Technical Field

[0001] This application relates to the field of atomizer technology, specifically to an atomizing core, an atomizer, an electronic atomizing device, and a method for preparing the atomizing core. Background Technology

[0002] In related technologies, electronic atomizing devices mainly consist of an atomizer and a power supply assembly. The atomizing coil within the atomizer is the core component, primarily comprising a ceramic atomizing coil and a liquid-guiding cotton atomizing coil. Currently, the liquid-guiding cotton atomizing coil in related technologies consists of two parts: inner and outer cotton that wrap around the heating wire to form a cylindrical structure. This design suffers from the following problems:

[0003] 1. The assembly method of the liquid-guiding cotton is complicated, and this assembly method is not suitable for small-sized products. If the same liquid-guiding cotton is used, it will cause wrinkles inside the liquid-guiding cotton. If the heating wire is not strong enough, it may even be crushed.

[0004] 2. The central channel has small-sized liquid-guiding cotton around its circumference, which can easily form a liquid film and cause leakage during suction. Summary of the Invention

[0012] The groove extends from the first end face along the depth direction of the arc-shaped slot.

[0013] The mounting base is provided with an atomizing channel that communicates with the atomizing chamber. The aerosol generating matrix is ​​heated by the heating component to form an aerosol, and then flows out through the atomizing chamber and the atomizing channel in sequence.

[0014] The arc-shaped opening is located on the first end face of the mounting base, compressing and fixing the liquid guide and the heating component within the arc-shaped opening; the atomizing channel is located on the second end face of the mounting base.

[0015] The atomizing channel has a circular cross-section, and the groove has an arc cross-section. The circle and the arc have the same radius and are coaxially arranged.

[0016] The liquid guiding hole is provided on the portion of the first sidewall corresponding to the groove and on the portion of the first sidewall corresponding to the second sidewall.

[0017] The mounting base is further provided with the following between the first sidewall and the second sidewall:

[0018] A seal is provided for sealing the arcuate opening from both sides of the first sidewall and the second sidewall.

[0019] The heating component includes:

[0020] A heating element, corresponding to the groove, is used to heat and atomize the aerosol generating matrix to form an aerosol when energized;

[0021] Two pins are respectively disposed at both ends of the heating element and on both sides of the groove; the two pins are respectively clamped between the portion of the second sidewall located on both sides of the groove and the liquid guiding component, so as to realize the connection between the heating component and the mounting base;

[0022] Two conductive leads are connected to the two pin portions respectively for connection to the power supply assembly, so as to supply power to the heating element through the power supply assembly.

[0023] The liquid guiding component is liquid guiding cotton, and the heating part of the heating component is a metal mesh.

[0025] To address the aforementioned technical problems, the third technical solution provided in this application is: to provide an electronic atomizing device. This electronic atomizing device includes: an atomizer and a power supply assembly; wherein the atomizer is the atomizer described above; and the power supply assembly is connected to the atomizer and is used to supply power to the atomizer.

[0026] To address the aforementioned technical problems, the fourth technical solution provided in this application is: a method for preparing an atomizing core, the method comprising: providing a mounting base; wherein the mounting base includes a first sidewall and a second sidewall disposed opposite to each other, wherein a liquid guiding hole is formed on the first sidewall; an arc-shaped opening is formed between the first sidewall and the second sidewall, and a liquid guiding component and a heating component are stacked and disposed within the arc-shaped opening; wherein the liquid guiding component covers the liquid guiding hole, and the heating component is located on the side surface of the liquid guiding component opposite to the liquid guiding hole.

[0027] The step of stacking the liquid guiding component and the heating component within the arc-shaped opening includes: clamping the liquid guiding component and the heating component with clips to form a preform; placing the preform within the arc-shaped opening; and removing the clips from the arc-shaped opening.

[0028] The step of stacking the liquid guide and the heating component within the arc-shaped opening further includes: adjusting the position of the preform before removing the clamp from the arc-shaped opening, so that the pin portion of the heating component is clamped by the liquid guide and the second sidewall.

[0029] The step of stacking the liquid guide and the heating element within the arc-shaped opening further includes removing excess portions of the liquid guide after removing the clip from the arc-shaped opening.

