[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] According to a first aspect of this application, a liquid reservoir 10 is provided.

[0053] Reference Figures 1 to 3 , Figure 1 Schematic diagrams of the liquid reservoir provided for some embodiments of this application; Figure 2 Cross-sectional views of a reservoir provided for some embodiments of this application; Figure 3 This is a cross-sectional view of a reservoir provided for some embodiments of this application. The reservoir 10 includes a first housing 11 and a control valve 12. The first housing 11 is provided with a liquid outlet 1111, and the reservoir 10 is configured to replenish liquid to the atomizer 20 through the liquid outlet 1111. The control valve 12 is connected to the first housing 11 and is configured to control the opening and closing of the liquid outlet 1111.

[0054] It is understood that the reservoir 10 is used to contain the aerosol matrix. The aerosol matrix is ​​a fluid and has flow properties. The matrix material of the aerosol matrix can be propylene glycol, vegetable glycerin, food-grade flavoring, etc.

[0055] When the control valve 12 controls the outlet 1111 to open, the inside and outside of the reservoir 10 are connected, and the aerosol matrix in the reservoir 10 can flow out from the outlet 1111; when the control valve 12 controls the outlet 1111 to close, the inside and outside of the reservoir 10 are isolated, and the aerosol matrix cannot flow out from the outlet 1111.

[0056] The control valve 12 can be located inside the reservoir 10 or outside the reservoir 10.

[0057] Among them, the control valve 12 can be a mechanical valve or a solenoid valve.

[0058] In this embodiment, a control valve 12 controls the opening and closing of the liquid outlet 1111. When liquid needs to be added to the atomizer 20, the control valve 12 controls the liquid outlet 1111 to open; when the reservoir 10 is separated from the atomizer 20, the control valve 12 controls the liquid outlet 1111 to close. This design helps reduce the risk of leakage from the reservoir 10 and facilitates the use of the reservoir 10 as an external reservoir.

[0059] The advantages of having an external reservoir 10 are: it can be transported and distributed independently of the atomizer 20, and users can easily replace reservoirs 10 with different capacities or flavors without replacing the entire atomizer 100, thus improving the flexibility of use; in addition, this design also helps to flexibly expand the capacity of the atomizer 100, increasing the liquid storage capacity without replacing the main structure of the atomizer 100.

[0060] In practical applications, a small-capacity atomizer 20 that meets the basic capacity requirements can be prepared first to achieve portability; when the capacity needs to be increased, the liquid can be replenished by connecting the liquid reservoir 10.

[0061] In some embodiments, the interior of the first housing 11 has a first liquid storage space 13 for accommodating the first aerosol matrix, and the control valve 12 is disposed within the first liquid storage space 13.

[0062] In this embodiment of the application, by placing the control valve 12 inside the reservoir 10, the space occupied by the external space can be reduced.

[0063] Reference Figure 2 In some embodiments, the control valve 12 includes a plug 121 and a mounting bracket 122. The mounting bracket 122 is connected to the first housing 11, and the plug 121 is slidably disposed on the mounting bracket 122 to control the opening and closing of the liquid outlet 1111.

[0064] It is understandable that the sealing component 121 can control the opening and closing of the liquid outlet 1111 by sliding under the action of external force.

[0065] In practical applications, when the reservoir 10 is connected to the atomizer 20, the atomizer 20 pushes the sealing member 121 to slide to open the liquid outlet 1111; when the reservoir 10 is separated from the atomizer 20, the external force acting on the reservoir 10 is removed, and the sealing member 121 slides to close the liquid outlet 1111.

[0066] In some embodiments, the mounting bracket 122 is provided with a guide post 1221, and the sealing member 121 is sleeved on the guide post 1221. The guide post 1221 can guide the sealing member 121, thereby reducing the risk of tilting during the sliding process of the sealing member 121.

[0067] Reference Figure 4 and Figure 2 , Figure 4 The diagram below shows the structure of a sealing member provided in some embodiments of this application. In some embodiments, the sealing member 121 is provided with a mounting hole 1211 and a drain port 1212. A guide post 1221 passes through the mounting hole 1211. The sealing member 121 has an assembly side away from the drain port 1111. The drain port 1212 is located away from the assembly side and communicates with the mounting hole 1211.

[0068] During the sliding process of the sealing component 121, the first aerosol matrix can easily enter the mounting hole 1211 and generate resistance to the sliding of the sealing component 121. However, in this embodiment, the liquid accumulated in the mounting hole 1211 is discharged through the drain port 1212, which can reduce the sliding resistance of the sealing component 121 and thereby improve the movement flexibility of the sealing component 121.

