That is, the two air inlet holes 9 are arranged at positions symmetrical to each other with the center axis CL of the non-combustion heating type smoking article 1 as the center.
上述構成之非燃燒加熱型抽煙物品1中，若電子控制部5檢測到抽煙者對電源開關6進行導通操作，則電子控制部5對電源部2送出控制訊號，開始對加熱器4通電。其結果，發熱體41發熱而加熱香味源收容莢3之 耐熱容器31。藉此，加熱收容於耐熱容器31內之香味源32而釋出由香味源32蒸發之含有香味成分之蒸氣(以下稱為「香味蒸氣」)。藉由香味源32蒸發而生成的香味蒸氣係由香味源收容莢3中之耐熱容器31之蒸氣釋出口31c流入腔室部8，並暫時積滯於腔室部8。 In the non-combustion heating type smoking article 1 configured as described above, if the electronic control unit 5 detects that the smoker conducts the power switch 6, the electronic control unit 5 sends a control signal to the power source unit 2 and starts to energize the heater 4. As a result, the heating element 41 generates heat and heats the fragrance source containing the pod 3 Heat-resistant container 31. Thereby, the aroma source 32 contained in the heat-resistant container 31 is heated, and the aroma component-containing vapor (hereinafter referred to as "fragrance vapor") evaporated from the aroma source 32 is released. The fragrance vapor generated by the evaporation of the fragrance source 32 flows into the chamber portion 8 through the vapor release port 31c of the heat-resistant container 31 in the fragrance source storage pod 3, and temporarily accumulates in the chamber portion 8.
如上述，在腔室部8內積滯有香味蒸氣之狀態下，抽煙者叼住吸嘴20並吸嘗時，通過連通腔室部8內外之各空氣進入孔9使外部空氣進入腔室部8。如此，吸嘗時通過各空氣進入孔9流入腔室部8之空氣係與滯留於腔室部8之香味蒸氣混合而形成氣溶膠，該氣溶膠輸送至吸嘴20之吸口孔200，通過此吸口孔200供給至抽煙者口腔內。 As described above, when the scented vapor is accumulated in the chamber portion 8, when the smoker grabs the mouthpiece 20 and sucks, the external air enters the chamber portion through the air inlet holes 9 communicating with the inside and outside of the chamber portion 8. 8. In this way, the air flowing into the chamber portion 8 through the air inlet holes 9 during the inhalation is mixed with the scent vapors retained in the chamber portion 8 to form an aerosol, and the aerosol is transported to the suction port 200 of the suction nozzle 20 through which The suction port 200 is supplied into the mouth of a smoker.
根據本實施形態之非燃燒加熱型抽煙物品1，由於具備：腔室部8，係與香味源收容莢3中的蒸氣釋出口31c及吸嘴20之吸口孔200連通，用以暫時積滯藉由香味源32蒸發而生成之香味蒸氣；及空氣進入孔9，係連通腔室部8內外，且構成為香味源收容莢3之蒸氣釋出口31c僅對腔室部8開放，因此，通過空氣進入孔9進入腔室部8內之空氣可不通過香味源收容莢3之耐熱容器31內而與積滯於腔室部8之香味蒸氣混合，而往吸嘴20之吸口孔200輸送。亦即，由於採用以下構造：使由空氣進入孔9流入腔室部8內之空氣(以下亦稱為「進入空氣」)不通過以發熱體41加熱成非常高溫之耐熱容器31內(以下稱為「加熱部非通氣構造」)，故可抑制由空氣進入孔9流入腔 室部8內之空氣流經高溫而使溫度過度上升。藉此，可抑制往口腔內輸送之煙溫度過度提高。又，在此所述之煙中係混有氣溶膠及蒸氣，故本說明書中的「煙」可視作為混有「氣溶膠」及「蒸氣」之混合氣。 The non-combustion heating type smoking article 1 according to the present embodiment is provided with a chamber portion 8 which is in communication with the vapor release port 31c in the fragrance source storage pod 3 and the suction port 200 of the suction nozzle 20 for temporarily accumulating borrowing money. The fragrance vapor generated by the evaporation of the fragrance source 32; and the air inlet hole 9, which communicates with the inside and outside of the chamber portion 8, and the vapor release outlet 31c configured as the fragrance source receiving pod 3 is only opened to the chamber portion 8, and therefore passes through the air The air entering the cavity 9 into the chamber portion 8 through the entrance hole 9 may be mixed with the aroma vapor accumulated in the chamber portion 8 without passing through the heat-resistant container 31 containing the pod 3 in the fragrance source, and conveyed to the suction hole 200 of the suction nozzle 20. That is, because the following structure is adopted: The air (hereinafter also referred to as "intake air") flowing into the chamber portion 8 from the air inlet hole 9 is not heated to a very high temperature heat-resistant container 31 by the heating element 41 (hereinafter referred to as It is a "non-ventilating structure of the heating part"), so it can be prevented from flowing into the cavity through the air inlet hole 9 The air in the chamber portion 8 passes through a high temperature and the temperature rises excessively. This can prevent the temperature of the smoke delivered into the oral cavity from increasing excessively. Since the aerosol and vapor are mixed in the smoke described herein, the “smoke” in this specification can be regarded as a mixed gas mixed with “aerosol” and “steam”.
又，由於採用如上述使由空氣進入孔9進入腔室部8內之空氣不通氣於耐熱容器31內之加熱部非通氣構造，故可抑制以加熱器4之發熱體41加熱時，過度促進收容於耐熱容器31內之香味源32的蒸發。藉此，可防止香味源32中之香味成分減少速度過快，可抑制抽煙者多次抽吸(吸嘗)時，煙量、香味的濃度急速減少。由以上方式，根據本實施形態之非燃燒加熱型抽煙物品1，煙溫度(氣溶膠與蒸氣之混合氣溫度)不會過度上升，且可使每次吸嘗所輸送之香味成分量安定。 Furthermore, since the non-ventilating structure that prevents the air entering the chamber portion 8 from the air inlet 9 from ventilating the heating portion 31 in the heat-resistant container 31 is adopted as described above, it is possible to suppress excessive promotion when heated by the heating element 41 of the heater 4 Evaporation of the fragrance source 32 contained in the heat-resistant container 31. Thereby, it is possible to prevent the flavor component in the flavor source 32 from decreasing too quickly, and to suppress a rapid decrease in the amount of smoke and the concentration of flavor when a smoker smokes (sucks) multiple times. In the above manner, according to the non-combustion heating type smoking article 1 of this embodiment, the smoke temperature (the temperature of the mixed gas of aerosol and steam) does not increase excessively, and the amount of the aroma component delivered each time is stabilized.
