The I-shaped hole 86 is communicated with the clamping groove 85, and a push column 87 is movably connected inside the I-shaped hole 86.

[0039] A slide groove is provided on the outer surface of the lower end of the flushing pipe 4 at a position corresponding to the rectangular groove, and a spring 2 88 and a sliding plate 89 are provided inside the slide groove, the sliding plate 89 is slidably connected to the slide groove, one end of the spring 2 88 is fixedly connected to the sliding plate 89, and the other end is fixedly connected to the slide groove, one end of the sliding plate 89 passes through the outside of the slide groove, and a clamping block 810 is fixedly connected to one side of the outer surface of the sliding plate 89 corresponding to the clamping groove 85, and the outer surface of the bottom end of the clamping block 810 is arc-shaped;

[0040] The sliding plate 89 is pushed by the rectangular groove to squeeze the spring 2 88 and continues to move downward. When the block 810 is completely aligned with the slot 85, the block 810 enters the interior of the slot 85 under the action of the spring 2 88, and the push column 87 moves to the outside of the body 1 under the push of the block 810. When disassembling, press the two groups of push columns 87 at the same time, the block 810 is disengaged from the slot 85, and the flushing tube 4 is pulled out upward, which is very convenient.

[0041] The working process and principle of the present invention are as follows:

[0042] Step 1, insert the outer ring 83 at the bottom end of the flushing pipe 4 into the interior of the connecting pipe 81, the nozzle 5 is stuck in the interior of the rotating block 72, and the outer surface of the nozzle 5 is fitted with the rotating ring 74, and the sliding plate 89 corresponds to the rectangular groove. The sliding plate 89 is pushed by the rectangular groove to squeeze the spring 2 88 and continue to move downward. When the block 810 completely corresponds to the slot 85, the block 810 enters the interior of the slot 85 under the action of the spring 2 88, and the push column 87 moves to the outside of the body 1 under the push of the block 810. At this time, the sealing strip 84 is located inside the sealing groove to prevent the cleaning liquid from flowing out through the gap between the outer ring 83 and the water outlet. When disassembling, press the two sets of push columns 87 at the same time, the block 810 is separated from the slot 85, and the flushing pipe 4 is pulled out upward, which is very convenient;

[0044] Step 3: Before flushing, the user can selectively install the annular cleaning brush 92. When installing the annular cleaning brush 92, the tooth plate 1 93 is matched with the installation groove 94 one by one, and the tooth plate 1 93 is pushed toward the inside of the installation groove 94. The tooth plate 2 96 is meshed with the tooth plate 1 93 under the action of the spring 1 97, thereby ensuring the stability of the annular cleaning brush 92 during use and facilitating the replacement of the annular cleaning brush 92. When the tooth plate 1 93 enters the installation groove 94, the support ring 99 contacts the annular cleaning brush 92. As the depth of the tooth plate 1 93 entering the installation groove 94 increases, the support ring 99 causes the annular cleaning brush 92 to expand outward, thereby facilitating the user to adjust the expansion state of the annular cleaning brush 92 according to needs to meet the different needs of users.

[0045] Step 4. During the flushing process, the user can select different cleaning modes by controlling different panel buttons. When the mode of using the annular cleaning brush 92 and flushing at the same time is selected, the motor 75 drives the rotating ring 74 to drive the annular cleaning brush 92 to rotate, so that the user's tooth surface can be flushed with the cleaning liquid while the annular cleaning brush 92 can be used to rotate and brush the tooth surface, thereby increasing the cleaning intensity of the teeth and enhancing the cleaning effect of the body 1.
