[0036] The existing water flossers do not allow users to intuitively understand the current adjustment level and water pressure when the water flosser is not turned on, which limits the user's precise control over water pressure adjustment and increases the uncertainty during use.

[0037] This utility model proposes a dental flosser.

[0038] Please see Figure 1 and Figure 5 In one embodiment of this utility model, the oral irrigator includes:

[0039] The outer casing 1 has an internal cavity, and the top of the outer casing 1 is provided with a spray assembly 11;

[0040] Water pump 2 is located inside the cavity and connected to the spray assembly 11, and is used to supply water to the spray assembly 11.

[0041] Adjustment mechanism 3 is rotatably located within the cavity;

[0042] The gear position indicator structure 4 includes a plurality of gear position display sections 41 disposed on the adjustment mechanism 3 and a gear position indicator line 42 disposed on the housing 1. Rotation of the adjustment mechanism 3 causes at least one of the plurality of gear position display sections 41 to be exposed on the housing 1 and aligned with the gear position indicator line 42; and

[0043] The water outlet control mechanism 5 is located inside the cavity and is connected to the regulating mechanism 3 and the water outlet pump 2. The regulating mechanism 3 adjusts the water pressure and water speed of the water outlet pump 2 by controlling the water outlet control mechanism 5.

[0044] The technical solution of this utility model, by setting a gear indicator structure 4, provides an intuitive gear display when the water flosser is off. Users can easily identify the current gear setting by checking the alignment of the gear display section 41 with the gear indicator line 42, providing visual feedback. The adjustment mechanism 3 has multiple gear display sections 41, allowing users to clearly know the current gear and corresponding water pressure when adjusting the water flosser while it is off, achieving accurate adjustment feedback. Furthermore, even if the user accidentally touches the adjustment mechanism 3, they can still accurately adjust to the desired gear while the water flosser is off, improving the user experience and solving the problem that existing water flossers can only be adjusted after the water flosser is turned on. In this solution, the adjustment mechanism 3 is connected to the water outlet adjustment mechanism 3. By rotating the adjustment mechanism 3, the water outlet control mechanism 5 can be controlled, thereby controlling the water pressure and speed supplied by the water pump 2 to the spray assembly 11.

[0045] Specifically, the gear indicator structure 4 includes multiple gear display sections 41 mounted on the adjustment mechanism 3 and a gear indicator line 42 mounted on the housing 1. For example, it could consist of three dotted marks of different colors and a line perpendicular to the housing 1. The gear display sections 41 could be marks of different colors or shapes (such as red, yellow, and blue), or multiple numerical labels (representing different water pressures and speeds). By rotating the adjustment mechanism 3, at least one of the gear display sections 41 is exposed on the housing 1 and aligned with the gear indicator line 42, allowing the user to visually see the current gear setting. The water outlet control mechanism 5 can be a solenoid valve or an electronic control module with a microprocessor, used to connect the adjustment mechanism 3 and the water pump 2. The adjustment mechanism 3 can be a knob with gears, whose rotation within the cavity controls the water outlet control mechanism 5. Optionally, the knob can also have an anti-slip texture, allowing the user to receive tactile feedback from the adjustment mechanism 3 when switching between different gears. Optionally, the stamping press 100 may also be equipped with a water tank 8, which can be installed inside the cavity or outside the cavity and snapped into the outer casing 1, as long as it is connected to the water pump 2 and can provide a water source for the water pump 2. Furthermore, a water suction pipe may also be provided inside the water tank 8, with one end of the water suction pipe extending to the bottom of the water tank 8 and the other end of the water suction pipe extending out of the water tank 8 and communicating with the water pump 2. In this way, even when the water volume in the water tank 8 is low, water can still be drawn out to supply the water pump 2.

