Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular provides a heating element, an atomizer, and an electronic atomization device. Background Technology
[0002] The mesh heating element (i.e., Mesh heating mesh) of an atomizer is a heating element made of metal plate or metal tube through chemical etching, stamping, laser / mechanical engraving and other methods to form honeycomb, rhombus or rectangular patterns. The resistance of the heating element and the degree of heat concentration are adjusted by controlling the size of the pattern.
[0003] When existing mesh heating elements are heated, the heat is mainly concentrated on the curves of the upper and lower sets of mesh holes. However, this has the following drawbacks: insufficient heat dissipation area leads to low heat dissipation efficiency, local overheating leads to material deterioration, resulting in a shorter lifespan of the heating element, the heating element is prone to deformation due to expansion at high temperatures (especially iron-chromium-aluminum alloys), and the liquid guiding path is deviated after the mesh holes are stretched and deformed, resulting in uneven atomization or leakage. Utility Model Content
[0004] The purpose of this application is to provide a heating element, an atomizer, and an electronic atomizing device, in order to solve the problems of low heat dissipation efficiency, easy local overheating leading to material deterioration, and affecting the lifespan of the heating element in existing atomizers.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, embodiments of this application provide a heating element, including a first electrode, a second electrode, a heating part, and a heat sink; the heating part includes at least two heating lines arranged at intervals; the two ends of each heating line are respectively connected to the first electrode and the second electrode; a plurality of hollow parts are formed between adjacent two heating lines; the heat sink is disposed on the heating lines, and the heat sink extends from the heating lines to the hollow parts.
[0007] The beneficial effects of the atomizer of this application are as follows: by placing the heat sink on the heating circuit and extending it into the hollow part, the high temperature heat generated in the heating circuit can be quickly conducted to the heat sink. Moreover, the heat sink is exposed in the hollow part. When the airflow passes through the heating element, the heat at the heat sink can be quickly conducted to the airflow through heat exchange, so that the heating circuit has a faster heat dissipation speed, avoids excessive local temperature, and is not prone to overheating, thereby extending its service life.
[0008] In some embodiments, the heating circuit includes a plurality of heating elements connected in sequence, and a heat sink is provided at the intersection of two adjacent heating elements.
[0009] By adopting the above technical solution, the contact resistance at the intersection of two adjacent heating elements usually leads to an increase in the resistance value of that part, which means that the heat generated when energized is higher. Therefore, the heat sink is placed at the intersection of two adjacent heating elements to effectively dissipate heat from the concentrated area and avoid excessive local temperature.
[0010] In some embodiments, two adjacent heating lines are spaced apart between two heat sinks within the same hollow portion.
[0011] By adopting the above technical solution, the heat sink is only used to disperse the heat on the heating circuit. Therefore, there is a gap between two heat sinks that are opposite each other in the same hollow part, and the current will not form a circuit through the two.
[0012] In some embodiments, the heating element further includes multiple branches disposed on the heating line and extending in a direction away from the hollowed-out portion.
[0013] By adopting the above technical solution, the heat on the heating circuit can be further conducted to the branch circuit, which can increase the heating area of the heating part; furthermore, the branch circuit can also disperse the heat of the heating circuit, avoid excessive local temperature, and extend the service life of the heating element.
[0014] In some embodiments, the branch intersects with the heat sink.
[0015] By adopting the above technical solution, the heat at the heating point of the heating circuit can be conducted to the branches and heat sinks on both sides, dispersing the central heat evenly to the surrounding areas and effectively improving the heat dissipation effect.
[0016] In some embodiments, the heating element further includes a plurality of connecting units connected between two adjacent heating lines, and the hollow portion is formed by the connecting units enclosing the two adjacent heating lines.
[0017] By adopting the above technical solution, multiple connecting units are connected between two heating lines, so that the heating part forms multiple spaced hollow parts, and each heat sink extends out and is exposed in the hollow part, which is conducive to heat exchange with airflow.
[0018] In some embodiments, the heating element is symmetrical about the connecting element.
[0019] By adopting the above technical solution, the heating element forms multiple grid structures with spaced intervals and equal areas, resulting in uniform heat distribution and higher heating efficiency.
[0020] In some embodiments, the number of heating circuits is two.
