Description

Technical Field

[0001] This utility model relates to the field of incense burner technology, and in particular to an atomizer and an electronic incense burner. Background Technology

[0002] With the increasing popularity of electronic incense burners, users are demanding higher and higher user experience. Electronic incense burners often produce smoke that simulates burning incense sticks by heating incense liquid. However, existing electronic incense burners face the risk of incense liquid leakage during long-term use. If the incense liquid is not fully atomized, it will be dispersed with the smoke, causing a large number of e-liquid particles to spread outward.

[0038] Please refer to Figures 1 to 4As shown, this utility model proposes an atomizer 100, which is provided with a reflux chamber 1a, which is connected to an external space; the atomizer 100 also includes an atomizing component 2, which includes a liquid storage component 21 and an atomizing component. The liquid storage component 21 is configured to store the atomizing medium, and the atomizing component is configured to draw in the atomizing medium from the liquid storage component 21 and form smoke; wherein, the liquid storage component 21 is in fluid communication with the reflux chamber 1a, and the atomizing component is in air passage communication with the reflux chamber 1a.

[0039] In this embodiment, the atomizer 100 is a device capable of generating smoke or water mist. The atomizer 100 can be applied to fields such as electronic incense burners 500, humidifiers, and electronic cigarettes. The housing 1 of the atomizer 100 can be a metal housing 1 or a plastic housing 1. The housing 1 has a cylindrical or prismatic structure, or an irregular shape. The atomizer 100 may be provided with a housing 1, which forms an inner cavity 13, so that the atomizing component 2 is disposed within the inner cavity 13.

[0040] The atomizing component 2 includes a liquid storage element 21 and an atomizing element. The liquid storage element 21 is a liquid storage structure made of porous ceramic material, used to store water-based or oil-based atomizing media. The liquid storage element 21 surrounds the atomizing element. The atomizing element includes a liquid guiding element 22 and a heating element. The liquid guiding element 22 is a liquid guiding structure made of porous metal material. The heating element is disposed on the liquid guiding element 22, such as being disposed inside or outside the liquid guiding element 22.

[0041] Specifically, the liquid guiding component 22 has a structure with guide holes or channels. A heating element is provided inside the liquid guiding component 22. The heating element is a heating wire or a heating mesh. The liquid guiding component 22 can stably draw (absorb) the atomizing medium from the liquid storage component 21 containing oil through capillary action or gravity and deliver it to the heating element so that the heating element heats the atomizing medium to generate smoke.

[0042] Meanwhile, the atomizer 100 is provided with a reflux chamber 1a. The reflux chamber 1a can be an independent cavity structure formed by the shell 1 of the atomizer 100, or it can be the space formed between the atomizing component 2 and the main body 31 of the atomizer 100. The reflux chamber 1a is connected to the gas path of the atomizing component, and the liquid storage component 21 is fluidly connected to the atomizing component. The reflux chamber 1a is also connected to the external space. The setting of the reflux chamber 1a forms an independent pressure regulation space, and the dynamic balance of the gas-liquid two-phase flow is controlled by physical isolation.

[0043] It is understandable that the gas-liquid separation of the atomizing medium is not complete during the high-temperature vaporization process, and there are still a large number of un-atomized liquid particles or aerogel particles. These aerogel particles will diffuse into the external space with the smoke flow, which will not only cause oil fumes to pollute the environment and the electronic incense burner 500, but also increase the consumption of oil. In this application, the atomizing component has a smoke channel 221 for generating and dispersing smoke. The smoke channel 221 is connected to the return chamber 1a so that after the smoke is generated by heating, the smoke enters the return chamber 1a. The smoke entering the return chamber 1a will not be directly discharged into the external space, but will accumulate in the return chamber 1a so that the return chamber 1a provides reserved space for the smoke, increasing the retention time of the smoke in the inner cavity 13. During the retention process, due to the decrease in temperature, the un-vaporized droplets can still be re-condensed into liquid and recycled back to the atomizing component 2 to participate in atomization again.

[0044] Based on the above embodiments, furthermore, the liquid storage component 21 in the atomizing component 2 is in fluid communication with the return chamber 1a, such as through a channel or pipe structure, or the liquid storage component 21 is directly exposed at the bottom of the return chamber 1a, etc., without limitation. This design allows the droplets that are not completely vaporized after atomization to flow back into the liquid storage component 21 through gravity or capillary action. This not only prevents the smoke from flowing directly to the outside, but also improves the atomization efficiency, thereby increasing the repeated evaporation of e-liquid and allowing some of the e-liquid to flow back into the atomizing component 2, reducing the rapid evaporation of e-liquid, so as to reduce the leakage and waste of e-liquid.

[0045] Through the above solution, this application achieves efficient utilization and circulation of the atomizing medium. The setting of the reflux chamber 1a effectively prevents incompletely atomized liquid particles from leaking out with the smoke, avoiding waste of the atomizing medium and equipment pollution. This structural design significantly improves the user experience of the electronic incense burner 500, extends the service life of the equipment, and improves product performance and reliability.

