DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is a portable air conditioning or air purifying unit for persons with health problems due to air quality. These health problems include headache, fatigue, depressions, etc. and possibly some types of allergic and asthmatic reactions as well.
2. Discussion of the Background
To improve air quality there are many devices available. However, most have the common disadvantage of purifying air only in the immediate surroundings without always securing sufficient purification and improvement of air closest to the users head/facial and breathing area.
Even when using expensive stationary air conditioners and purification equipment, users may still breathe polluted and noxious air when for instance cigarette smoke comes between the user and the air purifying unit
Having some health problems due to air pollution, the inventor has been experimenting since 1977 making both stationary and portable air purifiers. He came to the conclusion that he benefited most when using an air purifier dose to his breathing organs. Therefore, he made air purifiers smaller and portable, because other purifiers on the market were stationary and consequently did not solve the health problems mentioned above.
In a German publication, DE 27 33 729 B 2, a stationary air purifier with a combination of ionizer and fan has been presented earlier. This purifier does not solve the above mentioned problems as it is stationary.
The inventor designed several small air purifiers which are portable and use a neck strap. He also designed portable ionizers having certain similar features as those types which were later patented by others, see Norwegian laid-open publication #167246 and international publication #WO 92116251. According to the inventor's experience, none of these ionizers offer a satisfactory solution to health problems like headache, fatigue, and other discomfort related to air pollution. This lack of effect also seems to be confirmed by doctors that have made investigations in this regard. Another disadvantage to ionizers is that they contain a high voltage unit and ere surrounded by an electric field which may cause discomfort to some persons. Short-term use of ionizers is considered acceptable by health professionals, but there are questions concerning long-term effects. Experiments show that long-term use of portable ionizers close to the body may cause discomfort to susceptible persons. The inventor has solved this problem by placing an ionizer to the outside of the main apparatus (FIG. 1) so that the electrical field has less exposure to the body compared with the portable ionizers mentioned above. Also, the inventor has designed additional equipment (optional) in the ionizer, inter alia a pot meter which allows the user to adjust the amount of ionization to fit individual need. In addition thereto, the inventor has an adjustable field regulator in his ionizer, thereby enabling an even greater adaptation to personal need. Also included is a lower belt attachment which stabilizes the ionizer, avoiding the pendulous movements of prior ionizers when walking and in motion.
In areas having variable and poor air quality, the air will normally consist of far more noxious gases and pollutants that can possibly be purified by a simple portable or stationary ionizer, because an ionizer has a limited range of operation. The inventor has for many years constructed and tested prototypes of portable air purifiers, and has come to the conclusion that ionizing alone is usually not sufficient. A more versatile air purification system is necessary to obtain satisfactory results. Obviously, there is a need to focus a multi-filtered stream of air directly to the breathing organs from a short distance, using a speed regulator. Experience shows that this gives the best health results, because the user of such a portable purifier generally gets the health advantages of improved air quality no matter where he is residing. Thus, there should be a clear demand for an apparatus which offe
