Description

Technical Field

[0001] This application relates to the field of electronic atomization, and more particularly to an electronic atomization device and its atomizing cartridge and atomizing host. Background Technology

[0002] Traditional electronic atomizing devices on the market typically have their atomizing components fixed inside the atomizing cartridge along with the liquid reservoir, forming a detachable structure with the atomizing main unit. Most of these are disposable consumables, and after use, a new atomizing cartridge is directly replaced and assembled onto a reusable atomizing main unit.

[0003] Currently, there is a known electronic atomizing device with a separate structure for the liquid reservoir. The atomizing device is fixedly mounted on the upper part of the atomizing main unit, while the liquid reservoir is located inside the atomizing cartridge. The atomizing cartridge with the liquid reservoir inside can be directly fitted onto the atomizing main unit. The atomizing cartridge and the atomizing main unit are detachable and reassembleable. The atomizing liquid in the liquid reservoir is supplied to the atomizing device through a liquid guiding channel. When the atomizing liquid is used up, it can be replaced with a new liquid reservoir. The atomizing components do not need to be replaced frequently and can be used for a long time. This structure provides a cheaper disposable atomizing cartridge for the electronic atomizing device as a whole.

[0004] However, the drawbacks of this type of detachable and assembleable electronic atomizing device between the atomizing cartridge and the atomizing unit are that after the atomizing cartridge is placed on the atomizing unit, the atomizing liquid will be transported to the atomizing component located on the top of the atomizing unit through the liquid guide channel. If the atomizing liquid is not atomized in time, it will remain on the atomizing device, which can easily cause oil leakage and damage to the atomizing device, shortening the life of the atomizing component. Furthermore, once the atomizing liquid that has been covered on the atomizing component for a long time is atomized, there may be a problem with the atomized liquid not being clean and hygienic enough, affecting the user's experience and health. Summary of the Invention

The liquid guiding assembly is located axially closer to the outlet of the liquid storage cup within the sleeve assembly. The outer rotating part passes through the first slot of the atomizing host. A part of the outer transmission part is exposed outside the shell of the atomizing host.

[0045] The atomizing host proposed in this application includes all the technical solutions described in the above-mentioned electronic atomizing device.

[0046] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0047] The electronic atomizing device includes an atomizing cartridge, an atomizing main unit, and a liquid control assembly. The atomizing cartridge includes a sleeve assembly housed within a cavity formed by a liquid reservoir. One end of the sleeve assembly is connected to the mouthpiece. The sleeve assembly has a liquid inlet and is axially movable relative to the liquid reservoir. A liquid guiding assembly is located inside the sleeve assembly and corresponds to the liquid inlet. The atomizing main unit includes a liquid control assembly consisting of an inner rotating component and an outer rotating component that mesh with each other. The inner rotating component is located at the bottom of the sleeve assembly, and the liquid guiding assembly is positioned axially closer to the liquid reservoir outlet within the sleeve assembly. The outer rotating component passes through the atomizing main unit. In the first slot, a portion of the external transmission component is exposed outside the housing wall of the atomizing host. The liquid control component can move relative to the liquid inlet hole to press or loosen the liquid guiding component. When the liquid guiding component 108 is pressed, the amount of liquid flowing into the liquid guiding component decreases. When the liquid guiding component is loosened, the amount of liquid flowing into the liquid guiding component increases, thereby controlling the amount of atomizing liquid flowing into the liquid guiding component. In this way, only the required amount of liquid needs to be provided to the liquid guiding component, reducing the amount of atomizing liquid remaining in the liquid guiding component, shortening the residence time of the atomizing liquid on the liquid guiding component, reducing leakage, and extending the service life of the liquid guiding component, atomizing bullet, and electronic atomizing device.

[0062] The realization of the objectives, functional features and advantages of the embodiments of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0063] This application provides an electronic atomizing device for causing relative displacement between the liquid control component and the liquid inlet, pressing or releasing the liquid guiding component, controlling the amount of atomizing liquid entering the device, shortening the residence time of the atomizing liquid on the liquid guiding component, reducing the amount of atomizing liquid remaining, reducing leakage, and extending the service life of the liquid guiding component, atomizing bullet, and electronic atomizing device.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0065] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0066] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0067] In this embodiment of the application, please first refer to... Figure 6 , Figures 9 to 11 The technical solutions involved in the electronic atomization device will be described in the following sections. Figures 1 to 5 , Figures 7 to 8 The technical solutions involved in the electronic atomization device are described in detail.

