Technical Field

[0002] The present application relates to the field of electronic cigarettes, and in particular to an electronic cigarette cartridge, an electronic cigarette rod assembly, and an electronic cigarette. Background Art

[0003] In the prior art, an e-cigarette typically consists of a cartridge and a stem. The cartridge houses an atomizer assembly, while the stem houses a battery that is electrically connected to the atomizer assembly's heater. The cartridge also stores an aerosol matrix, which is absorbed by the atomizer assembly and released as aerosol under the action of the heater. The released aerosol mixes with air and is then discharged from the cartridge's mouthpiece.

[0004] To extend the lifespan of e-cigarettes, a single cigarette holder is typically paired with multiple cartridges. When the aerosol matrix in a single cartridge is depleted, a new cartridge can be replaced for continued use. However, in existing technologies, the atomizer assembly within the cartridge is also wasted when the cartridge is discarded, increasing the cost of using the e-cigarette for users.

[0005] Summary of the Invention

[0139] In a first aspect, embodiments of the present application provide an electronic cigarette cartridge, comprising a first housing and an oil storage tank housed within the first housing, the oil storage tank being used to store an aerosol matrix. The cartridge further comprises a liquid guide member, the liquid guide member comprising a first end and a second end opposite to each other, the first end being closer to the oil storage tank than the second end, and the second end being located outside the first housing.

[0140] The liquid guiding member has a porous structure, and the liquid guiding member absorbs the aerosol matrix released from the oil storage tank through the first end.

[0141] The cigarette cartridge of the present application is provided with an oil storage tank housed in the first shell, and a liquid guide member with a porous structure, so that the aerosol matrix in the oil storage tank can flow outward through the liquid guide member, thereby realizing the release function of the cigarette cartridge of the present application on the aerosol matrix.

[0142] The cigarette cartridge of the present application also arranges the first end of the liquid-guiding component between the oil storage tank and the second end, and arranges the second end outside the first shell, and cooperates with the porous structure inside the liquid-guiding component to enable the aerosol matrix to infiltrate from the first end to the side wall of the second end, and after absorbing external heat at the second end, it is atomized to form an aerosol and released outward from the side wall to facilitate mixing with the external air, thereby improving the mixing quality of air and aerosol and enhancing the user experience.

[0143] In one embodiment, the distance between the second end and the first housing is between 0.5 mm and 2 mm.

[0144] In one embodiment, the cigarette cartridge further includes a partition, which is fixed to the first shell and encloses the first shell to form an oil storage tank. A liquid outlet is provided on the partition, and the first end of the liquid guide absorbs the aerosol matrix in the oil storage tank through the liquid outlet.

[0145] In one embodiment, the first end of the liquid guide is fixed to the partition and at least partially covers the liquid outlet. The aerosol matrix precipitates out of the oil storage tank through the first end and infiltrates the side wall of the liquid guide.

[0146] In one embodiment, the first end of the liquid guiding member is spaced apart from the partition, and along the length direction of the liquid guiding member, the projection of the first end on the partition accommodates the liquid outlet.

[0147] In one embodiment, the cigarette cartridge includes a third shell, which accommodates the first shell and is spaced apart from the first shell. The third shell is provided with an air outlet, which is connected to the gap between the first shell and the third shell.

[0148] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge, the cigarette rod comprising an atomizer assembly and a second shell having a first opening, the cigarette cartridge at least partially extending into the second shell through the first opening; the atomizer assembly is disposed in the second shell, the second end of the liquid guide member in the cigarette cartridge extending into the second shell through the first opening, and the atomizer assembly is close to or attached to the second end to atomize the aerosol matrix.

[0149] In one embodiment, the atomization assembly includes a diffuser and a heater. The diffuser is made of an insulating heat-conductive material. The heater is fixed to the diffuser to heat the diffuser.

[0150] In one embodiment, the atomization assembly includes a heating element, and the material of the heating element is metal; and / or the heating element is a resistance layer.

[0151] In one embodiment, the second shell further includes an air inlet hole, the cigarette cartridge and the cigarette rod enclose an atomization chamber, the air inlet hole is connected to the atomization chamber, and the second end of the liquid guide member is located in the atomization chamber.

[0152] It can be understood that since the electronic cigarette provided in the second aspect of this application adopts the cigarette cartridge provided in the first aspect of this application, it also has the beneficial effects of improving mixing quality and enhancing user experience.

[0153] Please refer to FIG1 , which is a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0154] As shown in FIG1 , the electronic cigarette 100 of the present application includes a cartridge 10 and a cigarette rod 20, wherein the cartridge 10 includes a first shell 111, and the cigarette rod 20 includes a second shell 21. The first shell 111 houses an oil storage tank 12, which stores an aerosol matrix, and the second shell 21 is provided with an atomizer assembly 22. It should be understood that "the first shell 111 houses the oil storage tank 12" means that the oil storage tank 12 is a space enclosed by the first shell 111.

[0155] The second housing 21 has a first opening 211 through which the cartridge 10 can partially extend into the second housing 21. At the same time, part of the liquid guide 13 in the cartridge 10 can extend into the second housing 21 through the first opening 211 and approach the atomizer assembly 22.

[0156] When the aerosol matrix in the first shell 111 flows toward the atomizer assembly 22, the aerosol matrix can enter the second shell 21 through the liquid guide 13 and absorb the heat released by the atomizer assembly 22 to heat the aerosol matrix to form an aerosol. The electronic cigarette 100 of the present application also includes an air circuit 30, which is connected to the opposite sides of the electronic cigarette 100. The user inhales from one side of the electronic cigarette 100 to form an air pressure difference on the opposite sides of the electronic cigarette 100, so that the outside air enters from the other side of the electronic cigarette 100 and mixes with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and enters the user's mouth, thereby realizing the suction function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air outlet channel 31, an air inlet channel 32 and an atomizer chamber 33.

[0157] When the cigarette cartridge 10 and cigarette rod 20 are assembled, the second housing 21 partially extends into the inner cavity 11a of the first housing 111, forming an atomization chamber 33. The air inlet channel 32 is located within the second housing 21, and the air outlet channel 31 is located within the first housing 111. The air inlet channel 32 communicates between the air inlet hole 2121 and the atomization chamber 33, while the air outlet channel 31 communicates between the air outlet hole 1121 and the atomization chamber 33.

[0158] It is understood that when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 32 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 32. The aerosol matrix stored in the first shell 111 flows toward the atomization assembly 22 of the cigarette rod 20 and absorbs the heat generated by the atomization assembly 22 to be atomized into aerosol. The aerosol mixes with the external air and, as the user inhales, enters the user's mouth through the air outlet 1121 along the air outlet channel 31, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0159] Specifically, please refer to FIG2 , a schematic diagram of the structure of the cigarette cartridge 10 provided in one embodiment of the present application, and FIG3 , an exploded schematic diagram of the cigarette cartridge 10 provided in one embodiment of the present application. In conjunction with FIG1 , for ease of description, the assembly direction of the cigarette cartridge 10 and cigarette rod 20 in FIG1 is set as a first direction 001 , with a second direction 002 perpendicular to the first direction 001 .

[0160] As shown in Figures 1, 2, and 3, the cigarette cartridge 10 of the present application further includes an oil storage tank 12, which is housed within the first housing 111 and is used to store the aerosol matrix. The cigarette cartridge 10 further includes a liquid guide 13, which includes a first end 13a and a second end 13b that are opposite to each other. The first end 13a is located closer to the inside of the first housing 111, while the second end 13b is located outside the first housing 111.

[0161] As shown in Figure 1 , when the cigarette cartridge 10 and cigarette rod 20 are assembled, the second end 13b can extend into the second housing 21 through the first opening 211 and engage with the atomizer assembly 22. This allows the atomizer assembly 22 to heat the liquid-guiding member 13. It is understood that in another embodiment, the atomizer assembly 22 can also be spaced apart from the second end 13b of the liquid-guiding member 13.

[0162] As shown in Figures 2 and 3, the liquid guiding member 13 has a porous structure, and the porous structure inside the first end 13a of the liquid guiding member 13 can absorb the aerosol matrix in the oil storage tank 12. This part of the aerosol matrix can infiltrate into the side wall 131 of the liquid guiding member 13 through the porous structure. The second end 13b of the liquid guiding member 13 can absorb the heat released by the atomization component 22 in the cigarette rod 20 and atomize the aerosol matrix to form an aerosol.

[0163] Because the liquid-guiding member 13 and the atomizing assembly 22 are in close contact with each other, and the sidewall 131 of the liquid-guiding member 13 extends beyond the first housing 111, it is understood that the aerosol formed is primarily released from the sidewall 131 of the liquid-guiding member 13. As shown in FIG1 , the aerosol matrix released from the sidewall 131 of the liquid-guiding member 13 can mix with the air entering from the air inlet passage 32 within the atomizing chamber 33, forming a mixed gas that is released into the air outlet passage 31.

[0164] Specifically, when external air enters the atomization chamber 33, it is transported along the second direction 002 toward the sidewall 131 of the liquid guide 13. Since air flows as the user inhales, while aerosol is released outward under a certain temperature environment, it is understandable that the air flow rate within the atomization chamber 33 is higher than the aerosol release rate. As the air flows to the sidewall 131, it promotes the mixing of the aerosol and air, thereby improving the mixing quality of the aerosol and air and enhancing the user's taste.

[0165] In existing technology, the atomizer assembly is typically placed inside a cigarette cartridge. The atomizer chamber is typically the space between the atomizer assembly and the internal structure of the cigarette rod. After being heated by the atomizer assembly, the aerosol matrix in the cigarette cartridge is released from the surface of the atomizer assembly near the internal structure of the cigarette rod. When external air enters the atomizer chamber, the relatively large area of ​​the atomizer chamber results in poor mixing of the aerosol and air, thus affecting the user experience.

[0166] Therefore, the cigarette cartridge 10 of the present application arranges the second end 13b of the liquid guide 13 outside the first shell 111 so that the aerosol matrix in the liquid guide 13 can be released from the side wall 131 under the action of the atomizer assembly 22 in the cigarette rod 20. Since the fit between the liquid guide 13 and the atomizer assembly 22 reduces the space of the atomizer chamber 33, the external air will flow to the side wall 131 under the action of the air pressure difference. It can be understood that the aerosol released from the side wall 131 and the inflowing air will directly contact and mix, thereby improving the mixing quality of the aerosol and air in the cigarette cartridge 10 of the present application and enhancing the user experience.

[0167] In one embodiment, the distance between the second end 13b and the first shell 111 is between 0.5mm and 2mm. The length of the second end 13b outside the first shell 111 will affect the amount of aerosol released. It is understandable that when the distance between the second end 13b and the first shell 111 is less than 0.5mm, there may be a situation where part of the aerosol formed by atomization cannot be released from the inside of the liquid guide 13 to the outside, resulting in part of the aerosol coming into contact with the remaining aerosol matrix with a lower temperature and condensing into an aerosol matrix. This thereby reduces the amount of aerosol released by the liquid guide 13, reduces the proportion of aerosol in the gas inhaled by the user, and affects the user experience.

[0168] When the distance between the second end 13b and the first housing 111 is greater than 2 mm, some aerosol matrix may flow out of the side wall 131 before being atomized into aerosol, causing the aerosol matrix to flow into the atomization chamber 33. This may cause the substance inhaled by the user to contain part of the aerosol matrix in addition to the mixed gas of aerosol and air, affecting the user's experience.

[0169] Therefore, the cigarette cartridge 10 of the present application limits the distance between the second end 13b and the first shell 111 to between 0.5mm and 2mm, and can avoid leakage of the aerosol matrix from the side wall 131 while ensuring the amount of aerosol released from the side wall 131 of the liquid-guiding member 13, thereby ensuring the user's usage experience.

[0170] In one embodiment, as shown in Figures 2 and 3, the cigarette cartridge 10 further includes a partition 121, which is fixed within the first housing 111 and cooperates with the first housing 111 to enclose the oil storage bin 12. The partition 121 is provided with a liquid outlet 122. As can be understood, the first end 13a of the liquid guide 13 can absorb the aerosol matrix stored in the oil storage bin 12 through the liquid outlet 122.

[0171] The liquid guiding member 13 is located on one side of the partition 121 along the first direction 001 , and the first end 13 a of the liquid guiding member 13 can absorb the aerosol matrix flowing out of the liquid outlet 122 and precipitate it out of the first shell 111 .

[0172] Specifically, as shown in Figures 2 and 3, the first end 13a of the liquid guide 13 is spaced apart from the partition 121 along the first direction 001, and in the first direction 001, the projection of the first end 13a on the partition 121 accommodates the liquid outlet 122, thereby ensuring that the aerosol matrix flowing out of the liquid outlet 122 can flow to the first end 13a and be absorbed by the first end 13a.

[0173] In another embodiment, as shown in Figures 4 and 5, the first end 13a of the liquid-guiding member 13 can also be fixed to the partition 121 along the first direction 001 and completely cover the liquid outlet 122. Based on the porous structure of the liquid-guiding member 13, it is understandable that the aerosol matrix stored in the oil storage tank 12 can contact the first end 13a of the liquid-guiding member 13 through the liquid outlet 122 and precipitate out of the oil storage tank 12 under the action of the first end 13a. The aerosol matrix absorbed by the first end 13a can infiltrate the side wall 131 of the liquid-guiding member 13 under the action of the porous structure and be atomized to form an aerosol under the action of the heat absorbed by the second end 13b.

[0174] It is understandable that in other embodiments, the first end 13a of the liquid guide 13 may also be fixed to the partition 121 along the first direction 001 and partially cover the liquid outlet 122. This application does not impose any particular limitation on this.

[0175] In one embodiment, as shown in FIG. 2 and FIG. 3 , a guide hole 132 is further provided on the liquid guide member 13 , so that the push rod 231 of the cigarette rod 20 can pass through the guide hole 132 into the liquid outlet 122 and release the aerosol matrix in the oil storage tank 12 .

[0176] In one embodiment, as shown in FIG2 and FIG3 , the cigarette cartridge 10 further includes a third shell 112 , wherein the first shell 111 is received in the third shell 112 .

[0177] The third housing 112 is provided with an air outlet hole 1121 . The first housing 111 and the third housing 112 are spaced apart from each other to form an air outlet channel 31 between the first housing 111 and the third housing 112 . The air outlet channel 31 is also communicated with the air outlet hole 1121 .

[0178] It is understandable that the aerosol formed from the side wall 131 of the liquid guide 13 can flow from the atomization chamber 33 through the air outlet channel 31 to the air outlet 1121 and be output from the air outlet 1121, thereby realizing the user's inhalation function of the electronic cigarette 100 of the present application.

[0179] In one embodiment, as shown in Figures 2 and 3, the cigarette cartridge 10 further includes a switch assembly 14. The switch assembly 14 is housed in the oil storage bin 12, and along the first direction 001, one end of the switch assembly 14 is used to abut and cover the liquid outlet 122, and the other end is elastically connected to the oil storage bin 12.

[0180] It can be understood that, as shown in Figure 1, when the push rod 231 of the cigarette holder 20 extends into the liquid outlet 122, the push rod 231 can abut against the switch assembly 14 and push the switch assembly 14 to move in a direction away from the partition 121, thereby opening the liquid outlet 122 to release the aerosol matrix in the oil storage tank 12.

[0181] In one embodiment, a sealing opening 1111 is provided on a side of the first housing 111 away from the partition 121. The switch assembly 14 includes a sealing plate 143 that is fixed to and covers the sealing opening 1111. The first housing 111, the partition 121, and the sealing plate 143 together form the oil storage tank 12.

[0182] In one embodiment, as shown in Figures 2 and 3 , the switch assembly 14 further includes a sealing plug 141 and a connector 142 , wherein one end of the connector 142 is fixedly connected to the sealing plug 141 , and the other end is fixedly connected to the sealing plate 143 .

[0183] As shown in Figure 1, the sealing plate 143 is elastic. When the cigarette cartridge 10 and cigarette rod 20 are assembled, the push rod 231 of the cigarette rod 20 pushes the sealing plug 141 away from the partition 121. The force of the push rod 231 pushing the sealing plug 141 is transmitted to the sealing plate 143 via the connector 142, squeezing the sealing plate 143 and causing it to deform.

[0184] At the same time, when the cigarette cartridge 10 and the cigarette rod 20 are disconnected, the push rod 231 withdraws from the liquid outlet 122, and the elastic force stored in the sealing plate 143 acts on the connecting member 142, causing the connecting member 142 to push the sealing plug 141 toward the partition 121, and resist and cover the liquid outlet 122, so as to achieve the sealing of the aerosol matrix by the cigarette cartridge 10 of this application.

[0185] In one embodiment, as shown in Figures 2 and 3 , a guide structure 121a is provided on the partition 121. The guide structure 121a is connected to the end of the liquid outlet 122 facing the inner side of the oil storage tank 12. The guide structure 121a is conical and includes a first guide opening 1211 and a second guide opening 1212 disposed opposite each other. The first guide opening 1211 is connected to the liquid outlet 122, and the aperture of the first guide opening 1211 is smaller than that of the second guide opening 1212. In other words, the end of the guide structure 121a with a larger cross-section is farther away from the liquid outlet 122, while the end with a smaller cross-section is closer to the liquid outlet 122.

[0186] It is understandable that the sealing plug 141 of the switch assembly 14 can extend into the second guide opening 1212 and abut against the inner wall of the guide structure 121a to seal the first guide opening 1211 and thus the liquid outlet 122, thereby further ensuring the sealing effect of the cigarette cartridge 10 on the aerosol matrix.

[0187] In one embodiment, as shown in Figures 2 and 3 , the sealing plug 141 of the switch assembly includes a supporting portion 1411 located at one end of the sealing plug 141 near the liquid outlet 122. The supporting portion 1411 is tapered. The end of the supporting portion 1411 with a smaller cross-section is located near the liquid outlet 122 and at least partially engages with the guide structure 121a.

[0188] As can be understood, the abutting portion 1411 extends into the second guide opening 1212 and abuts against the inner wall of the guide structure 121a, thereby sealing the first guide opening 1211 and thus the liquid outlet 122. This further enhances the sealing effect of the sealing plug 141 on the liquid outlet 122, further ensuring the sealing effect of the cigarette cartridge 10 of the present application on the aerosol matrix.

[0189] Please refer to FIG6 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG7 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG2 .

[0190] As shown in Figures 2, 6, and 7, the cigarette cartridge 10 of the present application further includes a support member 15. The first shell 111 is cylindrical, and a plurality of support members 15 are provided. The plurality of support members 15 are spaced apart along the circumference of the first shell 111, and each support member 15 is fixed between the first shell 111 and the third shell 112.

[0191] A gap is left between each two adjacent support members 15 to form an air outlet channel 31. It can be understood that the mixed gas of aerosol and air formed by mixing from the atomization chamber 33 can be transmitted from between the two adjacent support members 15 to the air outlet 1121 and output to the outside.

[0192] In one embodiment, as shown in Figures 6 and 7, the cigarette cartridge 10 further includes a liquid wick 16, which is disposed between each two adjacent support members 15 and spaced apart from at least one support member 15 to ensure that the mixed gas of aerosol and air formed from the atomization chamber 33 can be discharged. The liquid wick 16 can be used to absorb the aerosol matrix condensed during the transmission process, preventing the aerosol matrix from entering the mouth through the outlet channel 31, thereby ensuring a good user experience.

[0193] In one embodiment, referring back to Figures 1 and 2 , the cigarette cartridge 10 further includes a sealing member 17, one end of which is fixed to the partition 121, and the other end of which extends toward the liquid guide member 13 and is fixed between the liquid guide member 13 and the first shell 111. The sealing member 17 is used to prevent the aerosol matrix from overflowing from the gap between the liquid guide member 13 and the first shell 111.

[0194] The sealing member 17 is provided with a first connecting hole 171 , a second connecting hole 172 and a third connecting hole 173 , wherein the diameter of the second connecting hole 172 is larger than that of the first connecting hole 171 and smaller than that of the third connecting hole 173 .

[0195] Along the first direction 001, the projection of the liquid outlet 122 on the sealing member 17 is received within the first connection hole 171. The first end 13a of the liquid guide member 13 extends into and is received within the third connection hole 173, while the second end 13b of the liquid guide member 13 extends out of the third connection hole 173. The aerosol matrix flows out of the liquid outlet 122, through the first connection hole 171, into the second connection hole 172, and contacts the first end 13a of the liquid guide member 13 located within the third connection hole 173.

[0196] Because the liquid guide 13 needs to absorb the aerosol matrix and guide it toward the atomizer assembly 22 before it can be atomized into an aerosol, the aerosol matrix released from the liquid outlet 122 does not stop being released due to the aerosol matrix not being atomized. It is understandable that a portion of the aerosol matrix is ​​stored in the second connection hole 172, and this portion of the aerosol matrix will diffuse outward due to the relatively larger aperture of the second connection hole 172 compared to the first connection hole 171, thereby increasing the contact area between the aerosol matrix and the liquid guide 13 and improving the liquid guide 13's efficiency in absorbing the aerosol matrix.

[0197] Because the second end 13b of the liquid-guiding member 13 is exposed from the sealing member 17 and the liquid-guiding member 13 is made of a porous material, it is understood that external air can also enter the second connecting hole 172 through the pores within the liquid-guiding member 13, and achieve pressure balance between the oil storage tank 12 and the external environment through the liquid outlet 122, ensuring smooth release of the liquid in the oil storage tank 12. This, in turn, enhances the user experience. Please refer to Figure 8 for a schematic structural diagram of a cigarette holder 20 provided in one embodiment of the present application.

[0198] As shown in FIG8 , the cigarette holder 20 further includes an atomizer assembly 22, which includes a heater 221. The heater 221 is made of conductive ceramic or a resistance wire with high rigidity. One end of the heater 221 is close to or in contact with the liquid guide 13, while the other end is fixed to the second housing 21. This allows the heater 221 to directly heat the aerosol matrix released from the liquid guide 13.

[0199] Please refer to Figure 9 for another schematic structural diagram of a cigarette rod 20 provided in one embodiment of the present application, and to Figure 10 for a schematic cross-sectional structural diagram of a cigarette rod 20 provided in one embodiment of the present application. The cigarette rod 20 shown in Figures 9 and 10 matches the cigarette cartridge 10 shown in Figures 2 and 3 of the present application. Figures 9 and 10 are schematic structural diagrams of the cigarette rod 20 in different directions. To facilitate the relationship between Figures 9 and 10, a third direction 003 is provided that is perpendicular to both the first direction 001 and the second direction 002.

[0200] As shown in Figures 9 and 10, the cigarette holder 20 further includes an atomizer assembly 22, wherein the atomizer assembly 22 includes a heater 221 and a diffuser 222. The diffuser 222 is in contact with the second end 13b of the liquid guide 13, and the heater 221 is fixed to the surface of the diffuser 222 away from the liquid guide 13 to heat the diffuser 222.

[0201] The diffuser 222 is made of an insulating, heat-conductive material. It is understood that the heat from the heater 221 is transferred via the diffuser 222 to the second end 13b of the liquid-guiding member 13, thereby atomizing the aerosol matrix within the liquid-guiding member 13 and allowing the aerosol matrix to be released from the sidewall 131. In another embodiment, the heater 221 can also be disposed between the liquid-guiding member and the diffuser 222, and affixed to the liquid-guiding member 13, to directly heat the aerosol matrix within the liquid-guiding member 13. Simultaneously, the diffuser 222 can also absorb the heat from the heater 221 and transfer it to the liquid-guiding member 13, thereby increasing the heating area of ​​the second end 13b of the liquid-guiding member 13 provided by the atomizing assembly 22.

[0202] The diffuser 222 has a porous structure. It is understood that the aerosol matrix can also enter the diffuser 222 and be absorbed by the diffuser 222. The heat from the corresponding heating element 221 acts on the second end 13b of the liquid-guiding element 13 while also acting on the aerosol matrix absorbed by the diffuser 222, causing it to be atomized into an aerosol.

[0203] It can be understood that the diffuser 222 has a porous structure and is made of insulating heat-conductive material. While ensuring the atomization effect of the heating element 221 on the aerosol matrix in the second end 13b of the liquid-guiding element 13, it can also prevent the un-atomized aerosol matrix from overflowing from between the second end 13b and the diffuser 222, thereby improving the user experience.

