Abstract
Description
Technical Field
[0001] This utility model relates to the field of heated non-combustible smoking devices, specifically to a heated smoking device capable of detecting the type of cigarette covering material. Background Technology
[0002] Heated cigarettes, also known as heated tobacco or low-temperature cigarettes, are a type of product that combines heated tobacco products (HTPs) with a specially designed heating device. The HTP cigarette is heated to a certain temperature using a special heating device, and then it releases smoke for people to inhale.
[0003] In terms of heated smoking appliances, in order to match the release of cigarette smoke and take into account factors such as smoke stability and temperature control, heated smoking appliances can be mainly classified into resistance heating type, electromagnetic heating type, and airflow heating type based on the heating method.
[0004] Regarding HTP cigarettes, the mainstream HTP cigarettes currently consist mainly of a filler, cooling barrier, filter, and covering material. The filler is primarily divided into granular and non-granular types based on its shape. Based on the filler material, cigarettes can be categorized as granular or non-granular. Different types of fillers are matched with covering materials of varying hardness. For example, granular fillers often use paper tubes as the covering material. Since the filling method for granular cigarettes involves filling the tobacco particles into this rigid paper tube, the paper tube must have sufficient hardness and rigidity to ensure smooth filling and prevent deformation. Non-granular cigarettes (such as shredded tobacco or sheet tobacco) use cigarette paper as the covering material. Traditional rolling processes are used to wrap the shredded or sheet tobacco particles inside the cigarette paper; therefore, the cigarette paper must be flexible to facilitate rolling.
[0005] Because particulate and non-particulate cigarettes differ significantly in structure and core shape, the required heating types and heating curves are also different. Therefore, in order to provide users with the best smoking experience, existing technologies mainly address the issue of large differences in heating curves by designing the smoking device as a dedicated device. That is, according to different types of cigarettes, the cigarette heater is designed to be perfectly matched with the characteristics of the cigarette. 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 can detect the type of cigarette covering material. It can automatically test and distinguish whether the cigarette is particulate or non-particulate based on the type of covering material, thus opening up a new path for heating devices to be compatible with multiple types of cigarettes.
[0008] The technical solution that can be adopted by this utility model is:
[0009] The first aspect of this utility model is to provide a heated smoking device capable of detecting the type of cigarette covering material, wherein at least one switch assembly is provided at the inlet of the cigarette receiving cavity of the smoking device, the switch assembly comprising:
[0010] The switch is fixed to the main body of the smoking device, and the switch side wall is equipped with a switch button and a lever fulcrum;
[0011] The lever has a first end that at least partially protrudes from the inner wall of the cigarette holder cavity, a second end that is connected to the fulcrum, and a lever arm that can movably contact the switch button. Preferably, the second end of the lever is hinged to the fulcrum.
[0012] Preferably, the first end of the lever is further provided with a roller, and the outer edge of the roller at least partially protrudes from the inner wall of the cigarette receiving cavity.
[0013] Preferably, the inner diameter of the cigarette holder cavity is adapted to the outer diameter of the cigarette;
[0014] Preferably, the distance by which the outermost edge of the first end of the lever protrudes from the inner wall of the cigarette receiving cavity is 0.1-0.8 mm.
[0015] 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.
[0016] The second aspect of this utility model is to provide a method for detecting cigarette wrapping materials, using the smoking device described in the first embodiment, the method comprising:
[0017] When the cigarette is inserted into the cigarette holder, as the covering material at the inserted end of the cigarette slides into contact with the first end of the lever, the first end of the lever applies a radially inward force to the cigarette.
[0018] When the covering material is a rigid material, the lever rotates, thereby driving the lever arm to press the switch button, the switch is turned on, and the control board determines that the cigarette is a granular cigarette based on this signal;
[0019] When the covering material is soft, the cigarette is deformed locally, but the lever does not rotate and cannot drive the lever arm to press the switch button. The switch cannot be turned on, and the control board determines that the cigarette is a non-particulate cigarette based on this signal.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] 1. This utility model is the first to set a switch component at the entrance of the cigarette receiving cavity to detect the hardness of the cigarette covering material and further determine whether the cigarette is a granular cigarette or a non-granular cigarette.
