The system for nano-coating a substrate (10) includes a housing (12) having an upper, dispensing chamber (18) in which electrospraying or electrospinning can occur, a lower storage chamber, and a wall (16) that separates the dispensing chamber (18) from the storage chamber. The dispensing chamber (18) includes first and second panels (24a), (24b) and a moveable collector (20) between the first and second panels (24a), (24b). Solution dispensing nozzles (26) are disposed in apertures (45) in the panels (24a), (24b), and extend from a front surface of each panel (24a), (24b). A plurality of solution supply tubes (54) extend from a rear surface of each panel (24a), (24b) to a pump (34) in the lower housing. Inner panel channels (52) are defined within each panel (24a), (24b) between the tubes (54) and the nozzles (26).

An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow.

In one aspect, provided is a liquid diffuser comprising a base, a cover and at least one duct. According to another aspect, provided is a liquid diffuser system comprising an electronic device and at least one liquid diffuser. Other example embodiments are also described. In certain embodiments, the liquid diffusers allow easy, single-hand manageable, leakage-proof and hygienic replacement of the liquid containers. In certain embodiments, the liquid diffusers provides a smart system to manage or control the time for diffusion and the type of liquid to be used in response to user's requirement and/or data collected from the environment.

BUILDING FEATURE APPLIED IN AIR-CONDITIONING APPLIANCE, capable of enriching the air with atomized water droplets in two stages, where in a first moment the water sent directly from the water supply network is pre-atomized in an appliance; being then delivered to the main atomizer, which produces the final atomization, creating an ultrafine mist that facilitates the thermal exchange between the mist and the air. The air-conditioning appliance must be associated to a fan so as to spread this mist to the room.

The present application provides an atomizer structure and an atomizer having the same. The atomizer structure includes: a spray assembly including a first cavity; a bottle body configured for containing liquid and configured to be connectable to the spray assembly, the bottle body comprises a second cavity; a first connecting member communicating the first cavity and the second cavity and configured for guiding the liquid contained in the second cavity entering the first cavity, when an air pressure in the first cavity is less than an air pressure in the second cavity; and a second connecting member selectively communicating the first cavity and the second cavity such that remaining liquid in the first cavity entering the second cavity, and configured for preventing the liquid in the second cavity from flowing into the first cavity when the atomizer structure is tilted or inverted.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).
