Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a dual-control faucet. Background Technology

[0002] Existing basin faucets or concealed faucets can dispense both cold and hot water, and correspondingly, they often have one or two switches. In the case of a dual-switch structure, one switch is a flow control switch and the other is a temperature control switch. These two control switches are often located on the faucet body or near the installation position on the water outlet pipe. Such a switch structure causes congestion in the faucet body or the base of the water outlet pipe, and seriously affects the structural and aesthetic design of the faucet, thus significantly limiting its appearance. Therefore, this utility model provides a new faucet structure that can solve the above-mentioned technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a double-head structure with minimal limitations in appearance and structural design.

[0004] A dual-control faucet includes a main water outlet body and a water outlet pipe fitting, wherein,

[0005] The main water outlet body is provided with an installation cavity, a cold water channel, and a hot water channel. One end of the installation cavity has two water inlets, which are respectively connected to the cold water channel and the hot water channel, and the other end forms a mixing water channel. A mixing valve core is installed in the installation cavity. The water inlets at both ends of the mixing valve core are respectively connected to the two water inlets, and the peripheral water outlet is connected to the mixing water channel. The mixing valve core can control the water supply ratio of the cold water channel and the hot water channel, thereby adjusting the water temperature of the mixing water channel.

[0006] The water outlet fitting is installed at the mounting port of the mounting cavity, and the water inlet end of the water outlet fitting is coaxial with and connected to the mounting cavity. A temperature control component for a linkage mixing valve core is installed inside the water inlet end of the water outlet fitting. The temperature control component has a temperature adjustment handle extending from the periphery of the water outlet fitting, allowing the user to control the water temperature. Downstream of the temperature control component, a flow control component is also installed on the water outlet fitting, thus forming a structure where the temperature control component and the flow control component are staggered.

[0007] The dual-control faucet provided by this utility model sets the temperature control component and the flow control component at different positions on the water outlet pipe, thereby avoiding the situation where the two switches are set together and the installation position is large and crowded, reducing the impact on the appearance design of the faucet, and allowing for greater design space for the faucet.

[0008] Preferably, a pressing ring is threadedly assembled inside the mounting opening of the mounting cavity. The pressing ring presses the mixing valve core into the mounting cavity, and the pressing ring has a connecting hole that axially connects the spaces at both ends. The valve stem of the mixing valve core passes through the pressing ring and extends into the inlet end of the outlet pipe to mate with the temperature control component. This reduces the depth of the mounting cavity, preventing the outlet body from becoming too large, and also reduces the axial dimension of the temperature control component.

[0009] Preferably, the temperature control component further includes a rotating seat, which is rotatably installed inside the water outlet end of the water outlet pipe fitting. The temperature adjustment handle is a rod that passes through the arc-shaped strip hole around the water outlet pipe fitting and connects with the rotating seat.

[0010] Preferably, a linkage component is installed at the end of the rotating seat facing the mixing valve core. The linkage component has a slot that is sleeved on the outer periphery of the valve stem end of the mixing valve core, so that the rotating seat can stably drive the valve stem to rotate when it rotates.

[0011] Preferably, the outlet end of the water outlet fitting is provided with a limiting step facing the mixing water channel. One end of the rotating seat abuts against the limiting step, and the other end abuts against the valve stem of the mixing valve core, thereby improving the installation stability of the rotating seat and preventing shaking. In addition, the periphery of the water outlet fitting is provided with a screw hole, and the arc-shaped strip hole is set within the rotation trajectory of the screw hole. One end of the temperature control handle is provided with threads, and it passes through the arc-shaped strip hole from the outside of the water outlet fitting and is screwed into the screw hole of the rotating seat, further limiting the rotation seat. To prevent water leakage, the periphery of the rotating seat fits against the inner wall of the water outlet fitting, and sealing rings are fitted around the outer periphery of both ends of the rotating seat. In addition, the rotating seat is provided with an axial water passage hole that connects the spaces at both ends to prevent the water outlet fitting from becoming blocked.

[0012] Preferably, to reduce the molding difficulty of the water outlet pipe fitting, it is disassembled into a pipe body and an installation cylinder. The inlet end of the installation cylinder is fitted with an installation nut, which locks the inlet end of the installation cylinder to the installation port of the installation cavity. This design is simple and easy to assemble and disassemble. The outlet end of the installation cylinder has a constricted end. The inlet end of the pipe body is inserted into the installation cylinder through the constricted end and locked in place by a fastening nut. The outer periphery of the inlet end of the pipe body has a step that abuts against the outer side of the constricted end, ensuring a reliable connection between the pipe body and the installation cylinder.

