(2) Second Embodiment The cartridge in the second embodiment of the present invention is the cartridge of the first embodiment, wherein the liquid holding portion and the flow portion are in communication.

(3) Third Embodiment The cartridge in the third embodiment of the present invention is the cartridge of the first embodiment, wherein the liquid holding section and the flow section are separated.

(4) Fourth Embodiment The cartridge in the fourth embodiment of the present invention is the cartridge of the third embodiment, wherein the inside of the tank is provided with an extension portion that extends axially forward from the axial rear end to the inside of the collector, and the flow portion is formed including a gap between the outer wall of the extension portion inserted into the inside of the collector and the inner wall of the collector in the portion into which the extension portion is inserted.

(5) Fifth Embodiment The cartridge in the fifth embodiment of the present invention is any of the cartridges of the first to fourth embodiments, wherein a cap is attached to seal the axial front side of the tank.

According to the present invention, in a direct-liquid cartridge used in a non-combustion type suction device, leakage of the liquid in the tank to the outside of the cartridge is suppressed.

The non-combustion type suction device 10 in this embodiment will be described with reference to the drawings. In the following description, "front side" refers to one side of the non-combustion type suction device 10 that faces the heating unit 60 (described later) in the axial direction, and "rear side" refers to the other side that faces the mouthpiece 20 (described later).

(First embodiment)
(Non-combustion type suction device 10)
The non-combustion type inhaler 10 allows the user to enjoy the flavor of tobacco leaves by inhaling an aerosol atomized by heating through an inhalable material 26 (see Figure 2(B)), such as tobacco leaves.

Figure 1(A) is a front view of the non-combustion type suction device 10, and Figure 1(B) is a cross-sectional view taken along line I-I in Figure 1(A). As shown in Figures 1(A) and (B), the non-combustion type suction device 10 comprises a mouthpiece 20, a cartridge 40, and a heating unit 60.

Figure 2(A) is a front view of the mouthpiece 20, Figure 2(B) is a cross-sectional view taken along line II-II of Figure 2(A), Figure 2(C) is a front view of the cartridge 40, Figure 2(D) is a cross-sectional view taken along line III-III of Figure 2(C), Figure 2(E) is a front view of the heating unit 60, and Figure 2(F) is a cross-sectional view taken along line IV-IV of Figure 2(E). Each component will be described in detail below.

(Mouthpiece 20)
The mouthpiece 20 is the part that is sucked by the user.
As shown in Figures 2(A) and (B), the mouthpiece 20 includes a suction section 22, a connection section 24, and an aspirated object 26.

(Suction part 22)
As shown in Figure 2(B), the suction section 22 is divided into a front suction section 22B and a rear suction section 22C by a flange-shaped flange section 22A. The front suction section 22B and the rear suction section 22C are formed in a cylindrical shape, with the outer diameter of the front suction section 22B being larger than the outer diameter of the rear suction section 22C.

Furthermore, a first connecting portion 22D is formed on the front portion 22B of the suction section, closing the front end of the front portion 22B. The first connecting portion 22D is provided with a first through-hole portion 22E, which consists of multiple through-holes extending axially.

(Connection part 24)
As shown in Figure 2(B), the connecting portion 24 includes a cylindrical connecting portion body 24A. Inside this connecting portion body 24A, a second connecting portion 24B is formed, separating the inside of the connecting portion 24 front to back. The second connecting portion 24B is provided with a second through portion 24C, which consists of a plurality of through holes that penetrate in the axial direction.

The connection section 24 is connected to the suction section 22 by press-fitting the suction section 22 into the space on the rear side of the second connecting section 24B, and to the cartridge 40 by press-fitting the cartridge 40 into the space on the front side of the second connecting section 24B.

(Aspirate 26)
The suction material 26 shown in Figure 2(B) is made up of tobacco leaves or the like. The suction material 26 is installed on the rear side of the second connecting portion 24B and is held in place between the first connecting portion 22D and the second connecting portion 24B of the press-fitted suction portion 22.

