[0033] Please refer to Figures 1 to 5As shown in the figure, an embodiment of the present invention provides an atomizer 10, which includes an oil storage component 1 and an atomization component 2. A locking structure 3 is provided between the oil storage component 1 and the atomization component 2. The locking structure 3 has a locked state and an unlocked state. In the unlocked state, the oil storage component 1 and the atomization component 2 can be detachably separated; in the locked state, the oil storage component 1 and the atomization component 2 are fixedly connected.

[0034] In the embodiment of the present invention, a locking structure 3 is provided between the oil storage component 1 and the atomization component 2. By locking and unlocking the locking structure 3, the oil storage component 1 and the atomization component 2 can be separated or fixedly connected, that is, the detachable connection between the oil storage component 1 and the atomization component 2 can be realized through the locking structure 3. In this way, after the atomization liquid inside the oil storage component 1 is used up, a new oil storage component 1 can be replaced in time, and the atomization component 2 can be reused, which can save the use cost and has environmental protection. In addition, after the locking structure 3 is unlocked, the oil storage component 1 and the atomization component 2 are separately arranged. In this way, it is beneficial to the separate transportation and individual storage of the oil storage component 1 and the atomization component 2.

[0035] In some embodiments, the locking structure 3 is configured to elastically deform under an external force to enable the oil storage component 1 and the atomization component 2 to be in the unlocked state.

[0036] In some embodiments, the locking structure 3 includes a first clamping structure 31 provided on the oil storage component 1 and a second clamping structure 32 provided on the atomization component 2. In the locked state, the first clamping structure 31 is connected to the second clamping structure 32.

[0037] Specifically, the first clamping structure 31 is provided on the oil storage component 1, and the second clamping structure 32 is provided on the atomization component 2. When the locking structure 3 is locked, the first clamping structure 31 and the second clamping structure 32 are connected to fixedly connect the oil storage component 1 and the atomization component 2.

[0038] Further, the first clamping structure 31 includes a clamping hole 11 or a clamping protrusion 21 provided along the circumferential direction; the second clamping structure 32 includes a clamping protrusion 21 corresponding to the clamping hole 11 or a clamping hole 11 corresponding to the clamping protrusion 21; in the locked state, the clamping protrusion 21 is clamped in the clamping hole 11.

[0039] In some embodiments, the first clamping structure 31 includes a clamping hole 11 opened on the oil storage component 1, and the second clamping structure 32 includes a clamping protrusion 21 protruding from the outside of the atomization component 2. In this way, by clamping the clamping protrusion 21 into the clamping hole 11, the fixed connection between the atomization component 2 and the oil storage component 1 can be realized.

[0040] In some embodiments, the first latching structure 31 includes a latching protrusion 21 protruding from the inside of the oil storage assembly 1, and the second latching structure 32 includes a latching hole 11 formed in the atomization assembly 2. Similarly, the latching protrusion 21 can be latched in the latching hole 11 to achieve the fixed connection between the atomization assembly 2 and the oil storage assembly 1.

[0041] Furthermore, the atomization assembly 2 is further provided with an elastic arm 22. The second latching structure 32 is elastically connected to the atomization assembly 2 and abuts against the inner side of the elastic arm 22, or the second latching structure 32 is integrally provided with the elastic arm 22.

[0042] In some embodiments, the atomization assembly 2 includes an elastic arm 22. The free end of the elastic arm 22 abuts against the free end of the second latching structure 32, and the second latching structure 32 is elastically connected to the atomization assembly 2. In this way, by pressing the elastic arm 22, the elastic arm 22 can drive the second latching structure 32 to move, so that the second latching structure 32 is separated from the first latching structure 31, thereby realizing the unlocking of the latching structure 3, and the atomization assembly 2 can be detached from the oil storage assembly 1; when the elastic arm 22 is released and the second latching structure 32 is aligned with the first latching structure 31, the second latching structure 32 can be connected to the first latching structure 31, realizing the locking of the latching structure 3, and the atomization assembly 2 and the oil storage assembly 1 can be connected.

[0043] Exemplarily, along the axial direction, with the oil storage assembly 1 on the top and the atomization assembly 2 on the bottom, the free end of the elastic arm 22 can face upward relative to its fixed end, while the free end of the second latching structure 32 can face downward relative to its fixed end. In addition, in the embodiments of the present invention, the axial direction is parallel to Figure 1 the direction parallel to the X axis in

[0044] In addition, it can be understood that the second latching structure 32 can be a structure provided with a latching protrusion 21 or a latching hole 11.

