Description

Technical Field

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

[0002] During transportation, existing electronic atomizing devices are prone to leakage of the atomizing medium due to sealing issues between the oil guide components and other parts. Oil-wick separation technology helps improve this situation. Oil-wick separation technology involves sealing the lower liquid channel of the atomizing component during transportation, thereby reducing leakage. In an electronic atomizing device in oil-wick separation mode, the lower liquid channel is blocked, and the atomizing component does not receive sufficient liquid. Dragging in this state can cause dry burning, resulting in a burnt or unpleasant odor. Utility Model Content

[0003] The purpose of this application is to provide an electronic atomizing device to solve the technical problem in the prior art where an electronic atomizing device in the oil-wick separation state will dry-burn when it is accidentally started.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: An electronic atomizing device is provided, comprising a liquid storage chamber, an atomizing component, and a mouthpiece. The mouthpiece has an air outlet channel, the liquid storage chamber has a liquid storage cavity, and the atomizing component has a liquid dispensing channel. Liquid in the liquid storage cavity is supplied to the atomizing component through the liquid dispensing channel. The electronic atomizing device also has an auxiliary air duct, the air duct inlet of which is connected to the external atmosphere, and the air duct outlet of which is connected to the air outlet channel.

[0005] The electronic atomizing device has a first state and a second state. In the first state, the liquid lowering channel is connected to the liquid storage chamber, and the air inlet is disconnected from the air outlet. In the second state, the liquid lowering channel is disconnected from the liquid storage chamber, and the air inlet is connected to the air outlet.

[0006] In some embodiments, in the first state, the suction nozzle abuts against the liquid storage tank to disconnect the airway inlet from the airway outlet;

[0007] In the second state, the nozzle and the liquid storage tank have a first gap, the first gap connecting the airway outlet and the airway inlet.

[0008] In some embodiments, the liquid storage chamber and the atomizing component can slide relative to each other along the axial direction to switch between the first state and the second state, and the nozzle is connected to the atomizing component and moves synchronously.

[0009] In some embodiments, the liquid storage tank is equipped with a first seal, and in the first state, the suction nozzle abuts against the first seal; in the second state, the first gap is formed between the suction nozzle and the first seal.

[0010] In some embodiments, the auxiliary airway includes a connecting channel at least partially formed in the mouthpiece, the connecting channel communicating with the air outlet through the airway outlet; in the second state, the connecting channel communicating with the airway inlet through the first gap.

[0011] In some embodiments, the top end of the atomizing component is interference-fitted into the mouthpiece; a second gap communicating with the connecting channel is formed between the inner peripheral wall of the mouthpiece and the outer peripheral wall of the atomizing component; in the second state, the second gap communicates with the airway inlet through the first gap.

[0012] In some embodiments, the connection channel is formed in the nozzle;

[0013] Alternatively, the nozzle and the atomizing component together enclose the connection channel.

[0014] In some embodiments, the liquid storage tank has a receiving cavity communicating with the liquid storage chamber, and the bottom end of the suction nozzle is movably disposed in the receiving cavity; in the second state, the airway outlet communicates with the receiving cavity through the first gap, and the receiving cavity communicates with the airway inlet.

[0015] In some embodiments, the airway inlet is formed on the outer peripheral wall of the mouthpiece;

[0016] Alternatively, the air inlet is formed on the outer peripheral wall of the liquid storage tank;

[0017] Alternatively, the airway inlet is formed between the liquid storage tank and the nozzle.

[0018] In some embodiments, the electronic atomizing device further includes a main housing, which is sleeved at the connection between the nozzle and the liquid storage chamber. The main housing has an assembly port, from which the nozzle extends. A third gap exists between the outer peripheral wall of the nozzle and the inner peripheral wall of the assembly port, and the air passage inlet communicates with the third gap.

[0019] The beneficial effects of the electronic atomizing device provided in this application are as follows: By additionally setting an auxiliary airway on the basis of the main airway, in the second state, the outlet of the auxiliary airway is connected to the mouthpiece, the inlet of the auxiliary airway is connected to the outside atmosphere, and the inlet of the auxiliary airway is connected to the outlet. When the user inhales from the mouthpiece, the outside atmosphere flows to the mouthpiece through the main airway and the auxiliary airway respectively. The auxiliary airway 102 can share the airflow of the main airway, reducing the possibility of the airflow sensor being falsely activated. At the same time, by designing the airflow path of the auxiliary airway to be smaller than that of the main airway, the outside gas can mainly flow to the mouthpiece through the auxiliary airway, further reducing the possibility of the airflow sensor being falsely activated and avoiding the dry burning phenomenon of the atomizing component.

