Referring to fig. 1, a schematic structure of an electronic cigarette 100 according to an embodiment of the application is shown.

As shown in fig. 1, the electronic cigarette 100 of the present application includes a tobacco rod 10 and a cartridge 20, wherein the tobacco rod 10 includes a second housing 11, the cartridge 20 includes a first housing 211, and an oil storage bin 22 is accommodated in the first housing 211, and an aerosol matrix is stored in the oil storage bin 22. The second housing 11 has a first opening 111 through which the cartridge 20 may extend partially into the first housing 211.

The electronic cigarette 100 of the application further comprises an air path 30, the air path 30 is communicated with two opposite sides of the electronic cigarette 100, a user inhales from one side of the electronic cigarette 100, so that an air pressure difference is formed on two opposite sides of the electronic cigarette 100, external air enters from the other side of the electronic cigarette 100 and enters a user mouth after being mixed with aerosol released by an atomized aerosol matrix in the electronic cigarette 100, and the suction function of the electronic cigarette 100 is realized. The gas path 30 includes an inlet gas channel 31, an outlet gas channel 32, and an atomizing chamber 33.

Second housing 11 first housing 211 when the cartridge 20 and the stem 10 of the first housing 211 of the second housing 11 are assembled together, the cartridge 20 partially extends into the interior cavity 11a of the first housing 211, and the first housing 211 of the second housing 11 cooperates to form the atomization chamber 33. Wherein the air inlet channel 31 is located in the first housing 211, and the air outlet channel 32 is located in the second housing 11. The air inlet channel 31 is communicated between the air inlet 1121 and the atomizing chamber 33, and the air outlet channel 32 is communicated between the air outlet 2121 and the atomizing chamber 33.

It will be appreciated that when a user draws the electronic cigarette 100 of the present application through the air outlet 2121 of the cartridge 20, external air enters the air inlet channel 31 via the air inlet port 1121 of the stem 10 and enters the atomizing chamber 33 along the air inlet channel 31. The aerosol matrix stored in the first housing 211 flows toward the heating element 13 of the tobacco rod 10, and absorbs heat generated by the heating element 13 to be atomized into aerosol. The aerosol may mix with the external air and enter the user's mouth along the air outlet channel 32 from the air outlet 2121 as the user draws, thereby implementing the pumping function of the electronic cigarette 100 of the present application.

Referring to fig. 2, a schematic diagram of a tobacco rod 10 according to an embodiment of the present application is shown, referring to fig. 3, a schematic diagram of another structure of a tobacco rod 10 according to an embodiment of the present application is shown, and referring to fig. 4, a schematic diagram of an exploded view of a tobacco rod 10 according to an embodiment of the present application is shown. And with reference to fig. 1. Here, for convenience of description, the arrangement direction of the cartridge 20 and the tobacco rod 10 in fig. 1 is set to a first direction 001, and the second direction 002 and the third direction 003 perpendicular to each other are perpendicular to the first direction 001.

As shown in fig. 1-4, the tobacco rod 10 of the present application further includes a diffuser 12 and a heater 13. Wherein, the diffusion member 12 and the heating member 13 are both accommodated in the second housing 11. The diffuser 12 may be made of a porous material. When the cartridge 20 and the stem 10 are assembled together, aerosol matrix within the cartridge 20 will enter the second housing 11 from the first opening 111 and flow onto the diffuser 12. The aerosol matrix flowing onto the diffuser 12 is absorbed by the diffuser 12 and diffuses in all directions to various locations of the diffuser 12.

The heating element 13 is also accommodated in the second housing 11, and the heating element 13 is annular. In the first direction 001, the heating element 13 is fixed to the surface of the diffusing element 12 remote from the opening 111. As shown in fig. 1 to 4, the annular heating member 13 is such that the heating member 13 is fitted to the surface of the diffusion member 12 adjacent to the side wall 12a of the diffusion member 12.

It will be appreciated that when the heating element 13 releases heat outwardly, the temperature of the region of the diffuser element 12 corresponding to the surface against which the heating element 13 is in contact will be relatively high, thereby enabling the aerosol matrix absorbed by the diffuser element 12 adjacent to the side wall 12a to be atomized more rapidly to form an aerosol and released outwardly from the side wall 12 a.

