Description

Technical Field

[0001] The invention relates to the technical field of smoking articles, in particular to a cigarette cartridge and an electronic cigarette with a protruding atomizing core. Background Art

[0002] Electronic cigarettes are a new type of electronic product that looks similar to ordinary cigarettes and has the same taste as ordinary cigarettes. Since electronic cigarettes heat the oil through an atomizer to produce smoke that can be inhaled, compared with traditional cigarettes, electronic cigarettes do not burn, do not produce a variety of harmful chemicals after combustion, and do not cause harm to others and pollution to the environment due to "second-hand smoke", so electronic cigarettes are healthier and more environmentally friendly than traditional cigarettes.

[0003] The electronic cigarette includes two parts: a cigarette rod and a cigarette cartridge. The cigarette cartridge includes an atomizer, which atomizes the oil in the cigarette cartridge and burns it with air to form smoke. The smoke flows into the smoking port of the cigarette holder from the flue arranged in the cigarette cartridge for the user to inhale. In the prior art, the atomizer is arranged at the bottom of the oil tank, and a groove is formed on the atomizer. The oil in the oil tank first flows to the groove of the atomizer, and then the atomizer core of the atomizer heats the oil entering the atomizer to atomize the oil. However, with the atomizer core structure of the prior art, the oil in the oil tank must flow out of the oil tank to the groove of the atomizer located below the oil tank before it can be atomized. Since the oil in the oil tank usually cannot flow completely into the atomizer below it, even if there is oil in the oil tank, it cannot be guaranteed that the heating part of the atomizer core always stores oil. The atomizer core is very easy to heat up when there is no oil or insufficient oil, thereby causing dry burning and damage to the atomization. Summary of the invention

[0004] In view of this, the present invention provides a cigarette cartridge and an electronic cigarette with a raised atomization core, so as to solve the technical problem that the smoke oil in the existing electronic cigarette structure must flow into the atomization device below the oil tank to be atomized, and the contact area between the smoke oil and the atomization core is small.

[0016] Preferably, it also includes a conductive sheet, which is located inside the atomizer end cover and is formed integrally with the atomizer end cover. The conductive sheet is formed by extending from the inner wall of the atomizer end cover opposite to the atomizer device toward the atomizer device; the atomizer end cover forms an electrical connection between the electrode of the atomizer device located inside the atomizer end cover and the contact point in contact with the outer wall of the atomizer end cover through the conductive sheet.

[0017] Preferably, the atomizer end cover as a whole is a conductor, so that the contact in contact with the outer wall of the atomizer end cover and the electrode in contact with the conductive sheet inside the atomizer end cover form an electrical connection, and the atomizer end cover also includes a contact contact portion integrally formed with its outer wall, and the contact contact portion is formed by the outer wall of the atomizer end cover protruding in a direction opposite to the atomization device to a preset height position.

[0034] Embodiment 1:

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a cigarette cartridge 100 with a protruding atomization core. The cigarette cartridge 100 of this embodiment is used in conjunction with a cigarette rod 200 with a power supply. The power supply in the cigarette rod 200 provides electrical energy to the atomization device 30 of the cigarette cartridge 100. The atomization device 30 converts the electrical energy into heat to atomize the tobacco oil stored in the oil tank 10 of the cigarette cartridge 100. When the user inhales in the mouthpiece 20, negative pressure is formed at the cigarette oil outlet of the cigarette cartridge 100 and the atomization device 30. Under the action of negative pressure, air enters the cigarette cartridge 100 from the air inlet 52 of the cigarette cartridge 100, and brings the atomized tobacco oil to the inhalation port 21 of the mouthpiece 20 along the internal air flow channel of the cigarette cartridge 100 for the convenience of the user to inhale.

[0036] In this embodiment, a protrusion 321 is provided on the atomizer core 32, and the protrusion 321 extends all the way into the oil tank 10, so that the heat-generating part of the atomizer core 32 can always be immersed in the smoke oil, increasing the contact area between the smoke oil and the atomizer core, and improving the oil conduction rate, so that the heated part of the atomizer core 32 will not dry burn in the absence of smoke oil. In addition, since the atomizer core 32 is directly immersed in the smoke oil to heat the smoke oil in this embodiment, the heat can be gradually conducted and diffused in the smoke oil, so that the smoke oil in the oil tank 10 forms a good temperature gradient around the protrusion 321 of the atomizer core 32, so that the smoke oil atomization time can be shortened, and the smoke oil can be atomized more fully, and smoke with a better taste can be formed after mixing with air.

