Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization device and an electronic atomizer. Background Technology

[0002] During the use of an e-cigarette, the aerosol flowing through the outlet tube easily condenses upon cooling. This condensate is a recycled liquid from the atomized vapor, containing extremely low levels of active ingredients, and it easily flows back onto the inner cotton padding. Re-atomizing this condensate severely compromises the atomizer's flavor profile, resulting in a diminished user experience.

[0003] To address the issue of condensate backflow, some existing technologies employ a method where the lower end of the air guide tube extends outwards to the outer cotton sheath (the outer cotton sheath is spaced outside the inner cotton sheath). The condensate is then guided back to the outer cotton sheath through the lower end of the air guide tube. However, due to factors such as changes in ambient temperature and heat generation from the atomizing components, the air pressure inside the electronic atomizer becomes unbalanced. This causes the atomizing matrix within the outer cotton sheath to be easily squeezed out by the high pressure and leak out through the air guide tube. This not only wastes the atomizing matrix but also affects the reliability and safety of the product. Utility Model Content

[0038] This application discloses an atomizing device, which includes a housing assembly, an atomizing component, an outer cotton covering, and a limiting component. The housing assembly has a mist outlet at its top, and an air outlet extending downwards from the wall of the mist outlet to form an air outlet cylinder. The inner wall of the air outlet cylinder is recessed outwards to form a return groove, the bottom end of which extends to the bottom end of the air outlet cylinder, penetrating the end wall and peripheral wall of the air outlet cylinder. The atomizing component is disposed within the housing assembly, with its top end fitted into the air outlet cylinder. The top end of the atomizing component abuts against the opening of the return groove, and is positioned between the top and bottom ends of the return groove. The atomizing component is separated from the bottom end of the return groove. A first ventilation port is formed in the portion of the top end of the atomizing component that is separated from the return groove. The first ventilation port and the return groove are offset circumferentially opposite each other in the atomizing component, and are interconnected. The outer cotton is located inside the outer shell and sleeved on the outside of the atomizing component. The first air vent is at least partially located above the outer cotton, which abuts against the bottom end of the air outlet. There is an air vent gap between the outer cotton and the outer shell component, which is opposite to and communicates with the bottom end of the return groove. A limiting component connects the outer shell component and the atomizing component, and is used to circumferentially limit the atomizing component.

[0039] In the atomizing device of this application, the condensate in the air outlet is guided to the outer cotton wrapping via the return channel. The atomizing component and the bottom of the return channel are separated by a gap to prevent the condensate from being guided to the inner cotton wrapping for re-atomization, effectively ensuring the normal taste of the atomizing device. The air exchange gap between the outer cotton wrapping and the outer shell component can achieve pressure balance between the inside of the outer shell component and the external environment, preventing high-pressure gas inside the outer shell component from squeezing the outer cotton wrapping, thereby preventing leakage of the atomizing matrix and improving the storage reliability and safety of the product. The atomizing device of this application solves the two problems of condensate backflow and atomizing matrix leakage through simple and ingenious structural improvements. It does not require complex and redundant design, and while ensuring the performance, it is also conducive to the production and assembly of the product.

[0040] Please see Figures 1 to 8 The following will mainly describe the specific structure of the atomizing device 10.

[0041] The atomizing device 10 of this application includes a housing assembly 100. The housing assembly 100 includes a housing portion 110 and a base portion 120. The bottom end of the housing portion 110 is open, and the base portion 120 covers the bottom end of the housing portion 110. The top end of the housing portion 110 has a mist outlet, and the wall of the mist outlet extends downward to form an air outlet cylinder 111.

[0042] The atomizing device 10 of this application includes an atomizing component 200, which is disposed within the outer casing 100. The top end of the atomizing component 200 is fitted into an air outlet 111. The bottom end of the air outlet 111 is gradually widened, and a connecting groove 113 is formed between the top and bottom ends of the air outlet 111, facing upward and outward. The connecting groove 113 is adapted to the shape of the atomizing component 200, and the top end of the atomizing component 200 is fitted into the connecting groove 113. The connecting groove 113 makes the connection between the atomizing component 200 and the air outlet 111 relatively stable.

[0043] The inner wall of the air outlet 111 (including the connecting groove 113) is recessed outward to form a return groove 112. The bottom end of the return groove 112 extends to the bottom end of the air outlet 111, and the bottom end of the return groove 112 penetrates the end wall and peripheral wall of the air outlet 111. The top end of the atomizing component 200 abuts against the opening of the return groove 112, and the top end of the atomizing component 200 abuts between the top and bottom ends of the return groove 112. The atomizing component 200 is separated from the bottom end of the return groove 112 (that is, the atomizing component 200 is not connected to the bottom end of the return groove 112).

