Description

Technical Field

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

[0002] An electronic atomizing device is an electronic device that can vaporize stored e-liquid, medicinal liquid, or other atomizing liquid into vapor mist through electric heating or other means. An electronic atomizing device typically includes an atomizer and a power supply component. The atomizer generally includes a storage chamber for storing the atomizing liquid and an atomizing core for absorbing the atomizing liquid and vaporizing it into vapor mist. The power supply component is used to supply power to the atomizing core.

[0003] In related technologies, the liquid inlet of the atomizer coil is usually directly connected to the storage chamber. When the atomizer is placed flat, tilted, or inverted, leakage is likely to occur. This is because, when the atomizer is in these positions, at least part of the liquid inlet is exposed above the liquid surface and into the storage space of the storage chamber (i.e., at least part of the liquid inlet is not submerged in the liquid within the storage chamber). This allows the storage space of the storage chamber to connect with the atomizer's internal structure through the exposed liquid inlet and the atomizer coil. The air passages are connected (the internal air passages of the atomizer are connected to the external atmospheric environment), which causes the air pressure in the storage chamber to increase rapidly to the same level as atmospheric pressure. Thus, when the atomizer is then positioned so that the atomized liquid in the storage chamber once again submerges all the inlet holes, the atomized liquid in the storage chamber will accelerate through the inlet holes and be guided to the atomizer core under the combined effect of gravity and air pressure in the storage chamber. This makes it easy for the atomized liquid to leak out from the inlet holes or the atomizer core and into the internal air passages of the atomizer, causing a leakage problem.

[0004] The above content is merely the technology known only to the inventors of this application, and is only used to assist in understanding the technical solution of this application. It does not imply that the above content is prior art. Utility Model Content

The second housing is connected to the first housing, and the battery is electrically connected to the atomizing core.

[0025] Compared with the prior art, this application has at least the following beneficial effects:

[0026] In the technical solution provided in this application embodiment, by adding a corresponding liquid inlet hole and connecting it to the storage cavity and the liquid inlet hole respectively, and setting the size of the liquid inlet hole to 0.3-1mm, once the atomizing liquid in the storage cavity covers the position connecting the liquid inlet hole and the storage cavity, the atomizing liquid will be drawn into the liquid inlet hole by the capillary adsorption generated by the liquid inlet hole for storage and to cover the liquid inlet hole of the atomizing shell. Therefore, even if the atomizer is laid flat, tilted or inverted, the liquid inlet hole will still be stored due to the capillary adsorption of the liquid inlet hole. The atomizing liquid will not flow back into the storage space of the storage chamber, preventing the inlet port from being exposed above the liquid surface. The blocking effect of the atomizing liquid within the suction gap prevents the storage space above the liquid surface in the storage chamber from directly connecting to the air passages inside the atomizer shell via the inlet port and the atomizer core. This makes it difficult for the air pressure inside the storage chamber to increase to the same level as atmospheric pressure, effectively reducing the risk of leakage when the atomizer is properly positioned, due to increased air pressure within the storage chamber. Furthermore, since the atomizing liquid forms a liquid film within the narrow suction gap, the surface tension of this film slows down the speed at which the atomizing liquid is guided towards the inlet port, further reducing the risk of leakage.

[0059] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0061] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, top, bottom, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0063] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0064] Furthermore, if the terms "and / or," "and / or," or "and / or" appear throughout the text, their meaning includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Additionally, the specification of this application describes numerous technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, feature A+B+C is disclosed in one example, and feature A+B+D+E is disclosed in another example. Features C and D are equivalent technical means that serve the same purpose. Technically, only one of them needs to be used, and it is impossible to use them simultaneously. Feature E can be combined with feature C technically. Therefore, the solution A+B+C+D should not be considered as having been recorded because it is technically infeasible, while the solution A+B+C+E should be considered as having been recorded.

[0065] Please refer to Figure 3-4 , Figure 6 , Figure 11 , Figure 13 , Figure 16 and Figure 18 One embodiment of this application provides an atomizer 100, which includes a first housing 1 and an atomizing component 2, wherein:

[0066] The interior of the first housing 1 is provided with an inner wall 102 and a storage cavity 103 for storing atomizing liquid. The top of the first housing 1 is provided with a first installation channel 101 and the bottom of the first housing 1 is provided with a second installation channel 120.

