[0001] This application relates to the field of atomization technology, specifically to an atomizer and an electronic atomization device. Background Technology

[0002] An atomizer is an electronic device that heats a liquid matrix and converts it into an aerosol for users to inhale. Some atomizers on the market have a refill port, allowing users to refill the liquid matrix in the reservoir when it runs out, thus enabling the atomizer to be reused. However, conventional atomizers usually have the refill port on the outside, posing a risk of accidental opening and subsequent liquid matrix leakage. Utility Model Content

[0003] This application provides an atomizer and an electronic atomizing device to solve the problem that the liquid injection port is designed externally, which can easily lead to accidental opening and leakage of the liquid matrix.

[0004] In some embodiments, the atomizer includes a body and a shielding member movable relative to the body. The body includes a liquid reservoir assembly, an atomizing assembly, and a liquid guiding assembly. The liquid reservoir assembly defines a first liquid reservoir chamber for storing a liquid matrix; the atomizing assembly includes a second liquid reservoir chamber for storing the liquid matrix and an atomizing element for atomizing the liquid matrix originating from the second liquid reservoir chamber to generate an aerosol; the liquid guiding assembly is provided with a liquid guiding channel communicating between the first liquid reservoir chamber and the second liquid reservoir chamber to guide the liquid matrix in the first liquid reservoir chamber into the second liquid reservoir chamber. The liquid reservoir assembly further includes an injection port for injecting the liquid matrix into the first liquid reservoir chamber, and the shielding member is configured to have a first state of covering the injection port and a second state of exposing the injection port.

[0005] In some embodiments, the volume of the first liquid storage chamber is greater than the volume of the second liquid storage chamber.

[0006] In some embodiments, the second liquid storage chamber is provided with a liquid storage device for storing the liquid matrix.

[0007] In some embodiments, the fluid guiding assembly includes a first seal for sealing the first fluid reservoir and a base for supporting the first seal, the base including a fluid guiding column extending away from the first fluid reservoir, the fluid guiding channel being defined by the fluid guiding column.

[0008] In some embodiments, the shielding member includes a nozzle having an outlet for aerosol to escape from the atomizer.

[0009] In some embodiments, the atomizing component includes a first atomizing component and a second atomizing component, and the body defines a first airflow channel for discharging aerosol in the first atomizing component and a second airflow channel for discharging aerosol in the second atomizing component.

[0010] The first liquid storage chamber is provided in two, and the two first liquid storage chambers are arranged at intervals. The liquid injection hole includes a first liquid injection hole and a second liquid injection hole that are correspondingly connected to the two first liquid storage chambers.

[0011] The nozzle is configured to cover the first injection hole and the second injection hole in the first state and selectively maintain communication with one of the first airflow channel and the second airflow channel; and to expose the first injection hole and the second injection hole in the second state and keep them offset from both the first airflow channel and the second airflow channel.

[0012] In some embodiments, the suction nozzle is provided with a retaining mechanism that can interfere with the main body, so that the suction nozzle can be stably held in the first state.

[0013] In some embodiments, the main body is provided with a second seal, which can selectively block or open the injection hole.

[0014] In some embodiments, the suction nozzle is rotatably connected to the body.

[0015] In some embodiments, an elastic element is provided between the nozzle and the body, the elastic element being configured such that the nozzle provides a preload force toward the body, the direction of the preload force being in the same direction as the rotation axis of the nozzle.

[0016] In some embodiments, the main body is provided with a bushing, the suction nozzle includes a rotating shaft and a limiting part fixedly connected to the rotating shaft, the rotating shaft passes through the bushing and is rotatably connected to the bushing, the elastic element is sleeved outside the rotating shaft, and the two ends of the elastic element abut against the opposite sides of the limiting part and the bushing, respectively.

[0017] In some embodiments, an electronic atomizing device is provided, including the atomizer described above, and a power supply component for connecting to the atomizer and providing electrical power to the atomizer.

