[0033] In order to have a more clear understanding of the technical features, purposes and effects of the utility model, the specific embodiments of the utility model will be explained in detail with reference to the drawings.

[0034] Please refer to Figure 1 and Figure 2The utility model provides an electronic atomization device, which comprises a power supply unit 6 and an atomizer. The atomizer and the power supply unit 6 are connected. The power supply unit 6 comprises a second circuit board 62 and a battery core 63. The battery core 63 and the second circuit board 62 are connected, and the battery core 63 is used for storing electric energy. The second circuit board 62 is a master control board. The second circuit board 62 is used for controlling the start (on-off) of the atomizer and controlling the charging of the battery core 63 by an external power supply. Specifically, the atomizer and the power supply unit 6 can be detachably connected together; alternatively, the atomizer and the power supply unit 6 can be an integral whole that is difficult to disassemble. The atomizer and the power supply unit 6 can form an electrical connection, and the atomizer is used for heating and atomizing an aerosol generating substrate under an energized state to generate an aerosol for a user to inhale. The aerosol generating substrate can be in a liquid, solid or paste state.

[0035] Referring to Figures 1 to 3 The utility model provides an atomizer, which comprises a shell 3, an atomizing seat 1 and an atomizing core 2 arranged in the shell 3. The atomizing core 2 and the power supply unit 6 can form an electrical connection. The atomizing core 2 is used for heating and atomizing an aerosol generating substrate under an energized state to generate an aerosol. The atomizing seat 1 is used for providing a diffusion space for the aerosol generated by the atomizing core 2 and guiding the aerosol out.

[0036] Referring to Figures 4 to 7 The atomizing seat 1 is provided with an airflow channel, which comprises an air inlet hole, an air outlet hole 103 and an atomizing cavity 102. The atomizing cavity 102 is in communication with the air inlet hole and the air outlet hole 103. That is, the air inlet hole, the atomizing cavity 102 and the air outlet hole 103 are in communication in sequence to form an airflow channel. The air inlet hole is in communication with the atmosphere, and external air can flow into the atomizing cavity 102 from the air inlet hole and then flow out of the air outlet hole 103. The atomizing cavity 102 is used for providing a diffusion space for the aerosol generated by the atomizing core 2. The atomizing core 2 is arranged on the atomizing seat 1 and is in fluid communication with the atomizing cavity 102. That is, fluid can flow between the atomizing core 2 and the atomizing cavity 102. Fluid refers to a substance that can flow continuously, including liquid, gas and aerosol. After the atomizing core 2 heats the aerosol generating substrate, the generated aerosol diffuses into the atomizing cavity 102 and mixes with the airflow in the airflow channel. The fluid formed by the mixing of the aerosol and the airflow in the airflow channel flows out of the air outlet hole 103 for a user to inhale.

[0037] The traditional atomization core 2 usually uses a single heating body 21 to heat the aerosol generating substrate, and the amount of mist is small; in order to increase the amount of mist, the heating power of the atomization core 2 can only be increased, but the heat of the heating body 21 of the resistance heating type is relatively concentrated, and when the power of the single heating body 21 is too large, the atomization core 2 is prone to burning, which produces a burnt taste and affects the user experience. In order to solve this problem, the atomization core 2 of the utility model comprises at least two heating bodies 21, and adjacent heating bodies 21 are arranged at the periphery of the air outlet hole 103. That is, the number of heating bodies 21 can be two, three, four, etc. Each heating body 21 will heat up in the powered state, and the aerosol generating substrate will be heated and atomized after contacting the heating body 21 in the heating state, thereby generating aerosol. By arranging at least two heating bodies 21 to heat the aerosol generating substrate, the power of the single heating body 21 will not be too large, but the sum (total power) of the powers of the heating bodies 21 can be increased, so that the atomization core 2 heats evenly, and the amount of mist is increased and the risk of burning of the atomization core 2 is reduced.