Detailed Implementation

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0033] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] As described in the background section, the oil-wick separation technology refers to sealing the lower liquid channel of the atomizing component during transportation to reduce leakage of the atomizing medium. Because the lower liquid channel of an electronic atomizing device in the oil-wick separation state is blocked, the atomizing component does not receive sufficient liquid. If the user inhales through the mouthpiece at this time, the atomizing component will dry-burn due to insufficient liquid supply, resulting in a burnt or unpleasant odor.

[0036] To address the aforementioned issues, this application provides an electronic atomizing device. By additionally providing an auxiliary airway 102, when the electronic atomizing device is in its second state, the auxiliary airway 102 connects the mouthpiece 300 to the external atmosphere. At this time, if the user inhales through the mouthpiece 300, the external atmosphere will enter the electronic atomizing device from both the main airway 101 and the auxiliary airway 102. Since the auxiliary airway 102 does not pass through the airflow sensor, the risk of the airflow sensor being falsely activated can be reduced, thus reducing the occurrence of dry burning.

[0037] Please see Figures 1 to 4 The electronic atomizing device provided in the embodiments of this application will now be described.

[0038] The electronic atomizing device includes a liquid storage tank 100, an atomizing component 200, and a mouthpiece 300. The liquid storage tank 100 has a liquid storage cavity 110, and the atomizing component 200 has a liquid discharge channel 210 through which liquid in the liquid storage cavity 110 is supplied to the atomizing component 200. The electronic atomizing device also has an auxiliary airway 102, with its airway inlet 1022 connected to the outside atmosphere and its airway outlet 1021 connected to the mouthpiece 300. The electronic atomizing device has a first state and a second state. In the first state, the liquid discharge channel 210 is connected to the liquid storage cavity 110, and the airway inlet 1022 of the auxiliary airway 102 is disconnected from the airway outlet 1021. In the second state, the liquid discharge channel 210 is disconnected from the liquid storage cavity 110, and the airway inlet 1022 of the auxiliary airway 102 is connected to the airway outlet 1021.

[0039] When the electronic atomizing device is in its first state, the liquid channel 210 is connected to the liquid storage chamber 110, and the air outlet 1021 of the auxiliary airway 102 is disconnected from the air inlet 1022. When the user inhales through the mouthpiece 300, external air enters the main airway 101. The airflow sensor detects the airflow in the main airway 101 and activates the atomizing component 200. At this time, the liquid storage chamber 110 can continuously supply liquid to the atomizing component 200. The atomizing component 200 heats up and atomizes the atomizing medium to form an aerosol. The aerosol is carried by the airflow in the main airway 101 to the mouthpiece 300 for the user to inhale. Meanwhile, since the air outlet 1021 of the auxiliary airway 102 is disconnected from the air inlet 1022, the auxiliary airway 102 is inactive.

[0040] When the electronic atomizing device is in the second state, the liquid channel 210 is disconnected from the liquid storage chamber 110, the air outlet 1021 of the auxiliary air channel 102 is connected to the mouthpiece 300, the air inlet 1022 of the auxiliary air channel 102 is connected to the outside atmosphere, and the air inlet 1022 of the auxiliary air channel 102 is connected to the air outlet 1021. When the user inhales through the mouthpiece 300, the outside atmosphere enters the main air channel 101 and the auxiliary air channel 102 respectively. At this time, since the auxiliary air channel 102 does not need to pass through the atomizing component 200, the path of the auxiliary air channel 102 is relatively short, and the outside atmosphere preferentially flows from the auxiliary air channel 102 to the mouthpiece 300. The airflow sensor in the main air channel 101 is difficult to be triggered, thereby reducing the possibility of false start-up and preventing the atomizing component 200 from dry burning.

[0041] The electronic atomizing device in this embodiment of the application, by additionally setting an auxiliary airway 102 on the basis of the main airway 101, in the second state, the airway outlet 1021 of the auxiliary airway 102 is connected to the mouthpiece 300, the airway inlet 1022 of the auxiliary airway 102 is connected to the external atmosphere, and the airway inlet 1022 of the auxiliary airway 102 is connected to the airway outlet 1021. When the user inhales into the mouthpiece 300, the external atmosphere flows to the mouthpiece 300 through the main airway 101 and the auxiliary airway 102 respectively. The auxiliary airway 102 can share the airflow of the main airway 101, reducing the possibility of the airflow sensor being falsely activated. At the same time, by designing the airflow path of the auxiliary airway 102 to be smaller than the airflow path of the main airway 101, the external gas can mainly flow to the mouthpiece 300 through the auxiliary airway 102, further reducing the possibility of the airflow sensor being falsely activated and avoiding the atomizing component 200 from dry burning.

