Description

Technical Field

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

[0002] Currently, heating heated non-combustible products (such as non-combustible tobacco products) at lower temperatures allows them to release aerosols that are transferred to consumers without combustion, thus replacing combustible tobacco products. In existing technologies, to ensure stable operation, the heater is typically fixed in place by a fixed structure. Thus, when the heater heats the heated non-combustible product, the heat generated is conducted outwards through the fixed structure, resulting in significant heat loss, reduced heating efficiency, and potential damage or malfunction to internal electronic components. Summary of the Invention

[0003] To overcome the technical problems of large heat loss in existing aerosol heating schemes, this utility model provides an aerosol delivery device.

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

[0005] A heat insulation tube has an air cavity with an opening on one side and a closed end opposite to the opening. A first step is provided on the inner side of the heat insulation tube near the opening.

[0006] A fastener has a receiving cavity communicating with the opening, the receiving cavity being used to receive at least a portion of a heat-resistant non-combustible article, the fastener extending from the opening into the air cavity and abutting against the first step, such that a gap is created between the portion of the fastener extending into the air cavity and the closed end;

[0007] A heating element, mounted on the fixture, is used to increase the temperature of the flowing gas to heat the heat-non-combustible article.

[0008] Optionally, the fastener includes a first fixing tube, the first fixing tube being hollow to form the receiving cavity, the top of the first fixing tube extending radially outward to form a flange, the flange abutting against the first step, the flange having flange holes distributed on it, the flange holes communicating with the air cavity.

[0009] Optionally, the flange has an inner tube, an outer tube, and a connecting portion located between the inner tube and the outer tube, with flange holes distributed in the connecting portion.

[0010] Optionally, the heating assembly further includes a support cover, the outer periphery of which is mounted on the opening of the heat insulation tube, the central region of which extends to form a central channel communicating with the receiving cavity to jointly accommodate the inserted heat-resistant non-combustible article, the bottom of which abuts the top of the flange to form an air groove between the support cover, the heat insulation tube and the flange.

[0011] Optionally, the aerosol delivery device further includes a housing, the heating component is disposed in the housing, the housing is provided with an insertion port and a first air inlet, the insertion port communicating with the opening;

[0012] The support cover is provided with a second air inlet, which is connected to the first air inlet and the flange hole.

[0013] Optionally, the fastener further includes a second fixing tube, the top of which is connected to the bottom of the first fixing tube, and the gap is formed between the bottom of the second fixing tube and the closed end.

[0014] Optionally, the bottom of the first fixing tube is provided with a first insertion part, and the top of the second fixing tube is provided with a second insertion part. The first insertion part and the second insertion part are inserted into each other to form a fixing cavity for installing the heater between the first fixing tube and the second fixing tube.

[0017] The bottom of the second fixing tube is provided with a second support portion for supporting the heater.

[0018] Optionally, the inner wall of the first fixing tube is provided with an abutment portion, which abuts against the outer wall of the heater to form a heat insulation gap between the outer wall of the heater and the inner wall of the first fixing tube.

[0019] In the aerosol delivery device of the above embodiment of this utility model, the heater mounted on the fixing member is used to heat the heat-resistant non-combustible product in the receiving cavity to generate an aerosol for the user to inhale.

[0027] 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.

[0028] like Figures 1 to 3 As shown, this embodiment of the present invention provides an aerosol delivery device, including a heating component 1, which includes:

[0029] The heat insulation pipe 11 has an air cavity 111 with an opening 113 on one side and a closed end 112 opposite to the opening 113. A first step 114 is provided on the inner side of the heat insulation pipe 11 near the opening 113.

[0030] The fixing member 12 has a receiving cavity 121 with a communicating opening 113. The receiving cavity 121 is used to accommodate at least a portion of the heat-non-combustible article 2. The fixing member 12 extends from the opening 113 into the air cavity 111 and abuts against the first step 114, so that a gap 15 is created between the portion of the fixing member 12 extending into the air cavity 111 and the closed end 112. The air filled in the gap 15 has a good heat insulation effect, and the air barrier can reduce the direct downward transfer of heat from the heater 13 to the bottom of the closed end 112.

[0031] The heater 13, mounted on the fixture 12, is used to increase the temperature of the flowing gas to heat the non-combustible product 2. The heater 13 may also be provided with a heating chamber for air to pass through, thereby first heating the air in the heating chamber, and then using the heated air to bake the non-combustible product 2 in the receiving cavity 121 to generate an aerosol for the user to inhale.

