Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to a heating component and an atomization device. Background Technology

[0002] Currently, in heated non-combustible atomizing devices using a central heating method, a central heating needle or column is typically installed in the heating chamber. When the aerosol generating rod is inserted into the heating chamber, the central heating needle or column penetrates the interior of the aerosol generating rod to heat the atomizing matrix within the rod. Commonly, the central heating needle or column uses a cylindrical shell with a heating wire inside. Heating is achieved by energizing the heating wire. Typically, it takes 15 to 20 seconds for the central heating needle or column to reach the preheating temperature. This long preheating time results in a poor user experience, requiring users to wait a considerable amount of time before normal operation. Utility Model Content

[0035] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0038] An aerosol generator is a special atomizing product containing an atomizing matrix. When in use, it is inserted into a matching heated non-combustible atomizing device. The heater heats the aerosol generator, causing the atomizing matrix inside the aerosol generator to atomize and generate an aerosol. As the user draws the aerosol generator, the aerosol moves with the airflow to the suction end.

[0039] The heating component provided in this application allows at least a portion of the heating component to penetrate the interior of the aerosol generating rod when it is installed in a matching atomizing device, thereby heating the aerosol generating rod. The heating component employs a dual heating structure combining a first heating element and a second heating element. Both the first and second heating elements are electrically connected to the power supply component of the atomizing device to increase the heat output of the heating component, reduce preheating time, and enable the heating component to quickly reach the target temperature.

[0040] The following describes some embodiments of the heating components and atomizing devices provided in this application with reference to the accompanying drawings.

[0041] The first aspect of this application provides a heating assembly 100, such as... Figure 1 , Figure 2 ,and Figure 3 As shown, the heating assembly 100 includes a heat-conducting element 1, a first heating element 2, and a second heating element 3. The heat-conducting element 1 serves as the base of the heating assembly 100, extending along a first direction. The heat-conducting element 1 has a mounting cavity 11 extending along the first direction, and one end of the mounting cavity 11 in the first direction has a connecting port 111. The first heating element 2 is disposed within the mounting cavity 11 and is positioned along the first direction. The second heating element 3 is connected to the outer surface of the heat-conducting element 1. Both the first heating element 2 and the second heating element 3 are electrically connected to the power supply assembly 530 and generate heat when energized, thereby heating the heat-conducting element 1 from its interior and exterior, respectively. When applied in an atomizing device, the heat-conducting element 1 can penetrate into the aerosol generating rod and conduct heat to the aerosol generating rod through the heat-conducting element 1, thus heating the aerosol generating rod.

[0042] The first heating element 2 and the second heating element 3 can work independently. During use, the first heating element 2 and the second heating element 3 can be turned on simultaneously as needed, or only one of them can be turned on. At different stages of user use, the first heating element 2 and the second heating element 3 can be adjusted according to different temperature requirements. For example, during the preheating stage after the device is started, the first heating element 2 and the second heating element 3 can be turned on simultaneously. When the target temperature is reached (for example, after the first suction), one of the heating elements can be turned off, and only the other heating element can work, thereby meeting the temperature requirements at different stages.

[0043] It is understandable that in existing heat-not-burn atomizing devices that use central heating, the heater usually has a heating wire inside the shell. However, this type of heater heats up slowly overall. After the device is started, it usually needs to preheat for 15 to 20 seconds to reach the target temperature. After that, the atomizing matrix in the aerosol generating rod is heated and atomized to generate aerosol, which results in a long waiting time for the user.

[0044] In this embodiment, the heating component, through structural improvements and optimizations, has heating elements set both inside and outside the heat-conducting component 1, forming a dual heating mode. This allows it to quickly reach the preheating temperature upon startup, enabling the atomizing matrix of the aerosol generating rod to rapidly atomize and generate aerosols. This significantly reduces the preheating time, correspondingly shortening the user's waiting time and improving the user experience.

[0045] It should be noted that in practical applications, the shape of the heat-conducting component 1 is not limited to the columnar structure shown in the figure. It can also be set as a plate-like structure, prism structure or other structural forms that can meet the heating requirements as needed. The heat-conducting component 1 can be made of a material with good thermal conductivity, such as aluminum alloy.

