Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are designated by the same reference numerals and duplicate description will be omitted.

FIG. 1 is an overall perspective view of the non-combustion heating type flavor suction device according to the present embodiment. As shown in FIG. 1, the non-combustion heating type flavor suction device 100 has a reusable power supply unit 90 and a cartridge 10 that can be attached to the power supply unit 90. The power supply unit 90 has a power supply 92 inside thereof, and the power supply unit 92 is configured to supply electric power to the cartridge 10 attached to the power supply unit 90. The cartridge 10 has a vent 12 at its tip. The user can suck the aerosol produced by the non-combustion heating type flavor suction device 100 from the vent 12.

FIG. 2 is an exploded perspective view of the cartridge 10 shown in FIG. In the present specification, the side facing the power supply unit 90 in a state where the cartridge 10 is attached to the power supply unit 90 may be referred to as a “rear end of the cartridge 10”. Further, the side opposite to the rear end of the cartridge 10 may be referred to as the "tip of the cartridge 10." Further, the direction connecting the rear end and the tip of the cartridge 10 may be referred to as a "first direction", and the direction orthogonal to the first direction may be referred to as a "second direction".

The cartridge 10 has a tank 30, an atomizing portion 14, an atomizing portion fixing member 16, a mouthpiece 18, and a cap 20. The tank 30 holds an aerosol source containing water, glycerin, propylene glycol, etc. inside the tank 30. Further, the tank 30 is provided with an atomization chamber 33 at a position near the rear end in the first direction. The atomizing unit 14 is configured to atomize the aerosol source supplied from the tank 30. In the present embodiment, as will be described later in relation to FIG. 3, the atomizing portion 14 is formed by a coil in which a resistance heating element is wound around the outer circumference of a tubular wick made of glass fiber or the like. The atomizing unit 14 includes electrical contacts as described later in connection with FIG. When the cartridge 10 is attached to the power supply unit 90, the electrode terminals of the power supply unit 90 and the electrical contacts of the atomization unit 14 are electrically connected, and power can be supplied from the power supply unit 90 to the atomization unit 14.

In order to supply an aerosol source to the resistance heating element, the atomizing unit 14 has a tubular wick made of glass fiber or the like, a wick made of organic fiber (cellulose or the like), or a flat plate or tubular ceramic or the like. Porous material can be adopted as a wick. Further, as the resistance heating element, for example, a metal such as nichrome or stainless steel or a non-metal such as carbon can be used. When the wick has a tubular shape, the heat generating resistor may be wound in a coil shape or may be arranged along the tubular wick. When the wick has a flat plate shape, the resistance heating elements may be arranged linearly on the wick plane or may be arranged meanderingly. The atomizing unit 14 may be configured to atomize the aerosol source by ultrasonic waves or induction heating instead of the resistance heating element. The cartridge 10 may have a plurality of atomizing portions 14. The atomization chamber 33 is not limited to a position near the rear end in the first direction of the tank 30, and may exist at any position in the tank 30 or outside the tank 30. Further, the atomization chamber 33 may be defined by a member detachable from the tank 30.

The cap 20 is attached to the rear end of the tank 30 in the first direction to protect the atomization chamber 33 of the tank 30 and is removed when the cartridge 10 is used. The atomizing portion fixing member 16 is fixed in the atomizing chamber 33 of the tank 30 while holding the atomizing portion 14. As a result, a part of the wick of the atomizing unit 14 comes into contact with the aerosol source held in the tank 30, and the aerosol source is supplied to the wick. The mouthpiece 18 is attached to the tip of the tank 30 in the first direction. Further, the mouthpiece 18 includes the vent 12 shown in FIG.

FIG. 3 is a schematic side sectional view of the tank 30 shown in FIG. In FIG. 3, the atomizing portion fixing member 16 shown in FIG. 2 is not shown. As shown, the tank 30 has an upper wall portion 30a at the tip in the first direction, a bottom wall portion 30b at the rear end in the first direction, and an outer wall portion 30c constituting the outer peripheral surface thereof. Further, the tank 30 includes an inner wall portion 34 (corresponding to an example of the wall portion) that defines at least a part of the aerosol flow path 32. That is, the tank 30 defines an aerosol flow path 32 extending in the first direction between the rear end and the tip of the tank 30 at a substantially central portion inside the tank 30 by the inner wall portion 34. In the present specification, the outer wall portion 30c and the inner wall portion 34 of the tank 30 are walls forming the side surface of the tank 30, and may also be a side wall. Further, in the present specification, the side wall of the tank 30 means a wall having a function of holding an aerosol source in the tank 30 together with the upper wall portion 30a and the bottom wall portion 30b of the tank 30, and the upper wall portion 30a of the tank 30. Alternatively, it may or may not be integrally formed with the bottom wall portion 30b. In the present embodiment, the inner wall portion 34 defining the aerosol flow path 32 constitutes a part of the side wall of the tank 30. Not limited to this, at least a part of the aerosol flow path 32 may be defined by a wall portion made of a member different from the side wall of the tank 30.

