Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted fragrance products, in particular to a vehicle-mounted fragrance generating device. Background Art

[0002] There are basically two types of existing car perfumes (or aromatherapy): the first type does not use electricity, and adds cotton cores, rattan, corks, etc. to allow the fragrance (or aroma) to evaporate naturally, or blow it out through the car vents; the second type uses external power supply, heats and evaporates, or uses a micro fan to blow out the fragrance. However, the two existing car perfumes have the following defects:

[0003] (1) The first type of fragrance is not controlled. Even in the hot summer, the fragrance evaporates quickly and easily overflows from the bottle, causing the fragrance in the car to be too strong or even pungent. The overflowed perfume liquid will also cause certain corrosion to the car interior. The overflow of perfume will also cause certain waste and increase the frequency of refilling perfume, which is not a good experience.

[0004] (2) The second type requires power supply conditions, and generally requires an external power cord (except for high-end models that have their own power cord). The cost of use is high, and the connection of the power cord also affects the appearance of the car interior. The fragrance also needs to be replenished frequently, which is not good for use.

[0005] In view of the above-mentioned inadequate problems, this solution proposes a vehicle fragrance generating device. Summary of the invention

[0006] The invention aims to solve the problems of the two existing car perfumes: the first type has uncontrolled fragrance emission, which is easy to overflow from the bottle, resulting in waste and increasing the frequency of perfume replenishment; the second type requires an external power supply, which is costly to use, and the power cord connection affects the beauty of the car interior, resulting in frequent perfume replenishment and poor use.

[0041] The assembly of the device is carried out according to the drawings of this specification, and the various components are tightly matched to effectively prevent loosening and splashing of liquid perfume. The working process of the device is briefly described as follows: when driving, the vibration of the car drives the liquid perfume in the box body 1 to shake left and right. When the liquid perfume shakes to the left, the air pressing the upper part of the left box body 1 pushes the air outlet valve 6 at the left end to bring out the fragrance, and the air inlet valve 4 at the right end introduces the outside air into the box body 1. At this time, the fragrance channel is: second air inlet cavity 81→box body 1→liquid perfume→first air outlet cavity 22. When the liquid perfume shakes to the right, the air pressing the upper part of the right box body 1 pushes the air outlet valve 6 at the right end to bring out the fragrance, and the air inlet valve 4 at the left end introduces the outside air into the box body 1. At this time, the fragrance channel is: first air inlet cavity 21→box body 1→liquid perfume→second air outlet cavity 82. When the car stops, there is no vibration, so the liquid perfume will not shake, the air inlet valve 4 and the air outlet valve 6 are in a closed state, and no fragrance is discharged. In addition, when the adjustment knob 10 is in the closed position, the air exchange between the inside and outside of the box body 1 is prevented. When the car is driving, the liquid perfume in the box body 1 shakes very little and no fragrance is discharged. It should be noted that the device adopts a two-fragrance channel alternating continuous fragrance discharge mode, which is better than other products with a one-way interval fragrance discharge mode.

[0042] In summary, the technical solution of the present invention has the following beneficial effects:

[0043] The present invention solves the deficiencies of the two existing car perfumes. The vibration of driving drives the liquid perfume to shake left and right to form a pressure difference between the inside and outside of the box to start emitting fragrance. The fragrance emission is automatically turned off when the car stops. The air pressure inside and outside the box can be automatically balanced when driving. The perfume will not overflow in hot or cold weather. When not driving, the volatilization of the perfume can be effectively controlled, making the perfume more durable and greatly extending the use time. The device uses the liquid perfume to shake in the U-shaped box to generate different air pressures inside and outside the box, and uses the air inlet valve and the air outlet valve to discharge the fragrance. It has a simple structure, low cost, does not require electricity, and is energy-saving and environmentally friendly. The device uses an adjustment button to steplessly adjust the concentration of the fragrance emission, and can be designed to be ultra-thin, suitable for being placed on the co-pilot center console.
