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. After the porous body is heated, the atomizing medium adsorbed in the porous body can be heated and atomized.

[0003] Due to the influence of factors such as the material, thermal conductivity, heating element and arrangement structure of the porous body, there is a problem of uneven temperature field distribution on the contact surface between the porous body and the atomizing medium. For an atomizing medium with greater viscosity and poor fluidity, the atomizing medium has a problem of uneven heating on the surface of the porous body, which leads to inconsistent consumption rates of the atomizing medium on the surface of the porous body. In high-temperature areas, it is easy to produce a burnt smell due to overheating problems, thereby affecting the taste of use. In the related art, a rigid body sintered into one with the porous body can be provided on the basis of the porous body, and the heat equalization effect of the rigid body is utilized to make the temperature field on the surface of the porous body uniformly distributed. However, due to the different materials of the rigid body and the porous body, the heating shrinkage rates of the two themselves are different. Therefore, when the two are sintered into one, problems such as separation and cracking of the porous body are prone to occur. Utility Model Content

[0011] In certain embodiments of the present application, an inner wall surface of the accommodating cavity close to the first end is provided with a guide slope, and the guide slope is inclined toward the oil discharge opening.

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, please refer to Figure 1 、 Figure 3 and Figure 5The present application provides a heating assembly 100, comprising a pot body 40, a porous body 10, a rigid body 30, and a flexible body 50. The pot body 40 has a receiving cavity 41 formed therein. The pot body 40 has a first end 42 and a second end 43 opposite to each other. The first end 42 is provided with an oil lowering opening 421 connected to the receiving cavity 41. The porous body 10 is disposed at the first end 42, with at least a portion of the porous body 10 exposed at the oil lowering opening 421. 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 first end 42, and is in contact with the pot body 40 and the porous body 10. At least a portion of the flexible body 50 is clamped between the first end 42 and the porous body 10. It is understood that the accommodating cavity 41 of the pot body 40 is used to store the atomized medium (e.g., a paste-like, semi-solid, and highly viscous atomized medium). The porous body 10 itself has pores that allow the atomized medium to penetrate. The portion of the porous body 10 surface exposed to the oil lowering opening 421 (the liquid absorption surface 11) absorbs the atomized medium. When the porous body 10 is heated, the atomized medium is heated and atomized to form aerosol particles for release. The heating surface 12 of the porous body 10 is typically located on the side opposite the liquid absorption surface 11. Therefore, the present application wraps the rigid body 30 around the outer peripheral side surfaces of the porous body 10 and the outer peripheral side surfaces of the first end 42. In this way, not only can the heat conduction effect of the rigid body 30 be used to quickly transfer heat from the heating surface 12 of the porous body 10 along the outer peripheral side surfaces of the porous body 10 and the outer peripheral side surfaces of the pot body 40 to the liquid absorption surface 11 of the porous body 10, thereby making the temperature field on the surface of the porous body 10 uniformly distributed, thereby ensuring that the atomized medium in the accommodating cavity 41 is evenly heated and consumed at a uniform rate, avoiding the local excessive temperature of the liquid absorption surface 11 of the porous body 10 causing a burnt smell. Utilizing the wrapping effect of the rigid body 30, the porous body 10 and the pot body 40 can also be assembled and connected, 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 inconsistent material shrinkage rates, and also solving the problem of the brittle porous body 10 being easily cracked after sintering shrinkage. By providing the flexible body, a buffering effect can be played between the porous body 10 and the pot body 40 , thereby preventing the porous body 10 from being broken due to collision or extrusion between the porous body 10 and the first end 42 of the pot body 40 .

[0034] Optionally, in one example, the porous body 10 can be entirely disposed in the lower oil opening 421, so that at least one surface of the porous body 10 is entirely used to absorb the atomized medium. Of course, in another example, a portion of the structure of the porous body 10 (such as the peripheral portion) can be disposed outside the lower oil opening 421, so that only a portion of the surface of the porous body 10 (such as the central area portion) is exposed in the lower oil opening 421. In addition to being wrapped around the outer peripheral side surface of the porous body 10 and the outer peripheral side surface of the first end 42 of the pot body 40, the rigid body 30 can also extend to the surface of the porous body 10 that is away from the lower oil opening 421, which is not limited here. The flexible body 50 can not only be clamped between the first end 42 and the porous body 10, but a portion of the flexible body 50 can also be clamped between the outer periphery of the first end 42 and the inner side surface of the rigid body 30, which is not limited here.