又，根據本實施形態之非燃燒加熱型抽煙物品1，由於具有腔室部8，係具有足以將由收容於耐熱容器31內之香味源32蒸發之香味蒸氣適度積滯之容積，故即使採用由空氣進入孔9進入腔室部8內之空氣不通氣於耐熱容器31內之非通氣構造，亦可適當地促進香味源32的蒸發，充分地確保煙量。 In addition, according to the non-combustion heating type smoking article 1 of the present embodiment, since the cavity portion 8 is provided, the smoking vapor has a volume sufficient to accumulate the fragrance vapor evaporated from the fragrance source 32 contained in the heat-resistant container 31, so even if the The non-ventilated structure in which the air inlet hole 9 enters the cavity portion 8 is not ventilated in the heat-resistant container 31, and it can also appropriately promote the evaporation of the flavor source 32 and ensure the amount of smoke sufficiently.
又，本實施形態中，由電源部2對加熱器4通電時，電子控制部5係以耐熱容器31(或耐熱容器31內之環境溫度)成為150℃~250℃的範圍之方式控制電源部2。例如電子控制部5係可藉由習知的溫度反饋控制而控制由電源部2對加熱器4之通電，使耐熱容器31(或耐熱容器 31內之環境溫度)維持150℃~250℃的範圍。此時，可使用溫度感應器監測耐熱容器31中的側面31b之溫度，或耐熱容器31內之環境溫度。使耐熱容器31或耐熱容器31內之環境溫度維持在上述適當範圍內，可抑制香味源32(煙草細絲)燒焦，使香味源32適當地霧化。 In addition, in this embodiment, when the heater 4 is energized by the power supply unit 2, the electronic control unit 5 controls the power supply unit so that the heat-resistant container 31 (or the ambient temperature in the heat-resistant container 31) falls within the range of 150 ° C to 250 ° C. 2. For example, the electronic control unit 5 can control the energization of the heater 4 by the power supply unit 2 through the conventional temperature feedback control, so that the heat-resistant container 31 (or the heat-resistant container) The ambient temperature within 31) is maintained in the range of 150 ° C to 250 ° C. At this time, the temperature of the side surface 31 b in the heat-resistant container 31 or the temperature of the environment in the heat-resistant container 31 can be monitored using a temperature sensor. By maintaining the heat-resistant container 31 or the ambient temperature in the heat-resistant container 31 within the above-mentioned appropriate range, it is possible to suppress scorching of the flavor source 32 (tobacco filament) and appropriately atomize the flavor source 32.
又，本實施形態之非燃燒加熱型抽煙物品1係於腔室部8設置二個空氣進入孔9，該二個空氣進入孔9係對向配置在以非燃燒加熱型抽煙物品1之中心軸CL為中心互為點對稱之位置，亦即周方向相差180°之位置。如上述，將一組空氣進入孔9設置於以中心軸CL為中心對稱之位置，相較於空氣進入孔數為一個之情形，進入空氣會在腔室部8之橫剖面中央對沖，藉由其對沖可降低朝下方(香味源收容莢3方向)之進入空氣之線速度降低。其結果，相對於由空氣進入孔9流入腔室部8之進入空氣之全空氣量，可減少通過腔室部8進入香味源收容莢3內之空氣量的比例之空氣流入量率。 In addition, the non-combustion heating type smoking article 1 of the present embodiment is provided with two air inlet holes 9 in the chamber portion 8, and the two air inlet holes 9 are oppositely disposed on the central axis of the non-combustion heating type smoking article 1. CL is a position where the centers are point-symmetrical to each other, that is, a position where the circumferential direction differs by 180 °. As described above, a group of air inlet holes 9 is provided at a position symmetrical to the center axis CL. Compared with the case where the number of air inlet holes is one, the inlet air will be hedged at the center of the cross section of the chamber portion 8 by Its hedging can reduce the linear velocity of entering the air downward (toward the fragrance source receiving pod 3). As a result, the air inflow rate can be reduced in proportion to the total amount of air entering the chamber portion 8 through the air inlet hole 9 into the fragrance source receiving pod 3 through the chamber portion 8.
又，本實施形態之非燃燒加熱型抽煙物品1中，空氣進入孔9的數量以多數較佳。空氣進入孔9的數量越多，在抽煙者的吸嘗量假設為固定之條件下，由單一個空氣進入孔9流入腔室部8之空氣量越少，故由空氣進入孔9流入腔室部8之進入空氣之線速度越低。其結果，可使由空氣進入孔9流入腔室部8之進入空氣難以進入香味源收容莢3內。藉此，可更適當地提供煙溫度不會過度上升，且每次吸嘗所輸送之香味成分量安定之非燃燒加熱 型抽煙物品1。 In the non-combustion-heating type smoking article 1 of the present embodiment, the number of the air inlet holes 9 is preferably many. The greater the number of air inlet holes 9, the less the amount of air flowing into the chamber portion 8 from a single air inlet hole 9 under the condition that the smoker's smoking volume is assumed to be fixed, so the air inlet hole 9 flows into the chamber The lower the linear velocity of the part 8 into the air. As a result, it is possible to make it difficult for the intake air that has flowed into the chamber portion 8 through the air intake hole 9 to enter the fragrance source storage pod 3. Thereby, it is possible to provide a non-combustion heating in which the temperature of the smoke does not increase excessively and the amount of the aroma component delivered is stabilized each time it is tasted. Type smoking article 1.