[0069] In some embodiments, the control valve 12 further includes a reset member 123, one end of which is connected to the plugging member 121 and the other end is connected to the mounting bracket 122. The reset member 123 is configured to accumulate potential energy during the process of the plugging member 121 being opened by an external force to open the liquid outlet 1111, and to drive the plugging member 121 to reset after the external force on the plugging member 121 is removed, so as to close the liquid outlet 1111.

[0070] The reset element 123 can be a spring, a spring sheet, an elastic sleeve, etc. For example, the reset element 123 is a spring, which is sleeved on the guide post 1221.

[0071] In this embodiment of the application, by setting a reset member 123, the sealing member 121 can be automatically reset, and the liquid outlet 1111 can be closed in time.

[0072] In practical applications, when the reservoir 10 is connected to the atomizer 20, the atomizer 20 pushes the sealing member 121 to slide away from the liquid outlet 1111 to open the liquid outlet 1111; when the reservoir 10 is separated from the atomizer 20, the sealing member 121 slides towards the liquid outlet 1111 under the action of the reset member 123 to close the liquid outlet 1111.

[0073] Reference Figure 2In some embodiments, the first outer casing 11 includes a first casing 111 and a base 112, the base 112 being connected to the first casing 111, a mounting bracket 122 being disposed on the base 112, and a liquid outlet 1111 being disposed on the first casing 111. With this configuration, the base 112 can stably support the mounting bracket 122, thereby improving the structural stability of the liquid reservoir 10.

[0074] For example, the base 112 is disposed on the bottom wall of the first housing 111 and is located within the first liquid storage space 13.

[0075] Reference Figure 1 In some embodiments, the liquid outlet 1111 is located on the side wall of the first housing 111, so that the liquid reservoir 10 can be connected to the atomizer 20 from the side and replenished with liquid. This design helps to arrange the liquid reservoir 10 and the atomizer 20 side by side in the lateral direction, thereby reducing the height dimension of the atomizing device 100.

[0076] To improve liquid guiding efficiency and atomization uniformity, multiple liquid outlets 1111 can be provided. In some embodiments, the multiple liquid outlets 1111 are spaced apart along the height direction of the liquid reservoir 10.

[0077] For example, there are two outlets 1111, and correspondingly, there are two sealing elements 121, each sealing element 121 corresponding to one outlet 1111.

[0078] For example, the mounting bracket 122 is provided with two guide posts 1221, which are spaced apart along the height direction of the liquid reservoir 10, and a sealing member 121 is fitted on each guide post 1221.

[0079] Reference Figure 2 In some embodiments, the reservoir 10 further includes a seal 14 disposed inside the first housing 11. The seal 14 is used to seal the gap between the outlet 1111 and the plug 121 to reduce the risk of leakage.

[0080] It is understandable that the sealing element 121 presses against the sealing element 14 to close the liquid outlet 1111.

[0081] The material of the seal 14 can be rubber, silicone, etc.

[0082] Reference Figure 1 In some embodiments, the reservoir 10 is provided with a first connecting portion 15, which is used for detachable connection with the atomizer 20. With this configuration, the first connecting portion 15 can improve the connection stability between the reservoir 10 and the atomizer 20, reduce the risk of leakage, and the detachable connection structure facilitates the assembly and disassembly of the reservoir 10 and the atomizer 20.

[0083] To further facilitate the assembly and disassembly of the reservoir 10 and the atomizer 20, in some embodiments, the first connecting part 15 is a magnetic component, and the reservoir 10 is configured to be magnetically connected to the atomizer 20 through the first connecting part 15.

[0084] Magnetic components refer to components that possess magnetism or can exhibit magnetism under the influence of a magnetic field. In this embodiment, the first connecting part 15 can interact with the atomizer 20 through a magnetic field, thereby enabling a detachable connection between the liquid reservoir 10 and the atomizer 20.

[0085] For example, the first connecting part 15 is elongated and extends along the height direction of the liquid reservoir 10 to increase the contact area between the first connecting part 15 and the atomizer 20, thereby improving the connection stability between the liquid reservoir 10 and the atomizer 20.

[0086] In one example, the first connecting part 15 is a magnet.

[0087] In some embodiments, there are two first connecting portions 15, which are spaced apart, and the liquid outlet 1111 is located between the two first connecting portions 15.

[0088] For example, the two first connecting portions 15 are arranged laterally at intervals.