[0046] In further embodiments of this application, such as Figures 1 to 3 As shown, in the heating assembly 100, the first heating element 2 has a first pin structure 21, and the second heating element 3 has a second pin structure 31. Both the first pin structure 21 and the second pin structure 31 can be electrically connected to the power supply assembly 530. The first pin structure 21 extends outward from the mounting cavity 11 through the communication port 111 to facilitate connection with the power supply assembly 530. The second pin structure 31 extends towards the heat guide element 1 near the communication port 111 to facilitate connection with the power supply assembly 530. The first pin structure 21 and the second pin structure 31 are independently configured and can each independently form an electrical connection with the power supply assembly 530, thus enabling the first heating element 2 and the second heating element 3 to form a parallel connection. In use, the power supply assembly 530 can supply power to the first heating element 2 alone, the second heating element 3 alone, or simultaneously to both heating elements 2 and 3 to meet the temperature requirements of different usage stages.

[0047] It should be noted that, in practical applications, the number of the first pin structure 21 and the second pin structure 31 is not limited to the following. Figure 1 and Figure 2 The two shown can be set to other quantities than two; or, one or more of the first heating element 2 and the second heating element 3 can be set, which can be set according to actual needs.

[0048] Furthermore, in a specific implementation, such as Figure 3 , Figure 4 , Figure 5 and Figure 6In the example, the first heating element 2 includes a spiral segment 22 and a straight segment 23. The spiral segment 22 extends spirally along a first direction, and one end of the spiral segment 22 extends out of the communication port 111 to form one of the first pin structures 21 for connecting the power supply component 530. The straight segment 23 extends along the first direction and passes through the inner side of the spiral segment 22. One end of the straight segment 23 extends out of the communication port 111 to form another first pin structure 21 for connecting the power supply component 530. The other end of the straight segment 23 is connected to the end of the spiral segment 22 away from the communication port 111. The two first pin structures 21 are respectively connected to the positive and negative terminals of the power supply component 530 to form a power supply circuit, so that the first heating element 2 heats up when energized.

[0049] The straight segment 23 and the spiral segment 22 can be manufactured using the same heating resistance wire through an integral molding process, or they can be separate structures connected by a certain method (such as welding) to form an integral structure. In addition, the diameter and pitch of the spiral segment 22 can be set according to the actual heating requirements.

[0050] Furthermore, in a specific implementation, such as Figure 3 and Figure 4 In the example shown, a first gap exists between the spiral segment 22 of the first heating element 2 and the inner wall surface of the mounting cavity 11, so that the first heating element 2 does not directly contact the heat-conducting element 1, but conducts heat to the heat-conducting element 1 through thermal radiation. It can be understood that if the spiral segment 22 contacts the inner wall surface of the heat-conducting element 1, the temperature in the contact area is relatively high, while the temperature in the non-contact area is relatively low, easily leading to uneven heating, which is not conducive to the sufficient heating and atomization of the atomizing matrix. In this embodiment, by setting a non-contact state between the first heating element 2 and the inner wall surface of the mounting cavity 11 and maintaining the first gap, heat is conducted through thermal radiation, covering a relatively larger area, allowing the heat from the first heating element 2 to be conducted to the heat-conducting element 1 relatively evenly, which helps to alleviate the phenomenon of uneven heating.

[0051] In practical applications, the specific value of the first gap can be set according to the specific dimensions of the mounting cavity 11 and the spiral section 22. For example, the first gap can be set in the range of 10 mm to 25 mm. Preferably, the first gap can be set to 20 mm, which can simultaneously take into account the radiation range and heat conduction efficiency.

[0052] Furthermore, in a specific example, such as Figure 3 and Figure 4 In the example, the surfaces of the spiral segment 22 and the straight segment 23 of the first heating element 2 can be provided with an infrared radiation coating, which can effectively promote the infrared radiation effect during heating, increase the amount of infrared radiation, and help to further improve the heating efficiency.

