Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to a cigarette rod assembly of an electronic cigarette, and an electronic cigarette comprising the cigarette cartridge. Background Art

[0002] In the prior art, an electronic cigarette generally includes a cartridge and a rod. The cartridge is provided with an atomizer assembly, and the rod is provided with a battery, which is connected to the heating element of the atomizer assembly. The cartridge also stores an aerosol matrix, which can be absorbed by the atomizer assembly and released as an aerosol under the action of the heating element. The released aerosol is mixed with air and then output from the mouthpiece of the cartridge.

[0003] In order to extend the service life of electronic cigarettes, a cigarette rod is usually matched with multiple cigarette cartridges. When the aerosol matrix in a single cigarette cartridge is consumed, a new cigarette cartridge can be replaced for continued use. However, in the prior art, since an atomizer component is provided in the cigarette cartridge, the atomizer component will also be wasted when the cigarette cartridge is discarded, thereby increasing the cost of using electronic cigarettes for users.

[0102] See also Figure 1 A schematic structural diagram of an electronic cigarette 100 provided in one embodiment of the present application is shown.

[0103] like Figure 1 As shown, the electronic cigarette 100 of the present application includes a cigarette rod assembly 10 and a cigarette cartridge 20, wherein the cigarette cartridge 20 includes a first shell 211, and an oil storage tank 22 is provided in the first shell 211, and an aerosol matrix is ​​stored in the oil storage tank 22. The cigarette rod assembly 10 includes a second shell 111, and a first opening 1111 is provided on the second shell 111. The cigarette cartridge 20 can partially extend into the first shell 211 through the first opening 1111.

[0104] The electronic cigarette 100 of the present application further includes an air circuit 30, which is connected to 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 before entering 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.

[0105] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the second shell 111 extends into the first inner cavity 21a of the first shell 211, and an atomization cavity 33 is formed between the cigarette cartridge 20 and the cigarette rod assembly 10. The air inlet channel 31 is located in the second shell 111, and the air outlet channel 32 is located in the first shell 211. The air inlet channel 31 is connected between the air inlet hole 1112 and the atomization cavity 33, and the air outlet channel 32 is connected between the air outlet hole 2121 and the atomization cavity 33.

[0106] It is understandable that when the user inhales the electronic cigarette 100 of the present application through the air outlet 2121 of the cigarette cartridge 20, the 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 will flow toward the heating element 13 of the cigarette rod assembly 10, and absorb the heat generated by the heating element 13 to be atomized into aerosol. The aerosol will mix with the external air, and enter the user's mouth from the air outlet 2121 along the air outlet channel 32 as the user inhales, thereby realizing the suction function of the electronic cigarette 100 of the present application.

[0107] For details, please refer to Figure 2 The structural diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown in FIG. Figure 3 The cross-sectional structure diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown in FIG. Figure 1 In the subsequent figures, the arrangement direction of the cigarette cartridge 20 and the cigarette rod assembly 10 is set to a first direction 001 , and a second direction 002 perpendicular to the first direction 001 is set. Figure 3 In order to facilitate the expression of Figure 2 and Figure 3 , a third direction 003 perpendicular to the first direction 001 and the second direction 002 is set.

[0108] like Figure 2 and Figure 3 As shown, 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 accommodated in the second shell 111. The support member 12 can be made of 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 various directions.

[0109] The heating element 13 is also housed in the second housing 111 and is disposed on the support 12. When the heating element 13 releases heat to the outside, the temperature of the support 12 increases. It can be understood that the heat released by the heating element 13 is transmitted to the aerosol matrix via the support 12, and the aerosol matrix is ​​atomized into an aerosol and released to the atomization chamber 33. Thus, the atomization function of the cigarette rod assembly 10 of the present application is realized.

[0110] like Figure 1-Figure 3 As shown, 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 can 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 shell 111 along the first direction 001, and flow to the liquid absorption surface 121, and be absorbed by the liquid absorption surface 121.

[0111] See also Figure 4 The partial structural diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown in FIG. Figure 5 The partial cross-sectional diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown in FIG. Figure 1 .

[0112] like Figure 1 , Figure 4 and Figure 5 As shown, the heating element 13 is disposed on the liquid absorption surface 121 of the support element 12 and partially exposes the liquid absorption surface 121 , so that the aerosol matrix flowing in from the first opening 1111 can contact the liquid absorption surface 121 and be absorbed by the support element 12 .

[0113] 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 into the second shell 111 from the first opening 1111. Among them, part of the aerosol matrix directly absorbs the heat released by the heating element 13 and is atomized into aerosol and released, and the other part of the aerosol matrix is ​​absorbed by the support member 12, and the part of the aerosol matrix is ​​atomized into aerosol and released under the action of the heat of the heating element 13. Thereby, the atomization function of the cigarette rod assembly 10 of the present application is realized.

[0114] 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 is at least partially arranged in 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.

[0115] In one embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the heating element 13 is annular, and the annular heating element 13 allows the heating element 13 to fit the surface of the support element 12 close to the side wall of the support element 12 .

[0116] 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 faster to form an aerosol and released outward from the side wall.

[0117] like Figure 1 As shown, 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 the air is flowed as the user inhales, and the 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 flow 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 the aerosol and the air, thereby improving the mixing quality of the aerosol and the air, and improving the user's taste.

[0118] That is, the aerosol released from the side wall of the support member 12 and the inflowing air will directly contact and mix. It can be understood that the provision of the annular heating element 13 can enable the aerosol formed by atomization to be released from the side wall of the support member 12, thereby improving the mixing quality of the aerosol and air of the cigarette rod assembly 10 of the present application and improving the user experience.

[0119] 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 understandable that when the range is less than 0.8 mm, the heat release range of the heating element 13 to the support member 12 will be reduced, and when the heat is transferred to the support member 12, the heat will also be transferred to other areas not covered by the heating element 13, resulting in a relatively low temperature of the side wall of the support member 12, thereby affecting the atomization effect.