[0032] In the aerosol delivery device of the above embodiment of this utility model, the heater 13 installed on the fixing member 12 is used to heat the heat-non-combustible product 2 in the receiving cavity 121 to generate aerosol for the user to inhale. The upper end of the fixing member 12 abuts against the first step 114 at the opening 113, and the lower end extends into the air cavity 111, so that a gap 15 is formed between the fixing member 12 and the closed end 112. In this way, the upper end of the fixing member 12 can be stably installed on the heat insulation tube 11, and the lower end of the fixing member 12 is suspended above the closed end 112. At this time, the heat conduction is blocked between the lower end of the heater 13 and the closed end 112 due to the gap 15, thus reducing the heat loss transmitted downward, so that the heater 13 concentrates the heat transfer upward to the heat-non-combustible product 2, reducing the heat conducted to the electronic components inside the device and causing damage, and also improving the heating effect of the heat-non-combustible product 2. At the same time, the heat insulation tube 11 also has a good heat insulation and heat preservation effect, improving the heating efficiency.

[0033] like Figures 1 to 4As shown, the fixing member 12 in this embodiment of the present invention includes a first fixing tube 122. The first fixing tube 122 is hollow to form a receiving cavity 121. The top of the first fixing tube 122 extends radially outward to form a flange 124. The flange 124 abuts against a first step 114. The flange 124 has flange holes 125 distributed on it, which communicate with the air cavity 111. Understandably, the first fixing tube 122 is securely installed on the top of the heat insulation tube 11 through the abutment of the flange 124 against the first step 114. Figure 1 As shown by the arrow, external gas enters the gas chamber 111 through the flange hole 125, and then the temperature is increased by the heater 13 to bake the heated non-combustible product 2 inserted into the receiving cavity 121, generating an aerosol for the user to inhale.

[0034] Furthermore, the flange 124 has an inner tube 1241, an outer tube 1242, and a connecting portion 1243 located between the inner tube 1241 and the outer tube 1242, with flange holes 125 distributed in the connecting portion 1243. The outer tube 1242 is coaxially arranged with the inner tube 1241.

[0035] Furthermore, the heating assembly 1 also includes a support cover 14, which is mounted on the outer periphery of the heat insulation pipe 11 at the opening 113. A central channel 141 extending from the central region of the support cover 14 forms a connecting cavity 121 to accommodate the inserted heat-resistant non-combustible product 2. The bottom of the central channel 141 abuts against the top of the flange 124, forming an air groove 4 between the support cover 14, the heat insulation pipe 11, and the flange 124. Further, a second step 1244 is formed at the connection between the inner pipe 1241 and the first fixing pipe 122. The lower end of the central channel 141 of the support cover 14 abuts against the second step 1244 for fixation. Specifically, the central channel 141 is inclined, and its inner diameter gradually decreases from top to bottom along its axial direction, thereby reducing the contact between the heat-resistant non-combustible product 2 and the support cover 14, and reducing the heat conducted to the heat-resistant non-combustible product 2.

[0036] Understandably, the gas groove 4 is arranged around the central channel 141. Since the heated non-combustible product 2 is inserted into the receiving cavity 121 through the central channel 141, when the heated non-combustible product 2 is heated, the position of the central channel 141 on the support cover 14 is in contact with the heated non-combustible product 2, and the temperature will also rise accordingly. At this time, the relatively low-temperature external gas enters the gas groove 4 arranged around the central channel 141, circulates in the gas groove 4 and fully contacts the support cover 14 to exchange heat, so that the temperature of the heated non-combustible product 2 located in the suction part inside the central channel 141 of the support cover 14 is reduced, avoiding burns to the user's mouth, and at the same time, the gas entering the gas cavity 111 from the gas groove 4 can be preheated.

[0037] like Figures 1 to 3 As shown, the aerosol delivery device also includes a housing 3, in which the heating component 1 is disposed. The housing 3 has an insertion port 31 and a first air inlet 32, the insertion port 31 being connected to the opening 113. The support cover 14 has a second air inlet 142, which is connected to the first air inlet 32 ​​and the flange hole 125. The heated non-combustible product 2 passes through the insertion port 31 and the central channel 141 and is then inserted into the receiving cavity 121. The housing 3 serves to protect the heating component 1 installed therein. Figure 1 As shown by the dashed arrows, external air enters the air chamber 111 sequentially through the first air inlet 32, the second air inlet 142, and the flange hole 125. The air is then heated by the heater 13 and ultimately used to bake the heated non-combustible product 2, generating an aerosol for the user to inhale. Understandably, the upper and lower ends of the support cover 14 abut against the outer shell 3 and the flange 124 respectively, and are stably installed in the heat insulation pipe 11 with the fastener 12.

