[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0032] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.
[0033] An electronic atomizing device is an electronic product that mimics cigarettes, producing similar smoke, taste, and sensation. It works by atomizing e-liquid into vapor for the user to inhale. An electronic atomizing device includes a cartridge for storing the e-liquid and an atomizing coil for heating the e-liquid.
[0034] Currently, pod-based e-cigarette devices typically integrate the atomizer core, liquid reservoir, and mouthpiece into a single, complex structure, resulting in higher costs. Furthermore, the risk of leakage is high when the liquid aerosol matrix in the reservoir is transported to the atomizer core.
[0035] In view of the above problems, this application provides a cigarette cartridge and an electronic atomizing device, aiming to solve the technical problems of complex structure, high cost and high risk of leakage of cigarette cartridges.
[0036] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0037] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a cartridge for use in an electronic atomizing device. The cartridge includes a first housing 1, a second housing 2, and an oil-retaining cotton 4.
[0038] The first housing 1 has a first receiving groove 11. The second housing 2 has a second receiving groove 21. The first housing 1 and the second housing 2 are connected, and the first receiving groove 11 and the second receiving groove 21 are connected and combined to form an oil storage cavity 3. An oil storage cotton 4 is housed in the oil storage cavity 3. The oil storage cotton 4 includes a plurality of transverse fibers extending in a horizontal direction.
[0039] In the e-cigarette cartridge of this application embodiment, the first shell 1 and the second shell 2 are connected and combined to form an oil storage cavity 3, which can simplify the composition of the e-cigarette cartridge, making the structure of the e-cigarette cartridge simpler and more compact, and can save the processing cost and assembly cost of the e-cigarette cartridge.
[0040] It should be noted that the vertical direction mentioned in this application is parallel to the Z direction in the figure, and the horizontal direction mentioned in this application is parallel to the X direction in the figure.
[0041] It should be noted that, under normal operating conditions, the electronic atomizing device is vertically oriented, and the first housing 1 and the second housing 2 in the cartridge are vertically distributed. The e-liquid within the reservoir cotton 4 flows vertically downwards under its own weight, compressing the reservoir cotton 4 and causing it to be squeezed out.
[0042] In the e-liquid cartridge of this application embodiment, the horizontally extending transverse fibers in the oil-retaining cotton 4 can guide the e-liquid in the oil-retaining cotton 4 to flow horizontally, and can also reduce the squeezing force of the e-liquid on the oil-retaining cotton 4 in the vertical direction. This can prevent the e-liquid in the oil-retaining cotton 4 from flowing and squeezing the oil-retaining cotton 4 under its own weight, thereby preventing the e-liquid in the oil-retaining cotton 4 from flowing out, and thus reducing the risk of leakage of the oil-retaining cotton 4 and the e-liquid cartridge.
[0043] It should be noted that in the electronic atomizing device, the atomizer coil is housed within the e-liquid reservoir 4, and the reservoir 4 provides e-liquid to the atomizer coil. The e-liquid within the reservoir 4 is horizontally transferred to the atomizer coil, which heats the e-liquid transferred from the reservoir 4 to generate vapor. In this embodiment, the reservoir 4 includes multiple transverse fibers extending horizontally, resulting in a higher horizontal conduction rate of e-liquid within the reservoir 4 compared to conventional reservoir 4. This reduces the risk of the atomizer coil burning out due to untimely e-liquid transfer and minimizes the risk of coil burnt-out.
[0044] It should be noted that if the e-liquid in the reservoir cotton 4 is transported too quickly in the horizontal direction, too much e-liquid will enter the atomizer core. Since the heating capacity of the atomizer core is limited, too much e-liquid will lead to incomplete combustion and waste. In severe cases, the remaining e-liquid may even flow out of the cartridge through the atomizer core, increasing the risk of cartridge leakage.
[0045] In view of the above problems, in some embodiments, the oil-absorbing cotton 4 also includes vertical fibers extending in a vertical direction, and the oil-absorbing cotton 4 is woven from horizontal fibers and vertical fibers.
[0046] By adopting the above technical solution, the vertically extending fibers can slow down the flow speed of e-liquid in the horizontal direction within the oil storage cotton 4, so that not too much e-liquid enters the atomizing core, thereby allowing the e-liquid to be fully burned by the atomizing core, reducing waste, and also reducing the risk of e-liquid leakage.
[0047] Please refer to Figure 3 In some embodiments, the outer wall of the oil-storing cotton 4 is provided with a plurality of liquid guiding grooves 41 arranged in a vertical direction.
[0048] In the above embodiment, the liquid guide groove 41 can guide the e-liquid to flow vertically. If the e-liquid in the oil storage cotton 4 is transported too quickly in the horizontal direction, the liquid guide groove 41 can guide the remaining e-liquid along the outer wall of the oil storage cotton 4 to the bottom of the oil storage cavity 3 for the oil storage cotton 4 to reabsorb. This can prevent too much e-liquid from entering the atomizing core, so that the e-liquid can be fully burned by the atomizing core, reducing waste and also reducing the risk of e-liquid leakage.
