Abstract
A combustible pesticidal product (10) is disclosed which comprises a planar continuous helix (11) in the form of a hexagon having sides (24, 25, 26, 27, 28 and 29). An intersection (20, 22) of each side of the structure has a radius of curvature of 5.0 mm to less than 58.5 mm, most preferably 9.0 to 10.0 mm. Typically the combustible product will be a mosquito coil formed from cardboard which has been impregnated with one or more insecticides effective against mosquitoes. On combustion of the coil, insecticide may be emanated into the atmosphere for a period of up to 24 hours. However, typically the coils of the invention will be active against mosquitoes for 12 hours.
Description
Technical field
Can in air, distribute the combustible product of agricultural chemicals when the present invention relates to burn, more specifically, the product that the present invention relates to prolong burning time, so the efficacy of a drug of this product has also prolonged action time.
Background technology
This series products involved in the present invention is referred to as " mosquito coil " usually.The characteristics that this class is coiled are to form round screw thread by combustible material.Comprise one or more agricultural chemicals in the combustible material, when this product had activity to mosquito, this agricultural chemicals was exactly an insecticide.During this product burning, insecticide is dispersed in the air owing to having volatility.Ideally, this class is coiled the insecticide that can make air have effective dose in the suitably long time.
The environment of use mosquito coil is the place of people's sleep typically, is subjected to biting of mosquito because the people can't eliminate mosquito when sleeping.In addition, baby or some people can not or inconvenience eliminate the mosquito come to bite, at this moment, in its residing environment, also to use mosquito coil.
Understand easily, mosquito is being carried germ, and these germs can cause a large amount of chronic and normally life-threatening diseases, perhaps can cause the weak disease of human body at least.Malaria most serious of all in these diseases.Therefore press for and prevent mosquito bite, so that avoid infection this class disease.
The mosquito of the torrid zone and subtropical zone is especially many, and wherein the national per capita income of certain areas is relatively low.Therefore needing to provide price dog-cheap Pesticidal products.Under usual conditions, common mosquito coil just can satisfy this requirement.This type of mosquito coil contains cheap insecticide, and makes comparatively easily.Owing to only need burning to coil insecticide is distributed, so required unique energy is exactly to ignite with enough heats to coil and make it to burn.Yet this type of is coiled the characteristic that is lacked and is, it can not guarantee the insecticidal activity that provides enough at the whole night of people's sleep.Typically, mosquito coil should have and reaches about 8 hours insecticidal activity.Yet, owing to this is coiled and can break, so it can only burn the very short time usually.This will ask for help and wake up from sleep, find to coil to have stopped burning, rekindle uncracked part then carefully, and the part that also need guarantee simultaneously not break is perfect and install correct.This requirement is unfavorable for keeping at whole night the validity of kill mosquito.
From this view point, it should be noted that common mosquito coil adopts die casting or other manufacturing process to form the planar rondure spiral.Coiling terminal is that approximately central position has a slit, and this slit is used for mosquito coil is placed on the upright pole.This upright pole is erected usually on a dish or dish, and this dish or dish are used for collecting the ashes of coiling after the burning.Coil when being positioned on the pole, this is coiled just lax coming and forms continuous spirality, and the place that the top of coiling promptly takes fire is lower than the terminal that places on the pole.Like this, this continuous spiral has just formed a track, and flare is burned to the terminal that is fixed along the top of outside.
Should be appreciated that also and mosquito coil can be formed the Double Circle spiral.Two spirals of this structure have common terminal.Yet before use, need two spirals are separated from one another.Making a major reason of coiling by this way is, this can save available material, and is convenient to make shaping.
As mentioned above, typically, mosquito coil is broken easily.This is because they are very crisp, and in manufacture process, is not to make planar shaped with coiling, but makes it to be bent to form the structure of wave or projection.Sometimes, leaving end or the point of coiling main body can be bent upwards.Therefore easily understand, make, packing, transportation and when being used by the consumer, coil easy breaking.The consumer when using this to coil, open and installation coil must extreme care.Particularly coil for double helix, separating each must be careful when coiling, so that avoid it to break.Must emphasize also in addition, break that its length will shorten, the most important thing is that also will shorten its burning time in case coil.
Summary of the invention
In view of the above-mentioned shortcoming of traditional mosquito coil, present inventors attempt to provide improved coiling, and described effective desinsection cycle of coiling is longer, and than traditional coil cheap for manufacturing cost.
Inventors recognize, combustible material need be formed polygon helical structure rather than round screw thread structure, thereby they have reached purpose of the present invention.Yet the crucial part that has been found that is that in order to make it continuous burning, the transposition section on every limit must be crooked, and its radius of curvature has certain limitation.