又，非燃燒加熱型抽煙物品1係在檢測到抽煙者進行電源開關6的導通操作時，電子控制部5送出控制訊號至電源部2而開始對加熱器4通電，而在檢測到電源開關6的關斷操作時，電子控制部5送出控制訊號至電源部2而結束由電源部2對加熱器4之通電。上述情形中，由於電源開關6被導通操作使得通電開始條件成立，且由於電源開關6被關斷操作使得通電結束條件成立，並且，在通電開始條件成立起至通電結束條件成立為止之通電期間，恆常地持續由電源部2對加熱器4供給電力。此種恆常加熱型的非燃燒加熱型抽煙物品1中，在通電期間中，香味源收容莢3內恆常地進行香味源32之霧化，故特別有利於在香味源收容莢3生成之香味蒸氣流入腔室部8後，吸嘗暫時積滯於腔室部8之香味蒸氣。 In addition, when the non-combustion heating type smoking article 1 detects that the smoker performs a power-on operation of the power switch 6, the electronic control unit 5 sends a control signal to the power unit 2 to start energizing the heater 4, and detects the power switch 6 During the shutdown operation, the electronic control unit 5 sends a control signal to the power source unit 2 and ends the energization of the heater 4 by the power source unit 2. In the above case, the power-on start condition is established due to the power-on operation of the power switch 6, and the power-up end condition is established due to the power-off operation of the power switch 6, and during the power-on period from the time when the power-on start condition is established to when the power-up end condition is established, Power is continuously supplied to the heater 4 from the power supply unit 2. In such a constant heating type non-combustion heating type smoking article 1, during the power-on period, the fragrance source 32 is constantly atomized in the fragrance source storage pod 3, so it is particularly beneficial to generate the fragrance source storage pod 3 After the flavor vapor flows into the chamber portion 8, the flavor vapor temporarily accumulated in the chamber portion 8 is tasted.
又，本實施形態之非燃燒加熱型抽煙物品1中，加熱器4係具有加熱香味源收容莢3的側面之發熱體41，且採用不於腔室部8配置加熱器4之構造，故有可冷卻滯留於腔室部8之氣溶膠亦即香味吸氣之優點。又，非燃燒加熱型抽煙物品1中，未特別於腔室部8設置用以冷卻香味源32之蒸氣成分之冷卻構件。非燃燒加熱型抽煙物品1藉由採用上述加熱部非通氣構造而可抑制香味蒸氣的溫度過度提高，故無需於腔室部8設置冷卻構件，能夠以更低的成本製造抽煙裝置。 In the non-combustion heating type smoking article 1 of the present embodiment, the heater 4 has a heating element 41 that heats the side surface of the fragrance source accommodating pod 3, and adopts a structure in which the heater 4 is not arranged in the chamber portion 8. The advantage is that the aerosol retained in the chamber portion 8 can be cooled, that is, the fragrance is inhaled. In the non-combustion heating type smoking article 1, a cooling member for cooling the vapor component of the flavor source 32 is not particularly provided in the chamber portion 8. The non-combustion heating type smoking article 1 can suppress the excessive increase in the temperature of the fragrance vapor by adopting the non-ventilating structure of the heating portion, so that it is not necessary to provide a cooling member in the chamber portion 8 and the smoking device can be manufactured at a lower cost.
以下驗證依本實施形態之非燃燒加熱型抽煙 物品1而實現的各種效果。 The following is a verification of the non-combustion heating type smoking according to this embodiment. Various effects achieved by Article 1.
有關本實施形態之非燃燒加熱型抽煙物品1，為了驗證藉由採用進入空氣不通氣於耐熱容器31內之加熱部非通氣構造之煙溫度上升抑制效果，係與採用進入空氣通氣於耐熱容器31內之加熱部通氣構造之比較例1比較吸入時煙溫度。 Regarding the non-combustion heating type smoking article 1 of this embodiment, in order to verify the effect of suppressing the rise in smoke temperature by the non-ventilated structure of the heating section that does not ventilate the heat-resistant container 31, the heat-resistant container 31 is ventilated with the intake air Comparative Example 1 of the ventilation structure of the internal heating portion compares the smoke temperature during inhalation.

FIG. 4B is a diagram schematically showing the flow of incoming air in the device of the first embodiment. FIG. 5A is a diagram showing a schematic structure of the device of Comparative Example 1. FIG. FIG. 5B is a diagram schematically showing the flow of incoming air in the device of Comparative Example 1. FIG.
第4A圖及第4B圖所示實施例1係模仿本實施形態之非燃燒加熱型抽煙物品1之加熱部非通氣型裝置，使用未於底面形成通氣用孔之香味源收容莢3，並於吸嘴20中香味源收容莢3之上部開口端(蒸氣釋出口)31c起7mm的高度，於二處設置孔徑0.5mmφ之空氣進入孔9。實施例1中，蒸氣釋出口31c至空氣進入孔9之長度相對於蒸氣釋出口31c至吸口孔200(第1腔室部8A之上端)之長度之比率(以下稱為「空氣進入孔之開孔高度比率」)為20%。實施例1中，香味源收容莢3之上部開口端(蒸氣釋出口)31c至空氣進入孔9之流路中之腔室部8(第1腔室部8A)之容積(體積)設為0.4mL。又，實施例1中，腔室部8實質上僅由第1腔室部8A(吸嘴20之內部空間)構成，第2 腔室部8B之容積(體積)實質為零。另一方面，第5A圖及第5B圖所示比較例1係於形成為於香味源收容莢3底部形成直徑2mm之通氣用孔之加熱部通氣型裝置，且在吸嘴20中未形成空氣進入孔9之點與實施例1相異。又，實施例1及比較例1中，由香味源收容莢3之容積減去香味源(煙草細絲及氣溶膠基材之混合物)32所占體積之空洞部容積皆為0.3mL。 The first embodiment shown in Figs. 4A and 4B is a non-ventilating device of a heating portion of the non-combustion heating type smoking article 1 emulating the present embodiment, and uses a fragrance source that does not form a vent hole on the bottom surface to accommodate the pod 3, and The upper end of the open end (steam release port) 31c of the fragrance source receiving pod 3 in the suction nozzle 20 has a height of 7 mm, and an air inlet hole 9 having a diameter of 0.5 mmφ is provided at two places. In Example 1, the ratio of the length of the vapor release outlet 31c to the air inlet hole 9 to the length of the vapor release outlet 31c to the suction hole 200 (the upper end of the first chamber portion 8A) (hereinafter referred to as "the opening of the air inlet hole The hole height ratio ") is 20%. In Example 1, the volume (volume) of the open end (steam release outlet) 31c of the upper part of the fragrance source receiving pod 3 to the chamber portion 8 (the first chamber portion 8A) in the flow path of the air inlet hole 9 is set to 0.4. mL. In addition, in the first embodiment, the chamber portion 8 is substantially constituted only by the first chamber portion 8A (the internal space of the suction nozzle 20). The volume (volume) of the chamber portion 8B is substantially zero. On the other hand, Comparative Example 1 shown in FIG. 5A and FIG. 5B is a heating part ventilation type device formed to form a ventilation hole with a diameter of 2 mm at the bottom of the fragrance source receiving pod 3, and no air is formed in the nozzle 20. The point of entering the hole 9 is different from that of the first embodiment. Further, in Example 1 and Comparative Example 1, the volume of the cavity portion minus the volume occupied by the flavor source (mixture of tobacco filaments and aerosol base material) 32 from the volume of the flavor source receiving pod 3 was 0.3 mL.
