Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, and in particular to a liquid storage component and an aerosol generating device. Background Technology

[0002] An aerosol generating device is a product that can transform a liquid aerosol generating matrix into an aerosol through heating or other means. In related technologies, an aerosol generating device includes an atomizing core and a liquid storage device for supplying liquid to the atomizing core. To ensure smooth liquid flow between the atomizing core and the liquid storage device, the density of the liquid storage device in contact with the atomizing core is typically 0.08 g / cm³. 3 This design limits the liquid-locking ability of the liquid storage component, which can lead to leakage. At the same time, this design also limits the liquid storage capacity of the liquid storage component, resulting in a shorter single-use time for the aerosol generating device.

[0003] Therefore, the performance of aerosol generating devices in related technologies is poor. Utility Model Content

[0004] The purpose of this application is to provide a liquid storage component and an aerosol generating device, which aims to improve the performance of the aerosol generating device.

[0005] To achieve the above objectives, the technical solution adopted in the first aspect of this application is: a liquid storage component, applied in an aerosol generating device, including a first liquid storage element and a second liquid storage element.

[0006] The first liquid reservoir has a first receiving channel for accommodating the atomizing core; the second liquid reservoir is stacked on top of the first liquid reservoir and is located away from the atomizing core; wherein the density of the second liquid reservoir is greater than the density of the first liquid reservoir.

[0007] The beneficial effects of the liquid storage component provided in the first aspect embodiment of this application are as follows: Since the density of the second liquid storage element is greater than that of the first liquid storage element, the low-density first liquid storage element has good liquid-conducting ability, and the high-density second liquid storage element has good liquid-locking ability. Because the second liquid storage element and the first liquid storage element are stacked, the first liquid storage element has a first receiving channel for accommodating the atomizing core, and the second liquid storage element is far from the atomizing core; therefore, the first liquid storage element with strong liquid-conducting ability is used to guide liquid to the atomizing core, ensuring that the aerosol generating matrix flows stably and smoothly from the first liquid storage element to the atomizing core, and the second liquid storage element with strong liquid-locking ability can improve the liquid storage rate of the liquid storage component and prevent leakage. Therefore, the liquid storage component in this application embodiment not only has good liquid-conducting ability to ensure that the aerosol generating matrix flows stably and smoothly to the atomizing core, but also has good liquid storage capacity to extend the single-use time of the aerosol generating device, thereby improving the performance of the aerosol generating device with the liquid storage component of this application embodiment.

[0008] In some embodiments, the second liquid storage device includes a plurality of stacked liquid storage units; the density of the plurality of liquid storage units gradually increases in the direction from the first liquid storage device to the second liquid storage device.

[0009] In some embodiments, the density difference between two adjacent liquid storage units ranges from 0.01 g / cm³. 3 -0.05g / cm 3 .

[0010] In some embodiments, a plurality of liquid storage units are stacked in the extending direction of the first receiving channel, and each of the plurality of liquid storage units has a sub-channel that is coaxially arranged with and sequentially connected to the first receiving channel.

[0011] In some embodiments, a plurality of liquid storage units are stacked around the axis of the first receiving channel in the radial direction of the first receiving channel.

[0012] In some embodiments, the liquid storage assembly further includes a separator and a liquid guide, the separator being disposed between the first liquid storage unit and the second liquid storage unit; the liquid guide extends through the separator, one end of the liquid guide passing through the first liquid storage unit, and the other end of the liquid guide away from the first liquid storage unit passing through the second liquid storage unit.

[0013] In some embodiments, the density of the liquid guiding component is greater than the density of the first liquid storage component, and the density of the liquid guiding component is less than the density of the second liquid storage component.

[0014] In some embodiments, in the extending direction of the first receiving channel, the second liquid storage member is stacked with the first liquid storage member, and the second liquid storage member has a second receiving channel communicating with the first receiving channel.

[0015] In some embodiments, the second liquid reservoir is sleeved around the periphery of the first liquid reservoir in the radial direction of the first receiving channel.

[0016] To achieve the above objectives, the technical solution adopted in the second aspect of this application is: an aerosol generating device, including an atomizing core and a liquid storage component as described in the first aspect of the embodiment, wherein the atomizing core is disposed in the first receiving channel.

