Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and description only, and is not intended to limit the application. In the present application, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used to generally refer to the upper and lower positions of the device in actual use or operation, and specifically the orientation of the drawing figures; while "inner" and "outer" are for the outline of the device.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram illustrating an explosion structure of a heating module 100 according to the present application; fig. 2 is a schematic cross-sectional view of a heating module 100 according to the present application. The heating module 100 provided by the embodiment of the application can be used for a smoke generating device. By smoke generating device is meant a smoking aid accessory for a user to smoke a smoking article.
The heating module 100 includes a bottom bracket 10, a first heating assembly 30, and an air duct 20. The bottom bracket 10 has a receiving chamber 10A. The bottom bracket 10 has oppositely disposed first and second ends 101, 102. The first heating assembly 30 is disposed at the first end 101 and extends into the receiving chamber 10A. Airway tube 20 is disposed at second end 102 and is partially disposed within receiving chamber 10A. The side wall of the air duct 20 near one end of the first heating assembly 30 is connected to the inner side wall of the bottom bracket 10. Wherein, at least one opening 200 is provided on the sidewall of the airway tube 20. The opening 200 is located at an end of the airway tube 20 proximate to the first heating assembly 300. Airway tube 20 is used to introduce gas into first heating assembly 30 through opening 200.
In the embodiment of the application, an air duct 20 is disposed in the heating module 100 to introduce air into the first heating element 30. Wherein, the opening 200 for guiding out the gas from the gas channel tube 20 is arranged on the side wall of the gas channel tube 20 near one end of the first heating component 30, so that the gas has a bending angle from the gas channel path of the gas channel tube 20 flowing to the first heating component 30, the gas in the first heating component 30 can be prevented from flowing backwards to the gas channel tube 20, the heat loss is effectively reduced, the cigarettes are uniformly heated, and the smoking experience of the cigarettes is improved while the power consumption is reduced.
In addition, the flowing gas entering the first heating element 30 may take away the smoke generated in the heating module 100, thereby affecting the temperature in the heating module 100. When the speed of the external air entering is high, the first heating component 30 cannot generate corresponding heat in time; when the external air enters slowly, a great amount of heat is accumulated in the first heating component 30, and the heat cannot be taken out in time, so that the temperature of smoke entering the oral cavity is too high, and the oral cavity is scalded.
In view of the above, the embodiment of the present application provides the opening 200 for guiding the gas from the gas channel tube 20 on the side wall of the gas channel tube 20 near the end of the first heating element 30, so that the gas channel path from the gas channel tube 20 to the first heating element 30 has a bending angle, and the gas flow rate can be reduced. At the same time, the flux of gas may be further defined through opening 200, thereby maintaining stability of the amount of gas flowing from airway tube 20 to first heating assembly 30.
With continued reference to fig. 1 and 2, in an embodiment of the application, the heating module 100 includes a bottom bracket 10, an air duct 20, a first heating element 30, a first connecting member 40, a receiving cavity 50, a housing 60, a second connecting member 70, and a cover 80. The first heating assembly 30 includes a first support 31, a second support 32, and a heating member 33.
Wherein, the bottom bracket 10 has a receiving cavity 10A. The bottom bracket 10 has oppositely disposed first and second ends 101, 102. The support 20 is disposed at the second end 102 and extends partially into the receiving chamber 10A. The first heating assembly 30 is disposed at the first end 101. The receiving chamber 50 is disposed at a side of the first heating assembly 30 remote from the bottom bracket 10, and is connected to the first heating assembly 30 through a connection member 40. The housing 60 is disposed on the bottom bracket 10 and covers the first heating assembly 30, the connection member 40, and the receiving chamber 50. The cover 80 is disposed at a side of the housing 60 away from the bottom bracket 10, and the cover 80 is connected with the accommodating cavity 50 through the connection member 60.
Specifically, as shown in fig. 3, the bottom bracket 10 includes a bracket body 11, a mount 12, and a first annular wall 13. The holder body 11, the mount 12, and the first annular wall 13 are coaxially disposed and connected to each other. The accommodation chamber 10A penetrates the holder main body 11 and the mount 12. The mount 12 is provided on the holder main body 11. The first annular wall 13 is provided on a side of the mount 12 remote from the holder main body 11.

The inner side wall of the first annular wall 13 is provided with a plurality of first fixing portions 131 arranged at intervals.