[0120] When the range is greater than 1.5 mm, the radius of the inner circle will be reduced, thereby reducing the amount of aerosol substrate absorbed by the support member 12 and reducing the gap between the heater 13 and the push rod 15. The amount of aerosol substrate absorbed by the support member 12 has an upper limit. It can be understood that when the aerosol substrate is collected in the smaller gap between the heater 13 and the push rod 15, the aerosol substrate will cause the heater 13 and the push rod 15 to conduct, which may affect the use of the heater 13.

[0121] That is, the radius difference between the outer circle and the inner circle of the annular heating element 13 is set between 0.8mm and 1.5mm, which can ensure the heating function of the heating element 13 while avoiding the heating effect of the side wall of the support member 12 being affected due to the small heating area, thereby affecting the atomization effect of the cigarette rod assembly 10 of the present application.

[0122] In one embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the cigarette rod 11 includes a battery 112, and the battery 112 is used to be 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 arranged on the side of the support member 12 away from the battery 112 (such as Figure 5 upper surface shown).

[0123] 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.

[0124] In one embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the support member 12 is provided with two through holes 122 that penetrate and are spaced apart from each other. Each transmission member 113 includes a conductive segment 1131 and a supporting segment 1132. Among them, 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.

[0125] 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 element 113 , but also support the support element 12 , thereby ensuring the relative position of the heating element 13 .

[0126] 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.

[0127] See also Figure 6 Another partial structural diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown, and please refer to Figure 7Another partial cross-sectional schematic diagram of a cigarette rod assembly 10 provided in one embodiment of the present application is shown in FIG. Figure 1 .

[0128] like Figure 1 , Figure 6 and Figure 7 As shown, along the second direction 002, two mutually spaced grooves 123 are provided on the side wall of the support member 12, one end of each transmission member 113 is respectively 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.

[0129] It can be understood that the groove 123 is provided on the side wall of the support member 12, so that the transmission member 113 can pass through the support member 12 to realize the electrical connection between the battery 112 and the heating member 13 on opposite sides of the support member 12, and at the same time, the difficulty of processing the support member 12 is reduced. At the same time, the transmission member 113 can extend along the second direction 002 in the direction away from the support member 12, so as to ensure the electrical connection between the battery 112 and the transmission member 113, and at the same time, it can also support the support member 12, thereby ensuring the relative position of the heating member 13.

[0130] See also Figure 8 Another partial structural diagram of the cigarette rod assembly 10 provided in one embodiment of the present application is shown, and please refer to Fig. 9 FIG. 1 is another partial cross-sectional schematic diagram of a cigarette rod assembly 10 provided in one embodiment of the present application. Figure 1 .

[0131] like Figure 1 , Figure 8 and Fig. 9 As shown, the heating element 13 is fixed to the surface of the support member 12 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 will enter the second shell 111 from the first opening 1111. Wherein, the support member 12 also has a higher temperature under the heating of the heating element 13.

[0132] It can be understood that part of the aerosol matrix will be atomized into aerosol under the action 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, and this part of the aerosol matrix will be atomized into aerosol and released under the action of the heat of the heating member 13. Thus, the atomization function of the cigarette rod assembly 10 of the present application is realized.

[0133] On the other hand, since the cross-sectional area of ​​the heating element 13 is smaller than the cross-sectional area 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.

[0134] 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 that the battery 112 is electrically connected to the heating element 13 .

[0135] In one embodiment, the heating element 13 is made of metal.

[0136] In one embodiment, the heating element 13 is a conductive material layer.

[0137] In one embodiment, the support member 12 is made of ceramic.

[0138] 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 of the present application and improving the user experience.

[0139] In one embodiment, please refer to Figure 1-Figure 3 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 11 a.

[0140] 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. That is, the gap between the battery 112 and the bottom cover 114, and the gap between the battery 112 and the second housing 111 cooperate to form the air intake channel 31.

[0141] The air inlet hole 1112 is disposed on the bottom cover 114 . It is understandable that the 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 .

[0142] In one embodiment, if Figure 1-Figure 3 As shown, the cigarette rod 11 further includes a fixing plate 115, which is located between the battery 112 and the support member 12. The fixing plate 115 is provided with a connecting hole 1151, so that the air entering from the air inlet hole 1112 can be output from the connecting hole 1151 via the air inlet channel 31.

[0143] In one embodiment, the cigarette rod assembly 10 further includes a positioning rod 14. 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 the fixing plate 115 and is fixed on the fixing plate 115, thereby realizing the positioning of the support member 12 and the heating member 13.

[0144] In one embodiment, if Figure 1-Figure 3 As shown, 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 with the supporting section 1132, or abutted and connected with the transmission member 113. The other end of the conductive column 1161 is fixed and passes through the fixing plate 115, and is electrically connected to the two poles of the battery 112 through a connecting line 1162 respectively.

[0145] 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.

[0146] In one embodiment, if Figure 1-Figure 3 As shown, the cigarette rod 11 further includes a sensor 1171, and a sensing air hole 1141 is further provided on the bottom cover 114. The sensing air hole 1141 is connected between the external air and the air inlet channel 31. The sensor 1171 is fixedly connected to the bottom cover 114 and covers the sensing air hole 1141. One end of the sensor 1171 is electrically connected to a pole of the battery 112, and the other end is electrically connected to a connecting line 1162.

[0147] 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 part of air can trigger the sensor 1171 to connect the battery 112, the pole and the connecting wire 1162, thereby realizing the 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.

