In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Please see Figures 1 to 5 As shown, this utility model embodiment provides an atomizer 10, including an oil tank assembly 1 and an atomizing assembly 2. A locking structure 3 is provided between the oil tank assembly 1 and the atomizing assembly 2. The locking structure 3 has a locked state and an unlocked state. In the unlocked state, the oil tank assembly 1 and the atomizing assembly 2 can be detached. In the locked state, the oil tank assembly 1 and the atomizing assembly 2 are fixedly connected.

[0034] In this embodiment of the invention, a locking structure 3 is provided between the oil tank assembly 1 and the atomizing assembly 2. By locking and unlocking the locking structure 3, the oil tank assembly 1 and the atomizing assembly 2 can be separated or fixedly connected. That is, the locking structure 3 enables a detachable connection between the oil tank assembly 1 and the atomizing assembly 2. This allows the oil tank assembly 1 to be replaced promptly when the atomizing liquid inside is used up, while the atomizing assembly 2 can be reused, saving operating costs and being environmentally friendly. Furthermore, after the locking structure 3 is unlocked, the oil tank assembly 1 and the atomizing assembly 2 are separated, which facilitates separate transportation and individual storage of the oil tank assembly 1 and the atomizing assembly 2.

[0035] In some embodiments, the locking structure 3 is configured to undergo elastic deformation under external force to unlock the oil tank assembly 1 and the atomizing assembly 2.

[0036] In some embodiments, the locking structure 3 includes a first latching structure 31 disposed on the oil tank assembly 1 and a second latching structure 32 disposed on the atomizing assembly 2. In the locked state, the first latching structure 31 and the second latching structure 32 are connected.

[0037] Specifically, a first snap-fit ​​structure 31 is provided in the oil tank assembly 1, and a second snap-fit ​​structure 32 is provided in the atomizing assembly 2. When the locking structure 3 is locked, the first snap-fit ​​structure 31 and the second snap-fit ​​structure 32 are connected to fix the oil tank assembly 1 and the atomizing assembly 2.

[0038] Furthermore, the first snap-fit ​​structure 31 includes a snap-fit ​​hole 11 or a snap-fit ​​protrusion 21 arranged circumferentially; the second snap-fit ​​structure 32 includes a snap-fit ​​protrusion 21 corresponding to the snap-fit ​​hole 11, or a snap-fit ​​hole 11 corresponding to the snap-fit ​​protrusion 21; in the locked state, the snap-fit ​​protrusion 21 snaps into the snap-fit ​​hole 11.

[0039] In some embodiments, the first snap-fit ​​structure 31 includes a snap-fit ​​hole 11 formed in the oil tank assembly 1, and the second snap-fit ​​structure 32 includes a snap-fit ​​protrusion 21 protruding from the outside of the atomizing assembly 2. Thus, by snapping the snap-fit ​​protrusion 21 into the snap-fit ​​hole 11, a fixed connection between the atomizing assembly 2 and the oil tank assembly 1 can be achieved.

[0040] In some embodiments, the first snap-fit ​​structure 31 includes a snap-fit ​​protrusion 21 protruding from the inside of the oil tank assembly 1, and the second snap-fit ​​structure 32 includes a snap-fit ​​hole 11 opened in the atomizing assembly 2. The snap-fit ​​protrusion 21 can also be snapped into the snap-fit ​​hole 11, thereby achieving a fixed connection between the atomizing assembly 2 and the oil tank assembly 1.

[0041] Furthermore, the atomizing component 2 is also provided with a spring arm 22, and the second snap-fit ​​structure 32 is elastically connected to the atomizing component 2 and abuts against the inner side of the spring arm 22, or the second snap-fit ​​structure 32 is integrally provided with the spring arm 22.