[0037] like Figure 2 and Figure 3 As shown, the cigarette cartridge 100 with a protruding atomizer core of this embodiment includes:

[0038] The oil tank 10 is used to store the smoke oil;

[0039] In this embodiment, the oil tank 10 is used as the oil storage component of the cigarette cartridge 100, and a receiving chamber for receiving the cigarette oil is formed in the oil tank 10. In specific implementation, part of the material in the oil tank 10 can be removed to form the receiving chamber, or the oil tank 10 with the receiving chamber can be manufactured by an integrated molding method. The opening of the receiving chamber is opened on the side facing away from the smoking port 21, and the cigarette oil is injected into the receiving chamber from the aforementioned opening when the cigarette cartridge 100 is produced.

[0040] A cigarette holder 20, fixed to the oil tank 10, is provided with a smoking opening 21;

[0041] In this embodiment, the mouthpiece 20 as a part of the shell of the cigarette cartridge 100 is sleeved on the outside of the oil tank 10 . When using, the user holds the mouthpiece 20 in his mouth and inhales, and the atomized smoke enters the user's mouth through the inhalation port 21 on the mouthpiece 20 .

[0042] an atomizing device 30, which is in communication with the chamber of the oil tank 10 for storing the tobacco oil and is used for atomizing the tobacco oil;

[0043] like Figure 4 and Figure 5 As shown, the atomization device includes an atomization core 32 for generating heat, and a protrusion 321 is formed on the atomization core 32. The protrusion 321 extends from a side of the atomization core 32 facing the oil tank 10 to the oil tank 10, so that the atomization core 32 heats the tobacco oil in the oil tank 10;

[0044] In this embodiment, the atomizer core 32 preferably has a good high temperature resistance. After the atomizer device is powered on, the atomizer core 32 converts electrical energy into heat energy to heat the smoke oil, so that the smoke oil is atomized, and after being fully mixed with the air entering the smoke cartridge 100, it enters the user's mouth through the smoking port of the cigarette holder for the user to inhale. In this embodiment, a protrusion 321 is set on the atomizer core 32, and the protrusion 321 part extends all the way to the oil tank 10, so that the heat-generating part of the atomizer core 32 can always be immersed in the smoke oil, so that the heated part of the atomizer core 32 will not dry burn in the absence of smoke oil, thereby causing the atomizer core 32 to be burned and damaged, and it is easy to cause the burnt material to enter the user's mouth with the smoke, seriously affecting the user experience. In addition, since the atomizer core 32 is directly immersed in the smoke oil to heat the smoke oil in this embodiment, the heat can be gradually conducted and diffused in the smoke oil, so that the smoke oil in the oil tank 10 forms a good temperature gradient around the protrusion 321 of the atomizer core 32, which can shorten the atomization time of the smoke oil and make the atomization of the smoke oil more complete, so that smoke with better taste can be formed after mixing with air.

[0045] In addition, the present embodiment further comprises a smoke duct, which guides smoke formed after the smoke oil is atomized by the atomization device 30 to flow toward the smoke outlet 21;

[0046] The oil tank base 40 is connected to the end of the oil tank 10 close to the atomizing device 30;

[0047] The oil tank base 40 is formed with an opening 43 for connecting the atomizing device 30 and the oil tank.

[0048] The oil tank base 40 is used to seal the oil tank 10 to prevent the smoke oil in the oil tank 10 from leaking out of the oil tank 10 .

[0049] like Figure 4 As shown, in this embodiment, the protrusion 321 of the atomizer core 32 passes through the opening 43 of the oil tank base 40 and extends to a position at a preset distance from the bottom of the oil tank 10, so that the protrusion 321 is partially or completely immersed in the smoke oil in the oil tank 10 to generate heat.

[0050] The bottom of the oil tank 10 refers to the end face of the oil tank 10 facing the atomizer. The rest of the atomizer core 32 except the protrusion 321 is located on the side of the opening 43 of the oil tank base 40 opposite to the oil tank 10. The protrusion 321 part passes through the opening 43 and enters the oil tank 10, so that the smoke oil can be heated without the smoke oil flowing through the opening 43, further avoiding the possibility of the smoke oil leaking from the oil tank base 40. The preset distance from the protrusion 321 to the bottom of the oil tank 10 can be designed according to the actual use situation, so that the protrusion 321 part can be well infiltrated into the oil tank 10 to heat the smoke oil.

[0051] An atomizing end cover 50 is provided on the side of the oil tank base 40 facing the atomizing device 30;

[0052] This embodiment further includes an atomizer fixing member 42 for fixing the position of the atomizer 30 in the cigarette cartridge 100. The atomizer fixing member 42 is formed integrally with the oil tank base 40 by in-mold injection molding.

