  • Patent number: 12128742
    Abstract: The present invention relates to an air purifier comprising a housing with an air inlet and an air outlet. A filter module, a power supply module, a drive module and a processing module are sequentially arranged in the housing along an airflow direction. The drive module gives a drive force to the air, so that the air enters into the housing from the air inlet, then in turn flows through the filter module, the power supply module, the drive and processing modules. The filter module filters out large particle pollutants in the air such as dust. The power supply module is used to supply power to the drive module and the processing module. The processing module is used to remove bacteria and organic pollutants in the air. Therefore, the degree of air purification can be improved, so that the air is purified to the ideal state as much as possible.

  • Publication number: 20240216460
    Abstract: A Salvia plebia and Scutellariae radix compound acne cream, a preparation method therefor and an application thereof. Stearic acid, vaseline, lanolin, glycerol monostearate and cetyl alcohol are heated and mixed to obtain an oil phase; glycerol and triethanolamine are fusion-mixed to obtain a water phase; and the water phase, the oil phase, a Scutellariae radix extract and a Salvia plebia extract are mixed, water is added to specified volume and the mixture is mixed uniformly to obtain the Salvia plebia and Scutellariae radix compound acne cream. The problems of large toxic and side effects, long treatment period and drug resistance of pathogenic bacteria of existing acne-treating drugs are solved. The Chinese medicine-based cream is prepared from a novel external preparation cream, has strong skin adhesion and good biocompatibility, and can effectively facilitate drugs to penetrate stratum corneum, reach an action site and exert a curative effect.
