[0060] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0062] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0065] To meet people's aesthetic needs for simplicity, style, and minimal space consumption, existing faucets separate the water outlet component and the faucet controller. This not only makes the faucet's appearance more concise and streamlined, but also allows it to blend with various decorating styles.

[0066] A faucet controller includes a valve assembly and a handle assembly. The valve assembly can be installed on a wall or countertop, and then the handle assembly can be connected to the valve core of the valve assembly. However, the length that the valve core needs to extend outward may vary in different installation scenarios. For example, the valve core may need to extend outward relatively long when the valve assembly is installed on a wall, while it may need to extend outward relatively short when the valve assembly is installed on a countertop.

[0067] Furthermore, errors are prone to occur during valve assembly installation, especially when installed on walls. During renovations, to ensure the overall aesthetics and flatness of the wall surface, valve assemblies are typically installed first, followed by painting, tiling, or cementing. Once the wall decoration is complete, the valve assembly is fixed within the wall, its position and condition essentially determined. At this point, if the valve core's extension length is found to be incorrect, adjustment becomes extremely difficult.

[0068] If the valve core protrudes too short, the transmission connection between the handle assembly and the valve core may not fit tightly, resulting in a loose connection. During use, the handle may wobble or shift, affecting the user's normal operation of the faucet. Furthermore, prolonged loosening can lead to increased wear on the connection points, shortening the faucet's lifespan and even causing safety hazards such as leaks.

[0069] If the valve core extends too far, the base of the handle assembly may not fit snugly against the countertop or wall after installation, which can affect the stability of the handle assembly's rotation and is also unsightly.

[0070] This application provides a faucet 1 to solve the above-mentioned technical problems. Please refer to... Figure 1 and Figure 2The faucet 1 includes a water outlet assembly 20 and a faucet controller 10. The inlet of the water outlet assembly 20 is connected to the outlet of the faucet controller 10. The water outlet assembly 20 may include a connected spout 21 and a water outlet pipe. The spout 21 can be designed in different shapes, such as round or flat, to meet different water outlet needs. The water outlet pipe connects the faucet controller 10 and the spout 21, enabling the faucet controller 10 to control the water outlet status of the spout 21.

[0071] The number of faucet controllers 10 can be two, and they are located on both sides of the water outlet assembly 20. The two faucet controllers 10 can be connected to different water supply pipes, one of which is set to provide hot water and the other is set to provide cold water. In this way, the water temperature of the spout 21 can be controlled by adjusting the two faucet controllers 10.

[0072] Please see Figures 3 to 6 The faucet controller 10 includes a valve assembly 200 and a handle assembly 100. The valve assembly 200 includes a valve body 210 and a valve core 220 rotatably mounted on the valve body 210. The handle assembly 100 is detachably connected to the valve core 220 and is configured to control the valve core 220 to adjust the water flow status of the spout 21. The handle assembly 100 includes a base 110, a handle 120, a bushing 130, and a valve stem sleeve 140. The base 110 has a mounting cavity 111, the handle 120 is rotatably mounted on the top of the base 110, and the bushing 130 and the valve stem sleeve 140 are located within the mounting cavity 111. One end of the bushing 130 is fixed to the handle 120. The valve stem sleeve 140 is detachably connected to the end of the bushing 130 away from the handle 120. The end of the valve stem sleeve 140 away from the bushing 130 is provided with an interface structure 141 adapted to the valve core 220. The interface structure 141 is set to connect with the valve core 220.

[0073] In some embodiments, the mounting cavity 111 of the base 110 has an internal thread on its sidewall for connection with the valve assembly 200, and the base 110 is threadedly connected to the valve assembly 200. In this example, the installation of the base 110 is simple and has high stability, which can prevent the components of the handle assembly 100 from disengaging from the valve assembly 200, and improve the rotational stability between the handle 120, bushing 130, valve stem sleeve 140, and valve core 220.

[0074] Optionally, the interface structure 141 can be an internal spline on the end of the valve stem sleeve 140 away from the substrate, and an external spline on the outer side of the valve core 220. The valve stem sleeve 140 is fitted onto the valve core 220, and the internal spline and external spline cooperate to fix the valve core 220 and the valve stem sleeve 140 in the circumferential direction. When the user rotates the operating handle 120, the bushing 130 is rotated, which in turn rotates the valve stem sleeve 140, which in turn rotates the valve core 220. In this way, the opening degree of the valve assembly 200 can be adjusted, and the water outlet state of the water outlet assembly 20 can be controlled.

