Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fluid control, in particular to a rotating water outlet faucet. BACKGROUND

[0002] In the field of fluid control, valve core as a key component to control water flow switch and flow, is widely used in various water faucets and other fluid control devices.

[0003] In the related art, the porcelain disc valve core is a relatively traditional and common type of valve core, which provides a relatively stable solution for fluid control in a certain period of time. However, with the growth of use demand and the diversification of use scenarios, the currently used porcelain disc valve core gradually exposes many serious problems. From the aspect of durability: the porcelain disc valve core is usually made of brittle materials such as porcelain, and in the process of frequent use in daily life, such as adjusting the water flow size and turning on / off the water for many times, the parts of the valve core are prone to wear and collision. Moreover, the porcelain disc itself is relatively brittle, and under the impact of a certain external force or the influence of natural aging after long-term use, it is easy to crack or even break, which causes the valve core to fail to work normally, greatly shortens its service life, and increases the user's use cost and the maintenance frequency of the equipment. In terms of anti-dripping performance: the performance of the porcelain disc valve core is also unsatisfactory. Since the sealing of the porcelain disc valve core mainly relies on the close fit between the porcelain discs, after long-term use, the surface of the porcelain disc will not be smooth due to wear, corrosion and other factors, resulting in small gaps. Under the action of water pressure, these small gaps will cause water to slowly seep out, forming a dripping phenomenon. In the kitchen environment, the dripping water will keep the countertop in a wet state, which is easy to breed bacteria and mold, affecting food safety and hygiene. In the bathroom environment, the long-term dripping water on the floor will make the floor slippery, increasing the risk of slipping and falling, and also causing damage to the walls and other surrounding areas of the bathroom, affecting the overall appearance and service life of the environment.

[0024] In the field of fluid control technology, the valve core is a key component for controlling the opening and closing of water flow and flow, and is widely used in various fluid control devices such as faucets.

[0025] In the related art, the porcelain disc valve core is a relatively traditional and common type of valve core, which has provided a relatively stable solution for fluid control in a certain period of time. However, with the growth of use demand and the diversification of use scenarios, the currently used porcelain disc valve core gradually exposes many serious problems. From the aspect of durability: the porcelain disc valve core is usually made of brittle materials such as ceramics, and in the process of frequent use in daily life, such as adjusting the water flow size and turning on and off the water for many times, wear and collision between the parts of the valve core are easy to occur. Moreover, the porcelain disc itself is brittle, and under the impact of a certain external force or the influence of natural aging after long-term use, it is easy to crack or even break, which causes the valve core to fail to work normally, greatly shortens its service life, and increases the user's use cost and the maintenance frequency of the equipment. In terms of anti-dripping performance: the porcelain disc valve core also does not meet expectations. Since the sealing of the porcelain disc valve core mainly relies on the close fit between the porcelain discs, but after long-term use, the surface of the porcelain disc will not be smooth due to wear, corrosion and other factors, so that small gaps will appear. Under the action of water pressure, these small gaps will cause water to slowly seep out, forming a dripping phenomenon. In the kitchen environment, dripping water will keep the countertop in a wet state, which is easy to breed bacteria and mold, affecting food safety and hygiene; in the bathroom environment, the ground will be wet and slippery for a long time, increasing the risk of slipping and falling, and also causing damage to the walls and other surrounding walls in the bathroom, affecting the overall appearance and service life of the environment.

