All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram illustrating an exploded structure of a heating module 100 according to the present application; fig. 2 is a schematic cross-sectional structural view of the heating module 100 provided in the present application. The heating module 100 provided by the embodiment of the application can be used for a smoking device. By smoking 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 element 30, and an airway tube 20. The bottom bracket 10 has a receiving cavity 10A. The bottom bracket 10 has a first end 101 and a second end 102 disposed opposite. The first heating element 30 is disposed at the first end 101 and extends into the receiving cavity 10A. Airway tube 20 is disposed at second end 102 and partially disposed within receiving chamber 10A. The side wall of the airway tube 20 near one end of the first heating unit 30 is connected to the inner side wall of the bottom chassis 10. Wherein, the sidewall of the airway tube 20 is provided with at least one opening 200. The opening 200 is located at an end of the airway tube 20 near the first heating assembly 300. Airway tube 20 is used to direct gas into first heating assembly 30 through opening 200.

In the embodiment of the present invention, an air duct 20 is disposed in the heating module 100 to introduce air into the first heating element 30. Wherein, the opening 200 that the gas channel pipe 20 derived gas sets up on the lateral wall of the one end that the gas channel pipe 20 is close to first heating element 30 for gas has a bend angle from the gas channel route of the first heating element 30 of the gas channel pipe 20 flow direction, can prevent the gas refluence in the first heating element 30 to gas channel pipe 20, effectively reduces calorific loss, thereby makes the cigarette by the even heating, in the time of reducing the consumption, improves the experience of cigarette suction.

In addition, the flowing gas entering the first heating element 30 carries away the smoke generated in the heating module 100, thereby affecting the temperature in the heating module 100. When the entering speed of the external air is high, the first heating assembly 30 cannot generate corresponding heat in time; when the outside air enters slowly, a large amount of heat is accumulated in the first heating assembly 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.

To address the above problem, the opening 200 for guiding the gas out of the gas channel tube 20 is disposed on the sidewall of the end of the gas channel tube 20 close to the first heating assembly 30, so that the gas channel path from the gas channel tube 20 to the first heating assembly 30 has a bent angle, which can slow down the flow rate of the gas. At the same time, the flux of gas may be further limited by the openings 200, thereby maintaining stability of the amount of gas flowing from the airway tube 20 to the first heating assembly 30.

Referring to fig. 1 and 2, in an embodiment of the present invention, 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 member 31, a second support member 32, and a heating member 33.

The bottom bracket 10 has a receiving cavity 10A. The bottom bracket 10 has a first end 101 and a second end 102 disposed opposite. The support member 20 is disposed at the second end 102 and extends partially into the receiving cavity 10A. The first heating assembly 30 is disposed at the first end 101. The receiving cavity 50 is disposed on a side of the first heating assembly 30 away from the bottom bracket 10, and is connected to the first heating assembly 30 through the connecting member 40. The housing 60 is disposed on the bottom bracket 10 and covers the first heating assembly 30, the connecting member 40, and the receiving cavity 50. The cover 80 is disposed on a side of the casing 60 away from the bottom bracket 10, and the cover 80 is connected to the accommodating cavity 50 through the connecting member 60.

Specifically, as shown in fig. 3, the bottom bracket 10 includes a bracket main body 11, a mount 12, and a first annular wall 13. The holder main body 11, the mount table 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 table 12. The mount table 12 is provided on the stand main body 11. The first annular wall 13 is provided on a side of the mount table 12 remote from the holder main body 11.

The mount 12 is cylindrical. The mounting stage 12 is provided with a plurality of vias 12A for passing through traces (e.g., electrode pins, etc.) in the heating module 100. The inner side wall of the first annular wall 13 is provided with a plurality of first fixing portions 131 arranged at intervals. The outer side wall of the first annular wall 13 is provided with a plurality of second fixing portions 132 arranged at intervals. The arrangement of the first fixing portion 131 and the second fixing portion 132 realizes point contact connection between the bottom bracket 10 and the first support member 31 and between the bottom bracket 10 and the housing 60, and reduces a contact area, thereby reducing heat conduction loss.

As shown in fig. 2 and 4, the airway tube 20 is disposed at the second end 102 of the bottom bracket 10 and partially disposed within the receiving cavity 10A. The side wall of the airway tube 20 near one end of the first heating unit 30 is connected to the inner side wall of the bottom chassis 10. Wherein, the sidewall of the airway tube 20 is provided with at least one opening 200. The opening 200 is located at an end of the airway tube 20 near the first heating assembly 300. Airway tube 20 is used to direct 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 this application. The number of the openings 200 may be one, two or more, and may be designed according to practical requirements, which is not specifically limited in this application. The size of the opening 200 may also be designed according to the actual size of the airway tube 20.