[0075] In this application, please refer to Figures 4 to 7 By providing a valve stem sleeve 140 and detachably connecting it to the bushing 130, installers can select the appropriate valve stem sleeve 140 based on the actual installation conditions. For example, when the faucet 1 is installed on a wall, a relatively long valve stem sleeve 140 can be selected; when the faucet 1 is installed on a countertop, a relatively short valve stem sleeve 140 can be selected. Furthermore, valve stem sleeves with corresponding interface structures 141 can be selected for installation based on different valve cores 220. Worn valve stem sleeves 140 can also be easily replaced individually. The valve stem sleeve 140 may include a first valve stem sleeve 143 and a second valve stem sleeve 144, the lengths of which are different, and one of them can be detachably installed with the bushing 130. Please refer to [link to relevant documentation]. Figure 4 and Figure 7 Specifically, the length of the first valve stem sleeve 143 is greater than the length of the second valve stem sleeve 144. The first valve stem sleeve 143 can be used for a handle assembly 100 that is concealed in the wall, while the second valve stem sleeve 144 can be used for a handle assembly 100 that is installed on a countertop.

[0076] Furthermore, since the valve assembly 200 is typically pre-installed concealed in the wall, the exposed dimensions of the valve assembly 200 are difficult to control, resulting in a wider range of deviations. For example, if the vendor recommends an exposed range of 10-20mm for the valve assembly 200, the exposed dimensions after installation could be 7mm / 8mm / 9mm / 21mm / 22mm / 23mm, etc. Therefore, when the exposed length of the valve core 220 is short, a longer valve stem sleeve 140 can be selected to compensate for the installation gap; when the exposed length of the valve core 220 is long, a shorter valve stem sleeve 140 can be selected, thus ensuring that the bottom surface of the base 110 fits snugly against the wall after installation. In this way, the handle assembly 100 can adapt to different installation environments and avoid installation deviations affecting installation stability.

[0077] In some specific embodiments, the length of the valve stem sleeve 140 can range from 2cm to 15cm, with specific optional lengths including but not limited to 2.0cm, 2.2cm, 2.5cm, 2.8cm, 3cm, 3.2cm, 3.5cm, 4cm, 4.5cm, 5.0cm, 5.5cm, 6.0cm, 7.0cm, 7.5cm, 8cm, 8.5cm, 9cm, 9.5cm, 10cm, 11cm, 12cm, 13cm, 14cm, and 15cm. Furthermore, the number of valve stem sleeves 140 can be flexibly set according to actual needs, such as two, three, four, or five. This application does not limit the specific number of valve stem sleeves 140.

[0078] Please see Figures 9 to 12 In some embodiments, the handle 120 is provided with a first positioning part 121, one end of the bushing 130 is provided with a second positioning part 131, and the other end is provided with a first limiting part 132, and the valve stem sleeve 140 is provided with a second limiting part 142; wherein, the first positioning part 121 cooperates with the second positioning part 131 so that the bushing 130 and the handle 120 can be installed in only one circumferential orientation, and the first limiting part 132 cooperates with the second limiting part 142 so that the bushing 130 and the valve stem sleeve 140 can be installed in only one circumferential orientation. This application, through the cooperation of the first positioning part 121 and the second positioning part 131, ensures that the bushing 130 and the handle 120 can only be installed in a single circumferential orientation, improving the accuracy and efficiency of installation. Similarly, the cooperation between the first limiting part 132 and the second limiting part 142 ensures that the bushing 130 and the valve stem sleeve 140 can only be installed in a single circumferential orientation, guaranteeing the correct fit between the components and reducing problems that may be caused by improper installation. Furthermore, the single circumferential orientation restriction helps ensure a tight connection and stable fit between the bushing 130, the handle 120, and the valve stem sleeve 140, preventing problems such as leakage and operational difficulties caused by loosening or displacement of components.

[0079] Please see Figure 12In some embodiments, the bottom of the handle 120 is provided with a mounting groove 120a. The first positioning part 121 is a positioning groove 1211 formed by the recess of the side wall of the mounting groove 120a. The second positioning part 131 is a positioning boss 1311 protruding from the outer wall of the bushing 130. One end of the bushing 130 is inserted into the mounting groove 120a. The positioning boss 1311 and the positioning groove 1211 cooperate to ensure that the bushing 130 and the handle 120 can only be installed in a single circumferential orientation. In this example, the installation of the bushing 130 and the handle 120 is simple, and the cooperation between the positioning boss 1311 and the positioning groove 1211 ensures that they can only be installed in a specific direction. During the assembly process, the installer does not need to spend a lot of time trying different installation directions; they only need to operate according to the cooperation relationship between the positioning boss 1311 and the positioning groove 1211, thus improving assembly efficiency.

