[0003] However, the structure of the existing car aromatherapy using fragrance diffusers is complicated. After the internal fragrance diffuser has no fragrance, it is necessary to frequently replace the fragrance diffuser or add perfume to the fragrance diffuser. Moreover, the entire car aromatherapy must be disassembled to replace the fragrance diffuser or add perfume. The whole process is complicated and cumbersome. The method of using a liquid-absorbing cotton core to absorb perfume for fragrance diffusion is prone to leakage and overflow, and the overall appearance is also relatively simple.

[0004] In view of the above problems, there is a structure that uses a perfume container and a breathable film to achieve fragrance dispersion. For example, as shown in the previously disclosed patent "CN201080017262.9", a sealed aluminum foil is integrated inside the perfume container, and a piercing element for piercing the aluminum foil is set between the breathable film and the aluminum foil to achieve the outflow of perfume and fragrance dispersion. In this method, the aluminum foil, the piercing element and the breathable film are integrated in the perfume container, resulting in a complex overall structure and a difficult production and processing process. In addition, the piercing element directly contacts the aluminum foil, and the aluminum foil is prone to the risk of being pierced by mistake during the production and assembly process. As shown in the previously disclosed patent "CN202280069115.9", a movable body that can be pressed inward and moved is set on the inner side of the back cover to achieve the purpose of piercing the aluminum foil. However, in this method, a movable body is added on the inner side of the back cover, and a corresponding connection structure is also set between the movable body and the back cover, resulting in a complex overall structure and a difficult production and processing process.
