Mosquito killer

The invention relates to the technical field of mosquito killers and particularly relates to a mosquito killer comprising a mosquito killer shell. The mosquito killer shell is provided with an air inlet and air outlets and is internally provided with an air suction device and an air internal circulation air passage. The air suction device allows the air in the mosquito killer shell to flow along the air internal circulation air passage to form an air internal circulation air flow. A suction force is generated in the mosquito killer shell through the air suction device, mosquitoes and air at the air inlet of the mosquito killer shell are sucked into the shell through the air suction device, at the same time, under the effect of the air suction device, the air flow forms the air internal circulation air flow through the air internal circulation air passage, and the mosquitoes are effectively trapped to die from the strike of the rotating air suction device or exhaustion.
