[0028] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0029] As Figures 1 to 4 shown, an embodiment of the present utility model provides an internal rotation type air heating airway device for a heated cigarette, including: a housing, a heating component 1, and an internal rotation type airway component 2. The heating component 1 and the internal rotation type airway component 2 are both arranged in the housing, and the heating component 1 is used for heating a non-combustible cigarette.

[0030] The internal rotation type airway component 2 includes a fixed ring sleeve 21, a first inclined plate 22, a second inclined plate 23, and a heating gas delivery channel 24. The first inclined plate 22 is arranged at the top of the housing and is inclined towards the bottom of the housing.

[0031] The first end of the first inclined plate 22 is connected to the first end of the fixed ring sleeve 21, the first end of the second inclined plate 23 is connected to the inner wall of the fixed ring sleeve 21, there is a spacing between the first end of the first inclined plate 22 and the first end of the second inclined plate 23, the second end of the first inclined plate 22 is connected to the second end of the second inclined plate 23, the heating gas delivery channel 24 is arranged on the inner wall of the fixed ring sleeve 21, the first end of the heating gas delivery channel 24 respectively penetrates through the first inclined plate 22 and the second inclined plate 23, and the heating gas delivery channel 24 is used for introducing the gas heated by the heating component 1 to the top of the fixed ring sleeve 21.

[0032] Specifically, the heating gas delivery channel 24 is inclined, and there is an angle between the heating gas delivery channel 24 and the vertical plane, and this angle is an acute angle. Thus, when the gas in the heating gas delivery channel 24 is discharged, it forms an upward rotating state, and thus can form an internal rotation type air flow to heat the non-combustible cigarette; and it makes the air flow more concentrated, and at the same time can generate internal rotation, improving the effective utilization rate of the heating gas.

[0033] During operation, the heating component 1 heats the air inside the housing. The heated gas at the center of the housing directly moves towards the top of the housing. The heated gas at the outer edge of the housing enters the heated gas delivery channel 24. Since the first inclined plate 22 is inclined towards the bottom of the housing, the heated gas in the heated gas delivery channel 24 is guided towards the center of the housing and forms an upward rotating state, so that all the heated gas is directed to the non-combustible cigarette, heating the non-combustible cigarette and improving the heating efficiency.

[0034] In the present utility model, the first inclined plate 22 is arranged at the top of the housing and is inclined towards the bottom of the housing; the first end of the first inclined plate 22 is connected to the first end of the fixed ring sleeve 21, the first end of the second inclined plate 23 is connected to the inner wall of the fixed ring sleeve 21, there is a spacing between the first end of the first inclined plate 22 and the first end of the second inclined plate 23, the second end of the first inclined plate 22 is connected to the second end of the second inclined plate 23, and the heated gas delivery channel 24 is arranged on the inner wall of the fixed ring sleeve 21. The first ends of the heated gas delivery channels 24 respectively penetrate through the first inclined plate 22 and the second inclined plate 23. During operation, the heating component 1 heats the air inside the housing. The heated gas at the center of the housing directly moves towards the top of the housing. The heated gas at the outer edge of the housing enters the heated gas delivery channel 24. Since the first inclined plate 22 is inclined towards the bottom of the housing, the heated gas in the heated gas delivery channel 24 is guided towards the center of the housing and forms an upward rotating state, so that all the heated gas is directed to the non-combustible cigarette, reducing heat loss, improving the stability of the heated gas transmission and the heating efficiency of the non-combustible cigarette.

[0035] In an embodiment of the internal rotation type air heating airway device for a heated cigarette of the present utility model, as Figure 2 shown, the second inclined plate 23 is inclined towards the top of the housing. The first inclined plate 22 and the second inclined plate 23 form a storage channel 25.

[0036] The first inclined plate 22 is provided with air guide holes 221, and the air guide holes 221 are arranged close to the inner edge of the first inclined plate 22.

[0037] Specifically, when the heated gas delivery channel 24 delivers the heated gas into the storage channel 25, the pressure in the storage channel 25 will gradually increase, and then the heated gas discharged from the air guide holes 221 forms an upward rotating state and accelerates towards the non-combustible cigarette.

[0038] In the present utility model, the second inclined plate 23 is inclined towards the top of the housing, and the first inclined plate 22 and the second inclined plate 23 form a storage channel 25, such that the first end of the heating gas delivery channel 24 penetrates through the second inclined plate 23 and communicates with the storage channel 25, and the air guide holes 221 are arranged close to the inner edge of the first inclined plate 22, thereby enabling the formation of an inwardly swirling air flow, thus improving the heating efficiency and the speed of air flow.

[0039] In an embodiment of the inwardly swirling air heating airway device for a heated cigarette of the present utility model, as Figures 1 to 4 shown, there are multiple air guide holes 221, and the multiple air guide holes 221 are evenly spaced along the circumferential direction of the first inclined plate 22, and the extension lines of the central axes of the multiple air guide holes 221 have an intersection point.

[0040] In the present utility model, by arranging the multiple air guide holes 221 evenly spaced along the circumferential direction of the first inclined plate 22 and making the extension lines of the central axes of the multiple air guide holes 221 have an intersection point, the air flow discharged from the air guide holes 221 is further made to flow entirely towards the non-combustible cigarette, further reducing heat loss, lowering energy consumption, and reducing the usage cost.

[0043] In an embodiment of the inwardly swirling air heating airway device for a heated cigarette of the present utility model, as Figure 1 shown, there is a communication hole 27 at the central positions of the first inclined plate 22 and the second inclined plate 23, and the communication hole 27 is used for inserting the non-combustible cigarette into the interior of the housing.

[0044] In the present utility model, by having the communication hole 27 at the central positions of the first inclined plate 22 and the second inclined plate 23, the non-combustible cigarette can be inserted into the interior of the housing, ensuring that the non-combustible cigarette can be heated by the heating gas.

The limit ring plate 28 is disposed at the second end of the fixed ring sleeve 21, and the limit ring plate 28 has a connection hole 29 which communicates with the second end of the heating gas delivery channel 24.

[0046] In the present utility model, by disposing the limit ring plate 28 at the second end of the fixed ring sleeve 21, and the limit ring plate 28 has a connection hole 29 which communicates with the second end of the heating gas delivery channel 24, as much heating gas as possible is made to move from the middle position of the housing towards the top of the housing through the limit ring plate 28, further improving the heating efficiency of the non-combustible cigarette.

[0047] In an embodiment of the heating cigarette inward-rotating air heating airway device of the present utility model, as Figures 1 to 4 shown, the heating assembly 1 includes a support frame 11, a graphite heat conductor 12, a heating wire 13 and a connection wire 14.

[0048] Specifically, a plurality of micropores 121 are provided on the graphite heat conductor 12 for allowing the air inside the housing to flow through. The graphite heat conductor 12 causes some heat to return. Air can enter the graphite heat conductor 12 from the bottom to form a rotating upward air flow, which helps to uniformly release the heating gas and form a concentrated upward air flow.

[0049] In the present utility model, by disposing the heating wire 13 inside the graphite heat conductor 12, the first end of the connection wire 14 is electrically connected to the heating wire 13, and the inner peripheral wall of the support frame 11 is connected to the outer peripheral wall of the graphite heat conductor 12. During use, the battery supplies power to the heating wire 13 through the connection wire 14 to cause the heating wire 13 to heat the graphite heat conductor 12, and the graphite heat conductor 12 heats the gas inside the housing, ensuring the heating efficiency of the graphite heat conductor 12 for the gas. By connecting the support frame 11 to the housing, the stability of the heating assembly 1 fixed inside the housing is effectively ensured.