[0089] According to a second aspect of this application, an atomizing device 100 is provided, including an atomizer 20 and the aforementioned liquid reservoir 10, wherein the liquid reservoir 10 is used to replenish liquid to the atomizer 20.

[0090] Reference Figures 5 to 7 , Figure 5 Schematic diagrams of the atomizer provided for some embodiments of this application; Figure 6 Cross-sectional views of an atomizer provided for some embodiments of this application; Figure 7 This is a perspective cross-sectional view of an atomizer provided for some embodiments of this application. The atomizer 20 includes a second housing 21, on which a flow guide column 24 is provided, and inside which there is a second liquid storage space 23 for accommodating a second aerosol matrix. The flow guide column 24 has a flow channel 241, and the second liquid storage space 23 is connected to the liquid outlet 1111 through the flow channel 241.

[0091] Specifically: when the reservoir 10 is assembled with the atomizer 20, the guide column 24 is inserted into the outlet 1111, and the end of the guide column 24 abuts against the sealing member 121 and pushes the sealing member 121 to slide, thereby opening the outlet 1111; when the reservoir 10 is disassembled from the atomizer 20, the guide column 24 is withdrawn from the outlet 1111, and the sealing member 121 slides in the opposite direction under the action of the reset member 123 and abuts against the sealing member 14, thereby closing the outlet 1111.

[0092] Specifically, when an increase in capacity is required, the second aerosol matrix is ​​the same as the first aerosol matrix; when a change in aerosol type is required, the second aerosol matrix is ​​different from the first aerosol matrix.

[0093] In this embodiment, the drainage column 24 can guide the first aerosol matrix into the atomizer 20, thereby reducing the risk of leakage.

[0094] Reference Figure 8 and Figure 9 , Figure 8 Side view of an atomizer provided for some embodiments of this application; Figure 9 for Figure 8 Enlarged view of part A. In some embodiments, the atomizer 20 further includes a flow-blocking element 25, which is disposed in the flow channel 241 and is used to divide the flow channel 241 into a plurality of sub-channels 2411. The plurality of sub-channels 2411 are arranged circumferentially around the flow-blocking element 25, and the second liquid storage space 23 is connected to the liquid outlet 1111 through the sub-channels 2411.

[0095] It is understandable that the flow obstruction element 25 occupies a part of the flow channel 241 and divides the flow channel 241 into multiple sub-channels 2411.

[0096] In some embodiments, the sub-channel 2411 is a groove provided on the inner wall of the drainage channel 241. Exemplarily, the inner wall of the drainage channel 241 is provided with a plurality of grooves, which are spaced apart circumferentially around the flow-blocking member 25, and each groove extends axially along the drainage column 24.

[0097] The shape of the flow-blocking element 25 is adapted to the shape of the flow-draining column 24. For example, both the flow-blocking element 25 and the flow-draining column 24 are cylindrical.

[0098] Air bubbles can easily accumulate in the drainage channel 241, causing temporary insufficient liquid replenishment and affecting the stability of liquid replenishment. In this embodiment, the drainage channel 241 is divided into multiple sub-channels 2411 by the flow-blocking element 25, allowing the reservoir 10 to replenish liquid to the atomizer 20 through multiple sub-channels 2411. Even when one of the sub-channels 2411 is blocked by air bubbles, the other sub-channels 2411 can still replenish liquid, which helps to improve the stability of liquid replenishment.

[0099] Reference Figure 9 In some embodiments, a drainage groove 242 is provided at one end of the drainage column 24 near the liquid reservoir 10. The drainage groove 242 penetrates the outer surface of the drainage column 24 and is connected to the drainage channel 241.

[0100] When the drainage column 24 abuts against the sealing member 121, the sealing member 121 will block the drainage channel 241, resulting in a decrease in the liquid guiding efficiency. In this embodiment, the drainage groove 242 allows the first aerosol matrix to enter the drainage channel 241 from the side of the drainage column 24, thereby improving the liquid guiding efficiency.

[0101] In some embodiments, the atomizer 20 further includes an atomizing component 29 disposed within the second liquid storage space 23 for atomizing the aerosol matrix within the second liquid storage space 23.

