The present invention will now be described in detail with reference to the drawings.

FIG. 2 is an exploded view showing the opening/closing structure of the fine particle generator according to one embodiment of the present invention.

The open/close structure of the fine particle generator according to the embodiment of the present invention is such that the cigarette holder 200 is coupled in the main body 100 and the flip door 300 installed at the upper end of the cigarette holder 200 opens the cigarette in the cigarette holder 200 . Opens and closes the cigarette storage space.

The cigarette holder 200 comprises a holder part 210 having an inner diameter corresponding to the outer diameter of the cigarette, and a connecting part 220 for mounting the flip door 300 and connecting with the main body 100 . The main body 100 is provided with a hole 110 to be coupled with the coupling part 220 of the cigarette holder 200 inside, and the cigarette holder 200 is inserted into the hole 110 . At this time, in order to prevent and fix the body 100 and the cigarette holder 200 to each other, one or more connecting protrusions 224 are formed on the outer circumference of the upper side of the cylindrical connecting part 220 . In addition, the hole 110 of the main body 100 is provided with a coupling groove 112 extending outwardly from the cylindrical hole 110 so as to be coupled with the coupling protrusion 224 .

A rectangular hole 222 is formed on the upper surface of the coupling portion 220 of the cigarette holder 200 for installing the flap door 300 . The hall 222 is opened and closed by a pair of flap doors 310,320. The flap doors 310 , 320 are provided with rotating shafts 312 , 322 on the outer sides, respectively, and rotate about the rotating shafts 312 , 322 such that the flap doors 310 , 320 move into the hole 222 to open the hole 222 . A groove 226 for fixing the rotating shafts 312 and 322 is formed on the upper surface of the coupling portion 220 of the cigarette holder 200 .

On the other hand, a pair of flap doors 310 and 320 are installed with permanent magnets 330 having opposite polarities. Therefore, normally, the flap doors 310 and 320 are kept closed due to the attractive force between the permanent magnets 330 .

Also, a pair of electromagnets 400 are installed in the main body 100 . The electromagnet 400 comprises a core 410 extending so that both ends are located near the rotational axes 312, 322 of the flap doors 310, 320, and a coil 420 wound on the core 410. As shown in FIG. The main body 100 has receiving grooves 120 for fixing both ends of the iron core 410 on its outer surface. A DC current is applied to the coil 420 to magnetize the iron core 410, and the flap doors 310, 320 are opened while an attractive force acts between both ends of the magnetized iron core 410 and the permanent magnets 330 installed on the pair of flap doors 310, 320. 320 is opened.

At this time, the permanent magnets 330 are arranged so that their polarities are opposite to each other. For example, if the polarities of the permanent magnets 330 installed on one flap door 310 are S at the top and N at the bottom, the polarities of the permanent magnets 330 installed on the other flap doors 320 are N at the top. , the lower end of which is the S pole. At this time, the current direction of coil 420 is determined such that the polarity of both ends of iron core 410 is opposite to the polarity of the lower end of permanent magnet 330 that is in close proximity. That is, when a current flows through the coil 420 of the electromagnet 400, the direction of the current is determined so that an attractive force acts on the permanent magnets 330 installed on the flap door 310 adjacent to both ends of the iron core 410. FIG.

FIG. 3 is a diagram showing an electromagnet provided in the opening/closing structure of the fine particle generator according to one embodiment of the present invention, and FIG. It is a graph which shows an H curve.

As described above, a pair of electromagnets are provided. For convenience, the electromagnet shown on the left side is called the first electromagnet 412 and the electromagnet shown on the right side is called the second electromagnet 414 . The iron cores of the first electromagnet 412 and the second electromagnet 414 have a circumferential section around which the coils 422 and 424 are respectively wound, and end portions 412a and 412b that are bent at right angles from both ends of the circumferential section and extend upward. , 414a, 414b. As shown, adjacent core ends have current flowing through coils 422, 424 such that adjacent ends (412a and 414a, 412b and 414b) are copolar to each other. Adjacent ends 412a, 412b, 414a, 414b of each iron core should have the same polarity in order to increase the strength of the electromagnetic force so that the flip door can be opened automatically when the electromagnet is activated. It is something that makes

Meanwhile, referring to FIGS. 2 and 3, both ends 412a, 412b, 414a, and 414b of each iron core are preferably installed adjacent to the outer sides of flap doors 310 and 320 different from each other. That is, for convenience, in FIG. The ends 412b, 414b of the second flap door 320 are positioned adjacent to the outside thereof.