[0204] Furthermore, since the heating element 221 is typically made of a relatively low-rigidity resistance wire capable of generating heat, or a metal material is directly evaporated onto the diffuser 222, it is understood that the provision of the diffuser 222 can not only ensure the heating function of the heating element 221 but also achieve positional control of the heating element 221.

[0205] In one embodiment, the heating element 221 is made of metal.

[0206] In one embodiment, the heating element 221 is a resistive layer. In one embodiment, as shown in Figures 9 and 10, the second housing 21 further comprises a bottom cover 212, which is secured to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. It will be appreciated that external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol released from the sidewall 131 of the liquid guide 13.

[0207] In one embodiment, as shown in FIG9 and FIG10 , the cigarette rod 20 further includes a push rod 231 , one end of which is fixed to the diffuser 222 and spaced apart from the heating element 221 , and the other end of the push rod 231 extends out of the second shell 21 .

[0208] As shown in FIG1 , when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 231 passes through the guide hole 132 of the liquid guide member 13 and extends into the liquid outlet 122 , and pushes open the switch assembly 14 to release the aerosol matrix in the oil storage tank 12 .

[0209] In another embodiment, as shown in Figures 11 and 12, the push rod 231 is not provided on the cigarette rod 20, and the diffuser 222 is directly attached to the second end 13b of the liquid guide 13. The cigarette rod 20 shown in Figures 10 and 11 matches the cigarette cartridge 10 shown in Figures 4 and 5 of this application.

[0210] In one embodiment, as shown in Figures 9 to 12, the cigarette rod 20 further includes a battery 24, which is fixed to one end of the bottom cover 212 facing the first opening 211, and two poles of the battery 24 are electrically connected to the heating element 221 to provide electrical energy to the heating element 221.

[0211] At the same time, in the first direction 001, the battery 24 is spaced apart from the bottom cover 212. In the third direction 003, the battery 24 is also spaced apart from the second housing 21. The gaps between the battery 24 and the bottom cover 212, and between the battery 24 and the second housing 21, form an air intake channel 32. As will be appreciated, external air can be transmitted through the air intake hole 2121, through the air intake channel 32, to the first opening 211, and into the atomization chamber 33.

[0212] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the battery 24 and the diffuser 222. The fixing plate 213 is provided with a communication hole 2131, so that the air entering through the air inlet hole 2121 can be discharged from the communication hole 2131 via the air inlet channel 32.

[0213] In one embodiment, as shown in Figures 9-12 , the cigarette rod 20 further includes a positioning rod 232 , one end of which is fixedly connected to the diffuser 222 , and the other end of which extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the atomizer assembly 22 .

[0214] In one embodiment, as shown in FIG. 9 to FIG. 12 , the push rod 231 and the positioning rod 232 may be provided as an integral structure.

[0215] In one embodiment, as shown in Figures 9 to 12, the cigarette rod 20 further includes a conductive column 251 and a connecting wire 252. One end of the conductive column 251 is in contact with the heating element 221 and is conductive thereto. The other end of the conductive column 251 is fixed to and passes through the fixing plate 213, and is electrically connected to the two poles of the battery 24 through a connecting wire 252.

[0216] It can be understood that the electric energy inside the battery 24 is transmitted to the corresponding connecting wires 252 via the two poles, and then transmitted to the heating element 221 via the connecting wires 252 and the conductive column 251 in sequence, thereby realizing the atomization function of the cigarette rod 20.

[0217] In one embodiment, as shown in Figures 9-12, the cigarette holder 20 further includes a sensor 261. The bottom cover 212 is also provided with a sensing hole 2122. The sensing hole 2122 communicates between the outside air and the air inlet passage 32. The sensor 261 is fixedly attached to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 261 is electrically connected to a terminal of the battery 24, and the other end is electrically connected to a connecting wire 252.

[0218] When external air enters the air inlet channel 32 through the air inlet hole 2121, some air also enters the air inlet channel 32 through the sensing air hole 2122. This air can trigger the sensor 261 to connect the battery 24, the terminal, and the connecting wire 252, thereby realizing the current transmission between the battery 24 and the heating element 221, and realizing the atomization function of the cigarette rod 20.

[0219] When external air does not enter the air inlet passage 32 through the sensing air holes 2122, the sensor 261 disconnects the electrical connection between the battery 24 and the connecting wire 252. It is understood that the cigarette holder 20 of the present application can utilize the user's puffing action to switch the current between the battery 24 and the heating element 221, thereby controlling the heat generated by the heating element 221, thereby improving the user experience.

[0220] In one embodiment, as shown in Figures 9-12, the cigarette holder 20 further includes a buffer member 262, which is placed between the battery 24 and the bottom cover 212, and the sensor 261 is fixed to the buffer member 262. The buffer member 262 is provided with an air hole (not shown) to connect the air inlet channel 32 and the air inlet hole 2121.

[0221] It can be understood that the setting of the buffer member 262 not only meets the airflow transmission requirements at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 24 and the sensor 261, reducing the impact of external forces on the battery 24 and the sensor 261, and ensuring the atomization function of the cigarette rod 20 of the present application.

[0222] In one embodiment, as shown in Figures 9 to 12, the cigarette rod 20 further includes a second seal 27, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 24 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 24 and ensuring the use of the electronic cigarette 100 of the present application.

[0223] In the prior art, electronic cigarettes typically consist of a cartridge and a stem. The cartridge contains an aerosol matrix. When the cartridge and stem are connected, the battery in the stem electrically connects to the atomizer assembly inside the cartridge, which heats the aerosol matrix inside the cartridge and releases it as an aerosol.

[0224] However, in existing technologies, a single cigarette holder is typically equipped with multiple corresponding cigarette cartridges, and in existing technologies, the cigarette cartridges typically utilize an atomizer assembly to seal the aerosol matrix. Since the atomizer assembly typically has a porous structure, the aerosol matrix may leak during the transportation of the cigarette cartridge, thereby affecting the user experience.

[0225] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette cartridge with improved sealing performance, and an electronic cigarette including the electronic cigarette cartridge, which specifically includes the following technical solutions.

[0226] In the first aspect, an embodiment of the present application provides a cartridge for an electronic cigarette, comprising a first shell and a switch assembly, wherein the first shell is provided with an oil storage tank and a liquid outlet hole connected thereto, and the oil storage tank is used to store an aerosol matrix; the switch assembly comprises a connector and a sealing plug, wherein one end of the connector is connected to the first shell, and the other end of the connector is connected to the sealing plug, and the connector is made of an elastic material so that the sealing plug has a tendency to block the liquid outlet hole.

[0227] The cigarette cartridge of the present application is provided with an oil storage tank storing an aerosol matrix, and a liquid outlet is provided on the oil storage tank so that the aerosol matrix can flow out of the opening through the liquid outlet, thereby ensuring the release of the aerosol matrix by the cigarette cartridge of the present application.

[0228] The cigarette cartridge of the present application also provides a connecting piece made of elastic material, and one end of the connecting piece is fixed to the oil storage tank, and the other end extends toward the liquid outlet, and a sealing plug is provided, so that the elastic force of the connecting piece can drive the sealing plug to cover the liquid outlet to seal the oil storage tank, thereby improving the sealing performance of the cigarette cartridge of the present application for the aerosol matrix.

[0229] In one embodiment, the connecting piece and the sealing plug are integrally formed.

[0230] In one embodiment, the first shell includes a sealing plate and a shell body, the sealing plate and the shell body enclose an oil storage tank, the sealing plate is located on the side of the oil storage tank away from the liquid outlet, and one end of the connecting piece is connected to the sealing plate.

[0231] In one embodiment, the elastic modulus of the sealing plate is greater than the elastic modulus of the connecting member.

[0232] In one embodiment, the connecting member is integrally formed with the sealing plate.

[0233] In one embodiment, the oil storage tank includes a guide structure, which is arranged at one end of the liquid outlet close to the interior of the oil storage tank. The guide structure is conical, and compared with the end of the guide structure with a smaller cross-section, the end of the conical guide structure with a larger cross-section is far away from the liquid outlet.

[0234] In one embodiment, the cigarette cartridge includes a liquid guiding member, which is arranged on the side of the liquid outlet away from the oil storage tank. The liquid guiding member has a porous structure and is used to precipitate the aerosol matrix in the oil storage tank.

[0235] In one embodiment, the cigarette cartridge includes a third shell, which accommodates the first shell and is spaced apart from the first shell to form an air outlet channel. The third shell includes an air outlet hole, which is located on the side of the oil storage tank away from the liquid outlet hole. The air outlet channel connects the liquid outlet hole and the air outlet hole.

[0236] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge, wherein the cigarette rod comprises a heating assembly and a push rod, wherein the push rod is used to extend into the liquid outlet to push the switch assembly, and the heating assembly is used to heat the aerosol matrix.

[0237] In one embodiment, the heating assembly includes a diffuser and a heating element, and the push rod and the heating element are both fixed to the diffuser.

[0238] In one embodiment, the diffuser is made of insulating material and has thermal conductivity. The diffuser is used to increase the heating area of ​​the heating assembly.

[0239] In one embodiment, the diffuser has a porous structure.

[0240] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette cartridge provided in the first aspect of the present application, it also has the beneficial effect of improving the sealing performance.

[0241] Please refer to FIG. 13 , which is a schematic structural diagram of an electronic cigarette 100 provided in another embodiment of the present application, and please refer to FIG. 14 , which is another schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0242] As shown in Figures 13 and 14, the electronic cigarette 100 of the present application includes a cigarette cartridge 10 and a cigarette rod 20. The cigarette cartridge 10 includes a first shell 111, and the cigarette rod 20 includes a second shell 21. The first shell 111 contains an oil storage tank 12, which stores an aerosol matrix. The second shell 21 has a first opening 211. The cigarette cartridge 10 can partially extend into the first shell 111 through the first opening 211.

[0243] The electronic cigarette 100 of the present application also includes an air circuit 30, which connects two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposite sides of the electronic cigarette 100, allowing external air to enter from the other side of the electronic cigarette 100. The air is mixed with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and then enters the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0244] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, forming an atomization chamber 33 between the cigarette cartridge 10 and the cigarette rod 20. The air inlet channel 31 is located in the second shell 21, and the air outlet channel 32 is located in the first shell 111. The air inlet channel 31 communicates between the air inlet hole 2121 of the cigarette rod 20 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 1121 and the atomization chamber 33.

[0245] As will be understood, when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 31 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the second housing 21 flows toward the heating assembly 22 of the cigarette rod 20, absorbing the heat generated by the heating assembly 22 and atomizing into an aerosol. The aerosol mixes with the external air and, as the user inhales, flows along the air outlet channel 32 from the air outlet 1121 into the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0246] Specifically, please refer to FIG15 , which shows a schematic diagram of the structure of the cigarette cartridge 10 provided in one embodiment of the present application, and FIG16 , which shows an exploded schematic diagram of the cigarette cartridge 10 provided in one embodiment of the present application. In conjunction with FIG13 and FIG14 , for ease of description, the cigarette cartridge 10 and cigarette rod 20 in FIG13 are arranged in a first direction 001 , with a second direction 002 perpendicular to the first direction 001 .

[0247] As shown in Figures 13-16 , the cigarette cartridge 10 of the present application further includes an oil storage tank 12 , which is housed within the first housing 111 and is used to store aerosol substrate. A liquid outlet 121 is provided in the oil storage tank 12 , connecting the oil storage tank 12 with the external environment so that the aerosol substrate stored in the oil storage tank 12 can flow out of the oil storage tank 12 through the liquid outlet 121 .

[0248] The cigarette cartridge 10 also includes a switch assembly 13, which includes a connector 131 and a sealing plug 132. Both the connector 131 and the sealing plug 132 are housed within the oil storage bin 12. One end of the connector 131 is fixed to the end of the oil storage bin 12 away from the liquid outlet 121, while the other end extends toward the liquid outlet 121 and is fixedly connected to the sealing plug 132.

[0249] The connecting member 131 is made of elastic material. It is understandable that the elastic force of the connecting member 131 can act on the sealing plug 132, causing the sealing plug 132 to move toward the liquid outlet 121 and cover the liquid outlet 121, thereby achieving sealing of the oil storage tank 12.

[0250] As shown in FIG13 , when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 23 of the cigarette rod 20 can extend into the liquid outlet 121 and push the sealing plug 132 , causing the connecting member 131 to be compressed along the first direction 001 , thereby releasing the aerosol matrix.

[0251] On the other hand, as shown in FIG14 , when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 23 of the cigarette rod 20 can extend into the liquid outlet 121 and push the sealing plug 132 , and can also cause the connecting member 131 to deflect along the second direction 002 , thereby releasing the aerosol matrix.

[0252] It is understood that the connector 131, made of an elastic material, can not only ensure the sealing of the oil storage tank 12, but also cooperate with the push rod 23 to release the aerosol matrix. At the same time, when the push rod 23 is withdrawn, the elastic force of the connector 131 can also enable the sealing plug 132 to continue to cover the liquid outlet 121, thereby ensuring the sealing of the oil storage tank 12.

[0253] In existing technology, the aerosol matrix is ​​typically directly released and atomized using an atomizer assembly. This is controlled by switching the atomizer assembly on and off with the battery inside the cigarette holder. However, when a cigarette cartridge is transported by a user and subjected to vibration, some of the aerosol matrix absorbed by the atomizer assembly may leak out, affecting the cartridge's sealing performance and impacting the user experience.

[0254] Therefore, compared with the prior art, the cigarette cartridge 10 of the present application is provided with a connecting piece 131 made of elastic material, and one end of the connecting piece 131 is fixed to the oil storage tank 12, and the other end extends toward the liquid outlet 121, and a sealing plug 132 is provided, so that the elastic force of the connecting piece 131 can drive the sealing plug 132 to cover the liquid outlet 121 to seal the oil storage tank 12.

[0255] Based on the fact that the elastic force of the connecting member 131 is relatively fixed and is difficult to change due to vibration during transportation, it can be understood that the setting of the connecting member 131 ensures that the sealing plug 132 covers the liquid outlet 121, thereby improving the sealing performance of the cigarette cartridge 10 of the present application on the aerosol matrix, thereby improving the user experience.

[0256] In one embodiment, the connecting member 131 and the sealing plug 132 are integrally formed.

[0257] In one embodiment, as shown in Figures 13-16 , the oil storage tank 12 includes a guide structure 121a, which is disposed at one end of the liquid outlet 121 near the interior of the oil storage tank 12. The guide structure 121a is conical and includes a first guide opening 1211 and a second guide opening 1212 disposed opposite each other. The first guide opening 1211 is connected to the liquid outlet 121, and the aperture of the first guide opening 1211 is smaller than that of the second guide opening 1212. That is, the end of the guide structure 121a with a larger cross-section is farther from the liquid outlet 121, while the end with a smaller cross-section is closer to the liquid outlet 121.

[0258] It is understandable that the sealing plug 132 of the switch assembly 13 can extend into the second guide opening 1212 and abut against the inner wall of the guide structure 121a to seal the first guide opening 1211 and thus the liquid outlet 121, thereby ensuring the sealing effect of the cigarette cartridge 10 on the aerosol matrix.

[0259] In one embodiment, as shown in Figures 13-16 , the sealing plug 132 of the switch assembly 13 includes a supporting portion 1321 located at one end of the sealing plug 132 near the liquid outlet 121. The supporting portion 1321 is tapered. The end of the supporting portion 1321 with a smaller cross-section is located near the liquid outlet 121 and at least partially engages with the guide structure 121a.

[0260] As can be understood, the abutting portion 1321 extends into the second guide opening 1212 and abuts against the inner wall of the guide structure 121a to seal the first guide opening 1211, thereby sealing the liquid outlet 121. This further enhances the sealing effect of the sealing plug 132 on the liquid outlet 121, further ensuring the sealing effect of the electronic cigarette 100 of the present application on the aerosol matrix.

[0261] It is understood that in another embodiment, the liquid outlet 121 is a circular hole, the abutting portion 1321 of the sealing plug 132 is conical, and the abutting portion 1321 of the sealing plug 132 can at least partially extend into the liquid outlet 121 under the elastic force of the connecting member 131 to seal the oil storage tank 12. In other embodiments, the shapes of the sealing plug 132 and the liquid outlet 121 can also be other, and this application does not specifically limit this.

[0262] In one embodiment, the sealing plug 132 can be made of elastic material, and the conical inclination angle of the liquid outlet 121 is smaller than the conical inclination angle of the sealing plug 132 . The sealing plug 132 generates elastic deformation in the liquid outlet 121 to seal the oil storage tank 12 .

[0263] In one embodiment, as shown in Figures 13-16 , the cigarette cartridge 10 of the present application further includes a partition 122, which is fixed within the first housing 111 and cooperates with the first housing 111 to form the oil storage bin 12. A liquid outlet 121 is provided on the partition 122. It will be appreciated that the aerosol substrate stored in the oil storage bin 12 can pass through the partition 122 via the liquid outlet 121.

[0264] In one embodiment, as shown in Figures 13 to 16, the first shell 111 includes a sealing plate 133 and a shell body. A sealing port 1111 is provided on the side of the shell body away from the liquid outlet 121. The sealing plate 133 is fixed to the sealing port 1111 and covers the sealing port 1111.

[0265] The sealing plate 133 cooperates with the shell body to form the oil storage tank 12. The sealing plate 133 is located on a side of the oil storage tank 12 away from the liquid outlet 121, and one end of the connecting member 131 is also connected to the sealing plate 133.

[0266] In one embodiment, the elastic modulus of the sealing plate 133 is greater than the elastic modulus of the connector 131. The larger the elastic modulus of the material, the more difficult it is for the corresponding material to deform. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 23 needs to be extended into the liquid outlet 121 and push the connector 131. It can be understood that providing a connector 131 with an elastic modulus smaller than that of the sealing plate 133 can reduce the force used by the push rod 23 to push the connector 131 when the push rod 23 pushes the connector 131 to deform, so as to facilitate user use.

[0267] In one embodiment, as shown in FIG14 , the sealing plate 133 is made of a rigid material, and the sealing plate 133, the connector 131, and the sealing plug 132 are integrally formed. It will be appreciated that in another embodiment, the connector 131 and the sealing plug 132 are integrally formed. In another embodiment, the sealing plate 133 and the connector 131 are integrally formed.

[0268] In one embodiment, as shown in Figures 13 to 16, the cigarette cartridge 10 further includes a liquid guide 14, which is fixed to the outer surface of the partition 122 away from the oil storage tank 12, and a guide hole 141 is provided through the liquid guide 14, so that the push rod 23 of the cigarette rod 20 can enter the liquid outlet 121 through the guide hole 141.

[0269] As shown in Figures 13 and 14, when the cartridge 10 and the cigarette rod 20 are assembled, the push rod 23 releases the aerosol matrix in the oil reservoir 12. This aerosol matrix can flow from the liquid outlet 121 to the liquid guide 14 and be absorbed by the liquid guide 14. The liquid guide 14 can guide the aerosol matrix toward the heating assembly 22 of the cigarette rod 20, and cooperate with the heat released by the heating assembly 22 to atomize the aerosol matrix to form an aerosol. This realizes the aerosol matrix atomization function of the electronic cigarette 100 of the present application.

[0270] In one embodiment, as shown in Figures 15 and 16 , the cigarette cartridge 10 further includes a third housing 112 . The first housing 111 is housed within the third housing 112 . The first housing 111 is further provided with an air outlet 1121 . The first and third housings 111, 112 are spaced apart from each other to form an air outlet channel 32 between the first and third housings 111, 112 . The air outlet channel 32 is also in communication with the air outlet 1121 .

[0271] It is understood that after the aerosol matrix flowing out of the liquid outlet 121 is heated and atomized by the heating assembly 22 of the cigarette rod 20, the formed aerosol can flow from the atomization chamber 33 to the air outlet 1121 through the air outlet channel 32 and be output outward from the air outlet 1121. This realizes the user's inhalation function of the electronic cigarette 100 of the present application.

[0272] Please refer to FIG17 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG18 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG13 .

[0273] As shown in Figures 13, 17, and 18, the cigarette cartridge 10 of the present application further includes a support member 15. The first shell 111 is cylindrical, and a plurality of support members 15 are provided. The plurality of support members 15 are spaced apart along the circumference of the first shell 111, and each support member 15 is fixed between the first shell 111 and the third shell 112.

[0274] A gap is left between each two adjacent support members 15 to form an air outlet channel 32. It can be understood that the mixed gas of aerosol and air entering the air outlet channel 32 from the atomization chamber 33 can be transmitted from between the two adjacent support members 15 to the air outlet hole 1121.

[0275] In one embodiment, as shown in Figures 17 and 18, the cigarette cartridge 10 further includes a liquid wick 16, which is disposed between each two adjacent support members 15 and spaced apart from at least one support member 15 to ensure that the aerosol and air mixture entering the air outlet passage 32 from the atomization chamber 33 can be discharged. The liquid wick 16 can be used to absorb condensed aerosol matrix formed during the transmission process, preventing the aerosol matrix from entering the mouth through the air outlet passage 32, thereby ensuring a good user experience.

[0276] In one embodiment, as shown in FIG16 , the cigarette cartridge 10 further includes a sealing member 17, one end of which is fixed to the partition 122, and the other end of which extends toward the liquid guide 14. The sealing member 17 is also fixedly connected to the first housing 111. The sealing member 17 is used to prevent the aerosol matrix from escaping from the gap between the liquid guide 14 and the first housing 111.

[0277] The sealing member 17 is provided with a first connecting hole 171 , a second connecting hole 172 and a third connecting hole 173 , wherein the diameter of the second connecting hole 172 is larger than that of the first connecting hole 171 and smaller than that of the third connecting hole 173 .

[0278] Along the first direction 001, the projection of the liquid outlet 121 on the sealing member 17 is received within the first connection hole 171. One end of the liquid guide member 14 extends into and is received within the third connection hole 173, while the other end of the liquid guide member 14 extends outside the third connection hole 173. The aerosol matrix flows out of the liquid outlet 121, through the first connection hole 171, into the second connection hole 172, and contacts the liquid guide member 14 located within the third connection hole 173.

[0279] Because the liquid guide 14 needs to absorb the aerosol matrix and guide it toward the heating assembly 22 before it can be atomized into an aerosol, the aerosol matrix released from the liquid outlet 121 does not stop being released due to the aerosol matrix not being atomized. It is understandable that a portion of the aerosol matrix is ​​stored in the second connection hole 172, and this portion of the aerosol matrix will diffuse outward due to the relatively larger aperture of the second connection hole 172 compared to the first connection hole 171, thereby increasing the contact area between the aerosol matrix and the liquid guide 14 and improving the liquid guide 14's efficiency in absorbing the aerosol matrix.

[0280] Because the liquid guide 14 partially exposes the sealing member 17 and is made of a porous material, it is understood that external air can also enter the second connecting hole 172 through the pores in the liquid guide 14 and achieve air pressure balance between the oil storage tank 12 and the external environment through the liquid outlet 121, ensuring smooth release of the liquid in the oil storage tank 12, thereby improving the user experience.

[0281] Please refer to Figure 19, a schematic diagram of the structure of a cigarette rod 20 provided in one embodiment of the present application, and Figure 20, a schematic diagram of the cross-sectional structure of a cigarette rod 20 provided in one embodiment of the present application. Please also refer to Figure 13. Figures 19 and 20 are schematic diagrams of the structure of the cigarette rod 20 from different directions. To facilitate the relationship between Figures 19 and 20, a third direction 003 is provided that is perpendicular to both the first direction 001 and the second direction 002.

[0282] As shown in Figures 13, 19, and 20, the cigarette holder 20 of the present application further includes a heating assembly 22. The heating assembly 22 comprises a diffuser 221 and a heater 222. The diffuser 221 is made of a porous material. When the cigarette cartridge 10 and cigarette holder 20 are assembled as one, the diffuser 221 absorbs aerosol substrate flowing from the first opening 211 into the second housing 21, preventing the inflowing aerosol substrate from flowing into the air path 30, thereby ensuring a superior user experience.

[0283] The heater 222 is fixed to the diffuser 221 to heat the diffuser 221 and atomize the aerosol matrix absorbed by the diffuser 221 into an aerosol, which is then released into the atomization chamber 33. This prevents the aerosol matrix stored in the diffuser 221 from flowing out of the diffuser 221. Simultaneously, the heat from the heater 222 can also be transferred to the liquid guide 14 to atomize the aerosol matrix within the liquid guide 14. This achieves the aerosol matrix atomization function of the cigarette holder 20 of the present application.