[0053] In order to fully atomize the smoke oil, the atomizer 30 needs to be fixed to the bottom of the oil tank 10 in this embodiment. Therefore, the atomizer fixing member 42 is provided in this embodiment, and the atomizer 30 is fixed to the bottom of the oil tank 10 by the fixing member. Since the temperature of the atomizer 30 is relatively high during operation, the atomizer fixing member 42 of this embodiment can be made of a material that is resistant to high temperatures and has fast heat dissipation, and the atomizer fixing member 42 is formed integrally with the oil tank base 40 by in-mold injection molding.

[0054] Among them, in-mold injection molding is an existing integrated molding process. The atomizer fixture 42 and the oil tank base 40 are formed into an integrated in-mold injection molding structure through in-mold injection molding. The process of in-mold injection molding of the atomizer fixture 42 is to place the atomizer fixture 42 at a specific position in the mold, and then inject the injection material into the mold to finally form an integrated product of the atomizer fixture 42 and the oil tank base 40. After the high-temperature resistant material is used and the oil tank base 40 is integrated through in-mold injection molding, the atomizer 30 and the oil tank base 40 become an integral structure, and no additional assembly is required.

[0055] like Figure 6 As shown, although the atomizing device fixing part 42 and the oil tank base 40 are an integrated structure, after the in-mold injection molding process is adopted, the atomizing device fixing part 42 may not be made of the same material as the oil tank base 40, but may be made of a material that is resistant to high temperatures, has fast heat dissipation, and has high strength. In this way, the atomizing device 30 can be quickly cooled, and good structural stability can be maintained under long-term high temperature conditions, so that the atomizing device fixing part 42 can always reliably fix the atomizing device 30.

[0056] The atomizing device fixing part 42 is formed by 316 stainless steel surrounding the outer surface of the atomizing device 30 . The shape of the cross section formed by the atomizing device fixing part 42 surrounding the outer surface of the atomizing device 30 matches the shape of the cross section of the atomizing device 30 .

[0057] In this embodiment, the atomizing device 30 can be formed integrally with the oil tank base 40 by in-mold injection molding using 316 stainless steel material. The atomizing device fixing member 42 can be an annular structure, and the atomizing device 30 is inserted into the annular structure for fixing. In order to enable the atomizing device fixing member 42 to reliably fix the atomizing device 30, the cross-sectional shape of the area surrounded by the annular structure is designed in this embodiment to match the cross-sectional shape of the outer surface of the atomizing device 30. In this way, the inner wall of the atomizing device fixing member 42 can be tightly attached to the outer surface of the atomizing device 30 to fix the atomizing device 30, and the atomizing device 30 can quickly dissipate heat through the atomizing device fixing member 42.

[0058] The atomizing device 30 includes an atomizing core 32 and a coating layer 31 coated on the outer wall of the atomizing core 32. The atomizing device fixing part 42 is an annular enclosure extending from the end surface of the oil tank base 40 opposite to the oil tank 10 toward the atomizing end cover 50. The enclosure and the end surface of the oil tank base 40 opposite to the oil tank 10 together form a accommodating space for accommodating the atomizing device 30. The atomizing device 30 is located in the accommodating space, and the coating layer 31 fills the gap between the enclosure and the atomizing device 30.

[0059] When the atomizing device 30 is fixed to the oil tank base 40 , the elasticity of the covering layer 31 is utilized to allow the covering layer 31 to fully fill the gap between the enclosure and the atomizing device 30 , so that the atomizing device 30 can be reliably fixed to the oil tank base 40 .

[0060] In addition, in this embodiment, a conductive sheet 51 is further included, which is located inside the atomizing end cover 50 and is formed integrally with the atomizing end cover 50. The conductive sheet 51 is formed by extending from the inner wall of the atomizing end cover 50 opposite to the atomizing device 30 toward the atomizing device 30.

[0061] The conductive sheet 51 can be made of a metal with good conductive properties. Since the conductive sheet 51 is located inside the atomizing end cap 50, it can be manufactured by an integrated molding method of in-mold injection molding. In order to improve the conductivity of the conductive sheet 51, the magnitude of the current it conducts can be increased by increasing the cross-sectional area of ​​the conductive sheet 51. Since the conductive sheet 51 is located inside the atomizing end cap 50, it does not need to penetrate from the outside of the atomizing end cap 50 to the inside of the atomizing end cap 50, so it is not limited by size, and the cross-sectional area can be set according to the current conduction requirements, so that its cross-sectional area is larger than the corresponding preset area.

[0062] The atomizing end cover 50 forms an electrical connection between the electrode of the atomizing device 30 located inside the atomizing end cover 50 and the contact point in contact with the outer wall of the atomizing end cover 50 through the conductive sheet 51 .