[0022] 2. In the preferred technical solution, the switch assembly is located at the entrance of the cigarette receiving cavity, which avoids the influence of the cigarette support section, cooling section, etc. on the triggering of the switch assembly, and effectively ensures that the switch assembly can accurately trigger the switch according to the hardness of the covering material.
[0023] 3. In the preferred technical solution, the distance between the outermost edge of the first end of the lever (the outermost edge of the roller) and the inner wall of the cigarette receiving cavity is set to 0.1-0.8mm. This fully considers that when the outer wall of the cigarette contacts the first end of the lever (the roller), the force exerted by the outer wall of the cigarette on the first end of the lever (the roller) can cause the lever to rotate and trigger the switch, but will not affect the appearance of the cigarette.
[0024] 4. In the preferred technical solution, the number of switch components is at least one, and preferably two. When the number of switch components is two or more, each switch component is evenly distributed around the inlet of the cigarette receiving cavity. This improves the reliability of the switch components in detecting the hardness of the covering material, and at the same time ensures that the inserted cigarettes are evenly distributed in the cigarette receiving cavity. This not only facilitates the insertion and smoking of the cigarettes, but also keeps the smoked cigarettes as intact and aesthetically pleasing as possible. Attached Figure Description

[0030] The present invention will be further described below through specific embodiments.
[0031] Example 1
[0032] like Figure 1 As shown, a heated smoking device capable of detecting the type of cigarette covering material is provided. At the entrance of the cigarette receiving cavity 1 of the heated smoking device, two switching assemblies are symmetrically arranged circumferentially along the cigarette receiving cavity 1. Each switching assembly is as follows: Figure 2 The following are included:
[0033] Switch 3 is fixed to the main body of the smoking device. Switch button 31 and lever fulcrum 32 are provided on the side wall of switch 3.
[0034] Lever 4, the first end 41 of the lever protrudes inward from the inner wall of the cigarette receiving cavity 1, the second end 42 of the lever is hinged to the lever fulcrum 32, and the lever arm 43 of the lever can be pressed into contact with the switch button 31.
[0035] The first end 41 of the lever is also provided with a roller 411, the outer edge of which protrudes from the inner wall of the cigarette holder cavity 1.
[0036] The inner diameter of the cigarette receiving cavity 1 is adapted to the outer diameter of the cigarette A;
[0037] The distance from the outermost edge of the first end 41 of the lever protruding from the inner wall of the cigarette receiving cavity 1 is 0.5 mm.
[0038] The main body of 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.
[0039] Example 2
[0040] In this embodiment, cigarette A is a granular cigarette.
[0041] like Figure 3 As shown in Figure a, a method for detecting the type of cigarette wrapping material is provided, using the heated smoking device described in Example 1, the method comprising:
[0042] When cigarette A is inserted into cigarette receiving cavity 1, during the sliding contact between the covering material of the inserted end of the cigarette and the first end 41 of the lever, the first end 41 of the lever applies a radial inward force to the cigarette. The covering material is a hard material. The lever 4 rotates around the lever axis 32, which drives the lever arm 43 to press the switch button 31. The switch 3 is turned on, and the control board determines that the cigarette is a granular cigarette based on the signal.
[0043] Example 4
[0044] In this embodiment, cigarette A is a non-particulate cigarette.
[0045] like Figure 3 As shown in Figure b, a method for detecting the type of cigarette wrapping material, using the heated smoking device described in Example 1, the method includes:
[0046] When cigarette A is inserted into cigarette receiving cavity 1, during the sliding contact between the covering material of the inserted end of the cigarette and the first end 41 of the lever, the first end 41 of the lever applies a radial inward force to the cigarette. Because the covering material is a soft material, cigarette A is locally deformed, but the lever does not rotate and cannot drive the lever arm 43 to press the switch button 31. The switch 3 cannot be turned on, and the control board determines that the cigarette is a non-particulate cigarette based on this signal.
