Description

Technical Field

[0001] This invention relates to the field of heated cigarette technology, and more particularly to a heated cigarette device. Background Technology

[0002] Heated cigarettes are a new type of tobacco product. Their working principle involves using a special device to heat the cigarette at a low temperature. Without open flame combustion, the nicotine and aroma compounds in the tobacco evaporate, forming an aerosol for the consumer to inhale. Compared to traditional open-flame cigarettes, heated cigarettes must be used with a heating device. The heating element inside the device provides the heat source to heat the inserted cigarette. Heated cigarettes significantly reduce the formation of combustion byproducts such as tar and carbon monoxide, and their market penetration rate is increasing year by year.

[0003] Current heated cigarette devices on the market mainly achieve different flavors by setting a rotating flavoring disc. However, they usually only have a single airflow channel. Flavorings of different types all converge into the same main airflow path. Unselected flavoring units are prone to cross-contamination due to natural evaporation, which destroys the flavor purity of each type. In addition, current heated cigarette devices only support switching flavors when changing cigarettes, and cannot switch flavors while smoking a single cigarette, which affects the user experience.

[0022] Figure 1 This is a schematic diagram of the structure of a heated cigarette smoking device provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of another heated cigarette device provided in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the heated cigarette device includes: a casing 10, a heating element 20, multiple airflow channels 30, and at least one air inlet 40; the heating element 20 and each airflow channel 30 are located inside the casing 10, and the air inlet 40 is disposed on the casing 10; the air inlet 40 communicates with the external environment; the casing 10 includes a cigarette receiving cavity A, which includes a cigarette insertion port B and a gas inlet C; the heated cigarette to be heated is inserted into the cigarette receiving cavity A through the cigarette insertion port B; the heating element 20 is at least partially disposed around the cigarette receiving cavity A, and the heating element 20 is used to heat the heated cigarette to be heated; one end of each airflow channel 30 is selectively connected to the air inlet 40, and the other end of each airflow channel 30 is connected to the gas inlet C; the airflow channels 30 are used to place flavorings; the heated cigarette device also includes: a channel selection module (not shown in the figure), which is connected to the multiple airflow channels 30.

[0023] Among them, the heated cigarette device is a tool used to heat the cigarette. The user can insert the cigarette to be heated into the cigarette receiving cavity A of the outer shell 10 of the device through the cigarette insertion port B, and control the heating component 20 to heat the cigarette. The heating component 20 can be set inside or outside the cigarette receiving cavity A. The nicotine in the tobacco evaporates when heated and forms an aerosol. The user inhales the heated cigarette to achieve the smoking experience.

[0024] The heated cigarette device also includes at least one air inlet 40 and multiple airflow channels 30. Each airflow channel 30 is independently sealed. Outside air can enter the airflow channel 30 through the air inlet 40. Flavoring is placed inside the airflow channel 30. When the user smokes, the air comes into contact with the flavoring in the airflow channel 30 and carries the aroma components released by the flavoring. The aroma mixes with the smoke generated by the heated cigarette and enters the user's mouth. The number of airflow channels 30 and air inlets 40 can be arbitrary; this embodiment of the invention does not specifically limit this. This embodiment of the invention provides an example of a heated cigarette device including three airflow channels 30 and three air inlets 40.

[0025] The heated cigarette device also includes a channel selection module, which is connected to multiple airflow channels 30. The channel selection module is used to control the conduction state of each airflow channel 30. Users can select different airflow channels 30 through the channel selection module to allow air to come into contact with the flavorings in that airflow channel 30. Unselected airflow channels 30 are in a closed state to prevent airflow from coming into contact with different flavorings and avoid the risk of flavor mixing. Users can also change the conduction state of each airflow channel 30 through the channel selection module during smoking to switch between different flavors and improve the user experience.

[0026] This embodiment sets up multiple airflow channels inside the heated cigarette device and places flavorings inside the airflow channels to meet the user's multi-flavor smoking needs. The channel selection module controls the conduction state of each airflow channel, allowing the user to freely switch airflow channels at different smoking stages. This enables the user to switch between different flavors during smoking, avoids the risk of flavor mixing, and improves the user experience.

[0027] Optionally, the channel selection module includes: a channel selection switch 50 and a control valve assembly 60; the smoking device housing 10 is provided with multiple air inlets 40 corresponding one-to-one with the airflow channels 30, the channel selection switch 50 is disposed on the smoking device housing 10, and the control valve assembly 60 is disposed between each airflow channel 30 and the air inlet 40, and the control valve assembly 60 is connected to the channel selection switch 50; the channel selection switch 50 is used to control the conduction state of the control valve assembly 60.

[0028] The control valve assembly 60 is used to control the connection state between each airflow channel 30 and the air inlet 40. The channel selection switch 50 is connected to the control valve assembly 60. The user can manually operate the channel selection switch to control the conduction state of the control valve assembly 60, thereby making one airflow channel 30 conduct.

[0029] Optionally, the control valve assembly 60 includes a rotary control valve; the rotary control valve includes at least one valve disc 61 and a rotating disk 62, the at least one valve disc 61 being fixed to the rotating disk 62; the rotating disk 62 drives the valve disc 61 to rotate, so that the at least one valve disc 61 controls one airflow passage 30 to communicate with the air inlet 40, and controls other airflow passages 30 to disconnect from the air inlet 40.

