[0023] like Figures 1 to 8 As shown, in the first embodiment, a diaphragm sealing structure of a water flosser comprises a movement housing 10, an elastic diaphragm 20, a water outlet adapter 30 and a driving member 40 for driving the elastic diaphragm 20 to deform; the top of the movement housing 10 is fixedly connected to the water outlet adapter 30, the water outlet adapter 30 is provided with a diaphragm cavity 31, a water inlet channel 32 and a water outlet channel 33, a one-way water outlet valve 34 is provided between the water outlet channel 33 and the diaphragm cavity 31, the water inlet channel 32 and the diaphragm cavity 31 are connected to each other, and the one-way water outlet valve 34 is provided between the water outlet channel 33 and the diaphragm cavity 31.

The elastic diaphragm 20 includes a diaphragm body 21, a deformation portion 22 and a buckle portion 23. One end of the deformation portion 22 is connected to the diaphragm body 21, and the other end is connected to the buckle portion 23. The buckle portion 23 is sealed and clamped in the card slot 36. When the driving member 40 drives the elastic diaphragm 20, the elastic diaphragm 20 can be driven to deform repeatedly to cause the pressure in the diaphragm cavity 31 to change.

[0024] like Figures 1 to 8 As shown, the driving member 40 is located in the movement housing 10 and is used to drive the elastic diaphragm 20 to reciprocate.

[0025] like Figures 1 to 8As shown, the elastic diaphragm 20 has a certain elasticity, the buckle portion 23 is tightly clamped in the clamping groove 36 , and the buckle portion 23 is in close contact with the clamping groove 36 .

[0026] like Figures 1 to 8 As shown, the diaphragm cavity 31 is separated from the movement housing 10 by the elastic diaphragm 20, and the driving member 40 drives the elastic diaphragm 20 to reciprocate. When the driving member 40 drives the diaphragm body 21 and the deformation portion 22 to deform or move upward, the one-way water inlet valve 35 is closed, the air pressure in the diaphragm cavity 31 increases, the one-way water outlet valve 34 is opened, and the liquid in the diaphragm cavity 31 is ejected from the one-way water outlet valve 34.

[0027] like Figures 1 to 8 As shown, when the driving member 40 drives the diaphragm body 21 and the deformation portion 22 to deform or move downward, suction is generated in the diaphragm cavity 31, the one-way water outlet valve 34 is closed, the one-way water inlet valve 35 is opened, and the water inlet channel 32 injects liquid into the diaphragm cavity 31.

[0028] like Figures 1 to 8 As shown, since the buckle portion 23 and the slot 36 are sealed and clamped, the buckle portion 23 and the slot 36 always remain sealed and clamped during the repeated deformation of the diaphragm body 21 and the deformation portion 22, and the sealing effect between the elastic diaphragm 20 and the inner wall of the diaphragm cavity 31 is good, preventing air leakage in the diaphragm cavity 31.

[0029] like Figures 1 to 8 As shown, the diaphragm sealing structure of the water flosser also includes an annular fixing seat 50, and the inner edge of the upper surface of the annular fixing seat 50 is provided with an annular baffle 51, and the annular fixing seat 50 is fixed to the inner wall of the diaphragm cavity 31, and the inner wall of the diaphragm cavity 31, the annular fixing seat 50 and the annular baffle 51 form a lower annular groove 52, and the inner wall of the diaphragm cavity 31 is provided with an upper annular groove 37, and there is a gap between the lower annular groove 52 and the upper annular groove 37, and the lower annular groove 52 and the upper annular groove 37 form a clamping groove 36, and the buckle portion 23 includes an upper protrusion 231 that is sealed and clamped in the upper annular groove 37, and a lower protrusion 232 that is sealed and clamped in the lower annular groove 52.

[0030] like Figures 1 to 8 As shown, the upper protrusion 231 is sealed and clamped in the upper annular groove 37, and the lower protrusion 232 is sealed and clamped in the lower annular groove 52, with double sealing and good sealing effect; during the repeated deformation process of the diaphragm body 21 and the deformation part 22, the buckle part 23 and the clamping groove 36 always remain sealed and clamped, and the sealing effect between the elastic diaphragm 20 and the inner wall of the diaphragm cavity 31 is good. The annular fixing seat 50 is fixed on the inner wall of the diaphragm cavity 31, which is convenient for the installation and fixation of the elastic diaphragm 20.

[0031] like Figures 1 to 8As shown, the driving member 40 includes a driving motor 41, a main shaft gear 42, a toothed disc 43 meshing with the main shaft gear 42, an eccentric wheel 44 and a driving rod 45. The upper end of the driving rod 45 is connected to the diaphragm body 21, and the lower end is connected to the eccentric wheel 44. The eccentric wheel 44 is fixed to the disk surface of the toothed disc 43. The eccentric wheel 44 and the toothed disc 43 are rotatably connected to the movement housing 10 via a rotating shaft 46 respectively. The driving motor 41 drives the toothed disc 43 to rotate via the main shaft gear 42.

[0032] like Figures 1 to 8 As shown, the driving motor 41 rotates to drive the main shaft gear 42 to rotate, and the main shaft gear 42 drives the toothed plate 43 and the eccentric wheel 44 to rotate. When the eccentric wheel 44 rotates, it drives the driving rod 45 to move up and down, and the driving rod 45 moves up and down to drive the elastic diaphragm 20 to reciprocate.

[0034] like Figures 1 to 8 As shown, when the driving rod 45 moves upward, the fixed head 451 pushes the diaphragm body 21 to deform upward, and when the driving rod 45 moves downward, the fixed head 451 pulls the diaphragm body 21 to deform downward.

[0035] like Figures 1 to 8 As shown, the upper end of the driving rod 45 is provided with a driving sheet 452, and the driving sheet 452 is located below the fixing head 451 and close to the lower surface of the diaphragm body 21.
