[0005] Patent Document 1: Japanese Patent No. 6552028 Summary of the Invention

[0006] The problem that the invention will solve

[0007] To improve operability when installing the cartridge containing the aerosol source into the cartridge housing, it is envisioned to eliminate the positioning mechanism illustrated in Patent Document 1. However, without the positioning mechanism, the insertion position of the cartridge relative to the cartridge housing will not be fixed. Therefore, maintaining the electrical connection between the cartridge and the cartridge housing and preventing short circuits due to different insertion positions becomes a problem. Furthermore, if the positioning mechanism can be eliminated, it becomes easier to install multiple types of cartridges with different electrode shapes. In this case, maintaining the electrical connection between each type of cartridge and the cartridge housing and preventing short circuits also becomes a problem.

[0008] The purpose of this invention is to provide an aerosol generating device that can maintain and prevent short circuits between the cartridge and the housing even when the insertion position of the cartridge changes or when different types of cartridges are inserted.

[0009] Methods for solving problems

[0010] According to one aspect of the present invention, the power supply unit of an aerosol generating apparatus includes a housing portion that houses a cylindrical cartridge containing an aerosol source. A first electrode portion comprising a plurality of electrodes is provided on the end face of the cartridge. The housing portion has a second electrode portion in a region opposite to the end face. The second electrode portion includes more electrodes than the total number of electrodes contained in the first electrode portion, and each electrode in the first electrode portion is capable of contacting the electrodes contained in the first electrode portion.

[0031] The power supply unit of the aerosol generation apparatus according to one embodiment of the present invention will be described below. First, referring to... Figures 1-3 An aerosol extractor will be described as an example of an aerosol generating apparatus equipped with the power supply unit of this embodiment.

[0032] (Aerosol extractor)

[0033] Aerosol absorber 1 is a device used to absorb aerosols that generate fragrance without combustion, and is preferably of a size that fits in the hand and has a roughly cubic shape. Alternatively, aerosol absorber 1 can also be oval, elliptical, etc. In the following description, in the roughly cubic aerosol absorber, the three orthogonal directions are referred to as the up-down direction, the front-back direction, and the left-right direction in descending order of length. Furthermore, in the following description, for convenience, such as... Figures 1-3 The document defines front, back, left, right, above, and below, with front represented as Fr, back as Rr, left as L, right as R, above as U, and below as D.

[0034] like Figures 1-3 As shown, the aerosol inhaler 1 includes a power supply unit 10, a first cartridge 20, and a second cartridge 30. The first cartridge 20 and the second cartridge 30 are detachable from the power supply unit 10. In other words, the first cartridge 20 and the second cartridge 30 can be replaced separately. Figure 4As shown, the first smoke cartridge 20 is cylindrical in shape. However, the shape of the first smoke cartridge 20 does not have to be perfectly cylindrical. For example, it can be a polygonal shape such as a regular hexagon or a cylindrical shape with rounded corners.

[0035] (Power supply unit)

[0036] like Figure 1 as well as Figure 2 As shown, the power supply unit 10 houses the power supply 12, internal retainer 13, circuit board 60, air intake sensor 15, and various other sensors inside the generally cubic power supply unit housing 11 (hereinafter also referred to as the housing interior). By concentrating the power supply 12, circuit board 60 (including the MCU (Micro Controller Unit) 50, power-on switching circuit 51, resistance measurement circuit 52, resistance measurement circuit 53, resistance measurement circuit 54, protruding electrodes 411, 412, 413, charging terminal 43, etc., described later) within the power supply unit housing 11, it is easy for the user to carry, improving user convenience.

[0037] The power supply unit housing 11 is composed of a first housing 11A and a second housing 11B that can be attached and detached in the left-right direction (thickness direction). By assembling these first housings 11A and second housings 11B in the left-right direction (thickness direction), the front, rear, left, right, and bottom surfaces of the power supply unit 10 are formed. The upper surface of the power supply unit 10 is formed by the display 16.

[0038] An interface tube 17 is disposed on the upper surface of the power supply unit 10, in front of the display 16. For example... Figure 3 As shown, the suction port 17a of the interface tube 17 protrudes upwards more than the display 16.

[0039] An inclined surface that slopes downwards towards the rear is provided between the upper surface and the rear of the power supply unit 10. An operable control unit 18 is provided on this inclined surface. The control unit 18 comprises a button switch, a touch panel, etc. The control unit 18 is used to start / stop the MCU 50 and various sensors in response to the user's intent.

[0040] A charging terminal 43 is provided on the lower surface of the power supply unit 10, which can be electrically connected to an external power source (not shown) that can charge the power supply 12. The charging terminal 43 is, for example, a socket into which a plug (not shown) can be inserted. As the charging terminal 43, a socket into which various USB terminals (plugs) can be used. As an example, in this embodiment, the charging terminal 43 is a USB Type-C shaped socket. As a result, the power supply unit 10 (i.e., the aerosol extractor 1) can be easily charged at various locations, ensuring that the power supply unit 10 can be charged.

[0041] Alternatively, the charging terminal 43 may be configured to have a receiving coil and be able to receive power from an external power source in a contactless manner. In this case, the wireless power transfer method can be electromagnetic induction, magnetic resonance, or a combination of both. As another example, the charging terminal 43 may also be compatible with various USB connectors and have the aforementioned receiving coil.

[0042] The internal retainer 13 includes: a rear wall 13r extending along the rear of the power unit 10; a central wall 13c located in the center of the housing in the front-rear direction and extending parallel to the rear wall 13r; an upper wall 13u extending along the display 16 and connecting the rear wall 13r and the central wall 13c; a partition 13d, orthogonal to the rear wall 13r, the central wall 13c, and the upper wall 13u, dividing the space formed by these rear walls 13r, the central wall 13c, and the upper wall 13u into a left space and a right space; and a cartridge retainer 13a connected to the central wall 13c, located in front of the central wall 13c and above the lower surface of the power unit 10. Figure 2 as well as Figure 3 As shown, the cartridge holder 13a is a bottomed cylindrical component with an opening on the upper end and an axial direction in the vertical direction.

[0043] A power source 12 is disposed in the left space of the internal retainer 13. The power source 12 is a rechargeable secondary battery, a double-layer capacitor, etc., preferably a lithium-ion secondary battery. The electrolyte of the power source 12 may also be composed of one or a combination of a gel electrolyte, an electrolyte solution, a solid electrolyte, and an ionic liquid.

[0044] An L-shaped circuit board 60 is disposed in the space formed by the right side space of the internal retainer 13 and the lower side space formed between the cartridge retainer 13a and the lower surface of the power supply unit 10. The circuit board 60 is constructed by stacking multiple layers (four layers in this embodiment) of substrates and carries electronic components such as an MCU 50.

[0045] The MCU 50 is connected to various sensor devices, such as the intake sensor 15 that detects the suction (intake) action, the operation unit 18, and the notification unit 45. The MCU 50 includes a load 21 (see below) for... Figure 3 The control device (controller) for various controls of the aerosol extractor 1, including the discharge control of the load 21 for heating (generating aerosol), is described. Specifically, the MCU 50 is mainly composed of a processor and also includes storage media such as RAM (Random Access Memory) and ROM (Read Only Memory) for storing various information, which are required for the operation of the processor. The processor in this specification is, for example, an electronic circuit that combines circuit elements such as semiconductor elements.

[0046] like Figure 3 As shown, a cylindrical cartridge holder 14 for holding the first cartridge 20 is disposed on the lower end of the inner periphery of the cartridge holder 13a. The bottom wall portion 13ab of the cartridge holder 13a and the cartridge holder 14 constitute a bottomed cylindrical cartridge receiving portion CS that houses the first cartridge 20. The bottom wall portion 13ab forms the bottom of the cartridge receiving portion CS. The upper surface of the bottom wall portion 13ab forms the bottom surface 13as of the cartridge receiving portion CS.

