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 water heater supercharging device with the filtering function comprises a shell, a supercharging water pump and a filter element, the supercharging water pump is arranged in the shell, the filter element is connected with a water inlet pipe, a middle pipe is connected between the supercharging water pump and the filter element, the supercharging water pump is connected with a water outlet pipe, and the water outlet pipe is connected with a water inlet pipe. A filter element base is arranged in the shell, the water inlet pipe and the middle pipe are located on the filter element base, the top position of the filter element is fixed in the filter element base, the booster water pump can improve the pressure of water, in addition, the filter element can filter impurities in water, scale in the heater is reduced, the service life of the water heater is prolonged, and normal use of the water heater is improved.

The invention relates to the technical field of concrete curing, and particularly discloses a concrete curing kiln which comprises a curing chamber. The buffer chamber is arranged on one side of the curing chamber; the cleaning mechanism is arranged in the buffer chamber and comprises a fan, a filter and a negative pressure pipe, the air inlet side of the fan is connected with the filter, the filter is connected with the negative pressure pipe, the negative pressure pipe comprises a transverse pipe and vertical pipes fixedly connected to the two ends of the transverse pipe, the two ends of the transverse pipe are communicated with the two vertical pipes respectively, and the two ends of the transverse pipe are communicated with the two vertical pipes respectively. Suction inlets are formed in the sides, close to each other, of the two vertical pipes and the side, close to the vertical pipes, of the transverse pipe, so that when a concrete test piece passes through the space between the two vertical pipes, dust on the surface of the concrete test piece can be sucked into the filter through the suction inlets in the negative pressure pipe. The surface of the concrete test piece before curing can be conveniently cleaned, so that the influence of dust on the subsequent curing process is weakened.

The utility model relates to the technical field of water purifiers, and particularly discloses a water purifier with microbubbles, which comprises a bubble water branch, the bubble water branch comprises a first water inlet electromagnetic valve, a composite filter element, a first connecting piece, a bubble water assembly, a bubbler module and a booster pump; the first water inlet electromagnetic valve is in waterway connection with the composite filter element, the composite filter element is in waterway connection with the first connecting piece, the bubble water assembly comprises an air inlet electromagnetic valve and a water-air mixing module, the first connecting piece is in waterway connection with the water-air mixing module, the water-air mixing module is in waterway connection with the bubbler module, and the booster pump is in waterway connection with the water-air mixing module. The air inlet electromagnetic valve is installed on the water-air mixing module, the water-air mixing module is provided with an air inlet hole, and the air inlet hole is communicated with the air inlet electromagnetic valve. According to the water purifier, the blasting effect of microbubbles is utilized, the cleaning capacity is enhanced, pesticide residues and bacteria on the surface of food are effectively removed, and the problem that an existing water purifier does not have the function of removing the pesticide residues and the bacteria is solved.

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.
