Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to a liquid replenishment mechanism and an atomization device. Background Technology

[0002] In atomizing devices, the liquid replenishment mechanism typically supplies liquid passively to the atomizing mechanism through only one outlet. During the liquid supply process, the air pressure in the first liquid storage chamber gradually decreases, which slows down the liquid supply rate. This results in a longer time required for the liquid matrix to wet the atomizing core, posing a risk of core clogging. Utility Model Content

[0003] This application provides a liquid replenishment mechanism and an atomizing device to solve the problem of decreased liquid supply speed caused by pressure changes in passive liquid supply.

The liquid replenishing mechanism includes a housing, in which a first liquid storage chamber for storing a liquid matrix is ​​provided. The housing has a ventilation channel and a liquid outlet communicating with the first liquid storage chamber. The atomizing mechanism includes a chamber body, in which a second liquid storage chamber is provided. The chamber body has a top support, a liquid inlet and a ventilation port communicating with the second liquid storage chamber. When the liquid replenishing mechanism and the atomizing mechanism are not connected, the ventilation channel is in a closed state. When the liquid replenishing mechanism and the atomizing mechanism are connected, the liquid inlet and the liquid outlet are aligned, so that the first liquid storage chamber and the second liquid storage chamber are connected. The top support acts on the liquid replenishing mechanism to increase the air pressure in the first liquid storage chamber, thereby causing the liquid matrix in the first liquid storage chamber to flow into the second liquid storage chamber. The ventilation port is aligned with the ventilation channel and the ventilation channel is switched to an open state, so that air exchange can be achieved between the first liquid storage chamber and the second liquid storage chamber, thereby balancing the air pressure between the first liquid storage chamber and the second liquid storage chamber.

[0015] In some embodiments, the vent hole is spaced apart from the top support portion, and the wall of the vent hole and the top support portion are configured to work together on the piston.

[0016] In some embodiments, the end of the ventilation hole is covered with a waterproof and breathable membrane; and / or, the end of the ventilation hole is covered with a cotton product.

[0017] In some embodiments, the liquid inlet and the vent are spaced apart, with the vent located near the top of the second liquid storage chamber and the liquid inlet located near the bottom of the second liquid storage chamber.

[0018] In some embodiments, the top support, the vent, and the liquid inlet are all spaced apart, and the distance between the liquid inlet and the vent is greater than the distance between the top support and the vent.

[0019] In some embodiments, the second liquid storage chamber is provided with a liquid storage element and an atomizing core assembly for heating the aerosol matrix, the liquid storage element covering the periphery of the atomizing core assembly.

[0020] In some embodiments, the liquid outlet is provided with a third sealing element, which has a cross-shaped opening or a straight opening;

[0021] When the atomizing mechanism is connected to the liquid replenishment mechanism, the wall of the liquid inlet is defined to pass through the third seal and be inserted into the liquid outlet so that the liquid inlet and the liquid outlet are in a sealed communication.

[0022] In some embodiments, during the connection process between the liquid replenishment mechanism and the atomizing mechanism, the liquid replenishment mechanism has a first position and a second position relative to the atomizing mechanism, wherein...

[0023] When the liquid replenishment mechanism is in the first position, the liquid inlet is connected to the liquid outlet so that the first liquid storage chamber and the second liquid storage chamber are connected; the vent is connected to the venting channel and the venting channel is still in the closed state.

[0024] When the liquid replenishment mechanism moves from the first position to the second position, the top holding part acts on the liquid replenishment mechanism to increase the air pressure in the first liquid storage chamber; the ventilation channel switches to the open state.

[0046] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0047] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. The terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the external structure of the atomizing device in some embodiments of this application. Figure 2 yes Figure 1A schematic diagram of the internal structure of the atomizing device in the embodiment.

[0050] This application provides an atomizing device, which includes a liquid replenishment mechanism 10 and an atomizing mechanism 20. The liquid replenishment mechanism 10 and the atomizing mechanism 20 can be separate components, but can also be connected to each other.

[0051] In some embodiments, the replenishing mechanism 10 can store more liquid matrix than the atomizing mechanism 20 for replenishing the liquid matrix to the atomizing mechanism 20 during use. The atomizing mechanism 20 can store a relatively small amount of liquid matrix and atomize the liquid matrix to generate an aerosol. Before the replenishing mechanism 10 and the atomizing mechanism 20 are combined, they exist independently of each other; and after the replenishing mechanism 10 is combined with the atomizing mechanism 20, they together define a complete atomizing device for use or aspiration of aerosol by a user.

