Specifically, the first tube 211 is sleeved outside the second tube 212, so that a liquid suction channel with a certain width is formed between the outer wall of the second tube 212 and the inner wall of the first tube 211 for the liquid to be recovered to pass through; liquid outlet holes 2211, a liquid outlet groove 2212 and a first liquid outlet channel 2213 are respectively formed in the brush head body 221 of the first brush head 23 and the brush head body 221 of the second brush head 24, the liquid outlet pipe 12 is communicated with the liquid outlet groove 2212 of the first brush head 23 through one or more liquid outlet branch pipes 2121, and is communicated with the liquid outlet groove 2212 of the second brush head 24 through one end, far away from the main machine part 10, of the second pipe body 212, when the liquid outlet pipe 12 conveys liquid to the first brush head 23 and the second brush head 24 through the second pipe body 212, the first brush head 23 and the second brush head 24 can synchronously rotate around the support shaft 21 in the same direction or in different directions under the driving of the liquid sprayed from the liquid outlet holes 2211, so that the executing part 20 can simultaneously wash and scrub the front side and the back side of teeth through the rotation of the first brush head 23 and the second brush head 24, and the tooth cleaning efficiency and effect are improved.

Optionally, referring to fig. 3 and 7, as an embodiment of the portable tooth flushing device provided by the present application, bearings 25 are respectively disposed at a connection portion of the first brush head 23 and the first tube 211 and a connection portion of the second brush head 24 and the first tube 211. Specifically, two bearings 25 are respectively sleeved on two end portions of the first pipe body 211, mounting holes are respectively formed in the middle of the first brush head 23 and the middle of the second brush head 24, and the mounting holes of the first brush head 23 and the mounting holes of the second brush head 24 are respectively fixedly connected with outer rings of the bearings 25. Therefore, the friction between the first brush head 23 and the first pipe body 211 and between the second brush head 24 and the first pipe body 211 can be reduced through the bearing 25, the mutual abrasion is reduced, the smoothness of the rotation of the first brush head 23 and the second brush head 24 around the first pipe body 211 is favorably improved, and the service life of the executing part 20 is favorably prolonged.

Optionally, referring to fig. 2, as an embodiment of the portable tooth rinsing device provided in the present application, the liquid storage tank 11 is detachably connected to the inside of the main machine portion 10. Specifically, the liquid storage tank 11 may be installed in a casing or a cover of the main machine part 10 alone, or may be integrally formed with the casing or the cover of the main machine part 10, and a liquid injection port is provided in the liquid storage tank 11, through which clear water or cleaning liquid may be added to the liquid storage tank 11.

Optionally, referring to fig. 1 and fig. 2, as a specific embodiment of the portable tooth rinsing device provided in the present application, the portable tooth rinsing device 1 further includes a control portion 30, the control portion 30 includes a circuit board 31, a control key 32 and an indicator light 33, wherein the circuit board 31 is disposed in the main unit portion 10 and is electrically connected to the first water pump 14 and the second water pump 15; the control keys 32 and the indicator lights 33 are respectively provided on the circuit board 31 and exposed on the outer surface of the main unit portion 10. Specifically, the circuit board 31 may be connected to a built-in portable power source, or may be externally connected to a power adapter, the control circuit of the circuit board 31 may control the first water pump 14 and the second water pump 15 to operate according to a program set when leaving a factory, the control key 32 may trigger the circuit board 31 to send an instruction to the first water pump 14 and the second water pump 15, and the indicator light 33 may enable a user to more intuitively know the operating conditions of the first water pump 14 and the second water pump 15.
