The present invention relates to a non-burning type flavor inhaler having a shape extending from a non-inhalation end toward an inhalation end along a predetermined direction.
A non-burning type flavor inhaler for inhaling flavor without burning has been known. The non-burning type flavor inhaler has a shape extending from a non-inhalation end toward an inhalation end along a predetermined direction. The non-burning type flavor inhaler comprises an aerosol source for generating an aerosol, a heat source for heating the aerosol source without burning, and a power source for supplying power to the heat source.
There has been proposed a non-burning type flavor inhaler, which realizes a feeling similar to a general cigarette by lighting an LED in a state (puff state) that a user is inhaling an aerosol, the general cigarette generating an aerosol along with burning (for example, Patent Literature 1). A non-burning type flavor inhaler, which notifies a user of remaining battery power, heat source temperatures, aerosol characteristics and the like according to a lighting mode of LED, has also proposed (for example, Patent Literature 2). A technique, which uses an LED lighting mode different from that in a puff state as an LED lighting mode in a non-puff state, has been proposed (for example, Patent Literature 3).
In a general cigarette generating an aerosol along with burning, a total length of a cigarette becomes shorter along with an increase in the number of puffs, and thus a user can easily grasp a progress status of a puff.
However, in the above non-burning type flavor inhaler, a total length of a non-burning type flavor inhaler does not change even when the number of puffs increases, and thus it is difficult for a user to grasp a progress status of a puff.

Hereinafter, embodiments of the present invention will be described. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. It is noted that the drawings are schematic, and the ratios of dimensions and the like are different from the actual ones.
Therefore, specific dimensions and the like should be determined by referring to the following description. Of course, the drawings include the parts with different dimensions and ratios.
A non-burning type flavor inhaler according to an embodiment has a shape extending from a non-inhalation end toward an inhalation end along a predetermined direction. The non-burning type flavor inhaler comprises an aerosol source that generates an aerosol, an atomizer that atomizes the aerosol source without burning, a power source that supplies power to the atomizer, a light-emitting element, and a control unit that controls the light-emitting element. The control unit controls the light-emitting element in a first light-emitting mode in a puff state inhaling the aerosol, and controls the light-emitting element in a second light-emitting mode different from the first light-emitting mode in a non-puff state not inhaling the aerosol. The second light-emitting mode changes according to a number of puff actions for inhaling the aerosol.
First, in the embodiment, a control unit controls a light-emitting element in a second light-emitting mode different from a first light-emitting mode in a non-puff state not inhaling an aerosol. Thus, even in a non-puff state, a user can grasp whether or not a non-burning type flavor inhaler is in a usable state. Further, as a light-emitting mode in a puff state is different from a light-emitting state in a non-puff state, it is possible to realize a feeling similar to a general cigarette that generates an aerosol along with burning.
Second, in the embodiment, a second light-emitting mode changes according the number of puff actions of inhaling an aerosol. Thus, a user can easily grasp a progress status of a puff by the change in the second light-emitting mode, in a non-puff state easy to visually recognize lighting of a light-emitting element.
Hereinafter, a non-burning type flavor inhaler according to a first embodiment will be explained.
In the first embodiment, the non-burning type flavor inhaler 100 is a device for inhaling flavor without burning, and has a shape extending along a predetermined direction A that is a direction from a non-inhalation end toward an inhalation end.
As showed in
The electrical unit 110 comprises a power source 10, a sensor 20, a pushbutton 30, a light-emitting element 40 and a control circuit 50.
The power source 10 is a lithium-ion battery, for example. The power source 10 supplies power required for operating the non-burning type flavor inhaler 100. For example, the power source 10 supplies power to the sensor 20, the light-emitting element 40 and the control circuit 50. Further, the power source 10 applies power to a heat source 80 described later.
The sensor 20 detects a wind pressure generated by a user's inhaling action. Specifically, the sensor 20 detects a negative pressure when the air is inhaled toward the atomizing unit 120. The sensor 20 is not particularly limited, but may be composed of a piezoelectric element.
The pushbutton 30 is configured to be pressed into the inhalation end side along the predetermined direction A. For example, by a predetermined action of the pushbutton 30 (i.e. an action for continuously pressing the pushbutton 30 over a predetermined number of times), the power of the non-burning type flavor inhaler 100 is turned on. When the power of the non-burning type flavor inhaler 100 is turned on, the power is supplied to the control circuit 50 from the power source 10 and the power is supplied to the sensor 20 and light-emitting element 40 from the power source 10 via the control circuit 50. Note that the power supply to the heater 80 is performed when the power is turned on and also the user's inhaling action is detected by the sensor 20. That is, the power supply to the heater 80 is not performed in a non-inhalation state that the aerosol is not inhaled.
Moreover, by a predetermined action of the pushbutton 30 (i.e. an action for long press of the pushbutton 30), the power of the non-burning type flavor inhaler 100 may be turned off. Since the power of the non-burning type flavor inhaler 100 is turned off by the predetermined action of the pushbutton 30, consumption power can be decreased when the non-burning type flavor inhaler 100 is not used.
The push button 30 may be a configuration for performing at least one of turning on or turning off the power of the non-burning type flavor inhaler 100.
