[0002] Atomizing devices generally consist of an atomizer and a power supply. The atomizer is mainly used to heat the atomizing matrix to generate an aerosol, while the power supply is used to power the atomizer and control its activation. Currently, the power supply uses an airflow sensor to monitor airflow and trigger the atomizer to start. Before the atomizer starts, the entire atomizing device remains in standby mode, resulting in excessive power consumption and affecting its lifespan. Utility Model Content

[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0032] Please see Figures 1 to 5 The embodiments of this application provide a power supply device 100, which can be applied to an atomizing device. When the power supply device 100 is not activated, the entire atomizing device is not in a standby state (in the standby state, it can be directly started by the airflow sensor or the button). After the power supply device 100 is activated, it is in a standby state. This can also be understood as making it impossible for the atomizing device to be started by the airflow sensor or the button without activating the power supply device 100.
[0033] It is understandable that when the atomizing device is in standby mode, it is in a slow power consumption state even if the user does not use it, resulting in battery power decay and reducing the amount of power that the user can effectively use. By using the power supply device 100 in this embodiment, the battery 110 decay can be reduced, the battery 110 lifespan can be increased, and the user experience can be improved.
[0034] The atomizing device in this embodiment is used to heat the atomizing matrix after being powered on, so that the liquid atomizing matrix is atomized to generate an aerosol for user use. The figure shows the application of the power supply device 100 in this heating atomizing device, but it does not mean that the power supply device 100 is limited to this atomizing device. The power supply device 100 can also be used in an aerosol generating device that heats an aerosol to generate an aerosol product or in an atomizing device that uses ultrasonic atomization to generate an aerosol (or mist).
[0035] It should be noted that the term "aerosol" as used in this article can generally refer to substances that have been vaporized, atomized, sprayed or jetted, or otherwise transformed from solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.
[0036] The atomizing matrix is any suitable compound or mixture of compounds that facilitates aerosol formation during use. Atomizing matrices include, but are not limited to: polyols, such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols, such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids, such as dimethyl dodecanoate and dimethyl tetradecanoate. Nicotine may also be included. Glycerol (also known as glycerol), which has a higher boiling point than nicotine, may also be included. Propylene glycol or plant-based materials may also be included. To improve the flavor, atomization, etc., other ingredients may be added, such as edible nonionic additives like polyethylene glycol 200, polyethylene glycol 400, and sorbitol fatty acid esters, as well as various flavorings and fragrances. Flavorings and fragrances include sweeteners, cooling agents, etc.
[0037] Please see Figures 1 to 4 The power supply device 100 includes a battery 110, a circuit board 120, a fixing component 130, a conductive component 140, and a blocking component 150.
[0038] The battery 110 is configured to supply power to the atomizer 200 in the atomizing device, so that the heating element of the atomizer 200 heats up and heats the atomizing matrix to generate an aerosol after being powered on. The battery 110 can be a disposable battery or a rechargeable battery that can be used multiple times.
[0039] The circuit board 120 is electrically connected to the battery 110. The circuit board 120 can start the atomizer 200 according to the user's operation command (such as a button) or the airflow signal monitored by the airflow sensor, and can also adjust the working power of the atomizer 200. The circuit board 120 can be a flexible circuit board 120 or a rigid circuit board 120. The circuit board 120 is provided with a first contact 121 and a second contact 122 spaced apart. The first contact 121 is used to electrically connect with the atomizer 200, and the second contact 122 is used to electrically connect with the battery 110. When the first contact 121 and the second contact 122 are electrically connected, the atomizer 200 and the battery 110 are electrically connected, so that the atomizing device is in standby mode and can be directly started under the action of the airflow sensor or a button.
[0040] A fixing component 130 is disposed on one side of the circuit board 120, and the fixing component 130 and the circuit board 120 enclose a receiving space 160. The circuit board 120 is provided with a first mating structure 123, and the fixing component 130 is provided with a second mating structure 133 connected to the first mating structure 123. Through the mating connection of the first mating structure 123 and the second mating structure 133, the fixing component 130 can be fixedly disposed on one side of the circuit board 120, and a receiving space 160 that can accommodate the conductive component 140, the blocking component 150, etc. can be stably formed.
[0041] Please continue reading. Figure 2 and Figure 3 The conductive element 140 is disposed within the receiving space 160 and at least partially abuts against the cavity wall of the receiving space 160; the conductive element 140 is used to enable conduction between the battery 110 and the circuit board 120. The conductive element 140 includes a first end 141 and a second end 143 disposed opposite to each other along the direction from the first contact 121 to the second contact 122. The first end 141 is connected to the first contact 121, and the second end 143 is used to conduct electricity to the second contact 122. After the second end 143 and the second contact 122 are conductively connected, the entire atomizing device is in a standby state.
