Description

Technical Field

[0002] Atomizing devices are used to heat and atomize a substrate into a usable aerosol. Inside, there is an atomizing core that needs to be in constant contact with the substrate for heating and atomization. However, when storage or transportation causes pressure or temperature changes between the atomizing device and the external environment, creating a pressure difference, the atomizing substrate will leak through the atomizing core under pressure exceeding the external pressure. This leakage significantly impacts user experience and operating costs. Utility Model Content

[0054] 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.

[0055] 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.

[0056] 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).

[0057] In related technologies, an atomizing device consists of a liquid storage chamber and an atomizing chamber. The liquid storage chamber stores the atomizing matrix and can supply the atomizing matrix to the atomizing chamber. An atomizing core is installed in the atomizing chamber. The atomizing core serves as the aerosol generating part of the atomizing device and can generate high temperatures to heat and atomize the atomizing matrix into an aerosol. The atomizing core is usually immersed in the atomizing matrix or wrapped by a liquid storage component containing the atomizing matrix. The atomizing matrix is ​​transferred to the heating element inside the atomizing core through a liquid inlet hole provided by the liquid guiding component inside the atomizing core, relying on the capillary force provided by the liquid guiding component inside the atomizing core. When energized, the heating element generates high temperatures to heat the atomizing matrix.

[0058] Throughout the entire lifespan of an atomizing device, leakage remains a persistent problem for users, significantly impacting user experience and operating costs. To address this issue, a coil-oil separation structure is typically incorporated into the atomizing device. This structure keeps the atomizing matrix separate from the coil, preventing the coil from contacting the atomizing matrix. Common coil-oil separation methods involve manual, one-time isolation via mechanical structures or repeated isolation. By applying external force, the atomizing device can move axially or radially through the isolation components, separating or connecting the atomizing matrix and the coil.

[0059] To address the aforementioned issues, this application provides an atomizing device that supplies a preset amount of atomizing matrix to the atomizing chamber when the number of suctions reaches a threshold, thereby preventing excessive atomizing matrix from remaining in the atomizing chamber and reducing the risk of leakage.

[0060] See Figures 1-4 As shown, the atomizing device provided in this application includes a liquid storage chamber 10, an atomizing chamber 20, and a control valve 30.

[0061] The liquid storage chamber 10 is configured to store the atomizing matrix, and the liquid storage chamber 10 is provided with a liquid outlet 111. The liquid storage chamber 10 has a liquid storage cavity 11 inside, and the liquid outlet 111 is provided through the wall of the liquid storage chamber 10, and the liquid outlet 111 is connected to the liquid storage cavity 11.

[0062] The atomizing chamber 20 is located at one end of the liquid storage chamber 10. The atomizing chamber 20 is configured to receive the atomizing matrix. In other words, the liquid storage chamber 10 can provide the atomizing matrix to the atomizing chamber 20, and the atomizing chamber 20 receives the atomizing matrix provided by the liquid storage chamber 10.

[0063] The atomizing chamber 20 has liquid guiding holes 211 on its walls. The atomizing chamber 20 has an atomizing cavity 21 inside. The liquid guiding holes 211 on the walls of the atomizing chamber 20 are connected to the atomizing cavity 21. The atomizing matrix stored in the liquid storage chamber 10 can enter the atomizing cavity 21 through the liquid outlet 111 and the liquid guiding holes 211 in sequence and be received by the atomizing chamber 20. The received atomizing matrix is ​​temporarily stored in the atomizing cavity 21.

[0064] The atomizing device provided in this embodiment also includes an atomizing component 90, which is disposed in an atomizing cavity 21 inside the atomizing chamber 20. The atomizing matrix temporarily stored in the atomizing cavity 21 is transferred to the atomizing component 90, which is configured to atomize the atomizing matrix to generate an aerosol.

[0065] The flow control valve 30 is located at one end of the liquid storage chamber 10 near the atomizing chamber 20. The flow control valve 30 has an inlet port 31 and an outlet port 32. The inlet port 31 is configured to communicate with the outlet hole 111, and the outlet port 32 is configured to communicate with the guide hole 211.

