Description

Technical Field

[0001] This utility model relates to the field of smoking accessories, and in particular to heated cigarette smoking accessories. Background Technology

[0002] Heated cigarettes are a type of novel tobacco product. They work by electrically heating the cigarette at a low temperature, producing smoke without combustion. Current heated cigarette devices have a large heat source area, easily generating high aerosol temperatures. After prolonged use, residual aerosol condenses inside the device, gradually accumulating into tar, which is difficult to clean and repeatedly heated, releasing unwanted substances. Furthermore, when users smoke multiple cigarettes consecutively, the high residual temperature inside the device after the initial use leads to even higher aerosol temperatures with subsequent use, resulting in a different smoking experience compared to the initial use.

[0003] To address this, existing technology provides an electronic atomizing device equipped with an airflow generating mechanism to blow external gas into an insertion channel for holding the cigarette. Before the user inhales, the airflow generating mechanism is activated, creating an airflow to expel the high-temperature smoke and aerosol from the heated non-combustible cigarette. However, a problem with this device is that the airflow channel is curved, resulting in significant gas flow resistance. Utility Model Content

[0012] As a preferred embodiment of heated cigarette devices, a sealing ring is provided between the outer wall of the convection mounting bracket and the inner wall of the mounting groove.

[0013] As a preferred embodiment of heated cigarette devices, a heat-insulating support is also included, one end of which is connected to the mounting cylinder, and the other end is sleeved on the outer wall of the convection mounting frame.

[0014] As a preferred embodiment of heated cigarette devices, the heat-insulating support member has a first end for connecting the mounting cylinder, a second end for fitting onto the outer wall of the convection mounting bracket, and an intermediate section located between the first end and the second end, wherein the cross-sectional area of ​​the intermediate section is smaller than the cross-sectional area of ​​the second end.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a heated cigarette device, including a shell, a heating element, and an enhanced convection device. The shell has a receiving cavity for accommodating a cigarette and an airflow channel communicating with the receiving cavity. The shell also has an air inlet communicating with the airflow channel, which allows external gas to enter. When the user inhales or when the enhanced convection device is activated, external gas can enter the receiving cavity from the air inlet and the airflow channel to replenish it.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] After prolonged use, heated cigarette devices are prone to condensation and buildup of residual aerosol inside, gradually forming e-liquid that is difficult to clean and repeatedly heated, releasing unwanted substances. Furthermore, when users smoke multiple cigarettes consecutively, the high residual temperature inside the device after the initial use can generate even higher-temperature aerosols with subsequent use, resulting in a different smoking experience compared to the initial use. To address this, existing technology provides an electronic atomizing device with an airflow generator that directs external gas into an insertion channel for the cigarette. Before the user inhales, the airflow generator activates, creating an airflow to expel the high-temperature smoke from the heated cigarette. However, a problem with this device is that the airflow channel is curved, resulting in significant airflow resistance.

[0036] In response, this embodiment provides a heated cigarette smoking device to solve the problem in the prior art where the airflow channel for gas passage is bent, resulting in high gas flow resistance. This device can be used in the field of smoking device technology.

[0037] Reference Figures 1-3 The heated cigarette device includes a housing 1, a heating element 2, and a convection enhancer 3. The housing 1 has a receiving cavity 11 for accommodating a cigarette 100 and an airflow channel 12 communicating with the receiving cavity 11. The housing 1 also has an air inlet 13 communicating with the airflow channel 12. The air inlet 13 allows external gas to enter, so that when the user inhales or when the convection enhancer 3 is activated, external gas can enter the receiving cavity 11 from the air inlet 13 and the airflow channel 12 to replenish it. The centerlines of the receiving cavity 11, the airflow channel 12, and the air inlet 13 coincide, so that the flow direction of the gas in the airflow channel 12 is consistent with the flow direction of the gas in the receiving cavity 11, thereby reducing the resistance encountered by the gas during flow. The heating element 2 generates heat and is used to heat the cigarette 100 placed in the receiving cavity 11, so that the cigarette 100 is heated to produce smoke. The user inhales the gas in the receiving cavity 11 into their body by inhaling. The enhanced convection device 3 is installed in the airflow channel 12 and is used to blow gas into the receiving cavity 11. This allows the high-temperature gas and unwanted aerosols in the receiving cavity 11 to be blown out before the user inhales, making the smoke purer. In addition, during the inhalation process, fresh air can be blown into the receiving cavity 11 through the enhanced convection device 3 to facilitate gas circulation and avoid local overheating that could lead to the generation of unwanted substances.

[0038] Continue to refer to Figures 1-3 The housing 1 includes an outer shell 14 and a mounting cylinder 15 disposed on the outer shell 14. The mounting cylinder 15 is made of a heat-conducting material. The receiving cavity 11 is located inside the mounting cylinder 15. The heating element 2 is sleeved on the outer wall of the mounting cylinder 15, so that the heat emitted by the heating element 2 can enter the receiving cavity 11 through the outer wall of the mounting cylinder 15 to heat the cigarette 100.

