DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0026] With reference to FIG. 1, an embodiment of a compact oral hygiene device 100 generally comprises a body 110, a reservoir 130, tips 150, 160 and a handle 140.
[0027] With reference to FIG. 1-1, the body 110 is housing a rechargeable battery 112, a mini constant jet pump 120 and control circuitry 113.
[0028] The mini constant jet pump 120 is a unique mini pump for the compact oral hygiene device 100. The mini constant jet pump 120 is integrated with a motor 121 as show in FIGS. 3, 3-1 and 4. The mini constant jet pump 120 comprises three diaphragm chambers 126-1, 126-2 and 126-3. The mini constant jet pump 120 further comprises a lever 50 with three arms mounted at the bottoms of those three chambers 126-1, 126-2 and 126-3. The lever 50 comprises a center pole 51 which eccentrically inserts into a rotating arm 60. The rotating arm 60 is mounted at the axis of the motor 121 and rotating by the motor 121. During the motor 121 rotating, the lever 50 did not rotating but the three arms of the lever 50 are oscillating at one going down with two others going up caused the volume of the chambers 126-1, 126-2 and 126-3 are decreased and increased.
[0029] With reference to FIG. 4, the rotating arm 60 is rotated with the motor 121, the center pole 51 of the lever 50 eccentrically inserts into the rotating arm 60 caused one arm of the lever 50 is going down; and pressing the diaphragm of the chamber 126-1 down and the volume of the chamber 126-1 is decreased; the fluid in the chamber 126-1 is propelled out from the outlet check valve 127-1 into the buffer room 129. And the inlet check valve 128-1 is closed. Meanwhile, other arms of the lever 50 are going up; and pressure released caused diaphragm of the chamber 126-2 goes back to the original shape and the volume of the chamber 126-2 is increased; the inlet check valve 128-2 is open and fluid is drawn into the chamber 126-2. And outlet check valve 127-2 is closed.
[0030] The above circulation repeats during the motor 121 running. The mini constant jet pump 120 draws fluid three times from the reservoir 130 through an inlet 124 into each chamber 126-1, 126-2 and 126-3 during one circle of the motor 121 rotating. Meanwhile, the fluid propels out from an outlet 123 of the mini constant jet pump 120 as a constant pulseless fluid jet.
[0031] With reference to FIG. 1 and FIG. 1-1, the mini constant jet pump 120 draws the fluid from the reservoir 130 through an inlet hose 115 then ejects out a constant pulseless fluid through an outlet hose 114. Then fluid flows into the handle 140 through a soft hose 141 and ejects out from a tip 150 into user's mouth for oral hygiene. The body 110 can be stored inside of the reservoir 130 after the usage.
[0032] With reference to FIG. 2, another embodiment of a compact oral hygiene device 200 generally comprises a body 210, a reservoir 230, tips 150 and 160. The body 210 is housing a mini constant jet Pump 120, a 2.4-3V battery and a circuitry. The tip 150 directly connects to the outlet of the body 210. The body 210 can be stored into the reservoir 230 after the usage.
[0033] For general users, a Waterjet Brush tip is recommended. With reference to FIG. 6, the Waterjet Brush tip 160 comprises a toothbrush head 161 at the hygiene end of the tip, a tip body 162, a groove 164, an inlet 163, two nozzles 161a and bristle tufts 161b in the toothbrush head 161. The Waterjet Brush tip 160 further comprises a conduit from the inlet 163 to inside of the tip body 162 then to the lower layer of the toothbrush head 161 then fluidly connects to the nozzles 161a. The nozzles 161a are shaped a narrowed top conical hose. The two nozzles 161a are located at the crosses of the front and the side edges of the toothbrush head 161. The location of nozzles 161a allow user to figure out where is the nozzle 161a during usage. The nozzles 161a are shorter than the bristle tufts 161b to avoid the nozzle to be blocked and ensure the core of the water jet is on user's teeth surface. The bristle tufts 161b are stably support nozzles 161a staying and cleansing a location for a while. For example, user can use nozzle 161a to blast white spot lesion to destroy the white spot lesion's developing environment for couple seconds. This kind of performances were done by a third party using a water jet in a laboratory and removed 99.9% plaque but never achieved by a user. User could also use the nozzles 161a penetrating to dilute the acid for avoid lesion. The nozzles 161a eject water jet to cleansing and the bristles 161b brushing the teeth and interdental simultaneously.
[0034] For user who has gum disease a Swirl Waterjet tip 150 is recommended. With reference to FIG. 5, The Swirl Waterjet tip 150 comprises a pipe 151 which has a close off end, a cap 152 with internal thread and a pinhole 152a centrally located at the top of the cap 152, a swirl generator 153a-153b, a ring gasket 154, an external thread 155 that matches internal thread of the cap 152, an inlet 156 and a groove 157. The swirl generator 153a-153b is at the close off end of the pipe 151 and comprises two holes 153a located opposite each other in the side of the pipe 151 and divides a single fluid flow to two. When the cap 152 is screwed onto the pipe 151, the two fluid flows are blocked by the ring gasket 154 then water flows through the two lifting lines 153b which located on the close off end of the pipe 151. For the sake of the clarity the two lifting lines 153b are parallel but do not pass through the center of the close off end of the pipe 151. When the cap 152 is screwed slightly loose against the pipe 151, a water jet stream is ejected out and deep cleans the interdental area. When the cap 152 is screwed tighten against the pipe 151, two water flows twists out from the pinhole 152a to form a high speed rotating umbrella shaped water wheel which opens a user's periodontal pocket to washout plaque therein. The high speed rotating umbrella shaped water wheel also generates a low pressure zone and suck out plaque in deep of user's periodontal pocket.
[0035] With reference to FIG. 7 and FIG. 7-1, an embodiment of the Jet Goupillon tip 170 comprises a front bristle tuft 175, side bristle tufts 171, a pinhole 176, a tip body 172, a groove 174 and an inlet 173. The Jet Goupillon tip 170 further comprises a conduit from the inlet 173 to inside of the tip body 172 and fluidly connects to the pinhole 176. The layout of the bristles 171 likes a goupillon. The side bristles 171 are gradually shorter forward to front and enable to clean the narrowed portion inside trays or retainers such as Invisalign. The front bristle tuft 175 and side bristle tufts 171 plus water jet from pinhole 176 could clean aligners, retainers, dentures and artificial teeth for orthodontic and dental treatment patients.