[0046] In one implementation, such as Figure 1 and Figure 4 As shown, the atomizing component includes a liquid guiding component 22 and a heating component. The liquid storage component 21 surrounds and abuts against the liquid guiding component 22. The liquid guiding component 22 is provided with a smoke channel 221, which is connected to the air passage of the return chamber 1a. The heating component is located in the smoke channel 221.

[0047] In this embodiment, the liquid guiding component 22 forms a smoke channel 221, which is connected to the air passage of the return chamber 1a. The liquid guiding component 22 can be made of porous ceramic material or have a channel or pipe structure. The liquid guiding component 22 has a through smoke channel 221 in its center. The liquid storage component 21 wraps around and tightly abuts against the outer periphery of the liquid guiding component 22. The liquid guiding component 22 can guide or draw the oil in the liquid storage component 21 into the interior. The heating element is a metal wire ring or metal mesh, which is fixed on the inner wall of the smoke channel 221. The atomizing medium in the liquid storage component 21 is absorbed by the liquid guiding component 22 through capillary action. When the heating element is energized, it generates heat, which directly acts on the atomizing medium flowing through the smoke channel 221, causing it to vaporize instantly and form smoke particles. The smoke enters the return chamber 1a through the smoke channel 221 and is then discharged from the return chamber 1a.

[0048] It is understandable that the liquid storage component 21 forms a closed liquid guiding environment by surrounding the liquid guiding component 22, preventing lateral leakage of the atomizing medium during transportation. The through-type design of the smoke channel 221 inside the liquid guiding component 22 creates negative pressure in the airflow within the channel, accelerating the migration of the atomizing medium to the surface of the heating element. The vaporized smoke enters the return chamber 1a with the airflow to complete secondary mixing and retention. The incompletely atomized liquid medium condenses on the inner wall of the channel and returns to the liquid storage component 21, which is connected to the liquid in the return chamber 1a, forming a cycle. This structure, through the combination of directional airflow and local heating, confines the atomization process within a closed channel, effectively reducing the leakage of liquid medium. Thus, this application solves the problems of insufficient atomization and leakage of e-liquid particles in the prior art, improving the performance of the electronic incense burner 500.

[0049] In one implementation, such as Figure 1 As shown, the atomizer 100 is also provided with a mounting cavity 1b, which is connected to the return cavity 1a; the atomizing component 2 is located in the mounting cavity 1b, and the side of the liquid storage component 21 facing the return cavity 1a is exposed in the return cavity 1a so that the liquid storage component 21 is in fluid communication with the return cavity 1a.

[0050] In this embodiment, the mounting cavity 1b can be a chamber formed by the housing 1 of the atomizer 100 itself, or a separate chamber formed by an external structure. The atomizing component 2 is disposed in the mounting cavity 1b, and the mounting cavity 1b is connected to the return cavity 1a. After the liquid storage component 21 is fixed in the mounting cavity 1b, its top surface is directly exposed to the bottom area of ​​the return cavity 1a or is fluidly connected to the return cavity 1a through a pipe or channel. The smoke channel 221 formed by the liquid guiding component 22 is also directly connected to the return cavity 1a through the air passage.

[0051] Through the above technical solution, this application achieves effective communication between the atomizing component 2 and the return chamber 1a. The smoke in the smoke channel 221 can directly enter the return chamber 1a and gather and remain in the return chamber 1a. The incompletely atomized droplets will re-condense and can be directly absorbed by the liquid storage component 21. This structural design simplifies the internal structure of the atomizer 100, improves the atomization efficiency, and also facilitates the collection and reuse of the return liquid, reducing liquid waste. In addition, this design also facilitates the installation and maintenance of the atomizing component 2, improving the practicality and reliability of the product.

[0052] In one implementation, such as Figure 1 As shown, the reflux chamber 1a is located above the liquid storage component 21 and the atomizing component; optionally, the fluid communication point between the liquid storage component 21 and the reflux chamber 1a is located at the bottom of the reflux chamber 1a in the vertical direction.

[0053] In this embodiment, based on the upward flow of smoke, the return chamber 1a is located above the liquid storage component 21 and the atomizing component to better accumulate smoke above the atomizing component 2 and allow the smoke to flow back into the atomizing component 2 as much as possible during its retention in this space. The vertical layout places the liquid storage component 21 below the return chamber 1a. Driven by gravity, the liquid flows downwards along the connection point, and gravity guides the un-atomized liquid to fall naturally, allowing it to flow back from the return chamber 1a into the liquid storage component 21, forming a one-way liquid return path. Furthermore, the return chamber 1a is located above the atomizing component, allowing the smoke inside to flow upwards into the return chamber 1a.

[0054] Understandably, after the atomizing element heats up and generates smoke, the smoke flows upward into the return chamber 1a. When the incompletely atomized liquid generated by the atomizing element enters the return chamber 1a, it automatically sinks to the bottom of the chamber due to gravity. The connecting port at the bottom guides the liquid directionally into the liquid storage unit 21, where it is reabsorbed by the unit through capillary action. The vertical layout forms a top-down liquid circulation path, and the atomizing medium forms a closed-loop flow between the return chamber 1a and the liquid storage unit 21, further ensuring the smoothness of liquid return. This structure effectively prevents liquid from accumulating at the top of the return chamber 1a, eliminates the possibility of liquid overflowing through the smoke guide hole 112, avoids liquid waste, and ensures that the liquid storage unit 21 is continuously replenished with atomizing medium. This design not only improves the efficiency of the atomizer 100 but also reduces the risk of liquid leakage, improving the user experience.