[0042] In some embodiments, the atomizing component 2 includes a spring arm 22, the free end of which abuts against the free end of the second locking structure 32. The second locking structure 32 is elastically connected to the atomizing component 2. Thus, by pressing the spring arm 22, the spring arm 22 can move the second locking structure 32, thereby separating the second locking structure 32 from the first locking structure 31, thereby unlocking the locking structure 3 and allowing the atomizing component 2 to be disassembled from the oil tank component 1. When the spring arm 22 is released and the second locking structure 32 is aligned with the first locking structure 31, the second locking structure 32 can be connected to the first locking structure 31, thereby locking the locking structure 3 and connecting the atomizing component 2 and the oil tank component 1.

[0043] For example, along the axial direction, with the oil tank assembly 1 on top and the atomizing assembly 2 on the bottom, the free end of the elastic arm 22 can face upwards relative to its fixed end, while the free end of the second snap-fit ​​structure 32 can face downwards relative to its fixed end. Furthermore, in this embodiment of the invention, the axial direction is parallel to... Figure 1 The direction parallel to the X-axis.

[0044] Additionally, it is understandable that the second snap-fit ​​structure 32 can be a structure with a snap-fit ​​protrusion 21 or a snap-fit ​​hole 11.

[0045] In some embodiments, the elastic arm 22 and the second locking structure 32 can be integrally provided, which is equivalent to the second locking structure 32 being provided at one location of the elastic arm 22. Similarly, by pressing the elastic arm 22, the second locking structure 32 and the first locking structure 31 can be separated or connected to achieve the unlocking or locking of the locking structure 3.

[0046] Similarly, the second snap-fit ​​structure 32 can be a structure with a snap-fit ​​protrusion 21 or a snap-fit ​​hole 11.

[0047] Furthermore, the elastic arm 22 is provided with a pressing part 221, and the side wall of the oil tank assembly 1 is provided with a clearance opening 12, through which the pressing part 221 is exposed to the outside of the oil tank assembly 1.

[0048] In some embodiments, the pressing part 221 of the elastic arm 22 is disposed in the clearance opening 12 and abuts against the second locking structure 32 on its inner side, so that the pressing part 221 can be exposed to the outside, making it convenient for the user to perform the pressing action, and can also drive the second locking structure 32 away from the first locking structure 31.

[0049] In some embodiments, the second snap-fit ​​structure 32 and the elastic arm 22 are integrally formed. A pressing part 221 can be provided in the elastic arm 22 at a position spaced apart from the snap protrusion 21 or the snap hole 11, and the pressing part 221 is located at the clearance opening 12. In this way, it is also convenient for the user to perform the pressing action, and the second snap-fit ​​structure 32 can be moved away from the first snap-fit ​​structure 31 by pressing.

[0050] For example, the side of the pressing part 221 exposed to the outside may be provided with an anti-slip structure, which can improve the reliability of pressing.

[0051] Furthermore, in some embodiments, the first snap-fit ​​structure 31 includes a snap fastener elastically connected to the atomizing component 2, and the second snap-fit ​​structure 32 includes a slot corresponding to the snap fastener. In the locked state, the snap fastener is snapped into the slot, and the snap fastener is exposed to the outside of the atomizing component 2 through the slot.

[0052] In some embodiments, the elastic arm 22 may be disposed on the oil tank assembly 1 instead of the atomizing component 2. Specifically, the atomizing component 2 is partially disposed within the oil tank assembly 1 along the axial direction and partially protrudes from the oil tank assembly 1. A slot may be formed on the portion of the atomizing component 2 protruding from the oil tank assembly 1, and a corresponding buckle protrudes from the oil tank assembly 1 along the axial direction. In this way, the buckle can be exposed to the outside through the slot for easy pressing by the user. When locked, the buckle engages in the slot, thus achieving a fixed connection between the oil tank assembly 1 and the atomizing component 2. When unlocked, the oil tank assembly 1 and the atomizing component 2 can be disassembled and separated by pressing the buckle.

[0053] For example, an anti-slip structure can be provided on the side of the buckle away from the atomizing component 2 to improve the reliability of pressing.

