DETAILED DESCRIPTION

[0032] In order to make the technical problems to be solved by the present application, the technical solutions and beneficial effects clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0033] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0035] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an ordered sequence. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0036] As described in the background, the oil core separation technology refers to sealing the lower liquid passage of the atomization assembly during transportation, thereby reducing the leakage of the atomization medium. However, in the prior art, the sealing and opening operation of the lower liquid passage is complex, and the user experience is poor. For example, in some related technologies, the sealing and opening of the lower liquid passage is achieved by pushing the liquid storage bin in the axial direction. Since the liquid storage bin has a large volume, the operation is troublesome, and the user experience is poor. For another example, in some other related technologies, the sealing and opening of the lower liquid passage is achieved by pulling out or inserting the atomization assembly through silica gel. The operation is complex, and the user experience is poor.

[0037] In order to solve the above problems, the electronic atomization device provided by the embodiments of the present application connects the mouthpiece 300 with the atomization assembly 200, and drives the atomization assembly 200 to slide in the axial direction through the mouthpiece 300 to achieve the sealing and opening of the lower liquid passage 210. The mouthpiece 300 has a small volume and protrudes from the top outside of the electronic atomization device, which is convenient and simple to operate, and improves the user experience.

[0038] It should be noted that, for the convenience of description, the sealing and opening of the lower liquid passage 210 of the atomization assembly 200 is taken as an example to realize the disconnection / connection of the liquid supply. It can be understood that the sealing / disconnection can also be provided in other parts of the atomization assembly 200, and is not limited to the lower liquid passage 210.

[0039] Please refer to Figures 1 to 4 , the electronic atomization device provided by the embodiments of the present application will be described.

[0040] The electronic atomization device includes a liquid storage bin 100, an atomization assembly 200 and a mouthpiece 300. The liquid storage bin 100 has a liquid storage cavity 130, and the atomization assembly 200 has a lower liquid passage 210 in communication with the liquid storage cavity 130. The mouthpiece 300 is connected with the atomization assembly 200, and the mouthpiece 300 can be driven to drive the atomization assembly 200 to slide in the axial direction relative to the liquid storage bin 100 and has a first position and a second position. In the state of the first position, the lower liquid passage 210 is in communication with the liquid storage cavity 130, as shown in Figure 3 . In the state of the second position, the lower liquid passage 210 is disconnected from the liquid storage cavity 130, as shown in Figure 4 .

[0041] It should be noted that, for the convenience of description, the vertical direction of the electronic atomization device from one end to the other end is referred to as the axial direction of the electronic atomization device, simply referred to as the axial direction. That is, in the state of placing the electronic atomization device stably on the desktop, the height direction of the electronic atomization device, in addition, the direction is generally parallel to the axial direction of the atomization air channel of the atomization assembly 200.

[0042] The electronic atomization device in the embodiment of the present application connects the suction nozzle 300 with the atomization assembly 200, and the suction nozzle 300 can be driven to drive the atomization assembly 200 to slide along the axial direction relative to the liquid storage compartment 100 and has a first position and a second position. In the state of the atomization assembly 200 in the first position, the lower liquid passage 210 is in communication with the liquid storage cavity 130; in the state of the atomization assembly 200 in the second position, the lower liquid passage 210 is disconnected from the liquid storage cavity 130, that is, the lower liquid passage 210 can be closed and opened by driving the atomization assembly 200 to slide along the axial direction by the suction nozzle 300. When it is necessary to switch the transportation state and the use state of the electronic atomization device, it is only necessary to push and pull the suction nozzle 300 at the top of the electronic atomization device, which is simple and convenient to operate and improves the user experience.

[0043] In some embodiments, please refer to Figures 2 to 4 When the suction nozzle 300 drives the atomization assembly 200 to slide along the axial direction and away from the power assembly 700 to the state of the second position, the lower liquid passage 210 is disconnected from the liquid storage cavity 130; when the suction nozzle 300 drives the atomization assembly 200 to slide along the axial direction and towards the power assembly 700 to the state of the first position, the lower liquid passage 210 is in communication with the liquid storage cavity 130.

