[0038] See also Figure 1 A schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application is shown.

[0039] like Figure 1 As shown, 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, the cigarette rod 20 includes a second shell 21, and an oil storage tank 12 is provided in the first shell 111, and an aerosol matrix is ​​stored in the oil storage tank 12. The second shell 21 has a first opening 211, and the cartridge 10 can partially extend into the first shell 111 through the first opening 211.

[0040] Specifically, the electronic cigarette 100 of the present application further includes an air circuit 30, which is connected to two opposite sides of the electronic cigarette 100. When a user inhales from one side of the electronic cigarette 100, an air pressure difference is formed on the opposite sides of the electronic cigarette 100, so that external 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 inlet channel 31, an air outlet channel 32 and an atomization chamber 33.

[0041] When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the second shell 21 extends into the inner cavity 11a of the first shell 111, and an atomization chamber 33 is formed 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 is connected between the air inlet hole 2121 of the cigarette rod 20 and the atomization chamber 33, and the air outlet channel 32 is connected between the air outlet hole 1121 of the cigarette cartridge 10 and the atomization chamber 33.

[0042] It is understandable that when the user inhales the electronic cigarette 100 of the present application through the air outlet 1121 of the cigarette cartridge 10, the 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 shell 21 will flow toward the heating element 23 of the cigarette rod 20, and absorb the heat generated by the heating element 23 to be atomized into aerosol. The aerosol will mix with the external air, and enter the user's mouth from the air outlet 1121 along the air outlet channel 32 as the user inhales, thereby realizing the suction function of the electronic cigarette 100 of the present application.

[0043] For details, please refer to Figure 2 The structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown in FIG. Figure 3 The exploded schematic diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown in FIG. Figure 1 For the convenience of description, Figure 1 The arrangement direction of the cigarette cartridge 10 and the cigarette rod 20 is set to a first direction 001, and the second direction 002 is perpendicular to the first direction 001.

[0044] like Figure 1-Figure 3 As shown, the cigarette cartridge 10 of the present application further includes an oil storage bin 12, which is received in the first housing 111 and is used to store the aerosol matrix. The oil storage bin 12 is provided with a liquid outlet 121, which connects the oil storage bin 12 with the external environment, so that the aerosol matrix stored in the oil storage bin 12 can flow out of the oil storage bin 12 through the liquid outlet 121.

[0045] like Figure 1-Figure 3 As shown, 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 . The third shell 112 is further provided with an air outlet hole 1121 on one side away from the liquid outlet hole 121 , and the air outlet hole 1121 is connected to the air outlet channel 32 .

[0046] When the cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol matrix in the 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.

[0047] It can be understood that after the aerosol and the 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.

[0048] In the prior art, the air path in the electronic 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.

[0049] Therefore, compared with the prior art, the cigarette cartridge 10 of the present application is provided with an air outlet channel 32 between the first shell 111 and the third shell 112, and an air outlet hole 1121 is provided on the third shell 112, and the air outlet hole 1121 is connected with the air outlet channel 32. Thus, while ensuring the function of the cigarette cartridge 10 of the present application to transport aerosol and air, 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.

[0050] At the same time, the air outlet channel 32 is arranged at the periphery of the first housing 111, which also avoids the influence of the structure forming the air outlet channel 32 on the storage amount of the aerosol matrix. On the other hand, since the aerosol matrix stored in the first housing 111 is liquid, in the prior art, when the air outlet channel 32 is located in the oil storage bin 12, the aerosol matrix will absorb the heat of the aerosol, thereby increasing the possibility of aerosol condensation.

[0051] That is, by arranging the air outlet channel 32 at the periphery of the oil storage bin 12, it is also possible to reduce the absorption of heat of the aerosol by the aerosol matrix, thereby ensuring the content of the aerosol released by the cigarette cartridge 10 through the air outlet hole 1121 of the present application, thereby further improving the user experience.

[0052] In one embodiment, if Figure 1-Figure 3 As shown, a second opening 1122 is further provided on one side of the third housing 112 away from the air outlet 1121. Figure 2 As shown, along the first direction 001 , a cavity is left between the first shell 111 and the third shell 112 . The cavity is connected to the external environment through the second opening 1122 .

[0053] When the cartridge 10 and the cigarette rod 20 are assembled as one, the cartridge 10 extends into the second shell 21 through the first opening 211, and correspondingly, the second opening 1122 also extends into the second shell 21 along with the 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 an atomization chamber 33. That is, along the first direction 001, an atomization chamber 33 is provided between the first shell 111 and the third shell 112.

[0054] 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.

[0055] See also Figure 4 The partial structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown in FIG. Figure 5 The partial cross-sectional diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown in FIG. Figure 2 .

