Control means 4 for controlling components such as the light emitting means 2 and the heater unit 12 by the electric energy stored in the power storage means 3;
A suction detection means 5 including a diaphragm type switch, for example, which is in an energized state by detecting a pressure change in the power supply unit that occurs when sucked from the mouthpiece 14;
A concentric first electrode portion 6 connected to the control means 4 is provided at the rear end.

  The first electrode portion 6 is insulated from a ventilation hole 61 penetrating along a central axis, one cylindrical electrode 62 disposed outside the ventilation hole 61, and further outside the one electrode 62. The other electrode 63 is provided with an external screw 64. The other electrode 63 has a cylindrical shape.

The heater unit 12 has a second electrode portion 7 at the front end, an electric heater 8 inside, and a protrusion 15 at the rear end.
The second electrode portion 7 is insulated from the air passage 71 penetrating along the central axis, one cylindrical electrode 72 disposed outside the air passage 71, and further outside the one electrode 72. The other electrode 73 having a cylindrical shape disposed with the body interposed therebetween, and an inner screw 74 is formed on the inner surface of the other electrode 73.
Both ends of the electric heater 8 are connected to the one electrode 72 and the other electrode 73.
The air passage 71 passes through the heater unit 12. One end of the air passage 71 communicates with the two intake holes 18 and 19 opened on the outer peripheral surface of the heater unit 12 on the second electrode portion 7 side, and the other end encloses the electric heater 8 and the protruding portion. It opens on the 15 side. The electric heater 8 is disposed in the air passage 71.

  The chemical solution supply means 13 is provided with an aluminum film 16 to be broken by the projection 15 at the front end side, and a breathable filter 17 filled with the chemical solution is incorporated inside, and a mouthpiece 14 is opened at the rear end. ing.

As shown in FIGS. 3 and 4, the light emitting means 2, the power storage means 3, the suction detection means 5, and the first electrode unit 6 are connected to the control means 4.
When the control means 4 is sucked and used as an electronic cigarette,
While controlling the heat generation of the electric heater 8 through the first electrode unit 6 and monitoring the output voltage to the first electrode unit 6 to prevent over-discharge of the storage means 3,
When charging by connecting to the electronic cigarette charging unit 5,
Control is performed so that the charging power supplied from the electronic cigarette charging unit 5 is received via the first electrode unit 6, and the charging means 3 is appropriately charged by monitoring the charging current and the charging voltage. And prevent overcharging.

When used as an electronic cigarette,
Like the electronic cigarette 1 shown in FIG. 1, the power supply part 11, the heater unit 12, and the chemical | medical solution supply means 13 are connected, and it uses with a form like one cigarette. In this state, the aluminum film 16 of the chemical solution supply means 13 is broken by the protrusion 15.
Thus, when used as an electronic cigarette, the electrode for charging the power storage means is not exposed when the heater unit 12 and the chemical solution supply means 13 are connected. Can be used for suction.
When the user sucks with the mouth 14 included in the mouth, the outside air sucked from the suction holes 18 and 19 formed on the outer surface of the heater unit 12 flows through the air passage 71 of the heater unit 12. It becomes.

At this time, the space facing the vent hole 61 of the suction detection means 5 is slightly depressurized by the air flow, so that the suction detection means 5 detects that the suction has been sucked from the suction port based on the change in the generated atmospheric pressure. Then turn on the built-in contact.
In this way, when the contact of the suction detection means 5 is turned on, the control means supplies the electric energy stored in the power storage means 3 to the light emitting means 2 to light it, and causes the first electrode portion 6 to turn on. Supply.
Accordingly, the electric heater 8 connected to the second electrode portion 7 that is also electrically connected to the first electrode portion 6 is energized. Therefore, the air flow is heated by the electric heater 8 and is sucked into the user's oral cavity from the mouthpiece 14 together with the vaporized component of the chemical liquid filled in the filter 17.

