Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] Atomizers are products that use a heating element in an atomizing component to heat a liquid matrix to produce an aerosol. They have seen widespread and rapid adoption in domestic and international markets in recent years. An atomizer contains a reservoir and a coil. The liquid matrix is ​​stored in the sealed reservoir, and the coil heats and atomizes the liquid matrix in the reservoir to generate an aerosol for the user to inhale. In conventional atomizers, the air exchange efficiency between the coil and the reservoir is low. The liquid matrix is ​​gradually absorbed and atomized by the coil, which can easily create negative pressure in the reservoir. This prevents the liquid matrix from being replenished to the coil in time, leading to dry burning of the coil, flavor degradation, or even burnt coil, negatively impacting the user experience.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an atomizing device in some embodiments of this application. Embodiments of this application provide an atomizing device 1000, including a power supply component 200 and an atomizer 100. The power supply component 200 is electrically connected to the atomizer 100 to provide electrical energy for the atomizer 100 during operation. The power supply component 200 may be a built-in battery or a charging module, transmitting power to the atomizing component via electrical connection. Metal contacts or flexible wires can be used for connection to ensure reliable connection between the power supply component 200 and the atomizer 100.

[0025] Please see Figures 2 to 4 , Figure 2 yes Figure 1 A cross-sectional schematic diagram of the atomizer in the embodiment. Figure 3 yes Figure 2 A magnified view of a portion of point A in the diagram. Figure 4 yes Figure 2 An exploded view of the atomizer in the embodiment.

[0026] The atomizer 100 includes a housing 11, a sealing seat 16, and, from the inside to the outside, an inner tube 19, a liquid reservoir 17, and an outer tube 18 arranged sequentially around the atomizing core 13. The liquid reservoir 17 is made of a porous absorbent material, such as cotton wick or fiber, and is used to store and slowly release liquid to the atomizing core 13. The housing 11 has a liquid reservoir 12 for storing the liquid matrix and an atomizing core 13 for atomizing the liquid matrix to generate an aerosol; the sealing seat 16 defines part of the boundary of the liquid reservoir 12; the liquid reservoir 12 surrounds the outer tube 18, and the outer tube 18 is provided with a guide hole 181 for connecting the liquid reservoir 17 and the liquid reservoir 12. The sealing seat 16 includes a first part 161 disposed between the inner tube 19 and the outer tube 18. The first part 161 can provide a seal between the inner tube 19 and the outer tube 18. The first part 161 is used to support the liquid storage component 17, and there is a ventilation channel 21 between the first part 161 and the liquid storage component 17 for connecting the liquid storage component 17 and the guide hole 181.

[0027] like Figure 2 and Figure 4 As shown, the inner tube 19 is provided with a through hole 191 connecting the liquid storage component 17 and the atomizing core 13, and the liquid storage component 17 covers the end of the through hole 191. In use, the liquid storage component 17 adsorbs the liquid matrix in the liquid storage chamber 12 through the guide hole 181, and then transmits the liquid matrix to the atomizing core 13 through the through hole 191 on the inner tube 19. The atomizing core 13 heats up and atomizes the liquid matrix into an aerosol for the user to inhale.

[0028] In some embodiments, outside air can flow into the liquid storage chamber 12 through the atomizing core 13, the through hole 191, and the ventilation channel 21 in sequence, or the gas in the liquid storage chamber 12 can flow to the outside through the ventilation channel 21, the through hole 191, and the atomizing core 13 in sequence.

[0029] The liquid reservoir 17 is breathable. In conventional systems, gas transmission between the atomizing core 13 and the liquid reservoir 12 requires passing through the entire liquid reservoir 17 between the inner tube 19 and the outer tube 18, which creates significant resistance to airflow. In this embodiment, the ventilation channel 21 is used to balance the air pressure between the atomizing core 13 and the liquid reservoir 12. This allows the gas between the atomizing core 13 and the liquid reservoir 12 to pass through the liquid reservoir 17 between the outer tube 18 and the inner tube 19 without having to pass through it completely. Instead, the gas only needs to pass through a portion of the liquid reservoir 17 laterally and then through the ventilation channel 21, or directly through the ventilation channel 21, to achieve gas flow between the outer tube 18 and the inner tube 19. This balances the air pressure between the atomizing core 13 and the liquid reservoir 12, ensuring that the liquid matrix in the liquid reservoir 12 is smoothly transmitted to the atomizing core 13.

[0030] In some embodiments, the outer tube 18 and the inner tube 19 can be steel pipes or fiberglass pipes, which have strong heat resistance and corrosion resistance.