第6圖係一覧表示煙溫度上升抑制效果的驗證試驗條件與香味源規格之圖。對於上述構成之實施例1及比較例1之各裝置，使用抽煙機(Borgwaldt，RM-26)進行抽煙試驗。抽煙試驗中之抽煙流量設為55mL/2秒，抽煙間隔設為30秒。抽煙試驗時各裝置之溫度控制係使用桌上型溫度控制單元(CHINO CORPORATION製，形式：SY2111-30)及K熱電偶。設置成K熱電偶接觸於香味源收容莢3內之香味源(煙草細絲)32的表面，並設定升溫曲線為以120秒使加熱器到達目標溫度域(200℃)，在到達目標溫度域後，即時測定香味源(煙草細絲)32之溫度以進行PID控制。 Fig. 6 is a graph showing the verification test conditions and flavor source specifications for the effect of suppressing smoke temperature rise. For each of the devices of Example 1 and Comparative Example 1 having the above-mentioned configuration, a smoking test was performed using a smoking machine (Borgwaldt, RM-26). The smoking flow rate in the smoking test was set to 55 mL / 2 seconds, and the smoking interval was set to 30 seconds. For the temperature control of each device during the smoking test, a desktop temperature control unit (manufactured by Chino Corporation, form: SY2111-30) and a K thermocouple were used. Set the K thermocouple to contact the surface of the fragrance source (tobacco filament) 32 in the fragrance source receiving pod 3, and set the temperature rise curve to make the heater reach the target temperature range (200 ° C) in 120 seconds, and reach the target temperature range Thereafter, the temperature of the flavor source (tobacco filament) 32 was measured immediately for PID control.
又，抽煙試驗時，於實施例1及比較例1之各裝置連接矽管，並將熱電偶***自吸嘴20前端30mm之位置，測定溫度變遷，藉此測定以抽煙機吸引之煙(含有氣溶膠及蒸氣之混合氣)之溫度。第7圖係表示比較例1之煙溫度變遷之測定結果之圖。第8圖係表示實施例1之煙溫度變遷之測定結果之圖。採用加熱部通氣構造之比較例1 中，第一次抽吸之煙溫度到達100℃，第五次抽吸以後約固定在60℃。另一方面，採用加熱部非通氣構造之實施例1中，第一次抽吸之最高溫度為50℃以下，第五次抽吸以後亦安定地維持在30℃附近。由以上可確認相較於採用加熱部通氣構造之比較例1，採用加熱部非通氣構造之實施例1可抑制煙溫度上升。又，根據實施例1，可確認不另外設置用以冷卻煙之煙冷卻機構亦可將抽煙時之煙溫度維持在常溫附近之溫度域。 In the smoking test, a silicon tube was connected to each of the devices of Example 1 and Comparative Example 1, and a thermocouple was inserted at a position 30 mm from the front end of the suction nozzle 20, and the temperature change was measured to measure the smoke (containing Aerosol and vapor mixture). FIG. 7 is a graph showing measurement results of smoke temperature change in Comparative Example 1. FIG. FIG. 8 is a graph showing measurement results of smoke temperature change in Example 1. FIG. Comparative example 1 using a heating part ventilation structure During the first puff, the temperature reached 100 ° C, and after the fifth puff, it was fixed at about 60 ° C. On the other hand, in Example 1 using the non-ventilating structure of the heating section, the maximum temperature of the first suction was 50 ° C. or lower, and it was stably maintained around 30 ° C. after the fifth suction. From the above, it can be confirmed that, compared with Comparative Example 1 using a ventilation structure of a heating portion, Example 1 using a non-ventilating structure of a heating portion can suppress a rise in smoke temperature. In addition, according to the embodiment 1, it can be confirmed that the smoke temperature at the time of smoking can be maintained in a temperature range near the normal temperature without separately providing a smoke cooling mechanism for cooling the smoke.
進行上述抽煙試驗時，分別在實施例1及比較例1中，測定以抽煙機吸引之氣溶膠及蒸氣所含的全粒子狀物質(TPM：total particulate matter)的量。第9圖係表示對實施例1及比較例1的抽煙試驗時，以抽煙機吸引之氣溶膠及蒸氣所含的全粒子狀物質的量之圖。縱軸表示全粒子狀物質(TPM)的量，橫軸表示抽吸次數。 When the above-mentioned smoking test was performed, the amount of total particulate matter (TPM: total particulate matter) contained in the aerosol and vapor sucked by the smoking machine was measured in Example 1 and Comparative Example 1, respectively. FIG. 9 is a graph showing the amount of all particulate matter contained in aerosols and vapors sucked by the smoking machine in the smoking test of Example 1 and Comparative Example 1. FIG. The vertical axis indicates the amount of total particulate matter (TPM), and the horizontal axis indicates the number of suctions.
又，全粒子狀物質的量之測定係使用抽煙機來實施。在特定抽煙條件(抽煙容量為55mL/2秒，抽煙間隔為30秒)下，將三十次抽吸量以間隔二次抽吸捕集於劍橋過濾器(cambridge filter)(CF)，將附著於劍橋過濾器之氣溶膠狀物質之重量增加份秤重，藉此將全粒子狀物質的量定量。有關於初期抽吸(約至十次抽吸為止)，相較於採用加熱部非通氣構造之實施例1，採用加熱部通氣構造之比較例1相對地有全粒子狀物質的量較多之傾向，另一方面， 在第十次抽吸以後，其傾向相反，可確認相較於比較例1，實施例1有全粒子狀物質的量較多之傾向。 The measurement of the amount of the whole particulate matter was performed using a smoking machine. Under specific smoking conditions (the smoking volume is 55mL / 2 seconds and the smoking interval is 30 seconds), the thirty suction volumes are captured at a second suction interval in a Cambridge filter (CF), and will adhere to The weight of the aerosol-like substance in the Cambridge filter is increased by weight, thereby quantifying the amount of the whole particulate matter. With regard to the initial suction (about ten suctions), compared with Example 1 using the non-ventilating structure of the heating portion, Comparative Example 1 using the venting structure of the heating portion has a relatively large amount of all particulate matter. Tendency, on the other hand, After the tenth suction, the tendency was reversed, and it was confirmed that Example 1 tended to have a larger amount of all particulate matter than Comparative Example 1.
