Description

[Technical Field]

[0001] The present invention relates to the technical field of in-vehicle aroma diffusers, and more particularly to an in-vehicle aroma diffuser. [Background technology]

[0002] In-car aroma diffusers are commonly used devices for improving ride comfort. Their core function is to atomize and diffuse aromatic essential oils into the interior of the vehicle using an air pump. However, conventional air pump structures often suffer from excessive noise during operation. Because the interior space of a vehicle is relatively enclosed and narrow, mechanical vibrations and airflow noise tend to be significantly amplified. Particularly when driving at low speeds or idling, the persistent low-frequency whine generated by the air pump significantly disrupts the quietness of the vehicle interior, impacting the hearing comfort of the driver and passengers and ultimately affecting the quality of the in-car voice system or conversations.

[0003] To meet the atomization efficiency requirements, conventional air pumps usually adopt high-speed motors or rigid pump body structures, but lack effective vibration damping and noise cancellation designs, which cause prominent mechanical friction noise and wind noise during operation. Therefore, developing an in-car aroma diffuser that reduces operating noise has become a technical problem that the industry is urgently waiting to solve.

[0020] This invention proposes an in-car aroma diffuser.

[0021] 1 to 7, the in-car aroma diffuser includes an aroma body and an air pump body 20. The aroma body includes a first case 11 and an atomizing mechanism 12 mounted on the first case 11. The air pump body 20 is removably mounted in a mounting groove 13 drilled in the aroma body, allowing users to easily replace the air pump body 20 and further extending the service life of the aroma diffuser. The mounting groove 13 is shaped to fit the shape of the air pump body 20, allowing for quick installation of the air pump body 20.

[0022] The first case 11 is used as an external load structure of the aroma diffuser to mount and protect other main body components of the aroma diffuser. The atomization mechanism 12 is installed inside the first case 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 transported by the air pump body 20 to the atomizer 121 and drive the atomizer 121 to atomize and diffuse the essential oil.

[0023] Furthermore, this in-car aroma diffuser further includes a mounting sleeve 30, which is fitted onto the aroma body, thereby further improving the mounting stability between the atomization mechanism 12 and the first case 11 and further improving the practicality of the aroma diffuser.

[0024] The air pump body 20 includes a second case 22 and a third case 23, which are fitted together by snap fitting or bolts to form a sealed mounting space 24 for housing the air pump assembly 21. The second case 22 is made of a flexible material, and its material properties allow it to absorb and cushion vibrations generated by the air pump assembly 21 during operation, thereby effectively suppressing mechanical vibrations and low-frequency noise transmitted to the outside by the air cylinder 212 during operation of the air pump. The third case 23 is a structural support member that reinforces the overall rigidity and, together with the second case 22, defines the position of the air pump assembly 21.

[0025] Here, the flexible material may be silica gel, rubber, etc., and is not limited to these.

[0026] The air pump assembly 21 is installed in an installation space 24 consisting of a second case 22 and a third case 23, and is connected to the atomization mechanism 12 via an air guide assembly 123, ensuring the airflow passage and sealing performance. Furthermore, the second case 22 forms a covering structure for the air pump assembly 21 using a flexible covering, further improving vibration-proofing performance.

[0027] Through the cooperation of the above structures, the aroma diffuser can effectively reduce the mechanical noise and airflow noise caused by the operation of the air pump in the vehicle environment while ensuring atomization efficiency, and is particularly suitable for vehicle interiors where a quiet environment is required, thereby improving riding comfort and user experience, and has good practicality and market penetration value.

[0028] The technical solution of the present invention packages the air pump assembly 21 within the second case 22 made of a flexible material, and engages with the third case 23 to form a sealed mounting structure, thereby ensuring stable communication between the air pump and the atomization mechanism 12 while effectively cushioning vibrations generated during operation of the air pump assembly 21 and reducing rigid conduction paths. At the same time, the flexible second case 22 has a certain absorption and shielding effect on the air interference sound and mechanical noise generated by the air pump, reducing resonance in the first case 11 and sound transmission to the outside, contributing to the shock absorption and noise cancellation effects of the air pump assembly 21, thereby improving the noise reduction performance of the car aroma diffuser and improving the comfort of the car interior environment.

[0029] 1 to 7, the air pump assembly 21 includes a motor 211 and an air cylinder 212 fixedly mounted on the motor 211, the second case 22 is installed to cover the air cylinder 212, and the third case 23 is installed to cover the motor 211, the air cylinder 212 is in communication with the atomization mechanism 12, and the radial length of the air 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 and delivers air via the air cylinder 212, which is in communication with the atomization mechanism 12 via an air guide assembly 123 to form a stable air passage. The second case 22 is made of a flexible material and directly covers the outside of the air cylinder 212 to absorb vibrations during the high-frequency operation of the air cylinder 212, while the third case 23 is made of a rigid material and covers the outside of the motor 211 to reinforce the structural strength of the first case 11 and provide protection for the motor 211. The air cylinder 212 has a larger diameter than the motor 211, concentrating the vibration source in the area covered by the flexible first case 11, thereby further optimizing the shock absorption effect. This structure combines mechanical protection and noise suppression, improving the quiet operation of the aroma diffuser.

