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, circumferential heating is one of the more common heating methods in heated non-combustible atomization devices. In devices using circumferential heating, thick-film resistors are typically printed on the sidewall of the tube. By controlling the heating of the thick-film resistors, heat is conducted to the tube, thereby heating the aerosol generating rod inserted into the tube, bringing the internal atomizing matrix to its atomization temperature. However, in the above heating structure, the process of printing thick-film resistors is relatively complex, the yield rate is difficult to improve, and the processing cost is high. Moreover, due to the limited layout of the printed thick-film resistors, uneven heating is inevitable, easily causing localized severe baking or over-baking, affecting the user experience.

[0008] In a further embodiment of this application, each support layer includes the same number of support structures, and in any adjacent support layers, the support structures are spaced at the same angle in the circumferential direction.
[0009] In a further embodiment of this application, the number of support layers is n, and any two adjacent support layers are separated by a first phase angle a1 in the circumferential direction, where a1 = 180° / (n-1).

[0036] 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.
[0037] The heating component provided in this application uses a heating tube made of a light-transmitting material that allows infrared rays to pass through. The heating element is supported by multiple support layers formed by a support structure on the outer wall of the heating tube, so that the heating element is wound around the heating tube in the circumferential and axial directions. When the heating element heats up in the power-on state, it can radiate infrared rays into the interior of the heating tube, so that the aerosol generating rod inserted into the heating tube is heated more evenly, preventing local severe baking or over-baking.
[0038] The following describes some embodiments of the heating components and atomizing devices provided in this application with reference to the accompanying drawings.
[0039] The first aspect of this application provides a heating assembly 100, such as... Figure 1 , Figure 2 As shown, the heating assembly 100 includes a heating tube 1 and a heating element 2. The heating tube 1 is made of a light-transmitting material, allowing infrared light to pass through. The heating tube 1 has a receiving cavity 11 for accommodating an aerosol generating rod 500. In a first direction, one end of the receiving cavity 11 has an insertion port 111 for inserting the aerosol generating rod 500 into the receiving cavity 11 through the insertion port 111. A plurality of support structures 1121 are provided on the outer wall of the heating tube 1, and a plurality of support layers 112 are formed at intervals in the first direction. Each support layer 112 includes a plurality of support structures 1121 spaced apart in the circumferential direction. Correspondingly, the heating element 2 is arranged around the outside of the heating tube 1, and the heating element 2 is supported on the support structures 1121 of the plurality of support layers 112, so as to support and fix the heating element 2 through the support structures 1121. When the heating component 100 is applied in the atomizing device 400, the heating element can be electrically connected to the power supply component of the atomizing device 400, so that the power supply component can supply power to the heating element, causing the heating element to generate heat and radiate infrared rays. The infrared rays can penetrate the heating tube 1 and enter the receiving cavity 11 to infrared heat the aerosol generating rod 500. In particular, since the infrared rays have a wide propagation area, they can cover all areas in the receiving cavity 11. Combined with the heat conduction effect of the heating tube 1, a relatively uniform heating effect can be formed on the aerosol generating rod 500 in the receiving cavity 11.
[0040] It is understandable that existing atomizing devices typically use thick-film resistors printed on the sidewalls of a metal tube as heating elements, and conduct heat to the aerosol generating rod inside the metal tube. However, the process of printing thick-film resistors is relatively complex, and uneven heat distribution is inevitable on the metal tube, affecting the uniformity of heating the aerosol generating rod. In existing atomizing devices that use infrared heating, the infrared heating element is usually arranged in the vacuum cavity of the heating tube. Under high temperature, the heating element is prone to deformation, collapse, displacement and other phenomena.
[0041] In this embodiment, the heating component 100, through structural improvements and optimizations, utilizes a heating element 2 wrapped around the outside of a light-transmitting heating tube 1, and is supported by a support structure 1121 on the outer wall of the heating tube 1. The heating element 2 can generate heat when energized and radiate infrared rays into the interior of the heating tube 1, making the aerosol generating rod 500 contained in the heating tube 1 more evenly heated. This helps prevent localized severe baking or over-baking, improves the user experience, and has a relatively simple structure. It does not require printing thick-film resistors or setting up a vacuum cavity, which avoids deformation, collapse, displacement, etc. caused by installing the heating element 2 in a vacuum cavity. This effectively reduces the difficulty of processing and manufacturing, and helps reduce manufacturing costs.
