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, heating methods in heated non-combustible atomizing devices mainly include circumferential heating and central heating. In devices using circumferential heating, thick-film resistors are typically printed on the sidewalls of a metal 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 printing process of the thick-film resistors is relatively complex, the yield rate is difficult to improve, and the processing cost is high. Moreover, the heat conduction from the tube to the aerosol generating rod is prone to uneven heating, easily causing localized severe baking or over-baking. Furthermore, the metal tube will release some metal ions at high temperatures, affecting the atomization effect and the inhalation taste, which is detrimental to improving the user experience.

[0032] 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.

[0033] 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).

[0034] 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.

[0035] The heating assembly provided in this application provides a heating element between the first and second support walls of the support member. The heating element is arranged to form a receiving space for accommodating the aerosol generating rod. After the aerosol generating rod passes through the first opening and enters the receiving space, the heating element can be energized and heated. It directly heats the aerosol generating rod by radiating infrared rays, and at the same time, it heats the air flowing over the surface of the aerosol generating rod to form a hot airflow, thereby achieving a composite heating method to improve the uniformity of heating the aerosol generating rod.

[0036] The following describes some embodiments of the heating components and atomizing devices provided in this application with reference to the accompanying drawings.

[0037] 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 support member 1 and a heating element 2. The support member 1 is arranged along a first direction and has a first support wall 11 and a second support wall 12 arranged opposite to each other in the first direction. The heating element 2 is disposed between the first support wall 11 and the second support wall 12. A first opening 111 is provided on the first support wall 11, and the first opening 111 is adapted to the aerosol generating rod 500 so that the aerosol generating rod 500 can pass through. The heating element 2 is arranged circumferentially around the first opening 111, and the heating element 2 extends along the first direction so that the inner side of the heating element 2 forms a receiving space 20 that can accommodate the aerosol generating rod 500. The receiving space 20 is correspondingly arranged with the first opening 111 so that the aerosol can pass through the first opening 111 and enter the receiving space 20. The heating element 2 surrounds the periphery of the aerosol generating rod 500 so as to heat different areas of the aerosol generating rod 500 in the circumferential direction. The second support wall 12 has multiple ventilation holes 121, and the ventilation holes 121 are correspondingly arranged with the receiving space 20. After the aerosol generating rod 500 is inserted into the receiving space 20, its end face can abut against the second support wall 12. When the aerosol generating rod 500 is suctioned, air can pass through the ventilation holes 121 and enter the interior of the aerosol generating rod 500.

[0038] It is understandable that existing atomizing devices typically use a metal tube as the base, with thick-film resistors printed on the sidewalls of the metal tube as heating elements. Heat is then conducted to the aerosol generating rod inside the metal tube. However, the process of printing thick-film resistors is quite complex, and uneven heat distribution inevitably occurs on the metal tube, affecting the uniformity of heating the aerosol generating rod. Furthermore, the metal tube releases some metal ions at high temperatures, which affects the atomization effect of the aerosol generating rod and the taste of the mixed airflow.

[0039] The heating component in this embodiment, through structural improvements and optimizations, utilizes a heating element to form a receiving space for the aerosol generating rod. When the aerosol generating rod is inserted into the receiving space, the heating element can directly heat the aerosol generating rod with infrared radiation, and can also heat the surrounding airflow to form a hot airflow that heats the aerosol generating rod. This eliminates the need for a heat-conducting structure, effectively improving the heating uniformity of the aerosol generating rod, preventing localized severe baking or scorching, and preventing the release of metal ions from existing metal heat pipes after heating, thus improving the user experience. Furthermore, it simplifies the overall structure and reduces processing difficulty and costs.

[0040] It should be noted that in practical applications, the support components can be configured with corresponding structural forms according to the usage requirements. For example, the support components can be open or closed structures in the circumferential direction; the specific shape and size of the first and second support walls can also be designed according to the specific structural dimensions of the main housing of the atomizing device being assembled.

[0041] In further embodiments of this application, such as Figure 1 and Figure 2 As shown, in the heating assembly 100, the heating element 2 includes at least one heating wire 21. The heating wire 21 is wound circumferentially around the first opening 111. At least a portion of the heating wire 21 extends along a first direction from the first support wall 11 toward the second support wall 12, forming a hollow structure with an inner receiving space 20. When the heating wire 21 is energized, it can radiate infrared rays to the surroundings to conduct heat to the aerosol generating rod 500 within the receiving space 20. Simultaneously, since the heating element 2 formed by the heating wire 21 is a hollow structure, the surrounding airflow can be heated to form a hot airflow. When the hot airflow flows over the surface of the aerosol generating rod 500, it can also conduct heat to the aerosol generating rod 500, forming a hot airflow heating effect. By using the heating element formed by the winding of the heating wire 21, the structure is simple, and the heat conduction is more uniform. Heat can be quickly conducted to any area within the receiving space 20 to prevent local areas from overheating and causing overheating.