[0038] Furthermore, the atomization cavity 102 is provided with a flow guide structure 5, and the flow guide structure 5 is arranged towards the air outlet hole 103. Specifically, the flow guide structure 5 can be arranged directly below the air outlet hole 103, that is, the projections of the flow guide structure 5 and the air outlet hole 103 in the vertical direction at least partially overlap. The vertical direction can refer to the V-V direction in Figure 5 . The flow guide structure 5 is used to change the flow direction of the aerosol in the atomization cavity 102 and to accelerate the flow speed of the aerosol, so as to quickly guide the mixed fluid of the aerosol and air out of the air outlet hole 103, thereby increasing the mist output rate. Due to the increase in the mist output rate, the rate of loss of aerosol temperature and taste is reduced.

[0039] In summary, since the atomization core 2 comprises at least two heating bodies 21, and the at least two heating bodies 21 heat the aerosol generating substrate respectively, the atomization core 2 can heat evenly, the amount of mist can be increased, and the risk of burning of the atomization core 2 can be reduced; since the atomization cavity 102 is provided with the flow guide structure 5 which is arranged opposite to the air outlet hole 103, the flow guide structure 5 is used to change the flow direction of the aerosol in the atomization cavity 102 and to accelerate the flow speed of the aerosol, so as to quickly guide the mixed fluid of the aerosol and air out of the air outlet hole 103, thereby increasing the mist output rate and reducing the rate of loss of aerosol temperature and taste. Due to the increase in the amount of mist and the mist output rate, the amount of smoke per puff of the user is effectively increased, and the aerosol has a good taste, thereby improving the user experience.

[0040] As shown in Figure 5 and Figure 7 , in some embodiments, the at least two heating bodies 21 are arranged at opposite sides of the flow guide structure 5. For example Figure 5In the illustrated embodiment, the two heat-generating bodies 21 are respectively located on the two opposite sides in the transverse direction of the flow guide structure 5, which can be referred to as the C-C direction in the figure. Figure 5 That is, the two heat-generating bodies 21 are respectively located on the left side and the right side in the transverse direction of the flow guide structure 5. When there are more than two heat-generating bodies 21, any two of them can be located on the opposite sides in the transverse direction of the flow guide structure 5. In this way, the mist directions of the respective heat-generating bodies 21 relative to the flow guide structure 5 are different, which is conducive to the full mixing of the aerosol and the air in the atomization cavity 102 and the consistent taste of the aerosol. The flow guide structure concentrates the aerosol (mist) from different directions to the position of the air outlet hole 103.

[0041] As shown in Figure 5 some embodiments, the atomization seat 1 is provided with at least two through holes 14 communicating with the atomization cavity 102, and the through holes 14 and the heat-generating bodies 21 correspond one-to-one, and the atomization core 2 is in fluid communication with the atomization cavity 102 through the through holes 14. That is, the number of through holes 14 is consistent with the number of heat-generating bodies 21, and each heat-generating body 21 is arranged at a through hole 14 and exposed to the atomization cavity 102 through the through hole 14. Thus, the aerosol generated at the heat-generating body 21 can diffuse into the atomization cavity 102. Specifically, as shown in the Figure 6 and Figure 7 embodiments, there are two through holes 14 and two heat-generating bodies 21, and the two through holes 14 are arranged on the opposite sides of the periphery of the air outlet hole 103, so that the heat-generating bodies 21 are arranged on the opposite sides of the periphery of the air outlet hole 103. Of course, in other embodiments, the respective through holes 14 can be arranged on the periphery of the air outlet hole 103 at intervals along the circumference of the air outlet hole 103; or the respective through holes 14 can be asymmetrically arranged on the outside of the air outlet hole 103.

[0042] Specifically, as shown in Figures 5 to 7 some embodiments, the atomization seat 1 includes a base 11 and a bracket 12, and the base 11 and the bracket 12 are mounted together to jointly enclose the atomization cavity 102. The atomization core 2 is arranged on the bracket 12. The flow guide structure 5 is formed on the surface of the base 11 facing the atomization core 2. Further, the through holes 14 are also formed on the bracket 12. The atomization core 2 can be mounted to the bracket 12 from the side of the bracket 12 away from the base 11. The base 11 can be an elastic member, such as a material of silicone, rubber, silicone rubber, etc.