[0052] In some embodiments, when the replenishing mechanism 10 and the atomizing mechanism 20 exist separately or independently, they cannot be used or inhaled independently by the user. The replenishing mechanism 10 and the atomizing mechanism 20 can only be used by the user when combined to define a complete atomizing device, and are recycled as a whole after the liquid matrix inside them is consumed.

[0053] Alternatively, in some embodiments, the atomizing mechanism 20 can operate independently, and the refill mechanism 10 is removably attached to the atomizing mechanism 20. The refill mechanism 10 is used as a consumable and is therefore replaceable, while the atomizing mechanism 20 is reusable. When the liquid matrix in the refill mechanism 10 is depleted, the user can remove and replace it with a new refill mechanism 10 from the atomizing mechanism 20.

[0054] The liquid replenishment mechanism 10 includes a housing 11, within which a first liquid storage chamber 111 is provided for storing the liquid matrix. Specifically, the liquid matrix can be a water-based solution, such as e-cigarette liquid containing nicotine, flavorings, etc. This type of water-based solution can be effectively converted into an aerosol by the atomizing mechanism 20 to meet the user's inhalation needs. Alternatively, it can be a liquid with medicinal ingredients, such as a solution containing medications for treating respiratory diseases, which, after atomization, can act directly on the affected area through the respiratory tract to achieve better therapeutic effects. It may also be a plant extract, such as extracts from peppermint or lemon, which, after atomization, can produce a unique aroma, providing the user with a distinctive experience.

[0055] The housing 11 is provided with a ventilation channel 12 and a liquid outlet 112 that communicate with the first liquid storage chamber 111. The ventilation channel 12 is used to realize the gas exchange inside and outside the first liquid storage chamber 111, and the liquid outlet 112 is used to export the liquid matrix in the liquid replenishment mechanism 10 to the atomizing mechanism 20.

[0056] The atomizing mechanism 20 is used to heat the liquid matrix to generate an aerosol for the user to inhale. The atomizing mechanism 20 includes a chamber 22, a second liquid storage chamber 224 is provided in the chamber 22, and the chamber 22 is provided with a top support 226, a liquid inlet 222 communicating with the second liquid storage chamber 224 and a ventilation hole 221.

[0057] When the replenishing mechanism 10 and the atomizing mechanism 20 are not connected, the ventilation channel 12 is in a closed state. This prevents the liquid matrix from leaking from the first liquid storage chamber 111 through the ventilation channel 12, allowing the replenishing mechanism 10 to store the liquid matrix independently in the first liquid storage chamber 111.

[0058] When the liquid replenishment mechanism 10 is connected to the atomizing mechanism 20, the liquid inlet 222 is aligned with the liquid outlet 112 to connect the first liquid storage chamber 111 and the second liquid storage chamber 224. The top support 226 acts on the liquid replenishment mechanism 10 to increase the air pressure in the first liquid storage chamber 111, thereby causing the liquid matrix in the first liquid storage chamber 111 to flow rapidly into the second liquid storage chamber 224. The ventilation hole 221 is aligned with the ventilation channel 12 and the ventilation channel 12 is switched to the open state to enable ventilation between the first liquid storage chamber 111 and the second liquid storage chamber 224, thereby balancing the air pressure between the first liquid storage chamber 111 and the second liquid storage chamber 224.

[0059] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," and "third" may explicitly or implicitly include at least one of those features.

[0060] The atomizing device provided in this application embodiment, through the top holding part 226 acting on the liquid replenishing mechanism 10 and increasing the air pressure in the first liquid storage chamber 111, can allow the liquid matrix to flow out of the first liquid storage chamber 111 quickly in the initial stage of suction. By designing the ventilation channel 12 to balance the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 224, when the air pressure in the first liquid storage chamber 111 decreases as the internal liquid matrix flows out, the gas in the second liquid storage chamber 224 can be quickly replenished into the first liquid storage chamber 111 through the ventilation hole 221 and the ventilation channel 12, thereby avoiding the continuous decrease in the air pressure in the first liquid storage chamber 111 in the liquid replenishing mechanism 10, increasing the liquid supply speed of the liquid replenishing mechanism 10 during suction, allowing the liquid matrix to quickly wet the atomizing core, avoiding excessive waiting time for users, and reducing the risk of core clogging.

