  ELECTRONIC AIR PURIFYING AND NEGATIVE ION GENERATING DEVICE CUM ILLUMINATOR
 
  The present invention is a photo-electronic air purifying, negative ion
  generating and illuminating device, powered by alternating current.
 
  This is an innovative design in this kind of photo-electronic air purifying
  and negative ion generating cum illuminating device.
 
  As this 3-in-l tri-functional invention is assembled with a rifled air duct
  and an extreme-UV light tube, air trapped inside is disinfected in 3 to 6
  seconds, where several types of germs, bacteria and mould etc are
  annihilated. Air is also freshened upon negative ionisation. The device is
  also equipped with lighting facility.
 
  The invention, which is a photo-electronic air purifier, negative ion
  generator as well as an illuminator, comprises: a fan, an extreme-UV light
  tube, cathodic high-voltage carbonized fibre, a remote control and a
  fluorescent tube. When air is drawn into the device, it starts to work in
  two alternating modes. The On mode involves the process of the illumination
  of the extreme-UV light tube which operates for about 8 hours to eliminate
  the germs, bacteria and mould in the air, which is then ionised by the
  electricity produced by the high-voltage cathodic carbonized fibre. The
  anions generated are then blown out by the fan. Following immediately is the
  Off mode which runs for about 4 hours when the extreme-UV light is
  extinguished and the ionisation process is triggered by the electricity
  generated by the high-voltage cathodic carbonized fibre. There is an air
  inlet and an air outlet on the device, where an extreme-UV light tube and a
  cathodic high-voltage carbonized fibre are anchored respectively. The fan,
  which is situated inside the device, draws in untreated air through the
  inlet into the system, from where it is forced through the photo-electronic
  disinfecting unit into the discharge unit via a rifled barrel. By going
  through the extreme-UV light tube, the air is effectively disinfected and
  subsequently ionised by the negative ion generator. Fresh air is then
  finally discharged through the outlet. Consequently the air quality indoors
  is improved. The fluorescent tube mounted on the device serves the purpose
  of illumination.
 
  This mains-powered 3-in-l system can be turned on and off by an external
  switch on the device or operated by a remote control, by which all its
  functions are controlled.
 
  The system is housed in a case in the form of a square column.
 
  A non-limiting embodiment of this invention will now be described with
  reference to the accompanying diagrammatic drawings.

  of the present invention.

  This photo-electronic air purifying and negative ion generating device cum
  illuminator, comprising a housing in the form of a square column or tube,
  has an air draft unit 2, which is situated on the top of the housing 1 at
  its end. At the front of the housing 1, there is an air inlet unit 3.
  Ionised air is released through the air draft unit 20 2.
 
  FIG. 2 shows a schematic diagram of the photo-electronic air purifying and
  negative ion generating device cum illuminator. Air is drawn through air
  inlet unit 3, where the air filter assembly of a fixed sash 4, a dust filter
  5 and a dust cap 6 is mounted. A fan 7 is fixed directly adjacent to the air
  draft unit 2. Mounted on the 25 surface and in the middle of the same unit 2
  is a carbonized fibre 8, through which a cathodic voltage is sent and air is
  ionised. At the end of the housing 1, there is a shutter 23 affixed by two
  screws which can be loosened to remove the shutter for easy replacement of
  the extreme-UV light tube 20.
 
  On the top of the housing 1, there is an electricity box 9 which supplies
  steady power for an electronic generator 10, a commutator 11 and a power
  cable 12. Two metallic hooks 22 on the top of the electricity box 9 are for
  the purpose of hanging the device on the ceiling or the wall. Two
  landholders 13 are integrated into the underside of the housing 1, and each
  receives the ends of a fluorescent tube 14. A transparent protective cover
  15 serves as a shield for the fluorescent tubes 14.
 
  There are two LEDs 16 on the side of the housing, one of which lights up in
  different colours to indicate the mode the diode 17 is in while the other is
  an infrared 5 receiver 24 which works in conjunction with the remote control.
 
  When at work, the fan 7 in the system draws untreated air into the housing
  through the filter 5, which is then trapped in front of an arresting or
  retarding wall or structure 18 comprising many revolving propellers 19
  (generally helical ribs) arranged in a way similar to that in a rifled
  barrel so as to create a rifled air duct. This is to facilitate the air flow
  and to reduce the speed at which the air travels along the arresting or
  retarding wall into air draft unit 2. The extreme-UV light tube 20 is
  located in the centre of the arresting wall 18. Such an arrangement allows
  the disinfection of the air by the extreme-UV light emitted by the tube
  while the air is drawn through air inlet 21 and flows through the revolving
  propellers 19 in the arresting wall 18 into the extreme-UV light tube. See
  the dashed-line air flow in FIG. 2 showing how the generally helical ribs 19
  cause the air to spiral around and along the UV light tube 20. The
  disinfected air is then drawn by the fan 7 into the air draft unit 2, where
  it is ionised and purified by the cathodic high-voltage carbonized fibre 8
  prior to being released as fresh anionic air. The air quality indoors is
  therefore enhanced.
 
  The system utilises an AC power supply, which feeds into a high-voltage
  negative ion generating circuit, resulting in a high negative voltage
  output. The power input is regulated by the system‘s full wave rectifier
  circuit and speed control circuit before being utilised by the fan 7 and
  converted from DC into AC to power the full wave rectifier circuit in the
  extreme-UV light tube. Some of the DC current is diverted, via the voltage
  regulator circuit, to the negative ion generating circuit / extreme-UV light
  tube 20 so as to power the automatically controlled circuit, by which the
  anion generator and the extreme-UV light tube are operated.
 
  By increasing the amount of anions in the air in an indoor environment, our
  body undergoes an enhanced rate of biochemical reactions, which reduces the
  level of hormonal secretion to combat depression and tiredness. Extreme-UV
  light is effective in the sterilisation of germs, bacteria and mould in the
  air, while the lighting facility provided by the system is an added asset in
  modern day life.
 
  The device uses an extreme-UV light tube to emit an ultraviolet light at the
  wavelength of 253.7 nanometres, which is effective in eliminating bacteria,
  germs and mould. The negatively charged ions generated help purify and
  freshen the air. The lighting facility in the device is an added asset in
  terms of meeting modern day 5 requirements in illumination. The device
  therefore serves well in most households, hospitals, residential homes,
  department stores, cinemas, restaurants, offices, workshops, elevators,
  vehicles, ships, airplanes and trains. This 3-in-l invention, which combines
  the functions of photo-electronic air purification, negative ion generation
  and illumination, will improve the environments in our homes, hospitals, 10
  offices, shops and transportation. It also helps to revitalise air quality
  amidst the constant destruction of our natural environment.