As shown in the figure, the atomizing unit 14 is fixed in the atomizing chamber 33 of the tank 30. Specifically, the atomizing unit 14 includes a tubular wick 14a and a coil 14b wound around the wick 14a, and is arranged in the atomizing chamber 33 so that the wick 14a extends in the second direction. The wick 14a absorbs and retains the aerosol source held in the tank 30. The atomizing unit 14 further includes an electric contact 14c for supplying electric power to the coil 14b. When the cartridge 10 is attached to the power supply unit 90 shown in FIG. 1, the contacts of the power supply unit 90 and the electrical contacts 14c shown in FIG. 3 are electrically connected, and power is supplied to the coil 14b from the power supply unit 90.

When electric power is supplied to the coil 14b, the coil 14b generates heat and atomizes the aerosol source held in the wick 14a to generate an aerosol. The aerosol generated in the atomization chamber 33 reaches the user's mouth through the vent 12 of the mouthpiece 18 through the aerosol flow path 32 as the user sucks. Therefore, the tank 30 and the atomizing unit 14 function as an atomizing unit for atomizing the aerosol source.

As described above, when the non-combustion heating type flavor suction device 100 is used, the aerosol generated from the atomizing portion 14 aggregates on the wall surface of the inner wall portion 34 defining the aerosol flow path 32, and droplets are formed. Sometimes. If the use of the non-combustion heating type flavor suction device 100 is further continued, agglomerated droplets may accumulate in a columnar shape in the aerosol flow path 32. The columnar droplets may move toward the mouthpiece 18 side with the suction of the non-combustion heating type flavor suction device 100 of the user, reach the mouth of the user, and cause discomfort to the user.

Therefore, the non-combustion heating type flavor suction device 100 according to the present embodiment has a liquid evacuation portion for retracting the droplets aggregated on the inner wall portion 34 from the aerosol flow path 32. FIG. 4A is a top view of the inner wall portion 34 of the tank 30 shown in FIG. FIG. 4B is a side sectional view of the inner wall portion 34 of the tank 30 in the arrow view BB of FIG. 4A. In FIGS. 4A and 4B, only the inner wall portion 34 of the tank 30 is shown as an excerpt.

As shown in FIGS. 4A and 4B, the aerosol flow path 32 defined by the inner wall portion 34 communicates with the first aerosol flow path 32a and the downstream side (that is, the tip end) of the first aerosol flow path 32a. It has a flow path 32b. In other words, the inner wall portion 34 is a first aerosol flow path wall portion 34a that defines at least a part of the first aerosol flow path 32a, and a second aerosol flow path wall that defines at least a part of the second aerosol flow path 32b. It has a part 34b and. In the present embodiment, the first aerosol flow path wall portion 34a and the second aerosol flow path wall portion 34b each form a part of the side wall of the tank 30. Not limited to this, only the second aerosol flow path wall portion 34b constitutes at least a part of the side wall of the tank 30, and the first aerosol flow path wall portion 34a is composed of a wall member different from the side wall of the tank 30. , May be located outside the tank 30.

As shown in FIG. 4A, in the present embodiment, the cross-sectional shapes of the first aerosol flow path 32a and the second aerosol flow path 32b in the second direction are circular. Further, in the present embodiment, the cross-sectional shape of the first aerosol flow path 32a in the second direction is the same as the cross-sectional shape of the second aerosol flow path 32b in the second direction. Further, in the present embodiment, the first aerosol flow path 32a and the second aerosol flow path 32b have a constant cross-sectional shape and cross-sectional area in the first direction. That is, the cross-sectional shape and cross-sectional area of the first aerosol flow path 32a and the second aerosol flow path 32b do not change along the length direction thereof.

As shown in FIG. 4B, the inner wall portion 34 includes a flat surface portion 40 parallel to the second direction at the boundary between the first aerosol flow path 32a and the second aerosol flow path 32b, and a pair of flat surface portions 40 extending from the flat surface portion 40 to the tip. It has a slit 42. The flat surface portion 40 and the slit 42 are located outside the second aerosol flow path 32b in the second direction. As shown in FIG. 4A, in the present embodiment, the inner wall portion 34 is provided with a pair of slits 42 so as to sandwich the second aerosol flow path 32b. Not limited to this, the inner wall portion 34 may be provided with one or three or more slits 42. As shown in FIG. 4A, the inner wall portion 34 includes a corner portion 42a forming a slit 42 when viewed from the first direction. As shown in FIG. 4A, the tip of the slit 42 is open.

In the present specification, as shown in FIG. 4A, the width W means the length including the diameter φ of the second aerosol flow path 32b and the depth of the pair of slits 42, and the height H of the slits 42 is , The length of the slit 42 in the thickness direction.