[0067] The atomizing component 2 includes an atomizing core 21 and an atomizing shell 22. The atomizing shell 22 is hollow and has a through-hole forming an air passage 223. The atomizing core 21 is installed in the air passage 223. The upper port of the atomizing shell 22 is sealed and connected to the first mounting channel 101, and the lower port of the atomizing shell 22 is sealed and connected to the second mounting channel 120. The side wall of the atomizing shell 22 is provided with at least one liquid inlet hole 220 connected to the atomizing core 21. A liquid absorption gap 3 is formed between the side wall portion of the atomizing shell 22 with the liquid inlet hole 220 and the inner wall 102. The liquid absorption gap 3 is connected to the storage cavity 103 and the at least one liquid inlet hole 220, and the size of the liquid absorption gap 3 is 0.3mm to 1mm. Figure 3-4 , Figure 6 , Figure 13 , Figure 16 and Figure 18 As shown, assuming the size of the liquid absorption gap 3 is d, then 0.3mm ≤ d ≤ 1mm. In specific implementations, the size of the liquid absorption gap 3 can be 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., as long as it allows the liquid absorption gap 3 to generate capillary adsorption and forms a liquid film capable of generating surface tension within the liquid absorption gap 3 after the atomized liquid enters it. This embodiment does not impose specific limitations on the specific size of the liquid absorption gap 3. Furthermore, the size of the liquid absorption gap 3 can be uniformly distributed or non-uniformly distributed; this embodiment also does not impose specific limitations on this.

[0068] In this embodiment, based on the above structural design, by adding a corresponding liquid inlet hole 220 and connecting it to the storage cavity 103 and the liquid inlet hole 220 respectively, and setting the size of the liquid inlet hole 220 to 0.3-1mm, the atomizing liquid in the storage cavity 103 will be drawn into the liquid inlet hole 220 by the capillary adsorption generated by the liquid inlet hole 220 for storage and to cover the liquid inlet hole 220 of the atomizing shell 22, even if the atomizer 100 is laid flat, tilted or inverted, the liquid inlet hole 220 will still be drawn into the liquid inlet hole 220 by the capillary adsorption of the liquid inlet hole 220. The atomizing liquid will not flow back into the storage space of the storage cavity 103, thus preventing the inlet hole 220 from being exposed above the liquid surface. The atomizing liquid within the suction gap 3 acts as a barrier, preventing the storage space above the liquid surface in the storage cavity 103 from directly connecting to the air passage 223 inside the atomizing shell 22 via the inlet hole 220 and the atomizing core 21. This makes it difficult for the air pressure inside the storage cavity 103 to increase to the same level as atmospheric pressure, effectively reducing the risk of leakage when the atomizer 100 is properly aligned due to increased air pressure within the storage cavity 103. Furthermore, since the atomizing liquid forms a liquid film within the narrow suction gap 3, the surface tension of this film slows down the speed at which the atomizing liquid in the storage cavity 103 is guided towards the inlet hole 220, further reducing the risk of leakage.

[0069] Furthermore, in some specific application scenarios, to avoid excessive surface tension of the liquid film causing the atomizing liquid in the storage cavity 103 to be guided too slowly to the inlet hole 220, which could lead to insufficient liquid and dry burning of the atomizing core 21 during atomization, in some optional embodiments of this application, the size of the suction gap 3 is preferably 0.5mm to 1mm, and more preferably, the size of the suction gap 3 can be further set to 0.7mm to 0.9mm. This helps the atomizer 100 to achieve better anti-leakage and anti-dry burning effects. In this embodiment, it can be understood that during the atomization process of the atomizing core 21, the atomizing liquid in the suction gap 3 can be guided to the atomizing core 21 through the inlet hole 220 for atomization. At the same time, the suction gap 3 will absorb atomizing liquid from the storage cavity 103 to replenish it, thereby ensuring that the atomizing liquid in the storage cavity 103 can be continuously guided to the atomizing core 21 for atomization.

[0070] Furthermore, in some optional embodiments of this application, the storage cavity 103 and the liquid suction gap 3 can be formed by the following structural design:

