The housing contains a valve body, a piston assembly, and a pressing assembly. In use, the pressing assembly can be continuously pressed down by adjusting the button assembly, thereby pushing the piston assembly to separate from the valve body, allowing the washing liquid to enter the valve body and then be sprayed out from the nozzle. Alternatively, the spray button of the button assembly can be placed above the pressing assembly, and pressing the spray button will move the pressing assembly downward, causing the pressing assembly to push the piston assembly to separate from the valve body.

[0050] In this embodiment of the invention, the nozzle structure includes a mounting component 3 and a nozzle 2. One end of the housing 1 is detachably connected to the nozzle 2 via the mounting component 3. The housing 1 contains a valve body 5, a piston assembly 6, and a pressing assembly 8. In use, the pressing assembly 8 can be continuously pressed down by adjusting the button assembly 4, thereby pushing the piston assembly 6 to separate from the valve body 5, so that the washing liquid enters the valve body 5 and is sprayed out from the nozzle 2. Alternatively, the spray button 42 of the button assembly 4 can be placed above the pressing assembly 8, and the pressing assembly 8 can be moved downward by pressing the spray button 42, thereby pushing the piston assembly 6 to separate from the valve body 5.

[0051] Compared with the prior art, the water flosser with a gear switching structure provided in this embodiment of the invention uses the button assembly 4 to continuously and intermittently push the pressing assembly 8 to move, and then the pressing assembly 8 drives the piston assembly 6 to separate from the valve body 5 to connect the channel through which the cleaning liquid can be sprayed from the nozzle 2, thereby realizing the function of quickly switching between water output and stop states during the water flossing process.

[0052] In an optional implementation of this embodiment, refer to Figure 3 or Figure 4 The valve body 5 has a liquid outlet chamber 51, a receiving chamber 52, and a piston chamber 53, which are connected in sequence.

[0060] Furthermore, referring to Figure 2 or Figure 3The pressing assembly 8 includes a pressing member 81 and a second elastic member 82. One end of the pressing member 81 is connected to the second elastic member 82, and the other end is connected to the button assembly 4. The pressing member 81 is provided with a protrusion 811, which is used to push the piston body 61 to move in the first direction when the pressing member 81 moves in the second direction, so that the first sealing ring 63 is disengaged from the cavity wall of the piston cavity 53.

[0061] Specifically: the bottom end of the pressing member 81 is connected to the second elastic member 82, and the top end of the pressing member 81 abuts against the button assembly 4. The second elastic member 82 is preferably a spring. The side wall of the pressing member 81 is provided with a protrusion 811, which is close to the end of the piston body 61. When the pressing member 81 is pushed down, the protrusion 811 is squeezed against the piston body 61, thereby pushing the piston body 61 to move towards the inner liner assembly 9.

[0066] Furthermore, referring to Figure 3 The gear key 41 is provided with a top block 411, which is used to press down the lower pressure member 81 when the gear key 41 is in the first position.

[0067] Specifically: The top block 411 is located at the bottom of the gear key 41, and when the gear key 41 is in the first position, the top block 411 abuts against the lower pressure member 81 so that the lower pressure member 81 pushes the piston assembly 6 to move. At this time, the first sealing ring 63 separates from the cavity wall of the piston cavity 53, and the washing liquid enters the nozzle 2 through the liquid outlet cavity 51.

[0068] In an optional implementation of this embodiment, refer to Figure 3 The water flosser with a gear switching structure also includes a sealing member 7, which is connected to the accommodating cavity 52. ​​The sealing member 7 has a fixing groove for connecting to the end of the second elastic member 82 away from the pressing member 81.
