Description

Technical Field

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

[0002] In the prior art, pins that are connected to the heating element as a whole are usually extended from both ends of the heating element, and the pins are connected to a power source. Generally speaking, the heating element and the pins of the heating element are integrally formed. In order to increase the heating power of the heating element, the heating element usually uses a material with a larger resistivity, and accordingly, the pins also have a larger resistivity. When the distance between the heating element and the power source is large, the resistance value of the pin increases, which may lead to a power mismatch between the heating element and the pin, resulting in poor explosive power of the heating element, resulting in a poor taste of the aerosol. Therefore, how to improve the taste of the aerosol has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] The present application provides an atomization assembly, which can solve the technical problem that the poor explosive power of the heating element leads to the poor taste of the aerosol.

[0004] In order to solve the above technical problems, the present application provides an atomization component, including a lower shell, a liquid-conducting medium, an atomization core and a first electrode. A liquid storage chamber and an air circuit tube are provided in the lower shell. The atomization core is arranged on one side of the air circuit tube close to the open end of the liquid storage chamber. The liquid-conducting medium is arranged in the liquid storage chamber. One end of the liquid-conducting medium extends to the bottom of the liquid storage chamber, and the other end of the liquid-conducting medium contacts the atomization core to achieve fluid communication. The liquid-conducting medium is used to transfer the atomization matrix stored in the liquid storage chamber to the atomization core. The atomization core is provided with a heating element for atomizing the atomization matrix into an aerosol; the first electrode is arranged in the air circuit tube, the first electrode is electrically connected to the heating element, the distance between the top of the first electrode and the atomization core is smaller than the distance between the top of the first electrode and the bottom of the liquid storage chamber, and the resistivity of the first electrode is smaller than the resistivity of the connection portion between the heating element and the first electrode.

[0005] The present application also provides an atomization device, comprising the atomization assembly as described above.

[0006] In the atomization assembly provided in the present application, the distance between the top of the first electrode and the atomization core is smaller than the distance between the top of the first electrode and the bottom of the liquid storage chamber, thereby reducing the resistance value between the first electrode and the heating element and reducing power loss; further, the resistivity of the first electrode is smaller than the resistivity of the connecting portion between the heating element and the first electrode, thereby reducing the resistance value of the loop and concentrating the heating power on the heating element, thereby enhancing the explosive power of the heating element and improving the taste of the aerosol.

[0023] This application provides an atomization assembly. Figure 1 to Figure 4, the atomization assembly 100 may include a lower shell 10, an upper shell 20, a liquid-conducting medium 30, an atomization core 40, and a first electrode 50. A liquid storage chamber 14 and an air circuit tube 11 are provided in the lower shell 10, and the atomization matrix is ​​stored in the liquid storage chamber 14. One end of the liquid storage chamber 14 is open, and the upper shell 20 is connected to the open end of the lower shell 10. The atomization matrix can be atomized to generate an aerosol when heated, and the aerosol reaches the end of the user's inhalation through the upper shell 20. The atomization core 40 is arranged on one side of the air circuit tube 11 close to the open end of the liquid storage chamber 14. The liquid-conducting medium 30 is arranged in the liquid storage chamber 14, one end of the liquid-conducting medium 30 extends to the bottom of the liquid storage chamber 14, and the other end of the liquid-conducting medium 30 contacts the atomization core 40 to achieve fluid communication. For the atomization assembly 100, the direction of the upper shell 20 relative to the lower shell 10 is upper, upper side, upper side or top, top, and the opposite direction is lower, lower side, lower side or bottom, bottom. The liquid-conducting medium 30 is used to transfer the atomized substrate stored in the liquid storage chamber 14 to the atomizing core 40. The atomizing core 40 is provided with a heating element 42 for atomizing the atomized substrate into an aerosol.

[0024] The first electrode 50 is disposed in the gas circuit tube 11, and the first electrode 50 is electrically connected to the heating element 42. The distance between the top of the first electrode 50 and the atomizing core 40 is smaller than the distance between the top of the first electrode 50 and the bottom of the liquid storage chamber 14, that is, the first electrode 50 is disposed close to the atomizing core 40, so that the resistance value between the first electrode 50 and the heating element 42 can be reduced to reduce power loss. Furthermore, the resistivity of the first electrode 50 is smaller than the resistivity of the connecting portion of the heating element 42 and the first electrode 50, so as to reduce the resistance value of the circuit.

