Aerosol generation device

Abstract

This application relates to the field of atomization equipment technology, and more particularly to an aerosol generating device, including a liquid storage component, an atomizing support, and an atomizing core. The liquid storage component has a liquid storage chamber, a suction channel penetrating the liquid storage chamber, and a liquid outlet communicating with the liquid storage chamber. The atomizing support is connected to the liquid storage component and has an atomizing chamber, an air inlet channel, an atomizing hole communicating with the atomizing chamber, and an air passage communicating with the air inlet channel. The atomizing chamber communicates with the liquid outlet, and the air passage communicates with the suction channel. The heating surface of the atomizing core covers the atomizing hole. Axially, the air inlet channel is connected to the air passage and positioned opposite the atomizing hole. Radially, the air passage is located on one side of the air inlet channel. The airflow flowing into the aerosol generating device from the air passage first flows towards the atomizing hole and collides with the atomizing core at the atomizing hole, then changes direction before flowing into the air passage. This allows the airflow to be heated by the atomizing core before flowing into the air passage, resulting in a higher and more uniform airflow temperature.

Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, and more particularly to an aerosol generating device. Background Technology

[0002] An aerosol generating device is a product that can turn a liquid aerosol generating matrix into an aerosol through heating or other means.

[0003] In related technologies, aerosol generating devices include an atomizing core structure with a heating element, which is typically attached to the surface of a liquid guiding element. In aerosol generating devices with this structure, the liquid storage chamber is located below the heating element. The atomizing liquid flows from the storage chamber downwards through the liquid guiding element to the heating element, where the aerosol generating matrix is ​​heated and atomized to form an aerosol. Under suction, the upward-flowing airflow carries the aerosol and flows sequentially through the air passage and suction channel outside the liquid guiding element, before being discharged through the suction channel. During suction, part of the airflow entering the aerosol generating device contacts the heating element, carrying the aerosol from it, while some flows directly into the air passage. This results in uneven temperature distribution of the airflow collected in the suction channel, leading to a poor suction experience in the aerosol generating device. Utility Model Content

[0024] An aerosol generating device is a product that can turn a liquid aerosol generating matrix into an aerosol through heating or other means.

[0025] In related technologies, aerosol generating devices include an atomizing core structure with a heating element, which is typically attached to the surface of a liquid guiding element. In aerosol generating devices with this structure, the liquid storage chamber is located below the heating element. The atomizing liquid flows from the storage chamber downwards through the liquid guiding element to the heating element, where the aerosol generating matrix is ​​heated and atomized to form an aerosol. Under suction, the upward-flowing airflow carries the aerosol and flows sequentially through the air passage and suction channel outside the liquid guiding element, before being discharged through the suction channel. During suction, part of the airflow entering the aerosol generating device contacts the heating element, carrying the aerosol from it, while some flows directly into the air passage. This results in uneven temperature distribution of the airflow collected in the suction channel, leading to a poor suction experience in the aerosol generating device.

[0026] In view of the above problems, this application provides an aerosol generating device to improve the suction experience of the aerosol generating device.

[0027] To illustrate the technical solution of this application, the structure of the aerosol generating device will be described below in conjunction with specific drawings and embodiments.

[0028] Figure 1 This is a schematic diagram of an aerosol generating apparatus according to an embodiment of this application. Figure 2 This is a cross-sectional view of an aerosol generating device. The aerosol generating device includes a liquid storage assembly 100, an atomizing support 200, a housing assembly 300, and an atomizing core 400 (weight not shown, but can be referenced). Figure 4 The system includes a control component 500, an atomizing bracket 200 connected to a liquid storage component 100, a housing component 300 connected to an atomizing bracket 200, and a housing component 300 and an atomizing bracket 200 forming a mounting cavity 310. The control component 500 is disposed within the mounting cavity 310 and is electrically connected to the atomizing core 400. The liquid storage component 100 has a storage chamber 110 for storing an aerosol generation matrix, and the atomizing bracket 200 has an atomizing cavity 210 that communicates with the liquid storage cavity 110, allowing the liquid storage component 100 to provide an aerosol generation matrix to the atomizing core 400. The atomizing core 400 is disposed within the atomizing cavity 210. When the control component 500 controls the atomizing core 400 to operate, the atomizing core 400 atomizes the aerosol generation matrix provided by the liquid storage component 100 to generate an aerosol. The liquid storage component 100 has a suction channel 120 that penetrates the liquid storage chamber 110, and the atomizing bracket 200 has an air inlet channel 271 and an air passage 230 that communicates with the air inlet channel 271. The air passage 230 is also connected to the suction channel 120. When the aerosol generating device is suctioned, the airflow path is: air inlet channel 271 → air passage 230 → suction channel 120, so that the aerosol generated by the atomizing core 400 flows out of the aerosol generating device with the airflow.

