Referring to fig. 1, fig. 1 is a schematic electrical connection structure of a smoke generating device according to a first embodiment of the present application.
A first embodiment of the present application provides a smoke generating device 1000 comprising a power module 100, a drive module 200 and a heating module 300. Wherein the smoke generating device 1000 is a smoking aid accessory for a user to smoke a smoking article. In particular, the smoking article may be tobacco or a cigarette.
The power module 100 is electrically connected to the driving module 200. The driving module 200 is electrically connected to the heating module 300. The power module 100 is used to supply power to the driving module 200 and the heating module 300. The driving module 200 drives the heating module 300 to work, and the heating module 300 heats the air entering the heating module 300, and the hot air toasts the tobacco product, so that the tobacco product is atomized into smoke for the user to inhale.
Specifically, please refer to fig. 2 to 6. The heating module 300 of the first embodiment of the present application includes a base 10, a heat insulator 20, a bracket 30, a heating assembly 40, a fixing member 50, and a cover 60.
The base 10 is provided with a first opening 10A.
The heat insulator 20 has a cylindrical shape. The heat insulating member 20 is disposed on the base 10 and forms a receiving chamber M with the base 10.
The bracket 30 is disposed on the base 10 and is located in the receiving chamber M. The bracket 30 includes a support body 301 and first and second fixing portions 302 and 303 provided at both ends of the support body 301. The first fixing portion 302 is located at one end of the supporting body 301 near the base 10, and is inserted into the first opening 10A.
The heating assembly 40 is disposed on an end of the holder 30 remote from the base 10 and is located within the receiving chamber M. The heating assembly 40 includes a heat conductor 401. The heat conductor 401 is connected to the second fixing portion 303.
The fixing member 50 is disposed at an end of the heat conductor 401 remote from the base 10 and is located in the accommodating chamber M.
The portion of the housing M above the fixture 50 is used for the placement of the smoking article.
The cover 60 is disposed on the heat insulator 20. The cover 60 has a hollow structure with upper and lower openings. One end of the cover 60, which is close to the base 10, is fixedly connected with the heat insulating member 20.
It should be noted that, the heating module 300 of the present application may further include a housing disposed outside the heat insulating member 20, which is not described herein.
The heating module 300 of the first embodiment of the present application is provided with a first opening 10A on the base 10, the bracket 30 includes a supporting body 301, and a first fixing portion 302 and a second fixing portion 303 disposed at two ends of the supporting body 301, wherein the first fixing portion 302 is located at one end of the supporting body 301 near the base 10 and is inserted into the first opening 10A, and the second fixing portion 303 is connected with the heat conductor 401. The application facilitates the assembly of the whole heating module 300 and ensures that the connection between the bracket 30 and the base 10 is more stable by enabling the first fixing part 302 in the bracket 30 to be inserted into the first opening 10A on the base 10.
Please continue to refer to fig. 2-6. In the heating module 300 according to the first embodiment of the present application, the base 10 is provided with a plurality of air intake holes 10B, as shown in fig. 4. The air intake holes 10B are provided at intervals on the outer peripheral side of the first opening 10A. The air intake holes 10B are used for introducing outside air.
The bracket 30 is provided with a through hole 30A. The through hole 30A penetrates the first fixing portion 302, the supporting body 301, and the second fixing portion 303. The material of the bracket 30 may include a material such as zirconia, silica, or ceramic that is resistant to high temperatures and has a low thermal conductivity to reduce heat loss during conduction.
With continued reference to fig. 3, in the heating module 300 according to the first embodiment of the present application, an area of a surface of the first fixing portion 302 facing the base 10 is smaller than an end surface area of the supporting body 301. This setting is when guaranteeing that support 30 has good supporting role for have less area of contact between support 30 and the base 10, and then when heat in the heat conductor 401 is conducted to support 30 along the direction towards base 10, because area of contact between support 30 and the base 10 is less, and then can reduce the temperature of base 10, thereby improved the comfort when smoking set uses.
Accordingly, the area of the surface of the second fixing portion 303 that abuts against the heat conductor 401 is smaller than the end surface area of the support body 301. This arrangement allows a smaller contact area between the support 30 and the heat conductor 401, which in turn reduces the temperature of the support 30 itself to further reduce the temperature of the base 10.
In the present application, the supporting body 301 may have a cylindrical structure, but is not limited thereto. The areas of both end surfaces of the support body 301 are the same.
The heating assembly 40 includes a heat conductor 401 and a heat generating member 402. The heat generating member 402 includes a heat generating body 4021 and a pin 4022 connected to the heat generating body 4021.
The end of the heat conductor 401 facing the base 10 is provided with a second opening 401A. The second opening 401A is provided corresponding to the second fixing portion 303. The second fixing portion 303 abuts a portion of the heat conductor 401 located on the circumferential side of the second opening 401A.
In the above arrangement, since the second fixing portion 303 is abutted only against the portion of the heat conductor 401 located on the circumferential side of the second opening 401A, the convenience of assembling the heating module 300 can be further improved.
The heat conductor 401 is made of a material with high heat conductivity. The material of the heat conductor 401 may include a sintered body of a material such as aluminum oxide, zirconium oxide, or silicon nitride; and may also include metallic materials such as aluminum, copper, or iron. When the metal material is selected to prepare the heat conductor 401, an insulating treatment needs to be performed on the surface of the heat conductor 401 to prevent the heat generating element 402 from being short-circuited when the heat conductor 401 contacts with the heat generating element 402.
An accommodating space 401B is provided at an end of the heat conductor 401 facing the second fixing portion 303. The accommodating space 401B communicates with the second opening 401A and the first opening 10A. The heat generating body 4021 is provided in the accommodating space 401B and sealed with an inorganic adhesive such as ceramic adhesive or glass frit adhesive. Wherein the heating body 4021 is a heating wire.
A plurality of air guide grooves 401C are provided on the outer wall of the heat conductor 401. The air guide groove 401C extends from an end of the heat conductor 401 remote from the base 10 to an end near the base 10. The air intake hole 10B is used for communicating outside air with the air guide groove 401C. A chamber N is formed between the bracket 30 and the heat shield 20. The air inlet hole 10B, the chamber N and the air guide groove 401C form an air passage, and air is heated while passing through the air guide groove 401C in the air passage and enters into the space of the accommodating chamber M above the fixing member 50 to heat the smoking article.
The pins 4022 sequentially penetrate through the first opening 10A and the through hole 30A, and extend into the accommodating space 401B. Wherein an end of the pin 4022 remote from the base 10 is electrically connected to the driving module 200 (not shown).
In the heating module 300 according to the first embodiment of the present application, the support 30 further includes a heat insulation layer 304, and the heat insulation layer 304 is disposed on the wall of the through hole 30A, as shown in fig. 5. Because the insulating layer 304 has good heat insulation effect, the arrangement can reduce the probability of heat in the pins 4022 being conducted to the bracket 30 along the radial direction, thereby being beneficial to reducing the temperature of the bracket 30 so as to further reduce the temperature of the base 10.