[0031] Please see Figure 5 , Figure 5 yes Figure 2 A schematic diagram of the sealing seat in the embodiment. In some embodiments, a groove 211 is provided on the side of the first portion 161 facing the liquid storage component 17, and the ventilation channel 21 is at least partially formed by the groove 211. The groove 211 can be straight or curved. One end of the groove 211 communicates with the guide hole 181, thereby allowing gas to flow smoothly between the inner tube 19 and the outer tube 18 through the groove 211. In this way, the air pressure balance between the atomizing core 13 and the liquid storage chamber 12 can be achieved without passing through the entire liquid storage component 17, reducing the air resistance that occurs during the liquid matrix transmission process. The other end of the groove 211 can extend to the outer wall of the inner tube 19. In other embodiments, the other end of the groove 211 extends to at least a portion of the corresponding through hole 191 on the inner tube 19.

[0032] In some embodiments, a connecting groove (not shown) is provided on the side of the liquid storage component 17 facing the first portion 161, and the ventilation channel 21 is at least partially formed by this connecting groove. The connecting groove forms a ventilation path between the outer tube 18 and the inner tube 19, and the gas between the atomizing core 13 and the liquid storage chamber 12 can flow directly through the connecting groove, or flow through the connecting groove to a portion of the liquid storage component 17.

[0033] Please see Figure 3 and Figure 5 In some embodiments, multiple ventilation channels 21 are provided, and multiple guide holes 181 are provided, with each ventilation channel 21 communicating with at least one guide hole 181. Two, three, or four sets of ventilation channels 21 and guide holes 181 can be provided in a one-to-one correspondence; no specific limitation is made here. Multiple ventilation channels 21 are distributed at equal intervals and extend radially along the inner tube 19.

[0034] Please see Figure 3 In some embodiments, a first space 212 is provided between the first portion 161 and the outer wall of the inner tube 19, and the first space 212 communicates with the ventilation channel 21. The first portion 161 includes a first sidewall 1611 and a second sidewall 1612. The first sidewall 1611 is in close contact with the outer wall of the inner tube 19 to achieve a seal, and the second sidewall 1612 is offset outward from the first sidewall 1611, thereby forming the first space 212 between it and the outer wall of the inner tube 19.

[0035] Furthermore, the first space 212 is configured as a continuous space surrounding the outer wall of the inner tube 19 and the first portion 161. This continuous first space 212 connects multiple ventilation channels 21, forming a uniform gas flow network and ensuring more efficient pressure balance between the liquid storage chamber 12 and the atomizing core 13. Even if one ventilation channel 21 is blocked, gas flow can be maintained through the continuous first space 212 via other ventilation channels 21, preventing localized blockage from affecting overall ventilation performance.

[0036] Please continue reading. Figure 3 In some embodiments, a second space 213 is provided between the first portion 161 and the inner wall of the outer tube 18, the second space 213 connecting the ventilation channel 21 and the guide hole 181. The first portion 161 includes a third sidewall 1613 and a fourth sidewall 1614. The third sidewall 1613 is in close contact with the inner wall of the outer tube 18 to achieve a seal, and the fourth sidewall 1614 is offset toward the inner wall of the third sidewall 1613, thereby forming the second space 213 between it and the inner wall of the outer tube 18.

[0037] Furthermore, the second space 213 is configured as a continuous space surrounding the inner wall of the outer tube 18 and the first part 161. The second space 213 connects the guide hole 181 and multiple ventilation channels 21, thereby forming a uniform gas flow network to ensure a more stable gas pressure balance between the liquid storage chamber 12 and the atomizing core 13. The continuous second space 213 simplifies the assembly process, eliminating the need to align the ventilation channels 21 with the guide holes 181 one by one to achieve gas flow between the ventilation channels 21 and the guide holes 181.

[0038] Please continue reading. Figure 3In some embodiments, the liquid storage component 17 partially covers the flow guide hole 181 on the inner side of the outer tube 18. For example, the liquid storage component 17 covers 50% to 70% of the flow guide hole 181 to allow the liquid storage component 17 to effectively contact and adsorb the liquid matrix in the liquid storage chamber 12. At the same time, the airflow can flow between the inner tube 19 and the outer tube 18 through the flow guide hole 181 not covered by the liquid storage component 17 and the ventilation channel 21 to quickly balance the air pressure between the liquid storage chamber 12 and the atomizing core 13. This allows the liquid matrix to be quickly replenished from the liquid storage chamber 12 to the liquid storage component 17 through the flow guide hole 181, avoiding the dry burning phenomenon of the atomizing core 13 due to the lag in liquid matrix replenishment and effectively eliminating the burnt taste problem.

[0039] Please see Figure 2 In some embodiments, the sealing seat 16 includes a second portion 162 disposed between the outer tube 18 and the housing 11, the second portion 162 defining a portion boundary of the liquid reservoir 12, and the atomizer 100 also includes a support 14 supporting the second portion 162, the second portion 162 providing a seal between the support 14 and the housing 11.