[0054] In some specific embodiments, the atomizing component 2 includes an atomizing bracket 25, a base 26 connected to the end of the atomizing bracket 25 away from the oil tank component 1, and an oil guide 28 and a heating element 27 fixed between the atomizing bracket 25 and the base 26. The oil guide 28 is in liquid communication with the oil tank component 1. An elastic arm 22 is elastically connected to the base 26 and extends from the base 26 to the atomizing bracket 25. A second snap-fit ​​structure 32 is elastically connected to the atomizing bracket 25 and extends from the atomizing bracket 25 to the base 26. That is, the elastic arm 22 abuts against the second snap-fit ​​structure 32, and the elastic arm 22 and the second snap-fit ​​structure 32 are elastically connected to one of the components of the atomizing component 2, respectively. Compared with the structure in which the elastic arm 22 and the second snap-fit ​​structure are integrated, this arrangement allows for better adjustment of the pressing force according to the space of the atomizing component 2, and better adjustment of the setting position of the pressing part 221, the snap protrusion 21, or the snap hole 11, etc.

[0055] Understandably, in other embodiments, the elastic arm 22 and the second snap-fit ​​structure 32 may also be elastically connected to other components of the atomizing assembly 2, and this embodiment of the present invention does not impose specific limitations.

[0056] Furthermore, in some embodiments, the oil tank assembly 1 has a liquid storage chamber 13, the liquid storage chamber 13 has at least one opening at one end facing the atomizing assembly 2 along the axial direction, a valve plate 14 is disposed in the opening, and the atomizing assembly 2 is provided with a liquid guide tube 23, which is inserted into the at least one opening to open the valve plate 14.

[0057] Specifically, the oil tank assembly 1 includes an oil cup bracket. A snap-fit ​​or second snap-fit ​​structure 32 can be disposed on the periphery of the oil cup bracket, and the inner side of the oil cup bracket has a liquid storage chamber 13. Along the axial direction, there is an opening at one end of the liquid storage chamber 13, and a valve plate 14 is provided at the opening. This prevents the atomized liquid in the liquid storage chamber 13 from flowing out, allowing the oil tank assembly 1 to be dispensed and transported independently. When assembling the oil tank assembly 1 and the atomizing assembly 2, the liquid guide tube 23 of the atomizing assembly 2 can be inserted into the opening, and the valve plate can be opened, allowing the atomized liquid in the liquid storage chamber 13 to flow to the atomizing assembly 2 through the liquid guide tube 23.

[0058] Furthermore, in some embodiments, the oil tank assembly 1 has two spaced openings at the same end of the liquid storage chamber 13, and the atomizing assembly 2 is also provided with a return air pipe 24 spaced apart from the liquid guide pipe 23. The liquid guide pipe 23 and the return air pipe 24 are respectively inserted into the two openings to open the corresponding valve plate 14.

[0059] Specifically, along the axial direction, a liquid guide pipe 23 and a return air pipe 24 are arranged at intervals on the side of the atomizing component 2 near the oil tank component 1. During assembly, the two openings of the oil tank component 1 can be facing upwards first, and then the liquid guide pipe 23 can be inserted into one of the openings to open the corresponding valve plate 14; at the same time, the return air pipe 24 can be inserted into the other opening, which can also open the corresponding valve plate 14. In use, the opening of the oil tank component 1 can be facing downwards, so that the atomizing liquid in the liquid storage chamber 13 can flow along the valve plate 14 to the liquid guide pipe 23 for heating and atomization; while the airflow can flow through the return air pipe 24 to the liquid storage chamber 13 to realize the ventilation of the liquid storage chamber 13.

