[0040] 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.
[0041] 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.
[0042] 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. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).
[0043] The atomizing device can be used to atomize water to humidify the air, or to atomize liquid or paste-based aromatherapy products to purify or improve air quality. It can also be used to heat plant leaves, tobacco paste, e-liquid, etc., to produce aerosols for users to consume. This application does not limit the objects atomized by the atomizing core; the specific selection can be based on actual needs. In the following embodiments, the atomizing core is used to illustrate the atomization of plant leaves, tobacco paste, e-liquid, etc., to produce aerosols. For simplicity, plant leaves, tobacco paste, e-liquid, etc., are collectively referred to as the atomizing matrix.
[0044] In related technologies, the liquid storage chamber of the atomizing device has a liquid storage cavity, in which the atomizing core is installed. To prevent leakage of the atomized matrix to the outside of the product due to a pressure difference between the internal and external pressures of the liquid storage cavity caused by environmental factors, a liquid storage tank is also provided inside the liquid storage chamber, located below and connected to the liquid storage cavity. This liquid storage tank stores the atomized matrix that leaks through the atomizing core. However, the atomized matrix flowing into the liquid storage tank reduces the overall amount of atomized matrix in the product, further reducing the atomization amount of the aerosol and resulting in waste of the atomized matrix.
[0045] To address the aforementioned issues, this application provides an atomizing device and an atomizing equipment. The leaked atomizing matrix is stored in a second liquid storage chamber and a liquid storage component within the second liquid storage chamber to prevent leakage of the atomizing matrix. The stored atomizing matrix can also be reversed and returned to the first liquid storage chamber through the liquid storage component, avoiding waste of the atomizing matrix and ensuring the atomization amount of the aerosol.
[0046] See Figures 1-5 As shown, the atomizing device 100 provided in this embodiment includes a liquid storage chamber 10, an atomizing component 20, and a liquid storage component 30.
[0047] The liquid storage chamber 10 has a first liquid storage cavity 111 and a second liquid storage cavity 112 that are interconnected. For example, the first liquid storage cavity 111 and the second liquid storage cavity 112 can be connected by a channel or pipe. The first liquid storage cavity 111 is used to store the atomizing matrix. The atomizing matrix stored in the first liquid storage cavity 111 can be directly atomized by the atomizing component 20 to generate an aerosol. The atomizing matrix is e-liquid in liquid form. When a pressure difference is generated between the inside of the first liquid storage cavity 111 and the outside (the outside of the liquid storage chamber 10 or the outside of the atomizing device 100), and the pressure difference is high enough that at least a portion of the atomizing matrix stored in the first liquid storage cavity 111 can flow to the second liquid storage cavity 112, the second liquid storage cavity 112 stores at least a portion of the atomizing matrix flowing out of the first liquid storage cavity 111 to prevent the atomizing matrix from leaking to the outside of the liquid storage chamber 10 or the atomizing device 100. In other words, the first liquid storage chamber 111 has a "storage" function, while the second liquid storage chamber 112 has a "buffer" function.
[0048] During use, the atomizing matrix of the atomizing device 100 is supplied to the atomizing component 20, which heats and atomizes the matrix to produce an aerosol. The atomizing component 20 is fluidly connected to the first liquid storage chamber 111. The atomizing matrix is supplied to the atomizing component 20 via flow or capillary action. As the atomizing matrix is consumed, the amount of atomizing matrix inside the first liquid storage chamber 111 decreases. After a certain reduction, the volume above the stored atomizing matrix in the first liquid storage chamber 111 relatively increases, causing a decrease in pressure inside the first liquid storage chamber 111 relative to the external pressure of the atomizing device 100. Due to the pressure difference, the atomizing matrix in the first liquid storage chamber 111 is difficult to flow to or be guided to the atomizing component 20, leading to the problem of the atomizing component 20 burning out. At this time, air can be supplied to the first liquid storage chamber 111 through the ventilation structure 113 to maintain a relatively balanced pressure difference between the inside of the first liquid storage chamber 111 and the outside of the atomizing device 100.