[0148] When the external air does not enter the air inlet channel 31 through the sensing air hole 1141, the sensor 1171 disconnects the electrical connection between the battery 112 and the connecting line 1162. It can be understood that the cigarette rod assembly 10 of the present application can use the user's puffing action to realize the current on and off between the battery 112 and the heating element 13, thereby realizing the heat generation control of the heating element 13, thereby improving the user's experience.

[0149] In one embodiment, if Figure 1-Figure 3As shown, the cigarette rod 11 further includes a buffer 1172, which is filled between the battery 112 and the bottom cover 114, and the sensor 1171 is fixed on the buffer 1172. The buffer 1172 is provided with an air hole (not shown in the figure) to connect the air inlet channel 31 and the air inlet hole 1112.

[0150] It can be understood that the setting of the buffer member 1172 not only satisfies the airflow transmission 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, reduces the impact of external force on the battery 112 and the sensor 1171, and ensures the atomization function of the cigarette rod assembly 10 of the present application.

[0151] In one embodiment, if Figure 1-Figure 3 As shown, 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.

[0152] See also Fig.10 The structure diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown.

[0153] like Fig.10 As shown, an oil storage bin 22 is provided in the first housing 211. The oil storage bin 22 is used to store aerosol matrix. A liquid outlet 222 is provided on the partition 221, and the liquid outlet 222 is connected to the oil storage bin 22 and the external environment. When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the aerosol matrix stored in the oil storage bin 22 of the cigarette cartridge 20 is released to the atomization chamber 33.

[0154] Specifically, the cigarette cartridge 20 further includes a liquid guide 23 , and the liquid guide 23 includes a first end 23a and a second end 23b opposite to each other, wherein the first end 23a is close to the inside of the first shell 211 , and the second end 23b is located outside the first shell 211 .

[0155] like Fig.10 As shown, when the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the second end 23b can extend into the second housing 111 through the first opening 1111 and fit with the support member 12. Thus, the heat of the heating member 13 can be transferred to the liquid guide member 23 and heat the liquid guide member 23. It can be understood that in another embodiment, the support member 12 can also be spaced apart from the second end 23b of the liquid guide member 23.

[0156] like Fig.10As shown, 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 inside the first end 23a of the liquid guide member 23 can absorb the aerosol matrix in the oil storage tank 22, and the part 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 heating element 13 in the cigarette rod assembly 10, and atomize the aerosol matrix to form an aerosol.

[0157] Based on the fact that the liquid guiding member 23 and the supporting member 12 are attached to each other, and the side wall of the liquid guiding member 23 extends out of the first shell 211, it can be understood that the formed aerosol is mainly released from the side wall of the liquid guiding member 23. Fig.11 and Fig.12 As shown, the aerosol matrix released from the side wall of the liquid guide 23 can be mixed with the air entering from the air inlet channel 31 in the atomization chamber 33 to form a mixed gas which is released into the air outlet channel 32 .

[0158] Therefore, the electronic cigarette 100 of the present application sets the second end 23b of the liquid guide 23 outside the first shell 211 so that the aerosol matrix in the liquid guide 23 can be released from the side wall of the liquid guide 23 under the action of the heating element 13. Since the fit between the liquid guide 23 and the support 12 reduces the space of the atomization chamber 33, the external air will flow to the side wall of the liquid guide 23 under the action of the air pressure difference. It can be understood that the aerosol released from the side wall of the liquid guide 23 and the inflowing air will directly contact and mix, thereby further improving the mixing quality of the aerosol and air of the electronic cigarette 100 of the present application and improving the user experience.

[0159] In one embodiment, the liquid guide 23 and the support 12 are both made of porous materials, and the porosity of the liquid guide 23 is greater than the porosity of the support 12. Since the porosity is related to the liquid absorption capacity and permeability of the material, the greater the porosity of the material, the greater the number of corresponding closed pores, the smaller the diameter of the pores, the stronger the liquid absorption capacity of the material, and the stronger the permeability.

[0160] The aerosol matrix entering the liquid guide member 23 is more than that entering the support member 12. It can be understood that the liquid guide member 23 with a higher porosity can make the aerosol matrix released from the liquid outlet 222 be absorbed relatively quickly, avoiding the aerosol matrix from accumulating between the liquid outlet 222 and the liquid guide member 23, thereby causing the aerosol matrix to seep out between the liquid guide member 23 and the second shell 111.

[0161] At the same time, based on the fact that the higher the porosity, the stronger the permeability of the corresponding material, the aerosol matrix absorbed by the liquid-conducting member 23 can also diffuse into the entire liquid-conducting member 23 more quickly, thereby achieving a match between the heat released by the heating member 13 and the supporting 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.

[0162] When part of the aerosol matrix overflows to the surface of the support member 12, the porosity of the support member 12 is smaller than that of the liquid guide member 23. The aerosol matrix overflowing to the surface of the support member 12 is absorbed by the absorption support member, and its penetration speed is relatively slow. Because the temperature decreases with the increase of the distance from the heating member 13, the heat absorbed by the aerosol matrix will also decrease accordingly. It can be understood that providing a support member 12 with a smaller porosity can reduce the penetration speed 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.

[0163] That is, the matching setting of the porosity of the support member 12 and the liquid-conducting member 23 increases the absorption of the heat generated by the heating member 13 by the aerosol matrix, 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.

[0164] In one embodiment, if Fig.10 As shown, the liquid outlet 222 is blocked by the liquid guide 23, and the aerosol matrix stored in the oil storage bin 22 can contact the liquid guide 23 through the liquid outlet 22. The liquid guide 23 has a porous structure. It can be understood that the liquid guide 23 can precipitate the aerosol matrix in the oil storage bin 22 out of the oil storage bin 22 and guide it in a direction away from the oil storage bin 22.