[0013] Preferably, the flow control component is located at the outlet end of the water outlet pipe fitting and serves as the outlet head of the water outlet pipe fitting, thereby increasing the function of the flow control component. At the same time, the flow control component does not form a protruding structure, which can further reduce the limitations of the faucet's appearance design.

[0014] Preferably, the flow control assembly includes a mounting base, a moving valve plate, a fixed valve plate, a switching rod, a clamping nut, a rotating sleeve, a locking nut, and a water outlet. The mounting base is fixedly installed on the outlet end of the water outlet pipe fitting by welding and has a mounting cavity that communicates with the water outlet pipe fitting. The inlet end of the mounting cavity is stepped, while the outlet end has internal threads. The moving valve plate, fixed valve plate, and switching rod are sequentially installed into the mounting cavity. The moving valve plate is rotatably positioned at the bottom of the mounting cavity, and the fixed valve plate abuts against the step inside the mounting cavity. It has a clearance hole and a drain hole in the middle and around the perimeter, respectively. One end of the switching rod is rotatably installed in the clearance hole, and its end is connected to and drives the moving valve plate to rotate. The moving valve plate seals or opens the drain hole by rotating. The other end of the switching rod is provided with a water outlet hole. The water inlet end of the water outlet hole is located near the outer periphery of the fixed valve plate and connects to the drain hole. The water outlet end is located at the end of the switching rod away from the water outlet pipe. The outer periphery of the switching rod near the fixed valve plate is also provided with a step. The clamping nut has external threads and is screwed into the water outlet end of the mounting cavity, pressing the fixed valve plate and the switching rod into the mounting cavity. The rotating sleeve is sleeved on the outer periphery of the switching rod and drives the switching rod to rotate. The locking nut is threaded onto the end of the switching rod and locks the rotating sleeve to prevent the rotating sleeve from falling off. The water outlet is installed at the water outlet end of the rotating sleeve.

[0015] Preferably, the dual-control faucet is a basin faucet, the water outlet body is columnar, the top end is provided with the mounting cavity and the water outlet pipe is installed, the bottom end is the water inlet end, and the outer periphery is provided with external threads, the cold water channel and the hot water channel extend to the bottom end of the water outlet body and form a pipe connection interface.

[0016] Preferably, the dual-control faucet is a concealed faucet and also includes a concealed mounting box. The main body of the water outlet is T-shaped, and the cold water channel and hot water channel are located on both sides of the installation cavity, forming a pipe interface. The main body of the water outlet is installed in the concealed mounting box, and the cold water channel and hot water channel are exposed through pre-reserved openings on both sides of the concealed mounting box. Limiting sleeves are installed in the openings, and the sleeves are fitted around the outer periphery of the pipe interface to keep the pipe interface and the opening coaxial and prevent wobbling. The concealed mounting box has two C-shaped rings that press against the outer periphery of the cold water channel and the hot water channel. The two ends of the C-shaped rings are locked in the concealed mounting box with screws. The structure is simple and the installation is firm. In addition, the concealed mounting box also has a level, which can be used to check whether the concealed mounting box is aligned during installation.

[0017] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:

[0018] The dual-control faucet provided by this utility model sets the temperature control component and the flow control component at different positions on the water outlet pipe, thereby avoiding the situation where the two switches are set together and the installation position is large and crowded, reducing the impact on the faucet's appearance design, and allowing the faucet to have more design space.

[0019] The valve stem of the mixing valve core passes through the pressing ring and extends into the inlet end of the outlet pipe to connect with the temperature control component. On the one hand, this reduces the depth of the mounting cavity, preventing the main body of the outlet from becoming too large. On the other hand, it also reduces the axial dimension of the temperature control component.

[0020] The water outlet pipe fitting is divided into a pipe body and an installation cylinder, which can reduce the molding difficulty of the water outlet pipe fitting;

[0021] The water inlet end of the pipe is inserted into the mounting cylinder through a constriction and locked by a fastening nut, so that a reliable connection is formed between the pipe and the mounting cylinder.