[0021] Secondly, this application also provides an atomizer, including a main body having a liquid storage chamber and an atomizing core disposed within the main body; the atomizing core includes a liquid inlet substrate and the heating element; the liquid inlet substrate has a through-hole, and the heating element is disposed within the through-hole.
[0022] The atomizer of this application uses the aforementioned heating element in its atomizing core. The heating element provides uniform heating and has good heat dissipation capabilities, effectively preventing excessively high local temperatures, reducing coking rate during atomization, thereby reducing energy consumption, extending the lifespan of the atomizing core, and improving device stability.
[0023] Thirdly, this application also provides an electronic atomizing device, including a power module and the atomizer, wherein the power module is used to supply power to the heating element of the atomizer. Attached Figure Description

[0046] In existing atomizers, the heat from the mesh heating element is mainly concentrated on the curves of the upper and lower sets of mesh holes. However, this has the following drawbacks: insufficient heat dissipation area leads to low heat dissipation efficiency, local overheating leads to material deterioration, resulting in a shorter lifespan of the heating element, and the heating element is prone to deformation due to expansion at high temperatures (especially iron-chromium-aluminum alloys). After the mesh holes are stretched and deformed, the liquid guiding path is deviated, resulting in uneven atomization or leakage.
[0047] Based on this, in order to solve the above problems, this application designs a heating element, an atomizer, and an electronic atomizing device. By placing a heat sink on the heating circuit and extending it into the hollow part, the high temperature heat generated in the heating circuit can be quickly conducted to the heat sink. The heat sink is exposed in the hollow part. When the airflow passes through the heating element, the heat at the heat sink can be quickly conducted to the airflow through heat exchange, so that the heating circuit has a faster heat dissipation speed, avoids excessive local temperature, and is not prone to overheating, thereby extending its service life.
[0048] refer to Figure 1 , Figure 2 and Figure 3 This application provides a heating element 100, including a first electrode 1, a second electrode 2, a heating part 3, and a heat sink 4; the heating part 3 includes at least two heating lines 5 arranged at intervals, and the two ends of each heating line 5 are respectively connected to the first electrode 1 and the second electrode 2; a plurality of hollow parts 6 are formed between adjacent two heating lines 5; the heat sink 4 is disposed on the heating lines 5, and the heat sink 4 extends from the heating lines 5 to the hollow parts 6.
[0049] Understandably, the heating element 100 of this application is specifically applied in an atomizing device, wherein the heating part 3 is used to generate heat by electricity, and heats and atomizes the aerosol matrix in the atomizing device; by simultaneously energizing the first electrode 1 and the second electrode 2, current flows through each heating circuit 5, and due to the resistance of the heating circuit 5, electrical energy is converted into heat energy, causing each heating circuit 5 to generate heat. The number of heating circuits 5 is two or more, and each heating circuit 5 is spaced apart and arranged in parallel along the length direction of the first electrode 1 / the length direction of the second electrode 2, thereby increasing the heating area of the heating part 3.
[0050] refer to Figure 2 and Figure 3 The heating element 3 has a mesh structure, and multiple hollow parts 6 are formed between two adjacent heating lines 5. The hollow parts 6 are mesh structures with shapes such as circles, ellipses, rhombuses, and polygons.
[0051] For example, the perforated portion 6 is a hexagonal mesh; current flows in the mesh structure, generating heat, and the heat is evenly distributed through the mesh structure to achieve better heating efficiency.
[0052] The heating element 100 of this application, by placing the heat sink 4 on the heating circuit 5 and extending it to the hollow portion 6, allows the high-temperature heat generated in the heating circuit 5 to be quickly conducted to the heat sink 4. The heat sink 4 is exposed in the hollow portion 6. When the airflow passes through the heating element 100, the heat at the heat sink 4 can be quickly conducted to the airflow through heat exchange, so that the heating circuit 5 has a faster heat dissipation speed, avoids excessive local temperature, and is not prone to overheating, thereby extending its service life.
[0053] Understandably, multiple heat sinks 4 can be installed on each heating circuit 5. The heat sinks 4 are arranged at intervals along the extension direction of the heating circuit 5 to form a multi-level heat dissipation channel, increase the heat dissipation area, and make the heat of the heating part 3 more evenly distributed and the heating stability better.