[0018] The atomizer provided in this application embodiment physically isolates the injection port by setting a movable shield, allowing the user to quickly expose the injection port when liquid injection is needed, while maintaining a seal when not in use. This effectively reduces the probability of the injection port being accidentally opened and prevents leakage of the liquid matrix during transportation or use. The liquid guiding channel allows the liquid matrix to be transported from the first liquid storage chamber to the second liquid storage chamber, ensuring that the atomizing element is always in a wetted state, improving atomization efficiency and operational stability.

[0038] 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.

[0039] 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 as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of components in a specific posture (as shown in the figures). If the specific posture changes, the directional indication will also change accordingly. 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.

[0040] 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.

[0041] Please see Figure 1 , Figure 1 This is a schematic diagram of the external structure of an electronic atomizing device in some embodiments of this application. Embodiments of this application provide an electronic atomizing device, including an atomizer 100 and a power supply assembly 200. The atomizer 100 is used to heat a liquid matrix to generate an aerosol for inhalation by a user. The power supply assembly 200 is connected to the atomizer 100 and provides electrical energy to the atomizer 100.

[0042] The power supply assembly 200 can control the operating state of the atomizer 100. For example, the power supply assembly 200 can control the atomizer 100 to heat the liquid matrix to generate an aerosol or stop heating based on the user's inhalation action. The atomizer 100 and the power supply assembly 200 can be fixedly connected or detachably connected. When the atomizer 100 and the power supply assembly 200 are detachably connected, if the liquid matrix in the atomizer 100 is completely consumed, the user can easily separate the atomizer 100 from the power supply assembly 200. The electronic atomization device can continue to be used after replacing the atomizer 100, allowing the power supply assembly 200 to be used multiple times, thereby reducing the user's operating costs.

[0043] Please see Figure 2 and Figure 3 , Figure 2 yes Figure 1 An explosion diagram of the atomizer in the embodiment. Figure 3 yes Figure 1 A schematic diagram of the internal structure of the atomizer in this embodiment. The atomizer 100 includes a main body 10 and a shielding member 20. The main body 10 includes a liquid storage assembly 11, an atomizing assembly 12, and a liquid guiding assembly 13. The liquid storage assembly 11 defines a first liquid storage chamber 111 for storing a liquid matrix. The atomizing assembly 12 includes a second liquid storage chamber 121 for storing a liquid matrix, and an atomizing element 122 for atomizing the liquid matrix originating from the second liquid storage chamber 121 to generate an aerosol. The liquid guiding assembly 13 is provided with a liquid guiding channel 1322 communicating between the first liquid storage chamber 111 and the second liquid storage chamber 121, to guide the liquid matrix in the first liquid storage chamber 111 to the second liquid storage chamber 121.

[0044] The liquid storage assembly 11 also includes an injection hole 112 for injecting the liquid matrix into the first liquid storage chamber 111. The shielding member 20 is configured to have a first state covering the injection hole 112 and a second state exposing the injection hole 112. That is, the shielding member 20 is movably disposed on the main body 10, covering the injection hole 112 in the first state and exposing the injection hole 112 in the second state. The injection hole 112 can be opened and closed using a sliding shielding member 20 or a rotating shielding member 20. By physically isolating the injection hole 112 with the shielding member 20, the probability of the injection hole 112 being accidentally opened is effectively reduced, preventing leakage of the liquid matrix during transportation or use.

[0045] Please see Figure 2 In some embodiments, the shielding member 20 includes a mouthpiece 21 for the user to perform a suction action. The mouthpiece 21 is provided with an air outlet 211 for the aerosol to escape from the atomizer 100. The main body 10 defines an airflow channel 14 for discharging the aerosol in the atomizer 100. The airflow channel 14 is connected to the atomizing element 122, so that the aerosol generated by the atomization of the atomizing element 122 can enter the airflow channel 14 and be transported along the airflow channel 14.

[0046] In one embodiment, the suction nozzle 21 is configured to slide relative to the body 10 between a first position and a second position. When the suction nozzle 21 is in the first position, the suction nozzle 21 covers the injection hole 112 and the airflow channel 14 is connected to the air outlet 211 of the suction nozzle 21. When the suction nozzle 21 is in the second position, the suction nozzle 21 opens the injection hole 112 and the airflow channel 14 is offset from the injection hole 112.

