[0005] Sterilization / disinfection is a critical aspect of healthcare and various industries, ensuring the elimination of microorganisms. Current solutions for disinfection include manual methods, devices covering smaller coverage, devices disinfecting only air not surfaces. In particular, manual method does not provide a continuous process of disinfection and further lead to hygiene issues. Hence, hospital facilities and other sectors are not able to maintain consistently disinfected air. Further, the manual method leads to exposure to chemicals, which results to skin problems for the users. Furthermore, manual techniques result in cumbersome, time-consuming, and inconsistent disinfection. The traditional methods also leave residue that results in corrosion; thus, there is a need for improved automated, continuous, intelligent and residual-free technologies.

[0006] US11660368B2 discloses a ceiling-mounted decontamination unit to sterilize air in a room using UV-C method. The unit draws air from a room or area and subjects the air into the unit to a decontamination source, i.e., UV-C rays destroying harmful viruses, bacteria, or other pathogens, and recirculates the decontaminated air back to the same room or area. However, it fails to disclose a disinfection system that ensures disinfecting both air and surfaces using both UV-C method and ultrasonic dry misting method, and ensure disinfecting the direct exposed area as well as the indirect exposed area or hard-to-reach area. Further, it fails to achieve disinfecting a wider coverage range in a room.

[0007] JP2023049731A discloses a ceiling-mounted sterilization system which is capable sterilizing surface in a room and air using ultraviolet rays. The system includes a switching means for selectively switching between air sterilization and surface sterilization of a particular area. Thus, it fails to disclose a disinfection system that ensures disinfecting both air and surfaces using both UV-C method and ultrasonic dry misting method, and ensure disinfecting the direct exposed area as well as the indirect exposed area or hard-to-reach area. Further, it fails to achieve disinfecting a wider coverage range in a room.

[0008] Therefore, there is a requirement for an effective disinfection system. The invention aims to overcome the existing limitations by providing an automated, safe and efficient disinfection device for disinfecting both air and surface simultaneously and covering a wider range. Thus, providing thorough disinfection of surfaces and air and reaching spaces that were not achieved by existing methods.
