Description

Technical Field

[0001] The present invention relates to the field of tobacco technology, and in particular to an aerosol generating device, a cigarette cartridge and an electronic cigarette. Background Art

[0002] As people pay more and more attention to health, they realize that traditional cigarettes are harmful to health. Therefore, products called electronic cigarettes have been produced. As a substitute for traditional cigarettes, electronic cigarettes are essentially an aerosol generating device that heats liquid substances containing nicotine. The electronic cigarette is equipped with a liquid storage part, an atomizing part and an aerosol channel. The atomizing part is a heating part for atomizing liquid substances, the liquid storage part is a part for storing liquid, and the aerosol channel is used to guide the aerosol generated by the atomizing part.

[0003] In the prior art, the liquid storage part is directly connected to the atomization part, the liquid in the liquid storage part is in direct contact with the atomization part, the atomization part heats the liquid to generate aerosol, and the aerosol is drawn out through the aerosol channel in the electronic cigarette and then inhaled by the user. This structure cannot realize the opening and closing of the liquid storage part, so that the liquid storage part is directly connected to the atomization part. When the external air pressure decreases, it is easy for the liquid in the liquid storage part to flow into the atomization part too much, and then leak into the aerosol channel, so that the smoking device is contaminated, which brings great inconvenience to the user.

[0004] In addition, the current method of atomizing e-liquid on the market is basically to use a heating wire to directly heat the oil guide rope soaked in e-liquid. The oil guide rope is always soaked in e-liquid. As the heat generation increases, the oil guide rate of the oil guide rope does not keep up, and the temperature of the heating wire assembly will rise. When the temperature reaches a certain level, the oil guide rope will deteriorate at high temperature, and the e-liquid will burn at high temperature, giving off a burnt smell. There is a risk of carbonization of the oil guide rope in the later stage of smoking, which in turn affects the oil supply of the oil guide rope and the smoking experience. In addition, the e-liquid keeps soaking the oil guide rope, and the atomization amount of the e-liquid cannot be controlled, affecting the consumer's smoking experience. Summary of the invention

In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0068] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0069] Embodiment 1:

[0070] refer to Figure 2 Combined with Figure 4 , Figure 8 As shown, the present invention provides an aerosol generating device 1, which includes a housing 10 having an inner cavity 11, a mouthpiece 20, a liquid storage portion 30 and an aerosol passage 22. The mouthpiece 20 is connected to the aerosol passage 22, and the aerosol can flow out of the aerosol passage 22 for the user to inhale. The mouthpiece 20 is disposed at one end of the housing 10, and the mouthpiece 20 extends along the extension direction of the inner cavity 11 ( Figure 8The liquid storage part 30 is provided with a push rod 25 and an insertion end 21 (shown in the X direction). The liquid storage part 30 has a liquid outlet 32, and the fluid in the liquid storage part 30 can flow out from the liquid outlet 32 ​​and flow to the atomization part 50. The aerosol generated by the atomization of the fluid by the atomization part 50 can flow into the aerosol channel 22 and flow out from the aerosol channel 22 for suction. In this embodiment, after the insertion end 21 of the mouth part 20 is inserted into the aerosol channel 22, the push rod 25 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32, thereby achieving synchronous closure of the aerosol channel 22 and the liquid outlet 32.

[0071] The aerosol generating device 1 of this embodiment has two states. Figure 3 , Figure 4 As shown, in the first state, the insertion end 21 of the mouth 20 is extended along the extension direction ( Figure 8 The push rod 25 abuts against the liquid outlet 32 ​​to close the aerosol passage 22, and the push rod 25 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32. At this time, the aerosol passage 22 of the aerosol generating device 1 is closed, and the atomizing part 50 will not be triggered to work. At the same time, the fluid in the liquid storage part 30 will not flow to the atomizing part 50, so that no aerosol will be generated. Figure 3 , Figure 4 Combined with Figure 5 In the second state, the insertion end 21 of the mouthpiece 20 is separated from the outer wall of the liquid storage part 30 along the extension direction to connect the aerosol passage 22, and the push rod 25 is separated from the liquid outlet 32 ​​to allow the fluid in the liquid storage part 30 to flow out from the liquid outlet 32. At this time, the aerosol passage 22 of the aerosol generating device 1 is connected, triggering the atomization part 50 to work, and at the same time, the fluid in the liquid storage part 30 flows to the atomization part 50, and the atomization part 50 atomizes the fluid to generate aerosol.