[0030] The beneficial effects of this application are as follows: Unlike existing technologies, the atomizing core of this application includes a mounting base, a liquid guiding component, and a heating element. The mounting base includes a first sidewall and a second sidewall disposed opposite to each other, with a liquid guiding hole formed on the first sidewall. The liquid guiding component covers the liquid guiding hole and is used to guide the aerosol generating matrix within the liquid guiding hole to the side of the liquid guiding component opposite to the liquid guiding hole. The heating element is disposed on the surface of the liquid guiding component opposite to the liquid guiding hole and is used to heat and atomize the aerosol generating matrix on the liquid guiding component to form an aerosol when energized. The liquid guiding component and the heating element are arranged in an arc shape between the first and second sidewalls. By forming an arc-shaped liquid guiding component within the mounting base, wrinkles in the liquid guiding component are reduced, and damage to the heating element caused by compression is reduced. Simultaneously, the arc-shaped liquid guiding component is larger in size than the circumferentially arranged liquid guiding component, making it less prone to forming a liquid film and solving the problem of liquid leakage during suction. Furthermore, the liquid guiding hole is located on one side wall of the mounting base for unilateral liquid supply, which also avoids the formation of a liquid film, thereby preventing the problem of liquid leakage during suction.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] 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.

[0049] Please see Figure 1 , Figure 1 This is a schematic diagram of the electronic atomizing device provided in this application.

[0050] The electronic atomizing device includes an atomizer 1 and a power supply component 2. The power supply component 2 is connected to the atomizer 1 and supplies power to it. The electronic atomizing device can be used for atomizing liquid substrates. The atomizer 1 stores and atomizes the liquid aerosol generation substrate to form an aerosol that can be inhaled by the user. The liquid aerosol generation substrate can be a medicinal liquid, plant leaf liquid, or other liquid substrates. The atomizer 1 can be used in various fields, such as medical applications and electronic aerosolization. The power supply component 2 includes a battery (not shown), an airflow sensor (not shown), and a controller (not shown). The battery supplies power to the atomizer 1 and controls the heating power and heating time of the atomizing core 12, enabling the atomizer 1 to atomize the substrate to be atomized into an aerosol. The airflow sensor detects changes in airflow within the electronic atomizing device, and the controller activates the electronic atomizing device based on these changes. The atomizer 1 and the power supply component 2 can be integrated or detachably connected, depending on specific requirements.

[0051] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of the atomizer 1 provided in this application.

[0052] The atomizer 1 includes a housing 11 and an atomizing core 12, with the housing 11 having a receiving cavity 13. The atomizing core 12 and the housing 11 can be integrally formed and non-detachably connected, or they can be detachably connected. In this embodiment, the atomizing core 12 and the housing 11 are detachably connected, and the atomizing core 12 is directly connected to the housing 11. This eliminates the need for an additional conduit between the atomizing core 12 and the housing 11, reducing the size of the atomizer and making it more convenient to use. It is understood that the atomizer of this application is a portable atomizer. The atomizing core 12 is disposed within the receiving cavity 13 and cooperates with the housing 11 to form a liquid storage cavity 14. The atomizing core 12 can be used in various fields, such as medical atomization and electronic atomization, to heat and atomize an aerosol-generating matrix from the liquid storage cavity 14 to form an aerosol when powered on.

[0053] Specifically, the outer wall surface of the atomizing core 12 is provided with a protrusion, and the outer wall surface of the housing 11 is provided with a sliding groove, in which a limiting block is provided; the protrusion on the atomizing core 12 is aligned with the sliding groove on the housing 11 and inserted, and the atomizing core 12 or the housing 11 is rotated so that the protrusion is limited by the limiting block in the sliding groove, thereby fixing the atomizing core 12 and the housing 11, and thus achieving a detachable connection between the atomizing core 12 and the housing 11. It can be understood that the outer wall surface of the housing 11 can also be provided with a protrusion, and the outer wall surface of the atomizing core 12 can be provided with a sliding groove, in which a limiting block is provided, to achieve a detachable connection between the atomizing core 12 and the housing 11; a magnetic attraction method can also be used to achieve a detachable connection between the atomizing core 12 and the housing 11; as long as a detachable connection between the atomizing core 12 and the housing 11 is achieved, the specific implementation method is not limited.