[0061] Please see Figure 3 and Figure 4 , Figure 3 yes Figure 1 A schematic diagram of the external structure of the fluid replenishment mechanism in the embodiment. Figure 4 yes Figure 1A schematic diagram of the internal structure of the fluid replenishment mechanism in the embodiment.

[0062] In some embodiments, the fluid replenishment mechanism 10 further includes a piston 13 disposed on the housing 11, which can block the ventilation passage 12 so that the ventilation passage 12 is in a closed state.

[0063] When the liquid replenishment mechanism 10 is connected to the atomizing mechanism 20, the piston 13 can be driven to open the ventilation channel 12 so that the first liquid storage chamber 111 can communicate with the external gas through the ventilation channel 12, and at least part of the piston 13 moves into the first liquid storage chamber 111 so that the gas pressure in the first liquid storage chamber 111 increases, thereby causing the liquid matrix in the first liquid storage chamber 111 to flow out through the liquid outlet 112.

[0064] Specifically, the piston 13 can be driven by the top support 226 to switch the ventilation passage 12 to an open state. That is, the piston 13 is configured to move relative to the housing 11 from a third position to a fourth position under the drive of the top support 226. When the piston 13 is in the third position, the piston 13 blocks the ventilation passage 12; when the piston 13 is in the fourth position, the ventilation passage 12 is opened. Furthermore, the volume of the first liquid reservoir 111 partially defined when the piston 13 is in the third position is greater than the volume of the first liquid reservoir 111 partially defined when the piston 13 is in the fourth position.

[0065] In some embodiments, the ventilation channel 12 and the piston 13 can be independently disposed at different positions on the housing 11. For example, the housing 11 is provided with a mounting portion 113, which has a cylindrical structure. The piston 13 is slidably connected to the inner wall of the mounting portion 113, and the piston 13 and the housing 11 together define the first liquid storage chamber 111. The ventilation channel 12 and the mounting portion 113 are spaced apart.

[0066] When the piston 13 is in the third position of the housing 11, part of the piston 13 blocks the ventilation passage 12. Specifically, the piston 13 may partially cover the end of the ventilation passage 12 near the first liquid storage chamber 111 or be partially embedded in the ventilation passage 12.

[0067] As the piston 13 moves from the third position to the fourth position, the volume of the first liquid storage chamber 111 defined by the piston 13 and the housing 11 gradually decreases, causing the gas pressure in the first liquid storage chamber 111 to increase.

[0068] When the piston 13 moves to the fourth position, a gap may be generated between the ventilation channel 12 and the piston 13, or the ventilation channel 12 may be directly separated from the piston 13, so that when the gas pressure in the first liquid storage chamber 111 decreases during the suction process, the gas in the second liquid storage chamber 224 can be replenished into the first liquid storage chamber 111 through the ventilation channel 12.

[0069] Or, such as Figure 4 As shown, in some other embodiments, the ventilation channel 12 and the piston 13 may be located at the same position on the housing 11. For example, the housing 11 is provided with a mounting part 113, which has a through hole 1131 communicating with the first liquid storage chamber 111. The piston 13 is mounted on the mounting part 113, and part of the piston 13 extends into the first liquid storage chamber 111 through the through hole 1131.

[0070] Specifically, the mounting part 113 includes a side plate 1133 and a top plate 1132 connected to each other. The side plate 1133 is arranged circumferentially around the top plate 1132, that is, the side plate 1133 is arranged in a cylindrical shape around the top plate 1132. A through hole 1131 is provided on the top plate 1132. The first liquid storage chamber 111 is located on the side of the top plate 1132 away from the side plate 1133. A portion of the piston 13 is disposed in the cylindrical side plate 1133, and a portion of the piston 13 extends into the first liquid storage chamber 111 after passing through the through hole 1131.