[0025] In the atomizer assembly 100 provided in the present application, the distance between the top of the first electrode 50 and the atomizer core 40 is smaller than the distance between the top of the first electrode 50 and the bottom of the liquid storage chamber 14, thereby reducing the resistance value between the first electrode 50 and the heating element 42 and reducing power loss; further, the resistivity of the first electrode 50 is smaller than the resistivity of the connecting portion between the heating element 42 and the first electrode 50, thereby reducing the resistance value of the loop and concentrating the heating power on the heating element 42, thereby enhancing the explosive power of the heating element 42 and improving the taste of the aerosol.

[0026] See also Figure 5The lower shell 10 may include a lower shell side wall 12 and a lower shell bottom plate 13, the lower shell bottom plate 13 is connected to one end of the lower shell side wall 12 away from the upper shell 20, the air line tube 11 is connected to the lower shell bottom plate 13, the lower shell side wall 12, the lower shell bottom plate 13 and the air line tube 11 are arranged to form a liquid storage chamber 14, and the atomized matrix is ​​stored in the liquid storage chamber 14. The open end of the liquid storage chamber 14 is located at one end of the lower shell 10 close to the upper shell 20, and the atomizer core 40 is arranged on one side of the air line tube 11 close to the open end of the liquid storage chamber 14, and the liquid-conducting medium 30 adsorbs the atomized matrix in the liquid storage chamber 14 to the atomizer core 40, so there is no need to set an opening at the bottom of the liquid storage 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 liquid storage chamber 14 under gravity. The lower shell 10 can be made of plastic material, and the air pipe 11, the lower shell side wall 12 and the lower shell bottom plate 13 can be integrally formed.

[0027] In one embodiment, if Figure 2 As shown, the atomizer core 40 includes an oil guide 41, which is used to adsorb the atomized matrix to the heating element 42. The oil guide 41 is installed at one end of the gas line tube 11 away from the bottom of the liquid storage chamber 14, and the heating element 42 is spirally wrapped around the outer circumference of the oil guide 41. The heating element 42 is located in the gas line tube 11, and the oil guide 41 is in fluid communication with the liquid guide medium 30. The material of the heating element 42 can be one of stainless steel, nickel-chromium-aluminum alloy, nickel-chromium alloy, iron-chromium-aluminum or titanium alloy.

[0028] 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 meet 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 on the side of the open end of the air circuit tube 11 close to the liquid storage chamber 14, 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 upper shell 20 away from the lower shell 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 upper shell 20. In conventional solutions, the distance between the atomizer core 40 and the upper shell 20 is usually more than 40 mm, resulting in a decay of the taste of the aerosol when it reaches the end of the user's inhalation, and a poor user experience. Specifically, the distance d between the atomizer core 40 and the upper shell 20 can be 20 mm, 18 mm, 16 mm, 15 mm, etc., which is not specifically limited here.

[0029] The oil guide member 41 and the liquid guide medium 30 are both porous media, and the materials of the oil guide member 41 and the liquid guide medium 30 can be different or the same. In one embodiment, the oil guide member 41 and the liquid guide medium 30 are both porous fiber materials, such as one or more of fiber cotton, non-woven fabrics, linen, chemical fiber fabrics, etc., and the above materials have good lipophilicity and oil locking properties. Compared with ceramic materials, fiber materials have small pores and large porosity, so that the aerosol generated by atomization is more delicate and full of sweetness and aroma.

[0030] The oil guide member 41 and the liquid guide medium 30 can be processed separately and then connected. In one embodiment, the oil guide member 41 and the liquid guide medium 30 are integrally processed to avoid a gap between the oil guide member 41 and the liquid guide medium 30 and increase fluid resistance, so that the supply of the atomized matrix is ​​smoother.

[0031] In the prior art, the atomizer core is arranged at the lower part of the lower shell, and the atomizer matrix in the lower shell generates hydraulic pressure due to gravity, and the atomizer matrix flows to the atomizer core under the action of hydraulic pressure. The magnitude of the hydraulic pressure in the lower shell determines the supply of the atomizer matrix in the atomizer core. During the use of the atomizer device, part of the atomizer matrix is ​​atomized to generate aerosol, and the atomizer matrix gradually decreases, and the hydraulic pressure in the lower shell decreases accordingly, and the rate at which the atomizer matrix flows to the atomizer core decreases. The change in the supply rate of the atomizer matrix will cause the taste of the aerosol generated by the atomization of the atomizer core to be inconsistent, affecting the user experience. In the present application, the atomizer core 40 is installed on the upper part of the lower shell 10, and the atomizer matrix stored in the lower shell 10 is adsorbed to the atomizer core 40 through the liquid-conducting medium 30, so that the supply rate of the atomizer matrix in the atomizer core 40 depends only on the adsorption force of the liquid-conducting medium 30, and the adsorption force of the liquid-conducting medium 30 is a property of the material itself and has nothing to do with the hydraulic pressure of the atomizer matrix in the lower shell 10. The reduction of the atomizer matrix in the lower shell 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.

