Hereinafter, when the first outer casing 20 and the second outer casing 30 are collectively referred to, they are simply referred to as "housing CS". The overall shape of the outer casing of the electronic cigarette 1 is formed into a cylindrical shape (rod shape). In the present specification, the term "casing" refers to a casing that houses various components of the electronic cigarette 1, and may be referred to as, for example, a "sleeve" or a "casing".

Further, at the upper end of the first outer casing 20, a first intake hole 26 which is a slit for introducing the outside air into the inside is provided.

Next, the smog part 3 will be described. The smog part 3 series heater unit and the cassette part are integrated. The second outer casing 30 of the smog portion 3 is, for example, a sleeve having a bottomed cylindrical shape, and a suction port 31 belonging to the suction hole is bored in a central portion of the upper end surface 30a. The smog part 3 has a nozzle, and the smoker picks up the upper end side of the second outer casing 30, whereby the aerosol generated in the smog part 3 can be sucked from the suction port 31. In addition, the haze department The end side of the suction port of 3 can also be formed into a tapered shape toward the upper end side in such a manner that the smoker can easily squat.

A second engagement portion 32 for detachably attaching the smog portion 3 and the main body portion 2 is provided on the lower end side of the second outer casing 30 in the smog portion 3. The second engaging portion 32 of the smog portion 3 can engage and disengage the first engaging portion 25 of the main body portion 2. The engagement means of the first engagement portion 25 of the main body portion 2 and the second engagement portion 32 of the smog portion 3 is not particularly limited, and in the present embodiment, a screw connection method is employed. However, a known connection means such as a connection through a sleeve member, such as a fitting connection, may be employed instead of the screw connection. Further, as shown in Fig. 2, a second intake hole 37 which is a slit for introducing the outside air into the inside is provided at the lower end portion of the second outer casing 30. The second intake hole 37 is in communication with the first intake hole 26 of the main body portion 2 in a state in which the smog portion 3 is attached to the main body portion 2, and the air intake port AI is formed by combining these.

Next, the internal structure of the smog part 3 is demonstrated in detail. The inside of the second outer casing 30 of the smog portion 3 is a double cylinder structure, and the cylindrical portion 34 is partitioned into the inner space of the second outer casing 30 by the cylindrical partition wall 33, and the inner passage 39 is provided. . In the cassette portion 34, a liquid supply member 38 such as a cotton fiber impregnated with an aerosol generating liquid is disposed. In addition, the aerosol generating liquid is a liquid which generates an aerosol by heating, and in the present embodiment, a polyol containing a fragrance is used, but it is not particularly limited. For example, it may be a mixture of glycerin, propylene glycol, nicotine solution, water, perfume, and the like.

Reference numeral 35 is a wick that directly or indirectly sucks the aerosol-forming liquid stored in the cassette portion 34 and holds it. Oil absorption The string 35 is, for example, a fiberglass yarn to be knitted. The oil absorbing rope 35 has a capillary structure, and the aerosol generating liquid stored in the cassette portion 34 is directly sucked by capillary action, or is impregnated into the cassette portion through the liquid supply member 3 made of cotton fibers. The aerosol generating liquid of 34 is indirectly absorbed and held. Further, the oil absorbing rope 35 is held by the partition wall 33 in a state in which one of the partition walls 33 is inserted through the holding hole (not shown). As shown in Fig. 3, the oil absorbing rope 35 is stretched across the cross section of the inner passage 39, and both end portions thereof extend toward the inside of the box portion 34, and are in a liquid supply member composed of cotton fibers. Set under 38 contact conditions.

Further, as shown in Fig. 3, an electric heater 36 having an electric heating coil is wound around the oil absorbing rope 35. The oil absorbing rope 35 also functions as a core material for supporting the electric heating coil of the electric heater 36. The electric heater 36 is at least partially surrounded by the center portion in the longitudinal direction of the oil absorbing rope 35. When the electric heater 36 is actuated by energization, the oil absorbing rope 35 is heated, and as a result, the aerosol held on the oil absorbing rope 35 is maintained. The resulting solution evaporates.