[0071] The piston 13 includes a first structural member 131 and a second structural member 132. The first structural member 131 is connected to and slidably fitted with the mounting portion 113. The first structural member 131 is tightly fitted to and slidably connected to the inner sidewall of the side plate 1133, and there is a gap between the first structural member 131 and the top plate 1132. One end of the second structural member 132 is connected to the first structural member 131, and the other end of the second structural member 132 extends into the first liquid storage chamber 111 through the through hole 1131. The first structural member 131 and the second structural member 132 are fixedly connected, including but not limited to welding, threaded connection, etc.

[0072] In this embodiment, one end of the ventilation passage 12 is disposed on the piston 13, specifically on the first structural member 131 of the piston 13. The other end of the ventilation passage 12 is defined by the gap between the inner wall of the through hole 1131 and part of the outer wall of the piston 13. That is, the outer wall of the second structural member 132 and the inner wall of the through hole 1131 define a portion of the ventilation passage 12.

[0073] Optionally, along the direction in which the piston 13 moves into the first liquid storage chamber 111, the through hole 1131 is flared and stepped, and the shape of the second structural member 132 matches the shape of the through hole 1131.

[0074] Optionally, along the direction in which the piston 13 moves toward the first liquid storage chamber 111, the diameter of the through hole 1131 gradually increases, and the shape of the second structural member 132 matches the shape of the through hole 1131.

[0075] Furthermore, the ventilation passage 12 is at least partially defined by the gap between the mounting portion 113 and the piston 13. That is, the ventilation passage 12 includes the gap between the first structural member 131 and the top plate 1132.

[0076] In this embodiment, the first structural member 131 of the piston 13 can be driven by the supporting part 226, and drive the second structural member 132 to move synchronously from the third position to the fourth position. When the piston 13 is in the third position of the housing 11, the second structural member 132 is tightly fitted with the side wall of the through hole 1131, thus blocking the ventilation channel 12; as the piston 13 moves from the third position to the fourth position, the volume of the part extending into the first liquid storage chamber 111 gradually increases, thereby increasing the gas pressure in the first liquid storage chamber 111; when the piston 13 moves to the fourth position, a gap can be generated between the hole wall of the through hole 1131 and the second structural member 132, thus opening the ventilation channel 12.

[0077] Please continue reading. Figure 4 In some embodiments, a first sealing element 16 is provided between the outer side wall of the first structural member 131 and the inner side wall of the mounting portion 113.

[0078] Optionally, the first seal 16 can be fixed to the inner wall of the mounting portion 113, such as the inner wall of the side plate 1133. The first structural member 131 is in close contact with the first seal 16, and the first structural member 131 can slide relative to the first seal 16 and the mounting portion 113.

[0079] Alternatively, the first sealing element 16 can also be fixed on the first structural element 131. The first sealing element 16 is an O-ring. The first sealing element 16 is sleeved on the first structural element 131. The first sealing element 16 is tightly fitted with the mounting part 113, and the first sealing element 16 slides synchronously with the first structural element 131 relative to the mounting part 113.

[0080] In some embodiments, a second seal 17 is provided between the outer sidewall of the second structural member 132 and the inner sidewall of the mounting portion 113.

[0081] Optionally, the second seal 17 can be fixed to the inner wall of the mounting portion 113, such as the wall of the through hole 1131. When the piston 13 is in the third position, the second structural member 132 and the second seal 17 are in close contact; when the piston 13 is in the fourth position, there is a gap between the second structural member 132 and the second seal 17. Furthermore, the second structural member 132 can move relative to the second seal 17 and the mounting portion 113.

[0082] Alternatively, the second seal 17 can also be fixed on the second structural member 132. The second seal 17 is an O-ring, and the second seal 17 moves synchronously with the second structural member 132 relative to the mounting part 113.

[0083] The first sealing element 16 and the second sealing element 17 are made of easily compressible materials such as silicone or rubber. The first structural element 131 and the second structural element 132 are made of materials such as plastic or metal, and have high rigidity so that they can move under external force.

[0084] In some embodiments, the ventilation channel 12 extends in a meandering manner. As previously described, the ventilation channel 12 includes a gap between the first structural member 131 and the top plate 1132. The opposite sides of the first structural member 131 and the top plate 1132 can form mutually engaging convex and concave structures, thereby causing the gap between the first structural member 131 and the top plate 1132 to extend in a meandering manner. This increases the length and tortuosity of the flow path in the ventilation channel 12, effectively delaying the leakage of the liquid matrix in the first liquid storage chamber 111 through the ventilation channel 12 when the ventilation channel 12 is opened.