[0026] Therefore, as Figures 1 to 4As shown, the rotating water outlet faucet provided by the present application comprises a water pipe 100, a water sealing rubber ring 200, a valve core 300 and a rotating lifting structure. The water pipe 100 comprises a water inlet section 101, a water outlet section 102 and a mounting section 103. The water sealing rubber ring 200 is located between the water inlet section 101 and the water outlet section 102. The valve core 300 is installed on the mounting section 103 and fixedly connected with the water sealing rubber ring 200. Specifically, the rotating lifting structure is used to drive the valve core 300 and the mounting section 103 to establish a transmission connection. The rotating lifting structure comprises a guide groove 301 and a pushing piece 1031. The guide groove 301 is arranged on the peripheral wall of one of the valve core 300 and the mounting section 103 and extends in the circumferential direction. The pushing piece 1031 is fixed to the other one of the valve core 300 and the mounting section 103. Further, the pushing piece 1031 is in sliding abutting cooperation with the groove wall of the guide groove 301. At least one extension path of the guide groove 301 is offset relative to the axial direction of the valve core 300. For example, the guide groove 301 comprises an offset section 3011. The offset section 3011 extends obliquely in the lateral direction. Thus, when the valve core 300 rotates in the circumferential direction, the valve core 300 can move axially to block or open the water outlet section 102. It should be noted that by arranging the rotating lifting structure composed of the guide groove 301 and the pushing piece 1031 between the valve core 300 and the mounting section 103, the valve core 300 can move axially by means of the axially offset path of the guide groove 301 when rotating in the circumferential direction, thereby driving the water sealing rubber ring 200 to move to block or open the water outlet section 102. The present application discards the traditional ceramic valve core 300 which relies on the brittle ceramic material and the sealing between the ceramic pieces, and adopts a more durable mechanical transmission and elastic sealing combined design. Not only does it significantly improve the overall structural strength and wear resistance of the faucet, effectively avoiding failure problems such as component fragmentation and wear caused by frequent rotation or external impact, prolonging the service life of the faucet and reducing the maintenance and replacement frequency, but also it directly drives the water sealing rubber ring 200 to achieve precise opening and closing by axial movement of the valve core 300, thereby enhancing the sealing reliability, effectively preventing the dripping and leakage phenomenon caused by aging or wear of the sealing surface, improving the anti-dripping performance, thereby ensuring the hygiene and safety of the use environment and improving the user experience.

[0027] Optionally, the water inlet section and the water outlet section are arranged obliquely (not shown in the figure). In some embodiments of the present application, as shown in Figure 1 and Figure 3As shown, the water inlet section 101 and the water outlet section 102 are arranged vertically, and the valve core 300 is connected and drives the water sealing rubber ring 200 to move along the center line direction of the water outlet section 102 to block or open the water outlet section 102. By adopting the inclined or vertical arrangement, combined with the structure that the valve core 300 drives the water sealing rubber ring 200 to move along the center line direction of the water outlet section 102, the spatial layout of the water flow channel is optimized, the water flow path is more direct and smooth, the internal water flow resistance and turbulence phenomenon are reduced, and the water outlet efficiency and stability are improved. At the same time, the arrangement mode makes the sealing action of the water sealing rubber ring 200 and the center line direction of the water outlet section 102 accurately matched, and the water sealing rubber ring 200 is directly pushed along the center line direction to tightly fit or separate the outlet of the water outlet section 102 by the axial movement of the valve core 300, for example, the water outlet section 102 is a stepped structure, and the water sealing rubber ring 200 can be pressed against or separated from the end face of one of the steps to block or open the water outlet section 102. For this, the fitting degree and uniformity of the sealing contact surface are significantly enhanced, the local leakage problem caused by the deviation or uneven force of the traditional valve core 300 is effectively avoided, the anti-dripping performance is further improved, and it is especially suitable for installation scenes with high requirements for water outlet direction and sealing precision, thereby enhancing the practicability and reliability of the faucet.