Here, the electronic control unit 22 and the battery 21 are connected via electrical wiring, and the electronic control unit 22 controls the energization of the electric heater 36 from the battery 21. Here, the electronic cigarette 1 detects the suction (suction) of the mouthpiece (sucking port) 31 by the smoker by the suction detecting sensor 23 disposed in the main body unit 2, whereby Smoking requirements for smokers are detected. For example, when the smoker sucks the suction port 31, the outside air is introduced into the inside of the outer casing CS from the air introduction port AI. According to the pressure change inside the outer casing CS at this time, the suction detecting sensor 23 can detect the suction of the suction port 31 by the smoker. When detected by the suction detecting sensor 23 When the suction of the mouth 31 by the smoker is performed, the electronic control unit 22 supplies power from the battery 21 to the electric heater 36, and heats the oil absorbing rope 35 to evaporate the aerosol generating liquid.

Further, as for the suction detecting sensor 23, a pressure sensitive sensor or a thermal type flow meter (MEMS flow sensor or the like) that detects a negative pressure generated by a smoker's suction may be used. . Further, instead of the suction detecting sensor 23, a smoking switch (not shown) that accepts an operation by a smoker may be provided in the outer casing CS of the electronic cigarette 1. At this time, the smoking open relationship is connected to the electronic control unit 22 via the electric wiring, and the electronic control unit 22 detects that the smoking switch is operated in the on state. When the smoking switch is turned on, the electronic control unit 22 evaporates the aerosol generating liquid by energizing the battery 21 to the electric heater 36.

Further, as shown in Fig. 2, a second intake hole 37 which is a slit for introducing the outside air into the inside is provided at the lower end portion of the second outer casing 30. The second intake hole 37 communicates with the first intake hole 26 of the main body portion 2 while the mist portion 3 is attached to the main body portion 2, and the members are combined to form an air introduction port AI. .

As described above, when the electronic cigarette 1 detects the suction of the mouth 31 by the smoker, the electric heater 36 is energized to heat the oil absorbing rope 35, and the aerosol generated by the oil absorbing rope 35 is generated. The liquid evaporates (gasification). Further, the smoker sucks the suction port 31, whereby the air that has flowed into the casing from the air introduction port AI is introduced into the inner end of the internal passage 39 in the smog portion 3. The outer end of the inner passage 39 is provided with a suction port 31, and the air flowing into the inner passage 39 is directed toward the suction port 31 and flows through the internal passage. Road 39. Here, as shown in FIG. 3, the oil absorbing cord 35 for holding the electric heater 36 is placed across the internal passage 39 in the middle of the internal passage 39. When the smoker sucks the suction port 31, the aerosol generating liquid which is heated (vaporized) by heating the oil absorbing rope 35 by the electric heater 36 is mixed with the air flowing through the internal passage 39 to generate an aerosol. As described above, the aerosol generated in the internal passage 39 is introduced into the suction port 31 through the internal passage 39, and the smoker can absorb the aerosol from the suction port 31.

The electronic cigarette 1 configured as described above heats the aerosol generating liquid belonging to the flavor generating source held by the oil absorbing cord 35 by the electric heater 36, so that a large amount of heat is generated by the electric heater 36 The circumstances of the issue. Here, when a large amount of heat is suffocated inside the casing CS, there is a possibility that the components housed in the casing CS, for example, the electronic control unit 22 or the aerosol generating liquid stored in the cassette portion 34 are affected. Therefore, the outer casing CS of the electronic cigarette 1 of the present embodiment has a structure in which the heat generated by the electric heater 36 is easily dissipated to the outside.

Hereinafter, the heat dissipation structure of the electronic cigarette 1 will be described. As shown in FIGS. 1 to 3, the outer peripheral surface of the outer casing CS in the electronic cigarette 1 is provided with a concave-convex pattern BP made of metal for promoting heat dissipation. The concavo-convex pattern BP is composed of a plurality of protrusions 5 that are regularly arranged on the outer peripheral surface of the outer casing CS. Fig. 4A is a conceptual diagram showing the outer peripheral surface of the outer casing CS of the electronic cigarette 1 of the first embodiment. Fig. 4B is a perspective view showing the projection 5 provided in the outer casing CS of the electronic cigarette 1 of the first embodiment. In the present embodiment, the projection 5 constituting the concavo-convex pattern BP has a quadrangular prism shape as shown in FIG. 4B, and may have a modification as exemplified in FIGS. 5A and 5B. Other shapes. Fig. 5A illustrates a projection 5 having a cylindrical shape. Fig. 5B illustrates a projection 5 having a bell shape (bowl shape).