When used in this manner, the aluminum film 16 of the chemical solution supply means 13 is broken by the projection 15 provided in the heater unit 12, so that a part of the chemical filled in the filter 17 is part of the projection 15. Since the electric heater 8 is wetted, when the electric heater 8 is energized, the outside air sucked by the generated heat is heated, and a part of the chemical is vaporized to form a mist. It is sucked out from the mouthpiece 14 into the user's mouth.
Therefore, the user can inhale and enjoy the flavor component of the medicinal solution by using the mouthpiece and sucking like a cigarette, or use the medicinal effect. At this time, the light emitting means 2 at the tip lights up in red and looks like a cigarette fire.

When the suction is stopped, the pressure drop in the air passage 71 disappears, so the suction detection means 5 is turned off, and the light emitting means 2 at the tip is turned off. In this way, if you inhale or stop inhaling, it will turn red and the redness will disappear like a real cigarette fire, so it looks natural as if you were smoking real cigarettes.
Furthermore, if you stop sucking and remove the electronic cigarette that you hold from your mouth, the mist-like medicinal solution that has been sucked into your mouth will be expelled from your mouth, making it look like real cigarette smoke.

Next, the case where the electronic cigarette 1 is charged using the case 10 also serving as a charging unit according to the present invention will be described with reference to FIGS.
The case 10 accommodates a plurality of exchangeable chemical supply media (chemical supply means) 13 (for example, six, see FIG. 5 and FIG. 6A) that are used by being attached to the electronic cigarette. It has.
As shown in FIGS. 6B and 6C, the storage unit 20 is formed in a plurality (for example, 6 units), and in addition to inserting the power supply unit 11 of the electronic cigarette when charging. The charging unit 30 and the storage unit 40 having a depth capable of storing the electronic cigarette 1 in the state shown in FIG. 1 as it is are also formed.

In addition, the kind of chemical | medical solution impregnated to the filter 17 of the said chemical | medical solution supply means 13 is not limited to what contains a specific flavor component. Those having various medicinal effects such as medicinal liquids containing various flavor components and medicinal liquids having the effect of suppressing or preventing bad breath can be used.
For example, by adding a health benefit agent to the chemical solution impregnated in the filter 17 so as to obtain an effect of promoting health, mixing a vegetable or animal colorant, and blowing out colorful colored water vapor from the mouth, Various effects such as exhilaration and fashion can be obtained.

  The case 10 further includes a charging circuit 39, which will be described later. The charging circuit 39 appropriately controls the power supplied from the AC power plug 33 or the DC power connector 32, and outputs a charging output. It is configured to supply the first electrode unit 6 of the power supply unit 11 of the electronic cigarette via the electrode 31.

When charging the electronic cigarette 1, the chemical solution supply means 13 and the heater unit 12 are removed from the power supply unit 11 to expose the first electrode unit 6.
The power supply unit 11 with the first electrode unit 6 exposed is inserted into the charging unit 30, and an external screw 64 of the first electrode unit 6 is screwed into the charging output electrode 31, so that one of the first electrode units 6 The electrode 62 and the other electrode 63 are electrically connected to the charge output electrode 31.
Then, the AC power plug 33 is pushed out of the case 10 and inserted into an AC 100 volt outlet, or a low voltage DC is supplied from the DC power connector 32 via the USB cable 90 to supply power to the electronic cigarette 1. The unit 11 can be charged. At this time, charging and completion of charging are indicated by the color of the LED disposed on the side surface of the case 10.

Since the USB cable 90 includes a USB plug 91, by connecting the USB plug 91 to a USB terminal of a personal computer or the like, a low voltage direct current (about 5V) supplied from the USB terminal (V _BUS and GND) can be obtained. The power can be supplied to the DC power connector 32 disposed on the side surface of the case 10 via the output plug 92.