[0055] In one implementation, such as Figure 1 and Figure 4 As shown, the atomizer 100 is also provided with a smoke guide hole 112, which connects the return chamber 1a and the external space. The smoke guide hole 112 is located at the bottom of the return chamber 1a in the vertical direction adjacent to the liquid storage component 21.

[0056] In this embodiment, the smoke guide hole 112 connects the return cavity 1a and the external space. The smoke guide hole 112 is used to guide the atomized smoke in the return cavity 1a to the outside to form smoke that simulates the burning of a traditional incense stick. The smoke guide hole 112 is located in the bottom area of ​​the return cavity 1a and close to the oil storage component installation position. This position is at the end of the smoke flow path. The smoke guide hole 112 penetrates the inside and outside of the housing 1 to form a gas exchange channel.

[0057] Understandably, the smoke guide hole 112 is located at the bottom of the return cavity 1a near the liquid storage component 21. On the one hand, it can create more space in the upper part of the return cavity 1a to collect smoke. On the other hand, when the smoke generated by the atomizing component enters the return cavity 1a, the smoke generates a longer smoke flow path when it enters the smoke guide hole 112 from the return cavity 1a. This causes the denser smoke particles to settle to the bottom of the cavity under the action of gravity and flow back to the liquid storage component 21, thereby improving the condensation and reflux effect of the incompletely atomized droplets in the smoke and improving the oil recovery rate.

[0058] In one implementation, such as Figure 1 , Figure 2 as well as Figure 4 As shown, the atomizer 100 also includes a housing 1 and a sealing structure 3. The housing 1 forms an inner cavity 13, which includes a reflux cavity 1a and a mounting cavity 1b. The atomizing component 2 and the sealing structure 3 are disposed in the mounting cavity 1b. The sealing structure 3 abuts against the cavity wall of the mounting cavity 1b. The sealing structure 3 and the reflux cavity 1a are located at both ends of the liquid storage component 21 in the vertical direction.

[0059] In this embodiment, the atomizer 100 further includes a housing 1, which serves as a support structure for the main body 31 of the atomizer 100. The housing 1 forms an inner cavity 13, and the inner cavity 13 includes a mounting cavity 1b for placing and mounting the atomizing component 2. In another embodiment, the inner cavity 13 also includes the aforementioned reflux cavity 1a, which communicates with the mounting cavity 1b. The housing 1 can be integrally formed or detachably connected in parts, which is not limited here. In addition, the housing 1 also has a through hole 121, which connects the mounting cavity 1b and the external space. A conductive element 23 is installed at the through hole 121, and the conductive element 23 is electrically connected to the heating element and the external circuit.

[0060] In this embodiment, the atomizer 100 further includes a sealing structure 3. The sealing structure 3 can be made of silicone, rubber, or other elastic materials. The sealing structure 3 is disposed in the inner cavity 13 and located between the atomizing component 2 and the through hole 121. It surrounds the conductive component 23 and seals against the liquid storage component 21. Through elastic deformation, it tightly covers the conductive component 23, preventing the liquid from leaking from the through hole 121. The sealing structure 3 is disposed at the through hole 121 to seal the gap between the conductive component 23 and the inner wall of the through hole 121. In addition to surrounding the through hole 121, the sealing structure 3 can also surround part of the liquid guiding component 22 and the heating component. The sealing structure 3 includes, but is not limited to, structures such as sealing gaskets, sealing rings, sealing seats, and sealing rings. The sealing component in the sealing structure 3 can be made of materials such as silicone or rubber. Specifically, a silicone ring or a rubber gasket can be nested around the through hole 121 to block the path of liquid leakage from the inner cavity 13 through the through hole 121.

[0061] Understandably, after installing the atomizing component 2, the inner cavity 13 of the housing 1 needs to supply power to the heating element through the through hole 121 so that it can heat the atomizing medium to produce smoke. However, the oil stored in the liquid storage component 21 will inevitably leak at the through hole 121, causing oil leakage and contamination of the product. By setting a sealing structure 3 between the through hole 121 and the liquid storage component 21, the leakage path of the atomizing liquid through the through hole 121 is blocked. When the atomizer 100 is working, the atomizing liquid is confined in the inner cavity 13 and will not leak to the outside through the through hole 121. At the same time, the sealing structure 3 also prevents external impurities from entering the inner cavity 13 through the through hole 121, ensuring the cleanliness of the atomization process.

[0062] Meanwhile, the sealing structure 3 and the return cavity 1a are located at both ends of the liquid storage component 21 in the vertical direction. The sealing structure 3 forms a physical isolation barrier between the guide hole 121 and the atomizing component 2 to effectively prevent oil from leaking outward from the guide hole 121. At the same time, combined with the spaced layout of the housing 1 and the atomizing component 2, the smoke can flow upward to the return cavity 1a, so that the droplets that are not completely vaporized after atomization can flow back to the bottom. This not only prevents the smoke from flowing directly to the outside, but also improves the atomization efficiency and reduces oil leakage. It effectively prevents leakage problems caused by tilting, vibration or high temperature, and improves the sealing reliability.

