Description

Atomization components and atomization devices

Technical field

[0001] The present invention relates to the technical field of electronic atomizers, and in particular to an atomization assembly and an atomization device. [Background Technology]

[0002] In existing atomizers, the atomized matrix is ​​stored in an oil cup, which is connected to the atomizer core. Gravity creates hydraulic pressure on the atomized matrix in the oil cup, which flows toward the atomizer core. The supply rate of the atomized matrix depends on the hydraulic pressure in the oil cup. During use, some of the atomized matrix is ​​atomized to form aerosol, gradually reducing the amount of atomized matrix. This decreases the hydraulic pressure in the oil cup, reducing the rate at which the atomized matrix flows toward the atomizer core. This change in the atomized matrix supply rate results in inconsistent flavors in the aerosol generated by the atomizer core, impacting the user experience.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0031] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The present application provides an atomization assembly. Referring to Figures 1 to 4, the atomization assembly 100 may include an oil cup 10, a suction nozzle 20, an oil suction member 30, and an atomization core 40. The suction nozzle 20 is arranged at one end of the oil cup 10. The oil cup 10 is used to store an atomization matrix. The atomization matrix can be atomized to generate an aerosol when heated, and the aerosol reaches the end where the user inhales through the suction nozzle 20. An atomization tube 11 is provided in the oil cup 10, and the atomization tube 11 is connected to the suction nozzle 20. An atomization chamber 111 connected to the atomization tube 11 is provided at one end of the oil cup 10 close to the suction nozzle 20, and an oil storage chamber 14 for storing the atomization matrix is ​​provided at the opposite end of the oil cup 10 away from the suction nozzle 20. The atomization core 40 is installed in the atomization chamber 111.

[0033] One end of the oil absorbing member 30 contacts the atomizer core 40, and the other end of the oil absorbing member 30 extends into the oil storage chamber 14. The oil absorbing member 30 is used to transfer the atomized matrix to the atomizer core 40. The oil absorbing member 30 can contact the atomizer core 40 at any part of the oil absorbing member 30, as long as the two can be fluidically connected after contact. For example, the top end of the oil absorbing member 30 can abut the bottom end of the atomizer core 40, or the side of the oil absorbing member 30 can be attached to the side of the atomizer core 40, or the oil absorbing member 30 can be wrapped around the outer periphery of the atomizer chamber 111, and an oil hole is opened in the atomizer chamber 111, and the oil absorbing member 30 contacts the atomizer core 40 through the oil hole.

[0034] The atomizing core 40 includes a heating element 42, which is arranged on the first surface 411 of the atomizing core 40. The first surface 411 is arranged along the axial direction of the atomizing tube 11, and the heating element 42 is used to heat the atomizing matrix to generate an aerosol. The axial arrangement of the first surface 411 along the atomizing tube 11 means that the first surface 411 is parallel to the extension direction of the atomizing tube 11, or the angle between the first surface 411 and the extension direction of the atomizing tube 11 is relatively small. Such an arrangement makes the flow direction of the aerosol roughly parallel to the first surface 411, reducing the flow resistance of the aerosol, and the aerosol can flow smoothly in the atomizing chamber 111, reducing the taste attenuation of the aerosol, and improving the taste of the aerosol.

[0035] A pair of first electrodes 50 are installed in the atomizer tube 11, and one end of the first electrode 50 abuts against the heater 42. The first electrode 50 is electrically connected to the heater 42. The atomizer core 40 is connected to a power source through the first electrode 50, and the power source provides power for the operation of the atomizer core 40.

[0036] The atomization assembly 100 provided in the present application has an atomization core 40 installed in the atomization chamber 111 at one end of the oil cup 10 close to the suction nozzle 20, and an oil storage chamber 14 is provided at the end of the oil cup 10 away from the suction nozzle 20. The oil suction member 30 absorbs the atomization matrix stored in the oil storage chamber 14 to the atomization core 40, so that the supply rate of the atomization matrix depends only on the adsorption force of the oil suction member 30 and has nothing to do with the hydraulic pressure of the atomization matrix in the oil cup 10. The reduction of the atomization matrix in the oil cup 10 will not affect the supply rate of the atomization matrix. The supply rate of the atomization matrix is ​​stable, thereby ensuring the consistency of the taste of the aerosol generated by atomization.