[0072] The aerosol generating device 1 in this embodiment is provided with a push rod 25, which abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32, and can effectively prevent the liquid in the liquid storage part 30 from leaking. In addition, the push rod 25 abuts against and separates from the liquid outlet 32 ​​to control the liquid spray of the electronic cigarette 6, and the atomization amount of the fluid is controlled, so that the user can inhale more safely and conveniently, and has a better inhalation experience.

[0073] It should be noted that the push rod 25 of the present invention is not limited to the way in which the liquid outlet 32 ​​abuts against each other, as long as the fluid in the liquid storage portion 30 can be prevented from flowing out of the liquid outlet 32 ​​after the push rod 25 abuts against the liquid outlet 32. Figure 5 Combined with Figure 3 , Figure 4As shown, in this embodiment, the push rod 25 has an insertion portion 26, which can be inserted into the liquid outlet 32 ​​and abut against the liquid outlet 32 ​​in the radial direction. The liquid outlet 32 ​​is a body of equal cross section, and the outer diameter of the insertion portion 26 gradually increases in the direction from the liquid outlet 32 ​​to the push rod 25, and the inner diameter of the liquid outlet 32 ​​is between the minimum outer diameter and the maximum outer diameter of the insertion portion 26, for example, it can be a sealed cavity 320 that can fit tightly with the insertion portion 26. With this design, the insertion portion 26 of the push rod 25 can be partially inserted into the liquid outlet 32 ​​and abut against the liquid outlet 32 ​​in the radial direction, thereby sealing the liquid outlet 32 ​​and preventing the fluid from flowing out of the liquid outlet 32.

[0074] See also Figure 7 Combined with Figure 4 , Figure 5 As shown, in other embodiments, the inserting portion 26 may be a boss structure, and the boss 260 of the inserting portion 26 is inserted into the liquid outlet 32 ​​and closely matches the liquid outlet 32, thereby also achieving sealing of the liquid outlet 32. In addition, if the boss 260 of the inserting portion 26 is connected to the push rod 25, the inserting portion 26 is closely in contact with the liquid outlet 32, thereby also achieving sealing and leakproof effects.

[0075] The connection method between the nozzle 20 and the push rod 25 of the present invention is not limited, as long as the nozzle 20 and the push rod 25 can be reliably connected. Figure 3 In this embodiment, the mouth 20 is provided with a clamping member 23, and the push rod 25 is provided with a clamping groove 250. The connection between the mouth 20 and the push rod 25 is achieved by clamping the clamping member 23 with the clamping groove 250. The structure is simple and the connection is reliable.

[0076] refer to Figure 3 Combined with Figure 5 As shown, in this embodiment, the portion of the liquid storage portion 30 facing the insertion end 21 is provided with a through hole 33, a sealing member 34 is provided in the through hole 33, and the push rod 25 passes through the sealing member 34 and is interference fit with the sealing member 34. During the pulling process, the fluid on the push rod 25 will be scraped off by the sealing member 34, thereby preventing oil leakage. The specific type of the sealing member 34 is not limited. In this embodiment, the sealing member 34 is a silicone plug.

[0077] In addition, reference Figure 2 Combined with Figure 4 As shown, the aerosol generating device 1 of the present invention further includes an atomizing unit 50, and the liquid outlet 32 ​​of the liquid storage unit 30 is arranged facing the atomizing unit 50. The specific type of the atomizing unit 50 is not limited, as long as the fluid flowing from the liquid outlet 32 ​​to the atomizing unit 50 can be atomized to generate aerosol.

[0078] Specifically, refer to Figure 6 Combined with Figure 4As shown, in this embodiment, the atomization part 50 includes an atomization housing 56, an electrode 55, a heating body 51 and an atomization chamber 52. The heating body 51 is used to heat the liquid derived from the liquid outlet 32. It is arranged on the atomization housing 56, located above the atomization chamber 52, corresponding to the liquid outlet 32. The atomization chamber 52 is used to store and output the aerosol generated by the atomization of the heating body 51. The electrode 55 is arranged on the atomization housing 56, located below the atomization chamber 52, and is electrically connected to the heating body 51 to provide electrical energy for the heating body 51. The heating body 51 is located below the liquid outlet 32. The liquid derived from the liquid outlet 32 ​​is atomized by the heating body 51 and then enters the aerosol channel 22 through the atomization chamber 52. The specific type of the heating body 51 is not limited, as long as it can atomize the fluid flowing from the liquid outlet 32 ​​to the atomization part 50 to produce aerosol. For example, the atomizing part 50 can be one of an electric heating wire, an infrared heating body, a microwave heating body, an electromagnetic conversion heating body and a porous ceramic heating body, or a glass fiber rope plus an electric heating wire structure or other types of heating structures. In this embodiment, the heating body 31 is a porous ceramic heating body, which has the characteristics of being able to absorb and store liquid, being resistant to high temperatures, being easy to clean and having a long service life.