[0042] It should be noted that, in practical applications, the number of heating wires is not limited to... Figure 1 The diagram shows one heating wire, but multiple heating wires can be installed as needed; in addition, the specific winding method of the heating wires can also be selected according to the usage requirements.

[0043] Furthermore, in a specific implementation, such as Figure 1 and Figure 2 In the example, at least a portion of the heating wire 21 is arranged in a spiral manner in the first direction to form a spring-like structure, enabling it to cover any area in the circumferential direction where the aerosol generating rod 500 is inserted into the receiving space 20. Preferably, the pitch of the heating wire 21 is equal in the first direction, so that the spacing of each turn of the heating wire 21 around the aerosol generating rod 500 in the first direction is equal, resulting in a more uniform area covered by the emitted infrared rays, which is beneficial for further improving heating uniformity. Both ends of the heating wire 21 extend outward from the receiving space 20 to form the pin structure 211 of the heating element 2; when the heating assembly 100 is applied to the atomizing device, it is electrically connected to the power supply assembly of the atomizing device through the pin structure 211, so that the power supply assembly supplies power to the heating wire 21, causing the heating wire 21 to heat up.

[0044] Furthermore, in a specific implementation, such as Figure 3In the example, the heating element 2 includes a plurality of heating wires 21 and at least two pin structures 211. The plurality of heating wires 21 are arranged crosswise and connected to form a heating mesh 22. The heating mesh 22 is wound around the circumference of the first opening 111 to form a cylindrical structure, and the internal space enclosed by the heating mesh 22 forms a receiving space 20. The heating mesh 22 extends a certain length in a first direction to cover the portion of the aerosol generating rod 500 inserted into the receiving space 20. Correspondingly, at least two pin structures 211 are connected to the outer wall of the heating mesh 22, and the ends of the pin structures 211 extend out for electrical connection with the power supply component.

[0045] In practical applications, the number and location of pins can be configured according to usage requirements. For example... Figure 3 In the example, two pin structures are connected to opposite sides of the heating grid, and both extend along the first direction. When the two pin structures are energized, the heating grid can heat up completely.

[0046] Of course, the pin structure can also be configured with more than two other numbers, for example... Figure 4 In the example, three pin structures can be provided on the outer wall of the heating mesh along the first direction, with two pin structures connected to the two ends of the heating mesh in the first direction and the other pin structure connected to the middle area of ​​the heating mesh; all three pin structures are electrically connected to the power supply component so that two adjacent pin structures can form a parallel state, and the power supply component can be controlled to supply power to any two of the pin structures as needed to form segmented heating or overall heating.

[0047] For example, in Figure 4 In the example, the three pin structures 211 divide the heating grid 22 into a parallel upper heating section and a lower heating section. When the upper pin structure 211 and the middle pin structure 211 are energized simultaneously, the upper heating section heats up; when the middle pin structure 211 and the lower pin structure 211 are energized simultaneously, the lower heating section heats up; when the upper pin structure 211 and the lower pin structure 211 are energized simultaneously, the entire heating grid 22 heats up. A preset control program can be set for the power supply component according to heating requirements, so that the energizing state of the heating element 2 is controlled according to the preset control program during use, thereby accelerating the atomizing matrix inside the aerosol generating rod 500 to reach the atomization temperature and generate aerosol, which is beneficial to improving heating efficiency.

[0048] Furthermore, in one specific embodiment, such as Figures 1 to 4 In the example, in heating element 2, the surface of heating wire 21 is provided with an infrared radiation coating, which can effectively promote the infrared radiation effect of heating wire 21, increase the amount of infrared radiation during heating, and help to further improve the heating efficiency of aerosol generating rod 500.

[0049] Furthermore, in one specific embodiment, such as Figures 1 to 4 In the example, in heating element 2, the surface of heating wire 21 is provided with an anti-oxidation coating, which can effectively improve the anti-oxidation ability of heating wire 21, prevent heating wire 21 from oxidizing and affecting heating, and help enhance heating effect and extend service life.

[0050] In further embodiments of this application, such as Figure 1 and Figure 5 As shown, the first opening 111 is specifically a circular opening adapted to the aerosol generating rod 500, and the accommodating cavity formed by the heating element 2 is specifically a cylindrical cavity adapted to fit the first opening 111 and the aerosol generating rod 500. In the radial direction, the diameter of the accommodating space 20 is larger than the diameter of the first opening 111, so that on the projection plane perpendicular to the first direction, the first opening 111 is entirely located within the accommodating space 20, so that a radial gap L1 is formed between the inner edge of the accommodating space 20 and the inner edge of the first opening 111. When the aerosol generating rod 500 passes through the first opening 111 along the first direction and extends into the accommodating space 20, a certain gap is maintained between the outer wall of the aerosol generating rod 500 and the inner edge of the accommodating space 20 to prevent the aerosol generating rod 500 from contacting the heating element 2.

