[0021] like Figure 1As shown, the smoking device based on circumferential heating of a long cigarette provided by this utility model includes a shell assembly, a heating assembly, a main support 19, a top cover assembly, and an electrical assembly. Compared with the traditional main support 19, the main support 19 of this application is designed with a left-right structure. A mounting slot for installing the heating assembly is designed on the left side of the main support 19, and a rectangular cuboid-shaped battery cell slot for installing the battery cell is opened in the middle of the right side. The corners of the battery cell slot are rounded, and the surface of the battery cell slot is a flat structure for fixing the main board. The assembled heating assembly is installed in the mounting slot on the main support 19, and the battery cell 20 is placed in the battery cell slot and fixed and locked to prevent it from slipping or vibrating. This is achieved by screws. The mainboard is fixed to the main bracket 19. The display screen is positioned on the mainboard using a screen bracket. The screen bracket is then fixed to the mainboard with screws to complete the assembly of the internal components of the smoking device. The assembled main bracket 19 is installed into the inner cavity of the housing assembly. The top cover assembly is connected to the housing assembly via a plug-in method, sealing the assembled main bracket 19 within the inner cavity of the housing assembly. The heating component and infrared plate 16 are connected to the mainboard via wires. The assembled smoking device has a rectangular structure with rounded upper and lower edges and a long elliptical cross-section. In this smoking device, the length of the heating element 11 is slightly less than the height of the housing assembly. This structural design is suitable for both long and short cigarettes. The air passage formed by the gap between the cigarette 26 and the heating element 11 allows air to enter from the bottom and provide effective oxygen content for heating the cigarette. Placing the air passage within the heat insulation layer effectively improves energy utilization.

[0022] In this application, the heating assembly includes an aerogel base 13, an aerogel sleeve 12, a cigarette holder 14, a cigarette holder bracket 15, a heating element 11, an infrared plate 16, and a silicone sleeve 17. The aerogel base 13 consists of an upper pad and a frustum disposed on the lower surface of the upper pad, with a through hole in its center. The aerogel sleeve 12 is vertically mounted on the aerogel base 13, and the centerline of the aerogel sleeve 12 and the centerline of the aerogel base 13 are both on the centerline of the through hole. The cigarette holder 14 is installed on the aerogel sleeve. Inside 12, the bottom protrusion passes through the through hole and is assembled into one piece. After the heating element 11 is installed and fixed in the cavity of the cigarette holder 14, the cigarette holder bracket 15 is inserted into the cigarette holder 14 so that the top of the heating element 11 is inserted into the cigarette holder bracket 15, thus completing the positioning and fixing of the heating element 11 in the cavity of the cigarette holder 14. The silicone sleeve 17 is placed on the cigarette holder bracket 15, and the two infrared plates 16 are installed on the silicone sleeve 17 respectively, so that the two infrared plates 16 are arranged symmetrically on the silicone sleeve 17. The heating element 11 in the heating assembly consists of a heat-conducting pipe 111, a first heating film 112, and a second heating film 113. The first heating film 112 and the second heating film 113 are placed on the outer surface of the heat-conducting pipe 111 by means of attachment or printing, respectively, with the first end of the first heating film 112 having a first solder pad for connecting wires, and the first end of the second heating film 113 having a second solder pad for connecting wires. A third solder pad is shared at the connection between the second end of the first heating film 112 and the second end of the second heating film 113. After being laid out, the first heating film 112 and the second heating film 113 both have a square wave structure, with different heights of the two square waves. The height of the square wave formed by the second heating film 113 is between 1.5 and 2 times that of the square wave formed by the first heating film 112. The inserted cigarette stick 26 is secured using a silicone sleeve 17. Aerogel is used for insulation within this assembly, allowing it to operate unaffected for extended periods at 300 degrees Celsius. The cigarette holder 14 and holder bracket 15, used to secure the heating element, are both made of high-temperature resistant PEEK material. An infrared plate 16 identifies whether a cigarette stick 26 is inserted into the heating element. The segmented heating design of the heating element 11 allows for heating of different positions of the cigarette stick 26, improving energy efficiency. The heating film on the heating element 11 has an upper and lower structure, allowing for flexible software control of the specific parts requiring heating. This flexible control of the heating location facilitates adjustment of smoke volume and flavor, and allows for the use of more cigarette types. The software-controlled segmented heating is a mature technology in electronic cigarette devices and will not be elaborated upon further here.

[0023] The top cover assembly includes an upper cover 15, a dust cover bracket 22, a magnet bracket 23, a dust cover, several magnets 24, and several screws. The magnets 24 are respectively installed in magnet slots on the dust cover bracket 22 and magnet slots on the magnet bracket 23. The magnets are disc-shaped, and the corresponding slots are circular. The dust cover bracket 22 is fixedly mounted on the upper cover 25 with screws. The dust cover is screwed onto the magnet bracket. The magnet bracket 23 is slidably mounted on the dust cover bracket 22, so that when the dust cover is moved, the magnet bracket 23 moves along with the dust cover on the dust cover bracket 22. This top cover assembly technology is very mature and will not be described in detail in this application.

[0024] The electrical components include a battery cell 20, a main board, a display screen, a vibration motor, a screen bracket, and a charging interface. The battery cell 20 is installed in a battery cell slot on the main bracket. The main board is fixed to the main bracket with screws and is electrically connected to the battery cell. The charging interface allows mains power to be supplied to the battery cell, or the charge in the battery cell 20 to power the main board. The charging interface is soldered onto the main board, and its output is connected to the charging and discharging circuit on the main board. The display screen is fixed to a predetermined position on the main board via the screen bracket and is communicatively connected to the main board. The main board is communicatively connected to the heating element and the infrared plate. The vibration motor is located on the main bracket, below the heating assembly, and is communicatively connected to the main board. Given the highly mature technology of electrical components and control software in electronic cigarette devices, this application only changes the shape and size of the battery cell without improving other technologies; therefore, the electrical structure will not be described in detail.

[0025] The housing assembly includes an outer shell 18, a lens, and buttons. The lens is mounted on the outer shell 18, and the buttons are movably mounted on the lens. Maintenance and repair are convenient, and replacement is an option. This structure is a mature technology and will not be described in detail here.

[0026] Insert the cigarette stick 26 into the cavity of the heating element and press and hold the button to start the device. The heating element will start working to heat the cigarette stick, and the current working status of the device will be displayed on the screen. As time goes on, the device will gradually reach the smoking state. At this time, the motor will vibrate to prompt the user to smoke. When smoking, air will pass through the gap between the cigarette stick and the inner wall of the heating element, entering from the bottom of the cigarette stick and then rising into the inlet. This air passage design allows the air to enter and gradually heat up. The air passes through the cigarette stick and is reused, making energy circulation more efficient and improving utilization. When the cigarette stick is finished heating, the motor will vibrate again, and the screen will display the corresponding information.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