[0053] Furthermore, in a specific example, such as Figure 3 and Figure 4 In the example, the surface of the first heating element 2 can be provided with an anti-oxidation coating, which can effectively improve the anti-oxidation ability, prevent the first heating element 2 from being affected by oxidation, and help enhance the heating effect and extend the service life.

[0054] Furthermore, in one specific embodiment, the spiral segment 22 and the straight segment 23 of the first heating element 2, and the mounting cavity 11 of the heat-conducting element 1 are coaxially arranged. That is, in the first direction, the central axis of the mounting cavity 11 coincides with the central axis of the spiral segment 22, and the straight segment 23 is located on the central axis. Through this arrangement, the heat radiation of the first heating element 2 is essentially consistent in any direction in the circumferential direction, and the heat conducted to the heat-conducting element 1 can be distributed relatively evenly. This is beneficial for enhancing the heating uniformity of the aerosol generating rod, allowing the atomizing matrix within the aerosol generating rod to be fully heated, thereby improving atomization efficiency.

[0055] In further embodiments of this application, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the heating assembly 100, the second heating element 3 includes a heating circuit 32, an electrical connection portion 33, and a second pin structure 31. The heating circuit 32 is wound around the outer wall of the heat-conducting element 1 and can generate heat when energized. The electrical connection portion 33 is located at both ends of the heating circuit 32, that is, each end of the heating circuit 32 is connected to an electrical connection portion 33, and each electrical connection portion 33 is connected to a second pin structure 31, so as to act as a relay connection between the heating circuit 32 and the second pin structure 31. The heating circuit 32 can be in the form of a printed circuit, or it can be in the form of a heating element, heating wire, etc.; the electrical connection portion 33 can be in the form of a solder pad to facilitate soldering of the second pin structure 31. When the heating assembly 100 is used in an atomizing device, the second pin structure 31 can be electrically connected to the power supply assembly 530 to energize the heating circuit 32 through the second pin structure 31 and the electrical connection portion 33.

[0056] The structure of the second heating element 3 in this embodiment allows the heating line 32 to be closely attached to the outer surface of the heat conductor 1, resulting in high heat conduction efficiency. Moreover, the heating line 32 has a small thickness, which does not significantly affect the overall shape and structure of the heat conductor 1, thereby preventing obstruction when the heat conductor 1 penetrates into the aerosol generating rod.

[0057] Furthermore, in a specific example, such as Figure 1 , Figure 5 and Figure 6In the example, at least a portion of the heating lines 32 of the second heating element 3 are arranged in a serpentine pattern on the outer wall of the heat-conducting element 1. That is, a portion of the heating lines 32 extends along the first direction (i.e., the axial direction of the heat-conducting element 1), and a portion extends along the circumferential direction of the heat-conducting element 1. The two portions are alternately arranged and connected sequentially, such as... Figure 5 and Figure 6 The arrangement shown is such that the heating circuit 32 can cover as much area as possible on the heat-conducting element 1, thereby increasing the heating range of the heat-conducting element 1. Furthermore, there is a certain interval between each part of the serpentine arrangement to disperse heat and avoid localized overheating. Preferably, as shown... Figure 5 and Figure 6 As shown, in the first direction, all line segments extending along the circumference of the heat conductor 1 in the serpentine portion of the heating line 32 are equally spaced. Correspondingly, in the circumferential direction of the heat conductor 1, all line segments extending along the first direction in the serpentine portion of the heating line 32 are equally spaced, so that the serpentine portion of the heating line 32 is arranged regularly in the first direction and the circumferential direction of the heat conductor 1, making the heat conductor 1 more evenly heated.

[0058] Furthermore, in a specific example, such as Figure 5 As shown, the two electrical connection portions 33 of the second heating element 3 are spaced apart in the circumferential direction of the heat-conducting element 1 to prevent crossover or contact between different segments of the heating circuit 32; and in the first direction, both electrical connection portions 33 are located near the communication port 111, close to the extension direction of the second pin structure 31, which can shorten the length of the second pin structure 31 and also avoid short circuit caused by contact between the second pin structure 31 and the heating circuit 32.

