Description

Technical Field

[0001] This application relates to the field of aerosol generating device technology, and more specifically, to a liquid bullet structure and an aerosol generating device. Background Technology

[0002] Aerosol generating devices typically consist of a liquid cartridge structure and a support structure. The liquid cartridge structure houses an atomizing core assembly, which heats the aerosol generating medium to produce an aerosol for the user to inhale. The support structure contains a liquid reservoir to hold the aerosol generating medium.

The atomizer core assembly is located inside the liquid cup, and the bottom cap is positioned on the side of the liquid cup furthest from the nozzle, serving to support the atomizer core assembly and facilitate airflow. After the aerosol generating medium enters the atomizer core assembly, or after the aerosol condenses and flows back into the liquid cup, poor sealing between the liquid cup and the bottom cap can easily lead to leakage of the aerosol generating medium into the circuit components, thereby affecting the service life of the aerosol generating device.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0033] In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or operating state, specifically the orientation shown in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "comprising" means "including but not limited to". The terms first, second, third, etc., are used merely as illustrative purposes and do not impose numerical requirements or establish a numerical order.

[0036] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range.

Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0037] To solve the above problems, please refer to... Figures 1-2 This application provides a liquid bullet structure, which includes: an atomizing core assembly; a liquid cup 1000, the liquid cup 1000 having a first receiving cavity 1200 for receiving the atomizing core assembly; and a first sealing member 2000, the first sealing member 2000 including a sealing member body and an annular protrusion 2300, the annular protrusion 2300 being disposed on the outer side wall of the sealing member body, dividing the sealing member body into a first end 2100 and a second end 2200, the first end 2100 being provided with a vent hole 2400, the vent hole 2400 connecting the first end 2100 and the second end 2200;

[0038] The bottom cover 3000 has a second receiving cavity 3100. The first end 2100 is located in the first receiving cavity 1200, and the second end 2200 is located in the second receiving cavity 3100. The liquid cup 1000 and the bottom cover 3000 together hold the annular protrusion 2300, which seals the first receiving cavity 1200 and the second receiving cavity 3100.

[0039] In this embodiment, the first end 2100 and the second end 2200 respectively enter the first receiving cavity 1200 and the second receiving cavity 3100 to block the first receiving cavity 1200 and the second receiving cavity 3100, so as to prevent liquid leakage between the liquid cup 1000 and the bottom cover 3000; the annular protrusion 2300 is disposed between the liquid cup 1000 and the bottom cover 3000, so it can further prevent liquid leakage between the liquid cup 1000 and the bottom cover 3000; at the same time, the annular protrusion 2300 can also abut against the liquid cup 1000 and the bottom cover 3000 to prevent the first sealing member 2000 from entering the first receiving cavity 1200 and the second receiving cavity 3100 too much, thereby improving the assembly efficiency and assembly accuracy of the liquid spring structure.

[0040] In summary, the liquid bullet structure of this embodiment has high assembly efficiency and service life, therefore the aerosol generating device also has high assembly efficiency and service life.

[0041] Further, please refer to Figure 1 The bottom cover 3000 has two opposite outer side walls with first buckles 3200. The first receiving cavity 1200 has two buckle mounting protrusions 1300 at the opening 42 facing the bottom cover 3000. The inner side wall of the buckle mounting protrusion 1300 has a first buckle groove 1400. The first buckles 3200 and the first buckle grooves 1400 are engaged one-to-one to connect the liquid cup 1000 and the bottom cover 3000.

[0042] In this embodiment, when the liquid cup 1000 and the bottom cover 3000 are connected, the snap-fit ​​protrusion 1300 will abut against the side wall of the bottom cover 3000, and the first snap-fit ​​groove 1400 on the snap-fit ​​protrusion 1300 will engage with the first snap 3200 to prevent the liquid cup 1000 and the bottom cover 3000 from separating.

[0043] It should be understood that the annular protrusion 2300 may be provided with a third clearance hole 2310, and the snap-fit ​​mounting protrusion 1300 passes through the third clearance hole 2310 to avoid the snap-fit ​​mounting protrusion 1300 squeezing the annular protrusion 2300 and causing the first seal 2000 to deform, thereby avoiding the failure of the first seal 2000 to seal; at the same time, it can also allow the first seal 2000 and the liquid cup 1000 to be assembled first, and then modularly installed on the bottom cover 3000, thereby improving the assembly efficiency of the liquid spring structure.