[0063] It is understood that this application forms a double sealing structure 3 by setting a sealing structure 3 between the atomizing component 2 and the through hole 121, and by having the oil-guiding cotton seal against the sealing structure 3. This structure can effectively prevent the fragrance liquid from leaking from the through hole 121, and maintain a good sealing effect even during long-term use or when the device is tilted. At the same time, the side of the oil-guiding cotton facing away from the through hole 121 is exposed to the return cavity 1a, which can reabsorb the incompletely atomized fragrance liquid, improving the utilization rate of the fragrance liquid and reducing waste. In addition, the sealing structure 3 is arranged around the conductive component 23, which not only plays a sealing role, but also prevents the conductive component 23 from directly contacting other components, improving the safety of the device. This design not only solves the fragrance liquid leakage problem existing in traditional electronic incense burners 500, but also improves the fragrance liquid utilization efficiency, thereby significantly improving the user experience and performance of the electronic incense burner 500.

[0064] Based on the characteristics of smoke flowing upward and oil flowing downward due to gravity, a return chamber 1a is provided at the upper part of the atomizing component 2 and a sealing structure 3 is provided at the lower part of the atomizing component 2. On the one hand, the smoke is accumulated to improve the return effect of the un-atomized smoke, and on the other hand, the liquid is prevented from leaking through the guide hole 121 at the bottom, thereby effectively enhancing the sealing effect of the atomizer 100.

[0065] In one implementation, such as Figure 1 and Figure 2 As shown, the sealing structure 3 includes a main body 31 and a plurality of annular protrusions 32. The plurality of annular protrusions 32 are arranged in parallel at intervals around the periphery of the main body 31, and the annular protrusions 32 seal against the cavity wall of the mounting cavity 1b.

[0066] In this embodiment, the main body 31 serves as a support structure for the sealing structure 3 to support the distribution of the annular protrusions 32. The sealing structure 3 forms a physical barrier through the contact between the main body 31 and the cavity wall. Multiple annular protrusions 32 are distributed parallel to each other along the periphery of the main body 31. The annular protrusions 32 extend axially to form an annular sealing surface, and a gap area is formed between adjacent protrusions. The contact pressure of the sealing interface is enhanced by the elastic deformation of the annular protrusions 32.

[0067] Specifically, the cavity wall of the mounting cavity 1b and the sealing structure 3 achieve dynamic sealing through a multi-layer sealing interface of annular protrusions 32, which can adapt to cavity deformation caused by temperature changes. The oil-guiding cotton is pressed and fixed in the vertical direction by the sealing structure 3 to prevent lateral displacement that could lead to seal failure. The return cavity 1a forms a continuous fluid channel through the space between the oil-guiding cotton and the cavity wall, allowing unatomized liquid to flow back to the storage area along the surface of the oil-guiding cotton. The vertical distribution design of the sealing structure 3 and the return cavity 1a allows the liquid under gravity to naturally sink to the storage component 21, while the smoke is discharged upward through the return cavity 1a, achieving gas-liquid path separation. The single-sided sealing cooperation between the oil-guiding cotton and the sealing structure 3 ensures the storage capacity while preventing liquid from seeping into other areas of the mounting cavity 1b.

[0068] Understandably, multiple protrusions form a stepped sealing layer. Under axial pressure, each protrusion deforms sequentially, and the gap area can accommodate material expansion caused by temperature changes. For example, when the sealing capacity of the first protrusion decreases due to wear, subsequent protrusions can still maintain an effective sealing interface. The arrangement of multiple annular protrusions 32 increases the contact area between the sealing structure 3 and the cavity wall of the mounting cavity 1b, improving the reliability of the seal. Even if a certain annular protrusion 32 experiences local sealing failure, the other annular protrusions 32 can still maintain the sealing effect, effectively preventing leakage of atomized media. At the same time, the elastic deformation of the annular protrusions 32 can adapt to the slight unevenness of the cavity wall of the mounting cavity 1b, further enhancing the sealing effect. In addition, the arrangement of multiple annular protrusions 32 can also disperse the sealing pressure and extend the service life of the sealing structure 3.

[0069] In one implementation, such as Figure 1 As shown, the liquid storage component 21 is an oil-guiding cotton, which is located between the return cavity 1a and the sealing structure 3. The oil-guiding cotton seals and abuts against the sealing structure 3 on one side along the vertical direction, and the oil-guiding cotton is spaced apart from the cavity wall of the inner cavity 13 on the other side along the vertical direction to form the return cavity 1a.

[0070] In this embodiment, the oil-wicking cotton can be made of porous materials such as cotton fiber, glass fiber, or porous ceramic fiber, which has good oil absorption and conduction properties. The oil-wicking cotton wraps around the liquid-conducting component 22 and the heating component, which can fully absorb and conduct the fragrance liquid, ensuring that the fragrance liquid is heated and atomized evenly. The oil-wicking cotton is set to wrap around and cover the heating component, ensuring that the heating area of ​​the heating component is completely wrapped. A certain amount of oil is stored in the oil-wicking cotton to transport the oil to the heating component. The thickness direction of the oil-wicking cotton is consistent with the vertical direction, and the bottom plane and the top plane of the sealing structure 3 form a surface contact seal through elastic compression.