The cross-sectional shape of the slit 42 in the second direction is not limited to the shape shown in FIG. 4A. 4C and 4D are top views of the inner wall portion 34 of the tank 30 according to another embodiment. In the example shown in FIG. 4C, the cross-sectional shape of the corner portion 42a of the slit 42 in the second direction is formed in a rounded shape. That is, the corner portion 42a includes not only the 90-degree corner portion 42a but also the rounded corner portion 42a. Further, in the example shown in FIG. 4D, the cross-sectional shape of the slit 42 in the second direction is formed in a semicircular shape. The slit 42 is not limited to the cross-sectional shape shown in FIGS. 4A, 4C, and 4D, and may have an arbitrary cross-sectional shape including a polygon such as a triangle.

When the non-combustion heating type flavor suction device 100 is used, the aerosol generated from the atomizing portion 14 is the first aerosol flow path 32a and the second aerosol flow path defined by the inner wall portion 34 shown in FIGS. 4A and 4B. It passes through 32b. At this time, the aerosol may aggregate on the wall surface of the first aerosol flow path wall portion 34a or the second aerosol flow path wall portion 34b, and droplets may be formed.

When droplets continue to aggregate on the wall surface of the first aerosol flow path wall portion 34a and / or the second aerosol flow path wall portion 34b, the droplets are deposited so as to block the first aerosol flow path 32a, and as a result, the first aerosol flow path wall portion 34a and / or the second aerosol flow path wall portion 34b. 1 Droplets can be formed in columns in the aerosol flow path 32a. The columnar droplets move to the mouthpiece 18 side, that is, to the second aerosol flow path 32b side as the user sucks the non-combustion heating type flavor suction device 100. Here, when the columnar droplet reaches the second aerosol flow path 32b, one of the droplets enters the space defined by the flat surface portion 40 formed at the boundary between the first aerosol flow path 32a and the second aerosol flow path 32b. The part evacuates. Since it is difficult for air to flow in the space near the flat surface portion 40, the flow velocity of the air passing through the flat surface portion 40 is smaller than the flow velocity of the second aerosol flow path 32b. Therefore, the droplets evacuated to the space defined by the flat surface portion 40 are less likely to move toward the mouthpiece 18, so that it is possible to prevent the droplets from reaching the user's mouth. That is, the space defined by the flat surface portion 40 functions as a part of the liquid evacuation portion in which the aggregated droplets evacuate from the second aerosol flow path 32b.

Further, the columnar droplets that have reached the second aerosol flow path 32b are also evacuated to the inside of the slit 42 extending from the flat surface portion 40. As a result, the droplet is no longer columnar and is located inside the slit 42, that is, in the space defined by the slit 42. Since the slit 42 includes the corner portion 42a as described above, the droplet is held by the corner portion 42a of the slit 42 by the capillary action. Since the slit 42 is located outside the first aerosol flow path 32a and the second aerosol flow path 32b in the second direction, the flow velocity of the air passing through the slit 42 is higher than the flow velocity of the second aerosol flow path 32b. Small. Therefore, the droplets evacuated to the space defined by the slit 42 are less likely to move toward the mouthpiece 18, so that it is possible to prevent the droplets from reaching the user's mouth. That is, the space defined by the slit 42 functions as a liquid evacuation portion in which the agglomerated droplets evacuate from the second aerosol flow path 32b.

In order to prevent droplets from accumulating in a columnar shape in the aerosol flow path 32, it is conceivable to increase the width or diameter of the aerosol flow path 32 over the entire length of the aerosol flow path 32. On the other hand, the aerosol flow path 32 may be provided so as to extend to the side or the inside of the tank 30 as in the present embodiment. In this case, if the width or diameter of the aerosol flow path 32 is increased over the entire length, the space of the tank 30 is reduced accordingly, so that the volume of the tank 30 for storing the aerosol source is reduced. On the other hand, the non-combustion heating type flavor suction device 100 according to the present embodiment is provided in the second aerosol flow path 32b, and the second aerosol is provided from the boundary between the first aerosol flow path 32a and the second aerosol flow path 32b. A liquid evacuation portion extending downstream of the flow path 32b is provided. Specifically, in the present embodiment, the non-combustion heating type flavor suction device 100 evacuates the space defined by the flat surface portion 40 and the space defined by the slit 42, particularly the space defined by the corner portion 42a. Prepare as a department. In particular, the space defined by the corner portion 42a has an excellent liquid retention capacity due to the action of capillary force, so that the liquid once reaching the liquid storage portion forms columnar droplets again in the first aerosol flow path 32a. Can be suppressed. Therefore, as compared with the case where the width or diameter of the aerosol flow path 32 is increased over the entire first direction of the inner wall portion 34, it is possible to suppress the decrease in the capacity of the tank 30 and prevent the droplets from reaching the user's mouth. can do. Further, in the present embodiment, it is possible to prevent the droplets from reaching the user's mouth without providing a separate member in the tank 30. As a result, it is possible to suppress an increase in member cost and the influence of providing a separate member.