[0017] The beneficial effects of the aerosol generating device provided in the first aspect embodiment of this application are as follows: by applying the liquid storage component of the first aspect embodiment to the aerosol generating device, the aerosol generating device not only has good liquid guiding ability so that the aerosol generating matrix can be stably and smoothly guided to the atomizing core; it also has good liquid storage capacity to extend the single use time of the aerosol generating device, thereby improving the performance of the aerosol generating device.

[0025] An aerosol generating device is a product that can transform a liquid aerosol generating matrix into an aerosol through heating or other means. In related technologies, an aerosol generating device includes an atomizing core and a liquid storage device for supplying liquid to the atomizing core. To ensure smooth liquid flow between the atomizing core and the liquid storage device, the density of the liquid storage device in contact with the atomizing core is typically 0.08 g / cm³. 3This design limits the liquid-locking ability of the liquid storage component, which can lead to leakage. At the same time, this design also limits the liquid storage capacity of the liquid storage component, resulting in a shorter single-use time for the aerosol generating device.

[0026] Therefore, the performance of aerosol generating devices in related technologies is poor.

[0027] In view of the above problems, this application provides a liquid storage component and an aerosol generating device to improve the performance of the aerosol generating device.

[0028] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0029] This application provides a liquid storage component for use in an aerosol generation device. Figure 1 This is a schematic diagram of the liquid storage component in one embodiment of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of the liquid reservoir assembly along the AA direction. The liquid reservoir assembly includes a first liquid reservoir 110 and a second liquid reservoir 120. The first liquid reservoir 110 has a first receiving channel 111 for receiving the atomizing core 200. The second liquid reservoir 120 is stacked with the first liquid reservoir 110 and is located away from the atomizing core 200. The density of the second liquid reservoir 120 is greater than the density of the first liquid reservoir 110.

[0030] In the aerosol generating device, the atomizing core 200 is located within the first receiving channel 111 and is attached to the inner wall of the first receiving channel 111, allowing the aerosol generating matrix in the first liquid storage component 110 to be transferred to the atomizing core 200. When the atomizing core 200 is working, it can heat the aerosol generating matrix, causing the temperature of the aerosol generating matrix to reach its atomization temperature, thus transforming the aerosol generating matrix from a liquid state into an inhalable aerosol.

[0031] It is understood that the second liquid reservoir 120 is stacked with the first liquid reservoir 110, that is, the second liquid reservoir 120 and the first liquid reservoir 110 are fitted together, so that the aerosol generating matrix in the first liquid reservoir 110 can flow to the second liquid reservoir 120, and the aerosol generating matrix in the second liquid reservoir 120 can flow to the first liquid reservoir 110. Since the first liquid reservoir 110 has a first receiving channel 111 for accommodating the atomizing core 200, when the atomizing core 200 located in the first receiving channel 111 is working, the aerosol generating matrix in the first liquid reservoir 110 will be consumed, causing the aerosol generating matrix in the first liquid reservoir 110 to decrease. When the aerosol generating matrix in the first liquid reservoir 110 is exhausted or about to be exhausted, the aerosol generating matrix in the second liquid reservoir 120 will flow to the first liquid reservoir 110 to replenish the aerosol generating matrix in the first liquid reservoir 110.

[0032] It is understood that the stacked arrangement of the second liquid storage component 120 and the first liquid storage component 110 can be as follows: the second liquid storage component 120 and the first liquid storage component 110 are stacked in the extending direction of the first receiving channel 111, and the second liquid storage component 120 has a second receiving channel 121 that communicates with the first receiving channel 111, so that the aerosol generated by the atomizing core 200 located in the first receiving channel 111 when it is working can flow out through the second receiving channel 121.

[0033] It is understandable that the stacked arrangement of the second liquid storage component 120 and the first liquid storage component 110 can also be: in the radial direction of the first receiving channel 111, the second liquid storage component 120 is sleeved on the periphery of the first liquid storage component 110.

