Description

Bracket, atomizing assembly and aerosol forming device

[0001] This disclosure claims priority to the Chinese patent application filed with the Patent Office of China on July 3, 2023, with application number 202321730251.6 and application name “Stand, atomization assembly and aerosol forming device”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present application belongs to the field of aerosol generation technology, and specifically relates to a bracket, an atomization component and an aerosol forming device. Background Art

[0003] In the field of aerosol generation technology, the aerosol substrate in the liquid reservoir needs to flow through the liquid channel to the atomizer core. However, when the atomizer assembly is placed haphazardly, for example, flat on a table or put upside down in a pocket, the aerosol substrate can easily flow poorly, causing the atomizer core to dry burn and cause the core to become sticky.

[0004] Summary of the Invention

[0005] In view of this, the first aspect of the present application provides a bracket, comprising:

[0006] A main body having an atomizing cavity, and a first liquid guide channel communicating with the atomizing cavity on one side surface of the main body; and

[0007] At least one flow guide is protrudingly provided on the inner side wall of the first liquid guiding channel, and the flow guide is used to guide the aerosol substrate in the first liquid guiding channel to flow into the atomization chamber.

[0008] The first aspect of the present application provides a support body with a protruding flow guide, which is located on the inner sidewall of the first liquid-conducting channel. The flow guide guides the flow of the aerosol substrate, increasing its flow rate within the first liquid-conducting channel and allowing it to quickly reach the atomizer core, thereby reducing the risk of dry-burning and resulting in burns. Furthermore, the flow guide guides gas flow.

[0009] On the other hand, because the first liquid-conducting channel of the bracket is relatively narrow, if the atomizer assembly is placed haphazardly, the aerosol substrate in the first liquid-conducting channel can easily react with the gas to form bubbles, which can easily clog the first liquid-conducting channel. The flow guide can also burst and cut the bubbles in the first liquid-conducting channel, allowing them to float upward along the flow guide, further reducing the chance of the atomizer core burning dry and causing it to become sticky.

[0048] This embodiment provides a holder 1 comprising a body 11 and at least one flow guide 12. The body 11 defines an atomization chamber 1b, and a first liquid-conducting channel 1a is formed on one side of the body 11, communicating with the atomization chamber 1b. Furthermore, at least one flow guide 12 is protruding from the inner sidewall of the first liquid-conducting channel 1a, and is configured to guide aerosol substrate within the first liquid-conducting channel 1a to flow into the atomization chamber 1b.

[0049] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish different objects rather than to describe a specific order.

[0050] The bracket 1 provided in this embodiment can be applied to the atomizer assembly 2. Among them, the atomizer assembly 2 provided in this embodiment mainly includes the bracket 1 and the bracket seal 21, but this does not mean that the atomizer assembly 2 can only include these two structures. As shown in Figures 1 to 4, the atomizer assembly 2 may include a shell 22, an air guide tube 23, an atomizer core 24, a base 25, a sealing structure 26, an electrode 27, etc. The transmission direction of the gas and aerosol in the atomizer assembly 2 is shown in the direction D1 in Figure 2. The transmission direction of the aerosol substrate in the atomizer assembly 2 is shown in the direction D2 in Figure 4. Next, the structures of the atomizer assembly 2 will be introduced in detail one by one.

[0051] The atomization assembly 2 includes a shell 22, and the shell 22 includes a first end 2113 and a second end 2114 that are arranged opposite to each other. The first end 2113 has a first opening, and the second end 2114 has a second opening. Optionally, the second end 2114 can be a suction nozzle or an air outlet. Optionally, the suction nozzle is installed at the second end 2114, or the suction nozzle is connected to the second opening. Optionally, the shell 22 includes a liquid storage chamber 221 for storing an aerosol substrate. Optionally, the air duct 23 is arranged in the shell 22 and is connected to the second opening. Optionally, the shell 22 and the air duct 23 are interconnected as a whole, and the shell 22 and the air duct 23 are an integrated structure.

[0052] The atomizer assembly 2 further includes a bracket 1, which is disposed within the housing 22 and adjacent to the first opening. The bracket 1 has a first liquid-conducting channel 1a and an exhaust port. Optionally, the first liquid-conducting channel 1a of the bracket 1 communicates with the liquid storage chamber 221, and the exhaust port of the bracket 1 communicates with the air duct 23. Optionally, the bracket 1 and the housing 22 enclose an atomizing chamber 1b.

