[0039] This invention proposes a water outlet device.

[0040] In one embodiment of the present invention, such as Figures 1 to 6As shown, the water outlet device includes: a water outlet body 10, a water outlet pipe 20, an impeller 30, and an elastic reset member 40; the water outlet body 10 is provided with a water passage cavity 11 for connecting to a water source; the water outlet pipe 20 is provided with a water outlet 201 connected to the water passage cavity 11 and is rotatably connected to the water outlet body 10 to have an initial position and a preset position; the impeller 30 is rotatably disposed in the water passage cavity 11 and is driven and connected to the water outlet pipe 20; the elastic reset member 40 is connected between the water outlet body 10 and the water outlet pipe 20, and under the action of the elastic reset member 40, the water outlet pipe 20 has a tendency to reset to the initial position in the preset position; when the water outlet device is turned on, the impeller 30 can rotate under the action of water pressure to drive the water outlet pipe 20 to rotate to the preset position.

[0041] In the technical solution of this invention, when the water outlet device is turned on, water flows from the water passage chamber 11 into the water outlet pipe 20, and the impeller 30 is driven by the water flow. At this time, the impeller 30 drives the water outlet pipe 20 to rotate, and the water outlet pipe 20 rotates from the initial position to the preset position. After the water outlet device is turned off, the water pressure gradually decreases, so the water pressure used to power the impeller 30 to rotate gradually decreases. At this time, the rotational force provided by the elastic reset member 40 to the water outlet pipe 20 is greater than the driving force provided by the impeller 30 to the water outlet pipe 20. Therefore, the elastic reset member 40 can drive the water outlet pipe 20 to rotate back from the preset position to the initial position. This setting can ensure that the water outlet pipe 20 can automatically reset after the water is used up, thus improving the user experience.

[0042] In one embodiment, a rotating drum 21 is provided at the end of the water outlet pipe 20 away from the water outlet 201. The rotating drum 21 is provided with an inlet 211 that communicates with the water outlet 201. The rotating drum 21 is rotatably inserted into the water passage cavity 11. The inlet 211 communicates with the water passage cavity 11. The impeller 30 is driven and connected to the rotating drum 21.

[0043] Specifically, the impeller 30, driven by the water flow, drives the rotating drum 21 to rotate. The rotating drum 21 then drives the entire outlet pipe 20 to rotate. The rotating drum 21 has an inlet 211 on the side facing the water passage cavity 11. Inserting the rotating drum 21 into the water passage cavity 11 reduces the overall volume of the water outlet device. This arrangement reduces the space occupied by the water outlet device and shortens the distance between the outlet pipe 20 and the main body 10, thus accelerating the flow of water through the rotating drum 21 into the outlet pipe 20 and improving water output efficiency. In some other embodiments, the rotating drum 21 has an inlet 211 on its side wall.

[0044] In one embodiment, the elastic reset member 40 is configured as a torsion spring, which is sleeved on the rotating drum 21, with one end of the torsion spring inserted into the rotating drum 21 and the other end inserted into the water outlet body 10.

[0045] Specifically, the torsion spring has greater elasticity and more stable force. When the water outlet device is closed, the water outlet pipe 20 is in the initial position, and the torsion spring is in a relaxed state. After the water outlet device is opened, the water outlet pipe 20 rotates to the preset position. At this time, the torsion spring is in a torsional state and can provide the driving force for the water outlet pipe 20 to rotate from the preset position to the initial position. When the water outlet device is closed, the torsion spring can reset the water outlet pipe 20 to the initial position. This setting drives the water outlet pipe 20 to reset through the force of the torsion spring itself, without the need for additional driving force for reset, making the structure simpler and the drive more stable. In some other embodiments, the elastic reset member 40 is configured as a coil spring, with one end of the coil spring inserted into the rotating drum 21 and the other end inserted into the water outlet body 10.

[0046] In one embodiment, the rotating drum 21 is provided with a protrusion 22, which extends along the axial direction of the rotating drum 21. The protrusion 22 is provided with friction teeth. The impeller 30 is sleeved on the protrusion 22. The water outlet device also includes a screw, which passes through the impeller 30 and is screwed to the protrusion 22 to fix the impeller 30 to the protrusion 22.

[0047] Specifically, the impeller 30 is sleeved on the protrusion 22. The friction teeth on the protrusion 22 increase the friction between the protrusion 22 and the impeller 30. The impeller 30 and the protrusion 22 are further fixed together by screws. This arrangement increases the connection stability between the impeller 30 and the protrusion 22, reducing slippage between the impeller 30 and the protrusion 22 during rotation, thereby improving the stability of the impeller 30 driving the water outlet pipe 20. In some other embodiments, the impeller 30 is sleeved on the rotating drum 21.

