Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a power supply device and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices include a power supply unit and an atomizer. The power supply unit is electrically connected to the atomizer and supplies power to it. The atomizer has a reservoir for storing e-liquid and an atomizing coil that communicates with the liquid in the reservoir. The atomizing coil is used to heat and atomize the e-liquid to form an aerosol that the user can inhale. When used in low-temperature environments (such as outdoors in winter or at high altitudes), the e-liquid may become viscous, separate into layers, become cloudy, or even solidify due to the temperature drop. This reduces the fluidity of the e-liquid, leading to insufficient liquid supply to the atomizing coil, resulting in less aerosol generation, and even the problem of the atomizing coil burning out.

[0003] In related technologies, to address the aforementioned problems, a heating structure is incorporated within the atomizer to preheat the atomized liquid, thereby increasing its temperature, reducing its viscosity, and ultimately improving its flowability. The heating structure primarily employs two implementation methods: 1. The heating structure is linked to the atomizing core. For example, the heating structure and the atomizing core are in thermal conductive contact, allowing the heating structure to transfer the heat generated by the atomizing core during operation to the atomized liquid. Alternatively, the heating structure and the atomizing core are connected in series or parallel, allowing them to be powered on and off simultaneously, meaning they operate concurrently. However, this implementation still suffers from insufficient liquid supply during the initial preheating phase, leading to dry burning of the atomizing core. Furthermore, the impact of the heating structure on the atomizer's internal sealing must be considered when designing the heating structure, increasing structural complexity. 2. The heating structure and the atomizing core are independent. For example, the heating structure is embedded in the inner wall of the liquid reservoir, and the heating structure and the atomizing core are independently electrically connected to the power supply. However, this implementation increases the number of atomizer components, further complicating the structure. In addition, in both of the above embodiments, the heating structure is integrated into the atomizer. When the atomizer is a disposable consumable, the heating structure is difficult to recycle, thereby increasing the cost of using the atomizer. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a power supply device and an electronic atomizing device, which has a heating structure for heating the liquid storage chamber of the atomizer. The heating structure is disposed within the power supply device and is independent of the atomizer, which helps to simplify the structure of the atomizer. When the atomizer is a disposable consumable, it helps to reduce the usage cost of the atomizer.

[0051] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0056] Reference Figures 1 to 13 The power supply device according to an embodiment of this application includes a housing 100, a heating structure, and a power supply component.

[0057] Specifically, the housing 100 defines a receiving cavity 121 for housing the atomizer a, a heating structure is disposed within the housing 100, and the heating structure is at least partially exposed within the receiving cavity 121. The portion of the heating structure exposed within the receiving cavity 121 is used to heat the liquid storage cavity b of the atomizer a. A power supply component is electrically connected to the heating structure, and the power supply component is at least used to supply power to the heating structure.

[0058] In use, the power supply component supplies power to the heating structure, which in turn heats the liquid storage chamber b of atomizer a, preheating the atomized liquid. This increases the liquid temperature, reduces its viscosity, and improves its fluidity. This helps reduce aerosol generation and dry burning issues caused by insufficient liquid supply to the atomizer core c. The heating structure is located within the power supply unit and is independent of atomizer a. Compared to integrating the heating structure into atomizer a, this simplifies the structure of atomizer a and reduces its operating cost when atomizer a is a disposable consumable.

[0059] The power supply component can be located inside or outside the housing 100, and there is no limitation on this.

[0060] Specifically, the power supply component can be used to supply power only to the heating structure, or it can be used to supply power to both the heating structure and atomizer a, without limitation.

[0061] Reference Figure 5 and Figure 6 In some embodiments, one end of the receiving cavity 121 has an opening, allowing the atomizer a to be detached, in which case the atomizer a can be used as a disposable consumable.

[0062] In some embodiments, the heating structure is detachably disposed within the housing 100 to facilitate the replacement of different heating structures according to different preheating requirements, and at the same time, to facilitate the recycling of the heating structure.