[0044] Among them, since the lower liquid passage 210 needs to be in communication with the liquid storage cavity 130 in the normal use state, and the atomization assembly 200 needs to form an electrical connection with the power assembly 700, the design of the first position of the atomization assembly 200 close to the power assembly 700 can ensure the electrical connection stability of the atomization assembly 200. It can be understood that in other embodiments of the present application, under the condition that the atomization assembly 200 and the power assembly 700 can form an electrical connection, it can also be designed that when the suction nozzle 300 drives the atomization assembly 200 to slide along the axial direction and towards the power assembly 700 to the state of the second position, the lower liquid passage 210 is disconnected from the liquid storage cavity 130; when the suction nozzle 300 drives the atomization assembly 200 to slide along the axial direction and away from the power assembly 700 to the state of the first position, the lower liquid passage 210 is in communication with the liquid storage cavity 130.

[0045] In some embodiments, please refer to Figures 2 to 4The atomizing component 200 is provided with a first sealing element 400, which is fixed relative to the liquid storage chamber 100. When the atomizing component 200 is in the first position, the first sealing element 400 avoids the liquid discharge channel 210. When the atomizing component 200 is in the second position, the first sealing element 400 blocks the liquid discharge channel 210.

[0046] In this configuration, the first seal 400 is fixed relative to the liquid storage chamber 100. Therefore, when the atomizing assembly 200 slides axially, the position of the first seal 400 remains unchanged. When the atomizing assembly 200 slides to the first position, the liquid lowering channel 210 of the atomizing assembly 200 can be located above or below the first seal 400, allowing the liquid lowering channel 210 to communicate with the liquid storage chamber 130, thus enabling the electronic atomizing device to function normally. When the atomizing assembly 200 slides to the second position, the liquid lowering channel 210 is blocked by the first seal 400, thereby disconnecting the liquid lowering channel 210 from the liquid storage chamber 100 and ensuring that the atomizing medium does not leak during transportation. Furthermore, the first seal 400 ensures a proper seal for the liquid lowering channel 210.

[0047] As an example, please see Figures 2 to 4 When the atomizing component 200 is in the first position, the first seal 400 is located above the liquid lowering channel 210; when the atomizing component 200 is in the second position, the first seal 400 and the liquid lowering channel 210 are axially aligned and the first seal 400 blocks the liquid lowering channel 210.

[0048] As another example, when the atomizing assembly 200 is in the first position, the first seal 400 is located below the liquid channel 210; when the atomizing assembly 200 is in the second position, the first seal 400 and the liquid channel 210 are axially aligned and the first seal 400 blocks the liquid channel 210.

[0049] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 6 The atomizing component 200 includes multiple circumferentially distributed liquid channels 210. The first sealing member 400 is fixed to the liquid storage chamber 100 and sleeved on the outside of the atomizing component 200. When the atomizing component 200 is in the second position, the first sealing member 400 elastically abuts against the outer peripheral surface of the atomizing component 200 to seal each liquid channel 210 together.

[0050] In some embodiments, please refer to Figure 3 and Figure 4The inner peripheral wall of the first sealing element 400 is provided with two rings of raised ribs 450, which are spaced apart along the axial direction of the first sealing element 400 and are both annular. When the atomizing component 200 is in the second position, the two rings of raised ribs 450 elastically abut against the outer peripheral wall of the atomizing component 200, and each liquid discharge channel 210 is located between the two rings of raised ribs 450, thereby sealing each liquid discharge channel 210.

[0051] Optionally, the first seal 400 is made of silicone, soft rubber, rubber or silicone rubber material.

[0052] In some embodiments, please refer to Figure 2 The liquid storage tank 100 includes a support structure 120 for supporting and guiding the atomizing component 200 to slide axially. The support structure 120 ensures the sliding stability and smoothness of the atomizing component 200 in the liquid storage tank 100, thereby improving the user's operating experience.

[0053] The support structure 120 can extend from the bottom to the top of the liquid storage chamber 130, that is, a cylindrical structure is set in the liquid storage chamber 100 to support and guide the atomizing component 200 to ensure the sliding stability of the atomizing component 200. Alternatively, the support structure 120 can also include at least two support units spaced apart along the axial direction, with multiple support units supporting and guiding the axial sliding of the atomizing component 200, which can reduce manufacturing difficulty and save costs.

[0054] In one specific embodiment, please refer to Figure 2 The liquid storage chamber 100 includes a first support unit 121 and a second support unit 122. The first support unit 121 is located at the bottom of the liquid storage cavity 130, and the second support unit 122 is located at the top opening of the liquid storage cavity 130. The first support unit 121 and the second support unit 122 together support and guide the atomizing component 200. This arrangement not only ensures the support and guidance of the atomizing component 200, but also reduces the manufacturing difficulty of the first support unit 121 and the second support unit 122.

