Machine 17 drives eccentric wheel 16 to rotate, and the high-speed rotation of eccentric wheel 16 drives connecting rod 14 and 13 faster reciprocal motion of piston, realization pair
Water inlet valve block 5 and water outlet valve block 10 generate suction or thrust, to control water inlet 106 and the opening and closing of water outlet 107；The battery
19 are set to 101 bottom of shell, and the motor 17 is electrically connected with battery 19, and the pcb board 18 is set to 19 side of battery, pcb board
18 are electrically connected with motor 17.
In conjunction with Fig. 1 to Figure 14, the concrete operating principle of tooth flusher provided by the invention are as follows:
Motor band 16 high speed rotation of movable eccentric wheel, the high-speed rotation of eccentric wheel 16 drive connecting rod 14 and piston 13 quick downwards
Movement, quickly movement makes the valve pump housing 113 generate inhalation power to piston 13 downwards, and water outlet valve block 10 is dynamic downwards by pump inhalation power effect
Make, be in close state water outlet 107, due to being acted on by 113 inhalation power of the pump housing, valve block 5 of intaking at this time is moved right, and is made
Water inlet 106 is opened, and Water in Water Tanks stream is sucked in the pump housing 113 at a high speed by water inlet groove 1111 and water inlet guide face 1112 at this time；
When 16 high speed rotation of eccentric wheel drives connecting rod 14 and 13 fast upward motion of piston；The pump housing 113 generates upward quick release
Power, water inlet valve block 5 are closed by thrust and by water inlet 106, due to the effect by upwards thrust, are discharged valve block 10 and are worked
Open water outlet 107, gap high speed of the water flow in the pump housing 113 between water outlet valve seat 112 and titting water outlet 8 is sprayed at this time
Out；Since the high speed rotation band movable eccentric wheel 16 of motor constantly rotates, to make the continuous downward fortune reciprocal upwards of piston 13
It is dynamic, so that the pump housing 113 is generated pulsed water flow constantly by sparge pipe high speed ejection.
According to the disclosure and teachings of the above specification, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula trip change and modification.Therefore, the invention is not limited to the specific embodiments disclosed and described above, to of the invention
Some modifications and changes should also be as falling into the scope of the claims of the present invention.In addition, although being used in this specification
Some specific terms, these terms are merely for convenience of description, does not limit the present invention in any way.