[0054] The atomizing core 12 has a suction channel 30 on the side away from the power supply component 2, and the suction channel 30 is connected to the atomizing chamber 22. The side of the suction channel 30 away from the power supply component 2 is open to the atmosphere, so that the aerosol in the atomizing chamber 22 can flow out through the suction channel 30 and be provided to the user for inhalation.

[0055] Please see Figures 3a-7 , Figure 3a This is a schematic diagram of the atomizing core 12 in one embodiment provided in this application. Figure 3b This is a schematic diagram of the structure of the atomizing core 12 in another embodiment provided in this application; Figure 4 yes Figure 3a A structural schematic diagram of the provided mounting base 15 from a first-view perspective; Figure 5 yes Figure 3a A schematic diagram of the provided mounting base 15 from a second-view perspective; Figure 6 yes Figure 3a A schematic diagram of the provided mounting base 15 from a third-person perspective; Figure 7 yes Figure 3a A cross-sectional view of the atomizing core 12 along the AA direction.

[0056] The atomizing core 12 includes a mounting base 15, a liquid guiding component 16, and a heating element 17. The mounting base 15 has an arc-shaped opening 18 and an atomizing channel 19. The mounting base 15 includes a first sidewall 181 and a second sidewall 182 disposed opposite to each other, wherein at least the inner surface of the first sidewall 181 is arc-shaped. In one embodiment, the inner surfaces of both the first sidewall 181 and the second sidewall 182 are arc-shaped. The first sidewall 181 has a liquid guiding hole 20, and the second sidewall 182 has a groove 21; the groove 21 communicates with the atomizing channel 19.

[0057] The liquid guiding hole 20 is a through hole penetrating the first sidewall 181. The shape of the liquid guiding hole 20 is not limited and can be circular, elliptical, rectangular, triangular, etc. The shape and size of the liquid guiding holes 20 can be the same or different. The liquid guiding holes 20 can be distributed on the entire first sidewall 181 or a part of the first sidewall 181. The cross-section of the groove 21 can be arc-shaped, rectangular, triangular, etc. The extension direction, width, and length of the groove 21 are not limited.

[0058] In one embodiment, the arc-shaped opening 18 is arc-shaped, and the cross-section of the groove 21 is also arc-shaped. Since the groove 21 is located on the inner surface of the second sidewall 182, the radius of curvature of the groove 21 is necessarily smaller than the radius of curvature of the arc-shaped opening 18. The arc-shaped opening design of the mounting base 15 in this application can reduce the difference in arc length between the inner and outer sides of the liquid guide 16, thereby reducing wrinkles in the liquid guide 16 and reducing the risk of damage to the heating component due to compression.

[0059] A liquid guide 16 is disposed within the arc-shaped opening 18, covering the liquid guide hole 20, and cooperates with the groove 21 to form an atomizing chamber 22. The liquid guide 16 can cover all or part of the liquid guide hole 20. The liquid guide 16 can cover the entire groove 21, or it can only cover a part of the groove 21. For example, the width of the liquid guide 16 can be less than the length of the groove 21. By setting the liquid guide 16 only within the arc-shaped opening 18 of the mounting base to form an arc-shaped liquid guide and not within the groove 21, wrinkles in the liquid guide 16 can be reduced. At the same time, the arc-shaped liquid guide 16 is larger in size than the annular liquid guide in the existing heating base, making it less likely to form a liquid film, thus solving the problem of liquid leakage during suction in related technologies. In one embodiment, the shape of the liquid guide 16 is also arc-shaped.

[0060] The liquid guiding element 16 is used to guide the aerosol generating matrix in the liquid guiding hole 20 to the side surface of the liquid guiding element 16 opposite to the liquid guiding hole 20. In this application, the liquid guiding hole 20 is only provided on the first side wall 181 of the mounting base for unilateral liquid supply, which can also avoid the formation of a liquid film and thus avoid the problem of liquid leakage by suction.

[0061] The heating element 17 is disposed on the side surface of the liquid guide 16 opposite to the liquid guide hole 20, that is, the heating element 17 is disposed on the inner arc surface of the arc-shaped liquid guide 16, and is used to heat and atomize the aerosol generation matrix on the liquid guide 16 to form an aerosol when energized.