The arrangement of the first fixing portion 131 and the second fixing portion 132 achieves point contact connection between the bottom bracket 10 and the first supporting member 31 and between the bottom bracket 10 and the housing 60, reduces a contact area, and further reduces heat conduction loss.
As shown in fig. 2 and 4, airway tube 20 is disposed at second end 102 of bottom bracket 10 and is partially disposed within receiving chamber 10A. The side wall of the air duct 20 near one end of the first heating assembly 30 is connected to the inner side wall of the bottom bracket 10. Wherein, at least one opening 200 is provided on the sidewall of the airway tube 20. The opening 200 is located at an end of the airway tube 20 proximate to the first heating assembly 300. Airway tube 20 is used to introduce gas into first heating assembly 30 through opening 200.
The shape of the opening 200 may be circular, square, triangular or trapezoidal, which is not limited in the present application. The number of the openings 200 may be one, two or more, and may be specifically designed according to actual needs, which is not specifically limited by the present application. The size of the opening 200 may also be designed according to the actual size of the airway tube 20.
In the embodiment of the present application, the inner passage 20A of the airway tube 20 is cylindrical. The number of openings 200 is two. Two openings 200 are oppositely disposed on the side wall of airway tube 20. The two oppositely disposed openings 20 can ensure the smoothness of the gas circulation, and ensure that sufficient gas is introduced into the first heating assembly 30 while avoiding the gas in the first heating assembly 30 flowing back to the internal channel 20A.
Optionally, in some embodiments, referring still to FIG. 4, airway tube 20 further includes an insulating layer 210. The insulation layer 210 is disposed on the inner sidewall of the airway tube 20. Specifically, the insulating layer 210 may completely cover the inner sidewall of the air duct pipe 20, and the insulating layer 210 may cover only the inner sidewall of the air duct pipe 20 near one end of the first heating assembly 30.
The heat insulating layer 210 may be a heat insulating film layer formed of a porous material such as glass fiber, aerogel or heat insulating cotton, a heat reflecting film layer formed of a metal material having heat reflection properties such as aluminum, gold, silver, nickel, or a film material capable of reflecting radiant heat energy such as a polyester or polyimide film coated with a metal material, and the structure and material of the heat insulating material are not particularly limited.
It will be appreciated that even if a small amount of gas flows back from the first heating element 30 to the air duct 20, the heat insulating layer 210 located on the inner side wall of the air duct 20 can perform a heat insulating function, so that heat dissipation carried by the flowing back gas is avoided, and the gas is led into the first heating element 30 again, thereby improving the heating efficiency of the first heating element 30.
Alternatively, in some embodiments, as shown in FIG. 5, the internal passageway 20A of airway tube 20 is "T" shaped. Specifically, airway tube 20 includes a first airway tube 201 and a second airway tube 202 that are in communication. The first airway tube 201 and the second airway tube 202 are coaxially disposed and connected to each other. The second air duct 202 is located at an end of the first air duct 201 adjacent to the first heating assembly 30. The pipe diameter of the second air passage pipe 202 is larger than that of the first air passage pipe 201. Wherein the opening 200 is provided on a side wall of the second airway tube 202.
Wherein, the internal channels of the first air passage pipe 201 and the second air passage pipe 202 are cylindrical.
The pipe diameter refers to the difference between the outer diameter and the inner diameter of the pipe when the pipe wall is relatively thin, and thus the average value of the outer diameter and the inner diameter of the pipe is referred to as the pipe diameter.
It can be seen that, since the pipe diameter of the second air passage pipe 202 is larger than that of the first air passage pipe 201, the length of the air passage path for the air flowing from the first heating assembly 30 to the air passage pipe 20 is extended while the bent air passage path is formed, the air in the first heating assembly 30 is further prevented from flowing backwards to the air passage pipe 20, and the heat loss is effectively reduced, so that the cigarettes can be uniformly heated, the power consumption is reduced, and the smoking experience of the cigarettes is improved.
Further, in the embodiment of the present application, the airway tube 20 is detachably connected to the bottom bracket 10. It will be appreciated that, due to the fluidity of the airflow, long-term use of the heating module 100 may cause residual tobacco tar to adhere to the inner sidewall of the air duct 20 and the end near the first heating element 30, which may generate an odor during the next sucking process, and affect the sucking experience of the user. According to the embodiment of the application, the air passage pipe 20 is detachably connected with the bottom bracket 10, so that when the smoke generating device is idle, the air passage pipe 20 can be taken out from the second end 102 of the bottom bracket 10 to clean tobacco tar remained on the air passage pipe 20, and the suction taste is prevented from being influenced.
Alternatively, in some embodiments, as shown in fig. 2, 4, and 6. Airway tube 20 includes a main airway tube 21.

And the outer diameter of the sealing ring 22 is adapted to the inner diameter of the bottom bracket 10. The airway tube 20 is attached to the inside wall of the bottom bracket 10 by a seal 22.
It will be appreciated that airway tube 20 may be piston-moved within housing chamber 10A by seal 22. That is, the airway tube 20 may be inserted into or withdrawn from the accommodating chamber 10A of the bottom bracket 10 by an external force.
Wherein the first flange 211 is annular. The second flange 212 is truncated cone-shaped. The outer diameter of the second flange 212 gradually increases toward the first flange 211. It will be appreciated that the seal ring 22 is fitted over the outer peripheral side of the main air passage pipe 21 from the second flange 212 to the first flange 211, and thus the second flange 212 in the form of a truncated cone is provided so that the seal ring 22 is fitted over the outer peripheral side of the main air passage pipe 21 more easily through the second flange 212.
Wherein, the pipe diameter of the part of the main air passage pipe 21 between the first flange 211 and the second flange 212 is smaller than that of other parts, and the arrangement further reduces the difficulty of sleeving the sealing ring 22.
The sealing ring 22 is made of a material with certain elasticity so as to realize the function of piston connection. The material of the seal ring 22 may be natural rubber, nitrile rubber, urethane rubber or styrene-butadiene rubber, which is not particularly limited in the present application.
