Description

Technical Field

[0001] This application belongs to the field of atomization technology, and more specifically, relates to an atomizing core and atomizing device. Background Technology

[0002] Atomizing devices heat an aerosol-forming matrix to generate aerosols. The atomizing core is a key component of the atomizing device, comprising a heating element and a liquid guide. The liquid guide is used to transport the aerosol-forming matrix, while the heating element generates heat when energized, thereby heating the aerosol-forming matrix located within the liquid guide.

[0003] In related technologies, the heating element is a single-layer structure, which makes the area corresponding to the liquid guide and the heating element easily damaged by high temperature, leading to the problem of burnt core and affecting the taste of the atomized product. At the same time, the carbonized products caused by the high temperature damage to the liquid guide may adhere to the surface of the heating element, resulting in a reduction in the heating efficiency of the heating element and ultimately affecting the user experience of the atomizing core.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0045] In a first aspect, embodiments of this application provide an atomizing core 100, which includes a heating element 10 and a first liquid guiding element 20. The heating element 10 includes a heating part 1 and a pin 2, the structure of which is shown in the figure.

[0046] In this embodiment, the heating element 1 and the pin 2 in the heating element 10 can be an integrally formed structure, or they can be fixedly connected by welding.

[0047] Specifically, the heating element 1 includes at least a first heating element 11, a first connecting member 12, and a second heating element 13 arranged sequentially along its length, wherein the first heating element 11 and the second heating element 13 are arranged opposite to each other and spaced apart. A first liquid guiding member 20 is located between the first heating element 11 and the second heating element 13, and is used to adsorb and transport aerosol to form a matrix. The first liquid guiding member 20 is located between the first heating element 11 and the second heating element 13. Figure 1 It is not shown in the drawing.

[0048] Please see Figure 1 At this point, the heating element 1 has a double-layer sheet structure, and the first heating element 11 and the second heating element 13 are mesh heating sheets arranged opposite each other. The heating element 1 is folded along its length so that the two ends of the heating element 1 are arranged opposite each other in the length direction. At this time, the first heating element 11 and the second heating element 13 are arranged opposite each other, and the overall integrity of the heating element 1 is good. The first liquid guiding element 20 located between the oppositely arranged first heating element 11 and the second heating element 13 can further improve the structural strength and structural stability of the heating element 1.

[0049] The first liquid guiding element 20 adsorbs a suitable amount of aerosol forming matrix to achieve the transport or delivery of the aerosol forming matrix within the first liquid guiding element 20. By filling the first liquid guiding element 20 between the first heating element 11 and the second heating element 13 of the heating element 10, the first heating element 11 and the second heating element 13 can respectively heat the aerosol forming matrix adsorbed at different positions within the first liquid guiding element 20.

[0050] "Matching" means that the surface of the first liquid guiding element 20 is in contact with or against the opposing surface of either the first heating element 11 or the second heating element 13.

[0051] For example, the surface of the first liquid guiding member 20 located between the first heating element 11 and the second heating element 13 can be in just contact with the surfaces of the two elements; or, the surface of the first liquid guiding member 20 can be arranged to press against the surfaces of the first heating element 11 and the second heating element 13.

[0052] Specifically, the first liquid guiding element 20 is made of porous material and may have a capillary structure or other existing structures in related technologies, mainly used to realize the transportation of aerosol matrix.

[0053] For example, the first liquid guiding component 20 can be made of any one or more of the following materials: organic cotton, glass fiber, and ceramic fiber, to ensure that the first liquid guiding component 20 has good aerosol forming matrix adsorption and transport performance, and can continuously adsorb the aerosol forming matrix and continuously transport it to the heating element 10, so as to ensure a continuous and stable supply of the aerosol forming matrix to the heating element 10.

[0054] Depending on the material, the transport of the aerosol matrix within part of the first liquid guiding component 20 can be directional or non-directional.