[0062] The arc-shaped design allows the heating element 17 to remain in close contact with the liquid guide 16 during thermal stress, preventing dry burning and reducing wear on the heating wire. Please refer to [link / reference]. Figure 10 , Figure 10This is a simulation verification diagram of the thermal strain process of the heating network provided in this application. It can be seen that the thermal strain direction of the heating component 17 is towards the Z direction (the thickness direction of the liquid guide 16). Therefore, setting the liquid guide 16 to an arc shape can keep the heating component 17 and the liquid guide 16 in contact at all times. After cooling, the heating component 17 returns to its original state. The liquid guide 16 can store and guide the aerosol-generated matrix in the liquid storage cavity 14. The shape of the liquid guide 16 can be, but is not limited to, a sheet-like body; in this embodiment, the liquid guide 16 is a sheet-like body.

[0063] The liquid guiding element 16 is arc-shaped, and the angle corresponding to the arc is from 0 degrees to 180 degrees. In extreme cases, as long as the liquid guiding element 16 is arc-shaped, it can produce fewer wrinkles and avoid the formation of a liquid film. However, to achieve both the above function and normal liquid guiding function, the liquid guiding element 16 needs to reach a certain angle and arc length. In one embodiment of this application, the angle of the liquid guiding element 16 is set to 20 degrees to 55 degrees. Preferably, the angle of the liquid guiding element 16 is set to 30 degrees to 45 degrees. More preferably, the angle of the liquid guiding element 16 is set to 35 degrees to 40 degrees. In other embodiments, the angle of the liquid guiding element 16 can also be set to other angles and arc lengths, and this application does not limit this.

[0064] In one embodiment, the mounting base 15 has a first end face 25 and a second end face 26 facing each other; an arc-shaped opening 18 is disposed on the first end face 25 of the mounting base 15, compressing and fixing the liquid guide 16 and the heating assembly 17 within the arc-shaped opening 18; an atomizing channel 19 is disposed on the second end face 26 of the mounting base 15. The arc-shaped opening 18 is an arc-shaped groove disposed on the first end face 25 of the mounting base 15, and the arc-shaped groove can be a through groove or a blind groove. A through groove means that both ends of the arc-shaped groove are open, and a blind groove means that both ends of the arc-shaped groove are closed. The arc-shaped groove can also have one open end and the other closed end. In one embodiment of this application, setting the arc-shaped opening 18 as a groove can facilitate the assembly of the liquid guide 16 by inserting the liquid guide 16 into the groove from the opening of the groove, that is, by inserting the liquid guide 16 into the groove from one side of the first end face 25 of the mounting base 15. Furthermore, the slot is a through-slot structure, which greatly facilitates the alignment of the heating element 17 on the liquid guide 16 with the groove 21. For example, the liquid guide 16 can be pulled along both ends of the slot to align the heating element 17 with the groove 21. The width of the liquid guide 16 can be greater than, less than, or equal to the depth of the arc-shaped slot. In one embodiment, the width of the liquid guide 16 is equal to the depth of the arc-shaped slot, one side of the liquid guide 16 abuts against the bottom surface of the arc-shaped slot, and the other side is flush with the first end face 25 of the mounting base 15.

[0065] The liquid-guiding component 16 can be a loose, porous material such as liquid-guiding cotton, a fiber layer, or porous ceramic. Specifically, the liquid-guiding cotton can be a single-layer or multi-layer structure formed from non-woven fabric and / or flax. In the prior art, the liquid-guiding cotton is placed in a hollow cylinder within the annular sidewall of the heating element, typically with a radius of curvature less than 6 mm. In one embodiment, the radius of curvature of the arc-shaped opening 18 and the liquid-guiding component 16 can be 6 mm to 14 mm. A larger radius of curvature can further reduce wrinkles in the liquid-guiding component 16. In one embodiment, the liquid-guiding component 16 is a six-layer liquid-guiding cotton structure. With a radius of curvature of 6 mm to 14 mm, the compression amount, i.e., the compression thickness, of the liquid-guiding component 16 is 1.3 mm to 1.8 mm. It can be understood that the smaller the compression amount, the smaller the deformation of the liquid-guiding cotton, and the fewer wrinkles are generated.