[0051] It is understood that aerosol generating rods are typically cylindrical, and the diameter of the insertion port is the same as or slightly larger than the diameter of the aerosol generating rod, so that the aerosol generating rod can pass smoothly through the insertion port. In one specific example, such as... Figure 5 As shown, the radial gap L1 between the accommodating space 20 and the first opening 111 is in the range of 0.5mm to 1mm, which can satisfy the requirement that the heating element 2 and the aerosol generating rod 500 inserted into the accommodating space 20 form a non-contact state, while also allowing the heating element 2 to be as close as possible to the surface of the aerosol generating rod 500 to enhance the heating effect.

[0052] Specifically, such as Figure 5 In the example, the first opening 111 and the receiving space 20 are coaxially arranged, that is, the circle formed by the edge of the first opening 111 and the circle formed by the receiving space 20 are concentric circles. When the aerosol generating rod 500 is inserted into the receiving space 20, the radial gap between it and the heating element 2 is the same at any position in the circumferential direction, that is, the heat transfer distance is the same, which can further improve the heating uniformity of different areas on the aerosol generating rod 500.

[0053] In further embodiments of this application, such as Figure 6In the example, on the first support wall 11 of the support member 1, a first fixing structure 112 is provided on the side facing the second support wall 12. Specifically, the first fixing structure 112 is located at the periphery of the first opening 111. The first fixing structure 112 extends a distance along a first direction and extends into the receiving space 20 formed by the heating element 2, abutting against the inner side of the heating element 2 to fix and position the heating element 2. Multiple first fixing structures 112 can be provided and spaced apart circumferentially, such as... Figure 6 The state shown is as described above; of course, a first fixing structure 112 can also be set to extend continuously along the circumference, forming a structure similar to a mounting groove, so as to simultaneously abut against the heating element 2 at different positions in the circumference, thereby fixing and positioning the heating element 2. It should be noted that in practical applications, the first fixing structure 112 can also be set on the outside of the heating element 2, so as to abut against the outer wall of the heating element 2, which can also fix and position the heating element 2.

[0054] Furthermore, such as Figure 6 In the example shown, on the support member 1, the second support wall 12 has a second fixing structure 122 on the side facing the first support wall 11. The second fixing structure 122 is correspondingly arranged around the periphery of the first opening 111, and extends a certain distance along the first direction, extending into the receiving space 20 formed by the heating element 2 to abut against the inner side of the heating element 2, thereby fixing and positioning the heating element 2. Multiple second fixing structures 122 can be provided and spaced apart circumferentially, such as... Figure 6 The state shown is as described; of course, a second fixing structure 122 can also be set to extend continuously in the circumferential direction, forming a structure similar to a mounting groove, so as to simultaneously abut against the heating element 2 at different positions in the circumferential direction, so as to fix and position the heating element 2. In practical applications, the first fixing structure 112 can also be set on the outside of the heating element 2, so as to abut against the outer wall of the heating element 2, which can also fix and position the heating element 2.

[0055] It should be noted that in practical applications, the first fixing structure 112 and the second fixing structure 122 can be set simultaneously according to the needs of use, or the first fixing structure 112 or the second fixing structure 122 can be set separately.

[0056] In further embodiments of this application, such as Figure 2 and Figure 7In the example shown, multiple vents 121 are arranged in an array on the second support wall 12 so that when the aerosol generating rod 500 is inserted into the receiving space 20, the gas on the other side of the second support wall 12 can pass through the multiple vents 121 and enter the interior of the aerosol generating rod 500 more evenly, so that the airflow can mix more fully with the aerosol inside the aerosol generating rod 500. Specifically, the vents 121 can be arranged in a matrix, a ring array, a regular polygon array, or other array forms, and the number and diameter of the vents 121 can be set according to the actual air intake requirements.

[0057] In further embodiments of this application, such as Figure 8 As shown, in the support member 1, the second support wall 12 has a third fixing structure 123 on the side facing the first support wall 11. The third fixing structure 123 is specifically located within the receiving space 20 and extends a distance along the first direction. When the aerosol generating rod 500 is inserted into the receiving space 20, the third fixing structure 123 can penetrate into the aerosol generating rod 500 to fix it in place. Specifically, the third fixing structure 123 can be designed as follows: Figure 8 The columnar structure with spikes shown is designed to facilitate insertion into the aerosol generating rod 500; the third fixing structure 123 is offset from the vent 121 to prevent obstruction of the vent 121.

[0058] It should be noted that the third fixing structure 123 can also be a needle-like structure or a sheet-like structure; furthermore, the number of the third fixing structures 123 is not limited to... Figure 8 The diagram shows one, but multiple third fixing structures 123 can also be set simultaneously.

