DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] Referring to FIGS. 1 to 15, a water outflow device comprises a shell 1, a movable plate 2, and a driving mechanism 3. The shell 1 is provided with a water outflow part 11. The water outflow part 11 comprises a plurality of water outlets 12, by way of example, arranged in an annular array at intervals. Each of the water outlets 12 comprises a first inner sidewall 13 and a second inner sidewall 14. The second inner sidewall 14 and the first inner sidewall 13 face each other, for example, the second inner sidewall 14 faces an inside of the water outflow part 11, and the first inner sidewall 13 faces an outside of the water outflow part 11. The driving mechanism 3 is connected to the movable plate 2 to drive the movable plate 2 to repeatedly move between a first position and a second position. The movable plate 2 is close to the water outlets 12 in the first position. The movable plate 2 is disposed away from the water outlets 12 in the second position, and a moving direction of the movable plate 2 is, for example, a direction moving up and down. The movable plate 2 is fixedly provided with a plurality of insertion parts 21, by way of example, arranged in an annular array at intervals. Each of the insertion parts 21 comprises a first outer sidewall 22 and a second outer sidewall 23, the second outer sidewall 23 and the first outer sidewall 22 are arranged back to back. Each of the plurality of insertion parts 21 is respectively inserted into each of the plurality of water outlets 12 one by one. When the movable plate 2 is located in a first position which is close to the water outlets 12, along the water flow direction, the lower end of the insertion parts 21 are co-planar with the lower port of the water outlets 12, each of the second inner sidewalls 14 abuts each of the second outer sidewalls 23, or there is only a small gap between each of the second inner sidewalls 14 and each of the second outer sidewalls 23. In each of the water outlets 12, a first water outflow passage 121 is formed between each of the first outer sidewalls 22 and each of the first inner sidewalls 13. The movable plate 2 is located in a second position, which is away from the water outlets 12. The lower end of the insertion parts 21 are retracted in the water outlets 12, a second water outflow passage is formed in each of the water outlets 12, each of the second water outflow passages comprises a rear water outflow passage 122 formed between each of the first outer sidewalls 22 and each of the first inner sidewalls 13, a front water outflow passage 123 is formed by the lower port of each of the water outlets 12, and each of the front water outflow passages 123 is connected to each of the rear water outflow passages 122. When the movable plate 2 is located in the first position which is close to the water outlets 12, and a water outflow from the water outlets 12 forms a first water outflow angle, as illustrated in FIGS. 10, 12 and 13, the first water outflow angle S1 is outward, and the water flow expands outwardly. When the movable plate 2 is located in the second position which is away from the water outlets 12, a water outflow from the water outlets 12 forms a second water outflow angle, as illustrated in FIGS. 11, 14 and 15, since the front water outflow passage 123 is not interfered with by the insertion parts 21, the second water outflow angle S2 is inward, and the water flow is contracted. Further, the second water outflow angle can be outward (while an angle of the second water outflow angle is different from an angle of the first water outflow angle) or can be vertically downward. The movable plate moves repeatedly, the water outflow from the water outlets changes repeatedly from the first water outflow angle S1 (outward) to the second water outflow angle S2 (inward), the outflow water finally forms a stream with its water outflow angle changing intermittently, and forms a spray pattern with a pulsed rhythm, which is a new water spray pattern. On the one hand, compared to the traditional massage water, it can bring a different shower massage experience, the impact frequency is slower, the massage feeling is more obvious for users, and the impact scope is larger. On the other hand, there are more choices according to the shape of the water outflows of massage water. At the same time, there can be different arrangements according to the water outflow part 11; it does not need to be only arranged as a circle, like the arrangement of the traditional massage water.

[0051] An inclination angle of the first inner sidewall 13 relative to a moving direction of the movable plate 2 is 1, for example, 1 is 5-15 degrees, and an inclination angle of the second inner sidewall 14 relative to the moving direction of the movable plate 2 is 1, for example, 1 is 5-15 degrees. When 1<1, the second water outflow angle S2 is inward, with the movable plate 2 moving repeatedly, the water outflow changes repeatedly from the first water outflow angle S1 (outward) to the second water outflow angle S2 (inward). When 1=1, the second water outflow angle S2 is downward, with the movable plate 2 moving repeatedly, the water outflow of the water outlet changes repeatedly from the first water outflow angle S1 (outward) to the second water outflow angle S2 (vertically downward). When 1>1, the second water outflow angle S2 is outward at the angle of (11), with the movable plate 2 moving repeatedly, the water outflow of the water outlet changes repeatedly from 1 angle (outward) to angle (11) (outward). Along the direction of the water outflow, the first inner sidewall 13 and the second inner sidewall 14 cooperate to form a symmetrical trapezoidal structure with a narrow lower end and a wide upper end. An inclination angle of the first outer sidewall 22 relative to the moving direction of the movable plate 2 is 2, and an inclination angle of the second outer sidewall 23 relative to the moving direction of the movable plate 2 is (32. The first outer sidewall 22 and the second outer sidewall 23 cooperate to form a symmetrical trapezoidal structure with a narrow lower end and a wide upper end along the water outflow direction. The first outer sidewall 22 and the first inner sidewall 13 are arranged in parallel at intervals. Moreover, wherein: 1=2, 1=2, further, they can be unequal according to different needs. With this structure, a water outflow angle of the first water outflow passage and a water outflow angle of the second water outflow passage can be precisely controlled, and interference on the movement of the movable plate 2 can be avoided.
