Description

Technical Field

[0001] The present invention relates to the technical field of smoking articles, and in particular to a cigarette cartridge and an electronic cigarette in which an electrode and an atomization end cover are integrally formed. 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 through the flue set in the cigarette cartridge for the user to inhale. The cigarette rod mainly provides electrical energy for the atomizer in the cigarette cartridge, so it is necessary to reliably connect the power supply of the cigarette rod with the atomizer of the cigarette cartridge. In the prior art, the power supply in the cigarette rod is mainly electrically connected to the atomizer in the cigarette cartridge through an electrode. This connection method requires a through hole to be opened on the atomizer end cover of the cigarette cartridge, so that the electrode can pass through the through hole of the atomizer end cover to enter the inside of the atomizer end cover and contact the electrode of the atomizer located inside the atomizer end cover to form an electrical connection. The cigarette cartridge stores oil, and the oil is easy to leak from the through hole on the atomizer end cover for the electrode to pass through to the outside of the flue. In addition, the diameter of the electrode is limited by the size of the through hole and is not easy to be made too large, so the current that the electrode can conduct is also limited. In addition, the electrode connection method requires the installation of electrodes one by one during the production process, resulting in low production efficiency of electronic cigarette products and unsuitability for large-scale assembly line production. Summary of the invention

[0004] In view of this, the utility model provides a cigarette cartridge and an electronic cigarette in which an electrode and an atomization end cover are integrally formed, so as to solve the technical problems of low production efficiency, small conduction current, and leakage of cigarette oil caused by the electrical connection method between the existing electronic cigarette power supply and the atomization device.

[0034] Embodiment 1:

[0035] like Figure 1 and Figure 2As shown, the present embodiment provides a cigarette cartridge 100 in which an electrode and an atomizing end cap are integrally formed. The cigarette cartridge 100 in which the electrode and the atomizing end cap are integrally formed in the present 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 atomizing device 30 of the cigarette cartridge 100. The power supply provides electrical energy to the atomizing device 30 of the cigarette cartridge 100, and the atomizing 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 cigarette holder 20, a negative pressure is formed at the cigarette oil outlet of the atomizing device 30 of the cigarette cartridge 100. Under the action of the 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 smoking port 21 of the cigarette holder 20 along the internal air flow channel of the cigarette cartridge 100 for the convenience of the user to inhale.

[0036] like Figure 2 and Figure 3 As shown, the cigarette cartridge 100 of this embodiment, in which the electrode and the atomization end cap are integrally formed, forms an electrical connection between the contact point in contact with the outer wall of the atomization end cap 50 and the electrode of the atomization device 30 located inside the atomization end cap 50 through the atomization end cap 50 and the conductive sheet 51 integrally formed with the atomization end cap 50 inside the atomization end cap 50. The current of the power supply can be conducted from the outside of the cigarette cartridge 100 to the electrode of the atomization device 30 located inside the cigarette cartridge 100, and the conduction method does not require any component to penetrate the atomization end cap 50 from the outside to the inside, so the atomization end cap 50 does not need to form a through hole or other structure that is easy to leak smoke oil, effectively avoiding the leakage of smoke oil from the structure forming an electrical connection on the atomization end cap 50. In addition, the conduction method of this embodiment does not require the installation of electrodes, so the process of following the electrodes is omitted in product production, so that the production efficiency is significantly improved. In addition, since there is no need to penetrate the atomizing end cover 50, the shape and size of the conductive sheet 51 are not limited by the connection structure, and the cross-sectional area of ​​the conductive sheet 51 can be increased to a greater extent, so that the conductive sheet 51 can conduct a larger current.

[0037] like Figure 2 and Figure 3 As shown, the cigarette cartridge 100 in which the electrode and the atomization end cover are integrally formed in 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] The atomization device 30 includes an atomization core and a coating layer coated on the outer wall of the atomization core. In this embodiment, the atomization core is preferably a ceramic atomization core with good high temperature resistance. A heating component is provided in the atomization core, and when the atomization core is powered on, the heating component generates heat for atomizing the e-liquid.

[0044] The flue guides the smoke formed by the smoke oil being atomized by the atomization device 30 to flow toward the smoke outlet 21;

[0045] The oil tank base 40 is connected to one end of the oil tank 10 close to the atomizing device 30;

[0046] 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 .

[0047] An atomizing end cover 50 is provided on the side of the oil tank base 40 facing the atomizing device 30;

[0048] The conductive sheet 51 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.

[0049] 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.

[0050] 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 .

[0051] like Figure 3 and Figure 4As 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.

[0052] 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.

[0053] Since the atomizing end cap 50 is a conductor as a whole, the current can be conducted from any area outside the atomizing end cap 50 to any area of ​​the wall of the atomizing end cap 50 without the need for other components to penetrate the atomizing end cap 50 from the outside to the inside. And using the entire atomizing end cap 50 as a conductor can increase the size of the current that can be conducted at a cost compared to the electrodes in the prior art, so that the atomization effect of the atomizing device 30 is significantly improved. In order to make the contact of the cigarette rod 200 reliably contact the outer wall of the atomizing end cap 50. At least one raised portion facing the contact of the cigarette rod 200 is provided at a position corresponding to the contact on the outer surface of the atomizing end cap 50 facing the electrode of the cigarette rod 200, and the raised portion maintains a certain height difference with the outer surface of the atomizing end cap 50 facing the electrode of the cigarette rod 200, 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 .

[0054] 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.

[0055] like Figure 4 and Figure 5 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.

[0056] 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 frustum, and the closer the reinforcement structure 511 is to the connection 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 is gradually reduced 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.

[0057] 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.

[0058] 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.

[0059] The first extension section 512 is inclined at a certain angle to a plane perpendicular to the inner wall. 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 also forms a certain angle with its extension direction, 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.

[0060] Example 2

[0061] 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.

[0062] After a period of use, the e-cigarette oil and condensate in the cartridge 100 are likely to flow from the cartridge 100 to the circuit board of the e-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 e-cigarette, to prevent the condensate from flowing from the area where the condensate is generated in the cartridge 100 to the circuit board of the e-cigarette, thereby significantly extending the service life of the e-cigarette.

[0063] like Figure 2 and Figure 6 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.

[0064] The second condensate adsorbing member 80 may be made of high-density polyethylene or oil-absorbing cotton.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 the area near the inhalation port 21 of the cigarette holder 20 that is in communication with the inhalation port 21 is fully isolated from other areas inside the cigarette cartridge 100.

[0070] Specifically, the condensate retaining ring 11 is located directly below the mouthpiece 21. In this embodiment, the condensate retaining ring 11 is arranged to face the mouthpiece 20 and the mouthpiece 21, and the condensate retaining ring 11 can effectively shield the area of ​​the oil tank 10 near the mouthpiece 20 to prevent the condensate from flowing into the mouthpiece 20 from the area.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] The cigarette cartridge 100 of this embodiment, in which the electrode and the atomization end cap are integrally formed, 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.

[0078] 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.

[0079] 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, a column with the same direction as the airflow direction in the flue is set in the axial direction of the oil tank 10, and the middle part of the column is made into a hollow structure, and the hollow structure is used as a flue.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] The oil tank 10 is sealed by ultrasonic welding, which can realize assembly line-type large-scale production, and the production efficiency of the cigarette cartridge 100 in which the electrode and the atomization end cover are integrally formed is significantly improved. 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.
