[0052] Specifically, the hollow groove 611 provided in the metal outer shell 610 allows the fragrance of the aromatherapy core rod 612 to be emitted, and the metal outer shell 610 can be magnetically adsorbed with the magnetic ring 391 to prevent the incense stick 600 from being separated from the incense stick insertion hole.

[0053] In this embodiment: the sealing mechanism 420 includes an upper boss 421 fixedly connected to the top of the movable bracket 410, the outside of the upper boss 421 is fixedly connected to a second sealing ring, the top of the upper boss 421 is inserted and connected with a guide rod 422, the top of the outside of the guide rod 422 is fixedly connected with a T-shaped seat 423, the T-shaped seat 423 is plugged and fixed with a U-shaped seat 424 fixedly connected to the top end of the inner front box body 310, and the outside of the guide rod 422 is provided with a spring 425.

[0054] Specifically, when the fragrance control mechanism 500 lifts the movable bracket 410, the upper boss 421 of the movable bracket 410 moves upward along the guide rod 422, and at the same time compresses the spring 425. At this time, the upper boss 421 and the second sealing ring no longer seal the fragrance stick accommodating chamber 380, thereby allowing the fragrance to enter the fragrance outlet chamber 340. When the fragrance control mechanism 500 no longer lifts the movable bracket 410, the elastic action of the spring 425 causes the movable bracket 410 to move downward, and at the same time the upper boss 421 is also reset, and then cooperates with the second sealing ring to seal the fragrance outlet chamber 340.

[0055] In this embodiment: openings 331 are provided at the intersections of the two horizontal partition plates 330 and the top and bottom of the movable bracket 410. The opening 331 near the upper boss 421 is larger than the top diameter of the movable bracket 410, and the opening 331 near the lower boss 430 is adapted to the bottom diameter of the movable bracket 410.

[0056] Specifically, the opening 331 near the upper boss 421 is larger than the top diameter of the movable bracket 410, ensuring that the movable bracket 410 can be raised and lowered normally.

[0058] Specifically, the motor of the reduction motor 131 adopts a micro DC servo motor and is externally connected to a controller and a battery. The reduction motor 131 is controlled by the controller. The output shaft of the reduction motor 131 drives the driving gear 540 to rotate. The driving gear 540 cooperates with the driven gear 530 to drive the camshaft 520 to rotate. When the camshaft 520 rotates 90 degrees from the initial position, the lower boss 430 near the reduction motor 131 is lifted up. At this time, the incense stick receiving cavity 380 facing it is opened, releasing the fragrance in the incense stick receiving cavity 380. The other two incense stick receiving cavities 380 are sealed. When the camshaft 520 rotates to 180° from its initial position, the lower boss 430 in the middle is lifted up, and the incense stick accommodating chamber 380 in the middle is opened at this time, releasing the fragrance in the incense stick accommodating chamber 380, and the other two incense stick accommodating chambers 380 are sealed. When the camshaft 520 rotates to 270° from its initial position, the lower boss 430 away from the control reduction motor 131 is lifted up, and the incense stick accommodating chamber 380 opposite it is opened, releasing the fragrance in the incense stick accommodating chamber 380, and the other two incense stick accommodating chambers 380 are sealed, thereby realizing flexible control of the incense output and meeting diverse needs.