[0056] like Figure 2 , Figure 4 and Figure 5 As shown, 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. The communication between the second opening 1122 and the air outlet hole 1121 of the cigarette cartridge 10 of the present application is ensured.

[0057] At the same time, the support member 13 can also support the first housing 111. Figure 2 As shown, the first shell 111 is received in the third shell 112 , and the support member 13 can support the first shell 111 while ensuring a gap between the first shell 111 and the third shell 112 , so as to fix the relative positions of the first shell 111 and the third shell 112 .

[0058] In one embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, the outer wall of the first shell 111 is cylindrical, and the number of the support members 13 is multiple. Along the circumference of the first shell 111, the multiple support members 13 are arranged at intervals in the circumferential direction, so that two adjacent support members 13 can cooperate with the first shell 111 and the third shell 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 shell 111 and the third shell 112.

[0059] 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 at right angles to the assembly direction of the cigarette cartridge 10 and the cigarette rod 20.

[0060] When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the aerosol in the atomization chamber 33 can be dispersed by multiple air outlet channels 32 after mixing with the external air. It can be understood that the provision of multiple support members 13 blocks the transmission path of the aerosol and the air, thereby increasing the mixing time of the aerosol and the air, and increasing the mixing efficiency of the aerosol and the air, thereby improving the user's taste.

[0061] In one embodiment, if Figure 4 As shown, the plurality of support members 13 are evenly distributed around the circumference to improve the consistency of the mixing ratio of the mixed gas of aerosol and air flowing out of each gas outlet channel 32, thereby further improving the user's taste.

[0062] In one embodiment, if Figure 4 and Figure 5 As shown, the support member 13 is fixed to the inner wall of the third housing 112. It can be understood that in another embodiment, as Figure 6 As shown, the support member 13 may also be fixed on the outer wall of the first shell 111 .

[0063] In one embodiment, if Figure 4-Figure 6 As shown, the cigarette cartridge 10 of the present application further includes a liquid absorbent 14. The liquid absorbent 14 is made of a porous material and is filled between two adjacent support members 13. During the transportation of the aerosol, the heat of the aerosol may be absorbed by the aerosol matrix in the oil storage tank 12 and the external air. It can be understood that the setting of the liquid absorbent 14 allows the aerosol condensed into the aerosol matrix due to the reduction of heat to be absorbed, thereby avoiding the situation where the condensed aerosol matrix is ​​inhaled into the mouth of the user, thereby improving the user's experience.

[0064] In one embodiment, if Figure 4 and Figure 5 As shown, along the radial direction of the first shell 111, the thickness of the liquid absorbing member 14 is smaller than the spacing distance between the outer wall of the first shell 111 and the inner wall of the third shell 112. Figure 4 As shown, the liquid absorbing member 14 is attached to the inner wall of the third shell 112. That is, the liquid absorbing member 14 is spaced apart from the first shell 111 to form an air outlet channel 32. It can be understood that aerosol and air can flow to the air outlet 1121 through the gap between the liquid absorbing member 14 and the first shell 111, thereby realizing the suction function of the electronic cigarette 100.

[0065] In another embodiment, the liquid absorbent member 14 may also be attached to the outer wall of the first shell 111. Correspondingly, the liquid absorbent member 14 is spaced apart from the third shell 112 to form an air outlet channel 32. In another embodiment, the liquid absorbent member 14 may also be spaced apart from the first shell 111 and the third shell 112 along the radial direction of the first shell 111. Correspondingly, the gaps between the liquid absorbent member 14 and the first shell 111 and the third shell 112 may form an air outlet channel 32. This application does not specifically limit this.

[0066] See also Figure 7 Another partial structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown, and please refer to Figure 8 Another cross-sectional structural diagram of the cigarette cartridge 10 provided in one embodiment of the present application is shown in FIG. Figure 2 .

[0067] like Figure 2 , Figure 7 and Figure 8 As shown, along the circumference of the first shell 111, the liquid absorbent member 14 is spaced apart from an adjacent support member 13. The liquid absorbent member 14 is fixed to the outer wall of the first shell 111 and the inner wall of the third shell 112, and along the circumference of the first shell 111, the liquid absorbent member 14 is attached to one support member 13. That is, the liquid absorbent member 14 is spaced apart from another support member 13 to form an air outlet channel 32. It can be understood that aerosol and air can flow to the air outlet 1121 through the gap between the liquid absorbent member 14 and another support member 13, thereby realizing the suction function of the electronic cigarette 100.