[0047] The inner periphery of the cartridge holder 14 is shaped to correspond to the outer shape of the first cartridge 20. A small gap is formed between the inner peripheral surface of the cartridge holder 14 and the outer peripheral surface of the first cartridge 20, which is sufficient to allow the first cartridge 20 to rotate slightly in the circumferential direction due to impacts, vibrations, etc. applied to the power supply unit 10.

[0048] Neither the cartridge housing CS nor the first cartridge 20 is provided with a mechanism for circumferentially (around the center line of the first cartridge 20) positioning of the first cartridge 20 within the cartridge housing CS. That is, with the first cartridge 20 housed in the cartridge housing CS, if a force is applied to the first cartridge 20 to rotate it circumferentially, the first cartridge 20 can be rotated 360 degrees.

[0049] A through hole 13b is provided on the bottom wall portion 13ab of the cartridge holding portion 13a. The through hole 13b respectively accommodates the protruding electrodes 411, 412 and 413 (see reference) that protrude from the circuit board 60 toward the first cartridge 20. Figure 3 , 5The protruding electrodes 411, 412, and 413 constitute the second electrode section. The protruding electrodes 411, 412, and 413 are each configured to be electrically connected to the power supply 12, for example, by being a pin with a built-in spring. The through holes 13b, corresponding to the protruding electrodes 411, 412, and 413 respectively, are larger than each protruding electrode and are configured to allow air to flow into the interior of the first cartridge 20 through the gap formed between the through holes 13b and each protruding electrode.

[0050] like Figure 2 As shown, an air intake sensor 15 for detecting inhalation is provided on the outer peripheral surface 14a of the cartridge holder 14, opposite to the circuit board 60. The air intake sensor 15 can also be composed of a capacitor microphone, pressure sensor, etc. A relatively long vertical hole 14b is provided in the cartridge holder 14, allowing visual observation of the remaining amount of aerosol source 22 stored inside the first cartridge 20. Figure 1 As shown, a light-transmitting balance confirmation window 11w is formed in the power unit housing 11. It is configured to allow visual observation of the remaining amount of aerosol source 22 stored inside the first cartridge 20 through the hole 14b of the first cartridge 20 via the balance confirmation window 11w. An air intake 11i is provided in the balance confirmation window 11w for drawing in external air into the housing.

[0051] like Figure 3 As shown, the interface tube 17 is detachably fixed to the upper end of the cartridge holder 14. The second cartridge 30 is detachably fixed to the interface tube 17. The interface tube 17 has a cartridge receiving portion 17b that accommodates a portion of the second cartridge 30 and a connecting passage 17c that connects the first cartridge 20 to the cartridge receiving portion 17b.

[0052] (First smoke bomb)

[0053] like Figure 3 As shown, the first cartridge 20 has inside the cylindrical cartridge shell 27: a storage unit 23 for storing an aerosol source 22; an electrical load 21 for atomizing the aerosol source 22; a core 24 for introducing the aerosol source from the storage unit 23 to the load 21; and an aerosol flow path 25 for the aerosol generated by the atomization of the aerosol source 22 to flow to the second cartridge 30.

[0054] The reservoir 23 is divided around the aerosol flow path 25 and stores the aerosol source 22. Alternatively, the reservoir 23 may contain a porous material such as a resin mesh or cotton, and the aerosol source 22 may be impregnated in the porous material. Alternatively, the reservoir 23 may not contain a resin mesh or cotton-like porous material, and may only store the aerosol source 22. The aerosol source 22 may contain a liquid such as glycerol, propylene glycol, or water.

[0055] The wick 24 is a liquid holding component that uses capillary action to introduce the aerosol source 22 from the reservoir 23 into the load 21. The wick 24 is made of, for example, glass fiber or porous ceramic.

[0056] The load 21 is a heating element (i.e., a heater) that heats the aerosol source 22 without combustion, and is, for example, composed of a heating wire (coil) wound at a predetermined interval. The load 21 atomizes the aerosol source 22 by heating it. As the load 21, heating resistors, ceramic heaters, induction heaters, etc., can be used. The load 21 can also be composed of an ultrasonic element or other element capable of atomizing the aerosol source 22 without heating.

[0057] The aerosol flow path 25 is located downstream of the load 21 and on the center line of the first smoke cartridge 20.

[0058] like Figure 4 As shown, a first electrode portion is provided at the lower end 26 of the cartridge shell 27 of the first cartridge 20, including plate electrodes 261 and 262 electrically connected to the load 21. Plate electrodes 261 and 262 are exposed on the surface 26s of the lower end 26. One terminal of the load 21 built into the first cartridge 20 is connected to the plate electrode 261, and the other terminal of the load 21 is connected to the plate electrode 262. The load 21 is supplied with power from the power supply 12 via two electrodes from the protruding electrodes 411, 412, and 413 on the power supply unit 10 side: one electrode that abuts against and is electrically connected to the plate electrode 261, and the other electrode that abuts against and is electrically connected to the plate electrode 262, thereby atomizing the aerosol source 22.

[0059] Figure 5 It's the smoke bomb containment unit CS. Figure 3 The diagram shows a cross-sectional view along the B-B direction. Figure 5 In the middle, the surface 26s of the lower end 26 of the first smoke cartridge 20 (the end face of the bottom wall portion 13ab side of the first smoke cartridge 20) that abuts against the bottom surface 13as of the smoke cartridge receiving portion CS is shown by dashed lines. Figure 5 This shows a state where the center CP1 (centerline position) of the first smoke cartridge 20 coincides with the center CP2 (centerline position) of the smoke cartridge receiving portion CS. The gap between the inner circumferential surface of the smoke cartridge receiving portion CS and the outer circumferential surface of the first smoke cartridge 20 is minimal, and the configuration is such that, when the first smoke cartridge 20 is received within the smoke cartridge receiving portion CS, ... Figure 5 As shown, center CP1 and center CP2 are roughly the same.

[0060] First, refer to Figure 5The configuration of the first electrode portion located at the lower end 26 of the first cartridge 20 will be described. The plate electrode 261 included in the first electrode portion is a roughly semi-circular shape with straight lines connecting the two ends of an arc, and has a notch 261a in the center of the arc portion. The plate electrode 262 included in the first electrode portion is also a roughly semi-circular shape with straight lines connecting the two ends of an arc, and has a notch 262a in the center of the arc portion. The plate electrodes 261 and 262 are arranged opposite each other across the center CP1 of the first cartridge 20, with their centers overlapping at CP1 on the straight line connecting the notches 261a and 262a. The plate electrodes 261 and 262 are of the same shape and are arranged such that if one of the plate electrodes 261 and 262 is rotated 180 degrees about the center CP1, the other side of the plate electrodes 261 and 262 will coincide. That is, the plate electrodes 261 and 262 are in a point-symmetric relationship about the center CP1.

[0061] The configuration of the second electrode portion located on the bottom wall portion 13ab of the smoke cartridge receiving portion CS will be described. Figure 5 The diagram shows a virtual circle CR1 centered on the center CP2 of the smoke cartridge containment section CS. The diameter of the virtual circle CR1 is larger than the distance D1 between plate electrodes 261 and 262. Furthermore, the diameter of the virtual circle CR1 is smaller than the distance D2 between notches 261a and 262a. Notches 261a and 262a are not mandatory for plate electrodes 261 and 262 and can be omitted. In this case, the diameter of the virtual circle CR1 only needs to be larger than the distance D1 and smaller than the length of the line segment connecting the center CP1 to a point on the arc of the plate electrode 261.