[0042] In some embodiments, the conductive element 140 is made of an elastic conductive material. The conductive element 140 can be an elastic conductive sheet made of an elastic conductive material, which has a restoring force to recover deformation under external force. For example, the conductive element 140 can be a metal spring made of stainless steel, beryllium copper, etc.
[0043] In some embodiments, the first end 141 and the first contact 121 are welded together.
[0044] The blocking element 150 is movably disposed within the receiving space 160 and is at least partially exposed outside the receiving space 160. The blocking element 150 is used to switch the atomizing device from a non-standby state to a standby state, so that the battery power does not decrease during transportation and when not in use, and is more conducive to the safety of transportation.
[0045] In some other embodiments, the blocking element 150 can also enable the atomizing device to switch back and forth between a non-standby state and a standby state.
[0046] Please see Figure 2 and Figure 3 The blocking member 150 covers the second contact 122 to block the conductive contact between the second end 143 and the second contact 122, thereby electrically disconnecting the first contact 121 and the second contact 122. At this time, the atomizing device is in a non-standby state, and at least a portion of the conducting member 140 is clamped between the blocking member 150 and the cavity wall of the receiving space 160. The conducting member 140 has an elastic restoring force close to the second contact 122. Figure 2 As shown in the left-middle figure, the blocking member 150 can be moved to expose the second contact 122. At this time, the conducting member 140, under the action of its own elastic restoring force, moves its second end 143 closer to the circuit board 120 and makes conductive contact with the second contact 122, so that the first contact 121 and the second contact 122 are electrically connected. At this time, the atomizing device is in standby mode. When using the atomizing device, the user can turn off the blocking member 150 away from the second contact 122 to make the circuit between the first contact 121 and the second contact 122 conductive and enter standby mode, such as... Figure 2 As shown in the middle right figure.
[0047] One of the first mating structure 123 and the second mating structure 133 is a mating groove, and the other is a mating protrusion, with the protrusion engaging within the mating groove. Please continue reading. Figure 3 and Figure 4 The first mating structure 123 is a mating groove that extends through the circuit board 120 along its thickness direction (perpendicular to the Y direction in the figure). The second mating structure 133 is a mating protrusion that includes an extension 1331 and a snap-fit portion 1332 disposed at the distal end of the extension 1331. The extension 1331 passes through the mating groove, and the snap-fit portion 1332 abuts against the side of the circuit board 120 (the side opposite to the side of the mounting and fixing component 130), thereby achieving a stable connection between the fixing component 130 and the circuit board 120.
[0048] In some embodiments, the mating protrusion may be made of an elastic material, which helps the snap-fit portion 1332 to abut against the circuit board 120 under the action of elastic restoring force.
[0049] It should be noted that the "far end" mentioned above refers to the end of the extension 1331 that is away from the fixing component 130. It can be understood that one end of the extension 1331 is connected to the fixing component 130, and the other end extends in a direction away from the fixing component 130 and passes through the mating groove. The far end is provided with a snap-fit part 1332, so that the fixing component 130 can be stably fixed on the circuit board 120.
[0050] In some embodiments, two of each of the first mating structure 123 and the second mating structure 133 are provided. The two first mating structures 123 are symmetrically arranged along the center line of the circuit board 120, and the two second mating structures 133 are symmetrically arranged along the center line of the fixing component 130. Of course, three, four, or more of the first mating structures 123 and the second mating structures 133 can also be provided.
[0051] In some embodiments, the conductive member 140 further includes an elastic intermediate section 142 disposed between the first end 141 and the second end 143. The elastic intermediate section 142 protrudes relative to the circuit board 120 and abuts against the cavity wall of the receiving space 160. When the blocking member 150 covers the second contact 122, the elastic intermediate section 142 has an elastic restoring force close to the second contact 122. The elastic intermediate section 142 has an arc-shaped structure to avoid excessive stress concentration that could affect the service life of the conductive member 140.
[0052] Please continue reading. Figure 3 In some embodiments, the fixing assembly 130 includes a fixing shell 131, and a second mating structure 133 is disposed on both sides of the fixing shell 131. The fixing shell 131 has a partition protrusion 134 to divide the receiving space 160 into a first cavity 161 and a second cavity 162, which are independent of each other. The first cavity 161 and the second cavity 162 are arranged sequentially along a direction from the first contact 121 to the second contact 122. The first end 141 and the first contact 121 of the conductive member 140 are disposed in the first cavity 161, and the second end 143 and the second contact 122 of the conductive member 140 are disposed in the second cavity 162. At least a portion of the elastic intermediate section 142 of the conductive member 140 abuts against the partition protrusion 134, so that when the blocking member 150 covers the second contact 122, the elastic intermediate section 142 of the conductive member 140 is sandwiched between the partition protrusion 134 and the blocking member 150 and has an elastic restoring force close to the second contact 122.
