If inserted, the sensor 150 generates accordingly electric signals.
  • Also, the inner pipe 120 is formed with a plurality of hexagonal openings 121H, 121L. The hexagonal openings 121H, 121L are formed long in the longitudinal direction of the inner pipe 120 for 3 openings to be placed in a staggered way on the upper and lower parts, respectively, along the circumference of the inner pipe 120. Here, preferably, the length of the openings 121L formed on the lower part of the inner pipe 120 is greater than that of the openings 121H formed on the upper part thereof. The reason for the greater length of the openings 121L on the lower part than that of the openings 121H on the upper part is because, when air is sucked in the fan 180, the air flows downward and more dust taken from the duster 1 can thus pass through the openings 121L on the lower part than the openings 121H on the upper part. The closed lower end of the inner pipe 120 is shaped a cone whose vertex is oriented toward the upper part of the pipe 120. The reason of the cone-shaped lower part of the inner pipe 120 is to induce air flowing in the longitudinal direction of the inner pipe 120 to flow in all directions along the lower side of the conical shape, in order to reduce noise occurring in the inner pipe 120.
  • On the outer side of the inner pipe 120 constructed as such, as seen in FIGS. 2 and 4, 3 air separators 125 are fixed to be long in the longitudinal direction of the inner pipe 120 spaced by 120° along the circumference. The air separators 125 guide the air flowing out of the openings 121H, 121L to flow it downward. If there are not provided the separators 125, the air from the openings 121H, 121L collides in the space between the inner pipe 120 and the outer pipe 130 thus to form turbulence. However, since the air separators 125 are fixed between the openings 121L on the lower part, the air passing through the openings 121H, 121L flows downward along the air separators 125. Therefore, turbulence is not formed to significantly reduce noise, and it is possible to prevent the dust collected in the filter 190 from floating by means of turbulence. The air separators 125 which function as such have a plurality of through holes 127 in a longitudinal direction. The through holes 127 in one air separator 125 are not placed at the same level as those in another air separators 125 and are thus formed in a staggered way one another.
  • In the meantime, the inner pipe 120 is placed on the inner side of the outer pipe 130. The upper parts of the inner pipe 120 and the outer pipe 130 are closed by a closing plate 140. The closing plate 140 has the same diameter as that of the outer pipe 130, and has a hollow, in the center of the plate 140, having a diameter the same as that of the inner pipe 120. The plate 140 is formed to have a plurality of through holes 141 along the circumference of the closing plate 140. Therefore, the inner pipe 120 and the outer pipe 130 are coupled and thus integrated by means of the closing plate 140.
  • A step 131 is formed on the lower part of the outer pipe 130 along its circumference. The step 151 formed on the holder 150 is engaged with the step 131 on the outer pipe 130. Therefore, the body 110 can stand on top of the holder 150 for storage.
  • On one side of the holder 150, a filter insertion hole 160 is formed, which has a size in a horizontal direction corresponding to a half of the diameter of the holder 150. Under the filter insertion hole 160, exhaust holes 153 are formed along the circumference of the holder 150. On the inner side of the holder 150, a fan 180 is equipped. The fan 180 is positioned at a place under the filter insertion hole 160 but above the exhaust holes 153. Therefore, when the fan 180 is activated, the air flowing into the space between the inner pipe 120 and the outer pipe 130 through the through holes 141 on the closing plate 140 and the openings 121H, 121L, of the inner pipe 120 passes through the fan 180 and is then discharged to the outside through the exhaust holes 153.
  • In the path where the air moves, the filter 190 is placed.
  • The filter 190 is inserted in the filter insertion hole 160 formed on the holder 150 and then positioned inside of the holder 150, while equipped in the filter holding unit 170.
  • Now, the filter 190 and the filter holding unit 170 will be described.
  • As shown in FIGS. 5 to 7, the filter 190 is one of a cup-shaped HEPA filter or air conditioning filter made of fiber such as non-woven fabric. In case of a non-woven fabric filter 190, an elastic string 191 is fixed at the entrance of the filter 190 which is in turn equipped by fitting the elastic string 191 on the filter fixing unit 170. In case of a HEPA filter not shown, a ring-shaped bracket is fixed around the HEPA filter, and the bracket is embodied to be held on the filter fixing unit 170.
  • Now, as an example, a non-woven filter provided with an elastic string will be described.