[0032] The liquid-conducting medium 30 can be arranged in a variety of ways. The liquid-conducting medium 30 can be columnar or cylindrical, and the liquid-conducting medium 30 is arranged on the periphery of the gas circuit tube 11. In one embodiment, as Figure 6 As shown, the liquid-conducting medium 30 is columnar, and a liquid-conducting medium installation groove 15 is provided in the lower shell 10. The liquid-conducting medium installation groove 15 extends along the longitudinal direction of the liquid storage cavity 14 to the bottom of the liquid storage cavity 14, and the liquid-conducting medium 30 is installed in the liquid-conducting medium installation groove 15. On the one hand, the liquid-conducting medium installation groove 15 can be used for positioning when assembling the liquid-conducting medium 30, which facilitates the installation of the liquid-conducting medium 30; on the other hand, after the liquid-conducting medium 30 is assembled to the liquid-conducting medium installation groove 15, the liquid-conducting medium installation groove 15 can limit the displacement of the liquid-conducting medium 30, thereby ensuring the stability of the oil supply of the liquid-conducting medium 30. The liquid-conducting medium installation groove 15 can be set on the inner wall of the lower shell side wall 12, and can also be set on the outer wall of the gas circuit pipe 11.

[0033] In another embodiment, if Figure 7 As shown, the liquid-conducting medium 30 is cylindrical, and the liquid-conducting medium 30 is sleeved on the outer periphery of the gas line tube 11, and the liquid-conducting medium 30 extends to the bottom of the liquid storage cavity 14 along the longitudinal direction of the liquid storage cavity 14. The liquid-conducting medium 30 is sleeved on the gas line tube 11, and the gas line tube 11 can be used for the installation and positioning of the liquid-conducting medium 30, and can prevent the liquid-conducting medium 30 from shifting after installation. There is no need to set up additional positioning or limiting components for the liquid-conducting medium 30, which simplifies the structure of the atomization component 100. In addition, the liquid-conducting medium 30 is evenly covered on the outside of the gas line tube 11, which increases the contact surface between the liquid-conducting medium 30 and the atomized substrate, and can ensure the supply rate of the atomized substrate.

[0034] The heating element 42 is usually in the shape of a thin and long filament, and the portion thereof connected to the first electrode 50 is also a thin filament structure. When directly connected together, the thin filament structure has low strength and is easily deformed or broken during assembly. In order to prevent the heating element 42 from being deformed or broken and to improve the stability of the electrical contact between the heating element 42 and the first electrode 50, in one embodiment, the atomizing assembly 100 further includes a supporting member 60, such as Figure 3 , Figure 8 As shown. The support member 60 is disposed between the atomizer core 40 and the first electrode 50, and the support member 60 is provided with a first through hole 61 connected to the air circuit tube 11. After the first through hole 61 is provided, the support member 60 may be in a hollow cylindrical shape. When assembling the atomizer assembly 100, the atomizer core 40 may be first mounted on the support member 60, and then the support member 60 may be assembled into the air circuit tube 11. Since the support member 60 is provided as a support body, the heating member 42 may be prevented from being deformed or broken, and the connection strength between the heating member 42 and the first electrode 50 may be effectively improved, and the stability of the electrical contact between the heating member 42 and the first electrode 50 may be improved.

[0035] The support member 60 may be made of silicone to facilitate assembly of the support member 60 into the air pipe 11. There are many ways to mount the atomizer core 40 on the support member 60. In one embodiment, Figure 3As shown, the support member 60 is provided with a pin through hole 62 and an electrode blind hole 63 extending axially along the gas circuit tube 11, and the opening of the electrode blind hole 63 is toward the bottom of the liquid storage chamber 14. The top of the first electrode 50 is inserted into the electrode blind hole 63, and the heating element 42 is provided with a heating element pin 43, which passes through the pin through hole 62, bends into the electrode blind hole 63 and electrically contacts the first electrode 50. Specifically, after the heating element pin 43 passes through the pin through hole 62, the heating element pin 43 can be fixed to the inner wall of the pin through hole 62 by gluing or the like. Since the support member 60 is arranged between the atomizing core 40 and the first electrode 50, and the support member 60 is close to the atomizing core 40, the distance between the support member 60 and the heating element 42 is relatively close, so that the length of the heating element pin 43 is short, which can improve the bending stiffness of the heating element pin 43, and the heating element pin 43 with greater stiffness supports the heating element 42 on the support member 60, which can prevent the heating element 42 from being deformed. The electrode blind hole 63 is provided to facilitate the installation and alignment of the first electrode 50 .

