Description

Technical Field

[0001] This utility model relates to the field of aerosol delivery technology, and in particular to an aerosol delivery device. Background Technology

[0002] Currently, aerosol delivery devices can heat heated non-combustible products (such as non-combustible tobacco products) at relatively low temperatures (e.g., 250℃~500℃), thereby releasing a tobacco-flavored aerosol and delivering it to the consumer without combustion, thus replacing combustible tobacco products. In existing technology, heated non-combustible products have a filter section for contact with the lips for inhalation. However, when heated by an aerosol delivery device, the temperature can reach over 300℃. If a large amount of heat is transferred to the filter section, the filter section will become too hot, causing burns to the user's mouth and negatively impacting the user experience. Summary of the Invention

[0003] To overcome the problems of burns caused by high filter temperature in existing aerosol delivery devices when heating non-combustible products, this invention provides an aerosol delivery device.

[0004] In view of the above technical problems, this utility model provides an aerosol delivery device, comprising:

[0005] The heat-insulating tube is equipped with an interface for inserting heated non-combustible products;

[0006] A fixed tube having an upstream end, a downstream end, and a receiving cavity located between the upstream and downstream ends, the receiving cavity being used to receive at least a portion of a heated non-combustible article;

[0007] The fixed tube is supported and fixed inside the heat insulation tube to form an airflow channel between the fixed tube and the heat insulation tube. The top of the fixed tube abuts against the heat insulation tube, and the downstream of the receiving cavity is connected to the insertion port. The radial radius d1 of at least a portion of the insertion port is greater than the radial radius d2 of the receiving cavity. A first connecting channel is opened on the fixed tube near the downstream position. The insertion port is connected to the airflow channel through the first connecting channel. The upstream of the receiving cavity is connected to the airflow channel.

[0008] The heating element is supported and fixed inside the heat insulation tube. External airflow flows through the plug interface, the first connecting channel and the airflow channel to the heating element and raises its temperature.

[0009] In this invention, when the user uses the product, they insert the heated non-combustible product into the receiving cavity through the insertion port. Because the radial radius d1 of at least a portion of the insertion port is greater than the radial radius d2 of the receiving cavity, a gap exists between the inserted heated non-combustible product and the insertion port. When the user inhales through the heated non-combustible product, external gas flows through the insertion port, the first connecting channel, and the airflow channel to the heater, where its temperature is raised. The heated gas is then used to bake the heated non-combustible product to generate an aerosol for the user to inhale. Since the external gas temperature is relatively low, some of the heat from the heated non-combustible product is carried away during its flow. This preheats the external gas and reduces the heat transferred to the user's mouth, preventing burns and improving the user experience. Attached Figure Description

[0017] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] like Figures 1 to 4As shown, this embodiment of the present invention provides an aerosol delivery device, comprising:

[0019] The heat insulation tube 100 is provided with an insertion interface 110 for inserting the heated non-combustible product 700.

[0020] The fixed tube 200 has an upstream end, a downstream end, and a receiving cavity 210 located between the upstream and downstream ends, the receiving cavity 210 being used to receive at least a portion of the heated non-combustible article 700.

[0021] The fixed tube 200 is supported and fixed inside the heat insulation tube 100, so that an airflow channel 300 is formed between the fixed tube 200 and the heat insulation tube 100. The top of the fixed tube 200 abuts against the heat insulation tube 100, and the downstream of the receiving cavity 210 is connected to the insertion port 110. The radial radius d1 of at least a portion of the insertion port 110 is greater than the radial radius d2 of the receiving cavity 210. A first connecting channel 220 is opened on the fixed tube 200 near the downstream position. The insertion port 110 is connected to the airflow channel 300 through the first connecting channel 220. The upstream of the receiving cavity 210 is connected to the airflow channel 300.

[0022] The heater 400 is supported and fixed inside the heat insulation tube 100. External airflow flows through the plug interface 110, the first connecting channel 220 and the airflow channel 300 to the heater 400 and the temperature is raised.

[0023] Understandably, "upstream" or "downstream" refers to the upstream or downstream direction of the airflow or aerosol flow. Since the radial radius d1 of at least a portion of the insertion port 110 is greater than the radial radius d2 of the receiving cavity 210, a gap is formed between the insertion port 110 and the heated non-combustible product 700 after the insertion port 110 is inserted, thus forming a notch 120 adjacent to the heated non-combustible product 700 and used to connect to the outside. Simultaneously, after the heated non-combustible product 700 is inserted into the insertion port 110, the upstream of the heated non-combustible product 700 is connected to the downstream of the fixed tube 200. When the user draws air through the downstream of the heated non-combustible product 700, air enters the airflow channel 300 from the notch 120 through the first connecting channel 220, is then heated by the heater 400, and finally enters the heated non-combustible product 700 through the fixed tube 200 to bake the heated non-combustible product 700, thereby generating an aerosol for the user to draw in. In addition to connecting the insertion port 110 and the airflow channel 300, the first connecting channel 220 can also reduce the contact area between the fixing tube 200 and the heat insulation tube 100, thereby reducing the heat transferred from the fixing tube 200 to the heat insulation tube 100, preventing the heat insulation tube 100 from overheating, and further avoiding the problem of scalding the user's mouth when sucking.

