Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to power supply components and aerosol generation devices. Background Technology

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. The atomizer generally includes a liquid reservoir and an atomizing component. The liquid reservoir is used to store the aerosol generating matrix, and the atomizing component is used to heat and atomize the aerosol generating matrix to form an aerosol that can be inhaled by the user. The battery component is used to provide electrical energy to the atomizer.

[0003] The power supply assembly also includes an airflow sensing element for sensing inhalation changes to determine whether the power supply needs to be activated to power the atomizing component. However, in existing power supply assemblies, the airflow sensing element is connected to the atomizer's air intake channel via an activation air passage. When the user inhales, condensate produced by the atomizer or leaked aerosol generating matrix can easily enter the airflow sensing element through the activation air passage. The condensate or aerosol generating matrix adheres to the surface of the airflow sensing element or enters its interior, causing it to become unresponsive or damaged, thereby affecting the atomization of the aerosol generating device. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide a power supply component and an aerosol generating device that can avoid the influence of condensate or aerosol generating matrix generated by the atomizer on the airflow sensing element.

[0005] Therefore, a first aspect of the embodiments of this application provides a power supply component, including:

[0006] First housing assembly;

[0009] The air intake passage has one end connected to the outside atmosphere and the other end connected to the start-up air passage.

[0010] A separator is disposed between the intake passage and the start-up passage. The first housing assembly and / or the start-up assembly together with the separator form a fluid passage. One end of the fluid passage is in fluid communication with the intake passage, and the other end of the fluid passage is in fluid communication with the start-up passage.

[0011] In some embodiments, one end of the fluid channel that connects to the start-up air passage is a first connecting hole; the fluid channel includes a first fluid connecting channel and a second fluid connecting channel, and one end of the first fluid channel that connects to the second fluid channel is the second connecting hole, which is located on the side of the start-up air passage away from the intake passage.

[0012] In some embodiments, the central axis of the first connecting hole and the central axis of the second connecting hole are located on the same plane.

[0013] In some embodiments, the separator is an annular protrusion surrounding the initiation airway.

[0014] In some embodiments, the mounting element is provided with a protrusion through which the activation airway passes.

[0015] In some embodiments, the protrusion is spaced apart from the inner surface of the first housing assembly.

[0016] In some embodiments, the start-up component is disposed within a first housing assembly and divides the first housing assembly into a first part and a second part, the second part including a battery cell, and the first part and the second part are not in fluid communication.

[0017] In some embodiments, the first housing assembly includes a partition structure located between the first portion and the second portion, and the activation assembly seals the partition structure.

[0018] In some embodiments, the battery assembly near the atomizer assembly is also provided with an air hole and a liquid reservoir, the lowest point of the air hole is higher than the liquid reservoir, and the air hole is connected to the air intake channel.

[0019] A second aspect of this application provides an aerosol generating apparatus, including an atomizer assembly and a power supply assembly as described in any embodiment of this application, wherein the atomizer assembly and the power supply assembly are electrically connected.

[0020] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a power supply assembly and its aerosol generating device. The power supply assembly includes: a first housing assembly; a starting assembly, which includes an airflow sensor and a mounting component, the airflow sensor being housed within the mounting component; a starting air passage with one end connected to the outside atmosphere and the other end connected to the airflow sensor; an air intake passage with one end connected to the outside atmosphere and the other end connected to the starting air passage; and a separator disposed between the air intake passage and the starting air passage. The first housing assembly and / or the starting assembly and the separator together form a fluid passage, with one end of the fluid passage fluidly connected to the air intake passage and the other end fluidly connected to the starting air passage. In this application, by providing a separator between the air intake passage and the starting air passage, condensate or aerosol generating matrix is ​​prevented from directly entering the airflow sensing element, improving the sensitivity of the airflow sensor and thus enhancing the atomization efficiency of the aerosol generating device.

[0036] like Figure 1As shown, an embodiment of this application provides an atomizing device 1 for heating and atomizing an aerosol-generating matrix to produce an aerosol for user use. The atomization method can be resistance heating, electromagnetic heating, infrared heating, laser heating, or microwave heating, and the heat transfer method can be convection, conduction, radiation, or a combination thereof. The aerosol-generating matrix includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. The aerosol-generating matrix can be in the form of a liquid, gel, paste, or solid. When the aerosol-generating matrix is ​​solid, it can be in the form of pulverized, granulated, powdered, granular, strip-shaped, or flake-shaped solid. The aerosol-generating matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes. For example, the aerosol-generating matrix may be a liquid medicine or oil, or it may be a plant-based material, such as plant roots, stems, leaves, flowers, buds, or seeds. The aerosol-generating matrix can also be a material made primarily of plants with added aerosol-forming agents and fragrance materials.

