As shown in fig. 1 to 3, the present invention provides a tooth washing device, which comprises a housing 1, wherein a magnetic driving structure is arranged inside the housing 1, the magnetic driving structure is connected with a piston assembly, the piston assembly is respectively provided with a water inlet 11 and a water outlet 81, and the magnetic driving structure drives the piston assembly to suck water from the water inlet 11 or spray water from the water outlet 81.

The magnetic drive structure includes solenoid valve coil 2, and solenoid valve coil 2 is formed with the holding hole, and the holding hole sets up

iron core

3, and 2 electricity of solenoid valve coil are connected with the controller to 2 circular telegrams of controller control solenoid valve coil, solenoid valve coil 2 after the circular telegram make the terminal surface of iron core 3 produce different magnetic poles, and then produce the phenomenon of electricity magnetism, provide drive power for piston assembly.

Piston assembly includes piston body 5, and piston body 5's bottom surface is provided with the recess, and permanent magnet 4 has been put to the recess inside, and

permanent magnet

4 and 3 looks effects of iron core, and when

permanent magnet

4 and 3 magnetic poles of iron core the same, like polarity magnetic pole repel each other, and 3 drives permanent magnet 4 of iron core and keeps away from 3 movements of iron core and then drive piston assembly and keep away from 3 direction movements of iron core. When the magnetic poles of the permanent magnet 4 and the iron core 3 are different, the opposite poles attract each other, and the iron core 3 drives the permanent magnet 4 to move close to the iron core 3 so as to drive the piston assembly to move close to the iron core 3.

The outside cover of piston body 5 is equipped with piston cylinder 8, and

piston body

5 and 8 sealing connection of piston cylinder to realize the sealed in the piston cylinder 8.

The top of the piston body 5 is connected with a sealing block 6, and the sealing block 6 is abutted against the side wall of the piston cylinder 8, so that the piston body 5 is sealed in the piston cylinder 8.

The bottom surface of seal block 6 is provided with the cell body with 5 tip matched with of piston body to insert the cell body of seal block 6 with the tip of piston body 5, closely cooperate 5 tip of piston body and seal block 6, realize