Next, the detailed structure inside the electronic cigarette 1 will be described with reference to FIGS.
Inside the power supply unit 11 of the electronic cigarette 1, electrical components such as the power storage means 3, the control means 4, the light emitting means 2, and the suction detection means 5 and their electrical wirings 41, 42, 43 and the like are housed. Since these electric parts and electric wiring may be damaged by a shock at the time of assembling the electronic cigarette 1 or during transportation, there is a possibility that the quality as a product is lowered.
Therefore, in the electronic cigarette 1 according to the present invention, the electric parts such as the power storage means 3, the control means 4, the light emitting means 2, and the suction detecting means 5 and all or at least a part of the electric wirings 41, 42, 43, etc. Was covered with insulating films 36 and 37.
For example, as shown in FIG. 7, a part of the power storage means 3, the suction detection means 5 and the surrounding electrical wiring are covered with an insulating film 36, and a part of the power storage means 3, the control means 4, and the light emitting means are covered. 2 and the surrounding electrical wiring were covered with an insulating film 37 to be protected. As the insulating films 36 and 37, for example, a heat-shrinkable insulating tube is preferable.
Since the electrical parts and electrical wiring are protected and fixed by the insulating films 36 and 37, the electronic cigarette 1 can be prevented from being damaged by a shock during assembly or transportation, and the quality as a product can be improved. It can be stabilized.

As shown in the cross-sectional view of FIG. 8, the space is secured between the casing and the power storage means 3 by interposing the electrical wires 41, 42, 43, so that the intake hole on the front end side shown in FIG. The outside air sucked from 19 is easily circulated to the mouth 14.
As shown in FIG. 9, when sucked from the suction port 14, an air flow from the intake holes 18 and 19 is generated as shown by the two-dot chain line arrows. This air flow generates a differential pressure in the direction indicated by the thick arrow on the upstream side and downstream side of the suction detection means 5, so that the suction is surely detected and a signal is sent to the control means 4. Can do.

10 and 11 show a USB charging unit having a function of charging the power supply unit 11 of the electronic cigarette 1. FIG. 12 is a circuit diagram of a charging circuit built in a case that also serves as a charging unit.
The USB charging unit 93 includes a USB plug 94, a cable 95, and a charging connector 96, and a charging electrode 97 is formed on the charging connector 96.
By connecting the USB plug 94 to a USB terminal of a personal computer or the like and screwing the power supply unit 11 of the electronic cigarette 1 into the charging connector 96 as shown in FIG. 11, there is no AC 100-volt outlet nearby. If there is a USB terminal such as a personal computer, it can be easily charged.

As described above, the electronic cigarette 1 of the present invention can be charged using the charging unit 10 or the USB charging unit 93 that also serves as the case with the first electrode portion 6 exposed.
Therefore, since the charging unit is compact and not bulky, it is convenient when charging, when not in use, and when carrying.
Furthermore, since the charging unit 9 can be charged immediately if there is a personal computer equipped with a USB port, it is not necessary to search for an outlet under a table or the like and to extend from there using an extension cable. However, it is convenient because it can be charged at any time near the desk where the PC is set.

As the structure for connecting the electrode of the power supply unit 11 and the electrode of the charging unit, an example in which a screw structure is employed in the above embodiments has been shown. However, various structures such as a fitting structure and a magnetic adsorption structure are used. It is possible to connect.
Furthermore, the structure which exposed the electrode part used for charge to the outer peripheral surface of the electronic cigarette 1 is also possible. In this case, since the said electrode part is exposed, a connection with a charging unit becomes easy. In addition, it is natural that the charging electrode of the charging unit in this case is in an appropriate form according to the electrode portion.
The casing of the electronic cigarette 1 has a generally cylindrical shape in order to resemble the appearance of the cigarette, but is not limited to a generally cylindrical shape. It can be manufactured in various shapes such as an overall shape similar to the shape of a vehicle or a vehicle.
Further, the red light emitting means 2 uses a red light emitting diode in order to resemble a cigarette fire when lit, but the light emitting means is not limited to red but is lit in various colors such as blue, white and green. Can also be used.

In the following, an embodiment of the suction detection means will be described with reference to FIGS.
FIG. 13 is a side sectional view for explaining the structure of an embodiment using a reed switch as a suction detection means.
As shown in FIG.
The suction detection means 50 is a circular shape in which a substrate unit 53 having a reed switch 52 disposed on the bottom surface side of a cylindrical spacer 51 is mounted, and a small and spherical magnet 54 is fixed on the top surface side of the spacer 51. The diaphragm 55 is disposed.
The outer diameter of the spacer 51 is set equal to or smaller than the inner diameter of the casing 11 so that the spacer 51 can be disposed in the casing 11.

