[0002] An electronic atomization device generally includes an atomization device and a power supply device electrically connected to the atomization device. The atomization component of the atomization device can heat and atomize an aerosol-forming matrix stored in the atomization device under the electrical drive of the power supply device. After the aerosol-forming matrix is ​​atomized into an aerosol, it can be inhaled and consumed by the user.

[0003] After a certain number of puffs, the electronic atomization device will produce some aerosol condensate in the suction nozzle. After a certain number of uses, the condensate will be inhaled into the mouth, making the consumer's taste experience uncomfortable.

[0004] The prior art usually provides a blocking plate or a reflux chamber at the nozzle opening to prevent condensate from being sucked into the nozzle. This type of design is not only complex in structure, but also exacerbates the generation of condensate due to the long residence time of the aerosol in the device. It also causes the aerosol output at the outlet to have poor flow and uneven concentration, affecting the user's experience of inhaling the aerosol. Utility Model Content

[0009] The raised portion is arranged in the cavity, the raised portion is provided with a first hole along the direction of the aerosol channel, the first hole is connected to the aerosol channel, and the outer wall of the raised portion and the inner wall of the cavity jointly define a cavity that can accommodate aerosol condensate.

[0010] Furthermore, the raised portion further includes a second hole arranged along the direction of the aerosol channel, and the second hole is communicated with the aerosol channel.

[0011] Furthermore, the diameter of the first hole is larger than the diameter of the second hole.

[0012] Furthermore, the ratio m of the aperture of the first hole to the aperture of the second hole satisfies: 1 <m<5。

[0013] Furthermore, there are multiple second holes.

[0014] Furthermore, the number a of the second holes satisfies: 1 <a<15。

[0015] Furthermore, the outer wall of the raised portion is inclined.

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments to be described below are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0045] It should also be understood that the terms used in this utility model embodiment specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model embodiments. As used in the utility model embodiment specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0046] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0047] The utility model provides a condensation storage component and an electronic atomization device, which are used to solve the technical problems of the existing electronic atomization device that the aerosol stays in the electronic atomization device for too long due to the anti-condensation device, which increases the generation of condensate and also causes the aerosol to flow poorly and the concentration to be uneven, thus affecting the experience of inhaling the aerosol. By optimizing the existing anti-condensation device, the structure of the anti-condensation device is simplified. The optimized condensation storage device has the characteristics of simple structure, small size, detachable installation, and low manufacturing cost, and is more suitable for mass production. At the same time, it reduces the generation of condensed aerosol and ensures smooth flow and uniform concentration of aerosol during inhalation, thereby achieving the technical effect of maintaining sufficient aerosol concentration and a good supply speed and improving the experience of inhaling aerosol.

[0048] See also Figure 1 and Figure 2 As shown, the aerosol generating device 10 provided in the embodiment of the utility model is used to heat the aerosol generating substrate 211 stored in the aerosol substrate storage chamber 21 to generate aerosol for the user to use.

[0049] like Figure 1 and Figure 2As shown, in some embodiments, the atomizing device 10 includes a storage assembly 23, an atomizer 20, a power assembly, a nozzle 11, and an air flow channel 31. The power assembly is disposed at the bottom of the atomizer 20 and is electrically connected to the atomizer 20. An air flow channel 31 is disposed in the nozzle 11 at one end of the atomizing device body, the storage assembly 23 and the atomizer 20 are replaceably disposed in the atomizing device body, the nozzle 11 is detachably mounted on the device body and sleeved on the outside of the atomizer 20, and the atomizer 20 can be connected to the external atmosphere through the nozzle 60. An aerosol generating matrix 211 is stored in the atomizer 20, and the power assembly is used to provide electrical energy to the atomizer 20 and convert it into thermal energy for heating, thereby heating the aerosol generating matrix 211 in the atomizer 20 to generate an aerosol for the user to take.

[0050] When the aerosol generating matrix 211 in the atomizer 20 is used up, the atomizer 20 can be pulled out from the power supply assembly as a whole and separated from the nozzle 11 and the storage assembly 23 to be replaced with a new atomizer 20 without the need to manually add the aerosol generating matrix 211 in the atomizer 20, thereby ensuring the amount of the aerosol generating matrix 211 and the concentration of the aerosol generated, and avoiding the introduction of other impurities in the process of manually adding the aerosol generating matrix 211.

[0051] like Figure 1-Figure 3 As shown, in some embodiments, the atomizer 20 includes an aerosol matrix storage chamber 21, a central tube 22, an oil-conducting cotton 24, and a ceramic atomizing core 25. There are two aerosol matrix storage chambers 21, which are respectively arranged on both sides of the atomizing element 20. The central tube 22, the oil-conducting cotton 24, and the ceramic atomizing core 25 are combined from the outside to the inside to form an assembly, and the side wall of the central tube 22 is provided with a hole for the aerosol generating matrix 211 to penetrate into the assembly. The aerosol generating matrix 211 enters the interior of the assembly through the hole, and after soaking the oil-conducting cotton 24, it contacts the inner wall or the heating wire inside the ceramic atomizing core 25 through the pores formed by sintering in the ceramic atomizing core 25. After the entire device is started, the power supply component starts to supply power, and the heating wire is energized to generate a large amount of heat, thereby heating the aerosol generating matrix 211 to generate aerosol and reach the suction nozzle 11 along the aerosol channel 31 to enter the outside world.

