[0002] Currently available atomizing devices often suffer from condensation buildup during use. To address this, existing technology typically incorporates a long strip of cotton in the central tube of the cartridge mouthpiece to absorb the condensation. However, the suction force draws the condensation out of the cotton, causing it to splash into the user's mouth and negatively impacting the experience. Furthermore, as the cotton strip length increases, its absorption of flavor components in the atomized gas becomes more pronounced, leading to the loss of sweetness and affecting the purity of the atomized gas's flavor. Utility Model Content

[0003] The main purpose of this utility model is to provide a cartridge structure and a replaceable cartridge electronic atomizing device, aiming to solve the technical problem that existing atomizing devices use a long strip of cotton in the central tube of the cartridge mouthpiece to absorb condensate. Due to the suction, the condensate in the long strip of cotton is drawn out, making it easy for the condensate to fly into the mouth, thus affecting the atomized taste.

[0004] In order to achieve the above-mentioned utility model objectives, this utility model proposes a tobacco cartridge structure, including a tobacco cartridge mouthpiece, a base assembly, a heating assembly, and a liquid absorption assembly;

[0010] Furthermore, the cartridge base includes a first base body, the liquid absorption component further includes a condensing cotton, the first base body is connected to the connecting part, the condensing cotton is located on the side of the heating component away from the oil-absorbing cotton, and the condensing cotton is detachably disposed inside the first base body.

[0011] Furthermore, the cartridge base also includes a first sleeve, and the oil-sealing base includes a second base body and a second sleeve. The first sleeve is disposed on the side of the first base body near the contact portion, and the second sleeve is disposed on the second base body, with the first sleeve sleeved inside the second sleeve.

[0012] Furthermore, the connecting hole is disposed within the second base body, the oil-absorbing cotton is disposed within the connecting hole, the oil-absorbing cotton has a central hole, and the nozzle channel, the connecting hole, the central hole and the atomizing chamber are sequentially connected.

[0033] Reference Figures 1-2 This embodiment provides a tobacco cartridge structure, including a tobacco cartridge mouthpiece 1, a base assembly, a heating assembly 3, and a liquid absorption assembly 4;

[0034] The cartridge mouthpiece 1 is provided with a mouthpiece channel 5. The cartridge mouthpiece 1 is detachably connected to the base assembly, and the cartridge mouthpiece 1 is connected to the base assembly through the mouthpiece channel 5.

[0035] The heating element 3 and the liquid absorption element 4 are respectively disposed in the base assembly;

[0036] The liquid absorption component 4 includes an oil-absorbing cotton 40, which abuts against one end of the suction channel 5 near the base component, and is located between the heating component 3 and the suction channel 5.

[0037] In the above embodiment, the cartridge structure includes a cartridge mouthpiece 1, a base assembly, a heating element 3, and a liquid absorption element 4. The cartridge mouthpiece 1 is the part that the user directly contacts. It has a through mouthpiece channel 5 inside to guide the atomized gas to the user's mouth. The cartridge mouthpiece 1 is detachably connected to the base assembly, and the cartridge mouthpiece 1 is connected to the base assembly through the mouthpiece channel 5 to ensure that the gas can be discharged from the inside of the base through the mouthpiece channel 5. Both the heating element 3 and the liquid absorption element 4 are disposed inside the base assembly, and the heating element 3 and the liquid absorption element 4 are arranged correspondingly inside the base assembly. The heating element 3 is used to heat the atomized e-liquid. The liquid absorption element 4 includes an oil-absorbing cotton 40, which abuts against the end of the mouthpiece channel 5 near the base assembly, so that the oil-absorbing cotton 40 is placed at the bottom of the mouthpiece channel 5, just above the heating element 3. The oil-absorbing cotton 40 is located between the heating element 3 and the nozzle channel 5. The nozzle channel 5 is a straight channel. When using the device, the user's mouth is in contact with the outlet end of the nozzle channel 5, and the nozzle channel 5 is inclined downward relative to the human body. This allows the liquid condensed on the inner wall of the nozzle channel 5 to flow down naturally and be absorbed by the oil-absorbing cotton 40 at the outlet end of the nozzle channel 5. Therefore, because the nozzle channel 5 has a certain length and the oil-absorbing cotton 40 is located at the end of the nozzle channel 5 away from the outlet, even if the suction is strong, it can be ensured that the condensate in the oil-absorbing cotton 40 will not be sucked out and splashed into the user's mouth. This reduces the possibility of condensate splashing into the user's mouth and prevents the loss of sweet ingredients due to excessive cotton strip length, thereby improving the overall atomized taste and user experience.