[0063] like Figure 3 and Figure 6As shown, when the cigarette rod 200 and the cigarette cartridge 100 are assembled, the contact of the cigarette rod 200 contacts the outer wall of the atomizer end cover 50 on the outside of the cigarette cartridge 100, and the electrode of the atomizer device 30 located inside the atomizer end cover 50 contacts the conductive sheet 51. After power is turned on, the outer wall of the atomizer end cover 50 conducts the current to the inner wall of the atomizer end cover 50, and then the inner wall conducts the current to the conductive sheet 51 integrally formed with the inner wall, and finally the conductive sheet 51 conducts the current to the electrode of the atomizer device 30 in contact with the conductive sheet 51.

[0064] In order to form a reliable electrical connection between the electrode of the atomizing device 30 and the contact point in contact with the outer wall of the atomizing end cover 50, the atomizing end cover 50 of the present embodiment is a conductor as a whole, and the atomizing end cover 50 also includes a contact point contact portion 53 integrally formed with the outer wall thereof, and the contact point 53 is formed by the outer wall of the atomizing end cover 50 protruding in a direction opposite to the atomizing device 30 to a preset height position.

[0065] Since the atomizer end cap 50 is a conductor as a whole, the current can be conducted from any area outside the atomizer end cap 50 to any area of ​​the wall of the atomizer end cap 50 without the need for other components to penetrate the atomizer end cap 50 from the outside to the inside. And using the entire atomizer end cap 50 as a conductor can increase the amount of current that can be conducted at a cost compared to the pin needle of the prior art, so that the atomization effect of the atomizer device 30 is significantly improved. In order to make the contact of the cigarette rod 200 reliably contact the outer wall of the atomizer end cap 50. At least one raised portion facing the contact direction of the cigarette rod 200 is set at a position corresponding to the contact on the outer surface of the atomizer end cap 50 facing the cigarette rod 200 electrode, and the raised portion maintains a certain height difference with the outer surface of the atomizer end cap 50 facing the cigarette rod 200 electrode, so that the contact of the cigarette rod 200 can reliably contact the raised contact contact portion 53. In order to prevent the leakage of smoke oil from the atomizing end cover 50 , the contact protrusion is manufactured in an integrated manner with the atomizing end cover 50 , so that no gaps for assembling various components are formed in the atomizing end cover 50 .

[0066] Since the conductive sheet 51 does not need to penetrate the atomizing end cap 50 from the outside to the inside, the shape and size of the conductive sheet 51 are not easily restricted. At this time, the cross-sectional area of ​​the conductive sheet 51 can be increased as needed, for example, the cross-sectional area of ​​the conductive sheet 51 can be limited to be greater than a certain preset area value. In order for the conductive sheet 51 to be in reliable contact with the electrode of the atomizing device 30, the conductive sheet 51 needs to have a certain elasticity, and the shape and size of the conductive sheet 51 are not limited by other factors. Therefore, the conductive sheet 51 can be relatively flat, that is, the width of the conductive sheet 51 can be appropriately increased without reducing the cross-sectional area of ​​the conductive sheet 51, so that the ratio of the width to the thickness of the conductive sheet 51 is greater than a certain set value, so that the elasticity of the conductive sheet 51 can be increased, so that the conductive sheet 51 can be reliably in contact with the electrode of the atomizing device 30 by relying on the elastic restoring force.

[0067] like Figure 6 and Figure 7 As shown, in order to ensure reliable contact between the conductive sheet 51 and the electrode of the atomizing device 30, it is necessary to allow the conductive sheet 51 to be deformed to a large extent without being damaged. Therefore, the conductive sheet 51 of this embodiment is provided with a frustum-shaped reinforcement structure 511 at one end connected to the atomizing end cover 50, and the other end is a free end. The cross-sectional area of ​​the frustum gradually decreases from the atomizing end cover 50 toward the free end, and the ratio of the cross-sectional area of ​​the frustum at the junction of the frustum and the inner wall of the atomizing end cover 50 to the height of the frustum is less than the first threshold.

