Abstract

The utility model discloses a plasma disinfection cover with multiple air ducts, which relates to the technical field of air purification, and adopts the technical scheme that the plasma disinfection cover comprises a flow guide cover and a plasma fan, the flow guide cover comprises an upper shell and a lower shell, a cavity for accommodating the plasma fan is formed between the upper shell and the lower shell, the plasma fan is provided with a filter block, and the filter block is connected with the flow guide cover. A positioning disc is arranged in the cavity, a plurality of plasma emitters and guide plates are arranged on the positioning disc in an array mode, a first air channel is formed in the outer edge of the lower shell, a second air channel is formed in the center of the lower shell, a through hole is formed in the center of the upper shell, and the filter block is located in the center of the through hole. By arranging the filter block and a plurality of air channels, multiple protection can be formed when the device is used, airflow forms a plasma air curtain through the first air channel, airflow protection and plasma air protection are achieved, fresh air protection can be formed through the second air channel, and viruses and bacteria can be effectively isolated from the environment where a transfusion patient is located.