[0066] The control valve 30 is used to control the connection or disconnection of the inlet port 31 and the outlet port 32. The atomizing matrix is ​​usually in liquid form. When the control valve 30 controls the connection between the inlet port 31 and the outlet port 32, the atomizing matrix stored in the storage chamber 10 enters the atomizing cavity 21 through the outlet hole 111, the inlet port 31, the outlet port 32, and the guide hole 211 in sequence under its own gravity, thus providing the atomizing matrix to the storage chamber 20. When the control valve 30 controls the connection between the inlet port 31 and the outlet port 32, the supply of atomizing matrix to the storage chamber 20 stops.

[0067] In this application, combined with Figure 3 , Figure 6 and Figure 8 As shown, the centerline of the liquid inlet port 31 is coaxial with the centerline of the liquid outlet port 32, which can shorten the transmission path of the atomized matrix, avoid the phenomenon of liquid hanging, and improve the accuracy of atomized matrix delivery.

[0068] See Figures 2-4 As shown, the liquid guiding hole 211 is located on the wall of the atomizing chamber 20 at the end away from the liquid storage chamber 10, which is equivalent to setting the liquid guiding hole 211 at the bottom of the atomizing chamber 20, ensuring that the atomizing matrix can completely enter the atomizing cavity 21 through the liquid guiding hole 211.

[0069] For easy installation of the control valve 30, please refer to [reference needed]. Figures 2-4 As shown, the atomizing device provided in this application also includes an installation chamber 40, which is disposed on the periphery of the atomizing chamber 20 and is used to accommodate the conduction valve 30.

[0070] In some embodiments, the atomizing chamber 20 and the mounting chamber 40 are both located below the liquid storage chamber 10, and the atomizing chamber 20 and the mounting chamber 40 can be independent structures. Of course, the atomizing chamber 20 and the mounting chamber 40 can also be an integrated structure, which can be selected according to actual needs.

[0071] In this embodiment, when the liquid outlet port 32 is connected to the liquid guide hole 211, to avoid the problem of atomized matrix leakage due to the gap between the two, see [reference needed]. Figure 3 and Figure 4 As shown, the atomizing device provided in this embodiment also includes a first sealing element 50, which is disposed within the mounting chamber 40 and forms a liquid outlet channel 51. The liquid outlet channel 51 is used to at least partially accommodate the liquid outlet port 32. In one embodiment, the liquid outlet port 32 is a tubular structure protruding from the outer periphery of the conduction valve 30. At least a portion of the tubular liquid outlet port 32 is sealed and inserted into the liquid outlet channel 51, thereby accommodating at least a portion of the liquid outlet port 32 within the liquid outlet channel 51. This allows the outer periphery of the liquid outlet port 32 accommodated in the liquid outlet channel 51 to be tightly fitted against the channel wall of the liquid outlet channel 51, achieving a sealing effect. The bottom wall of the mounting chamber 40 and the end face of the first sealing element 50 facing the bottom wall of the mounting chamber 40 are configured to be opposite each other to form a transition cavity 52. ​​The transition cavity 52 communicates with the liquid guide hole 211 and the liquid outlet channel 51, allowing the liquid outlet port 32 to communicate with the liquid guide hole 211 through the transition cavity 52.

[0072] See Figure 9As shown, the first sealing member 50 has a relief groove 521 at one end facing the bottom wall of the installation chamber 40. The first sealing member 50 is installed in close contact with the bottom wall of the installation chamber 40. The groove wall of the relief groove 521 and the bottom wall of the installation chamber 40 together define the transition cavity 52. ​​The relief groove 521 is equivalent to a notch structure formed on the end of the first sealing member 50 facing the bottom wall of the installation chamber 40. This notch structure is also connected to the liquid outlet channel 51. After the groove wall of the relief groove 521 and the bottom wall of the installation chamber 40 define the transition cavity 52, the liquid outlet port 32 can be indirectly connected to the liquid guide hole 211.

[0073] When the inlet port 31 is connected to the outlet port 111, it is necessary to seal the gap between them to prevent leakage of the atomizing matrix caused by a gap between them. See Figure 3 and Figure 4 As shown, the atomizing device provided in this embodiment also includes a second sealing member 60. The second sealing member 60 is disposed inside the liquid storage chamber 10, dividing the space inside the liquid storage chamber 10 into upper and lower parts. The upper space is the liquid storage cavity 11, and the lower space is where the atomizing chamber 20 and the mounting chamber 40 are installed. The second sealing member 60 is used to seal the liquid storage chamber 10 to form the liquid storage cavity 11.