Further, the reference numeral 6 shown in Figs. 1 to 3 shows the outer peripheral wall of the outer casing CS. The plurality of protrusions 5 constituting the concavo-convex pattern BP are protruded from the outer peripheral surface 6a of the outer peripheral wall 6 of the outer casing CS. Further, as is apparent from Fig. 1 to Fig. 3, a metal concave-convex pattern BP is provided on the outer peripheral surface 6a of the outer casing CS at least at the position (range) where the electric heater 36 is disposed. In other words, in the electronic cigarette 1 of the present embodiment, a metal concave-convex pattern BP is disposed on the outer peripheral surface 6a of the outer casing CS so as to cover the side of the electric heater 36. Here, by providing the uneven pattern BP on the outer peripheral surface 6a of the outer casing CS, the surface area of the outer casing CS, that is, the heat radiating area can be appropriately increased. Further, by forming the concavo-convex pattern BP as a metal having excellent heat conductivity, heat dissipation by the concavo-convex pattern BP can be promoted.

As a result, it is difficult to suffocate the heat inside the outer casing CS in the electronic cigarette 1, and it is possible to suppress the adverse effect on the aerosol generating liquid of each component housed in the outer casing CS, for example, the electronic control unit 22 or the cassette portion 34. According to the present embodiment, since the plurality of protrusions 5 are disposed on the outer peripheral surface 6a of the outer casing CS, the uneven pattern BP is formed. Therefore, while the heat inside the outer casing CS is appropriately radiated, the holding electrons can be held. The contact area of the finger of the smoker of the cigarette 1 with the outer peripheral surface 6a of the outer casing CS is reduced. Thereby, it is possible to exert the effect that heat is hardly transmitted to the fingers of the smoker holding the electronic cigarette 1, and it is not easy to cause discomfort to the smoker.

Here, in the longitudinal direction of the outer casing CS, the section in which the uneven pattern BP is formed is referred to as "concave-convex pattern arrangement section Z1" (refer to the first Figure). In the present embodiment, the electric heater 36 is disposed at the center portion in the longitudinal direction of the concave-convex pattern arrangement section Z1. As a result, in the longitudinal direction of the electronic cigarette 1 (the outer casing CS), the concave-convex pattern BP can be uniformly distributed around the position where the temperature is most likely to become high, and the heat generated by the electric heater 36 can be efficiently dissipated. To the outside (in the atmosphere). Therefore, it is possible to make heat more difficult to suffocate in the outer casing CS of the electronic cigarette 1. Further, the material for forming the uneven pattern BP (protrusion 5) may be made of metal, and is not particularly limited, but may be, for example, stainless steel or aluminum.

Here, the rate of increase in the heat radiation area (surface area) generated by providing the uneven pattern BP on the outer peripheral surface 6a of the outer casing CS is calculated. In the case of the condition, the diameter of the electronic cigarette 1 (outer diameter of the outer peripheral wall 6 of the outer casing CS) is set to 10 mm, the concave-convex pattern arrangement section Z1 is set to 30 mm, and the shape of the protrusion 5 is set to a cube of 1 side and 1 mm. When the size of the adjacent protrusions 5 separated from each other is 1 mm, the rate of increase in the heat radiation area (surface area) is about 202%. In the present embodiment, when the increase rate of the surface area of the outer casing CS which is formed by providing the uneven pattern BP (protrusion 5) on the outer peripheral surface 6a of the outer casing CS is 20% or more, it is preferable from the viewpoint of heat dissipation.