[0071] Please refer to Figure 1-3 , Figure 5-8 as well as Figure 9-13 The first housing 1 includes an outer shell 11 and a base 12. An inner tube 15 is formed inside the top of the outer shell 11, and a first mounting channel 101 is formed inside the inner tube 15. The base 12 is sealed to the bottom of the outer shell 11 (exemplarily, the base 12 can be made of a flexible sealing material such as silicone, rubber, or silicone rubber, and the base 12 is at least partially sealed to the bottom of the outer shell 11, thereby achieving a sealed connection between the base 12 and the bottom of the outer shell 11, preventing leakage of the atomizing liquid through the mounting gap between the base 12 and the outer shell 11). A second mounting channel 120 is formed inside the base 12. The upper end of the atomizing shell 22 is sealed to the inner tube 15 (exemplarily, the atomizing liquid is sealed to the bottom of the outer shell 11). The device 100 also includes a sealing sleeve 5 made of flexible sealing material. The sealing sleeve 5 is hollow and has a through-hole structure. The upper end of the atomizing shell 22 and the inner tube 15 are sealed together by the sealing sleeve 5. The lower end of the atomizing shell 22 is sealed and fitted in the second mounting channel 120 of the base 12. The storage cavity 103 is defined by at least the outer shell 11, the atomizing shell 22 and the base 12. The top of the base 12 is provided with a gap member 4. The gap member 4 has an inner wall 102 provided on the side wall portion facing the atomizing shell 22 where the liquid inlet hole 220 is provided. That is, there is a gap of 0.3 to 1 mm between the side wall portion of the atomizing shell 22 where the liquid inlet hole 220 is provided and the inner wall 102 of the gap member 4 to form a liquid suction gap 3.

[0072] In this embodiment, it should be noted that, in specific implementation, the connection between the gap member 4 and the top of the base 12 can be an integral connection or an assembled connection, depending on the actual usage requirements. This embodiment does not impose specific limitations on this. In some optional embodiments, such as Figure 3 as well as Figure 6-8 As shown, when the connection between the gap member 4 and the top of the base 12 is an integral connection, both the base 12 and the gap member 4 can be made of flexible sealing material, and the gap member 4 and the base 12 can be integrally molded by injection molding or other methods. In some other optional embodiments, such as Figure 11 As shown, when the connection between the gap member 4 and the top of the base 12 is an assembly connection, the base 12 can be made of a flexible sealing material, and the gap member 4 can be made of a rigid material (such as plastic, metal, ceramic, etc.). The lower end of the gap member 4 is installed on the top of the base 12 by insertion. Preferably, the connection between the gap member 4 and the top of the base 12 is an integral connection, which helps to reduce the component cost and assembly cost of the atomizer 100.

[0073] Further, please refer to Figure 3 as well as Figure 6-8In some optional embodiments of this application, multiple liquid inlet holes 220 are provided, and the multiple liquid inlet holes 220 are arranged at intervals along the circumference of the atomizing shell 22. The gap member 4 is arranged around the atomizing shell 22 along the circumference of the atomizing shell 22, thereby forming an annular liquid absorption gap 3 between the inner wall 102 of the gap member 4 and the outer peripheral sidewall of the atomizing shell 22. In this way, by providing multiple liquid inlet holes 220, the efficiency of guiding the atomizing liquid to the atomizing core 21 can be improved, thereby reducing the risk of dry burning due to insufficient liquid when the atomizing core 21 is performing atomization. At the same time, the annular liquid absorption gap 3 can facilitate the atomizing liquid to enter the liquid absorption gap 3 for storage and cover each liquid inlet hole 220, so as to avoid the leakage problem of the atomizer 100. That is, it is beneficial to better balance the anti-leakage performance and anti-dry burning performance of the atomizer 100.

[0074] Further, please refer to Figure 3 , Figure 6-8 , Figure 11 and Figure 13 In some optional embodiments of this application, the base 12 has a top end face 121, which is the bottom wall of the storage cavity 103. The gap member 4 is connected to the top end face 121. The side wall of the gap member 4 is provided with a plurality of drainage notches 40 communicating with the liquid absorption gap 3. The plurality of drainage notches 40 are arranged at intervals along the circumference of the gap member 4. Each drainage notch 40 extends from the upper end face of the gap member 4 to at least the top end face 121. Along the circumference of the gap member 4, each drainage notch 40 has a first wall surface 41 and a second wall surface 42 that are arranged at relative intervals. The distance L between the first wall surface 41 and the second wall surface 42 is 0.8 mm to 1.1 mm. Moreover, along the height direction of the atomizing shell 22, the vertical distance h between the hole axis of at least one liquid inlet hole 220 and the top end face 121 is 0.1 mm to 2 mm.

