Abstract: Disclosed is an air purifier. The air purifier includes an outer housing assembly, an outer side filter element and an inner side filter element. The outer housing assembly defines a mounting cavity, and the outer housing assembly is provided with air inlet holes communicated with the mounting cavity. The outer side filter element is disposed in the mounting cavity. The inner side filter element includes a high efficiency particulate air (HEPA) layer and an activated carbon layer, and the inner side filter element is disposed on a radial inner side of the outer side filter element. The outer side filter element can be separately detached.

Abstract: The present application proposes a multi-media three-dimensional additive printer, comprising: a column, a top plate, a turntable and a printing platform; the column is a vertically installed circular cylinder, and the top plate is horizontally mounted on the column; a plurality of printing nozzles are mounted on the lower surface of the top plate, and each of the printing nozzles slides in a direction in which the radius of the column is extended; the turntable is rotatably mounted on the column and disposed coaxially with the column, and the turntable is relatively stationary with the column in the vertical direction; the printing platform is horizontally mounted on the turntable and rotates synchronously with the turntable.

Abstract: The present application discloses a method and a system for multi-object universal intelligent printing, the method includes: collecting a real-time image of an object to be printed, and displaying the real-time image of the object to be printed to the user in real time; moving a print head to a designated position according to a mobile nozzle command input after the user browses the real-time image; obtaining a print pattern input by the user; printing the print pattern onto the object to be printed through the print head.

Abstract: The present invention belongs to the field of medical materials. A nano-oxide/kaolin composite hemostatic antibacterial material includes an iron oxide/kaolin composite carrier, and zinc oxide supported on the surface of the composite carrier. The present invention further provides the preparation and application of the composite hemostatic antibacterial material. Furthermore, the present invention provides a hemostatic healing-promoting dressing including the composite hemostatic antibacterial material disclosed by the present invention. The present invention surprisingly finds from research that the zinc oxide and iron oxide/kaolin composite carrier have a synergistic effect, and further cooperated with a special loading morphology, the synergistic effect of the two is unexpectedly enhanced, the hemostatic property and antibacterial property of the material are effectively improved, and moreover, the rate of wound healing is further improved.

Abstract: The present invention discloses an iron oxide/nanokaolin composite hemostatic agent and a preparation method thereof. The composite hemostatic agent is composed of nanokaolin and iron oxide, where the nanokaolin is used as a carrier, and the iron oxide is loaded on a surface of a nanokaolin flake. The composite hemostatic agent is obtained by a precipitation method. The composite hemostatic agent has the advantages of good hemostatic effect, rapid wound healing, no obvious cytotoxicity, no hemolysis, high biocompatibility, and the like.
