Description

Technical Field

[0001] This application relates to the field of carrier technology, specifically to a fragrance diffuser and a carrier having the same. Background Technology

[0002] With the development of the automotive industry, improving the comfort of the in-car environment has become a key focus for consumers. In-car fragrance devices effectively improve air quality and enhance the user's driving experience by diffusing fragrance into the passenger cabin.

[0003] Currently, most common in-car fragrance technologies are integrated with vehicle air conditioning systems, which have low water requirements. However, for independently designed, detachable fragrance diffusers, existing technologies typically require users to periodically add water to maintain their fragrance function. This reliance on liquid replenishment limits the portability and ease of use of such diffusers, thus impacting the user experience. Utility Model Content

[0004] In view of this, this application provides a fragrance diffuser and a carrier thereon to solve the problem that existing fragrance diffusers require regular water replenishment, which affects the user experience.

[0005] In a first aspect, this application provides a fragrance diffuser, comprising a housing, an atomizing device, a fragrance container, and a condensing device. The atomizing device is disposed within the housing and includes an atomizing chamber, an air outlet communicating with the atomizing chamber, and a liquid inlet. The air outlet communicates with the external space of the housing. The fragrance container has a fragrance outlet communicating with the atomizing chamber. The condensing device is disposed within the housing and includes a condensing section. The housing has a vent corresponding to the condensing section. The condensing section is used to generate condensate and discharges the condensate into the atomizing chamber through the liquid inlet.

[0006] Beneficial effects: The fragrance diffuser is equipped with a condensation device that actively captures moisture from the air to form condensate. The condensate is then introduced into the atomizing chamber and atomized by the atomizing device. This condensation device enables the fragrance diffuser to have a self-sufficient water supply, replacing the traditional manual water replenishment method. This eliminates the need for regular water replenishment of the fragrance diffuser, thereby improving its portability and ease of operation, and ultimately enhancing the user experience.

[0007] In one optional embodiment, the condensation device includes a thermoelectric cooler with a cold end and a hot end. The cold end forms the condensation section. A first flow channel and a second flow channel are provided inside the housing. The air inlet of the first flow channel is connected to the vent hole, and the condensation section is disposed within the first flow channel. The housing is provided with an exhaust hole, and the air outlet of the second flow channel is connected to the exhaust hole of the housing. The hot end is disposed within the second flow channel.

[0008] Beneficial effects: Utilizing a thermoelectric cooler to generate condensate results in a simple overall structure, small footprint, and low operating cost for the condensation device. Furthermore, the cold and hot ends of the thermoelectric cooler are located in the first and second flow channels respectively, and the spatial isolation between the cold and hot ends prevents mutual interference, improving the condensation efficiency of the cold end while ensuring the heat dissipation efficiency of the hot end.

[0009] In one optional embodiment, the outlet end of the first flow channel is connected to an air passage, the air passage is connected to the second flow channel, and the air passage and the vent are respectively disposed on both sides of the condensation section; wherein, a fan is disposed in the first flow channel; and / or, a fan is disposed in the second flow channel.

[0010] Beneficial effects: By connecting the first and second flow channels with an air passage, the airflow passes through the cold end of the thermoelectric cooler before passing through the hot end, avoiding the mixing of hot and cold airflows that could interfere with the condensation efficiency at the cold end. Furthermore, the air passage and vents are respectively located on both sides of the condenser section, forcing the airflow along the surface of the condenser section and improving condensate generation efficiency. A fan is installed in the first and / or second flow channels to increase the airflow velocity within them. This accelerates heat exchange between the air and the condenser section, further improving condensate generation efficiency, and also enhances the heat dissipation efficiency of the hot end of the thermoelectric cooler, preventing overheating.

[0011] In one optional embodiment, a first partition and a second partition are spaced apart inside the housing. A first flow channel is formed between the surface of the first partition and the second partition facing the first partition and the inner wall of the housing. A second flow channel is formed between the surface of the second partition facing away from the first partition and the inner wall of the housing. The semiconductor cooling chip is disposed on the second partition. An overflow hole is provided on the side of the second partition away from the vent, and the overflow hole forms the air passage.