Both lead wires of the reed switch 52 are soldered to the substrate unit 53.
A notch is formed on the bottom surface side of the spacer 51 so that a bent portion of the lead wire of the reed switch 52 disposed on the substrate unit 53 is fitted, and the bent portion of the lead wire is formed in this notch. It is fixed by fitting.
A step 56 for fitting the diaphragm 55 is formed on the top surface side of the spacer 51, and the diaphragm 55 to which a spherical magnet 54 is fixed can be disposed at a predetermined position. Yes.
The position of the stepped portion 56 is tested in advance so that the reed switch 52 on the substrate unit 53 disposed is turned on and off by the magnet 54 of the diaphragm 55. It is set according to the magnetic force.

The outer diameter of the magnet 54 is preferably about 1.5φ, for example. The material of the diaphragm 55 is preferably a durable material having electrical insulation and heat resistance.
As shown in the figure, it is preferable that the position of the magnet 54 is slightly shifted (for example, 0.8 mm) from the center of the diaphragm 55 so that the reed switch 52 operates reliably.

With reference to FIG. 14, a method of fixing the small spherical magnet 54 to the diaphragm 55 will be described.
As shown in FIG. 14A, the diaphragm 55 is a thin circular film, and a material having insulation and heat resistance may be used.
As shown in FIG. 14B, the N-pole and the S-pole are formed on the small spherical magnet 54 (about 1.5φ), but its position is unknown from the appearance. However, unless the direction of the magnetic field lines is directed toward the reed switch 52, it is difficult to operate the magnetic field reliably.

Therefore, a method of fixing the N pole or S pole of the magnet 54 toward the reed switch side will be described below.
First, when an iron clip 57 or the like is magnetically attracted to the spherical magnet 54, the clip 57 is attracted to the N pole or S pole having the strongest magnetic force in the magnet 54. When the clip 57 is lifted in this state, it can be lifted with the magnet 54 adsorbed.
In this state, since the magnetic pole is directly above one of the magnets 54, the magnetic pole just below is the other magnetic pole, and the direction of the lines of magnetic force is in one of the upper and lower directions.
Therefore, as shown in FIG. 14 (C), the direction of the magnetic lines of force can be changed by lowering and adhering to the predetermined position of the diaphragm 55 from above the diaphragm 55 with the magnet 54 suspended by the clip 57. It can be fixed in a state in which it is oriented in any of the upper and lower directions.
In this way, after the magnet 54 is bonded to the diaphragm 55, it is set on the step portion 56 of the spacer 51 as shown in FIG.

Next, a procedure for setting the diaphragm 55 so that the magnet 54 and the reed switch 52 are in proper positions will be described.
First, before fixing the diaphragm 55 to the spacer 51, the spacer 51 to which the substrate unit 53 is attached is fixed on a jig (not shown), and both terminals of the reed switch 52 are set in a measuring instrument such as a tester. Thus, the on / off state of the reed switch 52 can be confirmed. In addition, the reed switch 52 is in an off state before the diaphragm 55 is set.
Then, the diaphragm 55 on which the magnet 54 is set is set on the step portion 56 of the spacer 51, and the diaphragm 55 is rotated in a state where it is placed on the step portion 56 to find a rotation position where the reed switch 52 is surely turned on. Then, the diaphragm 55 is fixed to the spacer 51 at the rotational position.

Since the suction detection means having the above configuration is used, when the suction mouth 14 of the electronic cigarette 1 is sucked, the diaphragm 55 is sucked and the magnet 54 is separated from the reed switch 52, so that the contact of the reed switch 52 is turned off from on. Change to state. On the basis of this state change, the heater unit 12 is turned on to vaporize the chemical liquid supplied from the chemical liquid supply means 13 and turn on the red light emitting diode 2 to suck in the flavor component and smoke mist. The tip part glows red as if the fire was on.
In the above description, a configuration using a diaphragm, a magnet, and a reed switch has been described as an example of the suction detection unit. However, it is a matter of course that the configuration is not limited to such a configuration.