[0045] In some embodiments, the elastic arm 22 and the second latching structure 32 can be integrally provided, which is equivalent to providing the second latching structure 32 at one place of the elastic arm 22. Similarly, by pressing the elastic arm 22, the second latching structure 32 can be driven to be separated from or connected to the first latching structure 31, so as to realize the unlocking or locking of the latching structure 3.

[0046] Similarly, the second latching structure 32 can be a structure provided with a latching protrusion 21 or a latching hole 11.

[0047] Furthermore, the elastic arm 22 is provided with a pressing portion 221, and an avoidance opening 12 is formed in the side wall of the oil storage assembly 1. The pressing portion 221 is exposed outside the oil storage assembly 1 through the avoidance opening 12.

[0048] In some embodiments, the pressing portion 221 of the elastic arm 22 is disposed in the avoidance opening 12 and abuts against the second latching structure 32 on the inner side, so that the pressing portion 221 can be exposed to the outside to facilitate the user's pressing action, and can also drive the second latching structure 32 away from the first latching structure 31.

[0049] In some embodiments, the second latching structure 32 and the elastic arm 22 are integrally provided. A pressing portion 221 may protrude outward at a position spaced from the latching protrusion 21 or the latching hole 11 in the elastic arm 22, and the pressing portion 221 is disposed at the avoidance opening 12. In this way, it is also convenient for the user to perform a pressing action, and the second latching structure 32 can be driven away from the first latching structure 31 by pressing.

[0050] Exemplarily, an anti-slip structure may be provided on the side of the pressing portion 221 exposed to the outside, which can improve the pressing reliability.

[0051] Further, in some embodiments, the first latching structure 31 includes a buckle elastically connected to the atomization assembly 2, and the second latching structure 32 includes a card slot corresponding to the buckle. In the locked state, the buckle is latched in the card slot, and the buckle is exposed outside the atomization assembly 2 through the card slot.

[0052] In some embodiments, the elastic arm 22 may not be disposed on the atomization assembly 2, but on the oil tank assembly 1. Specifically, the atomization assembly 2 is partially disposed in the oil tank assembly 1 along the axial direction and partially protrudes outside the oil tank assembly 1. A card slot may be formed in the part of the atomization assembly 2 protruding outside the oil tank assembly 1, and a buckle protrudes axially corresponding to the oil tank assembly 1. In this way, the buckle can be exposed to the outside through the card slot, facilitating the user to press. When locked, the buckle is latched in the card slot, and the fixed connection between the oil tank assembly 1 and the atomization assembly 2 can be realized. When unlocking, by pressing the buckle, the oil tank assembly 1 and the atomization assembly 2 can be disassembled and separated.

[0053] Exemplarily, an anti-slip structure may be provided on the side of the buckle facing away from the atomization assembly 2, which can improve the pressing reliability.

[0054] In some specific embodiments, the atomization assembly 2 includes an atomization bracket 25, a base 26 connected to one end of the atomization bracket 25 away from the oil storage assembly 1, and a liquid guide body 28 and a heating element 27 fixed between the atomization bracket 25 and the base 26. The liquid guide body 28 is in liquid communication with the oil storage assembly 1; the elastic arm 22 is elastically connected to the base 26 and extends from the base 26 towards the atomization bracket 25; the second clamping structure 32 is elastically connected to the atomization bracket 25 and extends from the atomization bracket 25 towards the base 26. That is to say, the elastic arm 22 abuts against the second clamping structure 32, and the elastic arm 22 and the second clamping structure 32 are respectively elastically connected to one of the components of the atomization assembly 2. Compared with the structure in which the elastic arm 22 and the second clamping are integrally arranged, such a setting can better adjust the pressing elastic force according to the space of the atomization assembly 2, and can better adjust the setting positions of the pressing part 221, the clamping convex 21 or the clamping hole 11, etc.

[0055] It can be understood that in other embodiments, the elastic arm 22 and the second clamping structure 32 can also be respectively elastically connected to other components of the atomization assembly 2, and the embodiments of the present invention do not make specific limitations.