[0055] In some feasible implementations, the resistance values ​​of the first heating element 11 and the second heating element 13 can be set to be different. For example, the resistance value of the first heating element 11 can be set to be greater than the resistance value of the second heating element 13, or the resistance value of the first heating element 11 can be set to be less than the resistance value of the second heating element 13.

[0056] It is understandable that by adjusting the structure of the heating element 1 to have a first heating element 11 and a second heating element 13 arranged at relative intervals with different resistance values, the first heating element 11 and the second heating element 13 can act on different positions of the material that has adsorbed a certain amount of aerosol forming matrix in an interval arrangement. At this time, the aerosol forming matrix can not only improve its fluidity under the heating action of the heating element 1, but also use the two heating elements with different resistance values ​​to guide the aerosol forming matrix after being heated by the heating element with low heating power to flow towards the side of the heating element with high heating power. This can not only improve the atomization effect, but also help reduce carbon buildup and core clogging problems of the heating element 10, and ultimately improve the performance and service life of the heating element 10.

[0057] In this embodiment, the resistance value of the first heating element 11 is set to be less than the resistance value of the second heating element 13.

[0058] When the heating element 10 is energized and heats up, the aerosol forming matrix can accelerate its flow rate under the action of heat. Since the resistance value of the second heating element 13 is greater than that of the first heating element 11, the second heating element 13 can be used to preheat the aerosol forming matrix located in the first liquid guiding element 20 to increase the flow rate of the aerosol forming matrix. The first heating element 11 can be used to heat the aerosol forming matrix located in the first liquid guiding element 20 to atomize and generate aerosol.

[0059] When energized, the second heating element 13, with higher resistance, can be used to preheat the aerosol forming matrix, while the first heating element 11, with lower resistance, is used to heat the aerosol forming matrix. After preheating, the aerosol forming matrix adsorbed in the first liquid guiding element 20 moves at a faster rate and towards the first heating element 11, eventually achieving atomization under the heating action of the first heating element 11.

[0060] Under the preheating effect of the second heating element 13, not only can the aerosol forming matrix move from the side closer to the second heating element 13 to the side closer to the first heating element 11, but also more aerosol forming matrix can move into the first liquid guiding element 20.

[0061] Considering the limited storage capacity of the aerosol-forming matrix in the first liquid guiding component 20, the storage capacity depends on the adsorption rate of the aerosol-forming matrix by the first liquid guiding component 20 and the release rate of aerosol at the first heating element 11 in the heating element 10. When the two can reach a dynamic equilibrium, the first liquid guiding component 20 can work continuously and stably without scorching. When the aerosol release rate is greater than the adsorption rate, the first liquid guiding component 20 is prone to dry burning due to insufficient supply of aerosol-forming matrix, which in turn leads to scorching. In this embodiment, by setting the heating element 10 to include a second heating element 13 with a preheating function and a first heating element 11 with a heating function, while the first heating element 11 forms an aerosol, the second heating element 13 can be used to preheat a portion of the aerosol forming matrix in the first liquid guiding element 20, thereby accelerating the movement rate of the aerosol forming matrix in the first liquid guiding element 20 and improving the adsorption rate of the aerosol forming matrix by the first liquid guiding element 20 to a certain extent. Therefore, it can alleviate the problem of insufficient liquid supply in the first liquid guiding element 20, thereby reducing the possibility of dry burning in the contact area between the first liquid guiding element 20 and the first heating element 11, helping to reduce the risk of core clogging in the first liquid guiding element 20, and ultimately extending the service life of the atomizing core 100.

[0062] In some embodiments, the resistance value of the first heating element 11 can be 0.2Ω to 1.5Ω. Within this range, it can be adaptively adjusted according to design needs. For example, the resistance value of the first heating element can be set to any value such as 0.2Ω, 0.3Ω, 0.4Ω, 0.5Ω, 0.6Ω, 0.7Ω, 0.8Ω, 0.9Ω, 1.0Ω, 1.1Ω, 1.2Ω, 1.3Ω, 1.4Ω, or 1.5Ω.