[0054] The heat sink 4 can be in the form of a straight line, a curve, or other shapes, as long as the heat on the heating circuit 5 can be conducted to the heat sink 4.
[0055] refer to Figure 2 and Figure 3 In some embodiments, the heating circuit 5 includes a plurality of heating elements 51 connected in sequence, and a heat sink 4 is provided at the intersection of two adjacent heating elements 51.
[0056] Understandably, the contact resistance at the intersection of two adjacent heat-generating units 51 usually leads to an increase in the resistance value of that part, which means that the heat generated when energized is higher. Therefore, the heat sink 4 is placed at the intersection of two adjacent heat-generating units 51 to effectively dissipate heat from the concentrated area and avoid excessive local temperature.
[0057] For example, the heating line 5 can be a zigzag line or a wavy line, or a combination of zigzag lines and wavy lines.
[0058] In some embodiments, such as Figure 3 As shown, the heating circuit 5 is a tortuous line, and each heating element 51 is V-shaped. The heating circuit 5 is composed of multiple heating elements 51 arranged along a circular path. A heat sink 4 is provided at the intersection of any two adjacent heating elements 51.
[0059] In some other embodiments, the heating line 5 is a wavy line, and the heating line 5 is formed by multiple arc-shaped heating elements 51 arranged along a ring path, with a heat sink 4 provided at the intersection of any two adjacent heating elements 51.
[0060] refer to Figure 2 and Figure 3 In some embodiments, adjacent two heating lines 5 are spaced apart between two heat sinks 4 within the same hollow portion 6.
[0061] Understandably, the purpose of placing the heat sink 4 on the heating circuit 5 is to disperse the heat on the heating circuit 5 and avoid excessive local heat. Therefore, there is a gap between the two heat sinks 4 opposite each other in the same hollow part 6, and the current will not form a circuit through the two heat sinks 4. Each heat sink 4 effectively dissipates heat from its corresponding heating circuit 5 independently.
[0062] In some embodiments, preferably, the number of heating circuits 5 is 2.
[0063] refer to Figures 1 to 3 In some embodiments, the heating element 3 also includes multiple branch lines 7 disposed on the heating line 5 and extending in a direction away from the hollowed-out part 6.
[0064] Specifically, branch circuit 7 is located on the heating element 3 and extends outward from the heating element 3. The heat from the heating circuit 5 can be further conducted to branch circuit 7, which can increase the heating area of the heating element 3. Furthermore, branch circuit 7 can also disperse the heat from the heating circuit 5, avoid excessive local temperature, and extend the service life of the heating element 100.
[0065] refer to Figure 3 In some embodiments, branch 7 intersects with heat sink 4.
[0066] Specifically, the heat sink 4 is located at the intersection of two adjacent heating elements 51 and extends towards the center of the hollow portion 6; the branch 7 is located at the intersection of two adjacent heating elements 51 and extends away from the hollow portion 6. Subsequently, the heat from the heating line 5 at the intersection of the two heating elements 51 can be conducted to the branch 7 and the heat sink 4 on both sides, dispersing the central heat evenly to the surrounding area, effectively improving the heat dissipation effect and preventing excessively high local temperatures on the heating line 5. The branch 7 and the heat sink 4 together form the heat dissipation path on the heating line 5.
[0067] In some embodiments, the branch 7 is elongated and the heat sink 4 is elongated.
[0068] Understandably, branch 7 and heat sink 4 are located on the same straight line, and the heat on the heating line 5 can be transferred to both sides along the length of the straight line, resulting in higher heat transfer efficiency and better dispersion of central heat.
[0069] refer to Figures 1 to 3 In some embodiments, the heating element 3 further includes a plurality of connecting units 8 connected between two adjacent heating lines 5; the two adjacent heating lines 5 are enclosed by the connecting units 8 to form a hollow part 6.
[0070] Specifically, multiple connecting units 8 are arranged at intervals, and the two ends of the connecting units 8 are respectively connected to two adjacent heating lines 5. The heating part 3 forms multiple spaced hollow parts 6, and each heat sink 4 extends out and is exposed in each hollow part 6, which facilitates heat exchange with airflow and improves heat dissipation performance.
[0071] refer to Figure 2 and Figure 3 In some embodiments, the heating element 51 is symmetrical about the connecting element 8.
[0072] For example, the connecting unit 8 is elongated and forms the axis of symmetry of the heating unit 51.