[0068] In the embodiments of this application, reference is made to Figure 6 , Figures 9 to 11 The electronic atomizing device includes an atomizing cartridge 1, an atomizing main unit 2, and a liquid control component 4.

[0069] The upper cover housing 101 has a first slot 1011 provided on the lower part of the housing wall;

[0070] Mouthpiece 102;

[0071] The liquid storage cup 103 is arranged in a ring shape along the axial direction inside the upper cover housing 101. A cavity is formed in the center of the liquid storage cup 103. The liquid storage cup 103 is provided with a liquid storage cup outlet 104, and there is at least one liquid storage cup outlet 104.

[0072] A sleeve assembly 105 is disposed in the cavity, with one end connected to the suction nozzle 102. The sleeve assembly 105 has a liquid inlet 106 and is axially movable relative to the liquid storage cup 103. The outer peripheral wall of the sleeve assembly 105 is in close contact with the liquid storage cup outlet 104.

[0073] The liquid guiding component 108 is disposed inside the sleeve assembly 105 and is correspondingly disposed to the liquid inlet 106;

[0074] The atomizing device 2 includes an atomizing component 202, which includes:

[0075] The atomizing coil 201 is located at the upper end of the atomizing unit 2; and

[0076] The liquid control assembly 4 consists of an inner rotating part 401 and an outer rotating part 402 that mesh with each other. The inner rotating part 401 is located at the bottom of the sleeve assembly 105. The liquid guiding assembly 108 is located axially closer to the liquid storage cup outlet 104 in the sleeve assembly 105. The outer rotating part passes through the first slot 201 of the atomizing host 2. A part of the outer transmission part 402 is exposed outside the shell wall of the atomizing host 2. The liquid control assembly 4 can move relative to the liquid inlet 106 so that the liquid guiding assembly 108 is pressed or released, changing the amount of atomized liquid 109 flowing into the liquid guiding assembly 108.

[0077] Specifically, a first screw 403 is axially upwardly positioned at the center of the inner rotating component 401, and the sleeve assembly 105 ( Figure 10 and Figure 11 The inner wall of the airway inner sleeve 1051 (not marked) is provided with a first thread 404. The first screw 403 and the first thread 404 mesh with each other so that when the inner rotating part 401 rotates, it drives the first screw 403 to move up and down along the axial direction, thereby pressing or loosening the liquid guiding assembly 108.

[0078] In addition, a second screw 405 is provided axially at the center of the outer rotating part 402, and at least one protrusion 114 extending toward the center is provided on the inner wall of the upper cover housing 101. Each protrusion 114 is provided with a second slot (not shown), and there is at least one second slot. The second screw 405 is inserted into the second slot, and the protrusion 114 is located axially below the liquid storage cup 103.

[0079] It should be noted that the second screw 405 may have threads only at the position where it contacts the outer rotating member 402. In this case, the outer rotating member 402 can rotate circumferentially along the second screw 405, while the second screw 405 is fixedly inserted into the second slot. Alternatively, the second screw 405 may also have threads on the inner wall of the second slot, allowing the outer rotating member 402 and the second screw 405 to rotate circumferentially together. In this case, the second screw 405 also rotates circumferentially within the second slot simultaneously. The specific location of the threads on the second screw 405 is not limited here.

[0080] Specifically, please see Figures 1 to 9When the inner rotating member 401 rotates, it drives the first screw 403 to move upward along the axial direction. The portion of the inner rotating member 401 along the circumferential section can push the liquid guiding assembly 108 axially toward the nozzle 102. The liquid guiding assembly 108 is compressed by the external force of the push, and the pores inside the liquid guiding assembly 108 become smaller. Since the liquid guiding assembly 108 and the liquid inlet 106 are correspondingly arranged, the amount of atomized liquid 109 flowing into the liquid guiding assembly 108 through the liquid inlet 106 decreases accordingly. When the inner rotating member 401 rotates in the opposite direction, it drives the first screw 403 to move upward along the axial direction. When the first screw 403 moves downward along the axial direction, the part of the inner rotating member 401 along the circumferential section moves away from the inlet nozzle 102 along the axial direction. The part of the inner rotating member 401 along the circumferential section can relax the axial pressure on the liquid guiding assembly 108. The liquid guiding assembly 108 is released due to the reduction of the external force of the pressure, the pores inside the liquid guiding assembly 108 become larger, and the liquid guiding assembly 108 is still correspondingly set with the liquid inlet hole 106. As a result, the amount of atomized liquid 109 flowing into the liquid guiding assembly 108 from the liquid inlet hole 106 increases.

