[0037] This application provides an atomization assembly. Figure 1-Figure 4, the atomization assembly 100 may include an oil cup 10, an oil guide bracket 20, an atomization bracket 30 and an atomization core 40. A suction nozzle 11 is provided at one end of the oil cup 10, and the atomization bracket 30 is installed in the oil cup 10 at one end away from the suction nozzle 11. The oil guide bracket 20 is covered on the atomization bracket 30 and encloses an atomization chamber 31 with the atomization bracket 30, and the atomization core 40 is installed in the atomization chamber 31. The atomization chamber 31 is connected to the suction nozzle 11, thereby forming an air intake channel from the atomization bracket 30, the atomization chamber 31, and the oil guide bracket 20 to the suction nozzle 11. The oil guide bracket 20 and the oil cup 10 are surrounded to form an oil storage chamber 12 for storing the atomization matrix. An oil inlet hole 21 is opened on the oil guide bracket 20. The oil guide bracket 20 includes an oil guide portion 22, which is disposed at one end of the oil inlet hole 21 close to the atomizer core 40, and the oil guide portion 22 abuts against the atomizer core 40 to guide the atomized matrix in the oil storage chamber 12 to the atomizer core 40. The atomizer core 40 can heat the atomized matrix to produce aerosol, and the aerosol reaches the nozzle 11 through the oil guide bracket 20 and the oil cup 10.

[0038] The atomizer assembly 100 provided in the present application, the oil guide bracket 20 includes an oil guide portion 22, and the oil guide portion 22 is arranged at one end of the oil inlet hole 21 close to the atomizer core 40. The oil guide portion 22 abuts against the atomizer core 40. When the atomizer matrix in the oil storage chamber 12 flows from the oil inlet hole 21 to the atomizer core 40, the atomizer matrix can flow along the oil guide portion 22, ensuring smooth oil conduction, so that the atomizer matrix supply is stable, thereby improving the taste of the aerosol generated by atomization.

[0039] Please continue reading Figure 3 In one embodiment, the oil guide portion 22 is matched with the atomizing bracket 30 in a concave-convex manner. Specifically, a groove matching the shape of the oil guide portion 22 is formed in the atomizing bracket 30, and the oil guide portion 22 is embedded in the groove. For example, the oil guide portion 22 can also be engaged in the atomizing bracket 30 or have an interference fit with the atomizing bracket 30. During assembly, the oil guide portion 22 can be inserted into the atomizing chamber 31 to complete the installation of the oil guide bracket 20, making the installation of the oil guide bracket 20 more convenient and quick.

[0040] See also Figure 5 , Figure 6 In one embodiment, a slot 221 is provided on the oil guide portion 22, the slot 221 is connected to the oil inlet hole 21, and the atomizer core 40 is engaged in the slot 221. With such a configuration, on the one hand, the slot 221 is connected to the oil inlet hole 21, so that the atomizer matrix can flow along the oil inlet hole 21 and the inner wall of the slot 221, thereby guiding the flow direction of the atomizer matrix and ensuring smooth oil conduction; on the other hand, when the oil guide member of the atomizer core 40 is made of a flexible material such as fiber cotton, the atomizer core 40 is engaged in the slot 221, which can prevent the atomizer core 40 from shifting, further ensuring smooth oil conduction.

[0041] In one embodiment, if Figure 5As shown, at least one oil-guiding rib 211 is provided on the inner wall of the oil inlet hole 21, and the oil-guiding rib 211 extends in the direction of the oil guide portion 22 to guide the atomized matrix to the oil guide portion 22. On the one hand, the oil-guiding rib 211 can destroy the surface tension of the atomized matrix, so that the atomized matrix can smoothly enter the oil inlet hole 21; on the other hand, a drainage channel is formed between the oil-guiding rib 211 and the inner wall of the oil inlet hole 21 to guide the atomized matrix to flow to the oil guide portion 22, so that the atomized matrix is ​​supplied stably. The number of oil-guiding ribs 211 can be multiple, and multiple oil-guiding ribs 211 are distributed on the inner wall of the oil inlet hole 21 along the annular direction of the oil inlet hole 21, thereby forming multiple drainage channels, so that the atomized matrix flows evenly along the oil inlet hole 21 to the atomizing core 40.