[0059] Furthermore, in a specific example, such as Figure 7 As shown, at least a portion of the heating circuit 32 of the second heating element 3 is arranged in a spiral shape, that is, the heating circuit 32 includes circuit segments that extend spirally along the outer wall of the heat-conducting element 1, for example... Figure 7 In the example shown, both ends of the heating line 32 are located near the connection port and connected to the corresponding electrical connection part 33; the spiral portion of the heating line 32 first extends spirally in a first direction away from the connection port 111, and then extends spirally in the opposite direction to cover the main area on the outer wall of the heat conductor 1, so that the heat conductor 1 can be heated more evenly. The spirally arranged heating line 32 is not limited to... Figure 7 The heating wire can also take the form of printed circuits or heating elements.

[0060] In further embodiments of this application, such as Figures 1 to 3In the example, in the heating assembly 100, in the first direction, the end of the heat-conducting element 1 away from the communication port 111 has a spike 12. The spike 12 is adapted to the overall structure of the heat-conducting element 1 so that when the aerosol generating rod is installed into the heating chamber of the atomizing device, the heat-conducting element 1 can be smoothly inserted into the interior of the aerosol generating rod through the spike 12, and the insertion process is relatively smooth, making it more convenient to use.

[0061] Furthermore, such as Figures 1 to 3 In the example, the heat-conducting element 1 specifically adopts a cylindrical structure so that when the aerosol generating rod is heated, the heat-conducting element 1 can conduct heat more uniformly in the circumferential direction. At the same time, the cylindrical structure can also be adapted to the spiral structure of the first heating element 2. Correspondingly, when the heat-conducting element 1 is a cylindrical structure, the spike 12 can adopt a conical structure to be adapted to the cylindrical structure.

[0062] In another specific example, such as Figure 8 In the example, the heat conductor 1 can also adopt a cylindrical structure, and in the first direction, the diameter of the heat conductor 1 gradually decreases in the direction away from the communication port 111, so that the heat conductor 1 has a structure that is smaller at the top and larger at the bottom, so that it can be more easily inserted into the interior of the aerosol generating rod.

[0063] Of course, the heat-conducting component 1 is not limited to the structural form in the above example. In practical applications, it can also be plate-shaped or other structural forms, as long as it can be adapted to the first heating component 2 and the second heating component 3 and can penetrate into the aerosol generating rod.

[0064] In further embodiments of this application, such as Figure 9 In the example shown, the heating assembly 100 also includes a support base 4. The support base 4 is correspondingly positioned to the end of the heat-conducting element 1 that has a communication port 111. In the first direction, the support base 4 has a mounting groove 41 at the end facing the heat-conducting element 1. The shape and size of the mounting groove 41 are adapted to the heat-conducting element 1. The end of the heat-conducting element 1 with the communication port 111 is inserted into the mounting groove 41 and connected and fixed to the support base 4, thereby supporting and fixing the heat-conducting element 1 and the first heating element 2. The end of the first heating element 2 that extends out of the communication port 111 is also inserted into the mounting groove 41 to support and fix the first heating element 2, thus eliminating the need for a separate fixing structure for the first heating element 2. When the heating assembly 100 is used in an atomizing device, it can also be assembled and connected to the bracket structure 513 inside the atomizing device through the support base 4 for fixation.

[0065] It should be noted that the shape of the support base 4 is not limited to... Figure 9The example shown can be specifically designed based on the mounting structure of the bracket structure 513 in the atomizing device. Additionally, the support base 4 can be provided with corresponding wire-passing holes for the first pin structure 21 and the second pin structure 31 to pass through. Preferably, the support base 4 can be made of a flexible material, such as silicone, which facilitates assembly, allowing the heat-conducting component 1 to form a sealed connection with the mounting groove 41 through an interference fit. Furthermore, it facilitates the passage of the first pin structure 21 and the second pin structure 31, avoids gaps, and provides a fixing function for the first pin structure 21 and the second pin structure 31.

