Description

Technical Field

[0001] This utility model belongs to the field of oral irrigator technology, and in particular relates to an oral irrigator flow regulating mechanism. Background Technology

[0002] Brushing teeth is the most common dental hygiene practice. However, most toothbrushes cannot penetrate the gaps, grooves, and fissures of the chewing surfaces with toothpaste. Therefore, a water flosser is needed as an auxiliary tool to clean teeth. Water flossers are essential hygiene products in many households. The cleaning effect of a water flosser is mainly achieved by the impact force of a high-speed jet of water under certain pressure. Currently available electric water flossers are expensive, require charging or batteries, and are relatively bulky. A faucet with a built-in water flosser has emerged, offering both regular water flow and water flossing functions. However, these faucets have two water channels, requiring users to manually switch between them to use the water flosser. Furthermore, the switching mechanism occupies valuable space within the faucet, increasing its size and aesthetics. Additionally, the nozzle replacement mechanism and water channel switching mechanism are separate, requiring manual switching back to the flushing port after changing the nozzle, making operation cumbersome. The applicant previously disclosed patent CN221013542U, a water outlet component and a faucet water flosser, comprising: a water flosser body and a nozzle; the water flosser body has a water inlet channel, a first flow channel and a second flow channel are provided inside the water flosser body, and a switch valve body for connecting or disconnecting the water inlet channel and the first flow channel; the water flosser body also has a chamber for installing the nozzle, and an operating component for opening the chamber, the operating component being connected to a switching component via a reversing component; when the operating component opens the chamber, the operating component drives the switching component to move from a first position to a second position via the reversing component, connecting the nozzle to the water inlet channel through the second flow channel and closing the first flow channel. This utility model also provides a faucet water flosser, comprising: a switch handle, a faucet support base, and the above-mentioned water outlet component; the faucet support base is placed on a mounting platform, and the switch handle is movably connected to the faucet support base for connecting or disconnecting the water inlet pipe from the water outlet component. However, existing water flossers cannot adjust the water flow and pressure, or the adjustment is inconvenient, or the overall size of the water flosser is large, making it inconvenient to use and resulting in a poor user experience. Alternatively, in order to achieve the above functions, the overall structure of the water flosser is complex and the size is large, making it inconvenient to use. Utility Model Content

[0003] This invention provides a flow regulating mechanism for a dental flosser, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A water flosser flow regulating mechanism includes a water flosser body, a water flosser tube, an end cap, and a flow component.

[0026] Reference Figure 1-5 As shown, a water flosser flow regulating mechanism includes a water flosser body 1, a water flosser tube 2, an end cap 3, and a flow component 4. The water flosser body 1 has a water flossing hole 11, with an inlet 12 at one end and the other end connected to the water flosser tube 2. The end cap 3 is located at the end of the water flosser tube 2 of the water flosser body 1. The flow component 4 includes a knob 41, a gear linkage, and a rotating drum 45. The knob 41 is rotatably located at the end of the water flosser tube 2 of the water flosser body 1. The rotating drum 45 is located in the middle of the water flosser body 1 and passes through the water flossing hole 11. The rotating drum 41 rotates eccentrically with the water flossing hole 11 to adjust the flow rate of the water flossing hole 11. The gear linkage connects the knob 41 and the rotating drum 45, converting the horizontal rotation of the knob 41 into the vertical rotation of the rotating drum 45.

[0027] The gear linkage is provided with a gear plate 42 and a gear set 43. The gear plate 42 is located on the outside of the flushing body 1 and connected to the knob 41. The flushing body 1 is provided with a mounting groove 44 that passes through the flushing hole 11. The rotating drum 45 is rotatably located in the mounting groove 44 and is provided with an adjustment hole 451 that communicates with the flushing hole 11. The gear set 43 is located on the flushing body 1 and connects the gear plate 42 and the rotating drum 45.

[0028] The flow regulating valve's adjustment knob 41 is located at one end of the main body of the dental floss faucet, matching its round end. Users can easily adjust the flow rate with one hand. The structure is compact and integrates seamlessly with the overall appearance, resulting in a more aesthetically pleasing design. The supporting structure, including gear 42, gear set 43, mounting groove 44, and rotating drum 45, is housed within the outer casing, enabling long-distance linkage adjustment within the main body 1. This facilitates the layout of other components, fully utilizing internal space. The outlet and flow regulating valve are positioned opposite each other, and the faucet's water path is distributed on both sides. The structural layout is reasonable and compact, and it also facilitates the assembly of various components. In use, rotating the knob 41 drives the gear 42 to rotate. The lower tooth surface of the gear 42 meshes with the gear set 43, causing the gear set 43 to rotate. Since the gear set 43 is connected to the rotating drum 45, it drives the drum 45 to rotate within the mounting groove 44. The rotation of the drum 45 causes the adjustment hole 451 to misalign with the dental floss water path, changing the size of the through hole and thus adjusting the water flow.

[0029] The transmission is achieved through the gear set 43, which can meet the requirements of different length distances between the gear plate 42 and the roller 46, and also meet the requirements of the installation space of the punch body, thus avoiding the problem of the length of the gear plate 42 being unfavorable to operation.

[0030] Furthermore, sealing rings 452 are provided between both ends of the rotating drum 45 and the punch body 1.

[0031] To prevent water leakage from the roller 45, a sealing ring 452 can also be installed between the adjustment hole 451 of the roller 45 and the flushing hole 11 of the punch body 1 to increase waterproofness.

[0032] Furthermore, the gear set 43 of the rotating drum 45 extends out of the punch body 1 at the opposite end, and the extended end of the rotating drum 45 is provided with a buckle 453.

[0033] The buckle 453 rotates and fixes the rotating drum 45 into the mounting groove 44, which is convenient for installation and has a good adjustment effect.

[0034] Furthermore, the knob 41 is provided with anti-slip teeth 411 on its outer periphery.

[0035] Knob 41 is easy to operate.

[0036] Furthermore, the punch body 1 is provided with a limiting protrusion (not shown) corresponding to the rotation range of the gear plate 42.

[0037] To prevent disengagement from gear set 43 or damage to other components.

[0038] Furthermore, the main body 1 of the tooth-flushing device is also provided with a faucet water hole 5, the flushing hole 11 is located at the center of the main body 1 of the tooth-flushing device, the faucet water hole 5 is located on the outer periphery of the flushing hole 11 and connected to the water inlet 12, and the water inlet 12 is provided with a switching valve 6.

[0039] It has enriched the product's functionality.

[0040] Furthermore, the water outlet 51 of the faucet water hole 5 is located on the side of the flushing body 1.

[0041] Furthermore, the outlet 51 is provided with a face opposite to the gear set 43, and the outlet 51 is provided with an aerator.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