[0042] It should be noted that, in practical applications, the shape and size of the insertion port 111 and the receiving cavity 11 of the heating element 1 are adapted to the corresponding aerosol generating rod 500. The specific winding method of the heating element 2 can be set according to actual usage needs, while the number and setting position of the support layer 112 and the support structure 1121 can be set according to the winding method of the heating element, thereby meeting the heating requirements.
[0043] Specifically, the heating element 1 can be made of quartz or other ceramic materials that can transmit infrared light; the heating element 2 can be made of materials such as tungsten, nickel-chromium, titanium, iron-chromium-aluminum, etc.
[0044] In further embodiments of this application, such as Figures 1 to 3 As shown, the heating element 2 specifically includes a lead segment 21, a flat segment 22, and a spiral segment 23. The two ends of the heating element 2 are lead segments 21, which extend outward from the heating tube 1 for connection to the power supply component. Between two lead segments 21, multiple flat segments 22 and multiple spiral segments 23 are alternately arranged in the extending direction; the flat segments 22 extend circumferentially along the heating tube 1, and each flat segment 22 abuts against multiple support structures 1121 of a corresponding support layer 112 to form multi-point support; the spiral segments 23 extend spirally in the first direction, and their two ends are respectively connected to two adjacent flat segments 22; each lead segment 21 is connected to an adjacent flat segment 22 or spiral segment 23 to form the overall heating element 2 structure.
[0045] It should be noted that, in practical applications, the number of heating elements 2 is not limited to... Figure 1 The heating element 2 shown is one type, but multiple heating elements 2 can be provided as needed; the heating element 2 can be a one-piece molded structure or a split structure connected together.
[0046] Furthermore, in a specific implementation, such as Figures 1 to 3In the example shown, in the circumferential direction of the heating element 1, each flat segment 22 of the heating element 2 abuts against each support structure 1121 in the corresponding support layer 112 to further increase the number of support points. In each support layer 112, at least one support structure 1121 is located in a first direction on the side of the corresponding flat segment 22 away from the insertion port 111, i.e., between a corresponding set of flat segments 22 and the support layer 112. At least a portion of the support structure 1121 can provide support to the flat segment 22 from the side away from the insertion port 111, so that when the insertion port 111 is facing upwards, the support structure 1121 located below the flat segment 22 can provide effective support to the heating element 2.
[0047] It should be noted that among the multiple support structures 1121 of each support layer 112, some support structures 1121 may be located on the side of the corresponding flat section 22 away from the insertion port 111, or all support structures 1121 may be located on the side of the corresponding flat section 22 away from the insertion port 111.
[0048] In further embodiments of this application, such as Figure 1 , Figure 4 and Figure 5 In the example shown, on the projection plane perpendicular to the first direction, the support structures 1121 in adjacent support layers 112 are staggered circumferentially, so that the contact points between the flat section 22 and the corresponding support structure 1121 are spaced at a certain angle in the circumferential direction. This allows the heating element 2 as a whole to be supported and fixed at different positions in the circumferential direction, with relatively dispersed stress points and stronger stability. The spacing angle formed by the circumferential stagger of different support layers 112 can be set according to the number and size of the support layers 112 and support structures 1121.
[0049] Furthermore, in one specific embodiment, such as Figure 4 and Figure 5 In the example, the number of support structures 1121 in each support layer 112 is the same, and the circumferential spacing angle is the same. That is, the structural form of adjacent support layers 112 and the distribution of support structures 1121 are the same. The difference is that adjacent support layers 112 are misaligned in the circumferential direction and form a certain spacing angle.
