Abstract
Description
Technical Field
[0001] The present application relates to the field of electronic atomization technology, and in particular to a heating component and an electronic atomization device. Background Art
[0002] The heating component of the electronic atomization device is used to heat and atomize the atomizing medium to form an aerosol for the user to inhale. Usually, the atomizing medium is absorbed by the porous body in the heating component, and the porous body is heated by the heating element. The atomizing medium adsorbed in the porous body can be heated and atomized.
[0003] When the viscosity of the atomizing medium is high (such as a paste-like atomizing medium), its flow properties are poor, and there are at least two problems in the heating atomization process: on the one hand, the temperature distribution of the surface (liquid absorption surface) of the porous body that is in contact with the atomizing medium will greatly affect the uniformity of the transmission of the atomizing medium. For example, the atomizing medium in the area with higher temperature is transmitted faster, so the atomizing medium can be consumed quickly. The atomizing medium in the area with lower temperature is transmitted slower, so the consumption rate of the atomizing medium is slow, which will lead to problems such as the atomizing medium remaining and not being completely consumed. If forced to be sucked at this time, it will cause a burnt smell. On the other hand, high-viscosity atomizing media are usually mixed with more components, and the boiling points of different components vary greatly. If the temperature of the heating element is too high, the low-boiling-point substances in the mixed atomizing medium will be attenuated or destroyed. If the temperature of the heating element is too low, the overall atomization amount will be less. Therefore, a heating component is needed that can both generate heat evenly on the liquid absorption surface and take into account the atomization of the atomizing medium at different temperatures.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "multiple" means two or more.
[0032] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0033] First, see Figure 1 、 Figure 3 and Figure 4The present application provides a heating assembly 100, comprising a pot body 40, a porous body 10, a heating element 20 and a rigid body 30. A receiving cavity 41 is formed in the pot body 40, and an oil lowering opening 42 connected to the receiving cavity 41 is provided at one end of the pot body 40. The porous body 10 is arranged at the oil lowering opening 42. The porous body 10 has a liquid absorption surface 11 exposed at the oil lowering opening 42 and an atomizing surface 12 facing away from the liquid absorption surface 11. The heating element 20 is arranged at the atomizing surface 12. The heating element 20 includes a first heating section 21 and a second heating section 22. The heating power of the second heating section 22 is greater than the heating power of the first heating section 21. The rigid body 30 is wrapped around at least the outer peripheral side surface of the porous body 10 and the outer peripheral side surface of the pot body 40, and is in contact with the pot body 40 and the porous body 10. The present application provides two heating sections on the heating element 20, and the heating power of the two heating sections is different. In this way, different temperature zones can be formed on the atomization surface 12. When the atomization medium containing multiple components is heated and atomized on the atomization surface 12, the lower temperature area on the atomization surface 12 can heat and atomize the components with low boiling points in the atomization medium, thereby preventing the low boiling point components from being largely attenuated or destroyed due to high temperature heating, thereby preserving the mouthfeel of the flavor substances. The higher temperature area formed on the atomization surface 12 can enable the atomization medium to form a larger atomization volume. Therefore, the simultaneous provision of high-temperature and low-temperature areas on the atomization surface 12 can improve the mouthfeel of the aerosol formed by the atomization medium in terms of both preserving the atomization of low-boiling point substances and forming a sufficient atomization volume, thereby enhancing the user experience.
[0034] In addition, the present application also wraps the outer peripheral side surfaces of the porous body 10 and the pot body 40 with a rigid body 30. In this way, not only can the heat conduction effect of the rigid body 30 be used to quickly transfer heat from the atomizing surface 12 of the porous body 10 along the outer peripheral side surfaces of the porous body 10 and the pot body 40 to the liquid absorption surface 11 of the porous body 10, but also the temperature field on the surface of the porous body 10 is evenly distributed, thereby ensuring that the atomized medium in the accommodating cavity 41 is evenly heated and consumed at a uniform rate, thereby avoiding the local temperature of the liquid absorption surface 11 of the porous body 10 being too high and causing a burnt smell. The wrapping effect of the rigid body 30 can also be used to assemble and connect the porous body 10 and the pot body 40, thereby avoiding the use of a connection scheme in which the rigid body 30 and the porous body 10 are sintered integrally, thereby solving the problem of the porous body 10 and the rigid body 30 being easily separated after sintering due to the inconsistent shrinkage rates of the materials, and also solving the problem of the brittle porous body 10 being easily cracked after sintering shrinkage.