[0074] The liquid outlet 111 is formed through the second seal 60, and the liquid inlet 31 is at least partially housed in the liquid outlet 111. Similarly, the liquid inlet 31 can also be a tubular structure protruding from the outer periphery of the control valve 30. At least part of the tubular liquid inlet 31 is inserted into the liquid outlet 111, so that the outer periphery of the tubular liquid inlet 31 fits and seals with the hole wall of the liquid outlet 111, preventing the atomized matrix stored in the liquid storage tank 10 from leaking through the gap between the liquid inlet 31 and the liquid outlet 111.

[0075] In this embodiment, the atomizing chamber 20 and the mounting chamber 40 are an integral structure. Figure 10 and Figure 11 As shown, a bracket 41 is also provided below the second seal 60. One end of the bracket 41 is provided with an atomizing groove 411 and an installation groove 412, which seals one end of the bracket 41 to the second seal 60, so that the second seal 60 and the atomizing groove 411 form an atomizing chamber 20, and the installation groove 412 and the second seal 60 form an installation chamber 40, forming an integrated atomizing chamber 20 and an installation chamber 40, which is convenient for product manufacturing.

[0076] See Figure 2As shown, the liquid storage chamber 10 is provided with a through-hole air outlet channel 112, the atomizing component 90 is provided with a through-hole atomizing channel 921, and the atomizing chamber 20 is also provided with an air inlet channel 22. One end of the air inlet channel 22 is connected to the outside, one end of the atomizing channel 921 is connected to the air outlet channel 112, and the other end of the atomizing channel 921 is connected to the other end of the air inlet channel 22. In actual use, outside air can enter the atomizing channel 921 through the air inlet channel 22, and the resulting airflow can output the aerosol generated by the atomizing component 90 on the atomizing matrix through the air outlet channel 12.

[0077] In this embodiment, the atomizing component 90 includes an atomizing tube 91, a liquid guiding component 92, and a heating component 93. The atomizing tube 91 is disposed inside the atomizing space 21, and the liquid guiding component 92 is disposed inside the atomizing tube 91. The liquid guiding component 92 is a hollow cylindrical structure with open ends, forming an atomizing channel 921 inside. The heating component 93 is attached to the channel wall of the atomizing channel 921, which penetrates the atomizing chamber 20. The liquid guiding component 92 is typically made of fiber cotton. The atomizing tube 91 also has liquid passage holes (not shown in the figure). The atomizing matrix temporarily stored in the atomizing space 21 can be absorbed by the liquid guiding component 92 through the liquid passage holes by capillary force, and the absorbed atomizing matrix is ​​transferred to the heating component 93. The heating component 93 can then heat the matrix to atomize it and generate an aerosol. The generated aerosol is output through the air outlet channel 112 along with the external air entering through the air inlet channel 22.

[0078] In one embodiment, the atomizing device provided in this application is applied to an electronic cigarette. The atomizing matrix is ​​an e-liquid product. The user needs to use the atomizing device by inhaling. Therefore, a mouthpiece 12 is also provided on the liquid storage tank 10. The mouthpiece 12 has a mouthpiece opening 121, and an air outlet channel 112 passes through the mouthpiece opening 121. When the user uses the device, he inhales through the mouthpiece 12, which creates a negative pressure in the interconnected air outlet channel 112, atomizing channel 921, and air inlet channel 22, allowing external air to enter through the air inlet channel 22.

[0079] It is easy to understand that the guide valve 30 in this application can be triggered when the user performs suction through the nozzle 12 to achieve the function of automatic start-up, which is convenient for the user.

[0080] See Figure 7 As shown, the atomizing device provided in this embodiment also includes an airflow sensor 70. The airflow sensor 70 is used to detect suction action or air pressure change to generate a drive signal. The conduction valve 30 is configured to respond to the drive signal to control the opening or closing of the liquid inlet port 31 and the liquid outlet port 32.