[0071] Specifically, the oil-guiding cotton, through the deformation force generated by elastic compression, fits tightly with the sealing structure 3, blocking the path of the atomizing medium to penetrate downwards in the vertical direction. The gap between the top of the oil-guiding cotton and the cavity wall of the inner cavity 13 forms a reflux cavity 1a. The side of the oil-guiding cotton opposite to the guide hole 121 is completely exposed to the reflux cavity 1a, allowing the droplets that are not completely vaporized after atomization to flow back, thereby increasing the repeated evaporation of e-liquid and allowing some of the oil to flow back to the oil-guiding cotton. Furthermore, the oil can be evenly penetrated to the surface of the heating element through the capillary action of the oil-guiding cotton, allowing the un-atomized liquid to flow back into the oil-guiding cotton through the gap under the action of gravity.

[0072] Through the above technical solution, this application effectively prevents leakage of the atomizing medium in the vertical direction. The interference fit between the sealing structure 3 and the oil-guiding cotton forms a physical barrier layer, preventing liquid from entering the return cavity 1a through the assembly gap. The spacing design between the bottom of the oil-guiding cotton and the cavity wall promotes the natural return of the un-atomized medium under the action of gravity, reducing the accumulation of residual liquid.

[0073] Optionally, such as Figure 1 and Figure 3 As shown, the atomizing component 2 also includes a conductive element 23, which is electrically connected to the atomizing component and the external circuit. The sealing structure 3 surrounds and seals against the conductive element 23. Optionally, the atomizer 100 also includes an outer seal 4. The housing 1 has a mounting hole 14 on the side facing away from the inner cavity 13. The outer seal 4 is located in the mounting hole 14 and is configured to be connected to the external circuit.

[0074] In this embodiment, the conductive element 23 can be made of a metal material, such as copper, aluminum, or stainless steel, which have good electrical conductivity. One end of the conductive element 23 extends into the through hole 121 and connects to the external circuit, while the other end extends into the inner cavity 13 and is electrically connected to the heating element. The heating element can be a resistance wire or a metal sheet, etc., which generates heat when energized. If the conductive element 23 is a conductive terminal, it supplies power to the heating element to generate heat, which in turn heats the surrounding oil to produce smoke.

[0075] Meanwhile, the conductive element 23 is embedded in the through hole 121, and the sealing structure 3 is arranged around the conductive element 23. The sealing structure 3 forms a surrounding sealing structure 3 for the through hole 121 and the conductive element 23. The conductive element 23 extends away from the through hole 121 and seals the side of the oil-wicking cotton facing the through hole 121 by sealing against the sealing structure 3, thus preventing liquid from seeping out along the surface of the conductive element 23. At the same time, the side of the oil-wicking cotton facing the through hole 121 forms a planar seal by sealing against the sealing structure 3, while the side facing away from the through hole 121 is directly exposed to the return cavity 1a, which facilitates the fragrance liquid to enter the interior of the oil-wicking cotton through the return cavity 1a.

[0076] In another embodiment of the present invention, the housing 1 is further provided with a mounting hole 14, and an outer sealing member 4 is provided in the mounting hole 14. The outer sealing member 4 surrounds and forms a sealing slot 41. The sealing slot 41 is located on the side of the through hole 121 facing away from the inner cavity 13. The sealing slot 41 is configured to connect with the external circuit and seal the through hole 121.

[0077] The mounting hole 14 is located on the housing 1 and coaxially corresponds to the through hole 121. The outer seal 4 is embedded in the mounting hole 14, forming a sealing slot 41 inside. The opening of the sealing slot 41 faces away from the inner cavity 13. The size of the sealing slot 41 matches the plug-in terminal of the external circuit. When the plug-in terminal is inserted into the sealing slot 41, the inner wall of the outer seal 4 fits tightly against the plug-in terminal. The sealing structure 3 and the outer seal 4 form a double seal for the through hole 121 from the inner cavity 13 side and the outer side, respectively.

[0078] Furthermore, the outer seal 4 wraps around the plug-in terminal of the external circuit through the sealing slot 41. When the plug-in terminal is inserted, the inner wall of the sealing slot 41 is deformed by pressure, forming a radial seal and blocking the communication path between the external environment and the through hole 121. The coaxial design of the mounting hole 14 and the through hole 121 ensures the alignment accuracy between the plug-in terminal and the conductive part, avoiding seal failure due to misalignment. The sealing structure 3 and the outer seal 4 form complementary seals in the axial and radial directions. Even if the equipment is tilted or vibrates, the double sealing structure 3 can still maintain the stability of the sealing interface and prevent the fragrance liquid from leaking in high temperature or corrosive environments.

