[0042] Refer to Figure 2 and Figure 3 As shown, the atomization assembly 10 involved in the embodiment of the present application includes a heating element 100 and an electrical connection assembly 200.

[0043] Specifically, the heating element 100 is cylindrical and made of electrically conductive dense ceramic. An atomization channel 110 extending along the axial direction of the heating element 100 is provided inside the heating element 100, and a plurality of spaced liquid guide holes 120 are also penetratingly formed on the side wall of the heating element 100. Each liquid guide hole 120 is arrayed around the atomization channel 110 and communicated with the atomization channel 110. For example, the liquid guide holes 120 are evenly distributed along the circumferential direction of the atomization channel 110; the electrical connection assembly 200 includes two spaced electrical connectors 210, and both of the two electrical connectors 210 are electrically connected to the heating element 100.

[0044] In the above atomization assembly 10, since both of the two spaced electrical connectors 210 of the electrical connection assembly 200 are electrically connected to the heating element 100, the heating element 100 can be energized and heated through the electrical connection assembly 200. Also, since an atomization channel 110 extending along the axial direction of the heating element 100 is provided inside the heating element 100, and a plurality of spaced liquid guide holes 120 are also penetratingly formed on the side wall of the heating element 100, the atomization matrix can enter the atomization channel 110 through the plurality of liquid guide holes 120, so as to heat the small amount of atomization matrix in the liquid guide holes 120 and the atomization matrix entering the atomization channel 110 from the liquid guide holes 120 through the heating of the heating element 100, so as to realize the atomization of the atomization matrix. Since there are many liquid guide holes 120, the atomization matrix can contact the heating element 100 through the inner walls of the numerous liquid guide holes 120 and also through the inner side wall of the heating element 100. Therefore, the atomization surface area of the heating element 100 is large, and the amount of smoke generated by atomization can be ensured. Since the heating element 100 is made of dense ceramic instead of porous ceramic made by adding pore-forming agents, the heating element 100 itself has fewer defects such as pores or cracks. Thus, the structural stability and firmness of the heating element 100 can be improved. When forming the liquid guide holes 120 on the heating element 100, powder falling is not likely to occur, and at the same time, the damage to the heating element 100 can be reduced. Also, when assembling the above atomization assembly 10, the phenomenon of breakage and failure of the heating element 100 can be reduced, which not only improves the assembly efficiency but also reduces the material cost.

[0045] Specifically, continuing to refer to Figure 2 and Figure 3 As shown, in some embodiments, the heating element 100 has a first end 150 and a second end 160 along the axial direction. The connection position of one electrical connector 210 and the heating element 100 is set at the first end 150, and the connection position of the other electrical connector 210 and the heating element 100 extends from the first end 150 to the second end 160, so that all parts of the heating element 100 along the axial direction can be energized with the electrical connection assembly 200, and further all parts of the heating element 100 along the axial direction can generate heat.

[0046] Reference Figure 4 as well as Figure 6 As shown, in some embodiments, the heating body 100 includes a heating body portion 130, the heating body portion 130 is provided with an atomization channel 110 and a plurality of liquid guide holes 120, and a plurality of protrusions 140 are formed on the inner wall of the heating body portion 130, the plurality of protrusions 140 are arranged along the circumference of the heating body portion 130, and each protrusion 140 extends along the axial direction of the heating body portion 130.

[0047] Specifically, in some embodiments, both of the two electrical connectors 210 are electrically connected to the heat generating body 130 .

[0048] In this embodiment, the heating body 130 can generate heat by energizing, so that the atomizing matrix entering the atomizing channel 110 can be heated to achieve atomization of the atomizing matrix. In the process of atomizing the atomizing matrix, the atomizing matrix is atomized by contacting the atomizing matrix with the inner wall of the heating body 130. Since the inner wall of the heating body 130 is formed with a plurality of protrusions 140, the contact between the atomizing matrix and the inner wall of the heating body 130 can be increased by the plurality of protrusions 140. The contact area is increased so that the atomized matrix can be atomized more fully. Furthermore, since the plurality of protrusions 140 are arranged along the circumference of the heating main body 130, and each protrusion 140 extends along the axial direction of the heating main body 130, the protrusions 140 can be formed at various locations on the inner wall of the heating main body 130, so that the atomized matrix entering the atomization channel 110 from each liquid guide hole 120 can fully contact the inner wall of the heating main body 130, thereby improving the atomization adequacy of the atomized matrix. In addition, the method of forming the strip-shaped protrusions 140 on the inner wall of the heating main body 130 can facilitate processing. For example, the heating main body 130 and the protrusions 140 can be integrally sintered and formed by a mold without complicated processes.

[0049] In some embodiments, the cross-sectional shape of each protrusion 140 along the radial direction of the heating element 100 is tooth-shaped, semicircular, semi-elliptical or trapezoidal;

[0050] and / or reference Figure 7 As shown, the thickness L1 of each protrusion 140 along the radial direction of the heat generating element 100 satisfies: 50 μm≤L1≤500 μm.