[0081] External gas enters through the air intake channel 22. Pressure changes within the air intake channel 22 are reflected in the gas pressure. Each suction action by the user generates a pressure change; therefore, detecting this pressure change is equivalent to detecting the suction action. When the airflow sensor 70 detects a suction action or a pressure change, it generates a drive signal. Under the control of this drive signal, the open valve 30 connects the inlet port 31 to the outlet port 32. Conversely, when the airflow sensor 70 does not detect a suction action or a pressure change, it does not generate a drive signal, and the open valve 30 disconnects the inlet port 31 from the outlet port 32.

[0082] In some embodiments, when a user performs a suction action, if the airflow sensor 70 generates a drive signal each time it detects a suction action or a change in air pressure, then the liquid storage chamber 10 provides atomizing matrix to the atomizing chamber 20 once for each suction action. This frequent activation of the on-state valve 30 not only results in an excessive supply of atomizing matrix but also increases the power consumption of the atomizing device, affecting the product's battery life. Instead, after storing a certain amount of atomizing matrix in the atomizing chamber 20, the user can perform a preset number of suction actions. Therefore, the on-state valve 30 can be set to activate once after a preset number of suction actions. See also... Figure 7 As shown, the atomizing device provided in this embodiment also includes a suction count monitoring unit 80, which is used to detect the number of suction actions based on the drive signal. The on-state valve 30 is configured to switch the state of the inlet port 31 and the outlet port 32 to open when the number of suction actions reaches a preset threshold.

[0083] In one embodiment, the suction count monitoring unit 80 is used to detect the cumulative suction time based on the drive signal. For example, the start time of the airflow sensor is recorded by the timer built into the suction count monitoring unit 80. Both the cumulative suction time and the number of suctions are indicators reflecting the remaining amount of atomizing matrix in the atomizing chamber. The accuracy of the two varies slightly on different types of atomizing devices.

[0084] In other words, the suction count monitoring unit 80 monitors the number of suction actions after the inlet port 31 and outlet port 32 are last connected by the control valve 30. When the number of suction actions reaches a preset threshold, the control valve 30 connects the inlet port 31 and outlet port 32 again. For example, if the preset threshold for the number of suction actions is 100-200 times, then after this number of suction actions, the control valve 30 will reconnect the inlet port 31 and outlet port 32 to provide atomizing matrix to the atomizing chamber 20 again.

[0085] See Figure 8As shown, the control valve 30 includes a valve body 33, a valve core 34, an electromagnetic coil 35, and an elastic element 36. The valve body 33 has a sliding channel 331 and a connecting channel 332 that are interconnected inside. The inlet port 31 and the outlet port 32 are both located on the valve body 33. The two ends of the connecting channel 332 are connected to the inlet port 31 and the outlet port 32, respectively. The connecting channel 332 has an opening and closing part 3321. The sliding channel 331 extends to the opening and closing part 3321. The electromagnetic coil 35 is arranged around the periphery of the sliding channel 331. The valve core 34 is slidably arranged in the sliding channel 331. The elastic element 36 is connected between the valve body 32 and the valve core 34.

[0086] In the initial state, the elastic element 36 applies elastic potential energy to the valve core 34, causing the valve core 34 to block the opening and closing part 3321, thereby cutting off the communication channel 332 and disconnecting the inlet port 31 and the outlet port 32. When the electromagnetic coil 35 is energized, the valve core 34 overcomes the elastic potential energy to disengage from the opening and closing part 3321, thereby opening the communication channel 332 and making the inlet port 31 and the outlet port 32 connected.

[0087] See Figure 2 and Figure 3 As shown, the atomizing device provided in this embodiment also includes a power supply unit 100. The power supply unit 100 is electrically connected to the conduction valve 30, the atomizing component 90, the airflow sensor 70, and the suction count monitoring unit 80, and can provide power to the conduction valve 30, the atomizing component 90, the airflow sensor 70, and the suction count monitoring unit 80 to ensure the operation of the device. In this embodiment, as... Figure 11 As shown, the other end of the bracket 41 is provided with a power supply mounting cavity 413, and the power supply unit 100 is installed in the power supply mounting cavity 413.

