Description

Technical Field

[0001] This utility model relates to the field of fragrance equipment technology, specifically to a fragrance diffuser. Background Technology

[0002] Fragrance diffusers, as electrical products that effectively enhance the ambiance and improve air quality, have been widely used in various settings in recent years. Their core function lies in atomizing liquid air fresheners such as perfumes and essential oils, then releasing these tiny droplets into the air, allowing the refreshing scent to quickly diffuse and create a more comfortable and pleasant environment for users. From homes to hotel rooms, from lobbies to corridors, and even the interiors of private cars, fragrance diffusers have become an important tool for improving the quality of life with their unique appeal.

[0003] In terms of atomization technology for fragrance devices, there are currently two main methods: ultrasonic atomization and pneumatic atomization. Among them, ultrasonic atomization has become the mainstream choice in the market due to its advantages such as simple structure, convenient operation, and ease of automatic control. This method uses the high-frequency vibration of an ultrasonic atomizing plate to rapidly disperse liquid fragrance (such as essential oils) into tiny particles, thus achieving the atomization effect. These droplets then escape from the micropores of the atomizing plate and drift into the surrounding environment.

[0004] In the practical application of ultrasonic atomization technology, some problems have also been exposed. In particular, the inverted ultrasonic atomizing fragrance devices that have emerged in recent years, while optimizing the structural design and improving atomization efficiency to some extent, still have the potential for liquid fragrance leakage. This type of device requires the bottle containing liquid fragrance to be inverted, allowing the liquid to flow under gravity and be atomized. However, in actual use, significant liquid leakage often occurs at the atomization outlet. This not only causes the outer surface of the fragrance device to become greasy and easily soiled, increasing the user's cleaning burden, but also wastes liquid fragrance, reducing the device's efficiency and economy.

[0026] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings.

[0027] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] This utility model provides a fragrance diffuser, which includes a housing 1 and a bottle 2 with an internal receiving cavity 3. An atomizing head assembly is disposed within the housing 1 and connected to the bottle 2. The atomizing head assembly includes a liquid guide rod 6, an atomizing plate 7, an atomizing seat 9, a sleeve, and a pressure relief mechanism 40. The atomizing seat 9 is connected to the bottle 2 and has a liquid accumulation space located below the receiving cavity 3. The receiving cavity 3 communicates with the liquid accumulation space through the pressure relief mechanism 40. The sleeve is located below the receiving cavity 3. In the atomizing base 9, the housing 1 is provided with an outlet 8 facing the atomizing plate 7. The sleeve is located on the side of the atomizing plate 7 away from the outlet 8. The liquid guide rod 6 is inserted into the sleeve. The first end of the liquid guide rod 6 is connected to the liquid accumulation space, and the second end of the liquid guide rod 6 is connected to the atomizing plate 7. The liquid fragrance in the liquid accumulation space flows from the first end of the liquid guide rod 6 to the second end of the liquid guide rod 6. The atomizing plate 7 atomizes the liquid fragrance at the second end of the liquid guide rod 6 and disperses it into the air from the outlet 8.

[0030] This utility model of a fragrance diffuser features an atomizing base 9 with a liquid accumulation space and a sleeve within the atomizing base 9. The first end of a liquid-guiding core rod 6 is connected to the liquid accumulation space, and the second end of the liquid-guiding core rod 6 abuts against the atomizing plate 7. By inserting the liquid-guiding core rod 6 into the sleeve, the liquid pressure on the surface of the liquid-guiding core rod 6 is reduced, thereby reducing the amount of liquid fragrance flowing to the second end of the liquid-guiding core rod 6. This prevents excessive liquid fragrance from flowing to the second end of the liquid-guiding core rod 6, making it less likely for the liquid fragrance in the liquid accumulation space to leak out of the mist outlet 8, thus reducing leakage. The receiving cavity 3 is connected to the liquid accumulation space through a pressure relief mechanism 40. After the receiving cavity 3 is depressurized through the pressure relief mechanism 40, the liquid fragrance can be transported to the liquid accumulation space, ensuring that the liquid pressure in the liquid accumulation space is reduced, further preventing the liquid fragrance in the liquid accumulation space from leaking out of the mist outlet 8.

[0031] In a preferred embodiment, the atomizing seat 9 is provided with a first partition 13 located above the sleeve. The first partition 13 separates the pressure relief chamber 406 and the lower cavity in the atomizing seat 9. The pressure relief chamber 406 and the lower cavity are connected. The sleeve and the liquid guiding core rod 6 are located in the lower cavity. The pressure relief mechanism 40 is detachably installed in the pressure relief chamber 406 for easy molding. The receiving cavity 3 is connected to the pressure relief chamber 406 through the pressure relief mechanism 40, so that the pressure of the liquid fragrance in the pressure relief chamber 406 is relatively low.

