Technical Field

[0001] This utility model relates to the field of atomizer component technology, specifically a heat-generating component for uniform heating. Background Technology

[0002] In the field of electronic atomizers, especially in devices that use cotton swabs as the wicking medium, preventing the swabs from drying out is a crucial technical issue. When used as a wicking medium, the cotton swab guides the atomized liquid in the reservoir to the vicinity of the heating element for heating and atomization. However, when the atomized liquid is depleted and there is no more liquid on the cotton swab for evaporation, continued operation of the heating element will lead to the cotton swab drying out.

[0003] Dry burning can damage the cotton swab and heating element themselves, and may also produce harmful gases, affecting user experience and health. Summary of the Invention

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a uniform heating component that can effectively solve the problems of uniform heating and dry burning prevention of cotton swabs mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a heat-equalizing heating component, including an oil-guiding cotton swab, a heating element surrounding the outside of the cotton swab, and pins of the heating element. The cotton swab and the heating element are provided with an isolation element to prevent the cotton swab from overheating and burning. A heat-equalizing plate is provided between the isolation element and the heating element to evenly heat the cotton swab. The mesh of the heating element is embedded into the surface of the heat-equalizing plate by ultrasonic welding.

[0006] The heat spreader comprises, from the outside to the inside, a heat-conducting inner layer, a multi-layer copper mesh layer, and a heat-conducting outer layer. The bottom part of the heat-conducting outer layer is inserted into the upper layer of the multi-layer copper mesh layer. The heat-conducting inner layer is fixedly connected to the lower surface of the multi-layer copper mesh layer. The heat-conducting outer layer is fixedly connected to the mesh of the heating element.

[0007] Furthermore, a housing is provided on the outer side of the heating element, and a vent hole is provided on the side of the housing, the vent hole penetrating the housing.

[0009] Furthermore, the insulating element is a porous ceramic component.

[0010] Furthermore, the heat-conducting inner layer of the heat spreader is made of a metal or alloy material with high thermal conductivity to optimize heat transfer efficiency.

[0011] Furthermore, the metal or alloy material of the heat-conducting inner layer includes, but is not limited to, copper, aluminum, silver, or their alloys, which can significantly improve the heat conduction speed.

[0012] Furthermore, the multilayer copper mesh layer is composed of multiple layers of fine copper mesh stacked together to provide a larger thermal contact area, thereby enhancing the uniform distribution of heat.

[0013] Furthermore, each layer of the multilayer copper mesh has a different mesh count to form a gradient structure, further optimizing the uniform transfer of heat.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This design generates heat through a heating element, and utilizes a heat-conducting inner layer, multiple copper mesh layers, and a heat-conducting outer layer to achieve efficient and uniform heat transfer.

[0021] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0022] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example

[0023] like Figure 1-4 As shown, this utility model provides a heat-equalizing heating component, including an oil-guiding cotton swab 1, a heating element 4 surrounding the outside of the cotton swab 1, and pins 5 of the heating element 4. The cotton swab 1 and the heating element 4 are provided with an isolation element 2 to prevent the cotton swab 1 from overheating and burning. A heat-equalizing plate 3 is provided between the isolation element 2 and the heating element 4 to evenly distribute the heat of the cotton swab 1. The mesh of the heating element 4 is embedded into the surface of the heat-equalizing plate 3 by ultrasonic welding.

[0024] The heat spreader 3 includes, from the outside to the inside, a heat-conducting inner layer 31, a multi-layer copper mesh layer 32, and a heat-conducting outer layer 33. The bottom part of the heat-conducting outer layer 33 is inserted into the upper layer of the multi-layer copper mesh layer 32. The heat-conducting inner layer 31 is fixedly connected to the lower surface of the multi-layer copper mesh layer 32. The heat-conducting outer layer 33 is fixedly connected to the mesh of the heating element 4.

[0025] The cotton swab 1 serves as a medium for heat transfer and oil flow. The cotton swab 1 is responsible for absorbing and transferring heat to the oil, so that the oil reaches the required temperature for subsequent operations.

[0026] The heating element 4 surrounds the outside of the cotton swab 1 and is the component that generates heat. Through the action of electric current, the heating element 4 generates heat and transfers it to the cotton swab 1 and the oil.

[0027] Pin 5 of the heating element 4 is connected to a power supply to provide a stable current supply to the heating element 4, thereby ensuring the continuous generation of heat.

[0028] The insulating element 2 is positioned between the cotton swab 1 and the heating element 4 to prevent the cotton swab 1 from overheating and burning due to direct contact with the high-temperature heating element 4. The insulating element 2 can effectively control the temperature of the cotton swab 1 and extend its service life.