[0085] Please continue reading. Figure 4 In some embodiments, the liquid replenishment mechanism 10 further includes a reset member 15, which can drive the piston 13 to return to the state of blocking the ventilation passage 12 when the state between the liquid replenishment mechanism 10 and the atomizing mechanism 20 switches from a connected state to a disconnected state.

[0086] When the liquid replenishment mechanism 10 and the atomizing mechanism 20 are not connected, the piston 13 is held in the third position of the housing 11 by the action of the reset member 15. When the liquid replenishment mechanism 10 and the atomizing mechanism 20 are connected, the top holding part 226 pushes the piston 13 to move from the third position to the fourth position against the force of the reset member 15, and the piston 13 can be held in the fourth position by a pair of balanced forces applied by the top holding part 226 and the reset member 15. When the liquid replenishment mechanism 10 and the atomizing mechanism 20 switch from the connected state to the unconnected state, the piston 13 loses the force of the top holding part 226, and the reset member 15 drives the piston 13 to quickly return to the third position that blocks the ventilation channel 12, thereby ensuring that the ventilation channel 12 remains sealed in the unconnected state and effectively preventing accidental leakage of the liquid matrix in the first liquid storage chamber 111.

[0087] The reset member 15 can drive the piston 13 to move by its own elastic force. For example, the reset member 15 can be made of a spring, a metal sheet, or an elastic rubber block. In some embodiments, one end of the reset member 15 abuts against the housing 11, and the other end of the reset member 15 abuts against the piston 13. After pre-compression, the reset member 15 is assembled between the housing 11 and the piston 13. When the piston 13 loses the force of the supporting part 226, the reset member 15 restores its original shape through its own elastic deformation, causing the piston 13 to return to the third position.

[0088] The reset member 15 can also reset the piston 13 by magnetic attraction. For example, the reset member 15 is a magnetic element. The reset member 15 is fixed to at least one of the housing 11 and the piston 13. When the atomizing mechanism 20 and the liquid replenishment mechanism 10 are not connected, the housing 11 holds the piston 13 in the third position by magnetic attraction or repulsion.

[0089] By driving the piston 13 through the reset element 15 to close the ventilation channel 12, leakage of the liquid matrix in the first liquid storage chamber 111 through the ventilation channel 12 can be effectively prevented when the liquid replenishment mechanism 10 and the atomizing mechanism 20 are switched to an unconnected state, thus improving the sealing performance of the liquid replenishment mechanism 10. Furthermore, the piston 13 is automatically reset by driving the piston 13 through the reset element 15, reducing user operation steps and preventing liquid matrix leakage due to human negligence.

[0090] Please see Figure 2 In some embodiments, the position of the top holding portion 226 acting on the piston 13 corresponds to the position of the reset member 15. It is understood that when the liquid replenishment mechanism 10 is connected to the atomizing mechanism 20, the top holding portion 226 and the reset member 15 apply opposite forces to the piston 13. By setting the position of the top holding portion 226 acting on the piston 13 to correspond with the position of the reset member 15, the piston 13 is prevented from deflecting or jamming due to uneven force during movement.

[0091] Please see Figure 5 and Figure 6 , Figure 5 yes Figure 1 A schematic diagram of the external structure of the atomizing mechanism in the embodiment. Figure 6 yes Figure 1 A schematic diagram of the internal structure of the atomizing mechanism in the embodiment.

[0092] In some embodiments, the vent 221 and the support portion 226 are spaced apart, and the wall of the vent 221 and the support portion 226 are designed to work together on the piston 13. The end of the vent 221 can abut against the first structural member 131, and the thrust applied thereto cooperates with the force of the support portion 226 to ensure that the piston 13 moves smoothly in a predetermined direction, avoiding deflection or jamming caused by lateral forces.

[0093] In some embodiments, the wall of the vent 221 can serve as the support portion 226, that is, the vent 221 and the support portion 226 have the same structure, and the piston 13 is moved from the third position to the fourth position by relying solely on the wall of the vent 221.

[0094] In some embodiments, the depth direction of the vent 221 is consistent with the movement direction of the piston 13, and the outer wall of the vent 221 can be slidably connected to the first structural member 131, thereby reducing movement resistance.