[0042] In some embodiments, please refer to Figure 3 and Figure 4 In the first state, the nozzle 300 abuts against the liquid storage tank 100 to disconnect the airway inlet 1021 from the airway outlet 1022; in the second state, the nozzle 300 and the liquid storage tank 100 have a first gap 1024, which connects the airway outlet 1021 and the airway inlet 1022 of the auxiliary airway 102.

[0043] In the first state, the nozzle 300 abuts against the liquid storage tank 100, preventing the airway outlet 1021 and airway inlet 1022 of the auxiliary airway 102 from connecting. This prevents external air from entering the auxiliary airway 102 through the airway inlet 1022, ensuring that the auxiliary airway 102 does not affect the airflow of the main airway 101. In the second state, the nozzle 300 and the liquid storage tank 100 have a first gap 1024, which connects the airway outlet 1021 and airway inlet 1022 of the auxiliary airway 102. This allows external air to enter the auxiliary airway 102 through the airway inlet 1022, reducing the possibility of the main airway 101 being activated incorrectly. In general, in this embodiment, the opening and closing of the airway outlet 1021 and airway inlet 1022 of the auxiliary airway 102 are realized by switching between the first state and the second state, so that the state switching of the electronic atomizing device is linked with the opening and closing of the auxiliary airway 102. The switching operation is simple and there is no risk of misoperation.

[0044] In some embodiments, the liquid storage tank 100 and the atomizing component 200 can slide relative to each other along the axial direction to switch between a first state and a second state, and the nozzle 300 is connected to the atomizing component 200 and moves synchronously.

[0045] This can be achieved by driving the liquid storage chamber 100 and the atomizing component 200 to slide relative to each other along the axial direction, thereby switching between the first and second states; alternatively, by driving the liquid storage chamber 100 to slide relative to the atomizing component 200 along the axial direction, thereby switching between the first and second states; or alternatively, by driving the atomizing component 200 to slide relative to the atomizing component 200 along the axial direction, thereby switching between the first and second states.

[0046] It should be noted that, for ease of description, this application refers to the vertical direction from one end of the electronic atomizing device to the other as the axis of the electronic atomizing device, or simply the axis. That is, when the electronic atomizing device is placed stably on a table, the height direction of the electronic atomizing device. In addition, this direction is generally parallel to the axis of the atomizing air passage 1012 of the atomizing component 200.

[0047] In some embodiments, please refer to Figures 1 to 4 The nozzle 300 is connected to the atomizing component 200. The nozzle 300 can be driven to cause the atomizing component 200 to slide axially relative to the liquid storage tank 100 to switch between the first and second states. In this embodiment, the switching between the first and second states of the electronic atomizing device is achieved by the nozzle 300 driving the atomizing component 200 to slide axially. The nozzle 300 is small in size and protrudes from the top outer side of the electronic atomizing device, making it convenient and simple to operate and improving the user experience.

[0048] In some embodiments, please refer to Figure 3 and Figure 4 The liquid storage tank 100 is equipped with a first seal 400. In a first state, the nozzle 300 abuts against the first seal 400. In a second state, a first gap 1024 is formed between the nozzle 300 and the first seal 400. The first seal 400 ensures a sealed connection between the nozzle 300 and the liquid storage tank 100 in the first state, preventing leakage of the atomizing medium from the connection between the nozzle 300 and the liquid storage tank 100.

[0049] Specifically, the first seal 400 is installed at the top opening of the liquid storage chamber 110 corresponding to the liquid storage reservoir 100. The first seal 400 is sleeved on the outside of the atomizing component 200. The first seal 400 is also used to form a seal between the atomizing component 200 and the liquid storage chamber 100 to prevent the atomizing medium from leaking from the connection between the atomizing component 200 and the liquid storage chamber 100.