[0044] Further, please refer to Figures 1-2 The length direction of the first receiving cavity 1200 intersects the length direction of the second receiving cavity 3100 to form an angle of 85° to 95°.

[0045] In this embodiment, the length direction of the first receiving cavity 1200 is the Z direction in the figure, and the length direction of the second receiving cavity 3100 is the X direction in the figure. Because the length directions of the first receiving cavity 1200 and the second receiving cavity 3100 form an angle of 85° to 95°, the liquid, after dripping down from the first receiving cavity 1200, will first contact the side wall of the second receiving cavity 3100 (or, if a first liquid-absorbing element is provided, it will drip onto the first liquid-absorbing element), thereby preventing the liquid in the first receiving cavity 1200 from flowing back directly through the second receiving cavity 3100 to other internal components (e.g., through the third sealing element 9000 for the opening through which gas flows through the microphone).

[0046] Further, please refer to Figure 2 and Figure 3 The bottom cover 3000 is provided with a first air inlet 8300 at one end away from the first receiving cavity 1200. The liquid bullet structure also includes a first liquid suction member, which is disposed in the second receiving cavity 3100. The first liquid suction member is provided with a first air passage 7100 and a second air passage 7200. The first air passage 7100 connects the second air passage 7200 and the first air inlet 8300. The second air passage 7200 is disposed along the length of the second receiving cavity 3100 and connects to the vent 2400.

[0047] In this embodiment, the first suction element can absorb the aerosol generating medium or other liquids flowing back from the first receiving cavity 1200 to the second receiving cavity 3100. The first air inlet 8300 is located at the end away from the first receiving cavity 1200 (Z direction), which can prevent the user from blocking the first air inlet 8300 when gripping the liquid bullet structure, thus affecting the user's suction experience. The second air passage 7200 is arranged along the X direction in the figure, which can allow the gas flowing from the first air passage 7100 into the second air passage 7200 to flow smoothly into the vent 2400, while the first air passage 7100 can guide the gas outside the first air inlet 8300 into the liquid bullet structure. When the length directions of the first air passage 7100 and the second air passage 7200 intersect to form an angle, it can also prevent the liquid flowing back in the second air passage 7200 from directly entering the first air passage 7100, but instead allow the liquid flowing back to contact the first suction element, so as to avoid the liquid blocking the first air inlet 8300.

[0048] It should be understood that the liquid atomizer structure may also be equipped with a suction nozzle 5000, located at the end furthest from the liquid cup 1000 and the second receiving cavity 3100, for drawing aerosol generating medium from the atomizing core assembly. A third liquid-absorbing component 30 may also be provided between the suction nozzle 5000 and the liquid cup 1000 to prevent leakage at the connection between the suction nozzle 5000 and the liquid cup 1000. The angles of the first air passage 7100 and the second air passage 7200 can be arbitrarily set to accommodate the vent 2400 and the first air inlet 8300 in different positions. For example, the first air passage 7100 and the second air passage 7200 may form a V-shape or be set at a right angle (e.g., Figure 3 ).

[0049] Further, please refer to Figure 2 and Figure 3 The liquid-bomb structure also includes a second sealing element 8100 and an air regulating element 8200. The second receiving cavity 3100 includes a first sub-receiving cavity and a second sub-receiving cavity. The first sub-receiving cavity and the second sub-receiving cavity are arranged sequentially along the length direction of the first air passage 7100. The first liquid suction element is located in the first sub-receiving cavity, the second sealing element 8100 is located in the second sub-receiving cavity, and the first air inlet 8300 penetrates the second sealing element 8100.

[0050] The air regulating component 8200 is disposed inside the bottom cover 3000 and is located between the second seal 8100 and the inner wall of the bottom cover 3000. The air regulating component 8200 is used to rotate or move so that the first air inlet 8300 is opened or closed.

[0051] In this embodiment, the second seal 8100 prevents liquid in the first liquid-absorbing element from seeping into the gas regulating element 8200. The gas regulating element 8200 can control the opening and closing of the first air inlet 8300 to prevent gas from entering the aerosol generating device when it is not in use, thereby preventing the microphone from being accidentally activated by airflow.