[0040] The bracket 14 can be made of plastic or metal. The bracket 14 is fixedly connected to the housing 11 by means of snaps, riveting, etc., to support the sealing seat 16 and ensure its stable position. The sealing seat 16 can be made of easily compressible materials such as plastic or rubber to ensure sealing performance.

[0041] Please continue reading. Figure 2 In some embodiments, the second part 162 is provided with a pin slot 1621, the atomizing core 13 includes a heating element, the atomizer 100 also includes pins, one end of which is connected to the heating element and the other end is held in the pin slot 1621, the pin slot 1621 being configured to be insertable by an electrode.

[0042] Optionally, the pin slot 1621 is located on the side of the second part 162 away from the liquid storage chamber 12. A wiring channel connecting the pin slot 1621 and the atomizing core 13 is provided between the bracket 14 and the sealing seat 16. One end of the pin passes through the wiring channel and is connected to the heating element, while the other end remains in the pin slot 1621.

[0043] In some embodiments, the first portion 161 presses against the end of the reservoir 17.

[0044] The end of the liquid reservoir 17 is deformed by the first part 161, which makes the capillaries inside the liquid reservoir 17 smaller and the density larger. The smaller capillaries can increase the flow resistance of the liquid matrix. When the pore size is smaller than the critical permeation size of the liquid matrix, the surface tension effect can prevent liquid permeation. The increased density makes the internal structure of the liquid reservoir 17 more compact, blocking the channel for the liquid matrix to migrate to the ventilation channel 21, which helps to prevent the liquid matrix from leaking through the ventilation channel 21.

[0045] Please continue reading. Figure 2 In some embodiments, the atomizer 100 further includes a guide tube 20 and a seal 22. One end of the guide tube 20 has an outlet 201 for discharging aerosol, and the other end is positioned towards the reservoir 17 to guide the aerosol flow path. The seal 22 connects the guide tube 20 and the outer tube 18 and provides a seal between them to prevent leakage of the liquid matrix from the gap between the outer tube 18 and the guide tube 20. The end of the reservoir 17 facing away from the sealing seat 16 is interference-fitted by the guide tube 20 and / or the seal 22. This interference fit compresses and deforms the reservoir 17, resulting in a further reduction in internal capillary size and an increase in density, thereby increasing the flow resistance of the liquid matrix and preventing leakage.

[0046] Please see Figure 2 and Figure 4 In some embodiments, the atomizer 100 further includes an airflow channel 15 for discharging aerosol. The liquid reservoir 17 includes a first inner wall 171 and a second inner wall 172, with an inner tube 19 disposed close to the first inner wall 171. The inner tube 19, being close to the first inner wall 171, cooperates with the outer tube 18 to clamp the liquid reservoir 17. The portion of the liquid reservoir 17 clamped by the inner tube 19 and the outer tube 18 is compressed and deformed, resulting in smaller internal capillaries and increased density, which helps prevent leakage of the liquid matrix.

[0047] A portion of the airflow channel 15 is defined by a second inner wall 172. The portion of the liquid storage element 17 forming the second inner wall 172 can directly absorb the condensate flowing back from the airflow channel 15. It is understood that the portion of the liquid storage element 17 forming the second inner wall 172 has a deformable space. This portion of the liquid storage element 17 has a low density and good air permeability, which helps to allow external gas to exchange with the gas in the liquid storage chamber 12 through the liquid storage element 17, quickly balancing the internal and external air pressure of the liquid storage chamber 12.

[0048] The inner tube 19 has a through hole 191 on its wall for connecting the atomizing core 13 and the liquid storage component 17. The through hole 191 is located between the guide hole 181 and the second inner wall 172. The through hole 191 is positioned laterally opposite the atomizing core 13 so that the liquid storage component 17 can transfer the liquid matrix to the atomizing core 13 through the through hole 191. The atomizing core 13 is then located between the guide hole 181 and the second inner wall 172. The second inner wall 172, the through hole 191, and the guide hole 181 are arranged longitudinally at intervals. The through hole 191 is located above the guide hole 181 to prevent the liquid matrix in the liquid storage chamber 12 from leaking directly from the through hole 191 after passing through the guide hole 181 and the liquid storage component 17 under gravity when not in use.

[0049] In use, the liquid matrix is ​​transported to the atomizing core 13 through the guide hole 181 and the liquid storage component 17. After being heated and atomized by the atomizing core 13, it forms an aerosol and is then discharged along the partially formed airflow channel 15 defined by the second inner wall 172. Simultaneously, an air exchange path is formed between the atomizing core 13 and the guide hole 181, which helps to balance the air pressure between the atomizing core 13 and the liquid storage chamber 12, meeting the liquid supply requirements of the atomizing core 13. Furthermore, when the aerosol condenses and flows back along the airflow channel 15, it can be directly absorbed by the liquid storage component 17 through the second inner wall 172, further preventing condensate leakage.

[0050] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
