Description

Technical Field

[0001] This utility model relates to the field of heated cigarette technology, specifically to an electric heating device for heated cigarettes with a built-in temperature measuring element. Background Technology

[0002] Heated cigarettes, also known as heated non-combustible cigarettes or low-temperature cigarettes, are a new type of tobacco product that releases nicotine and other components by heating tobacco instead of burning it. This is achieved by heating the tobacco to a high temperature of approximately 300-350°C, causing it to release nicotine-containing aerosols without producing the smoke or ash found in traditional cigarettes. The main methods used include resistance heating, electromagnetic heating, and infrared heating. The existing technology is authorized by publication number CN 113749299. B proposes an electromagnetic heating cigarette device and its heating method. Within the heating chamber, multiple temperature zones are arranged sequentially and continuously according to temperature using an induction coil or induction heating element. These temperature zones move in a step-by-step manner within the heating chamber, causing the tobacco medium to be heated progressively. The initial position of the induction coil or induction heating element is located near the smoke inlet, with higher temperature zones positioned closer to the smoke inlet and lower temperature zones closer to the air inlet. During use, the cigarette needs to be inserted into the heating chamber. To facilitate this insertion, the diameter of the heating chamber is larger than the diameter of the cigarette, resulting in insufficient contact between the heating element and the cigarette during heating, affecting heat conduction. Furthermore, the built-in temperature sensor primarily determines the cigarette's heating temperature by detecting the temperature of the heating element, impacting the accuracy of the heating device's temperature assessment.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This embodiment provides a technical solution: an electric heating device for heated cigarettes with a built-in temperature measuring element, including an electric heating shell 1, which provides space for the electric heating component. The electric heating shell 1 is equipped with a battery 2 and a temperature sensor 4. The battery 2 is located on the left inner wall of the electric heating shell 1 and provides power for the operation of the whole device. The built-in temperature sensor 4 is used to detect the electric heating temperature, which facilitates the control of the heating temperature. A microcontroller 3 is located on the left side of the electric heating shell 1 to control the start and stop of the whole device. The input end of the microcontroller 3 is electrically connected to the output end of the battery 2, and the output end of the temperature sensor 4 is electrically connected to the input end of the microcontroller 3. A telescopic rod 7 is located on the right end of the inner wall of the electric heating shell 1. The temperature sensor 4 is located at the telescopic end of the telescopic rod 7, so that the temperature sensor 4 moves with the electric heating component to ensure normal temperature detection. A silicone mouthpiece 8 is sleeved on the outer arc surface of the air outlet of the electric heating shell 1 to facilitate the inhalation of the smoke generated by the heated cigarette. It also includes a heating mechanism 5.

