The suction device according to the present embodiment heats the contents contained in the base material to generate a substance to be sucked by the user. In particular, the suction device according to the present embodiment produces an aerosol by heating a base material containing an aerosol source from the inside of the base material. Aerosols are an example of substances that are inhaled by the user. The aerosol source is an example of the contents contained in the substrate. Alternatively, the substance produced by the suction device may be a gas. Hereinafter, the user sucking the substance produced by the suction device is also simply referred to as "suction" or "puff". Hereinafter, each configuration example of the suction device will be described. Hereinafter, a configuration example of the suction device according to the present embodiment will be described with reference to FIG.

FIG. 1 is a schematic diagram schematically showing a configuration example of a suction device. As shown in FIG. 1, the suction device 100 according to this configuration example includes a power supply unit 111, a sensor unit 112, a notification unit 113, a storage unit 114, a communication unit 115, a control unit 116, a heating unit 121, a compression unit 160, and a holding unit. Including part 140. The user sucks the stick-type base material 150 while the stick-type base material 150 is held by the holding portion 140. Hereinafter, each component will be described in order.

The power supply unit 111 stores electric power. Then, the power supply unit 111 supplies electric power to each component of the suction device 100. The power supply unit 111 may be composed of, for example, a rechargeable battery such as a lithium ion secondary battery. The power supply unit 111 may be charged by being connected to an external power supply by a USB (Universal Serial Bus) cable or the like. Further, the power supply unit 111 may be charged in a state of being disconnected from the device on the power transmission side by the wireless power transmission technology. Alternatively, only the power supply unit 111 may be removed from the suction device 100, or may be replaced with a new power supply unit 111.

The sensor unit 112 detects various information related to the suction device 100. Then, the sensor unit 112 outputs the detected information to the control unit 116. As an example, the sensor unit 112 is composed of a pressure sensor such as a microphone capacitor. Then, when the sensor unit 112 detects the negative pressure due to the suction by the user, the sensor unit 112 outputs information indicating that the suction by the user has been performed to the control unit 116. As another example, the sensor unit 112 is composed of an input device such as a button or a switch that receives input of information from the user. In particular, the sensor unit 112 may include a button instructing the start / stop of aerosol production. Then, the sensor unit 112 outputs the information input by the user to the control unit 116. As another example, the sensor unit 112 is composed of a temperature sensor that detects the temperature of the heating unit 121. Such a temperature sensor detects the temperature of the heating unit 121 based on, for example, the electric resistance value of the conductive track of the heating unit 121. The sensor unit 112 may detect the temperature of the stick-type base material 150 held by the holding unit 140 based on the temperature of the heating unit 121.

The notification unit 113 notifies the user of the information. As an example, the notification unit 113 is composed of a light emitting device such as an LED (Light Emitting Diode). In that case, the notification unit 113 emits light in different light emission patterns when the state of the power supply unit 111 requires charging, when the power supply unit 111 is charging, or when an abnormality occurs in the suction device 100. .. The light emission pattern here is a concept including color, lighting / extinguishing timing, and the like. The notification unit 113 may be composed of a display device for displaying an image, a sound output device for outputting sound, a vibrating vibration device, or the like, together with or in place of the light emitting device. In addition, the notification unit 113 may notify information indicating that suction by the user has become possible. Information indicating that suction by the user has become possible is notified when the temperature of the stick-type base material 150 heated by the heating unit 121 reaches a predetermined temperature.

The storage unit 114 stores various information for the operation of the suction device 100. The storage unit 114 is composed of a non-volatile storage medium such as a flash memory. An example of the information stored in the storage unit 114 is information related to the OS (Operating System) of the suction device 100, such as the control contents of various components by the control unit 116. Another example of the information stored in the storage unit 114 is information related to suction by the user, such as the number of suctions, the suction time, and the cumulative suction time.

The communication unit 115 is a communication interface for transmitting and receiving information between the suction device 100 and another device. The communication unit 115 performs communication conforming to any wired or wireless communication standard. As such a communication standard, for example, a wireless LAN (Local Area Network), a wired LAN, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like can be adopted. As an example, the communication unit 115 transmits the information on the suction by the user to the smartphone in order to display the information on the suction by the user on the smartphone. As another example, the communication unit 115 receives new OS information from the server in order to update the OS information stored in the storage unit 114.

The control unit 116 functions as an arithmetic processing unit and a control device, and controls the overall operation in the suction device 100 according to various programs. The control unit 116 is realized by, for example, an electronic circuit such as a CPU (Central Processing Unit) and a microprocessor. In addition, the control unit 116 may include a ROM (Read Only Memory) for storing programs to be used, calculation parameters, and the like, and a RAM (Random Access Memory) for temporarily storing parameters and the like that change as appropriate. The suction device 100 executes various processes based on the control by the control unit 116. Power is supplied from the power supply unit 111 to each of the other components, charging of the power supply unit 111, detection of information by the sensor unit 112, notification of information by the notification unit 113, storage and reading of information by the storage unit 114, and communication unit 115. The transmission and reception of information is an example of processing controlled by the control unit 116. Compression and decompression (compression stop) by the compression unit 160 is also an example of processing controlled by the control unit 116. Other processes executed by the suction device 100, such as input of information to each component and processing based on the information output from each component, are also controlled by the control unit 116.