[0066] An embodiment of the second aspect of this application provides an atomizing device 500, such as... Figure 10 , Figure 11 , Figure 12 As shown, the atomizing device 500 includes a main housing 510, a heating component 100 as described in any of the embodiments of the first aspect, and a power supply component 530. The main housing 510 serves as the mounting carrier for the atomizing device 500, and has an assembly port 511 at one end in the first direction. The main housing 510 has a heating chamber 521 inside, and the heating chamber 521 communicates with the assembly port 511. Both the heating component 100 and the power supply component 530 are disposed in the main housing 510. The heating component 100 is arranged along the first direction, and at least a portion of the heating component 100 is disposed in the heating cavity 521. The end of the heating component 100 away from the communication port 111 faces the assembly port 511 of the main housing 510, so that when the aerosol generating rod 600 is inserted into the heating cavity 521 through the assembly port 511, the heating component 100 can penetrate into the interior of the aerosol generating rod 600. The power supply component 530 is electrically connected to the first heating element 2 and the second heating element 3 of the heating component 100 to supply power to the first heating element 2 and / or the second heating element 3 and make it heat up, thereby conducting heat into the interior of the aerosol generating rod 600 through the heat conduction component 1 to achieve heating.

[0067] The following describes a specific example of the atomizing device 500 of this application with reference to the accompanying drawings.

[0068] like Figures 1 to 13 As shown, the atomizing device 500 is specifically a heat-not-burning device. The first direction of the main housing 510 is the height direction. At the top of the main housing 510 is an interface piece 514, the bottom of which connects to the mounting port 511, and the top of the interface piece 514 protrudes upwards. The interface piece 514 has a through opening for the aerosol generating rod 600 to pass through. The internal space of the main housing 510 is divided into different chambers, such as... Figure 12In the example, the left cavity has a heat insulation sleeve 512 and a support structure 513. The support structure 513 is fixedly connected to the bottom of the main housing 510. The heat insulation sleeve 512 is sleeved on the top of the support structure 513 and connected to the inner top wall of the main housing 510. The heat insulation sleeve 512 is correspondingly provided with the assembly port 511 and the interface piece 514, and together with the support structure 513, they form a cavity in which the heating component 100 is located. The top of the support structure 513 has a mounting hole 5131. The support base 4 of the heating component 100 is provided in the mounting hole 5131 and is sealed to the inner wall of the mounting hole 5131. A heating sleeve 520 is provided above the support base 4. The bottom of the heating sleeve 520 has a heating port 522, and the top of the heating sleeve 520 extends through the assembly port 511 and into the interface piece 514. The top of the heating sleeve 520 is also through. The heat-conducting element 1 of the heating assembly 100 passes through the heating port 522 along the first direction and extends into the heating chamber 521. The heat-conducting element 1 is coaxially arranged with the heating port 522 and the heating chamber 521, and the diameter of the heating port 522 is larger than the diameter of the heat-conducting element 1 of the heating assembly 100. The top end of the heat-conducting element 1 has a conical spike 12. When the aerosol generating rod 600 passes through the interface 514 and is inserted into the heating chamber 521, the heat-conducting element 1 is transferred from the bottom of the aerosol generating rod 600 into the interior of the aerosol generating rod 600 to heat the aerosol generating rod 600.

[0069] like Figures 1 to 3 as well as Figure 12 As shown, the first heating element 2 of the heating assembly 100 is specifically in the form of a heating wire. The first heating element 2 includes a straight segment 23 and a spiral segment 22 connected to each other. The spiral segment 22 extends spirally in a first direction, and the straight segment 23 passes through the inner side of the spiral segment 22 in the first direction. One end of the straight segment 23 and one end of the spiral segment 22 respectively extend downward through the support base 4 to form two first pin structures 21. The second heating element 3 is in the form of a printed circuit and is connected to the outer wall of the heat-conducting component 1. The second heating element 3 specifically includes a serpentine heating circuit 32, two electrical connection parts 33, and two second pin structures 31. The heating circuit 32 first extends in the first direction away from the communication port 111, and then extends in the direction closer to the communication port 111, so that both ends of the heating circuit 32 are located close to the communication port 111 and are respectively connected to an electrical connection part 33. Each electrical connection part 33 is connected to a second pin structure 31. The second pin structure 31 extends downward through the support base 4 to connect to the power supply assembly 530.

