The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

A vacuum machine comprising: a housing for receiving vacuumed matter and at least two removably attachable accessories; sensing means for detecting the accessories; a control circuit communicatively coupled with the sensing means; the sensing means being arranged to generate a first signal to the control circuit representative of the presence of a first accessory, a second signal representative of the presence of two accessories, the control circuit being arranged to preventing operation of the vacuum machine when the first signal is received and to allow operation of the vacuum machine when the second signal.

A vacuum cleaner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The main body is configured to form a flow-guiding path. The blower is disposed in the flow-guiding path to guide air convection. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path to detect the air pollution source and transmits a gas detection data.

An allergen reduction device may include a body, a dust cup removably coupled to the body, a plurality of agitators rotatably coupled to the body and disposed within respective agitator cavities defined in the body, a suction motor disposed within the body and configured to cause air to flow along corresponding cleaning airflow paths from the agitator cavities into the dust cup, a hot air outlet fluidly coupled to the suction motor, the suction motor being configured to urge the air through the hot air outlet along a heated exhaust airflow path, and a heater positioned within the heated exhaust airflow path between the suction motor and the hot air outlet, the heater being configured to heat the air that is urged from the hot air outlet.

The present disclosure provides a self-propelled pathogen detection device in which a place where a pathogen is highly likely to be present in a space such as an inside of a facility is allowed to be configured preferentially to be a target region of detection. The self-propelled pathogen detection device according to the present disclosure comprises a housing; a detection part for detecting a pathogen; a movement mechanism for moving the housing; a position acquirement part for acquiring position information representing a current position of the housing in a space; and a control part which determines a target region in the space on the basis of traffic line information on a person in the space, and controls the movement mechanism to move the housing in the target region on the basis of the position information. The detection part detects the pathogen in the target region.

Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.

An antibacterial cleaning machine with wet filter includes a container body inside which are disposed at least one motor group for aspirating flows of air and debris from outside; at least one first tank for collecting the debris which contains a first volume of filtering liquid which is arranged along the passage path between the inlet and outlet; at least one internal path of the flows of air and debris that includes an inlet, an outlet, conveying means that have an inlet immersed in the filtering liquid. The tank includes at least one sanitizing element made of silver and/or silver alloy which is positioned immersed in the volume of filtering liquid.

A retractable sanitizing apparatus for a vehicle including a return station, a sanitizing mechanism positionable between a first sanitizing position, a second sanitizing position, and a stowed position, the sanitizing mechanism positioned at the return station when in the stowed position, and a linkage member connecting the sanitizing mechanism to the return station and positioning the sanitizing mechanism between the first sanitizing position and the second sanitizing position, wherein the sanitizing mechanism sanitizes a surface of the vehicle as the sanitizing mechanism moves from the first sanitizing position to the second sanitizing position and across the surface of the vehicle.

Embodiments of the present invention provide systems and methods for disinfection of aircraft galleys and lavatories and other surfaces. The embodiments may use UV light sources and/or a disinfection unit powered by a fuel cell or other external power source.

An upright water filtration vacuum containing a antimicrobial particulate for anti-bacterial and anti-fungal properties. The water filtration vacuum device draws in the air, forcing it in to the water and mixing it with, e.g., nano-silver, returning clean, fresh air in to the home environment.