[0049] The atomizing component 20 is disposed inside the first liquid storage chamber 111 and is fluidly connected to the first liquid storage chamber 111. As previously described, the atomizing matrix in the first liquid storage chamber 111 is supplied to the atomizing component 20 by means of flow or capillary action. Similarly, when the atomizing device 100 is not in use (i.e., the atomizing component 20 is not heating the atomizing matrix), if the pressure inside the first liquid storage chamber 111 decreases relative to the external pressure due to external environmental factors (e.g., increased temperature or increased altitude), at least a portion of the atomizing matrix can flow into the second liquid storage chamber 112 through the atomizing component 20, or at least a portion of the atomizing matrix can flow into the second liquid storage chamber 112 for storage through the fluidly connected portion between the first liquid storage chamber 111 and the second liquid storage chamber 112.
[0050] A liquid storage assembly 30 is disposed at least within the second liquid storage chamber 112. The liquid storage assembly 30 is configured to allow at least a portion of the atomized matrix to flow bidirectionally between the first liquid storage chamber 111 and the second liquid storage chamber 112. Specifically, when the internal pressure of the first liquid storage chamber 111 decreases relative to the external pressure, the liquid storage assembly 30 allows at least a portion of the atomized matrix located in the first liquid storage chamber 111 to flow into the second liquid storage chamber 112 and be stored by the liquid storage assembly 30. Conversely, when the internal pressure of the first liquid storage chamber 111 increases relative to the external pressure, the liquid storage assembly 30 allows at least a portion of the atomized matrix stored in the second liquid storage chamber 112 to flow back into the first liquid storage chamber 111. The liquid storage component 30 may be made of fiber cotton and store at least a portion of the atomized matrix flowing from the first liquid storage chamber 111 to the second liquid storage chamber 112 by capillary action or by adsorption. Alternatively, at least a portion of the atomized matrix adsorbed and stored thereon may flow back from the second liquid storage chamber 112 to the first liquid storage chamber 111 by capillary action.
[0051] In this embodiment, the liquid storage chamber 10 is also provided with a ventilation structure 113. The ventilation structure 113 is fluidly connected to the first liquid storage chamber 111. The pressure difference between the inside of the first liquid storage chamber 111 and the outside of the liquid storage chamber 10 will occur due to the consumption of the atomizing matrix in the first liquid storage chamber 111 and changes in external environmental factors. The ventilation structure 113 is configured to allow external air to enter the first liquid storage chamber 111 to adjust the pressure difference between the inside of the first liquid storage chamber 111 and the outside of the liquid storage chamber 10 (or the atomizing device 100), so that the pressure difference between the inside and outside of the first liquid storage chamber 111 reaches a relatively balanced state. In this state, the atomizing matrix in the first liquid storage chamber 111 is not easy to flow to the second liquid storage chamber 112 through the liquid storage component 30. At the same time, the atomizing matrix stored in the second liquid storage chamber 112 is also not easy to flow to the first liquid storage chamber 111 through the liquid storage component 30.
[0052] When a specific pressure difference is generated inside and outside the first liquid storage chamber 111, where the specific pressure difference is not a fixed value, but refers to a pressure difference that reaches a certain level, its value can be -300pa, -350pa, -400pa, etc., at least part of the atomizing matrix stored in the first liquid storage chamber 111 flows into the second liquid storage chamber 112 and is stored by the liquid storage component 30, thereby avoiding the problem of atomizing matrix leakage. Alternatively, at least part of the atomizing matrix that flows into the second liquid storage chamber 112 and is stored by the liquid storage component 30 flows back from the liquid storage component 30 to the first liquid storage chamber 111, so that at least part of the atomizing matrix stored in the liquid storage component 30 flows back to the first liquid storage chamber 111, avoiding the problem of atomizing matrix waste.
[0053] It should be noted that the pressure difference between the first liquid storage chamber 111 and the outside when the atomizing matrix flows from the first liquid storage chamber 111 to the second liquid storage chamber 112 is different from the pressure difference between the first liquid storage chamber 111 and the outside when the atomizing matrix flows back from the second liquid storage chamber 112 to the first liquid storage chamber 111. Please refer to the following embodiments for details.
[0054] See Figure 4 and Figure 5 As shown, the interior of the liquid storage chamber 10 is also provided with a connecting channel 114 that connects the first liquid storage chamber 111 and the second liquid storage chamber 112. The connecting channel 114 forms a connection between the first liquid storage chamber 111 and the second liquid storage chamber 112. The atomized matrix can flow from the first liquid storage chamber 111 into the second liquid storage chamber 112 through the connecting channel 114, or flow back from the second liquid storage chamber 112 to the first liquid storage chamber 111. The liquid storage component 30 is disposed in the connecting channel 114 and the second liquid storage chamber 112.