[0024] In this embodiment, when the user uses the heated non-combustible product 700, it is inserted into the receiving cavity 210 through the insertion port 110. Since the radial radius d1 of at least a portion of the insertion port 110 is greater than the radial radius d2 of the receiving cavity 210, a gap exists between the inserted heated non-combustible product 700 and the insertion port 110. When the user inhales through the heated non-combustible product 700, external gas flows through the insertion port 110, the first connecting channel 220, and the airflow channel 300 to the heater 400, where its temperature is raised. The heated gas is used to bake the heated non-combustible product 700 to generate an aerosol for the user to inhale. Because the external gas temperature is relatively low, some of the heat from the heated non-combustible product 700 is carried away during its flow. This preheats the external gas and reduces the heat transferred to the user's mouth, preventing burns and improving the user experience.

[0025] In one embodiment, such as Figure 3 As shown, the radial radius d3 of another portion of the insertion interface 110 is equal to the radial radius d2 of the receiving cavity 210. It can be understood that the insertion interface 110 and the receiving cavity 210 are correspondingly arranged, so that the heat-not-burning article 700 can be inserted into the receiving cavity 210 through the insertion interface 110. The radial radius d3 of the other portion of the insertion interface 110 and the radial radius d2 of the receiving cavity 210 can be equal to or slightly larger than the outer diameter of the heat-not-burning article 700, thereby facilitating the insertion of the heat-not-burning article 700.

[0026] In one embodiment, such as Figure 2 and Figure 3 As shown, the heater 400 is supported and fixed within the fixed tube 200 and located between the airflow channel 300 and the receiving cavity 210. It can be understood that the upstream of the receiving cavity 210 communicates with the airflow channel 300; therefore, by placing the heater 400 between the airflow channel 300 and the receiving cavity 210, it is convenient to heat the airflow flowing between the airflow channel 300 and the receiving cavity 210.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the heater 400 is provided with an air outlet 410 for connecting the receiving cavity 210, a connecting hole 420 for connecting the airflow channel 300, and a heating cavity 430 for heating air to bake the heated non-combustible product 700, which is connected between the air outlet 410 and the connecting hole 420.

[0028] In one embodiment, such as Figure 2 and Figure 3 As shown, the bottom of the fixed tube 200 abuts against the heat insulation tube 100. A second connecting channel 230 is provided on the fixed tube 200 near the upstream position. The upstream of the receiving cavity 210 is connected to the airflow channel 300 through the second connecting channel 230. It can be understood that the shape of the second connecting port can be set according to the actual situation, as long as it can connect the airflow channel 300 and the receiving cavity 210.

[0029] In one embodiment, such as Figure 3 As shown, a limiting ring 240 is provided upstream of the receiving cavity 210. The radial radius d4 of the inner ring of the limiting ring 240 is smaller than the radial radius d2 of the receiving cavity 210. The upper end of the heater 400 abuts against the limiting ring 240. Understandably, the limiting ring 240 has a certain thickness, which can restrict the lowest insertion position of the heat-not-burning product 700 in the receiving cavity 210, preventing the heat-not-burning product 700 from directly contacting the heater 400. This allows the heater 400 to evenly transfer heat upwards to the heat-not-burning product 700, thereby improving overall heating efficiency. Simultaneously, it can also connect upstream of the heat-not-burning product 700, ensuring that the air heated by the heater 400 enters the receiving cavity 210 through the inner ring of the limiting ring 240, thus concentrating heating on the central position of the heat-not-burning product 700 and preventing excessively high temperatures at the periphery of the product, which could lead to discoloration.

[0030] In one embodiment, such as Figure 2 and Figure 3 As shown, the lower end of the fixing tube 200 is provided with a limiting protrusion 250, and the lower end of the heater 400 abuts against the limiting protrusion 250. It can be understood that the upper end of the heater 400 abuts against the limiting ring 240, and the lower end of the heater 400 abuts against the limiting protrusion 250, thereby completing the fixed installation of the heater 400 in the fixing tube 200.

[0031] In one embodiment, such as Figure 3 As shown, the inner wall of the receiving cavity 210 is provided with an insertion ring 260. When the heatless non-combustible product 700 is inserted into the receiving cavity 210, the insertion ring 260 abuts against the outer wall of the heatless non-combustible product 700. Understandably, after the heatless non-combustible product 700 is inserted into the receiving cavity 210, the inner ring surface of the insertion ring 260 abuts against the outer wall of the heatless non-combustible product 700, thereby reducing the contact area between the fixing tube 200 and the heatless non-combustible product 700, thus reducing heat transfer between them, and preventing gaps between the heatless non-combustible product 700 and the receiving cavity 210. The shape of the insertion ring 260 can be set according to actual conditions, as long as it can abut against the outer wall of the heatless non-combustible product 700, thereby reducing the contact area between the fixing tube 200 and the heatless non-combustible product 700.

[0032] In one embodiment, such as Figures 1 to 3 As shown, the aerosol delivery device also includes a housing 500, which has an opening 510 for inserting a heated non-combustible article 700. Understandably, the housing 500 prevents dust or debris from entering the interior, and it also allows the user to hold the device, preventing burns during use.

[0033] In one embodiment, such as Figure 3 As shown, the aerosol delivery device also includes a power supply 600 disposed within the housing 500 and used to provide energy to the heater 400.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
