[0002] In the existing atomization device, the oil-conducting ceramic of the ceramic atomization core is placed horizontally in the airway tube, and the heating wire is arranged at the bottom of the oil-conducting ceramic. The heating wire heats the atomization matrix to generate aerosol. The aerosol generated at the bottom of the oil-conducting ceramic needs to bypass the side wall of the oil-conducting ceramic before entering the nozzle. The obstruction of the oil-conducting ceramic increases the flow resistance of the aerosol, resulting in poor aerosol flow, taste attenuation, and poor user experience. Summary of the invention

[0006] The atomization component provided in the present application has a heating part arranged on the side wall of the gas channel and adjacent to the gas channel, and the heating part is arranged vertically along the air inlet pipe.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] This application provides an atomization assembly. Figure 1 to Figure 4 , the atomization assembly 100 may include an oil tank 10, a suction nozzle 20, an oil suction member 30 and an atomization core 40. The oil tank 10 is used to store an atomization matrix, which can be atomized to generate an aerosol when heated, and the aerosol reaches the end of the user's inhalation through the suction nozzle 20. One end of the oil tank 10 is open, and the suction nozzle 20 is covered on the open end of the oil tank 10. An air inlet pipe 11 is arranged in the oil tank 10, and the air inlet pipe 11 is in a hollow cylindrical shape. The air inlet pipe 11 is connected to the suction nozzle 20 to form a gas channel. It should be noted that other components that are connected to the air inlet pipe 11 and the suction nozzle 20 at the same time can be arranged between the air inlet pipe 11 and the suction nozzle 20. The gas channel is the gas path, and the inner wall of the gas path is a general term for the inner wall of the through-hole structure that is interconnected by the various components that together constitute the gas path. The atomization core 40 is installed at one end of the air inlet pipe 11 close to the suction nozzle 20.

[0022] The atomizer core 40 includes a heating portion 42, which is disposed on the side wall of the gas passage and adjacent to the gas passage, and the heating portion 42 is disposed vertically along the air inlet pipe 11. The heating portion 42 is disposed vertically along the air inlet pipe 11, which means that the plane where the heating portion 42 is located is parallel to the extension direction of the air inlet pipe 11, or the angle between the plane where the heating portion 42 is located and the extension direction of the air inlet pipe 11 is relatively small. With such an arrangement, on the one hand, the heating portion 42 is close to the side wall of the air inlet pipe 11, which can prevent the heating portion 42 from obstructing the flow of the aerosol in the air inlet pipe 11, thereby reducing the flow resistance of the aerosol and improving the taste of the aerosol; on the other hand, the heating portion 42 is vertically along the air inlet pipe 11, and the plane where the heating portion 42 is located is parallel to the extension direction of the air inlet pipe 11 or the angle between the two is relatively small, so that the flow direction of the aerosol is roughly parallel to the plane where the heating portion 42 is located, further reducing the flow resistance of the aerosol, allowing the aerosol to flow smoothly in the air inlet pipe 11, and reducing the taste attenuation of the aerosol.

[0023] One end of the oil suction member 30 abuts against the atomizer core 40 to achieve fluid communication, and the opposite end of the oil suction member 30 is accommodated in the oil tank 10 and extends to the end away from the suction nozzle 20. The oil suction member 30 transfers the atomized matrix stored in the oil tank 10 to the atomizer core 40, and the heating part 42 is used to atomize the atomized matrix in the atomizer core 40 into an aerosol.

[0024] In the atomization assembly 100 provided in the present application, the heating part 42 is arranged on the side wall of the gas channel and is adjacent to the gas channel, and the heating part 42 is arranged vertically along the air inlet pipe 11. Since there is no heating part 42 blocking the gas channel, the gas takes away the aerosol atomized on the surface of the heating part 42 when flowing through the surface of the heating part 42. The flow direction of the aerosol is roughly parallel to the plane where the heating part 42 is located. Therefore, the aerosol can flow smoothly to the suction nozzle 20, reducing the taste attenuation of the aerosol and improving the user experience.