[0047] In one embodiment, the suction nozzle 21 is configured to slide relative to the body 10 between a first position and a second position, and the rotation axis of the suction nozzle 21 coincides with the axis of the airflow channel 14, with the air outlet 211 of the suction nozzle 21 maintaining communication with the airflow channel 14. When the suction nozzle 21 is in the first position, the suction nozzle 21 blocks the injection hole 112; when the suction nozzle 21 is in the second position, the suction nozzle 21 opens the injection hole 112.

[0048] In some embodiments, the nozzle 21, the liquid storage component 11, the liquid guiding component 13, and the atomizing component 12 of the atomizer 100 are arranged sequentially along their length, so that during the user's inhalation process, the liquid matrix in the first liquid storage chamber 111 can smoothly enter the second liquid storage chamber 121 through the liquid guiding channel 1322 under the action of gravity.

[0049] Please continue reading. Figure 3In some embodiments, the volume of the first liquid storage chamber 111 is larger than the volume of the second liquid storage chamber 121. The first liquid storage chamber 111, as the main liquid storage space, has a larger volume to store more liquid matrix, while the second liquid storage chamber 121 can be designed with a relatively smaller volume according to the working requirements of the atomizing component 12, to ensure that the liquid matrix can be supplied to the atomization process more accurately, so that the liquid matrix can be consumed by atomization more quickly, reducing the possibility of accumulation in the chamber and leakage.

[0050] Meanwhile, the second liquid storage chamber 121 has a small volume and a limited amount of liquid inside. Even in some unexpected situations, such as a brief inversion, not too much liquid matrix will flow instantaneously to the parts that may leak due to gravity. For example, when the electronic atomizing device is not in operation, the liquid matrix in the second liquid storage chamber 121 may leak through the airflow channel 14 and the air outlet 211 of the nozzle 21.

[0051] In some embodiments, a liquid storage component 123 for storing a liquid matrix is ​​provided in the second liquid storage chamber 121. The liquid storage component 123 can be made of porous materials such as cotton core, fiber, non-woven fabric, fiberglass rope, or ceramic, which can adsorb and fix the liquid matrix, effectively preventing the liquid from sloshing or flowing poorly in the second liquid storage chamber 121. At the same time, the liquid storage component 123 can also buffer the supply rate of the liquid matrix to a certain extent, making the atomization process more stable, reducing the adverse effects of too much or too little instantaneous liquid supply on atomization quality, and reducing the risk of leakage caused by unstable liquid flow.

[0052] Please see Figure 2 and Figure 3 In some embodiments, the liquid guiding assembly 13 includes a first seal 131 and a base 132. The first seal 131 seals the first liquid storage chamber 111, and the base 132 provides support for the first seal 131. Specifically, the first seal 131 can be sleeved on the base 132, and the first seal 131 is in close contact with the inner wall of the first liquid storage chamber 111. The first seal 131 can be made of rubber or silicone.

[0053] The base 132 includes a liquid guide column 1321 extending away from the first liquid storage chamber 111, and a liquid guide channel 1322 is defined by the liquid guide column 1321. The base 132 can be made of plastic or metal. The liquid guide column 1321 can be designed as a cylindrical, conical, or stepped hole structure, and the cross-section of the liquid guide channel 1322 can be circular or irregular.

[0054] Understandably, the flow rate of the liquid matrix can be controlled by adjusting the length and diameter of the liquid guiding column 1321. For example, the diameter of the end of the liquid guiding channel 1322 near the first liquid storage chamber 111 is larger than the diameter of the end of the liquid guiding channel 1322 near the second liquid storage chamber 121, thus forming a gradient pressure regulation from the first liquid storage chamber 111 to the second liquid storage chamber 121. When the liquid matrix flows from the larger volume of the first liquid storage chamber 111 into the liquid guiding channel 1322, the larger diameter at the inlet end enables initial buffering and flow stabilization. Subsequently, as it flows towards the end of the liquid guiding channel 1322 with a gradually decreasing diameter, the flow rate of the liquid matrix gradually increases to meet the requirements of the smaller volume of the second liquid storage chamber 121 for liquid supply accuracy. This avoids the pressure shock that may occur when the first liquid storage chamber 111 directly supplies liquid to the second liquid storage chamber 121, and ensures that the second liquid storage chamber 121 always maintains a relatively stable liquid level, thereby providing a continuous and uniform supply of liquid matrix to the subsequent atomizing element 122 and effectively improving atomization efficiency.