[0075] In this embodiment, based on the above structural design, the atomizing liquid in the storage cavity 103 can be introduced into the liquid absorption gap 3 through the drainage notch 40 to the maximum extent. Moreover, the atomizing liquid in the liquid absorption gap 3 can be guided to the atomizing core 21 through the liquid inlet 220 to the maximum extent, thereby improving the utilization rate of the atomizing liquid. Specifically, by setting the distance L between the first wall surface 41 and the second wall surface 42 of the drainage notch 40 to 0.8mm to 1.1mm, it is not only ensured that the atomizing liquid on the top end face 121 of the base 12 can flow smoothly into the liquid absorption gap 3 through the drainage notch 40, but also that the drainage notch 40 is not set too large (i.e., the distance L is greater than 1.1mm), which would make it difficult for the atomizing liquid to remain in the liquid absorption gap 3 after entering the liquid absorption gap 3 and to form a liquid film in the liquid absorption gap 3.

[0076] Further, please refer to Figure 1-5 as well as Figure 9-12In some optional embodiments of this application, a mouthpiece 14 is formed on the top of the outer shell 11, and the mouthpiece 14 is integrally connected to the end of the inner tube 15 opposite to the atomizing shell 22. In this embodiment, the mouthpiece 14 is provided for easy inhalation by the user, and both the mouthpiece 14 and the inner tube 15 are integrally formed with the outer shell 11, which helps to reduce the component cost of the atomizer 100.

[0077] Furthermore, in some alternative embodiments of this application, the storage cavity 103 and the liquid suction gap 3 can also be formed by the following structural design:

[0078] Please refer to Figure 4 The first housing 1 includes an outer shell 11 and a base 12. An inner tube 15 is formed inside the top of the outer shell 11, and a first mounting channel 101 is formed inside the inner tube 15. The base 12 is sealed to the bottom of the outer shell 11 (exemplarily, the base 12 can be made of a flexible sealing material such as silicone, rubber, or silicone rubber, and the base 12 is at least partially sealed to the bottom of the outer shell 11, thereby achieving a sealed connection between the base 12 and the bottom of the outer shell 11). A second mounting channel 120 is formed inside the base 12. The second mounting channel 120 includes a first hole 1201 and a second hole 1202 that are connected sequentially from top to bottom. The diameter of the first hole 1201 is larger than that of the second hole 1202. The aperture of the first hole 1202 is such that the upper end of the atomizing shell 22 is sealed to the inner tube 15 (exemplarily, the atomizer 100 also includes a sealing sleeve 5 made of flexible sealing material, the sealing sleeve 5 is hollow and through, and the upper end of the atomizing shell 22 and the inner tube 15 are sealed to each other through the sealing sleeve 5), the lower end of the atomizing shell 22 is sealed to fit inside the second hole 1202, the storage cavity 103 is defined by at least the outer shell 11, the atomizing shell 22 and the base 12, and the inner peripheral wall of the first hole 1201 is the inner wall 102, that is, there is a gap of 0.3 to 1 mm between the side wall portion of the atomizing shell 22 with the liquid inlet hole 220 and the inner peripheral wall of the first hole 1201 to form a liquid absorption gap 3.

[0079] Further, please continue to refer to Figure 4 In some optional embodiments of this application, the base 12 has a top end face 121, which serves as the bottom wall of the storage cavity 103. The upper end opening of the first hole 1201 is located on the top end face 121. Along the height direction of the atomizing shell 22, the vertical distance between the axis of at least one liquid inlet hole 220 and the bottom wall of the first hole 1201 is 0.1 mm to 2 mm. This arrangement also allows the atomized liquid in the storage cavity 103 to be introduced into the liquid suction gap 3 to the maximum extent. Moreover, the atomized liquid in the liquid suction gap 3 can be guided to the atomizing core 21 through the liquid inlet hole 220 to the maximum extent, thereby improving the utilization rate of the atomized liquid.

[0080] In this embodiment, it should be noted that the atomizer 100 provided in this embodiment (e.g.) Figure 4 (as shown) and as Figure 3 The main difference between the atomizers 100 provided in the embodiments shown is that the atomizer 100 provided in this embodiment can form a liquid suction gap 3 without setting a gap member 4 on the top of the base 12.

[0081] Furthermore, in some optional embodiments of this application, the storage cavity 103 and the liquid suction gap 3 can also be formed by the following structural design:

