Description

Technical Field

[0001] This utility model belongs to the technical field of water outlet devices, and in particular relates to a water circuit switching valve for a dental cleaning pull-out head. 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 dental flosser is needed as an auxiliary tool to clean teeth. Dental flossers are essential hygiene products in many households. Their cleaning effect is achieved primarily through the impact of a high-speed jet of water under pressure. Currently available electric dental flossers are expensive, require charging or batteries, and are relatively bulky. A new type of faucet with a built-in dental flosser has emerged, offering both regular water flow and flossing functions. However, these faucets have two water channels, requiring manual switching to use the flosser. This switching mechanism occupies valuable space within the faucet, increasing its size and aesthetics. Furthermore, the flosser nozzle replacement mechanism and water channel switching mechanism are separate, requiring manual switching back to the flosser water channel after installing 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, the existing conventional water outlet and water flosser switching switches are too simple or cumbersome. They can only control the on / off state and cannot pause the process, or they require control of the water flow, pause, and water circulation. This results in a poor user experience, or the water flosser has a complex overall structure and large size, making it inconvenient to use. Utility Model Content

[0030] Reference Figure 1-7As shown, a water path switching valve for a dental cleaning pull-out head includes a pull-out body 1, a water inlet 2, a water outlet 3, and a switching switch 4. The pull-out body 1 has a dental cleaning water path 11 and a faucet water path 12. The water inlet 2 is located at one end of the pull-out body 1, and the water outlet 3 is located on the side of the pull-out body 1 and connected to the faucet water path 12. The switching switch 4 is located between the water inlet 2 and the dental cleaning water path 11 and the faucet water path 12. When the switching switch 4 is pressed, it switches from the faucet water path 12 to the dental cleaning water path 11. When the switching switch 4 is pressed in the opposite direction, it switches from the dental cleaning water path 11 to the faucet water path 12.

[0031] This application allows for quick switching between the teeth cleaning water circuit 11 and the faucet water circuit 12 via the switch 4, eliminating the need to switch back to the faucet water circuit 12 by controlling the main valve through the faucet. This avoids impacting the lifespan of the main valve, compromising user operation, and reducing user experience.

[0032] Furthermore, the switching switch 4 is provided with a valve cylinder 41, a valve core 42, a valve stem 43, a switching spring 44, a valve cover 45, a valve seat 46, and a button 47. A valve cavity 13 is provided between the water inlet 2 and the teeth cleaning water circuit 11 and the faucet water circuit 12. The valve cylinder 41 is located in the valve cavity 13. The side of the valve cylinder 41 is provided with a teeth cleaning port 411 connected to the teeth cleaning water circuit 11. The valve core 42 is located between the faucet water circuit 12 and the valve cylinder 41. The switching spring 44 is located in the valve cavity 13 or on the valve cylinder 41 to reset the valve core 42. The valve stem 43 extends from the valve core 42 to the pull-out body 1. The valve cover 45 is located at the outer end of the valve cylinder 41 and connected to the pull-out body 1. The valve seat 46 is located on the pull-out body 1 below the valve stem 43. The middle part of the button 47 is hinged to the valve seat 46, and one end of the button 47 is hinged to the ball head of the valve stem 43.

[0033] The button 47 of the switch 4 adopts a seesaw structure. When the button 47 is pressed down, the valve stem 43 pushes the valve core 42 to block the faucet water passage 12, and the water flows from the dental cleaning port 411 into the dental cleaning water passage 11. When switching from the dental cleaning water passage 11 to the faucet water passage 12 for reset, the main valve of the inlet 2 can be closed, and the valve core 42 will reset under the action of the switching spring 44. Alternatively, the other end of the button 47 can be pressed directly, causing the button 47 to drive the ball head 431 of the valve stem 43, pulling the valve stem 43, so that the valve core 42 can quickly reset. This achieves quick switching between dental cleaning, normal faucet, and reset.

[0034] Furthermore, the switching spring 44 is disposed in the valve cavity 13 and abuts against the valve core 42.

[0035] The switching spring 44 is built into the valve cavity 13 for easy layout.

[0036] Furthermore, the valve core 42 has a spring cavity 421 at its rear end or a spring post 14 in the valve cavity 13, and the switching spring 44 is located in the spring cavity 421 or sleeved on the spring post 14.

[0037] The stability of the switching spring 44 is improved by providing at least one of the spring cavity 421 and the spring post 14.

[0038] Furthermore, the button 47 is provided with a slot 471, and one end of the valve stem 43 is provided with a ball head 431, which is slidably disposed in the slot 471.

[0039] This allows button 47 to not only press the valve stem 43 downwards to switch the water path, but also to pull the valve stem 43 in the opposite direction to reset the valve core 42.

[0040] Furthermore, the switching spring 44 is disposed between the valve cylinder 41 and the valve stem 43 or the button 47. One end of the switching spring 44 abuts against the outer end of the valve cylinder 41, and the other end abuts against the outer end of the valve stem 43 or the button 47.

[0041] The switching spring 44 is located outside the dental cleaning water circuit 11 to avoid the water circuit affecting the switching spring 44, or the switching spring 44 contaminating the water circuit or causing spring corrosion.

[0042] Furthermore, a pause component 5 is provided downstream of the switch 4. The pause component 5 includes a sealing plug 51, a release spring 52, a sealing plate 53, and a sealing seat 54. The pull-out body 1 is provided with a pause hole 15 extending from one side of the switch 4 to the dental cleaning water channel 11. The sealing plug 51 is located in the pause hole 15. A water passage groove 511 is provided at the end of the sealing plug 51. The release spring 52 is used to reset the sealing plug 51. The sealing seat 54 is located on the pull-out body 1 above the sealing plug 51. The sealing plate 53 is hinged to the sealing seat 54 and extends to the button 47 of the switch 4.

[0043] By adding a pause component 5, when cleaning teeth, pressing the button 47 down a second time causes the button 47 to move forward a certain distance, further deforming the valve core 42 and overcoming the elasticity of the release spring 52. The sealing plug 51 blocks the cleaning water passage 11, thus pausing the process. When the button 47 is released, the sealing plug 51 is pushed out by the release spring 52, reconnecting the cleaning water passage 11. This avoids the need to frequently switch the button 47.

[0044] Furthermore, the release spring 52 is disposed within the pause hole 15 and abuts against the end of the sealing plug 51.

[0045] Built-in release spring 52 for easy layout.

[0046] Furthermore, the release spring 52 is disposed between the pull-out body 1 and the sealing plate 53, and the sealing plug 51 is hinged to the sealing plate 53.

[0047] The release spring 52 is located outside the dental cleaning water circuit 11 to avoid the water circuit affecting the release spring 52, or the release spring 52 contaminating the water circuit or causing spring corrosion.

[0048] Furthermore, the teeth-cleaning water passage 11 is located at the center of the pull-out body 1, and the faucet water passage 12 is located on the outer periphery of the teeth-cleaning water passage 11.

[0049] It meets the dual requirements of teeth cleaning and normal water output.

[0050] Furthermore, the water outlet 3 is equipped with an aerator 31.

[0051] Avoid splashing water.

[0052] The switch 4 and pause component 5 simplify the valve body design, enrich the control functions, and enable product miniaturization.

[0053] 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.