[0055] Please combine Figure 3 and Figure 4 , Figure 4 yes Figure 1 Another exploded view of the atomizer in the embodiment. In some embodiments, the atomizing component 12 includes a first atomizing component 124 and a second atomizing component 125, and the body 10 defines a first airflow channel 141 for discharging aerosol in the first atomizing component 124 and a second airflow channel 142 for discharging aerosol in the second atomizing component 125.

[0056] Two first liquid storage chambers 111 are provided, and the two first liquid storage chambers 111 are arranged at intervals. The injection hole 112 includes a first injection hole 1121 and a second injection hole 1122 that are correspondingly connected to the two first liquid storage chambers 111.

[0057] In some embodiments, different flavored liquid bases can be injected into the two first liquid storage chambers 111 through the first injection port 1121 and the second injection port 1122, respectively, to meet the user's need for multiple flavor combinations. The two spaced-apart first liquid storage chambers 111 can independently store liquid bases, preventing mixing of different flavored liquid bases during storage and ensuring the purity of each flavor. This dual-liquid-chamber structure design not only increases the diversity of liquid base flavors but also allows for flexible adjustment of the liquid supply method according to user preferences, enhancing the applicability and personalization of the atomizer 100.

[0058] Please see Figure 3 and Figure 5 , Figure 5 yes Figure 1A schematic diagram of the shielding component of the atomizer in the embodiment. In some embodiments, the nozzle 21 is configured to cover the first injection hole 1121 and the second injection hole 1122 in a first state, and selectively maintain communication with one of the first airflow channel 141 and the second airflow channel 142; and to expose the first injection hole 1121 and the second injection hole 1122 in a second state, and to remain offset from both the first airflow channel 141 and the second airflow channel 142.

[0059] Specifically, the shielding member 20 also includes an isolation portion 22, which is fixed to the side of the suction nozzle 21 facing the main body 10 and spaced apart from the air outlet 211. The suction nozzle 21 is configured to move relative to the main body 10 between a first position, a second position, and a third position.

[0060] When the suction nozzle 21 is in the first position, the suction nozzle 21 covers the first injection hole 1121 and the second injection hole 1122, the air outlet 211 of the suction nozzle 21 is connected to the first airflow channel 141, and the isolation part 22 is connected to the second airflow channel 142.

[0061] When the suction nozzle 21 is in the second position, the suction nozzle 21 covers the first injection hole 1121 and the second injection hole 1122, the air outlet 211 of the suction nozzle 21 is connected to the second airflow channel 142, and the isolation part 22 is connected to the first airflow channel 141.

[0062] When the suction nozzle 21 is in the third position, the suction nozzle 21 opens the first injection hole 1121 and the second injection hole 1122, while the air outlet 211 of the suction nozzle 21 is staggered from the first airflow channel 141 and the second airflow channel 142.

[0063] In some embodiments, the nozzle 21 is provided with a retaining mechanism 40 that can interfere with the body 10, so that the nozzle 21 can be stably held in the first state.

[0064] The retaining mechanism 40 on the nozzle 21 achieves a fixing effect through mechanical interference with the main body 10. A snap-fit ​​structure or elastic abutment component can be used; for example, an elastic protrusion can be provided on the side wall of the nozzle 21, and a corresponding groove can be provided on the main body 10, achieving engagement through elastic deformation. Alternatively, a magnetic adsorption method can be used, where a built-in magnetic element in the nozzle 21 attracts the metal parts of the main body 10.