The holding portion 140 forms an internal space 141, and holds the stick-type base material 150 while accommodating a part of the stick-type base material 150 in the internal space 141. The holding portion 140 has an opening 142 that communicates the internal space 141 to the outside, and holds the stick-type base material 150 inserted into the internal space 141 from the opening 142. For example, the holding portion 140 is a tubular body having an opening 142 and a bottom portion 143 as a bottom surface, and defines a columnar internal space 141. The holding portion 140 also has a function of defining a flow path of air supplied to the stick-type base material 150. The air inflow hole, which is the inlet of the air into the flow path, is arranged at, for example, the bottom 143. On the other hand, the air outflow hole, which is an outlet for air from such a flow path, is an opening 142.

The stick-type base material 150 is a stick-type member. The outer circumference of the stick-type base material 150 is formed by being wound by a sheet-like member. An example of a sheet-shaped member is rolling paper. The stick-type base material 150 includes a base material portion 151 and a mouthpiece portion 152.

The base material portion 151 contains an aerosol source. The aerosol source is atomized by heating to produce an aerosol. Aerosol sources are, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquids such as water. The aerosol source may further comprise a tobacco ingredient or an extract derived from the tobacco ingredient that releases the flavor component when heated. If the aspirator 100 is a medical inhaler, the aerosol source may include a drug for the patient to inhale. The aerosol source is not limited to a liquid, but may be a solid. At least a part of the base material portion 151 is housed in the internal space 141 of the holding portion 140 in a state where the stick-type base material 150 is held by the holding portion 140.

In particular, the aerosol source is contained in an object having an arbitrary shape such as a particle or a sheet, and is filled in the base material portion 151. The object containing the aerosol source is also referred to as a base material element below. The base material element is filled in the base material portion 151 with a gap so as not to block the air flow path.

The mouthpiece 152 is a member that can be held by the user during suction. At least a part of the mouthpiece 152 protrudes from the opening 142 while the stick-type base material 150 is held by the holding part 140. Then, when the user holds and sucks the suction port portion 152 protruding from the opening 142, air flows into the inside of the holding portion 140 through an air inflow hole (not shown). The inflowing air passes through the internal space 141 of the holding portion 140 and reaches the user's mouth together with the aerosol generated from the base material portion 151.

The heating unit 121 heats the aerosol source to atomize the aerosol source and generate an aerosol. The heating unit 121 is made of any material such as metal or polyimide. For example, the heating portion 121 is formed in an arbitrary shape such as a blade shape or a columnar shape (for example, a needle shape), and is arranged so as to project from the bottom portion 143 of the holding portion 140 to the internal space 141 of the holding portion 140. Therefore, when the stick-type base material 150 is inserted into the holding portion 140, the heating portion 121 is inserted into the stick-type base material 150 so as to pierce the base material portion 151 of the stick-type base material 150. Then, when the heating unit 121 generates heat, the aerosol source contained in the stick-type base material 150 is heated from the inside of the stick-type base material 150 and atomized to generate an aerosol. The heating unit 121 generates heat when power is supplied from the power supply unit 111. As an example, when the sensor unit 112 detects that a predetermined user input has been performed, power may be supplied to generate an aerosol. When the temperature of the stick-type base material 150 heated by the heating unit 121 reaches a predetermined temperature, suction by the user becomes possible. After that, when the sensor unit 112 detects that a predetermined user input has been performed, or when a predetermined time has elapsed, the power supply may be stopped. As another example, power may be supplied to generate an aerosol during a period in which the sensor unit 112 detects that suction has been performed by the user.

The heating performed until the temperature of the stick-type base material 150 reaches a predetermined temperature is also called preheating. Further, such a predetermined temperature is also referred to as a suctionable temperature. The time required to reach the suctionable temperature is also referred to as the preheating time below. Even after the temperature of the stick-type base material 150 reaches the suctionable temperature by the preheating, heating for maintaining the temperature can be performed.

The compression unit 160 compresses the stick-type base material 150 held by the holding unit 140. In particular, the compression unit 160 compresses the portion to be heated, which is the portion of the stick-type base material 150 held by the holding unit 140 that is heated by the heating unit 121, from the outer periphery toward the heating unit 121 in the direction 190. The base material portion 151 is an example of a portion to be heated. In the following, such a direction is also referred to as a compression direction 190. The state in which the compression unit 160 compresses the stick-type base material 150 is also referred to as a compressed state. The state in which the compression unit 160 does not compress the stick-type base material 150 is also referred to as an open state. The detailed configuration of the compression unit 160 will be described in detail below.

The compression direction 190C is a direction from the compression unit 160C to the heating unit 121.

The insertion / removal direction 191 is a direction in which the stick-type base material 150 is inserted into or pulled out from the suction device 100. Of the insertion / extraction directions 191, the direction in which the stick-type base material 150 is inserted is also referred to as the insertion direction 191A. Of the insertion / extraction directions 191, the direction in which the stick-type base material 150 is pulled out is also referred to as the pull-out direction 191B. The insertion / removal direction 191 is orthogonal to the plurality of compression directions 190A to 190C. The stick-type base material 150 is inserted into the suction device 100 so that the longitudinal direction of the stick-type base material 150 coincides with the insertion / removal direction 191.

The direction of rotation with the insertion / extraction direction 191 as the rotation axis is also referred to as the rotation direction 192. Of the rotation directions 192, the clockwise direction in the state of facing the insertion direction 191A is also referred to as a right rotation direction 192A. Of the rotation directions 192, the counterclockwise direction in the state of facing the insertion direction 191A is also referred to as a left rotation direction 192B.

Hereinafter, the features of the compression unit 160 will be described in detail while explaining each component shown in FIGS. 2 to 5 in order. However, in the description, the features related to the compression unit 160A may be described as a representative. Of course, the compression unit 160B and the compression unit 160C have the same characteristics as those relating to the compression unit 160A.