[0081] Furthermore, the rotation of the inner rotating member 401 is driven by the rotation of the outer rotating member 402. Since the outer rotating member 402 and the inner rotating member 401 are meshed with each other, when an external force is applied to the outer rotating member 402 in a circumferential rotational direction, the inner rotating member 401 will rotate accordingly. It should be noted that the rotation direction of the inner rotating member 401 is opposite to the rotation direction of the outer rotating member 402.

[0082] Furthermore, since the outer rotating component 402 passes through the first slot 1011 of the atomizing host 2, and a portion of the outer transmission component 402 is exposed outside the shell wall of the atomizing host 2, the first slot 1011 serves to limit the vertical movement of the outer transmission component 402. Therefore, the outer transmission component 402 will not move vertically in the axial direction due to its meshing rotation with the inner rotating component 401. In this embodiment, only the inner rotating component 401 moves vertically in the axial direction due to its meshing rotation with the outer transmission component 402, thereby pressing or sending the liquid guiding assembly 108. Due to the action and reaction forces, the outer rotating component 402 will also experience axial vertical movement during rotation. Therefore, to ensure that the outer rotating component 402 does not experience axial vertical movement, the inner rotating component 401, or the inner rotating component 401 and the first screw 403 as a whole, or both the inner rotating component 401 and the outer rotating component 402 can be made of materials with relatively high sliding coefficients. Furthermore, materials with higher hardness can be used to make the inner rotating component 401 and the outer rotating component 402. Additionally, the degree of meshing between the inner rotating component 401 and the outer rotating component 402 can be adjusted during the manufacturing process. To achieve greater precision, the inner rotating component 401 can not only drive the first screw 403 to move up and down axially during rotation, but also, due to the large sliding coefficient between the two, the frictional force generated in the axial direction between the inner rotating component 401 and the outer rotating component 402 is small. Thus, although the first screw 403 can move up and down axially during the rotation of the inner rotating component 401, the meshing part between the outer rotating component 402 and the inner rotating component 401 will produce a certain amount of sliding in the axial direction. Therefore, the outer rotating component 402 can achieve the technical effect of rotating but not moving up and down axially.

[0083] With this setup, the inner rotating component 401, located inside the electronic atomizing device, can rotate from a minimum of 0° to a maximum of 180° due to the rotation of the outer rotating component 402. This ensures that the inner rotating component 401 can compress or relax the oil guiding component 108 to the maximum extent in the axial direction, thereby improving the practicality of the oil control function of the electronic atomizing device.

[0084] Furthermore, in the embodiments of this application, the inner rotating component can be an internal gear or an internal pressure rod, and the outer rotating component can be an external gear or an external lever; the specific type is not limited here. For example, if the inner rotating component is an internal gear, the outer rotating component can be an external gear meshing with the internal gear; or, if the inner rotating component is an internal gear, the outer rotating component can be an external lever connected to the internal gear; or, if the inner rotating component is an internal pressure rod, the outer rotating component can be an external gear.

[0085] It should be noted that there can be one, two, or more protrusions on the inner wall of the top cover housing; the specific number is not limited here. Each protrusion can have a second slot, so when the two atomizing main units and the atomizing cartridge 1 are detachable and assembleable, they do not need to be limited to a single fixed position for insertion. Instead, they can be assembled at multiple different positions in the circumferential direction, improving the flexibility and practicality of the electronic atomizing device.

[0086] Furthermore, the first slot can be a narrow slit or a square hole; no specific limitation is made here. The second slot can be a round hole or a polygon, and its shape varies depending on the shape of the second screw; no specific limitation is made here. Similarly, the shape of the first screw matches the internal shape of the sleeve assembly; no specific limitation is made here.

[0087] In this embodiment, through such a structural setup and working principle, the liquid control component 4 can press or release the liquid guiding component 108 by achieving relative displacement between itself and the liquid inlet 106. When the liquid guiding component 108 is pressed, the amount of liquid flowing into the liquid guiding component 108 decreases; when the liquid guiding component 108 is released, the amount of liquid flowing into the liquid guiding component 108 increases. This controls the amount of atomizing liquid 109 flowing into the liquid guiding component 108. In this way, only the required amount of liquid needs to be provided to the liquid guiding component 108, reducing the amount of atomizing liquid 109 remaining in the liquid guiding component 108, shortening the residence time of atomizing liquid 109 on the liquid guiding component 108, reducing leakage, and extending the service life of the liquid guiding component 108, the atomizing bullet 1, and the electronic atomizing device 3.

