[0002] With the advent of atomizer products, there are more and more styles of atomizers on the market. In existing atomizers, there is usually a liquid inlet hole on the atomizing tube in the atomizing component, and the liquid is absorbed by the absorbent cotton in the atomizing component. The aerosol matrix in the liquid cup flows into the absorbent cotton through the liquid inlet hole. However, when the liquid level of the aerosol matrix in the liquid cup drops to more than half the position of the liquid inlet hole, it is necessary to add aerosol matrix. Otherwise, it will lead to problems such as dry burning and burnt coil, which will affect the service life.

[0003] Therefore, existing technology cannot meet our needs. Utility Model Content

[0004] The technical problem to be solved by the embodiments of this application is that when the liquid level of the aerosol matrix in the liquid cup of the existing atomizer drops to more than half the position of the oil inlet, it is necessary to add aerosol matrix. Otherwise, it will lead to problems such as dry burning and burnt coil, which will affect the service life.

[0005] To address the aforementioned technical problems, this application provides an atomizing core assembly, employing the following technical solution, including:

[0006] An atomizing core assembly includes: an atomizing tube and a heating element disposed within the atomizing tube. The atomizing tube has a first liquid inlet. The atomizing core assembly also includes a first tube body, which is sleeved outside the atomizing tube. A first gap is formed between the first tube body and the atomizing tube. The first tube body has at least one second liquid inlet, which communicates with the first liquid inlet through the first gap.

[0007] Furthermore, the width D of the first gap is 0.5-1mm.

[0008] Furthermore, the first tube body is also provided with at least one vent hole, which is located at the upper end of the second liquid inlet hole.

[0009] Furthermore, the atomizing core assembly also includes a first liquid storage component, which is sleeved outside the heating element and disposed inside the atomizing tube.

[0010] Furthermore, the atomizing core assembly also includes a bracket, which is sleeved outside the first liquid storage component. The bracket is provided with a third liquid inlet hole, which is connected to the first liquid inlet hole.

[0011] Furthermore, the third liquid inlet is configured as a second gap; in the axial direction of the bracket, the length of the second gap is greater than or equal to 1 / 3 of the length of the first liquid reservoir.

[0012] Furthermore, the atomizing core assembly also includes a second liquid reservoir, which is disposed between the bracket and the atomizing tube.

[0013] Furthermore, the atomizing core assembly also includes a first support member, which is provided with a first slot and a second slot. One end of the atomizing tube and one end of the bracket are fixed in the first slot, and one end of the first tube body is fixed in the second slot; and / or,

[0014] The atomizing tube is also provided with a sealing element, which has a third slot for the other end of the atomizing tube to be inserted into, and the other end of the first tube body is sleeved outside the sealing element.

[0015] To address the aforementioned technical problems, this application also provides an atomizer, which employs the following technical solution:

[0016] It includes a liquid cup and the atomizing core assembly, the atomizing core assembly being disposed inside the liquid cup, and the second liquid inlet being connected to the liquid cup.

[0019] Compared with the prior art, the embodiments of this application have the following advantages: By installing the first tube body outside the atomizing tube, a first gap is formed between the first tube body and the atomizing tube. Therefore, after the heating element consumes the aerosol matrix, a siphon effect is generated on the aerosol matrix, which can ensure that the supply rate of the aerosol matrix to the heating element and the atomization rate of the heating element are kept in balance, so that the user's taste quality experience is stable. At the same time, the aerosol matrix in the liquid cup can be completely absorbed by the siphon, so that the aerosol matrix does not need to be added when the liquid level of the aerosol matrix drops to a specific position, preventing the heating element from dry burning and the core from clogging, and extending the service life of the atomizing core assembly.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] Please see the appendix Figure 1 and attached Figure 4 ~Attached Figure 6 As shown, an atomizing core assembly includes: an atomizing tube 1 and a heating element 2 disposed within the atomizing tube 1. The atomizing tube 1 is provided with a first liquid inlet 11. The atomizing core assembly also includes a first tube body 3, which is sleeved outside the atomizing tube 1. A first gap 30 is formed between the first tube body 3 and the atomizing tube 1. The first tube body 3 is provided with at least one second liquid inlet 31, which communicates with the first liquid inlet 11 through the first gap 30. This application creates a first gap 30 between the first tube body 3 and the atomizing tube 1 by installing the first tube body 3 outside the atomizing tube 1. Therefore, after the heating element 2 consumes the aerosol matrix, it will produce a siphon effect on the aerosol matrix, which can ensure that the supply rate of the aerosol matrix to the heating element 2 and the atomization rate of the aerosol matrix by the heating element 2 are kept in balance, so that the user's taste quality experience is stable. At the same time, the aerosol matrix in the liquid cup can be completely absorbed by the siphon, so that the aerosol matrix does not need to be added when the liquid level of the aerosol matrix drops to a specific position, preventing the heating element 2 from dry burning and clogging, and extending the service life of the atomizing core assembly.