[0037] The atomizing core 40 also includes an oil guide 41. As shown in FIG4 , the oil guide 41 is used to adsorb the atomized matrix to the heating element 42. The heating element 42 heats the atomized matrix to generate an aerosol. The oil guide 41 is in fluid communication with the oil absorbing element 30. The oil guide 41 is a porous medium, and the oil guide 41 can be a porous ceramic material. The precision of ceramic materials is controllable, mass-producible, and has 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, and is easy to use for automated assembly, which can improve assembly efficiency and reduce production costs. The oil guide 41 is arranged adjacent to the side wall of the atomizing tube 11, and the first surface 411 is arranged on the side of the oil guide 41 adjacent to the inner wall of the atomizing tube 11. The heating element 42 is arranged on the first surface 411 of the oil guide 41. Positioning the heater 42 on the first surface 411 adjacent to the inner wall of the atomizer tube 11 prevents the heater 42 from obstructing the flow of the aerosol within the atomizer tube 11, thereby reducing the flow resistance of the aerosol and improving the flavor of the aerosol. The heater 42 may be a resistive heating wire formed on the ceramic oil guide 41 using a process such as electroplating or printing. The heater 42 may be made of stainless steel, nickel-chromium-aluminum alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium alloy.

[0038] In one embodiment, as shown in FIG4 , the oil guide member 41 has a second surface 412 opposite the first surface 411, with the first surface 411 being parallel to the second surface 412. When the oil guide member 41 is assembled onto the atomizer tube 11, the robotic arm can clamp it on two mutually parallel surfaces, making the robotic arm's clamping more stable, facilitating automated operation, and improving assembly efficiency. The oil guide member 41 can be a block-shaped rectangular parallelepiped, with different dimensions in various directions. The external dimensions can be used to identify the installation direction of the atomizer core 40, ensuring the accuracy of the installation direction.

[0039] Users have increasingly higher requirements for the taste of aerosols, and specific evaluation indicators may include sweetness, coolness, fullness of aroma, and absence of burnt taste. In the prior art, the method of adjusting the atomization device to meet the taste can only improve one of the indicators, but may reduce another indicator. For example, increasing the heating power of the atomizer core to improve the sweetness of the aerosol, but high-power heating will cause a burnt taste; for another example, adjusting the components of the atomizer matrix to improve the sweetness, but atomizer matrices with higher sweetness are prone to carbon deposits in the aerosol generated by atomization, affecting the taste. In the present application, by installing the atomizer core 40 at the end of the atomizer tube 11 close to the suction 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, as shown in Figure 4, the distance d between the atomizer core 40 and the end of the suction nozzle 20 away from the oil cup 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 mouthpiece 20 is typically greater than 40 mm, resulting in a poor user experience due to a reduced flavor when the aerosol reaches the inhalation end. Specifically, the distance d between the atomizer core 40 and the mouthpiece 20 can be 20 mm, 18 mm, 16 mm, 15 mm, and so on, without specific limitation.

[0040] In one embodiment, the first electrode 50 is a spring, the fixed end of the spring is relatively fixed to the atomizer tube 11, and the free end of the spring is in close contact with the heating element 42. The first electrode 50 is set as a spring so that the first electrode 50 has a certain elasticity. When the atomizer core 40 is assembled, the atomizer core 40 pushes the first electrode 50 to undergo a certain elastic deformation. The elastically deformed first electrode 50 is in close contact with the atomizer core 40 under the action of the elastic restoring force, thereby ensuring the reliability of the electrical connection between the first electrode 50 and the atomizer core 40. In the existing atomizer device, the heating element of the atomizer core is provided with a pin, and the heating element is connected to the power supply through the pin. The pin is usually a flexible wire with low bending stiffness. The pin is easy to bend during assembly, which makes it difficult to assemble the pin and position it, making it difficult to realize the automated assembly of the atomizer core, thereby reducing the assembly efficiency. In the present application, by providing the first electrode 50, the atomizer core 40 does not need to be connected to the power supply through pins. The first electrode 50 has greater rigidity than the pins and will not bend during assembly, making the alignment between the atomizer core 40 and the first electrode 50 convenient, which is beneficial to the automated assembly of the atomizer core 40 and can improve assembly efficiency.