[0055] In this embodiment, when the pressure difference between the first liquid storage chamber 111 and the outside is equal to a preset pressure difference, the first liquid storage chamber 111 and the second liquid storage chamber 112 are in a state of gas-liquid equilibrium, allowing the atomizing matrix in the first liquid storage chamber 111 to be continuously and stably supplied to the atomizing assembly 20. When the pressure difference between the first liquid storage chamber 111 and the outside is greater than the preset pressure difference, at least a portion of the atomizing matrix is allowed to flow into the second liquid storage chamber 112 through the connecting channel 114 and be stored by the liquid storage assembly 30. When the pressure difference between the first liquid storage chamber 111 and the outside is less than the preset pressure difference, the liquid storage assembly 30 is configured to allow at least a portion of the atomizing matrix to flow back from the second liquid storage chamber 112 to the first liquid storage chamber 111 through the connecting channel 114.
[0056] In a specific embodiment, the pressure inside the first liquid storage chamber 111 is set as P1, and the pressure outside the liquid storage tank 10 is set as P2. The pressure difference is ΔP = P1 - P2. Normally, the pressure difference ΔP between the pressure P1 inside the first liquid storage chamber 111 and the pressure P2 outside the liquid storage tank 10 is maintained at a preset pressure difference. This preset pressure difference includes a first preset pressure difference, which is -400 Pa to -600 Pa. In a preferred embodiment, the preset pressure difference is -500 Pa. The following embodiment uses a preset pressure difference of -500 Pa as an example. Setting the pressure difference ΔP to -500 Pa as the preset pressure difference, under this preset pressure difference, the first liquid storage chamber 111 and the second liquid storage chamber 112 maintain a state of gas-liquid equilibrium. That is, the atomizing matrix in the first liquid storage chamber 111 can continuously and stably flow to the atomizing component 20.
[0057] As the ambient temperature rises or the area is at a high altitude, the internal pressure P1 of the first liquid storage chamber 111 increases relative to the external pressure P2 of the liquid storage tank 10. When this pressure difference ΔP exceeds the preset pressure difference of -500 Pa, at least a portion of the atomized matrix flows from the first liquid storage chamber 111 into the second liquid storage chamber 112 and is stored by the liquid storage component 30, preventing the atomized matrix from leaking to the outside of the atomizing device 100. Specifically, at least a portion of the atomized matrix can flow into the second liquid storage chamber 112 through the connection between the atomizing component 20 and the second liquid storage chamber 112, and / or at least a portion of the atomized matrix can flow into the second liquid storage chamber 112 through the connection channel 114 between the first liquid storage chamber 111 and the second liquid storage chamber 112, and be stored by the liquid storage component 30 by adsorption.
[0058] As the ambient temperature decreases or the atomizing matrix inside the first liquid storage chamber 111 is consumed, the pressure P1 inside the first liquid storage chamber 111 decreases relative to the external pressure P2 of the liquid storage tank 10. When the pressure difference ΔP is less than the preset pressure difference of -500 Pa, the ventilation structure 113 allows external gas to enter the first liquid storage chamber 111, maintaining the pressure difference ΔP at -500 Pa to maintain a gas-liquid balance. This ensures that the atomizing matrix in the first liquid storage chamber 111 continuously replenishes the atomizing component 20. Simultaneously, the liquid storage component 30 can reverse the flow of at least a portion of the atomizing matrix it stores back to the first liquid storage chamber 111, avoiding waste of the atomizing matrix and ensuring the atomization volume of the aerosol. Since the liquid storage component 30 is made of fiber cotton, it can be provided with fiber cotton with different capillary forces in different parts. When the pressure difference ΔP is less than the preset pressure difference -500Pa, the atomized matrix can be reversed by different capillary forces, so that at least part of the atomized matrix can flow back to the first liquid storage chamber 111. Please refer to the following embodiments for details.
[0059] In a specific embodiment, when the pressure difference ΔP is less than a preset pressure difference of -500Pa and greater than -1000Pa, the ventilation structure 113 can allow external gas to enter the first liquid storage chamber 111. At the same time, the liquid storage component 30 can cause at least part of the atomized matrix stored therein to flow back into the first liquid storage chamber 111.