[0050] Furthermore, such as Figure 3 and Figure 4 In the example, when the number of support layers 112 provided in the first direction of the heating tube 1 is n, the first phase angle formed by the circumferential misalignment of any two adjacent support layers 112 is a1, and the number of support layers 112 n and the first phase angle a1 satisfy the correspondence of a1 = 180° / (n-1). Figure 3 and Figure 4For example, the number of support layers 112 is 5, and each support layer 112 includes 3 support structures 1121. The 3 support structures 1121 are equally spaced along the circumference of the heating tube 1, that is, any two adjacent support structures 1121 are spaced 120° apart in the circumferential direction. Then the first phase angle a1 formed by the misalignment between adjacent support layers 112 is a1 = a1 = 180° / (5-1) = 45°. Through the arrangement of the support structures 1121 in this embodiment, different support layers 112 can form a relatively smooth spiral shape in the first direction, and be equally spaced in the circumferential direction. This not only makes the overall force distribution of the heating element 2 more uniform, but also allows the multiple spiral segments 23 of the heating element 2 to form a continuous and relatively smooth direction, which is convenient for wiring, thus reducing the bending area and improving the conductivity and heating performance.
[0051] In further embodiments of this application, such as Figure 1 , Figure 6 and Figure 7 As shown, in another specific implementation, the heating element 1 can be divided into two symmetrical semicircular structures in the circumferential direction, and adjacent support layers 112 are respectively set in different semicircular structures, and are centrally symmetrical with respect to the central axis of the heating element 1. That is, all support structures 1121 of each support layer 112 are located within 180° of the heating element 1 in the circumferential direction, and two adjacent support layers 112 are offset in the circumferential direction and differ by a second phase angle α2 of 180°. Figure 6 and Figure 7 For example, each support layer 112 includes three support structures 1121. The three support structures 1121 are equally spaced within a 180° range in the circumferential direction, that is, two adjacent support structures 1121 in the circumferential direction are spaced 90° apart. On the projection plane perpendicular to the first direction, the support structures 1121 located at the two connection points of the semicircular structure in the multiple support layers 112 overlap, while the support structure 1121 located in the middle of the semicircular structure alternates between the two semicircular structures. Correspondingly, the flat section 22 of the heating element 2 can only cover the corresponding part of the heating tube 1 in the circumferential direction, that is, it is connected to the spiral section 23. For example, in the circumferential direction, the flat section 22 covers a 180° range, while the spiral section 23 covers a 360° range, so that the spiral section 23 can be connected to the flat section 22 in the two semicircular structures respectively, and maintain a relatively smooth spiral curve state.
[0052] It should be noted that the above are only some preferred examples in this application. In actual applications, the heating element 2 can be set according to specific usage needs, and its winding method is not limited to the method in the above examples.
[0053] In further embodiments of this application, such as Figure 1 , Figure 8 and Figure 9 As shown, the support structure 1121 can be a protruding post, a protruding block, or a boss, and can be set according to parameters such as the size and weight of the heating element 2 to meet the support requirements of the heating element 2. For example, when the heating element 2 uses a heating wire with a small diameter, the corresponding support structure 1121 can be in the form of a protruding post, such as... Figure 3 Examples; when the heating element 2 uses a heating plate or heating strip with a slightly larger width, the corresponding support structure 1121 can be in the form of a protrusion or a boss, such as... Figure 9 Examples are shown in the text. In practical applications, multiple different forms of support structures 1121 can be used simultaneously, for example... Figure 8 In the example, some support structures 1121 can be configured to use protruding columns, while other support structures 1121 can use protrusions or bosses, forming different forms of support structures 1121 that are matched together to further improve the support and fixation effect.
[0054] Furthermore, such as Figure 8 In the example, five support layers 112 are arranged on the outer wall of the heating element 1 along a first direction. Each support layer 112 includes three support structures 1121. The three support structures 1121 adopt the same structural form and are evenly spaced in the circumferential direction. The structural forms of the support structures 1121 in adjacent support layers 112 are different, for example... Figure 7 In the state shown, in any two adjacent support layers 112 in the first direction, the support structure 1121 in one support layer 112 is in the form of a boss, and the support structure 1121 in the other support layer 112 is in the form of a column; moreover, any two adjacent support layers 112 are 45° out of phase in the circumferential direction.
[0055] Furthermore, such as Figure 9 In the example, five support layers 112 are provided on the outer wall of the heating tube 1 along the first direction. Each support layer 112 includes three support structures 1121. All three support structures 1121 are in the form of bosses and are equally spaced in the circumferential direction. The support structures 1121 in any two adjacent support layers 112 are in the same form, which are all bosses, but the two adjacent support layers 112 are 45° out of phase in the circumferential direction.