[0041] Please refer to Figure 4. The oil cup 10 may include an oil cup side wall 12 and an oil cup bottom plate 13. The oil cup bottom plate 13 is connected to the end of the oil cup side wall 12 away from the suction nozzle 20. The atomizing tube 11 is connected to the oil cup bottom plate 13. The oil cup side wall 12, the oil cup bottom plate 13 and the atomizing tube 11 are surrounded by an oil storage chamber 14. The atomized matrix is ​​stored in the oil storage chamber 14. The oil storage chamber 14 is provided with an opening at one end close to the suction nozzle 20. When the oil cup 10 is placed upright, the top of the oil cup 10 can be pre-filled with oil through the opening. After oiling, other components can be directly assembled on the oil cup 10, which is conducive to automated assembly. The conventional solution uses oiling from the bottom of the oil cup. It is necessary to first turn the oil cup upside down, seal the bottom of the oil cup after oiling, and then flip it upright to assemble other components, which increases assembly time and cost. Furthermore, because the atomizer core 40 is mounted on the end of the oil cup 10 near the nozzle 20, the oil suction element 30 absorbs the atomized matrix from the oil reservoir 14 into the atomizer core 40. This eliminates the need for an opening at the bottom of the oil reservoir 14 to deliver the matrix to the atomizer core. This solves the problem of the atomized matrix easily leaking from the bottom opening of the oil reservoir 14 under gravity. The oil cup 10 can be made of plastic, and the atomizer tube 11, oil cup sidewall 12, and oil cup bottom plate 13 can be integrally formed.

[0042] The oil absorber 30 can be made of a porous fiber material, such as fiber cotton, non-woven fabric, linen, or synthetic fabric. These materials all have excellent lipophilicity and oil-binding properties, ensuring a high supply rate for the atomized substrate. The oil absorber 30 can be configured in a variety of ways. In one embodiment, as shown in Figure 5 , the oil absorber 30 is cylindrical. Its cross-section can be circular or polygonal, depending on the application. The oil cup 10 includes an oil absorber mounting groove 15, into which the oil absorber 30 is mounted. The oil absorber 30 extends longitudinally along the oil cup 10 to the bottom of the oil storage chamber 14. The mounting groove 15 facilitates positioning of the oil absorber 30 during assembly and, once installed, prevents displacement, thereby ensuring stable oil supply. The oil suction member installation groove 15 can be provided on the inner wall of the oil cup side wall 12 or on the outer wall of the atomizing tube 11 .

[0043] In another embodiment, as shown in Figure 6 , the oil absorbing member 30 is cylindrical and is mounted on the outer periphery of the atomizing tube 11. The oil absorbing member 30 extends longitudinally along the oil cup 10 to the bottom of the oil storage chamber 14. The oil absorbing member 30 is mounted on the atomizing tube 11, which serves to position and secure the oil absorbing member 30 and prevent displacement after installation. This eliminates the need for additional positioning or limiting components for the oil absorbing member 30, simplifying the structure of the atomizing assembly 100. Furthermore, the oil absorbing member 30 evenly covers the exterior of the atomizing tube 11, increasing the contact surface between the oil absorbing member 30 and the atomized substrate, thereby ensuring a high supply rate for the atomized substrate.

