Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a metal faucet. Background Technology

[0002] In the field of fluid control, faucets, as key devices connecting pipe bases and water terminals, are widely used in various scenarios such as homes, courtyards, and outdoor venues. Water demand varies in different scenarios. For example, daily handwashing and cleaning require fixed, short-distance water flow, while irrigation and rinsing of larger areas require long-distance water supply through external water pipes. This places diverse demands on the water flow mode and connection adaptability of faucets.

[0003] Existing dual-outlet faucets, when accommodating both fixed water outlets and external water pipe connections, suffer from limited flexibility in the external components' rotation and adjustment mechanisms, resulting in limited compatibility. Furthermore, the independent control and operational coordination of the two water circuits are poor, making it difficult to simultaneously achieve both fixed water outlet and external water pipe operation. Therefore, we propose a metal faucet to address these issues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a metal faucet that can solve the problem that existing dual-outlet faucets lack a flexible rotating adjustment structure for the external components when balancing fixed water outlet and external water pipe operation, resulting in limited connectivity and poor coordination between independent control and operation of the two water circuits, making it difficult to achieve simultaneous operation of fixed water outlet and external water pipe.

[0006] To solve the above-mentioned technical problems, this utility model provides a metal faucet with the following technical solution: it includes a pipe base, a faucet is provided at the front of the pipe base, the faucet has a built-in ball stop valve, a control knob handle is provided above the ball stop valve, the control knob handle is connected to the ball stop valve, and the faucet has a limiting structure that cooperates with the control knob handle. A first water outlet with a filter is provided at the front of the faucet. A movable groove is provided in the middle of the pipe base, and a quick-connect base that can rotate 240 degrees around the axis is installed in the movable groove. The quick-connect base is used to connect an external water pipe.

[0007] Optionally, the quick-connect base includes a sealing sleeve, an inner guide tube, a rotary control valve, and a limiting boss. The sealing sleeve is rotatably and movably fitted onto the outside of the tube base. The tube base is provided with a sealing boss that fits into the sealing sleeve. The tube base has a fitting groove in the middle that matches the inner guide tube. The inner guide tube can rotate axially within the fitting groove. The inner guide tube has a T-shaped structure, and the lower part of the trapezoidal vertical section of the inner guide tube is the guide tube connection section.

[0008] Optionally, the guide pipe connecting section is provided with a non-closed annular relief groove, the relief groove retains a connecting part, and the middle, upper and lower parts of the relief groove in the vertical direction are integrally formed with the guide pipe connecting section and three limiting bosses are provided, the angle of each limiting boss is 120 degrees, and the projection positions of the three limiting bosses are consistent when viewed from the top direction.

[0009] Optionally, a rotary control valve is movably installed in the clearance groove. The rotary control valve includes an inner throttling block and an outer rotary switch. The inner throttling block can rotate between the middle and upper parts and between the middle and lower parts of the aforementioned limiting boss. The outer rotary switch is rotatably sleeved on the guide pipe connection section, and the inner throttling block and the outer rotary switch form a transmission connection.

[0010] Optionally, the outer rotary switch is fitted with two radially integrally distributed rotating bosses. The height of the rotating bosses is the same as that of the outer rotary switch. The inner throttling block and the three limiting bosses are in a mutually meshing and matching movable engagement state. By rotating the outer rotary switch 180 degrees, the inner throttling block can be driven to rotate synchronously, so that the inner throttling block and the limiting bosses do not overlap, thereby closing the pipeline to form a throttling effect.

[0011] Optionally, an outer ring thread is integrally formed directly below the flow guide pipe connection section, and a water pipe connector is rotatably installed at the outer ring thread through a threaded connection. By replacing the water pipe connector of different specifications, it can be adapted to external water pipes of different sizes.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By installing a quick-connect base that can rotate 240 degrees around the axis and a matching sealing sleeve and inner guide pipe structure, the direction of the external water pipe can be flexibly adjusted. The sealing sleeve and the sealing boss of the pipe base fit together to ensure the sealing during rotation. The T-shaped structure of the inner guide pipe effectively divides the water path. With the addition of replaceable water pipe joints of different specifications, the device can adapt to external pipes of various sizes, solving the problems of fixed direction and poor adaptability of traditional external structures, and meeting the connection needs of external pipes in different scenarios such as irrigation and flushing.