[0029] Figure 3 This is a schematic diagram of the liquid storage assembly 100 and the atomizing support 200 in the aerosol generating device according to an embodiment of this application. The liquid storage assembly 100 also has a liquid outlet 130 communicating with the liquid storage chamber 110, and the atomizing chamber 210 is communicating with the liquid storage chamber 110 through the liquid outlet 130. The atomizing support 200 also has an atomizing hole 220 communicating with the atomizing chamber 210, and the heating surface of the atomizing core 400 disposed in the atomizing chamber 210 covers the atomizing hole 220. In the axial direction (Y direction in the figure, which is generally upward) of the air intake channel 271, the air intake channel 271 is connected to the atomizing hole 220 through the air passage 230 and is disposed opposite to the air passage 230. In the radial direction (X direction in the figure) of the air intake channel 271, the air passage 230 is located on one side of the air intake channel 271.

[0030] Please refer to Figure 4 It is understood that the atomizing core 400 includes structures such as a liquid reservoir 410, a liquid guide 420, and a heating element 430. The heating element 430 covers the atomizing hole 220, and the liquid reservoir 410 is located on the side of the heating element 430 opposite to the atomizing hole 220. The liquid guide 420 is located between the heating element 430 and the liquid reservoir 410. The liquid reservoir 410 is used to lock the aerosol generating matrix, and the liquid guide 420 is disposed between the liquid reservoir 410 and the heating element 430. The liquid guide 420 is used to transfer the aerosol generating matrix in the liquid reservoir 410 to the heating element 430. The heating element 430 is used to heat the aerosol generating matrix so that the temperature of the aerosol generating matrix rises to the atomization temperature of the aerosol generating matrix, so that the aerosol generating matrix is ​​converted into an inhalable aerosol.

[0031] The heating surface of the atomizing core 400 covers the atomizing hole 220, that is, the heating element 430 in the atomizing core 400 covers the atomizing hole 220, so that the aerosol flows out through the atomizing hole 220 and the temperature of the air near the atomizing hole 220 rises.

[0032] In the axial direction (Y direction in the figure) of the air intake channel 271, the air intake channel 271 is connected to the air passage 230 and is opposite to the atomizing hole 220. That is, when the airflow flows into the aerosol generating device through the air intake channel 271, the airflow will blow towards the atomizing hole 220, so that the airflow contacts the heating element 430 at the atomizing hole 220, so that the aerosol and the air near the atomizing hole 220 can be mixed into the airflow flowing into the aerosol generating device from the air intake channel 271, and the heating element 430 can heat the newly flowing air into the aerosol generating device.

[0033] In the radial direction (X direction in the figure) of the air intake channel 271, the air passage 230 is located on one side of the air intake channel 271. That is, the air intake channel 271 and the air passage 230 can form a tortuous gas flow path, so that the airflow flowing into the aerosol generating device through the air intake channel 271 needs to change direction before flowing into the air passage 230. As a result, the airflow flowing into the aerosol generating device from the air intake channel 271 will first flow to the atomizing hole 220 and collide with the atomizing core 400 at the atomizing hole 220. After being heated by the heating element in the atomizing core 400, the airflow changes its flow direction and carries the aerosol to the air passage 230.