[0073] refer to Figure 3 In some embodiments, a single heating element 51 is V-shaped, and the two ends of the connecting element 51 are respectively connected to the intersection of two opposite heating elements 51 that are not on the same heating line 5, thereby forming multiple spaced and equally sized hollow parts 6 in the heating part 3. The heating part 3 has a regular structure and the heat is evenly distributed.
[0074] Specifically, two opposing heating elements 51 on two adjacent heating lines 5 are connected in series by a connecting element 8, which means that good heat conduction is formed between the two heating lines 5, and the heat of the heating element 100 is evenly distributed, achieving higher heating efficiency.
[0075] Secondly, refer to Figure 4This application embodiment also provides an atomizing core 200, including a liquid inlet substrate 210 and a heating element 100; the liquid inlet substrate 210 has a through hole 220, and the heating element 100 is disposed in the through hole 220.
[0076] In some embodiments, the liquid inlet substrate 210 is a porous ceramic body. The porous structure of the liquid inlet substrate 210 forms a capillary effect to transport the aerosol matrix to the inner wall surface of the perforation 220. After the heating element 100 is energized, it heats up and atomizes the aerosol matrix to generate atomized gas for the user to inhale.
[0077] Specifically, the heating element 100 can be a planar structure in its unfolded state, which is rolled into a cylindrical shape and placed on the inner wall surface of the perforation 220 so that the inner wall surface of the perforation 220 forms an atomizing surface.
[0078] For example, the heating element 100 is a one-piece molded structure. The heating element 100 can be made of metal sheet, and regular heating lines 5 and other parts are formed on a thin metal sheet by etching, cutting, stamping, etc. The material of the heating element 100 is generally made of alloy with high resistivity, such as iron-chromium-aluminum alloy, nickel-chromium alloy, stainless steel, titanium alloy, aluminum alloy, iron alloy, etc.
[0079] For example, the heating element 100 can be laid flat on the inner wall surface of the perforation 220. Alternatively, the heating element 100 can also be integrally formed and attached to the inner wall surface of the perforation 220 by means of sintering or the like.
[0080] The atomizing core 200 of this application adopts the heating element 100 mentioned above. The heating element 100 heats evenly and has good heat dissipation capacity, effectively avoiding excessive local temperature, reducing the coking rate during atomization, thereby reducing energy consumption and extending the service life of the atomizing core 200.
[0081] Thirdly, refer to Figure 5 This application also provides an atomizer 300, which includes a main body 310 having a liquid storage chamber 320 and an atomizing core 200 disposed in the main body 310; the liquid storage chamber 320 and the atomizing core 200 are in liquid inlet communication.
[0082] In some embodiments, this application also provides an electronic atomizing device, including a power module (not shown) and an atomizer 300, wherein the power module is used to supply power to the heating element 100 of the atomizer 300.
[0083] Specifically, the first electrode 1 and the second electrode 2 of the heating element 100 are respectively used for electrical connection with the power supply module; the power supply module is electrically connected to the heating element 100 through electrode conductors. The electrode conductors can be, but are not limited to, wires, spring pins, pins, and other electrical connectors.
[0084] In some embodiments, wires 11 are connected to the first electrode 1 and the second electrode 2 respectively to facilitate electrical connection with the movie module.
[0085] Specifically, the liquid storage chamber 320 stores a liquid aerosol matrix, and the aerosol matrix is connected to the heating element 100 through the liquid inlet substrate 210 to meet the liquid supply to the heating element 100; the power supply module is used to electrically connect with the heating element 100. After the heating element 100 is powered on, it heats and atomizes the aerosol matrix to generate atomized gas that can be inhaled by the user.
[0086] Understandably, the electronic atomizing device of this application can be a replaceable atomizer 300, meaning the atomizer 300 and the power module are detachably connected. Alternatively, the electronic atomizing device of this application can also be a disposable electronic atomizing device, meaning the atomizer 300 and the battery module are not detachably connected. No specific limitations are made here, as long as the power module can supply power to the atomizer coil 200.
[0087] The application does not specify the model of the atomizer 300, that is, the shape of the atomizer 300 can be flask-shaped, rectangular, cylindrical, etc.
[0088] The above are merely preferred embodiments of this application and are 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.