[0080] Alternatively, the bushing 130 can be provided with a mounting groove 120a and form a positioning groove 1211, while the handle 120 is provided with a fixing rod that extends into the mounting groove 120a on the bushing 130, and the outer wall surface of the fixing rod is formed with a positioning protrusion that is compatible with the positioning groove 1211. Here, this application does not limit the specific form of the first positioning part 121 and the second positioning part 131.

[0081] In some embodiments, the number of positioning slots 1211 and positioning bosses 1311 is one each. In this example, by providing only one positioning slot 1211 and one positioning boss 1311, the handle 120 and bushing 130 can be installed in a single circumferential orientation, while the overall structure is simpler, reducing the number and complexity of parts. This not only reduces production costs but also simplifies the installation and disassembly process, improving production efficiency.

[0082] In some embodiments, the number of positioning slots 1211 and the number of positioning bosses 1311 are both at least two. The at least two positioning bosses 1311 are distributed at unequal angular intervals in the circumferential direction, and the positions and outer contours of the positioning slots 1211 are adapted to the positions and outer contours of the positioning bosses 1311. In this example, the number of positioning slots 1211 and the number of positioning bosses 1311 can be two, three, four, five, etc. When two positioning bosses 1311 are provided, the distance between the two positioning bosses 1311 on one side and the distance between them on the other side in the circumferential direction are not equal. This ensures that the bushing 130 and the handle 120 can only be installed in a single direction, effectively preventing directional errors during installation and improving the accuracy and reliability of the installation. Furthermore, compared to the above-mentioned solution with only one positioning boss 1311 and positioning groove 1211, the cooperation of at least two positioning bosses 1311 and at least two positioning grooves 1211 can increase the connection area and contact points between the bushing 130 and the handle 120, thereby improving the connection stability between the two and preventing relative rotation or loosening between the bushing 130 and the handle 120.

[0083] Please see Figure 13 In some embodiments, the number of positioning slots 1211 and positioning bosses 1311 is at least two, where the width L1 of one positioning boss 1311 is greater than the width L2 of the other positioning bosses 1311, and the size of the positioning slots 1211 is adapted to the size of the positioning bosses 1311. In this example, the number of positioning slots 1211 and positioning bosses 1311 can be two, three, four, five, etc. Since the width L1 of one positioning boss 1311 is greater than the width L2 of the other positioning bosses 1311, during installation, the installer can easily identify the larger positioning boss 1311 and match it with the corresponding positioning slot 1211, thereby completing the installation quickly and accurately. In this example, the unique installation direction between the handle 120 and the bushing 130 is limited by the fact that the size of one positioning boss 1311 is greater than the size of the other positioning bosses 1311. The positions of these multiple positioning bosses 1311 can be distributed at the same interval or at different intervals.

[0084] In some embodiments, a first guide surface 1312 is provided at the end of the positioning boss 1311 near the handle 120, and the first guide surface 1312 is inclined upward in the direction away from the handle 120. When installing the bushing 130 and the handle 120, the inclined first guide surface 1312 makes it easier for the positioning boss 1311 to slide into the corresponding positioning groove 1211. Even if there is a certain deviation in the operator's hand operation, the positioning boss 1311 can smoothly enter the positioning groove 1211 along the first guide surface 1312 without precise alignment, reducing the installation difficulty and improving the installation efficiency.

[0085] In some embodiments, the end of the bushing 130 away from the handle 120 is provided with a fixing groove 130a. The first limiting part 132 is a limiting groove 1321 formed by the recess of the sidewall of the fixing groove 130a. The second limiting part 142 is a limiting boss 1421 protruding from the outer wall of the valve stem sleeve 140. One end of the valve stem sleeve 140 is inserted into the limiting groove 1321, and the limiting boss 1421 cooperates with the limiting groove 1321, so that the bushing 130 and the valve stem sleeve 140 are only allowed to be installed in a single circumferential orientation. In this example, the installation operation of the bushing 130 and the valve stem sleeve 140 is simple.

[0086] The form of the first limiting part 132 and the second limiting part 142 can also be replaced.

[0087] In some embodiments, the number of limiting grooves 1321 and the number of limiting bosses 1421 are both one. In this example, by providing only one limiting groove 1321 and one limiting boss 1421, the handle 120 and the bushing 130 can be installed in a single circumferential orientation, while the overall structure is simpler, reducing the number and complexity of parts. This not only reduces production costs but also simplifies the installation and disassembly process, improving production efficiency.