[0063] In some embodiments, the portion of the heating structure exposed within the receiving cavity 121 protrudes from the inner wall of the receiving cavity 121. This portion is configured to elastically deform along the radial direction of the receiving cavity 121, allowing it to fully conform to the portion of the atomizer a located within the receiving cavity 121. This improves the heat transfer efficiency between the heating structure and the atomizer a, while also ensuring the stability and reliability of the heat transfer process between them.

[0064] It should be noted that, in some other embodiments, the portion of the heating structure exposed within the receiving cavity 121 is configured to move back and forth along the radial direction of the receiving cavity 121 in order to adjust the degree of contact between the heating structure and the atomizer a.

[0065] Reference Figure 5 and Figure 6In some embodiments, the housing 100 includes an outer shell 110 and a support 120 disposed within the outer shell 110. The support 120 has at least a portion of a receiving cavity 121 formed on it. The support 120 has a window 122 leading to the receiving cavity 121. A heating structure is disposed on the support 120. At least a portion of the heating structure is located at the window 122 and exposed to the receiving cavity 121 through the window 122. Its structure is simple and easy to implement.

[0066] Reference Figures 2 to 6 In some embodiments, the heating structure includes a flexible heating element 210 sandwiched between the outer shell 110 and the support 120. The flexible heating element 210 has a heating part 211 located at the window 122. In use, the flexible heating element 210 mainly heats up through the heating part 211, which is beneficial to reduce energy consumption compared to the case of overall heating.

[0067] Reference Figure 6 In some embodiments, at least two spaced windows 122 are provided on the support 120 around the receiving cavity 121, and a flexible heating element 210 surrounds the outer periphery of the support 120. The flexible heating element 210 has at least two heating parts 211 corresponding to each window 122, which helps to improve the preheating efficiency of the heating structure for the atomized liquid.

[0068] Specifically, the bracket 120 has windows 122 on both sides of the receiving cavity 121, and the flexible heating element 210 has two heating parts 211 that correspond one-to-one with the two windows 122.

[0069] In some embodiments, the flexible heating element 210 includes a flexible substrate 212 and a heating coating disposed on the flexible substrate 212. The portion of the flexible substrate 212 with the heating coating and located at the window 122 constitutes the heating part 211, which helps to ensure the bendability of the flexible heating element 210 so that the flexible heating element 210 can be surrounded on the outer periphery of the support 120.

[0070] Specifically, the heating coating can be made by applying an electrothermal coating.

[0071] Specifically, the flexible heating element 210 can be an FPC heating element, that is, a flexible circuit board with heating circuitry.

[0072] Reference Figures 5 to 7 In some embodiments, the heating structure further includes a heat spreader 220, which has a heat-conducting portion 221 disposed on the side of the heating element 211 facing the window 122. The heat-conducting portion 221 helps to improve the heat transfer efficiency between the heating structure and the atomizer a, while also ensuring uniform heat transfer.

[0073] Specifically, the heat spreader 220 is a metal structural component.

[0074] Reference Figures 5 to 11 In some embodiments, the heating structure further includes a heat insulation element 230, which is disposed on the side of the heating element 211 opposite to the heat conduction element 221. The heat insulation element 230 helps to prevent the heat generated by the heating element 211 during operation from being transferred to the side opposite to the heat conduction element 221, allowing the heat generated by the heating element 211 to be primarily conducted to the heat conduction element 221. This reduces heat loss and improves heat utilization, thereby reducing the power consumption of the flexible heating element 210. Since the outer shell 110 is typically a plastic structural component with limited heat resistance, the heat insulation element 230 also helps to prevent damage to the area of ​​the outer shell 110 near the heating element 211 due to overheating. Furthermore, the heat insulation element 230 also mitigates the problem of excessive heat transfer to the outer shell 110, which can cause burns to the touch.