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0025] Example 1, refer to Figure 1-4In this embodiment, to address the shortcomings of existing dual-outlet faucets, which lack a flexible rotation and adjustment structure for the external components when balancing fixed water outlet and external water pipe operation, resulting in limited connectivity and poor coordination between independent control and operation of the two water circuits, making it difficult to simultaneously achieve fixed water outlet and external water pipe operation, this utility model discloses a metal faucet.

[0026] The device includes a pipe base 1, with a water outlet 2 located at the front of the pipe base 1. The water outlet 2 has a built-in ball stop valve 21 and a control knob handle 22 located above it. The control knob handle 22 is connected to the ball stop valve 21. The water outlet 2 has a limiting structure that cooperates with the control knob handle 22. A first water outlet 23 with a filter is located at the front of the water outlet 2. A movable groove 12 is located in the middle of the pipe base 1. A quick-connect base 3 that can rotate 240 degrees around the axis is installed in the movable groove 12. The quick-connect base 3 is used to connect an external water pipe. The pipe base 1 serves as the main support structure of the device, and the water outlet 2 located at the front of it constitutes the main water outlet channel. The faucet 2 has a built-in ball valve 21, which is controlled by the control knob handle 22 on the top. Rotating the control knob handle 22 drives the ball valve 21 to rotate, thereby adjusting the flow of water and the flow rate. The first water outlet 23 at the front of the faucet 2 is equipped with a filter, which can divert and filter the water, reduce water flow impact, and improve user comfort. It is suitable for fixed water outlet scenarios such as daily cleaning.

[0027] The quick-connect base 3 includes a sealing sleeve 31, an inner guide tube 32, a rotary control valve 33, and a limiting boss 3213. The sealing sleeve 31 is rotatably fitted onto the outside of the tube base 1. The tube base 1 has a sealing boss 13 that fits into the sealing sleeve 31. A fitting groove 14 matching the inner guide tube 32 is opened in the middle of the tube base 1. The inner guide tube 32 can rotate axially within the fitting groove 14. The inner guide tube 32 has a T-shaped structure, and the lower part of the trapezoidal vertical section of the inner guide tube 32 is the guide tube connection section 321. The movable groove 12 in the middle of the tube base 1 provides installation space for the quick-connect base 3. The rotation trajectory allows the quick-connect base 3 to rotate 240 degrees around the axis, facilitating adjustments to the connection direction according to the usage requirements of the external water pipe. The quick-connect base 3 integrates components such as a sealing sleeve 31 and an inner guide pipe 32. The sealing sleeve 31 is movably fitted onto the outside of the pipe body base 1 and engages with the sealing boss 13 on the pipe body base 1 to form a sealing structure, preventing water leakage along the gap between the base and the pipe body. The inner guide pipe 32 achieves axial rotation through the fitting groove 14 in the middle of the pipe body base 1. Its T-shaped structure design can effectively divert water flow, and the guide pipe connection section 321 at the bottom of the vertical section serves as a connection carrier with external components.

[0028] The guide pipe connecting section 321 has a non-closed annular clearance groove 3211. The clearance groove 3211 retains a connecting part 3212. The middle, upper and lower parts of the clearance groove 3211 are integrally formed with the guide pipe connecting section 321 and have three limiting bosses 3213. The angle of each limiting boss 3213 is 120 degrees, and the projection positions of the three limiting bosses 3213 are consistent when viewed from above. The non-closed annular clearance groove 3211 of the guide pipe connecting section 321, with its retained connecting part 3212, ensures the integrity and strength of the guide pipe structure. The three limiting bosses 3213 integrally formed with the middle, upper and lower parts of the clearance groove 3211 and the guide pipe connecting section 321 in the vertical direction are designed with a 120-degree angle and have consistent projection positions when viewed from above. This layout forms multiple sets of limiting and cooperating structures, which can achieve water flow control through interaction with rotating components.

