[0013] In some embodiments, an inner side of the assembly groove is provided with a connecting groove, the connecting groove being adapted for the connecting part to be inserted therein to restrict movement of the connecting part.
[0014] In some embodiments, the power supply terminal is an elastic contact terminal, the elastic contact terminal being configured to apply a force on the base and the atomization core that causes the base and the atomization core to move away from each other.

The term "based on" means "based at least in part on" . The terms "an example embodiment" and "one embodiment" mean "at least one example embodiment" .

[0028] As mentioned above, in a conventional electronic atomization apparatus, the heating assembly includes a sheet-like atomization core and a support member, etc. During the stacking and assembly process, the atomization core and the support member are prone to positional offset, which may affect the sealing effect of the sealing member.
[0029] Embodiments of the present disclosure provide an atomization heating assembly 10, an atomization core assembly 100, and an atomization apparatus. The atomization heating assembly 10 includes an atomization core 11 and a fixing member 13. The fixing member 13 includes a circumferential wall 132, which is arranged to define, in a circumferential direction, a limiting groove for accommodating and fixing the atomization core 11. An inner side wall of the limiting groove abuts against the atomization core 11 to prevent the atomization core 11 from being offset. The atomization heating assembly 10 is assembled as a whole, so the atomization core 11 will not experience positional offset during the assembly process, which can avoid affecting the sealing effect of the sealing member 30. The principles of the present disclosure will now be described in detail with reference to FIG. 1 to FIG. 6.
[0030] As shown in FIG. 1 to FIG. 4, the atomization heating assembly 10 includes an atomization core 11 and a fixing member 13. The atomization core 11 is adapted to heat an aerosol precursor to form an aerosol. The fixing member 13 is used to fix the atomization core 11 to the atomization apparatus and includes a circumferential wall 132. The circumferential wall 132 is arranged to define, in a circumferential direction, a limiting groove for accommodating and fixing the atomization core 11, and an inner side wall of the limiting groove abuts against the atomization core 11 to prevent the atomization core 11 from being offset. The fixing member 13 also includes a power supply opening, which is formed at an end of the circumferential wall 132 away from a precursor chamber for accommodating the aerosol precursor, to allow the atomization core 11 to be placed in the limiting groove via the power supply opening. The power supply opening is adapted for a power supply terminal 40 to pass through and to be electrically connected to an electrode of the atomization core 11. The power supply opening is also an opening for placing the atomization core in the limiting groove.
[0031] The fixing member 13 also includes a liquid inlet end 131. The liquid inlet end 131 is formed at the end of the circumferential wall 132 away from the power supply opening to prevent further movement of the atomization core 11 toward the precursor chamber. The liquid inlet end 131 has a liquid inlet port 1311 adapted for the aerosol precursor to enter the limiting groove, allowing the aerosol precursor to enter the limiting groove and contact the atomization core 11.
[0032] As shown in FIG. 1 to FIG. 4, the atomization core 11 and the fixing member 13 constitute an integral unit that can convert the aerosol precursor into an inhalable aerosol. The aerosol precursor refers to a substance that is converted into an inhalable aerosol upon heating, and may include e-liquid, glycerin, propylene glycol, nicotine, and flavorings, etc. The atomization core 11 can generate heat when energized; it heats up and atomizes the aerosol precursor it contacts, thereby forming an aerosol. The fixing member 13 can fix the atomization core 11 and keep it in a normal operating state. The fixing member 13 includes a circumferential wall 132, which is provided around the atomization core 11 and serves to support and position it. The circumferential wall 132 internally defines a limiting groove, the shape and size of which are adapted to the outer shape of the atomization core 11, allowing the atomization core 11 to be precisely embedded within the limiting groove.
[0033] With the above arrangement, the inner side wall of the limiting groove is in close contact with the atomization core 11, which can prevent the atomization core 11 from being displaced due to vibration or other reasons during assembly and use, ensuring a stable and effective heating process. At the same time, and more importantly, the heat from the atomization core 11 can also be transferred to the fixing member 13, so that the fixing member 13 can preheat the aerosol precursor. A power supply opening is provided at one end of the circumferential wall 132 away from the precursor chamber (i.e., the space for storing the aerosol precursor) , and the atomization core 11 can be inserted into the limiting groove from the power supply opening for installation.