[0066] Please see Figure 11 , Figure 11 This is a schematic diagram illustrating the principle of reducing wrinkles in fluid guiding components with a large radius of curvature, as provided in this application. Figure 11 The large circle 23 and the small circle 24 have the same thickness, representing the state when using the same thickness of liquid-guiding cotton with different radii of curvature. The ratio of their inner and outer arc lengths, L, is also relevant. 内 / L 外 =71.4%>L 内’ / L 外’ =39.4%, of which L 内 and L 外 It is the ratio of the inner and outer arc lengths of the great circle 23, L 内’ and L 外’ It is the ratio of the inner and outer arc lengths of the small circle 24. It can be assumed that the smaller the difference between the inner and outer arc lengths, the fewer wrinkles will be produced when using the same thickness of liquid-guiding cotton. Therefore, a large radius of curvature can reduce wrinkles in the liquid-guiding component 16.

[0067] In another embodiment of the atomizing core 12 provided in this application, please refer to the structure. Figure 3b and Figure 8 , Figure 8 This is a structural schematic diagram of the seal 27 provided in this application. A seal 27 is also provided between the first side wall 181 and the second side wall 182 of the mounting base 15 for sealing the arc-shaped opening 18 from both sides of the first side wall 181 and the second side wall 182.

[0068] Specifically, the sealing element 27 is disposed on both sides of the liquid guiding element 16 and extends along the depth of the arc-shaped opening 18 to seal the arc-shaped opening 18 from the first side wall 181 to the second side wall 182, preventing the atomized matrix or atomized gas on the liquid guiding element 16 from leaking from both sides of the arc-shaped opening 18.

[0069] Please see Figure 8The outer wall of the seal 27 is provided with a recess 271 and a flange 272. The side wall of the arc-shaped groove is provided with a protrusion and a groove (not shown) that match and connect with the recess 271 and the flange 272. The recess 271 and the protrusion in the side wall of the arc-shaped groove are matched and connected, and the flange 272 and the groove in the side wall of the arc-shaped groove are matched and connected. The seal 27 is fixed to the mounting base 15 by the recess 271 and the flange 272. Specifically, in one embodiment, the recess 271 and the flange 272 are provided on the seal 27. During installation, the side of the seal 27 with the recess 271 is aligned with the protrusion on the side wall of the arc-shaped groove, and the side of the seal 27 with the flange 272 is aligned with the groove on the side wall of the arc-shaped groove for matching and engaging, thereby completing the fixing of the seal 27 and the mounting base 15. It is understood that, in another embodiment, the recess 271 and flange 272 are disposed on the side wall of the arc-shaped groove, and the protrusion and groove are disposed on the seal 27, which can also achieve the matching connection between the two. The recess 271 and flange 272 can also prevent the seal 27 from shaking in the depth direction of the arc-shaped groove, making the installation of the two more stable and improving the installation stability of the seal 27 and the arc-shaped groove. In addition, the seal 27 and the liquid guide 16 can be in contact or not, without affecting the sealing function of the seal 27. In one embodiment, if the seal 27 and the liquid guide 16 are made to contact each other, an installation groove 273 can be opened on the side wall of the seal 27 near the liquid guide 16, so that the liquid guide 16 can be engaged in the installation groove 273, improving the connection stability between the seal 27 and the liquid guide 16. Before installing the seal 27, the liquid guide 16 can be pre-cut to match the mounting groove 273 on the side wall of the liquid guide 16, and then snapped into it from the first end face 25. Then, the seals 27 on both sides of the liquid guide 16 can be installed, improving the ease of installation. The shape, size, and number of the recess 271 and the flange 272 can be adjusted as needed, as long as a matching connection between the two can be achieved; this application does not impose any limitations on this.