The tobacco rod 10 of the present application further includes a push rod 14, wherein one end of the push rod 14 is fixed to the diffusion member 12, and the other end extends out of the second housing 11 through the opening 111. When the second housing 11 and the first housing 211 are connected, as shown in fig. 1, the push rod 14 extends into the cartridge 20 to release the aerosol matrix within the cartridge 20 and enable the aerosol matrix to flow onto the diffusion member 12 and be absorbed by the diffusion member 12.

The diffuser 12 is made of an insulating and thermally conductive material. The heat released from the heating member 13 to the diffusion member 12 can be diffused through the diffusion member 12. As shown in fig. 1-4, the cross-sectional area of the heating element 13 is smaller than the cross-sectional area of the diffusion element 12 due to the aerosol substrate being in contact with the surface of the diffusion element 12. It will be appreciated that the diffuser 12 increases the heating area of the aerosol substrate by the inventive stem 10, so that the aerosol substrate flowing to the surface of the diffuser 12 can absorb more heat, thereby improving the atomization efficiency of the aerosol substrate by the inventive stem 10.

In the prior art, only a heating element is usually arranged in the electronic cigarette for heating the aerosol matrix. But is limited by the cross-sectional area of the heating element itself, as the aerosol matrix flows towards the heating element, only aerosol matrix in contact with or in close proximity to the heating element is able to atomize into aerosol under the influence of the heat of the heating element. Thereby influencing the atomization efficiency of the electronic cigarette on the aerosol matrix.

Therefore, the heating element 13 is arranged on the diffusion element 12, so that the heat released by the heating element 13 can be absorbed and diffused by the diffusion element 12, and then the aerosol substrate on the diffusion element 12 is heated. To enhance the absorption rate of the aerosol matrix to the heat of the heating member 13, thereby enhancing the atomization efficiency of the aerosol matrix by the cigarette rod 10 of the present application.

In one embodiment, the heating element 13 is annular and the difference in radius between the outer and inner rings of the annular heating element 13 is between 0.8mm and 1.5 mm. It will be appreciated that when this range is less than 0.8mm, the range of heat release from the heating element 13 to the diffusion element 12 is reduced, and when heat is transferred into the diffusion element 12, heat is also transferred to other areas not covered by the heating element 13, resulting in a relatively low temperature of the side wall 12a, thereby affecting the atomization effect.

When the range is greater than 1.5mm, the radius of the inner ring is reduced, thereby reducing the amount of aerosol substrate absorbed by the diffuser 12 and reducing the gap between the heater 13 and the push rod 14. There is an upper limit on the amount of aerosol substrate absorbed based on the diffuser 12. It will be appreciated that when aerosol matrix is collected in the gap between the smaller heating element 13 and the push rod 14, the aerosol matrix may cause the heating element 13 to be in communication with the push rod 14, possibly affecting the use of the heating element 13.

That is, the difference in radius between the outer ring and the inner ring of the annular heating element 13 is in the range of 0.8mm to 1.5mm, and the effect of heating the side wall 12a due to the excessively small heating area can be prevented from being affected while the heating function of the heating element 13 is ensured, thereby affecting the atomization effect of the tobacco rod 10 of the present application.

As shown in fig. 1, the aerosol substrate released from the side wall 12a of the diffuser 12 can be mixed with the air entering from the air inlet channel 31 in the atomizing chamber 33, and the mixed gas is formed to be released into the air outlet channel 32.

Specifically, when outside air enters the atomizing chamber 33, the air is transported toward the side wall 12a of the diffuser 12 in the second direction 002 and the third direction 003. Based on air being flowed with the suction of the user, while aerosol is released outwards in a certain temperature environment. It will be appreciated that the air flow rate in the nebulizing chamber 33 is higher than the aerosol release flow rate, so that the air will push the aerosol to mix with the air when flowing to the side wall 12a, thereby improving the mixing quality of the aerosol and the air and improving the user's taste.

Thus, the tobacco rod 10 of the present application heats the aerosol matrix absorbed by the diffuser 12 by providing the annular heating element 13 at one side of the diffuser 12, thereby improving the atomization efficiency of the aerosol matrix absorbed by the diffuser 12 near the sidewall 12a, so that the aerosol formed by atomization can be released from the sidewall 12a of the diffuser 12. Since the outside air flows onto the side wall 12a by the air pressure difference. It will be appreciated that the aerosol released from the side wall 12a will be in direct contact with the incoming air and will mix, thereby enhancing the quality of the aerosol and air mixing of the tobacco rod 10 of the present application and enhancing the user experience.