[0060] Furthermore, in some specific embodiments, the transverse cross-sectional area of ​​the liquid guide tube 23 can be a circle with a uniform cross-sectional area, which facilitates the smooth flow of the atomized liquid. Additionally, the transverse cross-sectional area of ​​the return air tube 24 is smaller than that of the liquid guide tube 23, which allows for ventilation while preventing leakage of the atomized liquid from the storage chamber 13 through the return air tube 24. Moreover, along the axial direction from the oil tank assembly 1 to the atomizing assembly 2, the transverse cross-sectional area of ​​the return air tube 24 can gradually decrease, thus ensuring ventilation while also storing any leakage to a certain extent.

[0061] Furthermore, in some embodiments, the axial oil reservoir assembly 1 also has an assembly cavity 15 located on the side of the valve plate 14 opposite to the liquid storage cavity 13; the atomizing assembly 2 includes a mounting base, a heating element 27, an oil guide 28, and an air passage 29, with the mounting base assembled in the assembly cavity 15; the heating element 27 is disposed on the air passage 29, the mounting base is provided with an installation space, the air passage 29 and the oil guide 28 are clamped in the installation space, the liquid guide tube 23 is disposed on the mounting base, and the oil guide 28 communicates with the liquid storage cavity 13 through the liquid guide tube 23.

[0062] Specifically, the oil tank assembly 1 includes an oil cup support. Along the axial direction, the oil cup support sequentially includes a liquid storage chamber 13 and an assembly chamber 15. The atomizing assembly 2 is partially located within the assembly chamber 15 along the axial direction, and partially protrudes from the end of the assembly chamber 15 away from the liquid storage chamber 13. The mounting base is located within the assembly chamber 15 and also forms an installation space. The oil guide 28, the air passage component 29, and the heating element 27 assembled on the air passage component 29 are clamped in the installation space, allowing the oil guide 28 and the heating element 27 to be pressed together. Furthermore, a liquid guide pipe 23 is disposed on the mounting base. The oil guide 28 communicates with the liquid storage chamber 13 through the liquid guide pipe 23. Thus, the atomizing liquid can flow from the liquid storage chamber 13 to the oil guide 28 through the liquid guide pipe 23, and can then be heated and atomized by the heating element 27. Furthermore, in some embodiments, the heating element 27 includes a heating part 271 and a support part 272. One side of the air passage 29 is provided with an atomizing groove 291 extending axially to both ends. The heating part 271 covers the atomizing groove 291 and is attached to the oil guide body 28. The support part 272 bends and extends from the heating part 271 to the periphery of the air passage 29 to the other side of the air passage 29.

[0063] Specifically, a groove is provided on one side of the air passage component 29, the heating part 271 of the heating element 27 is fixedly assembled on the air passage component 29, and the heating element 27 covers the groove. The heating element 27 heats the atomizing liquid of the oil guide body 28, so that the groove forms an atomizing groove 291, and atomized gas can be generated in the atomizing groove 291. Furthermore, the air passage component 29 can primarily have a cubic structure. It can have a first side and a second side arranged opposite each other, and two third sides orthogonally arranged to the first and second sides. The heating element 27's heating portion 271 is located on the first side of the air passage component 29. One support portion 272 of the heating element 27 bends from the first side of the heating element 27 to one of the third sides of the air passage component 29 and continues to bend to the second side. The other support portion 272 of the heating element 27 bends from the first side of the heating element 27 to the other third side of the air passage component 29 and continues to bend to the second side. This allows the heating element 27 to be stably assembled into the air passage component 29, ensuring the structural stability of the heating element 27 and preventing deformation or warping. It also allows the heating portion 271 of the heating element 27 and the oil guide 28 to fit together effectively. Additionally, reducing the lateral dimension of the heating element 27 along its extension direction improves the overall compactness of the atomizing assembly 2, facilitating miniaturization design.

[0064] In some specific examples, the air duct 29 can be made of a rigid material, such as ceramic or glass, or a soft material, such as silicone. To ensure better resistance to deformation when the heating element 27 is fitted with the air duct 29, the air duct 29 can be made of a rigid material such as ceramic or glass.