[0079] Further, in this embodiment, referring to Figure 6 Combined with Figure 4 As shown, the atomizing chamber 52 includes an air inlet 53 and an aerosol outlet 54, and the aerosol outlet 54 is connected to the aerosol channel 22. The air inlet 53 and the aerosol outlet 54 are arranged on the atomizing housing 56. In the second state, air enters the atomizing chamber 30 from the air inlet 32, and after being fully mixed with the aerosol generated by the atomization of the heating body 31 in the atomizing chamber 30, enters the aerosol channel 22 from the aerosol outlet 33, enters the mouth 20 through the aerosol channel 22, and finally is inhaled by the user through the mouth 20. The arrangement of the air inlet 53 and the aerosol outlet 54 makes the aerosol movement smoother and more convenient for the user to inhale.

[0080] It should be noted that see Figure 4 Combined with Figure 5 As shown, the aerosol passage 22 is located on one side of the liquid storage part 30 and the atomization part 50, and is connected to the atomization chamber 52, which means that the aerosol passage 22 extends in the direction ( Figure 8 The heating body 51 is arranged on one side of the liquid storage part 30 and the atomization part 50, and is connected to the atomization chamber 52, and is used to guide the aerosol in the atomization chamber 52. In addition, the heating body 51 is located below the liquid outlet 32, and can be located directly below the liquid outlet 32, or can be located slightly below the liquid outlet 32, as long as it can ensure that the liquid guided out of the liquid outlet 32 ​​can be completely received by the heating body 51. In this embodiment, the heating body 51 is located directly below the liquid outlet 32, so that the heating body 51 can receive the guided liquid.

[0081] In this embodiment, see Figure 5 Combined with Figure 4 , Figure 3 As shown, the liquid storage part 30 also includes a liquid storage shell 31 and a liquid storage shell cover 35. The liquid storage shell 31 and the liquid storage shell cover 35 can be integrally formed or sealed and connected and assembled together. The inner cavity surrounded by the liquid storage shell 31 and the liquid storage shell cover 35 is a liquid storage cavity 300, which is used to store the liquid to be atomized. The liquid storage shell cover 35 is provided with a liquid outlet 32, and the liquid outlet 32 ​​is connected to the liquid storage cavity 300, and is used to guide the liquid in the liquid storage cavity 300. In this embodiment, the liquid storage shell 31 and the liquid storage shell cover 35 are connected together by assembly, and a sealing gasket 36 is provided between the liquid storage shell 31 and the liquid storage shell cover 35.

[0082] The above structure arranges the aerosol channel 22 on one side of the liquid storage part 30 and the atomization part 50, and communicates with the atomization chamber 52 of the atomization part 50, so that the aerosol flows out along the aerosol channel 22, and the aerosol can be more smoothly discharged during inhalation. At the same time, the contact area between the aerosol and the inner wall of the aerosol channel 22 is much smaller than the contact area between the aerosol and the inner wall of the shell 10 and the outer wall of the liquid storage part 30, so condensation is not easy to occur, so that users have a better use experience.

[0083] See also Figure 5 Combined with Figure 3 , Figure 4 As shown, in the present invention, the aerosol channel 22 includes a first aerosol channel 220 and a second aerosol channel 221. The first aerosol channel 220 is arranged at the aerosol outflow side of the atomizing part 50 along the extension direction of the inner cavity 11, and is communicated with the atomizing cavity 52. ​​The second aerosol channel 221 is arranged at one side of the liquid storage part 30 along the extension direction of the inner cavity 11, and penetrates the liquid storage part 30. The first aerosol channel 220 and the second aerosol channel 221 are communicated through a sealing tube 222. The aerosol channel 22 is divided into the first aerosol channel 220 and the second aerosol channel 221, and connected by the sealing tube 222, which is convenient for the design and installation of the aerosol channel 22, making the aerosol channel 22 structure more compact and easy to install.

