Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a cartridge component and an aerosol generation system. Background Technology
[0002] In the e-cigarette industry, to meet users' needs for different flavored e-liquids or the lifespan of e-liquid cartridges, cartridges typically need to be replaced. Some existing cartridges are cumbersome to replace, reducing convenience and efficiency. Other cartridges have handles for easy handling, which improves convenience to some extent, but in practice, the handle's fixed end is prone to tearing when pulled to remove the cartridge, indicating poor durability. Furthermore, to maintain the overall structural integrity of the e-cigarette, the handle is usually attached to the cartridge surface, requiring prying it off before pulling, making it cumbersome. When the cartridge is tightly installed, the difficulty of prying off the handle increases further, making the operation time-consuming and laborious, potentially causing finger discomfort and a poor user experience. Utility Model Content
[0003] The purpose of this invention is to provide a cartridge assembly and an aerosol generation system, which can improve the ease of replacing the cartridge body and enhance the user experience.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] The e-cigarette cartridge assembly includes:
[0006] The cigarette cartridge itself;
[0007] A handle structure is provided on one surface of the cartridge body. The handle structure has a fixed end fixed to the surface of the cartridge body and a free section connected to the fixed end. A pressure line is provided on the side of the handle structure near the fixed end.
[0008] As a further technical solution, the anti-pressure line is set to one; or, the anti-pressure line is set to multiple, and the multiple anti-pressure lines are set to be relatively parallel and spaced apart.
[0009] As a further technical solution, the distance between the counter-pressure line and the fixed end is greater than or equal to 3mm.
[0010] As a further technical solution, the end face of the free segment facing away from the fixed end is an arc-shaped surface.
[0011] As a further technical solution, the handle structure is provided with a main body, which is bonded to the outer surface of the e-cigarette cartridge body, and the main body is also provided with a clearance groove.
[0012] The fixed end is connected to the inner wall of the clearance groove, and the free section is located in the clearance groove, and the free section is in a cantilever state in the clearance groove.
[0013] As a further technical solution, there is an avoidance gap between the outer periphery of the free segment and the inner wall of the avoidance groove.
[0014] As a further technical solution, the clearance is an equidistant clearance.
[0015] As a further technical solution, the width of the clearance is less than or equal to 2.5 mm.
[0016] As a further technical solution, a smooth transition portion is provided at the connection position between the fixed end and the inner wall of the clearance groove.
[0017] As a further technical solution, the fixed end is integrally formed with the main body.
[0018] An aerosol generation system includes a battery rod, a heating component, and a cartridge component.
[0019] Compared with the prior art, the technical advantages of the cigarette cartridge component and aerosol generation system provided by this utility model are as follows:
[0020] The handle structure has a fixed end fixed to the surface of the cartridge and a free section connected to the fixed end. Additionally, a pressure line is provided on the side of the handle structure near the fixed end. Therefore, when the cartridge needs to be replaced, the free section of the handle structure is bent away from the cartridge body. The handle structure bends along the pressure line, and then the cartridge body can be removed by pulling the handle structure. In this process, firstly, the handle structure makes it easier for the operator to pick up the cartridge body, thus improving the convenience and efficiency of cartridge replacement. Secondly, when the free section of the handle structure is bent away from the cartridge body, the handle structure bends along the pressure line, ensuring the bending accuracy of the handle structure. This reduces the probability of the fixed end of the handle structure tearing due to pulling; at the same time, the pressure line disperses the tensile force, thereby increasing the overall strength of the handle structure and further reducing the probability of tearing. Thirdly, by setting a counter-pressure line, the free section of the handle structure is prevented from being completely attached to the side wall of the cartridge body, thus making it easier for the operator to bend the free section of the handle structure, reducing discomfort to the operator's fingers, and improving the customer experience.

[0028] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.
[0029] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0030] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.
[0031] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation.

For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.
[0035] Combination Figures 1 to 4As shown, the cartridge assembly provided in this embodiment can improve the ease of replacing the cartridge body 110 and enhance the user experience. It should be noted that the cartridge assembly can be applied to an aerosol generating device. When the aerosol generating device activates its heating function, the heating component of the aerosol generating device can heat the cartridge assembly, which then generates aerosol for the user to inhale. After the aerosol generating device completes one heating process, the cartridge assembly is consumed as a consumable and can then be replaced.
[0036] Specifically, the cartridge assembly includes a cartridge body 110 and a handle structure 120. The handle structure 120 can pull the cartridge body 110. For example, when it is necessary to replace the cartridge assembly in the aerosol generating device, the handle structure 120 can be pulled to remove the cartridge assembly from the aerosol generating device. The handle structure 120 is disposed on one surface of the cartridge body 110. The handle structure 120 is provided with a fixed end 122 fixed to the surface of the cartridge body 110 and a free section 123 connected to the fixed end 122. A pressure line 121 is provided on the side of the handle structure 120 near the fixed end 122.