[0095] Please see Figure 6 In some embodiments, the end of the vent 221 is covered with a waterproof and breathable membrane 21. The waterproof and breathable membrane 21 may be made of materials such as polytetrafluoroethylene, and its micropore diameter is smaller than the diameter of liquid matrix molecules but larger than the diameter of air molecules, which can prevent liquid matrix from penetrating while allowing air to pass through.

[0096] And / or, the end of the vent 221 is covered with a cotton product. The cotton product may be made of a liquid-absorbing polymer material, such as polyurethane foam or cellulose cotton, which absorbs the liquid matrix and blocks the pores through capillary action.

[0097] When the atomizing mechanism 20 is connected to the liquid replenishment mechanism 10, the ventilation channel 12 is opened simultaneously to form an airflow channel, accelerating the flow of the liquid matrix in the first liquid storage chamber 111 to the second liquid storage chamber 224.

[0098] When the liquid matrix in the second liquid storage chamber 224 reaches the vent 221, the micropores of the liquid matrix gradually become blocked due to the adhesion of the liquid matrix after contacting the waterproof and breathable membrane 21, or the pores of the cotton product close due to the expansion of the absorbed liquid. That is, when the liquid matrix in the second liquid storage chamber 224 rises to the vent 221, it blocks the airflow channel, thereby automatically terminating the ventilation process, thus slowing down the liquid transport efficiency and preventing excessive liquid matrix transport from the first liquid storage chamber 111 to the second liquid storage chamber 224, which could lead to liquid leakage.

[0099] Please continue reading. Figure 6 In some embodiments, the liquid inlet 222 and the air vent 221 are spaced apart, with the air vent 221 located near the top of the second liquid storage chamber 224 and the liquid inlet 222 located near the bottom of the second liquid storage chamber 224.

[0100] In this application embodiment, all directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0101] Specifically, the chamber 22 has a suction nozzle 227 for performing suction actions. The suction nozzle 227, the vent 221, and the liquid inlet 222 are arranged sequentially at intervals, and the distance from the vent 221 to the suction nozzle 227 is less than the distance from the liquid inlet 222 to the suction nozzle 227. Therefore, when the user is suctioning, the vent 221 is positioned closer to the top of the second liquid storage chamber 224, while the liquid inlet 222 is positioned closer to the bottom of the second liquid storage chamber 224.

[0102] The distance between the liquid inlet 222 and the air exchange 221 is greater than or equal to 1.5cm. The specific distance between the liquid inlet 222 and the air exchange 221 can be 1.5cm, 2cm, 2.5cm or 3cm. This application embodiment does not make a specific limitation on this.

[0103] Correspondingly, the liquid outlet 112 is located near the bottom of the first liquid storage chamber 111, and the ventilation channel 12 is located near the top of the first liquid storage chamber 111. This arrangement allows the liquid matrix to enter the second liquid storage chamber 224 from the bottom of the first liquid storage chamber 111 through the gravity of the liquid matrix in conjunction with the movement of the piston 13. At the same time, it can reduce the risk of the liquid matrix in the first liquid storage chamber 111 flowing into the ventilation channel 12 and clogging the ventilation channel 12, thereby maintaining the gas exchange function of the ventilation port 221 and the ventilation channel 12.

[0104] Please continue reading. Figure 6 In some embodiments, the top support 226, the vent 221 and the liquid inlet 222 are all spaced apart, and the distance between the liquid inlet 222 and the vent 221 is greater than the distance between the top support 226 and the vent 221.

[0105] The top support 226 serves to support and push the piston 13 when the atomizing mechanism 20 is connected to the liquid replenishment mechanism 10. The vent 221 and the liquid inlet 222 are responsible for gas exchange and liquid input, respectively. The three are spatially independent. The larger distance between the liquid inlet 222 and the vent 221 can effectively delay the backflow phenomenon of the liquid replenishment mechanism 10 during the liquid supply process, so that the liquid matrix flows more stably to the second liquid storage chamber 224.