[0056] Further, in some embodiments, the oil storage assembly 1 has a liquid storage cavity 13. At least one opening is provided at one end of the liquid storage cavity 13 along the axial direction towards the atomization assembly 2. A valve sheet 14 is arranged in the opening. The atomization assembly 2 is provided with a liquid guide pipe 23, and the liquid guide pipe 23 is inserted into at least one opening to open the valve sheet 14.

[0057] Specifically, the oil storage assembly 1 includes an oil cup bracket. The buckle or the second clamping structure 32 can be arranged on the periphery of the oil cup bracket, and the inner side of the oil cup bracket has a liquid storage cavity 13. Along the axial direction, an opening is further provided at one end of the liquid storage cavity 13, and a valve sheet 14 is arranged at the opening. In this way, the atomized liquid in the liquid storage cavity 13 can be prevented from flowing outwards, and the oil storage assembly 1 can be separately taken out of the warehouse and transported. When assembling the oil storage assembly 1 and the atomization assembly 2, the liquid guide pipe 23 of the atomization assembly 2 can be inserted into the opening to open the valve sheet, so that the atomized liquid in the liquid storage cavity 13 can flow towards the atomization assembly 2 through the liquid guide pipe 23.

[0058] Further, in some embodiments, two spaced openings are provided at the same end of the liquid storage cavity 13 of the oil storage assembly 1. The atomization assembly 2 is further provided with a return air pipe 24 spaced 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 sheets 14.

[0059] Specifically, along the axial direction, a liquid guide tube 23 and an air return tube 24 are arranged at intervals on one side of the atomizer assembly 2 close to the oil tank assembly 1. During assembly, the two openings of the oil tank assembly 1 can be facing upwards first, and then the liquid guide tube 23 can be inserted into one of the openings, so that the corresponding valve plate 14 can be opened; at the same time, the air return tube 24 can be inserted into the other opening, and the corresponding valve plate 14 can also be opened. During use, the opening of the oil tank assembly 1 can be facing downwards, so that the atomized liquid in the liquid storage chamber 13 can flow along the valve plate 14 to the liquid guide tube 23 for heating and atomization; and the air flow can flow to the liquid storage chamber 13 through the air return tube 24 to achieve 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 that is equal everywhere, so that it is conducive to the smooth flow of the atomized liquid. In addition, the transverse cross-sectional area of ​​the return air pipe 24 is smaller than the transverse cross-sectional area of ​​the liquid guide tube 23, which can not only achieve ventilation, but also prevent the atomized liquid in the liquid storage chamber 13 from leaking out through the return air pipe 24. In addition, along the axial direction, from the oil tank component 1 to the atomization component 2, the transverse cross-sectional area of ​​the return air pipe 24 can be gradually reduced, so that while ensuring ventilation, it can also store leaked liquid to a certain extent.

[0061] Furthermore, in some embodiments, the oil tank assembly 1 also has an assembly cavity 15 along the axial direction, which is located on the side of the valve plate 14 away from the liquid storage cavity 13; the atomization assembly 2 includes a mounting seat, a heating element 27, an oil guide body 28 and an airway component 29, and the mounting seat is assembled in the assembly cavity 15; the heating element 27 is arranged on the airway component 29, and the mounting seat is provided with an installation space, the airway component 29 and the oil guide body 28 are clamped in the installation space, the liquid guide tube 23 is arranged on the mounting seat, and the oil guide body 28 is connected to the liquid storage cavity 13 through the liquid guide tube 23.

[0062] Specifically, the oil tank assembly 1 includes an oil cup bracket, and along the axial direction, the oil cup bracket includes a liquid storage chamber 13 and an assembly chamber 15 in sequence, and the atomizer assembly 2 is partially located in 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. Among them, the mounting seat is in the assembly chamber 15 and the mounting seat also forms an installation space, and the oil guide body 28, the airway component 29 and the heating element 27 assembled on the airway component 29 are clamped in the installation space, so that the oil guide body 28 and the heating element 27 can be pressed and matched. In addition, the liquid guide tube 23 is arranged on the mounting seat, and the oil guide body 28 is connected with the liquid storage chamber 13 through the liquid guide tube 23, so that the atomized liquid can flow from the liquid storage chamber 13 through the liquid guide tube 23 to the oil guide body 28, so that it can be used for heating and atomization by the heating element 27. Furthermore, in some embodiments, the heating body 27 includes a heating portion 271 and a supporting portion 272, and one side of the airway component 29 is provided with an atomization groove 291 that penetrates axially to both ends, the heating portion 271 covers the atomization groove 291 and fits the oil guide body 28, and the supporting portion 272 bends from the heating portion 271 to the circumferential side of the airway component 29 and extends to the other side of the airway component 29.