[0035] Optionally, in addition to wrapping around the outer peripheral side surfaces of the porous body 10 and the pot body 40 , the rigid body 30 may also extend to the atomizing surface 12 of the porous body 10 , which is not limited here.
[0036] Optionally, the porous body 10 may be porous ceramics, porous glass, etc., or other synthetic or natural materials with a porous structure.
[0037] In some specific examples, the thermal conductivity of the porous body 10 is 0.8 to 2.5 W / (m·K), such as: 0.8 W / (m·K), 1.2 W / (m·K), 1.5 W / (m·K), 2 W / (m·K), 2.5 W / (m·K), etc.
[0038] In some embodiments, the thermal conductivity of the rigid body 30 is much greater than the thermal conductivity of the porous body 10. In this way, the rapid thermal conductivity of the rigid body 30 can be utilized to quickly transfer the heat from the atomizing surface 12 of the porous body 10 to the liquid absorption surface 11 of the porous body 10, so that the temperature field distribution of the liquid absorption surface 11 of the porous body 10 is more uniform.
[0039] In some specific examples, the rigid body 30 can be made of a hard metal material, such as stainless steel or other alloys. The pot body 40 is made of a hard material, including but not limited to hard non-metallic materials such as ceramics, glass, and plastic, or hard metal materials such as aluminum and stainless steel.
[0040] It should be noted that the atomizing surface 12 of the porous body 10 can be set according to the size of the pot body. As an example, a large-sized pot body 40 is correspondingly provided with a larger porous body 10, and accordingly has a larger atomizing surface 12, which is conducive to the atomization of low-boiling point flavor substances and thus enhances the taste. Under the same power, since the maximum temperature of the large-sized pot body 40 is lower than that of the small-sized pot body 40, the large-sized pot body 40 has a stronger ability to resist dry burning, which is conducive to reducing the risk of burnt taste. The small-sized pot body 40 is correspondingly provided with a smaller porous body 10, so its atomizing surface 12 is smaller and the heating effect is more concentrated, the atomization amount is relatively large, and the temperature of the liquid absorption surface 11 is more uniform, which is conducive to reducing the risk of residual atomized medium.
[0041] In this embodiment, the actual size of the pot body 40 is not limited to a specific numerical value. Those skilled in the art can flexibly set the actual size of the pot body 40 according to design requirements. Accordingly, the size of the porous body 10 and the size of the heating element 20 can also be specifically set according to the size change of the pot body 40. In some embodiments, the atomizing surface 12 includes a first area (not shown) and a second area (not shown), the second area is arranged around the periphery of the first area, the first heating section 21 is arranged in the first area, and the second heating section 22 is arranged in the second area. In this way, the second heating section 22 can be arranged around the first heating section 21. On the one hand, with respect to the atomizing surface 12, two temperature zones can be formed: a central region and a peripheral region. The central region of the atomizing surface 12 can have a higher temperature, which helps to increase the atomization volume of the entire atomizing surface 12 and ensure sufficient temperature and atomization efficiency. On the other hand, the peripheral region of the atomizing surface 12 has a relatively lower temperature, which helps to promptly atomize the lower-boiling-point components in the atomizing medium, preventing the attenuation or destruction of low-boiling-point substances due to excessive temperature, and ensuring that the low-boiling-point flavor substances in the atomizing medium are effectively atomized, resulting in a better taste. On the other hand, with respect to the liquid absorption surface 11, the liquid absorption surface 11 is heated by heat conduction after the atomizing surface 12 heats up. However, because the outer peripheral side of the porous body 10 contacts the rigid body 30, some of the heat in the porous body 10 is dispersed into the rigid body 30 and the pot body 40, resulting in faster heat dissipation in the peripheral region of the liquid absorption surface 11, while the central region of the liquid absorption surface 11 has a relatively higher temperature. Therefore, by setting the second heating section 22 with a larger heating power of the heating element 20 in the second area of the atomizing surface 12, it is helpful to quickly heat the periphery of the liquid absorption surface 11, thereby compensating for the heat dissipation difference between the peripheral area and the central area of the liquid absorption surface 11, making the temperature distribution of the liquid absorption surface 11 more uniform, and ensuring that the atomized medium in the middle area and the peripheral area of the liquid absorption surface 11 can be consumed at approximately the same rate, so as to solve the problem of the atomized medium remaining in the low temperature area or producing a burnt smell in the high temperature area.
