Claim 7

A dental cleaning device comprising a pressurized gas cartridge, a liquid reservoir, a nozzle member carried by said reservoir, and communicating with the lower part thereof a manually operable valve normally biased to a closed position and including a first outlet communicating with said reservoir and a first inlet, means for connecting said valve inlet to a gas cartridge, and a liquid actuated pulsating device disposed between the outlet of said nozzle member and said reservoir.

Claim 8

A dental cleaning device comprising a pressurized gas cartridge, a liquid reservoir, a nozzle member carried by said reservoir, and communicating with the lower part thereof, a manually operable valve normally biased to a closed position and including a first outlet communicating with said reservoir and a first inlet, means for connecting said valve inlet to a gas cartridge, and a housing secured to and positioned end to end with said reservoir and defining a handle therewith, said nozzle being mounted on to the outer end of said reservoir, said valve including a tubular body member positioned in and extending across said reservoir and having longitudinally spaced first inlet and outlet ports defining said first inlet and outlet respectively, a valve shaft longitudinally movable in said body member between alternative first and second positions respectively closing and opening communication between said first inlet and outlet ports and normally biased to said first position and provided with a pushbutton projecting from said shaft outwardly of said valve body member and reservoir, and said cartridge connecting means including a piercing tube projecting into said housing and communicating with said valve first inlet.

Claim 9

A dental cleaning device comprising a pressurized gas cartridge, a liquid reservoir, a nozzle member carried by said reservoir, and communicating with the lower part thereof, a manually operable valve normally biased to a closed position and including a first outlet communicating with said reservoir and a first inlet, means for connecting said valve inlet to a gas cartridge, and a housing secured to and positioned end to end with said reservoir and defining a handle therewith, said nozzle being mounted on to the outer end of said reservoir, said valve including a tubular body member positioned in and extending across said reservoir and having longitudinally spaced first inlet and outlet ports defining said first inlet and outlet respectively, a valve shaft longitudinally movable in said body member between alternative first and second positions respectively closing and opening communication between said first inlet and outlet ports and normally biased to said first position and provided with a pushbutton projecting from said shaft outwardly of said valve body member and reservoir, and said cartridge connecting means including a piercing tube projecting into said housing and communicating with said valve first inlet.

Claim 10

The dental cleaning device of claim 6 wherein said valve body member has longitudinally spaced second inlet and outlet-defining ports formed therein, communication between said second ports being alternatively closed and open by said valve shaft when in said first and second positions respectively, said second outlet port being connected to said nozzle and said inlet port communicating with the lower part of said reservoir.

Claim 11

The dental cleaning device of claim 6 wherein said valve body member has longitudinally spaced second inlet and outlet defining ports formed therein, communication between said second ports being alternatively closed and open by said valve shaft wheN in said first and second positions respectively, a first tube directed upwardly from said valve body member coaxial with said reservoir and communicating with said second outlet port, said reservoir having an opening in the top thereof, a cap member releasably engaging said opening, said nozzle being mounted on and projecting through said cap member and terminating at its bottom in a second coupling tube releasably engaging said first coupling tube.

Claim 12

The dental cleaning device of claim 6 wherein said housing is open at its bottom and includes an upper wall abutting sand reservoir bottom wall, a casing member projecting through said housing and reservoir abutting walls and secured thereto and having a pressure regulator valve housed therein, said piercing tube being coaxially formed with said casing member and depending therefrom, an externally threaded peripheral wall depending from and integrally formed with said casing member, a magazine member supporting said cartridge in engagement with said piercing tube and engaging said threaded peripheral wall, a first tube positioned in said reservoir and extending between said casing member bore and said valve first inlet and a second tube extending from said valve first outlet to the lower part of said reservoir.
