A readily transportable, compact and self-contained drain cleaning apparatus includes a hand-held control housing that is provided with an internal passage into which a release member and an adjustable regulating unit extend at spaced intervals such that a fluid chamber is defined between the release member and the regulating unit within the internal passage. The control housing includes a cartridge housing portion for attaching a miniature cartridge, containing a pressurized gaseous medium and preferably either a drain cleaning or algaecide fluid, thereto with an interior of the cartridge opening into the internal passage downstream of the regulating unit. Upstream of the release member, the control housing has an elongated tube attached thereto and the tube has an end, remote from the control housing, provided with a terminal discharge member that is adapted to be sealingly engaged with an open portion of a clogged drain conduit. With this construction, shifting of the release member causes a supply of pressurized fluid, delivered into the fluid chamber from the pressurized cartridge through the regulating unit, to flow through the tube and terminal discharge member and into the drain conduit as a momentary burst of pressurized fluid while the regulating unit retards a flow of additional pressurized fluid from the cartridge to the fluid chamber.

[ I claim:] [1.] A portable drain cleaning apparatus comprising:a control housing adapted to be grasped by and held in a user's hand, said control housing being provided with a fluid passage therein;a release valve member disposed, at least in part, within said passage, said release valve member being movable between at least a first position wherein said release valve member prevents fluid from flowing within said passage and a second position wherein fluid is permitted to flow therein;a flexible, tubular member having first and second end portions, the first end portion of said tubular member being attached to said control housing, downstream of said release valve member, with an interior of said tubular member opening into said fluid passage;a terminal discharge member provided at the second end portion of said tubular member, said terminal discharge member being adapted to be sealingly engaged with an open end of a drain conduit and including an outlet opening in fluid communication with said fluid passage through said tubular member; andmeans for pressurizing said fluid passage upstream of said release valve member, said pressurizing means including a miniature cartridge, sized to substantially fit in the palm of a hand, that is pre-charged with a gaseous medium, wherein placement of said terminal discharge member at the open end of a drain conduit and shifting of said release valve member from said first position to said second position causes pressurized fluid in said fluid passage to flow through said tubular member and into the drain conduit in order to clean the drain conduit.
