Abstract
Description
Technical Field
[0001] This invention relates to the field of heated non-combustible tobacco products, specifically to a heated tobacco product and a detection method with a cigarette type detection function. Background Technology
[0002] Heated cigarettes, also known as heated tobacco products or low-temperature cigarettes, are a type of product that combines a heating device (HTP) with the cigarette itself. A special heating device heats the HTP cigarette to a specific temperature, releasing smoke for the smoker to inhale. Due to their lower harm and ability to largely replicate the pure taste of traditional cigarettes, heated cigarettes have gained popularity and attention among smokers in recent years.
[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. Cigarettes can also be categorized into granular and non-granular cigarettes based on the filler material. 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 the rolling process.
[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 invention is proposed. Summary of the Invention
[0007] To address the problem that traditional cigarette heaters can only provide the optimal heating program for one type of cigarette, the present invention aims to provide a device that can detect whether the cigarette is particulate or non-particulate, thus opening a new path for heated cigarette devices to be compatible with multiple types of cigarettes.
[0008] The first aspect of this invention provides a heated smoking device with a cigarette type detection function, wherein at least one trigger switch assembly is provided at the inlet of the cigarette receiving cavity of the heated smoking device, the trigger switch assembly comprising:
[0009] The trigger button is fixed to the main body of the smoking device;
[0010] A limiting ring, which is fixed to the main body of the smoking device;
[0011] The first movable rod has a first end that protrudes inward from the inner wall of the cigarette receiving cavity, the first movable rod passes through the limiting ring and its second end is in active contact with the trigger button; a first flange is provided at the non-end position of the first movable rod.
[0012] The first return spring is sleeved on the outer wall of the first moving rod, with one end abutting against the limiting ring and the other end abutting against the first flange.
[0013] Preferably, a correction component is further provided at the entrance of the cigarette receiving cavity, the correction component being positioned relative to the trigger switch component, the correction component comprising:
[0014] The limiting cavity is fixed to the main body of the smoking device. It is a cavity structure with a through hole at one end and a seal at the other end.
[0015] The second moving rod has a first end that protrudes inward at least partially from the inner wall of the cigarette receiving cavity, and a second end that passes through the end of the limiting cavity with a through hole. The limiting cavity also provides space for the second end of the second moving rod to move. The second moving rod is also provided with a second flange at the non-end position within the limiting cavity.
[0016] The second return spring is sleeved on the outer wall of the second moving rod, with one end abutting against the inner wall of the sealing end of the limiting cavity and the other end abutting against the second flange.
[0017] The preferred embodiment of this solution is to set a trigger switch assembly at the inlet of the cigarette receiving cavity, and to set a correction assembly at the inlet of the cigarette receiving cavity relative to the position of the trigger switch assembly.
[0018] Preferably, the first end of the first moving rod and the first end of the second moving rod are further provided with rollers, and the outer edge of the rollers protrudes inward at least partially from the inner wall of the cigarette receiving cavity.
[0019] Preferably, the inner diameter of the cigarette holder cavity is adapted to the outer diameter of the cigarette.
[0020] Preferably, the distance by which the outermost edge of the first end of the first moving rod protrudes from the inner wall of the cigarette receiving cavity, and the distance by which the outermost edge of the first end of the second moving rod protrudes from the inner wall of the cigarette receiving cavity, are both 0.1-0.8 mm. It should be noted that setting the distance by which the outermost edge of the first end of the first moving rod protrudes from the inner wall of the cigarette receiving cavity to 0.1-0.8 mm ensures that the force exerted by the outer wall of the cigarette on the first end (roller) of the first moving rod allows the first moving rod to move and connect with the trigger button, without affecting the appearance of the cigarette. The distance by which the outermost edge of the first end of the second moving rod protrudes from the inner wall of the cigarette receiving cavity to 0.1-0.8 mm applies a force to the cigarette in the opposite direction when it is inserted, ensuring that the central axis of the cigarette coincides with the central axis of the cigarette receiving cavity, facilitating cigarette insertion without affecting the appearance of the cigarette.
[0021] Preferably, the main body of the smoking device further includes a housing, a control board, and a power supply. The control board and the power supply are located inside the housing, for example, the control board and the power supply can be located on the same side or different sides of the cigarette holder cavity.
[0022] A second aspect of the present invention provides a method for detecting cigarette type, using the heated smoking device described in the first aspect of the present invention, the method comprising:
[0023] When a cigarette is inserted into the cigarette receiving cavity, as the covering material at the inserted end of the cigarette slides into contact with the first end of the first moving rod, the first end of the first moving rod applies a radially inward force to the cigarette.
[0024] When the covering material is a rigid material, the first moving rod moves away from the cigarette receiving cavity, the first return spring is compressed, and the end of the second end of the first moving rod contacts the switch button, triggering the switch to open. The control board determines that the cigarette is a granular cigarette based on this signal.
[0025] When the covering material is soft, the cigarette is deformed locally, but the first moving rod does not move and cannot drive the end of the second part to contact the switch button. The trigger switch cannot be turned on, and the control board determines that the cigarette is a non-particulate cigarette based on this signal.
[0026] Compared with the prior art, the present invention has the following beneficial effects:
[0027] 1. This invention is the first to propose setting a trigger switch assembly at the entrance of the cigarette holder cavity to detect the hardness of the cigarette covering material, and further determine whether the cigarette is a particulate or non-particulate type, providing technical support for the compatibility of smoking devices with multiple types of cigarettes.