[0012] Beneficial effects: By incorporating a first and second partition within the housing, the cold end region of the thermoelectric cooler is isolated from other spaces within the housing. This ensures a directional flow path for air passing through the cold end of the thermoelectric cooler, thereby improving cooling water generation efficiency. A second flow channel is formed on the other side of the second partition, allowing heat generated at the hot end of the thermoelectric cooler to be discharged through an independent channel, thus preventing interference between hot and cold airflows. Simultaneously, the second partition also provides installation space for the thermoelectric cooler, facilitating its installation.

[0013] In one alternative embodiment, the distance between the first baffle and the second baffle gradually decreases along the direction from the vent to the flow hole in the first flow channel; and / or, the first baffle includes a first plate segment and a second plate segment at an angle to each other along the direction from the vent to the flow hole in the first flow channel, the angle between the first plate segment and the second baffle being greater than the angle between the second plate segment and the second baffle.

[0014] Beneficial effects: In the first flow channel, the distance between the first and second baffles gradually decreases along the airflow direction, which accelerates the airflow velocity through the condenser section and enhances the contact strength between the air and the cold end of the semiconductor cooling chip, thereby improving the efficiency of condensate generation. The first plate segment and the second baffle form a large angle, which facilitates guiding the airflow quickly into the condensation area on the vent side. The second plate segment and the second baffle form a smaller angle, which can maintain a more stable airflow direction near the flow hole side, thereby reducing pressure loss and lowering the overall operating energy consumption of the fragrance diffuser.

[0015] In one alternative embodiment, a fan is provided inside the exhaust port.

[0016] Beneficial effects: The integrated fan inside the exhaust vent eliminates the need for a separate fan installation location inside the casing, resulting in a compact overall structure for the fragrance diffuser, shortening the airflow path, and reducing airflow energy loss. Furthermore, the fan actively extracts hot airflow from the end of the second flow channel, creating negative pressure in the second flow channel. This forces air from the first flow channel into the second flow channel through the air passage, achieving air circulation between the outside of the casing, the first flow channel, and the second flow channel. This ensures continuous condensation at the cold end of the semiconductor cooling chip.

[0017] In one optional embodiment, the condensation device further includes a water collection tank and at least one water guide pipe. The water collection tank is disposed on the lower side of the condensation section; the at least one water guide pipe connects the water collection tank and the liquid inlet.

[0018] Beneficial effects: The water collection tank is located on the lower side of the condenser section, naturally collecting the condensate formed on the surface of the condenser section by gravity, thus preventing the condensate from dripping disorderly inside the shell and improving the condensate collection efficiency. The water guide pipe serves as a liquid transmission channel, facilitating the delivery of the collected condensate into the atomizing chamber through the liquid inlet.

[0019] In one optional embodiment, a smoke ring generator is disposed within the housing, the smoke ring generator comprising a gas channel and a piston assembly. One end of the gas channel is connected to the atomizing chamber; the piston assembly is disposed within the gas channel, the piston end of the piston assembly being adapted to reciprocate along the axial direction of the gas channel; and / or, an ambient light assembly is disposed at the outlet of the atomizing chamber.

[0020] Beneficial effects: When the piston end of the piston assembly reciprocates axially within the gas channel, it generates pulsed airflow disturbances, which in turn promotes the formation of a vortex-like smoke ring effect in the atomizing chamber. The ambient light assembly is positioned at the air outlet of the atomizing chamber. Through the interaction of different colored lights with the atomizing gas, it causes the atomized gas to change color, thereby enhancing the visibility of the atomized gas and increasing visual interest.

[0021] In one optional embodiment, the atomizing device includes an atomizing cylinder and an atomizer. The atomizing chamber is formed inside the atomizing cylinder; the atomizer is disposed at the bottom of the atomizing cylinder.

[0022] Beneficial effects: By combining the atomizing cylinder and the atomizer, the atomization process is ensured to be continuous while preventing the overflow of un-atomized liquid, thereby improving the atomization efficiency and stability of condensate and realizing the efficient utilization of condensate.

[0023] Secondly, this application provides a carrier including any of the above-described fragrance diffusers.

[0024] Beneficial effects: By installing the above-mentioned fragrance diffuser inside the vehicle, it is not necessary to replenish the fragrance diffuser with water regularly, which improves the portability and ease of operation of the fragrance diffuser. Furthermore, by combining atomized water vapor with fragrance, it provides a dual sensory experience for the vehicle's interior environment, which combines both smell and sight.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] The following is combinedFigures 1 to 9 This describes an embodiment of the present application.