[0059] In further embodiments of this application, such as Figures 1 to 4 As shown, the support member 1 also includes a side support wall 13, which is arranged along the first direction and located on one side of the heating element 2. One end of the side support wall 13 in the first direction is connected to the first support wall 11, and the other end of the side support wall 13 is connected to the second support wall 12, so as to connect the first support wall 11 and the second support wall 12 into one unit through the side support wall 13, so as to support and fix the first support wall 11 and the second support wall 12, and keep the relative position between the first support wall 11 and the second support wall 12 fixed. By setting the side support wall 13 on the side of the heating element 2, the support member 1 forms an open structure as a whole, that is, a hollow structure in a certain area in the circumferential direction, which further simplifies the structure, facilitates the assembly of the heating element 2, and also prevents too much support structure from contacting the heating element 2 and affecting the heating effect.

[0060] In further embodiments of this application, such as Figure 8As shown, on the side of the first support wall 11 facing away from the second support wall 12, a guide structure 113 is also provided at the edge of the first opening 111. The guide structure 113 is arranged circumferentially along the first opening 111 and extends a certain distance in the first direction. When the aerosol generating rod 500 passes through the first opening 111, the guide structure 113 guides the aerosol generating rod 500, making it easier for the aerosol generating rod 500 to align with the first opening 111 and preventing collision between the aerosol generating rod 500 and the edge of the first opening 111. Specifically, the guide structure 113 can be a cylindrical structure or a plurality of arc-shaped plate structures spaced apart circumferentially along the first opening 111.

[0061] An embodiment of the second aspect of this application provides an atomizing device 400, such as... Figure 9 , Figure 10 , Figure 11 As shown, the atomizing device 400 includes a main housing 410, a heating component 100 as described in any of the embodiments of the first aspect, and a power supply component 420. The main housing 410 serves as the mounting carrier for the atomizing device 400, and has a second opening 411 at one end in the first direction. Both the heating component 100 and the power supply component 420 are disposed in the main housing 410, and the first opening 111 of the heating component 100 corresponds to the second opening 411 of the main 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 first opening 111 and the second opening 411 along the first direction and enters the receiving space 20 formed by the heating element 2, the heating element 2 surrounds the circumferential outer side of the aerosol generating rod 500. When the heating element 2 is energized, it can generate infrared radiation and heat the air flowing through the surface of the aerosol generating rod 500 to form a hot airflow, thereby forming infrared radiation heating and hot airflow heating of the aerosol generating rod 500.

[0062] The following describes a specific example of the atomizing device 400 of this application with reference to the accompanying drawings.

[0063] like Figures 1 to 11 As shown, the atomizing device 400 is specifically a heat-not-burning device. In the atomizing device 400, the first direction of the main housing 410 is the height direction. An interface structure 415 protrudes upwards from the top of the main housing 410, and a second opening 411 is located on the interface structure 415. The interior of the main housing 410 is divided into different chambers, such as... Figure 11In the example shown, the power supply component 420 is located in the right chamber.

[0065] like Figure 1 , Figure 2 as well as Figure 11 As shown, the heating element 2 of the heating assembly 100 is specifically in the form of a heating wire 21. The heating wire 21 is spirally arranged along a first direction, forming a cylindrical receiving space 20 on its inner side. The receiving space 20 is coaxially arranged with the first opening 111, and there is a radial gap between the inner edge of the receiving space 20 and the inner edge of the insertion port. When the aerosol generating rod 500 is inserted into the receiving space 20, one end of the insertion abuts against the second support wall 12, and the side wall of the aerosol generating rod 500 abuts against the inner edge of the first opening 111.

[0066] 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 the two ends of the heating wire 21 form a pin structure 211 and are electrically connected to the electronic control board; the power supply state of the battery to the heating wire 21 is controlled by the electronic control board.

[0067] In this embodiment, the atomizing device 400 uses a heating component 100 formed by spirally winding a heating wire 21 to form a heating element 2, and has a receiving space 20 for accommodating an aerosol generating rod 500. When the aerosol generating rod 500 is inserted into the receiving space 20, there is a radial gap between it and the heating wire 21. The heating element 2 can not only directly heat the aerosol generating rod 500 with infrared radiation, but also heat the surrounding airflow to form a hot airflow that heats the aerosol generating rod 500. There is no need to set up a heat-conducting structure, which improves the heating uniformity of the aerosol generating rod 500 and can effectively prevent the phenomenon of severe local baking or burning. It can also prevent the phenomenon of metal ion release after existing metal heat-conducting tubes are heated, which is beneficial to improving the user experience. In addition, it simplifies the overall structure, eliminates the need for printing resistors, and reduces the processing difficulty and processing cost.

[0068] 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.

[0069] 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.