[0037] The handle structure 120 has a fixed end 122 fixedly disposed on the surface of the cartridge body 110 and a free section 123 connected to the fixed end 122; at the same time, a counter-pressure line 121 is provided on the side of the handle structure 120 near the fixed end 122. Therefore, when it is necessary to replace the cartridge body 110, the free section 123 of the handle structure 120 is bent in the direction away from the cartridge body 110, the handle structure 120 is bent along the counter-pressure line 121, and then the cartridge body 110 can be removed by pulling the handle structure 120. In this process, on the one hand, by setting the handle structure 120, it is convenient for the operator to pick up the cartridge body 110, thereby improving the convenience and efficiency of replacing the cartridge body 110. Secondly, when the free segment 123 of the handle structure 120 is bent away from the cartridge body 110, the handle structure 120 is bent along the anti-pressure line 121, ensuring the bending accuracy of the handle structure 120. This reduces the probability of the fixed end 122 of the handle structure 120 tearing due to pulling. At the same time, the anti-pressure line 121 can disperse the tension, thereby increasing the overall strength of the handle structure 120 and further reducing the probability of tearing. Thirdly, by setting the anti-pressure line 121, the free segment 123 of the handle structure 120 is prevented from being completely attached to the side wall of the cartridge body 110. This makes it easier for the operator to bend the free segment 123 of the handle structure 120, reducing discomfort to the operator's fingers and improving the customer experience.
[0038] In this embodiment, for ease of description, reference is made to... Figure 1The structure and principle are explained using the example of a handle structure 120 set on the upper surface of the cartridge body 110.
[0039] In this embodiment, the anti-pressure line 121 is set as one. In other embodiments, multiple anti-pressure lines 121 may be provided, and the multiple anti-pressure lines 121 are arranged relatively parallel and spaced apart to further improve the convenience of bending the handle structure 120 along the anti-pressure line 121.
[0040] When the free segment 123 of the handle structure 120 is bent away from the cartridge body 110, in order to further improve the convenience and bending accuracy of the handle structure 120 being bent along the anti-pressure line 121, in this embodiment, the anti-pressure line 121 passes through the handle structure 120 in the Y direction.
[0041] Preferably, the distance between the counter-pressure line 121 and the fixed end 122 is greater than 0.5 mm.
[0042] In this embodiment, the distance between the pressure line 121 and the fixed end 122 is set to be greater than or equal to 0.5 mm. However, it is important to avoid an excessively large distance between the pressure line 121 and the fixed end 122. If the distance is too large, for example, 15 mm, the handle structure 120 may bend along the pressure line 121. During the process of pulling the handle structure 120 to remove the cartridge body 110 from the electronic cigarette casing, the fixed end 122 of the handle structure 120 may bend again, thereby increasing the probability of the handle structure 120 being torn. The specific value is not limited. In other embodiments, the distance between the pressure line 121 and the fixed end 122 can be adjusted adaptively according to actual needs, and is not limited to the greater than or equal to 0.5 mm in this embodiment.
[0043] In addition, in this embodiment, the width of the anti-pressure line 121 is set to 0.1mm to 0.3mm. In other embodiments, the width of the anti-pressure line 121 can be adjusted according to actual needs, and is not limited to this embodiment.
[0044] Furthermore, the handle structure 120 is symmetrically arranged about the centerline of the cartridge body 110 along the X direction.
[0045] Combination Figure 1 and Figure 2 As shown, with this configuration, since the handle structure 120 is located on the upper surface of the cartridge body 110 and in the middle of the upper surface of the cartridge body 110, the process of pulling the handle structure 120 to remove the cartridge body 110 can ensure that the handle structure 120 and the cartridge body 110 are subjected to uniform force, reducing the probability of the handle structure 120 breaking or the cartridge body 110 being obstructed from being removed, thereby further improving the convenience of replacing the cartridge body 110.
[0046] Preferably, the end face of the handle structure 120 facing away from the fixed end 122 is set as an arc-shaped surface. This design prevents the free segment 123 of the handle structure 120 from scratching the operator's fingers due to sharp parts during the process of turning it, thereby further improving the user experience. In addition, in this embodiment, the center of the arc-shaped surface is set on the centerline of the handle structure 120 along the X direction.
[0047] Furthermore, the handle structure 120 is provided with a body part 130, which is bonded to the outer surface of the cartridge body 110. The body part 130 also has a relief groove 131. The fixed end 122 is connected to the inner wall of the relief groove 131, and the free section 123 is located in the relief groove 131, which is in a cantilever state within the relief groove 131.