[0025] See also Figure 5The oil bin 10 may include an oil bin side wall 12 and an oil bin bottom plate 13. The oil bin bottom plate 13 is connected to one end of the oil bin side wall 12 away from the suction nozzle 20. The air inlet pipe 11 is connected to the oil bin bottom plate 13. The oil bin side wall 12, the oil bin bottom plate 13 and the air inlet pipe 11 are arranged to form a receiving chamber 14. The atomized matrix is ​​stored in the receiving chamber 14. An opening is provided at one end of the receiving chamber 14 close to the suction nozzle 20. When the oil bin 10 is placed upright, oil can be pre-filled at the top of the oil bin 10 through the opening. After the oil filling, other components can be directly assembled on the oil bin 10, which is conducive to automated assembly. The conventional solution adopts the method of filling oil from the bottom of the oil bin. It is necessary to first invert the oil bin, close the bottom of the oil bin after the oil filling is completed, and then flip it upright to assemble other components, which increases the assembly time and cost. In addition, since the atomizer core 40 is installed at one end of the oil tank 10 close to the suction nozzle 20, the oil suction member 30 absorbs the atomized matrix in the accommodating chamber 14 to the atomizer core 40, so there is no need to set an opening at the bottom of the accommodating chamber 14 to transport the matrix to the atomizer core, which can solve the problem that the atomized matrix is ​​easy to leak from the bottom opening of the accommodating chamber 14 under gravity. The oil tank 10 can be made of plastic, and the air inlet pipe 11, the oil tank side wall 12 and the oil tank bottom plate 13 can be integrally processed and formed.

[0026] In one embodiment, if Figure 6 As shown, the atomizer core 40 also includes an oil guide 41, which is used to adsorb the atomized matrix to the heating part 42, and the oil guide 41 abuts against the oil absorption part 30 to achieve fluid communication. The oil guide 41 can be installed on the side wall of the gas channel to prevent the oil guide 41 from obstructing the flow of aerosol in the gas channel. The oil guide 41 can be a porous ceramic material. The ceramic material has controllable precision, high mass production, and good lipophilicity and oil locking properties. Compared with fiber materials, the oil guide 41 made of ceramic material has a certain rigidity, is not easy to deform, is easy to use automated assembly, can improve assembly efficiency, and reduce production costs. The oil guide 41 has a first surface 4111 adjacent to the gas channel and parallel to the axis of the gas channel, and the heating part 42 is arranged on the first surface 4111 of the oil guide. The heating part 42 can be a resistive heating wire formed on the ceramic oil guide 41 by electroplating, printing and other processes, and the material of the heating part 42 can be one of stainless steel, nickel-chromium-aluminum alloy, nickel-chromium alloy, iron-chromium-aluminum or titanium alloy.

[0027] The heating portion 42 has a designed pattern, which can increase the contact area between the heating portion 42 and the atomizing substrate. The heating portion 42 is disposed on the first surface 4111 of the oil guide 41, so that the first surface 4111 of the oil guide 41 needs to have a larger surface area, which may increase the volume of the oil guide 41 and squeeze the installation space of other components in the atomizing assembly 100. In one embodiment, Figure 6As shown, the oil guide member 41 includes an integrally arranged atomizing portion 411 and a mounting portion 412, and the cross-sectional area of ​​the mounting portion 412 in the axial direction of the gas passage is smaller than the cross-sectional area of ​​the atomizing portion 411. The first surface 4111 is arranged on the atomizing portion 411, and the mounting portion 412 is connected to the second surface 4112 of the atomizing portion 411 opposite to the first surface 4111, and the mounting portion 412 abuts against the oil suction member 30 to achieve fluid communication. The cross-sectional area of ​​the mounting portion 412 in the axial direction of the gas passage is arranged to be smaller than the cross-sectional area of ​​the atomizing portion 411, so as to reduce the overall volume of the oil guide member 41 and facilitate the installation of other components.

[0028] In one embodiment, the first surface 4111 is parallel to the second surface 4112. When the oil guide member 41 is assembled to the side wall of the gas channel, illustratively, when the oil guide member 41 is assembled to the air inlet pipe 11, the robot arm can be clamped on two mutually parallel surfaces, so that the clamping of the robot arm is more stable, which is convenient for realizing automated operation and improving assembly efficiency. Optionally, the atomization part 411 can be a block-shaped rectangular parallelepiped, and the dimensions of the atomization part 411 in various directions are different. The installation direction of the atomization core 40 can be identified by the external dimensions to ensure the accuracy of the installation direction.

