When the user inhales through the suction medium 10, a sound pressure is formed in the airflow path 140, and the sound pressure is detected by the sound pressure sensor 150 through a through hole 130 formed at one side of the airflow path 140. Since the sound pressure sensor 150 is electrically connected to the control unit (circuit board) 160, the control unit (circuit board) 160 receives a signal from the sound pressure sensor 150, and as described later, A voltage is applied to the coil heater 280 to allow aerosol to be generated by electrical resistance heating.

In the space inside the housing 102 in which the cartomizer 200 can be detached, the cartomizer elastic means 194 and the cartomizer elastic means 194 are compressed in accordance with the mounting of the cartomizer 200. It further comprises a second lid hook means 192 for fixing the 200 to a mounting position inside the housing 102. As apparent from the comparison of FIGS. 1 and 2, the cartomizer resilient means 194 is located on the upper side of the suction part 110 in the cartomizer 200 mounting space inside the housing 102, and the second lid hook means. 192 is located at the lower side of the second lid 190. The user opens the second lid 190 and pushes the cartomizer 200 into the cartomizer mounting space inside the housing 102 so that the cartomizer elastic means 194 is compressed to close the second lid 190.

As described above, the space inside the pipe 250 provided to the cartomizer 200 may be in communication with the contact communicating unit 142 and the airflow path 140 according to the mounting and detaching of the cartomizer 200. There is a bar.

As can be seen from the cartomizer 200 shown in FIGS. 3 to 5, one side of the cartomizer 200 is provided with a terminal 270 and the cartomizer 200 is pushed into the cartomizer mounting space inside the housing. When inserted and mounted, the terminal 270 is electrically connected to a terminal (not shown) at a corresponding position in the cartomizer mounting space inside the housing. In this case, if the user reverses the surface of the cartomizer body 220 in which the terminal 270 is formed and the surface of the cartomizer body 220 in which the terminal 270 is not formed, and puts it into the cartomizer mounting space inside the housing as described above. Electrical connections will not be made properly. Therefore, in the present invention, the shape of the surface where the terminal 270 is installed in the cartomizer main body 220 (the surface shown in FIG. 4), and the shape of the surface where the terminal 270 is not installed in the cartomizer main body 220 ( The surface shown in FIG. 3) is formed differently, and the shape inside the cartomizer mounting space inside the housing is also configured to correspond thereto. For example, as shown in FIG. 3, protruding rails 224 are formed on both sides of the cartomizer main body 220 in which the terminal 270 is not provided, and the cartomizer main body in which the terminal 270 is installed as shown in FIG. 4. The surface of the 220 may be formed flat without installing it, and the inside of the cartomizer mounting space inside the housing may be configured to correspond thereto. By doing so, when the user intends to change the orientation of the cartomizer 200, the cartomizer 200 cannot be inserted into the cartomizer mounting space inside the housing. This is only described based on the directions of FIGS. 3 and 4 (which are referred to as 'forward and backward directions' for convenience of description), but since the cartomizer 200 has a substantially rectangular parallelepiped shape, there is no possibility of being inverted in the left and right directions. .

As described above, the electrically heated aerosol generator 100 includes a control unit (circuit board) 160 and 170 between the suction unit 110 and the cartomizer 200 side and the battery 180 side. The circuit board) may be divided into upper and lower parts as shown in the drawings as required, may be provided as one, or may be provided in two or more. The control unit (circuit board) 160, 170 is electrically connected to the auxiliary heating unit 112, the pressure reducing sensor 150, the battery 180, and the terminal 270 of the cartomizer, and is electrically connected to these or these. The other components of the control unit may also be electrically connected to the charging and communication terminal 102, and may be used to charge the battery 180 or to transmit or receive signals or communicate with the external heating aerosol generator 100. Alternatively, the control unit (circuit board) 160, 170 may include a wireless transmission / reception module and perform a function according thereto.

3 is a perspective view and an exploded perspective view of the cartomizer 200 that can be used in the electric heating aerosol generator according to an embodiment of the present invention from one side, Figure 4 is a perspective view and an exploded perspective view of FIG. 5 is a cross-sectional view of the cartomizer 200 according to FIGS. 3 and 4.

The cartomizer 200 is largely divided into an upper cover 210, a cartomizer body 220, and a coil bracket assembly 230. These are combined without using an adhesive as described below.

The cartomizer 200 includes a cartridge for storing the liquid phase as described above, and an atomizer for generating an aerosol from the liquid phase. In the present invention, the upper cover 210 and the cartomizer body 220 corresponds to a cartridge, and the coil bracket assembly 230 coupled below may correspond to the atomizer.

The suction part 110 and the airflow path 140 shown in FIGS. 1 and 2 communicate with the pipe 250 provided in the cartomizer body 220 in a straight line. Pipe 250 is formed integrally with the cartomizer body 220 and extends in a straight line into the center of the cartomizer body 220. That is, the cartomizer 200, the hollow body-shaped cartomizer body 220, the pipe 250 is formed integrally in the center, the upper cover 210 is coupled to the upper part of the cartomizer body 220, the cartomizer Is coupled to the lower portion of the main body 220 is made of a coil bracket assembly 230, by the combination of the liquid storage unit 300 is formed inside the cartomizer body 220 and the outside of the pipe 250. The coil bracket assembly 230 is provided with a wick 290 and a coil heater 280 and a structure 240 supporting the same, as described below.