[0055] In some embodiments, the liquid storage tank 100 further includes a tank body 110, with a first support unit 121 integrally formed at the bottom of the tank body 110 and a second support unit 122 integrally formed at the top of the tank body 110. This reduces the processing difficulty of the entire liquid storage tank 100, and also reduces the assembly precision requirements between the support structure 120 and the atomizing component 200, thereby reducing processing costs.

[0056] For details, please refer to Figure 2The chamber body 110 includes a first chamber seat 111 and a second chamber seat 112. The first chamber seat 111 and the second chamber seat 112 are interlocked and sealed together by a third sealing member 600. The first chamber seat 111 and the second chamber seat 112 together enclose a liquid storage chamber 130. A first support unit 121 is integrally formed on the first chamber seat 111, and a second support unit 122 is integrally formed on the second chamber seat 112.

[0057] In some embodiments, please refer to Figures 3 to 5 The first support unit 121 is generally cylindrical. The first support unit 121 extends axially upward from the bottom of the chamber 110. The first support unit 121 is sleeved on the outside of the atomizing component 200 to support and guide the atomizing component 200.

[0058] In some embodiments, please refer to Figures 3 to 5 The first sealing element 400 is installed on the first support unit 121, and the first support unit 121 supports the first sealing element 400 to ensure the sealing fit between the first sealing element 400 and the atomizing component 200.

[0059] In some embodiments, please refer to Figures 3 to 5 The first support unit 121 includes a support portion 1211 protruding from the bottom of the chamber 110 and a flange 1212 protruding from the outer periphery of the top side of the support portion 1211. The flange 1212 and the support portion 1211 form a receiving groove 1213 with an opening facing the atomizing assembly 200. The first sealing member 400 includes a first sealing ring 410 sleeved on the atomizing assembly 200, a second sealing ring 420 surrounding the first sealing ring 410, and a connecting ring 430 connecting the first sealing ring 410 and the second sealing ring 420. The first sealing ring 410, the second sealing ring 420 and the connecting ring 430 together form a mating groove 440 with an opening facing downward. The flange 1212 is inserted into the mating groove 440. The first sealing ring 410 is received in the receiving groove 1213, and two rings of ribs 450 are respectively formed on the inner peripheral wall of the first sealing ring 410.

[0060] In addition, please see Figure 5 The support part 1211 has multiple through grooves 1214 distributed circumferentially, and each through groove 1214 is used to connect the liquid storage chamber 130 and the liquid discharge channel 210.

[0061] In some embodiments, please refer to Figure 2 The second support unit 122 is equipped with a second seal 500, which is used to achieve a sealed connection between the atomizing assembly 200 and the liquid storage tank 100, preventing liquid in the liquid storage chamber 130 from leaking out from the connection between the atomizing assembly 200 and the liquid storage tank 100. The second support unit 122 supports the second seal 500 to ensure a tight seal between the second seal 500 and the atomizing assembly 200.

[0062] In some embodiments, please refer to Figure 9 The second support unit 122 has a first annular groove 1221 and a second annular groove 1222. The first annular groove 1221 communicates with the top opening of the liquid storage chamber 130, and the second annular groove 1222 surrounds the first annular groove 1221. The second sealing member 500 includes a first annular portion 510 and a second annular portion 520. The first annular portion 510 is sleeved on the outside of the atomizing assembly 200, and the second annular portion 520 is connected to the outer peripheral wall of the first annular portion 510 through a connecting portion 530. The second annular portion 520 surrounds the first annular portion 510, the first annular portion 510 is inserted into the first annular groove 1221, and the second annular portion 520 is inserted into the second annular groove 1222.

[0063] In some embodiments, please refer to Figure 2 and Figure 7 The nozzle 300 is fitted onto the top of the atomizing component 200, and the nozzle 300 and the atomizing component 200 are press-fitted. This press-fit connection ensures the strength of the connection between the nozzle 300 and the atomizing component 200, allowing the nozzle 300 to drive the atomizing component 200 to slide axially. It also reduces the assembly difficulty of the nozzle 300 and the atomizing component 200, avoiding modifications to the structure of the atomizing component 200. Understandably, in other embodiments of this application, where structurally permissible, the nozzle 300 and the atomizing component 200 can be connected by snap-fit ​​or adhesive methods; this is not the only possible method.