[0037] This application does not specifically limit the type of aerosol generating device 1. For example, aerosol generating device 1 may be a medical nebulizer, an air humidifier, or an electronic cigarette, etc., that requires the use of a nebulizer 10.

[0038] The shape of the electronic atomizing device 1 is not limited; for example, it can be a square column, an oval column, a racetrack-shaped column, or a cylindrical shape, etc.

[0039] like Figure 1 As shown, this application provides an aerosol generating device 1, which includes an atomizer 10 and a power supply assembly 20 according to any embodiment of this application. The power supply assembly 20 is electrically connected to the atomizer 10 and is mainly used to supply power to the atomizer 10 and control the opening and closing of the entire aerosol generating device 10. The atomizer 10 can be axially positioned above or below the power supply assembly 20, or it can be horizontally positioned on the side of the power supply assembly 20. The atomizer 10 and the power supply assembly 20 can be detachably connected by means of threaded connection, magnetic connection, snap-fit ​​connection, etc. Of course, in other embodiments, the atomizer 10 and the power supply assembly 20 can also be non-detachably combined.

[0040] In this embodiment, the power supply component includes a first housing component 210, and the atomizer 10 includes a second housing component 110. The first housing component 210 and the second housing component 110 are two separate housing components. In other embodiments, the first housing component 210 and the second housing component 110 may also be the same housing component integrally formed.

[0041] The power supply assembly 20 provided in this embodiment includes a first housing assembly 210, a start-up assembly 220, an air intake channel 230, and a separator 240. The start-up assembly 220 includes an airflow sensor 221, a mounting component 222, and a start-up air passage 223. The airflow sensor 221 is housed within the mounting component 222. One end of the start-up air passage 223 is connected to the outside atmosphere, and the other end is connected to the airflow sensor 221. One end of the air intake channel 230 is connected to the outside atmosphere, and the other end is connected to the start-up air passage 223. The separator 240 is disposed between the air intake channel 230 and the start-up air passage 223, preventing direct fluid communication between them.

[0042] See Figure 2 The starting assembly 220 includes an airflow sensor 221, a mounting component 222, and a starting air passage 223. A receiving groove 2221 is provided on the first side of the mounting component 222 away from the starting air passage 223. The receiving groove 2221 is used to receive the airflow sensor 221, so that the side of the airflow sensor 221 away from the bottom of the receiving groove 2221 is connected to the outside atmosphere. The second side of the mounting component 222 is connected to the starting air passage 223.

[0043] When a user inhales through the air outlet 120, external airflow enters the activation airway 223 through the air inlet channel 230. The air pressure within the activation airway 223 decreases, which is sensed by the airflow sensor 221. The airflow sensor 221 generates an electrical signal indicating the decreased air pressure within the activation airway 223 and transmits this signal to the control circuit 250. The control circuit 250 determines that the user has inhaled based on the decreased air pressure signal and controls the atomizer 10 to atomize and generate aerosol, thereby achieving automatic start and stop of the aerosol generating device 1. In some embodiments, the airflow sensor 221 can also control the atomization power, temperature, and other heating parameters of the atomizer according to the user's inhalation intensity to achieve different levels of atomization effects, thus improving the user experience.

[0044] The receiving groove 2221 has raised ribs on its inner wall, which form a tight connection between the receiving groove 2221 and the side wall of the airflow sensor 221. In another optional embodiment, the starting component 220 further includes a first elastic element, which is disposed between the receiving groove 2221 and the airflow sensor 221, ensuring a tight connection between them. In another optional embodiment, other sealing methods can be used between the receiving groove 2221 and the airflow sensor 221, such as spiral seals or packing seals (e.g., using materials like polytetrafluoroethylene). By sealing the mounting component 222 with the airflow sensor 221, external airflow, aerosol generation matrix, and other fluids are prevented from flowing into the power supply component through the gap between the receiving groove 2221 and the airflow sensor 221, thus improving the sensitivity of the airflow sensor.

[0045] It should be noted that fluid connectivity means that airflow / liquid can flow between the intake channel 230 and the start-up airway 223. The liquid can be an aerosol generating matrix or a condensate.

[0046] See Figure 2 The separator 240 can be disposed on the start-up assembly 220, or on the first housing assembly 210. The separator 240 can also be a structure independent of the start-up assembly 220 and the first housing assembly 210.