[0068] In the present embodiment, the end of the conductive sheet 51 that contacts the electrode of the atomizing device 30 is a free end that is not fixed to other components, so that the end of the conductive sheet 51 that contacts the electrode can be freely deformed according to the height of the electrode to adapt to electrodes in different positions. No matter how the height of the electrode changes, the conductive sheet 51 can be reliably in contact with the electrode by adaptively changing the position of the free end. Since the free end of the conductive sheet 51 needs to be pressed against the electrode, the root position where the conductive sheet 51 and the atomizing end cover 50 are connected is subjected to the largest bending moment, so a reinforcement structure 511 is provided there. The reinforcement structure 511 is in the shape of a cone, and the closer the reinforcement structure 511 is to the connection point of the inner wall of the atomizing end cover 50, the larger the cross-sectional area is, and the stronger its bending resistance is. The reinforcement structure 511 gradually decreases from the inner wall of the atomizing end cover 50 along the free end direction and transitions to a size that meets the elastic requirements of the conductive sheet 51. The transition is natural, and it is not easy to produce excessive local stress during the deformation of the conductive sheet 51. In order to ensure the strength of the reinforcement structure 511, the present embodiment can appropriately limit the ratio of the cross-sectional area of ​​the frustum at the junction with the inner wall of the atomization end cover 50 to the height of the frustum to ensure that the conductive sheet 51 will not be structurally damaged at the junction with the inner wall of the atomization end cover 50. In addition, since the cross-sectional area of ​​the reinforcement structure 511 at the root of the conductive sheet 51 is increased, the magnitude of the conductive current of the conductive sheet 51 can be further increased.

[0069] In this embodiment, the conductive sheet 51 also includes a first extension section 512 formed by the reinforcement structure 511 extending toward the electrode direction of the atomization device 30, a second extension section 513 formed by the end of the first extension section 512 opposite to the reinforcement structure 511 extending toward the electrode direction of the atomization device 30, and a third extension section 514 formed by the second extension section 513 extending from the end opposite to the first extension section 512. The extension direction of the first extension section 512 forms a first preset angle with the plane where the inner wall of the conductive sheet 51 formed by the atomization end cover 50 is located, the extension direction of the second extension section 513 forms a second preset angle with the extension direction of the first extension section 512, the length of the second extension section 513 is greater than the preset length, and the third extension section 514 is an arc convex toward the atomization device 30.

[0070] The first predetermined angle between the extension direction of the first extension section 512 and the plane perpendicular to the inner wall of the conductive sheet 51 formed by the atomizing end cover 50 refers to the angle formed by the plane portion of the first extension section 512 and the plane perpendicular to the inner wall. The second extension section 513 and the extension direction of the first extension section 512 form a second predetermined angle, which refers to the angle formed by the plane portion of the first extension section 512 and the plane portion of the second extension section 513.

[0071] The plane of the first extension section 512 and the inner wall is inclined at a certain angle. Since the electrode of the atomization device 30 is located directly above the inner wall, the direction of the force exerted by the electrode on the conductive sheet 51 is close to the direction perpendicular to the inner wall. In this way, when the second extension section 513 or the third extension section 514 of the conductive sheet 51 contacts the electrode of the atomization device 30, the force direction of the first extension section 512 and its extension direction also form a certain angle, so that after the free end is subjected to force, the first extension section 512 can bend at a larger angle to fully adapt to the different heights of the electrode of the atomization device 30. Since the tail of the second extension section 513 or the third extension section 514 is a part that may contact the electrode, and the rotation angle of the second extension section 513 will affect the displacement of the second extension section 513 and the third extension section 514, the length of the second extension section 513 and the angle between the extension direction of the second extension section 513 and the extension direction of the first extension section 512 are limited in this embodiment, so that the elastic coefficient of the rectified conductive sheet 51 and the displacement of the second extension section 513 and the third extension section 514 can meet the requirements of different electrode positions. In addition, the cross-sectional area of ​​the conductive sheet 51 gradually decreases from the first extension section 512 to the third extension section 514 as a whole, so that the magnitude of the bending moment to which the conductive sheet 51 and the section are subjected is adapted. Since the third extension section 514 is the section most likely to contact the electrode, in the present embodiment, the third extension section 514 is an arc convex toward the atomization device 30, so that the distance between each part of the third section and the electrode gradually changes. When the third extension section 514 contacts the electrode, in conjunction with the elastic deformation of the conductive sheet 51, the electrode can slide relatively along the convex arc to a position in good contact with the third extension section 514.

[0072] Example 2

[0073] like Figure 2 and Figure 3 As shown, this embodiment is further improved on the basis of Embodiment 1. In this embodiment, the first condensate adsorption member 70 is used to adsorb condensate and / or smoke oil. The first condensate adsorption member 70 is in contact with the inner wall of the atomization end cover 50 opposite to the atomization device 30. The inner wall of the atomization end cover 50 opposite to the electrode is spaced a preset distance from the end face of the oil tank 10 facing the atomization device 30.

