The present disclosure relates to air assemblies having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, the present disclosure relates to air assemblies where the configuration of the air assembly can be changed manually by a user by operating a directional control valve to inflate, deflate, or close the inflatable product. The directional control valve may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.

An electric component mounting unit for an air-conditioned garment, which is used in combination with a garment body having a fan opening and which is mounted on a body, includes a fan which takes air from outside into the garment body, a mounter which mounts the fan on the body, and a fan attacher which attaches the fan to the mounter. The fan includes a fan-side linker which links the fan with the fan opening.

A ceiling-inserted fan includes a case having an air inlet on a bottom surface of the case and an air outlet on a side surface of the case, an adapter plate having a rectangular opening and forming at least part of the side surface of the case, a duct-connecting adapter protruding outward the adapter plate and an air-sending part for directing air from the air inlet to the air outlet. The duct-connecting adapter is separated from the adapter plate and includes a sealing section that contacts with a peripheral section of the rectangular opening inside the case and a locking section that contacts with the peripheral section of the rectangular opening outside the case. The sealing section and the locking section removably holds the peripheral section.

The present disclosure provides an inflation product with a built-in air pump, including an air pump (1), a connection piece (2) and an inflation product (15). The inflation product (15) includes a through hole (151) penetrating from inside to outside, the connection piece (2) is fixed at an opening of the through hole (151), the air pump (1) and the connection piece (2) are detachably connected, and the through hole (151) is provided for the air pump (1) to protrude into with a front end of the air pump (1) exposed outside the through hole (151). The front end of the air pump (1) includes an air inlet (3) in which a normally-closed switch is mounted, and an air inlet sealing cover (5) for driving the normally-closed switch (4) to be pressed down is covered on the air inlet (3).

A fan engagement structure for the fan to quickly and securely plug into or extract out of another structure. The fan engagement structure includes a frame main body. The frame main body has a first end and a second end. The frame main body has an internal hollow passage. The first end is mated with a fan. The frame main body has a first side and a second side. An engagement elastic plate extends from the first side. The surface of the engagement elastic plate has a latch section. The second side has a finger latch section, whereby the fan can be quickly and securely plugged into or extracted out of the other structure.

An attic fan assembly having a cover, a housing, and a flashing. The housing having a first opening, a second opening, and a sidewall positioned between the openings. The sidewall having a plurality of apertures that can be positioned in a variety of configurations. A motor and fan blade assembly can be located within the housing. The flashing and the cover of the attic fan assembly can be removably attached to the housing. The flashing can be used to secure the attic fan assembly to the roof of a structure.

An air circulator which is attached to a sheet member and which is for generating an air flow from one side of the sheet member to another side of the sheet member includes a fan main body and a ring member for attaching the fan main body to the sheet member. The fan main body includes a hollow cylinder unit, a flange formed on the cylinder unit, a motor fixing unit, a motor fixated to the motor fixing unit, a wing attached to a rotating shaft of the motor and first engaging units formed on outer surfaces of first parts of the cylinder unit, the first parts forming a pair and facing each other. The ring member includes second engaging units which are formed on inner surfaces of second parts that form a pair, the second parts facing each other, and which engage with the first engaging units.

A ventilation assembly having a main housing that can be pre-installed in a wall or ceiling aperture. A fan assembly can be inserted through the aperture and releasably mounted within the main housing. The fan assembly can be removed from the main housing and replaced without removing the main housing from the wall or ceiling. An accessory component can be releasably mounted to the fan assembly either through the aperture when the fan assembly is mounted or prior to installation of the fan assembly.