[0050] In one specific embodiment, please refer to Figure 3 and Figure 4 The nozzle 300 includes a first conical surface 321, and the first seal 400 includes a second conical surface 410. When the liquid storage tank 100 and the atomizing assembly 200 slide towards each other along the axial direction, the first conical surface 321 is sleeved on the second conical surface 410, and the first conical surface 321 and the second conical surface 410 guide the nozzle 300 and the first seal 400 to approach and abut against each other along the axial direction, specifically, the first conical surface 321 abuts against the second conical surface 410.

[0051] In some embodiments, please refer to Figures 2 to 4 The auxiliary airway 102 includes a connecting channel 1023 at least partially formed in the mouthpiece 300. The connecting channel 1023 is connected to the air outlet channel 330 through the airway outlet 1021. In a second state, the connecting channel 1023 is connected to the airway inlet 1022 through a first gap 1024. The connection channel 1023 allows for communication between the first gap 1024 and the air outlet channel 330, which increases the airflow path of the auxiliary airway 102 to a certain extent, ensuring airflow stability within the auxiliary airway 102.

[0052] In some embodiments, please refer to Figure 3 and Figure 4The top of the atomizing component 200 is interference-fitted into the mouthpiece 300; a second gap 1025 is formed between the inner peripheral wall of the mouthpiece 300 and the outer peripheral wall of the atomizing component 200, communicating with the connecting channel 1023; in the second state, the second gap 1025 communicates with the airway inlet 1022 through the first gap 1024. The interference fit ensures a secure connection between the atomizing component 200 and the mouthpiece 300, allowing the mouthpiece 300 to drive the atomizing component 200 to slide axially; the second gap 1025, in addition to the interference fit, also enables communication between the connecting channel 1023 and the airway inlet 1022.

[0053] In some embodiments, please refer to Figure 6 As shown in the figure, the inner peripheral wall of the nozzle 300 is provided with a plurality of circumferentially spaced fitting portions 322, each fitting portion 322 being in interference fit with the outer peripheral wall of the atomizing component 200; a second gap 1025 is formed between two adjacent fitting portions 322. The arrangement of the plurality of fitting portions 322 enables an interference fit connection between the nozzle 300 and the atomizing component 200, preventing damage to the atomizing component 200 during assembly, reducing the precision requirements for the fit between the atomizing component 200 and the nozzle 300, and allowing the nozzle 300 and the atomizing component 200 to be disassembled, replaced, and repaired interchangeably.

[0054] Optionally, the fitting portion 322 is a protrusion protruding from the inner peripheral wall of the nozzle 300, and the second gap 1025 is formed between adjacent protrusions. It can be understood that in other embodiments of this application, the fitting portion 322 may also be a soft rubber pad adhered to the inner peripheral wall of the nozzle 300, or the second gap 1025 may be formed by forming multiple grooves on the inner peripheral wall of the nozzle 300 or the outer peripheral wall of the atomizing assembly 200, which is not a unique limitation here.

[0055] In some embodiments, please refer to Figure 3 and Figure 4 The nozzle 300 and the atomizing component 200 together enclose and form a connecting channel 1023. This design reduces the manufacturing difficulty of the nozzle 300. It is understood that in other embodiments of this application, the connecting channel 1023 may also be directly formed in the nozzle 300, and this is not a unique limitation.

[0056] In one specific embodiment, please refer to Figure 3 and Figure 4The nozzle 300 includes an inner cylinder 310 and an outer cylinder 320; the outer cylinder 320 is sleeved outside the inner cylinder 310, and the top end of the inner cylinder 310 is integrally connected to the top end of the outer cylinder 320. The inner cylinder 310 has an axially penetrating air guide channel 1011, and the air outlet channel 330 is the outer port of the air guide channel 1011; the top end of the atomizing component 200 is inserted into the outer cylinder 320 and communicates with the inner cylinder 310. Specifically, the air guide channel 1011 is connected to the atomizing air passage 1012 of the atomizing component 200, and the inner cylinder 310, the outer cylinder 320, and the atomizing component 200 together form a connecting channel 1023.

[0057] Specifically, the bottom end of the inner cylinder 310 is axially recessed relative to the bottom end of the outer cylinder 320. When the atomizing component 200 is inserted into the outer cylinder 320, the top end of the atomizing component 200 can communicate with the bottom end of the inner cylinder 310. The top end of the atomizing component 200 includes a second sealing element 220. The bottom end of the inner cylinder 310 is inserted into the atomizing component 200, thus forming a sealed connection between the inner cylinder 310 and the atomizing component 200. Specifically, the air guide channel 1011 is connected to the atomizing air passage 1012 of the atomizing component 200. The outer periphery of the second sealing element 220 extends beyond the top end of the atomizing component 200 and abuts against the inner peripheral wall of the outer cylinder 320, thus forming an interference fit between the atomizing component 200 and the outer cylinder 320.

