An air filter, particularly an air filter for an internal combustion engine, having a housing with an unfiltered air inlet and a filtered air outlet. A round filter element is sealingly disposed between the unfiltered air inlet and the filtered air outlet. In addition, an adsorber element provided with adsorbent particles is disposed on an interior wall of the housing such that the adsorber element is arranged within the round filter element.

The present invention relates to an air blowgun, and more particularly to an innovated blowpipe mechanism of the air blowgun, which can secure with variety nozzles individually for meeting to different purposes. Wherein a thread is set on the tip end of the blowpipe, thereby to connect with an extending long blowpipe, a screen nozzle, a charging adapter, a plug-in charging connector, a low-pressure nozzle, a soft nozzle, or a vent wire and so on to form multifunction tool, and it has small volum...

A device for purifying air within a room. The device includes a housing having a plurality of air inlet ports and a plurality of air outlet ports. An ultraviolet ray generator is positioned within the housing along with a fan for drawing air into the housing through the air inlet ports. A passageway leading from the air inlet ports and encircling the ultraviolet ray generator to the air outlet ports provides a path for air drawn into the housing. The ultraviolet rays produced by the generator ki...

Air cleaner including a case having an inlet and an outlet, a fan inside of the case, for drawing air through the inlet and discharging the air through the outlet, a filter assembly inside of the case for cleaning the air drawn into the case through the inlet, a heat exchanger inside of the case for heating or cooling the air drawn into the case, selectively, and a plurality of fins between the fan and the outlet for guiding the air drawn into the case to the outlet, thereby ventilating the room...

An air-freshener for a vehicle, in particular a motorcar, provided with a housing into which a container for a volatile liquid or a liquid containing one or more volatile components can be inserted, in the opening of which container a wick extending into the housing is fitted. There are further present a covering cap which, when the container with wick has been inserted into the housing, is movable up and down over the wick, and control means for setting the position of the covering cap.

An air cleaning device includes a bulb-shaped casing provided at one end with an attached portion to be attached an attaching portion and connected to a commercial power source and at the other end with an outlet, an ozone generator accommodated in the casing and an air supply portion formed in the casing for supplying air into the ozone generator. The ozone generator includes a needle first electrode having a distal end directed to the outlet and a cylindrical second electrode concentric with t...

An air compressor includes a cylinder head in which is disposed a suction valve and a discharge valve, a cylinder having an opening edge closed by the cylinder head, a piston slidably inserted in the cylinder and forming a variable volume chamber with the cylinder head, and a driving device for driving the piston in a reciprocating manner. The cylinder head includes a plate forming valve seats and ports of the suction valve and the discharge valve, and a housing accommodating the suction valve, ...

An air intake with at least one inlet port area and one outlet port area, in which there is arranged at least one structure which may be flowed through and around, comprises an opening and modifies the clear cross-section only slightly, in particular serving as a fresh air/recirculated air housing for a motor vehicle heating, ventilation and/or air-conditioning system.

The present invention is to provide an air shaft comprising a hollow cylinder and a plurality of curved members provided on an outer surface of the hollow cylinder and between both ends thereof, wherein the curved members are adapted to move radially relative to the hollow cylinder and are spaced each other with a gap formed between any two adjacent ones of the curved members. As such, no continuous straight gaps are formed on an outer surface of the hollow cylinder while pushing the curved memb...

An air cleaner is provided with a housing, a filter element disposed inside the housing for filtrating air introduced into the housing, and an adsorption element disposed in the housing for adsorbing gasified fuel in the housing, the adsorption element including an adsorbing member adsorbing gasified fuel and a frame surrounding the adsorbing member to hold the adsorbing member. The air cleaner further includes a plurality of first fusing projections projecting from one surface of the frame, a p...
