[0030] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following embodiments are combined with the drawings to specifically describe the utility model. And define Figure 6 The up-down direction shown in the drawing is the up-down direction in the embodiment, and the direction from right to left in the drawing is the front-to-back direction in the embodiment.

[0031] Referring to Figures 1 to 7 The faucet with universal rotating mechanical arm provided by the embodiment includes:

[0032] The connecting pipe 1 extends in a lateral direction to form a connecting portion 3 at each end, and at least one elastic member 7 is embedded on the outer wall of each connecting portion 3.

[0033] Two connector tubes 2 are respectively rotatably fitted around the outer periphery of one of the connecting parts 3. Multiple slots 23 are also arranged circumferentially on the inner wall of the connector tube 2. One end of the elastic member 7 extending out of the connecting part 3 abuts against one of the slots 23 to limit the free rotation of the connector tube 2 and allow the connector tube 2 to rotate under force.

[0034] Furthermore, one of the connector pipes 2 serves as the inlet connector 22 and is rotatably connected to the water supply equipment 6, while the other connector pipe 2 serves as the outlet connector 21 and is connected to the nozzle assembly 4, so that the water flow can sequentially pass through the water supply equipment 6, the inlet connector 22, the connecting pipe 1, the outlet connector 21, and the nozzle assembly 4.

[0035] Based on the above technical solution, the faucet with a omnidirectional rotating robotic arm includes a connecting pipe 1, two connector pipes 2, a nozzle assembly 4, and an elastic component 7. The connector pipe 2 and the connecting pipe 1 are connected by the elastic component 7 to achieve rotation and limit rotation. One of the connecting pipes 1 serves as a water inlet connector 22 and is rotatably connected to the water supply device 6, so that the connecting pipe 1 and the two connector pipes 2 together form an omnidirectional rotating robotic arm. The overall structure is simple, easy to disassemble and assemble, and the rotation is smooth, resulting in a better user experience.

[0036] In a preferred embodiment, specifically as follows: Figures 1 to 3 ,as well as Figure 6 As shown, a retaining ring 5 is also provided between the connector tube 2 and the connecting part 3. The outer periphery of the connecting part 3 forms an annular groove 31. The retaining ring 5 is rotatably fitted into the annular groove 31 and is detachable from the connector tube 2. This allows the retaining ring 5 and the connector tube 2 to rotate circumferentially relative to the connecting part 3, and prevents the retaining ring 5 and the connector tube 2 from coming out of the connecting part 3 in the axial direction.

[0037] As a further preferred embodiment, the retaining ring 5 has a notch on one side to allow it to disengage from the connecting pipe 1 in the radial direction, making disassembly and assembly more convenient. In this embodiment, the retaining ring 5 is designed as a non-integral ring, facilitating disassembly and assembly. Alternatively, the retaining ring 5 could be designed as an integral ring, allowing it to be assembled into or disassembled from the annular groove 31 by pulling or squeezing, and is not limited to this. Furthermore, a limiting post 51 is formed radially on the outer wall of the retaining ring 5. A limiting hole 24, opposite to the limiting post 51, is formed on the peripheral wall of the connector pipe 2, and the limiting post 51 is fitted into the limiting hole 24 to hold the connector pipe 2 and the retaining ring 5. Furthermore, a U-shaped through groove 52 is cut around the limiting post 51 on the outer wall of the retaining ring 5, allowing the limiting post 51 to move radially out of the limiting hole 24 under force and to return to its original position under its own elasticity when no force is applied. However, it is obvious that the connection between the retaining ring 5 and the connector tube 2 can also be achieved by, for example, a retaining block groove 23 structure or a pin insertion hole structure. The solution adopted in this embodiment makes it possible to achieve a structure that is easy to detach from each other without additional parts, but it is not limited to this.

[0038] As a further preferred embodiment, an opening groove 32 is also provided in the annular groove 31 on the outer peripheral wall of the connecting part 3, and when the retaining ring 5 rotates to the position of the opening groove 32, the limiting post 51 is allowed to move radially into the opening groove 32 under the force state, so that the limiting post 51 can disengage from the limiting hole 24 and the connector tube 2 can be axially disengaged from the connector tube 2.

[0039] In a preferred embodiment, the connecting pipe 1 includes a straight handle pipe 11. The upper and lower ends of the straight handle pipe 11 extend in the same direction to form a tubular connecting portion 3. The lower end of the straight handle pipe 11 is open and fitted with a plug 12, while the upper end of the straight handle pipe 11 is closed or connected to an end cap. Specifically, in this embodiment, the plug 12 is glued or ultrasonically welded to the lower end opening of the straight handle pipe 11 to form a non-removable structure suitable for the water pressure inside the straight handle pipe 11. However, it can also be designed as a removable plug for regular cleaning of the pipe, or as a pressure relief plug to maintain water pressure inside the pipe.