[0284] In one embodiment, as shown in Figures 13, 19, and 20, the heating element 222 is fixed to the surface of the diffuser 221 away from the first opening 211. When the first housing 111 and the second housing 21 are connected, the surface of the diffuser 221 facing the first opening 211 is in contact with the surface of the liquid guide 14.

[0285] As can be understood, the aerosol matrix within the oil storage tank 12 is absorbed by the liquid guide member 14 through the liquid outlet 121 and directed toward the diffuser 221. Part of the aerosol matrix is ​​atomized into aerosol and released due to the heat released by the diffuser 221 after being heated by the heater 222. Another part of the aerosol matrix flows out of the liquid guide member 14 and is absorbed by the diffuser 221. This part of the aerosol matrix is ​​atomized into aerosol and released due to the heat from the heater 222. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0286] In another embodiment, the heating element 222 is fixed to the surface of the diffuser 221 facing the first opening 211 , and the diffuser 221 has a surface partially exposed from the heating element 222 , so that the aerosol matrix flowing out of the liquid guiding element 14 can contact the diffuser 221 and be absorbed by the diffuser 221 .

[0287] When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the surface of the heating element 222 facing the first opening 211 mates with the surface of the liquid guide 14 facing away from the oil storage tank 12. The aerosol matrix in the oil storage tank 12 is absorbed by the liquid guide 14 through the liquid outlet 121 and directed toward the diffuser 221. Part of the aerosol matrix directly absorbs the heat released by the heating element 222, atomizing into an aerosol and releasing it. Another part of the aerosol matrix flows out of the liquid guide 14 and is absorbed by the diffuser 221. This part of the aerosol matrix is ​​atomized into an aerosol under the action of the heat from the heating element 222 and released. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0288] In one embodiment, the diffuser 221 is made of an insulating material and has thermal conductivity. The heat released by the heater 222 to the diffuser 221 can be diffused through the diffuser 221. Because the aerosol matrix contacts the surface of the diffuser 221, and the cross-sectional area of ​​the heater 222 is smaller than that of the diffuser 221, it can be understood that the diffuser 221 can increase the heating area of ​​the aerosol matrix by the cigarette rod 20, allowing the aerosol matrix flowing to the surface of the diffuser 221 to absorb more heat, thereby improving the atomization efficiency of the electronic cigarette 100 of the present application.

[0289] In one embodiment, both the liquid-guiding member 14 and the diffuser 221 are made of porous materials, and the porosity of the liquid-guiding member 14 is greater than that of the diffuser 221. Since the porosity is related to the liquid absorption and permeability of the material, the greater the porosity of the material, the greater the number of closed pores, the smaller the pore diameter, the stronger the liquid absorption and permeability of the material.

[0290] Since more aerosol substrate enters the liquid-guiding member 14 than the diffuser 221, it is understandable that the liquid-guiding member 14 having a higher porosity can enable the aerosol substrate released from the liquid outlet 121 to be absorbed relatively quickly, thereby ensuring the release efficiency of the aerosol substrate by the cartridge 10 of the electronic cigarette 100 of the present application.

[0291] At the same time, since the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-guiding member 14 can also diffuse into the entire liquid-guiding member 14 more quickly, thereby achieving a match between the heat released by the heating member 222 and the diffuser 221 and the amount of aerosol matrix guided toward the heating member 222, thereby ensuring the amount of aerosol released by the electronic cigarette 100 of the present application.

[0292] When some aerosol matrix overflows onto the surface of the diffuser 221, the porosity of the diffuser 221 is smaller than that of the liquid-conducting member 14. While being absorbed by the aerosol matrix 221, the aerosol matrix overflowing onto the surface of the diffuser 221 penetrates relatively slowly. Because the temperature decreases with increasing distance from the heater 222, the amount of heat absorbed by the aerosol matrix also decreases. It is understood that providing a diffuser 221 with a smaller porosity can reduce the penetration rate of the aerosol matrix, thereby extending the penetration time of the aerosol matrix, allowing the aerosol matrix to absorb more heat to atomize and form an aerosol.

[0293] That is, the matching setting of the porosity of the diffuser 221 and the liquid-conducting member 14 increases the amount of heat absorbed by the aerosol matrix from the heating element 222, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and improving the user experience of using the electronic cigarette 100 of the present application.

[0294] In one embodiment, as shown in Figures 19 and 20, the second housing 21 further includes a bottom cover 212, which is fixed to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. As will be appreciated, external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol released from the liquid guide 14.

[0295] In one embodiment, as shown in Figures 19 and 20, the cigarette rod 20 further includes a battery 25, which is fixed to one end of the bottom cover 212 facing the first opening 211, and the two poles of the battery 25 are respectively electrically connected to the heating element 222 to provide electrical energy to the heating element 222.

[0296] At the same time, in the first direction 001, the battery 25 is spaced apart from the bottom cover 212. In the third direction 003, the battery 25 is also spaced apart from the second housing 21. The gaps between the battery 25 and the bottom cover 212, and between the battery 25 and the second housing 21, form an air inlet passage 31. As will be appreciated, external air can be transmitted through the air inlet holes 2121 and the air inlet passage 31 to the atomization chamber 33.

[0297] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the battery 25 and the diffuser 221. The fixing plate 213 is provided with a communication hole 2131, so that the air entering through the air inlet hole 2121 can be discharged from the communication hole 2131 via the air inlet channel 31.

[0298] In one embodiment, the cigarette rod 20 further includes a positioning rod 24 , wherein one end of the positioning rod 24 is fixedly connected to the diffuser 221 , and the other end of the positioning rod 24 extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the diffuser 221 .

[0299] In one embodiment, as shown in FIG. 19 and FIG. 20 , the positioning rod 24 and the push rod 23 are an integral structure.

[0300] In one embodiment, as shown in Figures 19 and 20, the cigarette rod 20 further includes a conductive column 261 and a connecting wire 262. One end of the conductive column 261 is in contact with the heating element 222 for conduction, and the other end of the conductive column 261 is fixed to and passes through the fixing plate 213, and is electrically connected to the two poles of the battery 25 through a connecting wire 262 respectively.

[0301] It can be understood that the electric energy inside the battery 25 is transmitted to the corresponding connecting wires 262 via the two poles, and then transmitted to the heating element 222 via the connecting wires 262 and the conductive column 261 in turn, thereby realizing the atomization function of the cigarette rod 20.

[0302] In one embodiment, as shown in Figures 19 and 20, the cigarette holder 20 further includes a sensor 271, and the bottom cover 212 is provided with a sensing hole 2122. The sensing hole 2122 communicates between the outside air and the air inlet passage 31. The sensor 271 is fixedly connected to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 271 is electrically connected to a terminal of the battery 25, and the other end is electrically connected to a connecting wire 262.

[0303] When external air enters the air inlet channel 31 through the air inlet hole 2121, some air also enters the air inlet channel 31 through the sensing air hole 2122. This air can trigger the sensor 271 to connect the battery 25, the terminal, and the connecting wire 262, thereby realizing the current transmission between the battery 25 and the heating element 222, and realizing the atomization function of the cigarette rod 20.

[0304] When external air does not enter the air inlet passage 31 through the sensing air holes 2122, the sensor 271 disconnects the electrical connection between the battery 25 and the connecting wire 262. It is understood that the cigarette holder 20 of the present application can utilize the user's puffing action to switch the current between the battery 25 and the heating element 222, thereby controlling the heat generated by the heating element 222, thereby improving the user experience.

[0305] In one embodiment, as shown in Figures 19 and 20, the cigarette holder 20 further includes a buffer member 272, which is placed between the battery 25 and the bottom cover 212, and the sensor 271 is fixed to the buffer member 272. The buffer member 272 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 2121.

[0306] It can be understood that the setting of the buffer member 272 not only meets the airflow transmission requirements at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 25 and the sensor 271, reducing the impact of external forces on the battery 25 and the sensor 271, and ensuring the atomization function of the cigarette rod 20 of the present application.

[0307] In one embodiment, as shown in Figures 19 and 20, the cigarette rod 20 also includes a second seal 28, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 25 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 25 and ensuring the use of the electronic cigarette 100 of the present application.

[0308] It should be understood that the terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of this application, "plurality" means two or more, unless otherwise specifically defined.

[0309] In the prior art, electronic cigarettes typically consist of a cartridge and a stem. The cartridge contains an aerosol matrix. When the cartridge and stem are connected, the battery in the stem electrically connects to the atomizer assembly inside the cartridge, which heats the aerosol matrix inside the cartridge and releases it as an aerosol.

[0310] However, in existing technologies, a single cigarette holder is typically equipped with multiple corresponding cartridges. To ensure atomization of the aerosol matrix, the cartridges typically utilize a porous atomizer assembly. However, during transportation, the aerosol matrix may leak through the pores, impacting the user experience.

[0311] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette cartridge with improved sealing performance, and an electronic cigarette including the electronic cigarette cartridge, which specifically includes the following technical solutions.

[0312] In the first aspect, an embodiment of the present application provides a cartridge for an electronic cigarette, comprising a first shell and a sealing plug, wherein the first shell is provided with an oil storage tank and a liquid outlet connected to the oil storage tank, and the oil storage tank is used to store an aerosol matrix; the sealing plug is arranged in the oil storage tank, and the sealing plug is elastically connected to the first shell, and the first shell is provided with a guide structure, and the sealing plug has a tendency to seal the liquid outlet along the guide structure under the action of elastic force.

[0313] The cigarette cartridge of the present application is provided with an oil storage tank storing an aerosol matrix, and a liquid outlet is provided on the oil storage tank so that the aerosol matrix can flow out of the opening through the liquid outlet, thereby ensuring the release of the aerosol matrix by the cigarette cartridge of the present application.

[0314] The cigarette cartridge of the present application is further provided with a guide structure, and the sealing plug is able to have a tendency to seal the liquid outlet hole along the guide structure under the action of elastic force, so that the sealing plug can extend into the liquid outlet hole under the action of elastic force to seal the oil storage tank, thereby improving the sealing performance of the cigarette cartridge of the present application.

[0315] In one embodiment, a guide structure is provided at the end of the liquid outlet facing the inner side of the oil storage tank. The guide structure is conical, and the end with a larger cross-section of the guide structure is farther away from the liquid outlet than the end with a smaller cross-section of the guide structure.

[0316] In one embodiment, the cigarette cartridge includes a connecting piece, which is located between the first shell and the sealing plug. The connecting piece is elastic and is used to provide elastic force to the sealing plug.

[0317] In one embodiment, the connecting member is a tension spring, one end of the connecting member is fixed to the periphery of the liquid outlet, and the other end is fixedly connected to the sealing plug, which passes through the interior of the connecting member and partially extends into the guide structure.

[0318] In one embodiment, the connecting member is a compression spring, one end of which is fixed to the inner wall of the oil storage tank away from the liquid outlet, and the other end of the connecting member abuts against the sealing plug and drives the sealing plug to at least partially extend into the guide structure.

[0319] In one embodiment, the sealing plug is conical, and the end of the conical sealing plug with a smaller cross-section is closer to the liquid outlet than the end with a larger cross-section of the sealing plug. The conical outer wall of the sealing plug is at least partially fitted with the conical inner wall of the guide structure to seal the oil storage tank.

[0320] In one embodiment, the sealing plug is made of elastic material, and the cone inclination angle of the guide structure is smaller than the cone inclination angle of the sealing plug. The sealing plug generates elastic deformation in the guide structure to seal the oil storage tank.

[0321] In one embodiment, the cigarette cartridge includes a partition, which is located in the first shell and is surrounded by the first shell to form an oil storage tank, and the liquid outlet is provided on the partition.

[0322] In one embodiment, the first shell further includes a liquid guide member, which is located on a side of the partition away from the oil storage tank and is fixedly spaced apart from the partition. The liquid guide member is used to prevent the aerosol matrix from flowing out of the liquid outlet.

[0323] In one embodiment, the liquid-conducting member has a porous structure, and the aerosol matrix is ​​immersed in the liquid-conducting member and permeates outward.

[0324] In one embodiment, the first shell further includes a sealing member, which surrounds the periphery of the partition and extends toward the liquid guiding member, and is configured to guide the aerosol matrix to flow toward the liquid guiding member.

[0325] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge, wherein the cigarette rod comprises a push rod, which is used to extend into the liquid outlet to push a sealing plug to release an aerosol matrix.

[0326] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette cartridge provided in the first aspect of the present application, it also has the beneficial effect of improving the sealing performance.

[0327] Please refer to FIG. 21 for a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application, and please refer to FIG. 22 for another schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0328] As shown in Figures 21 and 22, the electronic cigarette 100 of the present application includes a cigarette cartridge 10 and a cigarette rod 20. The cigarette cartridge 10 includes a first shell 111, and the cigarette rod 20 includes a second shell 21. The first shell 111 contains an oil storage tank 12, which stores an aerosol matrix. The second shell 21 has a first opening 211. The cigarette cartridge 10 can partially extend into the first shell 111 through the first opening 211.

[0329] The electronic cigarette 100 of the present application also includes an air circuit 30, which connects two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposite sides of the electronic cigarette 100, allowing external air to enter from the other side of the electronic cigarette 100. The air is mixed with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and then enters the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0330] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, forming an atomization chamber 33 between the cigarette cartridge 10 and the cigarette rod 20. The air inlet channel 31 is located in the second shell 21, and the air outlet channel 32 is located in the first shell 111. The air inlet channel 31 communicates between the air inlet hole 2121 of the cigarette rod 20 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 1121 of the cigarette cartridge 10 and the atomization chamber 33.

[0331] As will be understood, when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 31 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the second housing 21 flows toward the heating element 23 of the cigarette rod 20, absorbing the heat generated by the heating element 23 and atomizing into an aerosol. The aerosol mixes with the external air and, as the user inhales, flows along the air outlet channel 32 from the air outlet 1121 into the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0332] Specifically, please refer to FIG23 for a schematic structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG24 for an exploded schematic diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG21 and FIG22 for details. FIG23 and FIG24 both depict the cigarette cartridge 10 shown in FIG21 . For ease of description, the arrangement direction of the cigarette cartridge 10 and cigarette rod 20 in FIG21 is set to a first direction 001, with a second direction 002 perpendicular to the first direction 001.

[0333] As shown in Figures 21-24, the cigarette cartridge 10 of the present application further includes an oil storage tank 12, which is housed within the first housing 111 and is used to store aerosol substrate. A liquid outlet 121 is provided on the oil storage tank 12, connecting the oil storage tank 12 with the external environment so that the aerosol substrate stored in the oil storage tank 12 can flow out of the oil storage tank 12 through the liquid outlet 121.

[0334] The cartridge 10 also includes a switch assembly 13. The switch assembly 13 includes a sealing plug 131, which is housed within the oil storage bin 12 and elastically connected to the first housing 111. Under the action of elastic force, the sealing plug 131 can partially extend into the liquid outlet 121 to cover the liquid outlet 121, thereby sealing the oil storage bin 12.

[0335] As shown in Figure 21, a guide structure 121a is also provided on the first housing 111. The guide structure 121a is located at the end of the liquid outlet 121 facing the inner side of the oil storage tank 12. The guide structure 121a is conical and includes a first guide opening 1211 and a second guide opening 1212 disposed opposite each other. The first guide opening 1211 is connected to the liquid outlet 121, and the aperture of the first guide opening 1211 is smaller than that of the second guide opening 1212. That is, the end of the guide structure 121a with the larger cross-section is away from the liquid outlet 121, while the end with the smaller cross-section is closer to the liquid outlet 121.

[0336] When the cigarette cartridge 10 and cigarette rod 20 are disconnected, the sealing plug 131 can move toward the liquid outlet 121 within the guide structure 121a under the action of elastic force. It can be understood that the conical guide structure 121a can guide the sealing plug 131 toward the liquid outlet 121, and the side wall of the sealing plug 131 abuts against the conical inner wall of the guide structure 121a, thereby sealing the oil storage tank 12.

[0337] It can be understood that, as shown in Figures 21 and 22, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 of the cigarette rod 20 can extend into the liquid outlet 121 and push the sealing plug 131 to move along the first direction 001, thereby releasing the aerosol matrix.

[0338] 21 and 22 , the switch assembly 13 further includes a connector 132 . The connector 132 is located between the oil storage tank 12 and the sealing plug 131 . The connector 132 is elastic and provides elastic force to the sealing plug 131 to drive the sealing plug 131 into the liquid outlet 121 along the first direction 001 .

[0339] As shown in FIG21 , the connecting member 132 is configured as a compression spring, one end of which is fixed to the inner wall of the oil storage tank 12 away from the liquid outlet 121, and the other end of which abuts against the sealing plug 131. It is understood that the elastic force within the connecting member 132 can drive the sealing plug 131 to move in the first direction 001 away from the connecting member 132 and extend into the guide structure 121a to cover the liquid outlet 121, thereby sealing the oil storage tank 12.

[0340] As shown in Figure 21, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 of the cigarette rod 20 extends into the liquid outlet 121 and abuts against the sealing plug 131. The push rod 24 can push the sealing plug 131 to move along the first direction 001 away from the liquid outlet 121, thereby compressing the connecting piece 132 to open the liquid outlet 121 and release the aerosol matrix in the oil storage tank 12.

[0341] When the cigarette cartridge 10 and cigarette rod 20 are disconnected, the push rod 24 of the cigarette rod 20 exits the liquid outlet 121. The elastic force stored in the connecting member 132 drives the sealing plug 131 to move in the first direction 001 toward the liquid outlet 121 and into the guide structure 121a until the side wall of the sealing plug 131 abuts against the tapered inner wall of the guide structure 121a, thereby shielding the liquid outlet 121 and sealing the oil storage tank 12.

[0342] On the other hand, as shown in FIG22 , the connecting member 132 can also be configured as a compression spring, with one end of the connecting member 132 fixed to the periphery of the liquid outlet 121 and the other end fixedly connected to the sealing plug 131. It is understood that the elastic force within the connecting member 132 can drive the sealing plug 131 to extend into the interior of the connecting member 132 along the first direction 001 and into the guide structure 121a, thereby shielding the liquid outlet 121 and thus sealing the oil storage tank 12.

[0343] As shown in Figure 22, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 of the cigarette rod 20 extends into the liquid outlet 121 and abuts against the sealing plug 131. The push rod 24 can push the sealing plug 131 to move along the first direction 001 away from the liquid outlet 121, thereby stretching the connecting piece 132 to open the liquid outlet 121 and release the aerosol matrix in the oil storage tank 12.

[0344] When the cigarette cartridge 10 and the cigarette rod 20 are disconnected, the push rod 24 of the cigarette rod 20 exits the liquid outlet 121. The elastic force stored in the connecting member 132 drives the sealing plug 131 to move in the first direction 001 toward the liquid outlet 121 and into the guide structure 121a until the side wall of the sealing plug 131 abuts against the tapered inner wall of the guide structure 121a, thereby sealing the oil storage tank 12.

[0345] As can be understood, the switch assembly 13, which includes the sealing plug 131 and the connecting member 132, can not only seal the oil storage tank 12 but also cooperate with the push rod 24 to release the aerosol matrix. Furthermore, when the push rod 24 is withdrawn, the elastic force of the connecting member 132 allows the sealing plug 131 to continue extending into the guide structure 121a and cover the liquid outlet 121, thereby ensuring the sealing of the oil storage tank 12.

[0346] In existing technology, the aerosol matrix is ​​typically directly released and atomized using an atomizer assembly. This is controlled by switching the atomizer assembly on and off with the battery inside the cigarette holder. However, when a cigarette cartridge is transported by a user and subjected to vibration, some of the aerosol matrix absorbed by the atomizer assembly may leak out, affecting the cartridge's sealing performance and impacting the user experience.

[0347] Therefore, compared with the prior art, the cigarette cartridge 10 of the present application is provided with a sealing plug 131 elastically connected to the first shell 111 and a conical guide structure 121a, so that the elastic force of the connecting member 132 can drive the sealing plug 131 to extend into the conical guide structure 121a, and under the guidance of the conical inner wall of the guide structure 121a, the liquid outlet 121 is covered to seal the oil storage tank 12.

[0348] The sealing plug 131 is elastically connected to the first housing 111 via the connector 132, the elastic force of the connector 132 is relatively constant, and the tapered inner wall can restrict the movement of the switch assembly 13 in the second direction 002. It can be understood that the arrangement of the tapered guide structure 121a and the coordination with the switch assembly 13 ensure that the switch assembly 13 shields the liquid outlet 121, thereby improving the sealing performance of the cigarette cartridge 10 of the present application with respect to the aerosol matrix, thereby enhancing the user experience.

[0349] In one embodiment, as shown in Figures 21-24, the sealing plug 131 is conical, with the end of the conical sealing plug 131 having a smaller cross-sectional area being closer to the liquid outlet 121. The guide structure 121a is also conical, with the end of the conical guide structure 121a having the largest cross-sectional area being closer to the sealing plug 131. It is understood that when the cigarette cartridge 10 and the cigarette rod 20 are not connected, the elastic force of the connector 132 pushes the sealing plug 131 toward the liquid outlet 121 and partially extends into the guide structure 121a.

[0350] The tapered outer wall of the sealing plug 131 extending into the guide structure 121a and the tapered inner wall of the guide structure 121a fit together, thereby achieving sealing of the oil storage tank 12 by the sealing plug 131, further improving the sealing performance of the cigarette cartridge 10 of the present application for the aerosol matrix.

[0351] It is understood that in another embodiment, the sealing plug 131 is cylindrical, the guide structure 121a is conical, and the sealing plug 131 can at least partially extend into the guide structure 121a under the elastic force of the connecting member 132 to seal the oil storage tank 12. In other embodiments, the shape of the sealing plug 131 can also be other, and this application does not specifically limit this.

[0352] In one embodiment, the sealing plug 131 is made of elastic material, and the conical inclination angle of the liquid outlet hole 121 is smaller than the conical inclination angle of the sealing plug 131 , so that the sealing plug 131 generates elastic deformation in the liquid outlet hole 121 to seal the oil storage tank.

[0353] In one embodiment, as shown in Figures 21-24, the cigarette cartridge 10 of the present application further includes a partition 122, which is fixed within the first housing 111 and cooperates with the first housing 111 to form the oil storage bin 12. A liquid outlet 121 is provided on the partition 122. As will be appreciated, the aerosol substrate stored in the oil storage bin 12 can flow out through the liquid outlet 121 and through the partition 122.

[0354] In one embodiment, as shown in Figures 21-24, the cigarette cartridge 10 of the present application further includes a liquid guide 14, which is located on a side of the partition 122 away from the oil storage bin 12 along the first direction 001 and is fixedly spaced from the partition 122. During the separation process between the cigarette cartridge 10 and the cigarette rod 20, some aerosol matrix may leak from the gap between the switch assembly 13 and the liquid outlet 121.

[0355] It can be understood that the provision of the liquid guide 14 blocks the possibility of this part of the aerosol matrix flowing out, further improving the sealing performance of the cigarette cartridge 10 of the present application to the aerosol matrix and enhancing the user experience.

[0356] The liquid guide 14 is made of a porous material so that the aerosol matrix flowing into the liquid guide 14 can be absorbed by the liquid guide 14 and penetrate toward the opening. Because the pores within the liquid guide 14 have a certain liquid storage capacity, it can be understood that the liquid guide 14 can store leaked aerosol matrix and provide aerosol matrix for the electronic cigarette 100 of this application when the cigarette cartridge 10 and cigarette rod 20 are assembled as one.

[0357] It is understood that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix can first be absorbed by the liquid guide 14 and then permeate outward. At the same time, the aerosol matrix that permeates outward can also absorb the heat of the heating element 23 of the cigarette rod 20, thereby being atomized into aerosol.

[0358] The spacing between the liquid-guiding member 14 and the partition 122 also allows aerosol substrate leaking from the liquid outlet 121 to flow into the gap between the liquid-guiding member 14 and the partition 122. Given the fluidity of the aerosol substrate, it is understandable that the gap between the liquid-guiding member 14 and the partition 122 allows the aerosol substrate to diffuse in all directions along the second direction 002, thereby increasing the contact area between the aerosol substrate and the liquid-guiding member 14 and improving the efficiency of the liquid-guiding member 14 in absorbing the leaked aerosol substrate. This avoids leakage caused by excessive aerosol substrate accumulation.