[0035] Optionally, the porous body 10 may be porous ceramics, porous glass, etc., or other synthetic or natural materials with a porous structure.

[0036] 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.

[0037] In some embodiments, the thermal conductivity of the rigid body 30 is much greater than that of the porous body 10. This rapid thermal conductivity of the rigid body 30 can be utilized to rapidly transfer heat from the self-heating surface 12 of the porous body 10 to the liquid absorption surface 11 of the porous body 10, thereby achieving a more uniform temperature distribution on the liquid absorption surface 11 of the porous body 10. In some specific examples, the thermal conductivity of the rigid body 30 is 5 to 25 times that of the porous body 10. For example, the thermal conductivity of the rigid body 30 is 5, 10, 15, 20, or 25 times that of the porous body 10.

[0038] In some embodiments, 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. The pot body 40 can be made of a material with a thermal conductivity greater than that of the rigid body 30. In some specific examples, the thermal conductivity of the pot body 40 can be 120 to 210 W / (m·K), for example, 120 W / (m·K), 150 W / (m·K), 180 W / (m·K), 200 W / (m·K), 210 W / (m·K), etc. The specific pot body can be made of aluminum or aluminum alloy. By making the thermal conductivity of the pot body 40 much greater than that of the rigid body 30, the heat transferred from the rigid body 30 can be transferred to the atomizing medium through the inner wall surface of the accommodating cavity 41.

[0039] In some specific embodiments, 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.

[0040] In some embodiments, the heating assembly 100 further includes a heating element 20. The porous body 10 has a liquid absorption surface 11 exposed at the lower oil opening 421 and a heating surface 12 facing away from the liquid absorption surface 11. The heating element 20 is disposed on the heating surface 12. The rigid body 30 includes a side wall portion 31 and an end wall portion 32. The side wall portion 31 is disposed on the outer peripheral side of the porous body 10 and the first end 42. The end wall portion 32 extends from the side wall portion 31 to the heating surface 12 of the porous body 10. The end wall portion 32 is provided with a mounting opening 321. The area of the heating surface 12 where the heating element 20 is disposed is exposed through the mounting opening 321. The mounting opening 321 of the end wall portion 32 allows the heating element 20 to be exposed through the mounting opening 321, thereby preventing the heating element 20 from contacting the metallic rigid body 30 and causing a short circuit. By extending the end wall portion 32 to the heating surface 12 of the porous body 10, the porous body 10 can be fixed to the pot body 40 in the axial direction z of the pot body 40 (i.e., from the first end 42 to the second end 43 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, and the end wall portion 32 of the rigid body 30 can be used to support the porous body 10. Then, the side wall portion 31 of the rigid body 30 can be connected to the outer peripheral side surface of the first end 42 of the pot body 40 by interference fit, thereby connecting the rigid body 30 and the pot body 40, thereby completing 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 conducted to the side wall portion 31 by using the end wall portion 32 of the rigid body 30, and the heat is then transferred along the side wall portion 31 to the outer peripheral side surface of the first end 42 of the pot body 40. Subsequently, the first end 42 of the pot body 40 can quickly heat the atomized medium located near the inner wall surface of the accommodating cavity 41, so that the atomized medium on the liquid absorption surface 11 of the porous body 10 is heated more evenly.