[0052] Further, please refer to Figure 2 and Figure 4 The liquid-elastic structure also includes a third seal 9000, which is used to seal the end of the second receiving cavity 3100 away from the first seal 2000. The side of the third seal 9000 away from the second receiving cavity 3100 is provided with a first electrode hole 9200 and a wire hole 9100. The atomizing core assembly includes a heating wire 22 and an atomizing core 21. One end of the heating wire 22 is connected to the atomizing core 21, and the other end passes through the wire hole 9100 and is bent into the first electrode hole 9200.

[0053] In this embodiment, the third sealing element 9000 can effectively seal the second receiving cavity 3100 (excluding the vent 2400 and the air passage used by the microphone) together with the first sealing element 2000 to prevent liquid from seeping out of the second receiving cavity 3100. The wire hole 9100 can restrict the heating wire 22 to prevent the heating wire 22 from bending under force and affecting the efficiency of the atomizing core assembly; at the same time, the wire hole 9100 can also guide the heating wire 22 into the first electrode hole 9200 with a shorter distance, thereby reducing the material signal of the heating wire 22. When the heating wire 22 is located in the first electrode hole 9200, the external electrode pin only needs to be inserted into the first electrode hole 9200 to assemble the electrode pin and the heating wire 22, thereby omitting the alignment step of the heating wire 22 and the electrode pin, and thus improving the assembly efficiency of the heating wire 22 and the motor.

[0054] Further, please refer to Figures 2-4 The third seal 9000 is also provided with a microphone hole 9300, which connects the second receiving cavity 3100 to the external environment; and / or,

[0055] The liquid cup 1000 is also provided with a liquid inlet 10, which is located on the outer wall of the liquid cup 1000 and connects the inside of the atomizing core assembly with the external environment.

[0056] In this embodiment, the microphone orifice guides the gas in the second receiving cavity 3100 through the microphone orifice to reach the microphone inside the aerosol generating device. The liquid inlet 10 guides the aerosol generating medium inside the aerosol generating device into the atomizing core assembly, and at the same time, it also strengthens the connection between the liquid bullet structure and the external structure.

[0057] Further, please refer to Figure 2 The vent 2400 includes a first sub-vent and a second sub-vent. The second sub-vent is located at the second end 2200. A second liquid suction element is provided inside the second sub-vent. The second liquid suction element is provided with a first through hole. The first through hole connects the first sub-vent and the second receiving cavity 3100.

[0058] In this embodiment, the second liquid suction member can further prevent the liquid in the second receiving cavity 3100 from leaking from the connection between the bottom cover 3000 and the first seal 2000. At the same time, it can also absorb the liquid flowing back into the second receiving cavity 3100 from the first sub-vent hole, so as to avoid excessive liquid in the second receiving cavity 3100 and leakage.

[0059] Further, please refer to Figure 4 and Figure 5The liquid bullet structure also includes a housing 4000, with the liquid cup 1000 and the bottom cover 3000 both disposed within the housing 4000. The inner sidewall of the housing 4000 is provided with two symmetrically arranged L-shaped guide grooves 4200 and a T-shaped protrusion 4100 formed between the two L-shaped guide grooves 4200. The outer sidewall of the liquid cup 1000 is provided with two symmetrically arranged L-shaped protrusions 1100 and a T-shaped groove 1110 formed between the two L-shaped protrusions 1100. The L-shaped protrusions 1100 correspond to the L-shaped guide grooves 4200, and the T-shaped groove 1110 corresponds to the T-shaped protrusions 4100.

[0060] In this embodiment, firstly, the T-shaped protrusion 4100 is embedded in the T-shaped groove 1110 formed by the two L-shaped protrusions 1100 on the outer wall of the liquid cup 1000, providing a clear and unique axial sliding path for the liquid cup 1000 to be inserted into the outer casing 4000. This effectively guides the liquid cup 1000 smoothly and accurately into the predetermined installation position, significantly improving assembly efficiency and accuracy. Secondly, the T-shaped groove 1110 constrains the spatial position of the T-shaped protrusion 4100, effectively limiting its axial movement and wobbling after the liquid cup 1000 is assembled in place. This enhances the structural stability and connection reliability of the liquid cup 1000 within the outer casing 4000, preventing loosening during operation.