[0053] The atomizer assembly 2 further includes an air guide tube 23 having an air channel, one end of which is connected to the exhaust port, and the other end of which is connected to the second opening. Optionally, the housing 22, the bracket 1, and the air guide tube 23 collectively form a liquid storage chamber 221 for storing the aerosol substrate.

[0054] The atomizer assembly 2 also includes an atomizer core 24, which is installed in the bracket 1. The atomizer core 24, the bracket 1, and the base 25 are arranged to form an atomizer chamber 1b, and the atomizer chamber 1b is connected to the exhaust port. The atomizer core 24 includes a base and a heating element. The base has a liquid absorption surface and an atomizing surface. The heating element is arranged on the atomizing surface. The liquid absorption surface is exposed through the first liquid guide channel 1a, so that the aerosol substrate in the liquid storage chamber 221 can be transferred to the liquid absorption surface through the first liquid guide channel 1a, and the aerosol substrate on the liquid absorption surface is transferred to the atomizing surface, so that the heating element heats and atomizes the aerosol substrate to form an aerosol located in the atomizer chamber 1b. The aerosol can be discharged through the atomizer chamber 1b, the exhaust port, the air guide channel, and the second opening in sequence, or be inhaled by the user. Optionally, the base includes but is not limited to absorbent cotton, porous ceramics, porous metals, porous glass or other porous structures that can absorb aerosol substrates.

[0055] The atomizer assembly 2 further includes a base 25, which is mounted on the first end 2113 of the housing 22 and seals the first opening. The base 25 supports the bracket 1. The atomizer assembly 2 further includes an electrode 27, which is mounted on the base 25 and passes through the base 25 to be electrically connected to the heating element.

[0056] In addition, the atomizing assembly 2 also has an air inlet connected to the atomizing chamber 1b. For example, the air inlet can be provided on the base 25, the housing 22, etc.

[0057] Of course, in addition to the above components, various sealing structures 26 may also be included, such as a bracket seal 21 for sealing the bracket 1 and the shell 22, an atomizer core 24 seal for sealing the atomizer core 24 and the bracket 1, a base 25 seal for sealing the base 25 and the shell 22, baffle silicone, etc.

[0058] In the atomizer assembly 2, the aerosol substrate within the liquid storage chamber 221 can be transferred to the liquid absorption surface of the base body through the first liquid guide channel 1a of the bracket 1, and then transferred to the atomization surface through the liquid absorption surface. The heating element provided on the atomization surface can heat the aerosol substrate and atomize it into an aerosol. The aerosol is stored in the atomization chamber 1b. External gas can enter the atomization chamber 1b through the air inlet and mix with the aerosol. The mixed gas is discharged through the atomization chamber 1b, the exhaust port of the bracket 1, the air guide channel of the air guide tube 23, and the second opening of the housing 22 (the air outlet of the mouthpiece), or is inhaled by the user.

[0059] The main body 11 of the bracket 1 provided in this embodiment is provided with a guide member 12, and the guide member 12 is provided on the inner side wall of the first liquid guiding channel 1a. The first liquid guiding channel 1a is composed of the liquid guiding hole of the main body 11. One side of the first liquid guiding channel 1a is connected to the liquid storage chamber 221, and the other side is connected to the atomization chamber 1b. The aerosol substrate in the liquid storage chamber 221 can flow to the atomization core 24 in the atomization chamber 1b through the first liquid guiding channel 1a. The guide member 12 can also be understood as a guide column. Optionally, the liquid guiding hole is arranged along the axial direction of the main body 11, passing through the upper surface and the lower surface of the main body 11. Optionally, the guide member 12 is arranged along the axial direction of the main body 11. Optionally, the upper surface of the guide member 12 is flush with the upper surface of the main body 11; the lower surface of the guide member 12 is flush with the lower surface of the main body 11.

[0060] Optionally, the width of the flow guide 12 is 0.4 mm to 0.8 mm, and the height of the flow guide 12 protruding from the inner side wall of the first liquid guiding channel 1 a is 0.4 mm to 0.8 mm.

[0061] On the one hand, the flow guide 12 can guide the flow of the aerosol substrate, increase the flow rate of the aerosol substrate in the first liquid guide channel 1a, and quickly flow the aerosol substrate to the atomizer core 24, thereby reducing the chance of the atomizer core 24 burning dry and causing the core to become sticky. In addition, the flow guide 12 can also guide the flow of gas.

[0062] On the other hand, because the first liquid-conducting channel 1a of the bracket 1 is relatively narrow, when the atomizer assembly 2 is placed haphazardly, the aerosol substrate in the first liquid-conducting channel 1a easily reacts with the gas to form bubbles, which can easily clog the first liquid-conducting channel 1a. The flow guide 12 can also rupture and break the bubbles in the first liquid-conducting channel 1a, causing them to float upward along the flow guide 12, thereby further reducing the chance of the atomizer core 24 burning dry and causing the core to become sticky.