[0029] The heat-conducting inner layer 31 is fixedly connected to the lower surface of the multilayer copper mesh layer 32, and is responsible for efficiently transferring heat from the heating element 4 to the multilayer copper mesh layer 32.

[0030] The multi-layer copper mesh 32 is composed of multiple layers of fine copper mesh, providing a larger thermal contact area, which helps to achieve uniform heat distribution and rapid heat transfer. At the same time, the multi-layer structure can further reduce thermal resistance and improve thermal efficiency.

[0031] The thermally conductive outer layer 33 is fixedly connected to the mesh of the heating element 4, and is responsible for transferring heat from the multi-layer copper mesh layer 32 to the cotton swab 1. The design of the thermally conductive outer layer 33 allows heat to be more evenly distributed on the cotton swab 1, avoiding localized overheating.

[0032] Ultrasonic welding is used to embed the mesh of the heating element 4 into the surface of the heat spreader 3, ensuring a tight connection and efficient heat transfer between the two.

[0033] When the heating element 4 generates heat, the heat is rapidly transferred through the heat-conducting outer layer 33 to the multi-layer copper mesh layer 32, and after being evenly dispersed by the multi-layer copper mesh layer 32, it is transferred to the heat-conducting inner layer 31. This process ensures that the heat is evenly distributed inside the heat spreader 3.

[0034] The presence of the isolation element 2 effectively prevents direct contact between the cotton swab 1 and the heating element 4, thereby avoiding the phenomenon of overheating and dry burning of the cotton swab 1 due to direct contact with the high-temperature heating element 4.

[0035] By embedding the mesh of the heating element 4 into the surface of the heat spreader 3 through ultrasonic welding, a tight connection and efficient heat transfer between the two are ensured. This not only improves the heat transfer efficiency but also allows the cotton swab 1 to reach the required heating temperature more quickly, thereby optimizing the heating efficiency.

[0036] See Figure 2 The heating element 4 is provided with a housing 6 on its outer side, and a vent 7 is provided on the side of the housing 6, the vent 7 penetrating the housing 6.

[0037] The housing 6 acts as a barrier to isolate the heat generated by the heating element 4, preventing the heat from being directly transferred to the external environment, thereby improving the safety and stability of the component and providing necessary support and fixation for the entire component.

[0038] The function of the vent 7 is to allow gas inside the housing 6 to escape. When the heating element 4 is working, it produces atomized gas, and the vent 7 ensures that the gas inside the housing 6 can be smoothly discharged.

[0039] See Figure 2 The vent 7 is a long, rounded rectangular vent 7.

[0040] The elongated design allows the vent 7 to have a larger opening area, thus enabling more efficient discharge of gas from inside the housing 6. This helps reduce gas buildup inside the housing 6, preventing safety issues caused by excessive gas pressure. The rounded rectangular shape reduces resistance during gas discharge, allowing gas to flow out more smoothly and avoiding eddies or backflow at the vent 7, thereby improving gas discharge efficiency.

[0041] The elongated, rounded rectangular vent 7 design can improve the structural strength of the shell 6 while ensuring gas discharge and heat dissipation. Compared with other shapes of vent 7, the rounded rectangular design can reduce stress concentration in the shell 6 under stress, thereby improving the shell 6's resistance to deformation and fracture.

[0042] The isolation component 2 is a porous ceramic component.

[0043] Porous ceramic materials possess excellent thermal insulation properties, effectively mitigating direct heat transfer. In the heat equalization heating component, the porous ceramic insulating element 2 prevents the high temperature generated by the heating element 4 from being directly transferred to the cotton swab 1, thereby avoiding overheating and dry burning of the cotton swab 1.

[0044] By precisely controlling the porosity and structure of porous ceramic materials, their thermal conductivity can be further adjusted to meet the temperature control requirements of different application scenarios.

[0045] The porous structure of the porous ceramic insulating element 2 helps to distribute heat evenly. When heat is transferred from the heating element 4 to the porous ceramic insulating element 2, the heat diffuses and is evenly distributed between the pores, thereby reducing the accumulation of heat in local areas. This helps to ensure that the cotton swab 1 is heated evenly during the heating process, improving heating efficiency and stability.

[0046] Promotes gas flow and heat dissipation:

[0047] The porous structure of the porous ceramic insulating element 2 facilitates gas flow and heat dissipation. During heating, the porous ceramic insulating element 2 allows gas to flow through its pores, thereby carrying away some heat and improving heat dissipation efficiency.

[0048] The heat-conducting inner layer 31 of the heat spreader 3 is made of a metal or alloy material with high thermal conductivity to optimize heat transfer efficiency.