[0048] In one embodiment, the impeller 30 is configured as an open impeller.

[0049] Specifically, open impellers transfer liquids at a faster speed. An open impeller includes a central rotating shaft and multiple blades located on the outer periphery of the rotating shaft. Gaps are provided between any two adjacent blades, allowing water to flow through these gaps to the inlet 211 of the rotating drum 21 during rotation. This configuration ensures both the flow rate and the rotational speed of the rotating drum 21. In other embodiments, the impeller 30 is configured as a semi-enclosed impeller.

[0050] In one embodiment, the outer periphery of the protruding post 22 is also provided with a plurality of ribs 23, all of which are connected to the inner wall of the rotating cylinder 21, and the plurality of ribs 23 are evenly distributed at intervals on the outer periphery of the protruding post 22.

[0051] Specifically, the outer periphery of the protruding post 22 is provided with multiple ribs 23, and the protruding post 22 is connected to the inner wall of the rotating cylinder 21 through the multiple ribs 23. This arrangement can increase the connection stability between the protruding post 22 and the rotating cylinder 21. In some other embodiments, the outer periphery of the protruding post 22 is also provided with a rib 23.

[0052] In one embodiment, the circumferential wall of the rotating drum 21 is provided with a positioning groove 212, and the water outlet body 10 is provided with a positioning part 14. The positioning part 14 is slidably connected to the positioning groove 212. In the initial position and the preset position, the positioning part 14 abuts against the two groove walls of the positioning groove 212 that are opposite to each other in the circumferential direction.

[0053] Specifically, the positioning part 14 can slide within the positioning groove 212, and the water outlet pipe 20 will rotate relative to the water outlet body. The sliding range of the positioning part 14 is the range of angles that the water outlet pipe 20 can rotate, that is, the water outlet pipe 20 has a certain rotation area. This arrangement facilitates the connection between the water outlet body 10 and the water outlet pipe 20, and can play a foolproof role during assembly, prompting the assembly personnel to snap the positioning part 14 into the positioning groove 212. In some other embodiments, the peripheral wall of the rotating cylinder 21 is provided with the positioning part 14, and the inner wall of the water outlet body 10 is provided with the positioning groove 212.

[0054] In one embodiment, the peripheral wall of the water passage cavity 11 is provided with a threaded hole, and the positioning part 14 is configured as a screw structure. The positioning part 14 passes through the threaded hole, the head of the positioning part 14 abuts against the outer wall of the water passage cavity 11, and the tail is slidably connected to the positioning groove 212.

[0055] Specifically, the outer peripheral wall of the positioning part 14 is provided with threads, the positioning part 14 is screwed into the threaded hole, the tail of the positioning part 14 passes through the threaded hole and extends into the positioning groove 212, and the tail of the positioning part 14 can abut against the two groove walls of the positioning groove 212 in the circumferential direction to prevent the positioning part 14 from disengaging from the positioning groove 212 during the sliding process. After the positioning part 14 is removed, the water outlet pipe 20 can be separated from the water outlet body 10. This arrangement makes it convenient to disassemble the water outlet body 10 and the water outlet pipe 20 for separate maintenance.

[0056] In one embodiment, the water outlet device further includes a sealing ring 50, which is sleeved on the outside of the rotating drum 21 so that the rotating drum 21 is sealed and fitted into the water passage cavity 11.

[0057] Specifically, the sealing ring 50 is sleeved on the outside of the rotating drum 21, and in the axial direction of the rotating drum 21, the sealing ring 50 is located between the impeller 30 and the elastic reset member 40. In this configuration, the sealing ring 50 can prevent water from flowing to the elastic reset member 40, thereby preventing the elastic reset member 40 from being affected by water and thus preventing water from flowing out from the gap between the water outlet pipe 20 and the water outlet body 10.

[0058] In one embodiment, a handle 12 is provided on the side of the water outlet body 10. In the initial position, the handle 12 and the water outlet pipe 20 are located on opposite sides of the water outlet body 10.

[0059] Specifically, the water outlet body 10 is equipped with a valve 13 for controlling the opening and closing of the water passage chamber 11. A handle 12 is driven by this valve 13, meaning that the opening or closing of the water passage chamber 11 can be controlled by swinging the handle 12. In this embodiment, the handle 12 is positioned in the lateral direction of the water outlet body 10 and is located away from the rotation area of ​​the water outlet pipe 20. This prevents interference between the user's hand and the rotating water outlet pipe 20 when controlling the handle 12, and further reduces the longitudinal space required for the installation of the water outlet device. It only requires lateral space for installation, reducing the longitudinal distance between the edge of the water receiving pool and the water outlet device, thereby improving the user experience. In other embodiments, the handle 12 is located closer to the rotation area of ​​the water outlet pipe 20.