有關於採用加熱部通氣構造之比較例1，尤其在富含氣溶膠溶液之抽煙初期中，在以抽煙機吸引之2秒間，由於進入空氣通過以加熱器4加熱之香味源表面，故促進香味成分之蒸發。對此，在採用加熱部非通氣構造之實施例1中，進入空氣不通過以加熱器4加熱之香味源32表面，故以抽煙機吸引時，主要吸引滯留於腔室部之蒸氣。其結果，不會像採用加熱部通氣構造之比較例1般過度地促進香味源32之蒸發，香味源32中的香味成分之減少速度適當地變小。亦即，相對於採用加熱部通氣構造之比較例1，採用加熱部非通氣構造之實施例1可安定地輸送香味成分。 As for Comparative Example 1 using the ventilation structure of the heating section, particularly in the initial stage of smoking with an aerosol-rich solution, inhalation of the air by the hood through the surface of the scent source heated by the heater 4 during 2 seconds of suction by the smoking machine promoted the scent. Evaporation of ingredients. On the other hand, in the first embodiment using the non-ventilating structure of the heating section, the incoming air does not pass through the surface of the fragrance source 32 heated by the heater 4, so when it is sucked by the smoking machine, the vapor trapped in the chamber section is mainly sucked. As a result, the evaporation of the flavor source 32 is not promoted excessively as in Comparative Example 1 using the heating part ventilation structure, and the reduction rate of flavor components in the flavor source 32 is appropriately reduced. That is, compared with the comparative example 1 using a heating part ventilation structure, the Example 1 using a heating part non-ventilation structure can stably convey a fragrance component.
在此，若將抽煙時的氣溶膠及蒸氣所含的全粒子狀物質(TPM)的量之減少率(以下稱為「TPM減少率」)定義為下式，則相對於採用加熱部通氣構造之比較例1中TPM減少率為0.91，採用加熱部非通氣構造之實施例1中TPM減少率為0.61。在此，TPM減少率較小係表示第一次抽吸至第十次抽吸之成分輸送量的減少較少(亦即安定)。如上述，由於加熱部非通氣構造(實施例1)之TPM減少率係較加熱部通氣構造(比較例1)小，故加熱部非通氣構造(實施例1)可安定地輸送成分。 Here, if the reduction rate of the total particulate matter (TPM) amount contained in the aerosol and the vapor at the time of smoking (hereinafter referred to as "TPM reduction rate") is defined as the following formula, then the heating section ventilation structure is adopted. In Comparative Example 1, the TPM reduction rate was 0.91, and in Example 1 using the non-ventilating structure of the heating portion, the TPM reduction rate was 0.61. Here, the smaller TPM reduction rate means that there is less reduction (ie, stability) in the amount of component delivery from the first puff to the tenth puff. As described above, since the TPM reduction rate of the non-ventilated structure of the heating portion (Example 1) is smaller than that of the ventilated structure of the heating portion (Comparative Example 1), the non-ventilated structure of the heating portion (Example 1) can stably transport components.
接著說明對實施例1變更腔室部8之容積(體積)、空氣進入孔9之開孔位置、開孔數、開孔徑等之實施例2~12。第10圖係一覧表示實施例1~12及比較例1之規格之圖。第10圖中一併表示實施例1~12及比較例1之空氣流入量率Rpod、實施例1~8及比較例1之煙溫度及TPM減少率。空氣流入量率Rpod詳細如後述。又，第10圖中的「開孔位置(mm)」是指香味源收容莢3之上部開口端(蒸氣釋出口)31c至空氣進入孔9之距離尺寸。又，第10圖中的「開孔高度比率(%)」是指「空氣進入孔之開孔高度比率」，如上述，係指蒸氣釋出口31c至空氣進入孔9之長度相對於蒸氣釋出口31c至吸口孔200(第1腔室部8A之上端)之長度之比率。又，有關於實施例1~8、11、12，係二個空氣進入孔9對向配置於以裝置中心軸為中心，於周方向相差180°之位置。另外，有關於實施例9，係四個空氣進入孔9配置於以裝置中心軸為中心，於周方向相差90°之位置。在此，實施例2~12係與實施例1同樣地採用加熱部非通氣構造。實施例2~4係相對於實施例1變更作為參數之腔室部8的容積。第11圖表示實施例2~4之裝置之概略構造。實施例1中之腔室部8之容積(第1腔室部8A與第2腔室部之容積的合計)為0.4mL，相對於此，實施例2~4中腔室部8之容積(第1腔室部8A與第2腔室 部之容積的合計)分別為2.1mL、3.5mL、7.9mL。又，實施例2~4中香味源收容莢3係與第4A圖說明之實施例1中的香味源收容莢3相同。 Next, Embodiments 2 to 12 in which the volume (volume) of the chamber portion 8, the opening position, the number of openings, and the opening diameter of the air inlet hole 9 are changed in Embodiment 1 will be described. Fig. 10 is a diagram showing specifications of Examples 1 to 12 and Comparative Example 1 at a glance. FIG. 10 shows the air inflow rate R pod of Examples 1 to 12 and Comparative Example 1, the smoke temperature and the TPM reduction rate of Examples 1 to 8 and Comparative Example 1 together. Air inflow rate R pod described later in detail. The “opening position (mm)” in FIG. 10 refers to the distance from the open end (steam release outlet) 31c of the upper portion of the fragrance source receiving pod 3 to the air entry hole 9. The “opening height ratio (%)” in FIG. 10 means the “opening height ratio of the air inlet hole”, as described above, and refers to the length of the steam release hole 31c to the air inlet hole 9 with respect to the steam release outlet. The ratio from 31c to the length of the suction hole 200 (the upper end of the first chamber portion 8A). In addition, in Examples 1 to 8, 11, and 12, two air inlet holes 9 are arranged opposite to each other at a position centered on the central axis of the device and 180 ° apart in the circumferential direction. In addition, according to Example 9, the four air inlet holes 9 are arranged at positions which are centered on the central axis of the device and are 90 ° apart in the circumferential direction. Here, Examples 2 to 12 adopt the non-ventilating structure of the heating portion in the same manner as in Example 1. In Examples 2 to 4, the volume of the chamber portion 8 as a parameter was changed from that in Example 1. Fig. 11 shows a schematic structure of the devices of the second to fourth embodiments. The volume of the chamber portion 8 in Example 1 (total volume of the first chamber portion 8A and the volume of the second chamber portion) is 0.4 mL. In contrast, the volume of the chamber portion 8 in Examples 2 to 4 ( The total volume of the first chamber portion 8A and the second chamber portion) was 2.1 mL, 3.5 mL, and 7.9 mL, respectively. The fragrance source containing pod 3 in Examples 2 to 4 is the same as the fragrance source containing pod 3 in Example 1 described with reference to FIG. 4A.