[0049] Metals or alloys with high thermal conductivity have excellent heat transfer capabilities. When the heating element 4 generates heat, these materials can quickly transfer the heat from the heating element 4 to other parts of the heat spreader 3, thereby achieving a uniform heat distribution. This efficient heat transfer characteristic helps to reduce heat loss during the transfer process, improve heat utilization, and thus optimize the overall performance of the heat spreader assembly.

[0050] Due to the rapid heat conduction capability of the high thermal conductivity material, the heat-conducting inner layer 31 of the heat spreader 3 can quickly diffuse heat to the entire heat spreader 3, ensuring that the heat is evenly distributed on the heat spreader 3. This temperature uniformity helps to avoid the problem of local overheating or uneven temperature, thereby improving the heating efficiency and stability of the cotton swab 1.

[0051] The high thermal conductivity material can quickly respond to the heat changes generated by the heating element 4, rapidly transferring heat to other parts of the heat spreader 3. This rapid response characteristic helps the heat spreader assembly achieve faster and more accurate temperature control during the heating process, thereby improving heating efficiency and precision.

[0052] By optimizing heat transfer efficiency, the thermally conductive inner layer 31 made of high thermal conductivity material helps improve the overall performance of the heat-generating component, including performance improvements such as increased heating efficiency, reduced energy consumption, and improved temperature control accuracy, thereby meeting a wider range of application needs.

[0053] The metal or alloy material of the thermally conductive inner layer 31 includes, but is not limited to, copper, aluminum, silver or their alloys, which can significantly improve the heat conduction speed.

[0054] Copper, aluminum, silver, or their alloys, when used as materials for the thermally conductive inner layer 31, can significantly improve the heat conduction speed, enhance the thermal stability and response speed of the heat-generating component, and simultaneously improve corrosion resistance.

[0055] The multilayer copper mesh layer 32 is composed of multiple layers of fine copper mesh to provide a larger thermal contact area, thereby enhancing the uniform distribution of heat.

[0056] The multi-layered copper mesh layer 32, by stacking multiple layers of fine copper mesh, greatly increases the thermal contact area, allowing heat to come into contact with more copper mesh surfaces during transfer, thus achieving more efficient heat transfer. This helps to quickly and evenly distribute the heat generated by the heating element 4 across the entire heat spreader 3, improving heat conduction efficiency.

[0057] The design of the multi-layer copper mesh 32 also increases the structural strength of the heat spreader 3. Because copper mesh itself possesses a certain strength and toughness, the multiple layers stacked together form a more robust structure. This increased structural strength helps ensure the stability and reliability of the heat spreader 3 under prolonged high-temperature operating conditions.

[0058] Each layer of the multi-layer copper mesh 32 has a different mesh count to form a gradient structure, further optimizing the uniform transfer of heat.

[0059] The gradient structure of the multi-layer copper mesh 32 can guide heat transfer along a specific path, ensuring that heat can be more evenly distributed across the entire heat spreader 3 during the transfer process.

[0060] The different mesh counts of each layer of copper mesh mean that the size and distribution of the apertures are also different. This helps to form more complex flow paths during heat transfer, thereby improving the uniformity and efficiency of heat transfer.

[0061] The first layer, near the evaporation zone:

[0062] Mesh size: Approximately 100 mesh. The main function of this layer is to quickly absorb heat from the evaporation zone and allow the coolant to pass through smoothly after vaporization.

[0063] Aperture: Relatively large to ensure that the coolant filling the multilayer copper mesh layer 32 can flow and vaporize smoothly.

[0064] Intermediate layer:

[0065] Mesh size: From 150 mesh to 250 mesh. The main function of this layer or multiple layers is to provide a transition, ensuring that the coolant can gradually slow down and release heat during the recirculation process.

[0066] Orifice size: gradually decreases to increase capillary force and promote coolant return.

[0067] The last layer, near the condensation zone:

[0068] Mesh size: 300 mesh or higher. The main function of this layer is to provide sufficient capillary force to ensure that the coolant can quickly flow back to the evaporation zone from the condensation zone.

[0069] Orifice size: Minimum, to maximize capillary force.

[0070] This gradient structure helps reduce energy loss during heat transfer and improves heat transfer efficiency.

[0071] In this embodiment, the porous ceramic isolator separates the heating element's mesh from the cotton swab, preventing the cotton swab from directly contacting the heating element and causing excessive temperature. The heat spreader set between the heating element's mesh and the porous ceramic isolator ensures that the temperature conducted to the surface of the cotton swab is uniform, preventing local overheating. The heat spreader also serves as a buffer to prevent the mesh temperature from fluctuating and affecting the atomization effect. The heat spreader smooths out the peaks and valleys of the temperature conducted to the surface of the cotton swab.
