DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) With reference to FIGS. 1-1 and 1-2, an oral hygiene apparatus 100 generally comprises a water supply part 10, an oral hygiene-ware part 20 and water utility part 30.

(10) The water supply part 10 may have a pair of hoses 11 and 12, a mixer valve 13 and an outlet 14. The hoses 11 and 12 connect to cold and hot water suppliers 01 and 02, respectively, from a water supply and coupled to the mixer valve 13. The mixer valve 13 will mix the cold and hot water, controls water temperature and control water flow rate. The mixed water will flow out at an outlet 14. The outlet 14 will connect to the oral hygiene-ware part 20 and the water utility 30. For example, a shower water supply that is built into a wall can be used as the water supply part 10.

(11) The oral hygiene-ware part 20 may have a soft hose 21, a handle 22 and exchangeable tips 25. The soft hose 21 should be flexible with proper diameter and long enough for oral hygiene purpose. The soft hose 21 diameter is preferably between 2 mm to 1.5 cm. The soft hose 21 length is preferably between 50 cm to 2 m. The soft hose 21 connects to the outlet 14 of the water supply part 10 to receive the mixed water. The handle 22 is coupled to the soft hose 21. The handle 22 has a built-in valve 23 and a quick connector 24. The built-in valve 23 in the handle controls mixed water flow rate and can shut off the water flow. The quick connector 24 has a mechanism that can quickly exchange the exchangeable tips 25. The mixed water will flow through the handle 22 and pass through the quick connector 24 and then through the exchangeable tips 25 out to the mouth of user. Each exchangeable tip 25 has special oral hygiene functions. For example, the swirl waterjet tip 251 could generate a waterjet beam and a swirl waterjet, FIG. 3-3. The swirl waterjet can do deep dental cleansing even inside the periodontal pocket. The waterjet brush tip 255 has nozzles 552 and bristle tufts 551 in the head of the tip, refers to FIG. 3-4. The waterjet ejected from the nozzles 552 and brushing by the bristle tufts 551 will significantly increase cleansing the plaque on the teeth especially in the interdental area. Nozzles 552 should have a height of 0.2-4 millimeters less than the bristle tufts 551 that can vary in length from 5-15 millimeters preferably 10 millimeters. Further, the opening at the end of the nozzle 552 is 0.3-0.8 millimeters in diameter. The waterjets described herein are intended to have a force of 60-200 PSI. The nozzle 552 is shorter than the bristle tufts to maximize the accuracy of the waterjets and help guide a user to avoid placing the waterjet onto the or below the gumline.

(12) The mixed water from water supply part 10 flows into the oral hygiene-ware 20 and then ejects out from the exchangeable tip 25 into the month of user to perform oral hygiene functioning.

(13) The water utility part 30 may have a hose 31, a pipe 32, a valve 33 and connector 34 which connects to a utility head 35. The hose 31 connects to the outlet 14 of the water supply part 10 and pipe 32. The pipe 32 will deliver the water to the utility head 35. There is valve 33 installed in the pipe 32 and controls water flow rate. The valve 33 could be installed in any portion of the water utility part 30. The connector 34 in the end of the pipe 32 could connect the utility head 35. The utility head 35 could be a filter, nozzles, showerhead etc.

(14) The mixed water from the water supply part 10 flows into the water utility 20 then flows out for water utility purpose.

(15) With reference to FIG. 2, it shows an embodiment of oral hygiene apparatus 200. The oral hygiene apparatus 200 could be installed in a bathroom as a sink fixture. The oral hygiene apparatus 200 may have a water supply that comprises hoses 11 and 12. The hoses 11 and 12 could connect water supplies 01 and 02 from a wall mounted valve to receive cold and hot water. The hoses 11 and 12 coupled with mixer valve 13. The water mixer valve 13 adjusts water temperature to a proper temperature for the user. The water flow rate could also be controlled by the mixer valve 13. The mixed water will flow out at the outlet 14 to oral hygiene-ware 20 and water utility 30.