[0051] Specifically, refer to Figure 6 as well as Figure 7 As shown, in this embodiment, the cross-sectional shape of each protrusion 140 along the radial direction of the heating element 100 is a tooth shape.

[0052] Specifically, L1 can be 50μm, 100μm, 200μm, 300μm, 400μm, 500μm, etc.

[0053] In this embodiment, when the cross-sectional shape of each convex portion 140 along the radial direction of the heating element 100 is tooth-shaped, semi-circular, semi-elliptical or trapezoidal, the contact area between the atomization matrix and the inner wall of the heating main body portion 130 can be increased through the convex portion 140, so that the atomization matrix can be atomized more fully. If the thickness L1 of each convex portion 140 along the radial direction of the heating element 100 satisfies: L1 < 50 μm, the thickness of the convex portion 140 protruding from the heating main body portion 130 along the radial direction of the heating element 100 will be too small, further weakening the effect of increasing the contact area between the convex portion 140 and the inner wall of the heating main body portion 130 on the atomization matrix, so that the atomization effect of the atomization matrix is weakened. If the thickness L1 of each convex portion 140 along the radial direction of the heating element 100 satisfies: L1 > 500 μm, the thickness of the convex portion 140 protruding from the heating main body portion 130 along the radial direction of the heating element 100 will be too large, and when polishing the convex portion 140, the processing difficulty of the convex portion 140 will be increased. When the thickness L1 of each convex portion 140 along the radial direction of the heating element 100 satisfies: 50 μm ≤ L1 ≤ 500 μm, both the atomization effect of the atomization matrix can be ensured and the processing difficulty of the convex portion 140 can be reduced.

[0054] Refer to Figure 5 As shown, in some embodiments, the wall thickness of the heating element 100 is L2, satisfying: 0.1 mm ≤ L2 ≤ 0.7 mm.

[0055] Specifically, L2 can take 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, etc.

[0056] In this embodiment, if the wall thickness L2 of the heating element 100 satisfies: L2 < 0.1 mm, the wall thickness of the heating element 100 will be too thin, resulting in a reduction in the structural strength of the heating element 100, and it is not convenient to provide a plurality of liquid guide holes 120 on the side wall of the heating element 100, and collapse or fragmentation is likely to occur. At the same time, the connection difficulty between the heating element 100 and the electrical connection member 210 will also be increased. If the wall thickness L2 of the heating element 100 satisfies: L2 > 0.7 mm, the wall thickness of the heating element 100 will be too thick, resulting in too long an energized heating time of the heating element 100, further resulting in too long a heating time of the atomization matrix, and reducing the atomization effect of the atomization matrix. When the wall thickness L2 of the heating element 100 satisfies: 0.1 mm ≤ L2 ≤ 0.7 mm, both the structural strength of the heating element 100 and the atomization effect on the atomization matrix can be ensured.

[0057] Refer to Figure 4As shown, in some embodiments, the aperture diameter of the liquid guiding hole 120 is D1, and the distance between any two adjacent liquid guiding holes 120 is L3, satisfying: 0.01 mm ≤ D1 ≤ 0.15 mm, and / or, 0.1 mm ≤ L3 ≤ 1.2 mm.

[0058] Specifically, D1 can take values such as 0.01 mm, 0.05 mm, 0.10 mm, 0.15 mm, etc.; L3 can take values such as 0.1 mm, 0.4 mm, 0.8 mm, 1.2 mm.

[0059] In this embodiment, if the aperture diameter D1 of the liquid guiding hole 120 satisfies: D1 < 0.01 mm, it will make the aperture diameter of the liquid guiding hole 120 too small, resulting in excessive difficulty in drilling, and the too small aperture diameter of the liquid guiding hole 120 will slow down the speed of the atomization matrix entering the atomization channel 110, then the atomization matrix will block the liquid guiding hole 120, and further the atomization matrix will appear charring phenomenon in the liquid guiding hole 120. If the aperture diameter D1 of the liquid guiding hole 120 satisfies: D1 > 0.15 mm, it will make the aperture diameter of the liquid guiding hole 120 too large, further reducing the structural strength of the heating element 100, and prone to collapse or fragmentation. At the same time, the too large aperture diameter of the liquid guiding hole 120 will cause liquid leakage, affecting the suction taste. When the aperture diameter D1 of the liquid guiding hole 120 satisfies: 0.01 mm ≤ D1 ≤ 0.15 mm, it can not only improve the user experience, but also improve the structural strength of the heating element 100; if the distance L3 between any two adjacent liquid guiding holes 120 satisfies: L3 < 0.1 mm, it will make the distance between any two adjacent liquid guiding holes 120 too small, thus increasing the difficulty of creating the liquid guiding hole 120 and prone to collapse or fragmentation. If the distance L3 between any two adjacent liquid guiding holes 120 satisfies: L3 > 1.2 mm, it will make the distance between any two adjacent liquid guiding holes 120 too large, resulting in a decrease in the number of liquid guiding holes 120, and further reducing the concentration of the atomization matrix entering the atomization channel 110 through the liquid guiding holes 120, affecting the user's suction taste. When the distance L3 between any two adjacent liquid guiding holes 120 satisfies: 0.1 mm ≤ L3 ≤ 1.2 mm, it can not only reduce the difficulty of creating the liquid guiding hole 120, but also improve the user's suction taste.

