All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0029] See also Figures 1 to 4 An embodiment of the present invention provides an atomization device, which includes a nozzle assembly 100 and an atomization assembly 200. The nozzle assembly 100 includes a housing 10, an oil guide assembly 30, and a cover 40. The housing 10 has an oil storage chamber 13 and opposing first and second ends. The first end is formed with a nozzle 20, and the second end has a first opening 11 and a second opening 12. The first opening 11 is in communication with the nozzle 20, and the second opening 12 is in communication with the oil storage chamber 13. The oil guide assembly 30 is fixedly disposed in the second end of the housing 10 and seals the second opening 12. The cover 40 is detachably sealed at the second end of the housing 10 and has a plug 41 that is sealedly connected to the first opening 11. It should be understood that the passage between the nozzle 20 and the first opening 11 is an airflow passage.

[0030] Combine Figure 3 and Figure 4 As shown, the atomization device of this embodiment is achieved by separating the nozzle assembly 100 and the atomization assembly 200 and setting the oil storage chamber 13 in the shell 10 of the nozzle assembly 100. When transporting and storing, the nozzle assembly 100 is sealed on the second end of the shell 10 through the cover 40, so that the nozzle assembly 100 forms a separate whole, thereby avoiding the problem of oil leakage into the atomization assembly 200 during transportation and storage of the atomization device, and the first opening 11 is sealed and blocked by the plug 41 provided on the cover 40, thereby avoiding oil from seeping into the first opening 11 and contaminating the air flow channel, thereby ensuring the user's smoking taste during normal use.

[0031] The outer wall of the second end of the housing 10 is provided with an external thread 14, and the inner wall of the cover 40 is provided with a first internal thread 42 that cooperates with the external thread 14. The cover 40 is detachably covered on the second end of the housing 10 through the cooperation of the first internal thread 42 and the external thread 14. Figure 5 and Figure 6As shown, the atomizer assembly 200 includes a connecting seat 50 and an atomizer core 60. One end of the connecting seat 50 has a receiving cavity 51. The atomizer core 60 is arranged in the receiving cavity 51. The side wall of the receiving cavity 51 is provided with a second internal thread 52. When the nozzle assembly 100 needs to be used, the cover 40 can be unscrewed from the shell 10, and then the connecting seat 50 and the shell are threadedly connected and fixed through the second internal thread 52 and the second end external thread 14 of the shell 10. When the connecting seat 50 is screwed into the shell 10, the atomizer core 60 abuts against the oil guide assembly 30 and is connected to the first opening 11.

[0032] That is to say, the shell 10 of the nozzle assembly 100 in the atomizing device of this embodiment can be selectively sealed and connected with the cover 40 or the atomizing assembly 200. When in the transportation or storage state, the shell 10 is sealed and connected with the cover 40 to avoid oil leakage. When suction is required, the cover 40 is unscrewed from the shell 10 and then the shell 10 is assembled on the atomizing assembly 200.

[0033] The atomizer core 60 in this embodiment is a separate structure from the connecting base 50, that is, the atomizer core 60 can be replaced separately. When the connecting base 50 is assembled and fixed to the housing 10, the two ends of the atomizer core 60 respectively abut between the bottom wall of the connecting base 50 and the oil guide assembly 30.

[0034] Specifically, combined Figure 7 As shown, the atomizer core 60 includes an atomizer seat 61 having an atomizer chamber 611, a cylindrical electrode 62 disposed in the atomizer chamber 611, and a heating element 63 covering the atomizer chamber 611 and electrically connected to the electrode 62. When the connecting seat 50 is screwed into the shell 10, the heating element 63 abuts against the oil guide assembly 30, and the cylindrical electrode 62 is connected to the first opening 11.

[0035] In this way, the atomization device of this embodiment can be connected to the battery rod to form a complete electronic cigarette, so that the battery rod supplies power to the atomization core 60, and the heating element 63 can adopt a heating net, which is in contact with the oil guide component 30. After power is turned on and heating is generated, the tobacco liquid on the contact surface between the heating element 63 and the oil guide component 30 can be heated and atomized. The generated aerosol enters the first opening 11 through the atomization chamber 611 and is output from the suction nozzle 20 for the user to inhale.

