[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0036] Example

[0037] like Figures 1 to 12As shown, the vehicle-mounted aromatherapy device shown in this embodiment comprises a shell 1 having a cavity 10, a perfume container 2 disposed in the shell 1 and used to accommodate a fragrance-emitting substance, and a clip 3 detachably disposed on the outer side of the rear end of the shell, so that the vehicle-mounted aromatherapy device can be clamped on the air vent of the automobile air conditioner by using the clip 3, and the air blown out of the air vent of the automobile air conditioner is used to improve the fragrance diffusion effect; the rear end of the shell 1 is provided with a plurality of air inlet holes 11 connected with the cavity 10, and the air inlet holes 11 can be used as air inlet and air outlet at the same time; the rear end of the perfume container 2 is an opening, and a rupturable sealing sheet 21 made of a liquid-impermeable material for sealing is provided at the opening, and a volatile film 22 located on the outer side of the rupturable sealing sheet 21 is also provided at the rear end of the perfume container 2, and the rupturable sealing sheet 21 and the volatile film 22 are arranged on the outer side of the rupturable sealing sheet 21. The volatile membranes 22 are arranged closely adjacent to each other, and the thickness of the rupturable sealing sheet 21 is smaller than that of the volatile membrane 22, so that the rupturable sealing sheet 21 is configured to rupture with a smaller elongation than the volatile membrane 22 when an external force is applied to the volatile membrane 22 from the outside in the thickness direction; the inner side protrusion of the rear end of the shell 1 is provided with a thorn 12 arranged toward the volatile membrane 22, the thorn 12 is arranged adjacent to the volatile membrane 22, and one end of the thorn 12 close to the volatile membrane 22 is non-sharp, and the front end of the shell 1 is provided with a button 4 for pressing and pushing the perfume container 2 to squeeze the thorn 12 backward, so that the rupturable sealing sheet 21 is deformed and ruptured during the squeezing process, so that the perfume in the perfume container 2 flows outward through the rupture to the volatile membrane 22 to volatilize and disperse the fragrance;

[0038] In the above, a perfume container containing a scented fragrance substance is used as the main body of the fragrance diffuser, which avoids the problem of continuously adding perfume or replacing the fragrance diffuser when the fragrance diffuser absorbs perfume and diffuses the fragrance, that is, the process of disassembling the shell is reduced, and the overall structure is simple; in addition, the rupturable sealing sheet arranged at the open end of the perfume container can be used to seal the perfume container before it is unpacked for use, thereby avoiding the problem of waste caused by the volatilization of the perfume in the perfume container. When in use, the perfume container is pressed backward by pressing a button, so that the volatilization film and the rupturable sealing sheet move backward and are squeezed by the spurs, and the end of the spurs is set to be not sharp. The rupture seal will not directly puncture the volatile film and the rupture seal sheet, but will only cause the volatile film and the rupture seal sheet to deform after being squeezed. During the extrusion and deformation process, the rupture seal sheet will rupture at the squeezed position, while the volatile film will not rupture, so that the perfume in the perfume container will flow out from the ruptured position of the rupture seal sheet and be absorbed by the volatile film, and then slowly evaporate and disperse the fragrance, so that the car-mounted air vent aromatherapy has a long fragrance retention time and will not waste perfume.
