[0037] Please see below. Figures 1-5 The present invention provides a stepless adjustment component 10, which is applied in a water flosser 20, and specifically includes:

[0038] The control key 11 has a recessed mounting cavity 111, and the mounting cavity 111 has a mounting seat 112 protruding from the bottom surface in the middle.

[0039] The adjusting shaft 12 is fixedly installed in the mounting base 112 and extends out of the mounting base 112 along the opening direction of the mounting cavity 111;

[0040] Mounting bracket 13 is installed inside mounting cavity 111 and sleeved on mounting base 112;

[0041] Potentiometer 14 is installed in mounting bracket 13 and sleeved on adjusting shaft 12;

[0042] The PCB control board 15 is fixed on the top of the mounting bracket 13 and covers the potentiometer 14 and is electrically connected to the potentiometer 14.

[0043] The control key 11 adjusts the parameters of the potentiometer 14 by rotating or pressing the adjustment shaft 12.

[0044] In this embodiment, the adjustment shaft 12, potentiometer 14, and PCB control motherboard 15 are mounted on the control key 11 by setting the mounting bracket 13 and mounting base 112. By tightly integrating each component into an independent assembly unit, the adjustment function is integrated into one unit. Then, the independent stepless adjustment component 10 is installed on the water flosser 20. While realizing stepless adjustment of the water flosser 20, the structural design is simplified, the installation efficiency and structural stability of the water flosser 20 are improved, thereby reducing production costs and enhancing the user experience.

[0045] Potentiometer 14 is a resistive element whose parameters can be adjusted according to a certain change law. In this embodiment, by rotating the control key 11, the adjustment shaft 12 is driven to rotate. The adjustment shaft 12 rotates back and forth 360° to drive the potentiometer 14 to issue commands to adjust the parameters of the potentiometer 14, such as adjusting the resistance value or voltage duty cycle of the potentiometer 14, etc. (the specific adjustment depends on the type of potentiometer 14). This enables stepless adjustment of the water flow intensity of the oral irrigator 20. Users can accurately control the water flow according to actual needs, improving the comfort of use and the oral irrigating effect.

[0046] For example, clockwise rotation can be set to decrease resistance and increase water flow, while counterclockwise rotation can increase resistance and decrease water flow, making operation simple and adaptable to different oral care needs. In addition, the power-on and power-off states of potentiometer 14 can be controlled by pressing the control button 11, thereby turning the oral irrigator 20 on or off, achieving a dual-function operation with one button, simplifying the operation process and improving the user experience.

[0047] In specific application scenarios, the selection of potentiometer 14 can be flexibly adjusted according to the model of the water flosser 20 and user needs to ensure the best adjustment effect.

[0048] In one embodiment, the adjustment shaft 12 includes a mounting shaft 121 and a control shaft 122 extending out of the mounting shaft 121. The mounting shaft 121 is snapped into the mounting base 112, and the control shaft 122 protrudes out of the mounting base 112.

[0049] Potentiometer 14 is fitted onto control shaft 122.

[0050] In this embodiment, the adjustment shaft 12 ensures rotational stability through the tight fit between the mounting shaft 121 and the mounting base 112, while the extended design of the control shaft 122 facilitates the installation of the potentiometer 14, thereby improving the overall compactness and installation efficiency of the assembly.

[0051] In other application scenarios, other mating methods can also be used to fix the mounting shaft 121 into the mounting base 112, such as by threaded connection or adhesive bonding, etc.

[0052] Combination Figure 6 and Figure 7 In one embodiment, the mounting bracket 13 is hollowly provided with a first mounting portion 131 and a second mounting portion 132;

[0053] The mounting bracket 13 is sleeved onto the mounting base 112 via the first mounting part 131, and the potentiometer 14 is installed in the second mounting part 132.

[0054] In this embodiment, by designing the mounting bracket 13 as a hollow structure, the first mounting part 131 is used to achieve a stable connection between the mounting bracket 13 and the mounting base 112, and the second mounting part 132 is used to achieve precise positioning and fixation of the potentiometer 14, ensuring that the potentiometer 14 is stable and reliable during adjustment.

[0055] In one embodiment, the stepless adjustment assembly 10 further includes an O-ring 16 disposed between the mounting base 112 and the mounting bracket 13, the O-ring 16 being sleeved around the outer edge of the mounting base 112.

[0056] In this embodiment, by providing an O-ring 16 between the mounting base 112 and the mounting bracket 13, the sealing is enhanced, and the pressing of the control key 11 is also buffered, thereby improving the durability and safety of the stepless adjustment component 10 and extending the service life of the equipment.