[0359] At the same time, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the spacing between the liquid guide 14 and the partition 122 can also improve the absorption efficiency of the liquid guide 14 for the released aerosol matrix, thereby improving the atomization efficiency of the electronic cigarette 100 of the present application.

[0360] On the other hand, the liquid guide member 14 is further provided with a guide hole 141. The guide hole 141 is used to expose the liquid outlet 121, so that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 of the cigarette rod 20 can pass through the guide hole 141 and extend into the liquid outlet 121, thereby ensuring the push rod 24's function of releasing the aerosol matrix in the cigarette cartridge 10.

[0361] In one embodiment, as shown in Figures 21 to 24, the first shell 111 further includes a sealing member 115, which surrounds the periphery of the partition 122 and extends toward the liquid guide member 14. The sealing member 115 cooperates with the partition 122 and the liquid guide member 14 to form a relatively sealed space between the liquid guide member 14 and the partition 122. When the aerosol matrix flows out from the liquid outlet 121, it may flow to the side wall of the sealing member 115 due to the influence of the posture of the cigarette cartridge 10. It can be understood that the setting of the sealing member 115 allows this part of the aerosol matrix to flow toward the liquid guide member 14 under the guidance of the sealing member 115, thereby preventing the leakage of the aerosol matrix. This further improves the sealing performance of the cigarette cartridge 10 of the present application.

[0362] In one embodiment, as shown in Figures 21-24 , a sealing opening 1111 is provided on a side of the first housing 111 away from the liquid outlet 121. The switch assembly 13 further includes a sealing plate 133 secured to and covering the sealing opening 1111. The first housing 111, the partition 122, and the sealing plate 133 cooperate to form the oil storage tank 12. As shown in Figure 21 , the connector 132 is secured to the sealing plate 133.

[0363] In one embodiment, as shown in Figures 23 and 24, the cigarette cartridge 10 further includes a third housing 112. The first housing 111 is housed within the third housing 112. The third housing 112 further defines an air outlet 1121. The first and third housings 111, 112 are spaced apart to form an air outlet channel 32. The air outlet channel 32 is also connected to the air outlet 1121.

[0364] It is understood that after the aerosol matrix flowing out of the liquid outlet 121 is heated and atomized by the heating element 23 of the cigarette rod 20, the formed aerosol can flow from the atomization chamber 33 to the air outlet 1121 through the air outlet channel 32 and be discharged outward from the air outlet 1121. This realizes the user's inhalation function of the electronic cigarette 100 of the present application.

[0365] Please refer to FIG25 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG26 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG21 .

[0366] As shown in Figures 21, 25, and 26, the cigarette cartridge 10 of the present application further includes a support member 15. The first shell 111 is cylindrical, and a plurality of support members 15 are provided. The plurality of support members 15 are spaced apart along the circumference of the first shell 111, and each support member 15 is fixed between the first shell 111 and the third shell 112.

[0367] A gap is left between each two adjacent support members 15 to form an air outlet channel 32. It can be understood that the mixed gas of aerosol and air entering the air outlet channel 32 from the atomization chamber 33 can be transmitted from between the two adjacent support members 15 to the air outlet hole 1121.

[0368] In one embodiment, as shown in Figures 25 and 26, the cigarette cartridge 10 further includes a liquid wick 16, which is disposed between each two adjacent support members 15 and spaced apart from at least one support member 15 to ensure that the mixed gas of aerosol and air entering the outlet passage 32 from the atomization chamber 33 can be discharged. The liquid wick 16 can be used to absorb the aerosol matrix condensed during the transmission process, preventing the aerosol matrix from entering the mouth through the outlet passage 32, thereby ensuring a good user experience.

[0369] Please refer to Figure 27, a schematic diagram of the structure of a cigarette rod 20 provided in one embodiment of the present application, and Figure 28, a schematic diagram of the cross-sectional structure of a cigarette rod 20 provided in one embodiment of the present application. Please also refer to Figure 21. Figures 27 and 28 are schematic diagrams of the structure of the cigarette rod 20 from different directions. To facilitate the relationship between Figures 27 and 28, a third direction 003 is provided that is perpendicular to both the first direction 001 and the second direction 002.

[0370] As shown in Figures 21, 27, and 28, the cigarette holder 20 of the present application further includes a diffuser 22 and a heater 23. The diffuser 22 is made of a porous material. When the cigarette cartridge 10 and cigarette holder 20 are assembled, the diffuser 22 absorbs aerosol substrate flowing into the second housing 21 from the first opening 211, preventing the inflowing aerosol substrate from flowing into the air path 30, thereby ensuring a good user experience.

[0371] The heater 23 is fixed to the diffuser 22 to heat the diffuser 22 and atomize the aerosol matrix absorbed by the diffuser 22 into an aerosol, which is then released into the atomization chamber 33, thereby preventing the aerosol matrix stored in the diffuser 22 from flowing out of the diffuser 22. Simultaneously, the heat from the heater 23 can also be transferred to the liquid guide 14 to atomize the aerosol matrix within the liquid guide 14. This achieves the aerosol matrix atomization function of the cigarette holder 20 of the present application.

[0372] In one embodiment, as shown in Figures 21, 27, and 28, the heater 23 is fixed to the surface of the diffuser 22 away from the first opening 211. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the surface of the diffuser 22 facing the first opening 211 is in contact with the surface of the liquid guide 14.

[0373] As can be understood, the aerosol matrix within the oil storage tank 12 is absorbed by the liquid guide member 14 through the liquid outlet 121 and directed toward the diffuser 22. Part of the aerosol matrix is ​​atomized into aerosol and released due to the heat released by the diffuser 22 after being heated by the heater 23. Another part of the aerosol matrix flows out of the liquid guide member 14 and is absorbed by the diffuser 22. This part of the aerosol matrix is ​​atomized into aerosol and released due to the heat from the heater 23. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0374] In another embodiment, the heater 23 is fixed to the surface of the diffuser 22 facing the first opening 211 , and the diffuser 22 has a surface partially exposed from the heater 23 , so that the aerosol matrix flowing out of the liquid guide 14 can contact the diffuser 22 and be absorbed by the diffuser 22 .

[0375] When the cigarette cartridge 10 and cigarette rod 20 are assembled, the surface of the heating element 23 facing the first opening 211 mates with the surface of the liquid guide 14. The aerosol matrix within the oil reservoir 12 is absorbed by the liquid guide 14 through the liquid outlet 121 and directed toward the diffuser 22. Part of the aerosol matrix directly absorbs the heat released by the heating element 23, atomizing into an aerosol and releasing it. Another part of the aerosol matrix flows out of the liquid guide 14 and is absorbed by the diffuser 22. This part of the aerosol matrix is ​​atomized into an aerosol under the action of the heat from the heating element 23 and released. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0376] In one embodiment, both the liquid-guiding member 14 and the diffuser 22 are made of porous materials, and the porosity of the liquid-guiding member 14 is greater than that of the diffuser 22. Since the porosity is related to the liquid absorption and permeability of the material, the greater the porosity of the material, the greater the number of closed pores, the smaller the pore diameter, the stronger the liquid absorption and permeability of the material.

[0377] Since more aerosol substrate enters the liquid-guiding member 14 than the diffuser 22, it is understandable that the liquid-guiding member 14 having a higher porosity can enable the aerosol substrate released from the liquid outlet 121 to be absorbed relatively quickly, thereby ensuring the release efficiency of the aerosol substrate by the cartridge 10 of the electronic cigarette 100 of the present application.

[0378] At the same time, since the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-guiding member 14 can also diffuse into the entire liquid-guiding member 14 more quickly, thereby achieving a match between the heat released by the heating member 23 and the diffusion member 22 and the amount of aerosol matrix guided toward the heating member 23, thereby ensuring the amount of aerosol released by the electronic cigarette 100 of the present application.

[0379] When some aerosol matrix overflows onto the surface of the diffuser 22 and is absorbed by the diffuser 22, the porosity of the diffuser 22 is smaller than that of the liquid-conducting member 14. The aerosol matrix overflowing onto the surface of the diffuser 22, while being absorbed by the absorbing diffuser, has a relatively slow penetration rate. Because the temperature decreases with increasing distance from the heating element 23, the amount of heat absorbed by the aerosol matrix also decreases. It is understandable that providing a diffuser 22 with a smaller porosity can reduce the penetration rate of the aerosol matrix, thereby extending the penetration time of the aerosol matrix, allowing the aerosol matrix to absorb more heat to atomize and form an aerosol.

[0380] That is, the matching setting of the porosity of the diffuser 22 and the liquid-conducting member 14 increases the amount of heat absorbed by the aerosol matrix from the heating element 23, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and improving the user experience of using the electronic cigarette 100 of the present application.

[0381] In one embodiment, the cigarette rod 20 further includes a push rod 24, which is fixed to the surface of the diffuser 22 and extends away from the diffuser 22. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 can pass through the guide hole 141 of the liquid guide 14 and extend into the liquid outlet 121, thereby pushing the sealing plug 131 to move along the first direction 001 away from the liquid outlet 121, thereby opening the liquid outlet 121 and enabling the cigarette rod 20 to release the aerosol matrix from the cigarette cartridge 10.

[0382] In one embodiment, as shown in Figures 27 and 28, the second housing 21 further includes a bottom cover 212, which is fixed to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. As will be appreciated, external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol released from the liquid guide 14.

[0383] In one embodiment, as shown in Figures 27 and 28, the cigarette rod 20 further includes a battery 26, which is fixed to one end of the bottom cover 212 facing the first opening 211, and the two poles of the battery 26 are electrically connected to the heating element 23 respectively to provide electrical energy to the heating element 23.

[0384] At the same time, in the first direction 001, the battery 26 is spaced apart from the bottom cover 212. In the third direction 003, the battery 26 is also spaced apart from the second housing 21. The gaps between the battery 26 and the bottom cover 212, and between the battery 26 and the second housing 21, form an air inlet passage 31. As will be appreciated, external air can be transmitted through the air inlet holes 2121 and the air inlet passage 31 to the atomization chamber 33.

[0385] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the battery 26 and the diffuser 22. The fixing plate 213 is provided with a communication hole 2131, so that the air entering through the air inlet hole 2121 can be discharged from the communication hole 2131 via the air inlet channel 31.

[0386] In one embodiment, the cigarette rod 20 further includes a positioning rod 25 , wherein one end of the positioning rod 25 is fixedly connected to the diffuser 22 , and the other end of the positioning rod 25 extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the diffuser 22 .

[0387] In one embodiment, as shown in FIG. 27 and FIG. 28 , the positioning rod 25 and the push rod 24 are an integral structure.

[0388] In one embodiment, as shown in Figures 27 and 28, the cigarette rod 20 further includes a conductive column 271 and a connecting wire 272. One end of the conductive column 271 is in contact with the heating element 23 and is conductive thereto. The other end of the conductive column 271 is fixed to and passes through the fixing plate 213, and is electrically connected to the two poles of the battery 26 through a connecting wire 272 respectively.

[0389] It can be understood that the electric energy inside the battery 26 is transmitted to the corresponding connecting wires 272 via the two poles, and then transmitted to the heating element 23 via the connecting wires 272 and the conductive column 271 in turn, thereby realizing the atomization function of the cigarette rod 20.

[0390] In one embodiment, as shown in Figures 27 and 28, the cigarette holder 20 further includes a sensor 281, and the bottom cover 212 is provided with a sensing hole 2122. The sensing hole 2122 communicates between the outside air and the air inlet passage 31. The sensor 281 is fixedly attached to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 281 is electrically connected to a terminal of the battery 26, and the other end is electrically connected to a connecting wire 272.

[0391] When external air enters the air inlet channel 31 through the air inlet hole 2121, some air also enters the air inlet channel 31 through the sensing air hole 2122. This air can trigger the sensor 281 to connect the battery 26, the terminal, and the connecting wire 272, thereby realizing the current transmission between the battery 26 and the heating element 23, and realizing the atomization function of the cigarette rod 20.

[0392] When external air does not enter the air inlet passage 31 through the sensing air holes 2122, the sensor 281 disconnects the electrical connection between the battery 26 and the connecting wire 272. It is understood that the cigarette holder 20 of the present application can utilize the user's puffing action to switch the current between the battery 26 and the heating element 23, thereby controlling the heat generated by the heating element 23, thereby improving the user experience.

[0393] In one embodiment, as shown in Figures 27 and 28, the cigarette holder 20 further includes a buffer member 282, which is placed between the battery 26 and the bottom cover 212, and the sensor 281 is fixed to the buffer member 282. The buffer member 282 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 2121.

[0394] It can be understood that the setting of the buffer member 282 not only meets the airflow transmission requirements at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 26 and the sensor 281, reducing the impact of external forces on the battery 26 and the sensor 281, and ensuring the atomization function of the cigarette rod 20 of the present application.

[0395] In one embodiment, as shown in Figures 27 and 28, the cigarette rod 20 also includes a second seal 29, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 26 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 26 and ensuring the use of the electronic cigarette 100 of the present application.

[0396] In the prior art, electronic cigarettes typically consist of a cartridge and a stem. The cartridge contains an aerosol matrix. When the cartridge and stem are connected, the battery in the stem electrically connects to the atomizer assembly inside the cartridge, which heats the aerosol matrix inside the cartridge and releases it as an aerosol.

[0397] However, in existing technologies, a single cigarette holder is typically equipped with multiple corresponding cigarette cartridges, and in existing technologies, the cigarette cartridges typically utilize an atomizer assembly to seal the aerosol matrix. Since the atomizer assembly typically has a porous structure, the aerosol matrix may leak during the transportation of the cigarette cartridge, thereby affecting the user experience.

[0398] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette cartridge with improved sealing performance, and an electronic cigarette including the electronic cigarette cartridge, which specifically includes the following technical solutions.

[0399] In a first aspect, an embodiment of the present application provides an electronic cigarette cartridge, comprising a first shell, a sealing plate, a connector, and a sealing plug. The first shell and the sealing plate enclose an oil storage bin for storing an aerosol matrix, and the sealing plugs are located in the oil storage bin.

[0400] The first shell is provided with a liquid outlet connected to the oil storage tank, the sealing plate is elastic, and the connecting piece has opposite first and second ends, the first end of the connecting piece is connected to the sealing plate, and the second end of the connecting piece is connected to the sealing plug, so that the sealing plug has a tendency to block the liquid outlet.

[0401] The cigarette cartridge of the present application is provided with a sealing plate inside the first shell so that the sealing plate and the first shell cooperate with each other to form an oil storage tank, and a liquid outlet hole is provided through the first shell, thereby ensuring that the aerosol matrix stored in the oil storage tank can flow out through the liquid outlet hole, thereby ensuring the release of the aerosol matrix by the cigarette cartridge of the present application.

[0402] The present cigarette cartridge also includes an elastic sealing plate and a connector disposed between the sealing plate and the sealing plug. The connector compresses the sealing plate, causing it to elastically deform. This allows the sealing plug to partially extend into the liquid outlet under the elastic force of the sealing plate to cover the liquid outlet, thereby sealing the oil storage tank. This improves the sealing performance of the present cigarette cartridge for aerosol matrix.

[0403] In one embodiment, the central axis of the connecting member passes through the geometric center of the sealing plate; and / or the central axis of the connecting member coincides with the central axis of the liquid outlet.

[0404] In one embodiment, the sealing plate includes a supporting portion and a connecting portion surrounding the supporting portion, the connecting portion is fixed to the first shell, and the thickness of the supporting portion of the sealing plate in a natural state is greater than the thickness of the connecting portion.

[0405] In one embodiment, a positioning hole is provided on the surface of the supporting portion facing the inner side of the oil storage tank, and the positioning hole is used to accommodate the first end of the connecting piece; or, a positioning protrusion is provided on the surface of the supporting portion facing the inner side of the oil storage tank, and the positioning protrusion surrounds the first end of the connecting piece.

[0406] In one embodiment, the elastic modulus of the sealing plate is smaller than the elastic modulus of the connecting member.

[0407] In one embodiment, the connecting member is made of a rigid material; and / or the sealing plate and the connecting member are integrally formed.

[0408] In one embodiment, the connecting piece and the sealing plug are integrally formed.

[0409] In one embodiment, the first shell is provided with a guide structure, which is located at the end of the liquid outlet facing the inner side of the oil storage tank. The guide structure is conical, and the end of the guide structure with a larger cross-sectional area is farther away from the liquid outlet than the end with a smaller cross-sectional area of ​​the guide structure.

[0410] In one embodiment, the sealing plug includes an abutment portion, which is used to contact the guide structure. The abutment portion is conical, and the end with a smaller cross-section of the abutment portion is closer to the liquid outlet than the end with a larger cross-section of the sealing plug. The abutment portion is at least partially in contact with the guide structure.

[0411] In one embodiment, the cigarette cartridge includes a liquid guiding member, which is arranged on a side of the liquid outlet away from the oil storage bin, and is used to guide the aerosol matrix to flow out of the liquid outlet.

[0412] In one embodiment, the cigarette cartridge includes a third shell, which accommodates the first shell and is spaced apart from the first shell to form an air outlet channel. The third shell includes an air outlet hole, which is located on the side of the oil storage tank away from the liquid outlet hole. The air outlet channel connects the liquid outlet hole and the air outlet hole.

[0413] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge, wherein the cigarette rod comprises a heating assembly and a push rod, wherein the push rod is used to extend into the liquid outlet to push the sealing plug, and the heating assembly is used to heat the aerosol matrix.

[0414] In one embodiment, the heating assembly includes a diffuser and a heating element, and the push rod and the heating element are both fixed to the diffuser.

[0415] In one embodiment, the diffuser is made of insulating material and has thermal conductivity. The diffuser is used to increase the heating area of ​​the heating assembly.

[0416] In one embodiment, the diffuser has a porous structure.

[0417] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette cartridge provided in the first aspect of the present application, it also has the beneficial effect of improving the sealing performance.

[0418] Please refer to FIG. 29 for a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0419] As shown in FIG29 , the electronic cigarette 100 of the present application includes a cartridge 10 and a cigarette rod 20. The cartridge 10 includes a first housing 111, and the cigarette rod 20 includes a second housing 21. An oil storage tank 14 is provided within the first housing 111, and an aerosol matrix is ​​stored within the oil storage tank 14. The cartridge 10 can partially extend into the first housing 111 through a first opening 211.

[0420] The electronic cigarette 100 of the present application also includes an air circuit 30, which connects two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposite sides of the electronic cigarette 100, allowing external air to enter from the other side of the electronic cigarette 100. The air is mixed with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and then enters the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0421] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, forming an atomization chamber 33 between the cigarette cartridge 10 and the cigarette rod 20. The air inlet channel 31 is located in the second shell 21, and the air outlet channel 32 is located in the first shell 111. The air inlet channel 31 communicates between the air inlet hole 2121 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 1121 and the atomization chamber 33.

[0422] As will be understood, when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 31 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the second housing 21 flows toward the heating element 222 of the cigarette rod 20 and absorbs the heat generated by the heating element 222, atomizing into an aerosol. The aerosol mixes with the external air and, as the user inhales, flows along the air outlet channel 32 from the air outlet 1121 into the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0423] Specifically, please refer to FIG30 for a schematic structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, FIG31 for another schematic structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG32 for an exploded schematic diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG29 for details. For ease of description, the arrangement direction of the cigarette cartridge 10 and cigarette rod 20 in FIG29 is set as a first direction 001, and the mutually perpendicular second direction 002 and third direction 003 are both perpendicular to the first direction 001.

[0424] As shown in Figures 29-32, the cigarette cartridge 10 of the present application includes a sealing plate 12 and a partition 13. The sealing plate 12 and the partition 13 are both housed within and fixed to the first housing 111. The sealing plate 12 and the partition 13 are spaced apart from each other to form an oil storage tank 14 in conjunction with the first housing 111.

[0425] The oil storage tank 14 is used to store aerosol matrix. A liquid outlet 131 is provided through the partition 13 to connect the oil storage tank 14 with the external environment, so that the aerosol matrix stored in the oil storage tank 14 can flow out through the liquid outlet 131.

[0426] The cigarette cartridge 10 of the present application also includes a connector 15 and a sealing plug 16. Both the connector 15 and the sealing plug 16 are housed within the oil storage bin 14. The connector 15 includes a first end 151 and a second end 152 disposed opposite each other. The first end is fixed to the sealing plate 12, and the second end extends toward the liquid outlet 131 and is fixedly connected to the sealing plug 16.

[0427] The sealing plate 12 is made of an elastic material. As will be appreciated, when the cigarette cartridge 10 and cigarette rod 20 are not connected, the elastic force of the sealing plate 12 is transmitted to the sealing plug 16 via the connector 15, causing the sealing plug 16 to move in the first direction 001 toward the liquid outlet 131 and block the liquid outlet 131, thereby achieving the sealing function of the cigarette cartridge 10 of the present application for the oil storage tank 14.

[0428] As shown in Figures 29-32, the combined lengths of connector 15 and sealing plug 16 are greater than the spacing between sealing plate 12 and partition 13. It will be appreciated that when one end of connector 15 and sealing plug 16 are installed, extending into oil storage bin 14 and the other end of connector 15 is secured to sealing plate 12, connector 15 causes elastic deformation of sealing plate 12, ensuring that connector 15 and sealing plug 16 are securely contained within oil storage bin 14.

[0429] When the connector 15 is connected between the sealing plug 16 and the sealing plate 12 , the elastic force inside the elastically deformed sealing plate 12 can act on the connector 15 , and the connector 15 pushes the sealing plug 16 into the liquid outlet 131 to seal the oil storage tank 14 .

[0430] It can be understood that, as shown in Figure 30, when the sealing plug 16 extends into the liquid outlet 131 and covers the liquid outlet 131, the elastic deformation of the sealing plate 12 disappears, thereby ensuring the sealing of the oil storage tank 14 by the sealing plug 16 while increasing the service life of the sealing plate 12.

[0431] On the other hand, as shown in Figure 31, when the sealing plug 16 extends into the liquid outlet 131 and covers the liquid outlet 131, the elastic deformation of the sealing plate 12 still exists, so that the sealing plate 12 can continue to apply an elastic force to the sealing plug 16 along the first direction 001 toward the liquid outlet 131, further improving the sealing effect of the cigarette cartridge 10 of the present application on the aerosol matrix.

[0432] As shown in Figure 29, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 23 of the cigarette rod 20 can extend into the liquid outlet 131 and push the sealing plug 16, and make the connecting member 15 move along the first direction 001, so that the sealing plate 12 is elastically deformed along the first direction 001, thereby releasing the aerosol matrix.

[0433] It is understood that the connector 15, made of an elastic material, can not only ensure the sealing of the oil storage tank 14, but also cooperate with the push rod 23 to release the aerosol matrix. At the same time, when the push rod 23 is withdrawn, the elastic force of the connector 15 can also enable the sealing plug 16 to continue to cover the liquid outlet 131, thereby ensuring the sealing of the oil storage tank 14.

[0434] In existing technology, the aerosol matrix is ​​typically directly released and atomized using an atomizer assembly. This is controlled by switching the atomizer assembly on and off with the battery inside the cigarette holder. However, when a cigarette cartridge is transported by a user and subjected to vibration, some of the aerosol matrix absorbed by the atomizer assembly may leak out, affecting the cartridge's sealing performance and impacting the user experience.

[0435] Therefore, compared with the prior art, the cigarette cartridge 10 of the present application is provided with a sealing plate 12 made of elastic material, and the first end 151 of the connecting member 15 is fixed to the sealing plate 12, and the second end 152 extends toward the liquid outlet 131, and a sealing plug 16 is provided, so that the elastic force stored in the sealing plate 12 due to the length of the connecting member 15 and the sealing plug 16 can drive the sealing plug 16 to cover the liquid outlet 131 to seal the oil storage tank 14. Based on the fact that the position of the connecting member 15 is relatively fixed and is difficult to change due to vibration during transportation, it can be understood that the provision of the connecting member 15 in conjunction with the elastic sealing plate 12, while ensuring that the sealing plug 16 covers the liquid outlet 131, also improves the sealing performance of the cigarette cartridge 10 of the present application on the aerosol matrix, thereby improving the user experience.

[0436] In one embodiment, as shown in Figure 32, the connecting member 15 has a first central axis L1, the sealing plate 12 has a second central axis L2, and the liquid outlet 131 has a third central axis L3. The first central axis L1, the second central axis L2, and the third central axis L3 coincide with each other.

