[0019] The adjusting mechanism includes a rotating wheel 10, a rotating shaft 11, a threaded rod 12, a threaded sleeve 13, a transmission rack 14, a transmission gear 15, a transmission rod 16 and a limiting structure. The rotating wheel 10 is installed on one side of the installation cavity 9, and the rotating shaft 11 is installed inside the installation cavity 9. One end of the rotating wheel 10 is connected to one end of the rotating shaft 11, and the other end of the rotating shaft 11 is installed with a threaded rod 12. The outer wall of the threaded rod 12 is provided with a threaded sleeve 13. The top of the threaded sleeve 13 is installed with a transmission rack 14, and the transmission gear 15 is meshed above the transmission rack 14. The top of the transmission gear 15 is installed with a transmission rod 16, and the top of the transmission rod 16 extends To the outside of the mounting cavity 9, the top end of the transmission rod 16 is connected to the bottom end of the movable plate 7. When in use, the rotating wheel 10 is rotated, and the rotating shaft 11 is used to drive the threaded rod 12 to rotate. Therefore, under the limitation of the limiting rod 18 and the limiting sleeve 19, the threaded rod 12 is used to drive the threaded sleeve 13 to move, and then the transmission rack 14 is driven to move, so the transmission gear 15 is driven to rotate, and then under the limitation of the limiting rail 17, the transmission gear 15 is used to drive the transmission rod 16 to move, and then the nozzle 8 is driven to move, and the angle of the nozzle 8 is adjusted, so as to perform multi-directional washing of the oral cavity without opening the mouth very wide, thereby greatly improving the practicality of the device when in use.

[0020] The limiting structure includes a limiting rail 17, a limiting rod 18 and a limiting sleeve 19. The limiting rail 17 is installed at the top of the installation cavity 9. A movable block is arranged inside the limiting rail 17. One end of the movable block is connected to one end of the transmission rod 16. The limiting rod 18 is installed at the bottom of the installation cavity 9. The outer wall of the limiting rod 18 is provided with a limiting sleeve 19. The top of the limiting sleeve 19 is connected to the bottom end of the threaded sleeve 13. The cross section of the limiting rod 18 is smaller than the cross section of the limiting sleeve 19. The limiting rod 18 and the limiting sleeve 19 form a sliding structure, the limiting rail 17 is designed in an arc shape, and the center of the limiting rail 17 is on the same straight line as the center of the transmission gear 15. When in use, the limiting rail 17 can be used to limit the transmission rod 16 when it moves, so that the transmission rod 16 is more stable when it moves. The limiting rod 18 and the limiting sleeve 19 cooperate with each other to limit the threaded sleeve 13 when it moves, so that the threaded sleeve 13 is more stable when it moves.

[0021] The replacement mechanism includes a limit plate 20, a rotating sleeve 22, an internal thread 23 and an external thread 24. The limit plate 20 is installed on the outer wall of the nozzle 8. The bottom end of the nozzle 8 extends to the inside of the mounting plate 6. The mounting plate 6 and the outer side of the limit plate 20 are provided with a rotating sleeve 22. The inner wall of the rotating sleeve 22 is provided with an internal thread 23. The inner wall of the mounting plate 6 is provided with an external thread 24. The internal thread 23 and the external thread 24 form a threaded connection. When in use, the rotating sleeve 22 is rotated. Since the internal thread 23 and the external thread 24 are threadedly connected, The rotating sleeve 22 moves on the outer wall of the mounting plate 6. At this time, the nozzle 8 can be taken out from the inside of the mounting plate 6, and then a new nozzle 8 is taken out, and the rotating sleeve 22 is set on the outside of the nozzle 8, and one end of the nozzle 8 is placed into the inside of the mounting plate 6. Then, the rotating sleeve 22 is rotated in the opposite direction to drive the nozzle 8 to move downward, and the sealing gasket 21 is used to seal the mounting plate 6 and the nozzle 8 to complete the convenient replacement of the nozzle 8. The nozzle 8 can be conveniently disassembled and installed, making it more convenient and quick to replace the nozzle 8, thereby greatly improving the convenience of the device when in use.

[0022] A sealing gasket 21 is disposed inside the mounting plate 6 , and the sealing gasket 21 can seal the mounting plate 6 and the nozzle 8 , so that the nozzle 8 has a better effect and is less likely to leak when in use.

[0023] Working principle: the user first puts water into the water storage barrel 1, then holds the handle 5 and starts the booster pump 3, draws the water inside the water storage barrel 1 into the inside of the nozzle 8, sprays it out with the nozzle 8, inserts the nozzle 8 into the mouth, and uses the water flow to rinse and clean the mouth. At this time, the user rotates the wheel 10, and uses the rotating shaft 11 to drive the threaded rod 12 to rotate. Therefore, under the limit of the limit rod 18 and the limit sleeve 19, the threaded rod 12 drives the threaded sleeve 13 to move, and then drives the transmission rack 14 to move, so that the transmission gear 15 is driven to rotate, and then under the limit of the limit rail 17, the transmission gear 15 drives the transmission rod 16 Move it, thereby driving the nozzle 8 to move, adjust the angle of the nozzle 8, and then perform multi-directional flushing of the oral cavity. When the nozzle 8 needs to be replaced, rotate the rotating sleeve 22. Due to the threaded connection between the internal thread 23 and the external thread 24, the rotating sleeve 22 moves on the outer wall of the mounting plate 6. At this time, the nozzle 8 can be taken out from the inside of the mounting plate 6, and then take out the new nozzle 8, and put the rotating sleeve 22 on the outside of the nozzle 8, place one end of the nozzle 8 into the inside of the mounting plate 6, and then rotate the rotating sleeve 22 in the opposite direction to drive the nozzle 8 to move downward, and use the sealing gasket 21 to seal the mounting plate 6 and the nozzle 8 to complete the convenient replacement of the nozzle 8.