[0028] 2. In the preferred technical solution, the trigger switch assembly is set at the entrance of the cigarette receiving cavity, which avoids the influence of the cigarette support section, cooling section, etc. on the trigger switch assembly, and effectively ensures that the trigger switch assembly can be accurately opened according to the hardness of the covering material.
[0029] 3. In the preferred technical solution, the distance between the outermost edge of the first end of the first moving rod (or 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 first moving rod, the force exerted by the outer wall of the cigarette on the first end of the first moving rod (roller) can move the first moving rod to trigger the switch button, but will not affect the appearance of the cigarette.
[0030] 4. In the preferred technical solution, there is one trigger switch assembly, and a correction assembly is set at the relative position of the trigger switch. During the process of inserting the cigarette downward into the cigarette receiving cavity, the correction assembly can apply a radially inward force to the outer wall of the cigarette. The direction of this force is opposite to the direction of the force applied to the outer wall of the cigarette by the trigger switch assembly. This ensures that the cigarette is in a centered position when it enters the cigarette receiving cavity, improves the reliability of the trigger switch assembly in testing the hardness of the covering material, and ensures that the inserted cigarette is evenly distributed in the cigarette receiving cavity. This not only facilitates cigarette insertion and smoking, but also keeps the smoked cigarette as intact and aesthetically pleasing as possible. Attached Figure Description

Detailed Implementation
[0035] The present invention will be further described below through specific embodiments.
[0036] Example 1
[0037] like Figure 1 As shown, a heated smoking device with a cigarette type detection function is provided at the entrance of the cigarette receiving cavity 1 of the heated smoking device. The two are arranged opposite to each other, wherein the trigger switch assembly 9 includes:
[0038] Trigger button 91, which is fixed to the main body of the smoking device;
[0039] The limiting ring 92 is fixed to the main body of the smoking device;
[0040] The first moving rod 93 has its first end 931 protruding inward at least partially from the inner wall of the cigarette receiving cavity 1. The first moving rod passes through the limiting ring 92 and its second end 932 is in active contact with the trigger button 911. A first flange 933 is provided at the non-end position of the first moving rod 93.
[0041] The first return spring 94 is sleeved on the outer wall of the first moving rod 93, with one end abutting against the limiting ring 92 and the other end abutting against the first flange 933.
[0042] A correction component 10 is also provided at the entrance of the cigarette receiving cavity 1. The correction component 10 is positioned relative to the trigger switch component 9. The correction component 10 includes:
[0043] The limiting cavity 101 is fixed to the main body of the smoking device. It is a cavity structure with a through hole at one end and a seal at the other end.
[0044] The second moving rod 102 has a first end 1021 that at least partially protrudes inward from the inner wall of the cigarette receiving cavity 1, and a second end 1022 that passes through the end of the limiting cavity 101 with a through hole. The limiting cavity 101 also has space for the second end 1022 of the second moving rod to move. The second moving rod 102 is also provided with a second flange 1023 at the non-end position of the limiting cavity 101.
[0045] The second reset spring 103 is sleeved on the outer wall of the second moving rod 102, with one end abutting against the inner wall of the sealing end of the limiting cavity 101 and the other end abutting against the second flange 1023.
[0046] The inner diameter of the cigarette receiving cavity 1 is adapted to the outer diameter of the cigarette A.
[0047] The distance by which the outermost edge of the first end 931 of the first moving rod protrudes from the inner wall of the cigarette receiving cavity 1, and the distance by which the first end 1021 of the second moving rod 102 protrudes inward from the inner wall of the cigarette receiving cavity 1, are both 0.3 mm.
[0048] The main body of the smoking device also includes a housing 13, a control board 14 and a power supply 14. The control board 14 and the power supply 14 are located inside the housing 13 and are located on the same side of the cigarette holder cavity 1.
[0049] Example 2
[0050] In this embodiment, cigarette A is a non-particulate cigarette.
[0051] like Figure 2 As shown in Figure a, a method for automatically testing the above-mentioned cigarette type A is provided, using the heating tobacco appliance described in Example 1, the method comprising:
[0052] When cigarette A is inserted into cigarette receiving cavity 1, the covering material at the insertion end of cigarette A slides into contact with the first end 931 of the first moving rod 93. The first end 931 of the first moving rod applies a radial inward force to the cigarette. Since the covering material is a soft material, cigarette A is partially deformed. The first moving rod 93 does not move and cannot drive the end of the second end 932 to contact the switch button 911. The trigger switch 91 cannot be turned on. The control board determines that the cigarette is a non-particulate cigarette based on this signal.
[0053] Example 3
[0054] In this embodiment, cigarette A is a granular cigarette.
[0055] like Figure 2 As shown in b, a method for detecting the above-mentioned particulate cigarette without a pre-installed heating core is provided, using the heating device described in Example 1, the method comprising:
[0056] When cigarette A is inserted into the cigarette receiving cavity 1, the covering material at the insertion end of cigarette A slides into contact with the first end 931 of the first moving rod 93. The first end 931 of the first moving rod applies a radial inward force to the cigarette. Since the covering material is a hard material, the first moving rod 93 moves away from the cigarette receiving cavity, and the first return spring 94 is compressed. The end of the second end 932 of the first moving rod contacts the switch button 911, triggering the switch 91 to open and feeding back a signal to the control main board. The control main board 14 determines that the cigarette is a granular cigarette based on the signal.
[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention 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 the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