[0044] The atomizing chamber 111 can be arranged in a variety of ways. For example, the atomizing chamber 111 can be a section of the atomizing tube 11 close to the suction nozzle 20, that is, the oil guide member 41 can be directly assembled in the atomizing tube 11. The oil guide member 41 can also be assembled at the end of the atomizing tube 11 through a bracket 60. As shown in Figures 3 and 7, the atomizing assembly 100 is provided with a bracket 60, which is installed between the suction nozzle 20 and the oil cup 10. The bracket 60 is arranged to form the atomizing chamber 111. The bracket 60 is connected to the suction nozzle 20 and the atomizing tube 11 respectively, and the oil guide member 41 is installed on the inner wall of the bracket 60. The bracket 60 can prevent the oil guide member 41 from shifting, thereby improving the reliability of the atomizing assembly 100. When assembling the atomizing assembly 100, the oil guide member 41 can be assembled to the bracket 60 first, and then the bracket 60 can be assembled into the oil cup 10. The bracket 60 can be made of silicone, which has good compressibility. When the bracket 60 is assembled between the nozzle 20 and the oil cup 10, the bracket 60 compresses and deforms to seal the oil cup 10, preventing leakage of the atomized matrix. The bracket 60 can also be made of plastic, which has high strength and is less prone to deformation, thus preventing the oil guide 41 from shifting. When the bracket 60 is made of plastic, a silicone ring can be installed at the contact point between the bracket 60 and the oil cup 10 to enhance the airtightness of the atomizer assembly 100. A silicone seat can also be provided at the installation point of the oil guide 41 to secure the oil guide 41 by utilizing the compressibility of silicone.

[0045] Continuing with Figures 3 and 7 , a partition 61 is attached to the inner wall of the bracket 60 and positioned along the axis of the atomizer tube 11. The partition 61 divides the atomizer chamber 111 into two relatively independent spaces, one for mounting the atomizer core 40 and the other for connecting the nozzle 20 to the atomizer tube 11. The partition 61 confines the atomizer core 40 within the mounting space, preventing it from shifting. An opening is provided in the partition 61 to expose the first surface 411 of the atomizer core 40, allowing the aerosol generated by the atomization of the atomizer core 40 to flow unobstructed toward the nozzle 20. The end of the oil suction element 30, located near the nozzle 20, extends into the bracket 60 and contacts the atomizer core 40, establishing fluid communication between the two elements. The partition 61 and the inner wall of the bracket 60 confine the oil suction element 30 between the bracket 60 and the atomizer tube 11, preventing it from shifting and thus ensuring a stable supply of atomized substrate.

[0046] Referring to Figure 3 , the atomizer tube 11 is provided with a mounting plate 112 and at least one rib 113. The mounting plate 112 is connected to the inner wall of the atomizer tube 11, and the fixed end of the first electrode 50 is mounted on the mounting plate 112. When assembling the atomizer assembly 100, the first electrode 50 can be inserted and fixed to the mounting plate 112, and then the atomizer core 40 can be abutted against the end of the first electrode 50 to achieve electrical connection. All of the above operations can be performed using a robotic arm, thereby automating the assembly of the atomizer assembly 100 and improving assembly efficiency.

[0047] The mounting plate 112 is provided with an air inlet 114 to allow external air to enter the atomizing chamber 111 through the air inlet 114. The draw resistance of the atomizing assembly 100 can be adjusted by adjusting the size of the air inlet 114, so that the user can experience the taste brought by different draw resistances.

[0048] The ribs 113 are strip-shaped and extend longitudinally along the atomizing tube 11. There may also be a plurality of ribs 113, which are spaced apart and connected to the inner wall of the atomizing tube 11.

[0049] As the aerosol flows toward the suction nozzle 20, as the aerosol moves away from the heating element 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 suction nozzle 20 and the inner wall of the atomizing tube 11 toward the end away from the suction nozzle 20. The condensate may cause some components of the atomizing device to fail. To recover the condensate, in one embodiment, as shown in Figure 3, the atomizing tube 11 is equipped with oil-absorbing cotton 70. The oil-absorbing cotton 70 can absorb the condensate, thereby reducing the risk of failure of some components caused by the condensate. The oil-absorbing cotton 70 abuts against the end of the rib 113 away from the suction nozzle 20, and the rib 113 can prevent the oil-absorbing cotton 70 from shifting.