[0038] like Figures 1 to 3 As shown, the fixing member 12 also includes a second fixing tube 123. The top of the second fixing tube 123 is connected to the bottom of the first fixing tube 122, and a gap 15 is formed between the bottom of the second fixing tube 123 and the closed end 112. In this embodiment, the first fixing tube 122 is securely installed on the top of the heat insulation tube 11 through the abutment of the flange 124 and the first step 114, while the second fixing tube 123 is detachably installed on the bottom of the first fixing tube 122. The bottom of the second mounting part is suspended above the bottom of the closed end 112 to form a gap 15. In this way, the second fixing tube 123 and the first fixing tube 122 are easy to assemble and disassemble, and the heater 13 is also easy to assemble and disassemble.

[0039] like Figures 4 to 6 As shown, the bottom of the first fixing tube 122 is provided with a first insertion portion 1221, and the top of the second fixing tube 123 is provided with a second insertion portion 1231. The first insertion portion 1221 and the second insertion portion 1231 are inserted into each other to form a fixing cavity 16 for mounting the heater 13 between the first fixing tube 122 and the second fixing tube 123. Specifically, the first insertion portion 1221 includes at least two insertion blocks spaced apart around the heater 133, such as... Figure 5 As shown, the first connector 1221 includes two connector blocks disposed opposite each other. The second connector 1231 includes at least two connector slots, such as... Figure 6 As shown, the second insertion part 1231 includes two insertion slots arranged opposite each other. Each insertion block is inserted into a corresponding insertion slot, so that the first insertion part 1221 and the second insertion part 1231 can be firmly inserted, thereby realizing the connection between the first fixing tube 122 and the second fixing tube 123.

[0040] like Figure 5As shown, a limiting part 126 is provided between the first fixing tube 122 and the second fixing tube 123. The limiting part 126 is arranged around the first fixing tube 122 to limit the insertion position of the first insertion part 1221 and the second insertion part 1231. Understandably, Figure 5 The limiting part 126 shown is a limiting step provided on the outer wall of the first fixing tube 122. In this utility model, the limiting part 126 can also be a slot or the like provided on the first fixing tube 122, as long as it can limit the insertion position between the first insertion part 1221 and the second insertion part 1231, thereby ensuring the accurate installation position between the first fixing tube 122 and the second fixing tube 123. In this embodiment, the limiting part 126 can also be a limiting step or a slot or the like provided on the second fixing tube 123, and is not limited here.

[0041] like Figures 4 to 5 As shown, a receiving cavity 121 is disposed on a first fixing tube 122. The first fixing tube 122 includes a first supporting portion 1222 disposed at the bottom of the receiving cavity 121 for supporting the heat-not-combustible article 2. The first supporting portion 1222 extends radially inward from the inner wall of the first fixing tube 122, and the fixing cavity 16 is located below the first supporting portion 1222. In this embodiment, the first supporting portion 1222 can be used to support the heat-not-combustible article 2 inserted into the receiving cavity 121, so that the heat-not-combustible article 2 is always securely installed in the receiving cavity 121.

[0042] like Figure 3 and Figure 6 As shown, the bottom of the second fixing tube 123 is provided with a second support portion 1232 for supporting the heater 13. The second support portion 1232 extends radially inward from the inner wall of the second fixing tube 123, and the fixing cavity 16 is located between the first support portion 1222 and the second support portion 1232. Figure 3 and Figure 6 In the embodiment shown, the bottom of the second fixing tube 123 is provided with a plurality of second support portions 1232. The plurality of second support portions 1232 are spaced apart and located on the same plane to support the heater 13 installed in the fixing cavity 16 and prevent the heater 13 from sliding out of the fixing cavity 16.

[0043] like Figures 4 to 5As shown, the inner wall of the first fixing tube 122 is provided with an abutment portion 1223, which abuts against the outer wall of the heater 13 to form a heat insulation gap 127 between the outer wall of the heater 13 and the inner wall of the first fixing tube 122. In this embodiment, the abutment portion 1223 is closely connected to the heater 13, which can fix the heater 13 in the fixing cavity 16 without shaking. At the same time, the abutment portion 1223 can also form a heat insulation gap 127 between the heater 13 and the inner wall of the fixing cavity 16. The air in the heat insulation gap 127 has a good heat insulation effect, reducing the direct heat transfer of the heater 13 to the surroundings. The heat of the heater 13 can only be transferred to the tube wall of the first fixing tube 122 through the relatively small abutment portion 1223, thus reducing heat loss.

[0044] The above are merely preferred embodiments of the present utility model and are 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.