In one embodiment, as shown in fig. 1-4, a gap is left between the side wall 12a of the diffuser 12 and the inner wall 11b of the second housing 11. When the cartridge 20 and the stem 10 are assembled as a unit, as shown in fig. 1, external air can flow from the atomizing chamber 33 through the gap into the reservoir 22 on the other side of the diffuser 12, thereby balancing the air pressure on opposite sides of the diffuser 12 and ensuring that the aerosol substrate flows from the reservoir 22 toward the diffuser 12.

In one embodiment, the diffuser 12 is provided with a first ventilation slot 121, wherein the first ventilation slot 121 extends through the diffuser 12 along the first direction 001 to form a void. The first ventilation slots 121 allow outside air to communicate with opposite sides of the diffuser 12 and do not allow the aerosol substrate to leak outwardly through the first ventilation slots 121. It will be appreciated that the provision of the first ventilation slots 121 also enables air on opposite sides of the diffuser 12 to be conducted while avoiding leakage of aerosol substrate, thereby enabling air pressure on opposite sides of the diffuser 12 to be relatively balanced and ensuring flow smoothness of the aerosol substrate.

It is understood that in the present embodiment, the first ventilation groove 121 is provided on the sidewall 12a of the diffuser 12 to form a gap. In other embodiments, the first ventilation slots 121 may be disposed elsewhere in the diffuser 12 to form voids, which are not particularly limited in the present application.

In one embodiment, the heating element 13 is a resistive layer.

In one embodiment, as shown in fig. 1-4, the tobacco rod 10 of the present application further includes a battery 15, where the battery 15 is accommodated in the second housing 11 and is located at a side of the heating element 13 facing away from the opening 111. As shown in fig. 3, the battery 15 is electrically connected to the heating element 13. It will be appreciated that the battery 15 provides electrical energy to the heating element 13 to enable the heating element 13 to generate heat, thereby ensuring the aerosol-generating function of the stem 10 of the present application.

In one embodiment, in the first direction 001, the heating element 13 is fixed to the surface of the diffusing element 12 near the opening 111, and the pushing rod 14 passes through the heating element 13 with a gap between the heating elements 13. It will be appreciated that aerosol matrix flowing from the opening 111 may flow from the gap between the heating element 13 and the push rod 14 to the diffuser 12 and be absorbed by the diffuser 12. The heat generated by the heating member 13 can also directly heat the aerosol substrate that is not absorbed by the diffusion member 12 to atomize the aerosol substrate into an aerosol.

That is, the heating member 13 and the pushing rod 14 are disposed at the same side of the diffusion member 12, so that the aerosol substrate flowing in from the opening 111 can be directly heated and atomized to form aerosol while the atomization effect of the heating member 13 on the aerosol substrate absorbed by the diffusion member 12 is ensured, thereby improving the atomization efficiency of the aerosol substrate by the tobacco rod 10 of the present application.

Specifically, referring to fig. 5, a schematic cross-sectional structure of a tobacco rod 10 according to an embodiment of the present application is shown, and referring to fig. 6, a schematic partial structure of a tobacco rod 10 according to an embodiment of the present application is shown.

As shown in fig. 5 and 6, the tobacco rod 10 of the present application further includes two transmission members 16, the two transmission members 16 are spaced apart from each other, one end of each of the two transmission members 16 is electrically connected to the battery 15, and the other end of each of the two transmission members is electrically connected to the heating member 13 through the diffusion member 12. It will be appreciated that the current of the battery 15 can be transferred to the heating element 13 via the diffusion element 12, so that the heating element 13 can release heat outwards, thus achieving the atomizing function of the stem 10 of the present application.

Wherein, as shown in fig. 5 and 6, the diffuser 12 comprises two mutually spaced through holes 122 along the second direction 002. Each transmission member 16 includes a conductive segment 161 and a holding segment 162. The conductive sections 161 of each transmission member 16 are respectively filled in one through hole 122 to ensure the electrical connection between the transmission member 16 and the heating member 13. The supporting section 162 is attached to the surface of the diffusion member 12 near the battery 15 and covers the corresponding through hole 122, and the supporting section 162 is further electrically connected to the conductive section 161.

