Abstract
Abstract This invention provides for a portable dental cleaning system which includes a lower housing (2) having an upper opening (22) and a lower opening (23). The lower housing (2) defines an internal housing reservoir for maintaining a liquid therein. The upper opening (22) is surrounded by a washer (6) which is mounted to the lower housing (2). At one end of a water faucet (7) is inserted through a central opening of the washer member (6) for insertion of water within the reservoir chamber. The lower opening (23) is threadedly secured to a liquid conduit (3) on one end of the liquid conduit (3). The liquid conduit (3) on an opposing end is coupled to a liquid passage member which egresses water through a water jet tip (5) having a water jet tip outlet (50) on one end thereof. In this manner, water is efficiently egressed into the oral cavity of a user.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
192 words
A portable dental cleaning system for controlling water velocity and pressure passing from a water jet tip member comprising: (a) a hollow apple-shaped lower housing forming an internal reservoir chamber, said lower housing having an upper substantially planar wall member having an upper through opening formed therethrough, said lower housing further including a lower wall member having a lower through opening formed therethrough, said upper through opening having mounted therein a washer member secured to said planar wall member and having a central opening formed therethrough for forced fit insert of one end of a water faucet, said lower through opening being coupled to a liquid conduit member; (b) an apple-shaped upper housing removably coupled to said lower housing, said lower housing having a shoulder adjacent said upper plane wall for matingly interfacing with said upper housing, whereby said upper housing and said lower housing are coupled when said portable dental system is non-operational to provide a substantially closed contour system when being stored; and, (c) a liquid passage member secured to said liquid conduit member for receiving liquid from said lower housing for egress through a water jet tip outlet member.
