Description

Technical Field

[0001] This utility model relates to the field of car air freshener technology, and in particular to a car air freshener. Background Technology

[0002] Car air fresheners, commonly used to enhance the comfort of the driving environment, primarily function by atomizing and diffusing essential oils into the vehicle's interior using an air pump. However, existing air pump designs generally suffer from excessive noise during operation. Due to the relatively enclosed and confined space inside a car, mechanical vibrations and airflow noise are easily amplified. Especially at low speeds or while idling, the continuous low-frequency humming sound generated by the air pump significantly disrupts the quietness of the cabin, affecting the auditory comfort of passengers and even interfering with the car's voice system or call quality.

[0003] Traditional air pumps, in order to meet atomization efficiency requirements, often employ high-speed motors or rigid pump body structures, but lack effective vibration reduction and noise reduction designs, resulting in prominent mechanical friction noise and airflow whistling noise during operation. Therefore, developing a car air diffuser that reduces operating noise has become a pressing technical problem for the industry. Utility Model Content

[0034] This utility model proposes a car-mounted aromatherapy diffuser.

[0035] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the car air diffuser includes an air diffuser body and an air pump body 20. The air diffuser body includes a first housing 11 and an atomizing mechanism 12 mounted on the first housing 11. The air pump body 20 is detachably mounted in a mounting slot 13 in the air diffuser body, allowing users to easily replace the air pump body 20 and thus extend the service life of the air diffuser. The shape of the mounting slot 13 is adapted to the shape of the air pump body 20, enabling quick installation of the air pump body 20.

[0036] The first housing 11 serves as the external support structure of the aroma diffuser, used to install and protect the other main components of the aroma diffuser. The atomizing mechanism 12 is disposed inside the first housing 11 and includes an atomizer 121, an essential oil bottle 122, and an air guide assembly 123 communicating with the atomizer 121. The air guide assembly 123 is used to guide the airflow delivered by the air pump body 20 to the atomizer 121, driving the atomizer 121 to atomize and diffuse the essential oil.

[0037] Furthermore, the vehicle-mounted aroma diffuser also includes an installation sleeve 30, which is fitted onto the aroma diffuser body to further improve the installation stability between the atomizing mechanism 12 and the first housing 11, thereby improving the practicality of the aroma diffuser.

[0038] The air pump body 20 includes a second housing 22 and a third housing 23, which are engaged with each other by snap-fit ​​or screws to form a closed installation space 24 for accommodating the air pump assembly 21. The second housing 22 is made of a flexible material, whose material properties can absorb and buffer vibrations generated during the operation of the air pump assembly 21, thereby effectively suppressing mechanical vibrations and low-frequency noise transmitted to the outside from the cylinder 212 component during air pump operation. The third housing 23 is a structural support component used to enhance overall rigidity and, together with the second housing 22, defines the position of the air pump assembly 21.

[0039] The flexible material can be silicone, rubber, etc., and there are no specific restrictions here.

[0040] The air pump assembly 21 is disposed in the installation space 24 formed by the second housing 22 and the third housing 23, and is connected to the atomizing mechanism 12 through the air guide assembly 123 to ensure the airflow passage is unobstructed and sealed; in addition, the second housing 22 forms a covering structure for the air pump assembly 21 through flexible covering, further improving the vibration resistance.

[0041] Through the coordinated operation of the above structures, the aroma diffuser effectively reduces the mechanical and airflow noise caused by the air pump in the vehicle environment while ensuring atomization efficiency. It is particularly suitable for vehicle interiors where a quiet environment is required, thereby improving driving comfort and user experience. It has good practicality and market promotion value.

[0042] This invention encapsulates the air pump assembly 21 within a second housing 22 made of flexible material, and then fastens it to a third housing 23 to form a closed installation structure. This ensures stable communication between the air pump and the atomizing mechanism 12 while effectively buffering vibrations generated during air pump assembly 21 operation and reducing rigid transmission paths. Simultaneously, the flexible second housing 22 absorbs and blocks air turbulence and mechanical noise generated by the air pump, reducing sound resonance and transmission within the first housing 11. This contributes to the vibration and noise reduction effect of the air pump assembly 21, thereby improving the quietness of the car air freshener and enhancing the comfort of the in-car environment.

[0043] Furthermore, such as Figures 1 to 7 As shown, the air pump assembly 21 includes a motor 211 and a cylinder 212 fixed to the motor 211. A second housing 22 covers the cylinder 212, and a third housing 23 covers the motor 211. The cylinder 212 is connected to the atomizing mechanism 12. The radial length of the cylinder 212 is greater than the radial length of the motor 211. In this embodiment, the air pump assembly 21 is driven by the motor 211 and compresses air through the cylinder 212. The cylinder 212 and the atomizing mechanism 12 are connected through the air guide assembly 123 to form a stable air path. The second housing 22 is made of flexible material and directly covers the outside of the cylinder 212 to absorb vibrations during high-frequency operation. The third housing 23 is made of rigid material and covers the outside of the motor 211, enhancing the structural strength of the first housing 11 and protecting the motor 211. The cylinder 212 has a larger diameter than the motor 211, concentrating the vibration source in the area covered by the flexible first housing 11, thereby further optimizing the vibration reduction effect. This structure balances mechanical protection and noise suppression, improving the quiet operation of the aroma diffuser.