[0058] In some embodiments, the inner cylinder 310 has at least one air outlet 1021, which is located near the air outlet channel 330 and communicates with the connecting channel 1023, thus establishing a connection between the air outlet channel 330 and the connecting channel 1023. The number of air outlets 1021 can be one or more. When there are multiple air outlets 1021, they are arranged sequentially at intervals along the circumference of the inner cylinder 310.

[0059] In some embodiments, please refer to Figure 2 The main airway 101 includes an air guide channel 1011 formed in the mouthpiece 300 and an atomizing airway 1012 formed in the atomizing assembly 200. In this embodiment, by forming an outlet channel 330, an air guide channel 1011, and a connecting channel 1023 in the mouthpiece 300, both the main airway 101 and the auxiliary airway 102 are connected to the mouthpiece 300 when the user inhales, which facilitates gas flow in both the main airway 101 and the auxiliary airway 102. Furthermore, forming the air guide channel 1011 and the connecting channel 1023 in the mouthpiece 300 respectively allows the main airway 101 and the auxiliary airway 102 to be set up independently.

[0060] In one specific embodiment, please refer to Figure 3 and Figure 4The centerline of the air outlet channel 330 coincides with the centerline of the air guide channel 1011, and the centerline of the air guide channel 1011 coincides with the centerline of the nozzle 300. The connecting channel 1023 is formed on the outer periphery of the air guide channel 1011. The above arrangement ensures that the airflow is smooth in the main air passage 101 in the first state, guaranteeing smooth air outlet.

[0061] In some embodiments, please refer to Figure 3 and Figure 4 The liquid storage tank 100 has a receiving cavity 120 communicating with the liquid storage chamber 110, and the bottom end of the suction nozzle 300 is movably disposed in the receiving cavity 120. In the second state, the air outlet 1021 communicates with the receiving cavity 120 through the first gap 1024, and the receiving cavity 120 communicates with the air inlet 1022. The receiving cavity 120 is provided to facilitate the communication between the first gap 1024 and the air inlet 1022, and also to limit and guide the sliding of the suction nozzle 300, preventing the suction nozzle 300 from detaching from the liquid storage tank 100 during the sliding process.

[0062] In this application, the airway inlet 1022 of the auxiliary airway 102 can be formed in different locations, as long as it can communicate with the external atmosphere.

[0063] For example, as an example, the airway inlet 1022 of the auxiliary airway 102 is formed on the outer peripheral wall of the nozzle 300, that is, the airway outlet 1021 and the airway inlet 1022 of the auxiliary airway 102 are both formed on the nozzle 300. This not only makes the path length of the auxiliary airway 102 much smaller than that of the main airway 101, reducing the risk of the airflow sensor being falsely activated, but also makes the forming of the auxiliary airway 102 simple, without having to pass through the liquid storage chamber 100.

[0064] For example, as another example, the air inlet 1022 of the auxiliary airway 102 is formed on the outer peripheral wall of the liquid storage chamber 100. That is, the auxiliary airway 102 passes through both the nozzle 300 and the liquid storage chamber 100, and communicates with the outside atmosphere through the liquid storage chamber 100. In this case, the air inlet 1022 of the auxiliary airway 102 can be formed near the top of the liquid storage chamber 100 to avoid the auxiliary airway 102 occupying the space of the liquid storage chamber 110. At the same time, it also makes the airflow path of the auxiliary airway 102 shorter, which helps to reduce the risk of the airflow sensor being falsely activated.

[0065] For another example, please refer to Figure 4 and Figure 8The air inlet 1022 of the auxiliary airway 102 is formed between the liquid storage tank 100 and the nozzle 300. A gap is provided between the liquid storage tank 100 and the nozzle 300 to allow external air to enter through the gap and communicate with the nozzle 300. In this embodiment, there is no need to make a hole in the outer peripheral wall of the nozzle 300, which makes the surface of the nozzle 300 aesthetically pleasing and also makes the overall path of the auxiliary airway 102 shorter.