[0088] The embodiments of controlling the inflow of atomizing liquid 109 into the liquid guiding component 108 in this application have been described in detail above. The embodiments of opening and closing the liquid storage cup outlet 104 in this application will be described below.

[0089] In the embodiments of this application, reference is made to Figure 1 The atomizing bullet 1 of the electronic atomizing device 3 also includes a liquid hole baffle 107. The liquid hole baffle 107 is disposed on the inner wall of the upper cover housing 101 and is located axially below the bottom of the liquid storage cup 103. The liquid hole baffle 107 is in close contact with the outer peripheral wall of the sleeve assembly 105. The liquid hole baffle 107 opens or covers the liquid inlet hole 106 by relative displacement between it and the liquid inlet hole 106 in the axial direction.

[0090] Please see Figure 2 and Figure 3 , Figure 2 This is a cross-sectional schematic diagram of an electronic atomizing device in the combined state of the atomizing bullets in an embodiment of this application. Figure 3This is a perspective cross-sectional view of the electronic atomizing device in the combined state of the atomizing cartridge in this embodiment of the application. Specifically, in this embodiment of the application, the atomizing cartridge 1 has a liquid storage cup 103 formed by the upper cover shell 101, the sleeve assembly 105, and the liquid hole baffle 107. When the sleeve assembly 105 is pushed by an external force, it can move axially relative to the liquid storage cup 103 towards the suction nozzle 102 (see...). Figure 2 and Figure 3 (The arrow indicates the direction of movement of the sleeve assembly 105). As a result, the liquid inlet 106 provided on the sleeve assembly 105 undergoes relative displacement in the axial direction between itself and the liquid hole baffle 107 provided below the bottom of the liquid storage cup 103. The liquid inlet 106 moves toward the nozzle 102 until it reaches a position where it does not contact the liquid hole baffle 107. At this time, the liquid inlet 106 connects with the outlet of the liquid storage cup 103, that is, the liquid inlet 105 is opened, the oil passage is connected, and the atomizing liquid 109 flows through the liquid inlet 106 to the liquid guide assembly 108.

[0091] When the sleeve assembly 105 is subjected to a tensile force opposite to the external force, it can move axially relative to the reservoir cup 103 away from the suction nozzle 102 (see...). Figure 4 and Figure 5 (The arrow indicates the direction of movement of the sleeve assembly 105). As a result, the liquid inlet 106 is relatively displaced axially between itself and the liquid outlet baffle 107. The liquid inlet 106 moves away from the nozzle 102 until it reaches a position where it is in close contact with the liquid outlet baffle 106. At this time, the liquid outlet baffle 106 covers the liquid inlet 105, and the outer peripheral wall of the sleeve assembly 105 is in close contact with the liquid storage cup outlet 104. At this time, the liquid inlet 106 and the liquid storage cup outlet 104 are not connected, and the liquid storage cup outlet 104 is also blocked by the outer peripheral wall of the sleeve assembly 105. The oil passage is not open, blocking the path of the atomizing liquid 109 to the liquid guiding assembly 108.

[0092] In this embodiment of the application, at least one liquid hole baffle 107 is provided on the inner peripheral wall of the upper cover housing 101. The number of liquid hole baffles 107 can be one, two or more, or they can be provided on the inner peripheral wall of the upper cover housing 101 along the circumferential direction around the sleeve assembly 105. The specific details are not limited here.

[0093] Furthermore, the liquid orifice baffle 107 has a downwardly bent edge near the outer edge of the sleeve assembly 105, and the bend angle of the bend is 0-180°. In order to ensure that the liquid orifice baffle 107 can be in close contact with the sleeve assembly 105 and the liquid inlet 106, the bend angle of the bend is preferably 90°.

[0094] Furthermore, the material of the liquid hole baffle 107 can be metal or plastic, and no specific limitation is made here.

[0095] also, Figure 1 The container also has an air inlet 113, which is used to balance the external atmospheric pressure, allowing air to enter the liquid storage cup 103 and balance the atmospheric pressure in the liquid storage cup 103 with the external atmospheric pressure, preventing the atomized liquid from not flowing out due to the formation of a vacuum above the liquid surface in the liquid storage cup 103.

