Abstract

Technical Field
[0001] This utility model relates to the field of electronic cigarette atomization technology, and in particular to a heating mesh and a heating element and atomizing assembly using the same. Background Technology
[0002] Electronic atomizers typically consist of a liquid guide and a heating element. Current atomizing components work by utilizing the Joule effect of the heating element to heat and atomize the liquid adsorbed on the liquid guide, forming an aerosol for the user to inhale. However, existing heating meshes suffer from uneven heating, with a concentrated temperature field in the middle area and lower temperatures at the ends. This uneven heating makes the atomizing component prone to scorching due to localized overheating, reducing its reliability and lifespan. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heating mesh that improves heating uniformity. When applied to heating elements and atomizing components, it avoids local overheating and improves reliability and service life.
[0004] The objective of this utility model is achieved through the following technical solution: A heating mesh is provided, wherein at least two identical heating areas are arranged at intervals in the vertical direction. The heating areas are arranged from left to right as a left heating area, a middle heating area, and a right heating area. The area of the middle heating area is smaller than that of the left and right heating areas. The left, middle, and right heating areas are provided with interconnected heating lines. The heating lines include a plurality of heating ribs connected at an angle to each other. A first heat dissipation rib and a second heat dissipation rib are connected at the connection points of the heating ribs. The first heat dissipation rib is connected at a connection position facing outward of its respective heating area, and the second heat dissipation rib is connected at a connection position facing outward of the adjacent heating area. The heating ribs and the second heat dissipation rib are surrounded by a plurality of through holes, and the area of the through holes gradually decreases along the direction from the middle heating area to the left and right heating areas.
[0005] In a preferred embodiment, the left heating area and the right heating area have equal areas.
[0006] In a preferred embodiment, the through hole includes a first through hole, a second through hole, and a third through hole. The first through hole is located between adjacent middle heating zones, the second through hole is located between the first and third through holes, and the third through hole is located between adjacent left or right heating zones. The area of the first through hole is larger than the area of the second through hole, and the area of the second through hole is larger than the area of the third through hole.
[0007] In a preferred embodiment, the heating ribs on the left heating area and the heating ribs on the right heating area are arranged symmetrically.
[0008] In a preferred embodiment, the angle between adjacent heating ribs on the left heating zone is smaller than the angle between adjacent heating ribs on the middle heating zone.
[0009] In a preferred embodiment, the height of the heating rib on the left heating zone is greater than the height of the heating rib on the middle heating zone, and the thickness of the heating rib on the left heating zone is the same as that of the heating rib on the right heating zone.
[0010] In a preferred embodiment, the heating rib is provided with a thermally conductive coating.
[0011] This utility model also provides a heating element, including two electrical lead pads and the aforementioned heating mesh, wherein the two electrical lead pads are connected to both sides of the heating mesh, and the two ends of the heating circuit are connected to the electrical lead pads.
[0012] This utility model also provides an atomizing component, including the heating element described above.
[0013] Compared with the prior art, the present invention has at least the following advantages: 1. The heating mesh provided by this utility model achieves precise control of heat distribution through the synergistic effect of differentiated heating area zones, connection angles and circuit layout of heating ribs, heat conduction of heat dissipation ribs, and gradient setting of through hole area. This makes the heat more evenly distributed on the entire heating mesh, improves the uniformity of heating, and can effectively solve the problem of concentrated temperature field in the middle area and low temperature at both ends of the existing heating mesh.
[0014] 2. The heating mesh of this utility model, through the setting of the first, second and third through holes, allows some of the heat in the middle heating area to be quickly dissipated through the first through hole. The second through hole serves as a transition zone, transferring the remaining heat in the middle heating area to both sides. The third through hole controls the heat dissipation of the left and right heating areas. The left and right heating areas are relatively larger than the middle heating area and have a certain heat dissipation capacity. The smaller third through hole can meet their basic heat dissipation needs and avoid the temperature from being too low due to excessive heat dissipation.
[0015] 3. The heating mesh of this utility model is applied to the atomizing component, which can provide a more stable thermal field for the atomization process, making the atomized liquid more evenly heated, thereby improving the atomization effect, making the generated droplets more uniform in size, improving the atomization quality, avoiding scorching of the atomizing component due to local overheating, and thus improving the reliability and service life of the atomizing component.