[0032] In a preferred embodiment, the pressure relief mechanism 40 is provided with a pressure relief hole 401 and a return air hole 402. The input and output ends of the return air hole 402 are respectively connected to the pressure relief chamber 406 and the receiving chamber 3, and the input and output ends of the pressure relief hole 401 are respectively connected to the receiving chamber 3 and the pressure relief chamber 406. The return air hole 402 is used to return gas to the receiving chamber 3 to ensure pressure balance. The pressure relief hole 401 discharges liquid fragrance from the receiving chamber 3 to the pressure relief chamber 406. The pressure relief hole 401 generally has a small diameter, which can reduce the pressure of the liquid fragrance in the receiving chamber 3 before discharging it into the pressure relief chamber 406, thus achieving the function of pressure relief. The pressure relief mechanism 40 is provided with a pressure relief hole 401 and a return air hole 402 so that the return air and oil discharge operations of the receiving chamber 3 are independent and do not interfere with each other.

[0033] In a preferred embodiment, the pressure relief hole 401 is higher than the return air hole 402. This means that in the usage state, the height of the pressure relief hole 401 is higher than that of the return air hole 402, and the pressure relief hole 401 is deeper into the receiving cavity 3 than the return air hole 402. This arrangement is more conducive to the return of air and the discharge of liquid fragrance from the receiving cavity 3, and the receiving cavity 3 can also more easily discharge liquid fragrance. Since liquid fragrance has a certain viscosity, it is difficult to pass through small holes, while gas passes through small holes very easily. When the cross-section of the pressure relief hole 401 is larger than the cross-section of the return air hole 402, it is ensured that gas flows through the return air hole 402, while liquid fragrance flows through the pressure relief hole 401.

[0034] In a preferred embodiment, the pressure relief mechanism 40 is provided with an oil collection groove 403, which is located at the bottom of the receiving cavity 3 and communicates with the receiving cavity 3. The pressure relief hole 401 is located at the bottom of the oil collection groove 403, and the air return hole 402 is higher than the oil collection groove 403.

[0035] In a preferred embodiment, the output end of the pressure relief hole 401 is provided with a liquid guiding groove 404 communicating with it. The cross-sectional area of ​​the liquid guiding groove 404 is larger than the cross-sectional area of ​​the pressure relief hole 401. The liquid guiding groove 404 extends along the pressure relief cavity 406, and the output end of the liquid guiding groove 404 is connected to the pressure relief cavity 406.

[0036] In a preferred embodiment, the input end of the return air hole 402 is provided with a gas collecting groove 405 communicating with it. The cross-sectional area of ​​the gas collecting groove 405 is larger than the cross-sectional area of ​​the return air hole 402. The gas collecting groove 405 extends along the pressure relief chamber 406, and the input end of the gas collecting groove 405 is connected to the pressure relief chamber 406.

[0037] In a preferred embodiment, the first partition 13 is further provided with a first through hole 18 and a second through hole 19. The first through hole 18 and the second through hole 19 are located on both sides of the second partition 14, respectively. The first through hole 18 and the second through hole 19 are respectively connected to the pressure relief chamber 406 and the second cavity 16. The positions of the first through hole 18 and the second through hole 19 correspond to the pressure relief hole 401 and the air return hole 402, respectively.

[0038] In a preferred embodiment, the pressure relief chamber 406 has an opening at the end furthest from the first partition 13. One end of the pressure relief mechanism 40 is inserted into the opening, and the pressure relief mechanism 40 is sealed to the opening. A limiting flange 407 is formed at the opening of the pressure relief mechanism 40, which protrudes outward relative to the opening. The bottom of the bottle body 2 also has a bottle mouth communicating with the receiving cavity 3. A vent hole 402 is provided at the bottle mouth and extends along the direction of the receiving cavity 3. The pressure relief hole 401 is located below the bottle mouth. The diameter of the limiting flange 407 is larger than the diameter of the opening at the upper end of the pressure relief chamber 406.

[0039] This utility model provides another embodiment of a fragrance diffuser.

[0040] The fragrance diffuser also includes an intermediate component 50, which is disposed between the second end of the liquid guide rod 6 and the atomizing plate 7. One side of the intermediate component 50 is connected to the second end of the liquid guide rod 6, and the other side is connected to the atomizing plate 7. The intermediate component 50 delivers liquid fragrance from the second end of the liquid guide rod 6 to the atomizing plate 7, and the concentration of liquid fragrance on the atomizing plate 7 is lower than that on the second end of the liquid guide rod 6. Because the concentration of liquid fragrance delivered to the atomizing plate 7 is lower, the liquid fragrance is less likely to leak out of the atomizing plate 7.

[0041] The connection area between the intermediate component 50 and the liquid-guiding core rod 6 is smaller than the connection area between the intermediate component 50 and the atomizing plate 7. The intermediate component 50 is a liquid-guiding cotton pad, and the cross-section of the liquid-guiding cotton pad is larger than the cross-section of the liquid-guiding core rod 6. Since the liquid-guiding core rod 6 outputs a fixed amount of liquid fragrance under a constant pressure, and when the liquid-guiding core rod 6 is directly connected to the atomizing plate 7, the liquid fragrance concentration at the connection point is higher, making it easier for the liquid fragrance to leak out of the mist outlet 8. The cross-section of the liquid-guiding cotton pad is larger than the cross-section of the liquid-guiding core rod 6, resulting in a lower concentration of liquid fragrance output from the liquid-guiding core rod 6 to the liquid-guiding cotton pad.

[0042] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