[0062] The protruding electrodes 411, 412, and 413 included in the second electrode section are arranged at equal intervals along the circumference of the virtual circle CR1. Specifically, the angle between the line segment connecting protruding electrode 411 to the center CP2 and the line segment connecting protruding electrode 412 to the center CP2 is 120 degrees; the angle between the line segment connecting protruding electrode 412 to the center CP2 and the line segment connecting protruding electrode 413 to the center CP2 is 120 degrees; and the angle between the line segment connecting protruding electrode 413 to the center CP2 and the line segment connecting protruding electrode 411 to the center CP2 is 120 degrees. Alternatively, the protruding electrodes 411, 412, and 413 included in the second electrode section may not be arranged at equal intervals on the virtual circle CR1. With the first cartridge 20 housed in the cartridge housing CS, the protruding electrodes 411, 412, and 413 can be configured in such a way that, regardless of which position the first cartridge 20 is in, at least one protruding electrode abuts against the plate electrode 261 and at least one protruding electrode abuts against the plate electrode 262.

[0063] As described above, the first smoke cartridge 20 is capable of rotating within the smoke cartridge receiving section CS. That is, the insertion posture of the first smoke cartridge 20 into the smoke cartridge receiving section CS (the circumferential rotational position of the first smoke cartridge 20) is not restricted. Therefore, depending on the method of inserting the first smoke cartridge 20 into the smoke cartridge receiving section CS, such as... Figures 6 to 8 As shown, sometimes the first smoke cartridge is 20 times more than... Figure 5 The state is contained in a clockwise rotation.

[0064] In this embodiment, relative to the first electrode portion (plate electrode 261 and plate electrode 262) provided in the first cartridge 20, the cartridge receiving portion CS is provided with three more protruding electrodes (protruding electrode 411, protruding electrode 412, and protruding electrode 413) than the total number (=2) of plate electrodes contained in the first electrode portion. The protruding electrodes 411, 412, and 413 are arranged at equal intervals on the virtual circle CR1. Therefore, when the first cartridge 20 rotates 360 degrees around the center CP1, one or two of the protruding electrodes 411, 412, and 413 will inevitably contact the plate electrode 261 and plate electrode 262 respectively. That is, with the gap between the plate electrode 261 and plate electrode 262 and a protruding electrode overlapping, as... Figures 5 to 7 As shown, one side of the remaining two protruding electrodes abuts against plate electrode 261, and the other side of the remaining two protruding electrodes abuts against plate electrode 262, thus enabling current to be supplied to load 21. Figure 8 As shown, when the protruding electrodes do not overlap with the gap, two protruding electrodes abut against one side of plate electrode 261 and plate electrode 262, and one protruding electrode abuts against the other side of plate electrode 261 and plate electrode 262, thus enabling power to be supplied to the load 21.

[0065] Thus, the second electrode section provided in the cartridge receiving section CS is configured such that, regardless of the rotational position of the first cartridge 20 in the cartridge receiving section CS, at least one electrode of the second electrode section contacts each electrode of the first electrode section.

[0066] (Second smoke bomb)

[0067] The second smoke cartridge 30 stores the flavor source 31. The second smoke cartridge 30 is detachably housed in the smoke cartridge housing section 17b provided in the interface tube 17.

[0068] The second cartridge 30 imparts flavor to the aerosol generated by the atomization of the aerosol source 22 using the load 21, thereby passing the aerosol through the flavor source 31. The raw material for the flavor source 31 can be shredded tobacco or granulated tobacco. The flavor source 31 can also be composed of plants other than tobacco (e.g., mint, medicinal herbs, vanilla, etc.). Flavorings such as menthol can also be imparted to the flavor source 31.

[0069] The aerosol extractor 1 can generate a scented aerosol through the aerosol source 22, the fragrance source 31, and the load 21. That is, the aerosol source 22 and the fragrance source 31 constitute an aerosol generation source for producing scented aerosols.

[0070] In addition to the independent configuration of aerosol source 22 and fragrance source 31, the configuration of the aerosol generation source used in aerosol extractor 1 can also be a configuration in which fragrance source 31 is omitted and substances that can be contained in fragrance source 31 are added to aerosol source 22, or a configuration in which medicine or the like is added to aerosol source 22 instead of fragrance source 31.

[0071] In this aerosol extractor 1, if a user performs suction, the air intake sensor 15 detects the suction action and sends an aerosol generation request to the MCU 50. Upon receiving the aerosol generation request, the MCU 50 controls the discharge from the power supply 12 to the load 21 to generate aerosol. Through the user's suction, such as... Figure 3 As indicated by arrow A, air flowing in from the air inlet 11i located in the power unit housing 11 flows into the cartridge housing CS through the gap formed between the through hole 13b and the protruding electrodes 411, 412, and 413. This air flows into the interior of the first cartridge 20 through a tiny hole (not shown) formed at the lower end 26 of the first cartridge 20, passing near the load 21. The load 21 atomizes the aerosol source 22 introduced from the reservoir 23 using the wick 24. The aerosol generated by atomization flows through the aerosol flow path 25 along with the air flowing in from the tiny hole, and is supplied to the second cartridge 30 via the connecting path 17c. The aerosol supplied to the second cartridge 30 is flavored by the flavor source 31 and supplied to the inhalation port 32.

[0072] The aerosol extractor 1 is equipped with a notification unit 45 (see reference) that provides various information. Figure 2 The notification unit 45 may be composed of a light-emitting element, a vibrating element, or a sound output element. The notification unit 45 may also be a combination of two or more of the following elements: a light-emitting element, a vibrating element, and a sound output element. The notification unit 45 may be located on any one of the power supply unit 10, the first smoke cartridge 20, and the second smoke cartridge 30, but is preferably located on the power supply unit 10, which is not a consumable item.

[0073] In this embodiment, an OLED (Organic Light Emitting Diode) panel 46 and an oscillator 47 are provided as the notification unit 45. The OLED panel 46 emits light, causing various information related to the aerosol extractor 1 to be notified to the user via the display 16. Additionally, the oscillator 47 vibrates, causing various information related to the aerosol extractor 1 to be notified to the user via the power supply unit housing 11. The notification unit 45 may consist of only one of the OLED panel 46 and the oscillator 47, or it may include other light-emitting elements. Furthermore, the information notified by the OLED panel 46 and the information notified by the oscillator 47 may be different or the same.

[0074] (The structure of electronic circuits formed on a circuit board)

[0075] Figure 9 This is a schematic diagram showing the configuration of the electronic circuit formed on the circuit board 60. The circuit board 60 includes a resistance measuring circuit 52, a resistance measuring circuit 53, a resistance measuring circuit 54, a power-on switching circuit 51, and an MCU 50.

[0076] A resistance measuring circuit 52 is connected to the protruding electrodes 411 and 412, and transmits information corresponding to the resistance value R1 between the protruding electrodes 411 and 412 to the MCU 50. For example, the resistance measuring circuit 52 allows a small current to flow through the protruding electrodes 411 and 412, measures the voltage between them under this condition, and transmits this voltage as information corresponding to the resistance value R1 to the MCU 50. Based on this voltage, the MCU 50 obtains the resistance value R1.

[0077] A resistance measuring circuit 53 is connected to the protruding electrodes 411 and 413, and transmits information corresponding to the resistance value R2 between the protruding electrodes 411 and 413 to the MCU 50. For example, the resistance measuring circuit 53 allows a small current to flow through the protruding electrodes 411 and 413, measures the voltage between them under this condition, and transmits this voltage as information corresponding to the resistance value R2 to the MCU 50. Based on this voltage, the MCU 50 obtains the resistance value R2.

[0078] Resistance measuring circuit 54 is connected to protruding electrodes 412 and 413, and transmits information corresponding to the resistance value R3 between protruding electrodes 412 and 413 to MCU 50. For example, resistance measuring circuit 54 allows a small current to flow through protruding electrodes 412 and 413, measures the voltage between them in this state, and transmits this voltage as information corresponding to the resistance value R3 to MCU 50. MCU 50 obtains the resistance value R3 based on this voltage. Thus, MCU 50 functions as a resistance measuring unit that obtains resistance values ​​R1, R2, and R3 based on information from resistance measuring circuits 52, 53, and 54.