[0042] Optionally, the first heating segment 21 and the second heating segment 22 can be arranged as one body or as a separate body. For example, when the two are arranged as one body, they can be connected in series, and the first heating segment 21 and the second heating segment 22 are arranged to have different conductive cross-sectional areas, so as to control the two heating segments to have different heating powers. When the two are arranged separately, the same circuit can be used to energize them. At this time, the two heating segments can be arranged in parallel. Of course, two different sets of circuits (electrodes) can also be used to power the first heating segment 21 and the second heating segment 22 respectively, which is not limited here. The following will be explained by taking the first heating segment 21 and the second heating segment 22 arranged in series as an example.
[0043] In some embodiments, the first heating segment 21 and the second heating segment 22 are arranged in series, and the cross-sectional area of the heating wire of the first heating segment 21 is larger than the cross-sectional area of the heating wire of the second heating segment 22. According to Joule's law, the greater the resistance of a conductor, the more heat is generated by the current passing through the conductor. Therefore, the smaller the cross-sectional area of the heating wire, the greater its resistance. Under the premise that the first heating segment 21 and the second heating segment 22 are connected in series, the second heating segment 22 can generate more heat, thereby achieving the effect that the heat in the second area of the atomizing surface 12 is greater than that in the first area, so that the peripheral temperature of the liquid suction surface 11 is roughly the same as the temperature of the central area, making the temperature distribution of the liquid suction surface 11 more uniform. It can be understood that the first heating segment 21 and the second heating segment 22 are arranged in series, which can simplify the structure of the entire heating element 20 and simplify the assembly between the heating element 20 and the porous body 10. For example, the first heating segment 21 and the second heating segment 22 can be arranged in one piece, and the heating element 20 can be a metal sheet. The heating element 20 can be formed by etching, laser engraving, or stamping, and the heating element 20 and the porous body 10 can be connected by integral sintering. Of course, in other examples, the heating element 20 may also be a heating coating or a heating film layer formed on the atomizing surface 12 by coating or printing, which is not limited here.
[0044] In some embodiments, the heating element 20 includes two second heating segments 22, and both ends of the first heating segment 21 are connected in series with the two second heating segments 22. With this arrangement, while satisfying the temperature zone setting of the atomizing surface 12, the first heating segment 21 and the two second heating segments 22 can better cover the entire atomizing surface 12, fully utilizing the space of the atomizing surface 12, thereby improving the space utilization and heating efficiency of the atomizing surface 12.
[0045] Of course, as an alternative example, the first heating segment 21 can also be set in the first area of the atomizing surface 12, and the heating body 20 is provided with multiple second heating segments 22, and the multiple second heating segments 22 are arranged around the first heating segment 21.
[0046] In some embodiments, see Figure 1 and Figure 2 The atomizing surface 12 is circular, the first heating section 21 comprises a straight line segment, the center of the atomizing surface 12 is located in the straight line segment, and the second heating section 22 comprises an arc segment, which is connected in series at both ends of the straight line segment and extends along the circumference of the atomizing surface 12. In this way, the straight line segments and the arc segments can be used to better cover the circular atomizing surface 12, and an appropriate spacing can be ensured between the straight line segments and the arc segments to avoid short circuits.
[0047] Of course, in other examples, the shape of the atomizing surface 12 may not be limited to a circle. For example, the atomizing surface 12 may also be a rectangle, a polygon, an ellipse or other irregular shapes. In this case, the first heating section 21 may pass through the geometric center of the atomizing surface 12, and the second heating section 22 may be arranged along the shape of the periphery of the atomizing surface 12, thereby achieving a heating effect on the peripheral area (second area) of the atomizing surface 12.
[0048] In some embodiments, the heating element 20 is provided with a plurality of cutouts 23, which are spaced apart along the extension direction of the heating element 20. Thus, two parallel heating circuits are formed on either side of the cutouts 23, and a connection point 24 is formed between two adjacent cutouts 23. This connection point 24 can increase the strength of the heating element 20 and prevent deformation. Furthermore, the connection point 24 can divide the entire, relatively wide heating element 20 into multiple heating lines, preventing the formation of localized high-temperature hot spots within the heating element 20, thereby ensuring a more uniform temperature during heating of the heating element 20.