Here, in the outer casing CS of the electronic cigarette 1, the end on the side where the suction port 31 is provided is referred to as "sucking end 3a". In the present embodiment, the electronic cigarette 1 is formed in a predetermined section from the mouth end 3a in the longitudinal direction of the outer casing CS, and a concave-convex pattern non-arrangement section Z2 in which the uneven pattern BP is not provided is formed (see FIG. 1). Thus, by not arranging the concavo-convex pattern BP in the region on the side of the suction port end 3a of the outer casing CS, when the smoker is licking the suction port 31 of the electronic cigarette 1, the mouth can be prevented from coming into contact with the concavo-convex pattern arranged in the outer casing CS. The metal concave-convex pattern BP of the outer peripheral surface 6a of the section Z1 is set. Further, although the length of the uneven pattern non-arrangement section Z2 is not particularly limited, it is preferably 20 mm or more. That is, since the concave-convex pattern BP is not provided in the interval of at least 20 mm from the suction end 3a of the outer casing CS, it is possible to effectively prevent the smoker's lips from coming into contact with the concave-convex pattern BP when the electronic cigarette 1 is next.

Further, in the electronic cigarette 1 of the present embodiment, as shown in Figs. 4 and 5, the height dimension HS of the projections 5 of the uneven pattern BP is preferably larger than the width dimension WS. By making the height dimension HS relatively larger than the width dimension WS of the protrusion 5, the surface area (heat dissipation area) of the outer casing CS generated by providing the uneven pattern BP on the outer peripheral surface 6a of the outer casing CS can be further improved. increase. Therefore, heat in the outer casing CS in the electronic cigarette 1 can more easily dissipate heat toward the outside.

Further, as described above, by making the height dimension HS larger than the width dimension WS of the projection 5 of the uneven pattern BP, the side surface (side portion) 5b of the projection 5 can be made (see FIGS. 4 and 5). The area (hereinafter referred to as "side area SS") is relatively larger than the area of the top surface (top portion) 5a of the protrusion 5 (see FIG. 4 and FIG. 5) (hereinafter referred to as "top area ST"). That is, the ratio of the side area SS to the entire surface area of the protrusion 5 can be made large. Thereby, when the smoker holds the electronic cigarette 1, the contact area between the finger and the protrusion 5 can be made small, and the heat of the protrusion 5 is harder to be transmitted to the finger of the smoker. Further, as described above, by making the ratio of the side area SS to the entire surface area of the protrusions 5 large, it is possible to preferentially dissipate heat from the side faces 5b of the protrusions 5. Thereby, the temperature of the top surface 5a of the protrusions 5 becomes difficult to become high, and it is less likely to cause an uncomfortable feeling to the smoker who holds the electronic cigarette 1.

Further, as shown in FIG. 5B, when the protrusion 5 of the concave-convex pattern BP has a tapered shape toward the top surface (top) 5a, when the smoker holds the electronic cigarette 1, the smoker's finger and the protrusion 5 can be made. The contact area becomes smaller. Therefore, the heat of the protrusion 5 can be made more difficult to convey to the smoker's finger.

Further, in the electronic cigarette 1 of the present embodiment, it is preferable that the heat insulating material 7 is provided on the top surface (top portion) 5a of the projection 5 constituting the uneven pattern BP (see FIG. 5A). The heat insulating material 7 provided on the top surface 5a of the projections 5 constituting the uneven pattern BP may be, for example, a heat insulating coating material (heat insulating coating material). The heat insulating property of the top surface 5a of the protrusion 5 can be improved by applying a heat insulating coating or the like to the top surface 5a of the protrusion 5. Thereby, the heat generated by the electric heater 36 is preferentially dissipated from the side surface 5b of the projection 5 to the outside in the outer casing CS, and the situation in which the top surface 5a is heated can be actively suppressed. Therefore, the heat of the protrusions 5 is more difficult to conduct to the fingers of the smoker, and the feeling of discomfort to the smoker can be appropriately suppressed. In addition, the type of the heat insulating coating of the top surface 5a of the coating protrusion 5 is not particularly limited, and examples thereof include a coating material in which a ceramic having high heat insulating properties is emulsified (the fine particles are emulsified and mixed).

Further, in the electronic cigarette 1 of the present embodiment, the plurality of projections 5 are regularly arranged at a predetermined interval on the outer peripheral surface 6a of the outer casing CS, but the invention is not limited thereto. For example, the plurality of protrusions 5 arranged on the outer peripheral surface 6a of the outer casing CS may be spaced apart from each other by a certain interval. Fig. 6 is a view showing the electronic cigarette 1A according to the first modification of the first embodiment. The electronic cigarette 1A shown in Fig. 6 is arranged in the central region Z1a of the concave-convex pattern arrangement section Z1 at the point where the electric heating coil of the electric heater 36 is placed, and Figs. 1 to 3 In the same manner as shown in the figure, in the central region portion Z1a of the concave-convex pattern arrangement section Z1 and the end region portion Z1b located on both sides thereof, the intervals (pitch) between the projections 5 are changed.