[0038] Reference Figures 1-2 In one embodiment, the cartridge mouthpiece 1 includes a connecting portion 10 and a contact portion 11 integrally connected to the connecting portion 10. The base assembly is snapped into the connecting portion 10 and abuts against the outer wall of the mouthpiece channel 5. The mouthpiece channel 5 is disposed in the contact portion 11.

[0039] In the above embodiment, the cartridge mouthpiece 1 consists of two parts: a connecting part 10 and a contact part 11. The connecting part 10 is the part that connects the cartridge mouthpiece 1 to the base assembly, so that the base assembly is snapped into the connecting part 10, and the top of the base assembly abuts against the outer wall of the mouthpiece channel 5. The contact part 11 is the part that directly contacts the user's lips. The mouthpiece channel 5 is located at the center of the contact part 11 and extends along the entire length of the contact part 11, so that the mouthpiece channel 5 passes through the upper and lower ends of the contact part 11, and is used to guide the atomized vapor from the inside of the device to be smoothly transmitted to the user's mouth. The connecting part 10 and the contact part 11 are integrally formed. The base assembly and the connecting part 10 are connected by a tight snap-fit ​​method, which makes it extremely simple and quick to replace the cartridge, greatly improving the user experience.

[0040] Reference Figures 1-2 In one embodiment, the base assembly includes a cartridge base 20 and an oil-sealing base 21. The oil-sealing base 21 is disposed at one end of the cartridge base 20 near the contact portion 11. The oil-sealing base 21 and the cartridge base 20 together form an atomizing chamber 22. The oil-sealing base 21 is provided with a connecting hole, and the mouthpiece channel 5 is connected to the atomizing chamber 22 through the connecting hole.

[0041] In the above embodiment, the base assembly consists of two parts: a cartridge base 20 and a sealing base 21. The cartridge base 20 is a bottom support structure, while the sealing base 21 is located at the end of the cartridge base 20 near the contact portion 11. Its function is to prevent e-liquid leakage and ensure the airtightness of the internal space. The cartridge base 20 and the sealing base 21 together form a sealed atomizing chamber 22. The heating component 3 and the liquid absorption component 4 are placed inside the atomizing chamber 22, where the heating and atomization of the e-liquid takes place. The sealing base 21 is located between the cartridge base 20 and the contact portion 11, and the top of the sealing base 21 is in close contact with the contact portion 11. The sealing base 21 is provided with a connecting hole, which allows the mouthpiece channel 5 to connect with the atomizing chamber 22, thereby forming a complete airflow path and improving heat utilization efficiency.

[0042] Reference Figures 1-2 In one embodiment, the cartridge base 20 includes a first base body 201, and the liquid absorption component 4 further includes a condensing cotton 41. The first base body 201 is connected to the connecting part 10. The condensing cotton 41 is located on the side of the heating component 3 away from the oil-absorbing cotton 40, and the condensing cotton 41 is detachably disposed inside the first base body 201.

[0043] In the above embodiment, the cartridge base 20 includes a first base body 201, the outer wall of the first base body 201 is engaged with the inner wall of the connecting part 10, and the liquid absorption component 4 also includes a condensing cotton 41. The condensing cotton 41 is located on the side of the heating component 3 away from the oil-absorbing cotton 40. Its main function is to absorb excess condensate in the atomizing chamber 22. At the same time, the condensing cotton 41 is detachably arranged in the first base body 201. There are two symmetrical condensing cottons 41, so that the two separate and symmetrical condensing cottons 41 are arranged inside the first base body 201, forming a through hole between them, which is mainly used for the electrode wire of the heating wire to pass through. This allows the condensing cotton 41 to effectively absorb the condensate generated by temperature changes, while not hindering the operation of the heating wire. This improves the absorption efficiency of the condensate, reduces the possibility of the condensate entering the user's mouth with the vapor flow, and provides a more comfortable user experience.

[0044] Reference Figures 1-2 In one embodiment, the cartridge base 20 further includes a first sleeve 202, and the oil-sealing base 21 includes a second base body 210 and a second sleeve 211. The first sleeve 202 is disposed on the side of the first base body 201 near the contact portion 11, and the second sleeve 211 is disposed on the second base body 210, with the first sleeve 202 sleeved inside the second sleeve 211.

[0045] In the above embodiment, the cartridge base 20 further includes a first sleeve 202, which is located on the side of the first base body 201 near the contact portion 11. The sealing base 21 is composed of a second base body 210 and a second sleeve 211, with the second sleeve 211 mounted on the second base body 210. The first base body 201 and the first sleeve 202 are integral parts, as are the second base body 210 and the second sleeve 211. The inner diameter of the first sleeve 202 is smaller than the inner diameter of the second sleeve 211, allowing the first sleeve 202 to be fitted onto the cartridge. Inside the second sleeve 211, the side wall of the second sleeve 211 contacts the inner wall of the connecting part 10, and the top of the second base body 210 contacts the contact part 11. That is, the atomizing chamber 22 is actually a space formed by the two sleeves (the first sleeve 202 and the second sleeve 211) and the two base bodies (the first base body 201 and the second base body 210). By fitting the first sleeve 202 inside the second sleeve 211, a double-layer protection mechanism is formed, which greatly enhances the sealing of the overall structure and effectively prevents the occurrence of e-liquid leakage.