  • The filter fixing unit 170 is structured to be shaped a half cylinder cut in half in a vertical direction to open/close the filter insertion hole 160, and comprises a closing/opening plate 171 provided with a grip 173 at the front and a ring 175 fixed to the inner side and on the upper part of the closing/opening plate 171. The ring 175 has a groove 177 formed along its circumference. The elastic string 191 is stretched in the groove 177 so that the filter 190 can be supported to be on the lower part of the ring 175.
  • When such a filter fixing unit 170 configured as described above is inserted in the filter insertion hole 160, the filter 190 is placed under the ring 175, and the air flowing from the upper part toward the lower part of the body passes through the filter 190, fine dust being thus collected in the filter 190.
  • In the meantime, when the filter fixing unit 170 is inserted in the filter insertion hole 160, the ring 175 is placed in the holder 150. In this case, in order for the ring 175 to be stably placed, a stop 155 for supporting the ring 175 is formed on the inner side of the holder 150 along the inner circumference of the holder 150.
  • The holder 150 constructed as described above has a structure to be gradually wider from the upper part toward the lower part, so that it has a stable structure when it stands on a floor. A control unit 101 is equipped inside the holder 150. The control unit 101 operates the fan 180 according to the signals inputted from the infrared sensor 105. It is also possible for a user to operate the fan 180 by means of the input panel 103 equipped on the outer side of the holder 150, independently of the infrared sensor 105.
  • As shown in FIG. 8, it is also possible to sterilize the dust collected in the filter 190 by further providing an ultraviolet lamp, preferably between the lower part of the inner pipe 120 and the filter 190. The ultraviolet lamp 200 operates according to the signal sent from the infrared sensor 105 like the fan 180, or can operate through the input panel 103 equipped on the outer side of the holder 150, independently of the infrared sensor 105.
  • Now, the operation of the dust collector for a duster constructed as described above will be described.
  • While power is supplied to the dust collector, a user inserts the duster 1 in the upper part of the body 110, namely the inner pipe 120 from its top. The infrared sensor 105 then recognizes insertion of the duster 1 and outputs electric signals. The output electric signals are sent to the control unit 101 which in turn operates the fan 180, or both of the fan 180 and the ultraviolet lamp 200 according to the input signals.
  • When the fan 180 starts to operate, the air in the body 110 is sucked toward the lower part where the fan 180 is placed, and then passes through the filter 190 to be discharged to the outside through the exhaust holes 153.
  • After the user puts the duster 1 inside the inner pipe 120 of the dust collector, he turns round the grip of the duster like twirling something with both hands to take off the dust on the bristle of the duster 1. In this case, when the user turns round the duster 1, the bristle on the duster 1 rotates at an accelerated state by means of centrifugal forces and the accelerated and rotating bristle hits the edges of the openings 121H, 121L. That is, rotating the duster 1 inserted in the inner pipe 120 impacts the bristle on the duster 1 to take off the dust on the bristle.
  • Also, if an ultraviolet lamp 200 is provided, germs, ticks, etc., included in the dust are effectively be killed by means of ultraviolet rays.
  • The dust taken off the duster 1 moves along the air flow.
  • Now, the principle of the air flow will be described in detail.
  • When the fan 180 sucks air, the air inside the inner pipe 120 flows between the inner pipe 120 and the outer pipe 130 through the openings 121H, 121L. The air from the outside is led in the space between the inner pipe 120 and the outer pipe 130 through the through holes 141 on the closing plate 140. The air led in the space between the inner pipe 120 and the outer pipe 130 moves downward along the air separator 125, and then passes through the ring 175 of the filter fixing unit 170 to be led in the filter 190. The air led in the filter 190 passes through the filter 190 by means of suction of the fan 180, and the air passing through the filter 190 is discharged to the outside through the exhaust holes 153 on the holder 150.
  • The dust flowing together with the air is collected in the filter 190 on the way through the filter 190 and sterilized by means of ultraviolet rays from the ultraviolet lamp 200.
  • When the duster 1 is pulled out of the inner pipe 120, the infrared sensor 105 senses it and sends a different type of electric signals to the control unit 101. The control unit 101 then interrupts operation of the fan 180, or both of the fan 180 and the ultraviolet lamp 200.
  • The dust taken off the duster 1 is collected in the filter 190 by means of the action of the dust collector 100 for a duster which operates as described above. When the filter 190 is filled with dust, a user can take out the filter fixing unit 170 to remove the dust collected in the filter 190, washing or replacing the filter 190 then easily to install it again.
  • The present invention has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
  • Use of the verb “comprise” and its conjugations does not exclude the presence of elements other than those stated in a claim. The article “a” or “an” preceding an element does not exclude the presence of a plurality of such elements.
  • The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