[0074] After a period of use of the electronic cigarette, the oil and condensate in the cartridge 100 are likely to flow from the cartridge 100 to the circuit board of the electronic cigarette, causing damage to the circuit board. To this end, in this embodiment, a first condensate adsorbing member 70 is provided on the inner wall of the atomizing end cover 50 close to the electrode side to adsorb the condensate and oil of the accessories, and to isolate the area where the condensate is generated in the cartridge 100 from the circuit board in the electronic cigarette, thereby preventing the condensate from flowing from the area where the condensate is generated in the cartridge 100 to the circuit board of the electronic cigarette, thereby significantly extending the service life of the electronic cigarette.

[0075] like Figure 2 and Figure 8 As shown, in addition, in this embodiment, the cigarette cartridge 100 also includes a second condensate adsorbent 80 tightly attached to the end face of the oil tank 10 facing the cigarette holder 20, and the peripheral wall of the second condensate adsorbent 80 is tightly pressed against the inner wall of the cigarette holder 20, and is used to adsorb condensate and / or tobacco oil flowing toward the cigarette holder 20. The cigarette cartridge 100 also includes a condensate retaining ring 11 for blocking the condensate on the outer wall of the oil tank 10 from flowing toward the cigarette holder 20, and the condensate retaining ring 11 is an annular structure formed by the end face of the oil tank 10 facing the smoking port 21 of the cigarette holder 20 and extending toward the smoking port 21 of the cigarette holder 20.

[0076] The second condensate adsorbing member 80 may be made of high-density polyethylene or oil-absorbing cotton.

[0077] When the tobacco oil in the oil tank 10 leaks, it may flow into the smoking port 21 from the gap between the oil tank 10 and the inside of the cigarette holder 20. Therefore, in this embodiment, the second condensate adsorbent 80 also includes an adsorption layer for absorbing the tobacco oil flowing to the smoking port 21 of the cigarette holder 20. Since the second condensate adsorbent 80 is located between the opening of the oil tank 10 and the smoking port 21, the adsorption layer is arranged on the second condensate adsorbent 80 to absorb the tobacco oil before it flows into the smoking port 21. The adsorption layer can be composited on the second condensate adsorbent 80. When the second condensate adsorbent 80 is made of high-density polyethylene or oil-absorbing cotton, the entire second condensate adsorbent 80 serves as an oil-absorbing layer.

[0078] The outer surface of the second condensate adsorbent 80 includes a first surface facing the mouthpiece 20 and a second surface facing the oil tank 10, and the remaining surface is the peripheral wall of the second condensate adsorbent 80. When the peripheral wall of the second condensate adsorbent 80 is pressed against the inner wall of the mouthpiece 20, the interior of the mouthpiece 20 is divided into two mutually isolated spaces, one of which is connected to the smoking port 21 of the mouthpiece 20, and the other space includes the oil tank 10, the oil tank base 40, the atomizer and other components that are prone to produce condensate. Due to the separation effect of the second condensate adsorbent 80, the condensate is blocked outside the space connected to the smoking port 21 of the mouthpiece 20 and cannot enter the smoking port 21. Therefore, when the condensate in the cigarette cartridge 100 flows to the end surface of the oil tank 10 facing the mouthpiece 20, the second condensate adsorbent 80 can block the condensate and prevent the condensate from continuing to flow toward the smoking port 21 of the mouthpiece 20, thereby preventing the condensate in the cigarette cartridge 100 from flowing into the user's mouth.

[0079] The mouthpiece 20 is shell-shaped, and a pressing structure is formed on the inner wall of the shell-shaped mouthpiece 20 opposite to the second condensate adsorbent 80 to press the second condensate adsorbent 80 against the end surface of the oil tank 10 facing the smoking port 21 of the mouthpiece 20 toward the oil tank 10 .

[0080] In order to improve the isolation effect of the second condensate adsorbent 80, a pressing structure is arranged inside the cigarette holder 20 in this embodiment. The structure presses the second condensate adsorbent 80 against the end surface of the oil tank 10 facing the smoking port 21 of the cigarette holder 20 toward the oil tank 10, so that the position of the second condensate adsorbent 80 remains fixed, thereby preventing the second condensate adsorbent 80 from moving and causing condensate to leak into the smoking port 21.

[0081] The pressing structure is specifically a pressing plate formed by the inner wall of the shell-shaped cigarette holder 20 opposite to the second condensate adsorbent 80 extending toward the second condensate adsorbent 80, and the pressing plate presses the second condensate adsorbent 80 against the end face of the oil tank 10 facing the inhalation port 21 of the cigarette holder 20. When the cigarette cartridge 100 is assembled, the pressing plate is pressed against the second condensate adsorbent 80 in the direction of the oil tank 10 by the pressing force of the cigarette holder 20, so that it can be closely attached to the end face of the oil tank 10. In a specific implementation, the pressing plate includes a first pressing plate and a second pressing plate respectively located on both sides of the inhalation port 21. While pressing the second condensate adsorbent 80, the pressing plate is also closely attached to the second condensate adsorbent 80, so that the pressing plate and the second condensate adsorbent 80 can form an isolation structure as a whole, and fully isolate the area near the inhalation port 21 of the cigarette holder 20 that is in communication with the inhalation port 21 from other areas inside the cigarette cartridge 100.