[0060] In the above embodiments, when the pressure difference ΔP is greater than the preset pressure difference -500Pa, at least a portion of the atomizing matrix can flow from the first liquid storage chamber 111 into the second liquid storage chamber 112 and be stored by the liquid storage component 30, thus preventing leakage of the atomizing matrix. When the pressure difference ΔP is less than the preset pressure difference -500Pa, external gas can be supplied to the first liquid storage chamber 111 through the ventilation structure 113 to maintain a gas-liquid balance, thereby ensuring a continuous supply of atomizing matrix to the atomizing component 20. At the same time, the liquid storage component 30 can cause at least a portion of the atomizing matrix stored therein to flow back into the first liquid storage chamber 111, avoiding waste of the atomizing matrix and ensuring the atomization amount of the aerosol.
[0061] In this embodiment, when the pressure difference ΔP is greater than a preset pressure difference of -500 Pa, the ventilation structure 113 allows at least a portion of the atomized matrix to flow from the first liquid storage chamber 111 into the second liquid storage chamber 112 and be stored by the liquid storage component 30 through the connecting channel 114. The ventilation structure 113 is disposed in the connecting channel 114. The liquid storage chamber 10 is also provided with an air inlet 115 communicating with the second liquid storage chamber 112. The ventilation structure 113 maintains communication between the first liquid storage chamber 111 and the outside through the air inlet 115. When the pressure difference ΔP between the pressure inside the first liquid storage chamber 111 and the pressure outside the liquid storage chamber 10 is less than the preset pressure difference of -500 Pa, external air can enter the first liquid storage chamber 111 through the air inlet 115 and the ventilation structure 113.
[0062] like Figure 4 and Figure 5As shown, the liquid storage assembly 30 includes a first liquid guiding element 31 and a first liquid storage element 32. The first liquid guiding element 31 is disposed in the communicating channel 114, and the outer surface of the first liquid guiding element 31 is in contact with the channel wall of the communicating channel 114. The first liquid storage element 32 is disposed in the second liquid storage chamber 112, and at least a portion of the first liquid storage element 32 is in contact with the first liquid guiding element 31. Both the first liquid guiding element 31 and the first liquid storage element 32 are made of fiber cotton. At least a portion of the atomized matrix flowing through the communicating channel 114 to the second liquid storage chamber 112 is first adsorbed by capillary action through the first liquid guiding element 31, and then guided to the first liquid storage element 32 by capillary action. The first liquid storage element 32 is configured to store at least a portion of the atomized matrix entering the second liquid storage chamber 112. The first liquid guide 31 is configured to control at least a portion of the atomized matrix to flow from the first liquid storage chamber 111 to the second liquid storage chamber 112 according to the change of pressure difference ΔP (pressure difference ΔP is greater than a preset pressure difference), or to control at least a portion of the atomized matrix stored in the first liquid storage chamber 32 to flow back from the second liquid storage chamber 112 to the first liquid storage chamber 111 according to the change of pressure difference ΔP (pressure difference ΔP is less than a preset pressure difference).
[0063] In this embodiment, both the first liquid guiding element 31 and the first liquid storage element 32 adopt a porous structure with adsorption function, specifically made of fiber cotton material, which has multiple pores distributed inside. These pores can adsorb the atomized matrix through capillary force. The force that adsorbs the atomized matrix through the pores is capillary force. The greater the capillary force, the stronger the adsorption force. Therefore, in this application, the capillary force of the first liquid guiding element 31 is greater than the capillary force of the first liquid storage element 32. When the pressure difference ΔP inside the first liquid storage chamber 111 relative to the outside of the liquid storage tank 10 is less than a preset pressure difference, the first liquid guiding element 31 can reverse-absorb at least a portion of the atomized matrix stored in the first liquid storage element 32 to flow back from the second liquid storage chamber 112 to the first liquid storage chamber 111.
[0064] The magnitude of capillary force is related to the size of the pore distribution and the pore diameter. Under the same fiber cotton material, the first liquid guiding component 31 and the first liquid storage component 32 with different volumes will have different capillary forces. Under different fiber cotton materials, the more pores distributed and the smaller the pore diameter, the greater the capillary force. Therefore, the specific materials of the first liquid guiding component 31 and the first liquid storage component 32 can be selected according to actual needs.