[0029] Users have increasingly higher requirements for the taste of aerosols, and specific evaluation indicators may include sweetness, coolness, fullness of aroma, absence of burnt taste, etc. In the prior art, the method of adjusting the atomization device to satisfy the taste can only improve one of the indicators, but may reduce another indicator. For example, the sweetness of the aerosol can be improved by increasing the heating power of the atomization core, but high-power heating can cause a burnt taste; for another example, the sweetness can be improved by adjusting the components of the atomization matrix, but the atomization matrix with higher sweetness is prone to carbon deposits in the aerosol generated by atomization, thereby affecting the taste. In the present application, by installing the atomization core 40 at one end of the air inlet pipe 11 close to the nozzle 20, the distance from the aerosol to the user's inhalation end is reduced, and various indicators of the aerosol can be comprehensively improved. In some embodiments, such as Figure 3 As shown, the distance d between the atomizer core 40 and the end of the suction nozzle 20 away from the oil tank 10 is less than 20 mm. The distance d here refers to the length between the upper edge of the atomizer core 40 and the upper edge of the suction nozzle 20. In conventional solutions, the distance between the atomizer core 40 and the suction nozzle 20 is usually more than 40 mm, resulting in a decay of the taste of the aerosol when it reaches the user's inhalation end, and a poor user experience. Specifically, the distance d between the atomizer core 40 and the suction nozzle 20 can be 20 mm, 18 mm, 16 mm, 15 mm, etc., which is not specifically limited here.

[0030] The oil absorption member 30 can be a porous fiber material, such as one or more of fiber cotton, non-woven fabrics, linen, chemical fiber fabrics, etc. The above materials have good lipophilicity and oil locking properties, which can ensure the supply rate of the atomized matrix. In the prior art, the atomizer core is arranged at the lower part of the oil bin, and the atomized matrix in the oil bin generates hydraulic pressure due to gravity. The atomized matrix flows to the atomizer core under the action of the hydraulic pressure, and the size of the hydraulic pressure in the oil bin determines the supply of the atomized matrix in the atomizer core. During the use of the atomizer device, part of the atomized matrix is ​​atomized to generate aerosol, and the atomized matrix gradually decreases. The hydraulic pressure in the oil bin decreases accordingly, and the rate at which the atomized matrix flows to the atomizer core decreases. The change in the supply rate of the atomized matrix will cause the atomized aerosol generated by the atomization of the atomizer core to be inconsistent in taste, affecting the user experience. In the present application, the atomizer core 40 is installed on the upper part of the oil tank 10, and the atomizer matrix stored in the oil tank 10 is adsorbed to the atomizer core 40 through the oil absorption member 30, so that the supply rate of the atomizer matrix in the atomizer core 40 depends only on the adsorption force of the oil absorption member 30, and the adsorption force of the oil absorption member 30 is the property of the material itself and has nothing to do with the hydraulic pressure of the atomizer matrix in the oil tank 10. The reduction of the atomizer matrix in the oil tank 10 will not affect the supply rate of the atomizer matrix, and the supply rate of the atomizer matrix is ​​stable, thereby ensuring the consistency of the taste of the aerosol generated by atomization.

[0031] The oil suction member 30 can be arranged in a variety of ways. Figure 7 As shown, the oil suction member 30 is columnar. The cross-sectional shape of the oil suction member 30 can be circular, polygonal or irregular, and can be set as needed. An oil suction member installation groove 15 is provided in the oil bin 10, and the oil suction member installation groove 15 extends along the longitudinal direction of the oil bin 10 to the bottom of the oil bin 10, and the oil suction member 30 is installed in the oil suction member installation groove 15. On the one hand, the oil suction member installation groove 15 can be used for positioning when assembling the oil suction member 30, which is convenient for the installation of the oil suction member 30; on the other hand, after the oil suction member 30 is assembled to the oil suction member installation groove 15, the oil suction member installation groove 15 can limit the displacement of the oil suction member 30, thereby ensuring the stability of the oil supply of the oil suction member 30. The oil suction member installation groove 15 can be set on the inner wall of the oil bin side wall 12, and can also be set on the outer wall of the air intake pipe 11.

