When any one in pattern 1 to 3 or 6 is selected, control circuit 58 activates motor 56 with by the phase of brush unit 29 For handle 12 is moved with brushing teeth 300 (as shown in Figure 21), brush unit 29 is pushed down against tooth by user.Driving machine Structure 50 and motor 58 are configured to produce brush carrier 30 around nozzle 36 with the speed in the scope from 4000 to 6000 rpms Degree motion, wherein per the single 360 ° of rotations for turning to be crank 78, and be thus single 360 ° rail of the brush carrier 30 around nozzle 36 Move in road.

When any one of pattern 2 to 6 is selected, first control circuit 58 runs pump 106 to fill accumulator 108. Solenoid valve 114 in a closed position in the case of, pump 106 is run a lasting period time and (is about in this embodiment 500 milliseconds) to aspirate the water of a volume from fluid storage 34, and the water being sucked of the volume is transported to into accumulator 108. In this embodiment, the volume of the water that each time period being run in pump 106 aspirates from fluid storage 34 is for about 0.25 Milliliter.When the water of the volume is received by accumulator 108, the hydraulic pressure in the fluid cavity 182 of accumulator 108 is about 5.5 bars (about 550kPa).Once expiry time period, or in response to being pointed to accumulator 108 in the reception of output that produces of sensor, pump 106 can be closed by control circuit 58.The water of the volume is sent to after accumulator 108, and the second check valve 112 is in close stance Put to prevent water from returning to pump 106 from accumulator 108.

When pattern 2, pattern 4, or pattern 6 are easily selected by a user out, and response user presses the button 18, and a burst of water is by from nozzle 36 Transmitting.Pressing for button 18 is detected by control circuit 58.The coil 216 of the activation solenoid valve 114 of control circuit 58 is with by spiral shell Spool valve 114 moves to open position.This allows the piston 186 of accumulator 108 to move rapidly towards fluid port 180, with The water for forcing the volume is sprayed in the form of the water by jet flow from accumulator 108.The water of the volume is compeled from accumulator 108 The time spent in going out preferably in 1 to 50 millisecond of scope, and about 30 milliseconds in this embodiment.The quick-fried stream of water through Solenoid valve 114 and burnisher pipe-line system 118 are with the ejection from the fluid issuing of nozzle 36.When nozzle 36 is positioned in tooth Between in gap or when aligning, the quick-fried stream of water sprayed from nozzle 36 can displace the material in interdental space.

Control circuit 58 is arranged in the quick-fried stream of water and is transported to supplementary accumulator after burnisher pipe-line system 118 108.The control circuit 58 is arranged to for solenoid valve 114 to move to closed position, and operate pump 106 with by another strand of water from Fluid storage 34 is transported to accumulator 108.The control circuit 58 is configured to respond to user and presses the button 18, and disables helical The opening of pipe valve 114 until accumulator 108 supplement full water, and thus upper one water from nozzle 36 transmitting after it is disabled about 500 milliseconds of time period.

When pattern 3, when pattern 5, or pattern 6 are easily selected by a user, water it is quick-fried stream according to from sensor 250 output and by from Nozzle 36 is launched.Thus, when pattern 6 is chosen, one water is pressed according to the output from sensor 250 or response user Button 18 and launch from nozzle 36.Figure 21 (a) schematically shows utensil 10 and be used to clean the tooth 300 of user to 21 (f). When tooth of the passive movement of brush unit 29 across user, the tooth of the end engaging user of nozzle 36.When nozzle 36 against with The tooth at family is applied to the power of nozzle 36 and overcomes and is applied to first fluid pipeline 230 by second fluid pipeline 232 when being promoted Biasing force, and thus nozzle 36 leave distal position towards it proximal position move.For example, when brush unit 29 move across When crossing such as tooth 302, nozzle 36 will be pressed against relative to the position of bar portion 26 according to the profile of tooth 302 and by head 28 The power of tooth 302 and change.