The edge portion 171 is a member that covers the edge of the opening 142 of the holding portion 140. The edge portion 171 is formed in a cylindrical tubular shape. The edge portion 171 is arranged at the end portion of the inner wall portion 172 and the second rotating portion 175 on the pull-out direction 191B side.

The inner wall portion 172 is a member that constitutes the inner wall of the internal space 141 of the holding portion 140. The inner wall portion 172 is formed in a cylindrical shape. The inner wall portion 172 is provided with a first opening 173 (173A to 173C). The first opening 173 has a size that allows the claw portion 161 of the compression portion 160 to pass through. The inner wall portion 172 is arranged so as to be housed inside the upper portion 175B formed in a cylindrical shape on the pull-out direction 191B side of the second rotating portion 175. In particular, the inner wall portion 172 is arranged so that the position of the first opening 173 coincides with the position of the second opening 176 provided in the upper portion 175B of the second rotating portion 175. The space inside the inner wall portion 172 corresponds to the internal space 141 of the holding portion 140.

The first rotating portion 174 is a member that can rotate in the rotation direction 192. The first rotating portion 174 is formed in a cylindrical shape. The first rotating portion 174 is arranged so as to cover the outer periphery of the upper portion 175B of the second rotating portion 175. The inner wall surface 179 of the first rotating portion 174 is formed so that the height in the compression direction 190 changes along the rotation direction 192.

The second rotating portion 175 is a member that can rotate in the rotation direction 192. The second rotating portion 175 includes an upper portion 175B which is a portion on the pull-out direction 191B side and a lower portion 175A which is a portion on the insertion direction 191A side. The upper portion 175B and the lower portion 175A are each formed in a cylindrical shape. The cross-sectional outer diameter of the upper portion 175B is smaller than the cross-sectional outer diameter of the lower portion 175A. In particular, the cross-sectional outer diameter of the upper portion 175B is smaller than the cross-sectional inner diameter of the first rotating portion 174. Then, the second rotating portion 175 is arranged so that the upper portion 175B is housed inside the first rotating portion 174. On the other hand, the cross-sectional outer diameter of the lower portion 175A is typically configured to be the same as or substantially the same as the cross-sectional outer diameter of the first rotating portion 174. As a result, the step at the boundary between the outer circumference of the lower portion 175A and the outer circumference of the first rotating portion 174 is minimized. The upper portion 175B is provided with a second opening 176 (176A to 176C). The second opening 176 has a size that allows the claw portion 161 of the compression portion 160 to pass through.

The first rotating portion 174 and the second rotating portion 175 rotate in opposite directions to each other. Then, as the first rotating portion 174 and the second rotating portion 175 rotate, the compression portion 160 compresses and releases the stick-type base material 150. Hereinafter, it is assumed that the second rotating portion 175 is fixed and the first rotating portion 174 is rotated in the right rotation direction 192A or the left rotation direction 192B. The rotation of the first rotating unit 174 and the second rotating unit 175 may be manually performed by the user. Further, the rotation of the first rotating portion 174 and the second rotating portion 175 may be automatically performed by a mechanism such as a motor (not shown).

The first bottom portion 177 and the second bottom portion 178 are members that form the ends of the suction device 100 in the insertion direction 191A. The first bottom portion 177 and the second bottom portion 178 are in a state where the tip of the heating portion 121 protrudes from the first bottom portion 177 and the heating portion 121 is sandwiched between the first bottom portion 177 and the second bottom portion 178. , Fitted. Then, the first bottom portion 177 and the second bottom portion 178 insert the tip of the heating portion 121 protruding from the first bottom portion 177 into the internal space of the inner wall portion 172 arranged inside the upper portion 175B of the second rotating portion 175. In this way, it is fitted to the lower portion 175A of the second rotating portion 175.

The heating portion 121 is arranged so that the tip protrudes into the internal space of the inner wall portion 172. When the stick-type base material 150 is inserted into the internal space of the inner wall portion 172, the tip of the heating portion 121 is inserted into the stick-type base material 150 so as to pierce the base material portion 151 of the stick-type base material 150. Will be done. The heating unit 121 can heat the aerosol source contained in the surrounding base material element by generating heat.

The suction device 100 according to this configuration has three compression units 160 of compression units 160A to 160C as compression units 160. Then, the three compression units 160 compress the stick-type base material 150 from three different directions. With such a configuration, all of the plurality of compression portions 160 can compress the stick-type base material 150 regardless of the position and orientation of the stick-type base material 150 in the internal space 141 of the holding portion 140.

The compression portion 160 includes a claw portion 161 and a base portion 162. The claw portion 161 is configured as a plate-shaped member extending in the insertion / removal direction 191 and the compression direction 190. The base 162 is configured as a rod-shaped member extending in the insertion / removal direction 191. The compression portion 160 is arranged so that the base portion 162 is in contact with the inner wall surface 179 of the first rotating portion 174, and the position of the claw portion 161 coincides with the positions of the first opening 173 and the second opening 176. NS. A mechanism such as a spring is provided between the compression unit 160 and the second rotation unit 175 to generate a repulsive force with respect to the compression unit 160 in the direction opposite to the compression direction 190.

The compression unit 160 compresses the stick-type base material 150 by moving in the compression direction 190. Specifically, when the first rotating portion 174 rotates, the base portion 162 slides on the inner wall surface 179 of the first rotating portion 174. As a result, the position of the compression portion 160 in the compression direction 190 changes according to the change in the height of the inner wall surface 179 in the compression direction 190.

