When the path of the vapor output channel 40 is long, air carrying the aerosol in the vaporization cavity 54 can be fully mixed in the vapor output channel 40, to improve mixing uniformity of the aerosol and the air, so that uniformity of mixed gas of the aerosol flowing out from the air outlet 11 and the air is high.

In this embodiment of this application, as shown in FIG. 2, the width L of the housing 10 is greater than a thickness H of the housing 10. The liquid substrate stored in the liquid storage cavity 13 is an e-liquid.

As shown in FIG. 2, FIG. 5, and FIG. 6, in this embodiment of this application, the vapor output channel 40 further includes a longitudinal channel part 44 extending in the longitudinal direction D1 of the housing 10. Specifically, the longitudinal channel part 44 includes a third channel part 441 and a fourth channel part 442, where the third channel part 441 is in airflow communication between the first channel part 41 and the vaporization cavity 54; and the fourth channel part 442 is in airflow communication between the first channel part 41 and the vaporization cavity 54. In this way, the vapor output channel 40 in this embodiment of this application forms double channels, and the vapor output channel 40 is in a shape of a broken line to lengthen the path of the vapor output channel 40.

The porous body 52 in this embodiment of this application includes porous ceramic. The porous body 52 is in fluid communication with the liquid storage cavity 13, so that the porous body 52 can adsorb and store the liquid substrate and transport the liquid substrate onto the heating element 53. The heating element 53 heats and vaporizes the liquid substrate that is adsorbed and stored by the porous body 52, so that the aerosol generated by heating is formed in the vaporization cavity 54. In another embodiment, a material of the porous body 52 may alternatively be another type of porous and high-temperature resistant material. In this embodiment of this application, the heating element 53 is a heating wire.

In an embodiment of this application, the support frame 30 includes a first part 31 and a second part 32 facing away from each other in the longitudinal direction D1, where the liquid storage cavity 13 is defined between the first part 31 and the housing 10, and the second part 32 provides the porous body 52 with support and holding; and the vapor output channel 40 includes a hollow cavity 43 formed between the first part 31 and the second part 32.

In this embodiment of this application, the hollow cavity 43 is internally provided with a separating part 33 extending between the first part 31 and the second part 32, and the separating part 33 separates the hollow cavity 43 to form the first channel part 41 and the second channel part 42. As shown in FIG. 6, a dashed line with an arrow in the figure indicates a path through which gas flows. In this embodiment of this application, the separating part 33 is arranged to separate the hollow cavity 43 into two channel parts, so that the mixed gas of the vaporized aerosol and the air circulates through the two channels, and finally circulates to the air outlet 11 and is discharged.

In this embodiment of this application, still as shown in FIG. 5 and FIG. 6, the second part 32 has an airflow guiding surface 321 opposite to the first part 31, and the airflow guiding surface 321 is constructed into a sloping arrangement. Specifically, in this embodiment of this application, the airflow guiding surface 321 is arranged as an arc surface, and the arc surface is curved toward a side of the porous body 52 and is configured to guide the mixed gas of the aerosol flowing out from the vaporization cavity 54 and the air to circulate toward the air outlet 11. In another embodiment, the airflow guiding surface 321 may alternatively be arranged as a sloping plane, making it convenient to guide an airflow to flow out toward the air outlet 11.

In an embodiment of this application, as shown in FIG. 4 and FIG. 5, a first end of the first part 31 is connected to the second part 32, and a second end is connected to the separating part 33; and a smoke outlet hole 311 is formed between the first end and the second end of the first part 31, and the smoke outlet hole 311 is in communication with the air outlet 11. In this embodiment of this application, two ends of the first part 31 in the direction of the width L (referring to FIG. 2) of the housing 10 are respectively the first end and the second end. In this embodiment of this application, the first end of the first part 31 is connected to the second part 32, the second end of the first part 31 is connected to the separating part 33, a part between the first end and the second end of the first part 31 and the second part 32 form the first channel part 41 and the second channel part 42, and the smoke outlet hole 311 is formed between the first end and the second end of the first part 31, so that the first channel part 41 and the second channel part 42 are in communication with the air outlet 11 through the smoke outlet hole 311 after converging.

In this embodiment of this application, a first liquid inlet hole 312 and a second liquid inlet hole 313 are formed on the support frame 30, where the first liquid inlet hole 312 provides a first liquid path between the liquid storage cavity 13 and the porous body 52, and the second liquid inlet hole 313 provides a second liquid path between the liquid storage cavity 13 and the porous body 52; and a pore size of the first liquid inlet hole 312 is greater than a pore size of the second liquid inlet hole 313. In another embodiment, the pore size of the second liquid inlet hole 313 may alternatively be greater than the pore size of the first liquid inlet hole 312.

Specifically, in this embodiment of this application, the first liquid inlet hole 312 is formed on the first end of the first part 31; and the second liquid inlet hole 313 is formed on the second end of the first part 31. In this embodiment of this application, two liquid inlet holes, namely, the first liquid inlet hole 312 and the second liquid inlet hole 313, are arranged, so that the first liquid inlet hole 312 and the second liquid inlet hole 313 are in communication with the liquid storage cavity 13 and the second part 32, and the liquid substrate stored in the liquid storage cavity 13 circulates onto the porous body 52 in the second part 32, making it convenient to form the aerosol by heating and vaporization of the heating element 53.