[0034] In the aerosol generating device provided in this application embodiment, since the air inlet channel 271 is connected to the atomizing hole 220 through the air passage 230 in the axial direction of the air inlet channel 271, and the air passage 230 is located on one side of the air inlet channel 271 in the radial direction of the air inlet channel 271, the airflow flowing into the aerosol generating device from the air passage 230 will first flow to the atomizing hole 220 and collide with the atomizing core 400 at the atomizing hole 220, and then change direction before flowing into the air passage 230. This allows all the airflow to be heated by the atomizing core 400 before flowing into the air passage 230, thereby making the temperature of the airflow flowing into the air passage 230 higher and more uniform, thus improving the suction experience of the aerosol generating device.

[0035] Please refer to Figure 5 and Figure 6 In some embodiments, the atomizing bracket 200 includes an atomizing base 240, an atomizing top cover 250, an air passage 260, and a first sealing member 270. The atomizing base 240 has atomizing holes 220. The atomizing top cover 250 is connected to the atomizing base 240 and surrounds the atomizing base 240 to form an atomizing cavity 210. The air passage 260 is connected to the atomizing top cover 250 and surrounds the atomizing base 240 and at least a portion of the atomizing top cover 250, forming an air passage 230. The first sealing member 270 has an air inlet channel 271, is connected to the air passage 260, and is spaced apart from the atomizing base 240.

[0036] In the above embodiments, by disassembling the atomizing bracket 200 into a structure such as a splicable atomizing base 240, an atomizing top cover 250, an air passage component 260, and a first sealing component 270, it is beneficial to assemble and maintain the atomizing bracket 200.

[0037] Please refer to Figure 6 and Figure 7 In the above embodiment, the air passage component 260 includes a main body 261 and an air passage component 262. The main body 261 is a cylindrical structure with openings at both ends. A partial atomizing cover 250 is received in the main body 261 through one of the openings, thereby connecting the atomizing cover 250 to the air passage component 260. A partial first sealing member 270 is inserted into the main body 261 through an opening opposite to the atomizing cover 250, thereby connecting the first sealing member 270 to the air passage component 260. The air passage component 262 is disposed between the main bodies 261, and the atomizing base 240 and at least a partial atomizing cover 250 together with the air passage component 262 form an air passage channel 230.

[0038] Optionally, the main body 261 and the air passage 262 are manufactured by processes such as injection molding and cutting, that is, the main body 261 and the air passage 262 are integrally formed.

[0039] In the above embodiment, the first sealing member 270 is made of elastic materials such as silicone or rubber, and the first sealing member 270 abuts against the inner wall of the main body 261 to enhance the airtightness between the first sealing member 270 and the main body 261.

[0040] In the above embodiment, the atomizing bracket 200 further includes a second sealing member 280, which has a sealing hole 281. The second sealing member 280 is housed in the main body 261 and abuts against the inner wall of the main body 261. A partial atomizing cover 250 is inserted into the sealing hole 281 and abuts against the inner wall of the sealing hole 281, thereby connecting the atomizing cover 250 with the air passage member 260 and enhancing the airtightness between the atomizing cover 250 and the air passage member 260. The second sealing member 280 is made of an elastic material such as silicone or rubber. The atomizing cover 250 abuts against the sealing hole 281 to enhance the airtightness between the atomizing cover 250 and the second sealing member 280. The second sealing member 280 abuts against the inner wall of the main body 261 to enhance the airtightness between the second sealing member 280 and the main body 261.

[0041] In other embodiments, the atomizing cover 250 directly abuts against the inner wall of the main body 261, such that the atomizing cover 250 is connected to the air passage 260, for example, the atomizing cover 250 is interference-fitted with the opening of the main body 261.

[0042] Please refer to Figure 5 In the above embodiment, the first sealing member 270 and the atomizing base 240 are spaced apart, such that the first sealing member 270, the atomizing base 240, and the air passage member 260 enclose an air intake chamber 290, which is connected to both the air intake channel 271 and the air passage 230. The air intake channel 271, the air intake chamber 290, and the air passage 230 are sequentially connected to form a tortuous gas flow path. The airflow path in the aerosol generating device is: air intake channel 271 → air intake chamber 290 → air passage 230 → suction channel 120.

[0043] Please refer to Figure 6 In some embodiments, the atomizing base 240 is provided with a first receiving groove 241, and the atomizing cover 250 is provided with a second receiving groove 251. The openings of the first receiving groove 241 and the second receiving groove 251 are arranged opposite to each other, and the first receiving groove 241 and the second receiving groove 251 enclose each other to form an atomizing cavity 210.