Here, the inner wall surface 179 of the first rotating portion 174 is configured such that the height in the compression direction 190 is higher in the right rotation direction 192A and lower in the left rotation direction 192B with respect to each of the plurality of compression portions 160. .. For example, the inner wall surface 179A to which the base portion 162A of the compression portion 160A contacts is configured so that the height in the compression direction 190 is as high as 192A in the right rotation direction and as low as 192B in the left rotation direction.

Therefore, when the first rotating portion 174 rotates in the left rotation direction 192B, the height of the inner wall surface 179 at the position where the base portion 162 contacts gradually increases, so that the compression portion 160 moves in the compression direction 190. For example, when the first rotating portion 174 rotates in the counterclockwise rotation direction 192B, the height of the inner wall surface 179A at the position where the base portion 162A of the compression portion 160A contacts gradually increases, so that the compression portion 160A moves in the compression direction 190A. .. As a result, as shown in FIG. 5, the claw portion 161 presses the stick-type base material 150 through the first opening 173 and the second opening 176. For example, the claw portion 161A of the compression portion 160A presses the stick-type base material 150 through the first opening 173A and the second opening 176A.

On the other hand, when the first rotating portion 174 rotates in the clockwise rotation direction 192A, the height of the inner wall surface 179 at the position where the base portion 162 contacts gradually decreases. Therefore, the compression unit 160 moves in the direction opposite to the compression direction 190 by receiving a repulsive force generated by a mechanism such as a spring provided between the compression unit 160 and the second rotation unit 175. For example, when the first rotating portion 174 rotates in the clockwise rotation direction 192A, the height of the inner wall surface 179A at the position where the base portion 162A of the compression portion 160A contacts is gradually lowered, so that the compression portion 160A is in the direction opposite to the compression direction 190A. Move to. As a result, as shown in FIG. 4, the claw portion 161 separates from the stick-type base material 150 through the first opening 173 and the second opening 176. For example, the claw portion 161A of the compression portion 160A separates from the stick-type base material 150 through the first opening 173A and the second opening 176A.

(2) Tip Shape of the Compression Unit 160 FIG. 6 is a cross-sectional view showing an example of a cross section orthogonal to the insertion / extraction direction 191 of the compression unit 160 according to the present embodiment. As shown in FIG. 6, the cross-sectional shape of the tip surface of the compression portion 160 (more accurately, the claw portion 161) in the compression direction 190 may be convex. In particular, the cross-sectional shape of the tip surface of the compression portion 160 (more accurately, the claw portion 161) in the compression direction 190 may be a convex arc shape. Width _{W C} of the arc of the front end surface of the claw portion 161, the radius _{R C} of the arc of the front end surface of the claw portion 161, the compression length _{L C,} and the winding diameter _{D S} of the base portion 151, may employ any dimension be. Note that the compression length L _C, when compressed by the compression unit 160, compression unit 160 (more precisely, the claw portions 161) long front end surface of the moves from contact with the outer periphery of the base portion 151 of Is. For example, various dimensions can be set as shown in Table 1 below.

FIG. 7 is a cross-sectional view showing an example of a cross section orthogonal to the insertion / extraction direction 191 of the compression unit 160 according to the present embodiment. As shown in FIG. 7, the cross-sectional shape of the tip surface of the compression portion 160 (more accurately, the claw portion 161) in the compression direction 190 may be concave. In particular, the cross-sectional shape of the tip surface of the compression portion 160 (more accurately, the claw portion 161) in the compression direction 190 may be a concave arc shape. Width _{W C} of the arc of the front end surface of the claw portion 161, the radius _{R C} of the arc of the front end surface of the claw portion 161, the compression length _{L C,} and the winding diameter _{D S} of the base portion 151, may employ any dimension be. Both ends of the concave arc on the tip surface of the claw portion 161 may be formed in a convex arc shape. Then, any dimension can be adopted as _{the radius RH} of the arcs at both ends of the arc on the tip surface of the claw portion 161. For example, various dimensions can be set as shown in Table 2 below.

(3) Timing of compression and heating The suction device 100 according to the present embodiment starts the other based on the start of one of the heating by the heating unit 121 and the compression by the compression unit 160. As an example, the suction device 100 starts compression by the compression unit 160 based on the start of heating by the heating unit 121. In this case, the compression by the compression unit 160 is automatically performed. As another example, the suction device 100 starts preheating by the heating unit 121 based on the start of compression by the compression unit 160. In this case, the compression by the compression unit 160 may be performed manually or automatically.

If there is a gap between the heating unit 121 and the base material element, the thermal conductivity from the heating unit 121 to the entire base material portion 151 will decrease, and it will be difficult to efficiently generate an aerosol. In this regard, by performing compression and heating at the same time, the contact area between the heating portion 121 and the base material element can be improved, so that the thermal conductivity can be improved.

If there is a gap between the base material elements in the base material portion 151, the thermal conductivity from the heating portion 121 to the entire base material portion 151 is lowered, and it is difficult to efficiently generate an aerosol. In this regard, by simultaneously performing compression and heating, the density of the base material elements in the base material portion 151 can be improved, so that the thermal conductivity can be improved.

By improving the thermal conductivity, it is possible to improve the effect of raising the temperature of the base material portion 151 and shorten the preheating time. That is, it is possible to improve the quality of the user's suction experience.

Further, the suction device 100 stops the compression by the compression unit 160 when a predetermined time elapses from the start of the compression by the compression unit 160. In other words, the suction device 100 controls the compression time to a predetermined time. The compression time is the time from the start of compression by the compression unit 160 to the stop of compression. With such a configuration, as will be described in detail later with reference to the experimental results, the effect of raising the temperature of the base material portion 151 can be improved, the amount of aerosol components in the suction gas can be improved, and sticking and detachment can be reduced. can do. That is, it is possible to improve the quality of the user's suction experience.