The tobacco rod 10 according to the present application has a relatively small size in the second direction 002, and correspondingly, the diameter of the through hole 122 provided in the diffuser 12 is also relatively small. It can be appreciated that the arrangement of the abutting section 162 increases the contact area between the battery 15 and the transmission member 16, and avoids the influence on the electrical connection between the transmission member 16 and the battery 15 due to the small through hole 122, thereby reducing the difficulty of the electrical connection between the battery 15 and the transmission member 16.

Referring to fig. 7, a schematic diagram of another cross-sectional structure of a tobacco rod 10 according to an embodiment of the present application is shown, and referring to fig. 8, a schematic diagram of another partial structure of a tobacco rod 10 according to an embodiment of the present application is shown.

As shown in fig. 7 and 8, along the second direction 002, two grooves 123 spaced apart from each other are provided on the side wall 12a of the diffusion member 12, one end of each transmission member 16 is electrically connected to the heating member 13 through one groove 123, and the other end of each transmission member 16 is electrically connected to the battery 15.

It will be appreciated that providing the recess 123 in the side wall 12a reduces the difficulty of machining the diffuser 12 while allowing the transfer member 16 to pass through the diffuser 12 to electrically connect the battery 15 and the heater 13 on opposite sides of the diffuser 12. Meanwhile, the transmission piece 16 can extend along the second direction 002 towards the direction away from the diffusion piece 12, so that the contact area of the electric connection between the battery 15 and the transmission piece 16 is increased, and the difficulty of the electric connection between the battery 15 and the transmission piece 16 is reduced.

In one embodiment, as shown in fig. 1-8, the second housing 11 further includes a bottom cover 112, and the bottom cover 112 is fixed to an end of the second housing 11 away from the opening 111 to form an inner cavity 11a in cooperation with the second housing 11. The battery 15 is fixed to an end of the bottom cover 112 facing the opening 111 and spaced apart from the bottom cover 112 in the first direction 001. In the third direction 003, the battery 15 is also spaced from the second housing 11.

The bottom cover 112 is provided with an air inlet 1121. It is understood that the external air may be sequentially transferred to the opening 111 through the gap between the battery 15 and the bottom cover 112 and the gap between the battery 15 and the second housing 11 via the air intake hole 1121, thereby forming the air intake passage 31.

In one embodiment, as shown in fig. 1-8, the tobacco rod 10 further includes a fixing plate 113, the fixing plate 113 being located between the battery 15 and the diffusion member 12 and being fixed with the second housing 11. The push rod 14 also passes through the diffuser 12 in a first direction 001 and extends away from the diffuser 12. Wherein, the side of the push rod 14 away from the opening 111 is detachably connected with the fixed plate 113.

Based on the push rod 14 and the diffusion member 12, and the heating member 13 and the diffusion member 12 are fixedly connected. It will be appreciated that the push rod 14 is detachably connected to the fixing plate 113, so that the diffusion member 12 and the heating member 13 can be fixed to the tobacco rod 10 while the position of the push rod 14 is defined, thereby achieving the position fixation of the diffusion member 12 and the heating member 13.

Meanwhile, the push rod 14 detachably connected with the fixed plate 113 is arranged, and when the push rod 14, the heating piece 13 or the diffusion piece 12 is damaged, the push rod 14 is convenient to directly detach, so that the push rod 14, the heating piece 13 or the diffusion piece 12 can be replaced. Thereby improving the user experience of the electronic cigarette 100 of the present application.

In one embodiment, the fixed plate 113 is provided with a communication hole 1131 such that air taken in from the intake hole 1121 can be output from the communication hole 1131 via the intake passage 31.

In one embodiment, as shown in fig. 1-8, the tobacco rod 10 further includes a conductive post 171 and a connecting wire 172, one end of the conductive post 171 is electrically connected to the heating element 13, and the other end of the conductive post 171 is fixed and penetrates through the fixing plate 113 and is electrically connected to two poles of the battery 15 through one connecting wire 172.

As shown in fig. 3, the conductive post 171 is in contact with the heating element 13. It can be understood that the electric energy in the battery 15 is respectively transmitted to the corresponding connecting wires 172 via the two poles, and then sequentially transmitted to the heating element 13 via the connecting wires 172 and the conductive poles 171, so as to realize the atomizing function of the cigarette rod 10 of the present application.