(Cartridge 40)
The cartridge 40 is the part that stores the liquid aerosol source (hereinafter simply referred to as "liquid") and atomizes this liquid.
As shown in Figure 2(C), the cartridge 40 comprises a cylindrical tank 42 and a cap 44 as its external structure.

(Tank 42)
As shown in Figure 2(D), the tank 42 comprises an outer surface portion 42A that constitutes the outer surface of the tank 42, and a cylindrical extension portion 42B that extends from approximately the radial center portion at the rear end of the outer surface portion 42A toward the front side of the interior of the outer surface portion 42A.

Furthermore, a collector 80 is positioned in the front portion of the interior of the outer surface portion 42A, with multiple disc-shaped blades arranged axially to form a comb-like cross-section. Details of the collector 80 will be described later, but the collector 80 has a blade portion 84 composed of multiple disc-shaped blades on the outer circumferential surface of a cylindrical portion 82. The front end of the extension portion 42B is inserted into the interior of the cylindrical portion 82. In this first embodiment, the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82 into which the extension portion 42B is inserted are in contact. In other words, in the first embodiment, no gap is formed between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82.

Furthermore, the tank 42 stores liquid in the space between the collector 80 and the rear end of the outer surface portion 42A. In this case, no impregnating material such as cotton is placed in the aforementioned space; the liquid is stored directly.

Here, a porous material 30 capable of holding liquid is attached to the front side of the wing portion 84 of the collector 80. As will be described in detail later, the liquid stored inside the tank 42 flows through the porous material 30, and the porous material 30 holding the liquid is heated by the heating unit 60, causing the liquid to atomize.

(Cap 44)
As shown in Figure 2(D), the cap 44 seals the front side of the tank 42 by sandwiching the outer surface of the outer surface portion 42A with the inner surface of the cap 44, while a part of the cap 44 is press-fitted into the inside of the cylindrical portion 82.
Details of the tank 42 and collector 80, which are components of the cartridge 40, will be described later using Figures 3 to 5.

(Heat generating unit 60)
The heating unit 60 is the part that heats the porous body 30 by generating heat.
As shown in Figures 2(E) and (F), the heating unit 60 includes a cylindrical outer casing 62. Inside the outer casing 62 are a power supply unit 62A and a heating unit 62B. The heating unit 62B is housed at the rear end of the outer casing 62 and is able to contact the porous body 30 when the heating unit 60 is connected to the cartridge 40. At this time, the heating unit 60 and the cartridge 40 are connected by press-fitting the heating unit 60 from the front side of the cartridge 40 with the cap 44 removed. Details of the power supply unit 62A are not shown in the figures, and a detailed explanation is omitted, but the power supply unit 62A is equipped with various components, including a secondary battery such as a rechargeable battery, as a rechargeable power source.

Although the details of the heat-generating section 62B are not shown in the diagram, for example, the heat-generating section 62B is configured as follows.
The heating element 62B is made of an alloy mainly composed of nickel and chromium, but it is more preferable that it comprises a base material and a carbon-based heating layer provided on the base material, which contains amorphous carbon and a metal or semimetallic compound as a conductivity inhibitor uniformly dispersed in the amorphous carbon. In this case, the carbon-based heating layer may further contain carbon powder uniformly dispersed in the amorphous carbon.

The metal or metalloid compound refers to commonly available metal carbides, metal borides, metal silide, metal nitrides, metal oxides, metal nitrides, metalloid oxides, metalloid carbides, etc. The type and amount of metal or metalloid compound used are appropriately selected depending on the resistance value and shape of the target heating element 62B. It can be used alone or as a mixture of two or more types. However, due to the ease of resistance control, boron carbide, silicon carbide, boron nitride, and aluminum oxide are particularly preferred. Furthermore, to maintain the excellent properties of carbon, the amount used is preferably 70% or less.

Furthermore, when the carbon-based heating layer further contains carbon powder uniformly dispersed in amorphous carbon, examples of carbon powder include carbon black, graphite, and coke powder, but the use of graphite is particularly preferred.