[0056] In further embodiments of this application, such as Figure 1 and Figure 10In the example, the support structure 1121 also has a limiting structure 1122. The limiting structure 1122 extends along the first direction to form a wire passage between it and the outer wall of the heating tube 1, so that the heating element 2 can pass through between the limiting structure 1122 and the outer wall of the heating tube 1 and abut against the support structure 1121, thereby limiting the heating element 2 and preventing the heating element 2 from separating from the support structure 1121. It also facilitates assembly in the manufacturing process.
[0057] Furthermore, such as Figure 10 In the example, the limiting structure 1122 facing the heating tube 1 can be provided with a corresponding groove structure 1123 so that the passing heating element 2 can be engaged in the groove structure 1123; the form of the groove structure 1123 can be set according to the shape of the heating element 2, for example, it can be set as Figure 10 The arc-shaped groove shown is adapted to fit the cylindrical cross-section of the heating element 2; when the heating element 2 adopts other shapes, the groove structure 1123 can also be set to the corresponding structural form.
[0058] In further embodiments of this application, such as Figures 1 to 3 In the example, the heating element 2 specifically adopts a filamentous structure, that is, it uses a heating wire as the heating element 2. The heating wire is usually relatively small in diameter, with low weight and resistance, resulting in high heating efficiency. Moreover, the heating wire has a certain degree of flexibility, making it easy to shape and wind, and a small support structure 1121 can be used for support and fixation. Of course, in practical applications, strip-shaped or sheet-shaped heating elements 2 can also be used, or different forms of heating elements 2 can be used simultaneously, depending on the specific application requirements.
[0059] Furthermore, in a specific example, such as Figures 1 to 3 As shown, the surface of the heating element 2 is provided with an infrared radiation coating, which can effectively promote the infrared radiation effect of the heating element 2, increase the amount of infrared radiation during heating, and help to further improve the heating efficiency of the aerosol generating rod 500.
[0060] Furthermore, in a specific example, such as Figures 1 to 3 As shown, the surface of the heating element 2 is provided with an anti-oxidation coating, which can effectively improve the anti-oxidation ability of the heating element 2, prevent the heating element 2 from being affected by oxidation, and help to enhance the heating effect and extend the service life.
[0061] Furthermore, in a specific example, such as Figures 1 to 3As shown, the heating element 1 adopts a quartz tube structure, which is a type of ceramic tube, allowing infrared rays generated by the heating element 2 to pass through and heat the aerosol generating rod 500 within the cavity 11. The quartz tube, compared to a metal tube, has an insulating effect and a relatively low thermal conductivity, providing insulation and ensuring better uniform heating of the aerosol generating rod 500, as infrared radiation from the heating element 2 is the primary heating method. Furthermore, the quartz tube does not release metal ions during heating, thus preventing any impact on the taste of the aerosol mixture.
[0062] An embodiment of the second aspect of this application provides an atomizing device 400, such as... Figure 11 , Figure 12 , Figure 13 As shown, the atomizing device 400 includes a housing 410, a heating component 100 as described in any of the embodiments of the first aspect, and a power supply component 420. The housing 410 serves as the mounting carrier for the atomizing device 400, and has a specific assembly port 4111 at one end in the first direction. Both the heating component 100 and the power supply component 420 are disposed in the housing 410, and the insertion port 111 of the heating component 100 is correspondingly provided with the assembly port 4111 of the housing 410 for the aerosol generating rod 500 to be inserted. The power supply component 420 is electrically connected to the heating element 2 of the heating component 100 to supply power to the heating element 2, enabling the heating element 2 to generate heat when energized. When the aerosol generating rod 500 passes through the assembly port 4111 and the insertion port 111 along the first direction and enters the receiving cavity 11 formed by the heating tube 1, the heating element 2 surrounds the circumferential outer side of the heating tube 1. The heating element 2 heats up when energized and can generate infrared radiation. The infrared rays can penetrate the heating tube 1 and enter the receiving cavity 11, thereby forming infrared radiation heating of the aerosol generating rod 500. In addition, the airflow flowing over the surface of the aerosol generating rod 500 is heated to form a hot airflow, which can also produce a heating effect on the aerosol generating rod 500.
[0063] The following describes a specific example of the atomizing device 400 of this application with reference to the accompanying drawings.