The light-emitting element 40 is a light source such as an LED and an electric lamp. The light-emitting element 40 is provided on a sidewall extending along a predetermined direction. The light-emitting element 40 is preferably provided in the vicinity of the non-inhalation end. Thus, compared with a case where a light-emitting element is provided in the vicinity of the non-inhalation end on an axial line in the predetermined direction A, a user can easily recognize a light-emitting pattern of the light-emitting element 40 during an inhalation action. A light-emitting pattern of the light-emitting element 40 is a pattern to notify a user of a state of the non-burning type flavor inhaler 100.
The control circuit 50 controls the operation of the non-burning type flavor inhaler 100. In particular, the control circuit 50 controls a light-emitting pattern of the light-emitting element 40, and controls power amount supplied to a heat source 80.
The atomizing unit 120 comprises, as showed in
The holder 60 has a cylindrical shape, and holds the aerosol source for generating aerosol. The aerosol source is liquid such as propylene glycol and glycerin. The holder 60 is composed of a porous body impregnated with an aerosol source, for example. The porous body is a resin web, for example.
Further, in the first embodiment, the ceramic 123 is arranged inside the holder 60, suppressing volatilization of the aerosol source held by the holder 60.
The absorber 70 is provided adjacent to the holder 60, and is composed of a substance to absorb the aerosol source from the holder 60. The absorber 70 is made of glass fiber, for example.
The heat source 80 heats the aerosol source without burning. For example, the heat source 80 is a heating wire wound around the absorber 70. The heat source 80 heats the aerosol source absorbed by the absorber 70.
The breaker 90 is a member for breaking a part of predetermined film 133 in the state that the capsule unit 130 is mounted. In the embodiment, the breaker 90 is held by a partition member 126 for partitioning the atomizing unit 120 and the capsule unit 130. The partition member 126 is made of Polyacetal resin. The breaker 90 is a hollow cylindrical needle extending along a predetermined direction A, for example. By piercing a tip of the hollow needle into a predetermined film 133, a part of the predetermined film 133 is broken. Further, an inner space of the hollow needle forms an airflow path that communicates pneumatically the atomizing unit 120 with the capsule unit 130. It is preferable that a mesh having a roughness of not passing a material composing the flavor source 131 is provided inside the hollow needle. The roughness of the mesh is 80 meshes or more and 200 meshes or less, for example.
In such a case, the insertion depth of the hollow needle into the capsule unit 130 is preferably 1.0 mm or more and 5.0 mm or less, more preferably, 2.0 mm or more and 3.0 mm or less. At this insertion depth, the parts except a desired portion are not broken, suppressing detachment of the flavor source 131 filled in the space which is partitioned by the predetermined film 133 and the filter 132. Furthermore, since the detachment of the hollow needle from the space is suppressed, a proper airflow path to the filter 132 from the hollow needle can be preferably maintained.
In a vertical section with respect to the predetermined direction A, a sectional area of a vertical needle is preferably 2.0 mm2 or more and 3.0 mm2 or less. Thus, the flavor source 131 is prevented from falling off the capsule unit 130 when the hollow needle is removed.
The tip of the hollow needle preferable has an inclination of 30° or more and 45° or less with respect to the vertical direction to the predetermined direction A.
However, the embodiment is not limited to this. The breaker 90 may be a part adjacent to the predetermined film 133 in a state that the capsule unit 130 is mounted. A part of the predetermined film 133 may be broken by a pressure applied to such a part by a user.
The capsule unit 130 is configured to be attachable/detachable to/from the main body unit. The capsule unit 130 comprises a flavor source 131, a filter 132, and a predetermined film 133. The flavor source 131 is filled in a space partitioned by the predetermined film 133 and the filter 132. The main body unit is a unit that is composed of parts other except the capsule unit 130. For example, the main body unit includes the electrical unit 110, the holder 60, the absorber 70 and the heat source 80.
The flavor source 131 is provided on the inhalation end side than the holder 60 holding the aerosol source, and generates flavor inhaled by a user together with aerosol generated by the aerosol source. It is noted that the flavor source 131 is composed of a solid substance so as not to flow out of the space partitioned by the predetermined film 133 and the filter 132. As a flavor source 131, it is possible to use shredded tobacco, a molded body of granulated tobacco material, and a molded body formed into a sheet tobacco material. The flavor source 131 may be composed of a plant other than tobacco (for example, mint, herbs, and the like). The flavor source 131 may be given flavors such as menthol.
When the flavor source 131 is composed of tobacco material, as the tobacco material is apart from the heat source 80, it is possible to inhale the flavor without heating the tobacco material. In other words, it is noted that inhalation of unwanted substance generated by heating the tobacco material is suppressed.
In the first embodiment, the amount of the flavor source 131 filled in the space partitioned by the filter 132 and the predetermined film 133 is preferably 0.15 g/cc or more and 1.00 g/cc or less. The volume occupancy of the flavor source 131 in the space partitioned by the filter 132 and the predetermined film 133 is preferably 50% or more and 100% or less. The volume of the space partitioned by the filter 132 and the predetermined film 133 is preferably 0.6 ml or more and 1.5 ml or less. In such conditions, the flavor source 131 can be contained to the extent enough to enable a user to taste flavor while maintaining an appropriate size of the capsule unit 130.