[0063] The resistance value of the second heating element 13 can also be set to 1.0Ω to 2.0Ω. Within this range, it can be adjusted adaptively according to design needs. For example, the resistance value of the second heating element can be set to any value such as 1.0Ω, 1.1Ω, 1.2Ω, 1.3Ω, 1.4Ω, 1.5Ω, 1.6Ω, 1.7Ω, 1.8Ω, 1.9Ω, 2.0Ω, etc.

[0064] It is important to note that the resistance of the first heating element 11 must always be less than the resistance of the second heating element 13. For example, when the resistance of the second heating element 13 is 1.0Ω, the resistance of the first heating element 11 must be less than 1.0Ω.

[0065] Specifically, the preferred resistance range of the first heating element 11 is set to 0.2Ω to 0.8Ω, and the preferred resistance range of the second heating element 13 is set to 1.5Ω to 2.0Ω.

[0066] For a better description of the structure of the heating element 10, please refer to [link / reference]. Figure 1 The end of the first heating element 11 closest to the first connector 12 is defined as the first end 111, and the end facing away from the first connector 12 is defined as the second end 112; the end of the second heating element 13 closest to the first connector 12 is defined as the third end 131, and the end facing away from the first connector 12 is defined as the fourth end 132. That is, the first heating element 11 is connected to the first connector 12 through the first end 111, and the second heating element 13 is connected to the end of the first connector 12 facing away from the first heating element 11 through the third end 131.

[0067] The heating element 10 also includes a second connector 14, one of which is located at the end of the first heating element 11 facing away from the first connector 12; and / or, one of the second connectors 14 is located at the end of the second heating element 13 facing away from the first connector 12. Please refer to [link / reference]. Figure 1 The second end 112 of the first heating element 11 is connected to a second connector 14, and the fourth end 132 of the second heating element 13 is connected to a second connector 14.

[0068] In some embodiments, the projected area of ​​the first heating element 11 in the thickness direction is set to be smaller than the projected area of ​​the second heating element 13 in the thickness direction.

[0069] Specifically, assuming that the first heating element 11 and the second heating element 13 have the same thickness and height, and are processed using the same materials, please refer to... Figure 1Along the direction indicated by the arrow in the figure (i.e., the length direction of the heating element 1), the distance between the first end 111 and the second end 112 is less than the distance between the third end 131 and the fourth end 132. At this time, the orthogonal projection area of ​​the first heating element 11 in the thickness direction is less than the orthogonal projection area of ​​the second heating element 13 in the thickness direction, and the resistance value of the first heating element 11 is less than the resistance value of the second heating element 13.

[0070] Please see Figure 1 The heating element 1 is formed by bending a plate-shaped material of a certain thickness, and the first heating element 11, the first connecting element 12, the second heating element 13 and the second connecting element 14 are integrally formed.

[0071] Specifically, the first heating element 11 is provided with a plurality of first mesh holes 113, at least some of which are arranged sequentially along the extending direction of the heating part 1. Similarly, the second heating element 13 is provided with a plurality of second mesh holes 133, at least some of which are arranged sequentially along the extending direction of the heating part 1.

[0072] Because the resistances of the first heating element 11 and the second heating element 13 are different, the line width of the mesh formed between two adjacent first mesh openings 113 is different from the line width of the part of the mesh formed between two adjacent second mesh openings 133.

[0073] In other similar embodiments, the first heating element 11 and the second heating element 13 may be configured to have different thicknesses. The first heating element 11 and the second heating element 13 with different thicknesses can be processed and prepared separately and then spliced ​​together by welding or other methods.

[0074] For example, the heating element 1 is configured as a welded structure, and the first heating element 11 and the second heating element 13 are made of different metal materials. The two different metal materials can be fixedly connected by welding or high-temperature pressing, etc. The above connection methods have been disclosed in related technologies and will not be described in detail here.