[0044] A first ventilation port 211 is provided at the top of the atomizing component 200, in a portion separated from the return channel 112. The first ventilation port 211 and the return channel 112 are offset circumferentially from each other in the atomizing component 200, and are interconnected. This offset can be partial or complete. The offset arrangement of the first ventilation port 211 and the return channel 112 prevents the condensate in the return channel 112 from flowing directly down through the first ventilation port 211 to the inner cotton lining 220 of the atomizing component 200. The connection between the first ventilation port 211 and the return channel 112 allows gas to flow through both.

[0045] The atomizing device 10 of this application includes an outer cotton 300, which stores an atomizing matrix. The outer cotton 300 is disposed inside the outer casing and sleeved on the outer casing of the atomizing assembly 200. The first air exchange port 211 is at least partially located above the outer cotton 300, meaning that the first air exchange port 211 is not blocked by the outer cotton 300 or is only partially blocked by the outer cotton 300. The outer cotton 300 abuts against the bottom end of the air outlet 111, so that the condensate in the return groove 112 can flow directly to the outer cotton 300 and be actively absorbed by the outer cotton 300. There is an air exchange gap 400 between the outer cotton 300 and the outer casing assembly 100. The air exchange gap 400 is opposite to and connected to the bottom end of the return groove 112. Because the return groove 112 is connected to the first air exchange port 211, and the first air exchange port 211 is connected to the air outlet 111, the air exchange gap 400 is connected to the external environment.

[0046] In the atomizing device 10 of this application, the condensate in the air outlet 111 is guided to the outer cotton 300 through the return groove 112. The atomizing component 200 and the bottom of the return groove 112 are separated to prevent the condensate from being guided to the inner cotton 220 for re-atomization by the atomizing component 200, effectively ensuring the normal taste of the atomizing device 10. The air exchange gap 400 reserved between the outer cotton 300 and the outer shell component 100 can realize the air pressure balance between the inside of the outer shell component 100 and the external environment, and prevent the high-pressure gas inside the outer shell component 100 from squeezing the outer cotton 300, thereby preventing the leakage of the atomizing matrix and improving the storage reliability and use safety of the product. The atomizing device 10 of this application solves the two problems of condensate backflow and atomizing matrix leakage through simple and ingenious structural improvement. It does not require complex and redundant design, and while ensuring the use effect, it is conducive to the production and assembly of the product.

[0047] The atomizing device 10 of this application includes a limiting component, which connects the housing assembly 100 and the atomizing component 200. The limiting component is used to circumferentially limit the atomizing component 200. Through the circumferential limitation of the limiting component, the atomizing component 200 cannot be arbitrarily assembled, thereby ensuring that the first air exchange port 211 and the return groove 112 are in an offset position after the atomizing device 10 is assembled.

[0048] The shell portion 110 is provided with a connector 114, and the seat portion 120 is provided with a mating member 121. The connector 114 and the mating member 121 are connected to each other and prevent the shell portion 110 and the seat portion 120 from rotating circumferentially. The limiting assembly includes the connector 114 and the mating member 121. The connector 114 and the mating member 121 can be snapped together, and the connector 114 and the mating member 121 can be a snap-fit ​​protrusion and a snap-fit ​​groove (or a snap-fit ​​groove and a snap-fit ​​protrusion). The connector 114 and the mating member 121 can also be inserted, and the connector 114 and the mating member 121 can be an insert and a notch (or a notch and an insert).

[0049] The base 120 has a slot 122, and a connection position 123 is formed on one side of the inner wall of the slot 122. The bottom end of the atomizing component 200 is inserted into the slot 122. The atomizing component 200 includes pins, and the pins pass through the connection position 123. The limiting component also includes the connection position 123. The limiting connection between the atomizing component 200 and the base 120 is achieved through the limiting connection between the connection position 123 and the pins.

[0050] The number of return channels 112 can be at least two, thus providing multiple return paths for the condensate, expanding the coverage area for condensate collection and guidance, preventing local accumulation of condensate in the outlet cylinder 111, and ensuring that the condensate can flow quickly and evenly to the outer cotton 300, resulting in a better condensate return effect.

[0051] At least two return channels 112 are evenly arranged along the circumference of the air outlet 111. The number of connecting parts 114 is the same as the number of return channels 112. At least two connecting parts 114 are evenly arranged along the circumference of the shell 110. The number of mating parts 121 is the same as the number of connecting parts 114. At least two mating parts 121 are evenly arranged along the circumference of the seat 120. At least two connecting parts 114 and at least two mating parts 121 can be arbitrarily connected one-to-one. Based on the above configuration, the connection between the shell 110 and the seat 120 has a certain degree of freedom. As long as any connecting part 114 is aligned with any mating part 121, the first air exchange port 211 and the return channel 112 can be in a slightly opposite position after the atomizing device 10 is assembled, thus the assembly efficiency is relatively high.