[0070] The shape and position of the atomizing channel 19 are not limited, as long as it communicates with the groove 21. In one embodiment, the groove 21 extends from the first end face 25 along the depth direction of the arc-shaped slot. The atomizing channel 19 is disposed on the second end face 26 of the mounting base 15 opposite to the first end face 25, and is directly connected to the end of the groove 21 away from the first end face 25. In one embodiment of this application, the groove 21 extends along the depth direction of the arc-shaped slot, and its length is equal to the depth of the arc-shaped slot. The groove 21 and the atomizing channel 19 form a through hole from the first end face 25 to the second end face 26. The groove 21 is covered by the liquid guiding member 16 and forms an atomizing cavity 22 with the liquid guiding member 16. The end of the atomizing cavity 22 away from the first end face 25 communicates with the atomizing channel 19. In one embodiment of this application, the bottom of the arc-shaped slot is also connected to the atomizing channel 19, that is, the arc-shaped slot, the groove 21, and the atomizing channel 19 together form a through hole from the first end face 25 to the second end face 26. The part of the bottom wall of the arc-shaped slot covered by the liquid guide 16 can also be closed. Only the part where the groove 21 and the liquid guide 16 form the atomizing chamber 22 is a through groove, which can also be set to realize the function of the atomizing chamber 22.

[0071] In this embodiment, the atomizing chamber 22 is formed by a semi-circular arc and the arc-shaped inner sidewall of the liquid guiding component 16. The radius of curvature of the arc-shaped inner sidewall of the liquid guiding component 16 is larger than the radius of curvature of the semi-circular arc. The heating element 17 is a sheet-like body. The heating element 17 is electrically connected to both the battery and the controller of the power supply component 2, so that the battery can provide power to the heating element 17, and the controller can control the heating duration, heating power, etc. of the heating element 17.

[0072] In one embodiment, see Figure 6-7 The atomizing channel 19 is connected to the groove 21 and the arc-shaped slot. The cross-section of the atomizing channel 19 is circular, and the cross-section of the groove 21 is an arc. The circular and arc have the same radius and are coaxially arranged. It can be understood that when the user inhales the electronic atomizing device, the aerosol generating matrix can enter the liquid guiding component 16 through the liquid guiding hole 20. Then, it can be heated and atomized by the heating component 17 located on the side of the liquid guiding component 16 opposite to the liquid guiding hole 20. After that, it can enter the atomizing chamber 22, and finally, the atomized particles can be guided into the user's mouth for inhalation through the atomizing channel 19.

[0073] In other words, in this application, the atomizing channel 19, the groove 21, and the arc-shaped slot together form the central channel of the mounting base 15. The sidewall of the central channel comprises two parts, wherein the radius of curvature of the first part of the sidewall is greater than the radius of curvature of the second part of the sidewall. The first part of the sidewall is a portion of the first sidewall 181, and the second part of the sidewall is the sidewall of the groove 21. Furthermore, two notches 29 are formed on the sidewall of the central channel along the extending direction of the first part of the sidewall, that is, the two ends of the arc-shaped slot. The middle part of the liquid guiding member 16 is disposed in the central channel, and the two ends are respectively disposed in the two notches 29.

[0074] Please see Figure 5 In one embodiment of this application, a cylindrical protrusion is provided on the second end face 26 of the mounting base 15, and a through hole is formed in the cylindrical protrusion to create an atomizing channel 19, which can be easily detachably connected to the suction channel 30 of the housing 11. In other embodiments, the port of the atomizing channel 19 can also be configured to be flush with or recessed into the second end face 26. During connection, the suction channel 30 of the housing 11 is inserted into the atomizing channel 19, as long as a connection with the housing 11 can be achieved, this application does not impose any restrictions on this. It is understood that the specific arrangement of the atomizing channel 19 and the groove 21 can also be designed into other shapes as needed, and this application does not impose any restrictions on this.

[0075] Similarly, Figure 4 As shown, liquid guiding holes 20 are provided on the portion of the first sidewall 181 corresponding to the groove 21, and on the portion of the first sidewall 181 corresponding to the second sidewall 182. The first sidewall 181 includes a middle portion 1810 corresponding to the groove 21 and two side portions 1812 corresponding to the two sides of the groove 21. Liquid guiding holes 20 are provided on both the middle portion 1810 and the two side portions 1812 of the first sidewall 181. Generally, the liquid guiding holes 20 are located in the middle portion 1810 of the first sidewall 181 to achieve stable liquid supply and heating atomization. In this application, they are located on the entire sidewall surface of the first sidewall 181, which not only achieves the above functions normally, but also effectively increases the liquid supply of the liquid guiding holes 20 to the liquid guiding component 16. In addition, this application does not limit the structure, shape, or number of liquid guiding holes 20, as long as they can achieve the normal liquid guiding function. It is understood that providing at least one hole can also achieve the liquid guiding function. However, it should be noted that at each location where the liquid guide hole 20 is set, a liquid guide component 16 must be installed to draw in the liquid; otherwise, leakage may easily occur.