[0096] In this embodiment, since the sleeve assembly 105 can move axially relative to the liquid storage cup 103, when the inlet hole 106 on the sleeve assembly 105 moves upward relative to the liquid storage cup 103, it also moves upward relative to the liquid hole baffle 107 until it is misaligned with the liquid hole baffle 107. At this point, the inlet hole 106 is opened and connects with the liquid storage cup outlet 104, thus opening the oil passage and allowing the atomizing liquid 109 to flow into the guide liquid assembly 108. Conversely, when the inlet hole 106 on the sleeve assembly 105 moves downward relative to the liquid storage cup 103, it also moves downward relative to the liquid hole baffle 107 until the liquid hole baffle 107 completely blocks the inlet hole 106, and the outer peripheral wall of the sleeve assembly 105 is tightly closed with the liquid storage cup outlet 104. When there is no tight contact, the inlet hole 106 is not connected to the outlet 104 of the liquid storage cup. The outer peripheral wall of the sleeve assembly 105 of the outlet 104 of the liquid storage cup is blocked, the oil circuit is not connected, and the path of the atomizing liquid 109 to the liquid guiding assembly 108 is blocked. This allows control over the opening and closing of the path of the atomizing bullet 1 to the liquid guiding assembly 108 of the atomizing liquid 109. The inlet hole 106 is only connected to the liquid storage cup 103 when the user needs to inhale. This greatly shortens the residence time of the atomizing liquid 109 in the liquid guiding assembly 108, reduces the amount of atomizing liquid 109 remaining in the liquid guiding assembly 108, reduces leakage of the atomizing bullet 1, and extends the service life of the liquid guiding assembly 108, the atomizing bullet 1, and the electronic atomizing device 3.

[0097] In this embodiment, the atomizing cartridge 1 can be a smoke cartridge, an aromatherapy atomizing cartridge for relieving fatigue, or a medical liquid atomizing cartridge for treating diseases of the throat, trachea, and lungs; the specific type is not limited here. Correspondingly, the electronic atomizing device 3 can be an electronic cigarette, an aromatherapy atomizing device for relieving fatigue, or a medical atomizing device for treating diseases of the throat, trachea, and lungs; the specific type is not limited here.

[0098] Further, please refer to Figure 6 , Figure 6 This is a partial exploded view of a fogging bomb in an embodiment of this application.

[0099] The liquid inlet 106 includes an inner liquid inlet 1060 and an outer liquid inlet 1061;

[0100] The sleeve assembly 105 includes:

[0101] The airway inner sleeve 1051 is connected at one end to the mouthpiece 102;

[0102] A limiting sleeve 1052 is fixedly sleeved on the outer wall of the inner sleeve 1051 of the airway, and an inner liquid inlet hole 1060 is opened on the surface of the limiting sleeve 1052.

[0103] The outer sleeve 1053 is slidably sleeved on the outer wall of the limiting sleeve 1052 and is axially connected to the limiting sleeve 1052. The surface of the outer sleeve 1053 is provided with an external liquid inlet hole 1061 so that the external liquid inlet hole 1061 and the internal liquid inlet hole 1060 are connected when they coincide or staggered when they do not coincide.

[0104] Furthermore, a first limiting member (not shown in the figure) is provided on the inner wall of the limiting sleeve 1052. When the limiting sleeve 1052 and the other end of the airway inner sleeve 1051 abut against each other, the first limiting member can prevent the airway inner sleeve 1052 from continuing to move relative to the limiting sleeve 1052 in the axial direction away from the nozzle 102.

