[0002] Fragrance modules are devices or components that can diffuse fragrances into the surrounding environment and are widely used in automobiles, air conditioning indoor units, and home furnishings.

[0003] The circuit board in the fragrance module is one of its core components, with multiple functions and features: providing electrical connection paths for the various electronic components in the fragrance module, enabling them to communicate and work together to realize the various functions of the fragrance module; processing and transmitting various signals in the fragrance module; distributing the input power to each component that needs power and performing power management to ensure that each component can work under stable voltage and current, thereby improving the stability and reliability of the fragrance module.

[0004] Currently, the circuit board in the fragrance module is usually protected by a hard plastic sleeve. However, the fit between the hard plastic sleeve and the housing leaves a safety gap, which allows fragrance to evaporate and adhere to the circuit board, posing a risk that the circuit board may not recognize the fragrance.

[0005] Therefore, there is an urgent need to propose a sealing structure, a fragrance module, and a fragrance diffuser to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a sealing structure that isolates the fragrance factors in the fragrance cavity from the circuit board, preventing the fragrance factors from adhering to the circuit board and causing corrosion, which would prevent the circuit board from recognizing the fragrance factors.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a sealing structure that isolates the fragrance factors in the fragrance cavity from the circuit board, preventing corrosion of the circuit board caused by the fragrance factors adhering to it.

[0040] Specifically, such as Figures 1 to 4As shown, the sealing structure 1 is used to isolate the fragrance factors in the fragrance cavity 3 from the circuit board 2. The fragrance cavity 3 is an open cavity. The sealing structure 1 includes a sealing gasket 11 and a sealing soft edge 12. Along the thickness direction of the sealing gasket 11, the surface of the sealing gasket 11 can abut against the surface of the circuit board 2, and the side surface of the sealing gasket 11 abuts against the inner sidewall of the opening of the open cavity. Along the circumference of the sealing gasket 11, the sealing soft edge 12 is disposed on the side surface of the sealing gasket 11, and the sealing soft edge 12 is press-fitted against the outer sidewall of the top of the open cavity. The side surface of the sealing gasket 11 abuts against the sidewall of the opening of the open cavity to achieve the effect of sealing the open cavity. The press-fitting of the sealing soft edge 12 with the outer sidewall of the open cavity further improves the sealing performance of the entire sealing structure 1, so that the fragrance factors in the fragrance cavity 3 are isolated from the circuit board 2 by the sealing structure 1, thereby preventing the fragrance factors from adhering to the circuit board 2, corroding the circuit board 2, and causing the circuit board 2 to be unable to recognize the fragrance factors.

[0041] Furthermore, both the sealing gasket 11 and the sealing soft edge 12 are made of soft rubber. During the connection process between the sealing gasket 11 and the sealing soft edge 12 and the sidewall of the opening, they are more easily deformed by compression, thereby better preventing fragrance factors from adhering to the circuit board 2. In other embodiments, the sealing gasket 11 is made of soft rubber, or the sealing soft edge 12 is made of soft rubber. In this embodiment, both the sealing gasket 11 and the sealing soft edge 12 are made of silicone rubber; in other embodiments, both the sealing gasket 11 and the sealing soft edge 12 are made of butyl rubber or polyurethane adhesive.

[0042] Optionally, the sealing gasket 11 has a through hole 13, and the circuit board 2 has a spring pin 21 inserted therein. The spring pin 21 can pass through the through hole 13 to protect the spring pin 21 and prevent the spring pin 21 from being misaligned during the sealing process, thereby affecting the circuit connection on the circuit board 2.

[0043] Furthermore, the number of through holes 13 is at least two. At least two through holes 13 allow spring pins 21 at different positions to pass through them. The spring pins 21 passing through different through holes 13 can be used for various identification methods such as NFC identification, SIM card identification, and resistance identification, thereby improving the applicability of the sealing structure 1. In this embodiment, the number of through holes 13 is five. In other embodiments, the number of through holes 13 can be two, four, or six, etc.