[0034] The first liquid storage component 110 and the second liquid storage component 120 are generally liquid storage cotton. It is understood that the lower the density of the liquid storage cotton, the higher its porosity. Good liquid conductivity of the liquid storage cotton allows it to effectively conduct the aerosol generating matrix to the atomizing core 200, preventing insufficient liquid supply or dry burning of the atomizing core 200. Conversely, higher density of the liquid storage cotton generally means lower porosity, resulting in greater liquid conductivity resistance. This makes it difficult for the aerosol generating matrix to move between the fibers within the liquid storage cotton, leading to a slower liquid conductivity. This, in turn, gives the liquid storage cotton good liquid-locking, liquid-storing, and leak-proof capabilities.

[0035] In the liquid storage assembly provided in the first aspect embodiment of this application, since the density of the second liquid storage element 120 is greater than that of the first liquid storage element 110, the low-density first liquid storage element 110 has good liquid guiding ability, and the high-density second liquid storage element 120 has good liquid locking ability. Because the second liquid storage element 120 and the first liquid storage element 110 are stacked, with the first liquid storage element 110 having a first receiving channel 111 for accommodating the atomizing core 200 and the second liquid storage element 120 being located away from the atomizing core 200, the first liquid storage element 110, with its stronger liquid guiding ability, is used to guide liquid to the atomizing core 200, ensuring that the aerosol generating matrix is ​​stably and smoothly guided from the first liquid storage element 110 to the atomizing core 200. The second liquid storage element 120, with its stronger liquid locking ability, can improve the liquid storage rate of the liquid storage assembly and prevent leakage. Therefore, the liquid storage component in this embodiment not only has good liquid guiding ability so that the aerosol generation matrix can be stably and smoothly guided to the atomizing core 200; it also has good liquid storage ability to extend the single use time of the aerosol generation device, thereby improving the performance of the aerosol generation device with the liquid storage component in this embodiment.

[0036] In some embodiments, the second liquid storage element 120 includes a plurality of stacked liquid storage units; the density of the plurality of liquid storage units gradually increases in the direction from the first liquid storage element 110 to the second liquid storage element 120.

[0037] Understandably, when the density of the second liquid storage component 120 is too high, the pores within the second liquid storage component 120 are too small, resulting in a large liquid guiding resistance in the second liquid storage component 120. The aerosol generating matrix is ​​difficult to move between the fibers within the second liquid storage component 120, causing the liquid guiding speed of the second liquid storage component 120 to slow down, or even resulting in "poor liquid guiding". This prevents the second liquid storage component 120 from providing the aerosol generating matrix to the first liquid storage component 110 in a timely manner, leading to the dry burning of the atomizing core 200.

[0038] In the above embodiment, the density of multiple liquid storage units gradually increases in the direction from the first liquid storage unit 110 to the second liquid storage unit 120, that is, the density of the liquid storage units increases step by step in the direction away from the atomizing core 200. This can improve the liquid guiding capacity of the second liquid storage unit 120 and prevent the phenomenon of "poor liquid guiding". Furthermore, the step-by-step increase in the density of the liquid storage units in the direction away from the atomizing core 200 can also avoid the liquid "stagnation" or "backflow" at the interface caused by sudden density changes; it can also improve the stability of the structure. The multi-layered gradual density makes the interlocking between fibers in the second liquid storage unit 120 tighter, so that the second liquid storage unit 120 has good anti-collapse and anti-deformation capabilities.

[0039] Please refer to Figures 3 to 6In some embodiments, the second liquid storage device 120 includes two stacked liquid storage units. In the direction from the first liquid storage device 110 to the second liquid storage device 120, the two liquid storage units are a first liquid storage unit 122 and a second liquid storage unit 123, respectively. The density of the first liquid storage unit 122 is greater than the density of the first liquid storage device 110, and the density of the second liquid storage unit 123 is greater than the density of the second liquid storage unit 123. When the atomizing core 200 located in the first receiving channel 111 is working, the aerosol generating matrix in the first liquid storage unit 110 will be consumed, resulting in a reduction in the aerosol generating matrix in the first liquid storage unit 110. When the aerosol generating matrix in the first liquid storage unit 110 is exhausted or about to be exhausted, the aerosol generating matrix in the first liquid storage unit 122, which is closer to the first liquid storage unit 110, will flow to the first liquid storage unit 110. That is, the aerosol generating matrix in the first liquid storage unit 122 will be reduced, and the aerosol generating matrix in the second liquid storage unit 123 will be replenished to the first liquid storage unit 122.