[0044] In the above embodiments, the atomizing base 240 and the atomizing top cover 250 can be connected by welding, threaded connection or other connection methods.

[0045] Please refer to Figure 5 and Figure 6The assembly process of the atomizer bracket 200 is as follows: First, connect the atomizer base 240 and the atomizer top cover 250; then, pass the atomizer base 240 and part of the atomizer top cover 250 through the sealing hole 281 on the second seal 280, so that the atomizer top cover 250 is connected to the second seal 280; then, insert the second seal 280 into the air passage 260, so that the second seal 280 is connected to the air passage 260. The first seal 270 is inserted into the air passage 260, so that the first seal 270 is connected to the air passage 260. The assembly of the atomizer bracket 200 is easy to operate and the assembly process is relatively simple.

[0046] In the above embodiment, the process of assembling the atomizing core 400 and the atomizing bracket 200 together is as follows: the atomizing core 400 is placed in the first receiving groove 241, then the atomizing top cover 250 is connected to the atomizing base 240, and then the atomizing top cover 250 is connected to the second sealing member 280. Next, the second sealing member 280 is connected to the air passage member 260, and the first sealing member 270 is connected to the air passage member 260.

[0047] Please refer to Figure 6 , Figure 8 and Figure 9 In some embodiments, the atomizing cover 250 is provided with a collecting groove 252 and an air passage 253, the opening of the collecting groove 252 facing opposite to the opening of the second receiving groove 251. The air passage 253 is formed on the side wall of the collecting groove 252, and the end of the air passage 230 facing away from the first seal 270 is connected to the collecting groove 252 through the air passage 253. The atomizing cover 250 is connected to the liquid storage assembly 100, and the collecting groove 252 is connected to the suction channel 120.

[0048] In the above embodiment, the air passage 230 is connected to the suction passage 120 through the air passage 253 and the collecting groove 252. That is, the flow path of the airflow in the aerosol generating device is: air inlet passage 271 → air inlet chamber 290 → air passage 230 → air passage 253 → collecting groove 252 → suction passage 120.

[0049] In the above embodiment, the bottom of the second receiving tank 251 is larger than the bottom of the collecting tank 252, and a portion of the bottom of the second receiving tank 251 overlaps with the bottom of the collecting tank 252. The atomizing cover 250 also has a liquid passage hole 255 arranged parallel to the collecting tank 252. The opening at one end of the liquid passage hole 255 penetrates the bottom surface of the second receiving tank 251, and the orientation of the liquid passage hole 255 away from the opening of the second receiving tank 251 is the same as the orientation of the opening of the collecting tank 252. When the atomizing cover 250 is connected to the liquid storage assembly 100, the collecting tank 252 communicates with the suction channel 120, and the liquid passage hole 255 communicates with the liquid outlet hole 130, allowing the aerosol generation matrix in the liquid storage chamber 110 to flow into the atomizing chamber 210 through the liquid outlet hole 130 and the liquid passage hole 255.

[0050] Please refer to Figure 5 and Figure 6 In some embodiments, the liquid storage assembly 100 includes a cup body 140, a vent tube 150, and a third sealing element 160. The cup body 140 includes a liquid storage section 141 and a suction section 142. The liquid storage section 141 is a cylindrical structure open at both ends. The suction section 142 connects to the liquid storage section 141 and covers one of the openings of the liquid storage section 141. The suction section 142 has a suction hole 142-1 communicating with the internal space of the liquid storage section 141. The vent tube 150 connects to the suction section 142 and communicates with the suction hole 142-1. The end of the vent tube 150 facing away from the suction section 142 protrudes from the liquid storage section 141. The third seal 160 is connected to the end of the liquid storage section 141 away from the suction section 142, and the air guide tube 150 is inserted into the insertion hole 161 on the third seal 160, so that the insertion hole 161, the cavity in the air guide tube 150 and the suction hole 142-1 form a suction channel 120.