[0053] In some embodiments, the retaining shell 131 is made of an insulating material, such as hard plastic, silicone, wood, ceramic, or any non-conductive material. Preferably, the retaining shell 131 is made of an insulating rigid material, which can maintain a stable shape and prevent deformation during movement from affecting the restrictive fixation of the blocking member 150.
[0054] In some embodiments, the fixing component 130 further includes a fixing member 132, which is disposed within the second cavity 162 and abuts against the blocking member 150 for fixing the blocking member 150.
[0055] In some embodiments, the fixing member 132 is constructed of an elastic material. Because the elastic material is relatively soft, it can effectively fill the gap between the blocking member 150 and the second cavity 162 and has a high pre-compression, allowing the blocking member 150 to have an interference fit with the second cavity 162. This counteracts the effect of gravity on the blocking member 150, ensuring that the blocking member 150 does not move away from the second contact 122 due to the aforementioned factors. This allows the atomizing device to remain in a non-standby state without external force, providing the user with the freedom to switch to standby mode. Furthermore, the fixing member 132 can buffer the forces exerted on the blocking member 150 by shaking and vibration, protecting it. The shape of the fixing member 132 matches the second cavity 162, allowing the blocking member 150 to stably cover the second contact 122 without external force. The fixing member 132 can be a block with a regular shape, such as a cube, cylinder, or cuboid.
[0056] In some embodiments, the blocking element 150 is constructed to be made of an insulating material. The shape of the blocking element 150 can be strip-shaped or sheet-shaped, without much limitation. For example, the blocking element 150 can be a PET insulating sheet.
[0057] In some embodiments, the atomizing device further includes a housing 300, with the power supply device 100 and the atomizer 200 both disposed within the housing 300. The housing 300 has a disassembly / removal opening 310 extending along the movement direction of the blocking member 150. At least a portion of the blocking member 150 extends through the disassembly / removal opening 310 and is disposed outside the housing 300. The blocking member 150 includes a blocking portion 151 and an exposed portion 152 connected to each other. The blocking portion 151 can cover the second contact 122, and the exposed portion 152 can drive the blocking portion 151 to expose the second contact 122. The exposed portion 152 is disposed outside the housing 300 via the disassembly / removal opening 310 and can bend and extend in a direction perpendicular to the movement direction of the blocking member 150, abutting against the housing 300. (See also...) Figure 5 The bottom of the outer casing 300 (according to usage habits, the end away from the air outlet 320 is the bottom) is provided with a disassembly port 310. The blocking member 150 can move along the axial direction Y of the outer casing, bending the exposed part 152 in a direction perpendicular to the axial direction Y of the outer casing 300 and abutting against the outer casing 300. This helps with the packaging of the atomizing device during transportation and also helps with the placement of the atomizing device (bottom in contact with the placement surface).
[0058] In some specific embodiments, the blocking member 150 is constructed as an integrally formed structure including a blocking portion 151 and an exposed portion 152. The blocking member 150 is made of an elastic soft material, allowing the exposed portion 152 to deform under external force, bending along the axial direction Y perpendicular to the outer shell 300 and abutting against the outer shell 300. In other specific embodiments, the blocking member 150 is constructed as a separate structure including a blocking portion 151 and an exposed portion 152. The blocking portion 151 and the exposed portion 152 can be hinged, allowing the exposed portion 152 to rotate freely relative to the blocking portion 151. It can rotate to extend in the same direction as the blocking portion 151 to pull the blocking portion 151 out to expose the second contact 122, or it can rotate to abut against the outer shell 300 in the axial direction Y perpendicular to the outer shell 300, facilitating the placement and transportation of the atomizing device.
[0059] In some embodiments, the outer casing 300 is provided with an external power supply mounting port 330, and the circuit board 120 is also provided with a connector 124. The connector 124 is disposed in the external power supply mounting port 330 and is configured to be electrically connected to a Type-C connector (not shown in the figure). After connecting an external power source with a Type-C connector, the battery 110 can be charged, thereby improving the battery 110's battery life and effectively extending the lifespan of the atomizing device. In some specific embodiments, the aforementioned disassembly port 310 is located inside the external power supply mounting port 330, that is, it coincides with the external power supply mounting port 330, reducing the processing steps of the outer casing 300.
[0060] Embodiments of this application also provide an atomizing device, including a housing 300, an atomizer 200, and a power supply device 100. The housing 300 can be understood as an assembly of multiple components, and corresponding spaces and assembly structures can be formed within the housing 300 to accommodate the atomizer 200 and the power supply device 100. The housing 300 also facilitates the overall carrying or movement of the atomizer 200 and the power supply device 100.
[0061] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