[0075] Of course, in other similar embodiments, the heating element 1 may also include a third heating element that is spaced apart from the second heating element 13 by another first connector 12. The resistance value of the third heating element may be different from the resistance values ​​of the first heating element 11 and the second heating element 13, so as to give the heating element 10 a more flexible resistance adjustment range, which will not be elaborated here.

[0076] In some embodiments, pin 2 includes a first pin 21 and a second pin 22, wherein the first pin 21 is connected to the second connector 14 and the second pin 22 is connected to the first connector 12.

[0077] Please see Figure 1There are two first pins 21. The two first pins 21 can be connected to the first heating element 11 and the second heating element 13 respectively through the second connector 14, and are located at both ends of the heating part 1 in the length direction. Since the first heating element 11 and the second heating element 13 are arranged opposite to each other, the two first pins 21 connected to both ends of the heating part 1 are also exactly opposite to each other.

[0078] Please see Figure 1 Along the length of the heating element 1, the second pin 22 is connected to the middle of the heating element 1 via the first connector 12 located between the first heating element 11 and the second heating element 13; the two first pins 21 are connected to the two ends of the heating element 1 via the end of the first heating element 11 away from the second heating element 13 and the end of the second heating element 13 away from the first heating element 11.

[0079] With the first heating element 11 as a reference, the first pin 21 and the second pin 22 are located at the two ends of the first heating element 11, respectively. The second pin 22 can be used to cooperate with different first pins 21 to realize the heating control of the first heating element 11 and the second heating element 13, respectively.

[0080] Under the action of the first pin 21 and the second pin 22, the first heating element 11 and the second heating element 13 are connected in parallel through the first connector 12. Accordingly, in use, when the heating element 10 is electrically connected through both first pins 21, the overall resistance of the heating element 10 is at its lowest; when the heating element 10 is electrically connected to the second pin 22 through one of the first pins 21, only the first heating element 11 or the second heating element 13 is energized, and the resistance of the heating element 10 is relatively increased. With a constant energizing voltage, the smaller the resistance connected in the circuit, the higher its heating power.

[0081] In this embodiment, the heating element 10 has the highest heating power when it is connected to the circuit through two first pins 21. When the heating element 10 is connected to the circuit through a combination of a first pin 21 and a second pin 22, its heating power depends on the resistance of a certain region under energized conditions. Since the resistance values ​​of the first heating element 11 and the second heating element 13 are different, the heating power of the first heating element 11 when connected to the circuit is different from that of the second heating element 13 when connected to the circuit.

[0082] When the heating element 10 is working, the heat generated is directly transferred to the first liquid guiding component 20 connected to it. The first liquid guiding component 20 can be located between the first heating element 11 and the second heating element 13. Therefore, by adjusting the pin 2 connected to the circuit of the heating element 10, the temperature of the first liquid guiding component 20 can be changed by adjusting the heating power. It is even possible to make different positions of the first liquid guiding component 20 have different temperatures, which can improve the potential problem of scorching in the first liquid guiding component 20 to a certain extent, thereby helping to improve the carbon buildup problem of the heating element 10.

[0083] It should be noted that the first pin 21 and the second pin 22 are both located on the same side of the heating element 1. Of course, in other similar embodiments, the first pin 21 and the second pin 22 can be adjusted to be located on opposite sides of the heating element 1, depending on the actual installation space requirements.

[0084] In other similar embodiments, the heating element 10 can also be configured as a columnar or approximately columnar C-shaped sheet structure (also referred to as an arc-shaped sheet structure). Please refer to [link to relevant documentation]. Figure 2 and Figure 3 The heating element 10 is arranged in a tubular structure with the second connector 14 and the first connector 12 close to each other. Along the circumference of the tubular structure, the first connector 12 and the second connector 14 are located at opposite ends of the heating element 1. Along the radial direction of the tubular structure, the first heating element 11 is located inside the second heating element 13. Correspondingly, along the circumference of the tubular structure, the length of the first heating element 11 (i.e., the length of the arcuate structure connecting the first end 111 and the second end 112) is less than the length of the second heating element 13 (i.e., the length of the arcuate structure connecting the third end 131 and the fourth end 132).