The upper portion of the cartomizer body 220 is provided with a liquid injection hole 226 and a gasket 228 that can open and close it, and an upper cover fastening hook 222 is provided at the upper edge of the cartomizer body 220. As a result, the liquid is injected into the liquid storage unit 300 inside the assembled cartomizer body 220 through the liquid inlet 226 and the liquid inlet 226 is blocked through the gasket 228 to cover the upper cover 310. When coupled to the upper portion of the cartomizer body 220 has a configuration that the plurality of upper cover fastening hook 222 is fitted into the upper cover hole 214 formed in the upper cover 210 to correspond thereto. This makes it possible to close the liquid inlet 226 without using an adhesive. In use, the liquid is turned into aerosols and inhaled by the user, so the use of adhesives in their combination should be avoided.

This configuration has another advantage. If the coupling between the upper cover fastening hook 222 and the upper cover hole 214 is not impossible to release, the user can release the upper cover 210 if necessary. It is also possible to refill the liquid phase after separation and separation of the gasket 228. Of course, depending on the manufacturer's choice, this can be done easily or not so easily by adjusting the bond strength or the strength of the part. In other words, if the manufacturer does not want to recharge or use for other purposes, it may be possible to increase the bonding strength of the upper cover fastening hook 222 so that it is not easily separated or broken and not reused when trying to separate it. There may also be ways to make separation and reassembly easier without the use of tools. What is said in the above description is that the liquid inlet 226, the gasket 228, the upper cover 210 can be bonded without using an adhesive.

As described above, the cartomizer contact connector 212 is provided on the upper cover 210, and the cartomizer contact connector 212 extends inside the cartomizer body 220 while contacting the elastic connector 144 as described above. The pipe 250 provided to be in communication with the airflow path 140 without leakage.

3 to 5 show a detailed configuration of the coil bracket assembly 230 that functions as an atomizer. The coil bracket assembly 230 includes a packing 231, a structure 240, a wick 290, a coil heater 280, a terminal 270, and a lower cover 260. These functions to properly form the wick 290 and the coil heater 280 containing the liquid to the cartomizer body 220 while the liquid is formed as an aerosol without leaking to the outside.

As shown in FIG. 5, in the state where the coil bracket assembly 230 is coupled to the cartomizer body 220, an aerosol generating space 252 is formed at the upper and lower portions of the wick 290, and the space is formed of the cartomizer body 220. It is in direct communication with the space inside the pipe 250 extending in the center. That is, the liquid contained in the wick 290 is changed into an aerosol in the aerosol-forming space 252 by resistance heating of the coil heater 280, and the aforementioned airflow path 140 and the suction unit 110 through the inside of the pipe 250. ), And the user may inhale through the suction medium 10. As is apparent from the configuration of FIGS. 1 to 5, the suction medium 10, the suction part 110, the airflow path 140, the pipe 250, and the aerosol generating space 252 are disposed in the gravity direction, that is, in the downward direction. Therefore, when the user inhales the aerosol through the inhalation medium 10 while holding the hand, there is no great difficulty in inhaling the aerosol generated in the aerosol generating space 252. In order to minimize the suction resistance of the aerosol, a structure hole 246 is provided in the structure 240, and a lower cover hole 264 is provided in the lower cover 260, and they are in communication with the aerosol generating space 252. Of course, a suitable hole is provided in the housing 102 or the second lid 190 to communicate with such a path, so that a series of paths such as the outside space and the above can be communicated. For example, a hole may be provided at a position corresponding to the lower cover hole 264 of the second lid 190. As another example, as shown in FIG. 2, the cartomizer 200 after the second lid 190 is closed. Since a predetermined space may be provided between the lower surface of the lower cover 260 and the second lid 190, a hole may be provided on the side surface of the housing (toward the front or rear side of FIG. 2) to communicate with the predetermined space. You may be.

In addition, as will be described later, the liquid storage unit 300 is provided outside the pipe 250 and is provided inside the cartomizer body 220 so as to be isolated from the path through which the aerosol flows, and thus the liquid storage unit 300 in the inhalation process of the aerosol. There is no problem that the liquid phase stored in the inhalation process is inhaled during the aerosol inhalation process. The liquid phase stored in the liquid storage unit 300 is also in contact with the wick 290 through the liquid supply port 236 which will be described later in the direction of gravity, that is, downward, and inevitably the electric heating aerosol generator 100 Since it should be located close to or in the direction of gravity it is possible to use up to the last amount of the liquid stored in the liquid storage unit 300.

