The body (T1aa) may protrude outward from the guide (20a). In addition, the body (T1aa) may be formed such that the horizontal width (W1) increases as it goes upward. This body (T1aa) may serve to increase the rigidity of the first-first hook (T1a). The protrusion (T1ab) may protrude upward from the upper surface of the body (T1aa). The protrusion (T1ab) may be a place where the second-first hook (T2a) of the second hook (T2) of the side cover (11a) is caught.

[0124] The first-second hook (T1b) may be located on the lower side of the first outside air inlet (K1). The first-second hook (T1b) may include a body (T1ba) and a protrusion (T1bb) protruding from the body (T1ba). The body (T1ba) may protrude outward from the guide (20a). In addition, the body (T1ba) may be formed such that the horizontal width (W2) increases as it goes downward. This body (T1ba) serves to increase the rigidity of the first-second hook (T1b). The protrusion (T1bb) may protrude downward from the lower surface of the body (T1ba). The protrusion (T1ba) may be a place where the second-second hook (T2b) of the second hook (T2) of the side cover (11a) is caught.

[0125] Fig. 15 is a perspective view of the side cover (23) showing the second hook (T2) of the side cover (23), and Fig. 16 is a side cross-sectional view showing the second hook (T2) of the side cover (23).

[0126] Referring to FIGS. 15 and 16, the second hook (T2) may be arranged in the inner space of the side cover (23). The side cover (23) may be formed so that one side is open and the interior is empty. The second hook (T2) may protrude horizontally from the inner surface of the side cover (23). The second hook (T2) may include a second-first hook (T2a) and a second-second hook (T2b). The second-first hook (T2a) and the second-second hook (T2b) may be arranged to be spaced apart from each other in the vertical direction (z).

[0127] The second-first hook (T2a) may include a body (T2aa) and a protrusion (T2ab) protruding from the body (T2aa). The body (T2aa) may protrude from the inner surface of the side cover (23). The body (T1aa) of the second-first hook (T2a) may be formed in a cantilever shape on the inner surface of the side cover (23) so as to be deformed in the process of contacting the first-first hook (T1a) of the heater body (21). The protrusion (T2ab) may protrude downward from the lower surface of the body (T2aa). The protrusion (T2ab) may be a place where the first-first hook (T1a) of the heater body (21) is caught.

[0128] The 2-2 hook (T2b) may include a body (T2ba) and a protrusion (T2bb) protruding from the body (T2ba). The body (T12ba) may protrude from the inner surface of the side cover (23). The body (T2ba) of the 2-1 hook (T2a) may be formed in a cantilever shape on the inner surface of the side cover (23) so as to be deformed in the process of contacting the 1-1 hook (T1a) of the heater body (21). The protrusion (T2bb) may protrude downward from the lower surface of the body (T2ba). The protrusion (T2bb) may be a place where the 1-2 hook (T1b) of the heater body (21) is caught.

[0129] Meanwhile, the body (T2ba) of the 2-2 hook (T2b) may include a through hole (Ha). The through hole (Ha) penetrates the upper and lower surfaces of the body (T2ba) of the 2-2 hook (T2b), and serves to connect the upper space and the lower space of the 2-2 hook (T2b). In addition, the second outside air inlet (K2) may be arranged on the lower surface of the side cover (23). The second outside air inlet (K2) is connected to the lower space of the 2-2 hook (T2b). In addition, the second outside air inlet (K2) is connected to the through hole (Ha), so that the outside air of the side cover (23) can enter the upper space of the 2-2 hook (T2b) through the second outside air inlet (K2) and the through hole (Ha).

[0130] Fig. 17 is a side cross-sectional view showing a state in which a side cover (23) is connected to a heater body (21).

[0131] Referring to Fig. 17, the 2-1 hook (T2a) may be positioned above the 1-1 hook (T1a). The 2-2 hook (T2b) may be positioned below the 1-2 hook (T1b). When the side cover (23) is coupled to the heater body (21), the protrusion (T2ab) of the 2-1 hook (T2a) may catch the protrusion (T1ab) of the 1-1 hook (T1a), and the protrusion (T2bb) of the 2-2 hook (T2b) may catch the protrusion (T1bb) of the 1-2 hook (T1b).

[0132] When the side cover (23) is connected to the heater body (21) in this way, the inner space of the side cover (23) and the first external air inlet (K1) can be connected.

[0133] Fig. 18 is a cross-sectional view of a heater module (20).

[0134] Referring to FIG. 18, the cover (11a) may include a slide projection (11aa). The slide projection (11aa) may be positioned adjacent to a slot (11ab) of the cover (11a). The slide projection (11aa) may be positioned in a recess (20b) of the heater body (21).

[0135] And the side cover (23) can be placed in the slot (11ab) of the cover (11a). When the heater body (21) moves along the slot (11ab) of the cover (11a), the side cover (23) can move along the slot (11ab).

[0136] Figure 19 is a drawing showing the gap (G) between the side cover (23) and the main body.

[0137] Referring to Fig. 19, a gap (G) may be formed between the main body (10) and the lower end of the side cover (23) in the vertical direction (z). The gap (G) is connected to a second external air inlet (K2). This gap (G) may be used to guide external air to the second external air inlet (K2). As in FL1 of Fig. 19, external air is introduced through the gap (G), and the air introduced through the gap (G) may be introduced into the internal space of the side cover (23) through the second external air inlet (K2).

[0138] Fig. 20 is a drawing showing a side cover (23) protruding from a cover (11a).