[0028] Referring again to Figure 1 , Figure 2 and Figure 4In some embodiments of the present application, the peripheral wall of the valve core 300 is provided with an inwardly protruding mounting annular portion 310, and the outer peripheral wall of the water sealing rubber ring 200 is provided with a recessed annular groove 201 matched with the mounting annular portion 310. The mounting annular portion 310 is in abutting fit with the groove wall of the recessed annular groove 201 to drive the water sealing rubber ring 200 to be fixed with the valve core 300. Further, the stable connection of the water sealing rubber ring 200 with the valve core 300 is achieved by the abutting fit of the groove walls of the two, which simplifies the installation process of the water sealing rubber ring 200, reliably fixes it by physical fitting without complex fixing parts, and enhances the assembly consistency of the water sealing rubber ring 200 with the valve core 300. After installation, the close fit of the mounting annular portion 310 with the recessed annular groove 201 can effectively limit the risk of the water sealing rubber ring 200 coming off the valve core 300 during the common process with the valve core 300, ensuring that the water sealing rubber ring 200 is always in a precise installation position, thereby guaranteeing the sealing effect of the water sealing rubber ring 200 with the outlet section 102 and improving the accuracy of the opening and closing control and the reliability of the drip-proofing. Meanwhile, this structure is easy to process and manufacture, reducing the production cost and assembly difficulty. In particular, for the water dispenser faucet, the existing water sealing ring in the water dispenser faucet is separately arranged with the valve core 300, and under the condition of high water pressure of the barrel water, the water sealing ring is easily washed off, causing the water dispenser faucet to leak. The present application directly fixes the water sealing rubber ring 200 to the valve core 300 and makes it move together with the valve core 300, thereby eliminating the problem of the water sealing rubber ring 200 being washed off. In experimental tests, the water sealing rubber ring 200 does not show position deviation after 1000 repeated opening and closing under the water pressure of 10 kg, and the service life is far longer than that of the current water dispenser faucet. Optionally, the water sealing rubber ring 200 is a silicone product meeting the health and safety standards and is suitable for the health standard requirements of the water dispenser faucet. Considering that the water sealing rubber ring 200 is installed in the valve core 300 by elastic deformation interference, in some processing and assembly applications, the end face of the water sealing rubber ring 200 is provided with a deformation groove 202 for the water sealing rubber ring 200 to deform inwardly when it is inserted into the valve core 300. In this regard, the installation process of the water sealing rubber ring 200 is simplified, reliable fixation is achieved by physical fitting without complex fixing parts, and the assembly consistency of the water sealing rubber ring 200 with the valve core 300 is enhanced. Moreover, after installation, the close fit of the mounting annular portion 310 with the recessed annular groove 201 can effectively avoid the risk of the water sealing rubber ring 200 coming off, ensuring that the water sealing rubber ring 200 is always in a precise position, thereby guaranteeing the sealing effect of the water sealing rubber ring 200 with the inner wall of the outlet section 102, improving the accuracy of the opening and closing control and the reliability of the drip-proofing, and simultaneously, this structure is easy to process and manufacture, reducing the production cost and assembly difficulty. In order to further improve the firmness of the installation of the water sealing rubber ring 200, in some embodiments of the present application, the water sealing rubber ring 200 is provided with a rigid retainer 400, which can be inserted into the deformation groove 202 after the water sealing rubber ring 200 is installed in the valve core 300, to block the water sealing rubber ring 200 from deforming inwardly and falling off the valve core 300.It can be understood that after assembly, the rigid retainer 400 can fill the elastic compensation space of the deformation groove 202, making it difficult for the water sealing rubber ring 200 to deform and cause the valve core 300 to fall off, thereby further improving the sealing performance and installation compatibility of the water sealing rubber ring 200, and ensuring the anti-dripping effect and long-term use stability of the faucet. Optionally, the rigid retainer 400 is a metal or hard plastic piece. It can be understood that the deformation groove 202 is located at one end of the water sealing rubber ring 200 away from the water outlet section 102, so that the rigid retainer 400 installed in the deformation groove 202 does not come into contact with the liquid to be contaminated. In some embodiments, the end of the water sealing rubber ring 200 towards the water outlet section 102 is provided with a buffer groove, which can buffer the water flowing from the water inlet section 101 when the water outlet section 102 is opened, thereby reducing the impact force on the water sealing rubber ring 200, avoiding the position deviation of the water sealing rubber ring 200 affecting the sealing effect, at the same time, the water sealing rubber ring 200 can also withstand greater water pressure, and the service life is also greatly improved.

[0029] Referring to Figure 1 , Figure 2 and Figure 4In some embodiments of the present application, the guide grooves 301 are arranged on the valve core 300, and there are two guide grooves 301 arranged at an interval of 180° in the circumferential direction of the valve core 300. The pushing piece 1031 is fixed to the mounting segment 103, and the two ends of the pushing piece 1031 are respectively arranged in the two guide grooves 301 and are in sliding fit with the guide grooves 301. The symmetrical double-guide-groove 301 structure design makes the force more balanced when the valve core 300 rotates in the circumferential direction. In application, the two-side guide grooves 301 synchronously guide the force of the pushing piece 1031, avoiding the local wear or eccentric load problem caused by the force concentration of the single-side guide groove 301, and improving the transmission stability and reliability of the rotating lifting structure. In addition, the cooperative action of the double-guide-groove 301 ensures the linearity and stability of the axial movement of the valve core 300, so that the water sealing rubber ring 200 can move along the center line direction of the water outlet segment 102 accurately, further enhancing the accuracy of sealing control and the anti-dripping performance. At the same time, this layout improves the overall rigidity and durability of the structure, prolonging the service life of the faucet. Optionally, the peripheral wall of the mounting segment 103 is provided with a through hole 10301 penetrating in the radial direction, and the pushing piece 1031 is arranged in the through hole 10301 and abuts against the hole wall of the through hole 10301; or, the peripheral wall of the mounting segment is provided with a threaded hole penetrating in the radial direction, and the middle part of the pushing piece is threadedly connected with at least one threaded hole (not shown in the figure); the two ends of the pushing piece 1031 respectively extend into the two guide grooves 301 and abut against the groove walls of the guide grooves 301. Among them, the through hole 10301 mounting mode has simple structure and convenient assembly, and is suitable for scenes with low requirement for the position accuracy of the pushing piece 1031, while the threaded hole mounting mode threadedly rotates the pushing piece 1031, enhancing the cooperation stability of the pushing piece 1031 and the guide groove 301. Both of the two modes ensure that the pushing piece 1031 can reliably transmit the force when the valve core 300 rotates in the circumferential direction, drive the valve core 300 to move axially accurately, improve the transmission accuracy and durability of the rotating lifting structure, and enhance the flexibility and applicability of the faucet design, ensuring the reliability of the water outlet control. In other embodiments, the guide grooves are arranged on the peripheral wall of the mounting segment and are arranged at an interval of 180° in the circumferential direction of the mounting segment (not shown in the figure). In still other embodiments, there is only one guide groove arranged on the peripheral surface of the valve core, or there is only one guide groove arranged on the peripheral wall of the mounting segment (not shown in the figure). Optionally, the circumferential extension angle of the guide groove 301 is <180°, and the axial offset distance of the guide groove 301 is ≤5 mm, balancing the convenience of operation and the accuracy of sealing. In this regard, the user can intuitively judge the on-off state of the water flow through the explicit rotation range. Preferably, the axial offset distance A=3 mm, and the circumferential extension angle of the guide groove 301 is 150°.