[0034] The power supply opening allows a power supply terminal 40 (such as an electrode on a battery or power module) to pass through, thereby establishing an electrical connection with the electrode 111 on the atomization core 11 to provide power for the heating operation of the atomization core 11. A liquid inlet end 131 is provided at the end of the circumferential wall 132 opposite the power supply opening, and a liquid inlet port 1311 is provided on the liquid inlet end 131. The aerosol precursor can enter the limiting groove from the liquid inlet port 1311 and contact the atomization core 11. The presence of the liquid inlet port 1311 allows the aerosol precursor to be supplied smoothly and in appropriate amounts to the vicinity of the atomization core 11, so that the atomization core 11 can efficiently convert it into an aerosol. At the same time, the liquid inlet end 131 also serves to restrict excessive movement of the atomization core 11 toward the precursor chamber, maintaining the stability of the internal structure of the entire atomization heating assembly 10.
[0035] In addition, as mentioned earlier, the heat from the atomization core 11 can be transferred to the liquid inlet end 131 via the circumferential wall 132. The heated liquid inlet end 131 and circumferential wall 132 can preheat the aerosol precursor, which facilitates the smooth passage of the aerosol precursor through the micropores in the atomization core 11 in low-temperature environments or for highly viscous aerosol precursors, and further facilitates the atomization of the aerosol precursor.
[0036] With the above arrangement, the atomization core 11 is responsible for the heating and atomization of the aerosol precursor, while the fixing member 13 achieves the positioning, stable power supply, and effective delivery and preheating of the aerosol precursor through the limiting groove, the power supply opening, and the liquid inlet end 131. Before assembling the atomization core 11 into the atomization core assembly 100, the atomization core 11 can be placed into the limiting groove of the fixing member 13 along the power supply opening, and the atomization core 11 and the fixing member 13 form an integral atomization heating assembly 10. In the atomization heating assembly 10, the inner side wall of the limiting groove abuts against the atomization core 11, which can prevent positional offset of the atomization core 11 while preheating the aerosol precursor. The atomization heating assembly 10 as a whole is assembled with the sealing member 30 of the atomization core assembly 100, so the atomization core 11 will not experience positional offset during the assembly process, which can avoid affecting the sealing effect of the sealing member 30.
[0037] In some embodiments, as shown in FIG. 1 and FIG. 2, the atomization heating assembly 10 further includes a flow-stabilizing member 12. The flow-stabilizing member 12 is arranged in the limiting groove and located between the liquid inlet end 131 and the atomization core 11.
[0038] As shown in FIG. 1 and FIG. 2, a flow-stabilizing member 12 is provided between the liquid inlet end 131 and the atomization core 11. The flow-stabilizing member 12 can ensure that the aerosol precursor flows to the atomization core 11 at a uniform and stable rate, avoiding instantaneous overly concentrated or overly diluted atomization effects caused by uneven liquid supply. A stable liquid supply is beneficial for the atomization core 11 to continuously and uniformly vaporize the aerosol precursor, producing an aerosol of consistent quality, which can enhance the user's taste experience.
[0039] Secondly, during the atomization process, if the aerosol precursor directly impacts the atomization core 11, it may cause splashing of droplets, leading to local overheating, scorching, or an unpleasant taste. The flow-stabilizing member 12 reduces splashing by guiding the liquid to contact the heating surface gently and orderly, ensuring a clean and efficient atomization process. Furthermore, the flow-stabilizing member 12 indirectly affects the humidity of the generated aerosol (i.e., the ratio of vapor to droplets) by adjusting the contact area, contact method, or flow rate of the aerosol precursor with the atomization core 11. This can meet the user's demand for vapor fullness and can avoid discomfort in the mouth and nose or condensation problems caused by excessively high humidity.
[0040] In some embodiments, the flow-stabilizing member 12 includes at least one of a flow-stabilizing cotton, ceramic channels, a metal mesh, or a bellows. When the flow-stabilizing member 12 is flow-stabilizing cotton, the flow-stabilizing cotton is in close contact with the atomization core 11, absorbing and storing the aerosol precursor through the capillary action of the cotton fibers, and then gradually releasing it to the heating surface. A cotton flow-stabilizing member 12 can effectively control the liquid supply speed, prevent droplet splashing, and to some extent filter out large particulate impurities in the aerosol precursor. When the flow-stabilizing member 12 is ceramic channels, the microporous structure inside the ceramic forms a complex network of flow channels, and the aerosol precursor slowly diffuses through the channels and contacts the atomization core 11 through the channel walls.
