Give the user a visual experience.

The following describes the specific embodiments.

Implementation of the first one:

As shown in FIG. 1, the body 1 of the water outlet device of the embodiment is provided with an ice path cavity 11 and a circuit cavity 12, and an impeller 2 is disposed in the water channel cavity 11. The water nozzle 3 is integrally formed or separately disposed under the impeller 2, and the water outlet 3 is provided with a slanted water outlet 31, and the water outlet 3 partially protrudes from the 'surface cover of the body 1. 13. The cover 13 of the body 1 has an annular decorative cover 14, and the decorative cover 14 is provided with a plurality of LED lamps 4 surrounding the nozzle 3. The LED 'light 4 is connected to a chip-equipped circuit board 5 via a wire, and the circuit board 5 is disposed in the circuit cavity 12 of the body 1. A coil 61 is further disposed in the circuit cavity 12, and an annular magnet 62 is fixed on the impeller 2. The coil 61 is located in the ring of the magnet 62. The magnet 62 is rotated around the coil 61. The electromotive force thus constitutes a power supply circuit for supplying power to the circuit board 5. The power generation system formed by the coil 61 and the magnet 62 is an alternating current power generation system, and an alternating current is generated, and the chip on the circuit board 5 can measure the alternating current frequency, and then the alternating current frequency is used as a fundamental frequency, and the control circuit outputs a certain value. A rectangular wave of frequency ' is used to open and close. The LED lamp 4 causes the LED lamp 4 to blink.

The working principle of the water outlet device is as follows: after the water flow enters the water passage chamber 11 from the ice inlet of the body 1, the impeller 2 is driven to rotate, and the water nozzle 3 is rotated to rotate, due to the water outlet 31 on the water outlet 3. For tilting, this produces a progressively rotating water spray. At the same time, the magnet 62 also rotates with the impeller 2, causing the magnetic field of the coil 61 to change to generate electric energy. The power supply circuit board 5, the chip on the circuit board 5 measures the frequency of the alternating current generated by the coil 61. Since the rotation speed of the magnet 62, the impeller 2 and the water outlet 3 are the same, the AC frequency is the water outlet 3 Speed. The chip then uses the AC frequency as the base frequency, and the circuit outputs a rectangular wave of a certain frequency for lighting the LED lamp 4 to cause the LED lamp 4 to blink. Since the blinking frequency of the LED lamp .4 is based on the rotation speed of the nozzle 3, when the flashing light is irradiated on the rotating water, a good dynamic effect can be seen.

When the frequency of the rectangular wave outputted by the chip control circuit is the same as the AC frequency, the blinking frequency of the LED lamp 4 is the same as the rotation speed of the nozzle 3. At this time, the LED lamp 4 blinks once every time the water spout 3 rotates, so that the LED lamp 4 just lights up and illuminates the fixed position every time the water per stream ejected from the water outlet 31 reaches a fixed position. The water flow at the location, and the line connecting the fixed bright spots of each water stream form a blinking fixed trajectory, as shown in Fig. 2, which is the divergent single spiral water discharge trajectory formed by the above embodiment.

If the blinking frequency of the LED lamp 4' is not exactly the same as the frequency of the rotating nozzle 3, but is close to each other, the formed water trajectory will jump in a small range. For the above embodiment, the formed divergent single is formed. The rappelling will jump up and down to achieve dynamic water efficiency Embodiment 2:

This embodiment is the same as the main structure of the first embodiment, except that the water outlet of the water outlet is an eccentric vertical water outlet, so that the water flower formed is a vertically rotating water flower. Another difference is that: the frequency of the rectangular wave outputted by the chip control circuit is twice the frequency of the alternating current, so that the blinking frequency of the LED light is twice the rotational speed of the water outlet, that is, the water outlet The LED flashes twice every time the mouth rotates. As shown in Fig. 3, the water discharge trajectory formed by the water outlet device of this structure is a vertical and fixed silent spiral track. If the blinking frequency of the LED lamp is approximately twice the frequency of the nozzle rotation speed, the vertical silent spiral trajectory formed is a dynamic effect. .