[0165] like Fig.10 As shown, during the use of the electronic cigarette 100 of the present application, it is necessary to ensure that the content of the aerosol released during the use of the electronic cigarette 100 is relatively consistent to ensure the user's experience. The aerosol release content is related to the content of the aerosol matrix released and atomized by the cartridge 20. Based on the fluidity of the aerosol matrix, when the cartridge 20 is in different postures, the content of the aerosol matrix entering the liquid outlet 222 is relatively limited.

[0166] Therefore, a liquid guide 23 with a porous structure is provided, and the liquid guide 23 is provided on the oil storage bin 22 and the liquid outlet hole 222 is blocked, so that the liquid guide 23 can precipitate the aerosol matrix in the oil storage bin 22, thereby avoiding the influence of the cigarette cartridge 20 on the release rate of the aerosol matrix caused by the change of the posture of the cigarette cartridge 20. In addition, the release amount of the aerosol of the cigarette cartridge 20 is guaranteed, and the release effect of the electronic cigarette 100 of the present application on the aerosol matrix is ​​improved.

[0167] At the same time, the liquid guide 23 also has a certain liquid storage function, and the liquid guide 23 will not stop releasing the aerosol matrix regardless of whether the electronic cigarette 100 is used. When the user uses the electronic cigarette 100, the aerosol matrix stored in the liquid guide 23 can be atomized into an aerosol as the user inhales. This improves the release efficiency of the electronic cigarette 100 of the present application for the aerosol matrix and improves the user's experience.

[0168] In one embodiment, if Fig.10 As shown, the cigarette cartridge 20 further includes a partition 221, which is fixed in the first shell 211 and cooperates with the first shell 211 to form an 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 in the oil storage bin 22. It can be understood that the aerosol matrix stored in the oil storage bin 22 can be precipitated by the liquid guide 23 through the liquid outlet 222 and the partition 221.

[0169] In another embodiment, if Fig.11 As shown, the liquid guide 23 is fixed in the first shell 211, and cooperates with the first shell 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 shell 211 to form the oil storage bin 22, which increases the contact area between the aerosol matrix and the liquid guide 23, improves the precipitation speed of the aerosol matrix of the cigarette cartridge 20 of the present application, and further improves the release effect of the electronic cigarette 100 of the present application on the aerosol matrix.

[0170] The liquid outlet holes 222 are arranged on the liquid guide member 23. Since the liquid guide member 23 has a porous structure, it can be understood that the pores distributed in the liquid guide member 23 are the liquid outlet holes 222.

[0171] In one embodiment, if Fig.10 and Fig.11As shown, 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 0.5mm and 2mm. 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 0.5mm, 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 contacting 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.

[0172] When the distance between the second end 23b and the first shell 211 is greater than 2 mm, part of the aerosol matrix may flow out from the side wall of the liquid guide 23 before being atomized into aerosol, thereby 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 use experience.

[0173] Therefore, the present invention limits the distance between the second end 23b and the first shell 211 to between 0.5mm and 2mm, which can prevent the aerosol matrix from leaking from the side wall of the liquid-conducting member 23 while ensuring the amount of aerosol released from the side wall of the liquid-conducting member 23, thereby ensuring the user experience.

[0174] In one embodiment, the first end 23a of the liquid guide 23 is spaced apart from the partition 221 along the first direction 001, and in the first direction 001, the projection of the first end 23a on the partition 221 accommodates the liquid outlet hole 222, thereby ensuring that the aerosol matrix flowing out of the liquid outlet hole 222 can flow to the first end 23a and be absorbed by the first end 23a.

[0175] In one embodiment, the liquid guiding member 23 is made of cotton, sponge or ceramic.

[0176] See also Fig.12 Another structural schematic diagram of the electronic cigarette 100 provided in one embodiment of the present application is shown in FIG. Fig.13 Another structural schematic diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown, and please refer to Fig.14 The figure shows an exploded schematic diagram of a cigarette cartridge 20 provided in one embodiment of the present application.

[0177] like Figure 12-14As shown, the cigarette rod assembly 10 further includes a push rod 15, which passes through the heating element 13 and leaves a gap between the push rod 15 and the heating element 13, so that the aerosol matrix can flow to the liquid absorption surface 121 through the gap. The cigarette cartridge 20 further includes a sealing plug 241, which is located in the oil storage bin 22, and one end of the sealing plug 241 is elastically connected to the first shell 211, and the other end covers the liquid outlet 222 to seal the oil storage bin 22.

[0178] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the push rod 15 passes through the liquid outlet hole 222 to push open the sealing plug 241 to release the aerosol matrix, thereby realizing the release function of the electronic cigarette 100 of the present application on the aerosol matrix.

[0179] In one embodiment, the push rod 15 and the support member 12 are made of the same material and are integrally formed.

[0180] In one embodiment, the push rod 15 and the positioning rod 14 are integrally formed.

[0181] In one embodiment, if Figure 12-14 As shown, the cigarette cartridge 20 further includes a connecting member 242, which is made of elastic material. It is understandable that the elastic force of the connecting member 242 can act on the sealing plug 241, so that the sealing plug 241 moves toward the liquid outlet 222, and the sealing plug 241 covers the liquid outlet 222, thereby sealing the oil storage bin 22.

[0182] like Fig.12 As shown, when the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the push rod 15 can extend into the liquid outlet 222 and push the sealing plug 241, and can also make the connecting member 242 deviate along the second direction 002, thereby releasing the aerosol matrix. It can be understood that in other embodiments, the connecting member 242 can also be displaced in other directions.

[0183] It can be understood that the connector 242 made of elastic material can not only ensure the sealing of the oil storage bin 22, but also cooperate with the push rod 15 to realize the release of the aerosol matrix. At the same time, when the push rod 15 is withdrawn, the elastic force of the connector 242 can also make the sealing plug 241 continue to cover the liquid outlet hole 222, thereby ensuring the sealing of the oil storage bin 22.

[0184] See also Fig.15 Another structural schematic diagram of the electronic cigarette 100 provided in one embodiment of the present application is shown.