[0030] The rotating disk 62 can drive the valve plate 61 to rotate, thereby changing the conduction state of each airflow channel 30. When the valve plate 61 controls one airflow channel 30 to be connected to the air inlet 40, air can flow through the airflow channel 30. The air comes into contact with the fragrance in the airflow channel 30 and carries the fragrance components released by the fragrance. The fragrance mixes with the smoke generated by the heated cigarette and enters the user's mouth. At the same time, the valve plate 61 can control other airflow channels 30 to be disconnected from the air inlet 40, and air cannot flow through the airflow channel 30.

[0031] In an exemplary embodiment, the valve plate 61 may be a strip-shaped valve plate, and the valve plate 61 is correspondingly arranged with the airflow channel 30. The rotating disk 62 can drive the valve plate 61 to rotate, so as to change the conduction state of each airflow channel 30.

[0032] In one exemplary embodiment, when the rotary control valve includes two valve discs 61, each valve disc 61 is connected to form a blocking assembly with a notch. Figure 3 This is a schematic diagram of the structure of a rotary control valve provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the blocking component includes a 2 / 3 blocking area and a 1 / 3 unblocked area. The rotating disk 62 drives the blocking component to rotate, changing the conduction state of each airflow channel 30. When an airflow channel 30 is opposite to the blocking area of ​​the blocking component, air cannot flow through it; when an airflow channel 30 is opposite to the unblocked area of ​​the blocking component, air can flow through it. The air comes into contact with the fragrance within the airflow channel 30 and carries the aroma components released by the fragrance. The aroma mixes with the smoke generated by the heated cigarette and enters the user's mouth.

[0033] Optionally, the channel selection switch 50 includes a rotary channel selection switch; the rotary channel selection switch is connected to the rotary disk 62 via a rotating spindle.

[0034] The rotary channel selector switch is connected to the rotating disk 62 via a rotating spindle. When the user rotates the rotary channel selector switch, the rotating spindle drives the rotating disk 62 to rotate, thereby changing the blocking position of the blocking component relative to each airflow channel 30. For example, when the heated cigarette device includes three airflow channels 30 and two valve plates 61, the user can switch between different airflow channels 30 by rotating the rotary channel selector switch by 120° to meet the user's different smoking needs.

[0035] Optionally, the control valve assembly 60 includes a plurality of on / off control valves corresponding one-to-one with the plurality of airflow channels 30; each on / off control valve is correspondingly disposed between each airflow channel 30 and the air inlet 40.

[0036] Each airflow channel 30 is equipped with an independent on / off control valve, which can be a solenoid valve. The on / off control valve has two working states: open and closed. When the on / off control valve is in the open state, air can flow through the airflow channel 30; when the on / off control valve is in the closed state, air cannot flow through the airflow channel 30. At most one of the multiple on / off control valves can be in the open state to avoid cross-contamination of flavors between different spices.

[0037] Optionally, the channel selection switch 50 includes a toggle channel selection switch; the toggle channel selection switch includes multiple position keys corresponding to the airflow channels 30, and the heated cigarette device also includes multiple linkages and paddles corresponding to the airflow channels 30. The multiple linkages are respectively connected to the multiple position keys of the toggle channel selection switch, and the multiple paddles are respectively connected between the multiple linkages and the multiple on / off control valves.

[0038] The toggle channel selector switch includes multiple gear keys corresponding to the airflow channel 30. Each gear key corresponds to a different on / off control valve. When the user moves the toggle channel selector switch to a certain gear key position, the gear key drives the corresponding linkage to move. The linkage further drives the paddle to move, thereby switching the on / off control valve connected to the paddle to the open state.

[0039] Optionally, the heated cigarette device also includes: a controller 70; a channel selection switch 50 including a push-button channel selection switch; the controller 70 is connected to the push-button channel selection switch and each on / off control valve respectively; the controller 70 is used to receive operation commands through the push-button channel selection switch and control the conduction state of each on / off control valve according to the operation commands.

[0040] Specifically, the push-button channel selector switch includes multiple buttons. Users can press different buttons to change the operating state of each on / off control valve. The controller 70 can receive operation commands through the push-button channel selector switch and control the conduction state of each on / off control valve according to the operation commands.

[0041] Optionally, different flavorings can be placed in different airflow channels 30 to meet the user's personalized smoking needs. For example, the flavoring can be tobacco flavoring to give the user a pure tobacco aroma; the flavoring can be fruit flavoring to give the user a fruity flavor; or the flavoring can be mint flavoring to give the user a refreshing flavor.

[0042] Optional, continue to refer to Figure 2 The heated cigarette device also includes a controller 70; the controller 70 is connected to the channel selection switch 50 and the heating component 20 respectively; the controller 70 is used to control the heating power of the heating component 20 according to the state of the channel selection switch 50; wherein, the heating power of the heating component 20 is different when different airflow channels 30 are open.

[0043] Specifically, the controller 70 can determine the airflow channel 30 through which the air is flowing at the current moment based on the state of the channel selection switch 50, and then control the heating component 20 to heat the cigarette with different heating power according to the type of fragrance in the airflow channel 30, thereby improving the user's smoking experience.

[0044] For example, when the channel selection switch 50 controls the airflow channel 30 containing mint flavoring to be turned on, the heating power of the heating component 20 can be increased because the cooling sensation of mint flavor is strong, so that the higher temperature smoke can neutralize the mint flavor; when the channel selection switch 50 controls the airflow channel 30 containing fruit flavoring to be turned on, the heating power of the heating component 20 can be reduced because fruit flavor is prone to flavor deterioration at high temperatures, thus improving the user's smoking experience.

[0045] Optionally, the heated cigarette device also includes: a power supply module (not shown in the figure); the power supply module is connected to the heating component 20; the power supply module is used to supply power to the heating component 20 to improve the power supply stability of the heated cigarette device.