In the present embodiment, the internal passage 20A of the airway tube 20 is cylindrical. The number of openings 200 is two. Two openings 200 are oppositely disposed on the sidewall of the airway tube 20. The two oppositely disposed openings 20 can ensure smooth air flow, and ensure sufficient air is introduced into the first heating assembly 30 while preventing the air in the first heating assembly 30 from flowing back to the internal passage 20A.

Optionally, in some embodiments, continuing to refer to fig. 4, the airway tube 20 further includes a thermal insulation layer 210. The insulation layer 210 is provided on the inner sidewall of the airway tube 20. Specifically, the insulation layer 210 may completely cover the inner sidewall of the air passage pipe 20, or the insulation layer 210 may cover only the inner sidewall of the end of the air passage pipe 20 near the first heating assembly 30.

The heat insulation layer 210 may be a heat insulation film layer formed of porous materials such as glass fiber, aerogel or heat insulation cotton, or a heat reflection film layer formed of metal materials having heat reflection performance such as aluminum, gold, silver, and nickel, or a film material capable of reflecting radiant heat energy such as a polyester or polyimide film plated with metal materials, and the structure and the material of the heat insulation material are not specifically limited in the present application.

It can be understood that even if a small amount of gas flows back from the first heating element 30 to the air channel tube 20, the heat insulation layer 210 located on the inner side wall of the air channel tube 20 can also perform the heat insulation function, so as to prevent the heat carried by the flowing back gas from dissipating, so that the gas can be re-introduced into the first heating element 30, thereby improving the heating efficiency of the first heating element 30.

Alternatively, in some embodiments, as shown in FIG. 5, the internal passage 20A of the airway tube 20 is "T" shaped. Specifically, the air passage pipe 20 includes a first air passage pipe 201 and a second air passage pipe 202 that communicate with each other. The first air passage pipe 201 and the second air passage pipe 202 are coaxially disposed and connected to each other. The second air passage pipe 202 is located at one end of the first air passage pipe 201 near the first heating assembly 30. The pipe diameter of the second airway tube 202 is greater than the pipe diameter of the first airway tube 201. Wherein the opening 200 is provided on a side wall of the second airway tube 202.

The internal passages of the first air passage pipe 201 and the second air passage pipe 202 are cylindrical.

The pipe diameter means that the difference between the outer diameter of the pipe and the inner diameter of the pipe is almost the same when the pipe wall is thin, and the average value of the outer diameter of the pipe and the inner diameter of the pipe is taken as the pipe diameter.

It can know, because the pipe diameter of second air flue pipe 202 is greater than the pipe diameter of first air flue pipe 201, when forming the air flue route of buckling, extended the length that gas flowed to the air flue route of air flue pipe 20 from first heating element 30, further prevented the gas refluence in the first heating element 30 to air flue pipe 20, effectively reduced calorific loss to make the cigarette can by the even heating, when reducing the consumption, improve the experience of cigarette suction.

Further, in the present embodiment, the airway tube 20 is detachably connected to the bottom bracket 10. It will be appreciated that, due to the fluidity of the airflow, prolonged use of the heating module 100 may result in residual soot being attached to the inner side wall of the airway tube 20 and the end near the first heating element 30, which may cause odor during the next smoking process, thereby affecting the smoking experience of the user. The connection can be dismantled through setting up gas channel pipe 20 and bottom support 10 to this application embodiment, when smoke generating device was idle, can take out gas channel pipe 20 from the second end 102 of bottom support 10 to wash the tobacco tar of remaining on gas channel pipe 20, avoid influencing the suction taste.

Optionally, in some embodiments, as shown in fig. 2, 4, and 6. Airway tube 20 includes a main airway tube 21. The main airway tube 21 has a first flange 211 and a second flange 212 on the side wall near the end of the first heating element 30, and the second flange 212 is located between the first flange 211 and the opening 200.

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 inner wall of the bottom bracket 10 by a gasket 22.

It will be appreciated that the airway tube 20 can be piston-moved within the receiving chamber 10A by means of the sealing ring 22. That is, the airway tube 20 can be inserted into or withdrawn from the receiving cavity 10A of the bottom bracket 10 by an external force.

Wherein, the first flange 211 is ring-shaped. The second flange 212 is circular truncated cone-shaped. The outer diameter of the second flange 212 gradually increases toward the first flange 211. It is understood that the seal ring 22 is fitted on the outer peripheral side of the main air passage pipe 21 from the second flange 212 toward the first flange 211, and therefore the circular truncated cone-shaped second flange 212 is provided so that the seal ring 22 is more easily fitted on the outer peripheral side of the main air passage pipe 21 through the second flange 212.

The pipe diameter of the main airway tube 21 between the first flange 211 and the second flange 212 is smaller than the pipe diameters of other parts, and the arrangement further reduces the difficulty of sleeving the sealing ring 22.

Wherein, the sealing ring 22 is made of a material with certain elasticity to realize the function of piston connection. The material of the sealing ring 22 may be natural rubber, nitrile rubber, polyurethane rubber, or styrene-butadiene rubber, which is not specifically limited in this application.
