In this embodiment, the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 are magnetic conductive metal sheets, and other sheet bodies capable of generating electromagnetic induction may be used.
In the implementation of the embodiment, the electric heating type killing unit 100 is placed in the magnetic field to work; under the action of a magnetic field, the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 generate an eddy current, and the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 are rapidly heated to a high-temperature working section; the airflow is deflected in the air duct 130, viruses in the airflow are in high-temperature contact with the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120, and the viruses and bacteria in the airflow are inactivated.

It should be noted that the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 are preferably provided in the same configuration for simplifying the configuration and facilitating connection between the both ends of the air duct 130, and are not intended to limit the present invention. In addition, the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 are staggered by 90-180 degrees, so that airflow is bent and flows in the air pipe 130, germs in the airflow can be killed and disinfected with the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 through high temperature staggered twice, and the germs can be killed and disinfected more thoroughly.

To facilitate the flow of the air flow, the present embodiment may provide a blower fan on the side of the air inlet 140 to blow air into the killing device 200, or provide an induced air fan on the side of the air outlet 150 to induce the air flow into the labyrinth duct of the killing unit 100.

It can be seen that, in the present embodiment, the air duct 130, which is a side wall of the killing unit 100, on one hand, when it is of an electromagnetic induction structure, it can also be heated to the working temperature quickly to perform the killing function, on the other hand, it is configured to perform the reinforcing function, so as to resist a part of the air pressure and avoid the too large air pressure from damaging the installation sleeve 210.
In the embodiment, the power supply heating circuit 230 enables the induction coil 220 to generate a magnetic field, so that the first electromagnetic induction sheet 110 and the second electromagnetic induction sheet 120 generate an eddy current, and the temperature is rapidly increased to a high-temperature working section to kill viruses. The killing units 100 of the present embodiment may be a set or multiple sets, when the killing units 100 are multiple sets, the multiple sets of killing units 100 are uniformly arranged inside the mounting sleeve 210, the air flow enters from the air inlet 140 at the end of the air duct 130 and flows in the air duct 130 in a turning manner, and the flow path of the air flow in the air duct 130 can be determined by the staggered angle of the adjacent killing units 100 and the shapes of the air inlet 140 and the air outlet 150, and can be adjusted according to different killing requirements. The groups of killing units 100 may share one group of induction coil 220 and power supply heating circuit 230, or each group of killing units 100 may be provided with corresponding induction coil 220 and power supply heating circuit 230.

The arrangement of the limiting member 260 and the arrangement of the locking groove 250 of the protruding rib 240 limit the axial movement and rotation of the air pipe 130, thereby maintaining the flow path of the air flow and ensuring the killing effect of the air flow.
In one embodiment, the insulation layer 270 is disposed around the mounting sleeve 210, and the insulation layer 270 is disposed between the mounting sleeve 210 and the induction coil 220.
