The touch button PCB 28, the indicator light PCB 31, the driving member 16 and the fan 18 are all electrically connected with the main PCB 34, so that the driving member 16 and the fan 18 can be started to run through the touch button. When a certain accommodating space is in the flow-through state, the air outlet 19 can output the fragrance of the fragrance 2 located in the accommodating space. Correspondingly, the light-emitting lamp plate 25 corresponding to the accommodating space is lit, indicating that the fragrance 2 is being used.

[0053] Working principle: when it is needed to purify the surrounding environment, the driving member 16 and the fan 18 are started by touching the touch button. The driving end drives the switching shaft 3 to rotate, so that one of the accommodating spaces is switched from the closed state to the flow-through state. Under the suction force generated by the operation of the fan 18, external air enters the mounting space through the third air inlet 21, and enters the accommodating space through the air inlet channel corresponding to the accommodating space. The fragrance of the fragrance 2 located in the accommodating space is carried into the air outlet box 17 through the air outlet channel, and finally the fragrance is output to the outside from the air outlet 19. At the same time, the light-emitting lamp plate 25 corresponding to the accommodating space is lit;

[0054] When the user wants to switch to other fragrances 2, the driving member 16 is worked by touching the touch button, the driving end drives the switching shaft 3 to rotate, so that the accommodating space is switched from the flow-through state to the closed state, and another accommodating space is switched from the closed state to the flow-through state. In this way, different fragrances 2 can be switched, different fragrances can be output, and the light-emitting lamp plate 25 corresponding to the used fragrance 2 is lit, indicating that the fragrance 2 is being used;

[0055] When it is needed to close the device, the driving member 16 drives the switching shaft 3 to rotate by touching the touch button, so that the planes where the through parts of the three connecting segments of the switching shaft 3 are located are all perpendicular to the corresponding accommodating spaces. In this way, the three accommodating spaces are all in the closed state. At this time, the light-emitting lamp plate 25 is extinguished, and the driving member 16 and the fan 18 stop running.

[0056] The above description is only the preferred embodiment of the present application and the explanation of the technical principles. It should be understood by those skilled in the art that the scope of the protection of the present application is not limited to the technical solutions formed by the specific combinations of the above technical features. It should also cover other technical solutions formed by the combinations of the above technical features or their equivalent features without departing from the concept of the present application.