<< 3. Suitable configuration based on experimental results >>
The present inventors conducted various experiments on compression by the compression unit 160, and found a suitable configuration of the suction device 100. First, the experimental environment common to each experiment will be described below. Then, the experimental result and the suitable configuration of the suction device 100 will be described.

The dimension of the compression unit 160 is one of the above-mentioned dimensions C1 to C4. The effective pressure by the compression unit 160 is estimated to be 25 N, and the pressure is 0.4 Mpa. The material of the compression unit 160 is SSUS (Stainless Steel) material or PEEK (Polyether Ether Ketone) material.

The heating unit 121 is a columnar ceramic heater with a diameter of 2.5 mm. The temperature of the heating unit 121 during heating is 350 ° C. The heating unit 121 rises from a state of about 25 ° C to 350 ° C. When the stick-type base material 150 is not inserted into the suction device 100, the temperature of the heating unit 121 instantly rises to 350 ° C. On the other hand, when the stick-type base material 150 is inserted into the suction device 100, it takes about 10 seconds for the temperature of the heating unit 121 to rise to 350 ° C. The temperature of the base material portion 151 is detected by a temperature sensor inserted into the base material portion 151.

A puff with a flow rate of 55 cc / 2 seconds is simulated by a machine. Puffing is done at 30 second intervals. The aerosol source is glycerin. The amount of the aerosol component in the aspirated gas (hereinafter, also referred to as the aspirated gas) is analyzed by gas chromatography.

The experimental results described below are the average of the experimental results conducted three times in the same environment and method.

-Experiment on tearing The present inventors conducted an experiment to investigate the occurrence of tearing when compression was performed by the compression unit 160. Tearing is a phenomenon in which the wrapping paper of the stick-type base material 150 is torn.

The experimental method and experimental environment will be explained. The present inventors investigated the occurrence of tearing in the suction device 100 adopting the various dimensions shown in Tables 1 and 2 when the suction device 100 was released 15 seconds after the start of compression by the compression unit 160. The temperature is 22 ° C. Humidity is 50%. Table 3 below shows the experimental results.

_“DS ′” in Table 3 above is the winding diameter of the base material portion 151 after compression.

According to Table 3 above, in the case of dimensions C1 and C3, the stick-type base material 150 has imprints but is not torn. On the other hand, in the case of dimensions C2 and C4, the stick type base material 150 was torn. The tear occurred at a position where the hardness changed in the longitudinal direction of the stick-type base material 150. The difference in hardness is caused by the difference in contents.

According to the above experimental results, when the winding diameter of the stick-type substrate 150 is 7.1 mm, the compression length _{L C} is preferably within 1 mm. If the compressed length _{L C} is greater than 1 mm, because the tear occurs. Further, according to the above experimental results, the compression length _{L C,} it is more preferable is within 0.5 mm. If the compression length _{L C} is within 0.5 mm, because the break does not occur. Incidentally, depending on the winding diameter D _S of the stick-type substrate 150, the compression length L _C may be changed as appropriate.

-Experiment on material The present inventors conducted an experiment to investigate the relationship between the material of the compression unit 160 and the temperature rising effect.

The experimental method and experimental environment will be explained. The present inventors confirmed the time-series transition of the temperature of the base material portion 151 after the preheating by the heating portion 121 was started while switching the material of the compression portion 160 and the presence or absence of compression. The temperature is 22 ° C. Humidity is 60%.

FIG. 8 is a graph showing the experimental results of the suction device 100 according to the present embodiment. The horizontal axis of the graph 200 is the preheating time. The preheating time is the elapsed time from the start of preheating. The vertical axis of the graph 200 is the temperature of the re-outer shell (that is, rolling paper) of the heated portion of the base material portion 151. Graph 200 includes lines 201 to 203. Line 201 shows the experimental results when compression is not performed by the compression unit 160 made of SUS (stainless steel) material. Line 202 shows the experimental results when compression is performed by the compression unit 160 formed of SUS (stainless steel) material. Line 203 shows the experimental results when compression is performed by the compression unit 160 formed of PEEK material.

Comparing the wire 201 and the wire 202, it can be seen that the temperature of the base material portion 151 at the same time in the period 204 from 0 second to about 18 seconds after the start of the preheating is higher in the wire 202 than in the wire 201. That is, in the period 204, the effect of raising the temperature of the base material portion 151 can be obtained by performing compression by the compression portion 160 formed of the SUS (stainless steel) material.

Comparing the wire 201 and the wire 203, it can be seen that the temperature of the base material portion 151 at the same time in the period 205 from 0 second to about 70 seconds after the start of the preheating is higher in the wire 203 than in the wire 201. That is, in the period 205, the effect of raising the temperature of the base material portion 151 can be obtained by performing the compression by the compression portion 160 formed of the PEEK material.

As shown in the above-mentioned experimental results, it is desirable that the compression portion 160 is formed of a heat-resistant material. An example of a heat-resistant material is a metal material such as SUS (stainless steel) material. Another example of the heat-resistant material is a non-metallic material such as PEEK material. With such a configuration, the effect of raising the temperature of the base material portion 151 can be obtained.

Comparing the wire 202 and the wire 203, it can be seen that the temperature of the base material portion 151 at the same time is generally higher in the wire 203 than in the wire 202. That is, when the material of the compression portion 160 is PEEK material, a higher temperature raising effect can be obtained than when it is made of SUS (stainless steel) material. Such a difference is considered to be due to thermal conductivity. The thermal conductivity of the SUS (stainless steel) material is 236 Wm ^-1 ° C ^-1 . The thermal conductivity of PEEK material is 0.25 Wm ^-1 ° C ^-1 .