In the state where a part of the predetermined film 133 is broken by the breaker 90 and where the atomizing unit 120 communicates with the capsule unit 130, when air is inhaled from a tip portion (non-broken portion) of the capsule unit 130 to a distal end of the filter 132 at a flow rate of 1050 cc/min, an airflow resistance (pressure loss) of the capsule unit 130 is preferably 10 mmAq or more and 100 mmAq or less, as a whole, more preferably, 20 mmAq or more and 90 mmAq or less. By setting the airflow resistance of the flavor source 131 to the above preferable range, aerosol is prevented from being overly filtered by the flavor source 131, and thus flavor can be efficiently supplied to a user. Incidentally, 1 mmAq corresponds to 9.80665 Pa, and the airflow resistance can be expressed by Pa.
The filter 132 is adjacent to the inhalation end side with respect to the flavor source 131, and is composed of a permeable substance. The filter 132 is preferably an acetate filter, for example. The filter 132 preferably has roughness of a degree not to pass through a material constituting the flavor source 131.
An airflow resistance of the filter 132 is preferably 5 mmAq or more and 20 mmAq or less. Accordingly, it is possible to efficiently pass through aerosol while efficiently absorbing a vapor component generated by the flavor source 131, and thus proper flavor can be supplied to a user. Further, it is possible to give a user an appropriate feeling of air resistance.
A ratio (mass ratio) between the mass of the flavor source 131 and the mass of the filter 132 is preferably in a range of 3:1 to 20:1, more preferably, in a range of 4:1 to 6:1.
The predetermined film 133 is formed integrally with the filter 132, and is composed of impermeable material. The predetermined film 133 covers a part of the outer surface of the flavor source 131 except a portion adjacent to the filter 132. The predetermined film 133 includes at least one compound selected from a group consisting of gelatin, polypropylene and polyethylene terephthalate. Gelatin, polypropylene, polyethylene and polyethylene terephthalate are not permeable, and suitable for forming a thin film. Gelatin, polypropylene, polyethylene and polyethylene terephthalate provide a sufficient resistance to moisture contained in the flavor source 131. Polypropylene, polyethylene and polyethylene terephthalate are especially excellent in a water resistance. Further, gelatin, polypropylene and polyethylene have a base resistance, and are thus hardly degraded by a basic component, even when the flavor source 131 has a basic component.
A thickness of the predetermined film 133 is preferably 0.1 μm or more and 0.3 μm or less. Accordingly, it is possible to easily break a part of the predetermined film 133 while maintaining a function of protecting the flavor source 131 by the predetermined film 133.
As described above, although the predetermined film 133 is formed integrally with the filter 132, the predetermined film 133 is bonded to the filter 132 by paste or the like. Or, by setting the outer shape of the predetermined film 133 smaller than that of the filter 132 in the vertical direction with respect to the predetermined direction A, the filter 132 may be stuffed into the predetermined film 133 and may be fitted into the predetermined film 133 by a restoring force of the filter 132. Alternatively, the filter 132 may be provided with an engagement part for engaging the predetermined film 133.
A shape of the predetermined film 133 is not particularly limited, but preferably has a concave shape in the vertical cross-section with respect to the predetermined direction A. In such a case, after filling the flavor source 131 inside the predetermined film 133 having the concave shape, an opening of the predetermined film 133 filled with the flavor source 131 is closed by the filter 132.
When the predetermined film 133 has the concave shape in the vertical cross-section with respect to the predetermined direction A, a maximum sectional area (i.e., a sectional area of an opening in which the filter 132 is fitted) of the sectional area of the space surrounded by the predetermined film 133, is preferably 25 mm2 or more and 80 mm2 or less, more preferably, 25 mm2 or more and 55 mm2 or less. In such a case, in the vertical cross-section with respect to the predetermined direction A, a sectional area of the filter 132 is preferably 25 mm2 or more and 55 mm2 or less. A thickness of the filter 132 in the predetermined direction A is preferably 3.0 mm or more and 7.0 mm or less.
The inhalation unit 140 has an inhalation hole 141. The inhalation hole 141 is an opening to expose the filter 132. A user inhales flavor together with aerosol by inhaling aerosol through the inhalation hole 141.
In the first embodiment, the inhalation unit 140 is configured to be attachable/detachable to/from the outer wall 124 of the atomizing unit 120. For example, the inhalation unit 140 has a cup shape configured to be fitted to an inner surface of the outer wall 124. However, the embodiment is not limited to this. The inhalation unit 140 may be attached rotatably to the outer wall 124 with a hinge or the like.
In the first embodiment, the inhalation unit 140 is provided separately from the capsule unit 130. In other words, the inhalation unit 140 constitutes a part of the main body unit. However, the embodiment is not limited to this. The inhalation unit 140 may be provided integrally with the capsule unit 130. In such a case, it is noted that the inhalation unit 140 constitutes a part of the capsule unit 130.
(Control circuit)
Hereinafter, a control circuit according to a first embodiment will be explained.
As shown in
The puff detector 51 is connected to a sensor 20 that detects a wind pressure generated by an inhalation behavior of a user. The puff detector 51 detects a puff state based on the detection results of the sensor 20 (e.g., a negative pressure within the non-burning type flavor inhaler 100). Especially, the puff detector 51 detects a puff state inhaling an aerosol and a non-puff state not inhaling an aerosol. Thus, the puff detector 51 can specify the number of puff actions of inhaling aerosol. Further, the puff detector 51 can detect time required per one puff action of inhaling aerosol.