[0051] In the above embodiment, the atomizing cover 250 is connected to the third seal 160, thereby connecting the atomizing cover 250 to the liquid storage assembly 100. The third seal 160 covers the collecting groove 252, and the insertion hole 161 communicates with the collecting groove 252, allowing the air passage 230 to communicate with the suction channel 120. That is, the airflow path in the aerosol generating device is: air inlet channel 271 → air inlet chamber 290 → air passage 230 → air passage 253 → collecting groove 252 → insertion hole 161 → air guide pipe 150 → suction hole 142-1.

[0054] In the above embodiment, the air passage 263 is a through groove that extends in the Y direction. One of the openings of the air passage 263 in the Y direction is covered by the second seal 280, and the other opening of the air passage 263 in the Y direction is spaced apart from the first seal 270. The air passage 263, the outer wall of the atomizing base 240, and part of the outer wall of the atomizing top cover 250 are arranged to form the air passage 263.

[0055] Please refer to Figure 7 The air passage groove 263 is constructed on the air passage part 262 in the air passage component 260.

[0056] In some embodiments, the heating surface includes a first heating region and a second heating region, which are independent of each other. The atomizing hole 220 includes a first atomizing hole 220 and a second atomizing hole 220, with the first atomizing hole 220 corresponding to the first heating region and the second atomizing hole 220 corresponding to the second heating region.

[0057] The heating surface includes a first heating area and a second heating area, meaning that the heating element 430 in the atomizing core 400 has a first heating core and a second heating core. The first heating core and the second heating core are independent of each other, meaning that the first heating core and the second heating core can alternate heating to increase the service life of the heating element 430, or the first heating core and the second heating core can also heat up simultaneously.

[0058] It should be noted that, axially, the air intake channel 271 is connected to the air passage 230, which is positioned opposite to the atomizing hole 220. Specifically, the air intake channel 271 is opposite to both the first and second atomizing holes 220. Furthermore, radially, the air passage 230 is located on one side of the air intake channel 271. Therefore, the airflow flowing into the aerosol generating device from the air passage 230 will first flow towards the first and second atomizing holes 220 and collide with the first and second heating elements, before changing direction and flowing into the air passage 230. When the first and second heating elements work alternately, all airflow can still be heated by the heating element 430 (either the first heating element, the second heating element, or both heating elements simultaneously) before flowing into the air passage 230. This results in a more uniform temperature of the airflow flowing into the air passage 230, improving the suction experience of the aerosol generating device.

[0059] In the above embodiments, the heating element 430 may be a single-core dual-electrode heating element 430 or a dual-core dual-electrode heating element 430.

[0060] Please refer to Figure 10 and Figure 11In some embodiments, the liquid storage assembly 100 includes a first partition plate 143, which divides the liquid storage chamber 110 into a first chamber 111 and a second chamber 112 that are independent of each other. The liquid outlet 130 includes a first liquid outlet 131 and a second liquid outlet 132, whereby the first liquid outlet 131 connects the first chamber 111 and the atomizing chamber 210, and the second liquid outlet 132 connects the second chamber 112 and the atomizing chamber 210.

[0061] In the above embodiment, one edge of the first partition plate 143 is connected to the outer surface of the air guide tube 150, the edge of the first partition plate 143 facing away from the air guide tube 150 is connected to the inner surface of the liquid storage section 141, and the other edge of the first partition plate 143 is connected to the surface of the suction section 142. Two first partition plates 143 are provided, and the two first partition plates 143 are arranged axially around the air guide tube 150 to divide the liquid storage chamber 110 into a first chamber 111 and a second chamber 112 that are independent of each other.

[0062] In the above embodiment, the third sealing member 160 is provided with at least two liquid outlet holes 130, which are divided into a first liquid outlet hole 131 and a second liquid outlet hole 132. The first liquid outlet hole 131 is connected to the first cavity 111, and the second liquid outlet hole 132 is connected to the second cavity 112.

[0063] In the above embodiment, the atomizing cover 250 is provided with at least two liquid passage holes 255, which are divided into a first liquid passage hole 255-1 and a second liquid passage hole 255-2. The first liquid passage hole 255-1 is connected to the first liquid outlet hole 131 in a one-to-one correspondence, and the second liquid passage hole 255-2 is connected to the second liquid outlet hole 132 in a one-to-one correspondence.

