[0002] Heated tobacco products are a new type of tobacco product technology that uses an electric current to drive a heater to generate temperature, thereby heating the tobacco without burning it.

[0003] Gas path design is a crucial aspect of heat-not-burn appliances. The design of the gas path and its size directly determines the quality of the vaping experience, most noticeably in the draw resistance. Secondly, the size of the gas path also affects smoke release. However, vaping is a highly subjective experience; some consumers prefer higher draw resistance, while others prefer lower resistance. Currently, the gas path structure of heat-not-burn appliances cannot be automatically adjusted after manufacturing. Combined with the inherent draw resistance variations in cigarettes themselves, current appliances cannot satisfy the diverse vaping preferences of all consumers. Utility Model Content

[0076] like Figure 1As shown in Figure 8, this patent provides a specific embodiment of a heated smoking device with adjustable airflow. The heated smoking device 2 includes a heating tube 22 for accommodating a heated cigarette 1 and heating the cigarette 1 within the heating tube to generate an aerosol for inhalation. The heated smoking device 2 also includes an airflow regulating device 21 located above the heating tube 22. The heated cigarette 1 is fixed in the heating tube 22 by the airflow regulating device 21. The airflow regulating device 21 includes an air intake structure 212 and a sliding component 213. The air intake structure 212 is disposed within the coverage area of ​​the sliding component 213, which is at least partially disposed on the surface of the housing of the heated smoking device 2, thereby allowing adjustment of the airflow rate of the air intake structure 212 via the sliding component 213. The heated cigarette 1 includes a smoke-generating section and a filtering section. The smoke-generating section contains an aerosol matrix capable of generating aerosols. Preferably, the smoke-generating section is fixed in the heating tube 22 by the airflow regulating device 21.

[0077] More specifically, the sliding component 213 is at least partially disposed on the housing surface of the heated smoke appliance 2, and the sliding displacement is directly and manually controlled by the consumer. When sliding, the coverage area of ​​the air intake structure 212 is changed by blocking or opening the number or size of the covered air intake structure 212, thereby achieving the purpose of controlling the size of different air passages.

[0078] For details, please refer to Figure 3 The sliding assembly 213 includes a sliding cover 2131, a slide rail 2132, and a slider 2133. The sliding cover 2131 is disposed on the surface of the housing of the heating smoke appliance 2. The slide rail 2132 is fixed inside the sliding cover 2131. The air intake structure 212 is disposed close to the slider 2133. The sliding cover 2131 slides on the slider 2133 via the slide rail 2132 to change the coverage area of ​​the air intake structure 212, thereby adjusting the air intake flow rate of the air intake structure 212 by changing the coverage area.

[0079] Specifically, the airflow regulating device 21 also includes a housing 211 and an inner housing 216. The housing 211 is embedded and fixed in the inner housing 216. The air intake structure 212 is disposed on the housing of the housing 211. The sliding component 213 is arranged above the air intake structure 212 and covers the air intake structure 212. Preferably, the sliding cover 2131 can be disposed on the housing surface of the heated smoke appliance 2 and can be directly manually adjusted by the consumer. The coverage area generated by the sliding cover 2131 on the housing 211 does not exceed the area of ​​the main structure of the housing 211.

[0080] For details, please refer to Figure 4 At least three air intake structures 212 are provided, and the positions of the air intake structures 212 are triangularly distributed within the coverage area of ​​the sliding axis of the sliding component 213.

[0081] More specifically, the air intake structure 212 is in the shape of a hole or slot, and its size and number can be arbitrarily set according to the specific structure.

[0082] For details, please refer to Figure 5 The airflow regulating device 21 also includes a silicone pad 214, which is fixedly connected to the sliding cover 2131 and in close contact with the outer casing 211, so that the entire sliding cover 2131 assembly is in a sealed state.

[0083] Specifically, the silicone pad 214 has an internal hollow structure, and the slide rail 2132 is located inside the silicone pad 214.

[0084] Specifically, the slider 2133 has a T-shaped structure, and the slide rail 2132 has a groove for relative movement of the slider 2133. The bottom of the slider 2133 is fixed to the outer shell 211, and the top of the slider 2133 is slidably connected to the slide cover 2131 via the slide rail 2132. Preferably, the slider 2133 moves relative to the slide rail 2132 within the groove. This can be understood as the slider 2133 remaining in a fixed position, while the slide cover 2131 drives the slide rail 2132 to move. More specifically, the bottom of the slider 2133 can be integrally formed with the outer shell 211. As another implementation, a slider fixing member 2134 is fixedly provided on the outer shell 211. The slider 2133 is hollow internally, and the slider 2133 can be fitted onto the slider fixing member 2134 for fixation.

[0085] For details, please refer to Figure 6 The airflow regulating device 21 also includes a cigarette clamp 215, in which the heated cigarette 1 is fixed.

[0086] For details, please refer to Figure 7 The cigarette clamp 215 includes a vent 2152. When smoking, the working airflow of the heated cigarette device 2 forms an airflow path from the air intake structure 212 to the vent 2152 and into the heating tube 22.

[0087] Specifically, the ventilation hole 2152 is located on the side wall of the cigarette clamp 215, and the working airflow flows through the ventilation hole 2152 along the side wall of the heating tube 22 to the bottom of the heated cigarette 1.