[0032] In another embodiment, if Figure 8As shown, the oil suction member 30 is cylindrical, and the oil suction member 30 is sleeved on the outer periphery of the air inlet pipe 11, and the oil suction member 30 extends to the bottom of the oil bin 10 along the longitudinal direction of the oil bin 10. The oil suction member 30 is sleeved on the air inlet pipe 11, and the air inlet pipe 11 can be used for the installation and positioning of the oil suction member 30, and can prevent the oil suction member 30 from shifting after installation. There is no need to set up an additional positioning or limiting component for the oil suction member 30, which simplifies the structure of the atomization assembly 100. In addition, the oil suction member 30 is evenly covered outside the air inlet pipe 11, which increases the contact surface between the oil suction member 30 and the atomized matrix, and can ensure the supply rate of the atomized matrix. Optionally, the oil suction member 30 can be filled in the oil storage space between the oil bin 10 and the air inlet pipe 11, so that the atomized matrix is ​​directly stored in the oil suction member 30.

[0033] In one embodiment, if Figure 3 , Fig. 9 As shown, the atomizer assembly 100 is provided with a sealing seat 50, which is arranged between the suction nozzle 20 and the oil tank 10, and the sealing seat 50 is connected to the suction nozzle 20 and the air inlet pipe 11 respectively, and the atomizer core 40 is installed on the sealing seat 50. The sealing seat 50 can be made of silicone material, which has good compressibility. When the sealing seat 50 is assembled between the suction nozzle 20 and the oil tank 10, the sealing seat 50 is compressed and deformed to seal the oil tank 10, thereby preventing leakage of the atomized matrix.

[0034] The sealing seat 50 may include a seat body 51 and a sealing portion 52 connected as an integral structure. The opposite sides of the sealing portion 52 are respectively in contact with the suction nozzle 20 and the oil tank 10 to seal the oil tank 10. The sealing portion 52 is provided with a sealing portion air inlet hole 521 for connecting the suction nozzle 20 and the air inlet pipe 11, so that the aerosol can reach the end of the user's inhalation through the sealing seat 50. The seat body 51 is connected to the side of the sealing portion 52 away from the suction nozzle 20. The seat body 51 has a mounting surface 511 extending vertically along the air inlet pipe 11. The mounting surface 511 is located on one side of the sealing portion air inlet hole 521, so that there is no obstruction in the air inlet pipe 11, and the flow direction of the aerosol is roughly parallel to the mounting surface 511, thereby reducing the flow resistance of the aerosol. The seat body 51 is provided with a mounting cavity 512, which runs through the mounting surface 511, and the atomizer core 40 is installed in the mounting cavity 512. Specifically, the first surface 4111 of the atomization portion 411 may be parallel to the mounting surface 511 to reduce the flow resistance of the aerosol.

[0035] In one embodiment, if Figure 4 , Figure 5 As shown, a mounting hole 111 is provided at the end of the air inlet pipe 11 close to the suction nozzle 20, and the seat body 51 is installed in the mounting hole 111. The mounting hole 111 can prevent the sealing seat 50 from shifting.

[0036] Please continue reading Figure 4 , Figure 5, a diaphragm 112 and a convex rib 113 are provided in the air inlet pipe 11. The diaphragm 112 is connected to the inner wall of the air inlet pipe 11, and an air inlet hole 114 is provided on the diaphragm 112. The suction resistance of the atomization assembly 100 can be adjusted by adjusting the size of the air inlet hole 114, so that the user can experience the taste brought by different suction resistances. The convex rib 113 is strip-shaped, and the convex rib 113 extends along the longitudinal direction of the air inlet pipe 11. A plurality of convex ribs 113 are distributed at intervals and connected to the inner wall of the air inlet pipe 11, and one end of the convex rib 113 is connected to the side of the diaphragm 112 away from the suction nozzle 20.

[0037] As the aerosol flows toward the nozzle 20, as the aerosol moves away from the heating portion 42, the temperature of the aerosol decreases, and part of the aerosol liquefies to form condensate. Under the action of gravity, the condensate flows along the nozzle 20 and the inner wall of the air inlet pipe 11 toward the end away from the nozzle 20. The condensate may cause some components of the atomization device to fail. In order to recover the condensate, in one embodiment, Figure 3 As shown, the air inlet pipe 11 is provided with oil-absorbing cotton 60, which can absorb condensed liquid, thereby reducing the risk of failure of some components caused by condensed liquid. The oil-absorbing cotton 60 abuts against the end of the rib 113 away from the suction nozzle 20, and the rib 113 can prevent the oil-absorbing cotton 60 from shifting.