[0075] In some embodiments, the heat insulation member 230 is an elastic silicone or rubber structure, so that the portion of the heating structure exposed in the receiving cavity 121 can elastically deform along the radial direction of the receiving cavity 121. This not only provides elastic force that causes the heat-conducting part 221 to adhere to the atomizer a after assembly, but also provides elastic force that causes the heat-conducting part 221 to adhere to the heating part 211, thereby improving heat transfer efficiency.

[0076] It should be noted that in some other embodiments, the above-mentioned elastic force can also be achieved by a spring disposed between the heat insulation member 230 and the outer shell 110, which is not limited here.

[0077] Reference Figures 7 to 11 In some embodiments, the flexible heating element 210 and the heat spreader 220 are both sheet-like, and the flexible heating element 210, the heat spreader 220 and the heat insulation element 230 are detachably connected so that any one of the flexible heating element 210, the heat spreader 220 and the heat insulation element 230 can be replaced as needed.

[0078] Reference Figures 6 to 13In some embodiments, the heat insulation component 230 includes a heat insulation body 231 and ears 232. Ears 232 are provided on opposite sides of the heat insulation body 231, and a perforation 233 is formed between each ear 232 and the heat insulation body 231. The heat spreader 220 also includes fixing portions 222. Fixing portions 222 are provided on opposite sides of the heat conduction portion 221, and each fixing portion 222 is correspondingly inserted into each perforation 233. Each fixing portion 222 is arranged correspondingly to each ear 232. The heating element 211 is sandwiched between the heat insulation body 231 and the heat conduction portion 221, thereby enabling a detachable connection between the flexible heating element 210, the heat spreader 220, and the heat insulation component 230. This structure is simple and easy to implement. Furthermore, this connection method allows for better contact between the heating element 211 and the heat conduction portion 221, resulting in better heat transfer.

[0079] It should be noted that in some other embodiments, the flexible heating element 210, the heat spreader 220 and the heat insulation element 230 can also be detachably connected by a snap-fit ​​structure or screws, which is not limited here.

[0080] Reference Figures 9 to 11 as well as Figure 13 In some embodiments, the ear portion 232 is located on opposite sides of the heat insulation body 231 along a first direction. The heat insulation body 231 is provided with a cutting groove 234 extending along the first direction, so that the heat insulation body 231 forms a first portion 2311 and a second portion 2312 that can be folded relative to the ear portion 232 in a direction intersecting the first direction. When it is necessary to assemble the flexible heating element 210 and the heat spreader 220 on the heat insulation member 230, force can be applied to drive the first portion 2311 and the second portion 2312 to fold open relative to the ear portion 232, so as to facilitate the assembly of the flexible heating element 210 and the heat spreader 220, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0081] It should be noted that the first direction mentioned above is the X direction in the attached diagram.

[0082] When the heat insulation component 230 is an elastic silicone or rubber structure, the deformation generated during the folding and opening of the first part 2311 and the second part 2312 relative to the ear 232 is elastic deformation. During the assembly of the flexible heating element 210 and the heat spreader 220, after the force is applied to drive the first part 2311 and the second part 2312 to fold and open relative to the ear 232 and place the flexible heating element 210 and the heat spreader 220, the external force applied to the first part 2311 and the second part 2312 is removed, and the first part 2311 and the second part 2312 can automatically return to the state before folding and opening relative to the ear 232 to fix the flexible heating element 210 and the heat spreader 220.

[0083] In some embodiments, the heat insulation body 231 is provided with a heat insulation structure on the side facing the heating element 211. The heat insulation structure is used to prevent the heat generated by the heating element 211 when it is working from being conducted to the heat insulation body 231. This is beneficial to further prevent the heat generated by the heating element 211 when it is working from being transferred to the side of the heating element 211 away from the heat conduction part 221. This allows the heat generated by the heating element 211 when it is working to be mainly conducted to the heat conduction part 221, thereby further reducing heat loss and improving heat utilization, which in turn helps to further reduce the power consumption of the flexible heating element 210.