[0066] In some embodiments, please refer to Figure 3 , Figures 5 to 7 The liquid storage tank 100 has at least one first snap-fit ​​portion 130, and the suction nozzle 300 has at least one second snap-fit ​​portion 350. The first snap-fit ​​portion 130 and the second snap-fit ​​portion 350 engage in a snap-fit ​​cooperation, that is, the connection between the suction nozzle 300 and the liquid storage tank 100 is formed by the snap-fit ​​cooperation of the first snap-fit ​​portion 130 and the second snap-fit ​​portion 350. The snap-fit ​​cooperation structure is simple, the connection is reliable, and disassembly is simple; it is only necessary to pull the suction nozzle 300 outward along the axial direction, making the operation simple. In other embodiments of this application, the suction nozzle 300 and the liquid storage tank 100 can also be connected by other means, such as a threaded connection.

[0067] In some embodiments, please refer to Figures 4 to 7 The liquid storage tank 100 has at least one axially extending first insertion portion 140, and the nozzle 300 has at least one axially extending second insertion portion 360. The first insertion portion 140 and the second insertion portion 360 are slidably inserted into each other. The first insertion portion 140 and the second insertion portion 360 guide the nozzle 300 into the liquid storage tank 100. That is, before the first locking portion 130 and the second locking portion 350 engage, the first insertion portion 140 and the second insertion portion 360 form a positioning between the nozzle 300 and the liquid storage tank 100, thereby ensuring that the first locking portion 130 and the second locking portion 350 can engage precisely. Furthermore, the first insertion portion 140 and the second insertion portion 360 also guide the sliding of the nozzle 300, ensuring sliding stability, and when the atomizing component 200 is in the second position, the first locking portion 130 and the second locking portion 350 will not disengage.

[0068] Optionally, the first insertion portion 140 includes a slot, and the second insertion portion 360 includes a plug extending downward from the bottom end of the self-suction nozzle 300, the plug being slidably inserted into the slot. In other embodiments, the first insertion portion 140 may include a plug, and the second insertion portion 360 may include a slot; this is not a unique limitation.

[0069] In some embodiments, please refer to Figure 6 and Figure 7The inner peripheral wall of the nozzle 300 is provided with a plurality of circumferentially spaced limiting blocks 340. Each limiting block 340 has a limiting surface, which is used to abut against the axial top surface of the atomizing component 200 to restrict the atomizing component 200 from sliding upward relative to the nozzle 300 in the axial direction, thereby achieving axial positioning of the nozzle 300 and the atomizing component 200.

[0070] The electronic atomizing device also includes a power supply component 500, which supplies power to the atomizing component 200. Specifically, after being powered on, the atomizing component 200 heats and atomizes the atomizing medium stored in the liquid storage chamber 110 to form an aerosol. The aerosol is conducted to the mouthpiece 300 through the hollow atomizing air passage 1012 of the atomizing component 200 and inhaled by the user at the mouthpiece 300.

[0071] In some embodiments, please refer to Figure 3 The electronic atomizing device also includes a main housing 600, which is fitted at the connection between the mouthpiece 300 and the liquid storage chamber 100. The main housing 600 has an assembly port 610 from which the mouthpiece 300 extends. A third gap 1026 exists between the outer peripheral wall of the mouthpiece 300 and the inner peripheral wall of the assembly port 610. The air inlet 1022 communicates with the third gap 1026. The main housing 600 integrates the overall appearance of the electronic atomizing device, making it aesthetically pleasing. In the second state, when the user inhales through the mouthpiece 300, external air enters the gap between the liquid storage chamber 100 and the mouthpiece 300 (i.e., the air inlet 1022) through the third gap 1026, then enters the first gap 1024 through the receiving cavity 120, and then enters the connecting channel 1023 through the second gap 1025, finally flowing to the air outlet channel 330.

[0072] In some embodiments, please refer to Figure 2 The power assembly 500 includes a battery 510 and a battery bracket 520. The main housing 600 is sleeved on the outside of the battery bracket 520 and the electronic atomizing device. The battery bracket 520 forms an air intake channel 1013, which is connected to the air guide channel 1011 through the atomizing air passage 1012. The main housing 600 also has an air inlet 620, which is connected to the air intake channel 1013. The main air passage 101 includes the air guide channel 1011, the atomizing air passage 1012, and the air intake channel 1013.

[0073] For ease of description and understanding, this application uses the example of blocking and opening the lower liquid channel of the atomizing component to disconnect / connect the liquid supply. It is understood that the blocking / disconnection setting can also be set in other parts of the atomizing component, and is not limited to the lower liquid channel; further details will not be provided here.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