[0032] As attached Figure 1 As shown, in some embodiments, the width D of the first gap 30 is 0.5-1mm. Setting a suitable gap width improves the siphon effect, ensuring a balance between the supply rate of the aerosol matrix to the heating element 2 and the atomization rate of the aerosol matrix by the heating element 2. This provides a stable taste experience for the user. Simultaneously, the aerosol matrix in the liquid cup can be completely absorbed through siphoning, eliminating the need to add aerosol matrix when the liquid level drops to a specific position. This prevents the heating element 2 from dry burning and clogging, extending the service life of the atomizing core assembly.

[0033] It is understood that the width D of the first gap 30 is any value or any two values ​​formed by 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, and 1.0mm.

[0034] As attached Figure 1 and attached Figure 4 As shown, in some embodiments, the first tube 3 is further provided with at least one vent hole 32, which is located above the second liquid inlet 31. By providing the vent hole 32 on the first tube 3, when the liquid level of the aerosol matrix drops to the position between the vent hole 32 and the second liquid inlet 31, the vent hole 32 can promptly discharge the gas in the first gap 30, forming a "siphon liquid film" within the first gap 30. When the liquid volume is low, this facilitates pressure balance between the liquid chamber and the outside environment, thereby ensuring the aerosol matrix in the liquid cup is completely absorbed and atomized. This maintains a balance between the supply rate of the aerosol matrix to the heating element 2 and the atomization rate of the heating element 2, resulting in a stable user taste experience. It eliminates the need to add aerosol matrix when the liquid level drops to a specific position, preventing the heating element 2 from dry burning or scorching, and extending the service life of the atomizing core assembly.

[0035] Furthermore, the shapes of the first liquid inlet 11, the second liquid inlet 31, and the vent 32 can be the same or different. The first liquid inlet 11, the second liquid inlet 31, and the vent 32 can each be selected from shapes such as circular, square, or rectangular. The first liquid inlet 11 can also be inclined. The first tube body 3 is made of materials such as metal, plastic, or silicone.

[0036] To elaborate further, "upper end" refers to the position of the vent 32 above the second liquid inlet 31 when viewed directly from the atomizing core assembly. This means that the aerosol is released upwards after the atomizing core assembly forms the aerosol, and the vent 32 is positioned close to the mouthpiece. The vent 32 is primarily used to promptly expel the gas located between the vent 32 and the second liquid inlet 31 within the first gap 30.

[0037] As attached Figure 1As shown, in some embodiments, the atomizing core assembly further includes a first liquid storage component 4, which is sleeved outside the heating element 2 and disposed inside the atomizing tube 1. The first liquid storage component 4 stores a certain amount of aerosol matrix, and through its own capillary action or a specific liquid guiding structure, uniformly and stably supplies the aerosol matrix to the heating element 2, providing sufficient liquid supply for the atomization process. This ensures that the atomizing core assembly can continuously acquire aerosol matrix during operation, preventing the heating element 2 from dry burning or clogging, and extending the service life of the atomizing core assembly. Simultaneously, the first liquid storage component 4 can also firmly adsorb the aerosol matrix, reducing the fluidity and volatility of the aerosol matrix inside the atomizing core assembly, effectively preventing leakage of the aerosol matrix from the atomizing core assembly, and avoiding equipment damage, pollution, and impact on user experience caused by oil leakage.

[0038] As attached Figure 1 and attached Figure 6 As shown, in some embodiments, the atomizing core assembly further includes a bracket 5, which is sleeved on the first liquid reservoir 4. The bracket 5 has a third liquid inlet 51, which communicates with the first liquid inlet 11. The bracket 5 can support and fix the first liquid reservoir 4 and the heating element 2, ensuring that the atomizing core assembly maintains the correct position and shape during operation, preventing deformation or displacement of the first liquid reservoir 4 and the heating element 2 due to external forces or their own weight, and ensuring the safe use of the atomizer.

[0039] As attached Figure 1 and attached Figure 6 As shown, in some embodiments, the third liquid inlet 51 is configured as a second gap; in the axial direction of the support 5, the length of the second gap is greater than or equal to 1 / 3 of the length of the first liquid storage component 4. Directly using the third liquid inlet 51 as the second gap results in a simple structure and convenient setup. A siphon effect can also be formed within the second gap, giving the atomizer two siphonable gaps simultaneously, further improving the siphon effect and ensuring a stable taste experience for the user. Simultaneously, it can completely absorb and atomize the aerosol matrix in the liquid cup, eliminating the need to add aerosol matrix when the liquid level drops to a specific position, thus extending the service life of the atomizing core assembly.

[0040] Furthermore, the second gap is in the shape of a long groove, and the length of the second gap is greater than or equal to 1 / 3 of the length of the first liquid storage component 4, so as to form a stronger siphon effect and facilitate oil conduction.

[0041] As attached Figure 1As shown, in some embodiments, the atomizing core assembly further includes a second liquid reservoir 6, which is disposed between the support 5 and the atomizing tube 1. Adding the second liquid reservoir 6 not only allows for the storage of more aerosol matrix, but also works in conjunction with the first liquid reservoir 4, which is sleeved outside the heating element 2, to form a more stable liquid supply system. When the first liquid reservoir 4 consumes liquid due to atomization, the second liquid reservoir 6 can continuously replenish it, ensuring that the heating element 2 always has sufficient aerosol matrix for atomization and avoiding dry burning due to insufficient liquid supply.