[0049] Please refer to Figure 3 In some embodiments, the first housing 1 is provided with a first plug-in structure 12, and the second housing 2 is provided with a second plug-in structure 22, and the second plug-in structure 22 is engaged with the first plug-in structure 12.
[0050] In the above embodiments, using a plug-in connection to connect the first housing 1 and the second housing 2 can simplify the connection relationship between the first housing 1 and the second housing 2, reduce the assembly difficulty of the e-cigarette cartridge, and reduce the assembly cost of the e-cigarette cartridge.
[0051] In some embodiments, the end faces around the opening of the first receiving groove 11 and the end faces around the opening of the second receiving groove 21 are both planes, and the end faces around the opening of the first receiving groove 11 and the end faces around the opening of the second receiving groove 21 can fit tightly together to ensure the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2, and reduce the risk of e-liquid in the oil storage cavity 3 leaking from the connection between the first housing 1 and the second housing 2.
[0052] In some embodiments, the first plug-in structure 12 includes a plug-in portion, and the second plug-in structure 22 includes a mating portion. The plug-in portion of the first plug-in structure 12 is plugged into the mating portion of the second plug-in structure 22 one-to-one, so that the first housing 1 and the second housing 2 can be connected to each other.
[0053] Please refer to Figure 3 and Figure 4 In some embodiments, the insertion part is a protruding post protruding from the end face around the slot of the first receiving groove 11, and the mating part is a plug hole or slot opened on the second housing 2, with the opening of the plug hole or the slot of the slot flush with the end face around the slot of the second receiving groove 21.
[0054] When the plug-in part in the first plug-in structure 12 is plugged into the mating part in the second plug-in structure 22 one by one, it does not affect the tightness of the fit between the end face around the opening of the first receiving groove 11 and the end face around the opening of the second receiving groove 21, so as to ensure the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2, and reduce the risk of the e-liquid in the oil storage cavity 3 leaking from the connection between the first housing 1 and the second housing 2.
[0055] In some embodiments, the first plug-in structure 12 includes a mating portion, and the second plug-in structure 22 includes a plugging portion. The plugging portion of the second plug-in structure 22 is plugged into the mating portion of the first plug-in structure 12 one-to-one, so that the first housing 1 and the second housing 2 can be connected to each other.
[0056] In some embodiments, the mating part is a hole or slot formed on the first housing 1, the opening of the hole or the slot is flush with the end face around the opening of the first receiving groove 11, and the insertion part is a protrusion protruding from the end face around the opening of the second receiving groove 21.
[0057] When the plug-in part in the second plug-in structure 22 is plugged into the mating part in the first plug-in structure 12 one by one, it does not affect the tightness of the fit between the end face around the opening of the first receiving groove 11 and the end face around the opening of the second receiving groove 21, so as to ensure the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2 and reduce the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2 in the oil storage cavity 3.
[0058] Please refer to Figure 3 In some embodiments, both the first plug-in structure 12 and the second plug-in structure 22 include a plug-in portion and a mating portion. The plug-in portion of the first plug-in structure 12 is plugged into the mating portion of the second plug-in structure 22 one-to-one, and the plug-in portion of the second plug-in structure 22 is plugged into the mating portion of the first plug-in structure 12 one-to-one, so that the first housing 1 and the second housing 2 can be connected to each other.
[0059] The insertion and mating parts in the first insertion structure 12 and the insertion and mating parts in the second insertion structure 22 can be configured with reference to the configuration of the insertion and mating parts in the above embodiments, so that after the first insertion structure 12 and the second insertion structure 22 are inserted together, the tightness of the fit between the end faces around the opening of the first receiving groove 11 and the end faces around the opening of the second receiving groove 21 is not affected, so as to ensure the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2 and reduce the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2.
[0060] Please refer to Figure 3 In some embodiments, the first housing 1 is centrally symmetrical about its center line, and the second housing 2 is centrally symmetrical about its center line.
[0061] By adopting the above technical solution, after the first housing 1 rotates around its centerline by a certain angle and / or the second housing 2 rotates around its centerline by a certain angle, the first insertion structure 12 on the first housing 1 and the second insertion structure 22 on the second housing 2 can still be inserted into each other, and the first housing 1 and the second housing 2 can also form a cartridge. The first receiving groove 11 and the second receiving groove 21 can also be connected and combined to form an oil storage cavity 3. That is, when assembling the cartridge, there is no need to strictly control the angle of the first housing 1 and the second housing 2, so that the cartridge can be blindly assembled, thereby reducing the assembly difficulty and cost of the cartridge.
[0062] Optionally, the cross-sections of the first shell 1 and the second shell 2 in the horizontal direction are equilateral symmetric figures such as circles, squares, rectangles, or ellipses.