It can be seen from the above analysis that the blinking frequency of the LED lamp is always an integer multiple of the frequency of the nozzle rotation speed, or approximately an integer multiple, or 1/n times, or approximately 1/n times, and n is a positive integer. Out of the 'water track. And the higher the multiple, the more the number of spirals forming the water trajectory and the lowering of the flashing frequency of the LED lamp than the rotational speed of the water outlet, the larger the helical moment of the spiral is formed.

Embodiment 3:

As shown in FIG. 4, the water outlet of the water outlet device of the present embodiment is also provided with a water passage cavity 1 and a circuit cavity 12'. The water passage cavity 1 is provided with an impeller 2', and the impeller 2' is decelerated. The mechanism 7' is connected, the speed reduction mechanism 7' is connected to a rotor 3', and the rotor 3' is provided with at least one flap 32'. The waterway cavity 1 is further provided with a partition 15' to divide the waterway cavity 11' into two front and rear chambers, and the partition 15' is provided with the same number of outlet holes 16 as the rotor's baffle 32'. When the rotor 3' is rotated, its blocking piece 32' can continuously resist the corresponding water outlet hole 16' to prevent water from entering the front chamber of the waterway cavity 11' from the water outlet hole 16', and then the cover The outlet on the 13' flows out. The body is also provided with a plurality of LED lights 4' that illuminate the water flow. The LED lamp 4' is connected to a chip-equipped circuit board 5' via a wire, and the circuit board 5' is disposed in the circuit cavity 12" of the body casing, and the circuit board 5' is passed through a power supply circuit (not shown). Power supply, the power circuit can be an internal battery pack or an external power supply. The body cymbal is also provided with a rotational speed measuring device (not shown) that can directly measure the rotational speed of the rotor 3', and transmits the measured rotational speed frequency to the chip on the circuit board 5', and the chip then uses the rotational speed. The frequency is the fundamental frequency, and the control circuit outputs a rectangular wave of a certain frequency to open and close the LED lamp 4', so that the LED lamp 4' blinks.

The working principle of the water outlet device is as follows: the water flows from the water inlet of the body 1' into the rear chamber of the water passage chamber 1 , and the impeller 2' is rotated, and the high speed of the impeller 2' is decelerated by the speed reduction mechanism 7 to drive the rotor. 3' low frequency rotation, so that the piece 32' on the rotor 3' constantly resists the water outlet 16' on the partition 15', so that the water flow will intermittently enter the front chamber of the water passage chamber 1Γ, thus from the cover 13 'The outlet of the outlet is the intermittent water splash. At the same time, the rotational speed measuring device measures the rotational speed of the rotor 3' and transmits it to the chip. The chip then uses the rotational frequency as the fundamental frequency, and the 3⁄4 way outputs a rectangular wave of a certain frequency for lighting the LED. The lamp 4' causes the LED lamp 4' to blink. Since the blinking frequency of the LED lamp 4' is based on the rotation speed of the rotor 3', when the water flow per water flowing out from the water outlet reaches a fixed horizontal position at the same time, the LED lamp 4' just lights up and illuminates the light. The water flow at the location 'This is to see the intermittent water trajectory, and it is not difficult to get'. When the flashing frequency of the LED lamp is larger than the rotor speed, the intermittent trajectory is denser.

In addition, the same as the rotating water trajectory, when the blinking frequency of the LED light is an integral multiple of the rotor rotational speed frequency or 1/n times (n is a positive integer), a static intermittent trajectory is formed; and when the LED light is When the flicker frequency is approximately an integer multiple of the rotor speed frequency or approximately 1/n times (n is a positive integer), a dynamic discontinuous trajectory is formed.
