DETAILED DESCRIPTION

[0024] In order to further explain the technical scheme of the utility model, the following specific embodiment is carried out in detail.

[0025] As Figure 1 And Figure 2 The utility model provides a rotatable inductive faucet, including shell body 1, fixedly penetrating the water inlet pipe 4 of the bottom end surface of shell body 1, the water outlet pipe 2 of setting in the front end surface of shell body 1, the front end surface of shell body 1 is fixedly embedded with the infrared sensor 3 located below water outlet pipe 2, rotatably installs the swivel joint 5 in water outlet pipe 2, the upper end portion of L-shaped water inlet pipe 4 passes through water outlet pipe 2 and is connected with swivel joint 5 rotationally, and water inlet pipe 4 is equipped with electromagnetic valve 7, and infrared sensor 3 and electromagnetic valve 7 are electrically connected with control panel 8 in shell body 1,

[0026] In the embodiment, the O type sealing ring 9 of silica gel material is installed on swivel joint 5, and the outer ring of O type sealing ring 9 is attached to the inner ring of water outlet pipe 2, which improves the sealing performance of swivel joint 5 and water outlet pipe 2 through O type sealing ring 9;

[0027] As Figures 3 to 5 The embodiment also includes limit component 6 for providing positioning for swivel joint 5 in water outlet pipe 2, and limit component 6 includes fixed cylinder 61 embedded in the bottom end surface of water outlet pipe 2, threaded seat 62 and sliding ring 63 slidingly installed in fixed cylinder 61, threaded seat 62 and sliding ring 63 can be vertically moved in the up-down direction along the inner side of fixed cylinder 61.

[0028] Fixed ring 64 is fixedly installed on the top of fixed cylinder 61.

[0029] The upper and lower opposite surfaces of the threaded seat 62 and the sliding ring 63 are connected by the spring 68. The top of the sliding ring 63 is fixedly provided with the hollow limiting column 65 which is movably penetrated through the inner side of the fixed ring 64. The upper portion of the hollow limiting column 65 is provided with the clamping ring 66 which is fixedly arranged on the rotary joint 5. The side surface of the clamping ring 66 is provided with a plurality of arc-shaped limiting grooves 67 which correspond to the hollow limiting column 65.

[0030] The threaded column 69 is movably arranged in the threaded seat 62 and is rotatably connected with the fixed cylinder 61. The threaded column 69 can be horizontally rotated in the fixed cylinder 61 to drive the threaded seat 62 to move vertically along the fixed cylinder 61. The lower end of the threaded column 69 is movably penetrated through the bottom end surface of the fixed cylinder 61. The top of the threaded column 69 is movably inserted into the inner side of the hollow limiting column 65 through the spring 68 and the inner ring of the sliding ring 63. The top of the threaded column 69 provides auxiliary positioning for the hollow limiting column 65, thereby further improving the stability of the hollow limiting column 65 during movement.

[0031] The end of the hollow limiting column 65 close to the clamping ring 66 is in a semispherical structure, so that the clamping ring 66 can extrude the hollow limiting column 65 to be separated from the inner side of the arc-shaped limiting groove 67 during rotation.

[0032] The upper end of the threaded column 69 is in a smooth cylindrical structure. The top end surface of the threaded column 69 and the inner side top end surface of the hollow limiting column 65 are provided with a spacing. The spacing is greater than the maximum depth of the inner side of the arc-shaped limiting groove 67, so as to ensure that the upper end of the hollow limiting column 65 will not be blocked by the threaded column 69 before being separated from the inner side of the arc-shaped limiting groove 67.

[0033] The outer diameter of the threaded column 69 is smaller than the inner diameter of the spring 68, so as to facilitate the elastic expansion and contraction of the spring 68 outside the threaded column 69.

[0034] The bottom end surface of the threaded column 69 is provided with the square rod 610 which is concentrically arranged with the threaded column 69. An external hand wheel can be inserted into the square rod 610, so as to facilitate synchronous rotation of the square rod 610 and the threaded column 69 by rotating the hand wheel.

[0035] The bottom end surface of the fixed ring 64 is pasted with the buffer rubber ring 611 which is in close contact with the sliding ring 63. The inner ring of the buffer rubber ring 611 is flush with the inner ring of the fixed ring 64, thereby reducing the impact of the sliding ring 63 on the fixed ring 64 during upward movement.

[0036] Specifically, by connecting the water inlet pipe 4 to an external water source, and connecting the electromagnetic valve 7 and the infrared sensor 3 to an external power source through power lines, when a person is sensed by the infrared sensor 3, a signal is transmitted to the control panel 8, and after processing by the program of the control panel 6, a signal is sent to the electromagnetic valve 7, at which time the electromagnetic valve 7 is opened, and water from the water inlet pipe 7 enters the rotary joint 5 and flows outward through the rotating structure for use by the person, and when the person leaves, this is sensed by the infrared sensor 3, and after processing by the program of the control panel 6, a signal is sent to the electromagnetic valve 7, at which time the electromagnetic valve 7 is closed.

[0037] When the rotary joint 5 needs to be rotated to adjust the angle, the rotary joint can be directly rotated, the rotary joint drives the clamping ring 66 to rotate, the clamping ring 66 drives the arc-shaped limiting groove 67 to rotate, when one arc-shaped limiting groove 67 rotates, the hollow limiting column 65 is pressed to move downward, the hollow limiting column 65 drives the sliding ring 63 to move downward, and the spring 68 is compressed by the pressing of the sliding ring 63, when the clamping ring 66 drives the next arc-shaped limiting groove 67 to rotate to be directly opposite the hollow limiting column 65, the sliding ring 63 and the hollow limiting column 65 are moved upward into the next arc-shaped limiting groove 67 by the elastic force of the spring 68, and the cycle is repeated until the rotary joint 5 is rotated to the corresponding angle, at which time the hollow limiting column 65 enters the corresponding arc-shaped limiting groove 67, and the hollow limiting column 65 strikes the arc-shaped limiting groove 67 when entering the arc-shaped limiting groove 67, to form a slight vibration feedback, to provide clear operation confirmation for the user, and the hollow limiting column 65 cooperates with the arc-shaped limiting groove 67 to provide positioning for the rotary joint 5, to prevent the rotary joint from being randomly rotated.

[0038] When some occasions need more flexible adjustment, such as when there are old people or children in the family members, to prevent the children from randomly rotating the rotary joint 5, the threaded column 69 can be rotated to drive the threaded seat 62 to move upward, the threaded column 62 presses the spring 68 to be elastically compressed, to increase the strength of the spring 68, at which time the hollow limiting column 65 is affected by the increase in the elastic force of the spring 68 to increase the locking strength with the arc-shaped limiting groove 67, the locking strength between the hollow limiting column 65 and the arc-shaped limiting groove 67 is adjusted according to personal preferences, the locking design is more humanized, and the use is more flexible.

[0039] The above is only a preferred example of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
