An odor detection device includes an odor sensor for measuring an ambient odor, a fan that exhausts air around the odor sensor, and a substrate for controlling the fan and the odor sensor. Electric power supplied to the odor sensor, the fan, and the substrate is supplied from outside of the odor detection device, the substrate includes a connection unit capable of transmitting and receiving data to and from an external device that is a device separate from the odor detection device, and the fan is installed downstream of an airflow generated by the fan itself with respect to the odor sensor.

Proposed is an air conditioning assembly of a vehicle seat. The air conditioning assembly includes a housing provided in a vehicle seat, in which air flows in an internal space of the housing and the air is discharged to a seating surface of the seat, and an air cleaner provided in the internal space of the housing and configured to selectively sterilize or deodorize the air flowing in the internal space of the housing by rotating according to an air conditioning mode.

The Desktop Air Purifier with Double-layer Glass Tube Ultraviolet Disinfection Lamp (The desktop air purifier with DLGTUVDL) uses a turbo blower with an air filter to draw in outside air to be disinfected through its specially designed double-layer glass tube ultraviolet disinfection lamp.

The ultraviolet disinfection lamp of the desktop air purifier has a double-layer glass tube with an inner glass tube and an outer glass tube. The center of the inner glass tube is a hollow space for external air to pass through and receive UV disinfection. This unique design allows ultraviolet rays to surround the entire hollow tube space to provide 360-degree ultraviolet radiation and disinfection at a close distance without dead ends, which greatly improves the disinfection efficiency.

In addition, the desktop air purifier with DLGTUVDL has the function of natural plant scent air purifying agent to provide the disinfected air that carries the natural plant scents.

The present invention relates to an HVAC system scented air filter. The scented air filter is configured to secure to an HVAC vent or along the ductwork connected thereto. The air filter includes a pair of air filters for filtering air and a scented layer removably disposed between the pair of air filters. The scented layer can be infused with fragrance and includes a plurality of evaporating fragrance gel discs for dispensing fragrance through the filter. The air filter provides a reminder system, or useful/active life indicator, to notify an owner to change the filter when the fragrance is diminished. The filter can provide an electronic nose sensor to detect fragrance in blowing air or a timer button can provide a reminder to the user to replace the filter. Alternatively, a QR code can be used for reminding the user to replace the filter.

An indoor external air filtering and fragrance diffusing system composed of a cage like apparatus that attaches to an existing air vent and holds in place air filter. The present invention includes a device to hold a filter from the exterior of a conventional air vent, allowing the airflow into a room from the central air system and a customized air filter. The present invention incorporates a variety of air filters that can be adapted to the specific needs of a user. One variation of the filter contains an embodiment that is comprised of absorbent material where a fragrance of choice can be added. Yet another variation of the filter contains an embodiment of absorbent material that already contains fragrance.