[0046] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The housing 1 has a display port, with a gear indicator line 42 located at the edge of the display port. At least one gear display part 41 on the adjustment mechanism 3 is exposed in the display port. Among the multiple gear display parts 41, the gear display part 41 aligned with the gear indicator line 42 indicates the current gear. The housing 1 can be an injection-molded plastic shell with a mounting position for the injection assembly 11 on the top and a display port at an appropriate location. The display port can be circular or square, allowing the user to directly observe the gear indicator line 42 and the gear display part 41, intuitively identifying the current gear setting. Multiple gear display parts 41 can be set as needed, for example, 1-10 gears. Figure 1 The indicator shown indicates that the current gear is gear 1. The gear indicator line 42 is located at the edge of the display port and can be a line engraved or painted on the edge of the display port. Optionally, the gear indicator line 42 is set perpendicular to the edge of the display port.

[0047] In the embodiments of this utility model, please refer to Figure 3 The regulating mechanism 3 includes:

[0048] Adjusting bracket 31, fixedly installed inside the cavity, and

[0049] The toggle switch 32 is rotatably sleeved on the outer periphery of the adjusting bracket 31, and the outer periphery of the toggle switch 32 is provided with multiple gear display sections 41.

[0050] Specifically, the adjusting bracket 31 can be a metal or plastic structure fixed inside the cavity of the outer casing 1 to support the toggle switch 32. For example, it can be an L-shaped or T-shaped bracket made of stainless steel. The toggle switch 32 can be a circular or strip-shaped rotating wheel structure, fitted around the outer periphery of the adjusting bracket 31, allowing it to rotate freely. The gear display section 41 can be markings on the outer periphery of the toggle switch 32, such as dots or scales of different colors. For example, it can be five different colored dot markings, such as red, yellow, blue, green, and purple, representing different water pressure and water speed settings. The user adjusts the gear by rotating the toggle switch 32. The rotation of the toggle switch 32 is transmitted to the water outlet control mechanism 5 through the adjusting bracket 31, thereby changing the water pressure and water speed of the water pump 2.

[0051] In the embodiments of this utility model, please refer to Figure 4 The toggle switch 32 has a gear position area 321 and a locking area 322, which are independently arranged. Multiple gear position display sections 41 are located on the outer periphery of the gear position area 321. Multiple locking grooves 3221 are spaced apart on the side of the locking area 322 facing the adjustment bracket 31. The adjustment mechanism 3 also includes an elastic component 33, which is located on the adjustment bracket 31. By rotating the toggle switch 32 around the outer periphery of the adjustment bracket 31, the elastic component 33 abuts against any of the locking grooves 3221. The elastic component 33 can be a spring 332 or a rubber pin. When the toggle switch 32 is switching gears, the elastic component 33 will be compressed to a certain extent. When the gear is in position, the elastic component 33 presses against the locking groove 3221. The toggle switch 32 can be a circular disc structure. One side (gear area 321) has multiple gear display sections 41 of different colors or shapes, and the other side (locking area 322) has multiple locking grooves 3221. This allows a part of the toggle switch 32 to adjust the gear at the display port, while the locking grooves 3221 on the other part inside the cavity cooperate with the elastic component 33 to achieve locking, so that the toggle switch 32 can be positioned at a certain gear when no external force is applied, preventing accidental rotation.

[0052] In the embodiments of this utility model, please refer to Figure 3The adjusting bracket 31 has a mounting groove 311, and the elastic component 33 is located in the mounting groove 311. The elastic component 33 includes a locking rod 331 and a spring 332. One end of the spring 332 abuts against the bottom of the mounting groove 311, and the other end of the spring 332 is sleeved on the outer periphery of the locking rod 331. The end of the locking rod 331 away from the spring 332 abuts against the locking groove 3221. The mounting groove 311 is a groove opened on the adjusting bracket 31, which can be elongated or cylindrical, to accommodate the elastic component 33. The specific shape can be designed according to the shape of the elastic component 33. The locking rod 331 can be a small-diameter metal rod, and the spring 332 can be a compression spring. When the locking rod 331 is pushed into the locking groove 3221 under the action of the spring 332, it will make a crisp collision sound, giving the user auditory feedback and preventing the user from switching gears at once. The spring 332 can provide slight resistance to the locking rod 331 to prevent accidental contact by the user.