[0060] In one embodiment, the water outlet device further includes a valve stem 60, which is movably disposed at the water outlet 201 and can open or close the water outlet 201. In a preset position, the valve stem 60 can be in the position of opening the water outlet 201 under the action of the water pressure at the water outlet 201.

[0061] Specifically, the valve stem 60 can move up and down at the outlet 201. When the water pressure at the outlet 201 is low or nonexistent, the valve stem 60 moves towards the outlet 201 to close it. When the water pressure at the outlet 201 is high, the valve stem 60 moves away from the outlet 201 to open it. This design facilitates the opening and closing of the outlet 201 and ensures its sealing performance when there is no water flow, thereby reducing the possibility of leakage from the outlet pipe 20. In this embodiment, the water pressure at the outlet 201 only rises to a level sufficient to move the valve stem 60 to open the outlet 201 when the outlet pipe 20 is rotated to a preset position. That is, the outlet 201 will only open after the outlet pipe 20 has been rotated to its designated position, preventing water from flowing out of the water tank and improving the user experience. In some other embodiments, the water outlet device also includes a rotating blade, which is rotatably mounted on the water outlet pipe 20 and is used to cover the water outlet 201. The rotating blade can be manually adjusted to open or close the water outlet 201.

[0062] In one embodiment, the water outlet device further includes an adjusting sleeve 70, which is connected to the end of the water outlet pipe 20. The adjusting sleeve 70 is provided with a sliding hole 71 and a drain hole 72 relative to the water outlet 201. One end of the valve stem 60 is movably abutted against the water outlet 201, and the other end is movably inserted into the sliding hole 71. An adjusting spring 73 is provided between the valve stem 60 and the adjusting sleeve 70. Under the action of the adjusting spring 73, the valve stem 60 can be maintained at the position of abutting against the water outlet 201.

[0063] Specifically, the adjusting spring 73 provides pressure to press one end of the valve stem 60 against the outlet 201. When the water pressure in the outlet 201 is greater than the pressure provided by the adjusting spring 73, the water flow can push the valve stem 60 downward and flow into the drain hole 72 to discharge the water. A waterproof rubber ring 61 is fitted on the end of the valve stem 60 near the outlet 201, and the waterproof rubber ring 61 is located between the valve stem 60 and the outlet 201. This arrangement can further increase the sealing performance at the outlet 201, thereby reducing the occurrence of water leakage in the outlet pipe 20. At the same time, when the adjusting spring 73 deforms and cannot provide such a large pressure, the pressure provided by the adjusting spring 73 can be increased by tightening the adjusting sleeve 70, thereby ensuring the pressure of the adjusting spring 73. In some other embodiments, one end of the adjusting spring 73 is connected to the outlet pipe 20 and the other end is connected to the valve stem 60. The adjusting spring 73 is located inside the outlet 201 and can provide a pulling force to tighten the valve stem 60, giving the valve stem 60 a tendency to move toward the outlet 201.

[0064] In one embodiment, the adjusting sleeve 70 is screwed onto the water outlet pipe 20.

[0065] Specifically, the end of the water outlet pipe 20 has a hollow sleeve 24 protruding outwards. The outer surface of the hollow sleeve 24 has partial threads, and the adjusting sleeve 70 has internal threads. The unthreaded end of the hollow sleeve 24 is connected to the water outlet 201, and the other end is screwed to the adjusting sleeve 70. This arrangement facilitates adjusting the pressure of the adjusting spring 73 by tightening and loosening the adjusting sleeve 70; and controls the water outlet 201 to a relatively high water pressure, preventing water from leaking to the outside of the water receiving tank due to insufficient water pressure. During the tightening of the adjusting spring 73, the water pressure gradually increases, and during the loosening of the adjusting spring 73, the water pressure gradually decreases, thus meeting the water usage requirements of various pressure environments. In some other embodiments, the inner surface of the hollow sleeve 24 has threads, the outer surface of the adjusting sleeve 70 has threads, and the adjusting sleeve 70 is screwed to the hollow sleeve 24.

[0066] This invention also proposes a water supply system, which includes a water outlet device. The specific structure of the water outlet device is as described in the above embodiments. Since this water supply system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. The water supply system includes a kitchen water inlet and a sink. The water outlet device is installed on the edge of the sink in the kitchen. When water needs to be dispensed, there is no need to manually turn the water outlet pipe 20 towards the user. The user only needs to turn the handle 12, and the water outlet pipe 20 will automatically rotate to the side facing the user and then dispense water. When the user returns the handle 12 to its original position, the water outlet pipe 20 will automatically return to its original position, improving convenience and user experience.