[0039] Optionally, the heating element 2 is mesh-like and covers the outer wall of the mounting cylinder 15, thereby transferring heat to the mounting cylinder 15. Further, two heating elements 2 are provided, spaced apart along the length of the mounting cylinder 15, thereby uniformly heating the mounting cylinder 15.

[0040] Continue to refer to Figures 1-3 The housing 1 also includes a convection mount 16, with the enhanced convection 3 disposed in the inner cavity 161 of the convection mount 16. The outer shell 14 has a mounting groove 141, which communicates with the air inlet 13. The convection mount 16 is inserted into the mounting groove 141, and the mounting groove 141 and the inner cavity 161 of the convection mount 16 together form an airflow channel 12. After the gas enters the mounting groove 141 through the air inlet 13, it enters the enhanced convection 3 through the inner cavity 161 of the convection mount 16. By inserting the convection mount 16 into the mounting groove 141, the convection mount 16 and the outer shell 14 are detachably connected, facilitating their assembly or disassembly.

[0041] Continue to refer to Figures 1-3 In order to improve the sealing effect between the outer wall of the convection mounting bracket 16 and the inner wall of the mounting groove 141 and prevent air leakage, a sealing ring 162 is provided between the outer wall of the convection mounting bracket 16 and the inner wall of the mounting groove 141.

[0042] Continue to refer to Figures 1-3 The heated cigarette device also includes a heat-insulating support 6. One end of the heat-insulating support 6 is connected to the mounting cylinder 15, and the other end is sleeved on the outer wall of the convection mounting frame 16. The heat-insulating support 6 further fixes the relative position between the mounting cylinder 15 and the convection mounting frame 16, and prevents the heat from the mounting cylinder 15 from being transferred to the convection mounting frame 16, thereby preventing the heat from being transferred to the enhanced convection 3.

[0043] Continue to refer to Figures 1-3The heat-insulating support 6 has a first end 61 for connecting to the mounting cylinder 15, a second end 62 for fitting onto the outer wall of the convection mounting bracket 16, and an intermediate section 63 located between the first end 61 and the second end 62. The cross-sectional area of ​​the intermediate section 63 is smaller than that of the second end 62. This arrangement enhances the flow rate and reduces the pressure of the airflow generated by the convection 3 as it passes through the intermediate section 63, thus concentrating the airflow. Optionally, the transition portion between the second end 62 and the intermediate section 63 is funnel-shaped, with a larger cross-sectional area near the second end 62 and a smaller cross-sectional area near the intermediate section 63. Since the first end 61 is connected to the mounting cylinder 15, its cross-sectional area should be compatible with that of the mounting cylinder 15. In this embodiment, the cross-sectional area of ​​the first end 61 is larger than that of the intermediate section 63 to prevent the cigarette 100 from entering the intermediate section 63. In other embodiments, the cross-sectional area of ​​the first end 61 may be smaller than that of the intermediate section 63, or the two cross-sectional areas may be the same.

[0044] Continue to refer to Figures 1-3 The gas from the air inlet 13 can only enter the receiving cavity 11 through the enhanced convection device 3, so that there is only one airflow channel 12, and the gas can only flow through the airflow channel 12 and through the enhanced convection device 3, thereby simplifying the overall structure of the heated cigarette device.

[0045] In some embodiments, the cross-sectional area of ​​the air inlet 13 is smaller than the cross-sectional area of ​​the narrowest point of the airflow channel 12. In this embodiment, since the convection mount 16 is inserted into the mounting groove 141, the narrowest point of the airflow channel 12 is generally located in the inner cavity 161 of the convection mount 16. By reducing the cross-sectional area of ​​the air inlet 13, some dust or impurities can be blocked, preventing them from entering the airflow channel 12 in large quantities. In addition, the appearance of the heated cigarette device can be made more aesthetically pleasing.

[0046] Continue to refer to Figures 1-3 The enhanced convection device 3 is specifically one of a fan, blower, compressor, or vacuum pump, all of which can blow external gas into the receiving cavity 11. Furthermore, the airflow velocity generated by the enhanced convection device 3 is 0.1–3.0 m / s to meet the gas flow requirements within the receiving cavity 11.

[0047] Continue to refer to Figures 1-3 The heated cigarette device also includes a power supply 4 disposed in the housing 1. The power supply 4 is used to supply power to the heating element 2 and the enhanced convection device 3. In this embodiment, the power supply 4 is a battery. The mounting cylinder 15 and the convection device mounting bracket 16 are disposed on one side inside the housing 1, and the battery is disposed on the other side inside the housing 1.

[0048] Continue to refer to Figures 1-3The heated cigarette device also includes a control element 5, which is electrically connected to a power supply 4. The heating element 2 and the enhanced convection device 3 are both communicatively connected to the control element 5. The power supply 4 can supply power to the control element 5, and the control element 5 can control the heating element 2 to open or close, so that the heating element 2 heats or stops heating the cigarette 100 in the receiving cavity 11. The control element 5 can also control the enhanced convection device 3 to open or close, so that the enhanced convection device 3 blows external gas into the receiving cavity 11 or stops blowing gas.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
