[0040] See also Figure 1 -to Fig.14A multifunctional spray device includes a main body 10 and a first spray assembly 20. The first spray assembly 20 is connected to the main body 10 and is provided with at least two nozzles 30. The nozzles 30 are arranged to swing in a set direction relative to the main body 10. The first spray assembly 20 is also provided with a linkage plate 40 that can move along a set direction. The linkage plate 40 is relatively fixed to at least two nozzles 30. When any nozzle 30 is swung to adjust the water outlet angle, the linkage plate 40 moves along the set direction and drives the other nozzles 30 connected to the linkage plate 40 to swing to achieve synchronous adjustment of the water outlet angle. Alternatively, the linkage plate 40 is directly controlled to move along the set direction to drive the nozzles 30 connected thereto to swing to achieve synchronous adjustment of the water outlet angle.

[0041] The main body 10 is also provided with a spray chamber 11, and the side wall of the spray chamber 11 is provided with at least two mounting grooves 12, which are connected to the spray chamber 11 and have an opening, and the opening is located at the side of the main body 10. The nozzle 30 is installed in the corresponding mounting groove 12, and the size of the mounting groove 12 is set to allow the nozzle 30 to rotate therein. The first spray assembly 20 also includes a clamping member 50, which is covered outside the mounting groove 12 and is provided with a clearance hole 51 for the nozzle 30 to pass through, and the shape of the clearance hole 51 is set to limit the rotation direction of the nozzle 30, so that the nozzle 30 can only swing in the set direction. The clamping member 50 is relatively fixed to the main body 10 and can be locked by screws.

[0042] Specifically, at least one guide groove 13 is provided on the side wall of the installation groove 12, and the guide groove 13 extends in a vertical setting direction. The nozzle 30 is provided with a spherical portion 31 and a spray portion 32. The spherical portion 31 is embedded in the installation groove 12 and is provided with at least one stopper 33. The stopper 33 is a structure that is convex relative to the spherical portion 31, and the stopper 33 can be slidably embedded in the corresponding guide groove 13.

The connecting part 34 can be a protrusion, and the linkage plate 40 is correspondingly provided with a recess, and relative fixation is achieved by embedding the protrusion into the recess. The connection method between the injection part 32 and the linkage plate 40 is not limited to this, and can also be achieved in a common way of gas. When the injection part 32 is controlled to swing along the set direction, the spherical part 31 rotates in the mounting groove 12, and its limiter 33 slides along the guide groove 13, and the protrusion drives the linkage plate 40 to move along the set direction. The injection part 32 is flat relative to the spherical part 31. By adjusting the size of the clearance hole 51 in the set direction or adjusting the size of the guide groove 13 in the vertical set direction, the maximum swing angle of the injection part 32, that is, the maximum angle of the nozzle 30, can be adjusted.

[0044] Further, the linkage plate 40 is located on the side of the pressing member 50 facing away from the installation slot 12, and the linkage plate 40 and the pressing member 50 are in sliding cooperation. At least one guide bar 52 is provided on the side of the pressing member 50 facing away from the installation slot 12, and the guide bar 52 extends along a set direction. The linkage plate 40 and the guide bar 52 are in sliding cooperation, and a convex strip or a sliding groove may be provided on the linkage plate 40 to slide with the guide bar 52, so that the linkage plate 40 slides along the guide bar 52.

[0045] The nozzle 30 of the utility model can also achieve the water discharge effect of swinging water splashes. A through jet channel 35 is provided in the nozzle 30. An oscillating member 36 is also provided at the water inlet end of the jet channel 35. The oscillating member 36 is provided to divide the input water flow into two paths and then converge to form a vortex. A first guide surface 37 is also provided near the side wall of the water outlet end of the jet channel 35. The first guide surface 37 is used to guide the vortex to change direction. The first guide surface 37 is an inclined surface or an arc surface or a step surface. The arc surface guides the vortex to exceed the arc surface opposite thereto. A second guide surface 38 is also provided on the side wall of the water outlet end of the jet channel 35. The second guide surface 38 is used to guide the vortex to change direction again and then spray out. The second guide surface 38 is an inclined surface or an arc surface. In actual applications, the extension direction of the first guide surface 37 and the second guide surface 38 can be adjusted according to actual needs.

[0046] Specifically, the oscillating member 36 is detachably connected to the injection channel 35, the oscillating member 36 is located at the center of the injection channel 35 in the radial direction, there is a gap between the outer periphery of the oscillating member 36 and the inner wall of the injection channel 35, and a third guide surface 39 is provided on the side of the oscillating member 36 opposite to the water outlet of the injection channel 35, and the third guide surface 39 is used to guide the water flow to converge into a vortex. The third guide surface 39 is an inclined surface or a curved surface.

The second guide surface 38 extends radially inwardly and the third guide surface 39 extends radially outwardly and in opposite directions. When the water flow enters the injection channel 35, the water flow meets the oscillating member 36 to form two water flows. The two water flows meet under the guidance of the third guide surface 39 to form intermittent vortices. Driven by the continuous influx of water flow, the vortices are thrown along the second guide surface 38 to the opposite third guide surface 39, and then thrown outward. In this way, a swinging water splash is formed.