[0064] For some specific embodiments, please refer to Figure 7 and Figure 8 The inner peripheral wall of the nozzle 300 is provided with a plurality of circumferentially spaced fitting portions 310, each fitting portion 310 being press-fitted against the outer peripheral wall of the atomizing component 200. By having multiple fitting portions 310 press-fitted against the atomizing component 200, damage to the atomizing component 200 during assembly can be avoided, 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.

[0065] Optionally, the fitting portion 310 is a protrusion protruding from the inner peripheral wall of the nozzle 300. The end of the protrusion that guides the atomizing component 200 to be inserted into the nozzle 300 is provided with an inclined guide surface to guide the atomizing component 200 to be inserted quickly. It is understood that in other embodiments of this application, the fitting portion 310 may also be a soft rubber pad pasted on the inner peripheral wall of the nozzle 300, and this is not the only limitation.

[0066] In some embodiments, please refer to Figures 7 to 9The inner peripheral wall of the nozzle 300 is formed with a plurality of circumferentially spaced limiting blocks 320. Each limiting block 320 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 limiting between the nozzle 300 and the atomizing component 200.

[0067] In some embodiments, when the atomizing component 200 is in the first position, the mouthpiece 300 is connected to and detachably connected to the liquid reservoir 100; when the atomizing component 200 is in the second position, the mouthpiece 300 is disconnected from the liquid reservoir 100. This ensures the stability of the connection between the mouthpiece 300 and the liquid reservoir 100 during use, guaranteeing operational stability. It also allows the atomizing component 200 to be switched to the second position by first separating the mouthpiece 300 and the liquid reservoir 100, and then sliding to the second position via the mouthpiece 300. It is understood that in other embodiments of this application, the atomizing component 200 may also be detachably connected to the liquid reservoir 100, while the mouthpiece 300 is not connected to the liquid reservoir 100; this is not a limiting factor.

[0068] In some embodiments, please refer to Figures 6 to 9 The liquid storage tank 100 has at least one first snap-fit ​​portion 114, and the suction nozzle 300 has at least one second snap-fit ​​portion 330. The first snap-fit ​​portion 114 and the second snap-fit ​​portion 330 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 between the first snap-fit ​​portion 114 and the second snap-fit ​​portion 330. The snap-fit ​​cooperation structure is simple, the connection is reliable, and disassembly is simple; it only requires pulling 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.

[0069] In some embodiments, please refer to Figure 2 and Figure 9 The liquid storage chamber 100 has a receiving cavity 113 communicating with the top opening of the liquid storage chamber 130. The receiving cavity 113 penetrates the top sidewall of the liquid storage chamber 100, and the inner diameter of the receiving cavity 113 is larger than the inner diameter of the top opening of the liquid storage chamber 130. A first engaging portion 114 is formed on the inner peripheral wall of the receiving cavity 113, and a second engaging portion 330 is formed on the outer peripheral wall of the nozzle 300. The bottom of the nozzle 300 is inserted into the receiving cavity 113 and can slide axially within the receiving cavity 113. When the atomizing assembly 200 is in the first position, the first engaging portion 114 and the second engaging portion 330 engage; when the atomizing assembly 200 is in the second position, the first engaging portion 114 and the second engaging portion 330 disengage.

[0070] As an example, please see Figure 9The first engaging portion 114 includes a locking block formed on the inner peripheral wall of the receiving cavity 113. The locking block has a first abutting surface 1141 facing the power assembly 700 and a first guiding surface 1142 facing away from the power assembly 700. The second engaging portion 330 includes a hook formed on the outer peripheral wall of the suction nozzle 300. The hook has a second abutting surface 331 facing away from the power assembly 700 and a second guiding surface 332 facing the power assembly 700. The first abutting surface 1141 and the second abutting surface 331 are both perpendicular to the axial direction, and the first guiding surface 1142 and the second guiding surface 332 are both inclined at an acute angle relative to the axial direction. When the bottom end of the nozzle 300 is inserted into the receiving cavity 113 and the nozzle 300 is pushed downward along the axial direction, the second guide surface 332 abuts against and overcomes the resistance of the locking block from its state of being in contact with the first guide surface 1142, until the hook slides from the first guide surface 1142 of the locking block into the first contact surface 1141 of the locking block. The first contact surface 1141 abuts against the second contact surface 331, thereby restricting the nozzle 300 from sliding away from the power supply assembly 700. At the same time, the bottom end surface of the nozzle 300 abuts against the bottom side surface of the receiving cavity 113, restricting the nozzle 300 from sliding further towards the power supply assembly 700, thereby achieving axial positioning of the nozzle 300 to stably hold the atomizing assembly 200 in the first position. When the nozzle 300 is pulled outward along the axial direction, the hook overcomes its own elasticity to disengage from the locking block, thereby allowing the atomizing assembly 200 to slide from the first position to the second position.

