[0002] The use of fragrance generators in automobiles is quite common. Fragrance generators generally include a fragrance box, an exhaust fan and a fragrance bottle. The fragrance of the fragrance bottle is blown out by the exhaust fan to create a fresh and pleasant driving environment. In order to meet the actual diversified needs, a variety of fragrance generators have appeared on the market. In the existing fragrance generating devices, in order to achieve the purpose of fragrance switching, a switching unit is generally provided for each fragrance bottle, and each fragrance bottle is individually controlled by the switching unit. For example, in the utility model patent with application number 201921137753.1 and the name of a fragrance box, three fragrance boxes are switched by three stepping motors. The advantage of this individual control method is that it can achieve mixed fragrance, but the disadvantage is also very obvious.

The device structure is cleverly designed. Moreover, when the convex column moves in the spiral section of the track groove, the upper cover assembly can be lifted and dropped relative to the fragrance box, which is convenient for replacing the fragrance bottle.

[0036] In order to facilitate the understanding of the present invention, the following description is given in conjunction with the accompanying drawings during specific use;

[0037] The circuit board receives external control signals and sends signals to control the exhaust fan and the rotation of the rotating shaft. When the convex column 31 of the rotating shaft is in the horizontal section of the track groove 211, the rotation of the rotating shaft only plays the role of switching the fragrance type. The specific situations are as follows:

[0038] 1. When the position of the containment plate 37 is aligned with the air outlet 511, the first cavity, the second cavity, and the third cavity are all closed;

[0039] 2. When the air outlet channel 34 is aligned with the air outlet 511, the air inlet channel 36 is aligned with the air inlet 513, the second cavity is in an open state, the first cavity and the third cavity are in a closed state, the exhaust fan generates negative pressure, and the air flows from the air inlet 513 to the second cavity, and flows out through the air outlet channel 34 and the air outlet 511;

[0040] 3. When the area between the containment plate 37 and the air outlet channel 34 is aligned with the air outlet 511, the first cavity (or the third cavity) is in an open state, the exhaust fan generates negative pressure, the air flows from the air inlet pipe 8 to the first cavity (or the third cavity), and the air flows out from the side hole 512 and the air outlet 511. At this time, the second cavity and the third cavity (or the first cavity) are in a closed state.

[0041] When the protrusion 31 reaches the spiral section of the track groove 211 under the control of the stepping motor, the upper cover assembly 2 and the fragrance box 5 form a relative sliding structure through the buckle and the guide groove (see Figure 1 ), so the rotation of the rotating shaft causes the boss 31 to act on the track groove 211, and accordingly, the upper cover assembly as a whole is lifted and lowered, and the fragrance bottle on the upper cover assembly is lifted and lowered accordingly, making replacement convenient.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