[0084] Specifically, see Figure 5 Combined with Figure 3 , Figure 4As shown, in this embodiment, the first aerosol channel 220 is an air guide pipe, one end of the first aerosol channel 220 is inserted on the liquid storage shell cover 35, and the other end extends to the side of the aerosol outflow of the atomizing part 50, and is connected to the aerosol outlet 54 of the atomizing chamber 52, which is used to guide the aerosol in the atomizing chamber 52. The structure is simple and easy to install. The second aerosol channel 221 is arranged on one side of the liquid storage part 30 along the extension direction of the inner cavity 11, and penetrates the liquid storage part 30. The second aerosol channel 221 can be arranged inside the liquid storage part 30, located on one side of the liquid storage chamber 300, or can be arranged on one side outside the liquid storage part 30, close to the liquid storage part 30. In this embodiment, the second aerosol channel 221 is arranged in the liquid storage shell 31, located on one side of the liquid storage chamber 300, and penetrates the liquid storage shell 31 along the extension direction of the liquid storage shell 31. It is integrally formed with the liquid storage shell 31, which is convenient for processing and manufacturing, and has a compact structure. The first aerosol channel 220 is connected with the second aerosol channel 221 through a sealing tube 222. One end of the sealing tube 222 is inserted into the second aerosol channel 221, and the other end is inserted into the liquid storage shell cover 35, and is connected with the first aerosol channel 220. This can not only make the first aerosol channel 220 and the second aerosol channel 221 tightly connected to achieve gas sealing, but also prevent the liquid in the liquid storage chamber 300 from penetrating into the second aerosol channel 221, ensuring that the user has a better inhalation experience.

[0085] See also Figure 3 As shown, in this embodiment, the mouthpiece 20 is provided with a suction port 24. In the second state, the aerosol passes through the aerosol passage 22 and is sucked from the suction port 24.

The shell 10 and the mouth 20 are an integrated design, which can realize the synchronous movement of the shell 10 and the mouth 20, and is easy to operate. When the shell 10 is moved, the mouth 20 moves synchronously with the shell 10, and at the same time, the mouth 20 moves synchronously with the push rod 25, which can conveniently realize the conversion of the aerosol generating device 1 between the first state and the second state. In addition, the outside of the shell 10 is also provided with a twill 13 that increases the friction force, which is convenient for the user to push the shell 10 to move and is convenient to use.

[0088] Furthermore, in order to limit the moving distance of the housing 10, prevent the housing 10 from moving too far and causing damage to the push rod 25, and also to prevent the liquid storage part 30, the atomization part 50 and the aerosol passage 22 in the housing 10 from being exposed and contaminated, the present invention provides a limiting mechanism between the housing 10 and the liquid storage part 30.

In the first state, the push rod 25 is against the liquid outlet 32, and at this time, the limiting protrusion 37 is located at one end of the sliding groove 12. In the process of changing the first state to the second state, the housing 10 is pushed so that the limiting protrusion 37 and the sliding groove 12 move relative to each other, and the limiting protrusion 37 moves toward the other end of the sliding groove 12. When reaching the second state, the push rod 25 is separated from the liquid outlet 32, and the limiting protrusion 37 is located at the other end of the sliding groove 12. The combination of the sliding groove 12 on the housing 10 and the limiting protrusion 37 on the liquid storage part 30 limits the distance that the housing 10 moves along the extension direction, preventing the housing 10 from moving too long, and playing a role of limiting protection.

The specific type of the elastic element 40 is not limited. In this embodiment, the elastic element 40 is a spring, which is sleeved on the push rod 25 and located between the sealing member 34 and the insertion portion 26. When the push rod 25 is pulled from the outside, the elastic element 40 is compressed, and the push rod 25 is separated from the liquid outlet 32 ​​with the insertion portion 26, so that the liquid can flow out from the liquid outlet 32. When the external pulling force is eliminated, the elastic element 40 can drive the push rod 25 to restore the sealing state with the insertion portion 26. In addition, the elastic element 40 is provided on the push rod 25 between the insertion portion 26 and the sealing member 34, which can further compress the insertion portion 26, so that the insertion portion 26 remains in contact with the liquid outlet 32, so that the liquid outlet 32 ​​is more tightly sealed, and the effect of preventing liquid leakage is better achieved. In other embodiments, the elastic element 40 may also be located between the sealing member 34 and the mouth 20 to drive the inserting portion 26 to restore or maintain sealing with the liquid outlet 32 ​​.