[0063] Specifically, a groove is opened on one side of the airway component 29, the heating portion 271 of the heating element 27 is fixedly assembled on the airway component 29, and the heating element 27 covers the groove. The heating element 27 heats the atomized 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. In addition, the airway member 29 can be mainly in a cubic structure, and the airway member 29 can have a first side and a second side that are arranged opposite to each other, and two third sides that are arranged orthogonally to the first side and the second side. The heating portion 271 of the heating element 27 is located on the first side of the airway member 29, and one of the supporting portions 272 of the heating element 27 is bent from the first side of the heating element 27 to one of the third sides of the airway member 29 and continues to be bent to the second side. The other supporting portion 272 of the heating element 27 is bent from the first side of the heating element 27 to the other third side of the airway member 29 and continues to be bent to the second side. In this way, the heating element 27 can be stably assembled on the airway member 29, ensuring the structural stability of the heating element 27, avoiding deformation and warping of the heating element 27, and making the heating portion 271 of the heating element 27 and the oil guide body 28 can be effectively fitted. In addition, the lateral size of the heating element 27 can be reduced, and the compactness of the overall structure of the atomization assembly 2 can be improved, which is convenient for realizing a miniaturized design.

[0064] In some specific examples, the airway piece 29 can be made of hard materials, such as ceramic or glass, or can be made of soft rubber materials, such as silica gel. In order to make the heating element 27 and the airway piece 29 have better anti-deformation ability after being matched, the airway piece 29 can be made of hard materials such as ceramic or glass.

[0065] Further, in some specific embodiments, the oil cup bracket further includes an air outlet pipe 16 located in the middle, and the liquid storage cavity 13 surrounds the outer peripheral side of the air outlet pipe 16. The air outlet pipe 16 and the atomization tank 291 are arranged axially aligned. In this way, the atomized gas generated in the atomization tank 291 can flow to the air outlet pipe 16 and then flow to the outside.

[0066] Further, in some embodiments, the mounting base includes an atomization bracket 25 and a base 26. The atomization bracket 25 has a mounting groove 252 penetrating through one end of the atomization bracket 25 away from the liquid storage cavity 13; the base 26 is disposed at one end of the atomization bracket 25 away from the liquid storage cavity 13 to enclose a mounting space with the mounting groove 252; the base 26 is provided with an abutting portion 261 extending axially, and the abutting portion 261 is assembled in the mounting groove 252 and is clamped between the inner wall of the mounting groove 252 and the air passage member 29; the liquid guide pipe 23 is disposed on the atomization bracket 25, and the atomization bracket 25 is further provided with a liquid guide channel communicating with the liquid guide pipe 23, and the liquid guide pipe 23 is in liquid communication with the oil guiding body 28 through the liquid guide channel.

[0067] Specifically, the mounting base can be formed by assembling the atomization bracket 25 and the base 26. The atomization bracket 25 is provided with a mounting groove 252, and the base 26 is connected to the atomization bracket 25 and forms a mounting space with the mounting groove 252, so that the oil guiding body 28 and the air passage member 29 are assembled in the mounting space. In addition, the base 26 specifically includes an abutting portion 261 assembled in the mounting groove 252, and the abutting portion 261 is clamped between the inner wall of the mounting groove 252 and the air passage member 29. That is to say, the abutting portion 261 of the base 26 can act on the air passage member 29 to make the heating element 27 provided on the air passage member 29 and the oil guiding body 28 in close contact connection. In addition, the liquid guide pipe 23 is specifically disposed on the atomization bracket 25, and the atomization bracket 25 is further provided with a liquid guide channel communicating with the liquid guide pipe 23. In this way, the liquid guide pipe 23 can be communicated with the oil guiding body 28 through the liquid guide channel, so that the atomized liquid in the liquid storage cavity 13 can flow through the liquid guide pipe 23 to the liquid guide channel, and then flow to the oil guiding body 28 through the liquid guide channel.