[0076] Please see Figure 9 , Figure 9 This is a schematic diagram of the heating component provided in this application. The heating component 17 includes a heating element 171, two pins 172, and two conductive leads 173. Specifically, the heating element 171 is disposed corresponding to the groove 21 and is used to heat and atomize the aerosol to generate a matrix to form an aerosol when energized. In one embodiment, the heating element 171 and the two pins 172 can be integrally formed. The heating element 171 is disposed corresponding to the groove 21, and the two pins 172 are respectively disposed on both sides of the groove 21 and held by the two ends of the liquid guiding member 16 and the second sidewall 182.

[0077] Two pin portions 172 are respectively disposed at both ends of the heating portion 171 and on both sides of the groove 21; the two pin portions 172 are respectively clamped between the portions of the second side wall 182 located on both sides of the groove 21 and the liquid guide 16, so as to realize the connection between the heating component 17 and the mounting base 15.

[0078] Two conductive leads 173 are connected to two pin portions 172 respectively for connection to the power supply assembly 2, so as to supply power to the heating element 171 through the power supply assembly 2. The power supply assembly 2 is powered by a battery, so that the atomizer 1 does not need to be connected to a 220V AC power supply, making it more flexible to use and convenient for carrying around.

[0079] Two pin portions 172 are spaced apart for electrical connection with external leads (not shown) so that the heating component 17 is electrically connected to the power supply component 2 via the external leads.

[0080] The heating element 171 is a metal mesh, which has good thermal conductivity. The two lead parts 172 are cotton-pressed steel sheets, which serve two purposes: firstly, to supply power to the two conductive leads 173; secondly, by fixing the two ends of the metal mesh of the heating element 171, it can be firmly fixed between the mounting base 15 and the liquid guiding component 16.

[0081] The heating element 171 is used to conduct current and generate heat when energized, thereby heating the aerosol matrix in the liquid-conducting component 16. The opposite ends of the heating element 171 are respectively connected to two pin portions 172, so that a current loop is formed in the heating element 171 when a voltage is applied between the two pin portions 172. In this embodiment, the two pin portions 172 are respectively provided at opposite ends along the length of the heating element 171, and each forms a connection point with one of the two ends of the heating element 171.

[0082] Specifically, such as Figure 8 As shown, the heating element 171 includes a plurality of heating units 174. The plurality of heating units 174 may be connected sequentially, that is, the plurality of heating units 174 may be connected in series. In other embodiments, the plurality of heating units 174 may also be connected in parallel, or may be a combination of series and parallel connection.

[0083] The heating elements 174 can be closed rings, notched rings, or other shapes. In this embodiment, the heating elements 174 are closed rings. The closed ring shape allows for a larger contact area between the heating elements 174 and the liquid guide 16, enabling the heating elements 174 to contact more aerosols for matrix heating, resulting in higher heating efficiency for the heating assembly 17. The shapes of the heating elements 174 can be identical, partially identical, or completely different. In the first embodiment of this application, the shapes of the heating elements 174 are identical.

[0084] The atomizing core provided in this embodiment utilizes a mounting base with a liquid-guiding hole on the first side wall of the mounting base for unilateral liquid supply, preventing the formation of a liquid film and thus avoiding leakage issues. Simultaneously, a liquid-guiding component is placed within the arc-shaped opening of the mounting base, covering the liquid-guiding hole and engaging with a groove in the mounting base to form an atomization chamber. This allows the aerosol-generating matrix within the liquid-guiding hole to be guided to the side of the liquid-guiding component facing away from the hole. The arc-shaped liquid-guiding component, positioned within the arc-shaped opening of the mounting base, reduces wrinkles and minimizes damage to the heating element from compression. Furthermore, the arc-shaped component, being larger and not circular than a circumferentially shaped component, is less prone to forming a liquid film, thus resolving the leakage problem. Additionally, a heating element is placed on the side of the liquid-guiding component facing away from the liquid-guiding hole, heating and atomizing the aerosol-generating matrix on the component when energized to form an aerosol.