[0042] See also Figure 3-Figure 7 In one embodiment, the atomizing bracket 30 and the oil guide bracket 20 are respectively provided with a first air inlet hole 32 and a second air inlet hole 23. The first air inlet hole 32 is in communication with the atomizing chamber 31, so that external gas can enter the atomizing chamber 31 from the first air inlet hole 32. An atomizing tube 13 is provided in the oil cup 10, one end of the atomizing tube 13 is connected to the suction nozzle, and the opposite end of the atomizing tube 13 is inserted into the oil guide bracket 20. The atomizing tube 13 is in communication with the second air inlet hole 23, and the aerosol generated in the atomizing chamber 31 can flow through the second air inlet hole 23 and the atomizing tube 13 in sequence to reach the suction nozzle 11.

[0043] The oil cup 10, the oil guide bracket 20 and the atomizer bracket 30 may be made of plastic. When the plastic materials cooperate with each other, there may be a certain gap that affects the air tightness of the atomizer assembly 100. In order to enhance the air tightness of the atomizer assembly 100, a sealing ring may be provided at the abutment between the outer wall of the oil guide bracket 20 and the atomizer bracket 30 and the inner wall of the oil cup 10. The sealing ring may be made of silicone. When the oil guide bracket 20 and the atomizer bracket 30 are assembled into the oil cup 10, the sealing ring is squeezed and elastically deformed, so that the oil guide bracket 20 and the atomizer bracket 30 are interference fit with the oil cup 10, thereby enhancing the air tightness of the atomizer assembly 100.

[0044] In one embodiment, the atomizing assembly 100 is provided with a sealing sleeve 50, such as Figure 3 As shown. The sealing sleeve 50 can be made of silicone. The sealing sleeve 50 is arranged at the connection between the atomizing tube 13 and the oil guide bracket 20, and the sealing sleeve 50 is located between the atomizing tube 13 and the oil guide bracket 20. When the oil guide bracket 20 is assembled into the oil cup 10, the atomizing tube 13 and the oil guide bracket 20 squeeze the sealing sleeve 50 to cause elastic deformation, thereby sealing the oil storage chamber 12 to prevent oil leakage.

[0045] The atomizer core 40 may include a heating element 41, an oil guide element 42, and two electrodes 43. Figure 2As shown. The oil guide 42 transfers the atomized matrix to the heating element 41, and the heating element 41 heats the atomized matrix to generate an aerosol. The electrode 43 is inserted on the atomizing bracket 30, and the electrode 43 is connected to the heating element 41. The atomizing core 40 is connected to a power source through the electrode 43, so as to provide electrical energy to the atomizing core 40.

[0046] The oil guide 42 is a porous medium. The oil guide 42 can be a porous fiber material, such as one or more of fiber cotton, non-woven fabrics, linen, chemical fiber fabrics, etc., all of which have good lipophilicity and oil-locking properties. Compared with ceramic materials, fiber materials have small pore sizes and large porosity, making the aerosol generated by atomization more delicate, with full sweetness and aroma. The material of the heating element 41 can be one of stainless steel, nickel-chromium-aluminum alloy, nickel-chromium alloy, iron-chromium-aluminum or titanium alloy, and the heating element 41 can be integrally formed by punching or etching.

[0047] The oil guide member 42 may be in the form of a sheet or a cylinder. In one embodiment, the oil guide member 42 is in the form of a hollow cylinder, and illustratively, the cross section of the oil guide member 42 may be circular or elliptical. The heating member 41 is attached to the inner wall of the oil guide member 42, or the heating member 41 is surrounded by the outer wall of the oil guide member 42. The oil guide member 42 is arranged along the longitudinal direction of the atomization assembly 100. Optionally, the number of the oil guide members 42 may be two or more.

[0048] In one embodiment, the oil guide member 42 is in the form of a sheet, and the sheet-shaped oil guide member 42 has a smaller size in the thickness direction of the atomizer assembly 100, which is conducive to the flat design of the product. Figure 8 As shown, the oil guide member 42 is clamped in the installation space 44, which can prevent the oil guide member 42 from being deformed.