[0057] In other embodiments, an O-ring 16 may also be provided on the periphery of the mounting bracket 13, thereby further improving the durability and safety of the stepless adjustment component 10.

[0058] In one embodiment, a snap-fit ​​portion 113 protrudes from the inner wall of the control key 11, and a snap-fit ​​plate 133 is provided on the side of the mounting bracket 13. The snap-fit ​​plate 133 is provided with a mounting through groove 134 that matches the snap-fit ​​portion 113.

[0059] In this embodiment, by engaging the snap-fit ​​portion 113 provided on the inner sidewall of the control key 11 with the snap-fit ​​plate 133 on the side of the mounting bracket 13, a stable connection between the control key 11 and the mounting bracket 13 is achieved, ensuring no shaking during operation and guaranteeing the user's experience.

[0060] Specifically, when installing the mounting bracket 13 into the mounting cavity 111 of the control key 11, the mounting slot 134 can be aligned with and pass through the snap-fit ​​part 113, thereby placing the snap-fit ​​plate 133 below the snap-fit ​​part 113. Then, by rotating the mounting bracket 13, the mounting slot 134 and the snap-fit ​​part 113 are misaligned, thereby limiting the snap-fit ​​plate 133 using the snap-fit ​​part 113. This achieves a tight fixation between the mounting bracket 13 and the control key 11, ensuring the stability of the adjustment process. Conversely, when it is necessary to disassemble the mounting bracket 13, first rotate the mounting bracket 13 until the mounting slot 134 and the snap-fit ​​part 113 are aligned, and then pull the mounting bracket 13 upwards to easily remove the mounting bracket 13 from the control key 11. The whole process is simple and quick, greatly improving the maintenance efficiency of the equipment.

[0061] In specific application scenarios, the number and distribution of the snap-fit ​​parts 113 can be adjusted according to actual needs to ensure a more secure connection between the mounting bracket 13 and the control key 11. For example, three snap-fit ​​parts 113 can be arranged in a circumferential array on the inner side wall of the control key 11. Of course, the number and position of the mounting slots 134 can also be adjusted according to actual conditions to achieve the best balance between fixing effect and installation convenience.

[0062] In one embodiment, the outer wall of the control key 11 is designed with an anti-slip textured surface. This anti-slip textured surface effectively increases the friction between the user's hand and the control key 11 during operation, thereby improving operational sensitivity and stability, and preventing misoperation due to sweaty or slippery hands, further enhancing the user experience.

[0063] In one embodiment, the stepless adjustment assembly 10 further includes a spring 17, with its two ends abutting against the control key 11 and the mounting bracket 13, respectively.

[0064] In this embodiment, by setting the two ends of the spring 17 to abut against the control key 11 and the mounting bracket 13 respectively, it can provide appropriate elastic feedback when the control key 11 is pressed, so that the control key 11 can effectively rebound after being pressed for the next pressing operation, ensuring the sensitivity and durability of the control key 11. Specifically, a slot for the spring 17 can be provided at the bottom of the mounting bracket 13 for mounting the spring 17.

[0065] In one embodiment, the top of the mounting bracket 13 is provided with screw holes, and the PCB control motherboard 15 is installed and fixed to the top of the mounting bracket 13 by screws engaging with the screw holes.

[0066] In this embodiment, the PCB control motherboard 15 is tightly fixed to the screw holes on the top of the mounting bracket 13 by screws to ensure circuit stability, prevent poor contact caused by vibration, and ensure the operational stability and safety of the equipment.

[0067] This utility model embodiment also provides a water flosser 20, including the stepless adjustment component 10 as described above.

[0068] In one embodiment, the water flosser 20 is provided with a body PCB motherboard, and the body PCB motherboard and the PCB control motherboard 15 are electrically connected through an FPC flexible board.

[0069] This utility model embodiment integrates the components of the stepless adjustment assembly 10 into an independent assembly unit, and then connects the stepless adjustment assembly 10 to the main PCB board of the machine body through an FPC flexible board connection. This avoids the problem of the adjustment shaft 12 and potentiometer 14 being unable to be assembled due to misalignment, improves production efficiency, and facilitates later maintenance through modular design.

[0070] In a specific embodiment, the connection and fixation between the infinitely adjustable component 10 and the machine body can be achieved by setting corresponding fastening positions on the infinitely adjustable component 10 and the machine body.

[0071] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to in the method section. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.

[0072] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