As shown in fig. 5, the conductive post 171 is in abutting conduction with the abutting section 162. It can be understood that the electric energy in the battery 15 is respectively transmitted to the corresponding connecting wires 172 via the two poles, and then sequentially transmitted to the heating element 13 via the connecting wires 172, the conductive poles 171, the supporting section 162 and the conductive section 161, so as to realize the atomizing function of the cigarette rod 10.

As shown in fig. 7, the conductive post 171 is in abutting communication with the transmission member 16. It can be understood that the electric energy in the battery 15 is respectively transmitted to the corresponding connecting wires 172 via the two poles, and then is sequentially transmitted to the heating element 13 via the connecting wires 172, the conductive poles 171 and the transmitting element 16, so as to realize the atomizing function of the cigarette rod 10.

In one embodiment, as shown in fig. 1-8, the tobacco rod 10 further includes a sensor 181, and the bottom cover 112 is further provided with an induction air hole 1122. The induction air holes 1122 communicate between the outside air and the air intake passage 31. The sensor 181 is fixedly connected to the bottom cover 112 and covers the sensing air holes 1122. One end of the sensor 181 is electrically connected to one of the poles of the battery 15, and the other end is electrically connected to one of the connecting wires 172.

And the sensor 181 can be triggered to conduct the battery 15, the pole and the connecting wire 172, so that the current transmission between the battery 15 and the heating element 13 is realized, and the atomization function of the cigarette rod 10 is realized.

When outside air does not enter the air intake passage 31 through the sensing air hole 1122, the sensor 181 breaks the electrical connection between the battery 15 and the connection wire 172.

The aerosol matrix flows out of the outlet opening 222, flows into the second connecting opening 233 via the first connecting opening 232, and contacts the diffuser 12.

Since the dispersing member 12 is required to absorb and guide the aerosol matrix toward the heating member 13 to be atomized into aerosol, the aerosol matrix discharged from the liquid outlet holes 222 is not stopped from being discharged because the aerosol matrix is not atomized. It will be appreciated that a portion of the aerosol matrix is stored between the diffuser 12 and the spacer 221, and the portion of the aerosol matrix diffuses around based on the relatively larger aperture of the second connection holes 233 compared to the first connection holes 232, so that the contact area between the aerosol matrix and the diffuser 12 is increased, and the absorption efficiency of the diffuser 12 to the aerosol matrix is increased.

The seal 23 is exposed based on the presence of a partial region of the diffuser 12, and the diffuser 12 is made of a porous material. It will be appreciated that external air may also enter the second connection hole 233 via the aperture in the diffuser 12, and cooperate with the second ventilation groove 231 to achieve air pressure balance between the oil reservoir 22 and the external environment, thereby ensuring the smoothness of the release of the aerosol matrix in the oil reservoir 22.

Thereby realizing the pumping function of the user to the electronic cigarette 100 of the present application.

Please refer to fig. 11 for a schematic view of a partial structure of a cartridge 20 according to an embodiment of the present application, and fig. 12 for a schematic view of a partial cross-section of a cartridge 20 according to an embodiment of the present application.

When the cartridge 20 and the stem 10 are assembled as a unit, the push rod 14 pushes the sealing plug 241 to move in a direction away from the partition 221. The force of the push rod 14 pushing the movement of the sealing plug 241 is transmitted to the sealing plate 243 via the connecting piece 242 and presses the sealing plate 243 so that the sealing plate 243 is deformed.

Meanwhile, when the cartridge 20 and the stem 10 are disconnected, the push rod 14 exits the liquid outlet hole 222, the elastic force stored in the sealing plate 243 acts on the connecting piece 242, and the connecting piece 242 pushes the sealing plug 241 to move towards the partition 221 and prop against and shield the liquid outlet hole 222, so as to realize the sealing of the cartridge 20 to the aerosol matrix.

In one embodiment, as shown in fig. 9 and 10, the partition 221 is provided with a guide structure 221a, and the guide structure 221a is connected to an end of the liquid outlet 222 facing the inside of the oil reservoir 22. The guide structure 221a is tapered and includes a first guide port 2211 and a second guide port 2212 disposed opposite to each other. Wherein, the first guiding port 2211 is communicated with the liquid outlet hole 222, and the aperture of the first guiding port 2211 is smaller than that of the second guiding port 2212. That is, the end of the guide structure 221a with the larger cross section is far away from the liquid outlet hole 222, and the end with the smaller cross section is close to the liquid outlet hole 222.