The light-emitting element control unit 52 is connected to the light-emitting element 40 and the puff detector 51, and controls the light-emitting element 40. Specifically, the light-emitting element control unit 52 controls the light-emitting element 40 in a first light-emitting mode, in a puff state inhaling an aerosol. On the other hand, the light-emitting element control unit 52 controls the light-emitting element 40 in a second light-emitting mode different from the first light-emitting mode, in a non-puff state not inhaling an aerosol.
Here, a light-emitting mode is defined by combination of parameters such as the amount of light of the light-emitting element 40, the number of light-emitting elements 40 in a lighting state, a color of the light-emitting element 40, and a cycle of repeating turning on and turning off of the light-emitting element 40. A different light-emitting mode means a light-emitting mode that any of the above parameters is different.
In the first embodiment, a second light-emitting mode changes according to the number of puff actions of inhaling aerosol. A first light-emitting mode may change according to the number of puff actions of inhaling aerosol, or may be constant without depending on the number of puff actions of inhaling aerosol.
For example, the first light-emitting mode is such a mode for lighting a red light-emitting element 40 to simulate a feeling of a general cigarette that generates an aerosol along with burning. The first light-emitting mode is preferably such a mode for continuously lighting the light-emitting element 40. The first light-emitting mode may be a mode of repeating turning on and turning off of the light-emitting element 40 at a first cycle. Preferably, the first light-emitting mode may be a mode for lighting a color different from a color of burning a general cigarette, i.e. a green light-emitting element 40, when emphasis on the use of the non-burning type flavor inhaler which is different from the cigarette.
For example, the second light-emitting mode is such a mode for lighting a color different from the first light-emitting mode, i.e. a blue light-emitting element 40 to notify a user that an aerosol source is not heated. The second light-emitting mode may be a mode of repeating turning on and turning off of the light-emitting element 40 at a second cycle different from the first cycle. For example, the second light-emitting mode may be a mode of repeating turning on and turning off of the light-emitting element 40 at a second cycle longer than the first cycle. In such a case, the second light-emitting mode may involve a color same as or different from the first light-emitting mode.
As described above, the second light-emitting mode changes according to the number of puff actions of inhaling aerosol.
For example, the second light-emitting mode may be a mode of increasing the number of the light-emitting elements 40 to be controlled along with an increase in the number of puff actions. For example, the light-emitting element control unit 52 controls one light-emitting element 40 in the second light-emitting mode in a first puff action, and controls two light-emitting elements 40 in the second light-emitting mode in a second puff action. Alternatively, the light-emitting element control unit 52 controls the n number of light-emitting elements 40 in the second light-emitting mode in a first puff action, and controls the n−1 number of light-emitting elements 40 in the second light-emitting mode in a second puff action.
The second light-emitting mode may be a mode for increasing or decreasing the amount of light of the light-emitting element 40 by adjusting the power amount supplied to the light-emitting element 40 along with an increase in the number of puff actions. Alternatively, the second light-emitting mode may be a light-emitting mode for changing the color of the light-emitting element 40 along with an increase in the number of puff actions.
Even in the case that the first light-emitting mode changes depending on the number of puff actions, the concept of the change of the first light-emitting mode is basically the same as the change of the second light-emitting mode.
In the first embodiment, when the number of puff actions of inhaling aerosol reaches a predetermined number (e.g., eight times), the light-emitting element control unit 52 terminates the control according to the first light-emitting mode and the second emitting mode, and controls the light-emitting element 40 in an emission end mode.
The emission end mode may be a mode to notify a user of the timing to end a puff action, and is preferably different from the first lighting-emitting mode and the second light-emitting mode. For example, the emission end mode is such a mode that the amount of light of the light-emitting element 40 is smaller than that in the first and second light-emitting modes and that the amount of light of the light-emitting element 40 is gradually decreased.
The heat source control unit 53 is connected to the power source 10, and controls the power amount supplied to the heat source 80 from the power source 10. Note that the power amount is a multiplied result of time and power (voltage or current) and a value controlled by the time and the power. For example, the heat source control unit 53 controls the voltage applied to the heat source 80 from the power source 10 by controlling a DC-DC converter that is added to the power source 10.
First, the heat source control unit 53 increases the power amount supplied to the heat source 80 stepwise from a reference power amount along with an increase in the number of puff actions of inhaling aerosol. Thus, it is possible to simulate a feeling of a general cigarette that generates an aerosol along with burning.
When a puff action is performed after the number of puffs exceeds a predetermined number, the heat source control unit 53 may control the power source 10 to supply the heat source 80 with the power amount smaller than the reference power amount. Thus, a user can inhale a little amount of aerosol even at the timing to end a puff action, increasing the user's satisfaction.
When a predetermined time elapses after the number of puff actions exceeds a predetermined number, the heat source control unit 53 turns off the non-burning type flavor inhaler 100. This suppresses waste of the power amount of the non-burning type flavor inhaler 100 due to forgetting to turn off the power.
The heat source control unit 53 may supply the heat source 80 with power amount smaller than the reference power amount by combining the above operations after the number of puff action exceeds a predetermined number, and may turn off the power of the non-burning type flavor inhaler 100 when a predetermined time elapses after the number of puff actions exceeds the predetermined number.