[0065] Furthermore, in some specific embodiments, the oil cup support also includes an outlet pipe 16 located in the middle, with the liquid storage chamber 13 surrounding the outer periphery of the outlet pipe 16. The outlet pipe 16 and the atomizing groove 291 are aligned axially, so that the atomized gas generated in the atomizing groove 291 can flow to the outlet pipe 16 and then to the outside.

[0066] Furthermore, in some embodiments, the mounting base includes an atomizing bracket 25 and a base 26. The atomizing bracket 25 has a mounting groove 252 extending through the end of the atomizing bracket 25 away from the liquid storage chamber 13. The base 26 is disposed at the end of the atomizing bracket 25 away from the liquid storage chamber 13, so as to enclose the mounting groove 252 to form an installation space. The base 26 has an axially extending abutment portion 261, which is fitted into the mounting groove 252 and clamped between the inner wall of the mounting groove 252 and the air passage component 29. A liquid guide tube 23 is disposed on the atomizing bracket 25, and the atomizing bracket 25 also has a liquid guide channel communicating with the liquid guide tube 23. The liquid guide tube 23 is in liquid communication with the oil guide body 28 through the liquid guide channel.

[0067] Specifically, the mounting base can be formed by assembling an atomizer bracket 25 and a base 26. The atomizer bracket 25 is provided with a mounting groove 252, and the base 26 is connected to the atomizer bracket 25 and forms an installation space with the mounting groove 252, allowing the wicking element 28 and the airflow component 29 to be assembled within the installation space. Furthermore, the base 26 specifically includes a supporting portion 261 assembled in the mounting groove 252, and the supporting portion 261 is clamped between the inner wall of the mounting groove 252 and the airflow component 29. That is, the supporting portion 261 of the base 26 can act on the airflow component 29, ensuring a tight contact connection between the heating element 27 and the wicking element 28 disposed in the airflow component 29. In addition, the liquid guide tube 23 is specifically disposed on the atomizing bracket 25, and the atomizing bracket 25 is also provided with a liquid guide channel communicating with the liquid guide tube 23. Thus, the liquid guide tube 23 can be connected to the oil guide body 28 through the liquid guide channel, so that the atomizing liquid in the liquid storage chamber 13 can flow through the liquid guide tube 23 to the liquid guide channel, and then flow through the liquid guide channel to the oil guide body 28.

[0068] Furthermore, in some specific embodiments, the return air pipe 24 is disposed on the atomizing bracket 25, and the supporting part 261 and the return air pipe 24 are aligned axially. The side of the air passage 29 facing away from the oil guide body 28 abuts against the supporting part 261. External airflow can flow to the return air pipe 24 through the gap between the supporting part 261 and the mounting groove 252 to balance the air pressure in the liquid storage chamber 13.

[0069] Furthermore, in some specific embodiments, the atomizing bracket 25 has a liquid collection groove 251 that extends through the atomizing bracket 25 toward the liquid storage chamber 13 and is connected to the liquid guide tube 23. The side wall of the liquid collection groove 251 is also provided with a liquid guide hole that is connected to the mounting groove 252. The liquid guide channel includes the liquid guide hole and the liquid collection groove 251. The base 26 is also provided with a sealing part 262 that extends axially and passes through one end of the liquid collection groove 251.

[0070] Specifically, a liquid collection tank 251 connected to the liquid guide pipe is also provided on the atomizing bracket 25. The liquid guide pipe 23 and the liquid collection tank 251 can be aligned axially. Furthermore, a liquid guide hole communicating with the mounting groove 252 can be opened on the side wall of the liquid collection tank 251. In this way, the atomizing liquid in the liquid storage chamber 13 can flow to the liquid collection tank 251 through the liquid guide pipe 23, and then flow to the mounting groove 252 through the liquid guide hole. In addition, by providing the liquid collection tank 251, the liquid storage capacity of the atomizing component 2 can be improved. When the oil tank component 1 reaches the end of its use or needs to be replaced, the remaining atomizing liquid can be concentrated in the liquid collection tank 251, reducing the residual oil amount.