[0043] As shown in Figures 5 to 8As shown, in some embodiments, the base 11 is provided with a first mounting hole 101, which penetrates through the surface of the base 11 facing the atomization core 2 and the surface of the base 11 facing away from the atomization core 2. The first mounting hole 101 can serve as an air inlet hole for communicating the atomization cavity 102. Alternatively, in other embodiments, the air inlet hole can also be provided at other positions on the base 11. Specifically, the base 11 comprises a ring-shaped side wall 111 and a bottom wall 112 connected to each other. The bottom wall 112 extends in the transverse direction. The flow guide structure 5 is formed on the surface of the bottom wall 112 facing the atomization core 2.

[0044] The atomizer further comprises a first circuit board 61 for connecting the power supply unit 6. The first circuit board 61 is arranged on the side of the base 11 facing away from the atomization core 2. Specifically, the first circuit board 61 is arranged on the surface of the base 11 facing away from the bracket 12. As shown Figure 2 and Figure 3 As shown, the battery core 63 and the second circuit board 62 are arranged on the side of the first circuit board 61 away from the base 11. Moreover, the battery core 63 is located between the first circuit board 61 and the second circuit board 62. On the one hand, the first circuit board 61 and the second circuit board 62 are connected; on the other hand, the first circuit board 61 is provided with a plurality of conductive columns 611, which are connected to the heating body 21 after penetrating through the first mounting hole 101 upwardly. That is, the first circuit board 61 is connected to the heating body 21 through the conductive columns 611. The second circuit board 62 can serve as a master control board for controlling the operation of the heating body 21, while the first circuit board 61 serves as a connection medium between the heating body 21 and the second circuit board 62.

[0045] Specifically, the conductive column 611 abuts against the heating body 21 at the end thereof away from the first circuit board 61. Corresponding to at least two heating bodies 21, the number of conductive columns 611 is at least three, and each two conductive columns 611 serve as a positive electrode and a negative electrode, respectively. As shown Figure 6 In the embodiment shown, there are four conductive columns 611 in total, two of which are connected to one of the heating bodies 21, and the other two are connected to the other heating body 21. Alternatively, one of the conductive columns 611 can also be connected to both of the heating bodies 21 simultaneously, serving as a common electrode for the two heating bodies 21.

[0046] As shown Figures 5 to 7 In some embodiments, the airflow passage further comprises a gas guide hole 64 arranged on the first circuit board 61. The gas guide hole 64 penetrates through the first circuit board 61 in the thickness direction of the first circuit board 61. The gas guide hole 64 is in communication with the air inlet hole (e.g., the first mounting hole 101). The air in the external atmospheric environment of the atomizer enters the atomization cavity 102 through the gas guide hole 64 and the air inlet hole (e.g., the first mounting hole 101) in sequence, and carries the aerosol in the atomization cavity 102 out through the air outlet hole 103.

[0047] As shownFigures 5 to 7 As shown, in some embodiments, the support 12 includes a connected body 122 and a support leg 121. The atomizing core 2 is disposed on the body 122. Specifically, the body 122 is generally a frame structure, including a platform extending laterally and a sidewall extending vertically. The support leg 121 is connected to the sidewall. The atomizing core 2 is disposed on the platform extending laterally. The support leg 121 is at least partially located on the side of the base 11 opposite to the atomizing core 2. Specifically, the support leg 121 is at least partially located on the side of the bottom wall 112 of the base 11 opposite to the atomizing core 2. That is, the support leg 121 may be partially or entirely located on the side of the bottom wall 112 opposite to the atomizing core 2. A first circuit board 61 abuts against the support leg 121. Specifically, the support leg 121 is generally L-shaped, with a step extending laterally formed at the end away from the sidewall of the body 122, and the edge of the first circuit board 61 abuts against the step. Thus, the first circuit board 61 is fixed to the side of the base 11 facing away from the atomizing core 2 by the support leg 121.