[0079] in the case of Figure 5 In this state, the resistance values ​​R1 and R2 cannot be measured, and the resistance value R3 becomes close to the resistance value of the load 21. If it is Figure 6 In this state, the resistance values ​​R2 and R3 cannot be measured, and the resistance value R1 becomes close to the resistance value of load 21. If it is Figure 7 In this state, the resistance values ​​R1 and R3 cannot be measured, and the resistance value R2 becomes close to the resistance value of load 21. If it is Figure 8 In this state, the resistance value R3 becomes a small value, and the resistance values ​​R1 and R2 become values ​​close to the resistance values ​​of the load 21.

[0080] The power switching circuit 51 includes switches, etc., which switch between states where power supplied from the power source 12 is supplied to the electrode pair of protruding electrodes 411 and 412, states where power is supplied to the electrode pair of protruding electrodes 412 and 413, and states where power is supplied to the electrode pair of protruding electrodes 411 and 413.

[0081] Based on the resistance values ​​R1, R2, and R3, MCU50 determines the electrode pairs to be supplied with power from power source 12 (including at least the power used to atomize aerosol source 22) and controls power switching circuit 51 to supply power to the determined electrode pairs.

[0082] Specifically, the MCU50 selects electrode pairs whose resistance value between electrodes is above a threshold value based on the resistance values ​​R1, R2, and R3. If... Figure 5 In this state, the electrode pair of protruding electrode 412 and protruding electrode 413 is selected. If it is... Figure 6 In this state, the electrode pair of protruding electrode 411 and protruding electrode 412 is selected. If it is... Figure 7 In this state, the electrode pair of protruding electrode 411 and protruding electrode 413 is selected. If it is... Figure 8If the state is such that the electrode pair of protruding electrode 411 and protruding electrode 412 and the electrode pair of protruding electrode 411 and protruding electrode 413 are selected, then either one can be chosen. If there are multiple electrode pairs with resistance values ​​above a threshold, the preferred electrode pair can be predetermined. Alternatively, information on the actual energizing status of each protruding electrode can be accumulated beforehand, and the electrode pair containing the protruding electrode with the fewest energizing cycles can be selected. Alternatively, other thresholds higher than the aforementioned threshold can be preset, and the electrode pair with resistance values ​​below those thresholds can be selected from among the multiple electrode pairs with resistance values ​​above the threshold. Alternatively, a target resistance value can be preset, and the electrode pair with resistance values ​​closest to that target value can be selected.

[0083] (Effects of the implementation method)

[0084] In the aerosol inhaler 1, there is no positioning mechanism in the cartridge housing CS for positioning the circumferential position of the first cartridge 20. Therefore, the first cartridge 20 can be inserted into the cartridge housing CS without knowing its rotational orientation. Consequently, the ease of installation and operation of the first cartridge 20 into the power supply unit 10 is improved.

[0085] Furthermore, in the aerosol inhaler 1, the power supply unit 10 is provided with a second electrode section containing a larger number of electrodes than the first electrode section. Therefore, regardless of the rotational posture of the first cartridge 20, the first cartridge 20 can be electrically connected to the power supply unit 10, and aerosol generation can be performed in the same manner as before.

[0086] Furthermore, in the aerosol extractor 1, the electrode pair that should be energized to generate aerosol is selected based on the resistance value between the protruding electrodes of the second electrode section. For example, even in Figures 5 to 7 In any of the states, it is also possible to select the protruding electrodes that are in contact with plate electrodes 261 and 262 respectively, and to apply current to these protruding electrodes to generate aerosols. Additionally, in Figure 8 In this state, the electrode pair of protruding electrodes 412 and 413 that are in contact with plate electrode 262 is short-circuited, but this electrode pair is not energized. This prevents the supply of the large amount of electricity required for aerosol generation to the short-circuited electrode pair, thus improving safety. As described above, even if the second electrode section contains three electrodes, only two appropriate electrodes are selected for energization. Therefore, even without a positioning mechanism, aerosol generation can be safely performed as before.

[0087] Furthermore, the timing for the MCU50 to acquire the resistance values ​​R1, R2, and R3 is preferably set to the period from the moment the power to the aerosol extractor 1 is switched on via the operation unit 18 to the period during which the initial aerosol generation request is received (in other words, the period during which atomization of the aerosol source 22 is not performed). In this way, the resistance values ​​R1, R2, and R3 can be measured before the large amount of power for aerosol generation is supplied to the first cartridge 20, thus determining the electrode pair to be energized in the second electrode section. Therefore, aerosol generation can be performed safely.

[0088] (First variation of the smoke bomb containment section)

[0089] Figure 10 This is a schematic diagram showing a first modified example of the smoke bomb containment section CS, and it is related to... Figure 5 The corresponding cross-sectional diagram. Figure 10 The only difference in its configuration is the position of the protruding electrode 412 located on the bottom wall 13ab of the smoke cartridge housing CS. Figure 5 They have the same composition.

[0090] Figure 10 A virtual circle CR2 is shown centered on the center CP2 of the smoke cartridge containment section CS. The virtual circle CR2 has a smaller diameter than the virtual circle CR1 and is located inside the virtual circle CR2. The diameter of the virtual circle CR2 is larger than the aforementioned distance D1. A protruding electrode 412 is disposed on this virtual circle CR2.

[0091] exist Figure 10 In the configuration, the angle formed by the line segment connecting the protruding electrode 411 to the center CP2 and the line segment connecting the protruding electrode 412 to the center CP2 is 120 degrees; the angle formed by the line segment connecting the protruding electrode 412 to the center CP2 and the line segment connecting the protruding electrode 413 to the center CP2 is 120 degrees; and the angle formed by the line segment connecting the protruding electrode 413 to the center CP2 and the line segment connecting the protruding electrode 411 to the center CP2 is 120 degrees.

[0092] Even if Figure 10 That kind of composition can also achieve the same Figure 5 The same effect is achieved through the same composition. Furthermore, according to... Figure 10 The structure can also accommodate different types of first smoke cartridges 20 with different structures of the first electrode section.

[0093] For example, imagine a scenario where other types of first cartridges 20 can be housed in cartridge housing CS for use. These other types of first cartridges 20 have a first annular electrode that overlaps with the periphery of the virtual circle CR1 and a second annular electrode that overlaps with the periphery of the virtual circle CR2 as a first electrode portion.

[0094] according to Figure 10Regardless of the rotational posture of the other types of first cartridges 20, the configuration ensures that the protruding electrodes 411 and 413 are in contact with the first annular electrode, and that the protruding electrode 412 is in contact with the second annular electrode. When the protruding electrodes 411 and 413 are in contact with the first annular electrode and the second annular electrode protruding electrode 412, the resistance values ​​between the protruding electrodes 411 and 412 and between the protruding electrodes 412 and 413 are respectively above a threshold value, while the resistance value between the protruding electrodes 411 and 413 is below the threshold value. Therefore, by controlling the supply of electrodes from the power supply 12 to the electrode pair of protruding electrodes 412 and 411, or the electrode pair of protruding electrodes 412 and 413, the MCU 50 can energize the other types of first cartridges 20 to generate aerosol. Thus, according to... Figure 10 The composition enables the aerosol absorber 1 to handle various types of first smoke cartridges 20, thereby increasing the value of the product.