Moreover, the power of the non-burning type flavor inhaler 100 may be forced to turn off by the predetermined action of the pushbutton 30 (i.e. an action for long press of the pushbutton 30) regardless of the control of the heat source control unit 53. That is, the power of the non-burning type flavor inhaler 100 may be forced to turn off by the predetermined action of the pushbutton 30 (i.e. an action for long press of the pushbutton 30) before the puff action reaches the predetermined time.
The heat source control unit 53 preferably increases a gradient of the power amount supplied to the heat source 80 in accordance with an increase in the number of puff actions for inhaling aerosol. Here, a gradient of power amount is defined by the number of puff actions that maintains the constant power amount and by the increment step of power amount. In other words, along with an increase in the number of puff actions, the number of puff actions that maintains the constant power amount decreases. Alternatively, along with an increase in the number of puff actions, the increment step of power amount increases. Alternatively, along with an increase in the number of puff actions, the number of puff actions that maintains constant power amount decreases, and the increment step of power amount increases.
Further, the heat source control unit 53 may control a first mode using a first reference power amount as the reference power amount and a second mode using a second reference power amount greater than a first reference power amount as the reference power amount. As a reference power amount, a reference power amount of three or more steps may be prepared. In such a case, a reference power amount may be switched by operating the pushbutton 30. For example, the first mode is selected by pressing the pushbutton 30 once, and the second mode is selected by pressing the pushbutton 30 twice. The pushbutton 30 may be replaced to a touch sensor. By these operations, the power of the non-burning type flavor inhaler 100 may be turned on. In other words, turning on the power source and switching the reference power amount may be performed by one operation of the pushbutton 30. The operation of turning on the power source by operation of the pushbutton 30 may be separated from the operation of switching the reference power amount.
Second, the heat source control unit 53 controls a standard mode to be applied to a user whose required time per one puff action of inhaling aerosol is within a standard required time duration, and a reduced mode to be applied to a user whose required time per one puff action of inhaling aerosol is shorter than a standard required time duration. Here, a standard required time duration means a time duration that the balance of the inhaled amount of aerosol (TPM: Total Particulate Matter) is particularly excellent.
In particular, in one puff action in the standard mode, the heat source control unit 53 controls the power source 10 to supply the heat source 80 with a standard power amount in the duration before first duration elapses, and controls the power source 10 to supply the heat source 80 with power amount smaller than the standard power amount in the duration after first duration elapses. The power amount smaller than the standard power amount is a concept including zero, the heat source control unit 53 may immediately zero the power amount supplied to the heat source 80, i.e. may immediately stop the power supply to the heat source 80, in the duration after the first duration elapses. Alternately, the heat source control unit 53 may gradually decrease the power amount supplied to the heat source 80.
Here, the first duration is preferably the same as an end timing of the standard required time duration. However, the first duration may be longer than the end timing of the standard required time within a range that the balance of the supplied amount of aerosol (TPM) is allowed.
On the other hand, in one puff action in the reduced mode, the heat source control unit 53 controls the power source 10 to supply the heat source 80 with first power amount greater than the standard power amount in the duration before second duration elapses, and controls the power source 10 to supply the heat source 80 with second power amount smaller than the first power amount in the duration until third duration elapses after the second duration, and controls the power source 10 to supply the heat source 80 with power amount smaller than the second power amount in the duration after the third duration elapses. The power amount smaller than the second power amount is a concept including zero, the heat source control unit 53 may immediately zeros the power amount supplied to the heat source 80, i.e. may immediately stop the power supply to the heat source 80, in the duration after the third duration elapses. Alternately, the heat source control unit 53 may gradually decrease the power amount supplied to the heat source 80.
Here, the second duration is preferably shorter than a start timing of the standard required time duration. In other words, the second duration used in the reduced mode is preferably shorter than the first duration used in the standard mode. The second duration may be included in the standard required time duration, or may be longer than the end timing of the standard required time duration. The third duration is preferably the same as the end timing of the standard required time duration. The third duration may be longer than the end timing of the standard required time duration within a range that the balance of the supplied amount of aerosol (TPM) is allowed. The second power amount smaller than the first power amount may be the same as the standard power amount. The second power amount may either be greater than or smaller than the standard power amount.
As described above, as the number of puff actions increases, the heat source control unit 53 increases the power amount supplied to the heat source 80 stepwise from a reference power amount. In other words, it is noted that the standard power amount in one puff action increases along with an increase in the number of puff actions.
The heat source control unit 53 may set the standard mode or the reduced mode according by learning a user's puff action. In particular, when the time required per one puff action acquired by the learning is within the standard required time duration, the heat source control unit 53 sets the standard mode. When the time required per one puff action acquired by the learning is shorter than the standard required time duration, the heat source control unit 53 sets the reduced mode.
In the first embodiment, the atomizing unit 120 is attachable/detachable to/from the electrical unit 110. The capsule unit 130 is attachable/detachable to/from the main body unit including the electrical unit 110. In other words, the electrical unit 110 can be reused over multiple puff action series. A puff action series means a series of behaviors to repeat a predetermined number of puff actions. Therefore, by learning the time required per one puff action in a first puff action series, the standard mode or the reduced mode may be set in second and subsequent puff action series. Or, in one puff action series, by learning the time required per one puff action in the first n times of puff actions, the standard mode or the reduced mode may be set for the puff actions on and after n+1 (or, N+2) times.