[0040] Furthermore, the outer wall of the connecting part 3 is also provided with blind holes 33 for embedding elastic members 7. The elastic members 7 include nested ball pins 72 and springs 71, and the end of the ball pin 72 facing away from the blind hole 33 abuts against the groove 23 of the connector tube 2 and can move in each groove 23. In addition, the two connecting parts 3 can also be arranged on different sides of the straight handle tube 11, and are not limited to this. Furthermore, the connector tube 2 is generally in the shape of an "L"-shaped tube, and is configured as an inlet end and an outlet end. The inlet end of the connector tube 2, which serves as the inlet connector 22, is rotatably connected to the water supply device 6, while the outlet end is rotatably connected to the connecting part 3 located below. The outlet end of the connector tube 2, which serves as the outlet connector 21, is connected to the nozzle assembly 4, while the inlet end is rotatably connected to the connecting part 3 located above. This forms an internal water circuit. In this embodiment, the water supply device 6 is an electric water faucet, but it is obviously applicable to other water supply devices 6.

[0041] In practical applications, the inlet connector 22, connecting pipe 1, and outlet pipe together form a omnidirectionally rotatable robotic arm. One end is rotatably connected to the water supply equipment 6, while the other end is connected to the nozzle assembly 4. The two connector pipes 2 are rotatably connected to the connecting pipe 1 and are internally nested with retaining rings 5. An elastic component 7, consisting of a ball pin 72 and a spring 71, restricts the free rotation of the connector pipes 2 and the connecting pipe 1, but allows them to rotate relative to each other under force. When the user needs to adjust the water outlet direction of the nozzle assembly 4 to any direction, the robotic arm is adjusted in that target direction. The connector pipes 2 and the connecting pipe 1 rotate relative to each other under force, and the ball pin 72 retracts under force, moving from one retaining groove 23 to an adjacent or larger retaining groove 23, and then extending again under the action of the spring 71, abutting against the retaining groove 23. The design of the retaining ring 5 allows the connector pipe 2 to be rotatably assembled onto the connecting part 3 of the connecting pipe 1 without additional accessories, and facilitates disassembly and assembly. Furthermore, multiple sealing rings are provided between the connector tube 2 and the connecting part 3, which is not the main innovation of this solution, so they are omitted here.

[0042] In addition, such as Figure 7 As shown, one end of the inlet connector 22 is rotatably installed in the outlet assembly of the water supply device 6. This is mainly achieved by forming a rotatable insertion hole in the middle of the outlet assembly, which is a common technique in the field and will not be described in detail here. Meanwhile, the connecting pipe 1 can also be designed as a multi-segment nested structure, allowing multiple segments to rotate relative to each other, making the angle adjustment of the nozzle assembly 4 more convenient. The connecting pipe 1 is not limited to a straight pipe; it can be designed as a bent pipe or a corrugated pipe to diversify the angle adjustment methods.

[0043] In a preferred embodiment, specifically as follows: Figure 4 and Figure 5As shown, the nozzle assembly 4 includes an upper cover 41 and a lower cover 42 that are joined together, a nozzle connector 43 and a water path switching component 44 housed inside the upper cover 41 and the lower cover 42. A nozzle sealing ring 45 is also fitted around the outer periphery of the nozzle connector 43. The nozzle sealing ring 45 includes an annular body 46, the outer edge of which has an outwardly expanding annular skirt 47, and the outer edge of the annular skirt 47 abuts against the inner wall of the upper cover 41. This reduces the contact area between the seal and the inner wall of the upper cover 41 of the nozzle assembly 4, and the skirt structure, which expands downwards and outwards, ensures a tight seal, making the rotation of the upper cover 41 smoother and without any obstruction.

[0044] Furthermore, the remaining components in the nozzle assembly 4 are basically the same as those in the existing nozzles that rotate to switch the water outlet direction. They are basically two water channels in the lower cover 42, with water outlet in the middle and water outlet in the outer ring. The water channel switch above can passively switch the liquid flow outlet direction during the rotation of the upper cover 41. The main change in this solution is the sealing structure between the upper cover 41 and the nozzle connector 43. Therefore, the description of its water outlet structure is omitted, but this should not be a reason why it is not feasible.

[0045] As another embodiment, specifically as follows: Figure 7 As shown, it has the same structure as the above, except that the nozzle assembly 4 is a direct injection nozzle, that is, the universal rotating robotic arm in this solution is adapted to various nozzle assemblies 4.

[0046] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