[0084] Reference Figure 3 , Figure 8 , Figure 10 , Figure 12 and Figure 13 In some embodiments, the heat insulation structure includes a groove 235 disposed on the side of the heat insulation body 231 facing the heating element 211, the groove 235 and the heating element 211 enclosing a cavity d for heat insulation. On the one hand, by providing the groove 235, the contact area between the heating element 211 and the heat insulation body 231 can be reduced, which is beneficial to reducing the heat transfer efficiency between the heating element 211 and the heat insulation body 231, thereby reducing heat loss; on the other hand, the air filled in the cavity d formed by the groove 235 and the heating element 211 has a heat insulation effect, which is beneficial to further reduce heat loss.

[0085] Reference Figure 8 and Figure 12 In some embodiments, there are multiple grooves 235, which are spaced apart. Compared to the case of only one large groove 235, setting multiple smaller grooves 235 helps to enhance the structural strength of the heat insulation body 231, making the cavity d formed by the grooves 235 and the heating part 211 less likely to collapse due to compression after assembly, thereby helping to ensure the heat insulation effect of the heat insulation structure.

[0086] Reference Figure 10 and Figure 13 In some other embodiments, the number of grooves 235 is one.

[0087] Reference Figure 10 and Figure 13 In some embodiments, at least one protrusion 236 is provided in the groove 235 to abut against the heating part 211. The protrusion 236 is provided to enhance the structural strength of the heat insulation body 231, so that the cavity d formed by the groove 235 and the heating part 211 is not easy to collapse due to compression after assembly, thereby helping to ensure the heat insulation effect of the heat insulation structure.

[0088] Reference Figure 2 , Figure 3 , Figures 6 to 8 as well as Figure 11 In some embodiments, a protruding positioning post 123 is provided on the outer side wall of the bracket 120, and a first limiting hole 2221 for positioning in cooperation with the positioning post 123 is provided on the fixing part 222. The ear part 232 is provided with a clearance opening 2321 for avoiding the positioning post 123. When assembling the assembled heating structure on the outer side wall of the bracket 120, the assembled heating structure can be positioned by the cooperation between the positioning post 123 and the first limiting hole 2221, which helps to reduce the assembly difficulty and thus improve the assembly efficiency.

[0089] It should be noted that in some other embodiments, the clearance opening 2321 can also be replaced by a limiting through hole for positioning in conjunction with the positioning post 123, which is not limited here.

[0090] Based on the above embodiments, the flexible heating element 210 is sandwiched between the outer shell 110 and the support 120, and the heat spreader 220 and the heat insulation element 230 are detachably connected to the flexible heating element 210. Furthermore, the outer shell 110 is detachably sleeved on the support 120 so that the heating structure is a detachable structure disposed within the shell 100.

[0091] Specifically, the outer casing 110 and the bracket 120 can be detachably connected by a snap-fit ​​structure or by screws, which is not limited here.

[0092] Reference Figure 7 , Figure 8 and Figure 11 In some embodiments, the fixing part 222 is provided with a protruding positioning part 2222 on the side opposite to the ear part 232, and the first limiting hole 2221 extends into the interior of the positioning part 2222. The flexible heating element 210 is provided with a second limiting hole 213 for positioning in cooperation with the positioning part 2222. When assembling the heating structure, the positional relationship between the flexible heating element 210 and the heat spreader 220 can be limited by the cooperation between the positioning part 2222 and the second limiting hole 213, which helps to reduce the assembly difficulty and thus improve the assembly efficiency.

The atomizer a has a liquid storage chamber b and an atomizing core c in liquid communication with the liquid storage chamber b.

The power supply device is electrically connected to the atomizer a, and at least a portion of the liquid storage chamber b corresponds to the portion of the heating structure exposed in the receiving cavity 121.

[0094] It should be noted that the atomizer a can be detachably connected to the power supply or non-detachably connected to the power supply; this application does not impose any specific restrictions on this.