It will be appreciated that the sealing plug 241 of the switch assembly 24 can extend into the second guide port 2212 and abut against the inner wall of the guide structure 221a to seal the first guide port 2211 and thereby the liquid outlet hole 222. Thereby ensuring the sealing effect of the cartridge 20 against the aerosol matrix.

In one embodiment, as shown in fig. 9 and 10, the sealing plug 241 of the switch assembly includes a holding portion 2411, and the holding portion 2411 is located at an end of the sealing plug 241 near the liquid outlet hole 222. The abutting portion 2411 is tapered. One end of the abutting portion 2411 with a smaller cross section is close to the liquid outlet 222 and at least partially attached to the guiding structure 221 a.

It can be appreciated that the abutting portion 2411 extends into the second guiding hole 2212 and abuts against the inner wall of the guiding structure 221a to seal the first guiding hole 2211, thereby sealing the liquid outlet hole 222. Further improving the sealing effect of the sealing plug 241 on the liquid outlet 222. Further ensuring the sealing effect of the electronic cigarette 100 of the application on the aerosol substrate.

Referring to fig. 13, another schematic structure of an electronic cigarette 100 according to an embodiment of the application is shown.

As shown in fig. 13, the electronic cigarette 100 further includes a liquid guiding member 40, the liquid guiding member 40 is fixed on the outer surface of the partition 221 near the oil storage bin 22, and a through guide hole 41 is provided in the liquid guiding member 40, so that the push rod 14 can enter the liquid outlet hole 222 through the guide hole 41.

As shown in fig. 13, the liquid guide 40 is made of a porous material. When the cartridge 20 and the stem 10 are assembled together, the push rod 14 releases the aerosol matrix within the reservoir 22, which can flow from the outlet aperture 222 onto the liquid guide 40 and be absorbed by the liquid guide 40. The liquid guide 40 is capable of guiding the aerosol substrate toward the heating member 13 and the dispersing member 12, and atomizing the aerosol substrate to form an aerosol in cooperation with heat released from the heating member 13 and the dispersing member 12. Thereby realizing the atomizing function of the electronic cigarette 100 of the application on aerosol matrixes.

In one embodiment, both the liquid guide 40 and the diffusion member 12 are made of porous materials, and the porosity of the liquid guide 40 is greater than the porosity of the diffusion member 12. Since the size of the porosity is related to the liquid absorbing capacity and the penetrating capacity of the material, the larger the porosity of the material, the larger the corresponding number of closed pores, the smaller the diameter of the pores, the stronger the liquid absorbing capacity and the penetrating capacity of the material.

Based on more aerosol matrix entering the liquid guide 40 than into the diffuser 12. It will be appreciated that the provision of the liquid guide 40 having a relatively high porosity enables the aerosol matrix released from the liquid outlet aperture 222 to be absorbed relatively quickly, avoiding accumulation of aerosol matrix between the liquid outlet aperture 222 and the liquid guide 40, thereby causing the aerosol matrix to exude through between the liquid guide 40 and the first housing 211.

Meanwhile, the aerosol matrix absorbed by the liquid guide member 40 can be rapidly diffused into the whole liquid guide member 40 based on the higher porosity corresponding to the stronger permeability of the material, so that the matching of the heat released by the heating member 13 and the diffusion member 12 and the capacity of the aerosol matrix guided towards the heating member 13 is realized, and the quantity of the aerosol released by the electronic cigarette 100 is ensured.

When there is a portion of the aerosol matrix that overflows to the surface of the diffuser 12, the porosity based diffuser 12 is smaller compared to the porosity of the liquid guide 40. The aerosol matrix that overflows to the surface of the diffuser 12 is relatively slow to penetrate while being absorbed by the absorbing diffuser. Because the temperature decreases with increasing distance from the heating element 13, the amount of heat absorbed by the aerosol matrix correspondingly decreases. It will be appreciated that the provision of a less porous diffuser 12 reduces the rate of penetration of the aerosol matrix and thus extends the penetration time of the aerosol matrix so that the aerosol matrix can absorb more heat to atomize to form an aerosol.

That is, the matching arrangement of the porosities of the diffusion member 12 and the liquid guiding member 40 increases the amount of heat generated by the heating member 13 absorbed by the aerosol base material, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and enhancing the experience of the user using the electronic cigarette 100 of the present application.
