To sum up, the mosquito catching device capable of increasing the mosquito catching area provided by the utility model is provided with an installation cavity inside, the installation cavity is provided with a centrifugal fan, the mosquito catching device is provided with a first air inlet respectively communicated with the installation cavity and a first air outlet communicated with the installation cavity, and the first air outlet faces the first air inlet; the air flow blown out of the centrifugal fan to the first air outlet can be blown to the first air inlet, then is sucked from the first air inlet by the centrifugal fan and is blown out of the first air outlet, when mosquitoes are positioned at the first air inlet, the mosquitoes can be sucked into the mosquito catching device through the first air inlet by the centrifugal fan, and when the mosquitoes are positioned between the first air inlet and the first air outlet, the mosquitoes can be carried by the air flow blown to the first air inlet by the first air outlet and are conveyed to the first air inlet, and then are sucked into the mosquito catching device through the first air inlet by the centrifugal fan; the first air outlet arranged towards the first air inlet is additionally arranged around the first air inlet, so that the effective area of the mosquito catching device for catching the mosquitoes is increased, and the capability of the mosquito catching device for catching the mosquitoes is enhanced.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed should be considered illustrative rather than limiting. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. Any changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