[0042] Furthermore, the first liquid storage component 4 and the second liquid storage component 6 can be made of materials with liquid adsorption functions, such as fiber materials and porous materials; wherein, the fiber material can be plant fiber, animal fiber, mineral fiber, synthetic fiber, etc. Specifically, the materials of the first liquid storage component 4 and the second liquid storage component 6 can be cotton, non-woven fabric, glass fiber, porous ceramic material, and porous metal material, respectively.

[0043] As attached Figure 1 As shown, in some embodiments, the atomizing core assembly further includes a first support member 7, which is provided with a first slot 71 and a second slot 72. One end of the atomizing tube 1 and one end of the bracket 5 are fixed in the first slot 71, and one end of the first tube body 3 is fixed in the second slot 72. The first support member 7 provides a stable installation position for the bracket 5 and the first tube body 3, ensuring that the components within the atomizing core assembly maintain the correct position and shape during operation, preventing deformation or displacement of the first liquid reservoir 4 and the second liquid reservoir 6 due to external forces or their own weight, and ensuring the safe use of the atomizer.

[0044] As attached Figure 1 and attached Figure 5 As shown, in some embodiments, the atomizing tube 1 is further provided with a sealing element 8. The sealing element 8 is provided with a third slot 81 for the other end of the atomizing tube 1 to be inserted into, and the other end of the first tube body 3 is sleeved on the sealing element 8. The sealing element 8 can stabilize the other end of the atomizing tube 1, ensuring that the components inside the atomizing core assembly maintain the correct position and shape during operation, preventing deformation or displacement caused by external force or its own weight, and ensuring the safe use of the atomizer. At the same time, with the first support 7 and the sealing element 8 fixed, the atomizing core assembly is formed into a modular whole, which facilitates the disassembly, assembly and maintenance of the atomizing core assembly and improves production efficiency.

[0045] Based on the above-described atomizing core assembly, this application embodiment also provides an atomizer, which adopts the following technical solution:

[0046] As attached Figure 2 and attached Figure 3 As shown, an atomizer includes a liquid cup 9 and an atomizing core assembly, the atomizing core assembly being disposed within the liquid cup 9, and a second liquid inlet 31 communicating with the liquid cup 9.

[0047] This application creates a first gap 30 between the first tube body 3 and the atomizing tube 1 by installing the first tube body 3 outside the atomizing tube 1. Therefore, after the heating element 2 consumes the aerosol matrix, it will produce a siphon effect on the aerosol matrix, which can ensure that the supply rate of the aerosol matrix to the heating element 2 and the atomization rate of the aerosol matrix by the heating element 2 are kept in balance, so that the user's taste quality experience is stable. At the same time, the aerosol matrix in the liquid cup can be completely absorbed by the siphon, so that the aerosol matrix does not need to be added when the liquid level of the aerosol matrix drops to a specific position, preventing the heating element 2 from dry burning and clogging, and extending the service life of the atomizing core assembly.

[0048] Furthermore, the second liquid inlet 31 is located inside the liquid cup 9, and the liquid cup 9 is provided with an injection hole 91. After adding the first tube 3, the pressure on the liquid storage surface in the liquid cup 9 is reduced when injecting the aerosol matrix, avoiding the unpleasant experience of "pressure liquid" during injection. There is no need to use syringes or other devices to increase the injection pressure, making it convenient for the liquid cup 9 to be injected at normal pressure. At the same time, the "siphon" effect continues until the aerosol matrix in the liquid cup 9 is completely atomized, preventing the heating element 2 from dry burning and clogging, and extending the service life of the atomizing core assembly.

[0049] Furthermore, the shape of the first support member 7 can be adjusted according to the shape of the bottom of the liquid cup 9 so that the first support member 7 fits against the inner wall of the liquid cup 9, thereby sealing and forming an aerosol matrix cavity for the aerosol matrix to be contained.

[0050] Based on the atomizing core assembly and atomizer described above, this application also provides an aerosol generating device, which adopts the technical solution described below:

[0051] An aerosol generating device includes a battery assembly and the atomizer, wherein the battery assembly and the atomizer are detachably connected.

[0052] This application creates a first gap 30 between the first tube body 3 and the atomizing tube 1 by installing the first tube body 3 outside the atomizing tube 1. Therefore, after the heating element 2 consumes the aerosol matrix, it will produce a siphon effect on the aerosol matrix, which can ensure that the supply rate of the aerosol matrix to the heating element 2 and the atomization rate of the aerosol matrix by the heating element 2 are kept in balance, so that the user's taste quality experience is stable. At the same time, the aerosol matrix in the liquid cup can be completely absorbed by the siphon, so that the aerosol matrix does not need to be added when the liquid level of the aerosol matrix drops to a specific position, preventing the heating element 2 from dry burning and clogging, and extending the service life of the atomizing core assembly.