[0047] According to an embodiment of this application, in a first aspect, a fragrance diffuser is provided, comprising a housing 1, an atomizing device 2, a fragrance container 3, and a condensing device 4. The atomizing device 2 is disposed within the housing 1 and includes an atomizing chamber 201, an air outlet 202 communicating with the atomizing chamber 201, and a liquid inlet 203. The air outlet 202 communicates with the external space of the housing 1. The fragrance container 3 includes a fragrance outlet 301 communicating with the atomizing chamber 201. The condensing device 4 is disposed within the housing 1 and includes a condensing section 401. The housing 1 has a vent corresponding to the condensing section 401. The condensing section 401 is used to generate condensate and discharges the condensate into the atomizing chamber 201 through the liquid inlet 203.

[0048] In this embodiment, as Figure 1 , Figure 2 As shown, the housing 1 can be hemispherical, square, or other decorative shapes. The housing 1 has an internal space for accommodating the atomizing device 2 and the condensing device 4. The housing 1 has a vent 101, an exhaust vent 102, and a mist exhaust port 103. The atomizing device 2 converts the liquid in the atomizing chamber 201 into aerosol through physical or chemical means. The atomizing device 2 includes the atomizing chamber 201 and a connected air outlet 202 and liquid inlet 203. The air outlet 202 corresponds to and communicates with the mist exhaust port 103 on the housing 1, allowing the aerosol in the atomizing chamber 201 to be discharged from the housing 1 sequentially through the air outlet 202 and the mist exhaust port 103.

[0049] The aromatherapy container 3 serves as a container for holding aromatherapy liquid and is provided with an aromatherapy outlet 301. During daily use, the liquid aromatherapy in the aromatherapy container 3 continuously evaporates to generate gaseous molecules. The gaseous molecules enter the atomization chamber 201 through the aromatherapy outlet 301, mix with the mist in the atomization chamber 201, and are then discharged from the shell 1 through the air outlet 202.

[0050] The condenser 4 actively captures moisture in the air through the condenser section 401 to form condensate, and introduces the condensate into the atomizing chamber 201 for atomization by the atomizing device 2. The condenser 4 enables the fragrance diffuser to have a self-sufficient water supply.

[0051] In this embodiment, as Figure 1 , Figure 2As shown, ambient air outside the housing 1 enters the area surrounding the condenser section 401 of the condenser device 4 through the vent 101 on the housing 1. Water vapor in the air condenses into condensate on the surface of the condenser section 401. The condensate is collected and guided into the atomizing chamber 201. The atomizing device 2 atomizes the condensate in the atomizing chamber 201 into a mist. The liquid fragrance in the fragrance container 3 continues to evaporate and is injected into the atomizing chamber 201 through the fragrance outlet 301, so that the fragrance molecules and the mist are mixed to form a fragrant mist, which is finally discharged into the external environment outside the housing 1.

[0052] With this configuration, a condenser 4 is installed inside the fragrance diffuser. The condenser 4 actively captures moisture from the air through the condenser section 401 to form condensate, which is then introduced into the atomizing chamber 201 and atomized by the atomizing device 2. The condenser 4 enables the fragrance diffuser to have a self-sufficient water supply, replacing the traditional manual water replenishment method. This eliminates the need for regular water replenishment of the fragrance diffuser, thereby improving its portability and ease of operation, and ultimately enhancing the user experience.

[0053] Optionally, the aroma diffuser container 3 can be disposed inside or outside the housing 1. When the aroma diffuser container 3 is disposed inside the housing 1, the housing 1 covers the aroma diffuser container 3 to prevent leakage, thus making the overall structure of the aroma diffuser compact and aesthetically pleasing. When the aroma diffuser container 3 is disposed outside the housing 1, the aroma outlet 301 of the aroma diffuser container 3 passes through the housing 1 and extends into the atomizing chamber 201, ensuring communication between the aroma diffuser container 3 and the atomizing chamber 201, while facilitating the replacement of the aroma diffuser container 3 or the replenishment of liquid aroma diffuser in the aroma diffuser container 3.

[0054] Optionally, the aforementioned fragrance diffuser is applied to a vehicle, such as a car, construction machinery, or other ground-based mobile equipment, or a low-altitude aircraft. Furthermore, the housing 1 can be fixed to the interior space of the vehicle using methods such as adhesive bonding, snap-fitting, magnetic attraction, or bolting.

