Abstract
Description
Technical Field
[0001] This utility model relates to the field of heated non-combustible smoking devices, specifically to a heated smoking device with a cigarette end face detection function. Background Technology
[0002] Heated cigarettes, also known as heated tobacco or low-temperature cigarettes, are a type of product that combines a heating device and HTP (Heated Tobacco Products) cigarettes. The HTP cigarettes are heated to a certain temperature using a special heating device, and the HTP cigarettes can release smoke for people to inhale.
[0003] In terms of heated smoking devices, to match the smoke release from the e-cigarette cartridges and take into account factors such as smoke stability and temperature control, heated smoking devices can be mainly classified into resistance heating devices, electromagnetic heating devices, and airflow heating devices based on their heating methods.
[0004] Regarding HTP cigarettes, the cigarette end face (for some types of cigarette end faces, please refer to...) Figure 1 There are significant differences between granular cigarettes and non-granular cigarettes. Granular cigarettes have a sealing element (usually sealing paper) near the end containing the granules to prevent the smoke particles from scattering. Non-granular cigarettes, on the other hand, have a filling material made of tightly packed filaments or sheets of smoke-producing material. The tobacco shreds or sheets are mutually restrained and do not scatter, so they generally do not have a sealing element. Therefore, non-granular cigarettes are also called cigarettes with exposed filling material. However, in existing technology, there are several situations where a plug (commonly a cellulose acetate rod) is added to the end of a non-granular cigarette. For example, in resistance heating, a plug is also added near the end containing the non-granular filling material to prevent the filling material from scattering into the device after smoking. Another example is non-granular cigarettes with an electromagnetic induction plate. Because the electromagnetic induction plate and the filling material are made of different materials with different hardness, they cannot completely adhere. To prevent the electromagnetic induction plate or the filling material from detaching, a plug is also added near the end of the filling material. Note that the terms "end cap" and "sealing paper" are distinguished in this article. Although both are placed at the far end of the cigarette, "end cap" refers to a cylindrical section with a certain axial length (or thickness), such as at least 2 mm, preferably at least 5 mm; while the axial length or "thickness" of the sealing paper is almost negligible, usually less than 1 mm, or even less than 0.5 mm.
[0005] Because there are significant structural differences between sealed cigarettes and cigarettes with exposed core materials, and the materials used for sealing components also differ significantly, the heating types and heating curves required for each type of cigarette are not the same. Therefore, in order to provide users with the best smoking experience, existing technologies mainly solve the problem of large differences in heating curves by designing the smoking device as a dedicated device, that is, designing the cigarette heater to perfectly match the characteristics of different cigarette types. The advantage of setting up a dedicated smoking device is that the cigarette heater has a dedicated heating program. When heating cigarettes with it, the heated cigarettes can release a preset smoke quality and amount of smoke, allowing consumers to have a better smoking experience. However, if consumers want to smoke another type of heated cigarette, they must use a dedicated cigarette heater corresponding to that other cigarette type. This undoubtedly reduces the compatibility of the smoking device. Forcing the use of a certain type of heated smoking device to smoke another type of cigarette will significantly reduce the consumer's smoking experience due to the incompatible heating curve. Therefore, it is necessary for a smoking device to be compatible with all types of cigarettes and to be able to identify the cigarette type and select the heating program that matches that cigarette type. The first priority is to identify the cigarette type.
[0006] To address the above problems, this utility model is proposed. Utility Model Content
[0007] To address the problem that traditional cigarette heaters can only provide the optimal heating program for one type of cigarette, the purpose of this invention is to provide a heated cigarette device with a cigarette end face detection function. This device can automatically distinguish the type of cigarette based on the cigarette end face, opening up a new path for heated cigarette devices to be compatible with multiple types of cigarettes.
[0008] The technical solution adopted by this utility model is:
[0009] The first aspect of this utility model provides a heated smoking device with a cigarette end face detection function. The smoking device is provided with a camera at the entrance of the cigarette receiving cavity. The camera intersects with the central axis of the cigarette receiving cavity to form an angle γ, the range of which is between 45° and 90°.
[0010] Preferably, the heating device is further provided with an LED light source at the inlet of the cigarette holder cavity, and the LED light source and the camera are located on the same side of the inlet of the cigarette holder cavity. Optimally, there are two LED light sources. When there are two LED light sources, the two LED light sources are mirror-distributed on both sides of the camera. It should be noted that the LED light source should be positioned to avoid light shining on the camera, so as to prevent affecting the image acquisition effect of the camera.
[0011] Preferably, the area of the inner wall of the cigarette holder cavity that can be illuminated by the LED light source needs to be blackened to reduce the reflection of the light emitted by the LED light source on the inner wall of the cigarette holder cavity, which would interfere with the image capture effect of the cigarette end.
[0012] Preferably, the inner diameter of the cigarette holder cavity is adapted to the outer diameter of the cigarette.
[0013] Preferably, the main body of the smoking device includes at least a housing, a control board, and a power supply, wherein the control board and the power supply are disposed inside the housing.
[0014] This utility model provides a heated smoking device with a cigarette end face detection function. Using the heated smoking device described in the first aspect, the method is to insert a cigarette A into the cigarette receiving cavity. When the cigarette end face is close to the camera, the camera takes a picture of the cigarette end face. The control board compares the cigarette end face image with pre-stored end face images of different types of cigarettes to identify the type of cigarette.
[0015] The images of cigarette end faces pre-stored in the control motherboard can be added or removed as needed.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model is the first to install a camera at the entrance of the cigarette holder cavity, which can identify various types of cigarettes with different ends by detecting the end face of the cigarette.
[0018] 2. In the preferred technical solution, the heating device is equipped with a camera at the entrance of the cigarette holder cavity. The central axis of the camera's illumination end intersects with the central axis of the cigarette holder cavity to form an angle γ, the range of which is between 45-90°. This ensures that the camera can be aimed at the cigarette end face for complete imaging, accurately determine the type of cigarette end face, and thus determine the type of cigarette.
[0019] 3. In the preferred technical solution, an LED light source is added at the entrance of the cigarette holder cavity of the heated smoking device, which can provide light for the camera to capture images, ensure the clarity of the camera images, and ultimately ensure that the smoking device can accurately determine the type of cigarette.
[0020] 4. In the preferred technical solution, the heated smoking device is equipped with a camera at the entrance of the cigarette holder cavity. The camera captures the image of the cigarette end and transmits it to the control motherboard. The control motherboard compares the image captured by the camera with the reference image stored in its own memory to determine the type of cigarette, thus providing technical support for the development of heated smoking devices that are compatible with multiple types of cigarettes.