In the present embodiment, the flat surface portion 40 is parallel to the second direction, but is not limited to this. 4E and 4F are side sectional views of the inner wall portion 34 of the tank 30 according to another embodiment. In the example shown in FIGS. 4E and 4F, the flat surface portion 40 is provided so as to be inclined with respect to the second direction. Specifically, the flat surface portion 40 shown in FIG. 4B extends at a right angle to the first aerosol flow path wall portion 34a, whereas in the example shown in FIG. 4E, the flat surface portion 40 is the first aerosol flow path wall. It extends so as to be inclined at an obtuse angle with respect to the portion 34a. In other words, in the example shown in FIG. 4E, the flat surface portion 40 extends from the first aerosol flow path wall portion 34a toward the mouthpiece 18 side. Further, in the example shown in FIG. 4F, the flat surface portion 40 extends so as to be inclined at an acute angle with respect to the first aerosol flow path wall portion 34a. In other words, in the example shown in FIG. 4F, the flat surface portion 40 extends from the first aerosol flow path wall portion 34a toward the opposite side of the mouthpiece 18. In the example shown in FIG. 4F, the concave space S1 is determined by the flat surface portion 40 and the slit 42. The concave space S1 forms a part of the liquid evacuation portion, and has an excellent liquid holding ability due to the action of capillary force. Therefore, the concave space S1 can prevent the liquid that has reached the space S1 from forming columnar droplets again in the first aerosol flow path 32a.

In the present embodiment, the aerosol flow path 32 is configured to extend to the inner center of the tank 30. Not limited to this, the aerosol flow path 32 may be provided on the side of the tank 30, and the outer wall portion 30c of the tank 30 may function as a wall portion that defines at least a part of the aerosol flow path 32. 5A and 5B are schematic side sectional views showing a tank 30 according to another embodiment. In the example shown in FIG. 5A, the tank 30 and the atomizing portion 14 are housed in the housing 60, and the aerosol flow path 32 is formed on one side of the tank 30. In the example shown in FIG. 5B, the tank 30 and the atomizing portion 14 are housed in the housing 60, and aerosol flow paths 32 are formed on both sides of the tank 30. Arrows A1 and A2 in FIGS. 5A and 5B indicate the flow of air or aerosol through the housing 60.

<Experimental example 1>
An experiment was conducted to evaluate the amount of droplets that reached the user's mouth (the amount of droplets that reached the user's mouth) according to the shape of the liquid evacuation part. FIG. 6 is a top view of the inner wall portion 34 of the tank 30 used in Experimental Example 1. In this experiment, when a predetermined amount of liquid is injected into the first aerosol flow path 32a defined by the inner wall portion 34 according to Examples 1 to 9 shown in FIG. 6 so as to form a columnar shape and sucked under predetermined conditions. The amount of liquid scattered from the second aerosol flow path 32b to the tip of the inner wall portion 34 was measured.

In the inner wall portions 34 according to the first to ninth embodiments, the length of the first aerosol flow path 32a in the first direction is 10 mm, and the length of the second aerosol flow path 32b and the slit 42 in the first direction is 20 mm. did. The diameter φ of the first aerosol flow path 32a and the second aerosol flow path 32b was set to 2 mm. When the width W and the height H of the slit 42 and the second aerosol flow path wall portion 34b are defined as shown in FIG. 4A, the width W and the height H of Examples 1 to 9 are as follows. Is.
Example 1 Width W = 6 mm, height H = 2 mm
Example 2 Width W = 6 mm, height H = 1 mm
Example 3 Width W = 6 mm, Height H = 0.6 mm
Example 4 Width W = 4 mm, Height H = 2 mm
Example 5 Width W = 4 mm, Height H = 1 mm
Example 6 Width W = 4 mm, Height H = 0.6 mm
Example 7 Width W = 3 mm, Height H = 2 mm
Example 8 Width W = 3 mm, Height H = 1 mm
Example 9 Width W = 3 mm, Height H = 0.6 mm

That is, the cross-sectional shapes of the second aerosol flow path 32b and the liquid evacuation portion (slit 42) of Examples 1, 4 and 7 in the second direction are square as a whole. Further, in Examples 2, 3, 5, 6, 8 and 9, the height H of the slit 42 is smaller than the diameter φ in the second direction of the second aerosol flow path 32b.

Further, the tank 30 provided with the inner wall portion 34 not provided with the liquid evacuation portion was designated as Comparative Example 1. That is, the inner wall portion 34 of Comparative Example 1 has the same shape as that of Examples 1 to 9 except that the slit 42 and the flat surface portion 40 are not provided.

The suction conditions are as follows.
Suction capacity 2400cc / min
Suction time 3 seconds Number of puffs 1 time N number (sample size) 3
Orientation of tank 30 (angle in the first direction) 45 ° diagonally with respect to the vertical
Liquid composition Glycerin: Propylene glycol: Water = 45:45:10
Liquid injection amount: 40 μl

Table 1 shows the results of the experiment under the above conditions.