[0106] In some embodiments, the ventilation port 221 and the liquid inlet port 222 extend along the length direction perpendicular to the atomizing mechanism 20. The chamber 22 also has an independent air inlet channel 223, which extends along the length direction of the atomizing mechanism 20 and connects external gas with the second liquid storage chamber 224. When the atomizing mechanism 20 is connected to the liquid replenishment mechanism 10, the first liquid storage chamber 111 and the second liquid storage chamber 224 are arranged side-by-side along the width direction of the atomizing mechanism 20. This optimizes the space of the atomizing device, making the overall structure more compact.

[0107] Please continue reading. Figure 6 In some embodiments, the second liquid storage chamber 224 is provided with a liquid storage element 23 and an atomizing core assembly 228 for heating the aerosol matrix, with the liquid storage element 23 covering the periphery of the atomizing core assembly 228.

[0108] The atomizing core assembly 228 may include a ceramic heating element with good thermal conductivity and stability, capable of rapidly and uniformly heating the liquid matrix, causing it to quickly vaporize into an aerosol. Alternatively, the atomizing core assembly 228 may include a metal heating wire, through which heat is generated by passing an electric current through the heating wire to heat the liquid matrix.

[0109] The liquid reservoir 23 is used to guide the liquid matrix into the atomizing core assembly 228. The liquid reservoir 23 is made of, but is not limited to, porous materials that easily absorb water, such as fibers or cotton cores. In some embodiments, the liquid reservoir 23 has a guide surface 231, which faces the end of the liquid inlet 222, and the guide surface 231 has a gap between the inner wall of the second liquid reservoir 224. It is understood that the liquid inlet 222 not only serves to transport the liquid matrix between the first liquid reservoir 111 and the second liquid reservoir 224, but also enables air exchange between them. During the operation of the atomizing device, the liquid reservoir 23 is prone to thermal expansion, and the guide surface 231 of the liquid reservoir 23 may not completely adhere to the inner wall of the second liquid reservoir 224, meaning the liquid reservoir 23 does not completely fill the second liquid reservoir 224. The portion of the liquid storage component 23 near the liquid inlet 222 has ample expansion space to prevent the liquid storage component 23 from blocking the liquid inlet 222 when it expands due to heat, thus affecting the liquid supply rate and air exchange efficiency of the first liquid storage chamber 111 and the second liquid storage chamber 224.

[0110] Please combine Figure 6 and Figure 7 , Figure 7 yes Figure 1 A partial structural diagram of the atomizing mechanism in the embodiment is shown. In some embodiments, a ventilation groove 229 is provided on the inner wall of the second liquid storage chamber 224. One end of the ventilation groove 229 is connected to the liquid inlet hole 222, and the other end is located near the ventilation hole 221. The ventilation groove 229 can balance the air pressure between the ventilation hole 221 and the liquid inlet hole 222, preventing liquid from accumulating at the bottom of the second liquid storage chamber 224 or forming air resistance. This allows the liquid matrix entering the bottom of the second liquid storage chamber 224 through the liquid inlet hole 222 to be effectively absorbed by the liquid storage component 23 and transferred to the atomizing core assembly 228, thereby improving the overall atomization efficiency and liquid supply stability.

[0111] In some embodiments, at least a portion of the ventilation groove 229 is located between the guide surface 231 and the inner wall of the second liquid storage chamber 224, such that the ventilation groove 229 communicates with the liquid inlet 222. In practical applications, the number of ventilation grooves 229 can be reasonably set according to the size of the second liquid storage chamber 224 and the working requirements of the atomizing mechanism 20.

[0112] Please see Figure 3 and Figure 5 In some embodiments, the liquid outlet 112 is provided with a third seal 14, which has a cross opening or a straight opening.

[0113] When the atomizing mechanism 20 is connected to the liquid replenishment mechanism 10, the wall of the liquid inlet 222 is defined to pass through the third seal 14 and be inserted into the liquid outlet 112 so that the liquid inlet 222 and the liquid outlet 112 are in a sealed communication.

[0114] The opening structure of the third seal 14 allows the liquid inlet 222 to pass through while maintaining a tight seal when connected to the third seal 14, ensuring rapid transfer of the liquid matrix under pressure. In a specific embodiment, the third seal 14 can be a sealing component made of silicone or rubber, and the liquid inlet 222 can be a tubular structure made of metal or plastic.

