The floater is mounted on the base of the water tank, the structure in the atomizing water channel is simplified, the cleaning difficulty of the atomizing water channel is reduced.

A humidification and air cleaning apparatus is provided, in which a first sweep angle and a second sweep angle are formed at diffuser blades, and an included angle is formed between the first sweep angle and the second sweep angle, such that a phase difference is formed in air passing through the diffuser blades, and thus, air flow noise may be reduced.

An air purifier capable of adjusting wind directions according to an embodiment of the present invention comprises: a housing having an air outlet port on one side thereof; an air guide having a front end portion disposed at the center of the air outlet port such that the air outlet port becomes a ring shape and a rear end portion extending in a direction toward the other surface of the housing and coupled to the inside of the housing so as to be rotatable in a direction inclined with respect to the air release direction of the air outlet port; and a rotation-restraining portion for restraining the rotation of the air guide by elastically supporting the air guide on the housing.

The present invention provides a foldably packed temperature adjustment fan, which comprises a water tank assembly, having a water storage cavity; and a shell assembly, mounted on a top of the water tank assembly, wherein the shell assembly comprises a plurality of side plate assemblies for surrounding and forming an airflow cavity and a top plate assembly, at least a part of the side plate assemblies are respectively utilized as a whole body and are detachably mounted on an edge of the top of the water tank assembly, and at least a part of the side plate assemblies can be completely accommodated in the water storage cavity after being detached. The present invention further provides a folding method of the foldably packed temperature adjustment fan. When the temperature adjustment fan of the present invention is used, its appearance is the same as that of a normal unit; during packing, a rear plate assembly, a left side plate assembly and a right side plate assembly can be completely accommodated in the water tank assembly, a front panel assembly does not need to be detached, and as long as the front panel assembly is turned over, fast folding is completed; and the package size is small, associated components are less, and logistics transportation is convenient.

A steam room for sanitizing people's external body parts and clothes, but also their breathing airways and respiratory tract, to reduce viral load and thereby mitigate the likelihood of spreading or contracting Viral contamination. Steam room has precise temperature and relative humidity control of a heater and mist generator, in which the mist water molecules contain an accurate concentration of a Chlorine or Ethanol based disinfectant, so that the water vapor or combined air/water mixture in the room that comes in contact with the sanitized person reaches but does not surpass the globally permitted concentration of free Chlorine for swimming pools, dressing rooms and spas. The room has thermally isolated quick doors allowing rapid entry and exit, and the signaling to guide the person when to enter, stay and breath, and exit, in the most suitable timing profile for the application.

A humidification and air cleaning apparatus is provided, in which a wave having a predetermined cycle is formed on a plurality of blades of a blower fan, such that operating noise caused by a flow of discharged air may be minimized, and a wave is formed at a trailing edge, such that a phase difference may be formed for air to be separated, and air flow noise of the discharged air may be reduced.