In Table 1, the liquid evacuation portion area is the cross-sectional area of the slit 42 in the second direction, and does not include the cross-sectional area of the second aerosol flow path 32b. Further, in Table 1, (area of liquid evacuation portion + cross-sectional area of the second aerosol flow path in the second direction) / cross-sectional area of the first aerosol flow path in the second direction is the cross-sectional area of the second aerosol flow path 32b and the slit 42. The ratio of the cross-sectional area in the second direction to the cross-sectional area of the first aerosol flow path 32a in the second direction is shown. As shown in Table 1, the amount of droplets reached in each of Examples 1 to 9 is smaller than the amount of droplets reached in Comparative Example 1 not provided with the liquid evacuation portion. That is, by providing the liquid evacuation portion on the inner wall portion 34, the amount of droplets reaching can be reduced. Therefore, according to this experiment, it can be seen that the amount of droplets reached can be reduced when the above ratio is more than 1 and 4.0 or less.

Further, in Example 1, the amount of droplets reached was 0.9, which was significantly reduced as compared with Comparative Example 1, but the area of the liquid evacuation portion, that is, the cross-sectional area of the slit 42 in the second direction was 8. It is 86 mm ² , and the area of the liquid evacuation portion is larger than that of Examples 2 to 9. If the area of the liquid evacuation portion is large, the volume of the tank 30 may be affected. Therefore, according to this experiment, it can be seen that the above ratio is preferably about 3 or less.

With reference to the droplet arrival amount of Examples 1 to 9, Examples 1-5 and 7 can significantly reduce the droplet arrival amount as compared with other examples. Therefore, according to this experiment, it can be seen that the above ratio is particularly preferable to be 1.5 or more.

The outer surface shape of the inner wall portion 34 shown in FIG. 6 has the same diameter for the experiment. However, the outer surface shape of the inner wall portion 34 can be designed to correspond to the shapes of the second aerosol flow path 32b and the liquid evacuation portion. 7A and 7B are schematic views showing an inner wall portion 34 having an outer surface shape that does not correspond to the shapes of the second aerosol flow path 32b and the liquid evacuation portion. 7C and 7D are schematic views showing an inner wall portion 34 having an outer surface shape corresponding to the shapes of the second aerosol flow path 32b and the liquid evacuation portion. In the example shown in FIG. 7A, the outer surface shape of the inner wall portion 34 is similar to the cross-sectional shape of the second aerosol flow path 32b (that is, circular). The thickness of the inner wall portion 34 shown in FIG. 7A is relatively thin in the vicinity of the liquid evacuation portion (slit 42). Therefore, if the outer surface shape of the inner wall portion 34 is designed so that the inner wall portion 34 has sufficient strength in the thinnest portion, the thickness of the inner wall portion 34 becomes partially excessively thick. In the example of FIG. 7A, the inner wall portion 34 of the portion (upper and lower portions in the figure) defining the second aerosol flow path 32b is excessively thick.

In the example shown in FIG. 7B, the outer surface shape of the inner wall portion 34 is rectangular. In FIG. 7B, the outer surface shape of the inner wall portion 34 shown in FIG. 7A is shown by a broken line for reference. The thickness of the inner wall portion 34 shown in FIG. 7B is relatively thin in the vicinity of the liquid evacuation portion (slit 42), similarly to the inner wall portion 34 shown in FIG. 7A. Therefore, if the outer surface shape of the inner wall portion 34 is designed so that the inner wall portion 34 has sufficient strength in the thinnest portion, the thickness of the inner wall portion 34 becomes partially excessively thick. In the example of FIG. 7B, the inner wall portion 34 of the portion (upper and lower portions in the figure) defining the second aerosol flow path 32b is excessively thick.

On the other hand, in the example shown in FIG. 7C, the outer surface shape of the inner wall portion 34 is elliptical. In FIG. 7C, the outer surface shape of the inner wall portion 34 shown in FIG. 7A is shown by a broken line for reference. The inner wall portion 34 shown in FIG. 7C is designed so that the thickness in the vicinity of the liquid evacuation portion (slit 42) and the thickness of the portion defining the second aerosol flow path 32b (upper and lower portions in the drawing) are close to each other. Therefore, the area occupied by the outer surface shape of the inner wall portion 34 shown in FIG. 7C (the area of the ellipse in FIG. 7C) is the area occupied by the outer surface shape of the inner wall portion 34 shown in FIG. 7A (the area of the circle shown by the broken line in FIG. 7C). It will be smaller than that. That is, the capacity of the tank 30 provided with the inner wall portion 34 shown in FIG. 7C can be increased as compared with the tank 30 provided with the inner wall portion 34 shown in FIG. 7A.