Alternatively, the heat source control unit 53 may set the standard mode or the reduced mode according to the operation of a user. In such a case, a switch for switching the standard mode and the reduced mode is provided in the non-burning type flavor inhaler 100. It is permitted to switch the standard mode and the reduced mode in one puff action series. Alternatively, a mode that is set first may be fixedly applied without permitting switching of the standard mode and the reduced mode in one puff action series.
(Light-Emitting Mode)
Hereinafter, an example of a light-emitting mode according to the first embodiment will be explained.
First, a first example of a light-emitting mode will be explained with reference to
For example, as shown in
On the other hand, in the puff states #1 to #8, the light-emitting mode #1 is used as a first light-emitting mode. In the 9th puff state or later, the light-emitting mode #1 may be used as a first light-emitting mode, or a light-emitting mode different from the first light-emitting mode and the second light emitting mode may be used to indicate that the puff exceeds eight times (predetermined number of times).
The light-emitting modes #1, #2-1, #2-2, #2-3 and the emission end mode are different each other. As described above, a light-emitting mode is defined by combination of parameters such as the amount of light of the light-emitting element 40, the number of light-emitting elements 40 in a lighting state, a color of the light-emitting element 40, and a cycle of repeating turning on and turning off of the light-emitting element 40. A different light-emitting mode means a light-emitting mode that any of the above parameters is different.
For example, the light-emitting mode #1 is preferably such a mode for imaging burning in order to simulate a feeling of a general cigarette that generates an aerosol along with burning. The light-emitting mode #2-1 is preferably such a mode for imaging the beginning of a puff action series. The light-emitting mode #2-2 is preferably such a mode for imaging the middle of a puff action series. The light-emitting mode #2-3 is preferably such a mode for imaging the end of a puff action series. The emission end mode is preferably such a mode to notify a user the timing to end a puff action.
Second, a first example of a light-emitting mode will be explained with reference to
For example, as shown in
On the other hand, in the puff states #1 to #4, the light-emitting mode #1-1 is used as a first light-emitting mode. In the puff states #5 to #7, the light-emitting mode #1-2 is used as a first light-emitting mode. In the puff state #8, the light-emitting mode #1-3 is used as a first light-emitting mode. In the 9th and subsequent puff states, the light-emitting mode #1-4 is used.
The light-emitting mode #1-1 is preferable such a light-emitting mode for imaging the beginning of a puff action series. The light-emitting mode #1-2 is preferably such a light-emitting mode for imaging the middle of a puff action series. The light-emitting mode #1-3 is preferably such a light-emitting mode for imaging the end of a puff action series. The light-emitting mode #1-4 is, like the emission end mode, preferably such a mode to notify a user the timing to end a puff action.
In the first embodiment, as shown in
(Power Control in a Puff Action Series)
Hereinafter, an example of power control in a puff action series according to the first embodiment will be explained.
Here, a case where the power amount supplied to the heat source 80 is controlled by the voltage applied to the heat source 80. Therefore, the power amount and the voltage can be considered as the same meaning in the first embodiment.
As shown in
As described above, the heat source control unit 53 increases a gradient of the voltage applied to the heat source 80 along with an increase in the number of puff actions of inhaling aerosol.
For example, as the number of puff actions increases, the number of puff actions that maintains a constant voltage decreases. In other words, the number of puff actions that a reference voltage is applied is four times, the number of puff actions that a voltage of one step greater than a reference voltage is applied is three times, and the number of puff actions that a voltage of two steps greater than a reference voltage is applied is one time. Alternatively, as the number of puff actions increases, the number of puff actions that maintains a constant voltage decreases. Alternatively, an increase width Y of second time voltage is greater than an increase width X of a first time voltage.
Thus, the gradient of voltage (θ1 and θ2), which is defined by the number of puff actions that maintains a constant voltage and by the increase width of voltage, increases along with an increase in the number of puff actions. In other words, the gradient θ2 in the middle of a puff action series is greater than the gradient θ1 at the beginning of a puff action series.
In
(Power Control in One Puff Action)
Hereinafter, an example of power control in a puff action series according to the first embodiment will be explained.
Here, a case where the power amount supplied to the heat source 80 is controlled by the voltage applied to the heat source 80. Therefore, the power and the voltage can be considered as the same meaning in the first embodiment.
As shown in
Here, the case where the first duration T1 is the same as the end timing of the standard required time duration is shown. However, as described above, the first duration T1 is not limited to this.
As shown in
Here, the case where the second duration is shorter than the start timing of the standard required time duration is shown. The case where the third duration is the same as the end timing of the standard required time duration is shown. The case where the second voltage is smaller than the standard voltage is shown. However, the second duration T2, the third duration T3 and the second voltage are not limited to those described above.
In the case where the standard mode or the reduced mode is set, the time required per one puff action may be changed. Even in such a case, it is noted that the voltage profile shown in
(Function and Effect)
In the first embodiment, in a non-puff state not inhaling an aerosol, the light-emitting element control unit 52 controls the light-emitting element 40 in the second light-emitting mode different from the first light-emitting mode. Thus, even in a non-puff state, a user can grasp whether or not the non-burning type flavor inhaler 100 is in a usable state. Further, as a light-emitting mode in a puff state is different from a light-emitting mode in a non-puff state, it is possible to realize a feeling similar to a general cigarette that generates an aerosol along with burning.