[0065] Please see Figure 3 In one embodiment, the holding mechanism 40 includes a first magnetic element 41 and a second magnetic element 24 on the main body 10. When the suction nozzle 21 is in the first position, the first magnetic element 41 and the second magnetic element 24 are connected and magnetically attracted to each other. The holding mechanism 40 also includes a third magnetic element 42. When the suction nozzle 21 is in the second position, the third magnetic element 42 is connected and magnetically attracted to the second magnetic element 24.

[0066] In one embodiment, the holding mechanism 40 includes a first magnetic element 41, and a second magnetic element 24 is provided on the main body 10. When the suction nozzle 21 is in the first position, the first magnetic element 41 and the second magnetic element 24 are mated and magnetically attracted to each other. A fourth magnetic element 25 is provided on the main body 10. When the suction nozzle 21 is in the second position, the first magnetic element 41 and the fourth magnetic element 25 are mated and magnetically attracted to each other.

[0067] In one embodiment, the holding mechanism 40 includes a first magnetic element 41 and a third magnetic element 42, and the main body 10 is provided with a second magnetic element 24 and a fourth magnetic element 25. When the suction nozzle 21 is in the first position, the first magnetic element 41 and the second magnetic element 24 are mated and magnetically attracted to each other, and the third magnetic element 42 and the fourth magnetic element 25 are mated and magnetically attracted to each other. When the suction nozzle 21 is in the second position, the first magnetic element 41 and the fourth magnetic element 25 are mated and magnetically attracted to each other, and the third magnetic element 42 and the second magnetic element 24 are mated and magnetically attracted to each other.

[0068] It is understandable that the first magnetic component 41, the second magnetic component 24, the third magnetic component 42 and the fourth magnetic component 25 can be permanent magnets or made of metal materials with magnetic adsorption capabilities, as long as they can meet the corresponding magnetic adsorption capabilities.

[0069] In some embodiments, the main body 10 is provided with a second sealing element 50, which can selectively block or open the injection hole 112. The second sealing element 50 can be made of an elastic material, such as silicone or rubber, and achieves a sealing effect through compression deformation. Multiple second sealing elements 50 can be provided to block the first injection hole 1121 and the second injection hole 1122 respectively.

[0070] Please see Figure 2 and Figure 3 In some embodiments, the nozzle 21 is rotatably connected to the body 10.

[0071] An elastic element 30 is provided between the suction nozzle 21 and the main body 10. The elastic element 30 provides a preload force to the suction nozzle 21 towards the main body 10, and the direction of the preload force is the same as the rotation axis of the suction nozzle 21. The elastic element 30 can be a coil spring, a leaf spring, or an elastic rubber component, which generates a restoring force through compression or deformation. The coaxial preload force provided by the elastic element 30 enables the suction nozzle 21 to be self-adaptive during rotation, maintaining close contact with the main body 10 even after multiple uses. This prevents structural wear caused by repeated rotation of the suction nozzle 21, and thus prevents airflow leakage or structural instability caused by loose connection between the suction nozzle 21 and the main body 10. The elastic element 30 can be compressed, allowing the suction nozzle 21 to have room for movement in the direction of its own rotation axis, and also preventing the suction nozzle 21 from jamming during rotation.

[0072] Specifically, the main body 10 is provided with a bushing 15, and the suction nozzle 21 includes a rotating shaft 212 and a limiting part 23 fixedly connected to the rotating shaft 212. The rotating shaft 212 is rotatably connected to the bushing 15. The rotating shaft 212 passes through the bushing 15 from the outside, and the limiting part 23 is located on the inside of the bushing 15 and fixedly connected to the rotating shaft 212, thereby preventing the suction nozzle 21 from disengaging from the bushing 15.

[0073] The elastic element 30 is sleeved on the outside of the rotating shaft 212, and its two ends abut against the opposite sides of the limiting part 23 and the bushing 15, respectively. The elastic element 30 is a pre-compressed spring. Through the elastic element 30 abutting against the limiting part 23, the limiting part 23 transmits the elastic force to the suction nozzle 21, so that the suction nozzle 21 always has a tendency to move closer to the main body 10.

[0074] 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.
