  • the ultraviolet transmissive material is selected from the group consisting of quartz glass and uvio glass.
  • the described design of the claimed utility model makes it possible to ensure a high efficiency of the device, since due to the construction of the partitions and the inner wall of the housing from a material that transmits ultraviolet radiation, as well as due to the division of the internal volume of the housing into a chamber for disinfecting inhaled air and a chamber for disinfecting exhaled air, the period of time increases, during which the effect of ultraviolet radiation on the inhaled air, which enters the chamber from the environment, is carried out, which is due both to the permeability of the material used, and the length of the path that the air flow passes, circulating through the formed by means of established partitions to the channels, while simultaneously with the specified process, the process of disinfection of exhaled air is carried out.
  • the above causes a high bactericidal effectiveness of the device, safe operation of the device both for the user of the device and for the people around him, a sufficient rate of air disinfection, which prevents the user of the device from having difficulty breathing.
  • the use of widely available and inexpensive materials determines the high economic efficiency of the implementation of the proposed device for both permanent and occasional use in severe epidemiological conditions.
  • the organization of channels for the circulation of disinfected air makes it possible to ensure the optimal overall dimensions of the device, which, in turn, ensures high mobility of the device.
  • a fan is installed on the device case, which is configured to blow air into the chamber for disinfecting the inhaled air from the environment.
  • a positive pressure is created inside the device, which prevents air contaminated with infectious agents from entering the respiratory tract from outside the device.

  • the device is provided with a rechargeable UV source and fan.
  • the housing walls are made of a material that does not transmit ultraviolet radiation, which prevents undesirable effects of ultraviolet radiation on the environment of the user.
  • the ultraviolet radiation source is installed in a chamber for decontamination of inhaled air next to the separating partition, however, it is obvious that the specified source of ultraviolet radiation can be installed differently, while providing radiation exposure to the internal volume of both chambers formed in the housing.
  • the ultraviolet radiation source is an ultraviolet lamp.
  • the developed device for air disinfection does not require special maintenance, since all components are easily replaceable and are available on the market even for self-replacement of failed elements by the user (for example, an ultraviolet lamp). Such simplicity also determines the durability of the device, since the structural elements of the device have a long service life, and their replacement does not affect the quality of the device.