[0055] Of course, in addition to being placed inside the vehicle, the aforementioned fragrance diffuser can also be placed in other environments as a device to release fragrance.

[0056] In one embodiment, the condensing device 4 includes a semiconductor refrigeration chip, which includes a cold end and a hot end 402. The cold end forms a condensation section 401. A first flow channel 5 and a second flow channel 6 are provided inside the housing 1. The air inlet end of the first flow channel 5 is connected to the vent 101, and the condensation section 401 is disposed inside the first flow channel 5. The housing 1 is provided with an exhaust port 102, and the air outlet end of the second flow channel 6 is connected to the exhaust port 102 of the housing 1. The hot end 402 is disposed inside the second flow channel 6.

[0057] In this embodiment, as Figure 2 , Figure 3 , Figure 4As shown, a thermoelectric cooler is a semiconductor device that uses the Peltier effect to achieve temperature control. Specifically, it can be implemented using a thermoelectric module made of bismuth telluride-based material. The thermoelectric cooler includes a low-temperature cold end and a relatively high-temperature hot end. The low-temperature cold end can form a low-temperature surface to promote water vapor condensation. In addition to the thermoelectric cooler, the condensation device 4 also includes a power supply component to supply power to the thermoelectric cooler, enabling it to operate normally.

[0058] The air inlet of the first flow channel 5 is connected to the vent 101 on the housing 1, thereby guiding external air to exchange heat with the condenser 401. The air outlet of the second flow channel 6 is connected to the exhaust port 102 on the housing 1, thereby discharging the heat generated by the hot end 402 into the second flow channel 6. By separating the first flow channel 5 and the second flow channel 6, the hot air in the second flow channel 6 is prevented from affecting the condensation effect of the condenser 401 in the first flow channel 5. Furthermore, the vent 101 and the exhaust port 102 are relatively far apart on the housing 1, which effectively prevents the hot air discharged from the exhaust port 102 from re-entering the first flow channel 5 through the vent 101, thereby preventing energy loss caused by the mixing of hot and cold air.

[0059] When outside air enters the first flow channel 5 through the vent 101, it flows over the cold end surface of the semiconductor cooling chip, i.e., the surface of the condenser 401. Water vapor in the air condenses upon contact with the cold surface, forming condensate. The condensate flows downward along the cold end surface under gravity and is collected and sent into the atomization chamber 201. At the same time, the heat generated by the hot end 402 of the semiconductor cooling chip is introduced into the second flow channel 6, and the hot air is directionally discharged outside the housing 1 through the exhaust port 102.

[0060] This configuration, by setting up independent first flow channel 5 and second flow channel 6, physically separates the cold-end condensation process from the hot-end 402 heat dissipation process, eliminating thermal interference from hot air on the condensation surface and ensuring that the condensation section 401 remains within its optimal operating temperature range. This, in turn, ensures continuous condensate production, meeting the atomization requirements of the atomizing device 2. Furthermore, the second flow channel 6, serving as an independent heat dissipation channel for the hot end 402, guarantees the heat dissipation efficiency of the hot end 402 and extends the lifespan of the thermoelectric cooler. In addition, utilizing the thermoelectric cooler to form condensate results in a simple overall structure, small footprint, and low operating cost for the condensation device 4.

[0061] Of course, in addition to the semiconductor cooling chip mentioned above, the condensing device 4 can also use other condensing structures, with simplicity of structure and low operating cost being preferred.

[0062] In one embodiment, the outlet end of the first flow channel 5 is connected to the air passage 7, the air passage 7 is connected to the second flow channel 6, and the air passage 7 and the vent 101 are respectively disposed on both sides of the condenser 401; wherein, a fan 8 is disposed in the first flow channel 5; and / or, a fan 8 is disposed in the second flow channel 6.

[0063] In this embodiment, as Figure 3 , Figure 4 , Figure 5 As shown, the air passage 7 connects the first flow channel 5 and the second flow channel 6, and the condenser 401 is disposed between the vent 101 and the air passage 7. When air enters the first flow channel 5 through the vent 101, moisture condenses on the surface of the condenser 401 to form condensate. The airflow carrying the remaining cooling capacity enters the second flow channel 6 through the air passage 7, exchanges heat with the hot end 402, and is then discharged. In this way, by using the air passage 7 to connect the first flow channel 5 and the second flow channel 6, the airflow passes through the cold end of the semiconductor cooling chip and then through the hot end 402. This avoids the mixing of hot and cold airflows interfering with the condensation efficiency of the cold end, and the residual cooling at the cold end can also be used to dissipate heat from the hot end 402, improving energy utilization efficiency. Furthermore, the vent 101 and the air passage 7 are respectively disposed on both sides of the condenser 401, forcing the airflow to flow along the surface of the condenser 401, thereby improving the condensate generation efficiency.

