The invention discloses a material supplementing mechanism, and relates to the technical field of air disinfection machines, the material supplementing mechanism comprises a box body
assembly, the box body
assembly is internally provided with the material supplementing mechanism, the material supplementing mechanism is convenient to disassemble and assemble through a shifting ring and an embedded ring which are clamped and arranged on the material supplementing mechanism, so that a
chlorine dioxide tablet consumable bag can be conveniently installed on the embedded ring, and the material supplementing mechanism is convenient to use. When the stirring ring is stirred by the feeding
assembly for feeding, the embedded ring in the stirring ring also rotates along with the stirring ring, so that the
chlorine dioxide tablets in the consumable bag can be conveyed to the feeding position, the automatic feeding function is achieved, the requirement for storing the
chlorine dioxide tablet consumable bag is met, meanwhile, automatic feeding can be carried out when the
chlorine dioxide tablet consumable bag is used again after one-time use is finished, and the feeding efficiency is improved. Therefore, after a
chlorine dioxide tablet consumable bag is put into the device, materials can be automatically supplemented for subsequent multiple sterilization operations, the use function of the device is further expanded, and great convenience is provided for a user.