After the packing 231 couples the coil bracket assembly 230 to the cartomizer body 220, the packing 231 prevents leakage of the liquid and prevents mixing of the aerosol with the liquid during use. Specifically, the side packing 232, the central packing 234, the liquid supply port 236, and the packing ribs 238, first, the packing ribs 238 formed in a plurality of lines on the outer surface of the side packing (232) When the packing 231 is coupled to the cartomizer body 220, the liquid phase is prevented from flowing out, and the central packing 234 surrounds the outer circumference of the pipe 250 and coil coil 280 at the wick 290. By defining an aerosol generating space 252 is formed on the wick 290 as a result of the boundary between the region and the non-installed region, the aerosol generating space 252 is separated into the liquid storage unit 300 and the liquid phase stored therein. (See FIG. 5). The packing 231 is coupled to the cartomizer main body 220 by the interference fit, thereby eliminating the possibility that the liquid is contaminated with chemical components such as the adhesive by not using an adhesive in manufacturing the cartomizer 200.

The structure 240 is coupled to the packing 231, the structure 240 including a wick support 242 for supporting the wick 290, on which the wick 290 is placed, and the wick 290 above. One central packing 234 is put on. Since the wick support portion 242 protrudes from both sides of the structure 240, the wick is spaced apart from the bottom surface of the structure 240, and a predetermined space is formed between the wick 290 and the bottom surface of the structure 240 to generate the aerosol described above. It serves as space 252. The structure hole 246 described above is provided at the bottom surface of the structure 240 to allow the aerosol generating space 252 to communicate with the outside as described above. Through the liquid supply port 236, the liquid phase contacts the wick, and the liquid phase stays in the wick.

The coil heater 280 is wound around the wick 290 to achieve electrical resistance heating. Coil heater 280 extends by coil extension 286 and coil extension 286 is electrically connected to terminal 270 in a suitable manner. Suitable methods simply include the coil extension 286 being mounted on a particular portion of the terminal 270 in the form of a leaf spring or beneath a particular portion of the terminal 270. Alternatively, an appropriately shaped fitting portion may be formed in the terminal 270, and the coil extension 286 may be fitted therein, or a soldering method or the like may be used. As will be described later, since the terminal 270 and the coil extension 286 are coupled together while combining the lower cover 260, it is not difficult to electrically connect them, that is, to make contact with each other. It will not be too difficult to keep it going.

As shown in FIGS. 3 and 4, the coil extension part 286 is bent twice at right angles, and the terminal 270 is bent twice at right angles correspondingly, so that the bent bottom portion of the coil extension part 286 is When the coil bracket assembly is assembled while being mounted on the lower portion of the terminal 270 and the bottom surface of the terminal 270 is abutted by the support rib 262 of the lower cover described later, Since the 'head part' is to be pressed in the vertical direction while being placed on the '∪' part of the terminal 270, it is possible to achieve a solid electrical connection between the two.

One side of the structure 240 is provided with a structure coupling protrusion 244 is fitted to the packing coupling hole 248 formed in the packing 231 when the structure 240 is coupled to the packing 231. This enables a firm coupling of the packing 231 and the structure 240.

The lower cover 260 has a lower cover rim 266 that can cover the outer surface of the structure 240, a support rib 262 for supporting the bottom surface of the plate sputtering terminal 270, and the aforementioned structure hole ( A lower cover hole 264 is provided in communication with 246. Due to the presence of the support ribs 262, a predetermined space is formed from the bottom surface of the lower cover 260 even when the leaf spring-shaped terminal 270 is mounted, and the space is formed through the structure hole 246. 262 and the lower cover hole 264 again.

As shown in FIGS. 3 and 4, two lower cover coupling protrusions 268 are provided at both sides of the lower cover 260 to couple the coil bracket assembly 230 to the cartomizer body 220. It is inserted into the body coupling hole 269 formed in the cartomizer body 220 to ensure a firm coupling between them. As can be seen in the figure, the main body coupling hole 269 is formed in the position and the number of fitting the lower cover coupling protrusion 268. As such, there is no use of any adhesive in the coupling of the cartomizer 200, and since various components are made only by interference fitting and protrusion / hole coupling, the liquid is stored as a raw material of the aerosol to be inhaled by the user and the aerosol is The safety of the generated cartomizer can be improved.

The terminal support part 272 and the terminal hole 274 are provided on the surface of the cartomizer main body 220 shown in FIG. When the coil bracket assembly 230 is coupled to the cartomizer body 220, the bent end of the leaf spring-shaped terminal 270 slides on the terminal support 272 and enters the terminal hole 274, and at the same time, The lower cover coupling protrusion 268 is fitted into the main body coupling hole 269, so that the coupling between the cartomizer body 220 and the coil bracket assembly 230 may be securely performed.

The terminal support part 272 supports the terminal 270 and when the cartomizer 200 is pushed and mounted into the cartomizer mounting space inside the housing as described above, the terminal 270 is the cartomizer mounting space inside the housing. Is electrically connected to a terminal (not shown) at the corresponding position of the. In this regard, the reason why the surface of the cartomizer body 220 is formed differently from the surface on which the terminal is installed is as described above.