[0040] In other embodiments, the second liquid storage device 120 includes three stacked liquid storage units. In the direction from the first liquid storage device 110 to the second liquid storage device 120, the three liquid storage units are a first liquid storage unit 122, a second liquid storage unit 123, and a third liquid storage unit. The density of the first liquid storage unit 122 is greater than the density of the first liquid storage device 110, the density of the second liquid storage unit 123 is greater than the density of the third liquid storage unit, and the density of the third liquid storage unit is greater than the density of the second liquid storage unit 123. When the atomizing core 200 located in the first receiving channel 111 is working, the aerosol generating matrix in the first liquid storage unit 110 will be consumed, resulting in a reduction in the aerosol generating matrix in the first liquid storage unit 110. When the aerosol generating matrix in the first liquid storage unit 110 is exhausted or about to be exhausted, the aerosol generating matrix in the first liquid storage unit 122, which is closer to the first liquid storage unit 110, will flow to the first liquid storage unit 110, that is, the aerosol generating matrix in the first liquid storage unit 122 will be reduced. The aerosol generating matrix in the second liquid storage unit 123 will be replenished to the first liquid storage unit 122, that is, the aerosol generating matrix in the second liquid storage unit 123 will be reduced, so that the aerosol generating matrix in the third liquid storage unit will be replenished to the second liquid storage unit 123.

[0041] It is understood that the stacked arrangement of multiple liquid storage units can be: multiple liquid storage units are stacked in the extension direction of the first receiving channel 111 (e.g.) Figure 3 and Figure 4 (As shown). The stacked arrangement of multiple liquid storage units can also be: multiple liquid storage units are stacked radially upwards in the first receiving channel 111 (e.g., Figure 5 and Figure 6 (As shown).

[0042] like Figure 3 and Figure 4 The embodiment shown can be configured to determine the number of liquid storage units and the thickness of the liquid storage units in the extension direction of the first receiving channel 111, according to the height requirements of the aerosol generating device.

[0043] like Figure 5 and Figure 6 The embodiment shown can be configured to set the number of liquid storage units and the thickness of the liquid storage units in the radial direction of the first receiving channel 111 according to the width requirements of the aerosol generating device.

[0044] In some embodiments, the density difference between two adjacent liquid storage units ranges from 0.01 g / cm³. 3 -0.05g / cm 3 .

[0045] In the above embodiment, the density difference between two adjacent liquid storage units is ≤0.05 g / cm³. 3 When the porosity difference between two adjacent liquid storage units is small, the surface tension difference between the two adjacent liquid storage units is small; the capillary pressure between the two liquid storage units is small, so that no droplet retention or backflow will occur at the interface where the two liquid storage units are in contact, thus constructing a continuous, controllable and undisturbed capillary pressure chain.

[0046] In the above embodiment, the density difference between two adjacent liquid storage units is <0.01 g / cm³. 3 This requires extremely high precision and stringent repeatability requirements for the equipment; the density difference between two adjacent liquid storage units must be >0.05 g / cm³. 3 At this time, defects such as capillary cliffs, interfacial bubbles, and hot-pressing wrinkles will significantly increase; the density difference between two adjacent liquid storage units is 0.01 g / cm³. 3 -0.05g / cm 3 The range can balance capillary continuity and process tolerance.

[0047] Optionally, the density difference between two adjacent liquid storage units is 0.02 g / cm³. 3 0.03g / cm 3 0.04g / cm 3 wait.

[0048] In the above embodiments, the density difference between two adjacent liquid storage units can be minimized as much as possible, and the thickness of the liquid storage unit can be minimized as much as possible, so as to improve the liquid locking and liquid guiding capabilities of the liquid storage assembly.

[0049] Please refer to Figure 3 and Figure 4In some embodiments, multiple liquid storage units are stacked in the extending direction of the first receiving channel 111, and each of the multiple liquid storage units has a sub-channel that is coaxially arranged with and sequentially connected to the first receiving channel 111.