(16) The oral hygiene apparatus 200 may have an oral hygiene-ware that comprises hose 21. The mixed water from the outlet 14 will flow into the hose 21. The hose 21 is coupled to the handle 22. There is a built-in valve 23 that is inside the handle 22. The built-in valve 23 could control the mixed water flow out pressure by adjusting the flow rate. At a proximate end of the handle 22 may have a quick connector 24 which could quickly exchange exchangeable tips 25. The mixed water will flow from handle 22 to the exchangeable tip 25 out to the user's mouth. Various tips may be available for oral hygiene functioning.

(17) FIG. 3-2 depicts some exchangeable tips 25 but is not intended to be limiting. Such as swirl waterjet tip 251, refers to FIG. 3-3; rotatable brush tip 252; gumline brush tip 253; an interdental brush tip 254 and waterjet brush tip 255, refers FIG. 3-4.

(18) The oral hygiene apparatus 200 may have a water utility that comprises a hose 31, a valve 33, pipe 32, connector 34 and utility head 35. The mixed water from the outlet 14 will flow into the valve 33 in the water utility. The valve 33 connects to the hose 31 that is coupled to the pipe 32. The valve 33 may shut off automatically by raising the handle 22. The pipe 32 will deliver the water to utility head 35. At the proximal end of the pipe 32 may have a connector 34 for mounting the utility head 35.

(19) To use the oral hygiene apparatus 200 for oral hygiene the user should first select an exchangeable tip. The tip 255 is recommended for general cleaning. If the user has periodontal disease the tip 251 should be used after the tip 255. After a user selects a tip and installed in the handle 22, user should turn on the mixer valve 13 and check the water temperature from out of the utility head 35. When the temperature is preferred, raising the handle 22 and the arm 333 will lift, FIG. 4. The lifted arm 333 will shut off the valve 33 and no more water will flow out from the outlet 334c. When the lifted arm 333 is lifted, water flow to the utility head 35 is stopped, FIG. 4. Then the user can use the hygiene-ware freely.

(20) The tip 255 has nozzles 552 and bristle tufts 551 in the head of the tip 255. The nozzles 552 will eject a waterjet. The tip 255 has a connector 553 and water inlet 554 refers to FIG. 3-4. The nozzles 552 are narrowed top conical tube made of elastomer or flexible material. The nozzles 552 can detect the position on the teeth to directing waterjet & brushing and avoid bristle tufts 551 from passing beyond the gumline to harm the gum.

(21) For a user who has periodontal disease the tip 251 is recommended. The tip 251 comprises tube 512 and cap 511 with one hole 511a in the cap 511 refers to FIG. 3-3. There is a swirl waterjet generator 513 in the front of the tube 512. There are two holes 513a to allow water out from tube 512 then through two parallel tangent lines 513b out to cap 511. For the sake of clarity the two holes 513a are parallel but do not pass through a diameter of the swirl waterjet generator 513. Water exiting from tangent lines 513b twist relative to one another causing a swirl waterjet. When the cap 511 is screwed tightly onto the tube 512, a swirl waterjet will eject out from the hole 511a. When the cap 511 is screwed onto the tube 512 in a slightly loose position, the waterjet beam will eject out from the hole 511a. Water will flow into tube 512 from handle 22 then through the swirl waterjet generator 513 to eject waterjet beam or swirl waterjet to mouth of user to cleansing gingival area and dental pockets.

(22) With reference to FIG. 5, it shows another preferred embodiment of oral hygiene apparatus 300. This preferred embodiment one places the valve 33 in the water utility and utility head 35. The valve 33 is a manually operated and installed at the outlet of the pipe 32. The hose 21 and hose 31 will be installed accordingly. The utility head 35 is a spray nozzle. The spray nozzle 35 could save water up to 70% than regular faucet.

(23) In preferred embodiments, the oral hygiene-ware devices will not need electricity or other energy source. It is greenness and environment friendly.

(24) Thus, specific embodiments and applications of oral hygiene apparatus have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications beside those already described are possible without departing from the inventive concepts herein.
