And the driving mechanism 22 is arranged at the center of the plurality of water squeezing mechanisms 21 and sequentially squeezes the plurality of water squeezing mechanisms 21 during operation so as to drive the water squeezing mechanisms 21 to circularly perform water absorption and water squeezing actions. And a check valve assembly 23 provided on the wringing mechanism 21, the check valve assembly 23 preventing water in the wringing mechanism 21 from flowing into the water storage chamber a and preventing water in the nozzle 11 from flowing back into the wringing mechanism 21. And a guide mechanism 24 provided in the water squeezing mechanism 21 for guiding the water in the water storage chamber a into the water squeezing mechanism 21 and guiding the water in the water squeezing mechanism 21 into the nozzle 11. The drive mechanism 22 includes: a motor 221. And a cam 222 fixed to a transmission shaft of the motor 221 and abutting against the wringing mechanism 21, wherein one side surface of the cam 222 abutting against the wringing mechanism 21 is provided with an inclined surface.

Based on the above structure, the wringing mechanisms 21 are provided as the first wringing mechanism 21, the second wringing mechanism 21, and the third wringing mechanism 21, and it is assumed that in the initial state, the cam 222 presses the first wringing mechanism 21. When the motor 221 rotates, the cam 222 is synchronously driven to rotate, so that the cam 222 loosens the squeezing action on the first wringing mechanism 21, rotates to the second wringing mechanism 21 to squeeze the second wringing mechanism 21, squeezes water in the second wringing mechanism 21 into the guide mechanism 24, guides the water into the nozzle 11 by the guide mechanism 24, and then sprays the water out of the nozzle 11 to clean the oral cavity and the teeth; since the water inside the first wringing mechanism 21 is squeezed out after being squeezed by the cam 222, the water can be sucked from the water storage cavity a; since the motor 221 drives the cam 222 to rotate, when the cam 222 returns to the first wringing mechanism 21, the first wringing mechanism 21 is squeezed again, water in the first wringing mechanism 21 is squeezed into the guide mechanism 24, and the water is guided into the nozzle 11 by the guide mechanism 24. Based on this, because the plurality of water squeezing mechanisms 21 are arranged circumferentially, the cam 222 can always squeeze one of the water squeezing mechanisms 21 in the rotating process, so that water can be continuously sprayed out from the nozzle 11 in the rotating process of the cam 222, and the stability and continuity of the tooth flushing device in the using process are ensured; meanwhile, the cam 222 loosens the squeezing action on the previous squeezing mechanism 21 when squeezing the next squeezing mechanism 21, so that the previous squeezing mechanism 21 can suck water in the water storage cavity a, thereby ensuring that enough water is squeezed out of each squeezing mechanism 21. Meanwhile, the cam 222 sequentially presses the wringing mechanisms 21, so that the plurality of wringing mechanisms 21 can be performed in sequence without mutual interference in the water absorbing and wringing processes.

To prevent the cam 222 from being damaged, the driving mechanism 22 of the present embodiment preferably further includes: a base 223 mounted on the motor 221, the base 223 for receiving the cam 222.

Based on the above structure, the motor 221 is started to drive the cam 222 to rotate, and the rotating shaft 211 can be driven to rotate because the rotating shaft 211 is abutted against one side surface of the cam 222 close to the rotating shaft 211. Since one side surface of the cam 222 close to the rotating shaft 211 is provided with an inclined surface, the rotating shaft 211 has a characteristic that one side is higher than the other two sides in the rotating process. Meanwhile, since one end of the bulge 212 is assembled on the rotating shaft 211, the higher end of the rotating shaft 211 can press the bulge 212 during the rotation of the rotating shaft 211, and can extrude the water in the bulge 212 into the nozzle 11. Therefore, the rotating shaft 211 is controlled to rotate by the motor 221 so as to extrude the bulge 212 to control the bulge 212 to absorb and squeeze water, and the structures such as pistons, gears and the like are not adopted in the water absorbing and squeezing process, so that noise generated by friction among all parts can not occur in the transmission process, and the water absorbing and squeezing device is more comfortable in use.

To ensure the stability of the bulge 212, the wringing mechanism 21 further includes: the middle frame 213 is installed on the base 223, a second installation hole e is formed in the middle frame 213, and one end of the bulge 212, which is close to the second installation hole e, is assembled in the second installation hole e. Based on the above structure, by providing the middle frame 213 and the rotation shaft 211, both ends of the swelling 212 are fitted in the first mounting hole c and the second mounting hole e, respectively. Because the middle frame 213 and the rotating shaft 211 are both fixedly arranged on the base 223, the bulge 212 can be fixed on the base 223, and the stability of the bulge 212 in the water absorbing and squeezing processes can be ensured.

And the silica gel piston 232 is assembled in the second water inlet f and used for blocking the second water inlet f and protrudes to one side close to the bulge 212. And a silica gel plug 233 which is assembled in the mounting groove g, is used for blocking the water outlet h and protrudes to one side far away from the bulge 212.

To ensure the use effect of the guide mechanism 24, as a preferable solution, the guide mechanism 24 of the present embodiment includes: install connector 241 on middle cover plate 231, connector 241 includes: a water inlet pipe 2411 with one end communicated with the second water inlet f and the other end communicated with the water storage cavity a, and a water outlet pipe 2412 with one end communicated with the water outlet h and the other end communicated with the nozzle 11.

To ensure the sealing effect of the guide mechanism 24, as a preferable solution, the guide mechanism 24 of the present embodiment further includes: and the silica gel pad 242 is sleeved on the connector 241 and is positioned between the connector 241 and the middle cover plate 231.

The working principle is as follows:

and (3) water absorption process: firstly, water is filled into the water storage cavity a through the water filling port b, and then the water filling port b is closed. Water enters the water pump 20 from the water storage cavity a through the water inlet pipe 2411; then, since the second water inlet f is provided with the silica gel piston 232 (which is a one-way valve structure, i.e., water can enter the bulge 212 and the water in the bulge 212 can be placed to flow out from the second water inlet f), the water sequentially enters the bulge 212 through the second water inlet f and the first water inlet d.

A water squeezing process: the motor 221 is started, and the cam 222 is rotated by the motor 221. The higher end of the cam 222 will always press against one of the bulges 212 during rotation. After the bulge 212 is pressed, the water in the bulge 212 flows out from the second water inlet f. Because the second water inlet f is provided with the silica gel piston 232, water flow cannot enter the water storage cavity a from the second water inlet f and flows to the water outlet h; because the silica gel plug 233 (which is a one-way valve structure, i.e., water in the bulge 212 can flow into the water outlet pipe 2412 from the water outlet h and can prevent the water in the water outlet pipe 2412 from flowing back into the bulge 212) is arranged at the water outlet h, water flow can enter the water outlet pipe 2412 from the water outlet h and enter the nozzle 11 from the water outlet pipe 2412; and finally ejected from the nozzle 11 to wash the oral cavity and teeth.