-Experiment to confirm the heating effect by compression The present inventors conducted an experiment to investigate the relationship between the compression time and the heating effect.

The experimental method and experimental environment will be explained. The present inventors have switched the presence / absence of compression by the compression unit 160, the compression time, the timing of the start of compression, and the shape of the tip of the compression unit 160, and the temperature of the base material portion 151 after the preheating by the heating unit 121 is started. We confirmed the time-series transition. The temperature is 22 ° C. Humidity is 60%. The compression portion 160 is made of a SUS (stainless steel) material.

FIG. 9 is a graph showing the experimental results of the suction device 100 according to the present embodiment. The horizontal axis of the graph 210 is the elapsed time from the start of preheating. The vertical axis of the graph 210 is the temperature of the re-outer shell (that is, rolling paper) of the heated portion of the base material portion 151. Graph 210 includes lines 211 to 217. Line 211 shows the experimental result when the compression unit 160 does not perform compression. Line 212 shows the experimental result when compression is constantly performed by the compression unit 160 having a convex tip shape. Line 213 shows the experimental results when compression by the compression unit 160 having a convex tip shape is performed for 5 seconds from the start of preheating. Line 214 shows the experimental results when compression by the compression unit 160 having a convex tip shape is performed for 10 seconds from the start of preheating. Line 215 shows the experimental results when compression by the compression unit 160 having a convex tip shape is performed for 20 seconds from the start of preheating. Line 216 shows the experimental results when compression by the compression unit 160 having a concave tip shape is performed for 5 seconds from the start of preheating. Line 217 shows the experimental results when compression by the compression unit 160 having a convex tip shape is performed for 5 seconds before the start of preheating.

Comparing the wire 211 and the wire 217, it can be seen that the temperature of the base material portion 151 at the same time is generally higher in the wire 211 than in the wire 217. On the other hand, when the wire 211 and the wire 212 to the wire 216 are compared, it can be seen that the temperature of the base material portion 151 at the same time is generally higher in the wire 212 to the wire 216 than in the wire 211. That is, by performing the compression by the compression unit 160 not before the start of the preheating but after the start of the preheating (for example, at the same time as the start of the preheating), the effect of raising the temperature of the base material portion 151 can be obtained.

According to the above experimental results, it is desirable that the compression by the compression unit 160 is performed during the preheating. Therefore, the suction device 100 matches the start timing of heating by the heating unit 121 with the start timing of compression by the compression unit 160. That is, the suction device 100 starts preheating by the heating unit 121 and compression by the compression unit 160 at the same time. With such a configuration, it is possible to obtain a suitable temperature raising effect. Of course, in the suction device 100, the start timing of heating by the heating unit 121 and the start timing of compression by the compression unit 160 do not necessarily have to be the same, and may be substantially the same. The "substantial agreement" here means that the difference between the heating start timing and the compression start timing is, for example, within 1 second. With such a configuration, it is possible to obtain the same temperature raising effect.

Comparing the wire 211 and the wire 212 to the wire 216, it can be seen that the temperature of the base material portion 151 at the same time is generally higher in the wire 212 to the wire 216 than in the wire 211. However, in the period immediately after the start of preheating (for example, the period 218 up to 22 seconds after the start of preheating), the temperature difference is relatively small. On the other hand, in the period 219 after 40 seconds after the start of preheating, the temperature difference is relatively large. That is, the effect of raising the temperature can be obtained not only during compression but also for a long period of time after opening.

However, when comparing the wire 211 and the wire 212, the temperature of the base material portion 151 at the same time is higher in the wire 212 than in the wire 211 until 70 seconds after the start of the preheating, but after 70 after the start of the preheating. Line 211 is higher than line 212. That is, in the case of constant compression, it is difficult to obtain a temperature raising effect after 70 seconds.

Further, when the wire 212 and the wire 213 to the wire 216 are compared, it can be seen that the temperature of the base material portion 151 at the same time is generally higher in the wire 213 to the wire 216 than in the wire 212. That is, a higher temperature rising effect can be obtained by releasing the compression at an appropriate timing after the compression, rather than constantly compressing the compression.

Therefore, the suction device 100 stops the compression by the compression unit 160 when a predetermined time has elapsed from the start of the compression by the compression unit 160. As an example, of the lines 213 to 215, the one having the highest temperature of the base material portion 151 at the same time is the wire 214. Therefore, when the tip shape of the compression portion 160 is convex, the compression time is set to about 10 seconds. It is desirable to do. As another example, when the tip shape of the compression portion 160 is concave, it is desirable that the compression time is about 5 seconds. With such a configuration, the effect of raising the temperature of the base material portion 151 can be obtained.

-Experiment on the amount of aerosol component in the suction gas in the initial puff The present inventors conducted an experiment to investigate the relationship between the compression time and the amount of the aerosol component in the suction gas in the initial puff. The initial puff is the first puff.

The experimental method and experimental environment will be explained. The present inventors confirmed the amount of aerosol components in the suction gas in the initial puff while switching the presence / absence of compression by the compression unit 160, the compression time, and the tip shape of the compression unit 160. The temperature is 22 ° C. Humidity is 60%.

FIG. 10 is a graph showing the experimental results of the suction device 100 according to the present embodiment. The horizontal axis of the graph 220 is the preheating time. The vertical axis of the graph 220 is the amount of the aerosol component in the suction gas in the initial puff. Graph 220 includes lines 221 to 224. Line 221 shows the experimental result when the compression unit 160 does not perform compression. Line 222 shows the experimental result when compression by the compression unit 160 having a convex tip shape is performed for 5 seconds from the start of preheating. Line 223 shows the experimental results when compression by the compression unit 160 having a convex tip shape is performed for 10 seconds from the start of preheating. The line (point) 224 shows the experimental result when compression by the compression portion 160 having a concave tip shape is performed for 5 seconds from the start of preheating.

