The present invention relates to an air purifier, more particularly to an air purifier which employ UV tube to generate UV with wavelength of 253.7 nanometers, which is able to kill bacteria, virus and mildew in the air while emits negative ions into the environment.
1. Field of Invention
Most conventional air purifiers require normal indoor power supply such as 220V or 120 volt depending on geographical limitation, while few of those are designed mainly for transportation vehicles, which allow air purifier to function under a power supply generated by automobile, i.e. 12 volt, as transportation vehicles are operating. Almost no conventional air purifier has the ability providing capacity for both indoor power supply and automobile power supply.
Numerous air filters have been provided in prior art. For example, U.S. Pat. No. 3,967,927, U.S. Pat. No. 4,210,429; U.S. Pat. No. 5,171,060 and U.S. Pat. No. 5,330,722 all are illustrative of such prior art. While these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
As disclosed in U.S. Pat. No. 3,967,927, an ultraviolet lamp fixture for purifying the air within a room by means of passing the air over a plurality of hot cathode or other commercially available ultraviolet ray tubes. The tubes are mounted vertically within a decoratively covered, easily movable, pole-mounted housing having a motorized fan, which moves air through an opening in the lower portion of the housing over the tubes for purification. The purified air stream is exhausted through the top body portion of the housing and returned to the room. The interior of the housing has deflector vanes which function to create a turbulent airflow in the area of the tubes to insure that contacting the lamps purifies all of the air passing through the lamp fixture. The lamp fixture is provided with means for filtering the circulating air. In an alternate embodiment, the air passes through a dehumidifier prior to passing by the tubes.
Furthermore, U.S. Pat. No. 4,210,429, a room air purifier for quietly removing irritating or harmful impurities from the air circulating within the room. The purifier removes from room air, particles down to 0.3 microns in size with 99.9% efficiency. The air purifier comprises a somewhat elongated upright housing having an easily-removable back, a two-speed blower that is preferably AC operated and disposed at the bottom body of the housing, a pair of vertically disposed ultraviolet lamps and associated means for powering the lamps including push button switch means, and preferably three separate filters including a pre-filter disposed at the inlet of the blower, a highly efficient main filter element vertically stacked over the blower and lamps and a charcoal filter disposed over the main filter element. The blower sucks the air in the bottom body of the purifier through the pre-filter and up adjacent to the lamps to the main filter element and charcoal filter, and from there the purified air passes to a top body baffle cover where the air is exited in preferably four directions from the purifier.
In U.S. Pat. No. 5,171,060, an ornament-displaying article of furniture having a weight-bearing surface member and pedestal base has a supporting substantially cylindrical and preferably transparent column releasable connected to the weight-bearing surface member. The appearance of the column may be altered with an agglomeration or reflective fill material, such as marbles, which may be exchanged by detaching the column from the weight-bearing surface member. In a preferred embodiment a light source irradiates light reflective or light radiant material of the fill.
In U.S. Pat. No. 5,330,722 a germicidal air purifier for trapping and destroying airborne microorganisms is disclosed. The air purifier includes an ultraviolet radiation source and a juxtaposed filter medium. One ultraviolet radiation source and filter medium is fixed and the other is displaceable, so that at least an upstream side of the filter medium is systematically exposed to germicidal levels of radiation. In a first preferred embodiment, a fixed ultraviolet lamp irradiates a cylindrical air filter, which is rotated on its longitudinal axis in close proximity to the lamp, so that the upstream side of the filter is systematically irradiated. In a second preferred embodiment, a radiant lamp fixture is moved reciprocally across an upstream side of a planar filter, to systematically irradiate the filter. In a third preferred embodiment, a radiant lamp fixture is rotated about an axis, which is orthogonal to its longitudinal midpoint, so that a circular area of a planar filter is irradiated. The advantage is that microorganisms trapped on the filters are exposed to a lethal dose of radiation and the air purifier is consistently effective at destroying a significant percentage of airborne microorganisms suspended in the air passed through the filter.