[0064] In this embodiment, the airflow velocity in the first flow channel 5 and the second flow channel 6 is increased by the fan 8. On the one hand, this accelerates the heat exchange between the air and the condenser 401, further improving the efficiency of condensate generation. On the other hand, it improves the heat dissipation efficiency of the hot end 402 of the semiconductor cooling chip, preventing the semiconductor cooling chip from overheating.

[0065] A fan 8 can be installed in either the first flow channel 5 or the second flow channel 6 to increase the airflow velocity. Alternatively, a dual-fan configuration can be used, with fans 8 installed in both the first flow channel 5 and the second flow channel 6, to further increase the airflow velocity.

[0066] In one embodiment, a first partition 9 and a second partition 10 are spaced apart inside the housing 1. A first flow channel 5 is formed between the surface of the first partition 9 and the inner wall of the housing 1, and a second flow channel 6 is formed between the surface of the second partition 10 away from the first partition 9 and the inner wall of the housing 1. A semiconductor cooling chip is disposed on the second partition 10. An overflow hole is provided on the side of the second partition 10 away from the vent 101, and the overflow hole forms an air passage 7.

[0067] In this embodiment, as Figure 7As shown, the second partition 10 has a first side 1001 and a second side 1002 disposed opposite to each other. The first side 1001 of the second partition 10 is close to the first partition 9. An air passage 7 is formed on the second partition 10. The first partition 9, the first side 1001 of the second partition 10, and the inner wall of the housing 1 enclose a first flow channel 5. The second side 1002 of the second partition 10 and the inner wall of the housing 1 enclose a second flow channel 6. The first partition 9 and the second partition 10 are disposed at intervals. By controlling the relative positions of the first partition 9 and the second partition 10, the cross-sectional dimensions of the first flow channel 5 and the second flow channel 6 can be controlled, thereby forming independent airflow channels through physical separation and avoiding interference from the mixing of hot and cold air.

[0068] A flow passage is provided on the second partition 10. One or more flow passages can be provided, forming an air passage 7 that connects the first flow channel 5 and the second flow channel 6, allowing the condensed air in the first flow channel 5 to naturally transition into the second flow channel 6. In this way, the first partition 9 and the second partition 10 work together to isolate the cold end area of ​​the thermoelectric cooler from other spaces inside the housing 1, ensuring that air forms a directional flow path when flowing through the cold end of the thermoelectric cooler, thereby improving the cooling water generation efficiency. A second flow channel 6 is formed on the other side of the second partition 10, dissipating the heat generated by the hot end 402 of the thermoelectric cooler through an independent channel, thus avoiding mutual interference between hot and cold airflows. At the same time, the second partition 10 also provides installation space for the thermoelectric cooler, facilitating its installation.

[0069] In one embodiment, the distance between the first baffle 9 and the second baffle 10 in the first flow channel 5 gradually decreases along the direction from the vent 101 to the flow hole; and / or, in the first flow channel 5 along the direction from the vent 101 to the flow hole, the first baffle 9 includes a first plate segment and a second plate segment that are at an angle to each other, and the angle between the first plate segment and the second baffle 10 is greater than the angle between the second plate segment and the second baffle 10.

[0070] In this embodiment, as Figure 3 , Figure 4As shown, in the first flow channel 5, the distance between the first baffle 9 and the second baffle 10 gradually decreases along the airflow direction, forming a tapered flow channel structure. Specifically, the first baffle 9 and the second baffle 10 can be inclined baffles, accelerating airflow through the contraction of the flow channel cross-section. When air enters the first flow channel 5 through the vent 101, the tapered flow channel structure gradually increases the airflow velocity, enhancing the forced convection heat transfer effect between the air and the condenser section 401. As the flow velocity increases, the contact strength between the air and the cold end of the semiconductor cooling chip is enhanced, the residence time of the air on the surface of the condenser section 401 is shortened, but the heat transfer per unit volume is increased, effectively improving the moisture condensation efficiency. Furthermore, the tapered arrangement of the first flow channel 5 can also reduce airflow separation, lower flow resistance, and avoid energy loss caused by turbulence.