[0437] As will be appreciated, when the first central axis L1 and the second central axis L2 coincide, the connector 15 abuts against the center of the sealing plate 12. As the connector 15 compresses the sealing plate 12 and causes elastic deformation, the force exerted by the connector 15 on the sealing plate 12 is evenly distributed around the periphery of the sealing plate 12. Furthermore, the connector 15 abutting the center of the sealing plate 12 reduces the amount of force exerted by the connector 15 on the sealing plate 12 that spreads between the sealing plate 12 and the first housing 111, thereby preventing the connector 15 from interfering with the securing of the sealing plate 12 to the first housing 111. This ensures the relative position of the sealing plate 12 and the first housing 111.

[0438] When the first central axis L1 and the third central axis L3 coincide, the sealing plug 16 extends directly into the liquid outlet 131 along the first direction 001, and the sidewalls of the sealing plug 16 simultaneously abut against the walls of the liquid outlet 131. This prevents the sealing plug 16 from squeezing the walls of the liquid outlet 131 and causing a gap between the sealing plug 16 and the liquid outlet 131. This further improves the sealing performance of the cigarette cartridge 10 of the present application for the aerosol matrix.

[0439] In one embodiment, as shown in Figures 29 and 32 , the sealing plate 12 includes a supporting portion 121 and a connecting portion 122. A sealing opening 1111 is provided on a side of the first housing 111 away from the inner side of the oil storage tank 14. The connecting portion 122 is fixed to and covers the sealing opening 1111.

[0440] The connecting portion 122 surrounds the outer periphery of the supporting portion 121 and is connected to the supporting portion 121. In the natural state of the sealing plate 12, the thickness of the supporting portion 121 is greater than the thickness of the connecting portion 122.

[0441] After the connecting member 15 is installed, the supporting portion 121 will be squeezed and deformed. Compared with the connecting portion 122 that is farther away from the connecting member 15, the deformation of the supporting portion 121 along the first direction 001 will be greater than the deformation of the connecting portion 122. It can be understood that providing a supporting portion 121 with a thickness greater than that of the connecting portion 122 can avoid the supporting portion 121 from being broken due to the abutment of the connecting member 15 when the connecting member 15 causes the supporting portion 121 to undergo elastic deformation. The sealing function of the sealing plate 12 on the aerosol matrix is ​​guaranteed, thereby ensuring the sealing performance of the cigarette cartridge 10 of the present application.

[0442] In one embodiment, as shown in Figures 30-32, a positioning hole 1211 is provided on the surface of the supporting portion 121 facing the partition 13, and the first end 151 of the connecting member 15 extends into the positioning hole 1211 and abuts against the bottom of the positioning hole 1211, so as to ensure the supporting effect of the connecting member 15 on the sealing plate 12 while preventing the connecting member 15 from being offset along the second direction 002 or the third direction 003 when the sealing plate 12 is deformed, thereby affecting the shielding function of the sealing plug 16 on the liquid outlet 131.

[0443] That is, the provision of the positioning hole 1211 and the insertion of the connector 15 into the positioning hole 1211 prevent the connector 15 from being displaced in the second direction 002 and the third direction 003 when the sealing plate 12 undergoes elastic deformation, thereby ensuring that the elastic force of the sealing plate 12 acts on the sealing plug 16. This further improves the sealing performance of the cigarette cartridge 10 of the present application for the aerosol matrix.

[0444] Please refer to FIG. 33 for another structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application.

[0445] As shown in FIG33 , a positioning protrusion 1212 is provided on the surface of the abutting portion 121 facing the partition 13. The positioning protrusion 1212 surrounds the first end 151 of the connecting member 15, preventing the connecting member 15 from shifting along the second direction 002 and the third direction 003 when the sealing plate 12 undergoes elastic deformation, thereby ensuring that the elastic force of the sealing plate 12 acts on the sealing plug 16. This further improves the sealing performance of the cigarette cartridge 10 of the present application for the aerosol matrix.

[0446] In one embodiment, the elastic modulus of the sealing plate 12 is smaller than the elastic modulus of the connector 15. The larger the elastic modulus of the material, the more difficult it is for the corresponding material to deform. When the cigarette cartridge 10 and the cigarette rod 20 are connected, the push rod 23 needs to be extended into the liquid outlet 131 and push the connector 15. It can be understood that setting the sealing plate 12 with an elastic modulus smaller than the elastic modulus of the connector 15 can reduce the force used by the push rod 23 to push the connector 15 when the push rod 23 pushes the connector 15 and causes the sealing plate 12 to deform, thereby improving the user experience.

[0447] In one embodiment, the connector 15 is made of a rigid material, and the sealing plate 12, the connector 15, and the sealing plug 16 are integrally formed. It is understood that in another embodiment, the connector 15 and the sealing plug 16 are an integral structure. In another embodiment, the sealing plate 12 and the connector 15 are integrally formed.

[0448] In one embodiment, as shown in Figures 29 to 32, a guide structure 131a is further provided on the first shell 111. The guide structure 131a is located on the end of the liquid outlet 131 facing the inner side of the oil storage tank 14. The guide structure 131a is conical and includes a first guide port 1311 and a second guide port 1312 that are arranged opposite to each other. The first guide port 1311 is connected to the liquid outlet 131, and the aperture of the first guide port 1311 is smaller than the aperture of the second guide port 1312. That is, the end of the guide structure 131a with a larger cross-section is away from the liquid outlet 131, and the end with a smaller cross-section is closer to the liquid outlet 131.

[0449] When the cigarette cartridge 10 and cigarette rod 20 are disconnected, the sealing plug 16 can move toward the liquid outlet 131 extending into the guide structure 131a under the elastic force of the sealing plate 12. It can be understood that the tapered guide structure 131a can guide the sealing plug 16 toward the liquid outlet 131, and the side wall of the sealing plug 16 abuts against the tapered inner wall of the guide structure 131a, thereby sealing the oil storage tank 14.

[0450] In one embodiment, as shown in Figures 29 to 32 , the sealing plug 16 includes an abutment portion 161, which is located on the side of the sealing plug 16 facing the liquid outlet 131. The abutment portion 161 is tapered, and the end of the tapered abutment portion 161 with a smaller cross-sectional area is closer to the liquid outlet 131.

[0451] When the cigarette cartridge 10 is not connected to the cigarette rod 20, the elastic force of the sealing plate 12 of the cigarette cartridge 10 pushes the sealing plug 16 toward the liquid outlet 131, causing the abutment portion 161 to partially extend into the guide structure 131a. The tapered outer wall of the abutment portion 161 extending into the guide structure 131a abuts the tapered inner wall of the guide structure 131a, thereby sealing the oil storage tank 14 with the sealing plug 16. This further improves the sealing performance of the cigarette cartridge 10 for the aerosol matrix.

[0452] It is understood that in another embodiment, the guide structure 131a is a circular hole, and the abutting portion 161 of the sealing plug 16 is conical. The abutting portion 161 can at least partially extend into the guide structure 131a under the elastic force of the sealing plate 12 to seal the oil storage tank 14. In another embodiment, the guide structure 131a is conical, and the abutting portion 161 of the sealing plug 16 is cylindrical. When the abutting portion 161 extends into the guide structure 131a under the elastic force of the sealing plate 12, the conical inner wall of the guide structure 131a can guide the sealing plug 16 to extend into the guide structure 131a to seal the oil storage tank 14. In other embodiments, the shapes of the sealing plug 16 and the liquid outlet 131 can also be other, and this application does not specifically limit this.

[0453] In one embodiment, the sealing plug 16 can be made of elastic material, and the conical inclination angle of the guide structure 131 a is smaller than the conical inclination angle of the abutment portion 161 . The abutment portion 161 generates elastic deformation in the guide structure 131 a to seal the oil storage tank 14 .

[0454] In one embodiment, as shown in Figures 30 and 31, the cigarette cartridge 10 also includes a liquid guide 17, which is fixed to the outer surface of the partition 13 away from the oil storage tank 14, and a guide hole 171 is provided through the liquid guide 17 so that the push rod 23 of the cigarette rod 20 can enter the liquid outlet 131 through the guide hole 171.

[0455] As shown in Figures 29 and 30, when the cartridge 10 and the cigarette rod 20 are assembled, the push rod 23 releases the aerosol matrix in the oil reservoir 14. The aerosol matrix can flow from the liquid outlet 131 to the liquid guide 17 and be absorbed by the liquid guide 17. The liquid guide 17 can guide the aerosol matrix toward the heating assembly 22 of the cigarette rod 20 and, in conjunction with the heat released by the heating assembly 22, atomize the aerosol matrix to form an aerosol. This achieves the aerosol matrix atomization function of the electronic cigarette 100 of the present application.

[0456] In one embodiment, as shown in Figures 30 and 31 , the cigarette cartridge 10 includes a third housing 112. The first housing 111 is housed within the third housing 112. The first housing 111 also includes an air outlet 1121, located on the side of the oil storage tank 14 facing away from the liquid outlet 131. The first and third housings 111, 112 are spaced apart to form an air outlet channel 32. The air outlet channel 32 is also connected to the air outlet 1121.

[0457] It is understood that after the aerosol matrix flowing out of the liquid outlet 131 is heated and atomized by the heating assembly 22 of the cigarette rod 20, the formed aerosol can flow from the atomization chamber 33 to the air outlet 1121 through the air outlet channel 32 and be output outward from the air outlet 1121. This realizes the user's inhalation function of the electronic cigarette 100 of the present application.

[0458] Please refer to FIG34 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG35 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG29 .

[0459] As shown in Figures 29, 34, and 35, the cigarette cartridge 10 of the present application further includes a support member 181. The first shell 111 is cylindrical, and a plurality of support members 181 are provided. The plurality of support members 181 are spaced apart along the circumference of the first shell 111, and each support member 181 is fixed between the first shell 111 and the third shell 112.

[0460] A gap is left between each two adjacent support members 181 to form an air outlet channel 32. It can be understood that the mixed gas of aerosol and air entering from the first opening 211 can be transmitted from between the two adjacent support members 181 to the air outlet hole 1121.

[0461] In one embodiment, as shown in Figures 34 and 35, the cigarette cartridge 10 further includes a liquid wick 182, which is disposed between each two adjacent support members 181 and spaced apart from at least one support member 181 to ensure that the mixed gas of aerosol and air entering through the first opening 211 can be discharged. The liquid wick 182 can be used to absorb the aerosol matrix condensed during the transmission process, preventing the aerosol matrix from entering the mouth through the air outlet channel 32, thereby ensuring a good user experience.

[0462] In one embodiment, as shown in Figures 29 to 33, the cigarette cartridge 10 further includes a seal 19, which surrounds the periphery of the partition 13 and extends toward the liquid guide 17. The seal 19 cooperates with the partition 13 and the liquid guide 17 to form a relatively sealed space between the liquid guide 17 and the partition 13. When the aerosol matrix flows out from the liquid outlet 131, it may flow to the side wall of the seal 19 due to the influence of the posture of the cigarette cartridge 10. It can be understood that the setting of the seal 19 allows this part of the aerosol matrix to flow toward the liquid guide 17 under the guidance of the seal 19, thereby preventing the leakage of the aerosol matrix. This further improves the sealing performance of the cigarette cartridge 10 of the present application.

[0463] Please refer to FIG36 for a schematic structural diagram of a cigarette rod 20 provided in one embodiment of the present application, and FIG37 for a schematic cross-sectional structural diagram of a cigarette rod 20 provided in one embodiment of the present application.

[0464] As shown in Figures 29, 36, and 37, the cigarette holder 20 of the present application further includes a heating assembly 22. The heating assembly 22 comprises a diffuser 221 and a heater 222. The diffuser 221 is made of a porous material. When the cigarette cartridge 10 and cigarette holder 20 are assembled as one, the diffuser 221 absorbs aerosol substrate flowing from the first opening 211 into the second housing 21, preventing the inflowing aerosol substrate from flowing into the air path 30, thereby ensuring a superior user experience.

[0465] The heating element 222 is fixed to the diffuser 221 to heat the diffuser 221 and atomize the aerosol matrix absorbed by the diffuser 221 into aerosol and release it into the atomization chamber 33, thereby preventing the aerosol matrix stored in the diffuser 221 from flowing out of the diffuser 221.

[0466] At the same time, since the diffuser 221 is made of insulating material and has thermal conductivity, it is understandable that the heat of the heater 222 can also be transferred to the liquid guide 17 to atomize the aerosol matrix in the liquid guide 17. This realizes the atomization function of the aerosol matrix of the cigarette holder 20 of the present application. On the other hand, based on the cross-sectional area of ​​the heater 222 being smaller than the cross-sectional area of ​​the diffuser 221, it is understandable that the diffuser 221 with thermal conductivity can also diffuse the heat of the heater 222, thereby increasing the aerosol matrix's absorption rate of the heat of the heater 222, thereby improving the atomization efficiency of the aerosol matrix of the cigarette holder 20 of the present application.

[0467] In one embodiment, as shown in Figures 29, 36, and 37, the heating element 222 is fixed to the surface of the diffuser 221 away from the first opening 211. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the surface of the diffuser 221 facing the first opening 211 is in contact with the surface of the liquid guide 17.

[0468] As can be understood, the aerosol matrix within the oil storage tank 14 is absorbed by the liquid guide member 17 through the liquid outlet 131 and directed toward the diffuser 221. Part of the aerosol matrix is ​​atomized into aerosol and released due to the heat released by the diffuser 221 after being heated by the heater 222. Another part of the aerosol matrix flows out of the liquid guide member 17 and is absorbed by the diffuser 221. This part of the aerosol matrix is ​​atomized into aerosol and released due to the heat from the heater 222. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0469] In another embodiment, the heating element 222 is fixed to the surface of the diffuser 221 facing the first opening 211 , and the diffuser 221 has a surface partially exposed from the heating element 222 , so that the aerosol matrix flowing out of the liquid guide 17 can contact the diffuser 221 and be absorbed by the diffuser 221 .

[0470] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the surface of the heating element 222 facing the first opening 211 is in contact with the surface of the liquid guide 17. The aerosol matrix in the oil storage tank 14 is absorbed by the liquid guide 17 through the liquid outlet 131 and directed toward the diffuser 221. Part of the aerosol matrix directly absorbs the heat released by the heating element 222, atomizing into aerosol and releasing it. Another part of the aerosol matrix flows out of the liquid guide 17 and is absorbed by the diffuser 221. This part of the aerosol matrix is ​​atomized into aerosol under the action of the heat from the heating element 222 and released. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0471] In one embodiment, both the liquid-guiding member 17 and the diffuser 221 are made of porous materials, and the porosity of the liquid-guiding member 17 is greater than that of the diffuser 221. Since the porosity is related to the liquid absorption and permeability of the material, the greater the porosity of the material, the greater the number of closed pores, the smaller the pore diameter, the greater the liquid absorption and permeability of the material.

[0472] Since more aerosol substrate enters the liquid guide 17 than the diffuser 221, it is understandable that the liquid guide 17 with a higher porosity can enable the aerosol substrate released from the liquid outlet 131 to be absorbed relatively quickly, thereby ensuring the release efficiency of the aerosol substrate by the cartridge 10 of the electronic cigarette 100 of the present application.

[0473] At the same time, since the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-guiding member 17 can also diffuse into the entire liquid-guiding member 17 more quickly, thereby achieving a match between the heat released by the heating member 222 and the diffuser 221 and the amount of aerosol matrix guided toward the heating member 222, thereby ensuring the amount of aerosol released by the electronic cigarette 100 of the present application.

[0474] When some aerosol matrix overflows onto the surface of the diffuser 221 and is absorbed by the diffuser 221, the porosity of the diffuser 221 is smaller than that of the liquid-conducting member 17. The aerosol matrix overflowing onto the surface of the diffuser 221, while being absorbed by the main absorbing member, has a relatively slow penetration rate. Because the temperature decreases with increasing distance from the heating member 222, the amount of heat absorbed by the aerosol matrix also decreases accordingly. It is understandable that providing a diffuser 221 with a smaller porosity can reduce the penetration rate of the aerosol matrix, thereby extending the penetration time of the aerosol matrix, allowing the aerosol matrix to absorb more heat to atomize and form an aerosol.

[0475] That is, the matching setting of the porosity of the diffuser 221 and the liquid guide 17 increases the amount of heat absorbed by the aerosol matrix from the heating element 222, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and improving the user experience of using the electronic cigarette 100 of the present application.

[0476] In one embodiment, the cigarette rod 20 further includes a push rod 23, which is fixed to the surface of the diffuser 221 and extends away from the diffuser 221. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 23 can pass through the guide hole 171 of the liquid guide 17 and extend into the liquid outlet 131, thereby pushing the sealing plug 16 to move along the first direction 001 away from the liquid outlet 131, thereby opening the liquid outlet 131 and enabling the cigarette rod 20 to release the aerosol matrix from the cigarette cartridge 10.

[0477] In one embodiment, as shown in Figures 36 and 37 , the second housing 21 further includes a bottom cover 212, which is fixed to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. As will be appreciated, external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol released from the liquid guide 17.

[0478] In one embodiment, as shown in Figures 35 and 36, the cigarette rod 20 further includes a battery 25, which is fixed to one end of the bottom cover 212 facing the first opening 211, and the two poles of the battery 25 are respectively electrically connected to the heating element 222 to provide electrical energy to the heating element 222.

[0479] At the same time, in the first direction 001, the battery 25 is spaced apart from the bottom cover 212. In the third direction 003, the battery 25 is also spaced apart from the second housing 21. The gaps between the battery 25 and the bottom cover 212, and between the battery 25 and the second housing 21, cooperate to form an air inlet passage 31. As will be appreciated, external air can be transmitted through the air inlet holes 2121 and the air inlet passage 31 to the atomization chamber 33.

[0480] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the battery 25 and the diffuser 221. The fixing plate 213 is provided with a communication hole 2131, so that the air entering through the air inlet hole 2121 can be discharged from the communication hole 2131 via the air inlet channel 31.

[0481] In one embodiment, the cigarette rod 20 further includes a positioning rod 24 , wherein one end of the positioning rod 24 is fixedly connected to the diffuser 221 , and the other end of the positioning rod 24 extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the diffuser 221 .

[0482] In one embodiment, as shown in FIG. 36 and FIG. 37 , the positioning rod 24 and the push rod 23 are an integral structure.

[0483] In one embodiment, as shown in Figures 36 and 37, the cigarette rod 20 further includes a conductive column 261 and a connecting wire 262. One end of the conductive column 261 is in contact with the heating element 222 for conduction, and the other end of the conductive column 261 is fixed to and passes through the fixing plate 213, and is electrically connected to the two poles of the battery 25 through a connecting wire 262 respectively.

[0484] It can be understood that the electric energy inside the battery 25 is transmitted to the corresponding connecting wires 262 via the two poles, and then transmitted to the heating element 222 via the connecting wires 262 and the conductive column 261 in turn, thereby realizing the atomization function of the cigarette rod 20.

[0485] In one embodiment, as shown in Figures 36 and 37 , the cigarette holder 20 further includes a sensor 271, and a sensing hole 2122 is provided on the bottom cover 212. The sensing hole 2122 communicates between the outside air and the air inlet passage 31. The sensor 271 is fixedly attached to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 271 is electrically connected to a terminal of the battery 25, and the other end is electrically connected to a connecting wire 262.

[0486] When external air enters the air inlet channel 31 through the air inlet hole 2121, some air also enters the air inlet channel 31 through the sensing air hole 2122. This air can trigger the sensor 271 to connect the battery 25, the terminal, and the connecting wire 262, thereby realizing the current transmission between the battery 25 and the heating element 222, and realizing the atomization function of the cigarette rod 20.

[0487] When external air does not enter the air inlet passage 31 through the sensing air holes 2122, the sensor 271 disconnects the electrical connection between the battery 25 and the connecting wire 262. It is understood that the cigarette holder 20 of the present application can utilize the user's puffing action to switch the current between the battery 25 and the heating element 222, thereby controlling the heat generated by the heating element 222, thereby improving the user experience.

[0488] In one embodiment, as shown in Figures 36 and 37, the cigarette holder 20 further includes a buffer member 272, which is placed between the battery 25 and the bottom cover 212, and the sensor 271 is fixed to the buffer member 272. The buffer member 272 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 2121.

[0489] It can be understood that the setting of the buffer member 272 not only meets the airflow transmission requirements at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 25 and the sensor 271, reducing the impact of external forces on the battery 25 and the sensor 271, and ensuring the atomization function of the cigarette rod 20 of the present application.

[0490] In one embodiment, as shown in Figures 36 and 37, the cigarette rod 20 also includes a second seal 28, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 25 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 25 and ensuring the use of the electronic cigarette 100 of the present application.

[0491] In the prior art, e-cigarettes typically consist of a cartridge and a stem. The cartridge's reservoir contains an aerosol matrix. When the cartridge and stem are connected, the battery in the stem electrically connects to a heating element within the cartridge, which heats the aerosol matrix and releases it as an aerosol.

[0492] However, in the prior art, the airway connecting the atomization chamber and the air outlet of the electronic cigarette is usually set in the oil storage tank. During the manufacturing process, the pipeline forming the airway usually needs to be designed and manufactured separately, which makes the manufacturing process of the cigarette cartridge relatively complicated.

[0493] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette cartridge that is easy to manufacture, and an electronic cigarette including the electronic cigarette cartridge, which specifically includes the following technical solutions.

[0494] In a first aspect, an embodiment of the present application provides an electronic cigarette cartridge, comprising a first shell and a third shell, wherein the first shell is provided with an oil storage tank for storing an aerosol matrix;

[0495] The third shell accommodates the first shell. The first shell and the third shell are spaced apart from each other to form an air outlet channel. The third shell is further provided with an air outlet hole. The air outlet channel is communicated with the air outlet hole.

[0496] The cigarette cartridge of the present application has an air outlet hole provided on the third shell, and an air outlet channel provided between the first shell and the third shell, so that the aerosol formed by the vaporization of the electronic cigarette mixes with the external air and then flows out to the air outlet hole through the air outlet channel. This simplifies the manufacturing process of the cigarette cartridge of the present application while ensuring the aerosol and air transport function of the cigarette cartridge of the present application, making it easier to manufacture the cigarette cartridge of the present application.

[0497] In one embodiment, the first shell is provided with a liquid outlet hole, and the liquid outlet hole is used to release the aerosol matrix.

[0498] In one embodiment, an atomization chamber is provided between the first shell and the third shell, and the air outlet channel and the air outlet hole are respectively connected to the atomization chamber. In one embodiment, the cigarette cartridge includes a support member, the support member is located between the first shell and the third shell, and the support member is used to define the spacing distance between the first shell and the third shell.

[0499] In one embodiment, there are multiple support members, which are spaced apart along the outer contour of the cigarette cartridge in a direction perpendicular to the assembly direction of the cigarette cartridge and the cigarette rod, and the air outlet channel is located between each two adjacent support members.

[0500] In one embodiment, the cigarette cartridge includes at least one liquid absorbent component, the liquid absorbent component contains pores, and the liquid absorbent component is arranged in the air outlet channel.

[0501] In one embodiment, the liquid-absorbing member is spaced apart from the first shell or the third shell.

[0502] In one embodiment, the liquid-absorbing member is spaced apart from at least one adjacent supporting member.

[0503] In one embodiment, there are multiple absorbent members, and at most one absorbent member is filled between any two adjacent support members.

[0504] In one embodiment, the absorbent member is made of a porous material.

[0505] In one embodiment, the absorbent member is made of cotton, sponge or ceramic.

[0506] In one embodiment, the support member is made of metal or plastic.

[0507] In one embodiment, the support member and the third shell are integrally formed.

[0508] In one embodiment, the outer wall of the first shell and / or the inner wall of the third shell are cylindrical.

[0509] In one embodiment, the support member extends in a spiral shape along the direction in which the cigarette rod and the cigarette cartridge are assembled.

[0510] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge. An air inlet is provided on a side of the cigarette rod away from the cigarette cartridge, and the air inlet is connected to the air outlet through an air outlet channel.

[0511] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette cartridge provided in the first aspect of the present application, it also has the beneficial effect of being easy to manufacture.

[0512] Please refer to FIG. 38 for a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0513] As shown in FIG38 , the electronic cigarette 100 of the present application includes a cartridge 10 and a cigarette rod 20. The cartridge 10 includes a first housing 111, and the cigarette rod 20 includes a second housing 21. The first housing 111 includes an oil storage tank 12, which stores an aerosol matrix. The second housing 21 has a first opening 211, through which the cartridge 10 can partially extend into the first housing 111.