[0064] Please refer to Figure 10 and Figure 11 In some embodiments, the atomizing support 200 includes a second partition plate 256, which divides the atomizing chamber 210 into a third chamber 211 and a fourth chamber 212 that are independent of each other; the third chamber 211 is connected to the first chamber 111 through a first liquid outlet hole 131, and the fourth chamber 212 is connected to the second chamber 112 through a second liquid outlet hole 132.

[0065] In the above embodiment, the first liquid passage 255-1 is connected to the third cavity 211, and the second liquid passage 255-2 is connected to the fourth cavity 212, so that the first cavity 111 is connected to the third cavity 211 through the first liquid outlet 131 and the first liquid passage 255-1, and the second cavity 112 is connected to the fourth cavity 212 through the second liquid outlet 132 and the second liquid passage 255-2.

[0066] In the above embodiment, the first aerosol generating matrix is ​​stored in the first cavity 111, the second aerosol generating matrix is ​​stored in the second cavity 112, that is, the third cavity 211 stores a portion of the first aerosol generating matrix, and the fourth cavity 212 stores a portion of the second aerosol generating matrix.

[0067] Optionally, the components of the first aerosol generating matrix and the second aerosol generating matrix may be different. For example, the first aerosol generating matrix may be e-liquid. The second aerosol generating matrix may be at least one of e-liquid, distilled water, deionized water, electrolyte solution, or glycerol derivatives (propylene glycol, vegetable glycerol, monoglyceride, diglyceride, polyglycerol ester, acetylated glycerol ester, etc.).

[0068] When the first heating element and the second heating element heat up simultaneously, the first heating element can heat the first aerosol generating matrix in the third chamber 211, and the second heating element can heat the second aerosol generating matrix in the fourth chamber 212. The first aerosol generating matrix and the second aerosol generating matrix can be atomized at the same time to generate first aerosol and second aerosol with different flavors. This makes the flavor of the aerosol flowing into the suction channel 120 more diverse, thereby enriching the flavor of the aerosol generating device and improving the suction experience of the aerosol generating device.

[0069] When the first and second heating elements are heating independently, users can select to control the first or second heating element to work according to their taste preferences through interactive modules such as buttons, control panels, or software in electronic devices, so that the aerosol generating matrix generates the first or second aerosol, thereby improving the suction experience of the aerosol generating device.

[0070] Please refer to Figure 10 In some embodiments, the second partition plate 256 is disposed on the atomizing cover 250.

[0071] Please refer to Figure 12 In some embodiments, the atomizing core 400 further includes a support member 440, which covers the atomizing hole 220, and the heating element 430 is disposed on the side of the support member 440 away from the atomizing hole 220.

[0072] It is understandable that the heating element 430 is generally a heating mesh. The heating mesh has poor strength. In order to prevent the heating mesh from bending at the atomizing hole 220, a support 440 is set between the heating element 430 and the atomizing base 240 to support the heating element 430.

[0073] Please refer to Figure 12It is understood that the atomizing core 400 includes a support member 440, a heating element 430, a liquid guiding member 420, and a liquid storage member 410 stacked sequentially, making it easy to assemble the atomizing core 400 and the atomizing bracket 200. The process of assembling the atomizing core 400 and the atomizing bracket 200 together is as follows: the support member 440 is placed in the first receiving groove 241, and the support member 440 covers the atomizing hole 220; then the heating element 430, the liquid guiding member 420, and the liquid storage member 410 are stacked sequentially; then the atomizing top cover 250 is connected to the atomizing base 240; then the atomizing top cover 250 is connected to the second sealing member 280; then the second sealing member 280 is connected to the air passage member 260; and then the first sealing member 270 is connected to the air passage member 260.

[0074] In some embodiments, the liquid storage component 410 includes multiple layers of cotton core stacked sequentially, which can increase the liquid storage capacity of the liquid storage component 410 and extend the single use time of the aerosol generating device; it can also restrict the flow direction of the aerosol generating matrix in the liquid storage component 410 to reduce leakage of the liquid storage component 410.

[0075] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
