Background

The existing vehicle interior adopts a large number of plastic or leather accessories, so that the smell in the vehicle is poor, and in addition, the vehicle interior space is narrow and small, the air circulation effect is poor, so that a driver and passengers often feel uncomfortable when driving. Especially, peculiar smell is more obvious on a new car, and the driving experience is seriously influenced. As a result, vehicle mounted perfume ornaments or hangers have become one of the more common accessories in vehicles. The most common vehicle-mounted perfume device products on the market are mainly classified into two types: one type is a fragrance device which naturally volatilizes perfume or solid perfume, such as various vehicle-mounted perfume ornaments or suspension parts. Because the fragrance of the incense is volatilized naturally, the incense device can still volatilize the fragrance continuously after a driver and passengers stop and close the door, so that the fragrance is excessively strong and choked when the driver and the passengers drive the door next time, the user experience is very poor, and the perfume or the solid perfume is wasted. The other type is an aromatherapy machine which adopts the power-on heating to promote the volatilization, the fragrance is diffused by the electric heating or atomizing principle, the fragrance can be quickly enhanced in the vehicle, and the fragrance is not volatilized any more after the power is off. The product also promotes the volatilization of the perfume or the spice by uniformly heating through electrifying, and if the driving time is too long, the fragrance is easy to be too strong, and the perfume is also quickly used up, thereby causing unnecessary waste. The applicant finds that the best use mode of the vehicle-mounted aromatherapy device is that the perfume is released to volatilize each time in a quantitative mode, and then the perfume is released again after the fragrance in the vehicle is faded or disappears according to the needs of a user, so that the aim of randomly and quantitatively controlling the fragrance in the vehicle is achieved according to the needs, the fragrance in the vehicle is controlled to be balanced, and the perfume is saved and used.
