[0024] Example

[0025] Depend on Figures 1 to 4 As shown, this utility model embodiment provides an automatic spiral water outlet device, including a fixed frame 1, a first motor 2, a water outlet 3, an adjusting plate 4, a second motor 5, a linkage mechanism 6, and a reset mechanism. The fixed frame 1 has a protruding ring 11 at its bottom, and a driven gear 8 is rotatably sleeved on the outer side of the protruding ring 11. The driven gear 8 has a waist-shaped hole 81 and a connecting rod bracket 82, which is fixedly disposed at one end of the waist-shaped hole 81. The first motor 2 is engaged with the lower end of the fixed frame 1, and its output end is connected to a driving gear 21 that meshes with the driven gear 8 to drive the driven gear 8 to rotate. The water outlet 3 can be connected to a water outlet pipe 9 to discharge water; it is connected inside the waist-shaped hole 81 and can rotate on the vertical surface of the driven gear 8. The adjusting plate 4 is slidably connected to the top end of the fixed frame 1. The second motor 5 is engaged with the upper end of the fixed frame 1, and its output end is connected to a cam 51, which can abut against the adjusting plate 4, thereby causing the motor to rotate. The mechanism can drive the adjusting disk 4 to slide downwards; the linkage mechanism 6 is connected to the linkage bracket 82, with one end abutting against the bottom surface of the adjusting disk 4 and the other end connected to the water outlet 3, so that when the adjusting disk 4 slides down, the linkage mechanism 6 can drive the water outlet 3 to deflect radially on the driven gear 8, making the water outlet 3 perpendicular or inclined to the driven gear 8; the reset mechanism is located between the linkage bracket 82 and the linkage mechanism 6. When the adjusting disk 4 slides down, the reset mechanism is compressed, so that when the cam 51 rotates, the reset mechanism can apply an elastic restoring force to the linkage mechanism 6, thereby driving the linkage mechanism to drive the adjusting disk to slide upwards and reset, and the water outlet 3 to rotate and reset.

[0026] In this embodiment, the second motor 5 drives the cam 51 to rotate. The cam 51 can drive the adjusting disk 4 to slide downwards, and then push the water outlet 3 to swing to the left through the linkage mechanism 6. The reset mechanism can push the linkage mechanism 6 upwards, so that the upper end of the linkage mechanism 6 always abuts against the adjusting disk 4. When the cam 51 changes from high to low, it pushes the adjusting disk 4 to slide upwards so that it always abuts against the cam 51, and at the same time drives the water outlet 3 to swing to the right to reset. By controlling the swing angle of the water outlet 3 by driving the cam 51 with the second motor 5, the water outlet 3 can swing to any angle and stay at different angles. When the water outlet 3 is perpendicular to the driven gear 8, a concentrated water column can be achieved. When the water outlet 3 is at an inclined angle, the first motor 2 drives the driven gear 8 to rotate through the driving gear 21, causing the water outlet 3 to rotate synchronously, which can achieve a circular water outlet. When the first motor and the second motor are running simultaneously, a spiral water outlet can be achieved. Through the cooperation of the two motors, a variety of different water outlet methods can be achieved. The device has a simple structure, the two motors operate independently, and by outputting different numbers of pulses to the motors, the water outlet 3 can be tilted at different angles. It has high reliability and low cost.

[0027] Specifically, connecting seats 83 are provided on both sides of the waist-shaped hole 81, and through holes 84 are provided on the connecting seats 83. A rotating rod 31 is connected to the side wall of the water outlet 3, and the water outlet 331 is rotatably connected to the waist-shaped hole 81 through the cooperation of the rotating rod 31 and the through holes 84. A limiting rod 85 is provided between the connecting seats 83 on the side near the connecting rod bracket 91 to limit the water outlet 3. In this embodiment, it is set that when the most convex point of the cam 51 is rotated upward, that is, when the adjusting plate 4 is in the highest position, the side of the water outlet 3 abuts against the limiting rod 85, and the water outlet 3 is perpendicular to the driven gear 8, which is the initial position of the water outlet device.

[0028] Reference Figure 2 and Figure 3 As shown, the top of the connecting rod bracket 81 is provided with a collar 86. The connecting rod mechanism 6 includes a first connecting rod 61 and a second connecting rod 62. The top end of the first connecting rod 61 abuts against the bottom surface of the adjusting plate 4, and the lower end passes through the collar 86 and is hinged to the second connecting rod 62. The lower end of the second connecting rod 62 is hinged to the side wall of the water outlet 3. The reset mechanism is a reset spring 7.

The reset spring 7 is placed inside the collar 86, with one end abutting against the first retaining ring 87 and the other end abutting against the second retaining ring 63.

[0029] Furthermore, the top of the fixing frame 1 is provided with three sliding rings 12, and the top surface of the adjusting plate 4 is provided with three sliding rods 41. The three sliding rods 41 are slidably connected to the three sliding rings 12 respectively, and the top end of one of the sliding rods 41 can extend out of the sliding ring 12 and abut against the cam 51. The adjusting plate 4 slides up and down on the top of the fixing frame 1 through the cooperation of the sliding rings 12 and the sliding rods 41. The upper ends of the other two sliding rings 12 are connected to water pipe fixing parts 91, which can connect the water supply device and the water outlet pipe 94 for water supply. The adjusting plate 4 has a round hole 42 in the middle. The lower end of the water pipe fixing part 9 passes through the top surface of the fixing frame 1 and the round hole 42 in sequence, and connects to the water outlet pipe 9. The lower end of the water outlet pipe 9 is sleeved in the water outlet 3, and the two can slide relative to each other. The water outlet pipe 9 is a flexible hose.

[0030] Reference Figure 2 As shown, a motor bracket 13 is connected to the top surface of the fixed frame 1, and the second motor 5 is connected to the motor bracket 13. A micro switch 52 is connected to the top of the motor bracket 13. The micro switch 52 is provided with an elastic piece 53 that can abut against the cam 51. The micro switch 52 is electrically connected to the second motor 5. The micro switch 52 can sense the rotation of the cam 51 through the elastic piece 53 and control the operation of the second motor 5, thereby controlling the tilt angle of the water outlet 3.