第12圖係表示對實施例1~4實施抽煙試驗時的全粒子狀物質(TPM)量之測定結果。由第12圖所示可知，相較於實施例1，增加腔室部容積之實施例2~4中，氣溶膠及蒸氣所含的全粒子狀物質(TPM)量係較實施例1增加。其原因認為如下：由於充分確保腔室部8之容積，在抽煙間隔30秒間，腔室部8內之蒸氣分壓不會過度提高，可抑制收容於香味源收容莢3內之香味源32之香味成分蒸發受到阻礙。亦即，由實施例2~4可知，藉由充分確保腔室部8之容積，可抑制隨著香味成分的蒸發使腔室部8內蒸氣分壓變得過高，藉由順利地促進來自收容於香味源收容莢3內之香味源32的香味成分的蒸發，可增加香味成分的輸送量。又，有關於抽煙試驗時的香味成分輸送量，由於在實施例2~4彼此間並未發現顯著差異，故可認為在香味源收容莢3的上部設置固定容積(例如腔室部8之容積為2.1mL)以上之腔室部8時，無關於腔室部8之容積而可充分地確保香味成分的輸送量。然而，以抽煙裝置的規格而言，腔室部8過大者難以實現小型的抽煙裝置，故腔室部8之容積較佳為20mL以下。 FIG. 12 shows the measurement results of the total particulate matter (TPM) amount when the smoking test was performed for Examples 1 to 4. FIG. As can be seen from FIG. 12, compared with Example 1, the amount of total particulate matter (TPM) contained in aerosols and vapors in Examples 2 to 4 in which the volume of the chamber portion was increased compared to Example 1 was larger than that in Example 1. The reason is considered to be as follows: because the volume of the chamber portion 8 is sufficiently ensured, the partial pressure of the vapor in the chamber portion 8 will not be excessively increased within 30 seconds of the smoking interval, and the amount of the fragrance source 32 contained in the fragrance source storage pod 3 can be suppressed. Evaporation of aroma components is hindered. That is, it can be seen from Examples 2 to 4 that by sufficiently securing the volume of the chamber portion 8, it is possible to suppress the partial pressure of the vapor in the chamber portion 8 from becoming too high as the flavor component evaporates, and to smoothly promote the Evaporation of the flavor components of the flavor source 32 contained in the flavor source storage pod 3 can increase the amount of flavor components to be transported. Regarding the amount of flavor components transported during the smoking test, since no significant difference was found between Examples 2 to 4, it is considered that a fixed volume (e.g., the volume of the chamber portion 8) is provided in the upper portion of the flavor source housing pod 3. When the chamber portion 8 is 2.1 mL or more, the amount of aroma components can be sufficiently ensured regardless of the volume of the chamber portion 8. However, in terms of the specifications of the smoking device, it is difficult to realize a small-sized smoking device if the chamber portion 8 is too large. Therefore, the volume of the chamber portion 8 is preferably 20 mL or less.
接著說明變更作為參數之空氣進入孔9之開孔位置、開孔數、開孔徑時之影響。第13圖係表示對實施例1、2、5實施抽煙試驗時的全粒子狀物質(TPM)量之測 定結果之圖。第14圖係表示對實施例1、3、6實施抽煙試驗時的全粒子狀物質(TPM)量之測定結果之圖。第15圖係表示對實施例1、4、7、8實施抽煙試驗時的全粒子狀物質(TPM)量之測定結果之圖。 Next, the effect of changing the opening position, the number of openings, and the opening diameter of the air inlet hole 9 as parameters will be described. Fig. 13 shows the measurement of the total particulate matter (TPM) amount when the smoking test was performed in Examples 1, 2, and 5. Fixed results. FIG. 14 is a graph showing the measurement results of the total particulate matter (TPM) amount when the smoking test was performed for Examples 1, 3, and 6. FIG. Fig. 15 is a graph showing the measurement results of the total particulate matter (TPM) amount when the smoking test was performed for Examples 1, 4, 7, and 8;
如第15圖所示，腔室部8之容積為7.9mL且空氣進入孔9之開孔位置為43mm(「空氣進入孔之開孔高度比率」在63%之位置)之實施例8中，至大致第十五次抽吸為止，可維持充分量之成分輸送量。其原因認為如下：由於空氣進入孔9之位置遠離香味源收容莢3而抑制了積蓄於腔室部8之香味成分的蒸氣之吸嘗量。因此，為了使香味成分的蒸發量相較於未設置腔室部8之構造增加，並且使成分輸送量安定化，較佳為使腔室部8之容積為7.9mL以上，且在空氣進入孔9之開孔高度比率為63%以上之位置設置空氣進入孔9。 As shown in Fig. 15, the volume of the chamber portion 8 is 7.9 mL and the opening position of the air inlet hole 9 is 43 mm (the "opening height ratio of the air inlet hole" is at a position of 63%). Until the fifteenth suction, a sufficient amount of component delivery can be maintained. The reason for this is considered to be as follows: since the position of the air inlet hole 9 is far from the fragrance source accommodating pod 3, the amount of vapor of the fragrance component stored in the chamber portion 8 is suppressed. Therefore, in order to increase the evaporation amount of the fragrance component compared to the structure without the chamber portion 8 and stabilize the component transportation amount, it is preferable that the volume of the chamber portion 8 is 7.9 mL or more and the air inlet hole is An air inlet hole 9 is provided at a position where the ratio of the opening height of 9 is 63% or more.