[0139] Referring to Fig. 20, the side cover (23) may be positioned to protrude more than the cover (11a) in the width direction (x). This is to hold the heater module (20) when mounting or detaching the heater module (20) to or from the cover (11a). In addition, the horizontal distance (W4) from the outermost side of the side cover (23) in the width direction (x) to the side of the cover (11a) may be equal to or smaller than the horizontal distance (W3) from the outermost side of the cartridge (30) in the width direction (x) to the side of the cover (11a).

[0140] Hereinafter, referring to FIGS. 21 to 27, the path through which outside air enters the heater module (20) and is supplied to the heater (22) will be described in detail.

[0141] Figure 21 is a drawing showing the flow of air flowing into the interior of the heater body (21) through the side cover (23).

[0142] Referring to FIGS. 19 and 21, outside air is introduced through the gap (G), and the air introduced through the gap (G) can be introduced into the internal space of the side cover (23) through the second outside air inlet (K2). As in FL2 of FIG. 21, the air introduced through the second outside air inlet (K2) passes through the through hole (Ha) and is introduced into the internal space of the side cover (23), and the air introduced into the internal space of the side cover (23) can be introduced into the interior of the heater body (21) through the first outside air inlet (K1).

[0143] In this way, the air introduced into the interior of the heater body (21) is ultimately guided to the lower space of the heater (22) as shown in FL6 of FIG. 21, and the specific air flow for this is described with reference to the drawings below.

[0144] Fig. 22 is a plan view of a heater module (20), Fig. 23 is a side cross-sectional view of a heater module (20) based on X1-X1 of Fig. 22, and is a drawing showing the flow of air that flows into the interior of a heater body (21) and is guided to the heater, Fig. 24 is a side cross-sectional view of a heater module housing (21a) of a heater module (20), and Fig. 25 is a perspective view of a heater lower sealing member (21g).

[0145] As illustrated in Fig. 24, the heater module housing (21a) may include a hole (Hb) arranged in an inner partition wall (WA). The hole (Hb) may connect the upper space of the heater module housing (21a) and the lower space of the heater module housing (21a) with respect to the partition wall (WA). The first outside air inlet (K1) may be arranged in the heater module housing (21a) and may be located lower than the partition wall (WA).

[0146] As illustrated in Fig. 25, the lower surface of the heater lower sealing member (21g) may include a hole (Hc). The hole (Hc) may connect the outside and inside of the heater lower sealing member (21g).

[0147] The hole (Hb) of the heater module housing (21a) and the hole (Hc) of the heater lower sealing member (21g) can be aligned.

[0148] As in FL3 of Fig. 23, air introduced into the first outside air inlet (K1) can first pass through the hole (Hb) of the heater module housing (21a). The air that has passed through the hole (Hb) of the heater module housing (21a) can pass through the hole (Hc) of the heater lower sealing member (21g) and flow into the interior of the heater housing (21f). The air introduced into the interior of the heater housing (21f) can be guided to the upper space (M1) formed by the heater lower sealing member (21g) and the heater housing (21f). In this way, the heater body (21) can form a first flow path (U1) including the hole (Hb) of the heater module housing (21a), the hole (Hc) of the heater lower sealing member (21g), and the upper space (M1) formed by the heater lower sealing member (21g) and the heater housing (21f).

[0149] FIG. 26 is a side cross-sectional view of a heater module (20) based on X2-X2 of FIG. 22, and is a drawing illustrating the flow of air that flows into the interior of a heater body (21) and is guided to the heater, and FIG. 27 is a side cross-sectional view of a heater module (20) based on X3-X3 of FIG. 22, and is a drawing illustrating the flow of air that flows into the interior of a heater body (21) and is guided to the heater.

[0150] As in FL4 of Fig. 26, air introduced into the upper space (M1) of the heater lower sealing member (21g) can be introduced into the upper channel (M2) of the heater housing (21f).

[0151] And, as in FL5 of FIG. 27, air introduced into the first upper channel (M2) of the heater housing (21f) can be introduced into the connection channel (M3) of the heater housing (21f).

[0152] Air flowing along the connecting channel (M3) is introduced into the second upper channel (M4) of the heater housing (21f). The air flowing along the second upper channel (M4) can be guided to the lower part of the heater (22) as shown in FL6 of Fig. 21.

[0153] In this way, the side cover (23) serves to guide outside air to the heater (22) in addition to the function of allowing the user to rip it.

[0154] Meanwhile, the main body (10) may include a first flow path (U2) connected to a suction sensor (SS). When the heater module (20) is assembled to the main body (10), the first flow path (U1) and the second flow path (U2) may be connected.

[0155] Figure 28 is a drawing showing the positions of the suction sensor (SS) and the side cover (23).

[0156] Referring to Fig. 28, the suction sensor (SS) can measure the internal pressure of the airflow path inside the heater module (20). The suction sensor (SS) is connected to the first upper channel (M2 of Fig. 26) of the heater housing (21f) and can measure the pressure change of the airflow path under normal conditions and when the user puffs.

[0157] This suction sensor (SS) may be positioned in the main body (10) and may be positioned adjacent to the first outside air inlet (K1) of the heater main body (21). In addition, the suction sensor (SS) may be positioned adjacent to the side cover (23). In particular, the side cover (23) may be positioned to overlap the suction sensor (SS) in the width direction (x). The first outside air inlet (K1) may be positioned so as not to overlap the suction sensor (SS) in the width direction (x).

[0158] In this way, by placing the suction sensor (SS) adjacent to the airflow path formed by the side cover (23), the pressure change inside the airflow path can be detected more precisely.