[0085] Specifically, the tubular structure has an axially penetrating notch in its circumferential direction; please refer to [reference needed]. Figure 3 and Figure 4 The second connector 14 and the first connector 12 are located on opposite sides of the notch in the circumferential direction and do not contact each other.

[0086] Please see Figure 2 , Figure 3 and Figure 4 In the tubular structure formed by the winding of the heating element 10, a hollow channel communicating with the atomization channel is formed inside. The first heating element 11 located on the inner side is close to the hollow channel, and correspondingly, the second heating element 13 is farther away from the hollow channel relative to the first heating element 11. When the atomizing core 100 is installed in the atomizing device, the aerosol forming matrix adsorbed by the first liquid guiding element 20 can generate aerosol under the heating action of the heating element 10. The generated aerosol enters the atomization channel through the hollow channel and finally flows to the nozzle communicating with the atomization channel.

[0087] Please see Figure 2 and Figure 5 After the heating element 10 is wound to form a tubular structure, the first liquid guiding element 20 is located between the first heating element 11 and the second heating element 13, and the two opposite sides of the first liquid guiding element 20 can respectively cooperate with the first heating element 11 and the second heating element 13 so that the first heating element 11 and the second heating element 13 can respectively heat different positions of the first liquid guiding element 20.

[0088] When both the first heating element 11 and the second heating element 13 are energized, the heating power of the first heating element 11 is greater than that of the second heating element 13. Therefore, the aerosol forming matrix can be preheated by the second heating element 13 to enhance its fluidity on the first liquid guide 20, and then flow along the first liquid guide 20 to the first heating element 11, where it is atomized under the heating action of the first heating element 11. The above structure can effectively reduce the probability of core clogging in the heating part 1, and can also reduce the probability of core clogging in the related liquid guide or storage structures in contact with the heating part 1, ultimately improving the performance and service life of the heating element 10.

[0089] Please see Figure 2 and Figure 3 The first pin 21 and the second pin 22 are located on the same side of the tubular heating part 1 and extend in the same direction along the axial direction of the tubular heating part 1. The heating part 1 is wound into... Figure 2 and Figure 3 Under the structure shown, the second pin 22 and the two first pins 21 remain in contact with each other at all times.

[0090] Please see Figure 4 Along the axial direction of the heating element 10, the cross-sectional area of ​​the first pin 21 connected to the first heating element 11 is smaller than the cross-sectional area of ​​the second pin 22 connected to the second heating element 13.

[0091] The cross-sectional area (or end face area) of the second pin 22 connected to the first connector 12 is smaller than the cross-sectional area of ​​the first pin 21 connected to the second heating element 13; correspondingly, the cross-sectional area of ​​the second pin 22 connected to the first connector 12 is larger than the cross-sectional area of ​​the first pin 21 connected to the first heating element 11.

[0092] It is understood that the atomizing core 100 provided in this application embodiment can utilize heating elements 10 with first heating elements 11 and second heating elements 13 arranged at intervals and with different resistance values ​​to preheat and heat the aerosol forming matrix in the first liquid guiding element 20 at different positions, so as to improve the carbon buildup problem of the atomizing core 100, improve the performance and service life of the atomizing core 100, and at the same time, it can also improve the problem of burnt core caused by dry burning of the atomizing core 100 to a certain extent.

[0093] The atomizing core 100 also includes a fixing member 50. The atomizing core 100 is generally a tubular structure, wherein the heating element 10 is bent to bring the second connector 14 and the first connector 12 close to each other, forming a tubular structure with a notch. The fixing member 50 is at least one and is mounted axially at the end of the heating part 1 along the axial direction of the tubular structure.