[0514] Specifically, the electronic cigarette 100 of the present application further includes an air circuit 30, which connects two opposing sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposing sides of the electronic cigarette 100. This allows external air to enter from the other side of the electronic cigarette 100 and mix with the aerosol released from the atomized aerosol matrix within the electronic cigarette 100 before entering the user's mouth, thereby achieving the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0515] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, forming an atomization chamber 33 between the cigarette cartridge 10 and the cigarette rod 20. The air inlet channel 31 is located in the second shell 21, and the air outlet channel 32 is located in the first shell 111. The air inlet channel 31 communicates between the air inlet hole 2121 of the cigarette rod 20 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 1121 of the cigarette cartridge 10 and the atomization chamber 33.

[0516] As will be understood, when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 31 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the second housing 21 flows toward the heating element 23 of the cigarette rod 20, absorbing the heat generated by the heating element 23 and atomizing into an aerosol. The aerosol mixes with the external air and, as the user inhales, flows along the air outlet channel 32 from the air outlet 1121 into the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0517] For details, please refer to FIG39 , which shows a schematic diagram of the structure of the cigarette cartridge 10 provided in one embodiment of the present application, and FIG40 , which shows an exploded schematic diagram of the cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG38 . For ease of description, the arrangement direction of the cigarette cartridge 10 and cigarette rod 20 in FIG38 is set as a first direction 001 , and the second direction 002 is perpendicular to the first direction 001 .

[0518] As shown in Figures 38-40, the cigarette cartridge 10 of the present application further includes an oil storage tank 12, which is housed within the first housing 111 and is used to store aerosol substrate. The oil storage tank 12 is provided with a liquid outlet 121, which connects the oil storage tank 12 with the external environment, allowing the aerosol substrate stored in the oil storage tank 12 to flow out of the oil storage tank 12 through the liquid outlet 121.

[0519] As shown in Figures 38-40, along the second direction 002, the first shell 111 and the third shell 112 are spaced apart from each other to form an air outlet channel 32. An air outlet hole 1121 is further provided on a side of the third shell 112 away from the liquid outlet 121, and the air outlet hole 1121 is connected to the air outlet channel 32.

[0520] When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix in the cigarette cartridge 10 can be atomized into aerosol under the action of the heating element 23 of the cigarette rod 20 and enter the atomization chamber 33. At the same time, external air can also enter the atomization chamber 33 through the air inlet 2121 and mix with the aerosol.

[0521] It can be understood that after the aerosol and external air are mixed in the atomization chamber 33, they can be transmitted along the air outlet channel 32 to the air outlet hole 1121 and enter the user's mouth through the air outlet hole 1121, thereby realizing the use function of the electronic cigarette 100 of the present application.

[0522] In the prior art, the air path in the e-cigarette cartridge is usually set in the liquid storage chamber of the oil storage tank. On the one hand, it occupies the space of the liquid storage chamber and reduces the storage capacity of the aerosol matrix. On the other hand, in the process of manufacturing the cartridge, it is necessary to set up the pipeline forming the air path, which increases the complexity of the design and manufacturing of the cartridge and is not conducive to the manufacturing of the cartridge.

[0523] Therefore, compared with the prior art, the cigarette cartridge 10 of the present application provides an air outlet channel 32 between the first shell 111 and the third shell 112, and provides an air outlet hole 1121 on the third shell 112, and the air outlet hole 1121 is connected to the air outlet channel 32. Thus, while ensuring the aerosol and air transport function of the cigarette cartridge 10 of the present application, the manufacturing process of the cigarette cartridge 10 of the present application is simplified, and the manufacturing of the cigarette cartridge 10 of the present application is facilitated.

[0524] Furthermore, positioning the outlet channel 32 outside the first housing 111 prevents the structure forming the outlet channel 32 from affecting the amount of aerosol matrix stored. Furthermore, since the aerosol matrix stored within the first housing 111 is liquid, in the prior art, when the outlet channel 32 is located within the oil storage tank 12, the aerosol matrix absorbs heat from the aerosol, increasing the likelihood of aerosol condensation.

[0525] That is, arranging the air outlet channel 32 on the periphery of the oil storage tank 12 can also reduce the absorption of heat of the aerosol by the aerosol matrix, thereby ensuring the content of the aerosol released from the cigarette cartridge 10 through the air outlet 1121. Further, the user experience is improved.

[0526] In one embodiment, as shown in Figures 38-40 , a second opening 1122 is further defined on a side of the third housing 112 away from the air outlet 1121. As shown in Figure 39 , along the first direction 001, a cavity remains between the first housing 111 and the third housing 112. This cavity communicates with the external environment through the second opening 1122.

[0527] When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the cigarette cartridge 10 extends into the second shell 21 through the first opening 211. Correspondingly, the second opening 1122 also extends into the second shell 21 along with the cigarette cartridge 10. It can be understood that the cavity between the first shell 111 and the third shell 112 cooperates with the second shell 21 to form the atomization chamber 33. That is, along the first direction 001, the atomization chamber 33 is defined between the first shell 111 and the third shell 112.

[0528] The air outlet channel 32 is connected between the air outlet hole 1121 and the atomization chamber 33. It can be understood that the aerosol matrix released by the cigarette cartridge 10 can be atomized into an aerosol under the action of the heating element 23 of the cigarette rod 20, and after mixing with the external air entering from the second opening 1122, it flows out through the air outlet channel 32 and the air outlet hole 1121 in sequence.

[0529] Please refer to FIG41 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG42 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG39 .

[0530] As shown in Figures 39, 41, and 42, the cigarette cartridge 10 of the present application further includes a support member 13. The support member 13 is located between the first shell 111 and the third shell 112, so that the first shell 111 and the third shell 112 are spaced apart from each other along the second direction 002, thereby forming an air outlet channel 32 of the cigarette cartridge 10 of the present application. This ensures communication between the second opening 1122 and the air outlet hole 1121 of the cigarette cartridge 10 of the present application.

[0531] At the same time, the support member 13 can also support the first housing 111. As shown in Figure 39, the first housing 111 is accommodated in the third housing 112. The support member 13 can ensure a gap between the first housing 111 and the third housing 112 while also supporting the first housing 111 to achieve a fixed relative position between the first housing 111 and the third housing 112.

[0532] In one embodiment, as shown in Figures 39, 41, and 42, the outer wall of the first housing 111 is cylindrical, and there are multiple support members 13. The multiple support members 13 are circumferentially spaced apart along the circumference of the first housing 111, so that two adjacent support members 13 can cooperate with the first housing 111 and the third housing 112 to form an air outlet channel 32. The arrangement of the multiple support members 13 forms multiple air outlet channels 32 between the first housing 111 and the third housing 112.

[0533] It can be understood that in other embodiments, the outer wall shape of the first shell 111 can also be other. Correspondingly, the support member 13 can be arranged between the first shell 111 and the third shell 112 along the outer contour of the cigarette cartridge 10, perpendicular to the assembly direction of the cigarette cartridge 10 and the cigarette rod 20.

[0534] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the aerosol in the atomization chamber 33, after mixing with the external air, can be dispersed through the multiple air outlet channels 32. It can be understood that the provision of multiple support members 13 blocks the transmission path of the aerosol and air, thereby increasing the mixing time of the aerosol and air, and improving the mixing efficiency of the aerosol and air, thereby improving the user's taste.

[0535] In one embodiment, as shown in FIG41 , a plurality of support members 13 are evenly distributed circumferentially to improve the consistency of the mixing ratio of the aerosol and air mixed gas flowing out of each air outlet channel 32 , thereby further improving the user's taste.

[0536] 41 and 42 , the support member 13 is fixed to the inner wall of the third housing 112. It is understood that in another embodiment, as shown in FIG43 , the support member 13 may also be fixed to the outer wall of the first housing 111.

[0537] In one embodiment, as shown in Figures 41-43, the cigarette cartridge 10 of the present application further includes a liquid absorbent member 14. The liquid absorbent member 14 is made of a porous material and is filled between two adjacent support members 13. During the aerosol's transportation, the heat of the aerosol may be absorbed by the aerosol matrix in the oil storage tank 12 and the external air. It is understood that the provision of the liquid absorbent member 14 allows the aerosol that condenses into the aerosol matrix due to heat reduction to be absorbed, thereby preventing the condensed aerosol matrix from being inhaled by the user, thereby improving the user experience.

[0538] In one embodiment, as shown in Figures 41 and 42 , the thickness of the liquid wicking member 14 along the radial direction of the first shell 111 is less than the distance between the outer wall of the first shell 111 and the inner wall of the third shell 112. As shown in Figure 41 , the liquid wicking member 14 is in contact with the inner wall of the third shell 112. That is, the liquid wicking member 14 is spaced apart from the first shell 111 to form an air outlet channel 32. As will be appreciated, aerosol and air can flow through the gap between the liquid wicking member 14 and the first shell 111 toward the air outlet 1121, thereby enabling the inhalation function of the electronic cigarette 100.

[0539] In another embodiment, the absorbent member 14 can also be attached to the outer wall of the first shell 111. Accordingly, the absorbent member 14 is spaced apart from the third shell 112 to form an air outlet channel 32. In another embodiment, the absorbent member 14 can also be spaced apart from both the first shell 111 and the third shell 112 along the radial direction of the first shell 111. Accordingly, the gaps between the absorbent member 14 and both the first shell 111 and the third shell 112 can form an air outlet channel 32. This application does not specifically limit this.

[0540] Please refer to FIG. 44 for another partial structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application, and FIG. 45 for another cross-sectional structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG. 39 .

[0541] As shown in Figures 39, 44, and 45, along the circumference of the first shell 111, the wicking member 14 is spaced apart from an adjacent support member 13. The wicking member 14 is fixed to the outer wall of the first shell 111 and the inner wall of the third shell 112. Along the circumference of the first shell 111, the wicking member 14 is in contact with one support member 13. That is, the wicking member 14 is spaced apart from the other support member 13 to form an air outlet channel 32. As will be appreciated, aerosol and air can flow through the gap between the wicking member 14 and the other support member 13 toward the air outlet 1121, thereby achieving the inhalation function of the electronic cigarette 100.

[0542] It is understandable that in another embodiment, the liquid absorbing member 14 can also be spaced apart from two supporting members 13. That is, two air outlet channels 32 are formed between two adjacent supporting members 13. This application does not impose any particular limitation on this.

[0543] In one embodiment, as shown in Figures 38 and 39, the liquid absorbing member 14 includes an extension section 141 that extends toward the second opening 1122 and into the atomization chamber 33. It is understood that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix released by the heating element 23 on the cigarette rod 20 and the cigarette cartridge 10, combined with the aerosol matrix formed by atomization, is transported toward the air outlet channel 32. The liquid absorbing member 14 can also absorb the aerosol condensed in the atomization chamber 33, further enhancing the user experience.

[0544] In one embodiment, referring back to Figures 41, 43, and 44, there are multiple wicking members 14, and the number of wicking members 14 is the same as the number of support members 13. A wicking member 14 is placed between each pair of adjacent support members 13. This ensures that when the aerosol is transmitted through each outlet channel 32 toward the outlet hole 1121, the condensed aerosol matrix is ​​absorbed by the wicking member 14, further enhancing the user experience.

[0545] It is understandable that in other embodiments, as shown in Figure 46, the number of liquid absorbent members 14 may be less than the number of support members 13. Accordingly, one liquid absorbent member 14 may be filled between two adjacent support members 13. This application does not impose any particular limitation on this.

[0546] In one embodiment, the absorbent member 14 is made of cotton, sponge or ceramic.

[0547] In one embodiment, the support member 13 is made of metal or plastic.

[0548] In one embodiment, the support member 13 may further extend in a spiral shape along the first direction 001. It is understood that providing the support member 13 extending in a spiral shape increases the overall length of the support member 13, thereby increasing the length of the air outlet channel 32, and increasing the mixing time of the aerosol and air entering the air outlet channel 32 from the atomization chamber 33, further improving the mixing quality of the aerosol and air, and further enhancing the user's taste.

[0549] In one embodiment, as shown in Figures 38 and 39, the cigarette cartridge 10 further includes a partition 122, which is fixed within the first housing 111 and cooperates with the first housing 111 to form the oil storage bin 12. A liquid outlet 121 is provided on the partition 122. As will be appreciated, the aerosol substrate stored in the oil storage bin 12 can flow out through the partition 122 via the liquid outlet 121.

[0550] As shown in Figures 38 and 39, a sealing opening 1111 is provided on one side of the first shell 111 away from the liquid outlet 121. The cartridge 10 further includes a sealing plate 153, which is fixed to and covers the sealing opening 1111. The partition plate 122 and the first shell 111 cooperate to form the oil storage tank 12.

[0551] In one embodiment, as shown in Figures 38 and 39, the cigarette cartridge 10 of the present application further includes a sealing plug 151 and a connecting member 152. The sealing plug 151 and the connecting member 152 are both housed in the oil storage bin 12, with one end of the connecting member 152 fixed to the sealing plate 153 and the other end extending toward the liquid outlet 121 and fixedly connected to the sealing plug 151.

[0552] In one embodiment, as shown in Figures 38 and 39, the cigarette cartridge 10 further includes a seal 16, which surrounds the periphery of the partition 122 and extends away from the partition 122. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one body, as shown in Figure 38, the seal 16 is also located between the diffuser 22 of the cigarette rod 20 and the first shell 111. It is understood that the seal 16 also cooperates with the partition 122 and the cigarette rod 20 to form a relatively sealed space between the diffuser 22 of the cigarette rod 20 and the partition 122. When the aerosol matrix flows out of the liquid outlet 121, it may flow onto the sidewall of the seal 16 due to the influence of the posture of the cigarette cartridge 10. It is understood that the provision of the seal 16 allows this portion of the aerosol matrix to flow toward the cigarette rod 20 under the guidance of the seal 16, thereby preventing the aerosol matrix from leaking. This improves the sealing performance of the cigarette cartridge 10 of the present application.

[0553] Please refer to Figure 47, a schematic diagram of the structure of a cigarette rod 20 provided in one embodiment of the present application, and Figure 48, a schematic diagram of the cross-sectional structure of a cigarette rod 20 provided in one embodiment of the present application. Please also refer to Figure 38. Figures 47 and 48 are schematic diagrams of the structure of the cigarette rod 20 from different directions. To facilitate the relationship between Figures 47 and 48, a third direction 003 is provided that is perpendicular to both the first direction 001 and the second direction 002.

[0554] As shown in Figures 38, 47, and 48, the cigarette holder 20 of the present application further includes a diffuser 22 and a heater 23. The diffuser 22 is made of a porous material. When the cigarette cartridge 10 and cigarette holder 20 are assembled, the diffuser 22 absorbs aerosol substrate flowing into the second housing 21 from the first opening 211, preventing the inflowing aerosol substrate from flowing into the air path 30, thereby ensuring a good user experience.

[0555] The heater 23 is fixed to the diffuser 22 to heat the diffuser 22 and atomize the aerosol matrix absorbed by the diffuser 22 into an aerosol, which is then released into the atomization chamber 33. This prevents the aerosol matrix stored in the diffuser 22 from flowing out of the diffuser 22. Simultaneously, the heat from the heater 23 can also atomize the aerosol matrix, thereby achieving the aerosol matrix atomization function of the cigarette holder 20 of the present application.

[0556] In one embodiment, as shown in Figures 38, 47 and 48, the heating element 23 is fixed to the surface of the diffuser 22 away from the first opening 211. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the surface of the diffuser 22 facing the first opening 211 is close to the cigarette cartridge 10.

[0557] As will be appreciated, the aerosol matrix within the oil storage tank 12 can be directed to the diffuser 22 via the liquid outlet 121. Part of the aerosol matrix is ​​atomized into aerosol and released due to the heat released by the diffuser 22 after being heated by the heater 23, while another part of the aerosol matrix is ​​absorbed by the diffuser 22 and atomized into aerosol by the heat of the heater 23 and released. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0558] In another embodiment, the heater 23 is fixed to the surface of the diffuser 22 facing the first opening 211 , and the diffuser 22 has a surface partially exposed from the heater 23 , so that the aerosol matrix flowing out of the liquid hole 121 can contact the diffuser 22 and be absorbed by the diffuser 22 .

[0559] In one embodiment, as shown in Figures 38, 47, and 48, the cigarette rod 20 further includes a push rod 24, which is fixed to the surface of the diffuser 22 and extends away from the diffuser 22. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the push rod 24 can extend into the liquid outlet 121 and push the sealing plug 151 to move in the first direction 001 away from the liquid outlet 121, thereby opening the liquid outlet 121 and enabling the cigarette rod 20 to release the aerosol matrix from the cigarette cartridge 10.

[0560] As shown in Figures 38, 47, and 48, the second housing 21 further includes a bottom cover 212, which is fixed to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. As will be appreciated, external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol atomized from the heater 23.

[0561] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the first opening 211 and the bottom cover 212 along the first direction 001. A connecting hole 2131 is defined in the fixing plate 213, and the connecting hole 2131 is connected to the air inlet 2121, so that air entering through the air inlet 2121 can be discharged through the connecting hole 2131 and out of the first opening 211.

[0562] In one embodiment, as shown in Figures 38, 47 and 48, the cigarette rod 20 also includes a battery 26, which is fixed to one end of the bottom cover 212 facing the first opening 211, and when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the two poles of the battery 26 are respectively electrically connected to the heating element 23 to provide electrical energy to the heating element 23.

[0563] Meanwhile, in the first direction 001, the battery 26 is spaced apart from the bottom cover 212. In the second direction 002 and the third direction 003, the battery 26 is also spaced apart from the second housing 21. The gap between the battery 26 and the inner wall of the second housing 21 forms an air intake passage 31. As will be appreciated, external air can be transmitted through the air intake holes 2121 and the air intake passage 31 to the first opening 211.

[0564] In one embodiment, the cigarette rod 20 further includes a positioning rod 25 , wherein one end of the positioning rod 25 is fixedly connected to the diffuser 22 , and the other end of the positioning rod 25 extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the diffuser 22 .

[0565] In one embodiment, as shown in FIG. 47 and FIG. 48 , the positioning rod 25 and the push rod 24 are an integral structure.

[0566] In one embodiment, as shown in Figures 38, 47, and 48, the cigarette holder 20 further includes a conductive post 271 and a connecting wire 272. One end of each conductive post 271 passes through the fixing plate 213 and is electrically connected to a terminal of the battery 26 via a connecting wire 272, while the other end extends toward the first opening 211. When the cigarette cartridge 10 and cigarette holder 20 are assembled as one, the two conductive posts 271 abut against and conduct electricity to the heater 23, thereby achieving an electrical connection between the battery 26 and the heater 23, thereby realizing the atomization function of the cigarette cartridge 10.

[0567] In one embodiment, as shown in Figures 47 and 48 , the cigarette holder 20 further includes a sensor 281, and a sensing hole 2122 is provided on the bottom cover 212. The sensing hole 2122 communicates between the outside air and the air inlet passage 31. The sensor 281 is fixedly attached to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 281 is electrically connected to a terminal of the battery 26, and the other end is electrically connected to a connecting wire 272.

[0568] When external air enters the air inlet channel 31 through the air inlet hole 2121, some air also enters the air inlet channel 31 through the sensing air hole 2122. This air can trigger the sensor 281 to connect the battery 26, the terminal, and the connecting wire 272, thereby realizing current transmission between the battery 26 and the heating element 23, and realizing the atomization function of the electronic cigarette 100.

[0569] When external air does not enter the air inlet passage 31 through the sensing holes 2122, the sensor 281 disconnects the electrical connection between the battery 26 and the connecting wire 272. It is understood that the electronic cigarette 100 of the present application can utilize the user's puffing action to switch the current between the battery 26 and the heating element 23, thereby controlling the heat generated by the heating element 23, thereby improving the user experience.

[0570] In one embodiment, as shown in Figures 47 and 48, the cigarette holder 20 further includes a buffer 282, which is placed between the battery 26 and the bottom cover 212, and the sensor 281 is fixed to the buffer 282. The buffer 282 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 2121.

[0571] It can be understood that the setting of the buffer member 282 not only satisfies the airflow transmission at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 26 and the sensor 281, reduces the impact of external forces on the battery 26 and the sensor 281, and ensures the atomization function of the electronic cigarette 100 of the present application.

[0572] In one embodiment, as shown in Figures 47 and 48, the cigarette rod 20 also includes a second seal 29, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 26 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 26 and ensuring the use of the electronic cigarette 100 of the present application.

[0573] In the prior art, an electronic cigarette generally includes a shell and an atomizer assembly. An oil storage tank is provided in the shell. An aerosol matrix is ​​set in the oil storage tank, and the aerosol matrix in the oil storage tank is atomized and released into an aerosol by the atomizer assembly, so that the aerosol is mixed with air and then output to the outside.

[0574] However, in the existing technology, the atomization component directly absorbs the aerosol matrix flowing out of the oil storage tank. When the cigarette cartridge is in different postures, the flow rate of the aerosol matrix may change with the change of the force direction of the aerosol matrix, thereby affecting the release effect of the electronic cigarette on the aerosol matrix.

[0575] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette cartridge that improves the release effect of the aerosol matrix, and an electronic cigarette including the cartridge, which specifically includes the following technical solutions.

[0576] In the first aspect, an embodiment of the present application provides an electronic cigarette cartridge, comprising a first shell and a liquid guiding member, the first shell being provided with an oil storage tank and a liquid outlet connected to the oil storage tank, the oil storage tank being used to store an aerosol matrix, the liquid guiding member having a porous structure, the liquid guiding member shielding the liquid outlet, and the aerosol matrix can be precipitated out of the oil storage tank through the liquid guiding member.

[0577] The cigarette cartridge of the present application is provided with an oil storage tank having a liquid outlet hole so that the aerosol matrix in the oil storage tank can be released to the opening through the liquid outlet hole, thereby realizing the release function of the cigarette cartridge of the present application on the aerosol matrix.

[0578] The present cigarette cartridge also fixes the liquid guide to the oil storage tank and covers the liquid outlet, so that the liquid guide can precipitate the aerosol matrix in the oil storage tank and guide the aerosol matrix in a direction away from the oil storage tank, thereby realizing the release process of the aerosol matrix from the present cigarette cartridge. At the same time, because the liquid guide is made of porous material, and the porous material has a certain storage function for the aerosol matrix, the liquid guide provided in the present cigarette cartridge can also reduce the influence of the cigarette cartridge's posture on the release rate of the aerosol matrix, ensure the amount of aerosol matrix released by the present cigarette cartridge, and improve the release effect of the aerosol matrix from the present cigarette cartridge.

[0579] In one embodiment, the cigarette cartridge includes a partition, which is arranged in the first shell and enclosed with the first shell to form an oil storage tank, and the liquid outlet is arranged on the partition.

[0580] In one embodiment, the liquid guiding member is fixed to a surface of the partition away from the oil storage tank, and the liquid guiding member is used to shield the liquid outlet hole.

[0581] In one embodiment, the liquid guiding member and the first shell are combined to form an oil storage tank, and the liquid outlet is provided on the liquid guiding member.

[0582] In one embodiment, the cigarette cartridge further includes a sealing member, which is located on a surface of the liquid-guiding member away from the oil storage bin, and the sealing member at least partially covers the liquid-guiding member.

[0583] In a second aspect, an embodiment of the present application provides an electronic cigarette, comprising a cigarette rod and a cigarette cartridge, wherein the cigarette rod comprises a heating component, and the heating component is used to heat an aerosol matrix.

[0584] In one embodiment, the heating assembly includes a diffuser and a heating element. The heating assembly is used to heat the diffuser, and the diffuser is used to increase the heating area of ​​the heating assembly.

[0585] In one embodiment, the diffuser and the liquid guide are spaced apart from each other; the heating element is located on the side of the diffuser facing away from the liquid guide; or the diffuser includes a heating surface facing the liquid guide, and the heating element is provided on the heating surface.

[0586] In one embodiment, the diffuser has a porous structure.

[0587] In one embodiment, the porosity of the liquid guiding member is greater than the porosity of the diffuser.

[0588] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette cartridge provided in the first aspect of the present application, it also has the beneficial effect of enhancing the release effect of the aerosol matrix.