[0041] In some embodiments, at least a portion of the edge of the oil lower opening 421 is in contact with the porous body 10. In this way, the heat of the porous body 10 can be directly transferred to the inner wall surface of the accommodating cavity 41 through the edge of the oil lower opening 421 (that is, the end surface of the first end 42 of the pot body 40), thereby shortening the heat transfer path and improving the heat transfer efficiency of the porous body 10 to the pot body 40. It is understandable that the edge of the oil lower opening 421 can be in direct contact with the porous body 10 or indirect contact. For example, by controlling the assembly gap between the porous body 10 and the pot body 40, the liquid absorption surface 11 of the porous body 10 is in contact with the end surface of the first end 42 of the pot body 40, which is conducive to the heat transfer to the pot body 40 through the liquid absorption surface 11. Or in other examples, a certain gap is left after the porous body 10 and the pot body 40 are assembled, and the gap can be filled with the atomized medium. The heat of the porous body 10 is transferred to the atomized medium in the gap, and then transferred to the pot body 40. The pot body 40 can further transfer the heat to the atomized medium at the inner wall of the accommodating cavity 41.

[0042] It is understood that, using the heating assembly 100 provided in this embodiment, heat is transferred from the heating surface 12 of the porous body 10 to the liquid absorption surface 11 via at least the following pathways. The first pathway is heat transfer within the porous body 10 along direction z. This heat is typically transferred to the projected area of the heating element 20 along direction z onto the liquid absorption surface 11, thereby heating the atomized medium located on the surface of this area. The second pathway is heat diffusion laterally along the heating surface 12 of the porous body 10. The heat diffuses from the heating element 20 toward the periphery of the porous body 10 and is conducted to the end wall 32 of the rigid body 30. The heat is then transferred along the side wall 31 to the inner wall of the accommodating cavity 41 of the pot body 40, thereby heating the atomized medium located near the inner wall of the accommodating cavity 41. The third pathway is similar to the second pathway, except that after the heat is transferred to the periphery of the porous body 10, it is transferred along direction z to the liquid absorption surface 11 of the porous body 10 and the edge of the oil lowering opening 421 of the pot body 40, thereby heating the atomized medium located at the edge of the oil lowering opening 421. Through these three heat conduction paths, heat from the heating surface 12 of the porous body 10 can be quickly transferred to the liquid absorption surface 11, resulting in a uniform temperature distribution on the liquid absorption surface 11 of the porous body 10, and the atomized medium can be evenly heated and consumed. For atomized media with poor fluidity, this effectively solves the problem of uneven atomized medium consumption rate, avoiding the problem of a burnt smell caused by localized high temperatures, or insufficient atomization and atomized medium residue caused by areas of insufficient temperature.

[0043] For example, the porous body 10 can be configured in a cylindrical (or disc-shaped), block-shaped, prismatic, etc., that is, the cross-sectional shape of the porous body 10 can be circular, rectangular, polygonal, etc., or elliptical or other irregular shapes. Figure 3As shown in the figure), when the porous body 10 is prismatic, the axis direction of the porous body 10 can be parallel to the direction z. For example, the heating element 20 can be a heating coating formed by coating or printing on the heating surface 12 of the porous body 10, or it can be a metal sheet sintered into an integral body with the porous body 10. The metal sheet can be formed by etching, laser engraving, or stamping. The following will describe the heating element 20 in the form of a metal sheet.

[0044] Optionally, see Figure 2 and Figure 5 The heating element 20 includes an electrode portion 21 and a heating portion 22. The electrode portion 21 is arranged at both ends of the heating portion 22. The heating portion 22 is bent and extended along the first direction x on the heating surface 12, and the extension length along the second direction y gradually decreases from the center of the heating surface 12 to the periphery, wherein the second direction y is perpendicular to the first direction x. That is, the heating portion 22 is bent back and forth along the first direction x in a serpentine manner. With this arrangement, on the one hand, the area of the heating surface 12 can be fully utilized, and a longer heating portion 22 can be arranged in a limited space. On the other hand, the reciprocating distance of the heating portion 22 can be gradually reduced from the center to the periphery, ensuring that there is sufficient protective spacing between the heating portion 22 and the edge of the heating surface 12 to prevent the heating portion 22 from being too close.

[0045] In some embodiments, the heating element 20 may further be provided with a plurality of pins 23, which are arranged at intervals along the periphery of the heating portion 22. The pins 23 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 23 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.