[0022] The flow control component is located at the outlet end of the water outlet pipe and serves as the outlet head of the water outlet pipe, thereby increasing the functionality of the flow control component. At the same time, the flow control component does not form a protruding structure, which can further reduce the limitations of the faucet's appearance design. Attached Figure Description

Detailed Implementation

[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0038] Please see Figures 1 to 11 A dual-control faucet includes a main water outlet body 1 and a water outlet pipe fitting 2, wherein,

[0039] The main body 1 has an installation cavity 11, a cold water channel 12, and a hot water channel 13. One end of the installation cavity 11 has two water inlets, which are respectively connected to the cold water channel 12 and the hot water channel 13, and the other end forms a mixing water channel 111. A mixing valve core 14 is installed in the installation cavity 11. The water inlets at both ends of the mixing valve core 14 are respectively connected to the two water inlets, and the peripheral water outlet is connected to the mixing water channel 111. The mixing valve core 14 can control the water supply ratio of the cold water channel 12 and the hot water channel 13, thereby adjusting the water temperature of the mixing water channel 111.

[0040] The water outlet fitting 2 is installed at the mounting port of the mounting cavity 11, and the water inlet end of the water outlet fitting 2 is coaxial with and connected to the mounting cavity 11. The water inlet end of the water outlet fitting 2 is provided with a temperature control component 23 for the linkage mixing valve core 14. The temperature control component 23 is provided with a temperature adjustment handle 231 extending from the periphery of the water outlet fitting 2, so that the user can control the water temperature through the temperature adjustment handle 231.

[0041] In one embodiment, to reduce the molding difficulty of the water outlet pipe fitting 2, it is disassembled into a pipe body 21 and an installation cylinder 22. The water inlet end of the installation cylinder 22 is fitted with an installation nut 221. The water inlet end of the installation cylinder 22 is locked to the installation port of the installation cavity 11 by the installation nut 221. The structure is simple and easy to assemble and disassemble. The water outlet end of the installation cylinder 22 is provided with a constriction. The water inlet end of the pipe body 21 is inserted into the installation cylinder 22 through the constriction and locked by a fastening nut 222. The outer periphery of the water inlet end of the pipe body 21 is provided with a step that abuts against the outside of the constriction, so that a reliable connection is formed between the pipe body 21 and the installation cylinder 22.

[0042] In one embodiment, a pressing ring 15 is threadedly assembled into the mounting opening of the mounting cavity 11. The pressing ring 15 presses the mixing valve core 14 into the mounting cavity 11, and the pressing ring 15 has a connecting hole that connects the two ends of the space. The valve stem of the mixing valve core 14 passes through the pressing ring 15 and extends into the inlet end of the water outlet pipe 2 to connect with the temperature control component 23 in the water outlet pipe 2. On the one hand, this reduces the depth of the mounting cavity 11, avoiding making the size of the water outlet body 1 too large; on the other hand, it also reduces the axial size of the temperature control component 23.

[0043] Based on the above embodiments, the temperature control component 23 further includes a rotating seat 232, which is rotatably installed inside the water outlet end of the water outlet pipe fitting 2. The temperature adjustment handle 231 is a rod that passes through the arc-shaped strip hole 223 around the water outlet pipe fitting 2 and connects with the rotating seat 232. A linkage 233 is installed at the end of the rotating seat 232 facing the mixing valve core 14. The linkage 233 has a slot that fits around the outer periphery of the valve stem end of the mixing valve core 14, so that the rotating seat 232 can stably drive the valve stem to rotate when it rotates.

[0044] Furthermore, to improve the installation stability of the rotating seat 232, a limiting step facing the mixing water channel 111 is provided inside the water outlet end of the water outlet fitting 2. One end of the rotating seat 232 abuts against the limiting step, and the other end abuts against the valve stem of the mixing valve core 14, thereby improving the installation stability of the rotating seat 232 and preventing shaking. In addition, a screw hole is provided around the periphery of the water outlet fitting 2, and the arc-shaped strip hole 223 is set within the rotation trajectory of the screw hole. One end of the temperature control handle 231 is provided with threads, and it passes through the arc-shaped strip hole 223 from the outside of the water outlet fitting 2 and is screwed into the screw hole of the rotating seat 232, further limiting the rotation of the rotating seat 232. To prevent water leakage, the periphery of the rotating seat 232 fits against the inner wall of the water outlet fitting 2, and sealing rings are fitted around the outer periphery of both ends of the rotating seat 232. In addition, the rotating seat 232 is provided with an axial water passage hole that connects the spaces at both ends to prevent the water outlet fitting 2 from becoming blocked.

