Description

Technical Field

[0001] The utility model belongs to the technical field of aromatherapy, and in particular relates to a vehicle-mounted air outlet aromatherapy. Background Art

[0002] As people's living standards improve, the number of families owning private cars continues to increase. In order to improve the air environment inside private cars, people usually place solid air fresheners, spray perfumes or place aromatherapy essential oils in the car to make the car fragrant, eliminate the fatigue of the driver and passengers, liven up the atmosphere in the car and increase driving pleasure.

[0003] However, the structure of the existing car aromatherapy using fragrance diffusers is complicated. After the internal fragrance diffuser has no fragrance, it is necessary to frequently replace the fragrance diffuser or add perfume to the fragrance diffuser. Moreover, the entire car aromatherapy must be disassembled to replace the fragrance diffuser or add perfume. The whole process is complicated and cumbersome. The method of using a liquid-absorbing cotton core to absorb perfume for fragrance diffusion is prone to leakage and overflow, and the overall appearance is also relatively simple.

[0004] There is a structure that uses a perfume bag and a breathable film to cooperate with each other to achieve fragrance dispersion. As shown in the previously disclosed patent "CN201080017262.9", a sealed aluminum foil is integrated inside the perfume bag, and a piercing element for piercing the aluminum foil is provided between the breathable film and the aluminum foil to achieve the outflow of the perfume and the dispersion of the fragrance. In this manner, the aluminum foil, the piercing element and the breathable film are integrated in the perfume bag, resulting in a complex overall structure and a difficult production and processing process. In addition, the piercing element directly abuts against the aluminum foil, and there is a risk of the aluminum foil being accidentally pierced during the production and assembly process.

[0005] In addition, for air vent type aromatherapy, the aromatherapy is mainly clamped in the air vent for use, but the clip and the aromatherapy body are usually fixed with screws or rivets, which makes assembly and disassembly inconvenient. Moreover, after long-term use, the screw fixing method may become loose, causing the clip and the aromatherapy body to loosen. Utility Model Content