[0021] See Figure 1A heating mesh 100 is provided in which at least two identical heating areas are arranged at intervals in the vertical direction. The heating areas are arranged from left to right as a left heating area 110, a middle heating area 120, and a right heating area 130. The area of the middle heating area 120 is smaller than that of the left heating area 110 and the right heating area 130. The left heating area 110, the middle heating area 120, and the right heating area 130 are provided with interconnected heating lines. The heating lines include a number of heating ribs 140 connected at an angle to each other. A first heat dissipation rib 150 and a second heat dissipation rib 160 are connected at the connection points of the heating ribs 140. The first heat dissipation rib 150 is vertically connected to the connection position of the heating rib 140 facing the outside of its heating area. The second heat dissipation rib 160 is vertically connected to the connection position facing the inside of the adjacent heating area. The heating ribs 140 and the second heat dissipation rib 160 are surrounded by a number of through holes. The area of the through holes gradually decreases along the middle heating area 120 towards the left and right heating areas 130.
[0022] It should be noted that the heating mesh 100 divides each heating area into a left heating area 110, a middle heating area 120, and a right heating area 130. The area of the middle heating area 120 is smaller than that of the left and right heating areas 110 and 130. The smaller area of the middle heating area 120 prevents excessive heat concentration in this area after the heating circuit is energized. The larger areas of the left and right heating areas 130 can distribute more heat, initially adjusting the horizontal distribution of heat and alleviating the problem of heat accumulation in the middle area. The heating circuit within the heating area consists of several heating ribs 140 connected at angles to each other. Different connection angles will change the flow path of current and the resistance in the heating ribs 140, thereby adjusting the heat generation in each area and making the heat distribution uniform. The first heat dissipation rib 150 is connected to the connection position of the heating rib 140 facing the outside of its heating area, which can dissipate part of the heat generated in the heating area to the outside space, reducing the heat generation in the heating area. In the localized area of the heating zone, the second heat dissipation fin 160 is connected to the connection position facing the inner side of the adjacent heating zone, playing a role in heat conduction and promoting the flow and balance of heat between different areas of the heating mesh 100. Combined with the design that the area of the through holes gradually decreases along the middle heating zone 120 towards the left heating zone 110 and the right heating zone 130, on the one hand, it can control the rate of heat loss and avoid the left and right heating zones 110 and 130 from losing heat too quickly and resulting in excessively low temperatures. On the other hand, the gradient change in the area of the through holes can guide the airflow to form a specific flow pattern, so that the airflow flows orderly from the middle heating zone 120 to the left and right heating zones 130, carrying away the heat of the middle heating zone 120, while providing a certain amount of heat supplement to the left and right heating zones 110 and 130, further promoting the uniform distribution of heat throughout the heating mesh 100, accelerating the heat loss of the middle heating zone 120, and avoiding heat accumulation.
[0023] The heating mesh 100 achieves precise control of heat distribution through the differentiation of heating area, the connection angle and circuit layout of heating ribs 140, the heat conduction of heat dissipation ribs, and the gradient change of through hole area. This makes the heat more evenly distributed on the entire heating mesh 100, improves the uniformity of heating, and can effectively solve the problem of concentrated temperature field in the middle area and low temperature at both ends of the existing heating mesh 100.
[0024] In some embodiments, the left heating area 110 and the right heating area 130 have the same area, so that under the same current supply and the same resistance, the total amount of heat generated by the two areas is theoretically similar, which can further avoid the temperature difference between the left heating area 110 and the right heating area 130. Combined with the design of the smaller area of the middle heating area 120, the heat is evenly conducted from the middle heating area 120 to the left heating area 110 and the right heating area 130.
[0025] In some embodiments, the through hole is divided into a first through hole 170, a second through hole 180, and a third through hole 190. The first through hole 170 is located between adjacent middle heating areas 120, the second through hole 180 is located between the first through hole 170 and the third through hole 190, and the third through hole 190 is located between adjacent left or right heating areas. The area of the first through hole 170 is larger than the area of the second through hole 180, and the area of the second through hole 180 is larger than the area of the third through hole 190.