[0071] In addition, it should be noted that the electronic atomizing device is also fitted with a main housing 800, which extends at least partially to the top opening of the accommodating cavity 113 to block the hook and prevent the mouthpiece 300 from detaching from the entire electronic atomizing device.

[0072] In some embodiments, the number of first latching portions 114 may be one, two, three or more, and correspondingly, the number of second latching portions 330 may also be one, two, three or more.

[0073] In some embodiments, please refer to Figure 8 and Figure 10The liquid storage tank 100 has at least one axially extending first insertion portion 115, and the nozzle 300 has at least one axially extending second insertion portion 340. The first insertion portion 115 and the second insertion portion 340 are slidably inserted into each other. The first insertion portion 115 and the second insertion portion 340 guide the nozzle 300 into the liquid storage tank 100. That is, before the first locking portion 114 and the second locking portion 330 engage, the first insertion portion 115 and the second insertion portion 340 form a positioning between the nozzle 300 and the liquid storage tank 100, thereby ensuring that the first locking portion 114 and the second locking portion 330 can engage precisely. Furthermore, the first insertion portion 115 and the second insertion portion 340 also guide the sliding of the nozzle 300, ensuring sliding stability. When the atomizing component 200 is in the second position, the first locking portion 114 and the second locking portion 330 will not disengage.

[0074] Optionally, the first insertion portion 115 includes a slot, and the second insertion portion 340 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 115 may include a plug, and the second insertion portion 340 may include a slot; this is not a unique limitation.

[0075] Optionally, there are multiple first plug-in portions 115, and each first plug-in portion 115 is distributed sequentially at intervals along the circumference of the suction nozzle 300; there are also multiple second plug-in portions 340, and each second plug-in portion 340 is distributed sequentially at intervals along the circumference of the suction nozzle 300. Each first plug-in portion 115 and each second plug-in portion 340 are plugged in one-to-one to ensure the plugging guidance stability of the suction nozzle 300.

[0076] In some embodiments, please refer to Figure 8 The nozzle 300 has a hollow groove 350 that extends through the bottom end of the nozzle 300. The hollow groove 350 is located between the outer and inner peripheral walls of the nozzle 300, and each second engaging portion 330 is provided corresponding to the hollow groove 350. Specifically, one hollow groove 350 can be provided for each second engaging portion 330, or one hollow groove 350 can be provided for every two second engaging portions 330, or an annular hollow groove 350 can be provided for each second engaging portion 330. The hollow groove 350 can improve the elasticity of the outer peripheral wall of the second engaging portion 330, thereby enabling the second engaging portion 330 to smoothly engage with the first engaging portion 114.

[0077] In some embodiments, please refer to Figure 9The inner peripheral wall of the nozzle 300 has a first conical portion 360 near its bottom end, and the outer peripheral wall of the second seal 500 has a second conical portion 540. When the atomizing assembly 200 is in the first position, the first conical portion 360 is interference-fitted onto the second conical portion 540, thereby forming a sealed connection between the nozzle 300 and the liquid storage tank 100 to prevent leakage of the atomizing medium.

[0078] The electronic atomizing device also includes a power supply component 700, which supplies power to the atomizing component 200. After being powered on, the atomizing component 200 heats and atomizes the atomizing medium stored in the liquid storage chamber 130 to form an aerosol. The aerosol is conducted to the mouthpiece 300 through the hollow atomizing channel of the atomizing component 200 and is inhaled by the user at the mouthpiece 300.

[0079] Please see Figure 1 and Figure 2 The electronic atomizing device also includes a main housing 800, which is fitted outside the electronic atomizing device and the power supply assembly 700. The mouthpiece 300 extends from the top opening of the main housing 800 for the user to inhale.

[0080] For ease of description and understanding, this application uses the example of blocking and opening the liquid supply channel 210 of the atomizing assembly 200 to disconnect / connect the liquid supply as an example to illustrate the embodiments of the present invention. It is understood that the blocking / disconnection setting can also be set in other parts of the atomizing assembly 200, and is not limited to the liquid supply channel 210, which will not be described in detail in this application.

[0081] 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.