Comparing the wire 221 and the wire 223, it can be seen that when the preheating is performed for 20 seconds or more, the amount of the aerosol component in the suction gas is higher in the wire 223 than in the wire 221. When the preheating is performed for 20 seconds or more, the amount of the aerosol component in the suction gas can be increased by performing the compression by the compression unit 160 having a convex tip shape for 10 seconds from the start of the preheating.

Comparing the wire 221 and the wire 224, it can be seen that when the preheating is performed for 15 seconds, the amount of the aerosol component in the suction gas is higher in the wire 224 than in the wire 221. That is, when the preheating is performed for 15 seconds, the amount of the aerosol component in the suction gas can be increased by performing the compression by the compression unit 160 having a concave tip shape for 5 seconds from the start of the preheating.

-Experiment on the transition of the aerosol component content in the suction gas The present inventors conducted an experiment to investigate the relationship between the compression time and the transition of the aerosol component content in the suction gas. The change in the amount of the aerosol component in the suction gas is the change in the amount of the aerosol component in the suction gas for each puff performed a plurality of times.

The experimental method and experimental environment will be explained. The present inventors confirmed the transition of the amount of aerosol components in the suction gas for each puff while switching the presence / absence of compression by the compression unit 160, the compression time, the tip shape of the compression unit 160, and the start timing of the puff. The temperature is 22 ° C. Humidity is 60%.

FIG. 11 is a graph showing the experimental results of the suction device 100 according to the present embodiment. The horizontal axis of the graph 230 is the number of puffs. The vertical axis of the graph 230 is the amount of the aerosol component in the suction gas for each puff. Graph 230 includes lines 231 to 234. Line 231 shows the experimental results when the puff was started 15 seconds after the start of preheating without compression by the compression unit 160. Line 232 shows the experimental results when the puff was started 20 seconds after the start of preheating without compression by the compression unit 160. Line 233 is an experimental result when compression by the compression portion 160 having a convex tip shape is performed for 10 seconds from the start of preheating, and puffing is started 20 seconds after the start of preheating (that is, 10 seconds after the stop of compression). Is shown. Line 234 shows the experimental results when compression by the compression portion 160 having a concave tip shape is performed for 5 seconds from the start of preheating, and the puff is started 15 seconds after the start of preheating (that is, 10 seconds after the stop of compression). show.

Comparing the wire 231 and the wire 232 with the wire 233, it can be seen that the amount of the aerosol component in the suction gas at the same number of puffs is generally higher in the wire 233 than in the wire 231 and the wire 232. That is, by performing compression by the compression unit 160 having a convex tip shape, it is possible to increase the amount of the aerosol component in the suction gas in the puffs a plurality of times.

Comparing the wire 231 and the wire 232 with the wire 234, it can be seen that the amount of the aerosol component in the suction gas at the same number of puffs is generally higher in the wire 234 than in the wire 231 and the wire 232. That is, by performing compression by the compression unit 160 having a concave tip shape, it is possible to increase the amount of the aerosol component in the suction gas in the puffs a plurality of times.

-Experiments on sticking and sticking The present inventors conducted an experiment to investigate the occurrence of sticking and sticking when compression was performed by the compression unit 160.

The removal means that the base material element comes off from the stick-type base material 150 pulled out from the suction device 100. When peeling occurs, the base material elements fall off from the stick-type base material 150 after use and are scattered around, so it is desirable that the amount of pulling out is small.

Fixation means that the base material element is fixed to the heating portion 121. When sticking occurs, the user is required to perform cleaning to remove the stuck base material element from the suction device 100. Further, when sticking occurs, the amount of the aerosol component in the suction gas decreases. Further, when sticking occurs, a burning odor is generated. From these circumstances, it is desirable that the amount of sticking is small.

The experimental method and experimental environment will be explained. The present inventors confirmed the state of the stick-type base material 150 after use while switching the compression time by the compression unit 160 and the tip shape of the compression unit 160. The present inventors started compression by the compression unit 160 at the same time as preheating by the heating unit 121, stopped heating 15 seconds after the compression stopped and became an open state, and sucked the stick-type base material 150 into a suction device. It was pulled out from 100, and the state of the stick-type base material 150 was confirmed. The material of the compression unit 160 is PEEK material. The dimension of the compression unit 160 is dimension C1 or dimension C3. The temperature is 22 ° C. Humidity is 50%. Table 4 below shows the experimental results.

The omission level is an index that quantifies the number of omissions. The omission level "1" indicates that no omission has occurred. The omission level "2" indicates that a small amount of omission has occurred. The omission level "3" indicates that a large amount of omission has occurred.

The sticking level is an index that quantifies the amount of sticking. A sticking level of "1" indicates that no sticking has occurred. A sticking level "2" indicates that a small amount of sticking has occurred. The fixation level "3" indicates that a large amount of fixation has occurred.

FIG. 12 is a graph of Table 4 above. The horizontal axis of the graph 240 is the compression time. The vertical axis of the graph 240 is the sticking level and the pull-out level. Graph 240 includes lines 241 and 242. Line 241 shows the experimental result when compression is performed by the compression unit 160 having a convex tip shape. That is, the line 241 is a graph of the experimental results when the dimension C1 (convex shape) is adopted as the tip shape in Table 4 above. Line 242 shows the experimental result when compression is performed by the compression unit 160 having a concave tip shape. That is, the line 242 is a graph of the experimental results when the dimension C3 (concave shape) is adopted as the tip shape in Table 4 above.