On the other hand, even if current does not flow through the coils 422 and 424 of the electromagnets, the internal magnetic flux density is not zero because residual magnetic flux remains in the iron core due to heat loss (hysteresis loss). At this time, in order to prevent the flap doors 310 and 320 from maintaining the open state due to the attractive force of the residual magnetic flux of the iron cores of the electromagnets 412 and 414 due to the internal residual magnetic flux, both ends 412a of the iron cores of the electromagnets 412 and 414, It may be desirable to adjust the extension length of 412b, 414a, 414b. As the length of the core ends 412a, 412b, 414a, 414b increases, the attractive force with the permanent magnet 330 (see FIG. 2) installed in the flap door increases. It is desirable to form the lengths of 414a and 414b so as not to be too long.

After that, when current is passed through the electromagnet, the difference between the magnetic flux values at the time of ON/OFF becomes smaller due to the influence of the internal residual magnetic flux. Roll it up so that the value of H increases.

FIG. 5 is a cross-sectional view showing an open state of the flap door of the opening/closing structure of the fine particle generator according to one embodiment of the present invention.

When the electromagnets are operated, that is, when the flip doors 310 and 320 are opened, the magnitude relationship between the magnets 331 and 332 installed on the flip doors 310 and 320 and the electromagnets is as follows. is. The magnetic field of the electromagnet and the attractive force between the magnets 331 and 332>the attractive force between the magnets 331 and 332 of the flip door>the internal residual magnetic flux of the iron cores 412a and 412b of the electromagnet and the attractive force between the magnets 331 and 332, if the magnitude becomes smaller in this order. There must be.

Since the attraction between the magnetic field of the electromagnet and the magnets 331 and 332 is the largest, the attraction between the magnets 331 and 332 of the flip door is overcome, and the magnets 331 and 332 installed on the flip doors 310 and 320 attract the magnetic field of the electromagnet. is opened by

At this time, the attractive force between the magnets 331 and 332 installed on the flip doors 310 and 320 can be obtained by Coulomb's law.

and
The attractive force between the electromagnet and the magnets 331, 332 is

is.

For example, the magnet 331 disposed on the left flap door 310 is polarized so that the upper end is the S pole and the lower end is the N pole, and one end 412a of the iron core near the left flap door 310 is magnetized to the S pole. be. Therefore, an attractive force acts between the left end 412 a of the iron core and the lower end of the magnet 331 arranged on the left flap door 310 . The magnet 332 disposed on the right flap door 320 is polarized so that the upper end is the north pole and the lower end is the south pole, and the one end 412b of the iron core near the right flap door 320 is magnetized to the north pole. be. Therefore, an attractive force acts between the right end 412 b of the iron core and the lower end of the magnet 332 located on the right flap door 320 . When the electromagnets are actuated, the sum of the attractive forces between the electromagnets and the magnets 331, 332 located on the flap door and the attractive forces between the internal residual magnetic flux and the magnets 331, 332 due to hysteresis losses is the magnets 331, 332 greater than the gravitational pull between Therefore, when the electromagnets are activated, the attractive force between the magnets 331,332 is overcome and the flap doors 310,320 are opened.

FIG. 6 is a cross-sectional view showing a closed state of the flap door of the opening/closing structure of the fine particle generator according to one embodiment of the present invention.

An attractive force acts between the magnets 331 and 332 arranged on the pair of flap doors 310 and 320 attached to the wall surface, and internal residual magnetic flux remains at both ends 412a and 412b of the iron core of the electromagnet. On the other hand, since no current flows through the coil of the electromagnet and no magnetic field is generated, the induced magnetic field of the electromagnet and the attractive force between the magnets 331 and 332 are zero. Therefore, in order for the flap doors 310 and 320 to maintain the closed state due to the attractive force between the magnets 331 and 332, the attractive force between the magnets 331 and 332 must be greater than the internal residual magnetic flux (hysteresis loss) at both ends 412a and 412b of the iron core. It has to be even bigger.

On the other hand, in order to prevent the flap doors 310, 320 from maintaining the open state due to the attraction between the magnets 331, 332 arranged on the flap doors 310, 320 and the internal residual magnetic flux of the iron cores of the electromagnets, the electromagnets When the operation is finished, the coil is energized in the opposite direction so that the magnets 331 and 332 of the flip doors 310 and 320 are repulsed for a predetermined period of time, and then the current is cut off.

For example, when the electromagnet is turned on, a current flows through the coil of the electromagnet for 1 minute.In addition, at the end of operation, a current flows in the coil for 0.5 seconds in the opposite direction to the current in the electromagnet operating state. can be embodied in circuits and elements to create a repulsive force between the magnets 332, 334 contained in the flip doors 310, 320 and the electromagnets. As a result, it is possible to prevent development in which the flip doors 310 and 320 are kept open due to internal residual magnetic flux after the operation of the electromagnet is terminated.
