[0002] With the development of heated cigarette technology and consumers' pursuit of health, heated cigarettes are now sold in most countries.

[0003] Currently, heated cigarettes are mainly classified into several heating methods: inner core heating, outer perimeter heating, and electromagnetic induction heating. However, generally, a heating device only has one function and is only compatible with one type of heated tobacco cartridge. Users who want to experience cigarettes with different heating methods need to frequently change heating devices, which is quite cumbersome. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a heated cigarette device that solves the above problems by equipping a heating mechanism with at least two different heating methods.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: This application provides a heated cigarette device, which includes: a shell, a power supply system, a heating system, and a control system. The power supply system, the control system, and the heating system are disposed inside the shell. The power supply system supplies power to the heating system and the control system. The heating system is used to heat the cigarette contained inside the heated cigarette device during operation to generate smoke. The control system is used to generate control signals. The heating system includes: a first heating mechanism and a second heating mechanism. The first heating mechanism and the second heating mechanism have different heating methods to allow for different heating methods to be used to heat the cigarette. The heating methods include inner core heating, electromagnetic heating, and peripheral heating.

[0006] Furthermore, the first heating mechanism includes a heating needle and a first heating bracket, the first heating bracket forming a first heating chamber, and the heating needle being fixedly disposed at the bottom of the first heating chamber; when the cigarette is in the first heating chamber, the heating needle is inserted into the inside of the cigarette to heat the inner core of the cigarette.

[0007] Furthermore, the second heating mechanism includes an electromagnetic heating coil and a second heating bracket. The second heating bracket forms a second heating cavity. The electromagnetic heating coil is arranged around the center of the second heating cavity. When the cigarette is in the second heating cavity, the electromagnetic heating coil works in conjunction with the sensor of the cigarette to electromagnetically heat the cigarette.

[0008] Furthermore, the heating system also includes a third heating mechanism, which includes a heating tube and a third heating bracket. The third heating bracket forms a third heating chamber, and the heating tube is installed inside the third heating chamber. When the cigarette is in the third heating chamber, the heating tube heats the cigarette from the outside.

[0009] Furthermore, the heating system also includes circuit pins located at the far end of the heating system, through which the power supply system is electrically connected to the heating system.

[0010] Furthermore, the circuit pins include at least one first pin and at least one second pin, with the first pin and the second pin arranged symmetrically to each other.

[0011] Furthermore, the heating system also includes guide locating ribs located near the end of the heating system, through which the heating system is fixed to the inside of the outer casing.

[0012] Furthermore, a guide positioning groove is provided inside the outer casing to guide the movement of the guide positioning ribs so that the heating system is fixed inside the outer casing.

[0013] Furthermore, the heated cigarette device also includes a switch button, which is located on the surface of the casing and is used to receive user input and control the power system based on user input.

[0014] Furthermore, heated cigarette devices also include a cigarette sensor, which is used to detect the presence of cigarettes in the heating system.

[0015] Cigarettes, also known as aerosol-generating products, are a type of smoking product that includes an aerosol-forming matrix. These aerosols are generated through heating and can be directly inhaled into the lungs of the user through their mouth.

[0016] Preferably, the aerosol forming matrix is ​​a solid aerosol forming matrix. The aerosol forming matrix may include both solid and liquid components.

[0017] Preferably, the aerosol-forming matrix includes nicotine. In some preferred embodiments, the aerosol-forming matrix includes tobacco.

[0018] Heated cigarette smokers, also known as aerosol generating devices, can be used to describe devices that interact with an aerosol-forming matrix of an aerosol-generating product to generate aerosols.

[0019] Preferably, the aerosol generating device is a heated smoking device that interacts with the aerosol generating matrix of the aerosol generating product to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth.

[0020] The power source can be any suitable power source, such as a DC voltage source, like a battery.

[0021] In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate, or lithium polymer battery.

[0022] The control element can be a simple switch. Alternatively, the control element can be a circuit and may include one or more microprocessors or microcontrollers.

[0023] An aerosol generation system may include an aerosol generation device and one or more aerosol generation articles, wherein the aerosol generation device is configured with a corresponding number of heating chambers to contain the aerosol generation articles.

[0024] As can be seen from the above technical solution, the advantages and positive effects of the heated cigarette smoking device proposed in this application are as follows: This application provides heating devices equipped with at least two different heating modules (such as an inner core heating module, an electromagnetic heating module, and an outer heating module). Consumers can select different heating methods for smoking and experience through the control system, or the heating module can be automatically activated by inserting a cigarette. This can better meet the requirements of some consumers for heated cigarettes and enhance the user experience. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] This application provides a heated cigarette device, which includes: a housing 1, a power supply system 2, a heating system and a control system 3.