[0094] Please see Figure 6 and Figure 7 Two fasteners 50 are installed at both ends of the heating element 1 along the axial direction of the tubular structure. The fasteners 50 are arc-shaped structures with notches, also known as C-shaped structures. The end of the fastener 50 that contacts the heating element 1 is recessed inward to fix and limit the heating element 1 and the first liquid guide 20. Simultaneously, its notch faces the opening of the tubular heating element 1, and along the axial direction of the tubular structure, the width of the notch is greater than the width of the opening, allowing the fastener 50 to better avoid the pins 2 of the heating element 10. Furthermore, the notch structure also helps reduce the assembly difficulty of the fasteners 50.

[0095] The fixing member 50 can limit and fix the heating element 10 and the first liquid guiding member 20 in the axial direction to prevent axial displacement between the first liquid guiding member 20 and the heating element 10. In addition, the fixing member 50 can also provide better fixation and support for the heating element 10 to prevent defects such as deformation of the first heating element 11 and / or the second heating element 13 in the heating element 10 during assembly.

[0096] When the atomizing core 100 with the fixing member 50 is installed in the atomizing device, the fixing member 50 can also play a certain sealing role in the axial direction of the first liquid guiding member 20, so as to improve the leakage defects that may occur in the axial direction of the atomizing core 100.

[0097] It should be noted that the aforementioned fastener 50 is made of insulating material.

[0098] In other similar embodiments, the aforementioned fastener 50 may also be an O-type structure; please refer to [reference needed]. Figure 8 and Figure 9 .

[0099] Specifically, there are two fixing members 50, both of which are hollow annular structures. Similarly, the fixing members 50 have recessed portions that contact the ends of the heating element 1 and the first liquid guiding element 20, thereby fixing and limiting the heating element 1 and the first liquid guiding element 20. It should be noted that one of the fixing members 50 has a through hole for the pin 2 to pass through. Figure 9 Taking the shown orientation as an example, the lower fixing member 50 has three through holes for the pins 2 to pass through. The pins 2 of the heating element 10 pass through the through holes and connect to the fixing member 50. The upper fixing member 50 may not have the above-mentioned through holes; please refer to [link / reference]. Figure 9 Of course, considering processing costs, all O-ring fasteners 50 can also be provided with perforations, and the perforations do not affect the overall strength of the fasteners 50.

[0100] In other embodiments, the atomizing core 100 also includes an atomizing bracket 30, see [link to relevant documentation]. Figure 10 and Figure 11 The atomizing bracket 30 is a hollow columnar structure. The heating element 10, which is wound into a tubular structure, is installed inside the atomizing bracket 30, and there is a gap 301 between the outer wall of the heating element 10 and the inner wall of the atomizing bracket 30.

[0101] The aforementioned interval 301 prevents the heating element 10 from directly contacting the inner wall of the atomizing bracket 30.

[0102] In some embodiments, the outer peripheral sidewall of the fixing member 50 fits precisely with the inner sidewall of the atomizing bracket 30. The heating element 10 can be installed inside the atomizing bracket 30 by blocking the aforementioned gap 301 under the fixing action of the fixing member 50.

[0103] In other similar embodiments, the atomizing core 100 further includes a second liquid guiding member 40, which at least partially fills the aforementioned gap 301, thereby enabling the heating element 10 and the first liquid guiding member 20 to be securely mounted within the atomizing bracket 30 to a certain extent.

[0104] The second liquid guiding element 40, which is at least partially located within the interval 301, can contact the first liquid guiding element 20 through the second mesh 133 formed on the second heating element 13.

[0105] At least a portion of the aerosol-forming matrix adsorbed within the second liquid guiding element 40 can flow to the first liquid guiding element 20. When the second heating element 13 is in an energized heating state, the flow rate of the aerosol-forming matrix located within the second liquid guiding element 40 can be further enhanced.