[0053] In the embodiments of this utility model, please refer to Figure 5 The regulating mechanism 3 also includes a control component 34, which is connected to the toggle switch 32. The water outlet control mechanism 5 includes a compression component 51 and a drive motor 52. The drive motor 52 is located inside the cavity and electrically connected to the control component 34. One end of the compression component 51 is connected to the drive motor 52, and the other end is movably located inside the water outlet pump 2. The control component 34 can be an electronic module with a circuit board and control buttons, for example, a small circuit board integrating a microcontroller and multiple buttons, used for electrical connection with the toggle switch 32. The control component 34 receives the regulating signal from the toggle switch 32 and converts the signal into electronic commands to control the speed at which the compression component 51 driven by the drive motor 52 operates. The compression component 51 can be a piston 512 with a rod or a diaphragm, enabling it to compress the water in the water outlet pump 2 into the jet assembly 11 through a certain speed of movement. The drive motor 52 is a commonly used servo motor or stepper motor, etc.

[0054] In the embodiments of this utility model, please refer to Figure 5The control component 34 includes a linkage gear 341 and a speed regulator 342. The linkage gear 341 is meshed with a toggle switch 32 and is fixedly connected to the speed regulator 342 via a transmission shaft. The speed regulator 342 is electrically connected to the drive motor 52. The linkage gear 341 can be a metal or plastic gear that meshes with a rack on the toggle switch 32. The rotation of the toggle switch 32 drives the linkage gear 341 to rotate synchronously. The linkage gear 341 is fixedly connected to the speed regulator 342, which can be an electronic speed control device with a circuit board. The speed regulator 342 adjusts the speed of the drive motor 52 according to the rotation of the linkage gear 341, thereby changing the water pressure and water speed of the water pump 2. Optionally, the oral irrigator may also include a battery 7 disposed in the cavity. The speed controller 342 and the drive motor 52 are both electrically connected to the battery 7, thereby powering the circuit board on the speed controller 342 and the drive motor 52. This eliminates the need for an external power cord, improving user comfort.

[0055] In the embodiments of this utility model, please refer to Figure 6 The compression assembly 51 includes a connecting rod 511 and a piston 512. One end of the connecting rod 511 is fixedly connected to the drive motor 52, and the other end of the connecting rod 511 is connected to the piston 512, which is movably disposed inside the water pump 2. The connecting rod 511 can be a rod-shaped structure made of metal or engineering plastic, with one end fixedly connected to the drive motor 52 and the other end connected to the piston 512. The number of pistons 512 is not specifically limited; for example, there can be one or two, depending on the maximum water pressure required by the press 100. The piston 512 can be a circular, elastic disc-shaped structure. The connecting rod 511 transmits power from the drive motor 52, and its reciprocating motion drives the piston 512 to move accordingly inside the water pump 2.

[0056] In the embodiments of this utility model, please refer to Figure 5 The water flosser also includes a transmission mechanism 6, which connects the drive motor 52 and the connecting rod 511 to move the connecting rod 511 closer to or further away from the water pump 2. The transmission mechanism 6 can be various mechanical components, such as gears, belts, chains, or sliders, used to connect the drive motor 52 and the connecting rod 511. For example, it can be a transmission system composed of small gears and chains. The transmission mechanism 6 converts the rotational motion of the drive motor 52 into the linear motion of the connecting rod 511, thereby driving the piston 512 to move accordingly inside the water pump 2.

[0057] In the embodiments of this utility model, please refer to Figure 6The transmission mechanism 6 includes a driving gear 61 and a driven gear 62, which are meshed together. The rotation axis of the driving gear 61 and the rotation axis of the driven gear 62 are perpendicular to each other. The driving gear 61 is fixedly mounted on the output shaft of the drive motor 52, and the driven gear 62 is fixedly connected to a connecting rod 511. In this embodiment, the driving gear 61 can be a spur gear or a helical gear, and the driven gear 62 can be a crown gear. Through the meshing connection of the driving gear 61 and the driven gear 62, which can adopt a spur gear or helical gear meshing design, efficient power transmission from the drive motor 52 to the connecting rod 511 can be achieved.