Further, in the example shown in FIG. 7D, the outer surface shape of the inner wall portion 34 is a similar shape to the second aerosol flow path 32b and the liquid evacuation portion (slit 42). In FIG. 7D, the outer surface shape of the inner wall portion 34 shown in FIG. 7A is shown by a broken line for reference. Also in FIG. 7D, the area occupied by the outer surface shape of the inner wall portion 34 is smaller than the area occupied by the outer surface shape of the inner wall portion 34 shown in FIG. 7A (the area of the broken line circle in FIG. 7C). That is, the capacity of the tank 30 provided with the inner wall portion 34 shown in FIG. 7D can be increased as compared with the tank 30 provided with the inner wall portion 34 shown in FIG. 7A. Therefore, as shown in FIGS. 7C and 7D, the shape corresponding to the shapes of the second aerosol flow path 32b and the liquid evacuation portion has an outer surface shape similar to the cross-sectional shape of the second aerosol flow path 32b shown in FIG. 7A. It is a shape having a cross-sectional area smaller than the cross-sectional area of.

<Experimental example 2>
An experiment was conducted to evaluate the amount of droplets reached according to the length of the liquid evacuation section. In this experiment, the inner wall portion 34 (Example 10 and Example 11) in which the width W of the slit 42 is 3.0 mm and the height H is 1.5 mm, and the width W of the slit 42 is 4.5 mm and the height H. The inner wall portion 34 (Examples 12 and 13) having a size of 0.75 mm was prepared. The length of the slit 42 is set to 0 mm, 5 mm, 10 mm, 15 mm, and 20 mm with respect to the inner wall portion 34 of Examples 10 and 11, and the length of the slit 42 with respect to the inner wall portion 34 of Examples 12 and 13. Experiments were conducted under the following suction conditions, with the slits set to 10 mm, 15 mm, and 20 mm. In this experiment, a predetermined amount of liquid is injected into the first aerosol flow path 32a defined by the inner wall portion 34 according to Examples 10 to 13 so as to form a columnar shape, and when the liquid is sucked under predetermined conditions, the second aerosol flow The amount of liquid scattered from the road 32b to the tip of the inner wall portion 34 was measured. In Examples 10 to 13, the lengths of the first aerosol flow path 32a and the second aerosol flow path 32b in the first direction were set to 30 mm.

The suction conditions are as follows.
Suction capacity 2400cc / min
Suction time 3 seconds Number of puffs 1 time (Example 11 and Example 13) 5 times (Example 10 and Example 12)
Suction interval 20 seconds N number (sample size) 3
Orientation of tank 30 (angle in the first direction) 45 ° diagonally with respect to the vertical
Liquid composition Glycerin: Propylene glycol: Water = 45:45:10
Liquid injection amount: 20 μl

FIG. 8 is a graph showing the evaluation results of Experimental Example 2. In FIG. 8, the plots of Examples 10 and 11 in which the liquid evacuation portion length is 0 mm show the evaluation results of the inner wall portion 34 having no liquid evacuation portion. When the liquid evacuation portion length was 0 mm, the droplet arrival amount of Example 10 was about 19.2 mg, and when the liquid evacuation portion length was 0 mm, the droplet arrival amount of Example 11 was about 13.3 mg. .. On the other hand, in Examples 10 and 11 having a liquid evacuation portion length of 5 mm, the amount of droplets reached can be reduced as compared with Examples 10 and 11, respectively, in which the liquid evacuation portion length is 0 mm. Specifically, the amount of droplets reached in Example 10 when the length of the liquid evacuation part is 5 mm is about 14.3 mg, and the amount of droplets reached in Example 11 when the length of the liquid evacuation part is 5 mm is about 6. It was 0.4 mg. Therefore, from this experiment, it can be seen that the amount of droplets that reach can be reduced by the presence of the liquid evacuation portion.

The amount of droplets reached from Example 1 to Example 4 having a liquid evacuation portion length of 10 mm was about 2.7 mg, about 1.3 mg, about 3.3 mg, and about 3.6 mg, respectively. Therefore, when the liquid evacuation portion length is 10 mm, the amount of droplets reached can be significantly reduced as compared with the case where the liquid evacuation portion length is 5 mm. The amount of droplets reached from Examples 1 to 4 having a liquid evacuation section length of 15 mm was about 1.2 mg, about 0.7 mg, about 2.8 mg, and about 0.6 mg, respectively. The amount of droplets reached from Examples 1 to 4 of 20 mm was about 1.1 mg, about 0.7 mg, about 0.4 mg, and about 0.5 mg, respectively. Therefore, by setting the length of the liquid evacuation portion to 10 mm or more, the amount of droplets that reach can be further reduced.

Based on the above experimental results, the length of the liquid evacuation section is preferably 10 mm or more and 20 mm or less from the viewpoint of reducing the amount of droplets reached. In other words, the ratio of the length of the liquid evacuation portion (slit 42) in the first direction to the length (30 mm) of the first aerosol flow path 32a and the second aerosol flow path 32b is 1/3 or more and 2/3 or less. Is preferable.