The heat-generating section 62B is not limited to the above configuration, but may also be configured as follows.
The heating element 62B may comprise a base material and a carbon-based heating layer provided on the base material, which contains amorphous carbon and carbon powder uniformly dispersed in the amorphous carbon. In this case as well, examples of carbon powder include carbon black, graphite, coke powder, etc., but the use of graphite is particularly preferred.

(Tank 42 and collector 80)
Figure 3(A) is a perspective view of the cartridge 40 with the cap 44 removed. As shown in Figure 3(A), the collector 80 is located in the front part inside the outer surface 42A. A cylindrical porous body 30 is attached to the front part of the collector 80. The collector 80 is hollow, and its hollow portion constitutes a flow space 50 for the atomized aerosol to flow to the mouthpiece 20.

Figure 3(B) is a view of Figure 3(A) from the front. As shown in Figure 3(B), in the collector 80, a slit 81 is formed on the rear side of the porous body 30, penetrating the wing portion 84 in the axial direction. Details of the slit 81 will be described later, but the porous body 30 and the slit 81 are in contact.

Figure 3(C) is a view of Figure 3(A) from the rear. As shown in Figure 3(C), a hollow extension 42B is provided in the radially central portion at the rear end of the outer surface 42A. The hollow portion of the extension 42B, similar to the hollow portion of the collector 80, constitutes a flow space 50 for circulating the atomized aerosol to the mouthpiece 20.

Figure 4(A) is a perspective view of the tank 42, Figure 4(B) is a view of Figure 4(A) from the front, and Figure 4(C) is a cross-sectional view taken along line V-V in Figure 4(B). As shown in Figures 4(A), (B), and (C), a fitting groove 42C for fitting the collector 80 is formed inside the outer surface portion 42A at a position that radially overlaps with the front end portion of the extension portion 42B.

Figure 5(A) is a perspective view of the collector 80 from the front, Figure 5(B) is a perspective view of the collector 80 from the rear, Figure 5(C) is a view of Figure 5(A) from the front, Figure 5(D) is a view of Figure 5(C) from the radial direction, and Figure 5(E) is a cross-sectional view of Figure 5(C) along line VI-VI.

As shown in Figure 5(D), the collector 80 is equipped with fin portions 84 erected on the outer circumferential surface of the cylindrical portion 82. Of the fin portions 84, the fin located at the front is the front fin 84A, and the fin located at the rear is the rear fin 84B. Furthermore, several fins between the front fin 84A and the rear fin 84B are thin fins 84C. These thin fins 84C are thinner than the front fin 84A and the rear fin 84B. In this case, the gaps between adjacent fins in the fin portion 84 constitute a liquid-holding portion 90 for holding liquid.

Furthermore, the collector 80 has a slit 81 that penetrates the wing portion 84 in the axial direction. The slit 81 extends radially from the outer circumferential surface of each wing of the wing portion 84 to the vicinity of the outer circumferential surface of the cylindrical portion 82. In the first embodiment, the space formed by the slit 81 constitutes a flow section 70 for circulating the liquid stored inside the tank 42 to the porous body 30.

As shown in Figures 5(B) and (D), the slit 81 comprises a wide section 81A formed on the rear end wing 84B, with a wide groove width, and a narrow section 81B formed on the wings of the wings 84 other than the rear end wing 84B, with a narrower groove width than the wide section 81A. The wide section 81A has the function of circulating the liquid stored inside the tank 42 to the porous body 30, and also has the function of replacing the air inside and outside the collector 80. By performing air replacement through the wide section 81A, leakage and dripping of liquid from the porous body 30 due to the liquid inside the tank 42 can be prevented.

As shown in Figures 5(A) to (E), the front end surface of the front wing 84A is provided with a mounting portion 86 that has thickness in the axial direction and is substantially elliptical when viewed from the axial direction. Two through holes are formed in the mounting portion 86, extending axially. Of these two through holes, the one formed on the front side of the slit 81 is the mounting hole 86A into which the porous body 30 is mounted, and the through hole formed in a position continuous with the hollow portion of the cylindrical portion 82 is the continuous hole 86B. Furthermore, a notch 86C is formed on the radially opposite side of the slit 81 in the front wing 84A, extending axially.