[0030] It should be noted that compared with the conventional pure linear or pure parabolic water flow variation curve, a reasonable rotating opening degree can be designed according to the adaptive design of the circumferential rotation angle and the axial offset amount, so that the water flow variation curve can be more diversified. For example, in the application of rotating opening, a smaller axial offset distance can be designed in the front rotation, a larger axial offset distance can be designed in the middle rotation, and a moderate axial offset distance can be designed in the rear rotation. As the user usually uses the front rotation, the water flow is smaller when the faucet is opened, which can save water resources and help the user save water fees.

[0031] Referring again to Figure 4 In some embodiments of the present application, the extension path of the end of the guide groove 301 coincides with the circumference of the valve core 300, so as to keep the valve core 300 at the current axial position after the axial movement. For example, the guide groove 301 includes a coinciding section 3012, so that after the axial movement of the valve core 300 is completed and the valve core 300 is rotated to the target position, the abutting piece 1031 can slide along the circumferentially coinciding path to a stable position, thereby locking the valve core 300 at the current axial position, preventing the valve core 300 from changing the on-off state of the water outlet section 102 due to accidental axial movement caused by external vibration or accidental touch. The locking function significantly improves the stability and reliability of the faucet during use, ensures the persistent maintenance of the sealing state, effectively avoids the problem of dripping or leaking in the non-operation state, and simplifies the operation process of the user, so that the user can maintain the water control state without additional locking force, thereby optimizing the use experience and safety.

[0032] In some embodiments of the present application, the groove wall at one end of the guide groove is provided with a stop groove (not shown in the figure) arranged in the axial direction of the valve core, for example, the shape of the stop groove matches the shape of the circumferential surface of the abutting piece, such as a semicircular arc. When the abutting piece enters the stop groove, the valve core moves axially by a preset distance and is kept at the axial position after the movement. By integrating the axial stop structure, when the valve core is rotated to a certain angle, not only can the axial movement be realized to control the on-off of the water outlet section, but also a controllable displacement in the axial direction can be further generated, thereby enhancing the sealing force of the water sealing rubber ring and improving the tightness and stability of the sealing. It should be noted that the stop groove can mechanically limit the valve core after reaching the target working position, avoid accidental displacement caused by water flow impact, operation inertia or external interference, effectively guarantee the persistence and reliability of the sealing state, and also provide a more obvious feedback to the user, further optimizing the accuracy and experience of the user in controlling the water flow.

[0033] Referring again to Figure 1 and Figure 2In some embodiments of the present application, the outer periphery of the valve core 300 is provided with a waterproof ring 500, which is located on the side of the push piece 1031 facing the water inlet section 101 and is in abutting contact with the inner wall of the mounting section 103. The waterproof ring 500 can block the penetration path of the water flow in the water inlet section 101 to the key components of the rotating lifting structure, such as the push piece 1031 and the guide groove 301, thereby avoiding problems such as rusting of metal components, swelling of plastic components, or transmission jamming caused by long-term erosion of water flow, significantly improving the service life and operation stability of the rotating lifting structure. At the same time, the waterproof ring 500 prevents damage or failure of components caused by internal water leakage, enhances the overall sealing and durability of the faucet, and ensures the long-term reliability and safety of water control. The waterproof ring 500 blocks the water flow in the water inlet section 101 to the push piece 1031.