[0102] Reference Figure 6 In some embodiments, the atomizing assembly 29 includes a support 291, a liquid guide 292, and a heating element 293. The support 291 has an atomizing channel 294 that communicates with the nozzle 28 on the atomizer 20. The liquid guide 292 and the heating element 293 are both disposed within the atomizing channel 294. The support 291 is connected to the bottom wall of the second outer shell 21. The liquid guide 292 is disposed on the support 291 and surrounds the heating element 293. The liquid guide 292 can adsorb the aerosol matrix in the second liquid storage space 23, and the heating element 293 is used to atomize the aerosol matrix adsorbed by the liquid guide 292.

[0103] The base material of the liquid guiding component 292 can be organic cotton, glass fiber, ceramic fiber, etc.

[0104] In one example, the heating element 293 is a mesh-like metal heating wire.

[0105] In some embodiments, the atomizer 20 further includes a liquid reservoir 26 located within the second liquid reservoir 23, disposed around the support 291, and in contact with the liquid guide 292.

[0106] The liquid storage component 26 occupies most of the space in the second liquid storage space 23. Its liquid storage capacity is stronger than that of the liquid guide component 292. The liquid guide component 292 is used to uniformly transport the aerosol matrix in the liquid storage component 26 to the area around the heating component 293, while the liquid storage component 26 is used to temporarily store a certain amount of aerosol matrix and continuously supply it to the liquid guide component 292 during the atomization process.

[0107] The liquid storage component 26 can be made of cotton cloth.

[0108] In practical applications, the atomizer 20 can store a small amount of aerosol matrix through the liquid storage component 26, allowing the atomizer 20 to be used independently of the liquid storage device 10. When the aerosol matrix in the atomizer 20 is insufficient, the atomizer 20 is connected to the liquid storage device 10, and the liquid storage component 26 can absorb the aerosol matrix introduced by the liquid storage device 10 and continue to supply liquid to the liquid guide component 292, so that the atomizer 20 can be used continuously.

[0109] Reference Figure 6In some embodiments, the atomizer 20 further includes a first absorbent cotton 27a and a second absorbent cotton 27b, with the liquid storage component 26 located between the first absorbent cotton 27a and the second absorbent cotton 27b. Specifically, the first absorbent cotton 27a is located at the top of the liquid storage component 26, and the second absorbent cotton 27b is located at the bottom of the liquid storage component 26. This arrangement allows the aerosol matrix within the atomizer 20 to be evenly distributed within the liquid storage component 26, improving liquid supply stability.

[0110] In some embodiments, the atomizer 20 has a second connection portion 22 for detachable connection with the reservoir 10.

[0111] The second connecting part 22 cooperates with the first connecting part 15 to improve the connection stability between the liquid reservoir 10 and the atomizer 20.

[0112] In some embodiments, the second connecting part 22 is a magnetic component, and correspondingly, the first connecting part 15 is a magnetic component, so that the reservoir 10 and the atomizer 20 are magnetically connected.

[0113] In one example, the second connecting part 22 is a magnet.

[0114] The liquid reservoir 10 provided in the above embodiments can be used as an external liquid reservoir 10 in the atomizing device 100, wherein the atomizing device 100 can be externally connected to one or more liquid reservoirs 10.

[0115] Reference Figures 10 to 12 , Figure 10 Schematic diagrams of the atomizing device provided for some embodiments of this application; Figure 11 Exploded views of atomizing devices provided for some embodiments of this application; Figure 12 The cross-sectional view of the atomizing device provided for some embodiments of this application shows that, in some embodiments, the atomizing device 100 further includes a third housing 50 and a main power supply 30. The main power supply 30 is used to supply power to the atomizer 20. Both the atomizer 20 and the main power supply 30 are disposed within the third housing 50. The third housing 50 is provided with a third connecting portion 51 for detachable connection with the liquid reservoir 10. The third connecting portion 51 facilitates the assembly and disassembly of the liquid reservoir 10.

[0116] In one example, the third connection 51 is a slot formed on the surface of the third housing 50.

[0117] When an external reservoir 10 is required: the reservoir 10 can be directly connected to the atomizer 20; in order to facilitate the structural layout of the atomizing device 100, the reservoir 10 can also be placed in a position parallel to the main power supply 30, and then connected to the atomizer 20 when in use.

[0118] When two external liquid reservoirs 10 are required, one liquid reservoir 10 can be placed side by side with the atomizer 20, and the other liquid reservoir 10 can be placed side by side with the main power supply 30 to optimize the layout of the atomizing device 100.

[0119] Figures 10 to 12 An embodiment with two external reservoirs 10 is shown. In other embodiments, to accommodate both aerosol matrix expansion and power supply expansion, the reservoirs 10 and the backup power supply 40 can be connected simultaneously.
