Definitions
- the here disclosed invention refers to a tooth cleaning device and more particularly to a water jet system that removes plaques by adding soft abrasive media (besides other dental care ingredients) to the water from tabs in a mixing chamber and by transforming the jet into a particular concentric spray.
- Tooth cleaning as a daily ritual is well known to often be neglected or carried out but ineffectively, due to shortage of time.
- the first one does only avoid the need to move a toothbrush, but otherwise shows similar drawbacks when applied with too much pressure.
- the latter may rinse off foodstuff residues, but does not effectively contribute to wiping off beginning plaques, although US6.056.710 and US 6.475.173 claim to do so. This is because a therefore necessary pressure of a water jet would be irreconcilable in a sensitive area like the human oral cavity.
- An apparatus to provide effective tooth cleaning, comprising the dissolution of plaques comprising the dissolution of plaques is disclosed, wherein mildly abrasive ingredients are dispersed in a water jet.
- the system comprises a mixing cham- ber, wherein tabs of different compositions are dispersed.
- the particular dissolution process determines the application time, which therefore is naturally ascertained.
- the cleaning effect is achieved with a water jet of 10 tol5 bar, which might be branched off through a bypass of a faucet or showering mixing tap (which usually offer 5 to 8 bar) when reducing the diameter of the outlet, whereas the pressure is regulated with an automatically adjusting ring nozzle. Otherwise adequate pressure can be realized with a electrical pumping system as known from conventional water jet oral cleaners.
- the ring nozzle does provide adequate spray distribution, so to ensure a good cleaning effect without risk of hurting the gingivae.
- Said water jet as such would not sufficiently clean teeth and particularly not remove plaques. Therefore additives of mildly abrasive character, such as silicious earth (Si02) calcium carbonates or magnesium carbonates with a grading of 0.6 up to 1.5 microns are applied, which have proved to be particularly effective in removing plaques at medium or long-term application and which are harmless, even when swallowed.
- mildly abrasive character such as silicious earth (Si02) calcium carbonates or magnesium carbonates with a grading of 0.6 up to 1.5 microns are applied, which have proved to be particularly effective in removing plaques at medium or long-term application and which are harmless, even when swallowed.
- these tabs may consist of an assembly of skins with different composition or level of compaction, so as to provide alternating cleaning phases with different ingredients, or concentrations of additives due to varying dissolution times.
- Uniform flow is particularly important to ensure the constant and complete dissolution of the tab, instead of leaving residues, that otherwise would have to be cleaned off manually.
- the targeted dissolution of these tablets also provide the requested timing of dental cleaning. Unlike with coding of electric toothbrushes, which may only remind of complying with predetermined sequences of dental care, it is mandatory here due to the fact, that otherwise the rest of the tablet has to be removed and the dissolution chamber to be cleaned manually.
- the ring nozzle can be operated manually to provide an adequate water jet stream, loaded with the above mentioned ingredients.
- Fig. 1 shows the general setup, wherein the output of the bypass of a tap (not shown) is led by a flexible tube or hose 2 to the mixing chamber 3, containing the tablet 4.
- the output 5 of said chamber leads through another tube or hose 6 to the nozzle 7, which is directed to the surface of the teeth (not shown).
- Fig. 2 demonstrates the water flow within the mixing chamber 3, wherein the input water stream 10 is directed around the tablet 11, which is held within the filter grid 12, while the water stream is divided and torrented in secondary swirls 14 to 17, so to equally ablate the tablet 11 from all sides.
- Fig. 3 explains the function of the automatic ring nozzle, wherein the output of the mixing chamber (see Fig. 2) is the input 20 to the throat 21 of the nozzle, pressurizing the threaded injector 13 which can move in axial direction within the slightly bigger start-diameter 22 of the conical duct 23 against the counterpressure of the spiral spring 24, the compression of which is to be adjusted by turning the cor- rugated cap nut 25 on the injector body 26.