[0038] See also Figure 3 In one embodiment, an electrode blind hole 131 is provided on the side of the oil bin bottom plate 13 away from the suction nozzle 20, and the electrode blind holes 131 are distributed on both sides of the end of the air intake pipe 11. The heating part 42 is connected with a heating part pin 43, and the heating part pin 43 passes through the oil bin bottom plate 13 and is bent toward the electrode blind hole 131 and attached to the inner wall of the electrode blind hole 131. The electrode 70 is inserted into the electrode blind hole 131, and the electrode 70 is electrically connected to the heating part pin 43. By providing the electrode blind hole 131, the installation and alignment of the electrode 70 can be facilitated to adapt to automated assembly, thereby improving assembly efficiency.

[0039] This application provides an atomization device. Fig.10 , 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 substrate to generate aerosol or stop heating. Specifically, when inhaling through the mouthpiece 20, 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 substrate 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 substrate.

[0040] The atomizer assembly provided in this application has at least the following beneficial effects:

[0041] 1. The heating portion 42 is arranged on the side wall of the gas passage and is adjacent to the gas passage, and the heating portion 42 is arranged along the vertical direction of the air inlet pipe 11. Since there is no heating portion 42 blocking the gas passage, the gas takes away the aerosol atomized on the surface of the heating portion 42 when flowing through the surface of the heating portion 42. The flow direction of the aerosol is roughly parallel to the plane where the heating portion 42 is located. Therefore, the aerosol can flow smoothly to the suction nozzle 20, reducing the taste attenuation of the aerosol and improving the user experience.

[0042] 2. The atomizer core 40 is installed at one end of the oil tank 10 close to the suction nozzle 20. The oil suction member 30 absorbs the atomized matrix in the accommodating chamber 14 to the atomizer core 40. There is no need to set an opening at the bottom of the accommodating chamber 14 to transport the matrix to the atomizer core, which can solve the problem that the atomized matrix is ​​easy to leak from the bottom opening of the accommodating chamber 14 under gravity.

[0043] 3. In the axial direction of the gas passage, the cross-sectional area of ​​the mounting portion 412 is smaller than the cross-sectional area of ​​the atomizing portion 411 , which can reduce the overall volume of the oil guide member 41 and facilitate the installation of other components.

[0044] 4. The distance d between the atomizer core 40 and the end of the nozzle 20 away from the oil tank 10 is less than 20 mm, which reduces the distance for the aerosol to reach the end where the user inhales, and can comprehensively improve various indicators of the aerosol.

[0045] 5. The oil absorption member 30 absorbs the atomized matrix stored in the oil tank 10 to the atomization core 40, so that the supply rate of the atomized matrix in the atomization core 40 depends only on the adsorption force of the oil absorption member 30. The supply rate of the atomized matrix is ​​stable, which can ensure the consistency of the taste of the aerosol generated by atomization.

[0046] 6. When the oil suction member 30 is arranged in a columnar shape, an oil suction member installation groove 15 is provided in the oil tank 10. The oil suction member 30 is installed in the oil suction member installation groove 15, which can facilitate the installation and positioning of the oil suction member 30 and limit the displacement of the oil suction member 30, thereby ensuring the stability of the oil supply of the oil suction member 30.

[0047] 7. When the oil suction member 30 is arranged in a cylindrical shape, the oil suction member 30 is sleeved on the outer periphery of the air inlet pipe 11. On the one hand, the air inlet pipe 11 can be used for the installation and positioning of the oil suction member 30, and can prevent the oil suction member 30 from shifting after installation, thereby simplifying the structure of the atomization assembly 100; on the other hand, the oil suction member 30 is evenly covered on the outside of the air inlet pipe 11, thereby increasing the contact surface between the oil suction member 30 and the atomization matrix, thereby ensuring the supply rate of the atomization matrix.

[0048] The above descriptions are only some embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any equivalent device or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