In addition, most conventional air purifiers can only separate unwanted airborne particles from air to achieve so-called purification for air. However, this is a well known fact that anions in the air are good for health. It would be beneficial should air purifiers can produce anions while separating unwanted airborne particles from air allows.
2. Description of Related Arts
A main object of the present invention is to provide an air purifier has the ability providing capacity for both indoor power supply and automobile power supply.
A main object of the present invention is to provide an air purifier which employ UV tube to generate UV with wavelength of 253.7 nanometers, which is able to kill bacteria, virus and mildew in the air while emits negative ions into the environment.
Another object of the present invention is to provide an air purifier can produce anions while separating unwanted airborne particles from air flows.
Accordingly, in order to accomplish the above objects, the present invention provides an air purifier, which comprises:
This present invention has a rectangular shaped body with top body (1) and bottom body (2). It also has an arc shaped air outgoing lattice (3) which is an outlet of ionized air. Referring to
On upper portion of said top body (1) there is a rectangular round hole (10) whereby on/off switch cover (11) is affixed at. At lower portion of said bottom body (2), on/off switch cover (11) is closely glued to a switch (12). Said switch (12) controls various functions of air ventilator (6), an UV emission tube (13) and said carbonization fiber (7). On said upper portion′ surface of said top body (1) there is a round hole (14) to fix different color of illuminating diodes (15), which are used as functional indicators. Said switch (12) and said illuminating diodes (15) are fastened to a photoelectron UV radiation circuit device (21) at said bottom body (2) of said air purifier.
In practice, when activating said air purifier, said air ventilator (6) draws air with bacteria, virus and mildew through dust filtration screen (5), moves them into an air collectors (16) which are inside of said top body (1) and said bottom body (2) of said air purifier. At both front and back ends of said air collector (16), there are many strip frames (17) which guide moving air through air collector (16) to an outgoing air lattice (3). In a center portion of said strip frames (17) there is a blocking wall (18). UV emission tube (13) is located at a center portion of said air collector (16). In other words, air contains bacteria, virus, mildew travels into both front and back ends of said air collector's (16) collecting pockets (18), then moves into an air intake vent (20) which is located between UV emission tube (13) and collecting pockets (16). Therefore when air goes though air intake vent (20), bacteria, virus, and mildew are killed by UV emitted from the UV emission tube (13). Purified air will then leaves via said ventilator (6) to outgoing lattice's (3) negative high voltage carbonization fiber (7) is ionized. At a result, ionized fresh air is released through said outgoing air lattice (3) to improve indoor air quality.
There are blocking wall (18) at both said top body (1) and said bottom body (2) of said air collector (16). Said blocking wall (18) is to prevent emission of UV radiation outside of the appliance and is for protecting the user's eyes.
Said air purifier is having a circuitry theory which receives power from the AC or car battery through the external outlet (9). Input power passes through on/off switch (12) to a circuitry of negative ion generator to provide a negative high voltage output. An output power goes through a rectifier providing power to ventilator (6), and said circuitry that exchange DC and AC, activating circuitry for UV emission tube (13). Another one provides power to negative ion generator and UV emission tube's (13) automatic circulating controlled circuitry, in charge of this operation of negative ion generator and UV emission tube (13).
Negative ion from the generator could promote biochemistry process in human body (by increasing the amount of negative ions break in). When inhaled increased quantity of negative ions, it could lower the hormonal secretion on depression and fatigue.
The present invention uses UV tube to generate UV with wavelength of 253.7 nanometers, which is able to kill bacteria, virus and mildew in the air. In this modern society, air condition is a must appliance for families, hospitals, senior citizen centers, shopping malls, theaters, restaurants, office buildings, production workshops, elevators, different cars, ships, airplanes, and trains. Functions of Photoelectron Sterilization Air Purifier improve the environments of our lives, habitations, medical treatments, work conditions, shopping and transportations etc.; provides us clean spaces in this constant nature demolishing modern society.