[0036] In another embodiment, if Fig. 9 As shown, the top of the first electrode 50 is inserted into the electrode blind hole 63, and the heater pin 43 pierces the support member 60 at the electrode blind hole 63 and is in electrical contact with the first electrode 50. It can be understood that in order to facilitate the heater pin 43 to pierce the support member 60, the thickness of the support member 60 at the electrode blind hole 63 is thinner. After the heater pin 43 pierces the support member 60, the support member 60 wrapped around the heater pin 43 can limit the displacement of the heater pin 43, thereby preventing the heater 42 from deforming. Of course, the heater pin 43 can also be glued at the piercing position of the heater pin 43 to further fix the heater pin 43.

[0037] The atomizer core 40 can be arranged along the transverse direction of the gas pipe 11. To facilitate the installation and alignment of the atomizer core 40 and the support member 60, in one embodiment, as shown in FIG. Figure 8 As shown, a first mounting hole 64 is formed at one end of the support member 60 away from the bottom of the liquid storage chamber 14 , and the atomizer core 40 is mounted in the first mounting hole 64 .

[0038] In one embodiment, if Figure 5 As shown, the end of the gas pipe 11 close to the upper shell 20 is provided with an oil guide installation hole 111, which is arranged corresponding to the first installation hole 64, and the oil guide 41 is installed in the oil guide installation hole 111, which can prevent the oil guide 41 from shifting. Figure 3 , Fig.10The atomizing assembly 100 is provided with a sealing seat 70, which is installed between the upper shell 20 and the lower shell 10, and the sealing seat 70 is connected to the upper shell 20 and the air pipe 11 respectively. The sealing seat 70 can be made of silicone material, which has good compressibility. When the sealing seat 70 is assembled between the upper shell 20 and the lower shell 10, the sealing seat 70 is compressed and deformed to seal the lower shell 10, thereby preventing leakage of the atomized matrix. The sealing seat 70 engages the oil guide member 41 in the oil guide member installation hole 111 to prevent the oil guide member 41 from shifting after installation.

[0039] The liquid-conducting medium 30 made of fiber material is relatively soft and cannot provide support for the heating element 42 surrounding the outer periphery of the oil-conducting element 41. It is easy to shift after assembly. The displacement of the liquid-conducting medium 30 may affect the supply of the atomized matrix. In addition, it is easy to deform due to squeezing during assembly, making the shape of the heating element 42 inconsistent with the design. The change in the shape of the heating element 42 will affect the taste consistency of the aerosol generated by the atomization core 40. In order to prevent the displacement of the liquid-conducting medium 30, in one embodiment, as shown in FIG. Figure 3 , Fig.11 As shown, the atomization assembly 100 is provided with a bracket 80, the bracket 80 is arranged at one end of the lower shell 10 close to the upper shell 20, the bracket 80 is accommodated in the lower shell 10, the bracket 80 is arranged around the outer periphery of the liquid-conducting medium 30, and the sealing seat 70 is covered at one end of the bracket 80 close to the upper shell 20. By providing the bracket 80, the liquid-conducting medium 30 is confined between the bracket 80 and the air circuit tube 11, which can prevent the liquid-conducting medium 30 from shifting after assembly, thereby ensuring the stability of the supply of the atomized matrix, and at the same time, it can also prevent the heating element 42 from being deformed, thereby ensuring the consistency of the taste of the aerosol generated by the atomization core 40.

[0040] See also Figure 5 , Figure 6 , a diaphragm 112 and a convex rib 113 are provided in the air circuit tube 11. The diaphragm 112 is connected to the inner wall of the air circuit tube 11, and an air inlet hole 114 is opened on the diaphragm 112. The suction resistance of the atomizer 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. One end of the first electrode 50 is inserted into the diaphragm 112. When assembling the atomizer assembly 100, the first electrode 50 can be first inserted and fixed on the diaphragm 112, and then the support 60 and the atomizer core 40 can be installed on the air circuit tube 11 to achieve electrical connection of the atomizer core 40.