[0041] The outer casing 1 contains a power supply system 2, a control system 3, and a heating system. The power supply system 2 supplies power to the heating system and the control system 3. The heating system is used to heat the cigarettes contained inside the heated cigarette device during operation to generate smoke. The control system 3 is used to generate control signals.

[0042] Please refer to Figure 1 In the first embodiment of this application, the heating system includes a first heating mechanism 4 and a second heating mechanism 5. The first heating mechanism 4 and the second heating mechanism 5 have different heating methods to change the heating method of the cigarette.

[0043] The outer casing 1 has a guide positioning groove 8 inside.

[0044] The heated cigarette device also includes a switch button 9 and a cigarette sensor 10.

[0045] The switch button 9 is located on the surface of the housing 1 and is used to receive user operations and control the power system 2 according to the user operations.

[0046] For example, the heating system of this application can be started by a switch button. The switch button can be set to at least two parts, and the user can start the corresponding heating mechanism by pressing one of the button parts.

[0047] In addition, the heating system can also sense whether there is cigarette in the heating system through the cigarette sensor 10, so as to automatically heat the cigarette when the presence of cigarette in the heating system is detected.

[0048] For example, the cigarette sensor 10 can be an infrared sensor, which is installed in the heating system to detect whether an object is placed in the heating system, thereby activating heating.

[0049] Alternatively, the cigarette sensor 10 can also be a weight sensor. The weight sensor is located at the bottom of the heating system and is used to detect whether a weight change occurs in the heating system, thereby activating the heating.

[0050] Specifically, please refer to Figure 2 The first heating mechanism 4 includes a heating needle 42 and a first heating bracket 41.

[0051] The first heating bracket 41 constitutes the first heating cavity. The heating bracket is made of high-temperature resistant material and is constructed as a hollow structure.

[0052] The heating needle 42 is fixedly installed at the bottom of the first heating chamber.

[0053] When the cigarette is in the first heating chamber, the heating needle 42 is inserted into the inside of the cigarette to heat the inner core.

[0054] It is understandable that the heating needle 42 is a needle-shaped heating device that converts electrical energy or other energy into heat energy to achieve precise temperature control. Its core principle is to use a special needle as a heat carrier and to generate controllable heat locally at the needle tip or needle body by adjusting the current, voltage or heat source intensity.

[0055] The heating system also includes circuit pins located at the far end of the heating system, and the power supply system 2 is electrically connected to the heating system through the circuit pins.

[0056] The circuit pins include at least one first pin 71 and at least one second pin 72, which are symmetrically arranged. The heating needle 42 is connected to the first pin 71 and the second pin 72 inside the hollow structure.

[0057] The heating system also includes a guide locating rib 73 located near the end of the heating system, and the heating system is fixed to the inside of the outer shell 1 by the guide locating rib 73.

[0058] It is understood that the height of the guide positioning rib 73 is the same as the height of the guide positioning groove 8. The guide positioning groove 8 of the outer shell 1 guides the guide positioning rib 73 to move so that the heating system is fixed inside the outer shell 1.

[0059] Please refer to Figure 3 The second heating mechanism 5 includes an electromagnetic heating coil 52 and a second heating bracket 51.

[0060] The second heating bracket 51 forms the second heating cavity, and the electromagnetic heating coil 52 is arranged around the center of the second heating cavity inside the second heating cavity.

[0061] When the cigarette is in the second heating chamber, the electromagnetic heating coil 52 works in conjunction with the sensor installed on the cigarette to electromagnetically heat the cigarette.

[0062] A sensor is a material that can convert electromagnetic energy into heat. When placed in a wave electromagnetic field, the eddy currents induced in the sensor cause it to heat up.

[0063] When the elongated receptor is positioned to make thermal contact with the aerosol-forming matrix, the aerosol-forming matrix is ​​heated by the receptor.

[0064] The cigarette is designed to engage with an electrically operated heated cigarette device, which includes an induction heating source. The induction heating source or sensor generates a fluctuating electromagnetic field to heat a sensor located within the fluctuating electromagnetic field.

[0065] In use, the cigarette and the heated cigarette device are combined so that the sensor is located within the fluctuating electromagnetic field generated by the sensor.