[0185] like Fig.15As shown, the connecting member 242 is configured as a compression spring, one end of the connecting member 242 is fixed to the inner wall of the oil storage tank 22 away from the liquid outlet hole 222, and the other end is abutted against the sealing plug 241. It can be understood that the elastic force in the connecting member 242 can drive the sealing plug 241 to move along the first direction 001 toward the direction away from the connecting member 242, so as to cover the liquid outlet hole 222, thereby sealing the oil storage tank 22.

[0186] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the push rod 15 extends into the liquid outlet hole 222 and abuts against the sealing plug 241. The push rod 15 can push the sealing plug 241 to move along the first direction 001 away from the liquid outlet hole 222, thereby compressing the connecting piece 242 to open the liquid outlet hole 222 and release the aerosol matrix in the oil storage tank 22.

[0187] When the cigarette cartridge 20 and the cigarette rod assembly 10 are disconnected, the push rod 15 withdraws from the liquid outlet 222, and the elastic force stored in the connecting member 242 drives the sealing plug 241 to move along the first direction 001 toward the liquid outlet 222, until the sealing plug 241 covers the liquid outlet 222, thereby sealing the oil storage bin 22.

[0188] On the other hand, Fig.16 As shown, the connecting member 242 can also be configured as a tension spring, one end of the connecting member 242 is fixed to the periphery of the liquid outlet hole 222, and the other end is fixedly connected to the sealing plug 241. It can be understood that the elastic force in the connecting member 242 can drive the sealing plug 241 to extend into the interior of the connecting member 242 along the first direction 001 to achieve shielding of the liquid outlet hole 222, thereby achieving sealing of the oil storage tank 22.

[0189] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the push rod 15 extends into the liquid outlet hole 222 and abuts against the sealing plug 241. The push rod 15 can push the sealing plug 241 to move along the first direction 001 away from the liquid outlet hole 222, thereby stretching the connecting piece 242 to open the liquid outlet hole 222 and release the aerosol matrix in the oil storage tank 22.

[0190] When the cigarette cartridge 20 and the cigarette rod assembly 10 are disconnected, the push rod 15 withdraws from the liquid outlet 222, and the elastic force stored in the connecting member 242 drives the sealing plug 241 to move along the first direction 001 toward the liquid outlet 222, until the sealing plug 241 covers the liquid outlet 222, thereby sealing the oil storage bin 22.

[0191] In one embodiment, if Fig.15 As shown, the cigarette cartridge 20 further includes a sealing plate 243. The sealing plate 243 is received in the first shell 211 and fixed in the first shell 211. The sealing plate 243 cooperates with the first shell 211 to form the oil storage bin 22.

[0192] like Fig.15 As shown, the connecting member 242 is a compression spring, and along the first direction 001 , one end of the connecting member 242 is fixed to the sealing plate 243 , and the other end is abutted against the sealing plug 241 so that the sealing plug 241 has a tendency to block the liquid outlet 222 .

[0193] See also Fig.17 The cross-sectional structure diagram of the electronic cigarette 100 provided in one embodiment of the present application is shown.

[0194] like Fig.17 As shown, the cigarette cartridge 20 of the present application further includes a connecting member 242, a sealing plug 241 and a sealing plate 243. The sealing plate 243 is fixed to the first shell 211, the connecting member 242 and the sealing plug 241 are both accommodated in the oil storage bin 22, one end of the connecting member 242 is fixed to the sealing plate 243, and the second end extends toward the liquid outlet 222 and is fixedly connected to the sealing plug 241.

[0195] The sealing plate 243 is made of elastic material. It is understandable that when the cigarette cartridge 20 and the cigarette rod assembly 10 are not connected, the elastic force of the sealing plate 243 is transmitted to the sealing plug 241 through the connecting piece 242, so that the sealing plug 241 moves along the first direction 001 toward the liquid outlet 222 and blocks the liquid outlet 222, thereby realizing the sealing function of the cigarette cartridge 20 on the oil storage bin 22.

[0196] In one embodiment, if Fig.17 As shown, the sum of the lengths of the connecting member 242 and the sealing plug 241 is greater than the spacing between the sealing plate 243 and the partition plate 221. It can be understood that when one end of the connecting member 242 is installed with the sealing plug 241, it extends into the oil storage bin 22 and the other end of the connecting member 242 is fixed with the sealing plate 243, the connecting member 242 causes the sealing plate 243 to produce elastic deformation to ensure that the connecting member 242 and the sealing plug 241 can be accommodated in the oil storage bin 22.

[0197] When the connecting member 242 is connected between the sealing plug 241 and the sealing plate 243 , the elastic force inside the elastically deformed sealing plate 243 can act on the connecting member 242 , and the connecting member 242 pushes the sealing plug 241 into the liquid outlet 222 to achieve sealing of the oil storage tank 22 .

[0198] It can be understood that in one embodiment, when the sealing plug 241 extends into the liquid outlet 222 and covers the liquid outlet 222, the elastic deformation of the sealing plate 243 disappears, thereby increasing the service life of the sealing plate 243 while ensuring the sealing of the oil storage tank 22 by the sealing plug 241.

[0199] In another embodiment, when the sealing plug 241 extends into the liquid outlet hole 222 and covers the liquid outlet hole 222, the elastic deformation of the sealing plate 243 may still exist, so that the sealing plate 243 can continue to apply an elastic force to the sealing plug 241 along the first direction 001 toward the liquid outlet hole 222, further improving the sealing effect of the cigarette cartridge 20 of the present application on the aerosol matrix.

[0200] When the cigarette cartridge 20 and the cigarette rod assembly 10 are assembled as one, the push rod 15 can extend into the liquid outlet 222 and push the sealing plug 241, and make the connecting member 242 move along the first direction 001, so that the sealing plate 243 is elastically deformed along the first direction 001, thereby releasing the aerosol matrix.