[0048] like Figures 5 to 7 In the illustrated embodiment, the bracket 12 includes two legs 121 disposed on the lateral sides of the sidewall of the main body 122. Two first mounting holes 101 are provided on the base 11, located on opposite lateral sides of the flow guide structure 5. The two legs 121 correspond one-to-one with the two first mounting holes 101. When the bracket 12 is inserted into the base 11, each leg 121 passes through the first mounting hole 101 and reaches the side of the base 11 facing away from the atomizing core 2. Specifically, each leg 121 passes through the first mounting hole 101 and reaches the bottom wall 112 of the base 11 facing away from the atomizing core 2. Simultaneously, the main body 122 of the bracket 12 can rest against and be supported on the bottom wall 112 of the base 11.

[0049] like Figure 6 As shown, in some embodiments, the main body 122 is provided with a plurality of through holes 123 corresponding one-to-one with the conductive posts 611. That is, the number of through holes 123 is equal to the number of conductive posts 611. Each conductive post 611 corresponds to one through hole 123. The conductive post 611 passes through the first mounting hole 101 and the through hole 123 in sequence and is connected to the heating element 21. Specifically, the through holes 123 are formed on the laterally extending platform of the main body 122. The through hole 14 is also formed on the laterally extending platform of the main body 122, and the through holes 123 are located outside the through holes 14. Further, as Figures 5 to 7As shown, in some embodiments, the atomization seat 1 further comprises a top cover 13, which is arranged on the side of the bracket 12 away from the base 11, and the bracket 12 and the top cover 13 are connected, and the atomization core 2 is clamped and fixed between the bracket 12 and the top cover 13. In this way, the atomization core 2 can be clamped and fixed by the cooperation of the bracket 12 and the top cover 13. Specifically, the top cover 13 is arranged on the side of the main body 122 away from the base 11, and the top cover 13 and the main body 122 are connected, and the atomization core 2 is clamped and fixed between the main body 122 and the top cover 13. The bracket 12 and the top cover 13 can be snap-fit connected, for example, a groove is arranged on the bracket 12, and a protrusion is arranged on the top cover 13, and the bracket 12 and the top cover 13 are buckled together through the cooperation of the protrusion and the groove. The main body 122 of the bracket 12 is provided with a first central through hole 110, and the top cover 13 is provided with a second central through hole 120, and the first central through hole 110 and the second central through hole 120 are communicated, and together form the air outlet hole 103.

[0050] Further, as shown in the embodiments, Figures 5 to 7 In some embodiments, the heating body 21 is in a sheet shape. Since the sheet-shaped heating body 21 has a very small thickness, sufficient support force is needed to ensure that it will not be deformed. Therefore, the atomization seat 1 further comprises at least two support members 15 for further supporting and fixing the heating body 21. The support member 15 is arranged between the heating body 21 and the bracket 12. The support member 15 can be an elastic member, for example, it can be made of silicone, rubber, silicone rubber, etc. The number of support members 15 can be consistent with the number of heating bodies 21. As shown in the embodiments, Figures 5 to 7 In some embodiments, the heating body 21 is in a sheet shape. Since the sheet-shaped heating body 21 has a very small thickness, sufficient support force is needed to ensure that it will not be deformed. Therefore, the atomization seat 1 further comprises at least two support members 15 for further supporting and fixing the heating body 21. The support member 15 is arranged between the heating body 21 and the bracket 12. The support member 15 can be an elastic member, for example, it can be made of silicone, rubber, silicone rubber, etc. The number of support members 15 can be consistent with the number of heating bodies 21. As shown in the embodiments, Figure 5 、 Figures 7 to 9As shown, in some embodiments, the flow guide structure 5 is protruded on the bottom surface of the atomization cavity 102. Specifically, the bottom surface of the atomization cavity 102 can be the surface of the base 11 facing the main body 122 of the holder 12. In other words, the bottom surface of the atomization cavity 102 can be the surface of the bottom wall 112 of the base 11 facing the main body 122 of the holder 12. The bottom surface of the atomization cavity 102 is a plane. The flow guide structure 5 has a flow guide surface 50, which is inclined relative to the bottom surface of the atomization cavity 102, and an included angle between the flow guide surface 50 and the bottom surface of the atomization cavity 102 is less than 90°. The flow guide surface 50 includes at least one of a slope surface and a tapered surface. That is, the flow guide surface 50 can be a slope surface or a tapered surface, or a combination of a slope surface and a tapered surface. As shown in FIG. 1A, Figure 8 As shown, in some embodiments, the flow guide surface 50 is a tapered surface, that is, the flow guide structure 5 is substantially conical, and the tapered surface has a pointed end. As shown in FIG. 1A, Figure 9 As shown, in some other embodiments, the flow guide surface 50 includes two slope surfaces, which are symmetrically arranged about the central axis of the air outlet hole 103, and the flow guide structure 5 is substantially a triangular prism. However, a transition plane is connected between the two slope surfaces, so that the upper surface of the flow guide structure 5 is smoother.