[0045] On the water outlet pipe 2, downstream of the temperature control component 23, a flow control component 24 is also provided, thereby forming a structure in which the temperature control component 23 and the flow control component 24 are staggered.

[0046] In one embodiment, the flow control component 24 is disposed at the outlet end of the water outlet pipe 2 and serves as the outlet head of the water outlet pipe 2, thereby increasing the function of the flow control component 24. At the same time, the flow control component 24 does not form a protruding structure, which can further reduce the limitations of the faucet's appearance design.

[0047] Based on the above embodiments, the flow control assembly 24 includes a mounting base 241, a moving valve plate 242, a fixed valve plate 243, a switching rod 244, a clamping nut 245, a rotating sleeve 246, a locking nut 247, and a water outlet 248. The mounting base 241 is fixedly installed on the water outlet end of the water outlet pipe fitting 2 by welding, and is provided with a mounting cavity 11, which communicates with the water outlet pipe fitting 2. The inlet end of the mounting cavity 11 is stepped, while the outlet end is provided with internal threads. The moving valve plate 242, the fixed valve plate 243, and the switching rod 244 are sequentially installed into the mounting cavity 11.

The fixed valve plate 243 abuts against the step inside the mounting cavity 11 and has a clearance hole and a drain hole in the middle and around the perimeter, respectively. One end of the switching rod 244 is rotatably installed in the clearance hole, and the end is connected to and drives the moving valve plate 242 to rotate. The moving valve plate 242 blocks or opens the drain hole by rotating. The other end of the switching rod 244 is provided with a water outlet hole. The water inlet end of the water outlet hole is located near the outer periphery of the fixed valve plate 243 and is connected to the drain hole. The water outlet end is located at the end of the switching rod 244 away from the water outlet pipe 2. The outer periphery of the switching rod 244 near the fixed valve plate 243 is also provided with a step. The clamping nut 245 is provided with external threads and is screwed into the water outlet end of the mounting cavity 11, pressing the fixed valve plate 243 and the switching rod 244 into the mounting cavity 11. The rotating sleeve 246 is sleeved on the outer periphery of the switching rod 244 and drives the switching rod 244 to rotate. The locking nut 247 is threaded onto the end of the switching rod 244 and locks the rotating sleeve 246 to prevent the rotating sleeve 246 from falling off. The water outlet 248 is installed at the water outlet end of the rotating sleeve 246.

[0048] In this embodiment, please refer to Figures 1 to 6 The dual-control faucet is a basin faucet. The water outlet body 1 is columnar, with the installation cavity 11 at the top and the water outlet pipe 2 installed thereon. The bottom end is the water inlet end, and the outer periphery is provided with external threads. The cold water channel 12 and the hot water channel 13 extend to the bottom end of the water outlet body 1 and form a pipe connection interface.

[0049] In another embodiment, please refer to Figures 7 to 10The dual-control faucet is a concealed faucet and also includes a concealed box 3. The main body 1 of the water outlet is T-shaped, and the cold water channel 12 and the hot water channel 13 are located on both sides of the installation cavity 11, forming a pipe interface. The main body 1 of the water outlet is installed in the concealed box 3, and the cold water channel 12 and the hot water channel 13 are exposed through the openings reserved on both sides of the concealed box 3. The openings are fitted with limit sleeves 31, which are fitted around the outer periphery of the pipe interface to keep the pipe interface and the opening coaxial and prevent wobbling. The concealed box 3 has two C-shaped rings 32 that press against the outer periphery of the cold water channel 12 and the hot water channel 13. The two ends of the C-shaped rings 32 are locked in the concealed box 3 with screws. The structure is simple and the installation is firm. In addition, the concealed box 3 also has a level 33. During installation, the level 33 can be used to check whether the concealed box 3 is aligned during installation.

[0050] The dual-control faucet provided by this utility model sets the temperature control component 23 and the flow control component 24 at different positions on the water outlet pipe 2, thereby avoiding the situation where the two switches are set together and the installation position is large and crowded, reducing the impact on the appearance design of the faucet, and allowing for greater design space for the faucet appearance.