[0090] It should be noted that see Figure 4 Combined with Figure 3 , Figure 5 As shown, in this embodiment, the cross-section of the aerosol channel 22 is circular, that is, the first aerosol channel 220, the second aerosol channel 221 and the sealing tube 222 are all tubular structures with circular cross-sections. The inner wall area of ​​the tubular structure is small, which is convenient for the flow of aerosol to pass through, the aerosol flows more smoothly, and the aerosol particles are not easy to condense, which can better meet the user's suction needs and improve the user's suction experience. In other embodiments, the cross-sectional shape of the aerosol channel 22 can also be other shapes, such as polygonal, half-moon, etc., as long as the smooth flow of aerosol can be guaranteed.

[0091] In the above-mentioned use process, the push rod 25 of the aerosol generating device 1 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32, which can effectively prevent the liquid in the liquid storage part 30 from leaking. In addition, the push rod 25 abuts against and separates from the liquid outlet 32 ​​to control the liquid spray of the electronic cigarette 6, and the atomization amount of the fluid is controlled, making the user's suction safer and more convenient, with a better suction experience. At the same time, by separately setting the aerosol channel 22 located on one side of the liquid storage chamber 300 and the atomization part 50, the aerosol can flow more smoothly and it is not easy for the aerosol particles to condense.

The mouthpiece 20 has an aerosol passage 22, and the aerosol can flow out from the aerosol passage 22 for the user to inhale. The mouthpiece 20 can be movably inserted into one end of the inner cavity 11 of the cartridge case 10, and the insertion end 21 of the mouthpiece 20 is provided with a longitudinal direction ( Fig. 9The liquid storage part 30 has a liquid outlet 32, and the fluid in the liquid storage part 30 can flow out from the liquid outlet 32 ​​and flow to the atomization part 50; the outer peripheral surface of the liquid storage part 30 and the inner cavity 11 have a radial gap A, and the aerosol generated by the atomization part 50 can flow into the aerosol channel 22 through the radial gap A along with the outside air, and flow out from the aerosol channel 22 for inhalation. In this embodiment, after the insertion end 21 of the cigarette holder 20 is inserted into the inner cavity 11 of the shell 10, the push rod 25 is inserted into the liquid storage part 30.

[0097] The cigarette cartridge 1 of this embodiment has two states. Fig. 9 In the first state, the insertion end 21 of the mouthpiece 20 and the outer wall of the liquid storage portion 30 are aligned along the extension direction ( Fig. 9 The push rod 25 abuts against the liquid outlet 32 ​​to close the aerosol channel 22, and the push rod 25 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32. At this time, the aerosol channel 22 of the cigarette cartridge 1 is closed, and the atomization part 50 will not be triggered to work. At the same time, the fluid in the liquid storage part 30 will not flow to the atomization part 50, so that no aerosol will be generated. Fig.10 In the second state, the insertion end 21 of the mouthpiece 20 is separated from the outer wall of the liquid storage part 30 along the extension direction to connect the aerosol channel 22, and the push rod 25 is separated from the liquid outlet 32 ​​to allow the fluid in the liquid storage part 30 to flow out from the liquid outlet 32. At this time, the aerosol channel 22 of the cigarette cartridge 1 is connected, triggering the atomization part 50 to work, and at the same time, the fluid in the liquid storage part 30 flows to the atomization part 50, and the atomization part 50 atomizes the fluid to generate aerosol. Fig.10 The dashed arrows represent the flow direction of the fluid, and the solid arrows represent the flow direction of the aerosol and the outside air.

[0098] The above structure realizes the liquid spray control of the electronic cigarette, the atomization amount of the fluid is controlled, and the consumer has a good smoking experience.

[0099] Continue to refer Fig. 9In this embodiment, the inner cavity 11 of the cartridge case 10 further includes: an elastic element 40, one end of the elastic element 40 is connected to the inner wall of the liquid storage part 30, and the other end is connected to the push rod 25. The specific type of the elastic element 40 is not limited. In this embodiment, the elastic element 40 is a spring, and the spring is sleeved on the push rod 25. When the user does not inhale, the mouthpiece 20 does not move, and the elastic force of the elastic element 40 drives the push rod 25 to resist the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32. When the user inhales, the mouthpiece 20 is pulled up, and the insertion end 21 of the mouthpiece 20 is separated from the outer wall of the liquid storage part 30 along the extension direction; thus, the push rod 25 will move synchronously with the mouthpiece 20, the elastic element 40 is compressed, and the push rod 25 is separated from the liquid outlet 32 ​​to allow the fluid in the liquid storage part 30 to flow out of the liquid outlet 32. After the user completes suction, the elastic force generated by the compression of the elastic element 40 drives the push rod 25 to automatically move toward the liquid outlet 32 ​​, so that the push rod 25 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage portion 30 from flowing out of the liquid outlet 32 ​​.