[0105] Specifically, the inner diameter of the outer sleeve 1053 is larger than the inner diameter of the limiting sleeve 1052. A second limiting member (not shown) is provided on the inner wall of the outer sleeve 1053. The outer sleeve 1053 inserts the limiting sleeve 1052. When the second limiting member of the outer sleeve 1053 abuts against the limiting sleeve 1052, the outer liquid inlet 1061 and the inner liquid inlet 1060 coincide and connect. Then, when the second limiting member of the outer sleeve 1053 pushes the abutting part of the limiting sleeve 1052 by external force, the outer sleeve 1053, the limiting sleeve 1052, and the inner sleeve 1051 of the airway continue to move axially together relative to the liquid storage cup 103 and toward the suction nozzle 102 until the liquid inlet 106 and the liquid storage cup outlet 104 are connected. At this time, the sealing ring 110 located near the nozzle 102 and on the outer peripheral wall of the sleeve assembly 105 not only prevents the atomizing liquid 109 from leaking out, but also serves as a limit, restricting the sleeve assembly 105 from moving forward after reaching the lower end of the nozzle 102, thus preventing the sleeve assembly 105 from passing through the nozzle 102 and protruding out. When the second limiting member of the outer sleeve 1053 is subjected to a pulling force opposite to the pushing force, the outer sleeve 1053, the limiting sleeve 1052, and the inner sleeve 1051 of the air passage move together axially relative to the liquid storage cup 103 in a direction away from the nozzle 102. When the second limiting member of the outer sleeve 1053 and the limiting sleeve 1052 separate axially, the outer liquid inlet 1061 and the inner liquid inlet 1062 do not coincide and are misaligned. Of course, at this time, the outer liquid inlet 1061... Both the inner liquid inlet 1062 and the liquid storage cup outlet 104 are offset. The inner liquid inlet 1062 is pulled away from the suction nozzle 102 by an external force to a position where it is in close contact with the liquid inlet baffle 107. The liquid inlet baffle 107 blocks the inner liquid inlet 1062, while the outer liquid inlet 1061 is pulled away from the suction nozzle 102 by an external force to a position below the inner liquid inlet 1062 (not shown). It may or may not be in close contact with the liquid inlet baffle 107.

[0106] It should be noted that the number of outlets 104 of the liquid storage cup is the same as the number of external liquid inlets 1061 and internal liquid inlets 1061.

[0107] It should be noted that the lower end of the sleeve assembly 105 is also provided with a chamfer 111. When the liquid hole baffle 107 covers the liquid inlet hole 112, the upper end of the liquid hole baffle 107 that is in close contact with the sleeve assembly 105 is engaged with the chamfer 111. This allows the sleeve assembly 105 to stop moving relative to the nozzle 102 when it is subjected to a pulling force in the axial direction opposite to that of the nozzle 102, ensuring that the entire sleeve assembly 105 will not be pulled out from the bottom of the atomizing bullet.

[0108] As can be seen from the above, in the specific structure of the sleeve assembly 105 in this embodiment, when the bottom of the atomizing bullet 1 is subjected to an upward thrust, the outer liquid inlet 1061 and the inner liquid inlet 1060 can overlap, and then rise to a position offset from the liquid hole baffle 107, and connect with the liquid storage cup outlet 104; while when the bottom of the atomizing bullet 1 is subjected to a downward pull, the entire sleeve assembly 105 descends to a position in close contact with the liquid hole baffle 107, and the outer peripheral wall of the sleeve assembly 105 is in close contact with the liquid storage cup outlet 104, and the liquid storage cup outlet 104 is closed, thereby controlling atomization. The cartridge opens and closes the path of the atomizing liquid to the liquid guiding component 108. The user only needs to combine the atomizing cartridge 1 and the atomizing host 2 (which will be described in detail later) when inhaling, so that the liquid inlet 106 is connected to the liquid storage cup 103. This not only reduces the time that the atomizing liquid 109 covers the liquid guiding component 108 and the atomizing core 201 (which will be described in detail later), but also extends the service life of the liquid guiding component 108 and the atomizing core 201. Furthermore, it reduces leakage from the liquid storage cup 103 and improves the performance of the product.

[0109] Furthermore, in this embodiment, the liquid guiding component 108 is disposed inside the outer sleeve 1053, and the upper end of the atomizing core 201 is set as a plane. This structure is beneficial for the use scenario when the atomizing core 201 is an ultrasonic atomizing core, and facilitates the generation of vaporized smoke by direct and repeated collisions with the liquid guiding component 108.

[0110] Furthermore, in this embodiment, a portion of the fluid guiding component 108 extends radially from the bottom of the sleeve assembly 105 to the lower inner wall of the sleeve assembly 105.

[0111] Furthermore, a portion of the fluid guiding assembly 108 extends radially from the bottom of the outer sleeve 1053 to contact the inner wall of the lower end of the outer sleeve 1053.