[0049] The second air inlet 23 is at least partially offset from the oil guide 42 to communicate with the atomizing chamber 31, for example, 6 and Fig.17 As shown, in one embodiment, the radial dimension of the second air inlet 23 is greater than the thickness of the oil guide member 42, so that the second air inlet 23 has a portion facing the oil guide member 42 and portions located on both sides of the thickness direction of the oil guide member 42, and the aerosol can be sucked out from the portions of the second air inlet 23 located on both sides of the thickness direction of the oil guide member 42. That is, the thickness of the oil guide member 42 matches the width of the card slot 221, and the radial dimension of the second air inlet 23 is greater than the width of the card slot 221. It can be understood that the shape of the second air inlet 23 is not limited to a circle, and can also be an ellipse, a polygon, etc. In other embodiments, the second air inlet 23 can also have only a portion located on one side of the oil guide member 42 in the thickness direction.

[0050] For example, Figure 5 and Figure 6There are two oil inlet holes 21, which are distributed on both sides of the second air inlet hole 23, and each oil inlet hole 21 is provided with an oil guide portion 22. The clamping grooves 221 of the two oil guide portions 22 are arranged in a colinear manner, and the two ends of the oil guide member 42 are clamped in the two clamping grooves 221. The middle part of the oil guide member 42 at least partially blocks the second air inlet hole 23, and the second air inlet hole 23 has parts located on both sides of the oil guide member 42 in the thickness direction.

[0051] Please continue reading Figure 8 , the heating element 41 includes a heating portion 411 and two electrode portions 412. The two electrode portions 412 are respectively connected to the opposite ends of the heating portion 411, and the heating portion 411 is surrounded to form at least part of the installation space 44, and the installation space 44 has a length direction along the first direction and a width direction along the second direction. Generally speaking, the size of the installation space 44 in the first direction is larger than the size in the second direction, that is, the cross-section of the installation space 44 is wide and flat to adapt to the flattened shape of the product. At least part of the heating portion 411 is relatively arranged on both sides of the installation space 44 in the second direction, and is attached to the oil guide member 42. The oil guide member 42 transfers the atomized matrix to the heating portion 411, and the heating portion 411 heats the atomized matrix to generate an aerosol.

[0052] In one embodiment, if Figure 8 As shown, the installation space 44 is U-shaped, and the heating part 411 has a first heating surface 414 and a second heating surface 415 located on both sides of the U-shaped space, and a third heating surface 416 located on the bottom of the U-shaped space, and the electrode part 412 is arranged on the third heating surface 416. The first heating surface 414 and the second heating surface 415 are respectively at a preset angle with the third heating surface 416. Specifically, the first heating surface 414 and the second heating surface 415 can be substantially perpendicular to the third heating surface 416, so that the first heating surface 414 and the second heating surface 415 are parallel to each other, so as to facilitate the clamping of the oil guide member 42. The heating part 411 is provided with multiple heating surfaces, which increases the contact area between the heating part 411 and the oil guide member 42, so that the atomized matrix can be atomized at multiple positions to generate aerosols, and the heating efficiency of the heating part 411 can be improved.

[0053] Please continue reading Figure 8In one embodiment, the heating portion 411 is formed by bending a long strip structure for multiple times to form a first heating surface 414, a second heating surface 415 and a third heating surface 416. Specifically, after the long strip structure is bent, a plurality of inverted U-shaped structures connected to each other can be formed to be arranged on the first heating surface 414 and the second heating surface 415. Among them, the third heating surface 416 is arranged at one end of the heating portion 411 facing the air inlet of the atomizing bracket 30, and the free end surfaces of the first heating surface 414 and the second heating surface 415 away from the third heating surface 416 are directed to the oil guide bracket 20. The direction in which the external air enters the atomizing chamber 31 is different from the first direction and the second direction. Optionally, the direction in which the external air enters the atomizing chamber 31 can be perpendicular to the third heating surface 416. Accordingly, the first heating surface 414 and the second heating surface 415 are parallel to the air inlet direction, so that the aerosol produced by atomization can smoothly reach the suction nozzle 11 along the first heating surface 414 and the second heating surface 415.