[0100] In other embodiments, reference Fig.11 , one end of the elastic element 40 is connected to the insertion end 21, and the other end is connected to the outer wall of the liquid storage part 30. The elastic element 40 is a tension spring. When the user does not inhale, the cigarette holder 20 does not move, and the elastic force of the elastic element 40 drives the push rod 25 to abut against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32. When the user inhales, the cigarette holder 20 is pulled up, and the insertion end 21 of the cigarette holder 20 is separated from the outer wall of the liquid storage part 30 along the extension direction. The push rod 25 will move synchronously with the cigarette holder 20, the elastic element 40 is stretched, and the push rod 25 is separated from the liquid outlet 32 ​​to allow the fluid in the liquid storage part 30 to flow out of the liquid outlet 32. After the user completes inhalation, the elastic force generated by the stretching of the elastic element 40 will drive the push rod 25 to automatically move toward the liquid outlet 32, so that the push rod 25 abuts against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32.

[0101] Continue to refer Fig. 9 In this embodiment, the mouthpiece 20 includes a clamping portion 23, which is arranged around the outer circumference of the cartridge case 10. There is a radial gap between the clamping portion 23 and the outer circumference of the cartridge case 10. The specific value of the radial gap is not limited. In this embodiment, the radial gap is 0.1mm to 0.5mm, including 0.1mm and 0.5mm, for example, it can be 0.3mm, 0.44mm or 0.48mm. The radial gap satisfies: After the clamping portion 23 is set, the clamping portion 23 can play a guiding role to prevent the push rod 25 from moving away from the extension direction.

[0102] When the push rod 25 separates from the liquid outlet 32 ​​along the extension direction and moves toward the liquid outlet 32 ​​again, the clamping portion 23 plays a guiding and limiting role to prevent the push rod 25 from moving away from the extension direction, so that the push rod 25 can accurately abut against the liquid outlet 32 ​​to prevent the fluid in the liquid storage portion 30 from flowing out of the liquid outlet 32 ​​and prevent leakage. Otherwise, when the push rod 25 moves toward the liquid outlet 32, it may deviate from the extension direction. Although it abuts against the liquid outlet 32, it will not completely seal the liquid outlet 32, and the fluid in the liquid storage portion 30 will flow out of the liquid outlet 32, resulting in leakage.

[0103] In addition, the clamping portion 23 can also be designed to be threadedly connected to the outer peripheral surface of the cartridge case 10, and the insertion end 21 of the mouthpiece 20 can be separated from the outer wall of the liquid storage portion 30 along the extension direction by screwing the clamping portion 23, while further playing a guiding and limiting role.

[0104] refer to Fig.12 In other embodiments, the cigarette holder 20 may not include the clamping portion 23, wherein there is a radial gap between the insertion end 21 and the inner circumference of the cartridge case 10, and the specific value of the radial gap is not limited. In this embodiment, the radial gap is 0.1mm to 0.5mm, including 0.1mm and 0.5mm, for example, it can be 0.3mm, 0.44mm or 0.48mm. The radial gap satisfies that the push rod 25 will not deviate from the extension direction and can stably move along the extension direction. The insertion end 21 can also be designed to be threadedly connected to the inner circumference of the cartridge case 10, and the insertion end 21 of the cigarette holder 20 is separated from the outer wall of the liquid storage portion 30 along the extension direction by screwing the insertion end 21, and it can also further play a guiding and limiting role.

In this way, the push rod 25 can stably move along the extension direction without deviating from the extension direction, so that the push rod 25 can accurately abut against the liquid outlet 32 ​​to prevent the fluid in the liquid storage part 30 from flowing out of the liquid outlet 32, thereby preventing oil leakage.

[0107] Continue to refer Fig. 9The clamping portion 23 of the present invention has a concave portion 24 that is concave inward in the radial direction and / or a convex portion that is convex outward in the radial direction, so that the user can pull the mouthpiece 20 more easily and control the upward or downward movement of the push rod 25.

In this embodiment, the sealing member 34 is a silicone plug.

[0110] In addition, reference Fig. 9 The cigarette cartridge 1 of the present invention further includes: an atomization unit 50, and the liquid outlet 32 ​​of the liquid storage unit 30 is arranged facing the atomization unit 50.