[0112] In this embodiment, the liquid guiding component 108 can be arranged in a concave structure, with the central part recessed and abutting against the bottom of the outer sleeve 1053, and the remaining part higher than the central part and extending radially in a ring to the lower inner wall of the outer sleeve 1053, and contacting the lower inner wall. That is to say, the liquid guiding component 108 located at the bottom of the outer sleeve 1053 and the liquid guiding component extending to the lower inner wall of the outer sleeve 1053 are both concentric circle structures.

[0113] Specifically, the liquid guiding assembly 108 includes at least three layers from top to bottom (not shown in the layer diagram). The topmost first layer is used to fix the movement of the second layer located in the middle layer. The second layer is used for guiding liquid. The bottommost third layer is used to protect the second layer so that the second layer remains intact during use. The third layer can also play an auxiliary role in guiding liquid. In addition, the first layer can also be used to press the third layer into contact with the atomizing core 201.

[0114] In this embodiment, the first layer can be made of metal, forming a metal mesh layer with a certain degree of elasticity, or a metal pressure mesh. Preferably, the mesh density is such that it does not impede the flow of the atomized liquid. The first layer can also be made of plastic with a certain degree of elasticity, forming a plastic pore layer with many small holes; the specific details are not limited here. The second layer can be made of cotton-based liquid-guiding cotton, or a liquid-guiding cotton interlayer made of cotton or a blend of cotton and aramid fibers to facilitate liquid guidance. The third layer is made of a flexible and wear-resistant material. Even if the atomizing core 201 and the outer tube 1053 on the atomizing host 2 are frequently rubbed or frequently impacted by external forces, it can remain intact and protect the second layer from damage. Furthermore, it can assist in liquid guidance. Therefore, the third layer can be made of aramid or ultra-high molecular weight polyethylene fiber.

[0115] Based on the structure of the liquid guiding assembly 108 with the above three layers, when the liquid inlet 106 and the liquid storage cup outlet 104 are connected, the liquid guiding assembly 108 is in the position corresponding to the liquid inlet 106. The atomized liquid 109 flows into the liquid guiding assembly 108. The second layer of the liquid guiding assembly and the third layer of the liquid guiding assembly draw the atomized liquid 109 into the liquid guiding assembly 108 at the bottom recess of the outer sleeve 1053. Thus, when the atomizing bullet 1 is pushed upward and combined with the atomizing host 2, the atomizing core 201 at the upper end of the atomizing host 2 will come into contact with the liquid guiding assembly 108 and generate atomized liquid by heating the atomized liquid on the liquid guiding assembly 108. The atomized liquid rises from the through hole of the sleeve assembly 105 to the mouthpiece 102.

[0116] The above describes the atomizing cartridge 1 in the embodiments of this application in detail. Since the atomizing cartridge 1 does not contain expensive atomizing components, but is made of inexpensive liquid storage cup 103, sleeve assembly 105 and upper cover shell 101, the atomizing cartridge 1 can be used as a disposable product. After the user finishes using it, a new atomizing cartridge 1 can be directly replaced. It has a high cost performance and thus further improves the performance of the atomizing cartridge and electronic atomizing device 3.

[0117] The electronic atomizing device 3 in the embodiments of this application is further described below. Please refer to [link to relevant documentation]. Figure 2 , Figure 3 as well as Figure 7 , Figure 8 , Figure 7 This is a cross-sectional schematic diagram of the electronic atomizing device in the separated state of the atomizing bullet and the atomizing host in the embodiments of this application. Figure 8 This is a three-dimensional cross-sectional view of the electronic atomizing device 3 in the embodiment of this application, in the state where the atomizing bullet and the atomizing host are separated.

[0118] The electronic atomizing device 3 includes the structure of all the aforementioned atomizing bullets 1 embodiments, and can also achieve the technical effects of the aforementioned atomizing bullets 1.

[0119] The electronic atomizing device 3 also includes:

[0120] The atomizing unit 2 and the atomizing cartridge 1 are separate structures. The atomizing unit 2 includes an atomizing component 202, which includes:

[0121] The atomizing core 201 is located at the upper end of the atomizing host 2, and the upper end of the atomizing core 2 is set as a plane.