[0082] like Fig. 9As shown, specifically, the condensate retaining ring 11 is located directly below the smoking port 21. In this embodiment, the condensate retaining ring 11 is arranged to face the smoking port 21 of the cigarette holder 20, and the condensate retaining ring 11 can effectively shield the area of ​​the oil tank 10 close to the cigarette holder 20, thereby preventing the condensate from flowing into the smoking port 20 from the area.

[0083] The outer wall of the condensate retaining ring 11 is formed with an inclined surface at a preset angle to the end surface of the oil tank 10 facing the cigarette holder 20. Setting the outer wall of the condensate retaining ring 11 as an inclined surface is conducive to the condensate sliding down the inclined surface and preventing the condensate from accumulating on the retaining ring.

[0084] In addition, in this embodiment, the inner wall of the atomization end cover 50 close to the electrode is spaced a preset distance from the end face of the oil tank 10 facing the atomization device 30. By setting a suitable spacing, the distance from the part of the cigarette cartridge 100 where condensation is easily generated to the circuit board can be increased, thereby reducing the probability of condensation flowing into the circuit board.

[0085] Example 3

[0086] This embodiment further improves the flue on the basis of embodiment 1. In this embodiment, the atomizing end cover 50 is provided with an air inlet 52, and the flue includes a first flue 61 and a second flue 62 and the first flue 61, the first flue 61 is located on the side of the oil tank 10 opposite to the smoking port 21, the atomizing device 30 is located in the first flue 61 on the side opposite to the oil tank 10, the second flue 62 is located on the side of the atomizing device 30 opposite to the air inlet 52, and the airflow direction of the second flue 62 forms a preset angle with the airflow direction of the first flue 61.

[0087] This embodiment abandons the structural form of the linear flue of the prior art, and divides the flue into a first flue 61 and a second flue 62 at a certain angle to each other. The first flue 61 is located on the side of the oil tank 10 opposite to the smoking port 21. Since the side of the atomizer core opposite to the oil tank 10 is located in the first flue 61, the air flows into the first flue 61 from the air inlet 52 and directly flows into the lower surface of the atomizer core, and fully contacts the smoke oil in the first flue 61, so that the atomized smoke can be fully burned. Since the second flue 62 is located on the side of the atomizer device 30 opposite to the air inlet 52, the second flue 62 is far away from the oil tank 10 and the connection position between the oil tank 10 and the atomizer device 30, and forms an angle with the first flue 61, so that the smoke oil can be fully mixed, atomized and burned in the first channel before entering the second flue 62, and the smoke oil in the oil tank 10 is difficult to leak from the position where the atomizer device 30 is connected to the oil tank 10 to the second flue 62.

[0088] One end of the second flue 62 is connected to the smoking port 21, and the other end is connected to the end of the first flue 61 opposite to the air inlet 52. The first flue 61 is used to allow the air flowing in from the air inlet 52 to fully burn with the atomized tobacco oil in the first flue 61 and then flow from the second flue 62 to the smoking port 21.

[0089] Both ends of the first flue 61 cross the atomization device, wherein the air inlet and the second flue 62 are respectively located at both ends of the flue 61 , so that the second flue 62 and the air inlet are staggered with each other, and the smoke oil is not easy to leak into the second flue 62 .

[0090] like Figure 3 As shown, in this embodiment, the oil tank base 40 and the oil tank 10 form a weld line ultrasonic welding structure that hermetically connects the oil tank base 40 and the oil tank 10 on the flue, and the weld line ultrasonic welding structure includes a first ultrasonic welding structure, which includes a first annular protrusion 41 formed by extending toward the oil tank 10 on a side where the oil tank base 40 is connected to the oil tank 10, and a first annular groove 12 formed by a side where the oil tank 10 is connected to the oil tank base 40 and is recessed in a direction opposite to the oil tank base 40, and the first annular protrusion 41 is inserted into the first annular groove 12 and connected by ultrasonic welding.