[0041] A ceramic flow-stabilizing member 12 has good thermal stability, corrosion resistance, and can precisely control the distribution of the aerosol precursor. When the flow-stabilizing member 12 is a metal mesh, the mesh openings of the metal mesh restrict the speed at which the liquid drips directly, causing the aerosol precursor to be evenly distributed on the mesh surface before heating, and then slowly evaporating. A metal mesh has a simple structure and low cost. When the flow-stabilizing member 12 is a bellows, the bellows structure achieves flow stabilization by changing the liquid flow path to increase its contact time and area with the heating surface.
[0042] In some embodiments, as shown in FIG. 3 and FIG. 4, the fixing member 13 is an integrally formed metal part. A metal part is beneficial for transferring the heat from the atomization core 11 via the circumferential wall 132 to the liquid inlet end 131 to preheat the aerosol precursor.
[0043] As shown in FIG. 3 and FIG. 4, the fixing member 13 is a structure made of metal material through a single processing step (such as casting, stamping, forging, injection molding, etc. ) . With this arrangement, the fixing member 13 has better mechanical strength and durability while improving heat transfer efficiency because it has no seams or welding points. Secondly, the integrated structure reduces potential leakage paths. For the atomization core assembly 100, which needs to maintain a sealed internal environment, this helps to improve the sealing of the aerosol precursor and prevent external contaminants from entering.
[0044] At the same time, as mentioned earlier, when the atomization core 11 is operating, the heat it generates is first transferred to the circumferential wall 132, which is in close contact with it, and then the heat is transferred to the liquid inlet end 131 through the circumferential wall 132. When the atomization heating assembly 10 is assembled into the atomization core assembly 100, the liquid inlet end 131 is in contact with the aerosol precursor. Before the aerosol precursor start contacting the atomization core 11 for evaporation and atomization, it first undergoes a preheating process. Preheating can reduce the viscosity of the aerosol precursor, making it easier to be absorbed by the flow-stabilizing member 12 and the heating surface and to enter and pass through the micropores of the atomization core 11, which helps to improve atomization efficiency and avoid a large amount of instantaneous condensation or insufficient atomization caused by an overly cold aerosol precursor.
[0045] In some embodiments, as shown in FIG. 1, a side of the atomization core 11 facing away from the liquid inlet end 131 is flush with the power supply opening.
[0046] As shown in FIG. 1, the atomization core 11 has a sheet-like structure and has two opposing sides. One side of the atomization core 11 is in close contact with the flow-stabilizing member 12 for receiving and heating the atomizing medium transferred by the flow-stabilizing member 12. The other side of the atomization core 11 can be electrically connected to the power supply terminal 40.
[0047] In embodiments of the present disclosure, the side of the atomization core 11 facing away from the liquid inlet end 131 is flush with the power supply opening. With this arrangement, the entire side of the atomization core 11 is in contact with the circumferential wall 132 of the fixing member 13. The heat of the atomization core 11 can be quickly transferred to the circumferential wall 132 through the contact surface, and then diffuse to the liquid inlet end 131 through the circumferential wall 132. This helps to reduce heat loss, improve thermal energy utilization efficiency, and ensure the efficient progress of the atomization process.
[0048] In some embodiments, as shown in FIG. 3 and FIG. 4, the liquid inlet end 131 also includes a separating part 1312. The separating part 1312 is disposed within the liquid inlet port 1311 and can separate the liquid inlet port 1311 into a plurality of regions for supplying the aerosol precursor into the limiting groove.
[0049] As shown in FIG. 3 and FIG. 4, the separating part 1312 can be embedded or integrated within the liquid inlet port 1311. The separating part 1312 and the liquid inlet port 1311 form an integral unit, jointly constructing the channel for the aerosol precursor to enter the limiting groove. The separating part 1312 can divide the originally single-channel liquid inlet port 1311 into two or more independent flow channels. The multiple flow channels can be arranged in parallel, distributed in a staggered manner, or exist in other forms within the liquid inlet port 1311, jointly forming the liquid inlet port 1311 that can supply the aerosol precursor in zones.
[0050] The aerosol precursor can flow into the limiting groove through these independent regions, and then contact the atomization core 11 for atomization. With this arrangement, the separating part 1312 divides the liquid inlet port 1311 into multiple regions, which helps to disperse the inflow of the aerosol precursor, avoiding the concentrated liquid supply that a single channel might cause, and making the aerosol precursor more evenly distributed within the limiting groove. This is beneficial for the uniform heating and atomization of the aerosol precursor by the atomization core 11, improving the stability of the atomization effect.