[0071] In addition, a sealing portion 262 is provided on the base, spaced apart from the supporting portion 261. The side of the air passage 29 facing away from the oil guide body 28 abuts against the supporting portion 261. Therefore, the side of the air passage 29 where the oil guide body 28 and the heating element 27 are located faces the sealing portion 262. The sealing portion 262 passes through one end of the liquid collection tank 251. Therefore, the side of the air passage 29 where the oil guide body 28 and the heating element 27 are located faces the side wall of the liquid collection tank 251. That is, the liquid guide hole of the liquid collection tank 251 can be directly connected to the oil guide body 28. In this way, the atomized liquid in the liquid storage chamber 13 can flow sequentially through the liquid guide pipe 23, the liquid collection tank 251, and the liquid guide hole, and finally flow to the oil guide body 28. In addition, the sealing portion can seal the liquid collection tank 251, thereby preventing the atomized liquid in the liquid collection tank 251 from leaking out.

[0072] Furthermore, in some specific embodiments, the base 26 is also provided with an air inlet, which is connected to the atomizing groove 291 of the air passage 29, so that external airflow can flow to the atomizing groove 291 through the air inlet.

[0073] Furthermore, in some specific embodiments, a contact structure 292 is provided on the side of the air passage 29 away from the oil guide body 28. The contact structure 292 includes a contact protrusion protruding towards the abutment portion 261, and / or the contact surface of the contact structure 292 is inclined outward along the axial direction from the atomizing assembly 2 to the oil tank assembly 1; the side of the abutment portion 261 facing the air passage 29 matches the contact structure 292.

[0074] Specifically, the support portion 272 of the heating element 27 can be provided with a through hole, and the side of the air passage component 29 opposite to the oil guide body 28 can be provided with a protrusion. The support portion 272 of the heating element 27 and the air passage component 29 can be fixedly connected by the protrusion and the through hole. Furthermore, a contact structure 292 can also be provided on the side of the air passage component 29 opposite to the oil guide body 28. The contact structure 292 can be a contact protrusion with a greater degree of protrusion than a protrusion, so that the supporting portion 261 can be assembled between the contact structure 292 of the air passage component 29 and the inner wall of the mounting groove 252.

[0075] Furthermore, the contact surface of the contact structure 292 of the air passage component 29 can also be inclined, and it is inclined outward along the axial direction from the atomizing assembly 2 towards the oil tank assembly 1. The supporting part 261 is adaptively inclined on the side facing the air passage component 29, that is, the supporting part 261 is inclined outward along the axial direction from the oil tank assembly 1 towards the atomizing assembly 2 on the side facing the air passage component 29. In this way, the two inclined surfaces can serve as guide surfaces, which is beneficial for assembling the supporting part 261 of the base 26 between the contact structure 292 of the air passage component 29 and the inner wall of the mounting groove 252.

[0076] Furthermore, in some embodiments, the inner wall of the mounting groove 252 may also be inclined along the axial direction, and inclined outward along the axial direction from the atomizing component 2 to the oil tank component 1. The lateral dimension of the space between the contact structure 292 of the air passage component 29 and the inner wall of the mounting groove 252 gradually decreases, so as to guide the assembly of the supporting part 261.

[0077] Furthermore, in some embodiments, an electronic atomizing device includes a battery rod 20 and an atomizer 10, wherein the battery rod 20 and the atomizer 10 are detachably connected.

[0078] In this embodiment of the invention, the atomizing component 2 and the oil tank component 1 of the atomizer are detachably connected, and the battery rod and the atomizer are also detachably connected. In this way, the electronic atomizing device can be set up in three sections, that is, the liquid storage part, the atomizing part and the power supply part of the electronic atomizing device are divided into three parts, which can be stored and transported separately, and can be replaced according to actual needs, so that the functional parts can be reused, which is energy-saving and environmentally friendly.