[0020] Heating mechanism 5 includes arc-shaped heating plates 51, which are horizontally slidably connected to the inside of the electric heating housing 1. Each arc-shaped heating plate 51 is a heating element made by printing metal circuits on ceramic. The three arc-shaped heating plates 51 are arranged in a ring around the central axis of the cigarette insertion port of the electric heating housing 1. The detection end of the temperature sensor 4 is fixedly connected to the outer arc surface of the right-side arc-shaped heating plate 51. The input ends of the arc-shaped heating plates 51 are all electrically connected to the output end of the microcontroller 3. During use, the relative separation of the three arc-shaped heating plates 51 provides space for the insertion of heated cigarettes, making insertion easier. After insertion, the arc-shaped heating plates 51 return to their original position and contact the outer arc surface of the heated cigarette. To ensure more uniform heat distribution and more accurate heat transfer, the heating mechanism 5 also includes a support cylinder 52, guide columns 54, and a second return spring 55. The support cylinders 52 are respectively disposed on the inner wall of the electric heating shell 1. Guide columns 54 are horizontally slidably connected inside each support cylinder 52. The ends of the guide columns 54 are fixedly connected to the outer arc surface of adjacent arc-shaped heating plates 51. A second return spring 55 is provided between the limiting plate of the guide column 54 and the inner wall of the support cylinder 52. The second return spring 55 is movably sleeved on the outer arc surface of the guide column 54. During the movement of the arc-shaped heating plate 51, the guide column 54 slides within the support cylinder 52, providing guidance and support for the movement of the arc-shaped heating plate 51. Simultaneously, the second return spring 55 extends and retracts, utilizing its elasticity to support the arc-shaped heating plate... The automatic reset of 51 is powered by a top plate 56, a top ring 57, a connecting plate 58, and a pressing post 59. The top plate 56 is respectively disposed on the outer arc surface of the arc-shaped heating plate 51. The top rings 57 are respectively vertically slidably connected to the inside of the electric heating housing 1. The conical arc surface of the top ring 57 is fitted with the vertical plate of the top plate 56. A connecting plate 58 is provided between the left ends of the two top rings 57. The upper surface of the connecting plate 58 is provided with a pressing post 59. The pressing post 59 extends out of the inside of the electric heating housing 1. The pressing post 59 pushes the connecting plate 58 down, and the connecting plate 58 drives the two top rings 57 down. The conical arc surface of the top ring 57 applies force to the vertical plate of the top plate 56, pushing the arc-shaped heating plate 51 to move away from the center of the cigarette inlet of the electric heating housing 1. The horizontal movement of the heating plate 51 provides power. During use, the outer arc surface of the top ring 57 contacts the inner arc surface of the electric heating housing 1, restricting the rightward movement of the top ring 57. The connecting plate 58 fits against the outer casing of the battery 2, restricting the leftward movement of the top ring 57. The vertical sliding of the pressing post 59 against the clearance hole on the surface of the electric heating housing 1 restricts the rotation of the top ring 57, allowing the top ring 57 to move only up and down. The heating mechanism 5 also includes a return spring 53, which is disposed between the upper surface of the connecting plate 58 and the top wall of the electric heating housing 1. The return spring 53 is movably sleeved on the outer arc surface of the pressing post 59. When the pressing post 59 moves down, the return spring 53 extends and generates elastic force, which provides power for the automatic reset of the pressing post 59.Rubber pads 6 are provided between the upper surface of the arc-shaped heating plate 51 and the top wall of the electric heating housing 1 to connect the upper surface of the arc-shaped heating plate 51 and the top wall of the electric heating housing 1. The rubber pads 6 are borosilicate rubber pads, which can be used for a long time in a temperature range of -40 to 350 degrees Celsius, and guide the smoke to be discharged from the exhaust pipe of the electric heating housing 1.

[0021] The working principle of the electric heating device for heated cigarettes with built-in temperature measuring element provided by this utility model is as follows: During use, the operator pushes the connecting plate 58 downwards by pressing the column 59, causing the return spring 53 to extend and generate elastic force. The connecting plate 58 drives the two top rings 57 downwards, and the conical arc surface of the top rings 57 applies force to the vertical plate of the top plate 56, pushing the arc-shaped heating plate 51 away from the center of the cigarette insertion port of the electric heating housing 1. The guide column 54 slides inside the support cylinder 52, and the return spring 55 extends and generates elastic force, providing space for the insertion of the heated cigarette. Then, the heated cigarette is inserted through the cigarette insertion port on the lower surface of the electric heating housing 1. Between the three arc-shaped heating plates 51, after releasing the pressing post 59, the arc-shaped heating plates 51 are pushed back to their original positions by the elastic force of the first return spring 53 and the second return spring 55, so that the inner arc surfaces of the three arc-shaped heating plates 51 are in contact with the outer arc surface of the heated cigarette. The three arc-shaped heating plates 51 form a heating tube. Then, the single-chip microcomputer 3 powers on the arc-shaped heating plates 51, and heat is generated by the Joule effect to heat the heated cigarette. During the heating process, the temperature sensor 4 detects the temperature of the arc-shaped heating plates 51, and the single-chip microcomputer 3 adjusts the heating effect according to the detection results. The person sucks out the smoke generated during the heating process through the silicone mouthpiece 8.

[0022] It is worth noting that the microcontroller 3 disclosed in the above embodiments can be an AT89C4051 microcontroller, and the temperature sensor 4 can be freely configured according to the actual application scenario. It is recommended to use an IMG-5449 temperature sensor. The microcontroller 3 controls the operation of the temperature sensor 4 using methods commonly used in the prior art.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