With reference to line 241 it can be seen that when the compression time is 70 seconds or more when compression is performed by the compression unit 160 having a convex tip shape, a large amount of disconnection and sticking occurs. Therefore, it is desirable that the compression time is 70 seconds or less. According to such a configuration, it is possible to prevent the occurrence of excessive removal and sticking.

With reference to line 241 it can be seen that when the compression time is 60 seconds or less when compression is performed by the compression unit 160 having a convex tip shape, disconnection and sticking do not occur. Therefore, it is desirable that the compression time is 60 seconds or less. According to such a configuration, it is possible to prevent the occurrence of disconnection and sticking.

With reference to line 242, it can be seen that when the compression time is 15 seconds or more when compression is performed by the compression unit 160 having a concave tip shape, a large amount of disconnection and sticking occurs. Therefore, it is desirable that the compression time is 15 seconds or less. According to such a configuration, it is possible to prevent the occurrence of excessive removal and sticking.

With reference to line 242, it can be seen that when the compression time is 10 seconds or less when compression is performed by the compression unit 160 having a concave tip shape, a small amount of omission and sticking occur. Therefore, it is desirable that the compression time is 10 seconds or less. According to such a configuration, it is possible to keep or prevent a small amount of disconnection and sticking.

Comparing the wire 241 and the wire 242, it can be seen that when the tip shape of the compression portion 160 is convex, there is less loss and sticking in the same compression time than when the tip shape of the compression portion 160 is concave. Therefore, it is desirable that the tip shape of the compression portion 160 is convex. According to such a configuration, it is possible to keep or prevent a small amount of disconnection and sticking.

<< 4. Process flow >>
FIG. 13 is a diagram showing an example of a flow of processing executed in the suction device 100 according to the present embodiment.

As shown in FIG. 13, first, the suction device 100 determines whether or not a user operation instructing the start of preheating is detected (step S102). If it is determined that the user operation instructing the start of preheating has not been detected (step S102: NO), the process returns to step S102 again. When it is determined that the user operation instructing the start of preheating is detected (step S102: NO), the suction device 100 starts preheating by the heating unit 121 and starts compression by the compression unit 160 (step S104). ).

Next, the suction device 100 determines whether or not the first predetermined time has elapsed since the start of preheating and compression (step S106). If it is determined that the first predetermined time has not elapsed (step S106: NO), the process returns to step S106 again. When it is determined that the first predetermined time has elapsed (step S106: YES), the suction device 100 stops the compression by the compression unit 160 (step S108). The first predetermined time can be arbitrarily set based on the experimental results regarding the compression time.

Next, the suction device 100 determines whether or not a second predetermined time has elapsed since the start of preheating and compression (step S110). If it is determined that the second predetermined time has not elapsed (step S110: NO), the process returns to step S110 again. When it is determined that the second predetermined time has elapsed (step S110: YES), the suction device 100 stops heating by the heating unit 121 (step S112). As an example, the second predetermined time can be arbitrarily set as a value equal to or greater than the first predetermined time.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the field of technology to which the present invention belongs can come up with various modifications or modifications within the scope of the technical ideas described in the claims. It is naturally understood that these also belong to the technical scope of the present invention.

For example, in the above embodiment, a convex arc shape and a concave arc shape are given as examples of the tip shape of the claw portion 161, but the present invention is not limited to such an example. For example, the tip shape of the claw portion 161 may be a flat surface or a sphere. Further, the dimensions of the claw portion 161 are not limited to the examples shown in Tables 1 and 2 above. For example, the various dimensions shown in Tables 1 and 2 may be scaled while fixing the ratio.

For example, in the above, the experimental result in which the temperature of the heating unit 121 during heating is set to 350 ° C. has been described, but the temperature of the heating unit 121 during heating is not limited to 350 ° C. As an example, the temperature of the heating unit 121 during heating may be 310 ° C. Of course, the temperature of the heating unit 121 during heating may be any other temperature such as 300 ° C. or 320 ° C., or may change in time series according to the elapsed time from the start of heating.

For example, in the above embodiment, the suction device 100 has described an example in which the compression by the compression unit 160 is stopped when a predetermined time has elapsed from the start of the compression by the compression unit 160, but the present invention is not limited to such an example. .. For example, the suction device 100 may control the timing at which the compression by the compression unit 160 is stopped based on the number of times the user sucks the aerosol. Specifically, the suction device 100 continues compression by the compression unit 160 until the number of puffs reaches a predetermined number of times, and stops compression by the compression unit 160 when the number of puffs reaches a predetermined number of times, and is a stick-type base material. You may open 150. As described above with reference to the experimental results, a higher temperature rising effect can be obtained by releasing the compression at an appropriate timing after compression rather than constantly compressing the compression. One of the factors is considered to be that opening the stick-type base material 150 reduces heat conduction to the claw portion 161 and raises the temperature of the stick-type base material 150. On the other hand, as the number of puffs increases, the aerosol source contained in the stick-type base material 150 is consumed and decreases, and it is considered that the amount of aerosol produced decreases. In this regard, according to this configuration, the decrease in the amount of aerosol produced due to the increase in the number of puffs is offset by the increase in the amount of aerosol produced due to the temperature rise due to the opening of the stick-type base material 150, and the aerosol in the suction gas is offset. It is possible to suppress a decrease in the amount of the component of. Therefore, it is possible to prevent the deterioration of the taste with the passage of time from the start of heating and improve the quality of the suction experience of the user.