[0049] In some embodiments, along the direction perpendicular to the extension of the heating element 20 and parallel to the atomizing surface 12, the heating element 20 forms two heating circuits on both sides of the incision 23, and along the extension direction of the heating element 20, the heating element 20 forms a connection point 24 between two adjacent incisions 23, and the two heating circuits are arranged in parallel through the connection point 24, and the width of the connection point 24 of the second heating section 22 gradually increases from the center to the periphery of the atomizing surface 12. With this arrangement, the connection point 24 has the effect of being narrow on the inside and wide on the outside, that is, the width of the connection point 24 is narrower on the side close to the center of the atomizing surface 12, and wider on the side close to the periphery of the atomizing surface 12. In this way, the heat transfer effect can be improved by utilizing the setting of the connection point 24 gradually widening from the inside to the outside, reducing the temperature gradient of the heating circuits on the inside and outside of the incision 23, so that the heat generation on the inside and outside of the connection point 24 tends to be consistent, thereby ensuring more uniform heat in the same heating section.
[0050] In some embodiments, the heating element 20 may further include a plurality of pins 25, which are arranged at intervals along the periphery of the heating element 20. The pins 25 can be bent and embedded in the porous body 10, so that the heating element 20 and the porous body 10 can be tightly combined to prevent the heating element 20 from being separated from the porous body 10. Alternatively, the heating element 20 and the porous body 10 can be sintered as a whole, and the pins 25 are embedded in the porous body 10 and fixed by sintering to achieve the connection and fixation of the heating element 20 and the porous body 10.
[0051] In some embodiments, the rigid body 30 includes a side wall portion 31 and an end wall portion 32. The side wall portion 31 is provided on the outer peripheral side of the porous body 10 and the pot body 40. The end wall portion 32 extends from the side wall portion 31 to the atomizing surface 12 of the porous body 10. The end wall portion 32 is provided with a mounting opening 321. The area of the atomizing surface 12 where the heating element 20 is provided is exposed at the mounting opening 321. By utilizing the mounting opening 321 of the end wall portion 32, the heating element 20 can be exposed from the mounting opening 321, thereby preventing the heating element 20 from contacting the metal rigid body 30 and causing a short circuit. By utilizing the end wall portion 32 extending to the atomizing surface 12 of the porous body 10, on the one hand, the porous body 10 can be fixed to the pot body 40 in the axial direction z of the pot body 40, thereby preventing the porous body 10 from falling out. For example, the porous body 10 and the rigid body 30 can be assembled first, with the end wall 32 of the rigid body 30 supporting the porous body 10, and then the side wall 31 of the rigid body 30 is connected to the outer peripheral side of the pot body 40 by interference fit, thereby connecting the rigid body 30 and the pot body 40, thereby achieving the assembly of the porous body 10, the rigid body 30, and the pot body 40. On the other hand, the heat of the porous body 10 can be quickly transferred to the side wall 31 by the end wall 32 of the rigid body 30, and the heat is then transferred along the side wall 31 to the outer peripheral side of the pot body 40. Subsequently, the pot body 40 can quickly heat the atomized medium near the inner wall surface of the accommodating cavity 41, so that the atomized medium at the liquid absorption surface 11 of the porous body 10 is heated more evenly.
[0052] In some embodiments, the heating component 100 further includes a flexible body 50, which is clamped between the pot body 40 and the porous body 10. A limiting step 43 is provided on the outer peripheral side of the pot body 40, and the side wall portion 31 abuts against the limiting step 43. By providing the flexible body 50, the sealing performance between the porous body 10 and the pot body 40 can be improved, and the problem of leakage of the atomized medium from the gap between the pot body 40 and the porous body 10 can be avoided. By providing the limiting step 43, when the rigid body 30 is loaded into the pot body 40, the limiting step 43 and the side wall portion 31 of the rigid body 30 can be used to abut against each other to control the assembly stroke of the rigid body 30, thereby controlling the compression amount of the flexible body 50, avoiding excessive compression of the flexible body 50, and causing the porous body 10 to be subjected to excessive extrusion force and cracking, thereby ensuring that the heating component 100 has good sealing and reliability.