[0201] It can be understood that the connector 242 made of elastic material can not only ensure the sealing of the oil storage bin 22, but also cooperate with the push rod 15 to realize the release of the aerosol matrix. At the same time, when the push rod 15 is withdrawn, the elastic force of the connector 242 can also make the sealing plug 241 continue to cover the liquid outlet hole 222, thereby ensuring the sealing of the oil storage bin 22.

[0202] See also Fig.18 Another exploded schematic diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown. Fig.17 .

[0203] like Fig.18 and Fig.17 As shown, the connecting member 242 has a first central axis L1, the sealing plate 243 has a second central axis L2, and the liquid outlet 222 has a third central axis L3. The first central axis L1, the second central axis L2 and the third central axis L3 overlap with each other.

[0204] It can be understood that when the first central axis L1 and the second central axis L2 coincide, the connecting member 242 abuts against the center position of the sealing plate 243. When the connecting member 242 squeezes the sealing plate 243 and causes the sealing plate 243 to produce elastic deformation, the force of the connecting member 242 on the sealing plate 243 will be evenly distributed around the sealing plate 243. At the same time, the connecting member 242 abuts against the center position of the sealing plate 243, and can also reduce the force of the connecting member 242 on the sealing plate 243 that is diffused between the sealing plate 243 and the first shell 211, thereby avoiding the influence of the connecting member 242 on the fixation between the sealing plate 243 and the first shell 211. The relative position of the sealing plate 243 and the first shell 211 is guaranteed.

[0205] When the first central axis L1 and the third central axis L3 coincide, the sealing plug 241 will directly extend into the liquid outlet 222 along the first direction 001, and the side wall of the sealing plug 241 will simultaneously abut against the hole wall of the liquid outlet 222. This avoids the situation where the sealing plug 241 squeezes the hole wall of the liquid outlet 222 and causes a gap between the sealing plug 241 and the liquid outlet 222. This further improves the sealing performance of the cigarette cartridge 20 of the present application for the aerosol matrix.

[0206] See also Fig.19 FIG. 2 is another structural diagram of a cigarette cartridge 20 provided in one embodiment of the present application. Fig.18 .

[0207] In one embodiment, if Fig.18 and Fig.19 As shown, the sealing plate 243 includes a supporting portion 2431 and a connecting portion 2432. A sealing opening 2111 is provided on one side of the first housing 211 away from the inner side of the oil storage tank 22, and the connecting portion 2432 is fixed to the sealing opening 2111 and covers the sealing opening 2111.

[0208] The connecting portion 2432 surrounds the outer periphery of the abutting portion 2431 and is connected to the abutting portion 2431. In the natural state, the thickness of the abutting portion 2431 of the sealing plate 243 is greater than the thickness of the connecting portion 2432.

[0209] After the abutting portion 2431 is installed on the connecting member 242, the abutting portion 2431 will be squeezed and deformed. Compared with the connecting portion 2432 that is farther away from the connecting member 242, the deformation amount of the abutting portion 2431 along the first direction 001 will be greater than the deformation amount of the connecting portion 2432. It can be understood that the abutting portion 2431 having a thickness greater than the thickness of the connecting portion 2432 can avoid the phenomenon that the abutting portion 2431 is broken due to the abutment of the connecting member 242 when the connecting member 242 causes the abutting portion 2431 to produce elastic deformation. The sealing function of the sealing plate 243 on the aerosol matrix is ​​guaranteed, thereby ensuring the sealing performance of the cigarette cartridge 20 of the present application.

[0210] In one embodiment, if Fig.19 As shown, a positioning hole 2433 is provided on the surface of the supporting portion 2431 facing the partition 221, and the connecting member 242 extends into the positioning hole 2433 and abuts against the bottom of the positioning hole 2433, so as to ensure the supporting effect of the connecting member 242 on the sealing plate 243 while preventing the connecting member 242 from shifting along the second direction 002 when the sealing plate 243 is deformed, thereby affecting the shielding function of the sealing plug 241 on the liquid outlet 222.

[0211] That is, the positioning hole 2433 is provided, and the connecting member 242 is extended into the positioning hole 2433, so as to prevent the connecting member 242 from being displaced along the second direction 002 when the sealing plate 243 is elastically deformed, thereby ensuring the elastic force on the sealing plate 243 acts on the sealing plug 241. The sealing performance of the cigarette cartridge 20 of the present application on the aerosol matrix is ​​further improved.

[0212] See also Fig. 20 The cross-sectional structure diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown.

[0213] like Fig. 20 As shown, the surface of the abutting portion 2431 facing the partition 221 is provided with a positioning protrusion 2434, and the positioning protrusion 2434 surrounds the end of the connecting member 242, preventing the connecting member 242 from being displaced along the second direction 002 when the sealing plate 243 is elastically deformed, thereby ensuring the elastic force on the sealing plate 243 acts on the sealing plug 241. The sealing performance of the cigarette cartridge 20 of the present application on the aerosol matrix is ​​further improved.

[0214] In one embodiment, the connecting member 242 is made of a rigid material.

[0215] In one embodiment, the connecting member 242 and the sealing plug 241 are integrally formed.

[0216] In one embodiment, the connecting member 242 and the sealing plate 243 are integrally formed.

[0217] In one embodiment, if Figure 21-23 As shown, a guide structure 222a is also provided on the first housing 211. The guide structure 222a is located at the end of the liquid outlet 222 facing the inner side of the oil storage tank 22. The guide structure 222a is conical, and includes a first guide port 2221 and a second guide port 2222 that are arranged opposite to each other. The first guide port 2221 is connected to the liquid outlet 222, and the aperture of the first guide port 2221 is smaller than the aperture of the second guide port 2222. That is, the end of the guide structure 222a with a larger cross section is far away from the liquid outlet 222, and the end with a smaller cross section is close to the liquid outlet 222.

