ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is in the field of utilization of natural resources of sunlight and water to attract and kill mosquito.
In the whole contents of presented specifications and claims, the term of “a group of solar cells” means a number of solar cells which is from one to any greater number, and the term of “a group of rechargeable batteries” means a number of rechargeable batteries which is from one to any greater number.
Previous invented devices and current market available products of mosquito control use variety of approaches to attract mosquitoes. Carbon dioxide, octenol, and infrared are common mosquito attraction sources in these previous patented devices and current products in market. Using high voltage electric grid to kill mosquito is a kind of common practice in these patented devices and current products. However, processes of usage of these invented devices and current products present certain disadvantages in the aspects of convenience, cost, safety, and environment. When these invented devices and current products are to be used, to obtain the required carbon dioxide, a substance such as. propane has to be purchased in a specific place and has to be burned in use; to obtain the octenol, a can of compressed octenol has to be purchased in a specific place; and to obtain the infrared, an electrical heating device and associated outdoor electrical cord and outdoor electrical outlet have to be used. Although using solar cell to power electric grid of mosquito killing are mentioned in previous patents, how to use solar cell effectively and efficiently and how to use solar cell to power the electric grid beyond the limit of daytime in a mosquito killing system still keep challenging.
Sunlight and water are the most conveniently and economically obtainable environment friendly natural resources for most people in residential areas. Solely using natural resources of sunlight and water in an apparatus to attract and kill mosquitoes in a convenient and economical way should result in a mosquito control device that would provide more advantages in the aspects of convenience, cost, safety, and environment than the previous invented devices and current products in market do. Solely utilizing natural resources of sunlight and water to perform functions of mosquito attraction and killing in ingenious ways is the pursuit of this presented invention.
BRIEF SUMMARY OF THE INVENTION
Sunlight and water are the most conveniently and economically obtainable natural resources for common people. Sunlight and water are the most environment friendly natural resources to be used by common people. Building mosquito attraction and killing apparatus solely based on natural resources of sunlight and water to perform functions of mosquito attraction and mosquito killing is the fundamental goal of the present invention. The followings are the specific goals of mosquito attraction apparatus and mosquito killing system. For mosquito attraction apparatus, sunlight and water are to be synthetically and complementarily utilized; the physical form of the apparatus is to be simple to be manufactured; and the physical form of the apparatus is to be ingenious to be used conveniently. For mosquito killing system, the system is to continuously perform mosquito killing function with the energy of sunlight; the system is to perform mosquito killing function during both daytime and nighttime or other sunlight insufficient conditions with the energy of sunlight; and the mosquito killing system is to be integrated with the mosquito attraction apparatus to form a complete mosquito attraction and killing system that is solely based on natural resources of sunlight and water to perform functions of mosquito attraction and mosquito killing and is conveniently used and manufactured.
The present invention includes two parts of a complete mosquito attraction and killing system. The first part is sunlight and water utilized compound mosquito attraction apparatus. The second part is energy efficient sunlight powered mosquito killing system. The combination of the first part and the second part of the invention forms a complete mosquito attraction and killing system that solely utilizes natural resources of sunlight and water to perform its functions of mosquito attraction and mosquito killing.
The sunlight and water utilized compound mosquito attraction apparatus comprises two major parts. For the convenience of description, the first major part of the sunlight and water utilized compound mosquito attraction apparatus is called multi-function solar utilizer and the second major part of the sunlight and water utilized compound mosquito attraction apparatus is called standing water container.
The multi-function solar utilizer has three basic characteristics in structure and material. The first characteristic is that the lower part of the multi-function solar utilizer is capable of containing liquid, such as water. The second characteristic is that on the upper part of the multi-function solar utilizer, there are a number of small holes which are channels to release both inner gaseous molecules and inner infrared radiation to the outside of the multi-function solar utilizer. The third characteristic is that the outer surface of the multi-function solar utilizer is of dark color, such as black.
The standing water container has one basic characteristic in structure and material. The characteristic is that the wall of the standing water container is transparent so that upper surface of contained water can be seen from outside. The transparent wall of the standing water container does not allow mosquitoes to directly contact with the contained water.
The multi-function solar utilizer and the standing water container are connected together to form the sunlight and water utilized compound mosquito attraction apparatus. The preferred, but not limited, physical form of the sunlight and water utilized compound mosquito attraction apparatus combined by the above two major parts is a column with the multi-function solar utilizer as the upper part and the standing water container as the lower part.
The mosquito attraction apparatus performs the following six functions of mosquito attraction.
1. The multi-function solar utilizer transforms sunlight into infrared radiation, which is released through the small holes, with temperature characteristic of human beings and birds to attract mosquitoes.
2. The multi-function solar utilizer transforms sunlight into infrared radiation, which is released through the small holes, with spectrum characteristic of water to attract mosquitoes.
3. The multi-function solar utilizer utilizes sunlight to produce gaseous state water, which is released through the small holes, to attract mosquitoes.
4. The multi-function solar utilizer utilizes sunlight to create a warm object in the seasons of early spring and late fall to attract mosquitoes.
5. The multi-function solar utilizer utilizes sunlight to spread optional chemical attractant molecules, which are released through the small holes, to attract mosquitoes.
6. The standing water container visually exposes water to the outside to attract mosquitoes.
Besides the individual effect of each mosquito attraction function above, the synthetic effect of multiple factor interaction on the mosquito is more effective and efficient than the simple summation of the individual effect. Synthetic action on mosquito is one of the major advantages of the sunlight and water utilized compound mosquito attraction apparatus.
The process and mechanism of operation of the mosquito attraction apparatus are described as the followings.
Water is added into the multi-function solar utilizer and the standing water container. In accordance with thermodynamics in physics, both inside the multi-function solar utilizer and the standing water container, water exists in both liquid state and gaseous state, and water in liquid state and water in gaseous state reach a corresponding point on the equilibrium curve of phase of water under certain temperature a