[0047] The separator 240 can be a flange or a groove. The shape of the separator 240 is not limited; it can be curved, such as ring, arc, semi-ring, or wavy; or it can be straight. The number of separators 240 is not limited; there can be one or more.

[0048] In this application, a separator 240 is provided between the air intake channel 230 and the start-up air channel 223. The separator 240 blocks the condensate or aerosol generation matrix, preventing the condensate or aerosol generation matrix from directly entering the airflow sensor 221 along the start-up air channel 223, thereby improving the sensitivity of the airflow sensor 221 and thus improving the atomization efficiency of the aerosol generation device 1.

[0049] Optionally, the power supply assembly 20 may also be provided with a liquid-absorbing component, which may be a liquid-absorbing cotton, liquid-absorbing paper, or desiccant, etc. The liquid-absorbing component is used to absorb liquid that leaks into the power supply assembly 20. The liquid-absorbing component can be set at any position of the power supply assembly 20, such as the start-up assembly 220, the first housing assembly 210, etc., to avoid damage to the airflow sensor 221 due to liquid leakage, thereby reducing the risk of airflow sensor 221 failure and improving the service life of airflow sensor 221.

[0050] In some embodiments, the first housing assembly 210 and / or the starting assembly 220, together with the separator 240, form a fluid channel 260. One end of the fluid channel 260 is in fluid communication with the air intake channel 230, and the other end is in fluid communication with the starting air passage 223. The separator 240 is in close contact with the inner wall of the first housing assembly 210 and / or the side of the starting assembly 220, so that the first housing assembly 210 and / or the starting assembly 220, together with the separator 240, form the fluid channel 260. All the gas passing through the air intake channel 230 is transferred to the starting air passage 223 through the fluid channel 260, thereby ensuring the intake volume transferred to the air guide channel 233.

[0051] Specifically, the separator 240 includes a first separator 241 and a second separator 242. The first separator 241 is an annular protrusion around the second side of the mounting member 222. The second separator 242 can be a curved / straight protrusion around the start-up air passage 223. For example, it can be an annular protrusion around the start-up air passage 223, an arc-shaped protrusion around half of the start-up air passage 223, or a straight protrusion between the intake passage 230 and the start-up air passage 223. The first separator 241, the second separator 242, the mounting member 222, and the first housing assembly 210 together form the first fluid passage 261; the second separator 242, the mounting member 222, and the first housing assembly 210 together form the second fluid passage 262.

[0052] In some embodiments, the end of the starting air passage 223 that communicates with the fluid passage 260 is a first connecting hole 2231, and the end of the first fluid passage 261 that communicates with the second fluid passage 262 is a second connecting hole 2621. The number of the first connecting hole 2231 and the second connecting hole 2621 is not limited; there can be one or more.

[0053] The first connecting hole 2231 and the second connecting hole 2621 can be disposed on one or more of the partition 240, the first housing assembly 210, and the starting assembly 220. Optionally, the first connecting hole 2231 can be disposed on the side wall of the second partition 242.

[0054] The air intake channel 230, the first fluid channel 261, the second connecting hole 2621, the second fluid channel 262, the first connecting hole 2231, the start-up air passage 223, and the airflow sensor 221 are sequentially fluidly connected. The first connecting hole 2231 and the second connecting hole 2621 can be rectangular, circular, or trapezoidal in shape; their shapes are not limited here, as long as the first connecting hole 2231 and the second connecting hole 2621 can transmit outside air to the start-up air passage 223.

[0055] In some embodiments, the second connecting hole 2621 is located on the side of the activation air passage 223 away from the intake passage 230. This increases the length of the fluid passage 260, delaying the entry of the aerosol generation matrix into the airflow sensor 221.

[0056] In some embodiments, when projected onto the second side of the mounting member 222, the geometric centers of the first connecting hole 2231, the second connecting hole 2621, and the air intake passage 230 are located on the same straight line. In some alternative embodiments, the geometric centers of the first connecting hole 2231, the second connecting hole 2621, and the air intake passage 230 are located on the same diameter of the first fluid passage 261.

[0057] Preferably, the first connecting hole 2231, the second connecting hole 2621, and the air inlet channel 230 are located on a straight line parallel to the central axis of the first housing assembly 210, that is, on a straight line parallel to the central axis of the aerosol generating device 1, so that the distance between the first connecting hole 2231, the second connecting hole 2621, and the air inlet channel 230 is maximized, thereby increasing the path length of the fluid channel 260 and increasing the buffer space for the aerosol generating matrix to enter the airflow sensor 221.

