[0037] In the above-mentioned cigarette cartridge with an annular airway, a transparent oil cup 200 is arranged in the hollow space 101 of the transparent outer cup 100 to form an annular airway 001 between the inner wall of the transparent outer cup 100 and the outer wall of the transparent oil cup 200. A suction nozzle assembly 300 is arranged at the top of the transparent outer cup 200 and the smoke outlet 301 of the suction nozzle assembly 300 is connected to the annular airway 001. At the same time, a accommodating cavity 200 is arranged at the bottom of the transparent oil cup 200 and connected to the oil storage cavity 201. 2 is provided with an atomizer assembly 400, and a threaded sealing seat 500 received at the bottom of the hollow space 101 is fastened to the transparent oil cup 200 to seal the transparent oil cup 200. Furthermore, an air inlet cavity 501 is provided on the threaded sealing seat 500 and is connected to the annular airway 001. After the atomizer assembly 400 atomizes the liquid flowing out of the transparent oil cup 200 and the airflow flowing along the air inlet cavity toward the atomizer assembly 400 into smoke, the smoke can rush into the annular airway 001. The use of a hidden annular air duct 001 gives the cigarette cartridge a beautiful and fashionable appearance; the annular air duct 001, the air inlet cavity 501 and the smoke outlet duct 301 form the entire smoke duct, and the atomized smoke is dispersed into the annular air duct 001 through the air inlet cavity 501. When the annular air duct 001 slowly transports the smoke upward to the docking with the smoke outlet duct 301, the smoke is collected into the smoke outlet duct 301 of the suction nozzle assembly 300, avoiding choking and enhancing the user experience.

[0038] In one embodiment, the transparent oil cup 200 is an amorphous copolyester PCTG cylindrical oil cup, and the transparent outer cup 100 includes a glass cylindrical outer cup.

[0039] In order to realize the docking assembly of the transparent oil cup 200, the nozzle assembly 300 and the threaded sealing seat 500, refer to Figures 1 to 5 In one embodiment, the transparent oil cup 200 is provided with an upper lock buckle 21 and a lower lock tongue 22 at both axial ends, the nozzle assembly 300 is provided with an upper lock tongue 31 at one end away from the outlet of the smoke duct 301, and a lock buckle portion 502 is provided on the inner side wall of the air inlet cavity 501, wherein,

[0040] The upper locking tongue 31 is received at the top of the hollow space 101 and buckled into the upper locking buckle 21 , so that the nozzle assembly 300 is buckled with the transparent oil cup 200 .

[0041] In this embodiment, the upper locking tongue 31 is composed of a plurality of petal-shaped buckles in a circular array, and a plurality of corresponding buckle holes are provided on the upper locking buckle 21. The upper locking tongue 31 is buckled into the upper locking buckle 21 from top to bottom, and each petal-shaped buckle is correspondingly buckled in the corresponding buckle hole, so that the upper locking tongue 31 is buckled with the upper locking buckle 21, and the suction nozzle assembly 300 is buckled with the transparent oil cup 200.

[0042] The lower locking tongue 22 is buckled with the locking portion 502 , so that the transparent oil cup 200 is buckled with the threaded sealing seat 500 .

[0043] In this embodiment, an annular inner groove is formed on the inner side wall of the air inlet cavity 501, and the annular inner groove serves as the corresponding locking portion 502. The lower locking tongue 22 is also composed of a plurality of petal-shaped buckles in a circumferential array. The lower locking tongue 22 is inserted into the air inlet cavity 501 from top to bottom and the petal-shaped buckles are locked on the annular inner groove, thereby engaging the lower locking tongue 22 with the locking portion 502, thereby achieving a buckling connection between the transparent oil cup 200 and the threaded sealing seat 500.

[0044] It can be understood that such a setting adopts the locking tongue and locking buckle connection method to achieve rapid assembly and docking of the transparent oil cup 200, the suction nozzle assembly 300 and the threaded sealing seat 500, improves assembly efficiency, and ensures a stable connection.

[0045] In order to achieve the sealing connection between the nozzle assembly 300 and the threaded sealing seat 500 and the transparent outer cup 100, refer to Figures 1 to 5 In one embodiment, an O-ring 900 is provided on the outer circumference of the upper locking tongue 31 and the threaded sealing seat 500. The O-ring 900 is used to tightly fit the upper locking tongue 31 and the transparent outer cup 100 when the upper locking tongue 31 of the suction nozzle assembly 300 is accommodated at the top end of the hollow space 101, and to tightly fit the threaded sealing seat 500 and the transparent outer cup 100 when the threaded sealing seat 500 is accommodated at the bottom end of the hollow space 101.

[0046] In order to further achieve a sealed connection between the threaded sealing seat 500 and the transparent outer cup 100 , in one embodiment, the transparent outer cup 100 is further fixed to the threaded sealing seat 500 accommodated at the bottom of the hollow space 101 by UV glue.