[0106] Specifically, when both the first heating element 11 and the second heating element 13 in the heating element 10 are in an electrically heated state, during this process, as aerosols are continuously generated, the aerosol forming matrix located outside the atomizing support 30 can continuously flow to the first liquid guiding element 20 through the second liquid guiding element 40, thereby replenishing the aerosol forming matrix within the first liquid guiding element 20. Simultaneously, as aerosols are continuously generated, the aerosol forming matrix located within the first liquid guiding element 20 can be preheated at the second heating element 13 and flow towards the first heating element 11, helping to mitigate the risk of core clogging due to insufficient aerosol forming matrix supply at the contact point between the first liquid guiding element 20 and the first heating element 11.

[0107] Specifically, the material of the second liquid guiding component 40 can be the same as that of the first liquid guiding component 20. Of course, the second liquid guiding component 40 can also be made of materials such as non-woven fabric or organic cotton.

[0108] Please see Figure 10 and Figure 11 The aforementioned atomizing support 30 has a through-flow window (not shown in the figure) on its circumferential side wall. When the atomizing core 100 is installed in the atomizing device, the aerosol forming matrix located in the atomizing device can flow to the second liquid guiding component 40 through the aforementioned flow window to replenish the aerosol forming matrix in the second liquid guiding component 40.

[0109] The aforementioned second liquid guiding element 40 can be a single-layer structure or a double-layer structure located within the atomizing support 30. Alternatively, a portion of the second liquid guiding element 40 can extend beyond the atomizing support 30 through a flow guide window to further adsorb and guide the aerosol forming matrix located outside the atomizing support 30 to flow through the second liquid guiding element 40 to the first liquid guiding element 20.

[0110] It is understood that the atomizing core 100 provided in this embodiment can improve the movement rate of the aerosol forming matrix within the first liquid guiding component 20, thereby improving the problems of easy carbon buildup, easy clogging, and short service life of the atomizing core 100, and effectively improving the performance of the atomizing core 100.

[0111] In a second aspect, this application provides an atomizing device, including an atomizing core 100 and a power supply module. The atomizing core 100 is the atomizing core 100 described above, and the power supply module is electrically connected to the atomizing core 100 for supplying power to the heating element 10 of the atomizing core 100.

[0112] Specifically, the power supply module can be electrically connected to the atomizer core 100 via pin 2.

[0113] In some embodiments, the power supply module includes an electrically connected battery and a charging interface. The atomizing device also includes control circuitry.

[0114] When the atomizing device is working, the power supply module, under the control of the control circuit, supplies a certain amount of electrical energy to the heating element 10 of the atomizing core 100. The heating element 10 generates heat, which acts on the first liquid guiding element 20, and generates aerosol. The user can expel the aerosol from the atomizing device through the atomizing channel by drawing in a mouthpiece that is the same as the atomizing channel.

[0115] The atomizing device also includes a liquid storage structure for storing the aerosol forming matrix. The atomizing core 100 is connected to the liquid storage structure, so that the aerosol forming matrix located in the liquid storage structure can flow to the first liquid guiding element 20 through the second liquid guiding element 40.

[0116] Specifically, the liquid storage structure can include a liquid-absorbing component that adsorbs a certain amount of aerosol-forming matrix; this component can be absorbent cotton. The aerosol-forming matrix is ​​adsorbed within the liquid-absorbing component, which better prevents leakage. The atomizing core 100 is inserted through the middle of the liquid-absorbing component.

[0117] Of course, other shell-like structures can also be used to construct the liquid storage structure. Those skilled in the art should understand that the assembly structure and shape of the components in the atomizing device can be referenced from existing structures in related technologies, and will not be described in detail in this application.

[0118] It is understood that the atomizing device provided in the embodiments of this application includes the beneficial effects of any one or more of the atomizing cores 100 described above, which will not be repeated here.

[0119] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0120] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