[0091] The smoke bomb 100 based on ultrasonic welding sealing of this embodiment is provided with a first ultrasonic welding structure for welding connection by ultrasonic welding at the position where the oil tank base 40 and the oil tank 10 are connected. The first ultrasonic welding structure is used to completely isolate the joint where the oil tank base 40 and the oil tank 10 on the flue are connected from the accommodating chamber. The smoke oil in the accommodating chamber of the oil tank 10 cannot enter the flue through the joint where the oil tank base 40 and the oil tank 10 on the flue are connected. The flue is sealed by ultrasonic welding, and there is no need to manually assemble the seals one by one, which is conducive to improving production efficiency in mass production. In addition, the sealing effect is no longer affected by human factors, and the sealing effect of mass products is highly stable.

[0092] Specifically, the first annular protrusion 41 is embedded in the first annular groove 12, and pressure is applied to the oil tank 10 and the oil tank base 40 in a direction perpendicular to the plane of the oil tank base 40, and the high-frequency vibration wave generated by the ultrasonic welding machine is transmitted to the contact surface of the first annular protrusion 41 and the first annular groove 12, so that the surfaces of the two are rubbed against each other to form a fusion between the molecular layers, thereby forming an annular welding area surrounding the outside of the flue seam and enclosing the flue seam therein. The annular welding area can be any annular shape that can form a closed area, such as a circular ring, an elliptical ring, a rectangle, etc.

[0093] In order to improve the sealing effect, in this embodiment, the end of the first annular protrusion 41 facing the first annular groove 12 is formed with a wedge structure ultrasonically welded with the first annular groove 12, and the wedge structure is formed by a first welding surface and a second welding surface intersecting at a preset angle. The oil tank 10 is formed with a first column extending from the end surface of the oil tank 10 facing the oil tank base 40 to the end surface of the oil tank 10 facing the smoking port 212, and the first column includes a hollow structure for forming a flue, and the first annular groove 12 is formed on the end surface of the first column facing the oil tank base 40. In order to form a flue with a stable structure, in this embodiment, the axial direction of the oil tank 10 is provided with a column in the same direction as the airflow direction in the flue, and the middle part of the column is made into a hollow structure, and the hollow structure is used as a flue.

[0094] The end of the first annular protrusion 41 of the present embodiment is set as a wedge-shaped structure, that is, the end of the cross section of the first annular protrusion 41 facing the first annular groove 12 is a wedge-shaped structure. On the one hand, since the wedge-shaped structure is easier to embed into the first annular groove 12, it can be convenient for positioning during assembly, which ensures the subsequent welding effect. On the other hand, the wedge-shaped structure is composed of a first welding surface and a second welding surface, which can form two inner and outer annular welding areas in cooperation with the first annular groove 12, and can achieve two layers of sealing for the flue. A slight change to the original structure can double the reliability of the sealing. The angle at which the first welding surface and the second welding surface intersect can be determined according to the sealing effect.

[0095] In addition, in this embodiment, the oil tank base 40 and the oil tank 10 also form a second ultrasonic welding structure that isolates the external space of the cigarette cartridge 100 from the accommodating chamber. The second ultrasonic welding structure is formed on the outside of the accommodating chamber and surrounds the accommodating chamber for at least one circle to close the accommodating chamber.

[0096] The second ultrasonic welding structure seals the storage chamber containing the smoke oil and isolates the storage chamber from the outside, which can effectively prevent the smoke oil in the oil tank 10 from leaking out of the smoke cartridge 100. The second ultrasonic welding structure can be arranged near the outer periphery of the oil tank 10.

[0097] In specific implementation, the second ultrasonic welding structure includes a second annular protrusion 2 formed by extending toward the oil tank 10 on the side where the oil tank base 40 is connected to the oil tank 10, and a second annular groove formed by being recessed in a direction opposite to the oil tank base 40 on the side where the oil tank 10 is connected to the oil tank base 40, and one end of the second annular protrusion 2 facing the second annular groove is inserted into the second annular groove and connected to the second annular groove by ultrasonic welding.

[0098] In order to improve the sealing effect, the second annular protrusion 2 of this embodiment has a wedge-shaped structure ultrasonically welded to the second annular groove at one end thereof, and the wedge-shaped structure is formed by a second welding surface and a second welding surface intersecting at a preset angle.

[0099] The oil tank 10 is sealed by ultrasonic welding, which can realize assembly line-type large-scale production, significantly improving the production efficiency of the cigarette cartridge 100. At the same time, the sealing effect is not affected by differences in manual operation levels, and the sealing effect of batch products is stable.

[0102] The power supply device may be integrated on the cigarette rod 200, and the cigarette cartridge 100 and the cigarette rod 200 are connected in a detachable manner to facilitate replacement of the cigarette cartridge 100. The power supply device and the cigarette cartridge 100 may be electrically connected to the electrode through the conductive sheet 51.