[0063] Given the structural limitations, the liquid channel between the liquid storage chamber 221 and the atomizer core 24 is relatively narrow. When the atomizer assembly 2 is placed flat on a table or placed upside down in a pocket, the channel is essentially filled with gas. In this situation, if the user directly inhales the atomizer without the aid of the flow guide 12, the bubbles in the channel are large and the channel is small. There is a high probability that the bubbles will get stuck in the channel, preventing the aerosol substrate from entering the atomizer core 24, resulting in poor oil flow and burnt core.

[0064] Therefore, in this embodiment, the guide member 12 is protruded from the first liquid guiding channel 1a of the bracket 1 to allow the aerosol substrate to flow smoothly in the first liquid guiding channel 1a, thereby reducing the probability of the atomizer core 24 being dry-burned and causing the core to become sticky.

[0065] In the related art, the space required for the liquid-conducting channel is relatively large, in other words, the space required for the oil inlet path is relatively large. In addition, when the atomizer assembly 2 is placed flat or upside down and then picked up for inhalation, the aerosol substrate in the liquid storage chamber 221 is connected to the atomizer core 24 relatively slowly.

[0066] This embodiment utilizes a protruding flow guide 12 within the first liquid-conducting channel 1a of the bracket 1 to facilitate smooth flow of the aerosol substrate within the first liquid-conducting channel 1a. Any remaining aerosol substrate is also quickly directed back into the first liquid-conducting channel 1a, preventing the aerosol-generating device from being left flat on a table or held upside down in a pocket, which can lead to condensation. Furthermore, this design requires less space for the liquid-conducting channel, making it more effective when the channel is confined, thereby optimizing structural space utilization.

[0067] Please refer to Figures 1 to 8. In one embodiment, at least one guide groove 13 is recessed on the inner side wall of the first liquid guiding channel 1a. The guide groove 13 is used to guide the aerosol substrate in the first liquid guiding channel 1a to flow to the atomization chamber 1b.

[0068] The guide groove 13 is spaced apart from the guide member 12 and disposed on the inner sidewall of the first liquid guiding channel 1a. Optionally, the guide groove 13 is disposed axially along the body 11. Optionally, the guide groove 13 extends through the upper and lower surfaces of the body 11. Optionally, the guide groove 13 has a width of 0.4 mm to 0.8 mm and a depth of 0.4 mm to 0.8 mm.

[0069] In this embodiment, a concave guide groove 13 is formed on the inner wall of the first liquid-conducting channel 1a. The guide groove 13 guides the flow of the aerosol substrate, increasing its flow rate within the first liquid-conducting channel 1a and allowing it to quickly reach the atomizer core 24, thereby reducing the chance of the atomizer core 24 burning dry and causing burns. Furthermore, the guide groove 13 also guides gas flow.

[0070] Please refer to Figures 1 to 9, Figure 9 is a partial enlarged view of Figure 7. In one embodiment, the bracket 1 satisfies at least one of the following conditions: the guide groove 13 includes a first side wall and a second side wall arranged opposite to each other, and an end of the first side wall away from the inner side wall of the first liquid guiding channel 1a is connected to an end of the second side wall away from the inner side wall of the first liquid guiding channel 1a to form a sharp angle; and / or, the guide member 12 includes a third side wall and a fourth side wall arranged opposite to each other, and an end of the third side wall away from the inner side wall of the first liquid guiding channel 1a is connected to an end of the fourth side wall away from the inner side wall of the first liquid guiding channel 1a to form a sharp angle.

[0071] The shapes of the guide groove 13 and the guide member 12 can be triangle, quadrilateral, polygon, trapezoid, etc., which are not limited in this embodiment.

[0072] The guide groove 13 is concave and pointed, and the angle between the first side wall and the second side wall forms a narrow gap, which is conducive to increasing the downward capillary force, making it easier to guide the flow of the aerosol substrate, making it easier for the aerosol substrate to flow to the atomizer core 24, and further reducing the probability of the atomizer core 24 being dry-burned and causing the core to become sticky.

[0073] The guide member 12 is convex and pointed, so that the guide member 12 can more easily cut bubbles. After large bubbles are divided into small bubbles, they are more likely to float up, thereby further reducing the probability of the atomizer core 24 burning dry and causing the core to become sticky.