接著比較各實施例及比較例1中之流入香味源收容莢3內之空氣流入量率Rpod。空氣流入量率Rpod係在以抽煙機抽煙的2秒間，藉由流體解析算出通過腔室部8而進入香味源收容莢3內之空氣量相對於由空氣進入孔9流入腔室部之進入空氣之全空氣量之比例。又，計算空氣流入量率Rpod時的溫度條件，係以使香味源收容莢3(耐熱容器31)之壁面及莢內部之空間部為500K(kelvin；絕對溫度)，其他的空間為300K之初始條件，實施流體解析。流體解 析係使用Fluent version 18.0(ANSYS)，在抽煙流量55mL/2秒之型態曲線下實施解析。又，流入香味源收容莢3內之空氣流入量率Rpod(%)係使用下式計算。 Next, the air inflow rate R pod flowing into the fragrance source accommodating pod 3 in each Example and Comparative Example 1 is compared. R pod-based air inflow rate between smoking cigarettes machine smoking two seconds, by fluid analysis calculated through the chamber 8 into the flow into the chamber portion of the air amount within the flavor source storage pods 3 relative to the entrance of the air hole 9 The proportion of total air volume of air. In addition, the temperature conditions at the time when the air inflow rate R pod is calculated are such that the wall surface of the fragrance source housing pod 3 (heat-resistant container 31) and the space inside the pod are 500K (kelvin; absolute temperature), and other spaces are 300K Initial conditions were performed for fluid analysis. The fluid analysis was performed using Fluent version 18.0 (ANSYS), and the analysis was performed under the shape curve of 55mL / 2 seconds of smoking flow. The air inflow rate R pod (%) flowing into the fragrance source storage pod 3 is calculated using the following formula.
在此，Vpod係在以抽煙機抽煙的2秒間進入香味源收容莢3內部之空氣體積，Vinhalation係抽煙容量之55mL之固定值。又，本流體解析中同時計測進入(流入)香味源收容莢3內之空氣及由香味源收容莢3流出之空氣，並由其值計算進入香味源收容莢3內之空氣體積，因此空氣流入量率Rpod之計算實際數值要乘以0.5。解析結果係如第10圖所示。實施例1之空氣流入量率Rpod為0.15%，可確認空氣幾乎未進入香味源收容莢3內。 Here, V pod is the volume of air that enters the interior of the fragrance source pod 3 within 2 seconds of smoking with a smoking machine, and V inhalation is a fixed value of 55 mL of smoking capacity. In addition, in this fluid analysis, the air entering (flowing into) the fragrance source containing pod 3 and the air flowing out of the fragrance source containing pod 3 are measured at the same time, and the volume of air entering the fragrance source containing pod 3 is calculated from its value. The actual value of the measurement rate R pod should be multiplied by 0.5. The analysis results are shown in Figure 10. The air inflow rate R pod of Example 1 was 0.15%, and it was confirmed that the air hardly entered the fragrance source receiving pod 3.
如第10圖所示，相較於其他實施例，實施例2~4中，空氣流入量率Rpod高於10%以上。其原因認為如下：由配置於腔室部8中的對向位置之二個空氣進入孔9流入之進入空氣係在腔室部8內對沖而生成朝下之氣流，藉由該氣流而使進入空氣進入香味源收容莢3內。舉例而言，第16圖表示實施例2之裝置中進入空氣之流體通過線。 As shown in FIG. 10, compared to other embodiments, the air inflow rate R pod in Examples 2 to 4 is higher than 10%. The reason is considered to be as follows: the incoming air flowing in from the two air inlet holes 9 disposed at the opposite positions in the chamber portion 8 is opposed in the chamber portion 8 to generate a downward airflow, and the airflow is caused to enter The air enters the fragrance source containing pod 3. For example, FIG. 16 shows a fluid passing line for entering air in the device of the second embodiment.
另一方面，空氣進入孔9之開孔位置遠離香味源收容莢3之實施例5~8中，進入空氣在腔室部8之中心部對沖而生成朝下之氣流，該氣流未到達香味源收容莢3，而得到空氣流入量率Rpod為1%以下之結果。又，關於 空氣進入孔9之開孔數，四個空氣進入孔9配置於以抽煙裝置之中心軸CL為中心，於周方向分別間隔90°之位置之實施例9中，可觀察到空氣流入量率Rpod有與空氣進入孔9之開孔數為二個之實施例1相同之傾向。 On the other hand, in Embodiments 5 to 8 where the opening position of the air inlet hole 9 is far from the fragrance source receiving pod 3, the incoming air hedges at the center of the chamber portion 8 to generate a downward airflow, which does not reach the fragrance source. The pod 3 was contained, and the air inflow rate R pod was 1% or less. Regarding the number of openings of the air inlet holes 9, four air inlet holes 9 are arranged around the central axis CL of the smoking device and spaced 90 ° apart from each other in the circumferential direction, and air inflow can be observed. The measurement rate R pod tends to have the same tendency as in Example 1 where the number of openings of the air inlet holes 9 is two.
在此，比較僅空氣進入孔9之開孔數相異之實施例1及實施例10之空氣流入量率Rpod時，結果如下：相較於空氣進入孔9為二個之實施例1(Rpod：0.15%)，空氣進入孔9為一個之實施例10(Rpod：12.4%)其空氣流入量率Rpod提高。其主原因認為如下：相較於空氣進入孔9為二個之實施例1，空氣進入孔9為一個之實施例10係在吸嘗(抽吸)時通過空氣進入孔9而由外部流入腔室部8內之空氣之線速度較快，且在空氣進入孔9為一個之實施例10中，由空氣進入孔9流入之空氣吹襲於與空氣進入孔9對向之腔室部8內壁面，而容易產生向下方亦即香味源收容莢3方向之氣流。又，吸嘗(抽吸)時通過空氣進入孔9而由外部流入腔室部8內之空氣之線速度，在實施例1為146.2m/秒，相對於此，在實施例10為257.9m/秒。由以上可知，採用加熱部非通氣構造之實施例中，較佳為在腔室部8設置複數個空氣進入孔9。 Here, the number of comparison only air enters the aperture hole 9 of Example 1 and Example 10 of the air inflow rate R pod different embodiment of the embodiment, results were as follows: Compared to the air inlet opening 9 for the two embodiments of Example 1 ( R pod : 0.15%) and Example 10 (R pod : 12.4%) in which the air inlet 9 is one, the air inflow rate R pod is increased. The main reason is as follows: Compared with the embodiment 1 in which the air inlet holes 9 are two, the embodiment 10 in which the air inlet holes 9 are one is that the air enters the cavity from the outside through the air inlet holes 9 during suction (suction). The linear velocity of the air in the chamber portion 8 is fast, and in the embodiment 10 in which the air inlet hole 9 is one, the air flowing in from the air inlet hole 9 blows into the chamber portion 8 opposite to the air inlet hole 9. Wall surface, and it is easy to generate airflow in the downward direction, that is, the direction in which the fragrance source contains the pod 3. In addition, the linear velocity of the air flowing into the chamber portion 8 from the outside through the air entry hole 9 during the suction (suction) was 146.2 m / sec in Example 1, whereas it was 257.9 m in Example 10. /second. As can be seen from the above, in the embodiment employing the non-ventilating structure of the heating portion, it is preferable to provide a plurality of air inlet holes 9 in the chamber portion 8.
