The invention belongs to the field of mosquito prevention and killing, and particularly relates to a technology for killing mosquitoes by using a safe and non-toxic alkaline which does not contain pyrethroids and phosphorus. The preparation method comprises the following steps: mixing water, glycol stearate, tetrasodium glutamate diacetate, sodium hydroxide, fatty alcohol-polyoxyethylene ether and polydimethylsiloxane to obtain a mixed aqueous solution, standing, and filtering to obtain a final aqueous solution of the mosquito killer. Strict tests prove that the non-pyrethroid alkaline mosquito killer has a very high killing effect on static and flying mosquitoes by spraying an aqueous solution through a spraying can, is environment-friendly, particularly has no pollution to air when being used in a closed space, and is an ideal non-pyrethroid alkaline mosquito killer. The pyrethroid mosquitocide has a good killing effect on various mosquitoes, and another mosquito killing method except the pyrethroid mosquitocide is provided.

The present application relates to the technical field of object drying, in particular to an electric heat blowing drying device, which comprises a shell and an inner container, the inside of the inner container is provided with a flow guide plate, a fan blade and a heating pipe, further comprising an air adjusting assembly arranged in front of the fan blade and a separation piece arranged at the bottom of the inner container; the air adjusting assembly is rotationally arranged on the side wall of the flow guide plate, the air adjusting assembly has a first air outlet for drying objects and a second air outlet for increasing the gas flow rate, the first air outlet and the second air outlet are moved to the front of the fan blade by rotation; the present application adjusts the air pressure and the air flow rate by arranging two air outlets, before drying, the high flow rate gas generated by the second air outlet blows off the hard water on the surface of the objects, and the separated hard water is isolated by the liquid collecting cavity. During the drying process, the hard water on the surface of the objects is reduced, thereby reducing the generation of scale and reducing the area that needs to be wiped.