[0047] In this embodiment, after the threaded sealing seat 500 is docked with the transparent oil cup 200, its top portion will come into contact with the bottom of the transparent outer cup 100. At this time, UV glue is applied to the bottom of the transparent outer cup 100 to achieve the fixed connection between the transparent outer cup 100 and the threaded sealing seat 500.

[0048] In order to achieve the connection between the annular air duct 001 and the smoke outlet duct 301, refer to Figures 2 to 5 In one embodiment, a silicone sealing plug 23 is further provided at the top of the oil storage chamber 201. One end of the silicone sealing plug 23 is embedded in the oil storage chamber 201, and the other end passes through the upper locking buckle 21 upward and extends into the smoke outlet 301. The silicone sealing plug 23 and the inner wall of the smoke outlet 301 are combined to form an annular smoke outlet 302. The annular smoke outlet 302 and the columnar smoke outlet 303 located at the upper part of the suction nozzle assembly 300 form the smoke outlet 301. A radially penetrating smoke return port 211 is also provided at a position opposite to the upper locking buckle 21 and the silicone sealing plug 23. The smoke return port 211 connects the annular airway 001 and the annular smoke outlet 302, so that the annular airway 001 and the smoke outlet 301 are connected.

[0049] To achieve airflow injection and smoke dispersion, refer to Figures 2 to 5 In one embodiment, the air inlet cavity 501 includes a hollow upper cavity 503 and a hollow lower cavity 504. The threaded sealing seat 500 is provided with an air inlet hole 505 along the radial direction of the circumferential side wall of the hollow lower cavity 504. The air inlet hole 505 is used to allow airflow to flow into the air inlet cavity 501. The locking portion 502 is provided in the hollow upper cavity 503. The lower locking tongue 22 is provided with a radially through dispersion port 221. When the lower locking tongue 22 is locked in the locking portion 502, the dispersion port 221 connects the annular airway 001 with the hollow upper cavity 503. The air inlet hole 505, the air inlet cavity 501 and the dispersion port 221 also form an I-shaped air inlet duct 506. The I-shaped air inlet duct 506 is used to transport external airflow to the atomization assembly 400, and to disperse the atomized smoke into the annular airway 001.

[0050] It can be understood that with such a configuration, by providing a radially through air inlet hole 505, the air flow is horizontally injected into the hollow lower cavity 504 along the air inlet hole 505, and then floats up along the hollow lower cavity 504 and the hollow upper cavity 503 to contact the atomization component 400 to generate smoke in the air inlet cavity 501. Afterwards, the atomized smoke is dispersed through the dispersion port 221 provided on the lower lock tongue 22, and then injected into the annular airway 001 to prevent the smoke from rising directly vertically to the cigarette holder and causing choking when smoking.

[0051] It should be noted that, in this embodiment, by forming the I-shaped air inlet 506, the smoke is dispersed to the annular air duct 001, and the flow rate of the smoke is also moderated to make the smoke softer and improve the user experience.

[0052] In order to achieve smoke atomization, refer to 2 to Figure 5 In one embodiment, the atomizer assembly 400 includes a ceramic silicone insert 41 and a ceramic heating wire 42. The ceramic silicone insert 41 is accommodated in the accommodating chamber 202. The ceramic silicone insert 41 is provided with a communicating oil guide hole 411 and a mounting groove 412. The oil guide hole 411 is connected to the oil storage chamber 201, and the ceramic heating wire 42 is installed in the mounting groove 412. The tobacco oil stored in the oil storage chamber 201 is distributed along the oil guide hole 411 to the ceramic heating wire 42. The ceramic heating wire 42 is used to heat the tobacco oil to atomize and generate tobacco gas.

[0053] In one embodiment, the threaded portion 507 of the threaded sealing seat 500 is further provided with a plunger hole 508 , in which an electrode 800 is housed and installed through an insulating ring 700 . The electrode 800 is used to energize the ceramic heating wire 42 .

[0054] In one embodiment, an oil-absorbing cotton 600 is further provided at the bottom of the air inlet cavity 501, and an air flow hole 61 is provided on the oil-absorbing cotton 600 for air flow and electrical wires to pass through, wherein the oil-absorbing cotton 600 is used to absorb the smoke oil that is not atomized and falls and / or the smoke oil generated and dripped by smoke condensation.

[0055] In this embodiment, when a smoker uses the cigarette cartridge of the embodiment of the present application, the airflow enters through the air inlet 505. After the airflow passes through the atomizer assembly 400, the smoke generated by the heat of the atomizer assembly 400 rushes to the annular airway 001 formed between the transparent oil cup 200 and the transparent outer cup 100. At this time, the annular airway 001 is filled with smoke, and then it is inhaled into the mouth through the nozzle assembly 300.

[0056] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