[0051] In some embodiments, the atomization core 11 can also be correspondingly divided into multiple independent heating zones. In that case, the design of the separating part 1312 can achieve multi-channel atomization, i.e., different aerosol precursors flow to their corresponding heating zones through their respective liquid inlet regions, achieving multi-flavor mixing or continuous switching, which increases the functionality of the product. Secondly, by adjusting the size or shape of each separated region, the liquid supply rate for each region can be finely controlled.
[0052] Furthermore, in the region corresponding to the liquid inlet port 1311, the support for the flow-stabilizing member 12 is reduced due to the lack of a support structure. In embodiments of the present disclosure, the separating part 1312 can abut against and support the flow-stabilizing member 12 in the region within the liquid inlet port 1311, which can prevent the flow-stabilizing member 12 from swelling after prolonged immersion, helping to maintain the flow-stabilizing effect of the flow-stabilizing member 12.
[0053] In some embodiments, as shown in FIG. 3 and FIG. 4, the atomization heating assembly 10 also includes a plurality of connecting parts 134. The plurality of connecting parts 134 are formed at the end of the circumferential wall 132 close to the power supply opening and extend outward from the circumferential wall 132 away from the limiting groove, and can be used to fix the atomization heating assembly 10 to a predetermined position.
[0054] As shown in FIG. 3 and FIG. 4, the connecting parts 134 protrude outward from the portion of the circumferential wall 132 away from the limiting groove (i.e., the area where the atomization core 11 is located) . They can be protrusions, tabs, threaded posts, snaps, etc. The connecting parts 134 provide physical contact points or interfaces for connection with external structures. With this arrangement, the plurality of connecting parts 134 can securely mount the atomization heating assembly 10 in a preset position, for example, the preset position of the sealing member 30 to be mentioned later, ensuring that it maintains the correct posture and positional relationship throughout the entire operation cycle, which can guarantee the stability of the atomization process.
[0055] In some embodiments, as shown in FIG. 1, the electrodes 111 of the atomization core 11 can be arranged at both ends of the side away from the liquid inlet end 131. A pair of electrodes 111 is adapted for the power supply terminals 40 to abut against to supply power to the atomization core 11.
[0056] As shown in FIG. 1, the liquid inlet end 131 is the inlet for the aerosol precursor to enter the atomization core 11 for atomization, while the electrodes 111 are provided at both ends of the opposite side. The electrodes 111 can be silver paste electrodes and can be formed by means such as screen printing. The power supply terminal 40 has conductive contacts and can abut against the electrodes 111 to provide electrical energy to the atomization core 11 for heating work.
[0057] In a second aspect of the present disclosure, as shown in FIG. 5 and FIG. 6, an atomization core assembly 100 is provided. The atomization core assembly 100 includes a bracket 20, a sealing member 30, a power supply terminal 40, a base 50, and the atomization heating assembly 10 of any of the above-mentioned types. The bracket 20 has a mounting groove 21. The sealing member 30 is coupled into the mounting groove 21, and the sealing member 30 is provided with an assembly groove 31 and a liquid guiding hole 32 communicating with the assembly groove 31.
[0058] The atomization heating assembly 10 is coupled into the assembly groove 31, and the liquid inlet port 1311 of the fixing member 13 of the atomization heating assembly 10 communicates with the liquid guiding hole 32 of the sealing member 30. The power supply terminal 40 is disposed within the mounting groove 21 and is adapted to supply power to the atomization core 11. The base 50 is coupled to the bracket 20 and the power supply terminal 40 to support the power supply terminal 40 against the atomization core 11.
[0059] As shown in FIG. 5 and FIG. 6, the bracket 20 serves as the basic structure of the atomization core assembly 100, for carrying and fixing other components, forming the overall frame of the atomization core assembly 100. The bracket 20 is provided with a mounting groove 21 for embedding or assembling other parts, which can provide a fixed position for other components. The sealing member 30 is used to prevent leakage of the aerosol precursor and ensure the sealing of the atomization process, and can be made of elastic materials such as rubber, silicone, etc.