[0026] It should be noted that the first through-hole 170 is located between the adjacent middle heating zones 120 and has the largest area. Because the middle heating zone 120 has a relatively small area, it is prone to heat accumulation during the heating process. The larger first through-hole 170 provides a more spacious heat dissipation channel, accelerating heat loss from the middle heating zone 120 and preventing performance degradation or damage due to localized overheating. The second through-hole 180 is located between the first through-hole 170 and the third through-hole 190, with an area between the two. The third through-hole 190 is located between the adjacent left or right heating zones and has the smallest area. Thus, the mesh... The area of the through holes on the heating mesh 100 changes gradually from the middle to the left and right ends, allowing heat to be dissipated in a reasonable gradient across the entire heating mesh 100, thus improving heat dissipation efficiency. Specifically, after a portion of the heat in the middle heating zone 120 is quickly dissipated through the first through hole 170, the remaining heat is transferred to both sides through the second through hole 180. The third through hole 190 controls the heat dissipation of the left and right heating zones. The left and right heating zones have larger areas and inherent heat dissipation capabilities. The smaller third through hole 190 can meet their basic heat dissipation needs while preventing excessively low temperatures due to rapid heat dissipation. The gradually decreasing area of the second through hole 180 and the third through hole 190 also provides sufficient structural support for both ends of the heating mesh 100 while meeting heat dissipation requirements, preventing a decrease in structural strength due to excessively large through holes, and ensuring the stability and reliability of the heating mesh 100 during operation. It is also understood that there can be one or more of the first through hole 170, the second through hole 180, and the third through hole 190.
[0027] In some embodiments, the heating ribs 140 on the left heating area 110 and the heating ribs on the right heating area 130 are symmetrically arranged. Since the two heating areas have the same area, the heat distribution generated by the two heating areas when the current passes through them is also symmetrical, thereby ensuring that the temperature fields on the left and right sides of the heating mesh 100 are basically the same. This avoids the temperature deviation between the two heating areas caused by the arrangement of the heating ribs 140, and is conducive to the uniform conduction of heat from the middle heating area 120 to the heating areas on both sides.
[0028] In some embodiments, the included angle α of the adjacent heating ribs 140 on the left heating zone 110 is smaller than the included angle b of the adjacent heating ribs 140 on the middle heating zone 120, and the height h1 of the heating ribs 140 on the left heating zone 110 is greater than the height h2 of the heating ribs 140 on the middle heating zone 120. It is understandable that the angle 'a' between adjacent heating ribs 140 in the left heating zone 110 is smaller than the angle 'b' between adjacent heating ribs 140 in the middle heating zone 120. This means that the heating ribs 140 in the left heating zone 110 are arranged more closely. Under the same current, the closer arrangement will cause the heat generation per unit area in the left heating zone 110 to be relatively concentrated. Furthermore, the height h1 of the heating ribs 140 in the left heating zone 110 is greater than the height h2 of the heating ribs 140 in the middle heating zone 120, which increases the resistance of the left heating zone 110. As a result, more heat will be generated under the same current, and the heat will be distributed over a larger area within the left heating zone 110. The angle between adjacent heating ribs 140 in the middle heating zone 120 is large, and the height of the heating ribs 140 is small, resulting in relatively less heat generation, and the heat is distributed over a smaller area within the middle heating zone 120. In this way, the heat of the middle heating zone 120 and the left and right heating zones 130 can be further balanced, preventing excessive heat concentration in the middle area.
[0029] Preferably, the heating ribs 140 of the left heating zone 110 and the heating ribs 140 of the right heating zone 130 have the same thickness. In this way, the physical properties of the left and right heating zones 130 are the same, and the heat conduction process will not be hindered or accelerated by the special structure of the heating ribs 140 on one side, making the temperature field of the entire heating mesh 100 more uniform.
[0030] To quickly conduct the heat generated by the heating element 140 away, a thermally conductive coating can be provided on the heating element 140. In one embodiment, a nano-thermal conductive coating with a high thermal conductivity is used, which can reduce the accumulation of heat on the surface of the heating element 140, facilitate rapid heat conduction, and maintain long-term stability during the operation of the heating element 140.
[0031] like Figure 1 The heating element 10 includes two lead pads 200 and a heating mesh 100. The two lead pads 200 are connected to both sides of the heating mesh 100, and the two ends of the heating circuit are connected to the lead pads 200. The lead pads 200 on both sides of the heating mesh 100 and their connection to the two ends of the heating circuit help to distribute the current evenly across the heating mesh 100. With this uniform current distribution, the heating element 10 effectively solves the problem of uneven heating, where the temperature is high in the middle and low at both ends, thus improving the service life of the heating element 10.
[0032] The aforementioned heating element 10 is applied to the atomizing assembly. The heating mesh 100 can generate and conduct heat evenly, avoiding scorching of the atomizing assembly due to local overheating, thereby reducing the reliability and service life of the atomizing assembly. At the same time, the uniform heat generation and conduction provide a stable heat source for the atomization process, ensuring that the atomized liquid vaporizes at a suitable temperature, producing uniform and fine droplets, and improving the atomization quality.
[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