[0058] In some embodiments, the mounting member 222 is provided with a protrusion 2222, and the starting air passage 223 passes through the protrusion 2222, thereby creating a gap between the starting component 220 and the first housing component 210. The shape of the starting air passage 223 is not limited; it can be various shapes such as straight, curved, or labyrinthine. The end of the starting air passage 223 away from the airflow sensor 221 is a first connecting hole 2231, which can be located on the top surface or the side surface of the protrusion 2222. Regardless of the angle or direction in which the power supply component 20 is placed, the aerosol generating matrix flowing into the power supply component first fills the gap between the starting component and the housing component. Only when the liquid level of the aerosol generating matrix is ​​higher than the lowest point of the first connecting hole 2231 does the aerosol generating matrix flow into the airflow sensor 221, thus delaying the direct entry of the aerosol generating matrix into the airflow sensor 221.

[0059] In some embodiments, the protrusion 2222 may be spaced apart from the inner surface of the first housing assembly 210, i.e., there is a gap between the first connecting hole 2231 and the first housing assembly 210; a buffer groove 211 may be provided on the portion of the first housing assembly 210 corresponding to the first connecting hole 2231, or the height of the protrusion 2222 may be lower than the gap between the mounting member 222 and the first housing assembly 210 at the location of the protrusion 2222. When the power supply assembly 20 is placed axially along the first direction, the aerosol generating matrix flowing into the power supply assembly 20 first fills the first fluid channel 261; when the power supply assembly 20 is placed axially along the second direction, the aerosol generating matrix flowing into the power supply assembly 20 first fills the gap between the first connecting hole 2231 and the first housing assembly 210, and / or, the aerosol generating matrix flowing into the power supply assembly 20 first fills the first fluid channel 261.

[0060] In some embodiments, the protrusion 2222 can fit tightly against the inner surface of the first housing assembly 210, and the first connecting hole 2231 is disposed on the side of the protrusion 2222. Regardless of the angle or orientation of the power supply assembly 20, the aerosol generating matrix flowing into the power supply assembly 20 first fills the gap between the starting assembly 220 and the first housing assembly 210.

[0061] In some embodiments, the start-up component 220 is disposed within the first housing component 210 and divides the first housing component 210 into a first part and a second part, the second part including the battery cell 270, and the first part and the second part are not in fluid communication.

[0062] Specifically, the second part also includes a control circuit 250. The first part and the second part cannot be fluidly connected, which generally means that external airflow, aerosol generation matrix, and other fluids cannot flow from the first part into the second part.

[0063] In some embodiments, the first housing assembly 210 includes a partition structure 280 located between the first portion and the second portion, and the activation assembly 220 at least partially seals the partition structure 280.

[0064] Specifically, the partition component 280 includes a first through hole 212 disposed on the first housing component 210. One end of the first through hole 212 connects to the first part, and the other end connects to the second part. At least a portion of the activation component 220 is disposed in the first through hole 212 and seals the first through hole 212. The activation component 220 / first through hole 212 has raised ribs on its wall surface. The activation component 220 forms a tight connection with the inner wall of the first through hole 212 through the raised ribs, thereby sealing the first through hole 212. Alternatively, raised ribs can be directly disposed on the outer wall of the mounting component 222, which is made of elastic material, directly sealing the first through hole 212. In another optional embodiment, the partition component 280 further includes a second elastic element disposed between the first through hole 212 and the activation component 220, thereby forming a tight connection between the first through hole 212 and the activation component 220, thus creating a seal. The second elastic element can be made of silicone rubber, fluororubber, or fluorosilicone rubber.

[0065] In another optional embodiment, other sealing methods can be used between the separator 280 and the starting assembly 220, such as spiral seals, packing seals (e.g., seals made of materials like polytetrafluoroethylene). Sealing the separator 280 with the starting assembly 220 simplifies the structure, avoids adding other structural components, and prevents increased costs. After sealing, external airflow and aerosol generation matrix are prevented from flowing from the first part into the second part, improving the sensitivity of the airflow sensor. Simultaneously, it prevents the aerosol matrix from corroding structures in the second part, such as the battery cell and control circuitry, and further prevents the user from inhaling aerosols mixed with gases released from the battery cell.