[0036] It should be noted that the connector 50 in this embodiment has a connecting portion 54 at one end away from the atomizer core 60. The peripheral wall of the connecting portion 54 is provided with a threaded structure that can be connected to the battery rod, and a conductive contact 55 is provided inside the connecting portion 54. One end of the conductive contact 55 is electrically connected to the electrode 62 of the atomizer core 60, and the other end extends through the connecting portion 54. When the connector 50 is threadedly connected to the battery rod, the internal circuit of the battery rod is electrically connected to the other end of the conductive contact 55, thereby achieving electrical connection between the battery rod and the atomizer core 60. Of course, in other embodiments, the connector 50 can also be configured as an integral structure with the battery rod, and this is not limited to this.

[0037] Furthermore, the side wall of the connecting base 50 defines a first air inlet 53 that communicates with the receiving chamber 51 and the outside world. The side wall of the atomizing base 61 defines a second air inlet 611 that communicates with the receiving chamber 51 and the atomizing chamber 611. The side wall of the electrode 62 defines a third air inlet 621 that communicates with the atomizing chamber 611 and the first opening 11. When a user inhales, outside air sequentially enters the atomizing chamber 611 through the first air inlet 53 and the second air inlet 611, mixes with the generated aerosol, and then enters the first opening 11 through the third air inlet 621. Finally, it is inhaled by the user through the mouthpiece 20.

[0038] In one embodiment, in order to facilitate the replacement of the suction nozzle 20, such as replacing a suction nozzle 20 with a different aperture, the shell 10 and the suction nozzle 20 in this embodiment are a split structure, and the first end of the shell 10 has a socket hole 15, and the bottom of the socket hole 15 extends along the axial direction of the shell 10 toward the second end to form a connecting tube 16 passing through the oil storage chamber 13, and the end of the connecting tube 16 forms a first opening 11; one end of the suction nozzle 20 has a socket part 21, and the socket part 21 is assembled in the socket hole 15 by plugging, and is connected with the first opening 11 through the connecting tube 16.

[0039] That is to say, the central through hole of the connecting tube 16 serves as the air flow channel of the entire atomizing device, and the aerosol generated by the atomizing core 60 passes through the air flow channel and is inhaled by the user through the mouthpiece 20; preferably, the shell 10 is roughly a conical cylindrical structure, and the central axis of the connecting tube 16 is on the same straight line as the central axis of the shell 10.

[0040] Furthermore, an annular groove 22 is formed on the peripheral wall of the sleeve portion 21 of the suction nozzle 20. A sealing ring is sleeved in the annular groove 22, and the sealing ring is held between the sleeve portion 21 and the inner wall of the sleeve hole 15. This ensures a sealed connection between the connecting tube 16 and the suction nozzle 20, ensuring a strong suction force when the user draws.

[0041] In another embodiment, the oil guide assembly 30 of this embodiment includes a fixing member 31, an oil suction member 32, an oil guide member 33 and a connecting sleeve 34. The fixing member 31, the oil suction member 32 and the oil guide member 33 are all annular plate-shaped bodies adapted to the second opening 12. The fixing member 31 is sleeved on the end of the connecting pipe 16. An annular stopper 341 is protruding from one end of the connecting sleeve 34, and the other end passes through the oil guide member 33, the oil suction member 32 and the fixing member 31 in sequence and is connected to the end of the connecting pipe 16. The annular stopper 341 fixes the fixing member 31, the oil suction member 32 and the oil guide member 33 to the end of the connecting pipe 16.

[0042] Among them, the fixing part 31 is made of a hard material and is evenly provided with a plurality of oil holes 311; it should be understood that when the atomizer assembly 200 is assembled with the shell 10, the heating element 63 of the atomizer core 60 is in close contact with the side of the oil guide part 33 away from the oil suction part 32, thereby clamping the oil suction part 32 and the oil guide part 33 between the heating element 63 and the fixing part 31. Preferably, in order to further position the oil suction part 32 and the oil guide part 33 during transportation and storage, a pressure ring 43 can also be provided in the cover 40 of the nozzle assembly 100 in this embodiment. The size of the pressure ring 43 is adapted to the oil suction part 32 and the oil guide part 33. When the cover 40 is closed on the shell 10, the pressure ring 43 is pressed between the oil guide part 33 and the cover 40.

[0043] The oil-absorbing member 32 and the oil-guiding member 33 can be made of oil-absorbing cotton or microporous ceramics. The tobacco oil in the oil storage chamber 13 enters the oil-absorbing member 32 and the oil-guiding member 33 through the oil hole 311 on the fixing member 31, so that after the heating member 63 is energized and heated, the tobacco oil on the contact surface between the oil-guiding member 33 and the heating member 63 is heated and atomized, thereby generating an aerosol.

[0044] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0045] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
