Referring to fig. 1 to 14, the specific working principle of the tooth-rinsing device provided by the invention is as follows:
the motor drives the eccentric wheel 16 to rotate at a high speed, the high-speed rotation of the eccentric wheel 16 drives the connecting rod 14 and the piston 13 to move downwards and rapidly, the piston 13 moves downwards and rapidly to enable the valve pump body 113 to generate suction force, the water outlet valve plate 10 moves downwards under the suction force of the pump, the water outlet 107 is in a closed state, and due to the suction force of the pump body 113, the water inlet valve plate 5 moves rightwards at the moment, the water inlet 106 is opened, and water flow in the water tank is sucked into the pump body 113 at a high speed through the water inlet groove 1111 and the water inlet guide surface 1112 at the moment; when the eccentric wheel 16 rotates at a high speed to drive the connecting rod 14 and the piston 13 to move upwards rapidly; the pump body 113 generates upward rapid pushing force, the water inlet 106 is closed under the action of pushing force of the water inlet valve plate 5, the water outlet 107 is opened due to the operation of the water outlet valve plate 10 under the action of upward pushing force, and at the moment, water flow in the pump body 113 is sprayed out at high speed along a gap between the water outlet valve seat 112 and the water outlet pipe joint 8; the high-speed rotation of the motor drives the eccentric wheel 16 to rotate continuously, so that the piston 13 reciprocates downwards and upwards continuously, and the pump body 113 generates pulse water flow which is sprayed out of the spray pipe at high speed continuously.
Variations and modifications to the above would be obvious to persons of ordinary skill in the art, in light of the foregoing description and the teachings. Therefore, the invention is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the invention should be also included in the scope of the claims of the invention. In addition, although specific terms are used in the present specification, these terms are for convenience of description only and do not limit the present invention in any way.