In the first embodiment, the second light-emitting mode changes according to the number of puff actions of inhaling aerosol. Thus, a user can easily grasp a progress status of a puff according to the change of the second light-emitting mode, in a non-puff state easy to visually recognize lighting of the light-emitting element 40.
In the first embodiment, the heat source control unit 53 increases the power amount supplied to the heat source 80 stepwise from a reference power amount along with an increase in the number of puff actions of inhaling aerosol. Thus, it is possible to bring the aerosol inhalation amount close to a general cigarette that generates an aerosol along with burning, and realize a feeling similar to a general cigarette.
In the first embodiment, the heat source control unit 53 controls a first mode using a first power amount as a reference power amount, and a second mode using a second power amount greater than the first power amount as a reference power amount. Thus, a user can select the amount of aerosol depending on the taste by one non-burning type flavor inhaler 100.
In the first embodiment, as the reduced mode is used, even such a user whose required time per one puff action is shorter than the standard required time can increase the satisfaction by increasing a temperature of the heat source faster than in the standard mode. Regardless of an operation mode, as the power amount supplied to the heat source is decreased in duration after the first duration or the third duration elapses, it is possible to prevent inhalation of decomposed substance and reduction of smoking taste.
In the first embodiment, a predetermined operation mode (standard mode and reduced mode) is prepared, and it is sufficient to control the power amount supplied to the heat source according to the predetermined operation mode. Thus, a complex control that continues controlling such supplied amount of power based on the airflow (amount of inhalation) is not necessary while the power is being supplied to the heat source 80. In other words, it is possible to suppress the reduction of smoking taste, and to increase the user's satisfaction with a simple configuration.
In the first embodiment, the push button 30 is provided for switching turn on and off of the non-burning type flavor inhaler 100. Since the user can intentionally start or stop the puff action series, it is possible to realize a feeling similar to the general cigarette that generates an aerosol along with burning (a feeling of drawing line on each puff action series).
In the first embodiment, the push button 30 is provided for turning off the non-burning type flavor inhaler 100, thereby the consumption power can be reduced since the power needs not to be supplied to the sensor 20 and the light-emitting element 40 in non-used state of the non-burning type flavor inhaler 100. On the other hand, even if the push button 30 is provided for reducing the consumption power, user can grasp whether the non-burning type flavor inhaler 100 is turned on or not by the lighting mode of the light-emitting element 40. In detail, the light-emitting element 40 lights on in the non-puff stated addition to the puff state, the user can grasp the turn on of the non-burning type flavor inhaler 100 if the light-emitting element 40 emits the light, and the user can grasp the turn off of the non-burning type flavor inhaler 100 if the light-emitting element 40 does not emit the light.
[Modification 1]
Hereinafter, a modification 1 of the first embodiment will be described. Hereinafter, differences between the first embodiment and the modification 1 will be mainly described.
Specifically, in the first embodiment, the heat source control unit 53 controls the power amount supplied to the heat source 80 from the power source 10 by controlling the voltage applied to the heat source 80 from the power source 10. In detail, the heat source control unit 53 increases the power amount (voltage) supplied to the heat source 80 stepwise from the reference power amount (reference voltage) along with the increase in the number of puff actions of inhaling aerosol (see
In contrast, in the modification 1, the heat source control unit 53 controls the voltage applied to the heat source 80 from the power source 10 by a pulse control, and controls the power amount supplied to the heat source 80 from the power source 10 by controlling a pulse width (duty ratio) of the voltage applied to the heat source 80. In detail, the heat source control unit 53 shortens the pulse width of the voltage applied to the heat source 80 from a reference pulse width along with the increase in the number of puff actions of inhaling aerosol (see
In the
[Modification 2]
Hereinafter, a modification 2 of the first embodiment will be described. Hereinafter, differences between the first embodiment and the modification 2 will be mainly described.
Specifically, in the first embodiment, the heat source control unit 53 controls the power amount supplied to the heat source 80 from the power source 10 by controlling the voltage applied to the heat source 80 from the power source 10. In detail, the heat source control unit 53 increases the power amount (voltage) supplied to the heat source 80 stepwise from the reference power amount (reference voltage) along with the increase in the number of puff actions of inhaling aerosol (see
In contrast, in the modification 2, the heat source control unit 53 controls the power amount supplied to the heat source 80 from the power source 10 by controlling a time period of the voltage applied to the heat source 80 from the power source 10. In detail, the heat source control unit 53 lengthens the time period of the voltage applied to the heat source 80 from a reference time period along with the increase in the number of puff actions of inhaling aerosol (see
In the modification 2, the reference time period means the maximum time of the continuous voltage application to the heat source 80 while the user continues the puff action. Therefore, the voltage application to the heat source 80 is stopped when a time that the user continues the puff action exceeds the reference time period. The first light-emitting mode continues while the puff action of the user continues even if the voltage application is stopped. Thereby, the effect same with the case shown in
When the standard mode and the reduced mode are introduced, the first duration, the second duration and the third duration may be adjusted (extended) along with the increase in the number of puff actions of inhaling aerosol.
