  • Publication number: 20230158191
    Abstract: A fogging system may include a fogging device including a fluid reservoir, a first fluid atomizer coupled to the fluid reservoir, and a processor configured to operate the first fluid atomizer to atomize fluid from the fluid reservoir in a first operating mode. The system may further include at least one fogging accessory removably attachable to the fogging device and comprising circuitry configured to identify a fogging accessory device type associated with the at least one fogging accessory, and a second fluid atomizer configured to atomize fluid from the fluid reservoir when the at least one fogging accessory is attached to the fogging device. The processor may be configured to detect the fogging accessory device type from the circuitry and switch to a second operating mode responsive to the detection, with the second operating mode being different than the first operating mode.

  • Patent number: 11291740
    Abstract: A system for disinfecting an enclosed chamber may include a housing, an inlet and an outlet carried by the housing to be connected in a closed airflow path with the enclosed chamber. A dehumidification chamber, a blower, and an evaporation chamber may be carried by the housing and connected in the airflow path between the inlet and outlet. An atomizing nozzle may be positioned within the evaporation chamber and connected to a disinfectant fluid reservoir and an air compressor and configured to atomize disinfectant within the evaporation chamber. An airflow valve may be connected in the airflow path, and a controller may be configured to, during a treatment phase, operate the compressor to introduce atomized disinfectant into the airflow path, and during an evacuation phase, operate the airflow valve to divert the airflow path through the desiccation chamber to remove atomized disinfectant from the airflow path.

  • Publication number: 20210252179
    Abstract: A system for treating an enclosed area having an access door with an atomized fluid may include a fogging device including a housing and an atomizing generator carried by the housing including an atomizing nozzle in fluid communication with a fluid reservoir, and a compressor coupled to the atomizing nozzle. The fogging device may further include a processor, and the system may further include a controller configured to selectively actuate an electronic door lock actuator to lock and unlock the access door. The processor may be configured to communicate with the controller to initiate an automated treatment cycle during which the compressor dispenses atomized fluid into the enclosed area via the atomizing nozzle while the access door is locked, and to not dispense atomized fluid into the enclosed area while the access door is unlocked.

  • Patent number: 10092668
    Abstract: A fogging device for disinfecting an enclosed area with an atomized disinfectant fluid may include a housing, and an atomizing disinfectant generator carried by the housing and including a disinfectant fluid reservoir, a compressor coupled to the disinfectant fluid reservoir, and an atomizing nozzle in fluid communication with the disinfectant fluid reservoir. A first processor may be carried by the housing and coupled to the compressor and configured to perform a treatment cycle during which the compressor is operated to dispense atomized disinfectant fluid from the disinfectant fluid reservoir into the enclosed area via the atomizing nozzle. The treatment cycle may include a saturation phase wherein the compressor operates to dispense atomized disinfectant fluid continuously to bring the enclosed area to a target saturation level, and a pulse phase wherein the compressor operates to intermittently dispense atomized disinfectant fluid to maintain the enclosed area at the target saturation level.