[0079] It is understood that, through the above technical solution, this application achieves double sealing protection for the through hole 121 of the atomizer 100. The sealing structure 3 is arranged around the conductive part, which effectively prevents the liquid in the inner cavity 13 from leaking through the gap between the conductive part and the through hole 121. The sealing slot 41 formed by the outer sealing member 4 not only facilitates the connection of the external circuit, but also further seals the through hole 121 to prevent external liquid or impurities from entering the inner cavity 13. This double sealing structure 3 significantly improves the sealing performance of the atomizer 100, effectively solves the liquid leakage problem that may occur during long-term use or accidental tilting, and improves the safety and reliability of the product.

[0080] In one implementation, such as Figure 1 and Figure 4 As shown, the housing 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 has a mounting opening 111 and a relief groove at the mounting opening 111. The lower shell 12 is inserted into the relief groove and abuts against the groove wall, so that the lower shell 12 and the upper shell 11 enclose an inner cavity 13. The lower shell 12 forms a through hole 121. The sealing structure 3 is provided on the lower shell 12 and simultaneously seals the groove wall of the relief groove and the lower shell 12.

[0081] In this embodiment, the upper shell 11 and the lower shell 12 are combined to form the shell 1, and the upper shell 11 and the lower shell 12 enclose an inner cavity 13 to accommodate the internal oil-guiding cotton, conductive component 23, heating component, and sealing structure 3. The upper shell 11 and the lower shell 12 can be fastened by snaps or inserted by plugging, which is not limited here. The upper shell 11 and the lower shell 12 can be injection molded from plastic material. The upper shell 11 has a mounting opening 111, which is a one-way opening, and the mounting opening 111 is located on the upper shell 1. At the bottom of 1, the relief groove is arranged in a ring around the periphery of the mounting port 111 and is recessed inward to form a groove. The outer circumferential dimension of the lower shell 12 matches the inner circumferential dimension of the relief groove, so that the lower shell 12 can be inserted into the relief groove. The upper shell 11 and the lower shell 12 are connected by the relief groove so that the outer circumferential wall of the lower shell 12 is tightly fitted with the inner wall of the relief groove. Of course, the lower shell 12 and the upper shell 11 can also be connected by a snap-fit ​​structure. The through hole 121 is located at the center of the lower shell 12 and is used to accommodate the conductive part 23 of the atomizing component 2.

[0082] Simultaneously, the sealing structure 3 is arranged in the contact area between the lower shell 12 and the relief groove, covering both the surface of the lower shell 12 and the groove wall surface. The material of the sealing structure 3 can be a high-temperature resistant elastomer, whose cross-sectional shape matches the gap of the relief groove. Under pressure, it deforms to fill the tiny gaps between the contact surfaces. The position of the through hole 121 formed in the lower shell 12 corresponds to the insertion direction of the relief groove, so that the through hole 121 communicates with the inner cavity 13 after assembly. During assembly, the flange of the lower shell 12 is inserted along the axial direction of the relief groove until the outer wall of the flange is completely fitted with the groove wall. At this time, the sealing structure 3 is compressed between the outer wall of the flange and the groove wall. The double sealing effect of the sealing structure 3 acts on the radial surface of the groove wall and the axial end face of the lower shell 12, forming a multi-directional sealing barrier. When the external circuit is connected through the through hole 121, the sealing structure 3 can prevent the fragrance liquid from seeping out along the gap between the through hole 121 and the circuit interface, and prevent the fragrance liquid from seeping out from the connection between the lower shell 12 and the upper shell 11. Under conditions of equipment tilting or vibration, the rigid contact of the plug-in structure, combined with the deformation compensation of the elastic seal, can maintain the stability of the sealing interface and avoid the risk of leakage caused by component displacement.

[0083] Understandably, by providing a clearance groove on the upper shell 11, the lower shell 12 can connect to the upper shell 11 from within, forming a well-sealed inner cavity 13. This also facilitates the installation and placement of the atomizing component 2 and the sealing structure 3. Furthermore, the sealing structure 3 is positioned between the upper shell 11 and the lower shell 12, ensuring a secure seal between the sealing structure 3 and both the clearance groove of the upper shell 11 and the lower shell 12, thus forming a reliable seal. This prevents leakage or seepage of the fragrance liquid from the connection between the upper shell 11 and the lower shell 12, improving the sealing performance of the atomizer 100. The sealing structure 3 also seals the through-hole 121 located in the lower shell 12, preventing the fragrance liquid from seeping out from the gap at the connection between the conductive component 23 and the through-hole 121. Moreover, since the sealing structure 3 is confined within the clearance groove, it is less prone to detachment, ensuring long-term reliability. In addition, this structural design is simple, easy to assemble, and beneficial for improving the production efficiency of the atomizer 100.

[0084] In one implementation, such as Figure 2 As shown, the sealing structure 3 includes a first sealing part 33 and a second sealing part 34. The first sealing part 33 extends into the relief groove to seal against the groove wall of the relief groove; a portion of the lower shell 12 protrudes from the relief groove and seals against the second sealing part 34.