[0068] It is understandable that in another embodiment, the liquid absorbing member 14 can also be spaced apart from two supporting members 13 at the same time. That is, two air outlet channels 32 are formed between two adjacent supporting members 13. This application does not make any special limitation to this.

[0069] In one embodiment, if Figure 1 and Figure 2 As shown, the liquid absorbing member 14 includes an extension section 141, which extends toward the second opening 1122 and extends into the atomization chamber 33. It can be understood that when the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the heating element 23 on the cigarette rod 20 and the aerosol matrix released by the cigarette cartridge 10, in conjunction with the aerosol formed by atomization, are transported toward the air outlet channel 32, and the liquid absorbing member 14 can also absorb the aerosol condensed in the atomization chamber 33. This further improves the user experience.

[0070] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 7, the number of the liquid absorbent members 14 is multiple, and the number of the liquid absorbent members 14 is the same as the number of the supporting members 13. Among them, there is a liquid absorbent member 14 filled between each two adjacent supporting members 13, so that when the aerosol is transmitted to the air outlet 1121 through each air outlet channel 32, the aerosol matrix formed by condensation can be absorbed by the liquid absorbent member 14. The user experience is further improved.

[0071] It can be understood that in other embodiments, such as Fig. 9 As shown, the number of the liquid absorbing members 14 may also be less than the number of the supporting members 13, and correspondingly, one liquid absorbing member 14 is filled between two adjacent supporting members 13. This application does not make any special limitation to this.

[0072] In one embodiment, the absorbent member 14 is made of cotton, sponge or ceramic.

[0073] In one embodiment, the support member 13 is made of metal or plastic.

[0074] In one embodiment, the support member 13 may also extend in a spiral shape along the first direction 001. It is understandable that 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, 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 improving the user's taste.

[0075] In one embodiment, if Figure 1 and Figure 2 As shown, the cigarette cartridge 10 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. It can be understood that the aerosol matrix stored in the oil storage bin 12 can flow out through the partition 122 via the liquid outlet 121.

[0076] like Figure 1 and Figure 2 As shown, a sealing opening 1111 is provided on one side of the first shell 111 away from the liquid outlet 121, and the cigarette cartridge 10 further includes a sealing plate 153, which is fixed to the sealing opening 1111 and covers the sealing opening 1111. The oil storage tank 12 is formed by the cooperation of the partition plate 122 and the first shell 111.

[0077] In one embodiment, if Figure 1 and Figure 2As shown, the cigarette cartridge 10 of the present application further includes a sealing plug 151 and a connecting piece 152. The sealing plug 151 and the connecting piece 152 are both received in the oil storage bin 12, one end of the connecting piece 152 is fixed on the sealing plate 153, and the other end extends toward the liquid outlet 121 and is fixedly connected to the sealing plug 151.

[0078] In one embodiment, if Figure 1 and Figure 2 As shown, the cigarette cartridge 10 further includes a sealing member 16, which surrounds the periphery of the partition 122 and extends in a direction away from the partition 122. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one body, as shown in FIG. Figure 1 As shown, the seal 16 is also located between the diffuser 22 of the cigarette rod 20 and the first shell 111. It is understandable 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 from the liquid outlet 121, it may flow to the side wall of the seal 16 due to the influence of the posture of the cigarette cartridge 10. It is understandable that the setting of the seal 16 allows this part of the aerosol matrix to flow toward the cigarette rod 20 under the guidance of the seal 16, thereby preventing the leakage of the aerosol matrix. The sealing performance of the cigarette cartridge 10 of the present application is improved.

[0079] See also Fig.10 The structural diagram of the cigarette rod 20 provided in one embodiment of the present application is shown in FIG. Fig.11 The cross-sectional structure diagram of the cigarette rod 20 provided in one embodiment of the present application is shown in FIG. Figure 1 .in, Fig.10 and Fig.11 This is a schematic diagram of the structure of the cigarette rod 20 in different directions. Fig.10 and Fig.11 A third direction 003 perpendicular to both the first direction 001 and the second direction 002 is set.

[0080] like Figure 1 , Fig.10 and Fig.11 As shown, the cigarette rod 20 of the present application further includes a diffuser 22 and a heating element 23. The diffuser 22 is made of a porous material. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the diffuser 22 can absorb the aerosol matrix flowing into the second shell 21 from the first opening 211 to prevent the aerosol matrix from flowing into the air path 30, thereby ensuring the user's experience.

[0081] The heating element 23 is fixed on the diffuser 22 to heat the diffuser 22, and atomize the aerosol matrix absorbed by the diffuser 22 into an aerosol, and release it to the atomization chamber 33, thereby preventing the aerosol matrix stored in the diffuser 22 from flowing out of the diffuser 22. At the same time, the heat of the heating element 23 can also atomize the aerosol matrix. Thus, the atomization function of the cigarette rod 20 of the present application on the aerosol matrix is ​​realized.