[0054] In one embodiment, if Fig. 9 As shown, the heating portion 411 includes at least two heating units 417 and a reinforcement portion 418. The heating units 417 are arranged in a first direction at intervals. The heating units 417 are at least partially located on the first heating surface 414 and the second heating surface 415. Two adjacent heating units 417 are connected by a reinforcement portion 418 disposed on the third heating surface 416. The heating element 41 provided in the present application, the heating portion 411 includes at least two heating units 417 and a reinforcement portion 418. Two adjacent heating units 417 are connected by the reinforcement portion 418. Compared with the heating portion 411 formed by bending a single wire, the reinforcement portion 418 is disposed between two adjacent heating units 417 to improve the integrity of the heating portion 411 and prevent the heating portion 411 from being deformed during the assembly process, thereby ensuring the taste of the product.

[0055] The reinforcement portion 418 may be in the form of a sheet, see Fig.11 . The dimension of the reinforcing portion 418 in the second direction (the Y direction shown in the figure) is D1, and the dimension of the third heating surface 416 in the second direction is D2. In some embodiments, D1 / D2≥0.5. Studies have found that if D1 / D2 is less than 0.5, the bending rigidity of the heating portion 411 is limitedly improved, and there is a risk of deformation when the heating portion 411 is squeezed during the assembly process. Optionally, D1 / D2 can be 0.5, 0.6, 0.7, 0.8, 0.9, etc., which are not specifically limited here. By setting D1 / D2≥0.5, the reinforcing portion 418 has a larger cross-sectional area, which improves the strength of the heating portion 411, and can further prevent the heating portion 411 from deforming during the assembly process, thereby ensuring the taste of the product.

[0056] In one embodiment, if Fig.12, the dimension of the reinforcing portion 418 in the second direction is equal to the dimension of the third heating surface 416 in the second direction. That is, D1 / D2 is 1.0, and the reinforcing portion 418 is equal in width to the third heating surface 416, which facilitates the processing of the heating element 41.

[0057] Please continue reading Fig. 9 and Fig.10 In one embodiment, the heating unit 417 includes a curved first heating segment 4171 and a second heating segment 4172, each of which is arranged at intervals on the first heating surface 414, and each of which is arranged at intervals on the second heating surface 415. Each of the curved first heating segment 4171 and the second heating segment 4172 has two free ends away from the bent end. Among them, the free end of the first heating segment 4171 and the free end of the second heating segment 4172 of each heating unit 417 are connected to the adjacent free end of the first heating segment 4171 and the adjacent free end of the second heating segment 4172 of the adjacent heating unit 417 through a reinforcing portion 418. The two free ends of the first heating segment 4171 and the two free ends of the second heating segment 4172 of the heating unit 417 located at the upper end in the first direction are respectively connected to the reinforcing portion 418 and the electrode portion 412.

[0058] For the heating part 411 formed by bending a single wire, the heating wire has an equal cross-section, so the resistivity of the heating wire on each heating surface is equal, and the heating temperature is roughly the same, while the third heating surface 416 is relatively far from the oil storage chamber 12, and it is easy to have insufficient supply of atomized matrix, which makes the aerosol produce a sticky smell. In the present application, the first heating section 4171 and the second heating section 4172 are connected in parallel on opposite sides of the reinforcement part 418, and the cross-sectional area of ​​the reinforcement part 418 is significantly larger than the cross-sectional area of ​​the first heating section 4171 and the second heating section 4172, so the resistance of the reinforcement part 418 is much smaller than the resistance of the first heating section 4171 and the second heating section 4172, so that the heating power of the heating part 411 is concentrated on the first heating surface 414 and the second heating surface 415, and the temperature of the third heating surface 416 is relatively low, and the atomized matrix cannot be atomized on the third heating surface 416 to produce aerosol, which can avoid the aerosol from producing a sticky smell.

[0059] In one embodiment, the first heating segment 4171 and the second heating segment 4172 are both U-shaped or V-shaped. Such a configuration makes the first heating segment 4171 and the second heating segment 4172 relatively slender, which can increase the resistance of the heating segment, so that the heating power of the heating part 411 is concentrated on the first heating surface 414 and the second heating surface 415.