[0065] Combination Figures 4-5 and Figure 7As shown, the ventilation structure 113 includes a ventilation groove 1131, which is disposed in the connecting channel 114 and extends along the length of the connecting channel 114. In a specific embodiment, the ventilation groove 1131 is recessed into the channel wall along the length of the connecting channel 114, and the ventilation groove 1131 connects the first liquid storage chamber 111 and the second liquid storage chamber 112, so that the second liquid storage chamber 112 is in a state of air passage communication with the outside of the atomizing component 20.
[0066] In this embodiment, the outer surface of the first liquid guide 31 is attached to the channel wall of the connecting channel 114, so that the air exchange groove 1131 can connect the first liquid storage chamber 111 and the second liquid storage chamber 112. Furthermore, the air exchange groove 1131 can keep the first liquid storage chamber 111 connected to the outside through the air inlet 115, so that the second liquid storage chamber 112 can form an air passage connection with the outside of the atomizing component 20.
[0067] See Figures 1-5 As shown, the liquid storage chamber 10 is also equipped with a suction nozzle 119, and the interior of the liquid storage chamber 10 is also equipped with a suction channel 1191 that penetrates the suction nozzle 119. The atomizing component 20 is also in fluid communication with the suction channel 1191. In actual use, the user draws through the suction nozzle 119, creating a pressure difference in the second liquid storage chamber 112 relative to the outside of the atomizing device 100. Under the action of this pressure difference, external air can enter the interior of the atomizing component 20 through the air inlet 115 from the second liquid storage chamber 112 to generate airflow. Under the action of this airflow, the aerosol generated by the atomization of the atomizing component 20 is carried out and output through the suction channel 1191.
[0068] During the aerosol's transport within the atomizing component 20 and the nozzle channel 1191, condensation can easily occur due to temperature changes, producing condensate. This condensate can flow back into the second storage chamber 112 under its own gravity, leading to liquid leakage. For further details, please refer to... Figure 4 , Figure 5 and Figure 9 As shown, the atomizing device 100 provided in this application also includes a liquid suction member 40. The bottom of the second liquid storage chamber 112 is also provided with an isolation member 116, which divides the bottom of the second liquid storage chamber 112 into a first region 117 and a second region 118. The liquid suction member 40 is disposed in the first region 117 and is made of fiber cotton. The liquid suction member 40 absorbs the returned condensate. An air inlet 115 is disposed at the bottom of the second liquid storage chamber 112 and communicates with the first region 117. The first liquid storage member 32 is disposed in the first region 118, and the projection of the atomizing component 20 onto the first region 117 is located within the first region 117. Therefore, when the condensate returning from the atomizing component 20 drips into the first region 117, it is absorbed by the liquid suction member 40 disposed in the first region 117, preventing leakage of the condensate.
[0069] Meanwhile, since the first region 117 and the second region 118 are separated by the separator 116, which is a raised structure at the bottom of the second liquid storage chamber 112, the first region 117 and the second region 118 are two relatively independent regions. Even if the condensate is not adsorbed by the liquid suction member 40 or the liquid suction member 40 reaches saturation and overflows, the condensate will be isolated by the separator 116 to prevent the condensate from being adsorbed by the first liquid storage member 32 and flowing back into the first liquid storage chamber 111, causing it to mix with the atomizing matrix.
[0070] like Figure 3 As shown, the atomizing component 20 has an atomizing channel 2221. The projection of the atomizing channel 2221 on the first region 117 is located within the first region 117. Under its own gravity, the condensate flows back along the channel wall of the atomizing channel 2221 and flows back to the first region 117 where it is adsorbed by the liquid suction component 40.
[0071] See Figures 1-5 and Figures 7-9 As shown, the liquid storage tank 10 includes a tank body 11, a support 12, and a base 13. One end of the tank body 11 has an opening 110. The support 12 is installed inside the tank body 11, and the support 12 and the inner cavity of the tank body 11 form a first liquid storage chamber 111. The base 13 is installed at the opening 110, and the base 13 and the support 12 are spaced apart to form a second liquid storage chamber 112.
[0072] To ensure the airtightness of the support 12 and base 13 with the inner cavity of the chamber 11, the liquid storage chamber 10 also includes a sealing element 14, which is installed between the connection between the atomizing chamber 12 and the base 13 and the inner cavity wall of the chamber 11.
[0073] In this embodiment, an annular protrusion 115 is provided on the side of the base 13 facing the bracket 12. The inner cavity of the annular protrusion 115 forms an air inlet 115. The atomizing component 20 has an atomizing channel 2221. The two ends of the air inlet 115 are respectively connected to the atomizing channel 2221 and the second liquid storage chamber 112.