In this embodiment of this application, the pore size of the first liquid inlet hole 312 is greater than the pore size of the second liquid inlet hole 313. The pore size of the first liquid inlet hole 312 is bigger, so that the liquid substrate stored in the liquid storage cavity 13 can circulate to the second part 32 by passing through the first liquid inlet hole 312, and the air in the second part 32 can also circulate to the liquid storage cavity 13 by passing through the first liquid inlet hole 312. In this way, a pressure in the liquid storage cavity 13 and a pressure in the second part 32 can reach an equilibrium, and the liquid substrate in the liquid storage cavity 13 can circulate to the second part 32 by passing through the first liquid inlet hole 312 and the second liquid inlet hole 313. When the air in the second part 32 flows into the liquid storage cavity 13 by passing through the first liquid inlet hole 312, flowing of the liquid substrate in the liquid storage cavity 13 to the second part 32 by passing through the first liquid inlet hole 312 is affected to some extent. In this embodiment of this application, the pore size of the second liquid inlet hole 313 is smaller, and the liquid substrate stored in the liquid storage cavity 13 can be continually guided into the porous body 52 in the second part 32 by a capillary action. The aerosol generated by the heating element 53 cannot enter the second liquid inlet hole 313 due to a tension effect between the air and the aerosol, so that the liquid substrate stored in the liquid storage cavity 13 can be continually guided into the porous body 52, preventing the heating element 53 from dry heating caused by a failure of circulation of the liquid substrate in the liquid storage cavity 13 to the porous body 52 in the second part 32, and alleviating interruption of the aerosol discharged from the air outlet 11 that is caused by interruption of the aerosol. In this way, the liquid substrate in the liquid storage cavity 13 can be continually guided into the porous body 52 upon a pressure equilibrium to prevent a vaporization assembly from dry heating, so that the aerosol is continually discharged from the air outlet 11.

In this embodiment of this application, the second liquid inlet hole 313 penetrates through the separating part 33, so that the separating part 33 can separate the hollow cavity 43 between the first part 31 and the second part 32 to form the first channel part 41 and the second channel part 42, and meanwhile provide the second liquid path between the liquid storage cavity 13 and the porous body 52, and space can be saved.

In this embodiment of this application, the housing 10 includes a cylindrical body 15 and an end cap 20, where the end cap 20 includes a support arm 21 for supporting the support frame 30. When the aerosol formed in the vaporization cavity 54 contacts a side wall of the vapor output channel 40 upon circulating through the vapor output channel 40, the aerosol tends to be condensed to form an aerosol condensate. When the aerosol condensate is discharged into a user's mouth by passing through the air outlet 11, experience of the user is affected. Therefore, in this embodiment of this application, a first liquid storage groove 61 is arranged to store the aerosol condensate and alleviate outflow of the aerosol condensate through the air outlet 11.

The second liquid storage groove 62, in an aspect, has a function for storing the aerosol condensate, and in another aspect, has a function for transporting the aerosol condensate, making it convenient for the aerosol condensate in the vapor output channel 40 to be outputted through the second liquid storage groove 62. In this embodiment of this application, the second liquid storage groove 62 is arranged along a surface of the support frame 30, and the second liquid storage groove 62 is in a shape of a broken line. In another embodiment, the second liquid storage groove 62 may alternatively be in a shape of a curved line, or may be a combination of a shape of a curved line and a shape of a straight line.

Specifically, in this embodiment of this application, the second liquid storage groove 62 is in fluid communication with the first liquid storage groove 61, to transport the aerosol condensate in the second liquid storage groove 62 to the first liquid storage groove 61, making it convenient to transport the aerosol condensate in the vapor output channel 40 to the first liquid storage groove 61 for storage, thereby improving transport and storage effects of the aerosol condensate and reducing a probability and a volume of output of the aerosol condensate from the air outlet 11.

The battery cell 210 is configured to supply power. The controller 220 operably conducts a current between the battery cell 210 and the first electrical contact 230. In a preferred implementation shown in FIG. 7, the seal member 260 is constructed to extend in a cross-sectional direction of the power supply device 200, and is made of a flexible material, so as to prevent the liquid substrate seeping from the cartridge 100 to the receiving cavity 270 from flowing to the controller 220, the sensor 250, and other components inside the power supply device 200.

The battery cell 210 is configured to supply power. The controller 220 operably conducts a current between the battery cell 210 and the first electrical contact 230. The sensor 250 is configured to sense a suction airflow generated by the cartridge 100 upon suction, so that the controller 220 controls the battery cell 210 to output the current to the cartridge 100 according to a detection signal of the sensor 250.

In an embodiment of this application, a charging interface 240 is further arranged in the cavity 280 of the power supply device 200, and configured to charge the battery cell 210 after being connected to an external charging device.

The foregoing descriptions are merely implementations of this application but are not intended to limit the patent scope of this application. An equivalent structural or equivalent process alternation made by using the content of the specification and the accompanying drawings of this application for direct or indirect use in other relevant technical fields shall also be encompassed in the patent protection scope of this application.