[0053] For example, the flexible body 50 can be made of flexible or elastic sealing materials, such as rubber, silicone, etc., which can not only protect the porous body 10 and prevent the porous body 10 from colliding with the pot body 40, but also play a sealing role to prevent the atomized medium from leaking from the gap between the pot body 40 and the porous body 10.
[0054] Optionally, the flexible body 50 may not only be clamped between the pot body 40 and the porous body 10 , but a portion of the flexible body 50 may also be clamped between the outer periphery of the pot body 40 and the inner side surface of the rigid body 30 , which is not limited here.
[0055] In some embodiments, the atomizing surface 12 is provided with a mounting boss 123, which extends from the mounting opening 321. The heating element 20 is arranged on the surface of the mounting boss 123, and the end wall portion 32 is flush with the surface of the mounting boss 123, or the surface of the mounting boss 123 protrudes from the end wall portion 32. By utilizing the matching relationship between the mounting boss 123 and the mounting opening 321, on the one hand, the contact area between the rigid body 30 and the porous body 10 can be further increased, thereby improving the stability of the two after assembly. The mounting boss 123 and the mounting opening 321 also help to reduce the alignment error between the porous body 10 and the rigid body 30, and the coaxiality and installation accuracy after assembly. On the other hand, by setting the mounting boss 123, the atomizing surface 12 and the mounting surface of the end wall portion 32 of the rigid body 30 can be staggered in the axial direction z, thereby avoiding contact with the rigid body 30 (especially the end wall portion 32 of the rigid body 30) when welding the electrode to the atomizing surface 12, thereby avoiding short circuit caused by contact, thereby improving the reliability of the heating component 100 during the assembly and manufacturing process.
[0056] In some embodiments, please refer to Figure 5 The edge of the mounting opening 321 is spaced from the outer peripheral side of the mounting boss 123 to form a protective gap d. By setting the protective gap d, on the one hand, a sufficient distance can be left between the end wall portion 32 and the mounting boss 123 to prevent the heating element 20 from contacting the rigid body 30 and causing a short circuit. On the other hand, since the porous body 10 has a certain degree of brittleness and is prone to breakage, the protective gap d can be used to prevent the end wall portion 32 of the rigid body 30 from squeezing the mounting boss 123, thereby effectively preventing the porous body 10 from breaking and improving the manufacturing yield and reliability of the heating component 100.
[0057] In some embodiments, the inner wall surface of the accommodating chamber 41 at one end near the lower oil opening 42 is provided with a guide slope 411, and the guide slope 411 is tilted toward the lower oil opening 42. By utilizing the diversion effect of the guide slope 411, on the one hand, the atomized medium can be guided to flow smoothly along the guide slope 411 to the porous body 10, thereby reducing the atomized medium residue on the inner wall of the accommodating chamber 41. On the other hand, compared with the vertically arranged inner wall surface of the accommodating chamber 41, setting the inner wall surface as the guide slope 411 can increase the contact area between the pot body 40 and the atomized medium, which helps to quickly heat the atomized medium on the inner wall surface of the accommodating chamber 41, so that the heating consumption rate of the atomized medium is more uniform. Exemplarily, the guide slope 411 can be set as a conical surface, and the apex of the cone is set toward the lower oil opening 42.
[0058] In some embodiments, the end surface of the edge of the oil lower opening 42 facing the porous body 10 is provided with a mounting groove 421, and the flexible body 50 is disposed in the mounting groove 421. When the pot body 40, the flexible body 50, and the porous body 10 are assembled, one side of the flexible body 50 abuts against the bottom of the mounting groove 421, and the other side of the flexible body 50 abuts against the liquid absorption surface 11 of the porous body 10. On the one hand, this can achieve a sealing effect between the pot body 40 and the porous body 10, preventing the atomized medium from leaking from the assembly gap between the pot body 40 and the porous body 10. On the other hand, the flexible body 50 can prevent the edge of the oil lower opening 42 of the pot body 40 from directly contacting the liquid absorption surface 11 of the porous body 10, thereby reducing the risk of the porous body 10 being crushed by mutual compression between the pot body 40 and the porous body 10.
[0059] In a second aspect, the present application further provides an electronic atomization device (not shown), which includes the heating assembly 100 provided in the first aspect. The heating assembly 100 can heat the atomization medium to form an aerosol, which is released through the air outlet of the electronic atomization device for inhalation by the user.