In the example shown in Fig. 6, the interval between the projections 5 in the central region portion Z1a of the concave-convex pattern arrangement section Z1 is set to be smaller than the interval between the projections 5 in the end region portion Z1b. Thereby, in the concavo-convex pattern arrangement section Z1 of the outer casing CS, the projections 5 can be arranged at a higher density than the end portion region Z1b on the side closer to the central region portion Z1a. Thereby, since the central region Z1a corresponding to the position where the electric heater 36 is disposed in the concave-convex pattern arrangement section Z1 in the outer casing CS, the arrangement density of the projections 5 can be set to the highest, and thus the electric heater 36 can be taken. The heat is more appropriately radiated to the outside.

The preferred embodiments of the present invention have been described above, but those skilled in the art to which the invention pertains can exhibit various modifications, improvements, combinations, and the like. Easy to know. For example, the electronic cigarette 1 of the above-described first embodiment may be used to store an aerosol generating liquid in a form in which the liquid supply member 38 made of cotton fibers or the like is disposed in the cassette portion 34, but may be used in the form of an aerosol generating liquid. The liquid tank stores a tank type of the aerosol generating liquid, and constitutes an atomizer and a liquid tank for evaporating the aerosol generating liquid, respectively. In the above-described embodiment, the example in which the projections 5 are formed in a pattern shape by the outer peripheral surface 6 of the outer peripheral wall 6 of the outer casing CS of the electronic cigarette 1 is described as a concave-convex pattern BP. However, the present invention is not limited thereto. herein. For example, the concave portion may be applied by, for example, cutting processing or the like on the outer peripheral surface 6a of the outer peripheral wall 6 of the outer casing CS. The concave and convex pattern BP is formed by being recessed in a pattern shape. At this time, a plurality of concave portions may be recessed at a predetermined interval on the outer circumferential surface 6a of the outer casing CS. At this time, the protrusions 5 are formed between the adjacent concave portions, and the concave-convex pattern BP is formed by the combination of the concave portions and the protrusions 5.

Further, as in the electronic cigarette 1B of the second modification shown in Fig. 7, the tobacco cassette 8 for accommodating the tobacco leaves may be disposed in the rear stage of the cassette portion 34 in the smog portion 3. Fig. 7 shows only the side of the haze portion 3 in the electronic cigarette 1B only partially. The front end face 8a and the rear end face 8b of the tobacco cassette 8 are configured to pass the aerosol generated by the mist portion 3. The aerosol generated in the mist portion 3 flows into the tobacco cassette 8 from the distal end surface 8a. Further, the smoker can absorb the aerosol of the tobacco component or the fragrance component while the aerosol passes through the tobacco cartridge 8 from the rear end face 8b. Even in the electronic cigarette 1B of this type, by using the heat dissipation structure similar to that of the first embodiment, the heat generated by the electric heater 36 can be appropriately radiated to the outside.

Furthermore, the present invention is also applicable to the electronic cigarette shown in Fig. 8. Fig. 8 is a view showing the electronic cigarette 1C of Modification 3. Fig. 8 is a cross-sectional view showing the cylindrical electronic cigarette 1C cut along the longitudinal direction thereof. The electronic cigarette 1C includes a battery 101, a storage tank 103 that houses the tobacco filler 102, an electric heater 104, and a nozzle 105. The tobacco filler 102 is filled in the storage tank 103, and the tobacco filler 102 in the storage tank 103 is heated by the electric heater 104 to generate an aerosol and to be sucked from the nozzle 105. In the example shown in Fig. 8, the concave-convex pattern BP including the plurality of protrusions 5 made of metal is also provided on the outer peripheral surface 6a of the outer casing CS where the electric heater 104 is disposed. By this, it can be appropriately The heat generated by the heater 104 is radiated to the outside.