[0218] When the cigarette cartridge 20 and the cigarette rod assembly 10 are disconnected, the sealing plug 241 can extend into the guide structure 222a under the elastic force of the sealing plate 243 and move toward the liquid outlet 222. It can be understood that the conical guide structure 222a can guide the sealing plug 241 to move toward the liquid outlet 222, and make the side wall of the sealing plug 241 abut against the conical inner wall of the guide structure 222a, thereby achieving sealing of the oil storage bin 22.

[0219] In one embodiment, if Figure 17-Figure 20As shown, the sealing plug 241 includes an abutment portion 2411, which is located on the side of the sealing plug 241 facing the liquid outlet 222. The abutment portion 2411 is conical, and the end of the conical abutment portion 2411 with a smaller cross-sectional area is close to the liquid outlet 222.

[0220] When the cigarette cartridge 20 is not connected to the cigarette rod assembly 10, the elastic force of the sealing plate 243 of the cigarette cartridge 20 pushes the sealing plug 241 to move toward the liquid outlet 222, and makes the abutment portion 2411 partially extend into the guide structure 222a. Among them, the tapered outer wall of the abutment portion 2411 extending into the guide structure 222a and the tapered inner wall of the guide structure 222a fit each other, thereby achieving the sealing of the oil storage bin 22 by the sealing plug 241. The sealing performance of the cigarette cartridge 20 of the present application to the aerosol matrix is ​​further improved.

[0221] It can be understood that in another embodiment, the guide structure 222a is a circular hole, the abutting portion 2411 of the sealing plug 241 is conical, and the abutting portion 2411 can at least partially extend into the guide structure 222a under the elastic force of the sealing plate 243 to seal the oil storage tank 22. In another embodiment, the guide structure 222a is conical, and the abutting portion 2411 of the sealing plug 241 is cylindrical. When the abutting portion 2411 extends into the guide structure 222a under the elastic force of the sealing plate 243, the conical inner wall of the guide structure 222a can guide the sealing plug 241 to extend into the guide structure 222a to seal the oil storage tank 22. In other embodiments, the shapes of the sealing plug 241 and the liquid outlet 222 can also be other, and the present application does not specifically limit this.

[0222] In one embodiment, the sealing plug 241 may be made of an elastic material, and the cone inclination angle of the guide structure 222a is smaller than the cone inclination angle of the abutment portion 2411 , and the abutment portion 2411 generates elastic deformation in the guide structure 222a to seal the oil storage tank 22 .

[0223] See also Fig.21 Another cross-sectional structural schematic diagram of an electronic cigarette 100 provided in one embodiment of the present application is shown.

[0224] like Fig.21 As shown, there is a gap between the side wall of the support member 12 and the inner wall of the second shell 111. Fig.21 As shown, when the cigarette cartridge 20 and the cigarette rod 11 are assembled as one, external air can flow from the atomization chamber 33 through the gap into the oil storage bin 22 located on the other side of the support member 12, thereby achieving a balance of air pressure on the opposite sides of the support member 12 and ensuring that the aerosol matrix flows from the oil storage bin 22 toward the support member 12.

[0225] In one embodiment, if Fig.21As shown, the support member 12 is provided with a first ventilation groove 124, wherein the first ventilation groove 124 penetrates the support member 12 along the first direction 001 to form a gap. The first ventilation groove 124 enables external air to communicate with the opposite sides of the support member 12, and prevents the aerosol matrix from leaking outward through the first ventilation groove 124. It can be understood that the first ventilation groove 124 is provided to prevent the leakage of the aerosol matrix while enabling the air on the opposite sides of the support member 12 to be conducted, so that the air pressure on the opposite sides of the support member 12 is relatively balanced, ensuring the flow smoothness of the aerosol matrix.

[0226] It is understandable that in this embodiment, the first ventilation groove 124 is disposed on the side wall of the support member 12 to form a gap. In other embodiments, the first ventilation groove 124 can also be disposed at other places of the support member 12 to form a gap, and this application does not specifically limit this.

[0227] In one embodiment, if Fig.21 As shown, along the first direction 001 , the support member 12 and the oil storage bin 22 are spaced apart, and the electronic cigarette 100 further includes a sealing member 25 , which surrounds the outer periphery of the push rod 15 and is located between the support member 12 and the oil storage bin 22 .

[0228] One end of the sealing member 25 is fixed on the partition 221, and the other end extends toward the support member 12. The sealing member 25 is also fixedly connected to the first shell 211. The sealing member 25 is used to prevent the aerosol matrix from overflowing from the gap between the support member 12 and the first shell 211.

[0229] In one embodiment, if Fig.21 As shown, a second ventilation groove 251 is provided on the side wall of the sealing member 25, wherein the second ventilation groove 251 is connected to the opposite sides of the support member 12 along the first direction 001, and the second ventilation groove 251 can allow the external air to communicate with the opposite sides of the support member 12, and prevent the aerosol matrix from leaking outward through the second ventilation groove 251. It can be understood that the second ventilation groove 251 is provided to prevent the leakage of the aerosol matrix, and can also make the air on the opposite sides of the support member 12 conduct, so that the air pressure on the opposite sides of the support member 12 is relatively balanced, and the flow smoothness of the aerosol matrix is ​​ensured.

[0230] In one embodiment, if Fig.21 As shown, the push rod 15 includes a third ventilation groove 151, the third ventilation groove 151 extends along the first direction 001, and one end of the third ventilation groove 151 is close to the oil storage tank 22. It can be understood that Fig.23As shown, the third ventilation groove 151 is connected to the inside and outside of the oil storage tank 22, so that external air can enter from one end of the third ventilation groove 151 through the first ventilation groove 124 and the second ventilation groove 251, and enter the oil storage tank 22 along the first direction 001, thereby balancing the air pressure between the oil storage tank 22 and the external environment.