[0085] In this embodiment, the first sealing part 33 and the second sealing part 34 can be an integrally formed structure or a separate assembly structure, such as being connected by plug-in or snap-fit. The first sealing part 33 is disposed at the assembly interface between the upper shell 11 and the lower shell 12, and the sealing structure 3 extends into the relief groove to simultaneously abut against the groove wall of the relief groove and the lower shell 12. The second sealing part 34 is disposed on the exposed part of the lower shell 12 and abuts against the side wall of the inner cavity 13 formed by the lower shell 12, that is, the second sealing part 34 covers the bottom of the inner cavity 13.

[0086] Specifically, during the assembly of the housing 1, when the lower housing 12 is inserted into the relief groove of the upper housing 11, the first sealing part 33 is embedded in the annular gap between the groove wall and the lower housing 12. By extending into the relief groove, a circumferential seal is achieved at the connection between the upper housing 11 and the lower housing 12. After the lower housing 12 is assembled, part of its housing 1 structure protrudes outside the relief groove. At this time, the second sealing part 34 surrounds the outer surface of the lower housing 12 and seals the through hole 121 and the like through axial compression deformation. The first sealing part 33 and the second sealing part 34 form an orthogonal sealing direction. The first sealing part 33 blocks the liquid flowing to the surroundings, and the second sealing part 34 prevents the liquid from penetrating in the direction of the through hole 121.

[0087] It is understood that, through the above technical solution, this application utilizes the first sealing part 33 and the second sealing part 34 to generate gradient elastic compression during axial assembly. The first sealing part 33 forms a dynamic compensation seal in the relief groove, effectively absorbing the assembly error of the housing 1. The second sealing part 34 forms a multi-point contact seal on the surface of the lower housing 12, enhancing the ability to block the liquid penetration path. When the equipment vibrates or the temperature changes, this structure maintains a stable sealing pressure through the adaptive deformation of the elastomer, preventing capillary leakage of the fragrance liquid along the joint of the housing 1. At the same time, the second annular protrusion 32 with a trapezoidal cross section generates a uniform stress distribution under contact pressure, avoiding sealing failure caused by plastic deformation of the sealing material during long-term use.

[0088] In one embodiment, the first sealing part 33 includes a first body 31 and a plurality of first annular protrusions 32, the plurality of first annular protrusions 32 being arranged in parallel at intervals around the periphery of the first body 31, and the first annular protrusions 32 sealingly abutting against the groove wall of the relief groove; optionally, the second sealing part 34 includes a second body 31 and a plurality of second annular protrusions 32, the plurality of second annular protrusions 32 being arranged in parallel at intervals around the periphery of the second body 31, and the second annular protrusions 32 sealingly abutting against the lower shell 12;

[0089] Optionally, the first sealing part 33 is located between the groove wall of the relief groove and the portion of the lower shell 12 that extends into the relief groove.

[0090] In this embodiment, the first sealing part 33 consists of a first body 31 and a plurality of first annular protrusions 32. The first body 31 is a cylindrical structure, and the plurality of first annular protrusions 32 are distributed around the outer periphery of the first body 31 at equal intervals. The cross-section of the first annular protrusion 32 is semi-circular and the outer diameter is slightly larger than the inner diameter of the groove wall of the relief groove. When the first sealing part 33 is pressed into the relief groove, the first annular protrusion 32 undergoes elastic deformation and forms an interference fit with the groove wall. The second sealing part 34 includes a second body 31 and two second annular protrusions 32. The second annular protrusions 32 have a trapezoidal cross-section and are symmetrically distributed along the periphery of the second body 31. When the protruding part of the lower shell 12 is inserted into the second sealing part 34, the second annular protrusion 32 undergoes radial compression deformation and forms an annular contact surface with the outer surface of the lower shell 12. The first sealing part 33 is axially pressed between the annular step surface of the relief groove and the end face of the lower shell 12, forming a double sealing interface.

[0091] The first annular protrusion 32 and the second annular protrusion 32 are molded from elastic material and have a semi-circular cross-section. The first body 31 is integrally formed with the first annular protrusion 32 through injection molding. The second body 31 and the second annular protrusion 32 are manufactured using the same process. Furthermore, the groove wall of the relief groove can be provided with an annular groove corresponding to the first annular protrusion 32 so that the first annular protrusion 32 can be confined in the annular groove, thereby improving the sealing effect of the first sealing part 33.

[0092] Specifically, when the upper shell 11 and the lower shell 12 are assembled, the first sealing part 33 is pressed into the relief groove, and multiple first annular protrusions 32 are respectively embedded in the relief groove to form a multi-level sealing line. The end of the lower shell 12 extending into the relief groove presses against the first main body 31, causing the first annular protrusions 32 to undergo radial deformation and tightly adhere to the outer wall of the lower shell 12. When the temperature changes and the size of the shell 1 changes, the multiple first annular protrusions 32 compensate for the gap through elastic deformation. Any two adjacent first annular protrusions 32 form an independent sealing unit. The first sealing part 33 achieves axial limitation by clamping the groove wall of the relief groove with the lower shell 12, preventing the seal from axially moving under fluid pressure. When the fragrance penetrates to the sealing interface, the multi-level protrusion structure forms a labyrinthine sealing path, extending the penetration path length.