[0060] Specifically, in some embodiments, the aperture diameters of each liquid guiding hole 120 can be equal or not equal. The aperture diameter of the liquid guiding hole 120 is determined according to the heating degree at different positions of the heating element 100. The aperture diameter of the liquid guiding hole 120 opened at the position with a higher heating degree is larger, and the aperture diameter of the liquid guiding hole 120 opened at the position with a lower heating degree is smaller, so as to avoid charring phenomenon and improve the atomization effect at the same time.

[0061] Refer to Figure 1As shown, in some embodiments, the atomization component 10 further includes a liquid storage member 300. The liquid storage member 300 surrounds the periphery of the heating element 100, and the liquid storage member 300 at least partially covers the liquid guiding holes 120.

[0062] It can be understood that the atomization matrix can be stored in the liquid storage member 300. Since the liquid storage member 300 surrounds the periphery of the heating element 100 and the liquid storage member 300 at least partially covers the liquid guiding holes 120, the atomization matrix in the liquid storage member 300 can enter the atomization channel 110 through the plurality of liquid guiding holes 120, so as to heat the atomization matrix entering the atomization channel 110 by the heating of the heating element 100, thereby realizing the atomization of the atomization matrix.

[0063] Specifically, in some embodiments, the liquid storage member 300 is at least one of fiber cotton, non-woven fabric, linen, special fiber and porous ceramic, and the liquid storage member 300 is arranged in contact with the outer wall of the heating element 100.

[0064] In this embodiment, fiber cotton, non-woven fabric, linen, special fiber and porous ceramic are all porous materials. The porous materials are convenient for storing the atomization matrix, reducing the risk of liquid leakage. At the same time, the porous materials are also beneficial for the atomization matrix to enter the liquid guiding holes 120 from the liquid storage member 300.

[0065] Specifically, in some other embodiments, the liquid storage member 300 is a porous ceramic, and the liquid storage member 300 is integrally formed by sintering with at least one of the heating element 100 and the electrical connection component 200.

[0066] More specifically, in one embodiment, the electrical connection component 200 is vacuum welded to the heating element 100, and the heating element 100 and the porous ceramic are integrally formed by sintering. In another embodiment, the electrical connection component 200 and the heating element 100 are integrally formed by sintering, and the porous ceramic is sleeved on the heating element 100. In still another embodiment, the liquid storage member 300, the heating element 100 and the electrical connection component 200 are integrally formed by sintering.

[0067] In this embodiment, since the liquid storage member 300 is a porous ceramic, the liquid storage member 300 has the advantage of being able to be integrally formed by sintering with the heating element 100, so as to improve the structural strength of the atomization component 10, reduce the liquid leakage risk of the atomization component 10, and reduce the assembly difficulty of the atomization component 10.

[0068] Specifically, in some embodiments, the heating element 100 is made of multiple materials by sintering. The multiple materials include a main material and a conductive phase. The main material is at least one of silicon carbide and silicon nitride, and the conductive phase is a conductive boride.

[0069] More specifically, in some embodiments, the conductive boride can be titanium diboride, zirconium diboride, etc.

[0070] In this embodiment, the heating element 100 is sintered from silicon carbide and titanium diboride, or from silicon carbide and zirconium diboride, or from silicon nitride and titanium diboride, or the heating element 100 is sintered from silicon nitride and zirconium diboride.

[0071] In some embodiments, the multiple materials further include an auxiliary phase, and the auxiliary phase is boron nitride.

[0072] In this embodiment, the auxiliary phase is used to increase the toughness and structural strength of the heating element 100 and plays an auxiliary role in the sintering and forming process of the heating element 100. Thus, the heating element 100 can also be sintered from silicon carbide, titanium diboride, and boron nitride, or from silicon carbide, zirconium diboride, and boron nitride, or from silicon nitride, titanium diboride, and boron nitride, or from silicon nitride, zirconium diboride, and boron nitride.

[0073] In some embodiments, during the sintering process of the heating element 100, at least one of a titanium source and a carbon source is introduced for reaction sintering to improve the structural strength of the heating element 100 after sintering and forming.

[0074] Refer to Figure 8 As shown, the embodiment of the present application further relates to an atomizing device, including: a device main body 20 and the above-mentioned atomizing assembly 10.

[0075] Specifically, the device main body 20 is provided with an air passage 21; the atomizing assembly 10 is arranged in the air passage 21, and the atomizing channel 110 of the atomizing assembly 10 is communicated with the air passage 21.

[0076] In the above atomizing device, since the atomizing assembly 10 is arranged in the air passage 21 and the atomizing channel of the atomizing assembly 10 is communicated with the air passage 21, after the atomizing matrix is atomized in the atomizing assembly 10, it can enter the user's oral cavity through the air passage 21 to realize the user's suction process. Since the above atomizing assembly 10 has strong structural stability, the product yield rate of the above atomizing device during the assembly process can be improved.