[0050] In some embodiments, two liquid storage units are provided, and the two liquid storage units are stacked sequentially in the extending direction of the first receiving channel 111. The two liquid storage units are a first liquid storage unit 122 and a second liquid storage unit 123, with the first liquid storage unit 122 located between the second liquid storage unit 123 and the first liquid storage element 110. The first liquid storage unit 122 has a first sub-channel 122-1, and the second liquid storage unit 123 has a second sub-channel 123-1. The first receiving channel 111, the first sub-channel 122-1, and the second sub-channel 123-1 are sequentially connected, forming the second receiving channel 121. This allows the aerosol generated by the atomizing core 200 located in the first receiving channel 111 during operation to flow out through the first sub-channel 122-1 and the second sub-channel 123-1.

[0051] In other embodiments, three liquid storage units are provided, and the three liquid storage units are stacked sequentially in the extending direction of the first receiving channel 111. The three liquid storage units are a first liquid storage unit 122, a second liquid storage unit 123, and a third liquid storage unit. The first liquid storage unit 122 is located between the second liquid storage unit 123 and the first liquid storage element 110, and the third liquid storage unit is located on the side of the second liquid storage unit 123 opposite to the first liquid storage element 110. The first liquid storage unit 122 has a first sub-channel 122-1, the second liquid storage unit 123 has a second sub-channel 123-1, and the third liquid storage unit has a third sub-channel. The first receiving channel 111, the first sub-channel 122-1, the second sub-channel 123-1, and the third sub-channel are sequentially connected, and the first sub-channel 122-1, the second sub-channel 123-1, and the third sub-channel constitute the second receiving channel 121. This allows the aerosol generated by the atomizing core 200 located in the first receiving channel 111 to flow out through the first sub-channel 122-1, the second sub-channel 123-1, and the third sub-channel.

[0052] In other embodiments, the liquid storage units may be four, six, seven, etc. The number of liquid storage units and the thickness of the liquid storage units in the extension direction of the first receiving channel 111 can be set according to the height requirements of the aerosol generating device.

[0053] Please refer to Figure 5 and Figure 6 In some embodiments, multiple liquid storage units are stacked around the axis of the first receiving channel 111 in the radial direction of the first receiving channel 111.

[0054] In some embodiments, there are two liquid storage units, which are stacked in sequence in the radial direction of the first receiving channel 111. The two liquid storage units are a first liquid storage unit 122 and a second liquid storage unit 123. The first liquid storage unit 122 is sleeved on the periphery of the first liquid storage component 110, and the second liquid storage unit 123 is sleeved on the periphery of the first liquid storage unit 122.

[0055] In other embodiments, three liquid storage units are provided, and the three liquid storage units are stacked in sequence in the radial direction of the first receiving channel 111. The three liquid storage units are a first liquid storage unit 122, a second liquid storage unit 123 and a third liquid storage unit. The first liquid storage unit 122 is sleeved on the periphery of the first liquid storage component 110, the second liquid storage unit 123 is sleeved on the periphery of the first liquid storage unit 122, and the third liquid storage unit is sleeved on the periphery of the second liquid storage unit 123.

[0056] In other embodiments, the liquid storage units may be four, six, seven, etc. The number of liquid storage units and the thickness of the liquid storage units in the radial direction of the first receiving channel 111 can be set according to the width requirements of the aerosol generating device.

[0057] Please refer to Figures 7 to 10 In some embodiments, the liquid storage assembly further includes a separator 130 and a liquid guide 140, with the separator 130 disposed between the first liquid storage unit 110 and the second liquid storage unit 120. The liquid guide 140 passes through the separator 130, with one end of the liquid guide 140 passing through the first liquid storage unit 110 and the other end of the liquid guide 140 away from the first liquid storage unit 110 passing through the second liquid storage unit 120.

[0058] Understandably, when low-density and high-density liquid storage cotton come into contact, the aerosol-generating matrix tends to accumulate from the low-density liquid storage cotton to the high-density liquid storage cotton. This results in the high-density liquid storage cotton still containing aerosol-generating matrix even when the low-density matrix is ​​depleted. In other words, the aerosol-generating matrix in the low-density first liquid storage component 110 tends to accumulate in the high-density second liquid storage component 120. Even when the aerosol-generating matrix in the low-density first liquid storage component 110 is depleted, the high-density second liquid storage component 120 still contains aerosol-generating matrix, leading to an excessively high residual oil rate in the liquid storage assembly.