[0060] Please continue reading Fig.11. The dimension of the reinforcement part 418 in the first direction (the X direction shown in the figure) is L1; the distance between the outer edges of the free ends of two adjacent first heating segments 4171 is L2, and / or the distance between the outer edges of the free ends of two adjacent second heating segments 4172 is L2. In some embodiments, L1 / L2≥0.9. Studies have shown that if L1 / L2 is less than 0.9, the cross-section of the reinforcement part 418 is small, the bending stiffness is relatively small, the bending stiffness of the heating part 411 is improved to a limited extent, and the heating part 411 is at risk of deformation when squeezed during the assembly process; in addition, the resistance of the reinforcement part 418 is large, and the reinforcement part 418 is connected in series with the heating unit 417 in the circuit, so that the reinforcement part 418 has a large heating power, and the atomized matrix is ​​easily atomized in the reinforcement part 418 located on the third heating surface 416, and a burnt smell is generated due to insufficient supply of the atomized matrix. Optionally, L1 / L2 can be 0.9, 0.95, 1.0, 1.05, 1.1, etc., which are not specifically limited here. By setting L1 / L2≥0.9, the reinforcing portion 418 has a larger cross-sectional area. On the one hand, the strength of the heating portion 411 is improved, which can further prevent the heating portion 411 from deforming during the assembly process and ensure the taste of the product; on the other hand, the resistance and heating power of the reinforcing portion 418 are reduced, and the atomized matrix cannot be atomized on the third heating surface 416 to produce aerosol, which can avoid the aerosol from producing a burnt taste.

[0061] In one embodiment, if Fig.12 , the dimension of the reinforcing portion 418 in the first direction is equal to the distance between the free ends of the two adjacent first heating segments 4171 and the free ends of the second heating segment 4172. That is, L1 / L2 is 1.0, and the outer edge of the reinforcing portion 418 is flush with the free ends of the two adjacent first heating segments 4171 and the free ends of the second heating segment 4172, which can facilitate the processing of the heating element 41.

[0062] In one embodiment, the first heating segment 4171 on the first heating surface 414 and the corresponding second heating segment 4172 on the second heating surface 415 are symmetrically arranged. Fig.11 , Fig.12 As the first heating section 4171 and the second heating section 4172 are symmetrically arranged, the heating temperatures of the first heating surface 414 and the second heating surface 415 are substantially the same, and the atomized matrix can be atomized on the first heating surface 414 and the second heating surface 415 to produce aerosol, thereby ensuring consistency of taste.

[0063] Please continue reading Figure 8In one embodiment, the heating element 41 also includes a reinforcement 413, and the reinforcement 413 is connected to the electrode portion 412. The heating portion 411, the electrode portion 412 and the reinforcement 413 are surrounded to form an installation space 44. The reinforcement 413 can be used to install the heating element 41. Specifically, the reinforcement 413 can be used to connect the heating element 41 to the atomization bracket 30. In order to increase the heating power of the heating portion 411, the heating portion 411 is usually a slender structure with low bending rigidity. It is easy to deform during assembly and squeeze the oil guide member 42, resulting in poor oil conduction, thereby affecting the taste of the aerosol generated by atomization. In the present application, reinforcements 413 are provided at both ends of the heating portion 411, and the bending rigidity of the reinforcement 413 can be set to be greater than the bending rigidity of the heating portion 411. The reinforcement 413 forms the skeleton of the heating element 41, which improves the integrity and bending rigidity of the heating element 41. When the heating element 41 is pressed, the reinforcing body 413 is supported on the outside of the heating portion 411 , thereby preventing the heating portion 411 from being deformed.

[0064] The reinforcement body 413 may include a first reinforcement section 4131, a second reinforcement section 4132 and a mounting section 4133. Figure 8 As shown. The first reinforcement section 4131 and the second reinforcement section 4132 are arranged on both sides of the installation space 44 in the second direction, and the installation section 4133 is connected to the first reinforcement section 4131 and the second reinforcement section 4132. Optionally, the first reinforcement section 4131 and the second reinforcement section 4132 are parallel to the first heating surface 414 and the second heating surface 415, respectively. When the heating portion 411 is squeezed, the first reinforcement section 4131 and the second reinforcement section 4132 are supported on the outside of the first heating surface 414 and the second heating surface 415, respectively, so as to prevent the heating portion 411 from being deformed.