[0093] Similarly, the multiple second annular protrusions 32 of the second sealing part 34 seal against the lower shell 12 to form a multi-level sealing line, thereby ensuring the installation stability of the second sealing part 34 in the lower shell 12. When the fragrance liquid permeates to the sealing interface, the multi-level protrusion structure forms a labyrinth-like sealing path, extending the length of the permeation path.

[0094] Through the above technical solution, this application utilizes the parallel arrangement of the first annular protrusion 32 and the second annular protrusion 32 to establish a multi-level sealing interface, effectively increasing the contact area and forming an elastic deformation compensation mechanism. The interference fit between the first annular protrusion 32 and the wall of the relief groove, and the interference fit between the second annular protrusion 32 and the lower shell 12, can adapt to the difference in high-temperature expansion. Furthermore, the stepped distribution of the annular protrusions 32 enhances the tolerance to surface processing errors of the lower shell 12, which can suppress the capillary permeation phenomenon of the fragrance liquid under vibration conditions and achieve a dynamic sealing effect. Thus, the first sealing part 33 and the second sealing part 34 work together to eliminate the risk of pressure difference leakage from the single-sided sealing structure 3.

[0095] This utility model also proposes an electronic incense burner 500, such as Figure 4 As shown, the electronic incense burner 500 includes a burner body 501 and the aforementioned atomizer 100. The burner body 501 is provided with a smoke guiding channel 5011, and the atomizer 100 is disposed in the burner body 501. The atomizer 100 has a smoke guiding hole 112, which connects the smoke guiding channel 5011 and the return chamber 1a of the atomizer 100. The specific structure of the atomizer 100 is as described in the foregoing embodiments. Since this electronic incense burner 500 adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be described in detail here.

[0096] It is understood that the incense burner body 501 is a structural support component of the electronic incense burner 500, used to house and support other components of the electronic incense burner 500. Specifically, the incense burner body 501 can be made of metal, ceramic, or plastic and can fix the incense stick, power supply, and other structural components. The electronic incense burner 500 also includes an incense stick structure 502, which is a columnar structure set on the incense burner body 501 of the electronic incense burner 500, used to simulate a traditional incense stick (incense stick). The incense stick structure 502 can be fixed to the incense burner body 501 of the electronic incense burner 500, or it can be detachably set to the incense burner body 501 of the electronic incense burner 500; no limitation is made here. The incense stick structure 502 includes a column and a light-emitting element. The column can be a cylinder or a prism. The column can be made of metal, plastic or composite material and has a hollow space enclosed within it. This hollow space forms a smoke guide channel 5011, which is used to guide the smoke generated by the smoke generator inside the electronic incense burner 500 to diffuse outward. The hollow smoke guide channel 5011 formed by the column refers to a cavity with a through structure inside the column. Specifically, it can be implemented using a cylindrical or conical pipe structure. The smoke guide channel 5011 forms a smoke outlet at the end of the column away from the burner body 501 so that the smoke flows out from the smoke outlet, simulating the smoke produced when traditional incense sticks are burned.

[0097] The atomizer 100 has a vertical direction perpendicular to the horizontal plane, and part of the smoke guide channel 5011 extends in a direction perpendicular to the vertical direction, that is, it extends roughly in the direction of the horizontal plane. This allows the smoke in the return chamber 1a to slowly flow out from the side smoke guide channel 5011, preventing the smoke from flowing directly upwards, increasing the residence time of the smoke in the return chamber 1a, thereby increasing the repeated evaporation of e-liquid, and allowing some e-liquid to flow back to the wicking cotton of the atomizing component 2, thereby reducing the rapid evaporation of e-liquid and reducing e-liquid leakage and waste.

[0098] Meanwhile, the incense stick structure 502 can be mechanically fixed to the top opening of the furnace body 501, ensuring a continuous airflow path between the smoke guide channel 5011 and the internal space of the furnace body 501. Heat dissipation holes are opened on the side wall of the furnace body 501's receiving cavity, allowing external air to enter the receiving cavity through the holes and flow upwards along the smoke guide channel 5011, pushing the smoke out of the smoke outlet. The heat sink of the light-emitting element is embedded in the bottom of the mounting cavity 1b, with its end close to the heat dissipation hole of the furnace body 501. Air convection is used to conduct heat from the heat sink to the outside of the heat dissipation hole, preventing heat accumulation around the light-emitting element. After the smoke guide channel 5011 extends into the interior of the furnace body 501, its end connects with the receiving cavity, causing the smoke to form a vortex and slow down within the furnace body 501, reducing uneven smoke diffusion caused by excessively fast airflow.

[0099] Through the above technical solution, this application achieves a uniform and stable light emission effect while ensuring smooth smoke discharge. The design of the smoke guide hole 112 and the smoke guide channel 5011 having the same axis allows the smoke to be discharged through the smoke guide hole 112 along a straight path, avoiding the smoke from adhering to the surface of the light-emitting component. The physical isolation design between the LED lamp body and the smoke guide channel 5011 prevents smoke particles from blocking the light source and affecting the light intensity, and also avoids high temperature damage to electronic components. The circumferential layout of the ring light-emitting component allows the light to evenly cover the end of the incense stick, effectively simulating the ring halo effect when the traditional incense stick is burning.

[0100] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