[0064] like Figures 1 to 13 As shown, the atomizing device 400 is specifically a heat-not-burning device. In the atomizing device 400, the first direction of the housing 410 is the height direction, and an interface structure 411 is located at the top of the housing 410. The interface structure 411 protrudes upward, and the insertion port 111 is located in the interface structure 411. The interior of the housing 410 is divided into different chambers, such as... Figure 13In the example shown, the power supply assembly 420 is located in the right chamber. The left chamber has a heat insulation sleeve 413 and a support structure 414. The support structure 414 is fixedly connected to the bottom of the housing 410. The heat insulation sleeve 413 is sleeved on the top of the support structure 414 and connected to the housing 410. The heat insulation sleeve 413 is correspondingly provided with the interface structure 411 and together with the support structure 414, they form an installation cavity 412. The support structure 414 includes a support body 4143 and a heating base 4141; the heating base 4141 is located on top of the support body 4143, and the heating base 4141 has a vent hole 4142 communicating with the mounting cavity 412; the support body 4143 has an air intake channel 4144 communicating with the vent hole 4142, and the bottom of the housing 410 has an air inlet 415 so that external air can pass through the air inlet 415, the air intake channel 4144 and the vent hole 4142 into the mounting cavity 412.
[0065] The heating component 100 is disposed in the mounting cavity 412 along the first direction. The heating tube 1 adopts a quartz tube structure. Both ends of the heating tube 1 are open, and the insertion port 111 of the heating tube 1 faces the assembly port 4111. The end of the heating tube 1 away from the insertion port 111 is connected to the heating base 4141 so that the vent 4142 and the air inlet channel 4144 are connected to the inside of the heating tube 1. External gas can pass through the air inlet 415, the air inlet channel 4144 and the vent 4142 into the receiving cavity 11 of the heating tube 1, and be sucked into the aerosol generating rod 500 to mix with the aerosol generated by the atomizing matrix, and then flow to the suction end of the aerosol generating rod 500.
[0066] like Figures 1 to 3 as well as Figure 13 As shown, the heating element 2 of the heating assembly 100 is specifically in the form of a heating wire, which includes two lead segments 21, multiple flat segments 22, and multiple spiral segments 23. The two lead segments 21 are located at both ends of the heating wire, and after being led out, they are electrically connected to the power supply assembly 420. The flat segments 22 and spiral segments 23 are alternately arranged between the two lead segments 21. Each flat segment 22 extends circumferentially along the heating tube 1 and abuts against multiple support structures 1121 of a corresponding support layer 112. The spiral segments 23 are spirally arranged along a first direction and connected to two adjacent flat segments 22. The heating wire is a one-piece molded structure, and the lead segments 21, flat segments 22, and spiral segments 23 are all at different positions within a single heating wire. The receiving cavity 11 is coaxially arranged with the assembly port 4111, and on the projection plane perpendicular to the first direction, the area of the receiving cavity 11 is slightly larger than the area of the assembly port 4111, so as to ensure that the aerosol generating rod 500 can be accurately inserted into the receiving cavity 11 of the heating tube 1 after passing through the assembly port 4111 along the first direction.
[0067] The power supply assembly 420 includes a battery and an electronic control board that are electrically connected; the electronic control board is provided with a control circuit and is electrically connected to the pin segment 21 of the heating wire; the power supply state of the battery to the heating wire is controlled by the electronic control board.
[0068] In this embodiment, the atomizing device 400 utilizes a heating element 2 wrapped around the outside of a quartz heating tube 1, and is supported by a support structure 1121 on the outer wall of the heating tube 1. The heating element 2 can generate heat when energized and radiate infrared rays into the interior of the heating tube 1, making the aerosol generating rod 500 contained in the heating tube 1 more evenly heated. This helps prevent localized severe baking or over-baking, improves the user experience, and has a relatively simple structure. It does not require printing thick-film resistors or setting up a vacuum chamber, which avoids deformation, collapse, displacement, etc. caused by installing the heating element 2 in a vacuum chamber. This effectively reduces the difficulty of processing and manufacturing, and helps reduce manufacturing costs. Moreover, the heating tube 1 does not release metal ions during the heating process, which can avoid affecting the taste of the aerosol mixture.
[0069] In addition, the atomizing device 400 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.
[0070] 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.