進一步改變空氣進入孔9之開孔徑(直徑)時，相較於開孔徑為0.8mm之實施例12，開孔徑為0.2mm之實施例11中的進入空氣線速度約成為8倍，顯著形成往香味源收容莢3方向之氣流，藉此提高實施例11之空氣流入量率Rpod，但由於Rpod本身為1%以下，故可確認開口徑 之影響較小。 When the opening diameter (diameter) of the air inlet hole 9 is further changed, compared with Example 12 having an opening diameter of 0.8 mm, the linear velocity of the entering air in Example 11 having an opening diameter of 0.2 mm becomes approximately 8 times, which significantly forms The fragrance source accommodates the airflow in the direction of the pod 3, thereby increasing the air inflow rate R pod of Example 11, but since the R pod itself is 1% or less, it can be confirmed that the influence of the opening diameter is small.
又，依據上述驗證結果，採用了在香味源收容莢3方向的後段配置之腔室部8設置空氣進入孔9之加熱部非通氣構造之各實施例中，若空氣流入量率Rpod為25%以下，則可充分具有加熱部非通氣構造之特徵，較佳為空氣流入量率Rpod為15%以下，更佳為空氣流入量率Rpod為1%以下。又，腔室部8之容積(第1腔室部8A及第2腔室部8B之容積的合計)較佳為2.1mL以上，更佳為7.9mL以上。又，就於腔室部8設置空氣進入孔9之設置高度而言，開孔位置越高，亦即空氣進入孔9之開孔高度比率(蒸氣釋出口31c至空氣進入孔9之長度之比率相對於蒸氣釋出口31c至吸口孔200之長度)越大越佳，較佳係將空氣進入孔9之開孔高度比率設為63%以上。有鑑於作為抽煙具來使用時必需設置人能夠以嘴巴叼住之吸嘴長度，又，若空氣進入孔9設置於包含口腔內之位置時，則空氣無法流入，故認為空氣進入孔9之開孔高度比率設為90%以下係較妥當的範圍。又，有關於空氣進入孔9之開孔徑(直徑)，較佳範圍可舉例如0.2mm以上0.8mm以下。 Further, according to the verification results, using the chamber portion Disposing the flavor source storage pods third direction rear section 8 disposed air into each of air-impermeable structure of the heated portion of the hole 9 of the embodiment, R pod when the air inflow rate of 25 % Or less, it can sufficiently have the characteristics of the non-ventilating structure of the heating portion. It is preferable that the air inflow rate R pod is 15% or less, and more preferably the air inflow rate R pod is 1% or less. The volume of the chamber portion 8 (total volume of the first and second chamber portions 8A and 8B) is preferably 2.1 mL or more, and more preferably 7.9 mL or more. In addition, in terms of the installation height of the air inlet hole 9 provided in the chamber portion 8, the higher the position of the opening, that is, the ratio of the height of the air inlet hole 9 (the ratio of the length of the steam outlet 31c to the length of the air inlet hole 9) Relative to the length of the vapor release outlet 31c to the suction port hole 200, the larger the better, it is preferable to set the ratio of the height of the opening of the air inlet hole 9 to 63% or more. Considering that it is necessary to set the length of the mouthpiece that can be held by a person when using it as a smoking device, and if the air inlet hole 9 is provided at a position including the oral cavity, air cannot flow in, so it is considered that the air inlet hole 9 is opened. It is more appropriate to set the hole height ratio to 90% or less. The opening diameter (diameter) of the air inlet hole 9 is preferably in the range of 0.2 mm to 0.8 mm.
又，如第10圖所示，相對於比較例1中的煙溫度超過100℃，實施例1~12中的煙溫度維持在60℃以下。如上述，若使抽煙時之香味源32的蒸氣成分的溫度為60℃以下，則可供給對抽煙者而言為容易抽煙之溫度域之氣溶膠。 As shown in Fig. 10, the smoke temperature in Examples 1 to 12 was maintained at 60 ° C or lower with respect to the smoke temperature in Comparative Example 1 exceeding 100 ° C. As described above, if the temperature of the vapor component of the fragrance source 32 at the time of smoking is 60 ° C. or lower, an aerosol in a temperature range that is easy for a smoker to smoke can be supplied.
又，本實施形態之非燃燒加熱型抽煙物品1 中的空氣進入孔9係設定為空氣流入腔室部8內時的流入方向(空氣進入孔9之軸線方向)相對於中心軸CL垂直之方向，惟，如第17圖所示的變形例，亦可為空氣流入腔室部8內時的流入方向(空氣進入孔9之軸線方向)以朝向著吸嘴20之吸口孔200側之方式相對於中心軸CL傾斜。藉此，由空氣進入孔9流入腔室部8之進入空氣更難以進入香味源收容莢3內，故可更適合地實現煙溫度的上升抑制及香味成分的安定供給。 The non-combustion heating type smoking article 1 of the present embodiment The air inlet hole 9 is set in a direction in which the air flows into the chamber portion 8 (the axial direction of the air inlet hole 9) is perpendicular to the central axis CL. However, as shown in the modification shown in FIG. 17, The inflow direction (the axial direction of the air inlet hole 9) when the air flows into the chamber portion 8 may be inclined with respect to the central axis CL so as to face the suction hole 200 side of the suction nozzle 20. Thereby, it is more difficult for the incoming air flowing into the chamber portion 8 from the air inlet 9 to enter the fragrance source accommodation pod 3, so that it is possible to more suitably realize the suppression of the rise in smoke temperature and the stable supply of fragrance components.