[0044] Optionally, a sealing ring 14 is also provided on the side surface of the sealing gasket 11. The sealing ring 14 is coaxial with the sealing gasket 11, and the sealing soft edge 12 is fixedly connected to the sealing gasket 11 through the sealing ring 14, thereby extending the sealing soft edge 12 and further improving the sealing effect of the sealing structure 1.

[0045] Furthermore, along the axial direction of the sealing ring 14, the sealing soft edge 12 and the side surface of the sealing gasket 11 are set at an angle, making the sealing soft edge 12 fit more tightly with the outer wall of the top of the opening, thereby further preventing fragrance factors from flowing out of the opening of the opening and causing corrosion of the circuit board 2.

[0046] Furthermore, the thickness of the sealing ring 14 is less than the thickness of the sealing gasket 11, and the top outer wall of the opening is connected to the sealing ring 14, increasing the contact area with the top outer wall of the opening and further improving the sealing effect of the sealing structure 1.

[0047] Furthermore, along the thickness direction of the sealing gasket 11, the bottom of the sealing ring 14 is flush with the bottom of the sealing gasket 11. This stepped structure increases the contact area between the entire sealing structure 1 and the circuit board 2, thereby improving the protection effect on the circuit board 2.

[0048] This embodiment also provides a fragrance module that isolates the fragrance factors in the fragrance cavity from the circuit board, preventing the circuit board from being unable to recognize other fragrance factors due to the fragrance factors adhering to the circuit board and causing corrosion.

[0049] Specifically, such as Figures 4 to 7 As shown, a fragrance module includes a circuit board 2 and the aforementioned sealing structure 1. A spring pin 21 is inserted into the circuit board 2, passing through the opening of the oral cavity to form an electrical connection with other components. The side surface of the sealing gasket 11 abuts against the side wall of the oral cavity opening, achieving a sealing effect. The sealing soft edge 12 is interference-fitted with the outer wall of the oral cavity, further improving the sealing performance of the entire sealing structure 1. This isolates the fragrance factors in the fragrance cavity 3 from the circuit board 2, preventing the fragrance factors from adhering to the circuit board 2 and causing corrosion, which would prevent the spring pin 21 from recognizing other fragrance factors and reduce the fragrance module's monitoring and control functions for fragrance factors.

[0050] Optionally, the fragrance module also includes a fragrance bottle, which is placed inside the opening to store fragrance liquid and work with other components to release fragrance factors. When the fragrance bottle is installed in place, the spring pin 21 contacts the conductive ring or electrode on the identification chip to form an electrical connection, enabling the circuit board 2 to read the information of the fragrance bottle, such as the fragrance type and remaining amount, thereby realizing the control and monitoring of the fragrance function.

[0051] Furthermore, the number of fragrance bottles and sealing structures 1 is at least two, and they correspond one-to-one. In this embodiment, the number of fragrance bottles and sealing structures 1 is three. In other embodiments, the number of fragrance bottles and sealing structures 1 is two, four, or five, etc.

[0052] This embodiment provides another fragrance diffuser that isolates the fragrance factors inside the fragrance chamber from the circuit board, preventing the fragrance factors from adhering to the circuit board and causing corrosion, thus reducing the working stability of the fragrance diffuser.

[0053] Specifically, such as Figures 5 to 7 As shown, a fragrance diffuser includes a housing 4 and the aforementioned fragrance module, with the fragrance module housed within the housing 4. The side surface of the sealing gasket 11 abuts against the side wall of the opening of the fragrance cavity 3, achieving a sealing effect on the opening. The sealing soft edge 12 is interference-fitted with the outer wall of the opening, further improving the sealing performance of the entire sealing structure 1. This isolates the fragrance factors in the fragrance cavity 3 from the circuit board 2, preventing the fragrance factors from adhering to the circuit board 2 and causing corrosion. This would prevent the spring needle 21 from recognizing other fragrance factors, reducing the fragrance module's monitoring and control functions for fragrance factors, and consequently reducing the stability of the fragrance diffuser's operation.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