[0115] In some embodiments, during the connection process between the replenishing mechanism 10 and the atomizing mechanism 20, the replenishing mechanism 10 has a first position and a second position relative to the atomizing mechanism 20. Specifically, when the replenishing mechanism 10 is in the first position, the inlet port 222 aligns with the outlet port 112, allowing the first liquid storage chamber 111 to communicate with the second liquid storage chamber 224; the venting port 221 aligns with the venting channel 12, and the venting channel 12 remains closed. When the replenishing mechanism 10 moves from the first position to the second position, the supporting portion 226 acts on the replenishing mechanism 10, increasing the air pressure in the first liquid storage chamber 111; the venting channel 12 switches to the open state.

[0116] In this embodiment, before the ventilation channel 12 is opened, the liquid inlet 222 and the liquid outlet 112 are connected to form a liquid channel, and the ventilation port 221 is connected to the ventilation channel 12 to form an airflow channel. This avoids liquid leakage or airflow interference. Subsequently, the top holding part 226 acts on the piston 13 and drives the piston 13 to move, causing the air pressure inside the first liquid storage chamber 111 to rise, thereby accelerating the flow of the liquid matrix, significantly shortening the liquid supply time and reducing the risk of core clogging. During the movement of the top holding part 226, the ventilation channel 12 is triggered to open.

[0117] In some embodiments, the opening of the ventilation channel 12 and the increase of air pressure in the first liquid storage chamber 111 can be carried out simultaneously.

[0118] In other embodiments, the air pressure in the first liquid storage chamber 111 can be increased first, and then the ventilation channel 12 can be opened. In this way, in the initial stage of the connection between the atomizing mechanism 20 and the liquid replenishing mechanism 10, the liquid matrix in the first liquid storage chamber 111 can quickly respond to the air pressure change and enter the second liquid storage chamber 224. After the atomizing mechanism 20 and the liquid replenishing mechanism 10 are connected in place, the gas balance between the first liquid storage chamber 111 and the second liquid storage chamber 224 can be achieved through the ventilation channel 12 and the ventilation hole 221 to maintain the stable output of the liquid matrix.

[0119] Please see Figure 4 and Figure 6In some embodiments, when the fluid replenishment mechanism 10 is in the first position, the vent 221 and the vent channel 12 are sealed together.

[0120] Specifically, the first structural member 131 has a receiving groove 133. One end of the ventilation channel 12 is located on the bottom wall of the receiving groove 133. The wall of the ventilation hole 221 can be inserted into the receiving groove 133. A fourth sealing member 24 is provided between the outer wall of the ventilation hole 221 and the inner wall of the receiving groove 133. The fourth sealing member 24 can be fixed to the inner wall of the receiving groove 133. During the process of inserting the outer wall of the ventilation hole 221 into the first structural member 131, the outer wall of the ventilation hole 221 and the fourth sealing member 24 are closely fitted and slide relative to each other. Alternatively, the fourth sealing member 24 can also be fixed to the outer wall of the ventilation hole 221. The fourth sealing member 24 is an O-ring. The fourth sealing member 24 is sleeved on the outer wall of the ventilation hole 221. During the process of inserting the outer wall of the ventilation hole 221 into the first structural member 131, the fourth sealing member 24 and the first structural member 131 are closely fitted and slide relative to each other.

[0121] In some embodiments, the depth direction of the vent 221 is consistent with the movement direction of the piston 13, and the outer wall of the vent 221 can be slidably connected to the inner wall of the receiving groove 133, thereby reducing movement resistance.

[0122] In some embodiments, the piston 13 may not be included in the liquid replenishment mechanism 10; instead, the top support 226 may serve as the piston 13. For example, the housing 11 includes a connecting channel communicating with the first liquid storage chamber 111. When the liquid replenishment mechanism 10 is not connected to the atomizing mechanism 20, the connecting channel can be sealed by a sealing structure, which may be configured with reference to the third seal 14 described above. When the liquid replenishment mechanism 10 is connected to the atomizing mechanism 20, the top support 226 is inserted into the connecting channel and seals with the sealing structure. Thus, as the atomizing mechanism 20 and the liquid replenishment mechanism 10 gradually approach and connect, the volume of the top support 226 extending into the first liquid storage chamber 111 through the connecting channel gradually increases, thereby increasing the air pressure in the first liquid storage chamber 111 and causing the liquid matrix in the first liquid storage chamber 111 to flow out rapidly through the outlet 112.

[0123] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
