The present invention relates to an air scenting device, comprising a housing having an accommodation configured to enable insertion of a scent module, an air and scent perfume mixing chamber in the housing under the accommodation, configured to mix air and scent perfume from the scent module to generate scented air, and an outflow opening in communication with the chamber and an outside relative to the housing. Furthermore, the present invention relates to an assembly of a scent module and an air scenting device according to any one or more than one of the preceding claims, wherein the scent module comprises a container with a supply of perfume.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water, a visual body forming at least a portion of the water tank and formed of a transparent material, a water tank inlet formed at the water tank and communicating the inner and outer sides of the water tank, a water tank humidification medium covering the water tank inlet, formed of a water absorbing material, and providing humidification on air passing through the water tank inlet, a watering housing disposed inside the water tank, drawing water of the water tank into the inside, pumping the drawn water upwardly when rotating, and spraying the pumped water, a watering motor providing a torque to the watering housing, a lower nozzle disposed at the watering housing and spraying the pumped water to the water tank humidification medium, and a upper nozzle disposed at the watering housing and spraying the pumped water to the visual body.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; and a discharge humidification medium housing disposed over the water tank and disposed over a discharge flow passage flowing via the water tank and the water supply flow passage supplying water into the water tank. Here, the discharge humidification medium housing includes: a reservoir disposed in the water supply flow passage and storing water supplied into the water tank when water is supplied from the upper side; and a water outlet formed in the reservoir and supplying water of the reservoir into the water tank.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a watering housing disposed inside the water tank and rotating inside the water tank; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water supplied to the water supply flow passage drops on the watering housing to be scattered.

The present invention is directed to a digital aroma system that provides a scented air on demand to various devices in various forms and user held devices including: remote controls, video game controllers and mobile computing devices. Dry fragrance infused substrates are contained in fragrance cartridges that are removably mounted in a cassette that is connected to a manifold that has airway passages that are connected to fans or pumps that are controlled by a computer processor. In response to a fragrance control signal or a fragrance trigger, the processor can selectively direct scented air having a specified fragrance to a system user.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a base body including a water tank insertion space formed therein; a water tank having an upper side thereof opened, storing water therein, placed in the water tank insertion space, and separable from the base body; a top cover assembly disposed over an opened upper part of the water tank and disposed separably from the water tank; an air wash inlet formed at a side of the water tank and receiving air into the water tank; a discharge flow passage formed in at least one of the top cover assembly and the water tank, or formed between the top cover assembly and the water tank; and a water supply flow passage disposed inside the top cover assembly and guiding water into the water tank.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a reservoir disposed in the top cover assembly, disposed on the water supply flow passage, and storing supplied water; and a watering housing disposed inside the water tank and receiving a torque from a watering motor so as to be rotatable. Here, water supplied through the water supply flow passage is stored in the reservoir, and then drops on an upper part of the watering housing.

A microfluidic fluid delivery device and method. The device includes a reservoir and a transport member. The device includes a microfluidic delivery member including a microfluidic die configured to release a fluid composition from the device. The microfluidic delivery member includes an adapter configured to receive an end portion of the transport member, wherein a capillary passage is formed between the adapter and the transport member. The capillary passage has a largest effective pore size that is smaller than the average effective pore size of the transport member.

Example embodiments provide a modular air freshener system. The modular air freshener system comprises a plurality of different carriers and at least one scent device. The scent device is separately and removably carriable by each of the plurality of different carriers. At least one of the different carriers is carriable by another one of the plurality of different carriers. The each of the carriers may be passive, active and self-powered, or active and externally-powered.

An evaporative humidifier includes a main body; a reservoir provided in the main body to store water; and a humidifying element assembly rotatably provided in the main body. The humidifying element assembly includes a humidifying element which is configured to absorb water and perform humidification, and a frame to support the humidifying element, the frame including at least one guider portion which guides the water of the reservoir toward one side surface of the humidifying element.