(Aerosol distribution routes)
Next, the aerosol flow path in the first embodiment will be described.
First, the non-combustion type suction device 10 energizes the heating element 62B through the power supply unit 62A, causing the heating element 62B to generate heat and heat the porous body 30 that is in contact with the heating element 62B. As a result, the liquid held in the porous body 30 is atomized and becomes an aerosol.

The atomized aerosol flows into the circulation space 50 from the front end of the collector 80, passes through the inside of the cylindrical section 82, and then flows into the extension section 42B. The aerosol that has entered the extension section 42B travels further to the rear of the circulation space 50 and flows into the mouthpiece 20. The aerosol that has entered the mouthpiece 20 passes through the inhaled substance 26 and then flows into the user's mouth. This allows the user to enjoy the flavor of tobacco leaves.

(Effects and Benefits)
The direct-liquid cartridge 40 used in the non-combustion type suction device 10 of the first embodiment comprises a tank 42, a collector 80, and a porous body 30, as described above. The collector 80 is provided with a liquid holding section 90 and a flow section 70.

As a result, in the first embodiment, liquid can be held in the liquid holding section 90, thus preventing liquid from leaking out of the cartridge 40 when internal pressure changes occur. Furthermore, in the first embodiment, the wide section 81A of the slit 81 has the function of replacing air inside and outside the collector 80, allowing air replacement through the wide section 81A, thus preventing liquid leakage and dripping from the porous body 30 due to the liquid inside the tank 42.

Furthermore, in the first embodiment, the cartridge 40 has a liquid holding section 90 and a flow section 70 in communication. Specifically, as shown in Figures 5(A) to (E), a slit 81 is formed by cutting out a part of the disc-shaped wing constituting the wing section 84. Therefore, the space formed by the slit 81 is in communication with the space between adjacent wings in the wing section 84. As a result, in the first embodiment, liquid can be circulated between the liquid holding section 90 and the flow section 70.

Furthermore, the cartridge 40 in the first embodiment is equipped with a cap 44, and when not in use, such as during transport or sale, the front side of the tank 42 can be sealed by attaching the cap 44.

(Second embodiment)
The second embodiment will be described while omitting or simplifying any parts that overlap with the other embodiments.
Figure 6(A) is a perspective view of the cartridge 40 with the cap 44 removed. Figure 6(B) is a view of Figure 6(A) from the front. Figure 6(C) is a cross-sectional view taken along line VII-VII of Figure 6(B).

As shown in Figures 6(A) to (C), the porous body 30 in the second embodiment differs from that in the first embodiment in its shape and placement in the collector 80. Specifically, the shape of the porous body 30 in the second embodiment differs from that of the first embodiment, which was cylindrical (see Figure 3(A)), in that it is cylindrical. Furthermore, unlike the first embodiment, where the axis of the collector 80 and the axis of the porous body 30 were at different positions (see Figure 3(A)), the porous body 30 in the second embodiment is positioned so that the axis of the collector 80 and the axis of the porous body 30 are approximately coincident.
Furthermore, in the second embodiment, the collector 80 has a mounting portion 86 formed in a cylindrical shape, and the mounting portion 86 has a mounting hole 86A that is approximately the same diameter as the outer diameter of the porous body 30.

(Aerosol distribution routes)
Next, the aerosol flow path in the second embodiment will be described.
The atomized aerosol flows into the collector 80 through the porous body 30, passes through the cylindrical portion 82, and then flows into the extension portion 42B. The aerosol that has flowed into the extension portion 42B moves further to the rear of the flow space 50 and flows into the mouthpiece 20. The aerosol that has flowed into the mouthpiece 20 passes through the inhaled substance 26 and then flows into the user's mouth. This allows the user to enjoy the flavor of tobacco leaves.

As described above, in the second embodiment, since the axis of the cylindrical porous body 30 and the axis of the collector 80 are substantially aligned, the porous body 30 itself constitutes a flow space 50 for circulating the atomized aerosol to the mouthpiece 20, thereby enabling smooth circulation of the atomized aerosol.