[0052] There are four return channels 112, designated as the first channel, second channel, third channel, and fourth channel. The first channel and the second channel are arranged opposite each other. There are four first air exchange ports 211, with two ports close to the first channel and located on opposite sides of it, and the remaining two ports close to the second channel and located on opposite sides of it. This symmetrical arrangement of the return channels 112 and the first air exchange ports 211 makes the stress on the internal structure of the atomizing device 10 more uniform, reducing the impact of assembly deviations on the flow guidance and air exchange effects.

[0053] A notch 212 is provided at the top of the atomizing component 200, extending through the top of the atomizing component 200. The notch 212 can break the surface tension of the liquid and guide the condensate near the top of the atomizing component 200 in a directional manner, preventing condensate from remaining or accumulating at the edge of the top of the atomizing component 200, ensuring that this portion of condensate can flow smoothly into the third tank, further improving the overall effectiveness of condensate flow. The shape of the notch 212 can be semi-circular, semi-racetrack-shaped, semi-elliptical, or triangular, etc.

[0054] The through-hole 212 can also optimize the airflow path inside the atomizing device 10. Combined with the air exchange gap 400 and the first air exchange port 211, it can further improve the efficiency of the internal air pressure balance of the outer shell assembly 100 and indirectly reduce the risk of leakage of the atomizing matrix.

[0055] The notch 212 is opposite to the third tank. The first vent 211 is positioned away from the third tank to avoid interference with the flow of condensate in the third tank, ensuring smooth flow of condensate into the outer cotton 300 and further enhancing the anti-backflow effect. The above settings clearly delineate the condensate flow area (the third tank and the notch 212 work together) and the air pressure balance area (the first vent 211 corresponds to other return tanks 112), avoiding the problem of leakage of atomized matrix or poor condensate flow caused by the superposition of the two in the same area, and achieving efficient synergy and non-interference between the two core functions.

[0056] The atomizing component 200 includes an outer tube 210. A first air vent 211 is located at the top of the outer tube 210, and a second air vent 213 is located at the bottom of the outer tube 210. The top and bottom of the outer tube 210 are identical in structure, eliminating the need to distinguish the orientation of the top and bottom during assembly. This completely avoids incorrect or reverse assembly, reduces the difficulty of assembly personnel, significantly shortens assembly time, and improves the efficiency of mass production. The symmetrical structure of the outer tube 210 eliminates the need to distinguish between the top and bottom, reducing the types of parts, lowering the costs of mold development, production, and inventory management, while improving the versatility of parts and enhancing production flexibility. In embodiments where the top of the outer tube 210 includes a notch 212, the bottom of the outer tube 210 can also have the same notch 212 as its top.

[0057] The top of the outer cotton 300 has a horizontally connected upper gap with part of the inner top wall of the outer shell assembly 100. The outer cotton 300 has a recessed vertically connected ventilation groove 310. The bottom of the outer cotton 300 has a horizontally connected lower gap with part of the inner bottom wall of the outer shell assembly 100. The ventilation gap 400 includes the upper gap, the ventilation groove 310 and the lower gap connected in sequence. The upper gap, the ventilation groove 310 and the lower gap form a complete ventilation circuit that runs through the upper and lower parts of the outer cotton 300, realizing all-round, dead-angle-free ventilation between the inside of the outer shell assembly 100 and the external environment.

[0058] A fixing component 115 protrudes from the inner wall of the outer casing assembly 100, connecting to the outer wrapping cotton 300 and fixing the outer wrapping cotton 300. A protrusion extends downward from the top inner wall of the casing portion 110, abutting against the top end of the outer wrapping cotton 300. A boss extends upward from the top wall of the seat portion 120, abutting against the bottom end of the outer wrapping cotton 300. The fixing component 115 includes a protrusion and a boss. A raised rib extends inward from the peripheral inner wall of the casing portion 110, fitting into the ventilation groove 310, and is positioned within the ventilation groove 310 with a gap.

[0059] The portion of the atomizing component 200 that is fitted with the outer cotton 300 has multiple liquid inlets 214, which are arranged circumferentially around the atomizing component 200. At least one liquid inlet 214 has a different shape from the others, and / or the area of ​​at least one liquid inlet 214 differs from the others, and / or the height of at least one liquid inlet 214 differs from the others. This arrangement allows for adjustment of the flow rate of the atomizing matrix into the inner cotton 220 of the atomizing component 200.

[0060] This application also proposes an electronic atomizer, which includes an electronic control device and the aforementioned atomizing device 10. The atomizing device 10 is connected to the electronic control device. This application includes the aforementioned atomizing device 10 and therefore has all the beneficial effects of the aforementioned atomizing device 10. Please refer to the above for details, which will not be repeated here.