[0095] In addition, Figure 10 In its configuration, by employing a structure in which the protruding electrode 411 and the protruding electrode 413 are symmetrically arranged relative to the center point CP2, it is possible to identify the installation of... Figure 4 Which of the following types of first tobacco cartridges 20 is correct: the type shown or the other types of first tobacco cartridges 20 mentioned above? Specifically, the MCU 50 first obtains a first resistance value between the protruding electrodes 411 and 413. If the first resistance value is above a threshold, it is identified as having a [specific type of cartridge]. Figure 4 The first cartridge 20 is of the type shown. If the first resistance value is less than a threshold, the MCU 50 obtains a second resistance value between protruding electrodes 411 and 412, or between protruding electrodes 413 and 412. If the second resistance value is greater than the threshold, it identifies that another type of first cartridge 20 is installed. If the second resistance value is less than the threshold, the MCU 50 determines that there is a connection error and notifies the user. The MCU 50 can also notify the user of the identified cartridge type. Furthermore, the MCU 50 can change the discharge control to the first cartridge 20 according to the cartridge type. In this way, different types of cartridges can be used to perform optimal control corresponding to the cartridge type, thereby improving the commercial value of the aerosol inhaler 1.

[0096] (Second variation of the smoke bomb containment section)

[0097] Figure 11 This is a schematic diagram showing a second variation of the smoke bomb containment section CS, and it is related to... Figure 5 The corresponding cross-sectional diagram. Figure 11 The only differences in the configuration are the positions of the protruding electrodes 411, 412, and 413 on the bottom wall portion 13ab of the cartridge housing CS, and the additional protruding electrode 414 on the bottom wall portion 13ab. Figure 5 They have the same composition. Figure 11 The virtual circle CR2 shown is Figure 10 The virtual circle CR2 shown is the same.

[0098] exist Figure 11 In its configuration, protruding electrodes 411 and 413 are arranged at equal intervals on the virtual circle CR1, and protruding electrodes 412 and 414 are arranged at equal intervals on the virtual circle CR2. Figure 11 In the configuration, the angle formed by the two line segments connecting each protruding electrode 411, 412 to the center CP2, the angle formed by the two line segments connecting each protruding electrode 412, 413 to the center CP2, the angle formed by the two line segments connecting each protruding electrode 413, 414 to the center CP2, and the angle formed by the two line segments connecting each protruding electrode 414, 411 to the center CP2 are all 90 degrees.

[0099] In Adoption Figure 11 In this configuration, the MCU 50 acquires the resistance values ​​between the electrode pairs of protruding electrodes 411 and 412, 411 and 413, 411 and 414, 412 and 413, 412 and 414, and 413 and 414, respectively. Then, the MCU 50 performs control to select an electrode pair whose acquired resistance value is above a threshold value and supplies power from the power supply 12 to that electrode pair.

[0100] Even if Figure 11 That kind of composition can also achieve the same Figure 5 , Figure 10 The same effect is achieved through the same composition. Additionally, in Figure 11 In its composition, with Figure 5 , Figure 10 Compared to the original configuration, the second electrode section contains a greater number of protruding electrodes. Therefore, it is possible to form multiple electrode pairs with resistance values ​​exceeding a threshold with a high probability. Consequently, it is easier to select electrode pairs to ensure that each protruding electrode is used for energizing without omission, thus improving the durability of the second electrode section. Furthermore, according to... Figure 11 The configuration, with protruding electrodes 411 and 413 symmetrically arranged with respect to the center CP2 point, and protruding electrodes 412 and 414 symmetrically arranged with respect to the center CP2 point, enables identification. Figure 4 The first smoke cartridge 20 of the type shown, together with the other types of first smoke cartridges 20 mentioned above, can increase the value of the product.

[0101] In addition, Figure 11 In the configuration, protruding electrodes 411, 412, 413, and 414 can also be arranged at equal intervals on either virtual circle CR1 or virtual circle CR2.

[0102] (The third variation of the smoke bomb containment section)

[0103] Figure 12 This is a schematic diagram showing a third variation of the smoke bomb containment section CS, and it is related to... Figure 5 The corresponding cross-sectional diagram. Figure 12 The only difference in its configuration is the change in the position of the protruding electrodes 411 and 414. Figure 11 They have the same composition.

[0104] exist Figure 12 In this configuration, protruding electrode 411 is disposed on virtual circle CR2, and protruding electrode 414 is disposed on virtual circle CR1. Figure 12 In the configuration, the angle formed by the two line segments connecting each protruding electrode 411, 412 to the center CP2, the angle formed by the two line segments connecting each protruding electrode 412, 413 to the center CP2, the angle formed by the two line segments connecting each protruding electrode 413, 414 to the center CP2, and the angle formed by the two line segments connecting each protruding electrode 414, 411 to the center CP2 are all 90 degrees.

[0105] Even if Figure 12 That kind of composition can also achieve the same Figure 11 They have the same effect.

[0106] In the above explanation Figure 10 In its configuration, the position of the protruding electrode 412 can also be changed to the center CP2. Additionally, in... Figure 11 , Figure 12 In its configuration, the position of the protruding electrode 412 or protruding electrode 414 can also be changed to the center CP2. As the first cartridge 20, a second or other type is envisioned, having a first electrode portion with a circular electrode arranged at the center CP1 and an annular electrode arranged on the virtual circle CR1. According to... Figure 10 In the configuration, the position of the protruding electrode 412 is changed to the center CP2. Figure 11 , Figure 12 The configuration changes the position of the protruding electrode 412 or protruding electrode 414 to the center CP2. By selecting the electrode pair to be energized based on the resistance value between the electrode pairs, it can cope with... Figure 4 The first cartridge 20 of the type shown is either a second or other type of first cartridge 20. Furthermore, the type can be identified based on the resistance value between the electrode pairs.

[0107] (Fourth variation of the smoke bomb containment section)

[0108] Figure 13 This is a diagram showing the fourth variation of the smoke bomb containment section CS, and it is related to... Figure 3 The corresponding cross-sectional diagram. Figure 13 The configuration is similar to that of the bottom wall portion 13ab, except that it has an annular component 131. Figure 3 They have the same composition.

[0109] Figure 14 yes Figure 13 A schematic cross-sectional view of the B-B direction. Figure 15 It is a schematic representation Figure 13 An exploded perspective view of the bottom wall 13ab of the smoke bomb housing CS.

[0110] like Figure 15 As shown, an annular recess 130, shaped along the outer periphery of the bottom wall portion 13ab, is formed on the bottom surface 13as of the cartridge receiving portion CS. The annular recess 130 surrounds the region where through holes 13b are formed, respectively penetrating the protruding electrodes 411, 412, and 413. An annular member 131 is disposed in the annular recess 130 in a non-fixed state. The non-fixed state refers to a state different from the state in which the annular recess 130 and the annular member 131 are firmly fixed by adhesive, pressing, etc., and refers to a state in which the annular member 131 can be removed from the annular recess 130. The annular member 131 is inserted into the annular recess 130 to the extent that it can rotate within the annular recess 130 if a strong force is applied along its circumference.

[0111] The annular component 131 is a flexible component made of a soft material such as polyurethane, silicone, resin, or rubber. The annular component 131 is composed of a component with a rigidity sufficiently lower than that of the lower end portion 26 of the first cartridge 20. The coefficient of static friction between the surface 26s of the lower end portion 26 of the first cartridge 20 and the annular component 131 is a relatively large value that can suppress the rotation of the first cartridge 20 within the cartridge housing CS.

[0112] like Figure 14 As shown, the annular member 131 is configured such that its inner diameter is smaller than the diameter of the first cartridge 20, allowing it to contact the surface 26s of the first cartridge 20 throughout its circumference. Furthermore, the vertical height of the annular member 131 is preferably greater than the vertical depth of the annular recess 130. More preferably, the upper surface of the annular member 131 is located between the front ends of the protruding electrodes 411, 412, and 413 and the bottom surface 13as of the cartridge receiving portion CS.