Next, the non-combustion heating type flavor suction device 100 according to another embodiment will be described. Compared with the non-combustion heating type flavor suction device 100 described with reference to FIGS. 1 to 8, the non-combustion heating type flavor suction device 100 according to another embodiment has a liquid holding portion that communicates with the liquid stored in the liquid storage portion. The difference is that the tip of the tank 30 is provided. FIG. 9 is a schematic side sectional view of the tank 30 of the non-combustion heating type flavor suction device 100 according to another embodiment. The tank 30 shown in FIG. 9 may have the same structure as the tank 30 shown in FIG. In the example shown in FIG. 9, the tank 30 is provided with a lid member 50 that covers the upper wall portion 30a at the tip thereof.

FIG. 10A is a perspective view of the lid member 50. FIG. 10B is a plan view of the lid member 50. FIG. 10C is a cross-sectional view taken along the line 10C-10C shown in FIG. 10B. As shown in the drawing, the lid member 50 includes a top plate portion 52 having a substantially rectangular plate shape according to the shape of the tank 30, and a substantially tubular side plate portion 54 extending from the top plate portion 52. An opening 56 is provided in a substantially central portion of the top plate portion 52 so as to communicate with the aerosol flow path 32 of the tank 30 and allow the aerosol from the aerosol flow path 32 to pass through. The opening 56 is formed in the lid member 50 so that the center of the opening 56 substantially coincides with the center of the aerosol flow path 32 of the tank 30 in the second direction when the lid member 50 is attached to the tank 30. .. Further, one or a plurality of ridge portions 58 extending in the second direction are provided on the surface of the top plate portion 52 facing the upper wall portion 30a of the tank 30. As a result, an uneven portion is formed on the surface of the top plate portion 52 facing the upper wall portion 30a of the tank 30. When the lid member 50 is attached to the tank 30, the uneven portion communicates with the liquid evacuation portion of the tank 30.

As shown in FIG. 10B, it is preferable that the ridge portion 58 is configured so that the gap between the ridge portions 58 becomes smaller as the distance from the aerosol flow path 32 (or the opening 56) increases in the second direction. Further, as shown in FIG. 10C, it is preferable that the ridge portion 58 is configured so that the gap between the ridge portions 58 increases as the distance from the top plate portion 52 in the first direction increases. In other words, in the state where the lid member 50 is attached to the tank 30, the gap between the ridges 58 becomes smaller as the ridge 58 moves away from the upper wall 30a (tip) of the tank 30 in the first direction. It is preferable to be configured in. The size of the gap in the second direction of the ridge portion 58 is arbitrary, and may be constant, for example.

As described above, the aerosol can be aggregated on the wall surface of the inner wall portion 34 that defines the aerosol flow path 32, and droplets can be formed in a columnar shape. The columnar droplets move toward the mouthpiece 18 side with the suction of the user's non-combustion heating type flavor suction device 100, and are retracted to the liquid evacuation portion, that is, the flat surface portion 40 or the slit 42. If the use of the non-combustion heating type flavor suction device 100 is further continued, the droplets evacuated to the liquid evacuating portion may reach the tip of the liquid evacuating portion, or the liquid evacuating portion may be filled with the droplets. is there. In this case, the droplet may reach the user's mouth from the liquid evacuation section.

Therefore, in the present embodiment, the lid member 50 is provided with an uneven portion (corresponding to an example of the liquid holding portion) that communicates with the liquid evacuation portion. The droplet that has reached the tip of the liquid evacuation portion is held by the concave-convex portion of the lid member 50 by capillary action. Further, the droplets that have reached the tip of the liquid evacuation portion can be held by the capillary action in the gap between the top plate portion 52 of the lid member 50 and the upper wall portion 30a of the tank 30. As a result, it is possible to prevent the liquid stored in the liquid evacuation unit from reaching the user's mouth. Further, in the present embodiment, as the distance from the aerosol flow path 32 in the second direction increases, the gap between the ridges 58 becomes smaller, so that the liquid separates from the aerosol flow path 32 in the second direction due to the capillary phenomenon. It can promote movement in the direction. Further, in the present embodiment, the gap between the ridges 58 becomes smaller as the distance from the upper wall portion 30a of the tank 30 increases in the first direction, so that the liquid flows from the tank 30 in the first direction due to the capillary phenomenon. It can be promoted to move away.

In the present embodiment, a plurality of ridge portions 58 are provided to form the uneven portion, but the present invention is not limited to this. As long as the uneven portion capable of holding the liquid by capillary action can be formed, the shape thereof is arbitrary, and for example, a plurality of convex portions, a plurality of concave portions, and the like can be adopted. Further, instead of or in addition to the uneven portion, between the top plate portion 52 of the lid member 50 and the upper wall portion 30a of the tank 30, a liquid holding member (liquid holding portion) made of a porous member, fibers, or the like. (Corresponding to one example) can also be provided. The porous member or fiber may include, for example, a cellulose-based non-woven fabric, a glass fiber non-woven fabric, paper, a sponge, a ceramic, a glass porous body, or the like. Further, the lid member 50 may be detachable from the tank 30 by the user, or may be fixed to the tank 30 so as not to be detached.