[0052] like Figure 4 , Figure 5 and Figure 7 As shown, further, the solidification storage assembly 23 includes a cavity 231 , a protrusion 232 , a hole 233 and a cavity 234 .

[0053] The condensation storage component 23 forms a cavity 231; the protrusion 232 is arranged in the cavity 231; the protrusion 232 is provided with a first hole 2331 along the direction of the aerosol channel 31, the first hole 2331 is connected to the aerosol channel 31, and the outer wall of the protrusion 232 and the inner wall of the cavity 231 jointly define a cavity 234 that can accommodate aerosol condensate.

[0054] In this way, the aerosol channel 31 passes through the first hole 2331, and the air in the external environment can flow into the ceramic atomization core 25 through the airway of the device body. The aerosol generated by the atomization of the aerosol generating matrix 211 in the ceramic atomization core 25 enters the outside through the first hole 2331 and the nozzle.

[0055] In some of the embodiments, the storage component 23 is made of a material with high stability, good flexibility, moderate strength, and strong heat resistance and cold resistance, including but not limited to silicone, thermoplastic polyurethane elastomer rubber (Thermoplastic polyurethanes, TPU), polyurethane (polyurethane, PU), and fluororubber (Fluororubber, PFM).

[0056] like Figure 3 As shown, in some of the embodiments, the condensation storage component 23 is disposed in the device body to limit the flow of aerosol in the aerosol channel 31, and the path of the aerosol channel 31 is determined by the structure of the nozzle. In some of the embodiments, the airflow channel of the entire device is a single path defined by the internal structure of the device body, the central tube 22 and the nozzle 11, and the airflow remains unobstructed in the path.

[0057] The shape of the storage assembly 23 is suitable for limiting the aerosol passage 31, and its cross-sectional area can cover the maximum cross-sectional area of ​​the structural cavity that forms the limiting aerosol passage 31, such as Figure 3 As shown, in some of the embodiments, the condensation storage component 23 is a cylindrical structure with one end open, and the cross-sectional area of ​​the circle can cover the entire cross-sectional area of ​​the cavity of the central tube 22 to ensure that as much aerosol as possible passes through the condensation storage component 23 to maintain the aerosol concentration in the aerosol channel 31.

[0058] like Figure 3 As shown, in some embodiments, the condensate storage component 23 is disposed on the top of the central tube 22 , specifically, between the connecting portion of the central tube 22 and the nozzle 11 , so as to be disposed at the entrance of the aerosol channel 31 in the nozzle 11 .

[0059] like Figure 4-Figure 7 As shown, in some of the embodiments, the protrusion direction of the protrusion 232 is the same as the airflow direction to avoid obstruction to the flow of aerosol in the aerosol channel 31 .

[0060] As Figure 3-Figure 5 and Figure 7 shown, in some embodiments, the outer wall of the protrusion 232 and the inner wall of the cavity 231 jointly define a cavity 234. After the electronic atomization device is used multiple times, the aerosol in the aerosol passage 31 in the mouthpiece 11 will condense to generate some condensate. These condensates will aggregate into large-particle condensed aerosol, and due to the action of gravity and inertia, they will flow downward along the inner wall of the mouthpiece 11 and enter the cavity 234 for storage, reducing the reflux of large-particle smoke to the aerosol matrix storage cavity 21.

[0061] As Figure 4-Figure 8 shown, in some embodiments, the protrusion 232 further includes a second hole 2332 arranged along the direction of the aerosol passage 31. The second hole 2332 is communicated with the aerosol passage 31 to improve the passing efficiency of the aerosol in the aerosol passage 31.

[0062] As Figure 4-Figure 7 shown, in some embodiments, the aperture diameter of the first hole 2331 is different from that of the second hole 2332, and the aperture diameter of the second hole 2332 is smaller. The second hole 2332 has a screening effect, which can allow small-particle aerosol to pass through and enter the mouthpiece, and at the same time has a certain resistance to block the inflow of large-particle condensed aerosol into the mouthpiece. During the flow of the aerosol generated by the heating wire on the ceramic atomization core 25 along the aerosol passage 31, the aerosol is prone to aggregation to form larger aerosol groups. When these groups rise to a distance from the heating area, the vapor molecules on the periphery of the larger aerosol groups are more likely to change phase and condense on the inner wall surface of the mouthpiece to form aerosol condensate beads. Through the screening of the second hole 2332, the large-particle aerosol groups aggregated near the aperture diameter are reduced in scale under the action of the heat transfer of the heating wire and the molecules between the groups to pass through the hole. The aperture diameter of the first hole 2331 is larger, which can allow larger-particle aerosol to pass through, improve the passing efficiency of the aerosol, maintain the stability of the aerosol concentration, and improve the user experience of consuming the aerosol.