[0231] In one embodiment, if Fig.21 As shown, the push rod 15 is set to be cylindrical, and the diameter of the push rod 15 is smaller than the diameter of the liquid outlet hole 222, so that when the push rod 15 extends into the liquid outlet hole 222, a gap can be formed between the push rod 15 and the liquid outlet hole 222 along the second direction 002 to connect the inside and outside of the oil storage tank 22. It can be understood that the external air can enter from the gap between the liquid outlet hole 222 and the push rod 15 through the first ventilation groove 124 and the second ventilation groove 251, and enter the oil storage tank 22 along the first direction 001, so as to balance the air pressure between the oil storage tank 22 and the external environment.

[0232] In one embodiment, if Figure 17-Figure 20 As shown, the cigarette cartridge 20 further includes a third shell 212. The first shell 211 is accommodated in the third shell 212. The third shell 212 is provided with an air outlet 2121, and the air outlet 2121 is located on a side of the third shell 212 away from the liquid outlet 222. The first shell 211 and the third shell 212 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 2121.

[0233] It can be understood that the mixed gas of aerosol and air enters the air outlet channel 32 from the first opening 1111, is transmitted to the air outlet hole 2121 along the first direction 001, and is output from the air outlet hole 2121. Thus, the user's inhalation function of the electronic cigarette 100 of the present application is realized.

[0234] See also Fig. 22 The partial structural diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown in FIG. Fig.23 The diagram shown is a partial cross-sectional diagram of a cigarette cartridge 20 provided in one embodiment of the present application.

[0235] like Fig. 22 and Fig.23 As shown, the cigarette cartridge 20 further includes a spacer 26. The third shell 212 is cylindrical, and a plurality of spacers 26 are provided, and the plurality of spacers 26 are arranged at intervals along the circumference of the third shell 212, and each spacer 26 is fixed between the first shell 211 and the third shell 212.

[0236] A gap is left between every two adjacent spacers 26 to form an air outlet channel 32. It can be understood that the mixed gas of aerosol and air entering from the first opening 1111 can be transmitted from between two adjacent spacers 26 to the air outlet hole 2121.

[0237] At the same time, the spacer 26 can support the first shell 211 while ensuring the gap between the first shell 211 and the third shell 212 , so as to fix the relative positions of the first shell 211 and the third shell 212 .

[0238] It is understandable that in other embodiments, the outer wall shape of the first shell 211 can also be other, and correspondingly, the spacer 26 can be arranged between the first shell 211 and the third shell 212 along the outer contour of the cigarette cartridge 20 along the second direction 002.

[0239] In one embodiment, if Fig. 22 and Fig.23 As shown, the cigarette cartridge 20 further includes a liquid absorbent 27, which is disposed between every two adjacent spacers 26 and is spaced apart from at least one spacer 26 to ensure that the mixed gas of aerosol and air entering from the first opening 1111 can be output. The liquid absorbent 27 can be used to absorb the aerosol matrix condensed during the transmission process to prevent the aerosol matrix from entering the mouth through the air outlet channel 32, thereby ensuring the user's use experience.

[0240] In one embodiment, if Fig. 22 and Fig.23 As shown, along the radial direction of the first shell 211, the thickness of the liquid absorbing member 27 is smaller than the spacing distance between the outer wall of the first shell 211 and the inner wall of the third shell 212. Fig. 22 As shown, the liquid absorbing member 27 is attached to the inner wall of the third shell 212. That is, the liquid absorbing member 27 is spaced apart from the first shell 211 to form an air outlet channel 32. It can be understood that aerosol and air can flow to the air outlet 2121 through the gap between the liquid absorbing member 27 and the first shell 211, thereby realizing the suction function of the electronic cigarette 100.

[0241] See also Fig.24 Another partial structural diagram of the cigarette cartridge 20 provided in one embodiment of the present application is shown, and please refer to Fig.25 Another partial cross-sectional schematic diagram of a cigarette cartridge 20 provided in one embodiment of the present application is shown.

[0242] like Fig.24 and Fig.25As shown, the circumference of the first shell 211, the liquid absorbent member 27 is spaced apart from an adjacent spacer 26. The liquid absorbent member 27 is fixed to the outer wall of the first shell 211 and the inner wall of the third shell 212, and the liquid absorbent member 27 is attached to one spacer 26 along the circumference of the first shell 211. That is, the liquid absorbent member 27 is spaced apart from another spacer 26 to form an air outlet channel 32. It can be understood that aerosol and air can flow to the air outlet 2121 through the gap between the liquid absorbent member 27 and another spacer 26, thereby realizing the suction function of the electronic cigarette 100.

[0243] In one embodiment, there are multiple liquid absorbent members 27, and the number of liquid absorbent members 27 is the same as the number of spacers 26. There is one liquid absorbent member 27 between each two adjacent spacers 26, so that when the aerosol is transmitted to the air outlet 2121 through each air outlet channel 32, the aerosol matrix formed by condensation can be absorbed by the liquid absorbent member 27, further improving the user experience.

[0244] It is understandable that in other embodiments, the number of the liquid absorbent members 27 may be less than the number of the spacers 26, and correspondingly, one liquid absorbent member 27 is filled between two adjacent spacers 26. This application does not specifically limit this.

[0245] In one embodiment, the absorbent member 27 is made of cotton, sponge or ceramic.

[0246] In one embodiment, the spacer 26 is made of metal or plastic.

[0247] In one embodiment, the spacer 26 and the third housing 212 are integrally formed.

[0248] In one embodiment, the spacer 26 may also extend in a spiral shape along the first direction 001. It is understandable that the spacer 26 extending in a spiral shape increases the overall length of the spacer 26, 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.