[0066] The length of the receptor is significantly greater than its width or thickness, for example, more than twice its width or thickness. Therefore, the receptor can be described as an elongated receptor. The receptor can be arranged approximately longitudinally within the tobacco of a cigarette.

[0067] This means that the length of the elongation receptors is arranged approximately parallel to the longitudinal direction of the cigarette tobacco, for example, within plus or minus 10 degrees of the longitudinal direction of the cigarette tobacco.

[0068] In a preferred embodiment, the elongation receptor may be located at the radial center of the cigarette tobacco and extend along the longitudinal axis of the cigarette tobacco.

[0069] The sensor can be made of any material that can be heated by induction to a temperature sufficient to generate an aerosol matrix.

[0070] Preferred receptors include metals or carbon.

[0071] Preferred receptors may include ferromagnetic materials, such as ferrite, ferromagnetic steel, or stainless steel. Suitable receptors may be aluminum or may include aluminum.

[0072] The preferred sensor may be made of 400 series stainless steel, such as 410, 420 or 430 grade stainless steel.

[0073] Different materials will consume different amounts of energy when placed in an electromagnetic field with similar frequency and field strength. Therefore, the parameters of the sensor, such as material type, length, width, and thickness, can be varied within a known electromagnetic field to provide the required energy consumption.

[0074] The preferred sensor may be heated to a temperature exceeding 250 degrees Celsius. A suitable sensor may include a non-metallic core having a metallic layer disposed on the non-metallic core, such as metallic traces formed on the surface of a ceramic core.

[0075] The sensor may have an outer protective layer, such as a ceramic or glass protective layer encapsulating the elongated sensor, thereby forming a complete heating element. The sensor may include a protective coating formed of glass, ceramic, or inert metal on the core of the sensor material.

[0076] The receptors are arranged to be in thermal contact with the aerosol-forming matrix. Therefore, when the receptors are heated, the aerosol-forming matrix is ​​heated and aerosols are formed.

[0077] In one embodiment, a heating element including a sensor is inserted into an aerosol forming matrix, and the heated cigarette device may include one or more elongated heating elements.

[0078] In another embodiment, the cigarette tobacco may contain receptors.

[0079] Alternatively, cigarette tobacco may include multiple receptors, and the receptors may be elongated, granular, mesh-like, radial, tubular, hourglass-shaped, spiral, etc.

[0080] Heated cigarette devices can generate a fluctuating electromagnetic field between approximately 1 MHz and 30 MHz, for example, between 2 MHz and 10 MHz, or for example, between 5 MHz and 7 MHz, through the induction coil of the induction transmitter.

[0081] Preferably, the heated cigarette device can generate a fluctuating electromagnetic field with a field strength (H field) between 1 kA / m and 5 kA / m, for example between 2 kA / m and 3 kA / m, for example about 2.5 kA / m.

[0082] Heated cigarette devices are portable or handheld devices that can be comfortably held between the fingers of one hand. The shape of a heated cigarette device is generally cylindrical. Heated cigarette devices can have a length between approximately 70 mm and approximately 120 mm.

[0083] Please refer to Figure 4 and Figure 5 In the heated cigarette device of the second embodiment provided in this application, the heating system further includes a third heating mechanism 6 based on the first embodiment.

[0084] The third heating mechanism 6 includes a heating tube 62 and a third heating bracket 61. The third heating bracket 61 forms a third heating chamber, and the heating tube 62 is disposed inside the third heating chamber.

[0085] When the cigarette is in the third heating chamber, the heating tube 62 heats the cigarette from the outside.

[0086] The switch button 9 of the heated cigarette device in the second embodiment has at least three parts. The third heating mechanism can be activated by pressing a button in one of the parts of the switch button 9.

[0087] The external heating technology indirectly transfers heat to the tobacco material through the external structure of the heating tube 62 (such as carbon heat-conducting material or metal inductor), and uses heat convection and heat radiation to make the tobacco release nicotine and flavor substances in the range of 240-350℃.

[0088] This technology requires optimizing the heat conduction path to ensure that heat is evenly distributed on the tobacco surface, avoiding local overheating that could lead to scorching or insufficient heating that would affect the taste.

[0089] Understandably, consumers can choose different heating methods to smoke and experience through the control system 3, or they can activate the heating system by inserting the cigarette, which can better meet the requirements of some consumers for heated cigarettes and improve the user experience.

[0090] It should be noted that the first heating mechanism 4 and the second heating mechanism 5 in the heated cigarette device of the second embodiment have been described above, and will not be repeated here.
