and the heating device 400 are integrated into the same device, the fan 300 and the heating device 400 can be easily repaired by opening the first inspection door 510 and the second inspection door 520.

[0061] It should be noted that the movable connection structure between the first access door 510 and the fan chamber 110 can be a sliding connection or a rotating connection, that is, the first access door 510 can be slidably arranged in the fan chamber 110, so as to slide open or close the first access door 510, or the first access door 510 can be hinged to the fan chamber 110, so as to rotate open or close the first access door 510. Similarly, the movable connection structure between the second access door 520 and the heating chamber 120 can be a sliding connection or a rotating connection, that is, the second access door 520 can be slidably arranged in the heating chamber 120, so as to slide open or close the second access door 520, or the second access door 520 can be hinged to the heating chamber 120, so as to rotate open or close the second access door 520. In this embodiment, as an example, the first access door 510 is hinged to the fan chamber 110, and the second access door 520 is hinged to the heating chamber 120.

[0071] In addition, in an optional embodiment, the heating device 400 is an electric heating device or a heating coil. It should be noted that the heating device 400 adopts an electric heating device or a heating coil, both of which can heat the disinfectant well. If the heating device 400 adopts an electric heating device, in order to ensure that the hydrogen peroxide disinfectant can be heated to a suitable temperature in an environment with different temperatures, the electric heating device adopts a 1:2:4 ratio graded control, that is, the electric heating device 400 has three gears, and the heating power ratio of each gear is 1:3:7 respectively.
