[0034] The following will refer to the attached Figures 1 to 7 The present invention is described in detail with reference to embodiments.

[0035] In general, the present invention relates to a faucet structure, comprising a main body pipe 1, a rotating assembly connected to the bottom of the main body pipe 1, a vertical pipe 2 connected to the top of the main body pipe 1, a top pipe 3 connected to the top of the vertical pipe 2, and a flow limiting assembly arranged on the side wall of the vertical pipe 2;

[0036] In this embodiment, the rotating assembly is installed on the sink and connected to the water pipe. It is used to adjust the angle between the main pipe 1 and the sink, reducing the space occupied when installed and transported together with the sink. The main pipe 1 is used to guide water into the vertical pipe 2 and finally into the curved top pipe 3. The flow limiting device can adjust the water flow speed of the vertical pipe 2, thereby controlling the flow speed of the water sprayed from the end of the top pipe 3 to prevent splashing and contaminating the sink countertop.

[0037] Among them, Figure 3 As shown, the current limiting component includes a fixed tube 8, which is fixedly arranged inside the vertical tube 2, and a connecting hole 801 communicating with the lower side of the vertical tube 2 is opened on one side of the fixed tube 8, and a water storage chamber 802 communicating with the connecting hole 801 is opened on the fixed tube 8 on one side of the connecting hole 801, and the water storage chamber 802 is communicated with the upper side of the vertical tube 2, and a rotating cylinder 9 is rotatably arranged in the water storage chamber 802, and the rotating cylinder 9 is communicated with the water storage chamber 802, and openings 901 are opened on two opposite sides of the rotating cylinder 9, and the circumferential side of the rotating cylinder 9 is tightly fitted with the water storage chamber 802; the rotating cylinder 9 rotates to the point where the opening 901 is connected with the water storage chamber 802 and the vertical tube 2, and the rotating cylinder 9 is communicated with the upper side of the vertical tube 2.

[0038] During specific implementation, water flows through the main pipe 1 into the vertical pipe 2 and into the flow limiting component. Specifically, the water flows into the connecting hole 801 from the lower side of the vertical pipe 2 and then into the water storage chamber 802. Since the rotating cylinder 9 has an inner cavity, the water flows into the rotating cylinder 9 from its open mouth. Since the water storage chamber 802 is connected to the upper side of the vertical pipe 2, when the rotating cylinder 9 rotates to the point where the opening 901 is connected to the water storage chamber 802 and the vertical pipe 2, the water flows into the upper side of the vertical rod and finally sprays out in the top pipe 3.

[0039] It should be noted that by adjusting the overlapping area between the opening 901 and the connection point between the water storage chamber 802 and the vertical pipe 2, the flow rate of water entering the top pipe 3 can be controlled, thereby adjusting the flow rate of water sprayed by the top pipe 3.

[0040] In order to facilitate the rotation of the rotating cylinder 9, in this embodiment, a connecting rod 902 is fixedly provided on the side wall of the rotating cylinder 9, and a rectangular fixing rod 903 is fixedly provided at the end of the connecting rod 902. The rotating cylinder 9 is driven to rotate by rotating the fixing rod 903. Further, a rotating shell 10 is inserted and matched on the fixing rod 903, and the connecting rod 902 and the fixing rod 903 are inside the rotating shell 10. The operator controls the rotating cylinder 9 through the rotating shell 10, and the rectangular fixing rod 903 facilitates the rotating shell 10 to drive it to rotate. In specific implementation, the rotating shell 10 is connected to the fixing rod 903 through the fixing part 11, and the fixing part 11 can be a latch, a screw, etc., which is not further limited here.

[0041] In order to increase the sealing performance of the connection between the vertical pipe 2 and the top pipe 3, in this embodiment, Figure 2 As shown, a connecting pipe 7 is provided at the connection between the vertical pipe 2 and the top pipe 3, and the upper and lower ends of the connecting pipe 7 are respectively connected with the top pipe 3 and the vertical pipe 2, and a first sealing ring 701 is sleeved on the peripheral side of the connecting pipe 7, and the first sealing ring 701 abuts against the inner side wall of the top pipe 3. Furthermore, a groove 702 is provided on the peripheral side of the connecting pipe 7 below the first sealing ring 701, and a second sealing ring 703 is provided in the groove 702, and the second sealing ring 703 abuts against the inner side wall of the vertical pipe 2.

[0042] It should be further explained that the position of the first sealing ring 701 can be adjusted according to actual conditions, which can facilitate adjustment of the installation position between the first sealing ring 701 and the top pipe 3.

[0043] like Figures 4 to 7 As shown, the above-mentioned rotating assembly includes a mounting block 4 arranged at the bottom end of the main body tube 1, a mounting groove 401 provided in the mounting block 4, a rotating part 5 rotatably arranged in the mounting groove 401, a water outlet 501 provided on the rotating part 5, and a water inlet pipe 502 arranged in communication with the rotating part 5;

[0044] like Figure 5 As shown, the rotating part 5 is connected to the installation groove 401 through the water outlet 501, a connecting port 403 is provided on the top of the installation block 4, the installation groove 401 is connected to the main pipe 1 through the connecting port 403, and the opening of the installation groove 401 is configured so that the rotating part 5 can rotate to any angle within the range of 0 degrees to 90 degrees.

[0045] In a specific implementation, the rotating part 5 can rotate in the installation groove 401 with the center of the water outlet 501 as the rotation axis. When rotating, the side wall of the rotating part 5 is closely fitted with the inner wall of the installation groove 401. Figure 6As shown, the communication port 403 extends downward to form a groove on the inner wall of the installation groove 401, and the water outlet 501 abuts against the groove to ensure water flow communication during rotation.

[0046] In detail, water flows from the water inlet pipe 502 into the rotating part 5, enters the groove through the water outlet 501, and enters the main pipe 1 along the groove through the connecting port 403. Since the sink and the faucet structure are installed as one, the main pipe 1 can be rotated to be parallel to the sink countertop by rotating the assembly, that is, the main pipe 1 and the water inlet pipe 502 are at the same level, which reduces the occupied space.

[0047] In order to prevent the main pipe 1 from shaking after installation, in the present embodiment, a socket 402 is further provided on the installation, and a sliding column 6 is slidably connected in the socket 402. A spring 601 is mounted on the sliding column 6. One end of the spring 601 is fixedly connected to the inner wall of the socket 402, and the other end is fixedly connected to the sliding column 6. When the water inlet pipe 502 is rotated to be perpendicular to the main pipe 1, the end of the sliding column 6 is inserted into the rotating part 5.

[0048] During specific implementation, the sliding column 6 is pulled up and the spring 601 is compressed. When the main pipe 1 and the water inlet pipe 502 are installed vertically, the sliding column 6 is loosened and its end is inserted into the rotating part 5 to limit the rotating part 5 and fix the position of the main pipe 1. The reset of the spring 601 can drive the end of the sliding column 6 to be in the rotating part 5 to prevent it from falling off.

[0049] As a preferred structure of the present invention, Figure 1 As shown, the two sides of the vertical pipe 2 are connected with a first side pipe 201 and a second side pipe 202, and the first side pipe 201 and the second side pipe 202 are also provided with the above-mentioned flow limiting components. Such a structure can meet the different experimental needs of the operator. In addition, in order to further increase the stability of the water flow spraying, a nozzle 301 is provided at the end of the top pipe 3, the first side pipe 201, and the second side pipe 202.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