Further, the uneven portion of the present embodiment is located radially outside the aerosol flow path 32. Therefore, it is possible to prevent the aerosol passing through the aerosol flow path 32 from reaching the uneven portion, and as a result, it is possible to prevent the aerosol from condensing on the uneven portion. Even when a liquid holding member made of a porous member or a fiber or the like is arranged between the top plate portion 52 of the lid member 50 and the upper wall portion 30a of the tank 30, this liquid holding member is radially larger than the aerosol flow path 32. It is preferable to arrange them at positions separated from each other on the outside.

In the present embodiment, a plurality of ridges 58 are provided to form the uneven portion, but the lid member 50 may not include the ridges 58 as long as the liquid can be held by capillary action. FIG. 11 is a schematic side sectional view of a tank 30 provided with a lid member 50 according to another embodiment. The lid member 50 shown in FIG. 11 does not have a ridge portion 58, but the droplets that reach the tip of the liquid storage portion receive a gap (a gap between the top plate portion 52 of the lid member 50 and the upper wall portion 30a of the tank 30). It is held by capillary action) in a liquid holding portion (corresponding to an example). Further, in the illustrated embodiment, the distance between the surface of the top plate portion 52 of the lid member 50 on the tank 30 side and the upper wall portion 30a of the tank 30 becomes smaller as the distance from the aerosol flow path 32 in the second direction increases. , The lid member 50 is formed. As a result, the droplets that have reached the tip of the liquid evacuation portion are first held in a relatively large gap between the top plate portion 52 of the lid member 50 and the upper wall portion 30a of the tank 30. Further, according to the illustrated embodiment, it is possible to promote the movement of the droplet held in the relatively large gap in the second direction by the capillary action so as to be separated from the opening 56.

The distance between the surface of the top plate portion 52 of the lid member 50 on the tank 30 side and the upper wall portion 30a of the tank 30 may be constant. Further, the lid member 50 shown in FIG. 11 may be provided with the ridge portion 58 shown in FIGS. 10A to 10C.

FIG. 12 is a schematic top view of the tank 30 of the non-combustion heating type flavor suction device 100 according to still another embodiment. As shown, one or more ridges 36 are formed on the tip surface of the tank 30. As a result, an uneven portion (corresponding to an example of the liquid holding portion) is formed on the end surface of the upper wall portion 30a of the tank 30 on the distal end side. This uneven portion communicates with the liquid evacuation portion of the tank 30.

As shown in FIG. 12, it is preferable that the ridge portion 36 is configured so that the gap between the ridge portions 36 becomes smaller as the distance from the aerosol flow path 32 in the second direction increases. Further, like the ridge portion 58 shown in FIG. 10C, the ridge portion 36 is preferably configured so that the gap between the ridge portions 36 becomes smaller as the distance from the upper wall portion 30a in the first direction increases. .. The size of the gap between the ridges 36 is arbitrary, and may be constant, for example.

Since the tank 30 has an uneven portion that communicates with the liquid evacuation portion, the droplet that reaches the tip of the liquid evacuation portion is held by the uneven portion of the tank 30 by capillary action. As a result, it is possible to prevent the liquid stored in the liquid evacuation unit from reaching the user's mouth. Further, in the present embodiment, the gap between the ridges 36 becomes smaller as the distance from the aerosol flow path 32 in the second direction increases, so that the liquid separates from the aerosol flow path 32 in the second direction due to the capillary phenomenon. It can promote movement in the direction. Further, when the gap between the ridges 36 becomes smaller as the distance from the tip of the tank 30, that is, the upper wall portion 30a of the tank 30 increases in the first direction, the liquid is released in the first direction due to the capillary phenomenon. It is possible to promote the movement in the direction away from the upper wall portion 30a of the tank 30.

In the present embodiment, a plurality of ridge portions 58 are provided to form the uneven portion, but the present invention is not limited to this. As long as the uneven portion capable of holding the liquid by capillary action can be formed, the shape thereof is arbitrary, and for example, a plurality of convex portions, a plurality of concave portions, and the like can be adopted. Further, instead of or in addition to the uneven portion, a liquid holding member (corresponding to an example of the liquid holding portion) made of a porous member or a fiber or the like may be provided on the upper wall portion 30a of the tank 30. The multi-layer member or fiber may include, for example, a cellulosic non-woven fabric, a glass fiber non-woven fabric, paper, a sponge, a ceramic, a glass porous body and the like. Further, the lid member 50 shown in FIGS. 10A to 10C or 11 may be attached to the tip of the tank 30 shown in FIG.