[0034] Referring again to Figure 1 In some embodiments of the present application, the valve core 300 is fixedly connected with a handle 600, which is located on the outer side of the water pipe 100 to provide an intuitive and convenient operation entrance for users. Users can directly drive the valve core 300 to rotate circumferentially by swinging the handle 600, and then realize the axial movement of the water sealing rubber ring 200 and the on-off control of the water outlet section 102 through the rotating lifting structure. The handle 600 is directly and efficiently connected to the valve core 300, which improves the convenience and comfort of the user in controlling the faucet. At the same time, the stable connection between the handle 600 and the valve core 300 ensures the accurate transmission of operating force, avoiding the problems of operation failure or response delay caused by loose connection, further enhancing the operation performance and use reliability of the faucet, and optimizing the overall user experience and market competitiveness.

[0035] In addition, referring again to Figure 1 In some embodiments of the present application, the water outlet section 102 is provided with a water outlet nozzle 700, which can make the water flow output more gentle.

[0036] The embodiments of the present application have been described in detail above with reference to the accompanying drawings, but the present application is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.

The feature of rotating the water tap is that, include: Water pipes include inlet section, outlet section, and installation section; A water-sealing rubber ring is located between the water inlet section and the water outlet section; The valve core is installed in the mounting section and fixedly connected to the sealing rubber ring; A rotating lifting structure is used to drive the valve core and the mounting section to establish a transmission connection. The rotating lifting structure includes a guide groove and a pushing member. The guide groove is disposed on the peripheral wall of one of the valve core and the mounting section and extends in the circumferential direction. The pushing member is fixed to the other of the valve core and the mounting section. The pusher is slidably engaged with the wall of the guide groove, and at least one section of the extension path of the guide groove is offset relative to the axial direction of the valve core. When the valve core rotates circumferentially, the valve core can move axially to block or open the water outlet section.

2. The rotating water tap according to claim 1, characterized in that: The inlet section and the outlet section are arranged at an angle or vertically. The valve core is connected to and drives the sealing rubber ring to move along the center line of the outlet section to block or open the outlet section.

3. The rotating water tap according to claim 1, characterized in that: The valve core has an inwardly protruding mounting annular portion on its peripheral wall, and the sealing rubber ring has a concave annular groove on its outer peripheral wall that mates with the mounting annular portion. The mounting annular portion abuts against the groove wall of the concave annular groove to drive the sealing rubber ring to be fixed to the valve core.

4. The rotating water tap according to claim 3, characterized in that: The end face of the sealing rubber ring is provided with a deformation groove so that the sealing rubber ring deforms inward when it is inserted into the valve core.

5. The rotating water tap according to claim 4, characterized in that: The sealing rubber ring is provided with a rigid retainer. After the sealing rubber ring is installed on the valve core, the rigid retainer can be inserted into the deformation groove to prevent the sealing rubber ring from deforming inward and falling off the valve core.

6. The rotating water tap according to any one of claims 1 to 5, characterized in that: The guide groove is disposed on the valve core. There are two guide grooves, which are arranged 180° apart in the circumferential direction of the valve core. The push member is fixed to the mounting section. The two ends of the push member are respectively placed in the two guide grooves and slide in cooperation with the guide grooves.

7. The rotating water tap according to claim 6, characterized in that: The extension path of the end of the guide groove coincides with the circumferential direction of the valve core, so as to maintain the valve core in the current axial position after axial movement.

8. The rotating water tap according to claim 6, characterized in that: The peripheral wall of the mounting section is provided with a radially penetrating through hole, and the pushing member passes through the through hole and abuts against the hole wall; or, the peripheral wall of the mounting section is provided with a radially penetrating threaded hole, and the middle part of the pushing member is threadedly connected to at least one of the threaded holes; the two ends of the pushing member extend into the two guide grooves respectively and abut against the groove walls of the guide grooves.

9. The rotating water tap according to claim 1, characterized in that: A waterproof ring is installed on the outer periphery of the valve core. The waterproof ring is located on the side of the pusher facing the water inlet section and presses against the inner peripheral wall of the mounting section to block the water inlet section from flowing to the pusher.

10. The rotating water tap according to claim 1, characterized in that: The valve core is fixedly connected to a handle, which is located on the outside of the water pipe and can drive the valve core to rotate.