[0589] Please refer to FIG. 49 for a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0590] As shown in FIG49 , the electronic cigarette 100 of the present application includes a cartridge 10 and a cigarette rod 20. The cartridge 10 includes a first housing 111, and the cigarette rod 20 includes a second housing 21. An oil storage tank 12 is provided within the first housing 111, and an aerosol matrix is ​​stored within the oil storage tank 12. The second housing 21 has a first opening 211, through which the cartridge 10 can partially extend into the first housing 111.

[0591] The electronic cigarette 100 of the present application also includes an air circuit 30, which connects two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposite sides of the electronic cigarette 100, allowing external air to enter from the other side of the electronic cigarette 100. The air is mixed with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and then enters the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0592] When the cigarette cartridge 10 and cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, forming an atomization chamber 33 between the cigarette cartridge 10 and the cigarette rod 20. The air inlet channel 31 is located in the second shell 21, and the air outlet channel 32 is located in the first shell 111. The air inlet channel 31 communicates between the air inlet hole 2121 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 1121 and the atomization chamber 33.

[0593] As will be understood, when a user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, external air enters the air inlet channel 31 through the air inlet 2121 of the cigarette rod 20 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the second housing 21 flows toward the heating assembly 22 of the cigarette rod 20, absorbing the heat generated by the heating assembly 22 and atomizing into an aerosol. The aerosol mixes with the external air and, as the user inhales, flows along the air outlet channel 32 from the air outlet 1121 into the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0594] For details, please refer to FIG50 , which shows a schematic diagram of the structure of a cigarette cartridge 10 provided in one embodiment of the present application. Also refer to FIG49 . For ease of description, the cigarette cartridge 10 and cigarette rod 20 in FIG49 are arranged in a first direction 001 , with a second direction 002 perpendicular to the first direction 001 .

[0595] As shown in Figures 49 and 50, the cigarette cartridge 10 of the present application further includes an oil storage bin 12, which is housed within the first housing 111 and is used to store aerosol substrate. A liquid outlet 121 is provided on the oil storage bin 12, connecting the oil storage bin 12 with the external environment so that the aerosol substrate stored in the oil storage bin 12 can flow out through the liquid outlet 121.

[0596] The cigarette cartridge 10 further includes a liquid guide 13 , which is fixed to the oil storage bin 12 and covers the liquid outlet 121 , and extends along a first direction 001 away from the oil storage bin 12 .

[0597] As shown in Figures 49 and 50 , the liquid outlet 121 is blocked by the liquid guide 13, allowing the aerosol substrate stored in the oil storage tank 12 to contact the liquid guide 13 through the liquid outlet 121. The liquid guide 13 has a porous structure. As will be appreciated, the liquid guide 13 is capable of directing the aerosol substrate within the oil storage tank 12 out of the oil storage tank 12 and away from the oil storage tank 12.

[0598] As shown in Figure 49, when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, one end of the liquid guide 13 is close to the heating component 22 of the cigarette rod 20 to absorb the heat generated by the heating component 22, thereby atomizing the aerosol matrix that flows to the side of the liquid guide 13 close to the heating component 22 and releasing the aerosol.

[0599] During use of the electronic cigarette 100 of the present application, it is necessary to ensure that the aerosol content released from the electronic cigarette 100 is relatively consistent to ensure a good user experience. The aerosol content released is related to the content of the aerosol matrix released and atomized by the cigarette cartridge 10 of the present application. Due to the fluidity of the aerosol matrix, the amount of aerosol matrix entering the liquid outlet 121 is relatively limited when the cigarette cartridge 10 is in different postures.

[0600] In the prior art, a diffuser made of porous material is usually placed directly near the liquid outlet, and a heater is fixed to the diffuser. The aerosol matrix flows out of the liquid outlet due to gravity, flows to the diffuser, is absorbed by the diffuser, and then atomized into an aerosol under the action of the heater. However, when the user changes the posture of using the e-cigarette, the direction of gravity acting on the aerosol matrix may cause an angle between the arrangement of the cartridge and the cigarette rod, resulting in a decrease in the flow rate of the aerosol matrix flowing out of the liquid outlet, a decrease in the flow rate, and thus a decrease in the amount of aerosol matrix atomized, affecting the user experience.

[0601] Thus, the cigarette cartridge 10 of the present application is provided with a liquid guide 13 having a porous structure, and the liquid guide 13 is arranged on the oil storage bin 12 and blocks the liquid outlet 121, so that the liquid guide 13 can precipitate the aerosol matrix in the oil storage bin 12, thereby avoiding the influence of the cigarette cartridge 10 on the release rate of the aerosol matrix caused by the change of the cigarette cartridge 10 posture. In addition, the aerosol release amount of the cigarette cartridge 10 of the present application is guaranteed, and the release effect of the aerosol matrix of the cigarette cartridge 10 of the present application is improved.

[0602] At the same time, the liquid guide 13 also has a certain liquid storage function, and the liquid guide 13's release of aerosol matrix does not stop regardless of whether the electronic cigarette 100 is in use. When the user uses the electronic cigarette 100, the aerosol matrix stored in the liquid guide 13 can be atomized into aerosol as the user inhales. This improves the efficiency of the aerosol matrix release of the cigarette cartridge 10 of the present application and enhances the user experience.

[0603] In one embodiment, as shown in Figures 49 and 50, the cigarette cartridge 10 of the present application further includes a partition 122, which is fixed in the first shell 111 and cooperates with the first shell 111 to form the oil storage bin 12. The liquid outlet 121 is provided on the partition 122. The liquid guide 13 is attached to the surface of the partition 122 away from the inner side of the oil storage bin 12 and shields the liquid outlet 121 to facilitate the precipitation of the aerosol matrix in the oil storage bin 12. It can be understood that the aerosol matrix stored in the oil storage bin 12 can be precipitated by the liquid guide 13 through the liquid outlet 121 and the partition 122.

[0604] Please refer to FIG. 51 for another structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application.

[0605] As shown in Figure 51, the liquid guide member 13 is fixed in the first shell 111 and cooperates with the first shell 111 to form the oil storage bin 12. The aerosol matrix directly contacts the surface of the liquid guide member 13, and the aerosol matrix can be directly precipitated by the liquid guide member 13 and guided in a direction away from the oil storage bin 12. It can be understood that the liquid guide member 13 cooperates with the first shell 111 to form the oil storage bin 12, which increases the contact area between the aerosol matrix and the liquid guide member 13, improves the precipitation speed of the aerosol matrix by the cigarette cartridge 10 of the present application, and further improves the release effect of the aerosol matrix by the cigarette cartridge 10 of the present application.

[0606] The liquid outlet 121 is provided on the liquid guide 13. Since the liquid guide 13 has a porous structure, it is understandable that the pores distributed in the liquid guide 13 are the liquid guide 13.

[0607] Please refer to FIG52 for another structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and refer to FIG49 and FIG50 for reference.

[0608] As shown in Figures 49, 50, and 52, the cigarette cartridge 10 of the present application further includes a seal 14. When the cigarette cartridge 10 and the cigarette rod 20 of the electronic cigarette 100 of the present application are separated from each other, the seal 14 is connected to the first housing 111. When the user needs to use the electronic cigarette 100, the seal 14 on the cigarette cartridge 10 is opened and the cigarette cartridge 10 and the cigarette rod 20 are assembled into one body.

[0609] Since the pores in the liquid guide 13 can be connected to the liquid outlet 121 and the external environment, the sealing member 14 covers the surface of the liquid guide 13 away from the oil storage tank 12, thereby preventing the aerosol matrix from leaking out of the liquid guide 13. This improves the sealing effect of the cigarette cartridge 10 on the aerosol matrix and enhances the user experience.

[0610] It can be understood that in another embodiment, when the pores in the liquid-guiding member 13 are also connected to the liquid outlet 121 and the side wall of the liquid-guiding member 13, and the side wall of the liquid-guiding member 13 is partially exposed, the sealing member 14 also covers the side wall of the liquid-guiding member 13 to prevent the aerosol matrix from leaking outward from the side wall of the liquid-guiding member 13.

[0611] In one embodiment, as shown in FIG50 and FIG51 , the cigarette cartridge 10 includes a third shell 112 , wherein the first shell 111 is received in the third shell 112 .

[0612] The third housing 112 further defines an air outlet 1121, which is located on a side of the third housing 112 away from the liquid outlet 121. The first housing 111 and the third housing 112 are spaced apart from each other to form an air outlet channel 32. The air outlet channel 32 is also connected to the air outlet 1121.

[0613] It is understood that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix precipitated on the liquid guide 13 can be atomized into an aerosol under the action of the heating assembly 22 of the cigarette rod 20, and flows from the atomization chamber 33 to the air outlet 1121 through the air outlet channel 32, and is output outward from the air outlet 1121. In this way, the user can inhale the electronic cigarette 100 of the present application.

[0614] In one embodiment, as shown in Figures 50 and 51 , a sealing opening 1111 is provided on a side of the first shell 111 away from the liquid outlet 121. The cartridge 10 further includes a sealing plate 15, which is fixed to and covers the sealing opening 1111. The first shell 111, the partition plate 122, and the sealing plate 15 cooperate to form the oil storage tank 12.

[0615] Please refer to FIG53 for a partial structural diagram of a cigarette cartridge 10 provided in one embodiment of the present application, and FIG54 for a partial cross-sectional diagram of a cigarette cartridge 10 provided in one embodiment of the present application. Please also refer to FIG50 .

[0616] As shown in Figures 50, 53, and 54, the cigarette cartridge 10 of the present application further includes a support member 16. The third shell 112 is cylindrical, and a plurality of support members 16 are provided. The plurality of support members 16 are spaced apart along the circumference of the third shell 112, and each support member 16 is fixed between the first shell 111 and the third shell 112.

[0617] A gap is left between each two adjacent support members 16 to form an air outlet channel 32. It can be understood that the mixed gas of aerosol and air in the atomization chamber 33 can be transmitted from between the two adjacent support members 16 to the air outlet hole 1121.

[0618] In one embodiment, as shown in Figures 53 and 54, the cigarette cartridge 10 further includes a liquid wicking member 17, which is disposed between each two adjacent support members 16 and spaced apart from at least one support member 16 to ensure that the mixed gas of aerosol and air in the atomization chamber 33 can be discharged. The liquid wicking member 17 can be used to absorb the aerosol matrix condensed during the transmission process, preventing the aerosol matrix from entering the mouth through the air outlet channel 32, thereby ensuring the user's usage experience.

[0619] Please refer to Figure 55, a schematic structural diagram of a cigarette rod 20 provided in one embodiment of the present application, and Figure 56, a schematic cross-sectional structural diagram of a cigarette rod 20 provided in one embodiment of the present application. Please also refer to Figure 49. Figures 55 and 56 are schematic structural diagrams of the cigarette rod 20 in different directions. To facilitate the relationship between Figures 55 and 56, a third direction 003 is provided that is perpendicular to both the first direction 001 and the second direction 002.

[0620] As shown in Figures 49, 55 and 56, the cigarette holder 20 of the present application further includes a heating assembly 22. The heating assembly 22 includes a diffuser 221 and a heater 222. When the cigarette cartridge 10 and the cigarette holder 20 are assembled as one, along the first direction 001, the diffuser 221 and the liquid guide 13 are spaced apart from each other, and the diffuser 221 includes a heating surface 2211 facing the first opening 211. The heating surface 2211 can receive the aerosol matrix flowing out of the diffuser 221 to prevent the aerosol matrix flowing out of the liquid guide 13 from flowing into the air path 30, thereby ensuring the user experience.

[0621] The heater 222 is fixed to the diffuser 221 to heat the diffuser 221 and atomize the aerosol matrix on the diffuser 221 into an aerosol, which is then released into the atomization chamber 33, thereby preventing the aerosol matrix from flowing out of the diffuser 22. Simultaneously, the heat from the heater 222 can also be transferred to the liquid guide 13 to atomize the aerosol matrix within the liquid guide 13. This achieves the aerosol matrix atomization function of the cigarette holder 20 of the present application.

[0622] Since the cross-sectional area of ​​the heating element 222 is smaller than that of the diffuser 221, it is understandable that the provision of the diffuser 221 can also increase the heating area of ​​the aerosol substrate by the heating element 222, thereby allowing more aerosol substrate to absorb the heat of the heating element 222 and be atomized into aerosol, thereby improving the atomization efficiency of the aerosol substrate of the cigarette holder 20 of the present application.

[0623] In one embodiment, the diffuser 221 has a porous structure. It is understood that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix flowing out of the liquid guide 13 can be absorbed by the heating surface 2211 while flowing to the heating surface 2211. Correspondingly, the heat from the heating element 222 can also heat the aerosol matrix absorbed by the diffuser 221, thereby achieving the atomization function of the cigarette rod 20 of the present application.

[0624] In one embodiment, as shown in Figures 49, 55 and 56, the heating element 222 is fixed to the surface of the diffuser 221 away from the first opening 211. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix in the oil storage tank 12 is precipitated by the liquid guide member 13 through the liquid outlet 121. Among them, part of the aerosol matrix is ​​atomized into aerosol and released by the heat released by the diffuser 221 after being heated by the heating element 222, and another part of the aerosol matrix flows out of the liquid guide member 13 and is absorbed by the heating surface 2211. This part of the aerosol matrix is ​​atomized into aerosol and released under the action of the heat of the heating element 222. Thereby, the atomization function of the electronic cigarette 100 of the present application is realized.

[0625] Please refer to FIG57 , which is a schematic diagram of a partial cross-sectional structure of a cigarette rod 20 provided in one embodiment of the present application, and please refer to FIG58 , which is a schematic diagram of a partial structure of a cigarette rod 20 provided in one embodiment of the present application.

[0626] As shown in Figures 57 and 58, the heating element 222 is fixed on the heating surface 2211 of the diffuser 221, and a portion of the heating surface 2211 is exposed, so that the aerosol matrix flowing out of the liquid guide 13 can flow into the heating surface 2211 and be absorbed by the heating surface 2211.

[0627] When the cigarette cartridge 10 and cigarette holder 20 are assembled, the aerosol matrix in the oil reservoir 12 is discharged by the liquid guide 13 through the liquid outlet 121. Part of the aerosol matrix directly absorbs the heat released by the heating element 222, atomizing into an aerosol and releasing it. Another part of the aerosol matrix flows out of the liquid guide 13 and is absorbed by the heating surface 2211. This part of the aerosol matrix is ​​atomized into an aerosol under the action of the heat of the heating element 222 and released. This achieves the atomization function of the electronic cigarette 100 of the present application.

[0628] In one embodiment, both the liquid-guiding member 13 and the diffuser 221 are made of porous materials, and the porosity of the liquid-guiding member 13 is greater than that of the diffuser 221. Since the porosity is related to the liquid absorption and permeability of the material, the greater the porosity of the material, the greater the number of closed pores, the smaller the pore diameter, the stronger the liquid absorption and permeability of the material.

[0629] Since more aerosol substrate enters the liquid-guiding member 13 than the diffuser 221, it is understandable that the liquid-guiding member 13 having a higher porosity can enable the aerosol substrate released from the liquid outlet 121 to be absorbed relatively quickly, thereby ensuring the release efficiency of the aerosol substrate by the cartridge 10 of the electronic cigarette 100 of the present application.

[0630] At the same time, since the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-guiding member 13 can also diffuse into the entire liquid-guiding member 13 more quickly, thereby achieving a match between the heat released by the heating member 222 and the diffuser 221 and the amount of aerosol matrix guided toward the heating member 222, thereby ensuring the amount of aerosol released by the electronic cigarette 100 of the present application.

[0631] When some aerosol matrix overflows onto the surface of the diffuser 221 and is absorbed by the heating surface 2211, the porosity of the diffuser 221 is smaller than that of the liquid guide 13. The aerosol matrix overflowing onto the surface of the diffuser 221 is absorbed by the absorbing diffuser at a relatively slow penetration rate. Because the temperature decreases with increasing distance from the heating element 222, the amount of heat absorbed by the aerosol matrix will also decrease accordingly. It is understandable that providing a diffuser 221 with a smaller porosity can reduce the penetration rate of the aerosol matrix, thereby extending the penetration time of the aerosol matrix, so that the aerosol matrix can absorb more heat to atomize and form an aerosol.

[0632] That is, the matching setting of the porosity of the diffuser 221 and the liquid-guiding member 13 increases the amount of heat absorbed by the aerosol matrix from the heating element 222, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and improving the user experience of using the electronic cigarette 100 of the present application.

[0633] In one embodiment, as shown in Figures 55 and 56 , the second housing 21 further includes a bottom cover 212, which is fixed to an end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. The bottom cover 212 is provided with an air inlet 2121. As will be appreciated, external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol released from the liquid-guiding member 13.

[0634] In one embodiment, as shown in Figures 55 and 56, the cigarette rod 20 further includes a battery 24, which is fixed to one end of the bottom cover 212 facing the first opening 211, and the two poles of the battery 24 are respectively electrically connected to the heating element 222 to provide electrical energy to the heating element 222.

[0635] At the same time, in the first direction 001, the battery 24 is spaced apart from the bottom cover 212. In the third direction 003, the battery 24 is also spaced apart from the second housing 21. The gaps between the battery 24 and the bottom cover 212, and between the battery 24 and the second housing 21, form an air inlet passage 31. As will be appreciated, external air can be transmitted through the air inlet holes 2121 and the air inlet passage 31 to the atomization chamber 33.

[0636] In one embodiment, the second housing 21 further includes a fixing plate 213, which is located between the battery 24 and the diffuser 221. The fixing plate 213 is provided with a communication hole 2131, so that the air entering through the air inlet hole 2121 can be discharged from the communication hole 2131 via the air inlet channel 31.

[0637] In one embodiment, the cigarette rod 20 further includes a positioning rod 23 , wherein one end of the positioning rod 23 is fixedly connected to the diffuser 221 , and the other end of the positioning rod 23 extends toward the fixing plate 213 and is fixed to the fixing plate 213 , thereby achieving positioning of the diffuser 221 .

[0638] In one embodiment, as shown in Figures 55 and 56, the cigarette rod 20 further includes a conductive column 251 and a connecting wire 252. One end of the conductive column 251 is in contact with the heating element 222 for conduction, and the other end of the conductive column 251 is fixed to and passes through the fixing plate 213, and is electrically connected to the two poles of the battery 24 through a connecting wire 252 respectively.

[0639] It can be understood that the electric energy inside the battery 24 is transmitted to the corresponding connecting wires 252 via the two poles, and then transmitted to the heating element 222 via the connecting wires 252 and the conductive column 251 in sequence, thereby realizing the atomization function of the cigarette rod 20.

[0640] In one embodiment, as shown in Figures 55 and 56 , the cigarette holder 20 further includes a sensor 261, and a sensing hole 2122 is provided on the bottom cover 212. The sensing hole 2122 communicates between the outside air and the air inlet passage 31. The sensor 261 is fixedly attached to the bottom cover 212 and covers the sensing hole 2122. One end of the sensor 261 is electrically connected to a terminal of the battery 24, and the other end is electrically connected to a connecting wire 252.

[0641] When external air enters the air inlet channel 31 through the air inlet hole 2121, some air also enters the air inlet channel 31 through the sensing air hole 2122. This air can trigger the sensor 261 to connect the battery 24, the terminal, and the connecting wire 252, thereby realizing the current transmission between the battery 24 and the heating element 222, and realizing the atomization function of the cigarette rod 20.

[0642] When external air does not enter the air inlet passage 31 through the sensing air holes 2122, the sensor 261 disconnects the electrical connection between the battery 24 and the connecting wire 252. It is understood that the cigarette holder 20 of the present application can utilize the user's puffing action to switch the current between the battery 24 and the heating element 222, thereby controlling the heat generated by the heating element 222, thereby improving the user experience.

[0643] In one embodiment, as shown in Figures 55 and 56 , the cigarette holder 20 further includes a buffer 262, which is placed between the battery 24 and the bottom cover 212, and the sensor 261 is fixed to the buffer 262. The buffer 262 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 2121.

[0644] It can be understood that the setting of the buffer member 262 not only meets the airflow transmission requirements at the opposite ends of the cigarette rod 20 of the present application, but also cooperates with the bottom cover 212 to protect the battery 24 and the sensor 261, reducing the impact of external forces on the battery 24 and the sensor 261, and ensuring the atomization function of the cigarette rod 20 of the present application.

[0645] In one embodiment, as shown in Figures 55 and 56, the cigarette rod 20 also includes a second seal 27, which is fixed to the surface of the fixing plate 213 facing the first opening 211 to prevent the released aerosol from condensing and leaking into the battery 24 through the gap between the fixing plate 213 and the second shell 21, thereby avoiding the influence of the condensed aerosol matrix on the battery 24 and ensuring the use of the electronic cigarette 100 of the present application.

[0646] In the prior art, an e-cigarette typically consists of a cartridge and a stem. The cartridge houses an atomizer assembly, while the stem houses a battery that is electrically connected to the atomizer assembly's heater. The cartridge also stores an aerosol matrix, which is absorbed by the atomizer assembly and released as aerosol under the action of the heater. The released aerosol mixes with air and is then discharged from the cartridge's mouthpiece.

[0647] To extend the lifespan of e-cigarettes, a single cigarette holder is typically paired with multiple cartridges. When the aerosol matrix in a single cartridge is depleted, a new cartridge can be replaced for continued use. However, in existing technologies, the atomizer assembly within the cartridge is also wasted when the cartridge is discarded, increasing the cost of using the e-cigarette for users.

[0648] In view of the above-mentioned deficiencies in the prior art, the present application aims to provide an electronic cigarette rod assembly with reduced usage costs, and an electronic cigarette including the electronic cigarette rod assembly, which specifically includes the following technical solutions.

[0702] In one embodiment, an air inlet is provided on a side of the second shell away from the first opening, and the air inlet is connected to the first opening so that air entering from the air inlet can be mixed with the aerosol formed by atomization of the heating element.

[0716] It can be understood that since the electronic cigarette provided in the second aspect of the present application adopts the cigarette rod assembly provided in the first aspect of the present application, it also has the beneficial effect of improving the atomization efficiency.

[0717] Please refer to FIG. 59 for a schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application.

[0718] As shown in FIG59 , the electronic cigarette 100 of the present application includes a cigarette rod assembly 10 and a cigarette cartridge 20. The cigarette cartridge 20 includes a first housing 211, within which is disposed an oil storage tank 22. The oil storage tank 22 stores an aerosol matrix. The cigarette rod assembly 10 includes a second housing 111, which is provided with a first opening 1111. The cigarette cartridge 20 can partially extend into the first housing 211 through the first opening 1111.

[0719] The electronic cigarette 100 of the present application also includes an air circuit 30, which connects two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, a pressure difference is formed on the opposite sides of the electronic cigarette 100, allowing external air to enter from the other side of the electronic cigarette 100. The air is mixed with the aerosol released by the atomized aerosol matrix inside the electronic cigarette 100 and then enters the user's mouth, thereby realizing the inhalation function of the electronic cigarette 100 of the present application. The air circuit 30 includes an air inlet channel 31, an air outlet channel 32, and an atomization chamber 33.

[0720] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the second housing 111 extends into the first inner cavity 21a of the first housing 211, forming an atomization chamber 33 between the cigarette cartridge 20 and the cigarette rod assembly 10. The air inlet channel 31 is located in the second housing 111, and the air outlet channel 32 is located in the first housing 211. The air inlet channel 31 communicates between the air inlet hole 1112 and the atomization chamber 33, while the air outlet channel 32 communicates between the air outlet hole 2121 and the atomization chamber 33.

[0721] It is understood that when a user inhales the electronic cigarette 100 of the present application through the air outlet 2121 of the cigarette cartridge 20, external air enters the air inlet channel 31 through the air inlet 1112 of the cigarette rod assembly 10 and enters the atomization chamber 33 along the air inlet channel 31. The aerosol matrix stored in the first shell 211 flows toward the heating element 13 of the cigarette rod assembly 10 and absorbs the heat generated by the heating element 13 to be atomized into aerosol. The aerosol mixes with the external air and, as the user inhales, enters the user's mouth through the air outlet 2121 along the air outlet channel 32, thereby realizing the inhalation function of the electronic cigarette 100 of the present application.

