Referring to fig. 5, the partition wall 122 of the pipe portion 120 may partition the insertion space 124 and the coupling space S. The partition wall 122 may be disposed between the insertion space 124 and the coupling space S. The partition wall 122 may extend vertically.

The cartridge 300 may include a first chamber C1. The first chamber C1 may store a liquid. The cartridge 300 may include a second chamber C2. The second chamber C2 may be separated from the first chamber C1. The second chamber C2 may be disposed below the first chamber C1.
The core 311 may be disposed in the second chamber C2. The core 311 may be connected to the first chamber C1. The wick 311 may receive liquid from the first chamber C1. The heater 312 may be disposed in the second chamber C2. The heater 312 may be wound around the core 311. The heater 312 may receive power from the battery 10 (refer to fig. 1). The heater 312 may heat the core 311. When the heater 312 heats the wick 311 supplied with the liquid, aerosol may be generated in the second chamber C2.
The cartridge 300 may have a first inlet 3011. The first inlet 3011 may be formed by opening one side of the upper surface 322 of the cartridge 300. The first inlet 3011 may be formed at a position offset from the first chamber C1 in the vertical direction.
The cartridge 300 may have a second inlet 3012. The second inlet 3012 may be formed by opening one side of the second chamber C2, and may communicate with the second chamber C2.
Cartridge 300 may include an inflow channel 302. The inflow channel 302 may be positioned between the first and second inlets 3011, 3012. The inflow channel 302 may connect the first and second inlets 3011, 3012. The inflow channel 302 may extend longer in the vertical direction. The inflow channel 302 may be formed in parallel with the first chamber C1.
The cartridge 300 may have an outlet 303. The outlet 303 may be formed by opening the second chamber C2. The outlet 303 may communicate the exterior of the cartridge 300 with the second chamber C2. The outlet 303 may be positioned to face the second inlet 3012 with respect to the second chamber C2. When the cartridge 300 is coupled to the tube portion 120, the outlet 303 may be connected to the connection channel 123. The outlet 303 may communicate the connection passage 123 with the second chamber C2. The discharge port 323a forming the outlet 303 may protrude from one side of the cartridge 300. When the cartridge 300 is coupled to the pipe portion 120, the discharge port 323a may be inserted into one end of the connection passage 123.
The extension 140 may be formed to extend to one side from an upper portion of the pipe portion 120. The upper surface 322 of the cartridge 300 may be covered by the extension 140. The lower surface 141 of the extension 140 may face the upper surface 322 of the cartridge 300. The lower surface 141 of the extension 140 may cover the first inlet 3011 and the perimeter of the first inlet 3011. A gap 146 may be formed between the lower surface 141 of the extension 140 and the first inlet 3011 and between the lower surface 141 of the extension 140 and the upper surface 322 of the cartridge 300. Gap 146 may be in communication with first inlet 3011. Gap 146 may be in communication with sensing bore 144.
The sensor 143 may be mounted inside the extension 140. The sensor 143 may be disposed between the lower surface 141 and the upper surface 142 of the extension 140. Sensor 143 may sense ambient airflow. As air flows into the inlet 3011, the sensor 143 may sense the flow of air. The sensor 143 may be a pressure sensor. The sensor 143 may sense the flow of air through a change in ambient pressure. The sensor 143 may be mounted on a substrate 145 disposed inside the extension 140, and may be electrically connected to the controller 20 (refer to fig. 1).
The sensing hole 144 may be formed by opening the lower surface 141 of the extension 140. The sensing hole 144 may be formed at a position corresponding to the sensor 143. The sensing bore 144 may communicate the gap 146 with the sensor 143. The sensor 143 may sense a change in the air pressure in the sensing hole 144 such that the control unit 20 (refer to fig. 1) determines that air flows into the first inlet 3011.
Air may flow from gap 146 to first inlet 3011. Air introduced into the first inlet 3011 may sequentially pass through the inflow channel 302 and the second inlet 3012 to be introduced into the second chamber C2. The air introduced into the second chamber C2 may be discharged to the outside of the cartridge 300 through the outlet 303 along with the aerosol generated near the core 311. The air discharged through the outlet 303 may be supplied to the insertion space 124 and the stick 400 inserted into the insertion space 124 through the connection passage 123.
Referring to fig. 5 to 7, the lower surface 141 of the extension 140 may include an inclined surface 1411. The inclined surface 1411 may be inclined from the end toward the tube portion 120 such that the interval from the cartridge 300 is gradually narrowed. Thus, gap 146 may become progressively narrower as it approaches tube portion 120. The inclined surface 1411 may be inclined to extend from the upper side toward the lower side toward the pipe portion 120 from one end of the inclined surface 1411.
The lower surface 141 of the extension 140 may include a planar surface 1412. The planar surface 1412 may extend from an end of the inclined surface 1411 adjacent the tube portion 120 to the tube portion 120. The planar surface 1412 may extend horizontally to the upper surface 322 of the cartridge 300.
Accordingly, it may be easier to insert the cartridge 300 into the coupling space S to couple it with the main body 100. The inclined surface 1411 may guide the cartridge 300 such that the cartridge 300 is inserted into the coupling space S. When the cartridge 300 is inserted into the coupling space S, even though the cartridge 300 is in contact with the extension 140, the cartridge 300 is in contact with the inclined surface 1411 and slides to guide the coupling space S. The cartridge 300 may be guided to the coupling space S by the inclined surface 1411 and coupled with the coupling 125 (see fig. 3).