[0088] Specifically, the cigarette clamping component 215 includes a sealing port 2151 and a cigarette clamping rib 2153, with at least two cigarette clamping ribs 2153.

[0089] Specifically, the sealing opening 2151 and the cigarette clamping positions 2153 are arranged sequentially from top to bottom. The heated cigarette 1 passes through the sealing opening 2151 and the cigarette clamping positions 2153 and is fixed in the heating tube 22. More specifically, the cigarette clamping component 215 is fixed together with the outer shell 211 for the heated cigarette 1 to be inserted. The sealing opening 2151 on the upper part of the cigarette clamping component 215 is in complete contact with the outer wall of the heated cigarette 1. A vent hole 2152 is provided on the side wall of the cigarette clamping component 215. Four cigarette clamping positions 2153 are provided inside the lower part of the cigarette clamping component 2155, and the heated cigarette 1 is fixed by the cigarette clamping positions 2153.

[0090] Specifically, the heated tobacco device 2 also includes conventional tobacco device structures such as a heating element, a control circuit 23, and a battery cell 24. Existing tobacco device structures and connections can be incorporated into this patent. The heating element provides a specific heating temperature to the tobacco shreds of the heated cigarette 1, and its heating method can be internal heating or circumferential heating.

[0091] For example, the heating scheme related to the inner core heating can refer to the technical content disclosed in Chinese Patent Publication No. CN222787088U. The heating element is used to heat the cigarette inserted into the heated tobacco device, including a heating inner core and an airflow heating element. The airflow heating element is placed between the airflow channel of the heated tobacco device and the cigarette, and has a vent hole to connect the airflow channel and the cigarette. The heating inner core is located in the middle of the airflow heating element and has an extension that extends out of the airflow heating element. The extension is used to heat the tobacco in the cigarette. After the heating inner core heats up, it can transfer heat to the airflow heating element, causing the temperature of the airflow heating element to rise. This allows the external air flowing through the vent hole after inhalation to be heated, and then flows to the tobacco in the cigarette to heat the tobacco. Preferably, the heating inner core and the airflow heating element are independent components, and the heating inner core is fixed in the middle of the airflow heating element. Preferably, the airflow heating element has a fixing hole in the middle, and the heating inner core is tightly embedded in the fixing hole. Preferably, the fixing hole is a through hole, and the heating inner core extends longitudinally through the entire airflow heating element. Preferably, the airflow heating element is made of a material with high thermal conductivity and high heat capacity. Preferably, the length of the protrusion is less than or equal to half the length of the tobacco segment of the cigarette. Preferably, the airflow heating element has multiple ventilation holes, each ventilation hole being arranged around the heating core. Preferably, the ventilation holes are arranged in a honeycomb pattern.

[0092] For example, the relevant heating scheme for circumferential heating can be found in the technical content disclosed in Chinese Patent Publication No. CN208597720U. The heating element is an induction heating element, which includes an induction coil and a heating element disposed on the outer wall of the heating cavity. The electronic control system is used to convert the electrical energy provided by the power supply into a high-frequency induced current and then provide it to the induction coil. The high-frequency induced current in the induction coil generates an alternating magnetic field with a constantly changing direction, causing eddy currents to appear in the heating element located in the alternating magnetic field and thus raising its temperature, thereby heating the tobacco segment in the heating cavity. In this embodiment, the heating element includes a heating base disposed on the bottom wall of the heating cavity and a circumferential inner wall of the heating cavity. The induction coil includes a bottom induction coil disposed on the outside of the heating base and a circumferential wall induction coil disposed on the outside of the circumferential inner wall of the heating cavity.

[0093] More specifically, the control circuit 23 is used to control the input power of the heating element.

[0094] More specifically, cell 24 is used to provide power for the entire system.

[0095] The airflow path of the heated cigarette device 2 during inhalation is as follows: it enters from the airflow regulating device 21, passes through the air vent 2152 on the side of the cigarette clamp 215 along the inside of the outer shell 211, then along the outer wall of the heated cigarette 1 to the bottom of the cigarette, and is finally inhaled into the consumer's mouth. When the sliding component 213 covers the area of ​​the closed air intake structure 212, the entire air passage is completely blocked.

[0096] The working principle of this patent can be found by referring to... Figures 8A-8D ,like Figure 8A As shown, the airflow regulating device 21 is in the first use state, at which time the suction has not started or is in the preheating stage of suction, and the air intake structure 212 is completely closed and covered by the sliding component 213.

[0097] like Figure 8B As shown, the airflow regulating device 21 is in the second use state, at which time it is ready to suck. The consumer can push the sliding cover 2131 to the left to adjust the coverage area of ​​the air intake structure 212 to increase the air intake flow.

[0098] like Figure 8C As shown, the airflow regulating device 21 is in the third operating state. As the sliding cover 2131 moves to the left, the area covered by the sliding component 213 of the air intake structure 212 is reduced, and part of the air intake structure 212 is opened and released to face the outside directly, thereby increasing the air intake flow.

[0099] like Figure 8DAs shown, the airflow regulating device 21 is in the fourth operating state. The sliding cover 2131 is moved to the left to the threshold position. At this time, the air intake structure 212 is completely detached from the cover of the sliding component 213 and is fully opened and released to face the outside directly. The air intake flow rate increases to the maximum value.