[0074] Since the liquid suction member 40 absorbs the returned condensate by adsorption, when the liquid suction member 40 reaches saturation, there is also a problem of condensate leakage from the air inlet 115. The annular protrusion 1151 provided on the base 13 in this application can block the condensate to further prevent the problem of condensate leakage.
[0075] See Figures 3-5 and Figure 8As shown, the bracket 12 is also provided with a socket 121, which connects the first liquid storage chamber 111 and the second liquid storage chamber 112. The atomizing assembly 20 includes an atomizing tube 21, an atomizing core 22, and a second liquid storage component 23. The atomizing core 22 is installed inside the atomizing tube 21, and the atomizing channel 2221 is provided through the atomizing core 22. The atomizing tube 21 has an inlet hole 211 that communicates with the atomizing core 22. The atomizing tube 21 is inserted into the socket 121, and the inlet hole 211 is in fluid communication with the first liquid storage chamber 111. The second liquid storage component 23 is sleeved on the outside of the atomizing tube 21 and covers the inlet hole 211. The second liquid storage component 23 is in fluid communication with the first liquid storage chamber 111, so that the atomizing matrix can be replenished to the atomizing core 22 through the inlet hole 211. The atomizing core 22 atomizes the atomizing matrix into an aerosol by heating.
[0076] In this embodiment, the socket 121 and the connecting channel 114 are both disposed on the bracket 12, and the separator 116 is disposed on the side of the base 13 facing the bracket 12.
[0077] In one embodiment of this application, such as Figure 3 and Figure 6 As shown, the atomizing core 22 includes a positioning tube 221, a second liquid guiding component 222, and a heating component 223. The positioning tube 221 is inserted inside the atomizing tube 21. The second liquid guiding component 222 is disposed in the inner cavity of the positioning tube 221. The atomizing channel 2221 is disposed through the second liquid guiding component 222. The heating component 223 is disposed in close contact with the channel wall of the atomizing channel 2221 of the second liquid guiding component 222. The tube wall of the positioning tube 221 is provided with at least one liquid passage hole 2211. The liquid passage hole 2211 at least partially overlaps with the liquid inlet hole 211 on the atomizing tube 21. The second liquid storage component 23 surrounds the outer wall of the atomizing tube 21 and covers the liquid inlet hole 211. The second liquid storage component 23 can store the atomizing matrix in the first liquid storage chamber 111 and transfer the atomizing matrix to the second liquid guiding component 222 by capillary action through the liquid passage hole 2211 and the liquid inlet hole 211.
[0078] like Figure 1 As shown, the chamber 11 is also provided with a liquid replenishment hole 15, which is connected to the first liquid storage chamber 111. A sealing member 16 is detachably connected to the liquid replenishment hole 15. The liquid replenishment hole 15 can be opened or closed by the sealing member 16. When the liquid replenishment hole 15 is open, the atomized matrix can be replenished into the first liquid storage chamber 111.
[0079] This application also provides an atomizing device, including the atomizing device 100 in the above embodiments, and a power supply unit. The power supply unit is detachably connected to the liquid storage tank 10. The power supply unit is configured to provide electrical energy to the heating element 223 in the atomizing assembly 20 to drive the heating element 223 to generate heat that atomizes the atomizing matrix into an aerosol.
[0080] In summary, in the atomizing device and atomizing equipment provided in this application, the ventilation structure allows external air to enter the first liquid storage chamber when the pressure difference between the inside and outside of the first liquid storage chamber is less than a preset pressure difference. This regulates the pressure difference between the inside of the first liquid storage chamber and the outside of the storage chamber, maintaining the first liquid storage chamber in a state of gas-liquid equilibrium and ensuring a continuous supply of atomizing matrix to the atomizing component. Simultaneously, based on changes in the pressure difference between the inside and outside of the first liquid storage chamber, at least a portion of the atomizing matrix stored in the first liquid storage chamber flows from the first liquid storage chamber into the second liquid storage chamber and is stored by the storage component, preventing leakage of the atomizing matrix. Alternatively, at least a portion of the atomizing matrix flows back from the second liquid storage chamber to the first liquid storage chamber, preventing waste of the atomizing matrix and ensuring the atomization volume of the aerosol.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
