Description

Technical Field

[0001] This utility model relates to the field of water purifier faucet technology, specifically to a universal robotic arm faucet water purifier. Background Technology

[0002] A faucet is a common term for a water valve, used to control the flow of water. A faucet water purifier, in addition to the water-saving function of a faucet, can also filter raw water, improving water quality. In daily life, we often need faucets that can be adjusted in all directions to supply water in various directions, such as omnidirectional robotic arm faucet water purifiers. Omnidirectional robotic arm faucet water purifiers typically consist of a water purifier body, an omnidirectional robotic arm, and an aerator. The two ends of the omnidirectional robotic arm are rotatably connected to the water purifier body and the aerator, respectively. By rotating the omnidirectional robotic arm, the direction of water flow can be adjusted to meet different needs.

[0003] Currently, when connecting the omnidirectional robotic arm to the water purifier body, the mounting base needs to be connected to the water outlet of the water purifier body using screws, and then the omnidirectional robotic arm is connected to the mounting base using a snap-fit ​​method. When assembling the water purifier body and the mounting base, the screws must first be aligned with the screw holes, the mounting base must be held in place by hand, and then the screws must be tightened with tools. This assembly process is cumbersome and inefficient. Furthermore, when the omnidirectional robotic arm rotates, the screws on the mounting base bear the torque of its circumferential rotation. After prolonged rotation of the omnidirectional robotic arm, the screws are prone to loosening, leading to a poor seal between the mounting base and the water purifier body, and potentially causing leaks. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a universal mechanical arm faucet water purifier that is easy to assemble and can avoid water leakage caused by loose fixing base.

[0005] The technical solution of this utility model is to provide a universal robotic arm faucet water purifier with the following structure: It includes a water purifier body, a universal robotic arm, and an aerator. The two ends of the universal robotic arm are rotatably connected to the water purifier body and the aerator, respectively. The universal robotic arm includes a robotic arm body, an inlet rotating head, an outlet rotating head, and a fixed base. The inlet rotating head and the outlet rotating head are respectively located at both ends of the robotic arm body. A water outlet channel is provided within the robotic arm body, and the water outlet channel connects to the inlet end... The device includes a rotating head and an outlet rotating head. The fixed base has a through hole, and its outer peripheral wall has a radially extending fixing part and a positioning part. The outer edge of the water outlet of the water purifier body has a screw hole corresponding to the fixing part and a positioning groove corresponding to and adapted to the positioning part. The fixing part is connected to the screw hole by a screw, and the positioning part is inserted into the positioning groove. The inlet rotating head is rotatably connected to the fixed base and communicates with the outlet of the water purifier body through the through hole. The outlet rotating head is rotatably connected to the aerator.

[0006] With the above structure, the universal robotic arm faucet water purifier of this utility model has the following advantages compared with the prior art:

[0007] This utility model features a fixing part and a positioning part on a fixed base, and a screw hole and a positioning groove at the water outlet of the water purifier body. When assembling the fixed base, the positioning part is first inserted into the positioning groove, which accurately positions the fixing part and the screw hole. Then, the screw can be directly connected to the screw hole using a tool. Since the positioning part is inserted into the positioning groove, it plays a circumferential limiting role for the fixed base. Therefore, when the universal robotic arm is rotated, the positioning part on the fixed base will bear most of the circumferential rotation torque, thereby preventing the screw from loosening and thus preventing poor sealing between the fixed base and the water purifier body, reducing water leakage.

[0008] Preferably, there are two fixing parts and two positioning parts. The two fixing parts are symmetrically arranged on the outer peripheral wall of the fixing seat in the vertical direction, and the two positioning parts are symmetrically arranged on the outer peripheral wall of the fixing seat in the horizontal direction. This allows for more even force distribution on the fixing seat when the universal robotic arm rotates, avoiding damage to parts caused by excessive localized force.

[0009] Preferably, a first sealing ring is provided at the end of the through hole that connects to the water outlet, and the first sealing ring is tightly fitted to the outer peripheral wall of the water outlet. The first sealing ring can ensure the sealing between the fixing seat and the water outlet, reducing the occurrence of water leakage.

[0010] Preferably, the outer peripheral wall of the inlet rotating head is provided with a first locking ring and a second locking ring spaced apart along its axial direction. The inner peripheral wall of the through hole is provided with a first annular groove and a second annular groove adapted to the first locking ring and the second locking ring. The first locking ring and the second locking ring are respectively locked into the corresponding first annular groove and second annular groove. Through the cooperation of the first locking ring and the second locking ring, the risk of the inlet rotating head falling out of the through hole can be reduced.

[0011] Preferably, the first snap-fit ​​ring is located on the side near the fixed base, and the outer diameter of the first snap-fit ​​ring is smaller than the outer diameter of the second snap-fit ​​ring. This facilitates the assembly of the fixed base and the inlet rotating head by workers.

[0012] Preferably, the outer peripheral wall of the water inlet rotating head is provided with at least one first sealing groove, and a second sealing ring is connected in the first sealing groove. The second sealing ring is tightly fitted with the inner peripheral wall of the through hole of the fixing seat. Multiple second sealing rings can ensure a sealed connection between the water inlet rotating head and the fixing seat, preventing water leakage.

[0013] Preferably, the outer peripheral wall of the water outlet rotating head is provided with a third snap-fit ​​ring and a fourth snap-fit ​​ring spaced apart along its axial direction, and the inner peripheral wall of the aerator connection port is provided with a third annular groove and a fourth annular groove adapted to the third snap-fit ​​ring and the fourth snap-fit ​​ring, and the third snap-fit ​​ring and the fourth snap-fit ​​ring are respectively snapped into the corresponding third annular groove and the fourth annular groove.