[0066] See also Figure 7The first housing assembly 210 also includes a battery bracket 213, which includes a back plate 2131 and a connector 2132 disposed at one end of the back plate 2131. The connector 2132 is provided with a liquid storage tank 2133 and an air intake column 2134 at the end away from the back plate 2131. The back plate 2131 is provided with a mounting cavity 2135 for mounting an airflow sensor 221, a battery cell 270, a control circuit 250, etc. The air intake column 2134 has an air hole 2136, which is in fluid communication with the liquid storage tank 2133 and the mounting cavity 2135. After the airflow sensor 221 senses the change in airflow in the liquid storage tank 2133 through the air hole 2136, the power supply assembly 20 supplies power to the atomizer 10.

[0067] It should be noted that fluid connectivity means that airflow / liquid can flow between the area of ​​the liquid storage tank 2133 and the area of ​​the vent 2136.

[0068] In this embodiment, the battery cell 270 and the control circuit 250 are also mounted on the back plate 2131; the outer shell 214 is provided with an air intake hole 2141, and outside air flows through the air intake hole 2141 through the liquid storage tank 2133 and flows to the atomizer 10, and then the air hole 2136 can be used to detect whether the user is inhaling the aerosol generating device 1.

[0069] External airflow can communicate with the air intake channel 230 through the gap between the atomizer 10 and the power supply component 20. External airflow can also communicate with the air intake channel 230 through the through holes on the first housing component 210 and / or the second housing component 110.

[0070] The air hole 2136 is located at the end of the air inlet column 2134 away from the bottom wall of the liquid storage tank 2133, which increases the height of the air hole 2136 and prevents excessive liquid accumulation in the liquid storage tank 2133 from flowing into the air hole 2136.

[0071] In one embodiment, the air inlet on the atomizer 10 is positioned approximately opposite the center of the liquid storage tank 2133, and the position of the air inlet column 2134 is offset from the position of the air inlet of the atomizer 10 to prevent liquid from leaking into the air hole 2136.

[0072] Optional, see below Figure 7 The air hole 2136 can also be set on the side wall of the air inlet column 2134 to prevent the aerosol generation matrix on the atomizer 10 from dripping directly into the air hole 2136.

[0073] In other embodiments, the battery holder 213 may also have other shapes, such as being generally prismatic or cylindrical, and this application does not impose specific limitations on this.

[0074] Combination Figure 7The side wall of the liquid storage tank 2133 is provided with at least one first air inlet 2137, wherein at least one first air inlet 2137 is located at the position where the air intake column 2134 is embedded in the side wall of the liquid storage tank 2133. When the outside air flows into the liquid storage tank 2133 through the first air inlet 2137, it will directly pass through the air intake column 2134, which allows the air hole 2136 to detect the airflow condition more directly and efficiently.

[0075] Optionally, the air intake column 2134 can be disposed within the liquid storage tank 2133, that is, the air intake column 2134 is connected to the bottom wall of the liquid storage tank 2133, and the air intake column 2134 is spaced apart from the side wall of the liquid storage tank 2133; or, the air intake column 2134 can be partially or completely embedded in the side wall of the liquid storage tank 2133, thereby being at a greater distance from the air inlet of the atomizer 10, which can significantly reduce the risk of leakage into the air hole 2136.

[0076] The air inlet on the atomizer 10 is directly opposite the liquid reservoir 2133. The liquid reservoir 2133 is mainly used to collect the liquid leaking from the air inlet, preventing the liquid from flowing to the battery cell 270 and control circuit 250 and other devices. The external airflow flows through the liquid reservoir 2133 and to the air inlet of the atomizer 10. The water vapor and liquid leaked carried by the airflow can condense on the end face of the air inlet column 2134, and even the liquid on the end face of the battery bracket 213 is guided to the air inlet column 2134, which may lead to a high risk of the air hole 2136 being blocked.

[0077] This embodiment can significantly reduce the risk of liquid blocking the vent 2136, and avoid the airflow sensor 221 failing to sense changes in airflow, thus preventing the aerosol generating device 1 from starting normally.

[0078] It is understandable that the end of the air intake column 2134 away from the bottom wall of the liquid storage tank 2133 is designed with a chamfer. This divides the end of the air intake column 2134 away from the bottom wall of the liquid storage tank 2133 into a first end face and a flow guide slope. Compared with the design without a chamfer, the flow guide slope can reduce the platform area of ​​the end face of the air intake column 2134 away from the bottom wall of the liquid storage tank 2133, thereby reducing the amount of liquid accumulation on the air intake column 2134. At the same time, the liquid can more easily flow into the liquid storage tank 2133 through the flow guide slope, thereby reducing the risk of liquid flowing into the air hole 2136.
