This invention discloses an inhalation device and application for anti-cancer and cancer-suppressing traditional Chinese medicine, belonging to the technical field of inhalation devices for traditional Chinese medicine. It includes a telescopic corrugated cylinder and an adaptive stirring assembly. The telescopic corrugated cylinder has multiple telescopic sleeves inside, and the adaptive stirring assembly includes a motor box threadedly connected to the bottom of the telescopic corrugated cylinder. This anti-cancer and cancer-suppressing traditional Chinese medicine inhalation device and application flexibly adjusts the internal space of the device according to the actual volume of the traditional Chinese medicine powder. This effectively avoids wasting space within the container and significantly reduces the overall size of the device by compressing the telescopic corrugated cylinder, improving portability and making it more suitable for daily use. The adaptive stirring assembly can adjust its structure synchronously with the telescopic corrugated cylinder's extension and retraction, always matching the internal space of the container to ensure comprehensive stirring of the powder. This allows the medicinal aroma to be evenly distributed and fully volatilized, eliminating the need for frequent manual shaking of the container. This ensures more even administration of the traditional Chinese medicine aroma, guarantees the therapeutic effect of inhalation, and significantly optimizes the user's operating experience.