The present invention has been explained according to the embodiment described hereinbefore. However, the description and drawings constituting a part of the disclosure are not to be understood to limit the invention. Various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art from this disclosure.
In the embodiment, the capsule unit 130 is used as a member for containing the flavor source 131. However, the embodiment is not limited to this. The member for containing the flavor source 131 may be a member at least having a structure that can deliver the aerosol to the user via the flavor source 131 (a structure that the aerosol generating source and the outlet is communicated via the flavor source), when it becomes a usable state that the member is connected to the main body unit. For example, it may be a cartridge. In such a case, the cartridge includes a cylindrical member, a pair of filters each provided at respective end of the cylindrical member, and a flavor source 131 filled in a space partitioned by the cylindrical member and the pair of filters.
Although not specifically mentioned in the embodiment, the number of puff actions may be corrected by the value (amount of generated aerosol) defined by the time required per one puff action and by the power amount supplied to the heat source 80. In particular, when the amount of aerosol generated in one puff action is smaller than a predetermined value, the number of puff actions may be accumulated by adding a predetermined coefficient α (α<1) to the value multiplied in one time. On the other hand, when the amount of aerosol generated in one puff action is greater than a predetermined value, the number of puff actions may be accumulated by adding a predetermined coefficient β (β>1) to the value multiplied in one time. Namely, the number of puff actions may not necessarily be an integer.
Although not specifically mentioned in the embodiment, the timing to increase the power amount supplied to the heat source 80 in power control in a puff action series is preferably synchronized with the timing to change the second light-emitting mode. For example, as shown in
Although not specifically mentioned in the embodiment, as shown in
In the embodiment, there is provided a first mode using a first power amount as a reference power amount (Low mode in
Although not specifically mentioned in the embodiment, the switching of the puff action series preferably performed as follow.
(a) A case where the non-burning type flavor inhaler 100 automatically turned off by the control of the control circuit 50 when the number of puff actions in the puff action series reaches the predetermined number of times
In such a case, the new puff action series starts when the non-burning type flavor inhaler 100 turned on again.
(b) A case where the non-burning type flavor inhaler 100 automatically turned off by the control of the control circuit 50 when the inhalation is not performed for a predetermined period (for example, shortest period among “a predetermined number*60 seconds”, “15 minutes” and “a time from when the number of puff actions exceeds the predetermined number of times to when it turned off automatically (i.e. the above predetermined times)*2”) before the number of puff actions in the puff action series reaches the predetermined number of times
In such a case, the new puff action series starts when the number of puff actions is equal to or more than a switch determination times (i.e. ½ or the predetermined times). On the other hand, the previous puff action series continues when the number of puff actions is less than a switch determination times (i.e. ½ or the predetermined times).
(c) A case where the non-burning type flavor inhaler 100 forced to turn off by the predetermined action of the pushbutton 30 (i.e. an action for long press of the pushbutton 30)
In such a case, the new puff action series starts when the non-burning type flavor inhaler 100 turned on again. Alternately, it may be selectable for user to start the new puff action series or continue the previous puff action series when the non-burning type flavor inhaler 100 turned on again.
In the cases (a) and (c) described above, the number of the puff actions counted during the puff action series may be reset at the timing of turning off the non-burning type flavor inhaler 100. Alternately, the number of the puff actions counted during the puff action series may be reset at the timing of turning on the non-burning type flavor inhaler 100 again. In the case (c) described above, if a configuration is introduced that the user can select to start the new puff action series or continue the previous puff action series, the number of the puff actions counted during the puff action series may be reset when the non-burning type flavor inhaler 100 is turned on again and the user selects to start the new puff action series.
On the other hand, in the case (b) described above, the number of the puff actions counted during the puff action series may be reset when the number of puff actions is equal to or more than the switch determination times and the non-burning type flavor inhaler 100 is turned off. Alternately, the number of the puff actions counted during the puff action series may be reset when the number of puff actions is equal to or more than the switch determination times and the non-burning type flavor inhaler 100 is turned on again.
In the embodiment, a case is exampled that the pushbutton 30 is provided as a user interface for turning on or turning off the power of the non-burning type flavor inhaler 100. However, the embodiment is not limited to this. The user interface for turning on or turning off the power of the non-burning type flavor inhaler 100 may be a hardware switch enables to turning on or turning off the non-burning type flavor inhaler 100 without power consumption.
In the embodiment, the non-burning type flavor inhaler 100 is exampled that including the pushbutton 30 for turning on. However, the embodiment is not limited to this. The non-burning type flavor inhaler 100 may not include the pushbutton 30 for turning on. In such a case, the end of the puff action series may be notified to the user by only the emission end mode of the light-emitting element 40 instead of turning off the non-burning type flavor inhaler 100 like the above described embodiment, when the number of puff actions exceeds the predetermined number of times and the predetermined time elapses. Similarly, the control may be performed that the power supply to the heater source 80 is restricted even if the sensor 20 detects the user inhalation for a predetermined period (i.e. 5 minutes) instead of turning off the non-burning type flavor inhaler 100.
Although the heat source 80 is exampled as the atomizer atomizing the aerosol source without burning in the embodiment, the embodiment is not limited to this. The atomizer atomizing the aerosol source without burning may be a unit atomizing the aerosol source by ultrasonic.