[0070] like Figure 12 and Figure 13In the example, the outer wall of the heating sleeve 520 is provided with a plurality of first snap-fit ​​structures 523 and a plurality of third snap-fit ​​structures 524, with the plurality of first snap-fit ​​structures 523 located above the plurality of third snap-fit ​​structures 524; the first snap-fit ​​structures 523 are specifically in the form of snap fasteners, and the plurality of first snap-fit ​​structures 523 are spaced apart circumferentially; the third snap-fit ​​structures 524 are in the form of snap protrusions, and the plurality of third snap-fit ​​structures 524 are spaced apart circumferentially. The first snap-fit ​​structures 523 correspond to the inner wall of the interface member 514, and the inner wall of the interface member 514 is provided with a plurality of second snap-fit ​​structures 5141, the second snap-fit ​​structures 5141 are specifically in the form of slots, and are spaced apart circumferentially to correspond to the first snap-fit ​​structures 523, with each first snap-fit ​​structure 523 snapping into a corresponding second snap-fit ​​structure 5141. Similarly, the third snap-fit ​​structure 524 corresponds to the inner wall of the heat insulation sleeve 512. The inner wall of the heat insulation sleeve 512 has multiple fourth snap-fit ​​structures 5121, which also adopt a snap-fit ​​form and engage with the corresponding third snap-fit ​​structure 524. The top end of the heating sleeve 520 abuts against the inner top wall of the interface piece 514. Combined with the snap-fit ​​engagement of the first snap-fit ​​structure 523 and the second snap-fit ​​structure 5141, and the snap-fit ​​engagement of the third snap-fit ​​structure 524 and the fourth snap-fit ​​structure 5121, the heating sleeve 520 is assembled and fixed, and is easy to disassemble. An air inlet 515 is provided at the joint between the interface component 514 and the assembly port 511. The air inlet 515 is connected to the interior of the heat insulation sleeve 512. There is a certain gap between the bottom of the heat insulation sleeve 512 and the support seat 4 of the heating component 100. External air can flow into the interior of the heat insulation sleeve 512 through the air inlet 515 and into the aerosol generating rod 600 in the heating chamber 521 through the heating port 522 at the bottom of the heat insulation sleeve 512. It then mixes with the aerosol generated by the atomizing matrix and flows towards the suction end of the aerosol generating rod 600.

[0071] The power supply assembly 530 includes a battery 531 and an electronic control board 532 electrically connected to each other. The electronic control board 532 is equipped with a control circuit and is located at the bottom of the main housing 510. The battery 531 is located on one side of the heating assembly 100 and is electrically connected to the first pin structure 21 and the second pin structure 31 respectively. The first heating element 2 and the second heating element 3 are connected in parallel, and the power supply state of the battery 531 to the first heating element 2 and the second heating element 3 is controlled by the electronic control board 532.

[0072] During use, when the atomizing device 500 is first started, the heating component 100 is in the preheating stage. At this time, the first heating element 2 and the second heating element 3 can be turned on simultaneously to increase the heat generation and allow the heating component 100 to quickly reach the target temperature, so that the atomizing matrix inside the aerosol generating rod 600 can be rapidly atomized and generate aerosol. Afterward, after the user completes at least one suction action, the heating component 100 enters the normal heating stage. At this time, the second heating element 3 can be turned off and the first heating element 2 can be heated alone, or the first heating element 2 can be turned off and the second heating element 3 can be heated alone, thus meeting the heating and atomization requirements of the atomizing matrix. It can be understood that the above process can be achieved through conventional control operations.

[0073] In this embodiment, the atomizing device 500 has heating elements both inside and outside the heat-conducting component 1, forming a dual heating method. This allows for rapid reaching of the preheating temperature upon startup, enabling the atomizing matrix of the aerosol generating rod 600 to be rapidly atomized and generate aerosols. This significantly reduces preheating time, correspondingly shortening user waiting time. Furthermore, during the normal heating phase, only one heating element can be used, thereby reducing energy consumption and preventing overheating that could cause burns, thus improving the user experience.

[0074] Furthermore, the atomizing device 500 in this embodiment also has all the beneficial effects of the heating component 100 in any of the above embodiments, which will not be repeated here.

[0075] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