[0063] As Figure 6 、 Figure 7 shown, in some embodiments, the ratio m of the aperture diameter of the first hole 2331 to that of the second hole 2332 satisfies: 1 < m < 5. When the ratio of the aperture diameters of the two is equal to or less than 1, the aperture diameter of the first hole 2331 is small, which is not sufficient to maintain the passing rate of the aerosol, and the aerosol will cause congestion inside the ceramic atomization core 25, and it is easy to cause obvious changes in the aerosol concentration during continuous suction, resulting in a poor experience; when the ratio of the aperture diameters of the two is greater than 5, the aperture diameter of the first hole 2331 is too large and the aperture diameter of the second hole 2332 is too small, and the second hole 2332 does not have a screening effect, and the aerosol condensate generated by the larger-particle aerosol groups increases, resulting in waste.

[0064] As Figure 4-Figure 7 As shown, in some embodiments, there are multiple numbers of the second holes 2332. By increasing the number of small holes, the filtration area of the condensate storage component 23 can be increased. At the same time, due to the screening effect of the second holes 2332, increasing the number of the second holes 2332 can improve the screening efficiency and increase the number of smaller particle aerosol groups.

[0065] Such as Figure 4-Figure 7 As shown, in some embodiments, the number a of the second holes 2332 satisfies: 1 < a < 15. When the number of the second holes is small, in order to maintain the filtration area of the condensate storage component 23 and the number of aerosols in the aerosol passage 31, it is necessary to increase the aperture or the number of the first holes 2331, and the probability of larger aerosol groups passing through increases; if the number of the second holes 2332 is too large, the aperture or the number of the first holes 2331 will become smaller, and the number and aperture of the first holes 2331 and the second holes 2332 will tend to be the same. The number of aerosols allowed to pass through the condensate storage component 23 is relatively large, and the corresponding number of aerosol condensate liquids generated is also relatively large.

[0066] Such as Figure 4 、 5 As shown, in some embodiments, the outer wall of the convex portion 232 is inclined, specifically, the included angle between the outer wall of the convex portion 232 and the inner wall of the cavity 231 is an obtuse angle. When the condensate liquid flows downward under the action of gravity and inertia, part of the condensate liquid will adsorb and accumulate on the outer wall of the convex portion 232, and the outer wall of the convex portion 232 with an inclined setting and an obtuse included angle with the inner wall of the cavity 231 is more conducive to the agglomerated liquid droplets flowing along the outer wall of the convex portion 232 into the cavity 234.

[0067] Such as Figure 2 、 Figure 3 、 Figure 7 As shown, in some embodiments, the vertical height H of the condensate storage component 23 satisfies: 2.8 mm < H < 4.8 mm. When the height of the condensate storage component 23 is less than 2.8 mm, the component is not easy to assemble. At the same time, the aperture is too small, and the flow of the aerosol is too slow, resulting in a poor experience of sucking. When the height of the condensate storage component 23 is greater than 4.8 mm, a larger volume is required, the volume of the entire electronic atomization device is large and inconvenient to use, and the distance of the small holes that the aerosol needs to pass through becomes larger, and the concentration of the aerosol is unstable, thereby affecting the taste.

[0068] Such as Figure 3-Figure 4 As shown, in some embodiments, the cavity 231 and the convex portion 232 are integrally formed, which is convenient and fast for manufacturing, and the product structure and performance of the obtained condensate storage component 23 are stable. At the same time, it is also convenient for the subsequent manufacturing of the first holes 2331 and the second holes 2332.

[0069] Such as Figure 2 、 Figure 3As shown, in some of the embodiments, the solidification storage assembly 23 is detachably connected to the device body.

[0070] Furthermore, based on the fact that the condensation storage component 23 is made of a material with high stability, good flexibility, moderate strength, and strong heat resistance and cold resistance, it can act as a seal between the central tube 22 and the nozzle 11. The aerosol generated by the central tube 22 enters the nozzle through the condensation storage component 23 to ensure a sealing effect.

[0071] This embodiment also provides an atomization device, comprising

[0072] Device body;

[0073] A suction nozzle 11 is provided at one end of the device body;

[0074] an aerosol channel 31 formed in the nozzle 11;

[0076] A power supply assembly, disposed at the bottom of the atomizer 20, for providing power to the atomizer 20; and

[0077] The aerosol storage component 23 is disposed at the entrance of the aerosol passage 31 .

[0078] Since the atomizing device has all the technical features of the condensate storage component 23 provided in any of the above embodiments, it has the same technical effect as the above condensate storage component 23.

[0079] The above is a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