[0065] The mounting section 4133 may be formed by bending the first reinforcement section 4131 or the second reinforcement section 4132. The mounting section 4133 may be arranged in a variety of ways. Fig.13 As shown, the mounting section 4133 is perpendicular to the first reinforcement section 4131 or the second reinforcement section 4132. When the atomizer core 40 is assembled into the atomizer chamber 31, the oil guide bracket 20 is covered on the atomizer bracket 30, and the oil guide bracket 20 presses the mounting section 4133 tightly against the upper edge of the side wall of the atomizer chamber 31, which can prevent the atomizer core 40 from shifting, thereby ensuring the consistency of the taste of the aerosol generated by atomization. Specifically, at the fitting part of the mounting section 4133, the oil guide bracket 20 and the atomizer bracket 30 can adopt the method of matching the convex and concave parts, so as to improve the reliability of the combination of the two.

[0066] In one embodiment, if Fig.14As shown, the free ends of the first reinforcement section 4131 and the second reinforcement section 4132 are respectively connected to a mounting section 4133 bent away from the mounting space 44, and the two mounting sections 4133 are respectively overlapped on opposite sides of the atomizer bracket 30. The first reinforcement section 4131 and the second reinforcement section 4132 respectively form mounting grooves 4134 with the corresponding mounting sections 4133. When the atomizer core 40 is assembled into the atomizer chamber 31, the mounting groove 4134 is buckled on the atomizer bracket 30, and a clamping force is generated between the mounting section 4133 and the first reinforcement section 4131 or the second reinforcement section 4132, thereby fixing the atomizer core 40 on the atomizer bracket 30, and preventing the atomizer core 40 from shifting.

[0067] The connection between the electrode 43 and the heating element 41 can be welded, plugged or riveted to enhance the reliability of the connection between the electrode 43 and the heating element 41. In one embodiment, the two electrodes 43 are welded to the corresponding electrode parts 412. Specifically, during the assembly process, after the atomization core 40 is assembled to the atomization chamber 31, laser welding can be used to fix the electrode 43 to prevent the electrode 43 from shifting and ensure the reliability of the connection between the electrode 43 and the heating element 41. Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It can reduce the amount of heat input to the minimum required amount, and the metallographic change range of the heat-affected zone is small, which can prevent the welding operation from affecting other components.

[0068] In one embodiment, if Figure 8 As shown, the electrode portion 412 is provided with a mounting hole 4121 , and the mounting hole 4121 is used for mounting the electrode 43 .

[0069] See also Fig.15 In one embodiment, a boss 431 is provided at one end of the electrode 43 connected to the electrode portion 412, and the cross-sectional area of ​​the boss 431 is smaller than the cross-sectional area of ​​the connection between the electrode 43 and the boss 431, thereby forming a step surface at one end of the electrode 43 close to the electrode portion 412. When the electrode 43 is assembled on the atomizer bracket 30, the boss 431 is inserted into the electrode portion 412. Specifically, the boss 431 can be inserted into the mounting hole 4121. The outer periphery of the boss 431 and the step surface at the end of the electrode 43 can both contact the electrode portion 412, thereby increasing the contact area between the electrode 43 and the electrode portion 412 and enhancing the reliability of the connection between the electrode 43 and the heating element 41.

[0070] In one embodiment, if Fig.16As shown, a rivet 432 is provided at one end of the electrode 43 connected to the electrode portion 412, and the rivet 432 passes through the electrode portion 412 to rivet the electrode 43 to the electrode portion 412. Specifically, the rivet 432 can pass through the mounting hole 4121 to rivet the electrode 43 to the electrode portion 412. By providing the rivet 432 to fix the electrode 43 to the electrode portion 412, the electrode 43 can be prevented from falling off, thereby ensuring the reliability of the connection between the electrode 43 and the heating element 41.

[0071] Please continue reading Figure 3 , the two ends of the atomizing bracket 30 have bosses 33, the two electrode parts 412 are located above the bosses 33, and the electrodes 43 pass through the bosses 33 and are connected to the electrode parts 412. Such an arrangement can reduce the size of the oil guide bracket 20 in the thickness direction of the atomizing assembly 100, which is conducive to realizing a flat design of the product.

