A kind of perfume generator
Technical field
The utility model belongs to automobile air freshening apparatus field, and in particular to a kind of perfume generator.
Background technology
Currently, vehicle-mounted perfume mostly after based on dress, be mostly installed on air-conditioner air outlet or console, by opening manually
It opens or always open state, volatilizees giving forth fragrance by nature.It does not simply fail to adjust fragrance diffusion velocity, more duty uses
Person's visual space destroys interior overall beautiful.Major defect is:
1. perfume is filled after and is not included in full-vehicle control system, belongs to independent use;
2. it is beautiful to destroy interior arrangement for duty user's visual space;
3. not having sealing structure, it is easy to spill in perfume when vehicle jolts;
4. do not support automatic opening/closing, it is cumbersome;
5. relying primarily on the natural volatilization of perfume, the diffusion velocity of fragrance can not be adjusted;
6. can not automatic identification perfume surplus, rely primarily on user visual inspection.