[0050] Referring to Figure 3, in one embodiment, an electrode recess 131 is provided on the side of the oil cup base 13 facing away from the nozzle 20. The electrode recesses 131 are located on both sides of the end of the atomizer tube 11. A heater lead 16 is provided within the atomizer tube 11. One end of the heater lead 16 is electrically connected to the first electrode 50. The opposite end of the heater lead 16 passes through the oil cup base 13, bends toward the electrode recess 131, and is attached to the electrode recess 131. A second electrode 80 is inserted into the electrode recess 131 and is electrically connected to the heater lead 16. The heater lead 16 can be attached to the inner wall of the atomizer tube 11. The inner wall of the atomizer tube 11 can also be grooved or provided with a stopper to limit the displacement of the heater lead 16. The heater lead 16 has a certain rigidity to facilitate clamping and installation using a robotic arm. By providing the electrode sink 131 , the installation and alignment of the second electrode 80 can be facilitated to adapt to automated assembly, thereby improving assembly efficiency.

[0051] The present application provides an atomizing device. Referring to FIG8 , the atomizing device 300 may include the atomizing assembly 100, the control assembly 310, and the power supply assembly 320 as described above. The control assembly 310 may control the atomizing assembly 100 to be connected or disconnected with the power supply assembly 320 according to the suction action, so as to control the atomizing assembly 100 to heat the substrate to generate an aerosol or stop heating. Specifically, when inhaling through the mouthpiece 20, the control assembly 310 senses the negative pressure within the atomizing device 300, and the control assembly 310 controls the atomizing assembly 100 to be connected with the power supply assembly 320, and the atomizing core 40 to heat the substrate to generate an aerosol; when inhalation stops, the control assembly 310 controls the atomizing assembly 100 to be disconnected from the power supply assembly 320, and the atomizing core 40 stops heating the substrate.

[0052] The atomizer assembly provided in this application has at least the following beneficial effects:

[0053] 1. The atomizer core 40 is installed in the atomizer chamber 111 at the end of the oil cup 10 close to the suction nozzle 20. The oil storage chamber 14 is located at the end of the oil cup 10 away from the suction nozzle 20. The oil suction member 30 absorbs the atomized substrate stored in the oil storage chamber 14 to the atomizer core 40. This ensures that the atomized substrate supply rate depends only on the adsorption force of the oil suction member 30. The atomized substrate supply rate is stable, thereby ensuring the consistency of the taste of the aerosol generated by atomization.

[0054] 2. The heating element 42 is disposed on the first surface 411 of the atomizer core 40 . The first surface 411 is disposed along the axial direction of the atomizer tube 11 , so that the flow direction of the aerosol is substantially parallel to the first surface 411 , thereby reducing the flow resistance of the aerosol and the taste attenuation of the aerosol, thereby improving the taste of the aerosol.

[0055] 3. The distance d between the atomizer core 40 and the end of the nozzle 20 away from the oil cup 10 is less than 20 mm, which reduces the distance for the aerosol to reach the user's inhalation end and can comprehensively improve various indicators of the aerosol.

[0056] 4. By providing the first electrode 50, the atomizer core 40 does not need to be connected to the power supply through pins. The first electrode 50 has greater rigidity than the pins and will not bend during assembly, making it easy to align the atomizer core 40 with the first electrode 50, which is beneficial to the automated assembly of the atomizer core 40 and can improve assembly efficiency.

[0057] 5. The atomizer core 40 is installed at one end of the oil cup 10 near the suction nozzle 20. The oil suction member 30 absorbs the atomized matrix in the oil storage chamber 14 to the atomizer core 40. There is no need to set an opening at the bottom of the oil storage chamber 14 to transport the matrix to the atomizer core. This can solve the problem of the atomized matrix easily leaking from the bottom opening of the oil storage chamber 14 under gravity.

[0058] 6. When the oil suction member 30 is arranged in a columnar shape, an oil suction member mounting groove 15 is provided in the oil cup 10. The oil suction member 30 is installed in the oil suction member mounting groove 15, which can not only facilitate the installation and positioning of the oil suction member 30, but also limit the displacement of the oil suction member 30, thereby ensuring the stability of the oil supply of the oil suction member 30.

[0059] 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 atomizing tube 11. On the one hand, the atomizing tube 11 can be used to install and position the oil suction member 30 and prevent the oil suction member 30 from shifting after installation, thereby simplifying the structure of the atomizing assembly 100. On the other hand, the oil suction member 30 evenly covers the outside of the atomizing tube 11, increasing the contact surface between the oil suction member 30 and the atomizing substrate, thereby ensuring the supply rate of the atomizing substrate.