[0068] Further, in some specific embodiments, the return air pipe 24 is disposed on the atomization bracket 25, and the abutting portion 261 and the return air pipe 24 are arranged axially aligned. One side of the air passage member 29 facing away from the oil guiding body 28 abuts against the abutting portion 261, and the external air flow can flow to the return air pipe 24 through the gap between the abutting portion 261 and the mounting groove 252 to balance the air pressure in the liquid storage cavity 13.

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

[0070] Specifically, a liquid collecting tank 251 connected to the liquid guiding tube is also provided on the atomizing bracket 25, the liquid guiding tube 23 and the liquid collecting tank 251 can be arranged in an axially aligned manner, and a liquid guiding hole connected to the mounting groove 252 can be opened on the side wall of the liquid collecting tank 251, so that the atomized liquid in the liquid storage chamber 13 can flow to the liquid collecting tank 251 through the liquid guiding tube 23, and then flow to the mounting groove 252 through the liquid guiding hole. In addition, by providing the liquid collecting tank 251, the liquid storage capacity of the atomizing assembly 2 can be improved. When the oil tank assembly 1 is at the end of use or needs to be replaced, the remaining atomized liquid can be concentrated in the liquid collecting tank 251 to reduce the amount of residual oil.

[0071] In addition, a sealing portion 262 is provided on the base, which is spaced apart from the abutting portion 261. The side of the airway member 29 facing away from the oil guide body 28 abuts against the abutting portion 261. Therefore, the side of the airway member 29 where the oil guide body 28 and the heating element 27 are provided faces the sealing portion 262, and the sealing portion 262 is penetrated at one end of the liquid collecting tank 251. Therefore, the side of the airway member 29 where the oil guide body 28 and the heating element 27 are provided faces the side wall of the liquid collecting tank 251, that is, the liquid guide hole of the liquid collecting 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 pass through the liquid guide tube 23, the liquid collecting tank 251, and the liquid guide hole in sequence, and finally flow to the oil guide body 28. In addition, the sealing portion can seal the liquid collecting tank 251, thereby preventing the atomized liquid in the liquid collecting tank 251 from leaking out.

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

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

[0074] Specifically, the support portion 272 of the heating element 27 may be provided with a through hole, and a convex column may be provided on the side of the air duct member 29 facing away from the oil guiding body 28. The support portion 272 of the heating element 27 and the air duct member 29 can be fixedly connected by snap - fitting the convex column and the through hole. Moreover, a contact structure 292 may be provided on the side of the air duct member 29 facing away from the oil guiding body 28, and the contact structure 292 may specifically be a contact protrusion with a greater protrusion degree than the protrusion. In this way, the abutting portion 261 can be assembled between the contact structure 292 of the air duct member 29 and the inner wall of the mounting groove 252.

[0075] In addition, the contact surface of the contact structure 292 of the air duct member 29 may be inclined, and it is inclined outward along the axial direction from the atomization assembly 2 to the oil storage assembly 1. The side of the abutting portion 261 facing the air duct member 29 is adaptively inclined, that is, the side of the abutting portion 261 facing the air duct member 29 is inclined outward along the axial direction from the oil storage assembly 1 to the atomization assembly 2. In this way, the two inclined surfaces can serve as guiding surfaces, which is beneficial to assembling the abutting portion 261 of the base 26 between the contact structure 292 of the air duct member 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 it is inclined outward along the axial direction from the atomization assembly 2 to the oil storage assembly 1. The lateral dimension of the space between the contact structure 292 of the air duct member 29 and the inner wall of the mounting groove 252 gradually decreases. In this way, it can also play a guiding role in the assembly of the abutting portion 261.

[0077] Furthermore, in some embodiments, an electronic atomization device includes a battery rod 20 and an atomizer 10, and the battery rod 20 is detachably connected to the atomizer 10.

[0078] In the embodiments of the present invention, the atomization assembly 2 and the oil storage assembly 1 of the atomizer are detachably connected, and the battery rod and the atomizer are also detachably connected. In this way, a three - section setting of the electronic atomization device can be realized, that is, the liquid storage part, the atomization part, and the power supply part of the electronic atomization device are divided into three parts, which can achieve separate storage and separate transportation, and can be replaced according to actual needs, so that the functional parts can be reused, saving energy and being environmentally friendly.

[0079] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0080] The above is the description of the technical solutions provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