[0074] Referring to Figures 1-9 , in one embodiment, the inner sidewalls of the first liquid-conducting channel 1a include two opposing first inner sidewalls and two opposing second inner sidewalls, each of which is bent and connected to the second inner sidewall. The bracket 1 satisfies at least one of the following conditions: there are at least two guide grooves 13, each of which is located on the first inner sidewall. And / or, there are at least two guide members 12, each of which is located on the second inner sidewall.

[0075] Optionally, the two guide grooves 13 are arranged along the width direction of the body 11, and the two guide members 12 are arranged along the length direction of the body 11. Optionally, the shape of the first liquid guiding channel 1a is quadrilateral, polygonal, irregular, etc., which is not limited in this embodiment.

[0076] In this embodiment, the two guide grooves 13 are respectively provided on two opposite first inner side walls; and / or, the two guide members 12 are respectively provided on two opposite second inner side walls, so that the guide grooves 13 and the guide members 12 are evenly distributed on the inner side wall of the first liquid guiding channel 1a, thereby improving the guiding effect of the aerosol substrate in the first liquid guiding channel 1a, and further reducing the probability of the atomizer core 24 being dry-burned and causing the core to become sticky.

[0077] Please refer to Figures 1 to 8. In one embodiment, along the direction from the first liquid guiding channel 1a to the atomization chamber 1b, the first liquid guiding channel 1a includes a first sub-inner sidewall 141 and a second sub-inner sidewall 142. The first sub-inner sidewall 141 is farther away from the atomization chamber 1b than the second sub-inner sidewall 142. The first sub-inner sidewall 141 is inclined toward the direction close to the atomization chamber 1b and is bent to connect to the second sub-inner sidewall 142.

[0078] The first liquid-conducting channel 1a connects the liquid storage chamber 221 with the atomizing chamber 1b. The aerosol substrate in the liquid storage chamber 221 can flow sequentially through the first liquid-conducting channel 1a and the atomizing chamber 1b, thereby flowing onto the atomizing core 24. The inner diameter of the first sub-inner sidewall 141 away from the atomizing chamber 1b is larger than the inner diameter of the first sub-inner sidewall 141 closer to the atomizing chamber 1b. In other words, the inner diameter of the first sub-inner sidewall 141 gradually decreases along the direction from the first liquid-conducting channel 1a to the atomizing chamber 1b.

[0079] Optionally, the angle between the extension direction of the first sub-inner sidewall 141 and the axial direction of the bracket 1 is 10°-40°. In other words, the angle between the extension direction of the first sub-inner sidewall 141 and the horizontal direction is 100°-130°.

[0080] In this embodiment, by providing an inclined first sub-inner sidewall 141 in the first liquid-conducting channel 1a, the flow rate of the aerosol substrate on the first sub-inner sidewall 141 can be increased, so that the aerosol substrate flows quickly to the atomizer core 24, thereby reducing the probability of the atomizer core 24 being burnt dry and causing the core to become sticky.

[0081] Please refer to Figures 1-12. Figure 10 is a side view of a stent seal provided in one embodiment of the present application. Figure 11 is a top view of a stent seal provided in one embodiment of the present application. Figure 12 is a cross-sectional view of the stent seal along the BB direction in Figure 3 of the present application.

[0082] The present application also provides an atomizer assembly 2, which includes a bracket seal 21 and the bracket 1 provided above in the present application. The bracket seal 21 is installed on the surface of the main body 11 where the first liquid guide channel 1a is set. The bracket seal 21 has a second liquid guide channel 21a connected to the first liquid guide channel 1a.

[0083] The atomizer assembly 2 provided in this embodiment adopts the bracket 1 provided in the above application, and a flow guide member 12 is protruded from the first liquid guide channel 1a of the bracket 1, so that the aerosol substrate flows smoothly in the first liquid guide channel 1a, thereby reducing the probability of the atomizer core 24 being dry-burned and causing the core to become sticky.

[0084] Please refer to Figures 1 to 12. In one embodiment, along the direction from the second liquid guiding channel 21a to the first liquid guiding channel 1a, the second liquid guiding channel 21a includes a third sub-inner side wall 2121 and a fourth sub-inner side wall 2122. The third sub-inner side wall 2121 is farther away from the bracket 1 than the fourth sub-inner side wall 2122. The third sub-inner side wall 2121 is inclined toward the direction close to the first liquid guiding channel 1a and is bent to connect to the fourth sub-inner side wall 2122.