(Third embodiment)
The third embodiment will be described while omitting or simplifying any parts that overlap with the other embodiments.
Figure 7(A) is a perspective view of the cartridge 40 with the cap 44 removed. Figure 7(B) is a view of Figure 7(A) from the front. Figure 7(C) is a cross-sectional view taken along line VIII-VIII in Figure 7(B).

In the third embodiment, the collector 80 differs from that in the first and second embodiments in the location where the flow section 70 is formed.
As shown in Figure 7(C), in the third embodiment, the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82 into which the extension portion 42B is inserted are spaced apart. In other words, in the third embodiment, a gap is formed between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82. Also, in the third embodiment, the outer circumferential surface of the porous body 30 and the inner circumferential surface of the cylindrical portion 82 are spaced apart, and a gap is formed between the outer circumferential surface of the porous body 30 and the inner circumferential surface of the cylindrical portion 82.

Furthermore, as shown in Figure 7(C), in the third embodiment, the slit 81 is formed from the rear end wing 84B to immediately after the front end wing 84A. That is, in the third embodiment, the slit 81 is not formed in the front end wing 84A and does not penetrate the wing portion 84 axially. Therefore, in the third embodiment, it is not possible to directly circulate the liquid through the slit 81 into the porous body 30. In the third embodiment, by performing air replacement through the slit 81, it is possible to prevent liquid leakage and dripping from the porous body 30 due to the liquid in the tank 42.

As described above, in the third embodiment, the gap formed between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82 constitutes a flow section 70 for circulating the liquid stored inside the tank 42 into the porous body 30. Furthermore, in the third embodiment, as described above, the liquid-holding portion 90, which is the gap between adjacent blades, and the flow section 70 are separated. This prevents direct flow of liquid from the liquid-holding portion 90 to the flow section 70 in the third embodiment.

Furthermore, in the third embodiment, the collector 80 has a narrower contact range with the heat-generating portion 62B of the porous body 30 compared to the first and second embodiments.
As shown in Figures 7(A) and (B), in the third embodiment, two covering portions 86D are provided, which are approximately crescent-shaped when viewed from the axial direction. The covering portions 86D cover the front end surface of the mounting portion 86 and a part of the porous body 30. As a result, in the third embodiment, the portion of the porous body 30 not covered by the covering portions 86D becomes the contact portion with the heating portion 62B.

(Aerosol distribution routes)
Next, the aerosol distribution path in the third embodiment will be described.
In the third embodiment, the liquid stored inside the tank 42 flows to the porous body 30 through the flow section 70, which is a gap formed between the outer circumferential surface of the extension 42B and the inner circumferential surface of the cylindrical portion 82. When the porous body 30 is heated by the heating section 62B, the liquid held in the porous body 30 is atomized and becomes an aerosol.

The atomized aerosol flows through the porous body 30 into the extension section 42B. The aerosol that has entered the extension section 42B travels further to the rear of the flow space 50 and flows into the mouthpiece 20. The aerosol that has entered the mouthpiece 20 passes through the inhaled substance 26 and then flows into the user's mouth. This allows the user to experience the flavor of tobacco leaves.

Furthermore, in the third embodiment, similar to the second embodiment, the porous body 30 itself constitutes a flow space 50 for circulating the atomized aerosol to the mouthpiece 20, thereby enabling smooth circulation of the atomized aerosol.

(Fourth embodiment)
The fourth embodiment will be described while omitting or simplifying any parts that overlap with the other embodiments.
Figure 8(A) is a perspective view of the cartridge 40 with the cap 44 removed. Figure 8(B) is a view of Figure 8(A) from the front. Figure 8(C) is a cross-sectional view of Figure 8(B) taken along line IX-IX.

