In general, an electronic cigarette refers to an electronic device made to inhale a solution containing nicotine filled in a replaceable cartridge into an aerosol or gaseous state (atomized state).

Such electronic cigarettes can satisfy the desire to smoke in place of regular cigarettes, and do not contain harmful ingredients such as tar, thereby reducing the harmful effects on the human body caused by cigarettes. At the same time, they do not cause the indirect damage of smoking. Due to its advantages, the number of users is increasing explosively. In other words, electronic cigarettes allow smoking indoors and have the same effect as smoking cigarettes while preventing the damage caused by cigarettes that cause various diseases.

In particular, in recent years, electronic cigarettes have been released that allow users to enjoy a variety of flavors by adding other flavors, such as fruit, to the taste of cigarettes.

In these electronic cigarettes, when an atomizer containing liquid nicotine is connected to the battery unit, the heating element of the atomizer generates heat and creates a haze that vaporizes the liquid nicotine.

However, the atomizer used in the electronic cigarette of the prior art uses a ceramic moisture absorber. If a metal heating element is sintered during sintering of the ceramic moisture absorber, there is a possibility that the heating element may be burned due to high temperature. There is a problem that the electrical characteristics may change.

The heater unit 380 includes a heater unit 382 that generates heat energy, and electrical connection lines 384a and 384b for applying power to the heater unit 382 from the control device. The heater unit 382 applies heat energy by contacting the central bottom surface of the lower moisture absorber 212, and perforations or pores in the vertical direction may be formed. The area of the upper side of the heater unit 382 is smaller than the area of the lower moisture absorber 212. An aerosol is generated at the bottom of the porous moisture absorbent 210 in contact with or adjacent to the upper side of the heater unit 382.

The lower case 400 is detachably coupled to the bottom of the outer case 310, has a control device in the inner space, and is provided with an inflow airflow conduit 420 that communicates the external space with the vertical through hole 322a. .

In Figure 2 (a), the upper cover unit 100 and the porous hygroscopic cartridge 200 are combined, and the porous hygroscopic cartridge is in the insertion space (S2) and the insertion groove (S3) of the upper case 300. This is before (200) is inserted. At this time, the non-vertical through hole 344 maintains its shape (basic form) in an uncompressed state, and the height of the elastic portion 340 is (D1).

In Figure 2 (b), the upper cover unit 100 and the porous moisture absorbent cartridge 200 are moved downward and coupled to the upper case 300. For coupling, the porous moisture absorbent cartridge 200 is moved downward by the user and the lower moisture absorbent 212 is inserted into the insertion groove S3, and the upper moisture absorbent 214 is inserted into the insertion space S2 and the insertion groove ( S3), when the porous moisture absorbent cartridge 200 compresses the seating portion 360 downward, the stepped portion of the bottom of the base 216a reaches the stepped portion 316 and the upper protrusion 318 engages. The elastic support portion is compressed until it is inserted into the groove 216e, so that the lower moisture absorber 212 of the porous moisture absorber 210 and the heater portion 382 come into close contact. In addition, when the user rotates the porous moisture absorbent cartridge 200 and the upper protrusion 318 rotates within the coupling groove 216e and is positioned on the upper side of the locking portion 216f, even if there is no compression by the user, the upper protrusion 318 Although the protrusion 318 attempts to move upward due to the tension of the elastic support, the upper protrusion 318 is prevented from being separated from the coupling groove 216e by the locking portion 216f, thereby forming a porous moisture absorbent cartridge 200 and the upper protrusion 318. The upper case 300 is firmly coupled. The coupling groove 216e and the locking portion 216f are the first coupling structure of the base 216b, and the upper protrusion 318 is the second coupling structure mounted on the inner surface of the outer case 310, and the first and second coupling structures are The porous moisture absorbent cartridge 200 and the upper case 300 are coupled by coupling between the two coupling structures, and the compressed state of the elastic portion 340 is maintained by this coupling.

Additionally, when coupled, the bottom surface of the lower extension portion 216d of the cartridge cover 216 contacts the upper surface of the extension portion 370, thereby compressing the seating portion 360 downward.

When the upper protrusion 318 is inserted and coupled to the coupling groove 265e, the non-vertical through hole 344 of the elastic portion 340 is compressed, and the height of the elastic portion 340 at this time is (D2). The height (D2) is smaller than the height (D1) of the elastic portion 340 before compression of the non-vertical through hole 344. As the elastic portion 340 is compressed, the seating portion 360 also moves downward, but due to the tensile force of the elastic portion 340 and the downward movement of the porous moisture absorbent cartridge 200, the lower moisture absorbent 212 The bottom surface and the upper surface of the heater unit 382 come into close contact with each other, and the contact force and contact area increase. Due to this increase in contact force and increase in contact area, heat energy can be transferred or spread even if the heater element is not fixedly mounted directly on the bottom surface of the porous moisture absorber cartridge 200.

In the combined state of FIG. 2(b), the vertical through holes 322a, 342a, and 362a in the elastic support portion communicate with each other to form a first vertical airflow conduit. The first vertical airflow pipe is connected to the inflow airflow pipe 420. The atomization area is adjacent to or included in the first horizontal airflow pipe, the first horizontal airflow pipe is in communication with the first vertical airflow pipe, and the first horizontal airflow pipe extends with the airflow groove 312 through the airflow through hole 368. It communicates with the second vertical airflow conduit formed between the outer surfaces of the portion 216d. The second vertical airflow pipe communicates with the second horizontal airflow pipe formed between the airflow groove 216b and the lower side of the base cover 110. The second horizontal airflow pipe communicates with the vertical through holes 122 and 112 of the upper cover unit 100.

The aerosol generating process of the aerosol generating device 1 is explained. When the control device applies power to the heater unit 382 through the electrical connection lines 384a and 384b, the heater unit 382 generates heat energy and transfers or diffuses it to the lower moisture absorber 212. The bottom surface of the lower moisture absorber 212 is atomized by thermal energy to generate aerosol. When the user inhales through the mouth piece 120, the airflow flowing in through the inflow airflow pipe 420 in communication with the external space is a first vertical airflow including vertical through holes 322a, 342a, and 362a. It enters the first horizontal airflow pipe through the pipe. An aerosol is generated at the upper side of the first horizontal airflow pipe, and the generated aerosol moves along the first horizontal airflow pipe along with the airflow, proceeds to the second vertical airflow pipe through the airflow penetration hole 368, and flows through the second vertical airflow pipe. It is discharged to the outside through the airflow groove 216b and the vertical through holes 122 and 112 communicating through the second horizontal airflow pipe communicating with the airflow pipe, and is inhaled by the user. In this embodiment, vertical through holes 122 and 112 may be referred to as discharge conduits.

As explained above, it is not limited to the specific preferred embodiments described above, and various modifications can be made by anyone skilled in the art without departing from the gist of the claims. Of course, such changes are within the scope of the claims.
