Abstract
A dental cleaning apparatus is configured as a hand-held unit. The appliance includes a housing body having an interior housing cavity. The housing cavity includes an upper compartment configured to receive a volume of cleaning composition within or in absence of a container. The container may be permanently fixed in the interior housing cavity of the housing body or may be removable and replaceable through an uncoverable side opening in the housing body The housing cavity also includes a lower compartment configured to receive a pressurized air canister. An elongated hollow nozzle assembly is mounted to an upper end section of the housing body and has a nozzle conduit providing fluid communication between the cleaning composition and a tip section of the hollow nozzle assembly.
Claims20
A portable handheld pressurized dental cleaning apparatus, comprising:
- a housing body defining an interior cavity having an upper compartment and a lower compartment;
- an elongated hollow nozzle assembly mounted to said housing body and having a proximal end and a distal end, said proximal end being disposed in fluid communication with said upper compartment of said housing body interior cavity, said distal end terminating outside of said housing body;
- a volume of cleaning composition contained within said upper compartment of said housing body interior cavity, said proximal end of said hollow nozzle assembly being in fluid communication with said cleaning composition;
- a self-contained pressurized air cartridge disposed within said lower compartment of said housing body interior cavity;
- and
- an actuator mechanism connecting said pressurized air cartridge in said lower compartment of said housing body interior cavity to said cleaning composition in said upper compartment of said housing body interior cavity, said actuator mechanism being selectively activated at an exterior location on said housing body to controllably actuate and enable fluid communication of pressurized air from said pressurized air cartridge to said volume of cleaning composition in said upper compartment of said housing body interior cavity so as to thereby cause pressurized flow of portions of said cleaning composition into said proximal end of said hollow nozzle assembly and from said distal end of said hollow nozzle assembly.
A portable handheld pressurized dental cleaning apparatus, comprising:
- a housing body defining an interior cavity having an upper compartment and a lower compartment;
- an elongated hollow nozzle assembly mounted to said housing body and having a proximal end and a distal end, said hollow nozzle assembly having an elongated hollow nozzle conduit extending between an inlet aperture at said proximal end of said hollow nozzle assembly and an outlet aperture at said distal end of said hollow nozzle assembly, said proximal end inlet aperture being disposed in fluid communication with said upper compartment of said housing body interior cavity, said distal end outlet aperture being disposed outside of said housing body;
- a container disposed within said upper compartment of said housing body interior cavity and being configured for holding a volume of cleaning composition, the proximal end inlet aperture of said hollow nozzle assembly being in fluid communication with said volume of cleaning composition in said container;
- a self-contained pressurized air cartridge provided within said lower compartment of said housing body interior cavity;
- and
- an actuator mechanism connecting said pressurized air cartridge in said lower compartment of said housing body interior cavity to said container in said upper compartment of said housing body interior cavity, said actuator mechanism being selectively activated at an exterior location on said housing body to controllably actuate and enable fluid communication of pressurized air from said pressurized air cartridge in said lower compartment to said volume of cleaning composition in said container in said upper compartment so as to thereby cause pressurized flow of portions of said cleaning composition into said proximal end inlet aperture of said hollow nozzle assembly and from said distal end outlet aperture of said hollow nozzle assembly.
A portable handheld pressurized dental cleaning apparatus, comprising:
- a housing body having an upper shell portion and a lower receptacle portion detachably attached to said upper shell portion and together defining an interior cavity, said upper shell portion defining an upper compartment of said housing body interior cavity, said lower receptacle portion defining a lower compartment of said housing body interior cavity;
- an elongated hollow nozzle assembly mounted to said upper shell portion of said housing body and having a proximal end and a distal end, said hollow nozzle assembly having an elongated hollow nozzle conduit extending between an inlet aperture at said proximal end of said hollow nozzle assembly and an outlet aperture at said distal end of said hollow nozzle assembly, said proximal end inlet aperture of said hollow nozzle assembly being disposed in fluid communication with said upper compartment of said housing body interior cavity, said distal end outlet aperture of said hollow nozzle assembly being disposed outside of said housing body;
- a container disposed within said upper compartment in said upper shell portion of said housing body and being configured for holding a volume of cleaning composition, said proximal end inlet aperture of said hollow nozzle assembly being in fluid communication with said volume of cleaning composition in said container;
- a self-contained pressurized air cartridge provided within said lower compartment in said lower receptacle portion of said housing body;
- and
- an actuator mechanism connecting said pressurized air cartridge in said lower compartment to said cleaning composition container in said upper compartment, said actuator mechanism including a pressure regulator and a release valve, said pressure regulator supported at and extending below a lower end of said upper shell portion and in fluid communication with the pressurized air cartridge, said release valve being supported by said upper shell portion between said pressure regulator and said container such that said release valve is connected in fluid communication with said pressure regulator and said container and is selectively activated at an exterior location on said housing body adjacent to said upper shell portion to controllably actuate and enable fluid communication of pressurized air from said pressurized air cartridge in said lower compartment to said volume of cleaning composition in said cleaning composition container in said upper compartment so as to thereby cause pressurized flow of portions of said cleaning composition into said proximal end inlet aperture of said hollow nozzle assembly and from said distal end outlet aperture of said hollow nozzle assembly.