[0072] The first air inlet 32 ​​can be arranged at the middle position of the bottom of the atomizing bracket 30, that is, the first air inlet 32 ​​is directly opposite to the middle position of the third heating surface 416 at the bottom of the heating element 41. Figure 4 As shown. At this time, the first air inlet 32 ​​and the third heating surface 416 are arranged opposite to each other, and the external air entering the atomization chamber 31 from the first air inlet 32 ​​drives the aerosol generated by the atomization of the third heating surface 416 to flow toward the suction nozzle 11. Since the first air inlet 32 ​​is arranged in the middle of the bottom of the atomization bracket 30, the space required for the first air inlet 32 ​​is relatively small, which can reduce the thickness of the atomization assembly 100 in the second direction, which is conducive to the flat design of the product. However, due to the obstruction of the third heating surface 416, the first heating surface 414 and the second heating surface 415 are not in sufficient contact with the external air, and the atomization of the atomization matrix is ​​mainly concentrated on the third heating surface 416, and the third heating surface 416 is relatively far from the oil storage chamber 12, resulting in insufficient supply of the atomization matrix, which makes the aerosol easy to produce a burnt taste.

[0073] To prevent the aerosol from having a burnt smell, in one embodiment, Fig.17 As shown, two first air inlet holes 32 are provided on the atomizing bracket 30, and the two first air inlet holes 32 are respectively arranged corresponding to the first heating surface 414 and the second heating surface 415. By providing two first air inlet holes 32, the third heating surface 416 can be prevented from being blocked, so that the first heating surface 414 and the second heating surface 415 are fully in contact with the external air, and the atomizing matrix can be fully atomized on the first heating surface 414 and the second heating surface 415 to produce aerosol, thereby improving the taste of the aerosol.

[0074] This application provides an atomization device. Fig.18, the atomizing device 300 may include the atomizing assembly 100, the control assembly 310 and the power assembly 320 as described above, and the control assembly 310 may control the atomizing assembly 100 to be connected or disconnected with the power assembly 320 according to the suction action, so as to control the atomizing assembly 100 to heat the atomizing matrix to generate aerosol or stop heating. Specifically, when inhaling through the mouthpiece 11, the control assembly 310 senses the negative pressure in the atomizing device 300, and the control assembly 310 controls the atomizing assembly 100 to be connected with the power assembly 320, and the atomizing core 40 to heat the atomizing matrix to generate aerosol; when the inhalation stops, the control assembly 310 controls the atomizing assembly 100 to be disconnected with the power assembly 320, and the atomizing core 40 stops heating the atomizing matrix.

[0075] Optionally, the atomizing assembly 100 and the power supply assembly 320 are configured to be detachable. When the remaining amount of the atomizing matrix in the atomizing assembly 100 is less than a preset value, the user can replace the atomizing assembly 100 to prevent the atomizing assembly 100 from burning dry and causing a burnt smell. Accordingly, when the atomizing device 300 is underpowered, the user can replace the power supply assembly 320 to ensure the normal use of the atomizing device 300.

[0076] The atomization assembly and atomization device provided in this application have at least the following beneficial effects:

[0077] 1. The oil guide bracket 20 includes an oil guide portion 22. The oil guide portion 22 is disposed at one end of the oil inlet hole 21 close to the atomizer core 40. The oil guide portion 22 abuts against the atomizer core 40. When the atomized matrix in the oil storage chamber 12 flows from the oil inlet hole 21 to the atomizer core 40, the atomized matrix can flow along the oil guide portion 22, ensuring smooth oil conduction and stable supply of the atomized matrix, thereby improving the taste of the aerosol generated by atomization.

[0078] 2. At least one oil guide rib 211 is provided on the inner wall of the oil inlet hole 21. On the one hand, the oil guide rib 211 can destroy the surface tension of the atomized matrix, so that the atomized matrix can smoothly enter the oil inlet hole 21; on the other hand, a drainage channel is formed between the oil guide rib 211 and the inner wall of the oil inlet hole 21 to guide the atomized matrix to flow to the oil guide part 22, so that the atomized matrix is ​​supplied stably.

[0079] 3. Reinforcements 413 are provided at both ends of the heating portion 411 to improve the integrity and bending rigidity of the heating element 41 and prevent the heating portion 411 from being deformed during assembly.

[0080] 4. The reinforcement body 413 includes a mounting section 4133 connected to the first reinforcement section 4131 and the second reinforcement section 4132 respectively, which is used to mount the heating element 41, thereby preventing the atomization core 40 from shifting, thereby ensuring the consistency of the taste of the aerosol generated by atomization.