[0046] Furthermore, a connecting hole is located inside the second base body 210, and the oil-absorbing cotton 40 is cleverly placed inside the connecting hole, contacting the bottom of the nozzle channel 5. This ensures that the condensate can be effectively absorbed without affecting the normal flow of steam. The oil-absorbing cotton 40 also has a central hole, which is precisely aligned with the connecting hole. The nozzle channel 5, the connecting hole, the central hole, and the atomizing chamber 22 are connected in sequence to form a complete airflow channel. First, the nozzle channel 5, as the part that directly contacts the user, guides the treated steam to the user's mouth. Second, the connecting hole, located inside the second base body 210, connects the nozzle channel 5 to the atomizing chamber 22, ensuring that the steam can flow smoothly from the atomizing chamber 22 to the nozzle channel 5. Finally, the central hole on the oil-absorbing cotton 40 ensures that even with the oil-absorbing cotton 40 present, the airflow can still pass through without obstruction, avoiding discomfort caused by airflow obstruction.

[0047] Reference Figures 1-2 In one embodiment, the cartridge base 20 further includes a support frame 203, which is disposed on the side of the first base body 201 near the second base body 210. The heating component 3 is disposed between the support frame 203 and the second base body 210, and the heating component 3 is arranged perpendicular to the support frame 203 and the second base body 210 respectively.

[0048] In the above embodiment, the cartridge base 20 further includes a support frame 203, which is disposed on the side of the first base body 201 near the second base body 210. A certain gap is formed between the side wall of the support frame 203 and the side wall of the first sleeve 202. The heating element 3 is disposed between the support frame 203 and the second base body 210, and the heating element 3 is arranged perpendicularly to the support frame 203 and the second base body 210. A certain gap is maintained between the top of the support frame 203 and the bottom of the second base body 210, forming a space for accommodating the heating element. 3. The heating element 3 is located within the interval, so that its opposite sides abut against the support frame 203 and the second base body 210 respectively, thereby achieving a stable snap-fit ​​effect. The heating element 3 consists of oil-guiding cotton and heating wire. The oil-guiding cotton is placed horizontally between the support frame 203 and the second base body 210, making it perpendicular to the mouthpiece channel 5, ensuring that the oil can be evenly diffused around the heating wire. The heating wire is wrapped around the surface of the oil-guiding cotton. When the current passes through the heating wire, it will quickly heat and evaporate the e-liquid in the oil-guiding cotton to form fine vapor, ensuring uniform heat distribution and efficient energy utilization.

[0049] Reference Figures 1-2In one embodiment, the cartridge structure further includes a cartridge electrode 6 and a plurality of magnets 7. The cartridge electrode 6 and the magnets 7 are respectively disposed on the side of the first base body 201 away from the oil sealing base 21. The cartridge electrode 6 is connected to the heating component 3 and is located between adjacent magnets 7.

[0050] In the above embodiment, the cartridge structure also includes a cartridge electrode 6 and multiple magnets 7. The cartridge electrode 6 is a key component responsible for providing power to the heating element 3. It is electrically connected to the heating wire to ensure that the current can pass smoothly through the heating wire for heating operation. The multiple magnets 7 are used to enhance the fixation and stability of the device. In particular, when docking with other components or external devices, the magnets 7 can play an auxiliary positioning and stabilizing role. The cartridge electrode 6 and the multiple magnets 7 are set on the side of the first base body 201 away from the oil sealing base 21, and the cartridge electrode 6 is located between adjacent magnets 7. The cartridge electrode 6 and the multiple magnets 7 are all located on the same radial line, that is, their centers are located on the same straight line, which effectively optimizes the power transmission path and improves the overall stability and durability of the device.

[0051] Furthermore, the cartridge structure also includes a sealing ring 8, which is detachably mounted on the first base body 201. The sealing ring 8 is made of an elastic material, and its diameter is smaller than the diameter of the cross-section of the first base body 201, so that the sealing ring 8 is preferably mounted in the slot of the first base body 201. The main function of the sealing ring 8 is to prevent any possible leakage of e-liquid or other liquids, ensuring the stability and reliability of the device during long-term use.

[0052] This embodiment also proposes a cartridge-type electronic cigarette atomizing device, including the cartridge structure described in any of the above embodiments, which not only improves the user experience and convenience, but also significantly enhances the safety, reliability and durability of the device.