[0085] The second liquid-conducting channel 21a connects the liquid storage chamber 221 with the first liquid-conducting channel 1a. The aerosol substrate in the liquid storage chamber 221 can flow sequentially through the second liquid-conducting channel 21a, the first liquid-conducting channel 1a, and the atomizing chamber 1b, ultimately reaching the atomizing core 24. The inner diameter of the third sub-inner sidewall 2121 farther from the bracket 1 is greater than the inner diameter of the third sub-inner sidewall 2121 closer to the bracket 1. In other words, the inner diameter of the third sub-inner sidewall 2121 gradually decreases along the direction from the second liquid-conducting channel 21a to the first liquid-conducting channel 1a.

[0086] Optionally, the angle between the extension direction of the third sub-inner sidewall 2121 and the axial direction of the bracket seal 21 is 20°-50°. In other words, the angle between the extension direction of the third sub-inner sidewall 2121 and the horizontal direction is 110°-140°. Optionally, the groove wall of the drainage groove 211 is connected to the third sub-inner sidewall 2121, and the angle between the extension direction of the groove bottom wall of the drainage groove 211 and the extension direction of the third sub-inner sidewall 2121 is 10°-22°.

[0087] In this embodiment, by providing an inclined third sub-inner sidewall 2121 in the second liquid-conducting channel 21a, the flow rate of the aerosol substrate on the third sub-inner sidewall 2121 can be increased, so that the aerosol substrate flows quickly to the atomizer core 24, thereby reducing the probability of the atomizer core 24 being burnt dry and causing the core to become sticky.

[0088] Please refer to Figures 1 to 12. In one embodiment, the surface of the bracket seal 21 facing away from the bracket 1 is provided with at least one drainage groove 211 connected to the second liquid guiding channel 21a. The groove wall of the drainage groove 211 is connected to the inner wall of the second liquid guiding channel 21a. The drainage groove 211 is used to guide the aerosol substrate located on the surface of the bracket seal 21 facing away from the bracket 1 to flow to the second liquid guiding channel 21a.

[0089] Optionally, the width of the drainage groove 211 is 0.4-1.5 mm. The depth of the drainage groove 211 is 0.4-1.5 mm. Optionally, the groove wall of the drainage groove 211 is connected to the third sub-inner sidewall 2121.

[0090] In this embodiment, a drainage groove 211 is recessed into the inner wall of the second liquid-conducting channel 21a. This groove guides the flow of the aerosol substrate, increasing its flow rate within the second liquid-conducting channel 21a and allowing it to quickly reach the atomizer core 24. This reduces the chance of the atomizer core 24 burning dry and causing burns. Furthermore, the drainage groove 211 also guides gas flow.

[0091] Please refer to Figures 1 to 12. In one embodiment, the inner side wall of the second liquid guiding channel 21a includes two third inner side walls arranged opposite to each other, and two fourth inner side walls arranged opposite to each other, each of the third inner side walls is bent and connected to the fourth inner side wall, and the groove wall of the drainage groove 211 is connected to the bent connection between the third inner side wall and the fourth inner side wall.

This can also be understood as positioning the drainage groove 211 at the bend of the inner sidewall of the second liquid-conducting channel 21a. In related art, aerosol substrate is prone to remaining at the bend of the support seal 21. Therefore, positioning the drainage groove 211 at the bend between the third and fourth inner sidewalls facilitates directing any remaining aerosol substrate to the second liquid-conducting channel 21a, allowing it to quickly flow to the atomizer core 24, thereby reducing the risk of the atomizer core 24 burning dry and causing burns.

[0096] The first sub-groove wall 2111 and the second sub-groove wall 2112 are both inclined away from the bracket 1, and the first sub-groove wall 2111 is connected to the second sub-groove wall 2112. In this embodiment, a conical drainage groove 211 is provided between the two second liquid-conducting channels 21a to facilitate diversion of the aerosol substrate remaining on the surface of the bracket seal 21 between the two second liquid-conducting channels 21a to the second liquid-conducting channels 21a, allowing the aerosol substrate to flow quickly to the atomizer core 24, thereby reducing the chance of the atomizer core 24 burning dry and causing burns.

[0097] Referring to Figures 1-12 , in one embodiment, the support seal 21 satisfies at least one of the following conditions: the drainage groove 211 includes a fifth sidewall and a sixth sidewall disposed opposite each other, with the end of the fifth sidewall distal from the inner sidewall of the second liquid-conducting channel 21a connected to the end of the sixth sidewall distal from the inner sidewall of the second liquid-conducting channel 21a, forming a sharp angle. Furthermore, / or, the drainage groove 211 includes a bottom wall and sidewalls connected to the bottom wall, with the bottom wall and sidewalls forming a sharp angle.