[0060] The sealing member 30 is tightly and adaptably installed in the mounting groove 21 of the bracket 20, forming a sealing fit, ensuring that the aerosol precursor will not leak from inside the assembly. The sealing member 30 is also provided with an assembly groove 31, which is a spatial structure for embedding the atomization heating assembly 10. The shape of the assembly groove 31 matches the fixing member 13 of the atomization heating assembly 10, for accommodating and positioning the fixing member 13. One or more liquid guiding holes 32 are provided on the sealing member 30. The liquid guiding holes 32 communicate with the interior of the assembly groove 31 and can form a channel for the aerosol precursor to enter the atomization heating assembly 10 from the precursor chamber. At the same time, the aerosol precursor enters from the liquid guiding hole 32 of the sealing member 30, and through the communicating channel, directly reaches the liquid inlet port 1311 of the fixing member 13, and then enters the limiting groove to contact the atomization core 11 to complete the atomization process.
[0061] As mentioned earlier, the power supply terminal 40 can provide electrical energy to the atomization core 11, causing it to generate heat for the atomization operation. The power supply terminal 40 may include conductive contacts and connecting wires, etc. The power supply terminal 40 is placed in the mounting groove 21 of the bracket 20, and the power supply terminal 40 contacts the electrodes of the atomization core 11 through conductive contacts to form a current path. The base 50 is connected to both the bracket 20 and the power supply terminal 40, jointly constructing the bottom structure of the atomization core assembly 100. The base 50 can provide stable support for the power supply terminal 40, ensuring that it always maintains good electrical contact with the atomization core 11 during use. The base 50 may, through physical support, pressure regulation, etc., help the power supply terminal 40 to overcome the effects of factors such as vibration and thermal expansion, to maintain effective contact and power supply with the atomization core 11.
[0062] In some embodiments, an inner side of the assembly groove 31 is provided with a connecting groove. The connecting groove is adapted for the connecting part 134 to be inserted therein to restrict movement of the connecting part 134. In embodiments of the present disclosure, the connecting groove can receive the connecting part 134 of the atomization heating assembly 10, and can restrict the degrees of freedom of the connecting part 134 after insertion, preventing unnecessary movement or rotation during use.
[0063] The connecting groove can mechanically lock the connecting part 134 through shape fitting, snap-fit structures, etc. With this arrangement, the cooperation between the connecting groove and the connecting part 134 can enhance the connection strength between the atomization heating assembly 10 and the sealing member 30, preventing loosening or detachment caused by vibration, impact, or long-term use, and ensuring the stability of the atomization process. Secondly, by guiding and restricting the connecting part 134 through the connecting groove, it can be ensured that the atomization heating assembly 10 accurately reaches the designed position during assembly, ensuring the smooth flow path of the atomizing liquid and the reliability of the electrode contact.
[0064] In some embodiments, as shown in FIG. 6, the power supply terminal 40 is an elastic contact terminal. The elastic contact terminal is configured to apply a force on the base 50 and the atomization core 11 that causes the base 50 and the atomization core 11 to move away from each other.
[0065] As shown in FIG. 6, the power supply terminal 40 adopts a material or structural design with elasticity, so that it has a certain deformation capability while maintaining electrical contact. An elastic contact terminal usually adopts structures such as springs, elastic metal sheets, or elastic contacts, which can automatically adjust when the contact pressure changes to maintain stable electrical contact. The elastic contact terminal, in its installed and operating state, applies a force to both the base 50 and the atomization core 11. The direction of the force is to cause the base 50 and the atomization core 11 to separate from each other.
[0066] With this arrangement, the force applied by the elastic contact terminal can counteract the thermal expansion effect of the atomization core 11, preventing poor contact or excessive pressure between the atomization core 11 and the base 50 due to thermal expansion and contraction. Secondly, the elastic contact terminal can adjust the applied force according to the actual contact situation between the atomization core 11 and the base 50, ensuring that the contact pressure between the two remains within a suitable range under various operating conditions. This helps to maintain good electrical contact between the atomization core 11 and the power supply terminal 40, which can improve the stability and reliability of the power supply.
[0067] In a third aspect of the present disclosure, an atomization apparatus is provided. The atomization apparatus includes a main body and the atomization core assembly 100 of any of the above-mentioned types, and the atomization core assembly 100 is coupled to the main body.
[0068] When assembling the atomization apparatus, the atomization heating assembly 10 is interfaced with the sealing member 30 as a whole. The atomization core 11 will not experience positional offset during the assembly process and will not affect the sealing effect of the sealing member 30.
[0069] The various embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terminology used herein is intended to best explain the principles of embodiments, their practical application, or technical improvements in the market, or to enable other ordinary skilled persons in the art to understand embodiments disclosed herein.