[0071] In this embodiment, as Figure 4 As shown, the first partition 9 includes a first section 901 and a second section 902. The first section 901 forms a large angle α1 with the second partition 10, creating an expanding inlet on the air intake side of the first flow channel 5, reducing initial airflow resistance and facilitating the rapid flow of air into the condensation area via the vent 101. The second section 902 forms a small angle α2 with the second partition 10, ensuring a smooth transition in the latter half of the first flow channel 5. This maintains relatively stable airflow guidance near the air passage 7, preventing vortex losses caused by sudden changes in flow velocity, thereby reducing pressure loss and lowering the overall energy consumption of the fragrance diffuser.

[0072] In one embodiment, a fan 8 is disposed within the exhaust port 102. Besides the aforementioned arrangement of the fan 8 within the first flow channel 5 and / or the second flow channel 6, other fan configurations may also be used. Figure 2 As shown, the fan 8 can also be integrated and fixedly installed inside the exhaust port 102. Integrating the fan 8 inside the exhaust port 102 avoids the need for a separate installation location for the fan 8 inside the housing 1, thus making the overall structure of the fragrance diffuser compact, shortening the airflow path, and reducing airflow energy loss. Furthermore, the fan 8 actively extracts and exhausts the hot airflow at the end of the second flow channel 6. Under the action of the fan 8, the second flow channel 6 generates negative pressure, causing air from the first flow channel 5 to enter the second flow channel 6 through the air passage 7. This achieves air circulation outside the housing 1, through the first flow channel 5, and through the second flow channel 6, ensuring continuous condensation at the cold end of the semiconductor cooling chip.

[0073] Of course, a fan 8 can be installed in the first flow channel 5 and / or the second flow channel 6 and / or the exhaust port 102 to meet different usage requirements.

[0074] In one embodiment, the condensation device 4 further includes a water collection tank 403 and at least one water guide pipe 404. The water collection tank 403 is disposed on the lower side of the condensation section 401; the at least one water guide pipe 404 connects the water collection tank 403 and the liquid inlet 203.

[0075] In this embodiment, as Figure 6 , Figure 7 As shown, the water collection tank 403, serving as a container for collecting condensate, is positioned directly below the condenser section 401. The water collection tank 403 can be fixed to one or more of the bottom wall of the housing 1, the first partition 9, and the second partition 10, depending on actual needs. Specifically, the water collection tank 403 can adopt a groove structure with an inclined bottom surface. The sidewalls of this groove structure have a certain height to prevent condensate overflow. A water guide pipe 404 connects the water collection tank 403 and the atomizing chamber 201, guiding the condensate from the water collection tank 403 into the atomizing chamber 201. Multiple water guide pipes 404 can be provided, with the inlet end of the water guide pipe 404 inclined and the outlet end connected to the atomizing chamber 201 higher than the inlet end connected to the atomizing chamber 201. The water guide pipe 404 can be a silicone flexible tube with an inner diameter of 1-2 mm, allowing condensate to be transported by gravity, avoiding the energy consumption and noise associated with traditional pumping methods.

[0076] When condensation forms on the cold end surface of the semiconductor cooling chip, the droplets slide down the surface of the condensation section 401 under the action of gravity into the water collection tank 403. The inclined structure of the water collection tank 403 causes the condensation to converge at the inlet of the water guide pipe 404. Through the surface tension of the inner wall of the water guide pipe 404 and the action of the liquid's own weight, a continuous and stable liquid flow is formed and transported to the atomizing chamber 201.

[0077] In one embodiment, a smoke ring generator 11 is provided inside the housing 1. The smoke ring generator 11 includes a gas channel 111 and a piston assembly 112. One end of the gas channel 111 is connected to the atomizing chamber 201; the piston assembly 112 is disposed inside the gas channel 111, and the piston end of the piston assembly 112 is adapted to reciprocate along the axial direction of the gas channel 111; and / or, an ambient light assembly 12 is provided at the air outlet 202 of the atomizing chamber 201.