[0085] Specifically, the atomizing core involved in the above embodiments can be prepared by the following method.

[0086] Please see Figure 12 , Figure 12 This is a schematic flowchart illustrating the preparation method of the atomizer core provided in this application. In this embodiment, a method for preparing an atomizer core is also provided, the method comprising:

[0087] S1: Mounting bracket provided.

[0088] The mounting base 15 includes a first sidewall 181 and a second sidewall 182 disposed opposite to each other. A liquid guiding hole 20 is provided on the first sidewall 181, and an arc-shaped opening is formed between the first sidewall and the second sidewall.

[0089] S2: The liquid guiding component 16 and the heating component 17 are stacked in the arc-shaped opening.

[0090] The liquid guiding component 16 covers the liquid guiding hole 20, and the heating component 17 is located on the side surface of the liquid guiding component 16 opposite to the liquid guiding hole 20.

[0091] In one specific embodiment, please refer to Figure 13 , Figure 13 yes Figure 12 The sub-flowchart for step S2. Step S2 specifically includes:

[0092] S21: Clamping the liquid guiding component and the heating component with clips to form a preform.

[0093] The clamping piece is a rigid thin sheet capable of elastic deformation. Preferably, the clamping piece is a metal sheet. Most preferably, the clamping piece is a steel sheet. In other embodiments, other methods can be used to install the liquid guiding component 16 and the heating component 17, and the clamping piece can also be made of other materials or in other forms, as long as it can clamp the liquid guiding component 16 and the heating component 17 and be placed together into the arc-shaped opening 18 of the mounting base 15. This application does not impose any restrictions on this.

[0094] S22: Place the preform inside the arc-shaped opening.

[0095] Specifically, since the liquid guiding component 16 has a certain thickness, if it and the heating component 17 are each placed separately into the arc-shaped opening 18, the liquid guiding component 16 first needs to be compressed to a certain thickness before it can be placed in. After the liquid guiding component 16 is placed into the arc-shaped opening 18, placing the heating component 17 will inevitably be more difficult. On the one hand, the liquid guiding component 16 needs to be compressed to ensure that the heating component 17 is placed accurately, and on the other hand, the pins 172 at both ends of the heating component 17 must be placed exactly between the notch 29 of the second sidewall 182 and the liquid guiding component 16, which brings considerable difficulties to the installation. In one embodiment of this application, the liquid guiding component 16 and the heating component 17 are first stacked, and then two clips are used to clamp the liquid guiding component 16 and the heating component 17 to form a preform. The preform is then placed into the arc-shaped opening 18 together, which allows for very convenient assembly, simple operation, and high accuracy.

[0096] In one specific embodiment, after step S22, the method may further include: adjusting the position of the preform so that the pin portion 172 of the heating component 17 is clamped by the liquid guide 16 and the second sidewall 182.

[0097] Specifically, by clamping the liquid guide 16 and the heating element 17 with the two clips in the above steps, the liquid guide 16 can be easily compressed. The clips are also long at both ends, which makes it easy to adjust the position of the liquid guide 16 and the heating element 17. This ensures that the heating part 171 of the heating element 17 is positioned in accordance with the position of the groove 21. At the same time, it ensures that the pins 172 at both ends of the heating element 17 are positioned between the notch 29 of the second side wall 182 and the liquid guide 16. This allows the heating part 171 of the heating element 17 to heat the aerosol on the liquid guide 16 and atomize it to form an aerosol.

[0098] S23: Remove the clip from the arc-shaped opening.

[0099] Specifically, after adjusting the positions of the liquid guide 16 and the heating element 17, gently remove the clips one by one from the arc-shaped opening 18, while ensuring that the positions of the liquid guide 16 and the heating element 17 are not affected.

[0100] Furthermore, in one specific embodiment, step S23 may further include: removing excess portions of the fluid guide 16. That is, after removing the clip from the arc-shaped opening 18, excess portions of the fluid guide 16 are cut or trimmed around the outer wall of the mounting base 15 to match the size of the arc-shaped opening 18.

[0101] The atomizer core preparation method provided in this embodiment simplifies the assembly process without changing the liquid guiding component and heating wire material, and improves the assembly consistency and accuracy of the liquid guiding component, greatly facilitating the installation operation of the atomizer core.

[0102] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