[0044] Furthermore, such as Figures 1 to 7 As shown, the third housing 23 is made of a rigid material. In this embodiment, the third housing 23, as one of the outer shells of the air pump body 20, is made of rigid materials such as ABS plastic and PC plastic to stably support the internal motor 211 assembly and prevent the motor 211 from shifting or shaking during operation. At the same time, the rigid material has good thermal stability and structural compressive strength, which can improve the overall service life of the air pump. This design enhances the mechanical strength and assembly reliability of the air pump body 20.

[0045] Furthermore, such as Figure 4 and Figure 6As shown, both the second housing 22 and the third housing 23 have protruding fastening bosses 25 on opposite sides. The fastening bosses 25 of the second housing 22 and the third housing 23 on the same side are fixed together by screws. In this embodiment, after the second housing 22 and the third housing 23 are interlocked, they are aligned and positioned by the fastening bosses 25 located on opposite sides, and the screws pass through both for fixation, ensuring a stable connection of the first housing 11 during long-term use. This structure facilitates disassembly and maintenance while maintaining the long-term stable operation of the air pump assembly 21, avoiding vibration transmission or increased noise due to loosening of the first housing 11, and improving structural safety and durability.

[0046] Furthermore, such as Figure 2 , Figure 4 and Figure 7 As shown, the second housing 22 is provided with an air guide channel 221, one end of which is connected to the cylinder 212, and the other end is connected to the atomizing mechanism 12. In this embodiment, the air guide channel 221 is integrated into the second housing 22 as part of the airflow channel. The front end of the air guide channel 221 connects to the exhaust port of the cylinder 212, and the rear end extends to the air inlet of the atomizing mechanism 12. Through the closed air passage structure formed inside the first housing 11, the complexity of external pipeline connections is reduced. At the same time, since the second housing 22 is made of flexible material, the air passage sealing is further improved when connected to the air passage structure. Therefore, this design simplifies the air passage connection process, improves the airtightness of airflow transmission and the overall structural compactness, and helps to improve atomization efficiency and product integration.

[0047] Furthermore, such as Figures 1 to 3 As shown, the aromatherapy body also includes a cover plate 14, and the mounting groove 13 is located at the bottom of the first housing 11. The cover plate 14 is detachably installed at the bottom of the first housing 11 and closes the mounting groove 13. In this embodiment, the mounting groove 13 serves as the embedding position of the air pump body 20 and is located at the bottom of the first housing 11; the cover plate 14 is detachably installed via a snap-fit ​​or magnetic structure to close the mounting groove 13. This design allows for convenient disassembly and assembly and protection of the air pump body 20 without affecting aesthetics and overall layout, preventing external dust or impurities from entering the interior of the first housing 11, and improving the stability and cleanliness of the device.

[0048] Furthermore, such as Figures 1 to 7As shown, the second housing 22 and / or the third housing 23 have multiple abutment protrusions 26 protruding from the side facing the cover plate 14, and the abutment protrusions 26 abut against the cover plate 14. In this embodiment, the abutment protrusions 26 on the second housing 22 and / or the third housing 23 are used to form a partial surface contact with the cover plate 14, which not only serves as a limiting function but also improves the assembly strength of the air pump body 20. This structure can effectively prevent the air pump from becoming unstable in contact with the cover plate 14 or generating resonance noise due to vibration during operation, thereby enhancing the vibration reduction capability and airtightness of the structure.

[0049] Furthermore, such as Figures 1 to 3 As shown, the aromatherapy body also includes a mounting base 15, which is fixed to the bottom of the first housing 11. The mounting groove 13 is formed on the mounting base 15, and the cover plate 14 is magnetically fixed to the mounting base 15. In this embodiment, the mounting base 15 serves as a support structure for the mounting groove 13, located at the bottom of the first housing 11, and is used to embed and stably support the air pump body 20. The cover plate 14 is connected to the mounting base 15 magnetically, allowing users to disassemble and install it without tools by manually adsorbing or removing it, facilitating later maintenance and replacement of the air pump assembly 21. This structure ensures a secure connection while improving ease of use and optimizing the user experience.

[0050] In addition, an anti-slip pad 17 is fixed to the bottom of the cover plate 14, and the anti-slip pad 17 is fixed to the vehicle by applying glue or snapping.

[0051] Furthermore, such as Figures 1 to 7 As shown, the aromatherapy unit also includes a main control module, which includes a main control board 161 and a power supply socket 162 electrically connected to the main control board 161. The power supply socket 162 is provided with a power supply terminal 163 and is installed at the bottom of the mounting slot 13. The bottom of the air pump body 20 is provided with a power connection terminal 27, which movably abuts against the power supply terminal 163 of the power supply socket 162. In this embodiment, the power supply socket 162 is fixed to the bottom of the mounting slot 13 as a power input interface and is provided with a power supply terminal 163 inside. The bottom of the air pump body 20 is provided with a power connection terminal 27 opposite to the power supply terminal 163. During installation, the air pump body 20 automatically completes the electrical connection when inserted into the mounting slot 13, and disconnects when disassembled, forming a pluggable power supply structure. This solution eliminates the complex wiring or plug-in / plug-out process, improving ease of use and safety.

[0052] Furthermore, such as Figures 4 to 7As shown, the air pump body 20 also includes a movable handle 28, which is rotatably mounted on the third housing 23. In this embodiment, the movable handle 28 is mounted on the outer wall of the third housing 23 via a rotating shaft connection. When the user needs to disassemble the air pump body 20, the handle can be rotated to a vertical position for easy lifting. When not in use, it can be rotated to a hidden position that fits against the surface of the first housing 11. This structure is convenient to operate without affecting the overall aesthetics, enhancing the user-friendly design experience.

[0053] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using 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.