[0030] 1 to 7, the third case 23 is made of a rigid material. In this embodiment, the third case 23 is one of the housings of the air pump body 20 and is made of a rigid material such as ABS plastic, PC plastic, etc., to stably support the internal motor 211 assembly and prevent displacement or vibration caused by the operation of the motor 211. At the same time, the rigid material provides good thermal stability and structural pressure resistance, thereby extending the service life of the entire air pump. This design enhances the mechanical strength and assembly reliability of the air pump body 20.

[0031] 4 and 6, a fastening boss 25 is protruded from each of the opposing sides of the second case 22 and the third case 23, and the fastening boss 25 of the second case 22 on the same side is fixed to the fastening boss 25 of the third case 23 via a screw. In this embodiment, after the second case 22 and the third case 23 are engaged with each other, the fastening bosses 25 located on the opposing sides are used to position them, and screws are passed through both to fasten them, ensuring a stable connection with the first case 11 over long periods of use. This structure not only facilitates installation and removal and maintenance, but also ensures long-term stable operation of the air pump assembly 21, prevents vibration transmission or increased noise due to loosening of the first case 11, and improves structural safety and durability.

[0032] 2, 4, and 7, the second case 22 is provided with an air guide passage 221, one end of which communicates with the air cylinder 212 and the other end of which communicates with the atomization mechanism 12. In this embodiment, the air guide passage 221 is integrated into the second case 22 as part of the air flow passage. The front end of the air guide passage 221 is aligned with the exhaust port of the air cylinder 212 and the rear end of the air guide passage 221 extends to the intake port of the atomization mechanism 12. The sealed air passage structure formed inside the first case 11 reduces the complexity of external pipe connections, and the second case 22 is made of a flexible material, further improving the sealing of the air passage when connected to the air passage structure. This design simplifies the air passage connection process, improves the airtightness of the air transport and the compactness of the overall structure, and contributes to improving atomization efficiency and the degree of product integration.

[0033] 1 to 3, the aroma body further includes a cover plate 14, the mounting groove 13 being located at the bottom of the first case 11, and the cover plate 14 being removably attached to the bottom of the first case 11 and sealing the mounting groove 13. In this embodiment, the mounting groove 13 is opened at the bottom of the first case 11 as the mounting position for the air pump body 20, and the cover plate 14 is removably attached via a snap fit or magnetic attraction structure to seal the mounting groove 13. This design allows for easy installation and removal of the air pump body 20 and protects it, while not affecting the aesthetics or overall layout, and prevents external dust or foreign objects from entering the first case 11, improving the stability and cleanliness of the device.

[0034] 1 to 7, a plurality of abutment protrusions 26 are provided on the second case 22 and / or the third case 23 on 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 provided on the second case 22 and / or the third case 23 are used to form localized surface contact with the cover plate 14, serving as a stopper and improving the assembly strength of the air pump body 20. This structure can effectively prevent the air pump from vibrating during operation and causing unstable contact with the cover plate 14 or generating resonance noise, thereby enhancing the vibration-damping ability and airtightness of the structure.

[0035] 1 to 3, the aroma body further includes a mounting seat 15, which is fixedly mounted on the bottom of the first case 11. The mounting groove 13 is drilled on the mounting seat 15, and the cover plate 14 is fixed to the mounting seat 15 by magnetic attraction. In this embodiment, the mounting seat 15 is installed on the bottom of the first case 11 as a support structure for the mounting groove 13 and is used to insert and stably load the air pump body 20. The cover plate 14 is connected to the mounting seat 15 by magnetic attraction, allowing the user to attach and detach it by hand without tools, facilitating subsequent maintenance and replacement of the air pump assembly 21. This structure ensures a solid connection while also improving convenience and optimizing the user experience.

[0036] A bath mat 17 is fixedly attached to the bottom of the cover plate 14, and the bath mat 17 is fixed to the vehicle by applying adhesive or by a fastening method.

The electrical connection terminal 27 opposite to the power supply terminal 163 is installed at the bottom of the air pump body 20. When installed, the air pump body 20 automatically completes the electrical connection when inserted into the mounting groove 13 and cuts it off when removed, forming a pluggable power supply structure. This solution eliminates the need for complicated wiring or plugging and unplugging processes, improving convenience and safety of use.

[0038] 4 to 7, the air pump body 20 further includes a movable handle 28, which is rotatably mounted on the third case 23.