[0029] A rotary control valve 33 is movably installed within the clearance groove 3211. The rotary control valve 33 includes an inner throttling block 331 and an outer rotary switch 332. The inner throttling block 331 is rotatably movable between the middle and upper parts and between the middle and lower parts of the aforementioned limiting boss 3213. The outer rotary switch 332 is rotatably sleeved on the guide pipe connection section 321, and the inner throttling block 331 and the outer rotary switch 332 form a transmission connection. The rotary control valve 33 movably installed within the clearance groove 3211 is the core component for realizing water flow regulation. The inner throttling block 331 and the outer rotary switch 332 are combined. The inner throttling block 331 can rotate between the middle and upper parts and between the middle and lower parts of the limiting boss 3213. Its range of motion is limited by the boss. The outer rotary switch 332 is rotatably sleeved on the guide pipe connection section 321. Through the transmission connection with the inner throttling block 331, the linkage between external operation and internal water flow control is realized. This internal and external cooperation structure enables the position of the inner throttling block 331 to be indirectly controlled by operating the external rotary switch, thereby adjusting the water flow state.

[0030] The outer rotary switch 332 is fitted with two radially integrally distributed rotating bosses 3321. The height of the rotating bosses 3321 is the same as that of the outer rotary switch 332. The inner throttling block 331 and the three limiting bosses 3213 are in a mutually meshing and matching movable engagement state. By rotating the outer rotary switch 3321 by 80 degrees, the inner throttling block 331 can be driven to rotate synchronously, so that the inner throttling block 331 and the limiting bosses 3213 do not overlap, thereby closing the pipeline and forming a throttling effect. The two radially integrally distributed rotating bosses 3321 on the outside of the outer rotary switch 332 have a height of The inner throttling block 331 and the three limiting bosses 3213 are designed to be mutually meshing and matched, providing a convenient point of force application for manual rotation to adjust the water flow. When the outer rotary switch 332 is rotated to 180 degrees, the inner throttling block 331 can be driven to rotate synchronously, so that the inner throttling block 331 and the limiting bosses 3213 switch from overlapping to non-overlapping. At this time, the limiting bosses 3213 and the inner throttling block 331 jointly close the pipeline to form a throttling effect. This structure achieves reliable control of water flow through mechanical cooperation.

[0031] The outer ring thread 3214 is integrally formed directly below the guide pipe connection section 321. A water pipe connector 4 is rotatably installed at the outer ring thread 3214 via a threaded connection. By replacing the water pipe connector 4 with different specifications, it can be adapted to external water pipes of different sizes. The integrally formed outer ring thread 3214 directly below the guide pipe connection section 321 provides a detachable threaded connection structure for the water pipe connector 4. The water pipe connector 4 can be installed and removed by rotating. This method of replacing the water pipe connector 4 with different models according to the size and specifications of the external water pipe allows the device to be adapted to external water pipes of various sizes, thereby improving the versatility and adaptability of the device.

[0032] The specific working principle is as follows: This faucet device achieves diverse water usage functions through two independently controlled water circuit systems. When a fixed front-mounted water outlet is needed, rotating the control knob handle 22 on the top of the faucet 2 opens the valve core through its transmission connection with the ball valve 21. Water flows through the internal channel of the faucet 2 and exits from the first outlet 23 with a filter. The limiting structure ensures that the knob operates within a safe angle range, suitable for daily cleaning and other scenarios. When an external water pipe is required, it can be connected via the quick-connect base 3 in the middle of the pipe base 1: Water flows through the inner guide pipe 32 to the lower connection structure, and is then opened by rotating the outer rotary valve. The boss on switch 332 drives the inner throttling block 331 to rotate synchronously. When the inner throttling block 331 and the limiting boss 3213 are in an overlapping state, the water path is unobstructed, and the water flows through the guide pipe connection section 321 and the water pipe connector 4 into the external water pipe. When the outer rotary switch 332 is rotated to 180 degrees, the inner throttling block 331 and the limiting boss 3213 are misaligned and do not overlap, and the closed pipeline achieves throttling and cutoff. At the same time, the quick-connect base 3 can rotate 240 degrees around the axis, which is convenient for adjusting the direction of the external water pipe. By replacing the water pipe connector 4 of different specifications, it can be adapted to various sizes of external pipelines. The two water system systems can be operated independently or simultaneously.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
