Mosquito repelling and killing tablet utilizing self-heating of zinc-air microbattery

Abstract

The invention discloses a mosquito repelling and killing tablet utilizing self-heating of a zinc-air microbattery. The mosquito repelling and killing tablet is formed by compounding a zinc-air microbattery self-heating composition and a beta-cyclodextrin-mosquito repelling and killing drug inclusion compound, heat energy generated by primary battery reaction of the zinc-air microbattery self-heating composition is used for promoting release of the mosquito repelling and killing drug, power supply heating or fire source ignition is not needed, and the mosquito repelling and killing drug is safe, efficient, long-acting, convenient to carry and free of environmental pollution.

Description

technical field [0001] The invention belongs to the field of sanitation and insecticide, and in particular relates to a mosquito repelling sheet which utilizes the heat energy generated by the primary battery reaction of a zinc-air micro-battery self-heating composition to heat and volatilize the mosquito repelling drug ingredients. Background technique [0002] Mosquitoes live in summer, which not only affects the normal rest of humans and animals, but also spreads malaria, Malayi filariasis, Bancrofti filariasis, Japanese encephalitis and dengue fever. It is one of the most disgusting pests for human beings. Mosquito coils made of mosquitoes sensitive to certain chemicals are the most commonly used methods for humans to deal with mosquitoes and flies, cockroaches, bedbugs, fleas, ants, dust mites, spiders and other pests. Mosquito-sensitive chemical substances usually include two categories: natural and synthetic. At present, most of the synthetic mosquito-repelling drugs ...

Problems solved by technology

But this type of mosquito-repellent incense has the following main disadvantages: (1) it is a flameless smoldering type of combustion during use, which will produce smog containing ultrafine particles, and may also produce polycyclic aromatic hydrocarbons, carbonyl compounds and other substances that are harmful to human health, especially not applicable For people with asthma; (2) The temperature of the burner is as high as 600-700°C when burning, and a part of the medicine near the burner has no time to volatilize and decomposes when heated, causing the loss of the medicine. At the same time, the decomposition products may also cause harm to the human body ;(3) It needs to be ignited by an open flame. At the same time, if the burner contacts combustibles during use, there is a potential danger of fire

This type of mosquito-repellent incense has no open flame and no smoke when in use, is relatively safe, and is generally welcomed by people, but it also has the following main disadvantages: (1) The use of electric heating mosquito-repellent incense requires power and consumes electric energy (about 5 watts / hour) , and can not be used under the condition of lack of power supply; (2) The temperature of the heating source for heating electric mosquito coils is generally 160-180 ° C. At this temperature, a part of the drug will also be decomposed, which will reduce the utilization rate of the drug and decompose. The product may also endanger human health; (3) The low-boiling solvent used to dissolve the drug in the electric mosquito-repellent incense liquid is heated and volatilized, and when it reaches a certain concentration in an air-circulated or closed space, it will cause harm to the human body. It may cause human diseases; (4) The stabilizers, synergists, volatilization regulators, fragrances and coloring agents added to the electric mosquito-repellent incense sheet and electric mosquito-repellent liquid may also decompose when heated, and the decomposed products may affect Human health; (5) If you forget to disconnect the power after use, there will be safety hazards

This type of sanitary product has the advantages of being convenient to store, carry and use, and quickly repelling mosquitoes, but there are also some disadvantages: (1) the production cost is relatively high; (2) due to the certain pressure in the tank, the organic solvent in the tank Components such as propellant and propellant have the potential danger of leakage, combustion and explosion; (3) the additives, synergists and organic solvents in the tank are sprayed out together with the drug, and if the room is airtight or the air circulation is not smooth, it may Harm to human health to a certain extent