[0113] As mentioned above, in Figure 14 as well as Figure 15In the cartridge receiving portion CS shown, the annular member 131 is embedded in the bottom wall portion 13ab, protruding within the cartridge receiving portion CS. Therefore, when the first cartridge 20 is received in the cartridge receiving portion CS, even if a circumferential rotational force is applied to the first cartridge 20, the rotation of the first cartridge 20 caused by this force will be suppressed by the frictional force between the annular member 131 and the first cartridge 20. This suppression of the rotation of the first cartridge 20 prevents wear on the first cartridge 20 and the cartridge receiving portion CS caused by friction.

[0114] Furthermore, by suppressing the rotation of the first smoke cartridge 20, short circuits can be prevented, thus improving safety. For example, in Figure 8 In the indicated state, for example, the first cartridge 20 is energized using the protruding electrodes 411 and 412. If the first cartridge 20 rotates during this energization process and the protruding electrode 412 comes into contact with the plate electrode 261, a short circuit occurs. By suppressing the rotation of the first cartridge 20, this short circuit can be prevented.

[0115] In addition, Figure 14 as well as Figure 15 In the shown cartridge housing CS, the annular member 131 is disposed in a non-fixed state on the bottom wall portion 13ab of the cartridge housing CS. Therefore, a gap is formed between the annular member 131 and the bottom wall portion 13ab of the cartridge housing CS. The capillary force generated by this gap can trap the aerosol source 22 leaking from the first cartridge 20. As a result, the aerosol source 22 can be prevented from intruding into the areas where the protruding electrodes and plate electrodes are disposed, thus improving durability and safety.

[0116] exist Figure 14 as well as Figure 15 In this configuration, the annular member 131 has the function of suppressing the rotation of the first cartridge 20. However, any configuration that can generate friction between the bottom wall portion 13ab and the first cartridge 20 is acceptable. For example, it is also possible to replace the annular member 131 with a plurality of arc-shaped flexible members disposed in the annular recess 130.

[0117] (Preferred configuration of the smoke bomb containment in the fourth variation)

[0118] The following is about Figure 14 as well as Figure 15 The preferred embodiment of the smoke cartridge housing CS shown will be described. The preferred embodiments shown below can be combined appropriately.

[0119] The surface of the first cartridge 20 side of the annular component 131 (upper surface 131sa (reference)) Figure 15Part or all of the annular component 131 is preferably an uneven surface. This configuration can further increase the static friction coefficient between the annular component 131 and the first cartridge 20, thereby enhancing the rotation suppression effect of the first cartridge 20.

[0120] The bottom wall portion 13ab side surface of the annular component 131 (see reference) Figure 15 Part or all of the annular component 131 is preferably an uneven surface. This configuration increases the coefficient of static friction between the bottom surface 130b of the annular recess 130 and the annular part 131, preventing the annular component 131 from rotating. In addition, the unevenness of the lower surface 131sb of the annular component 131 can enhance capillary force and improve the collection effect of the aerosol source 22.

[0121] Part or all of the bottom surface 130b of the annular recess 130 is preferably a concave-convex surface. This configuration increases the coefficient of static friction between the annular member 131 and the bottom surface 130b, preventing the annular member 131 from rotating. Furthermore, the concavity and convexity of the bottom surface 130b enhances capillary force, thereby improving the aerosol source 22's collection effect.

[0122] Figure 16 It means Figure 14 A cross-sectional schematic diagram of a modified example of the C-C view. In this modified example, at least one recess 131b is formed on the lower surface 131sb of the annular member 131, and a protrusion 130c is formed on the bottom surface 130b of the annular recess 130 that engages with each recess 131b of the annular member 131. Figure 14 as well as Figure 15 The smoke cartridge receiving part CS is different. The recess 131b and the protrusion 130c that engages with it are, for example, cylindrical or cubic in shape.

[0123] according to Figure 16 In this configuration, the annular member 131 and the bottom wall portion 13ab of the cartridge receiving portion CS are engaged by a recess 131b and a protrusion 130c. Therefore, rotation of the annular member 131 can be suppressed. Alternatively, by forming a protrusion on the lower surface 131sb of the annular member 131 and forming a recess on the bottom surface 130b of the annular recess 130 that engages with the protrusion, the same effect can be achieved. To improve the engaging force, it is preferable that multiple pairs of recesses 131b and protrusions 130c are arranged circumferentially.

[0124] Figure 17 It means Figure 14A cross-sectional schematic diagram of another modified example of the C-C view. In this modified example, at least one recess 131a is formed on the outer peripheral side surface 131sc of the annular member 131, and a protrusion 130a is formed on the wall surface 130s of the annular recess 130 opposite to the outer peripheral side surface 131sc, which engages with each recess 131a of the annular member 131. Figure 14 as well as Figure 15 The smoke cartridge receiving part CS is different. The concave part 131a and the convex part 130a that engages with it are, for example, cylindrical, cuboid, annular, etc.

[0125] according to Figure 17 The annular component 131 is configured such that it engages with the wall surface 130s of the smoke cartridge receiving portion CS via a recess 131a and a protrusion 130a. Therefore, movement of the annular component 131 in the vertical direction can be restricted. Consequently, the annular component 131 is prevented from floating due to the aerosol source 22 trapped between the annular component 131 and the bottom surface 130b of the annular recess 130.

[0126] Alternatively, by forming a protrusion on the outer peripheral side 131sc of the annular member 131, and having the wall surface 130s of the annular recess 130 engage with the protrusion, the same effect can be achieved. To effectively prevent the annular member 131 from lifting, it is preferable that the recess 131a and the protrusion 130a are each formed into annular shapes along the circumferential direction.

[0127] Alternatively, the annular member 131 can be configured such that a protrusion or a recess is formed on the inner peripheral side surface 131sd of the annular member 131, and a recess or protrusion that engages with the protrusion or recess is provided on the wall surface of the annular recess 130 opposite to the inner peripheral side surface 131sd. In this configuration, the annular member 131 can also be prevented from floating up.

[0128] In the aerosol inhaler 1 described above and its variations, two electrodes (plate electrodes 261, 262) are provided in the first cartridge 20. However, the number of electrodes provided in the first cartridge 20 is not limited to two.

[0129] For example, a heater for heating the flavor source 31 can be added to the first cartridge 20, and a total of four electrodes, namely two electrodes for energizing the heater and two electrodes for energizing the load 21, can be provided in the first cartridge 20. Alternatively, two heaters for heating the aerosol source 22 can be provided in the first cartridge 20, and a total of four electrodes for energizing the two heaters respectively can be provided in the first cartridge 20.

[0130] In these configurations, it is sufficient to have at least five protruding electrodes provided in the cartridge housing CS, which is more than four. In this way, regardless of the rotational position of the first cartridge 20, the electrodes included in the second electrode section can contact each electrode included in the first electrode section to energize the two heaters of the first cartridge 20 respectively.

[0131] In the aerosol inhaler 1, it is preferable that at least a portion of the area on the surface 26s of the lower end 26 of the first cartridge 20 that can contact the annular member 131 is an uneven surface. This can improve the rotation suppression effect and capillary force of the annular member 131.

[0132] In the above description, the upper opening of the smoke cartridge receiving section CS is blocked by the second smoke cartridge 30. However, it could also be configured, for example, to... Figure 1 The power unit housing 11 of the aerosol inhaler 1 has a second cartridge 30 mounted on its upper end face and a first cartridge 20 mounted on its lower end face. In this case, the following configuration can be adopted: after inserting the first cartridge 20 into the cartridge holder 14, for example, the cover provided on the lower end face of the power unit housing 11 is closed, thereby sealing the lower end opening of the cartridge holder 14. In this configuration, for example, a second electrode portion is provided on the cover portion, and the first electrode portion and the second electrode portion are electrically connected when the cover portion is closed. In this configuration, the cartridge holder 14 and the cover portion constitute a receiving portion for accommodating the first cartridge 20.