[0122] Furthermore, the coefficient of friction of the outer peripheral wall of the sleeve assembly 105 is the first coefficient of friction, and the coefficient of friction of the outer peripheral wall of the atomizing core 201 is the second coefficient of friction. The second coefficient of friction is greater than the first coefficient of friction, meaning that the frictional force of the outer peripheral wall of the atomizing core 201 is greater than that of the outer peripheral wall of the sleeve assembly 105. Thus, when the atomizing cartridge 1 is subjected to a pulling force in the direction away from the nozzle 102, the entire sleeve assembly 105 will be driven and moved in the direction away from the nozzle 102. Consequently, the liquid inlet 106 moves to a position where it is in close contact with the liquid inlet baffle 107, and the liquid inlet 106 is blocked by the liquid inlet baffle 107. Simultaneously, the liquid reservoir outlet 104 is in close contact with the first friction element 112 of the outer peripheral wall of the sleeve assembly 105, and the path of the atomized liquid 109 flowing into the liquid guiding assembly 108 is interrupted.

[0123] Preferably, the outer peripheral wall of the sleeve assembly 105 is further covered with a first friction element 112, which is in close contact with the liquid hole baffle 107 and its outer peripheral wall. The outer peripheral wall of the atomizing core 201 located at the upper end of the atomizing host 2 is covered with a second friction element (not shown). Furthermore, the second friction coefficient of the second friction element is greater than the first friction coefficient of the first friction element 112. Thus, when the atomizing bullet 1 is subjected to a downward pulling force, the friction force generated by the second friction element on the outer peripheral wall of the atomizing core 201 is greater than the friction force generated by the first friction element 112 wrapped on the outer peripheral wall of the sleeve assembly 105. Therefore, when the entire sleeve assembly 105 is subjected to a pulling force in the direction away from the nozzle 102, the entire sleeve assembly 105 will be driven to move away from the nozzle 102. As a result, the liquid inlet 106 moves to a position that is in close contact with the liquid hole baffle 107. The liquid inlet 106 is blocked by the liquid hole baffle 107. At the same time, the liquid storage cup outlet 104 is in close contact with the first friction element 112 on the outer peripheral wall of the sleeve assembly 105, and the path of the atomizing liquid 109 flowing to the liquid guiding assembly 108 is blocked.

[0124] Furthermore, the material of the first friction element 112 can be different from or the same as the material of the second friction element; no specific limitation is made here. When the materials of the first friction element 112 and the second friction element are the same, the first coefficient of friction obtained from the texture of the first friction element 112 is greater than the second coefficient of friction obtained from the texture of the second friction element. For example, the first friction element 112 and the second friction element can be made of two different silicone materials with different coefficients of friction, or one friction element can be made of silicone material and the other of plastic material, with different friction technologies. Alternatively, they can both be made of the same silicone material, but with different textures, resulting in different coefficients of friction.

[0125] Optionally, the detachable structure of the electronic atomizing device can be a pluggable detachable structure, or a rotatable or detachable detachable structure; no specific limitation is made here. After the outer tube 1053 of the atomizing cartridge is fitted with the atomizing core 201, the atomizing cartridge 1 and the atomizing host 2 are installed as a whole.

[0126] In addition, the atomizing core 201 can be a metal conductor atomizing core, an ultrasonic atomizing core, or a surface acoustic wave atomizing core; the specific type is not limited here.

[0127] In this embodiment, the atomizing host 2 can be a cigarette holder, an aromatherapy diffuser for relieving fatigue, or a medical liquid atomizing host for treating throat, trachea, and lung diseases; the specific type is not limited here.

[0128] It should be noted that the electronic atomizing device in the embodiments of this application can be an electronic cigarette, an aromatherapy electronic terminal, or an atomizing medical device, and no specific limitation is made here.

[0129] The electronic atomizing device 3 in this embodiment consists of a detachable atomizing cartridge 1 and an atomizing host 2. The atomizing cartridge 1 does not contain an atomizing component 202. When the electronic atomizing device 3 is shipped from the factory or not in use, the atomizing cartridge 1 and the atomizing host 2 are in a separate state, and the liquid storage cup outlet 104 is in a closed state. Only when the atomizing cartridge 1 and the atomizing host 2 are combined into one unit during use will the liquid storage cup outlet 104 be in a conductive state. This not only protects the atomizing component 202 and the liquid guiding component 108 from being wetted and corroded by the atomizing liquid 109 that has been wrapped for a long time, thus extending the service life of the electronic atomizing device 3, but also reduces leakage and keeps the electronic atomizing device clean, hygienic and environmentally friendly. Furthermore, since the atomizing cartridge 1 does not contain an atomizing component 202, it is inexpensive and can be used as a disposable product, thus improving the performance and practicality of the electronic atomizing device 3.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent structural substitutions can be made to some of the technical features and figures. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