[0082] Please refer to Figure 14-18 The first housing 1 includes an outer shell 11, a base 12, and a top cover 13. The top cover 13 is sealed to the top of the outer shell 11 (exemplarily, the top cover 13 may be made of a flexible sealing material such as silicone, rubber, or silicone rubber, and the top cover 13 is at least partially sealed to the top of the outer shell 11, thereby achieving a sealed connection between the top cover 13 and the top of the outer shell 11). A first mounting channel 101 is formed inside the top cover 13. The base 12 is sealed to the bottom of the outer shell 11 (exemplarily, a sealing connection between the two can be achieved by providing a sealing ring between the base 12 and the bottom of the outer shell 11). A second mounting channel 120 is formed inside the base 12. The atomizing shell 22 includes a first channel portion 221 and a second channel portion 222. The first channel portion 221... The outer diameter and inner diameter of the first pipe section 221 are both smaller than those of the second pipe section 222. The upper end of the first pipe section 221 is sealed and fitted into the first mounting channel 101. The lower end of the first pipe section 221 is connected to the upper end of the second pipe section 222 as a whole. The lower port of the second pipe section 222 is sealed and connected to the second mounting channel 120. At least one liquid inlet hole 220 is provided on the side wall of the second pipe section 222. The atomizing core 21 is installed in the second pipe section 222. The storage cavity 103 is defined by the outer shell 11, the top cover 13, the upper end face of the first pipe section 221 and the second pipe section 222. The inner peripheral wall of the outer shell 11 is the inner wall 102. That is, there is a gap of 0.3 to 1 mm between the outer peripheral side wall of the second pipe section 222 and the inner peripheral wall of the outer shell 11 to form a liquid absorption gap 3.

[0083] Further, please refer to Figure 3-4 , Figure 6 , Figure 11 , Figure 13 , Figure 16 and Figure 18 In some optional embodiments of this application, the atomizing component 2 further includes a liquid storage 23 made of porous material (such as fiber cotton, sponge, porous ceramic, etc.). The liquid storage 23 is hollow and has a through-hole arrangement. The liquid storage 23 is installed inside the atomizing shell 22 and covers each liquid inlet 220. The atomizing core 21 is installed inside the liquid storage 23 and is connected to the liquid storage 23.

[0084] In this embodiment, based on the above structural design, the liquid storage 23 can adsorb the atomizing liquid in the liquid absorption gap 3 through capillary action and transfer the atomizing liquid it adsorbs to the atomizing core 21 for atomization. This is equivalent to the liquid storage 23 acting as a buffer for the atomizing liquid guiding the atomizing core 21. Thus, under the buffering effect of the liquid storage 23, the atomizing liquid can be guided to the atomizing core 21 at a more suitable rate, thereby improving the leakage prevention and dry-burning prevention performance of the atomizer 100.

[0085] Furthermore, in some optional embodiments of this application, the structural form of the atomizing core 21 and the communication method between the atomizing core 21 and the liquid storage 23 can be as follows:

[0086] Please refer to Figure 16 and Figure 18 The atomizing component 2 also includes a support sleeve 24. The atomizing core 21 includes a heating element 211 made of metal and a liquid guide 212 made of porous material (such as fiber cotton, sponge, porous ceramic, etc.). At least one liquid passage hole 240 is provided on the side wall of the support sleeve 24. The support sleeve 24 is at least partially inserted into the interior of the liquid storage 23. The liquid guide 212 is hollow and has a through-hole. The liquid guide 212 is at least partially inserted into the interior of the support sleeve 24. The liquid storage 23 and the liquid guide 212 both cover at least one liquid passage hole 240 (that is, the atomizing core 21 and the liquid storage 23 can be connected through the liquid passage hole 240 of the support sleeve 24). The heating element 211 is connected to the inner peripheral wall of the liquid guide 212.

[0087] Correspondingly, please refer to Figure 19-21 This application also provides an electronic atomizing device, which includes a power supply assembly 200 and an atomizer 100 as described in any of the above embodiments. The power supply assembly 200 includes a second housing 6 and a battery 7 installed in the second housing 6. The second housing 6 is connected to the first housing 1, and the battery 7 is electrically connected to the atomizing core 21.

[0088] In this embodiment, it should be noted that, in specific implementation, the connection between the first housing 1 and the second housing 6 can be a detachable connection (such as a magnetic connection, plug-in connection, snap-fit ​​connection, etc.) or a non-detachable connection (such as ultrasonic welding, hot melt adhesive bonding, etc.), which can be determined according to actual usage needs, and this embodiment does not impose specific limitations on this. Furthermore, the second housing 6 can be an integral structure or a split structure assembled from different housing structures, and this embodiment also does not impose specific limitations on this.

[0089] In this embodiment, thanks to the improvement of the atomizer 100, the electronic atomizing device provided in this embodiment has the same technical effect as the atomizer 100, which will not be described again here.

[0090] It should be noted that other aspects of the atomizer 100 and electronic atomizing device disclosed in this application that are not described in detail can be found in the prior art, and will not be repeated here.