[0133] (Preferred configuration of electronic circuits formed on a circuit board)

[0134] Figure 18 This is a schematic diagram illustrating a preferred configuration example of an electronic circuit formed on a circuit board 60. Figure 18 In the example shown, the circuit board 60 includes: a switch group consisting of six switches SW1 to SW6, which are composed of transistors, etc.; a resistor element 61 and a resistor element 62, which are composed of transistors or resistors and have fixed resistance values; protruding electrodes 411 to 413; and an MCU 50 (not shown). The resistance value of resistor element 61 is set to Ra, and the resistance value of resistor element 62 is set to Rb.

[0135] One end of each of switches SW1 to SW4 is connected to the supply line of the power supply voltage Vdd supplied from power supply 12. The other end of switch SW1 is connected to the protruding electrode 411 via resistor element 61. The other end of switch SW2 is also connected to the protruding electrode 411. That is, the first parallel circuit, formed by the series connection of resistor element 61 and switch SW1 and the parallel connection of switch SW2, is connected between power supply 12 and protruding electrode 411.

[0136] The other end of switch SW4 is connected to the protruding electrode 412 via resistor 62. The other end of switch SW3 is also connected to the protruding electrode 412. That is, the second parallel circuit, formed by the series connection of resistor 62 and switch SW4 and the parallel connection of switch SW3, is connected between power supply 12 and protruding electrode 412.

[0137] One end of each of switches SW5 and SW6 is grounded. The other end of switch SW5 is connected to the protruding electrode 413. The other end of switch SW6 is connected to the protruding electrode 412.

[0138] Switches SW1 through SW6 are controlled by MCU50 for opening and closing. The protruding electrode 411 is connected to a voltage measuring circuit (not shown), for example, built into MCU50, which measures the voltage V1 of the protruding electrode 411. The protruding electrode 412 is connected to a voltage measuring circuit (not shown), for example, built into MCU50, which measures the voltage V2 of the protruding electrode 412. The voltage measuring circuits for measuring voltage V1 and V2 can be configured separately or can share a single voltage measuring circuit.

[0139] (Method for determining the resistance value R1 between protruding electrode 411 and protruding electrode 412)

[0140] The MCU50 controls the circuit to close switches SW1 and SW6, and open all other switches. In this state, the MCU50 measures the voltage V1 of the protruding electrode 411 through the voltage measuring circuit. The voltage V1 is expressed using the resistance value R1, the resistance value Ra, and the power supply voltage Vdd by the following equation (1).

[0141] V1=Vdd*{R1 / (Ra+R1)}··(1)

[0142] If equation (1) is solved for R1, then equation (2) can be obtained. Therefore, by obtaining voltage V1, MCU50 can measure the resistance value R1 between protruding electrode 411 and protruding electrode 412.

[0143] R1=Ra / {(Vdd / V1)-1}··(2)

[0144] (Method for measuring the resistance value R2 between protruding electrode 411 and protruding electrode 413)

[0145] The MCU50 controls the circuit to close switches SW1 and SW5 out of switches SW1 to SW6, and open all other switches. In this state, the MCU50 measures the voltage V1 of the protruding electrode 411 through the voltage measuring circuit. The voltage V1 is expressed using the resistance value R2, the resistance value Ra, and the power supply voltage Vdd by the following equation (3).

[0146] V1=Vdd*{R2 / (Ra+R2)}··(3)

[0147] If equation (3) is solved for R2, then equation (4) can be obtained. Therefore, by obtaining voltage V1, MCU50 can measure the resistance value R2 between protruding electrode 411 and protruding electrode 413.

[0148] R2=Ra / {(Vdd / V1)-1}··(4)

[0149] (Method for determining the resistance value R3 between protruding electrode 412 and protruding electrode 413)

[0150] The MCU50 controls the circuit to close switches SW4 and SW5 out of switches SW1 to SW6, and open all other switches. In this state, the MCU50 measures the voltage V2 of the protruding electrode 412 through the voltage measuring circuit. The voltage V2 is represented by the following equation (5) using the resistance value R3, the resistance value Rb, and the power supply voltage Vdd.

[0151] V2=Vdd*{R3 / (Rb+R3)}··(5)

[0152] If equation (5) is solved for R3, then equation (6) can be obtained. Therefore, by obtaining voltage V2, MCU50 can measure the resistance value R3 between protruding electrode 412 and protruding electrode 413.

[0153] R3=Rb / {(Vdd / V2)-1}··(6)

[0154] The operation that enables power to be supplied from the power unit 10 to the first smoke cartridge 20 is as follows.

[0155] First, the MCU 50 obtains the resistance value R1 using the method described above. If the difference between the obtained resistance value R1 and the resistance value of the load 21 is below a predetermined threshold, the MCU 50 determines that the load 21 is connected to the protruding electrodes 411 and 412. Then, the MCU 50 controls the circuit to close switches SW2 and SW6 (out of SW1 to SW6) and open all other switches. This allows power to be supplied to the first cartridge 20 via the protruding electrodes 411 and 412.

[0156] If the difference between the obtained resistance value R1 and the resistance value of the load 21 exceeds the aforementioned threshold, the MCU 50 then obtains the resistance value R2 using the aforementioned method. If the difference between the obtained resistance value R2 and the resistance value of the load 21 is below the aforementioned threshold, the MCU 50 determines that the load 21 is connected to the protruding electrode 411 and protruding electrode 413. Then, the MCU 50 controls the circuit to close switches SW2 and SW5 (out of switches SW1 to SW6) and open all other switches. This allows power to be supplied to the first cartridge 20 via the protruding electrode 411 and protruding electrode 413.

[0157] If the difference between the obtained resistance value R2 and the resistance value of the load 21 exceeds the aforementioned threshold, the MCU 50 then obtains the resistance value R3 using the aforementioned method. If the difference between the obtained resistance value R3 and the resistance value of the load 21 is below the aforementioned threshold, the MCU 50 determines that the load 21 is connected to the protruding electrode 412 and the protruding electrode 413. Then, the MCU 50 controls the switch SW3 and switch SW5 out of switches SW1 to SW6 to be closed, and all other switches are open. As a result, power is supplied to the first cartridge 20 via the protruding electrode 412 and the protruding electrode 413.

[0158] If the difference between the obtained resistance value R3 and the resistance value of the load 21 exceeds the aforementioned threshold, the MCU50 determines that power cannot be supplied to the first cartridge 20 or that the first cartridge 20 has not been inserted, and issues an error notification. Furthermore, the order in which the resistance values ​​are obtained is not limited to the above. For example, they can be obtained in the order of resistance values ​​R2, R1, R3, or in the order of resistance values ​​R3, R2, R1.

[0159] Thus, according to Figure 18 The circuit configuration shown allows for the sequential acquisition of resistance values ​​R1, R2, and R3, or for energizing only the desired pair of protruding electrodes, simply by changing the closed switch among switches SW1 to SW6.

[0160] In addition, Figure 18In this configuration, the circuit including switches SW1 to SW4 and resistors 61 and 62 is connected between the power supply 12 and the protruding electrodes 411 and 412, and the circuit including switches SW5 and SW6 is connected between ground and the protruding electrodes 412 and 413, but is not limited to this. Alternatively, the circuit including switches SW1 to SW4 and resistors 61 and 62 can be connected between ground and the protruding electrodes 411 and 412, and the circuit including switches SW5 and SW6 can be connected between the power supply 12 and the protruding electrodes 412 and 413. In other words, in Figure 18 Alternatively, the power supply line Vdd can be changed to a ground line connected to ground, and the ground can be changed to the aforementioned supply line.