[0048] In this embodiment, the main body 130 is configured as a sticker, combined with Figure 1 As shown, by covering the cartridge body 110 with a sticker, firstly, the sticker can protect the surface of the cartridge body 110, effectively preventing scratches, abrasions, and wear caused by contact with other objects during transportation, storage, and use, thus maintaining the integrity and aesthetics of the cartridge body 110's appearance; it also provides waterproof, moisture-proof, and dustproof effects, ensuring the performance and taste of the cartridge body 110; and by fitting the sticker to the opening of the cartridge body 110, it can effectively prevent e-liquid from leaking from the connection between the cartridge body 110 and the e-cigarette device or other possible gaps. Secondly, the sticker can enhance the aesthetics and visual appeal of the cartridge body 110 by adding patterns, and can also be printed with text to distinguish the flavor, specifications, brand, etc. of the cartridge body 110, making it convenient for users to quickly identify and select the target cartridge body 110. Thirdly, when replacing the cartridge 110, the sticker can prevent users' fingers from directly contacting the surface of the cartridge 110, preventing contamination of the cartridge 110 due to oil, dirt, etc. on the fingers. At the same time, it can also keep the user's fingers clean when replacing the cartridge 110, thereby further improving the user experience.
[0049] In this embodiment, the free segment 123 is disposed within the clearance groove 131. This ensures the effectiveness of the sticker and the free segment 123 itself while preventing the thickness of the cartridge body 110 from increasing due to the free segment 123 being disposed on the sticker. This improves the installation stability and ease of installation of the cartridge body 110 and ensures the rationality of the internal structure of the electronic cigarette. At the same time, since the free segment 123 is in a cantilever state within the clearance groove 131, it can prevent the free segment 123 from being completely attached to the side wall of the cartridge body 110. This further facilitates the operator in bending the free segment 123 of the handle structure 120, reduces discomfort to the operator's fingers, and thus improves the customer experience.
[0050] To further reduce the manufacturing difficulty of the cartridge components and enhance the structural strength of the handle structure 120, in this embodiment, the handle structure 120 is integrally molded. In other embodiments, the free segment 123 and the sticker can be separate.
[0051] Combination Figures 1 to 3 As shown, in order to further improve the convenience of turning the handle structure 120 when the free segment 123 of the handle structure 120 is turned away from the cartridge body 110, in this embodiment, a clearance gap 140 is provided between the outer periphery of the free segment 123 and the inner wall of the clearance groove 131. Specifically, along the Z direction, the cross-sectional area of the handle structure 120 is smaller than the cross-sectional area of the clearance groove 131, so that a clearance gap 140 is formed between the side wall of the handle structure 120 and the clearance groove 131. When the free segment 123 of the handle structure 120 is turned, the clearance gap 140 provides clearance space for the operator's fingers.
[0052] Furthermore, in this embodiment, for improved ease of operation, during the bending of the handle structure 120 along the anti-pressure line 121, the clearance gap 140 is an equidistant gap. That is, during the bending of the handle structure 120, the clearance space at all points on the outer periphery of the free segment 123 is equal, allowing the operator to bend the handle structure 120 from any position, thereby further enhancing the user experience.
[0053] Preferably, the width of the clearance 140 is less than or equal to 2.5 mm.
[0054] When the width of the clearance 140 is too large, for example, H is 10mm, if the size of the clearance groove 131 remains unchanged, the size of the handle structure 120 will be reduced, thus compromising the structural strength of the handle structure 120. This could lead to breakage of the handle structure 120 when replacing the cartridge body 110. Conversely, if the size of the handle structure 120 remains unchanged, the clearance groove 131 will increase, reducing the effective coverage area of the sticker on the cartridge body 110, thus affecting the sticker's performance. Furthermore, an excessively large clearance 140 increases the probability of dirt and dust accumulating within it, affecting the performance of the cartridge assembly and the user experience. In this embodiment, the width of the clearance 140 is less than or equal to 2.5mm. In other embodiments, the width of the clearance 140 can be adjusted adaptively according to actual needs, and is not limited to this embodiment.
[0055] Preferably, the clearance 140 is provided as a smooth transition section on the side near the fixed end 122 of the handle structure 120.
[0056] Combination Figure 3As shown, in this embodiment, the handle structure 120 has a horseshoe-shaped cross-section in the Z direction, and correspondingly, the clearance gap 140 has a U-shaped cross-section. To improve the structural strength between the fixed end 122 of the handle structure 120 and the body 130, both ends of the clearance gap 140 are set as smooth transition portions. This design avoids tearing gaps at the fixed end 122 of the handle structure 120, thereby improving the structural strength between the handle structure 120 and the body 130, and further reducing the probability of tearing of the fixed end 122 of the handle structure 120 due to pulling.
[0057] In this embodiment, there are no specific restrictions on the material of the handle structure 120, the specific specifications of the cartridge body 110 and the handle structure 120, etc., which can be adapted to actual production needs or market usage needs.
[0058] The aerosol generation system includes a battery rod, a heating element, and a cartridge assembly. The battery rod, heating element, and cartridge assembly are arranged sequentially from top to bottom. Specific structural details are based on existing technology and will not be elaborated here.
[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
