A device for mosquito repellents, including a support structure having a first end arranged to be positioned on a surface, and a second end opposite the first end, the distance between the first end and the second end defining a height H of the support structure. The device further includes a first plate arranged at the second end of the support structure perpendicularly to a direction of height of the support structure, the plate being void of openings and suitable for receiving a heated mosquito repellent. The device still further includes a fan attached within the support structure, between the first end and the second end of the support structure, to blow air from the first end towards the second end of the support structure and the first plate, and means for operating the fan. The size and shape of the first plate is such that it covers the fan, when seen from the second end of the support structure in the direction of height of the support structure.

An oxygen generator outlet manifold assembly that includes an outlet manifold and an end cover. The outlet manifold includes a main body portion with inner and outer surfaces and at least a first hose connector that includes an outlet defined therein extending from the main body portion. The main body portion defines a main body portion interior that includes a connection opening defined in the inner surface, a ring chamber, a flow space and a distribution chamber. An annular ring is positioned in the main body portion chamber interior and separates the ring chamber from the distribution chamber. The end cover includes a generator outlet portion extending therefrom that is received in the connection opening. The generator outlet portion includes an outlet valve having an open and a closed state and includes an interior chamber that cooperates with the ring chamber to define an outlet chamber. An oxygen flow path is defined through the open valve, to the outlet chamber, through the flow space, through the distribution chamber and to the outlet of the first hose connector.

A mask device includes a mask body including a front cover to form an outer appearance of the mask body, a frame coupled to the front cover, the frame located in front of a user's nose and mouth when the mask device is worn by the user, and a flow path between the front cover and the frame. A first air cleaner is disposed on one side of the mask body and a second air cleaner is disposed on another side of the mask body, and a first fixing part couples the first air cleaner to the mask body and a second fixing part couples the second air cleaner to the mask body. The first air cleaner is movable with respect to the first fixing part to move towards the frame and the second air cleaner is movable with respect to the second fixing part to move towards the frame.