The structure of the cartridge 40 in the fourth embodiment is basically the same as that of the second embodiment, but the structure of the collector 80 is slightly different.
In the fourth embodiment, as shown in Figure 8(C), the slit 81 is formed from the rear end wing 84B to immediately behind the front end wing 84A, but not on the front end wing 84A. In other words, in the fourth embodiment, unlike the second embodiment, the slit 81 does not penetrate the wing portion 84 in the axial direction. As a result, in the fourth embodiment, the slit 81 cannot be seen in Figures 8(A) and (B). Therefore, in the fourth embodiment, it is not possible to directly circulate liquid through the slit 81 into the porous body 30. Furthermore, in the fourth embodiment, by performing air replacement through the slit 81, it is possible to prevent liquid leakage and dripping from the porous body 30 due to the liquid in the tank 42.

Furthermore, as shown in Figure 8(C), in the fourth embodiment, the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82 into which the extension portion 42B is inserted are separated. In other words, in this case, a gap is formed between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82.

As described above, in the fourth embodiment, the gap formed between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the cylindrical portion 82 constitutes a flow section 70 for circulating the liquid stored inside the tank 42 into the porous body 30. Furthermore, in the fourth embodiment, as described above, the liquid-holding portion 90, which is the gap between adjacent blades, and the flow section 70 are separated. This prevents direct flow of liquid from the liquid-holding portion 90 to the flow section 70 in the fourth embodiment.

(Aerosol distribution routes)
Next, the aerosol distribution path in the fourth embodiment will be described.
In the fourth embodiment, the liquid stored inside the tank 42 flows to the porous body 30 through the flow section 70, which is a gap formed between the outer circumferential surface of the extension 42B and the inner circumferential surface of the cylindrical portion 82. When the porous body 30 is heated by the heating section 62B, the liquid held in the porous body 30 is atomized and becomes an aerosol.
The flow after the liquid is atomized is the same as in the second embodiment, so the explanation will be omitted.

(Fifth embodiment)
The fifth embodiment will be described while omitting or simplifying any parts that overlap with the other embodiments.
Figure 9(A) is a perspective view of the cartridge 40 with the cap 44 removed. Figure 9(B) is a view of Figure 9(A) from the radial direction. Figure 9(C) is a view of Figure 9(A) from the front. Figure 9(D) is a view of Figure 9(A) from the rear. Figure 9(E) is a cross-sectional view of Figure 9(C) taken along line X-X.

In the fifth embodiment, the collector 80 differs from the first to fourth embodiments in the location where the flow section 70 is formed. In the first to fourth embodiments, the space formed by the slit 81 that penetrates the wing portion 84 axially, or the gap between the outer circumferential surface of the extension portion 42B and the inner circumferential surface of the collector 80, formed the flow section 70. In contrast, as shown in Figure 9(E), in the fifth embodiment, the hollow portion of the cylindrical portion 82 forms the flow section 70. In other words, in the fifth embodiment, the liquid in the tank 42 flows through the hollow portion of the cylindrical portion 82 to the porous body 30.

Furthermore, unlike the first to fourth embodiments, the collector 80 in the fifth embodiment does not have an extension 42B inside the outer surface 42A. This allows for a wider space between the collector 80 and the rear end of the outer surface 42A for storing liquid. Therefore, the cartridge 40 in the fifth embodiment can store more liquid in the tank 42 compared to the first to fourth embodiments.

Furthermore, in the fifth embodiment, the cartridge 40 differs from the first to fourth embodiments in the location where the flow space 50 for circulating the atomized aerosol to the mouthpiece 20 is formed. In the first to fourth embodiments, the flow space 50 was formed along the axis of the cartridge 40, but in the fifth embodiment, the flow space 50 is formed at a position away from the axis of the cartridge 40.

As shown in Figures 9(C) and (D), the outer surface portion 42A in the fifth embodiment is formed in a substantially cylindrical shape with one radially thicker side. As shown in Figure 9(E), the outer surface portion 42A is provided with a first space portion 42D that is open at the front end and closed at the rear end. The first space portion 42D is filled with liquid, and a collector 80 is mounted on the front side. In the fifth embodiment, the porous body 30 mounted on the collector 80 is formed in a cylindrical shape similar to that of the first embodiment.