[0059] In the above embodiment, the separator 130 is disposed between the first liquid reservoir 110 and the second liquid reservoir 120, which can prevent the aerosol generating matrix in the low-density first liquid reservoir 110 from accumulating in the high-density second liquid reservoir 120. The liquid guide 140 passes through the separator 130, with one end of the liquid guide 140 penetrating the first liquid reservoir 110 and the other end of the liquid guide 140 away from the first liquid reservoir 110 penetrating the second liquid reservoir 120. The liquid guide 140 can guide the aerosol generating matrix in the second liquid reservoir 120 to the first liquid reservoir 110. This not only prevents the aerosol generating matrix in the low-density first liquid reservoir 110 from accumulating too quickly in the high-density second liquid reservoir 120, but also balances the pressure between the low-density first liquid reservoir 110 and the high-density second liquid reservoir 120.

[0060] It is understandable that when the second liquid storage unit 120 includes multiple liquid storage units, multiple separators 130 and liquid guiding members 140 are provided. Separators 130 are also provided between two adjacent liquid storage units, and liquid guiding members 140 pass through the separators 130, with both ends of the liquid guiding member 140 passing through two adjacent liquid storage units. This allows the liquid guiding member 140 to guide the aerosol generation matrix from the high-density liquid storage unit to the low-density liquid storage unit. For example... Figure 11 and Figure 12 The system comprises two liquid storage units, namely a first liquid storage unit 122 and a second liquid storage unit 123. It also comprises two separators 130 and two guides 140, namely a first separator 131 and a second separator 132, and two guides 140, namely a first guide 141 and a second guide 142. The first liquid storage unit 122 and the second liquid storage unit 123 are stacked sequentially along the extension direction of the first receiving channel 111, with the first liquid storage unit 122 located between the second liquid storage unit 123 and the first liquid storage unit 110. The first separator 131 is located between the first liquid storage unit 110 and the first liquid storage unit 122. The first guide 141 passes through the first separator 131, with one end of the first guide 141 passing through the first liquid storage unit 122 and the other end of the first guide 141, away from the first liquid storage unit 122, passing through the first liquid storage unit 110. The second separator 132 is located between the first liquid storage unit 122 and the second liquid storage unit 123. The second liquid guide 142 passes through the second separator 132. One end of the second liquid guide 142 passes through the first liquid storage unit 122, and the other end of the second liquid guide 142 away from the first liquid storage unit 122 passes through the second liquid storage unit 123.

[0061] In other embodiments, the number of liquid storage units, the number of liquid guiding components 140, and the number of separators 130 can be increased as needed.

[0062] In some embodiments, the density of the liquid guiding element 140 is greater than the density of the first liquid storage element 110, and the density of the liquid guiding element 140 is less than the density of the second liquid storage element 120.

[0063] In the above embodiments, a continuous, controllable, and undisturbed capillary pressure chain can be constructed from the second liquid storage device 120 to the liquid guiding device 140 and from the liquid guiding device 140 to the first liquid storage device 110, so that the aerosol generation matrix can flow unidirectionally from the second liquid storage device 120 to the first liquid storage device 110.

[0064] To achieve the above objectives, the technical solution adopted in the second aspect of this application is: an aerosol generating device, including an atomizing core 200 and a liquid storage component as described in the first aspect of the embodiment, wherein the atomizing core 200 is disposed in a first receiving channel 111.

[0065] The aerosol generating device also includes a housing assembly and a control assembly. The housing assembly has a liquid storage chamber and a mounting chamber. The liquid storage assembly is housed in the liquid storage chamber, and the control assembly is housed in the mounting chamber. The control assembly is electrically connected to the atomizing core 200. The control assembly provides electrical power to the atomizing core 200 and controls the operating state of the atomizing core 200 (operating power, whether it is working, etc.). When the aerosol generating matrix is ​​drawn in, the control assembly provides electrical power to the atomizing core 200 and controls the atomizing core 200 to operate, so that the atomizing core 200 can heat the aerosol generating matrix in the second liquid storage component 120 to generate aerosol.

[0066] By applying the liquid storage component of the first aspect embodiment to the aerosol generating device, the aerosol generating device not only has good liquid guiding ability so that the aerosol generating matrix can be stably and smoothly guided to the atomizing core 200, but also has good liquid storage capacity to extend the single use time of the aerosol generating device, thereby improving the performance of the aerosol generating device.