[0161] This specification describes at least the following items. Additionally, elements corresponding to the above embodiments are indicated in parentheses, but the scope is not limited thereto. (1)

[0163] A power supply unit (power supply unit 10) of an aerosol generating device (aerosol extractor 1) includes a receiving section (cartridge receiving section CS) for receiving a cylindrical cartridge (first cartridge 20) that stores an aerosol source (aerosol source 22).

[0164] A first electrode portion comprising multiple electrodes (plate electrodes 261, 262) is provided on the end face (surface 26s) of the aforementioned tobacco cartridge.

[0165] The aforementioned receiving portion has a second electrode portion in the region opposite to the aforementioned end face.

[0166] The second electrode portion includes more electrodes (protruding electrodes 411, 412, 413) than the total number of electrodes included in the first electrode portion, and these electrodes are capable of contacting each of the electrodes included in the first electrode portion.

[0167] According to (1), regardless of the cartridge's storage state, the electrodes in the second electrode section can contact each electrode in the first electrode section to energize the cartridge. With this configuration, there is no need to provide a cartridge positioning mechanism in the storage section, improving the operability of cartridge installation. Furthermore, by energizing only one electrode in the second electrode section that contacts each electrode in the first electrode section, energization in a short-circuit state can be prevented. Additionally, even with cartridges of different configurations housing the first electrode section, electrical connection with various types of cartridges is possible, increasing the commercial value of the aerosol inhaler. (2)

[0169] According to the power supply unit of the aerosol generating device described in (1),

[0170] The second electrode portion is configured such that, regardless of the rotational position of the cartridge in the receiving portion, at least one electrode of the second electrode portion is in contact with each electrode of the first electrode portion.

[0171] According to (2), regardless of the storage state of the cartridge, the electrodes contained in the second electrode section can contact the electrodes contained in the first electrode section to energize the cartridge. (3)

[0173] The power supply unit of the aerosol generating apparatus described in (2) includes:

[0174] The resistance measuring unit (MCU50) measures the resistance values ​​(resistance values ​​R1, R2, R3) between all electrode pairs selectable from all electrodes included in the second electrode unit described above; and

[0175] The control unit (MCU50) selects the same number of electrodes as the electrodes in the first electrode section from the electrodes included in the second electrode section based on the resistance value measured by the resistance measuring unit, and controls the energization of the selected electrodes.

[0176] According to (3), it is possible to energize only the electrodes in the second electrode section that are electrically connected to each electrode in the first electrode section. Therefore, it is possible to prevent energization in a short-circuit state. (4)

[0178] According to the power supply unit of the aerosol generating device described in (3),

[0179] The control unit selects the electrode pair whose resistance value is above the threshold.

[0180] According to (4), it is possible to energize the electrode pairs that are not short-circuited. (5)

[0182] According to the power supply unit of the aerosol generating device described in (3) or (4),

[0183] The resistance measuring unit measures the resistance value of the electrode pair during the period when the aerosol source is not atomized.

[0184] According to (5), the resistance value can be measured before supplying a large amount of electricity for aerosol generation to the cartridge, thus determining the electrode to be energized in the second electrode section. Therefore, aerosol generation can be carried out safely. (6)

[0186] According to the power supply unit of the aerosol generating device described in (2),

[0187] The second electrode portion is composed of a first electrode (protruding electrode 411), a second electrode (protruding electrode 412), and a third electrode (protruding electrode 413).

[0188] The power supply unit includes:

[0189] A first parallel circuit is connected between the power supply (power supply 12) and ground, and the first electrode; and

[0190] A second parallel circuit is connected between the power supply and the ground, and the second electrode.

[0191] The first parallel circuit is composed of a series circuit of a resistive element (resistive element 61) and a first switch (switch SW1) and a second switch (switch SW2) connected in parallel.

[0192] The second parallel circuit is composed of a series circuit of a resistive element (resistive element 62) and a fourth switch (switch SW4) and a parallel connection of a third switch (switch SW3).

[0193] The power supply unit also includes:

[0194] The fifth switch (switch SW5) is connected between the power source and the other side of the ground and the third electrode;

[0195] The sixth switch (switch SW6) is connected between the power source and the other side of the ground and the second electrode;

[0196] A voltage measuring circuit measures the voltage at the first electrode (voltage V1) and the voltage at the second electrode (voltage V2); and

[0197] The controller (MCU50) controls the opening and closing of the switch group including the first switch, the second switch, the third switch, the fourth switch, the fifth switch and the sixth switch, and obtains the resistance values ​​between all electrode pairs that can be selected from all electrodes contained in the second electrode section based on the voltage measured by the voltage measuring circuit.

[0198] According to (6), the electrodes in the second electrode section that are electrically connected to each electrode in the first electrode section can be identified by their resistance values, and energization can be applied only to those electrodes. Therefore, energization in a short-circuit state can be prevented. In addition, this effect can be achieved with a simple circuit configuration. (7)

[0200] According to the power supply unit of the aerosol generating device described in (6),

[0201] The controller performs the following processing in a time-sharing manner:

[0202] Based on the voltage of the first electrode measured by the voltage measuring circuit when only the first switch and the sixth switch are closed, a first resistance value (resistance value R1) between the first electrode and the second electrode is obtained.

[0203] Based on the voltage of the first electrode measured by the voltage measuring circuit with only the first switch and the fifth switch closed, a second resistance value (resistance value R2) between the first electrode and the third electrode is obtained; and

[0204] Based on the voltage of the second electrode measured by the voltage measuring circuit with only the fourth and fifth switches closed, a third resistance value (resistance value R3) between the second electrode and the third electrode is obtained.

[0205] When the first resistance value meets a specified condition, the switch group is controlled to open and close so that only the first electrode and the second electrode are energized.

[0206] When the second resistance value meets the specified condition, the switch group is controlled to open and close so that only the first electrode and the third electrode are energized.

[0207] When the third resistance value meets the specified conditions, the switch group is controlled to open and close so that only the second electrode and the third electrode are energized.

[0208] According to (7), only the electrodes in the second electrode section that are electrically connected to each electrode in the first electrode section can be energized. Therefore, energization in a short-circuit state can be prevented. In addition, this effect can be achieved with a simple circuit configuration. (8)

[0210] According to any one of (1) to (5), the power supply unit of the aerosol generating device

[0211] The aforementioned first electrode section consists of two first secondary electrodes (plate electrodes 261, 262) arranged opposite each other across the center (center CP1) of the aforementioned tobacco cartridge.

[0212] The second electrode section is composed of three or more second sub-electrodes (protruding electrodes 411, 412, 413) arranged at equal intervals on a circle (virtual circle CR1) centered on the center (center CP2) of the aforementioned receiving section.

[0213] According to (8), regardless of the rotational position within the cartridge housing, the electrodes contained in the second electrode section can contact the electrodes contained in the first electrode section to energize the cartridge. (9)

[0215] According to any one of (1) to (5), the power supply unit of the aerosol generating device

[0216] The aforementioned first electrode section consists of two first secondary electrodes (plate electrodes 261, 262) arranged opposite each other across the center (center CP1) of the aforementioned tobacco cartridge.

[0218] According to (9), regardless of the rotational position within the cartridge housing, the electrodes in the second electrode section can contact the electrodes in the first electrode section to energize the cartridge. Furthermore, for example, if a cartridge having a first annular electrode and a second annular electrode disposed inside the first annular electrode can be housed within the housing as the first electrode section, then the first annular electrode and the second annular electrode can each necessarily contact a second auxiliary electrode. Therefore, even when multiple different types of cartridges are installed, it is safe to energize each type of cartridge. (10)

[0220] According to the power supply unit of the aerosol generating device described in (9),

[0221] The angles formed by the two line segments of each of the two adjacent second secondary electrodes in the circumferential direction of the circle connected to the second electrode portion are equal with respect to the center of the circle.