Furthermore, as shown in Figure 9(E), a second space 42E is provided in the thick portion of the outer surface 42A, which is a through-hole space that penetrates the outer surface 42A in the axial direction and has a roughly triangular shape when viewed from the axial direction (see Figures 9(C) and (D)). This second space 42E constitutes a flow space 50 for circulating the atomized aerosol to the mouthpiece 20.
Furthermore, as shown in Figure 9(E), the outer surface portion 42A in the fifth embodiment is provided with a groove portion 42F formed to connect from approximately the radial center of the rear end portion to the second space portion 42E.

(Aerosol distribution routes)
Next, the aerosol distribution path in the fifth embodiment will be described.
In the fifth embodiment, the liquid stored inside the tank 42 flows through the flow section 70, which is the hollow portion of the cylindrical section 82, to the porous body 30. When the porous body 30 is heated by the heating section 62B, the liquid held in the porous body 30 is atomized and becomes an aerosol.

The atomized aerosol moves radially outward and flows into the second space 42E. The aerosol that flows into the second space 42E moves to the rear side of the flow space 50 and reaches the rear end of the outer surface 42A. The aerosol that reaches the rear end of the outer surface 42A flows into the mouthpiece 20 through the second space 42E or the groove 42F. The aerosol that flows into the mouthpiece 20 passes through the inhaled substance 26 and then flows into the user's mouth. This allows the user to enjoy the flavor of tobacco leaves.

(Sixth embodiment)
The sixth embodiment will be described while omitting or simplifying any parts that overlap with the other embodiments.
Figure 10(A) is a perspective view of the collector 80 from the front, Figure 10(B) is a perspective view of the collector 80 from the rear, Figure 10(C) is a view of Figure 10(A) from the front, Figure 10(D) is a view of Figure 10(C) from one side in the radial direction, Figure 10(E) is a view of Figure 10(C) from the other side in the radial direction, and Figure 10(F) is a cross-sectional view of Figure 10(C) along line XI-XI.

The structure of the cartridge 40 in the sixth embodiment is basically the same as that of the first embodiment, but the structure of the collector 80 is slightly different.
As shown in Figures 10(A), (B), (D), and (F), the collector 80 in the sixth embodiment is provided with a partition wall 88 extending radially from the outer circumferential surface of the cylindrical portion 82. This partition wall 88 is provided on the rear side of the mounting hole 86A.

The partition wall 88 is provided with a flow slit 83 formed to penetrate axially through approximately the central portion of the partition wall 88 in the width direction. In the sixth embodiment, the space formed by the flow slit 83 constitutes a flow section 70 for circulating the liquid stored inside the tank 42 to the porous body 30.
Here, unlike the slit 81 in the first embodiment, the flow slit 83 has only the function of allowing liquid to flow through the porous body 30 and does not have the function of replacing air.

As shown in Figures 10(B) and (E), in the collector 80, an air displacement slit 85 with a wider groove width than the flow slit 83 is provided on the radially opposite side of the flow slit 83. The air displacement slit 85 is formed in the axial direction from the rear end wing 84B to immediately behind the front end wing 84A. That is, the air displacement slit 85 is not formed on the front end wing 84A. Furthermore, the air displacement slit 85 is formed in the radial direction from the outer circumferential surface of each wing of the wing portion 84 to the vicinity of the outer circumferential surface of the cylindrical portion 82. In the sixth embodiment, the air displacement slit 85 has the function of replacing the air inside and outside the collector 80, and by performing air replacement through the air displacement slit 85, it is possible to prevent liquid leakage and dripping from the porous body 30 due to the liquid in the tank 42.

Figure 11(A) is a perspective view of the cartridge 40 with the cap 44 removed. Figure 11(B) is a front view of Figure 11(A). Figure 11(C) is a cross-sectional view taken along line XII-XII in Figure 11(B).
As shown in Figure 11(C), in the sixth embodiment, since a partition wall 88 is provided, even if the cartridge 40 is cut at the same position as in the first embodiment, the wing portion 84 cannot be seen on the far side of the flow slit 83.

The aerosol flow path in the sixth embodiment is the same as in the first embodiment, therefore its explanation is omitted.