[0078] In this embodiment, as Figure 8 As shown, the piston assembly 112 includes a piston 1121 and a drive mechanism 1122. The piston 1121 is slidably engaged with the gas channel 111, and the drive mechanism 1122 is fixed within the gas channel 111 and located on the side of the piston 1121 away from the atomizing chamber 201. The drive mechanism 1122 can be implemented using electromagnetic drive, motor drive, or telescopic cylinder drive, and the airflow pulse intensity is adjusted by controlling the stroke frequency of the piston 1121. The ambient light assembly 12, as a lighting device, can generate multi-color light sources, for example, by using an RGB LED module with a light guide plate, and color switching is achieved through a control circuit.

[0079] When the aroma from the fragrance container 3 flows into the atomizing chamber 201, the atomizing device 2 activates to produce atomized gas, and the piston assembly 112 moves axially at a set frequency. During the retraction phase of the piston 1121, a negative pressure is created to accelerate the gas flow, drawing air from outside the housing 1 into the atomizing chamber 201. During the pushing phase, the piston 1121 generates a positive pulse airflow, and through alternating pressure changes, the mixed gas forms a vortex ring structure at the air outlet 202, producing a visible smoke ring effect. Simultaneously, the light from the ambient light assembly 12 illuminates the surface of the atomized gas, and through the Mie scattering effect, the smoke rings display different colors, thereby enhancing the visibility of the atomized gas and increasing visual interest.

[0080] In one embodiment, the atomizing device 2 includes an atomizing cylinder 204 and an atomizer 205. An atomizing chamber 201 is formed inside the atomizing cylinder 204; the atomizer 205 is disposed at the bottom of the atomizing cylinder 204.

[0081] In this embodiment, as Figure 8 As shown, the atomizing cylinder 204 is preferably vertically disposed within the housing 1 along its height direction. The atomizing cylinder 204 can be a cylindrical metal cylinder with a smooth inner wall surface and a hydrophobic coating to reduce liquid residue. An atomizing chamber 201 is formed inside the atomizing cylinder 204. The inner wall of the atomizing cylinder 204 restricts the spatial range of the atomizing chamber 201, allowing the condensate in the atomizing chamber 201 to naturally collect at the bottom area of ​​the atomizing cylinder 204 under the action of gravity.

[0082] The atomizer 205 can be embedded in the bottom plane of the atomizing cylinder 204. The working surface of the atomizer 205 directly contacts the accumulated condensate. When the atomizer 205 is activated, the liquid forms a uniform liquid film on the surface of the atomizer 205, which is converted into micron-sized droplets through high-frequency vibration or heating. The vertical extension characteristic of the atomizing chamber 201 causes the atomized airflow to rise axially and be directionally discharged through the top air outlet 202 and the mist exhaust port 103 on the housing 1.

[0083] Optionally, the atomizer 205 can be implemented using a piezoelectric ceramic atomizing plate or an ultrasonic transducer. The working surface of the atomizer 205 is set to correspond to the bottom plane of the atomizing cylinder 204 to ensure that the atomizer 205 is always covered by the liquid surface and to avoid atomization interruption due to uneven liquid distribution.

[0084] Furthermore, such as Figure 9As shown, the aroma diffuser also includes a controller 13. The controller 13 is electrically connected to the drive mechanism 1122 of the piston assembly 112, and is adapted to operate the drive mechanism 1122 to control the movement speed of the piston 1121 of the piston assembly 112, thereby controlling the frequency of smoke ring generation. The controller 13 is also electrically connected to the ambient light assembly 12, and is adapted to control the color and brightness of the ambient light assembly 12. The controller 13 is electrically connected to the atomizer 205, and is adapted to control the atomization level of the atomizer 205.

[0085] Thus, by providing a control panel on the surface of housing 1, the frequency and color of the smoke rings can be adjusted to meet different usage needs. Furthermore, to ensure the normal operation of the aforementioned electronic components, housing 1 is equipped with a battery and an external power outlet to supply power to these components. The specific usage of these electronic components follows conventional technology and will not be elaborated upon here.

[0086] Secondly, this application provides a carrier including any of the above-mentioned fragrance diffusers.

[0087] Alternatively, the vehicle may be, for example, a car, construction machinery or other ground-based mobile equipment, or it may be a low-altitude aircraft.

[0088] In this embodiment, by installing the aforementioned fragrance diffuser inside the vehicle, it is not necessary to regularly rehydrate the fragrance diffuser, thus improving its portability and ease of operation. Furthermore, the combination of atomized water vapor and fragrance provides a dual sensory experience for the vehicle's interior environment, offering both olfactory and visual benefits.

[0089] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