[0088] Under the influence of electrical energy supplied by the power supply unit 100, the electromagnetic coil 35 generates a magnetic field. The valve core 34, made of a high-permeability material, overcomes the second elastic potential energy of the elastic element 36 under the action of the magnetic field, moving along the sliding channel 331 in a direction away from the opening and closing part 3321, and opening the opening and closing part 3321, thereby opening the connecting channel 332 to connect the inlet port 31 and the outlet port 32. Conversely, when the supply of electrical energy to the electromagnetic coil 35 is stopped, the elastic element 36 provides elastic potential energy to the valve core 34, causing it to move along the sliding channel 331 in a direction toward the opening and closing part 3321, so that the valve core 34 blocks the opening and closing part 3321, thereby cutting off the connecting channel 332 and disconnecting the inlet port 31 and the outlet port 32.

[0089] In this embodiment, when the electromagnetic coil 35, under the action of the electrical energy provided by the power supply unit 100, causes the valve core 34 to open the opening / closing part 3321 due to the second elastic potential energy of the customer elastic element 36, the open connection channel connects the liquid inlet port 31 and the liquid outlet port 32. The atomizing matrix then enters the atomizing chamber 20 from the liquid storage chamber 10 under its own gravity. During this process, the air inside the atomizing chamber 20 is compressed, resulting in a slow liquid flow rate. See [link to relevant documentation] for details. Figure 6 and Figure 8 As shown, the conduction valve 30 provided in this embodiment also includes a one-way air intake structure 37. The one-way air intake structure 37 is connected to the communication channel 332 inside the valve body 33. The one-way air intake structure 37 can be a one-way valve, which is connected to the outside air. It allows the outside air to flow into the liquid storage tank 10 in one direction through the one-way valve and the communication channel 331, so as to balance the air pressure inside the liquid storage tank 10 and the outside space and ensure the liquid discharge speed of the atomized matrix.

[0090] See Figure 6 , Figure 10 and Figure 11 As shown, in some embodiments, the control valve 30 is also provided with a lead wire, through which the electromagnetic coil 35 is electrically connected to the power supply unit 100. For ease of installation, a lead wire channel 414 is also provided on the bracket 41, which passes through one end of the bracket 41 and the other end. The channel wall of the lead wire channel 414 is provided with a lead wire hole 415, which connects the lead wire channel 414 and the mounting groove 412. In this way, the lead wire 37 can be led out from the lead wire channel 414 through the lead wire hole 415 to the power supply mounting cavity 413 at the other end of the bracket 41 for electrical connection with the power supply unit 100.

[0091] See Figures 1-3 , Figure 5 As shown, in order to improve the service life of this atomizing device, atomizing matrix can be added to the liquid storage chamber 10. Therefore, a liquid replenishment hole 13 is also provided on the wall of the liquid storage chamber 10, and a sealing component 14 is also provided at the liquid replenishment hole 13. The sealing component 14 is used to block or open the liquid replenishment hole 13. When the liquid replenishment hole 13 is open, the atomizing matrix can be added to the interior of the liquid storage chamber 10 through the liquid replenishment hole 13. When the liquid replenishment hole 13 is blocked, leakage of the atomizing matrix can be avoided.

[0092] See Figures 1-5 As shown, the atomizing device further includes at least one connecting component 15 and at least one electrical connector 16. Both the connecting component 15 and the connector 16 are disposed on the side of the outer wall of the liquid storage chamber 10 where the liquid replenishment hole 13 is provided. The connecting component 15 can be detachably connected to a power replenishment device that replenishes electrical energy to the power supply unit 100, and the electrical connector 16 can be electrically connected to the power replenishment device that replenishes electrical energy to the power supply unit 100, so that electrical energy can be replenished to the power supply unit 100 through the power replenishment device.

[0093] The connecting component 15 can be a magnet, which can be magnetically connected to the magnet or iron component on the power replenishment device. The electrical connector 16 can be a connecting terminal, with one end electrically connected to the power supply unit 100 and the other end electrically connected to the power replenishment device.

[0094] In summary, the atomizing device provided by this utility model has a control valve that can open the inlet and outlet ports when it is necessary to supply atomizing matrix to the storage chamber, thereby preventing the atomizing chamber from storing excessive atomizing matrix for a long time. This also avoids the problem of leakage of atomizing matrix through the atomizing core due to changes in internal and external pressure difference, thus optimizing the user experience and reducing user costs.
