Description

Technical Field

[0001] This utility model relates to the field of heated non-combustible smoking devices, specifically to a heated smoking device that automatically detects the type of the end face of the cigarette holder. 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 heating device that automatically detects the type of cigarette end face. It can automatically distinguish the type of cigarette based on the cigarette end face, thus opening up a new path for heating devices to be compatible with multiple types of cigarettes.

[0008] The first aspect of this utility model provides a heated smoking device that automatically detects the type of cigarette end face. The heated smoking device has a photoelectric emitting tube and a photoelectric receiving tube symmetrically arranged at the entrance of the cigarette receiving cavity. The central axis of the emitting end of the photoelectric emitting tube and the central axis of the receiving end of the photoelectric receiving tube are set at a certain angle.

[0009] Preferably, the angle formed by the intersection of the central axis of the emitting end of the photoelectric emitting tube and the central axis of the receiving end of the photoelectric receiving tube is θ, and the range of θ is between 90-180°.

[0010] Preferably, the photoelectric emitting tube can be any one of an infrared emitting tube, a visible light emitting tube, or a laser emitting tube, and the corresponding photoelectric receiving tube can be any one of an infrared receiving tube, a visible light receiving tube, or a laser receiving tube corresponding to the photoelectric emitting tube.

[0011] Preferably, the inner diameter of the cigarette holder cavity is adapted to the outer diameter of the cigarette A;

[0012] Preferably, the main body of the smoking device further includes a housing, a control board, and a power supply, wherein the control board and the power supply are disposed within the housing and within the cigarette holder cavity.

[0013] The second aspect of this utility model provides a method for automatically detecting the end face of a cigarette stick, using the heating tobacco appliance described in the first aspect, the method comprising:

[0014] When a cigarette is inserted into the cigarette holder cavity, and the end face of the cigarette approaches the irradiation area of ​​the photoelectric emitting tube and the photoelectric receiving tube, the rays emitted by the photoelectric emitting tube are reflected by the end face of the cigarette. The photoelectric receiving tube receives the reflected light. When the intensity of the reflected light received by the photoelectric receiving tube is less than 40% (excluding 40%), the cigarette is a non-sealed cigarette with an exposed core section. When the intensity of the reflected light received by the photoelectric receiving tube is between 40% and 70% (including 40% and 70%), the cigarette is a particulate or non-particulate cigarette with a plug on the end face. When the intensity of the reflected light received by the photoelectric receiving tube is greater than 70% (excluding 70%), the cigarette is a particulate cigarette with a sealing element on the end face.

[0015] It should be noted that the light reflection intensity value mentioned above is the light reflection intensity value of the end face of the current mainstream cigarettes. It is data given after sample statistics, simulation and calculation analysis. This light intensity judgment value can be adjusted according to the actual situation.

[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 photoelectric emitter and a photoelectric receiver at the entrance of the cigarette holder cavity. By utilizing the different light reflection intensities of the end faces of various types of cigarettes, it can identify at least cigarettes with sealing paper end faces, cigarettes with tobacco shreds end faces, cigarettes with tobacco sheet end faces, and cigarettes with acetate fiber rod end faces. By adding information about the end faces of various types of cigarettes in the control board, even more types of cigarettes can be identified.

[0018] 2. In the preferred technical solution, this utility model is the first to combine photoelectric technology with heated non-combustible tobacco products to identify the cigarette end. Specifically, based on the different smoothness of different cigarette end faces, the light reflection intensity varies when illuminated by a light beam. By analyzing and classifying the existing cigarette end faces in advance and storing the reflection intensity values ​​of cigarettes with different end faces in the control board, automatic identification of cigarette type is achieved.

[0023] The present invention will be further described below through specific embodiments.

[0024] Example 1

[0025] like Figure 2 As shown, a heated smoking device that automatically detects the type of cigarette end face is provided. The heated smoking device has a photoelectric emitting tube 7 and a photoelectric receiving tube 8 symmetrically arranged at the entrance of the cigarette receiving cavity 1. The central axis of the emitting end of the photoelectric emitting tube 7 is set at a certain angle to the central axis of the receiving end of the photoelectric receiving tube 8.

[0026] The angle formed by the intersection of the central axis of the transmitting end of the photoelectric emitting tube 7 and the central axis of the receiving end of the photoelectric receiving tube 8 is θ, where θ equals 120°.

[0027] The photoelectric emitting tube 7 is an infrared emitting tube, and the photoelectric receiving tube 8 is an infrared receiving tube.

[0028] The inner diameter of the cigarette receiving cavity 1 is adapted to the outer diameter of the cigarette A.

[0029] The smoking device also includes a housing 13, a control board 14, and a power supply 15. The control board 14 and the power supply 15 are located inside the housing 13 and are located on the same side of the cigarette holder cavity 1.

[0030] Example 2

[0031] In this embodiment, the cigarette is a non-sealed type with the core section exposed.

[0032] This utility model provides a method for automatically identifying the cigarette A described above, using the heating tobacco appliance described in Embodiment 1 above, the method comprising:

[0033] When cigarette A is inserted into the cigarette receiving cavity 1, it first passes through the irradiation area of ​​infrared emitting tube 7 and infrared receiving tube 8. The infrared light emitted by infrared emitting tube 7 is reflected when it encounters the end face of cigarette A. The intensity of the reflected light received by infrared receiving tube 8 is 35% of the emitted light. Infrared receiving tube 8 feeds this signal back to the main control board 14. The main control board A determines that cigarette A is a non-sealed cigarette with an exposed core section based on the stored information on the intensity of the reflective tube of the plug type.

[0034] Example 3

[0035] In this embodiment, cigarette A is a cigarette sealed with sealing paper.

[0036] This utility model provides a method for automatically identifying the above-mentioned cigarette A, using the heating tobacco appliance described in Example 1, the method comprising:

[0037] When cigarette A is inserted into the cigarette receiving cavity 1, it first passes through the irradiation area of ​​the infrared emitting tube 7 and the infrared receiving tube 8. The infrared light emitted by the infrared emitting tube 7 is reflected when it encounters the end face of the cigarette A. The intensity of the reflected light received by the infrared receiving tube 8 is 80% of the emitted light. The infrared receiving tube 8 feeds this signal back to the main control board 14. The main control board A determines that the cigarette A is a cigarette sealed with sealing paper based on the stored reflection tube intensity information.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