[0082] In one embodiment, if Figure 1 , Fig.10 and Fig.11 As shown, 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.

[0083] It can be understood that the aerosol matrix in the oil storage tank 12 can be directed to the diffuser 22 through the liquid outlet 121. Part of the aerosol matrix is ​​atomized into aerosol and released by the heat released by the diffuser 22 after being heated by the heating element 23, and another part of the aerosol matrix is ​​absorbed by the diffuser 22, and the aerosol matrix is ​​atomized into aerosol and released under the action of the heat of the heating element 23. Thus, the atomization function of the electronic cigarette 100 of the present application is realized.

[0084] 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 with the diffuser 22 and be absorbed by the diffuser 22 .

[0085] In one embodiment, if Figure 1 , Fig.10 and Fig.11 As shown, the cigarette rod 20 further includes a push rod 24, which is fixed to the surface of the diffuser 22 and extends in a direction 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 hole 121 and push the sealing plug 151 to move along the first direction 001 in a direction away from the liquid outlet hole 121, thereby opening the liquid outlet hole 121 and realizing the release of the aerosol matrix of the cigarette cartridge 10 by the cigarette rod 20.

[0086] like Figure 1 , Fig.10 and Fig.11 As shown, the second housing 21 further includes a bottom cover 212, which is fixed to one end of the second housing 21 away from the first opening 211 to form a second inner cavity 21a with the second housing 21. An air inlet 2121 is provided on the bottom cover 212. It can be understood that external air can enter the second housing 21 through the air inlet 2121 and mix with the aerosol formed by atomization from the heating element 23.

[0087] In one embodiment, the second housing 21 further includes a fixing plate 213, and the fixing plate 213 is located between the first opening 211 and the bottom cover 212 along the first direction 001. A connecting hole 2131 is provided on the fixing plate 213, and the connecting hole 2131 is connected to the air inlet 2121, so that the air entering from the air inlet 2121 can be discharged from the connecting hole 2131 and discharged outward from the first opening 211.

[0088] In one embodiment, if Figure 1 , Fig.10 and Fig.11 As shown, 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.

[0089] 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 is matched to form an air intake passage 31. It can be understood that external air can be transmitted to the first opening 211 through the air intake hole 2121 and the air intake passage 31.

[0090] 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 on the fixing plate 213 , thereby realizing the positioning of the diffuser 22 .

[0091] In one embodiment, if Fig.10 and Fig.11 As shown, the positioning rod 25 and the push rod 24 are an integrated structure.

[0092] In one embodiment, if Figure 1 , Fig.10 and Fig.11 As shown, the cigarette rod 20 further includes a conductive column 271 and a connecting line 272. One end of a conductive column 271 passes through the fixing plate 213 and is electrically connected to a pole of the battery 26 through a connecting line 272, and the other end extends toward the first opening 211. When the cigarette cartridge 10 and the cigarette rod 20 are assembled as one, the two conductive columns 271 are abutted against and conducted with the heating element 23, thereby realizing the electrical connection between the battery 26 and the heating element 23. Thus, the atomization function of the cigarette cartridge 10 is realized.

[0093] In one embodiment, if Fig.10 and Fig.11As shown, the cigarette rod 20 further includes a sensor 281, and a sensing air hole 2122 is further provided on the bottom cover 212. The sensing air hole 2122 is connected between the external air and the air inlet channel 31. The sensor 281 is fixedly connected to the bottom cover 212 and covers the sensing air hole 2122. One end of the sensor 281 is electrically connected to a pole of the battery 26, and the other end is electrically connected to a connecting line 272.

[0094] 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 part of air can trigger the sensor 281 to conduct the battery 26, the pole 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 electronic cigarette 100.

[0095] When the external air does not enter the air inlet channel 31 through the sensing air hole 2122, the sensor 281 disconnects the electrical connection between the battery 26 and the connecting line 272. It can be understood that the electronic cigarette 100 of the present application can use the user's puffing action to realize the current on and off between the battery 26 and the heating element 23, thereby realizing the heat generation control of the heating element 23. This improves the user's experience.

[0096] In one embodiment, if Fig.10 and Fig.11 As shown, the cigarette rod 20 further includes a buffer 282, which is filled between the battery 26 and the bottom cover 212, and the sensor 281 is fixed on the buffer 282. The buffer 282 is provided with an air hole (not shown in the figure) to connect the air inlet channel 31 and the air inlet hole 2121.

[0097] 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.

[0098] In one embodiment, if Fig.10 and Fig.11 As shown, 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.