[0088] In some embodiments, the number of limiting grooves 1321 and the number of limiting bosses 1421 are both at least two. The at least two limiting bosses 1421 are distributed at unequal angular intervals in the circumferential direction, and the positions of the limiting grooves 1321 and the limiting bosses 1421 are adapted to each other. In this example, the number of limiting grooves 1321 and the number of limiting bosses 1421 can be two, three, four, five, etc. When two limiting bosses 1421 are provided, the distance between the two limiting bosses 1421 on one side and the distance between them on the other side in the circumferential direction are not equal. This ensures that the bushing 130 and the valve stem sleeve 140 can only be installed in a single direction, effectively preventing directional errors during installation and improving the accuracy and reliability of the installation. Furthermore, compared to the above-mentioned solution with only one limiting boss 1421 and limiting groove 1321, the combination of at least two limiting bosses 1421 and at least two limiting grooves 1321 can increase the connection area and contact points between the bushing 130 and the valve stem sleeve 140, thereby improving the connection stability between the two.

[0089] Please see Figure 14 In some embodiments, the number of limiting grooves 1321 and the number of limiting bosses 1421 are both at least two, with the width D1 of one limiting boss 1421 being greater than the width D2 of the other limiting bosses 1421. The size of the limiting groove 1321 is adapted to the size of the limiting bosses 1421. In this example, the number of limiting grooves 1321 and the number of limiting bosses 1421 can be set to two, three, four, five, etc., with the width D1 of one limiting boss 1421 being greater than the width D2 of the other limiting bosses 1421. During installation, the installer can easily identify the larger limiting boss 1421 and match it with the corresponding limiting groove 1321, thereby completing the installation quickly and accurately. In this example, the bushing 130 and the valve stem sleeve 140 are limited by the fact that the size of one limiting boss 1421 is larger than the size of the other limiting bosses 1421. The positions of these multiple limiting bosses 1421 can be distributed at the same interval or at different intervals.

[0090] Please see Figure 14In some embodiments, the limiting boss 1421 has a second guide surface 1422 at the end near the bushing 130, and the second guide surface 1422 is inclined upward in the direction away from the bushing 130. When installing the bushing 130 and the handle 120, the inclined first guide surface 1312 makes it easier for the positioning boss 1311 to slide into the corresponding positioning groove 1211. Even if there is a certain deviation in the operator's hand operation, the positioning boss 1311 can smoothly enter the positioning groove 1211 along the first guide surface 1312 without precise alignment, reducing the installation difficulty and improving the installation efficiency.

[0091] Please see Figure 12 In some embodiments, the handle 120 may include a pivot portion 124, which is cylindrical and has a mounting groove 120a with an open bottom. The mounting cavity 111 of the base 110 has a shaft hole section 113, into which the pivot portion 124 extends and can rotate, thereby improving the stability of the relative rotation of the handle 120 and the base 110. A portion of the bottom wall of the shaft hole section 113 is recessed inward to form a fourth limiting step 114.

[0092] Furthermore, this application may also include a gasket 150, which may be made of a metal material, such as iron, copper, aluminum, etc. The gasket 150, which may be made of a metal material, is disposed on the fourth limiting step 114, located between the end face of the fourth limiting step 114 and the rotating shaft 124. This can prevent wear generated during the rotation of the handle 120 and the base 110, and improve their service life.

[0093] The end of the bushing 130 can be inserted into the mounting groove 120a and abut against the bottom wall of the mounting groove 120a. The handle 120 is also provided with a blind hole 120b, wherein the blind hole 120b is further recessed from the bottom wall of the mounting groove 120a. The bushing 130 has a through hole 130A, wherein the fixing groove 130a forms part of the through hole 130A. The handle assembly 100 also includes a connector (not shown in the figure), which passes through the through hole 130A and is fixed to the blind hole 120b to securely connect the bushing 130 and the handle 120. In this way, the handle 120 and the bushing 130 can be prevented from detaching from each other in the axial direction.

[0094] In some embodiments, a first limiting step 122 is formed on the bottom wall of the fixing groove 130a in the axial direction of the bushing 130. The first limiting step 122 is used to limit the length of the valve stem sleeve 140 extending into the fixing groove 130a. In this way, interference can be prevented when the valve stem sleeve 140 and the connector are engaged with the bushing 130.

[0095] In some embodiments, the connector is a screw, and the blind hole 120b is a threaded hole; the inner wall of the through hole 130A is provided with a second limiting step 123, the head of the screw abuts against the second limiting step 123, and the other end of the second limiting step 123 and the bushing 130 is provided with a fixing groove 130a for installing the valve stem sleeve 140. This improves the stability of the installation between the handle 120 and the bushing 130, and also prevents interference between the wall screw and the valve stem sleeve 140.