[0046] In some embodiments, the heating portion 22 is provided with a plurality of cutouts 221, which are spaced apart along the extension direction of the heating portion 22. Thus, two parallel heating circuits can be formed on either side of the cutouts 221, and the positions before and after the cutouts 221 form connection points 222 of the two heating circuits. On the one hand, the connection points 222 can increase the strength of the heating portion 22 and prevent deformation of the heating portion 22. On the other hand, the connection points 222 can divide the entire wide heating portion 22 into multiple heating lines, avoiding the formation of localized high-temperature hot spots within the heating portion 22, thereby ensuring a more uniform temperature when the heating element 20 is heated.

[0047] In some embodiments, the heating surface 12 is provided with a mounting boss 121, which extends from the mounting opening 321. The heating element 20 is disposed on the surface of the mounting boss 121, and the end wall portion 32 is flush with the surface of the mounting boss 121, or the surface of the mounting boss 121 protrudes from the end wall portion 32. The mating relationship between the mounting boss 121 and the mounting opening 321 can further increase the contact area between the rigid body 30 and the porous body 10, thereby improving the stability of the two after assembly. The mounting boss 121 and the mounting opening 321 also help reduce the alignment error between the porous body 10 and the rigid body 30, and the coaxiality and installation accuracy after assembly.

[0048] In some embodiments, please refer to Figure 4 The edge of the mounting opening 321 is spaced from the outer peripheral side of the mounting boss 121 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 121 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 121, thereby effectively preventing the porous body 10 from breaking and improving the manufacturing yield and reliability of the heating component 100.

[0049] In some embodiments, a limiting protrusion 44 is provided on the outer peripheral side of the pot body 40, and the side wall portion 31 abuts against the limiting protrusion 44. By providing the limiting protrusion 44, when the rigid body 30 is installed into the first end 42 of the pot body 40, the limiting protrusion 44 and the side wall portion 31 of the rigid body 30 can be abutted against each other to control the assembly stroke of the rigid body 30, thereby controlling the compression amount of the flexible body 50, preventing the flexible body 50 from being over-compressed and causing the porous body 10 to be subjected to excessive extrusion force and cracking, thereby ensuring that the heating assembly 100 has good sealing and reliability.

[0050] In some embodiments, the inner wall surface of the accommodating chamber 41 near the first end 42 is provided with a guide slope 411, and the guide slope 411 is inclined toward the lower oil opening 421. By utilizing the guiding 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 421.

[0051] In some embodiments, at least a portion of the outer peripheral side surface of the first end 42 of the pot body 40 is tilted toward the flow guide slope 411, so that an escape space (not shown) is formed between the outer peripheral side surface of the first end 42 and the rigid body 30, and the flexible body 50 is accommodated in the escape space. By tilting the first end 42 of the pot body 40 toward the flow guide slope 411, sufficient escape space is provided for the flexible body 50, thereby accommodating the flexible body 50 therein, making the entire heating assembly 100 more compact and improving the performance of the flexible body 50. Furthermore, the problem of excessively thickened wall surface of the first end 42 of the pot body 40, which would otherwise result from the flow guide slope 411 being tilted toward the lower oil opening 421, is avoided. By tilting the outer peripheral side surface of the first end 42 toward the flow guide slope 411, the first end 42 is ensured to have a substantially uniform wall thickness, ensuring that heat can be quickly transferred to the inner wall surface of the accommodating cavity 41.

[0052] A first step 422 is provided on the outer side of the first end 42 of the pot body 40 within the clearance space. The flexible body 50 is provided with a second step 51 corresponding to the first step 422. When the flexible body 50 is installed in the space, the first step 422 and the second step 51 are mated and connected. This mating relationship between the first step 422 and the second step 51 not only improves the strength and stability of the connection between the flexible body 50 and the pot body 40, thereby enhancing the sealing effect, but also serves as a position limiter for the flexible body 50, preventing it from moving along the axial direction z of the pot body 40 and improving assembly stability.

[0053] 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.