[0014] Preferably, the third retaining ring is located on the side near the bubbler, and the outer diameter of the third retaining ring is smaller than the outer diameter of the fourth retaining ring.

[0015] Preferably, the outer peripheral wall of the water outlet rotating head is provided with at least one second sealing groove, and a third sealing ring is connected in the second sealing groove. The third sealing ring is tightly fitted with the inner peripheral wall of the aerator connection port. Attached Figure Description

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown;

[0026] This utility model discloses a universal robotic arm faucet water purifier: including a water purifier body 1, a universal robotic arm 2 and an aerator 3, wherein the two ends of the universal robotic arm 2 are rotatably connected to the water purifier body 1 and the aerator 3 respectively.

[0027] The omnidirectional robotic arm 2 includes a robotic arm body 21, an inlet rotating head 22, an outlet rotating head 23, and a fixed base 24. The inlet rotating head 22 and the outlet rotating head 23 are respectively located at both ends of the robotic arm body 21. The robotic arm body 21 has an outlet channel 211 that connects the inlet rotating head 22 and the outlet rotating head 23. The fixed base 24 has a through hole 243, and its outer peripheral wall has a radially extending fixing part 241 and a positioning part 242. The outer edge of the outlet 11 of the water purifier body 1 has a screw hole 12 corresponding to the fixing part 241 and a positioning groove 13 corresponding to and adapted to the positioning part 242. The fixing part 241 is connected to the screw hole 12 by a screw 14, and the positioning part 242 is inserted into the positioning groove 13.

[0028] The inlet rotating head 22 is rotatably connected to the fixed base 24 and is connected to the outlet of the water purifier body 1 through the through hole 243. The outlet rotating head 23 is rotatably connected to the aerator 3.

[0029] This utility model provides a fixing part 241 and a positioning part 242 on the fixing base 24, and a screw hole 12 and a positioning groove 13 at the water outlet 11 of the water purifier body 1. When assembling the fixing base 24, the positioning part 242 is first inserted into the positioning groove 13, so that the positions of the fixing part 241 and the screw hole 12 can be accurately positioned. Then, the screw 14 can be directly connected to the screw hole 12 with a tool. Since the positioning part 242 is inserted into the positioning groove 13, it will play a circumferential limiting role for the fixing base 24. Therefore, when the universal robotic arm 2 is rotated, the positioning part 242 on the fixing base 24 will bear most of the circumferential rotation torque, thereby preventing the screw 14 from loosening, and thus preventing the fixing base 24 from not sealing tightly with the water purifier body 1, reducing water leakage.

[0030] There are two fixing parts 241 and two positioning parts 242. The two fixing parts 241 are symmetrically arranged on the outer peripheral wall of the fixing base 24 in the vertical direction, and the two positioning parts 242 are symmetrically arranged on the outer peripheral wall of the fixing base 24 in the horizontal direction. This allows the fixing base 24 to be subjected to more even force when rotating the universal robotic arm 2, avoiding damage to parts caused by excessive local force.

[0031] A first sealing ring 244 is provided at one end of the through hole 243 that is connected to the water outlet 11. The first sealing ring 244 is tightly fitted with the outer peripheral wall of the water outlet 11, which can ensure the sealing between the fixing seat 24 and the water outlet 11 and reduce the occurrence of water leakage.

[0032] The outer peripheral wall of the inlet rotating head 22 is provided with a first locking ring 221 and a second locking ring 222 spaced apart along its axial direction. The inner peripheral wall of the through hole 243 is provided with a first annular groove and a second annular groove adapted to the first locking ring 221 and the second locking ring 222. The first locking ring 221 and the second locking ring 222 are respectively locked into the corresponding first annular groove and second annular groove. Through the cooperation of the first locking ring 221 and the second locking ring 222, the risk of the inlet rotating head 22 falling out of the through hole 243 can be reduced.

[0033] The first snap ring 221 is located on the side near the fixed base 24, and the outer diameter of the first snap ring 221 is smaller than the outer diameter of the second snap ring 222. This makes it easier for workers to assemble the fixed base 24 and the water inlet rotating head 22.

[0034] The outer peripheral wall of the water inlet rotating head 22 is provided with two first sealing grooves 223, and a second sealing ring 224 is connected in the first sealing groove 223. The second sealing ring 224 is tightly fitted with the inner peripheral wall of the through hole 243 of the fixed seat 24. Multiple second sealing rings 224 can ensure the sealed connection between the water inlet rotating head 22 and the fixed seat 24, and prevent water leakage.

[0035] Similar to the structure of the inlet rotating head 22, the outlet rotating head 23 has a third retaining ring 231 and a fourth retaining ring 232 spaced apart along its axial direction on its outer peripheral wall. The inner peripheral wall of the aerator 3 connection port has a third annular groove and a fourth annular groove adapted to the third retaining ring 231 and the fourth retaining ring 232, respectively engaging within their corresponding third and fourth annular grooves. The third retaining ring 231 is located near the aerator 3, and its outer diameter is smaller than that of the fourth retaining ring 232. The outer peripheral wall of the outlet rotating head 23 has two second sealing grooves 233, each connected to a third sealing ring 234, which fits tightly against the inner peripheral wall of the aerator 3 connection port.

[0036] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