[0041] The ribs 113 are strip-shaped and extend longitudinally along the gas pipe 11 . A plurality of ribs 113 are spaced apart and connected to the inner wall of the gas pipe 11 . One end of the ribs 113 is connected to a side of the diaphragm 112 away from the upper shell 20 .

[0042] As the aerosol flows toward the upper shell 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 inner wall of the upper shell 20 and the gas line tube 11 toward the end away from the upper shell 20. The condensate may cause some components of the atomization device to fail. In order to recover the condensate, in one embodiment, as Figure 3 As shown, the gas line pipe 11 contains oil-absorbing cotton 16, which can absorb condensed liquid, thereby reducing the risk of failure of some components caused by condensed liquid. The oil-absorbing cotton 16 abuts against the end of the rib 113 away from the upper shell 20, and the rib 113 can prevent the oil-absorbing cotton 16 from shifting.

[0043] See also Figure 3 In one embodiment, an electrode sink 131 is provided on one side of the lower shell bottom plate 13 away from the upper shell 20, and the electrode sink 131 is distributed on both sides of the end of the gas line tube 11. A heater lead 17 is provided in the gas line tube 11, one end of the heater lead 17 is electrically connected to the first electrode 50, and the opposite end of the heater lead 17 passes through the lower shell bottom plate 13 and then bends toward the electrode sink 131 and is attached to the electrode sink 131. A second electrode 90 is inserted in the electrode sink 131, and the second electrode 90 is electrically connected to the heater lead 17. By providing the electrode sink 131, the installation and alignment of the second electrode 90 can be facilitated, and the assembly efficiency can be improved.

[0044] This application provides an atomization device. Fig.12 , 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 upper shell 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 heats 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.

[0045] The atomizer assembly provided in this application has at least the following beneficial effects:

[0046] 1. The distance between the top of the first electrode 50 and the atomizing core 40 is smaller than the distance between the top of the first electrode 50 and the bottom of the liquid storage chamber 14, which reduces the resistance between the first electrode 50 and the heating element 42 and reduces power loss. Furthermore, the resistivity of the first electrode 50 is smaller than the resistivity of the connecting portion between the heating element 42 and the first electrode 50, which reduces the resistance of the loop and concentrates the heating power on the heating element 42, thereby enhancing the explosive power of the heating element 42 and improving the taste of the aerosol.

[0047] 2. The atomizer core 40 is installed at one end of the lower shell 10 close to the upper shell 20. The liquid-conducting medium 30 adsorbs the atomized matrix in the liquid storage chamber 14 to the atomizer core 40. Therefore, there is no need to set an opening at the bottom of the liquid storage 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 liquid storage chamber 14 under gravity.

[0048] 3. The distance d between the atomizer core 40 and the end of the upper shell 20 away from the lower shell 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.

[0049] 4. The oil guide member 41 and the liquid guide medium 30 are integrally formed to avoid a gap between the oil guide member 41 and the liquid guide medium 30 and increase fluid resistance, thereby making the supply of the atomized matrix smoother.

[0050] 5. The atomizer core 40 is installed on the upper part of the lower shell 10. The atomizer matrix stored in the lower shell 10 is adsorbed to the atomizer core 40 through the liquid-conducting medium 30, so that the supply rate of the atomizer matrix in the atomizer core 40 only depends on the adsorption force of the liquid-conducting medium 30. The reduction of the atomizer matrix in the lower shell 10 will not affect the supply rate of the atomizer matrix. The supply rate of the atomizer matrix is ​​stable, which can ensure the consistency of the taste of the aerosol generated by atomization.

[0051] 6. The atomizer assembly 100 is provided with a support member 60, and the atomizer core 40 is installed on the support member 60. The support member 60 serves as a support body to prevent the heating element 42 from being deformed or broken, effectively improves the connection strength between the heating element 42 and the first electrode 50, and improves the stability of the electrical contact between the heating element 42 and the first electrode 50.

[0052] 7. The atomization assembly 100 is provided with a bracket 80, which is arranged around the outer periphery of the liquid-conducting medium 30. The bracket 80 confines the liquid-conducting medium 30 between the bracket 80 and the gas circuit tube 11, which can prevent the liquid-conducting medium 30 from shifting after assembly, thereby ensuring the stability of the atomization matrix supply.