[0063] like Figure 3 In the illustrated embodiment, the first housing 1 and the second housing 2 have rectangular cross-sections in the horizontal direction. The first insertion structure 12 includes two insertion portions and two mating portions, with the two insertion portions and two mating portions diagonally arranged on the first housing 1. The second insertion structure 22 also includes two insertion portions and two mating portions, with the two insertion portions and two mating portions diagonally arranged on the second housing 2. When the first housing 1 and the second housing 2 are connected, the first insertion structure 12 on the first housing 1 and the second insertion structure 22 on the second housing 2 are engaged. Even after the first housing 1 is rotated 180 degrees around its centerline and / or the second housing 2 is rotated 180 degrees around its centerline, the first insertion structure 12 on the first housing 1 and the second insertion structure 22 on the second housing 2 can still be engaged.
[0064] Please refer to Figure 3 In some embodiments, the first housing 1 and the second housing 2 have the same structure.
[0065] By adopting the above technical solution, only one drawing needs to be made, only one mold needs to be opened, and only one production line is needed when producing the first shell 1 and the second shell 2. Moreover, the production process of the production line does not need to be modified after it is determined, which can reduce the production cost of the e-cigarette cartridges.
[0066] In other embodiments, please refer to Figure 4 and Figure 5 In some embodiments, the first insertion structure 12 includes a male stop on the end face disposed around the opening of the first receiving groove 11, and the second insertion structure 22 includes a female stop on the second housing 2, the male stop extending through the opening of the second receiving groove 21 into the second receiving groove 21, and the male stop being accommodated within the female stop.
[0067] When the male stop is placed inside the female stop, the male stop can cover the contact area between the end face around the opening of the first receiving groove 11 and the end face around the opening of the second receiving groove 21, thereby increasing the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2 and reducing the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2.
[0068] Please refer to Figure 4 In some embodiments, the male stop is circumferentially arranged around the end face of the opening of the first receiving groove 11, and the female stop is circumferentially arranged around the opening of the second receiving groove 21. This allows the male stop to cover the entire contact area of the end face around the opening of the first receiving groove 11 and the end face around the opening of the second receiving groove 21 when the male stop is housed within the female stop, thereby increasing the sealing performance of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2 and reducing the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2.
[0069] In some embodiments, the first plug-in structure 12 includes a female stop provided on the first housing 1, and the second plug-in structure 22 includes a male stop provided on the end face around the opening of the second receiving groove 21. The male stop extends through the opening of the first receiving groove 11 into the first receiving groove 11, and the male stop is accommodated within the female stop.
[0070] When the male stop is placed inside the female stop, the male stop can cover the contact area between the end face around the opening of the first receiving groove 11 and the end face around the opening of the second receiving groove 21, thereby increasing the sealing of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2 and reducing the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2.
[0071] In some embodiments, the female stop is circumferentially arranged around the opening of the first receiving groove 11, and the male stop is circumferentially arranged around the end face around the opening of the second receiving groove 21. This allows the male stop to cover the entire contact area between the end faces around the openings of the first and second receiving grooves when the male stop is housed within the female stop, thereby increasing the sealing performance of the oil storage cavity 3 at the connection between the first housing 1 and the second housing 2, and reducing the risk of leakage of e-liquid from the connection between the first housing 1 and the second housing 2.
[0072] Please refer to Figure 3In some embodiments, the first housing 1 is provided with a first through hole 13, the second housing 2 is provided with a second through hole 23 corresponding to the first through hole 13, and the oil storage cotton 4 is provided with a third through hole 42, wherein one end of the third through hole 42 is connected to the first through hole 13, and the end of the third through hole 42 away from the first through hole 13 is connected to the second through hole 23. The first through hole 13, the third through hole 42 and the second through hole 23 are sequentially connected to form an airflow channel.
[0073] The airflow channel in the above embodiments is used to house the atomizing core and to allow airflow.
[0074] In some embodiments, the cartridge further includes a first seal and a second seal, the first seal blocking the first through hole 13 and the second seal blocking the second through hole 23.
[0075] By adopting the above technical solution, the first and second sealing components can seal the oil storage chamber 3, preventing leakage of e-liquid from the oil storage chamber 3 before the e-liquid cartridge is installed on the electronic atomizing device. The first and second sealing components can be removed when the e-liquid cartridge is installed on the electronic atomizing device.
[0076] This application provides an electronic atomizing device, including the e-cigarette cartridge of the first aspect embodiment described above.
[0077] By applying the e-cigarette cartridge of the first aspect embodiment to the electronic atomizing device, the component composition of the electronic atomizing device can be simplified, making the structure of the electronic atomizing device simpler and more compact, and saving the processing and assembly costs of the electronic atomizing device; and also reducing the risk of leakage of the electronic atomizing device.
[0078] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