[0051] As shown in FIG. 1A, Figure 10 and Figure 11 As shown, in some embodiments, each heating element 21 includes a conductive part 211 and at least one heating part 212 connected to the conductive part 211. The conductive part 211 is connected to the power supply unit 6 and serves as a conductive electrode. The aerosol generating substrate is mainly heated and atomized at the heating part 212. The heating part 212 is exposed to the airflow channel. That is, the number of heating parts 212 can be one, two, three, four, etc. As shown in FIG. 1A, Figure 10 and Figure 11 In the embodiment shown, the conductive part 211 includes a first part 2111 and a second part 2112. The first part 2111 and the second part 2112 serve as a positive electrode and a negative electrode, respectively, and are connected to the power supply unit 6. The opposite ends of each heating part 212 are connected to the first part 2111 and the second part 2112, respectively. As shown in FIG. 1A, Figure 10 In the embodiment shown, each heating element 21 includes one heating part 212, and the opposite ends of the heating part 212 are connected to the first part 2111 and the second part 2112, respectively. As shown in FIG. 1A, Figure 11 In the embodiment shown, each heating element 21 includes two heating parts 212, and the opposite ends of each heating part 212 are connected to the first part 2111 and the second part 2112, respectively, and the heating parts 212 do not directly contact each other.

[0052] As shown in FIG. 1A, Figure 10 and Figure 11As shown, the heating element 212 has a planar mesh structure in some embodiments. Alternatively, in other embodiments, the heating element 212 may also be spiral-shaped, etc. Corresponding to the above description, the first circuit board 61 is connected to the heating element 21 through conductive posts 611. The conductive posts 611 pass through the first mounting hole 101 and the through hole 123 in sequence and are then connected to the conductive element 211. Specifically, each conductive element 211 covers the corresponding through hole 123, and the end of the conductive post 611 away from the first circuit board 61 abuts against the position of the conductive element 211 exposed in the through hole 123, thereby realizing the electrical connection between the first circuit board 61 and the heating element 21.

[0053] In some embodiments, when each heating element 21 includes at least two heating sections 212, at least two heating sections 212 are connected in parallel. Alternatively, at least two heating elements 21 are connected in parallel. Alternatively, both heating elements 21 and at least two heating sections 212 of each heating element 21 are connected in parallel. Since the different heating sections 212 or heating elements 21 are connected in parallel in the circuit of the power supply unit 6, the power supply unit 6 can control the power supply and power-off of each heating element 21 or heating section 212, as well as the output power, etc. By setting each heating element 21 or heating section 212 to a different output power, the amount of mist produced and the mist rate can be adjusted.

[0054] Use two such Figure 11 When the heating element 21 with dual heating elements is shown, the atomization area is large, and the overall power of the atomizing core 2 is relatively high. For example... Figure 12 As shown, according to actual measurements, the power of the atomizing core 2 can reach 30W, and the TPM (Total Particle Measure, i.e., the average amount of vapor produced per inhalation) is 17.9mg / puff, which exceeds the standard value (10mg / puff) by 7.9mg / puff.

[0055] Furthermore, such as Figures 4 to 7 As shown, in some embodiments, the atomizing core 2 further includes at least one liquid guiding surface 22.