[0096] In other embodiments, the connector can be in the form of a snap-fit, and the blind hole 120b can be in the form of a snap-fit ​​hole. The snap-fit ​​is snapped to the handle 120 and the bushing 130 to achieve axial relative fixation between the handle 120 and the bushing 130.

[0097] Please refer to the following: Figure 11 and Figure 14 In some embodiments, the bushing 130 is provided with a limiting protrusion 133, and the mounting cavity 111 is provided with a third limiting step 112. The limiting protrusion 133 abuts against the third limiting step 112, which can improve the stability of the base 110 and the bushing 130 in axial relative fixation. In addition, when the base 110 is threadedly connected to the valve body 210, the bushing 130 can be driven to move axially, thereby improving the stability of the installation of the bushing 130 and the valve stem sleeve 140.

[0098] Please refer to the following: Figure 11 and Figure 14 The valve core 220 is provided with a threaded fixing hole 221, and the valve stem sleeve 140 is provided with a mounting hole 140a. A screw passes through the mounting hole 140a and is fixed to the threaded fixing hole 221 to securely connect the valve stem sleeve 140 and the valve core 220. This improves the axial stability of the valve core 220 and the valve stem sleeve 140, preventing them from detaching from each other.

[0099] Please return to the reference. Figures 9 to 11 In some embodiments, the handle assembly 100 further includes a sleeve 300, which is fitted over the outer side of the valve body 210 and threadedly connected to it. After installation, the base 110 of the handle assembly 100 abuts against one side of the sleeve 300. This solution can be applied to scenarios where the faucet 1 is installed on a countertop. If the mounting hole on the countertop is relatively large, the sleeve 300 can be fitted over the valve body 210, and the base 110 determines whether it is properly installed by abutting against the sleeve 300.

[0100] In summary, the installation process of the faucet 1 in this application is illustrated by the example of a concealed installation in the wall:

[0101] First, the valve assembly 200 and the outlet pipe are concealed in the wall. Most of the valve assembly 200 and the outlet pipe are pre-embedded inside the wall; only the valve core 220 of the valve assembly 200 is exposed, and part of the interface pipe of the outlet pipe is exposed. Then, the outlet nozzle 21 is installed on the outlet pipe. A suitable valve stem sleeve 140 is selected and installed on the valve core 220 according to its exposed dimensions. Specifically, the end of the valve stem sleeve 140 with the interface structure 141 is first fitted onto the valve core 220. Then, a screw is passed through the mounting hole 140a of the valve stem sleeve 140 and fixed to the threaded fixing hole 221 of the valve core 220. At this point, the valve stem sleeve 140 and the valve core 220 are fixed both circumferentially and axially. It should be noted that when fitting the valve stem sleeve 140 onto the valve core 220, the limiting boss 1421 of the valve stem sleeve 140 can be installed at a preset angle. That is, it can be installed according to the rotation direction of the valve core 220 and the orientation of the handle 120. For example, the positioning boss 1421 can be set to face upward, downward, left or right.

[0102] Next, the washer 150 and the pivot portion 124 of the handle 120 are inserted into the shaft hole section 113 from the head of the base 110. The bushing 130 is inserted into the mounting cavity 111 from the bottom of the base 110. The bushing 130 is inserted into the mounting groove 120a and is fixed circumferentially by the positioning boss 1311 and the positioning groove 1211. Then, the screw passes through the through hole 130A of the bushing 130 and the blind hole 120b of the handle 120 in sequence to achieve axial fixation. At this time, under the action of the limiting protrusion 133 of the handle 120, the bushing 130, and the screw, the handle 120, the bushing 130, and the base 110 are relatively fixed axially. Then, the limiting groove 1321 of the bushing 130 is matched and installed with the limiting boss 1421. At this time, the orientation angle of the handle 120 will extend to the preset orientation angle. Next, rotate and tighten the base 110 and the valve body 210, simultaneously causing the bushing 130 and the valve stem sleeve 140 to move relative to each other, allowing the valve stem sleeve 140 to extend into the fixing groove 130a. When the bottom end of the base 110 abuts against the wall, the installation is complete.

[0103] This application improves the fit between the base 110 and the wall after installation by setting valve stem sleeves 140 of different lengths; by setting the handle 120 and bushing 130 to be installed in a unique circumferential orientation and the bushing 130 and valve stem sleeve 140 to be installed in a unique circumferential orientation, the handle 120 can be extended at a predetermined angle, avoiding interference with other components (such as the water outlet 21) during the rotation of the handle 120 after installation.