[0722] Specifically, please refer to FIG60 for a schematic structural diagram of a cigarette rod assembly 10 provided in one embodiment of the present application, and refer to FIG61 for a schematic cross-sectional structural diagram of a cigarette rod assembly 10 provided in one embodiment of the present application. For ease of description, FIG59 and subsequent figures set the arrangement direction of the cigarette cartridge 20 and the cigarette rod assembly 10 as a first direction 001, and set a second direction 002 perpendicular to the first direction 001. In FIG61, in order to facilitate the relationship between FIG60 and FIG61, a third direction 003 perpendicular to the first direction 001 and the second direction 002 is set.

[0723] As shown in Figures 60 and 61, the cigarette rod assembly 10 of the present application includes a cigarette rod 11, a support member 12 and a heating member 13. The cigarette rod 11 includes a second shell 111. Among them, the support member 12 is connected to the cigarette rod 11 and is accommodated in the second shell 111. The support member 12 can be made of a porous material. When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the aerosol matrix in the cigarette cartridge 20 will enter the second shell 111 from the first opening 1111 and flow onto the support member 12. The aerosol matrix flowing onto the support member 12 will be absorbed by the support member 12 and diffused to various positions of the support member 12 in all directions.

[0724] The heating element 13 is also housed within the second housing 111 and mounted on the support member 12. When the heating element 13 releases heat, the temperature of the support member 12 increases. As will be appreciated, the heat released by the heating element 13 is transferred to the aerosol matrix via the support member 12, atomizing the aerosol matrix into an aerosol that is released into the atomization chamber 33. This achieves the atomization function of the cigarette rod assembly 10 of the present application.

[0725] As shown in Figures 59-61, the support member 12 has a liquid absorption surface 121. The liquid absorption surface 121 is the surface of the support member 12 facing the first opening 1111. It will be understood that when the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the aerosol matrix in the cigarette cartridge 20 will flow into the second housing 111 along the first direction 001 and onto the liquid absorption surface 121, where it will be absorbed by the liquid absorption surface 121.

[0726] Please refer to FIG62 for a partial structural diagram of a cigarette rod assembly 10 provided in one embodiment of the present application, and FIG63 for a partial cross-sectional diagram of a cigarette rod assembly 10 provided in one embodiment of the present application.

[0727] As shown in Figures 59, 62, and 63, the heating element 13 is disposed on the liquid absorbing surface 121 of the support member 12, with a portion of the liquid absorbing surface 121 exposed, so that the aerosol matrix flowing in from the first opening 1111 can contact the liquid absorbing surface 121 and be absorbed by the support member 12.

[0728] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the surface of the heating element 13 facing the first opening 1111 is close to the cigarette cartridge 20. The aerosol matrix in the oil storage tank 22 flows from the first opening 1111 into the second shell 111. Part of the aerosol matrix directly absorbs the heat released by the heating element 13 and is atomized into aerosol and released. Another part of the aerosol matrix is ​​absorbed by the support member 12. This part of the aerosol matrix is ​​atomized into aerosol under the action of the heat of the heating element 13 and is released. This realizes the atomization function of the cigarette rod assembly 10 of the present application.

[0729] It should be understood that the heating element 13 is arranged on the liquid absorption surface 121 as only one embodiment of the present application. In other embodiments, the heating element 13 can be arranged on the side of the support member 12 away from the liquid absorption surface 121, or the heating element 13 can be at least partially arranged inside the support member 12. As long as the heating element 13 can heat the aerosol matrix to release the aerosol, the present application does not limit the specific setting position of the heating element 13.

[0730] In one embodiment, as shown in FIG. 59 , FIG. 62 and FIG. 63 , the heating element 13 is annular, and the annular heating element 13 allows the heating element 13 to fit the surface of the support member 12 close to the side wall of the support member 12 .

[0731] It can be understood that when the heating element 13 releases heat outward, the temperature of the area corresponding to the surface of the support member 12 in contact with the heating element 13 will be relatively high, so that the area close to the side wall of the support member 12 has a higher temperature, so that the aerosol matrix near the side wall absorbed by the support member 12 can be atomized more quickly to form an aerosol and released outward from the side wall.

[0732] As shown in Figure 59, when the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the support member 12 will be located in the atomization chamber 33, and the side wall of the support member 12 will be exposed in the atomization chamber 33. When external air enters the atomization chamber 33, the air will be transmitted toward the side wall of the support member 12 along the second direction 002 and the third direction 003. Based on the fact that air flows as the user inhales, and aerosol is released outward under a certain temperature environment. It can be understood that the flow rate of air in the atomization chamber 33 is higher than the release rate of the aerosol, so that when the air flows to the side wall of the support member 12, it will promote the mixing of aerosol and air, thereby improving the mixing quality of aerosol and air and improving the user's taste.

[0733] That is, the aerosol released from the sidewall of the support member 12 directly contacts and mixes with the incoming air. It is understood that the provision of the annular heating element 13 enables the atomized aerosol to be released from the sidewall of the support member 12, thereby improving the mixing quality of the aerosol and air in the cigarette rod assembly 10 of the present application and enhancing the user experience.

[0734] In one embodiment, the radius difference between the outer ring and the inner ring of the annular heating element 13 is between 0.8 mm and 1.5 mm. It is understood that when this range is less than 0.8 mm, the range of heat release from the heating element 13 to the support member 12 is reduced. When heat is transferred into the support member 12, the heat is also transferred to other areas not covered by the heating element 13, resulting in a relatively low temperature on the side wall of the support member 12, thereby affecting the atomization effect.

[0735] When this range is greater than 1.5 mm, the radius of the inner ring is reduced, thereby reducing the amount of aerosol substrate absorbed by the support member 12 and the gap between the heater 13 and the push rod 15. Since there is an upper limit to the amount of aerosol substrate that the support member 12 can absorb, it is understandable that when aerosol substrate is collected in the smaller gap between the heater 13 and the push rod 15, the aerosol substrate may cause electrical conduction between the heater 13 and the push rod 15, potentially affecting the operation of the heater 13.

[0736] That is, the radius difference between the outer ring and the inner ring of the annular heating element 13 is set between 0.8mm and 1.5mm. While ensuring the heating function of the heating element 13, it can also avoid affecting the heating effect of the side wall of the support member 12 due to the small heating area, thereby affecting the atomization effect of the cigarette rod assembly 10 of the present application.

[0737] In one embodiment, as shown in Figures 59, 62, and 63, the cigarette holder 11 includes a battery 112, which is electrically connected to the heating element 13 to provide energy for the heating element 13 to generate heat. In the first direction 001, the support member 12 is located between the battery 112 and the heating element 13, that is, the heating element 13 is located on the side of the support member 12 facing away from the battery 112 (as shown on the upper surface in Figure 63).

[0738] In this embodiment, the cigarette rod 11 includes a transmission member 113, which is electrically connected to the battery 112 and the heating member 13. One end of the transmission member 113 is electrically connected to the battery 112, and the other end passes through the support member 12 and is electrically connected to the heating member 13, thereby realizing the electrical connection between the battery 112 and the heating member 13.

[0739] In one embodiment, as shown in Figures 59, 62 and 63, two through holes 122 are provided on the support member 12, which penetrate and are spaced apart from each other. Each transmission member 113 includes a conductive segment 1131 and a supporting segment 1132. The conductive segment 1131 of each transmission member 113 is respectively filled in a through hole 122 to ensure the electrical connection between the transmission member 113 and the heating member 13. The supporting segment 1132 is electrically connected to the battery 112. At the same time, the supporting segment 1132 is also attached to the surface of the support member 12 away from the liquid absorption surface 121, and covers the corresponding through hole 122, and the supporting segment 1132 is also electrically connected to the conductive segment 1131.

[0740] It can be understood that the arrangement of the abutting section 1132 can not only ensure the electrical connection between the battery 112 and the transmission member 113 , but also support the support member 12 , thereby ensuring the relative position of the heating member 13 .

[0741] In one embodiment, the transmission element 113 is a wire, and the heating element 13 and the battery 112 are connected by the wire, so that the heating element 13 can be flexibly arranged.

[0742] Please refer to FIG. 64 for another partial structural diagram of a cigarette rod assembly 10 provided in one embodiment of the present application, and FIG. 65 for another partial cross-sectional diagram of a cigarette rod assembly 10 provided in one embodiment of the present application. Please also refer to FIG. 59 .

[0743] As shown in Figures 59, 64 and 65, along the second direction 002, two grooves 123 spaced apart from each other are provided on the side wall of the support member 12, one end of each transmission member 113 is embedded in a groove 123 and electrically connected to the heating member 13, and the other end of each transmission member 113 is electrically connected to the battery 112.

[0744] As will be appreciated, the groove 123 provided on the sidewall of the support member 12 allows the transmission member 113 to pass through the support member 12, electrically connecting the battery 112 and the heating element 13 on opposite sides of the support member 12, while also reducing the difficulty of machining the support member 12. Furthermore, the transmission member 113 can extend along the second direction 002 away from the support member 12, thereby ensuring electrical connection between the battery 112 and the transmission member 113 while also supporting the support member 12 and thereby maintaining the relative position of the heating element 13.

[0745] Please refer to FIG. 66 for another partial structural diagram of the cigarette rod assembly 10 provided in one embodiment of the present application, and FIG. 67 for another partial cross-sectional diagram of the cigarette rod assembly 10 provided in one embodiment of the present application.

[0746] As shown in Figures 59, 66, and 67, the heating element 13 is fixed to the surface of the support member 12 facing away from the first opening 1111. The heating element 13 is used to heat the support member 12. When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the aerosol matrix enters the second housing 111 through the first opening 1111. The heating element 13 heats the support member 12, which also reaches a relatively high temperature.

[0747] It is understood that part of the aerosol matrix will be atomized into an aerosol under the influence of the surface temperature of the support member 12 before flowing to the liquid absorption surface 121, while another part of the aerosol matrix will flow to the liquid absorption surface 121 and be absorbed by the support member 12. This part of the aerosol matrix will be atomized into an aerosol under the influence of the heat of the heating element 13 and released. In this way, the atomization function of the cigarette rod assembly 10 of the present application is realized.

[0748] On the other hand, since the cross-sectional area of ​​the heating element 13 is smaller than that of the support element 12, it can be understood that the provision of the support element 12 increases the diffusion range of the heat of the heating element 13, thereby increasing the heating area of ​​the aerosol substrate by the cigarette rod assembly 10 of the present application, and improving the atomization effect of the aerosol substrate by the cigarette rod assembly 10 of the present application.

[0749] It is understandable that when the heating element 13 is fixed to the surface of the support member 12 away from the first opening 1111 , the battery 112 is located on the side of the heating element 13 away from the support member 12 , so as to facilitate electrical connection between the battery 112 and the heating element 13 .

[0750] In one embodiment, the heating element 13 is made of metal.

[0751] In one embodiment, the heating element 13 is a conductive material layer.

[0752] In one embodiment, the support member 12 is made of ceramic.

[0753] In one embodiment, the support member 12 is detachably connected to the cigarette rod 11. When the support member 12 is damaged, the support member 12 can be removed from the cigarette rod 11 and replaced, thereby increasing the service life of the cigarette rod assembly 10 and improving the user experience.

[0754] In one embodiment, referring back to Figures 59 to 61 , the cigarette rod 11 further includes a bottom cover 114 , which is fixed to an end of the second shell 111 away from the first opening 1111 to cooperate with the second shell 111 to form a second inner cavity 11a .

[0755] The battery 112 is fixed to one end of the bottom cover 114 facing the first opening 1111 and is spaced apart from the bottom cover 114 in the first direction 001. In the third direction 003, the battery 112 is also spaced apart from the second housing 111. In other words, the gaps between the battery 112 and the bottom cover 114, and between the battery 112 and the second housing 111, cooperate to form the air intake passage 31.

[0756] The air inlet hole 1112 is provided on the bottom cover 114 . It is understood that external air can be transmitted to the first opening 1111 through the air inlet hole 1112 and the air inlet channel 31 , and then transmitted to the atomization chamber 33 .

[0757] In one embodiment, as shown in Figures 59-61, the cigarette holder 11 further includes a fixing plate 115, which is located between the battery 112 and the support member 12. A connecting hole 1151 is provided on the fixing plate 115, so that air entering through the air inlet hole 1112 can be discharged from the connecting hole 1151 via the air inlet channel 31.

[0758] In one embodiment, the cigarette rod assembly 10 further includes a positioning rod 14 , wherein one end of the positioning rod 14 is fixedly connected to the support member 12 , and the other end of the positioning rod 14 extends toward and is fixed to the fixing plate 115 , thereby achieving positioning of the support member 12 and the heating member 13 .

[0759] In one embodiment, as shown in Figures 59-61, the cigarette rod 11 also includes a conductive column 1161 and a connecting line 1162. One end of the conductive column 1161 is abutted and connected to the abutting section 1132, or is abutted and connected to the transmission member 113. The other end of the conductive column 1161 is fixed and passes through the fixed plate 115, and is electrically connected to the two poles of the battery 112 through a connecting line 1162 respectively.

[0760] It can be understood that the electric energy inside the battery 112 is transmitted to the corresponding connecting wires 1162 via the two poles, and then transmitted to the heating element 13 via the connecting wires 1162, the conductive column 1161 and the transmission element 113 in sequence, thereby realizing the atomization function of the cigarette rod assembly 10 of the present application.

[0761] In one embodiment, as shown in Figures 59-61, the cigarette holder 11 further includes a sensor 1171, and the bottom cover 114 is also provided with a sensing hole 1141. The sensing hole 1141 connects the outside air to the air inlet passage 31. The sensor 1171 is fixedly connected to the bottom cover 114 and covers the sensing hole 1141. One end of the sensor 1171 is electrically connected to a terminal of the battery 112, and the other end is electrically connected to a connecting wire 1162.

[0762] When external air enters the air inlet channel 31 through the air inlet hole 1112, some air also enters the air inlet channel 31 through the sensing air hole 1141. This air can trigger the sensor 1171 to connect the battery 112, the terminal, and the connecting wire 1162, thereby realizing current transmission between the battery 112 and the heating element 13, and realizing the atomization function of the cigarette rod assembly 10 of the present application.

[0763] When external air does not enter the air inlet passage 31 through the sensing air holes 1141, the sensor 1171 disconnects the electrical connection between the battery 112 and the connecting wire 1162. It is understood that the cigarette holder assembly 10 of the present application can utilize the user's puffing action to switch the current between the battery 112 and the heating element 13, thereby controlling the heat generation of the heating element 13, thereby improving the user experience.

[0764] In one embodiment, as shown in Figures 59-61, the cigarette holder 11 further includes a buffer 1172, which is placed between the battery 112 and the bottom cover 114, and the sensor 1171 is fixed to the buffer 1172. The buffer 1172 is provided with an air hole (not shown) to connect the air inlet channel 31 and the air inlet hole 1112.

[0765] It can be understood that the setting of the buffer member 1172 not only meets the airflow delivery at the opposite ends of the cigarette rod assembly 10 of the present application, but also cooperates with the bottom cover 114 to protect the battery 112 and the sensor 1171, reducing the impact of external forces on the battery 112 and the sensor 1171, and ensuring the atomization function of the cigarette rod assembly 10 of the present application.

[0766] In one embodiment, as shown in Figures 59 to 61, the cigarette rod 11 also includes a second seal 118, which is fixed to the surface of the fixing plate 115 facing the first opening 1111 to prevent the released aerosol from condensing and leaking into the battery 112 through the gap between the fixing plate 115 and the second shell 111, thereby avoiding the influence of the condensed aerosol matrix on the battery 112 and ensuring the use of the electronic cigarette 100 of the present application.

[0767] Please refer to FIG. 68 for a schematic structural diagram of a cigarette cartridge 20 provided in one embodiment of the present application.

[0768] As shown in Figure 68, the first housing 211 is provided with an oil storage tank 22. The oil storage tank 22 is used to store aerosol substrate. A liquid outlet 222 is provided on the partition 221, connecting the oil storage tank 22 with the external environment. When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled, the aerosol substrate stored in the oil storage tank 22 is released into the atomization chamber 33.

[0769] Specifically, the cigarette cartridge 20 further includes a liquid guide 23 , which includes a first end 23 a and a second end 23 b , wherein the first end 23 a is close to the inside of the first shell 211 , and the second end 23 b is located outside the first shell 211 .

[0770] As shown in Figure 68, when the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled into one body, the second end 23b can extend into the second housing 111 through the first opening 1111 and abut against the support member 12. This allows the heat from the heating element 13 to be transferred to the liquid-guiding member 23 and heat the liquid-guiding member 23. It is understood that in another embodiment, the support member 12 can also be spaced apart from the second end 23b of the liquid-guiding member 23.

[0771] As shown in Figure 68, the liquid guide member 23 has a porous structure, and the porous structure is connected between the first end 23a and the second end 23b. The porous structure within the first end 23a of the liquid guide member 23 can absorb the aerosol matrix within the oil storage tank 22. This portion of the aerosol matrix can infiltrate the side wall of the liquid guide member 23 through the porous structure. The second end 23b of the liquid guide member 23 can absorb the heat released by the heater 13 within the cigarette rod assembly 10 and atomize the aerosol matrix to form an aerosol.

[0772] Because the liquid-guiding member 23 and the support member 12 are in close contact with each other, and the sidewalls of the liquid-guiding member 23 extend beyond the first housing 211, it is understood that the aerosol formed is primarily released from the sidewalls of the liquid-guiding member 23. As shown in Figures 69 and 70, the aerosol matrix released from the sidewalls of the liquid-guiding member 23 can mix with the air entering from the air inlet passage 31 within the atomization chamber 33, forming a mixed gas that is released into the air outlet passage 32.

[0773] Therefore, the electronic cigarette 100 of the present application disposes the second end 23b of the liquid-guiding member 23 outside the first housing 211, so that the aerosol matrix in the liquid-guiding member 23 can be released from the side wall of the liquid-guiding member 23 under the action of the heating member 13. Because the contact between the liquid-guiding member 23 and the support member 12 reduces the space of the atomization chamber 33, the external air flows to the side wall of the liquid-guiding member 23 due to the pressure difference. It can be understood that the aerosol released from the side wall of the liquid-guiding member 23 and the inflowing air will directly contact and mix, thereby further improving the mixing quality of the aerosol and air in the electronic cigarette 100 of the present application and enhancing the user experience.

[0774] In one embodiment, both the liquid-conducting member 23 and the support member 12 are made of porous materials, and the porosity of the liquid-conducting member 23 is greater than that of the support member 12. Since the porosity is related to the liquid absorption and permeability of the material, the greater the porosity of the material, the greater the number of closed pores, the smaller the pore diameter, the stronger the liquid absorption and permeability of the material.

[0775] Since more aerosol matrix enters the liquid-guiding member 23 than the supporting member 12, it is understandable that the provision of the liquid-guiding member 23 with a relatively high porosity enables the aerosol matrix released from the liquid outlet 222 to be absorbed relatively quickly, thereby preventing the aerosol matrix from accumulating between the liquid outlet 222 and the liquid-guiding member 23, thereby causing the aerosol matrix to seep out between the liquid-guiding member 23 and the second housing 111.

[0776] At the same time, since the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-guiding member 23 can also diffuse into the entire liquid-guiding member 23 more quickly, thereby achieving a match between the heat released by the heating member 13 and the support member 12 and the capacity of the aerosol matrix guided toward the heating member 13, thereby ensuring the amount of aerosol released by the electronic cigarette 100 of the present application.

[0777] When some aerosol matrix overflows onto the surface of the support member 12, the porosity of the support member 12 is smaller than that of the liquid-conducting member 23. The aerosol matrix overflowing onto the surface of the support member 12, while being absorbed by the absorption support member, has a relatively slow penetration rate. Because the temperature decreases with increasing distance from the heating element 13, the amount of heat absorbed by the aerosol matrix also decreases accordingly. It is understandable that providing a support member 12 with a smaller porosity can reduce the penetration rate of the aerosol matrix, thereby extending the penetration time of the aerosol matrix, allowing the aerosol matrix to absorb more heat to atomize and form an aerosol.

[0778] That is, the matching setting of the porosity of the support member 12 and the liquid-conducting member 23 increases the amount of heat absorbed by the aerosol matrix from the heating member 13, thereby increasing the amount of aerosol generated by the electronic cigarette 100 of the present application and improving the user experience of using the electronic cigarette 100 of the present application.

[0779] In one embodiment, as shown in FIG68 , the liquid outlet 222 is blocked by a liquid guide 23, and the aerosol matrix stored in the oil storage tank 22 can contact the liquid guide 23 through the liquid outlet 222. The liquid guide 23 has a porous structure. It is understood that the liquid guide 23 can precipitate the aerosol matrix in the oil storage tank 22 out of the oil storage tank 22 and guide it away from the oil storage tank 22.

[0780] As shown in Figure 68, during the use of the electronic cigarette 100 of the present application, it is necessary to ensure that the content of the aerosol released from the electronic cigarette 100 during use is relatively consistent to ensure the user experience. The aerosol content released is related to the content of the aerosol matrix released and atomized by the cigarette cartridge 20. Due to the fluidity of the aerosol matrix, when the cigarette cartridge 20 is in different postures, the content of the aerosol matrix entering the liquid outlet 222 is relatively limited.

[0781] Therefore, a liquid guide 23 having a porous structure is provided, and is positioned on the oil storage bin 22 and blocks the liquid outlet hole 222, so that the liquid guide 23 can precipitate the aerosol matrix in the oil storage bin 22, thereby avoiding the impact of the cigarette cartridge 20 on the aerosol matrix release rate caused by the change in the posture of the cigarette cartridge 20. This ensures the aerosol release rate of the cigarette cartridge 20 and improves the aerosol matrix release effect of the electronic cigarette 100 of the present application.

[0782] At the same time, the liquid guide 23 also has a certain liquid storage function, and the liquid guide 23's release of aerosol matrix does not stop regardless of whether the electronic cigarette 100 is in use. When the user uses the electronic cigarette 100, the aerosol matrix stored in the liquid guide 23 can be atomized into aerosol as the user inhales. This improves the efficiency of the electronic cigarette 100's release of aerosol matrix and enhances the user experience.

[0783] In one embodiment, as shown in FIG68 , the cigarette cartridge 20 further includes a partition 221, which is fixed within the first housing 211 and cooperates with the first housing 211 to form the oil storage bin 22. A liquid outlet 222 is provided on the partition 221. The liquid guide 23 is attached to the surface of the partition 221 away from the inner side of the oil storage bin 22 and shields the liquid outlet 222 to facilitate the precipitation of the aerosol matrix within the oil storage bin 22. It is understood that the aerosol matrix stored in the oil storage bin 22 can pass through the partition 221 via the liquid outlet 222 and be precipitated by the liquid guide 23.

[0784] In another embodiment, as shown in FIG69 , the liquid guide 23 is fixed within the first housing 211 and cooperates with the first housing 211 to form an oil storage bin 22. The aerosol matrix directly contacts the surface of the liquid guide 23, and the aerosol matrix can be directly precipitated by the liquid guide 23 and guided in a direction away from the oil storage bin 22. It can be understood that the liquid guide 23 cooperates with the first housing 211 to form the oil storage bin 22, thereby increasing the contact area between the aerosol matrix and the liquid guide 23, improving the precipitation speed of the aerosol matrix by the cigarette cartridge 20 of the present application, and further improving the release effect of the aerosol matrix by the electronic cigarette 100 of the present application.

[0785] The liquid outlet holes 222 are provided on the liquid guide member 23. As the liquid guide member 23 has a porous structure, it is understandable that the pores distributed in the liquid guide member 23 are the liquid outlet holes 222.

[0786] In one embodiment, as shown in Figures 68 and 69, the second end 23b of the liquid-guiding member 23 is located outside the first shell 211, and along the first direction 001, the length of the second end 23b from the first shell 211 is between 0.5 mm and 2 mm. The length of the second end 23b outside the first shell 211 will affect the amount of aerosol released. It is understandable that when the distance between the second end 23b and the first shell 211 is less than 0.5 mm, there may be a situation where part of the aerosol formed by atomization cannot be released from the inside of the liquid-guiding member 23 to the outside, resulting in part of the aerosol coming into contact with the remaining aerosol matrix with a lower temperature and condensing into an aerosol matrix. This reduces the amount of aerosol released by the liquid-guiding member 23, reduces the proportion of aerosol in the gas inhaled by the user, and affects the user experience.

[0787] When the distance between the second end 23b and the first housing 211 is greater than 2 mm, some aerosol matrix may flow out from the side wall of the liquid guide 23 before being atomized in...