Referring to fig. 8, based on the vertical direction, a first distance t1 of gap 146 from inclined surface 1411 to upper surface 322 of cartridge 300 is from planar surface 1412 to cartridge 300. Which may be greater than the second distance t2 of gap 146 to upper surface 322. The first inlet 3011 formed on the upper surface 322 of the cartridge 300 may be located below the inclined surface 1411. The first inlet 3011 may be located in a position that is not aligned with the planar surface 1412 relative to vertical.
Accordingly, resistance to air flowing from the gap 146 to the first inlet 3011 can be reduced, and air can be introduced into the first inlet 3011 more smoothly. Further, the liquid droplets leaking from the cartridge 300 can be prevented from flowing into the sensor 143 through the sensing hole 144.
The sensing aperture 144 may be formed by opening the planar surface 1412. The sensing bore 144 may be in communication with the gap 146. The sensor 143 may be disposed at a position corresponding to the sensing hole 144. The sensor 143 may sense a change in the air pressure of the sensing hole 144. As air flows from gap 146 to first inlet 3011, the change in air pressure may be greater at gap 146 between planar surface 1412 and upper surface 322 of cartridge 300 than at gap 146 between inclined surface 1411 and upper surface 322 of cartridge 300. Therefore, the sensitivity and accuracy of the sensor 143 can be improved.
Therefore, the coupling of the cartridge 300 is convenient, air can be smoothly introduced into the inside of the cartridge 300, and the accuracy of the sensor 143 can be maintained or improved.
Referring to fig. 9, the first inlet 3011 may be formed by opening an upper surface 322 of the cartridge 300. The first inlet 3011 may be disposed above the first chamber C1. The first inlet 3011 may be located below the planar surface 1412. The sensing aperture 144 may be formed by opening the planar surface 1412. The first inlet 3011 may face the sensing aperture 144 formed in the planar surface 1412.
The inflow channel 302 may include a first inflow channel 3021 and a second inflow channel 3022. One end of the first inflow passage 3021 may be connected to the first inlet 3011. The first inflow passage 3021 may extend left and right above the first chamber C1. The first inflow channel 3021 may extend from the first inlet 3011 to the second inflow channel 3022. The second inflow passage 3022 may extend vertically along a lateral portion of the first chamber C1. An upper end of the second inflow channel 3022 may be connected to the other end of the first inflow channel 3021. Air may flow from the gap 146 through the first inlet 3011, the first inflow channel 3021, and the second inflow channel 3022 in this order.
Thus, as air flows from gap 146 into first inlet 3011, the change in air pressure of sensing bore 144 may be greater. Further, the coupling of cartridge 300 may be convenient and may improve the sensitivity and accuracy of sensor 143.
Referring to fig. 10 and 11, the lower surface 141 of the extension 140 may include a flat surface 1412 and an inclined surface 1411. The inclined surface 1411 may be formed at a position corresponding to the first inlet 3011, and the flat surface 1412 may be formed at a position corresponding to the first chamber C1. Gap 146 may be formed between inclined surface 1411 and upper surface 322 of cartridge 300. The spacing of gap 146 between inclined surface 1411 and upper surface 322 of cartridge 300 is greater than the spacing between gap 146 between planar surface 1412 and upper surface 322 of cartridge 300.
The sensing aperture 144 may be formed in the planar surface 1412 and may be adjacent to the inclined surface 1411. Alternatively, the sensing hole 144 may be formed in the inclined surface 1411. The first inlet 3011 may be formed below the inclined surface 1411. The sensing bore 144 and the first inlet 3011 may face each other. The inclined surface 1411 may direct air to flow into the sensing bore 144 and the first inlet 3011.
Accordingly, air can be smoothly introduced into the cartridge 300, and the sensitivity and accuracy of the sensor 143 can be improved.
Referring to fig. 11 and 12, layer 147 may block sensing orifice 144. Layer 147 may be disposed between sensing orifice 144 and sensor 143. Layer 147 may be in contact with the sensing portion of sensor 143. Layer 147 may be breathable. Layer 147 may be a porous layer. Air a may pass through layer 147. As air is introduced into the first inlet 3011 from the gap 146, ambient air passes through the layer 147 and changes in air pressure around the sensing orifice 144 may increase.
Therefore, in order to improve mountability of the cartridge 300, the inclined surface 1411 is formed, and even if a change in the ambient air pressure is reduced due to an increase in the size of the gap 146, the sensitivity and accuracy of the sensor 143 can be improved.
Layer 147 may be a film having waterproof properties. Each of the plurality of holes 1474 formed in the layer 147 has a size sufficient to allow the air a to pass therethrough, but may be formed as particles smaller than the liquid B. For example, layer 147 may be a membrane that selectively allows certain components to pass therethrough. For example, layer 147 may be a GORE-TEX film.
Thus, air a passes through layer 147, but liquid B layer 147 may prevent liquid from passing through layer 147 and into sensor 143. Further, malfunction of the sensor 143 caused by liquid in the air flowing into the sensor 143 and accumulated can be prevented.
