Referring to fig. 5 and 6, the connecting portion 1 is provided with an annular limiting groove 12, a bottom wall 13 located at the bottom of the limiting groove 12, and a top wall 14 located at the top of the limiting groove 12, the nozzle 2 is provided with a protruding rib 24, and the protruding rib 24 is accommodated in the limiting groove 12. An annular accommodating cavity 4 is formed between the top wall 14 and the convex rib 24, and the movable element 3 is movably accommodated in the annular accommodating cavity 4.

Referring to fig. 5 and 6, the limiting groove 12 has a first outer diameter 121 and a first inner diameter 122 along the radial direction of the connecting portion 1, and the first outer diameter 121 is larger than the first inner diameter 122. The rib 24 has a second inner diameter 242 and a second outer diameter 241 along the radial direction of the connecting portion 1, and the second outer diameter 241 is larger than the second inner diameter 242 and the first inner diameter 122. With this arrangement, at least a part of the bottom wall of the protruding rib 24 is supported by the bottom wall 13 of the limiting groove 12, and the spray head 2 does not fall from the connecting portion 1.

The second outer diameter 241 is smaller than the first outer diameter 121, so that a gap is formed between the outer side wall of the protruding rib 24 and the inner side wall of the limiting groove 12, and the protruding rib 24 can flexibly rotate in the limiting groove 12.

In this embodiment, the second inner diameter 242 of the protruding rib 24 is smaller than the first inner diameter 122 of the limiting groove 12, and in other embodiments, the second inner diameter 242 of the protruding rib 24 is greater than or equal to the first inner diameter 122 of the limiting groove 12.

Referring to fig. 6 and 7, the connecting portion 1 further includes a connecting member 15, an annular limiting wall 151 extending along a radial direction of the connecting portion 1 is disposed at a top of the connecting member 15, and the limiting wall 151 is the top wall 14 of the limiting groove 12. Spacing wall 151 has third internal diameter 1511, third internal diameter 1511 is less than the second external diameter 241 of fin 24, so set up, make the roof of fin 24 by spacing in spacing inslot 12, and make moving part 3 spacing in annular holding chamber 4, most is wrapped up in annular holding chamber 4 the volume of moving part 3, work as after the shower nozzle device leads to water, fin 24 with moving part 3 can not fly out under the impact force effect of water.

In this embodiment, the third inner diameter 1511 is larger than the second inner diameter 242 of the protruding rib 24, so that a gap is formed between the limiting wall 151 and the outer sidewall of the spray head 2, and the friction force generated when the spray head 2 rotates is reduced, so that the spray head 2 rotates more conveniently.

Referring to fig. 4 and 7, a retaining wall 152 extending opposite to the limiting wall 151 is disposed at the bottom of the connecting member 15, and the connecting portion 1 is disposed with a retaining groove 16 for accommodating the retaining wall 152. The connecting member 15 is a plastic member, and when it is installed, the fastening wall 152 is directly pressed into the fastening groove 16 to complete the installation.

Please refer to fig. 4, the height of the limiting groove 12 is slightly higher than the sum of the height of the protruding rib 24 and the diameter of the moving part 3, so that the nozzle 2 is jacked up under the action of water impact force after the nozzle device is filled with water, the top wall of the protruding rib 24 is jacked against the moving part 3, the moving part 3 is jacked against the limiting wall 151 of the connecting part 15, at this time, a gap exists between the bottom wall 13 of the limiting groove 12 and the bottom wall of the protruding rib 24, and when the nozzle 2 rotates, the friction between the bottom wall 13 of the limiting groove 12 and the bottom wall of the protruding rib 24 can be reduced, so that the rotation of the nozzle 2 is smoother.

When the spray head device is filled with water, water flow enters the spray head 2 from the flow channel 11, one part of water is sprayed out from the columnar nozzle 231, the other part of water is sprayed out from the driving nozzle 232 and drives the spray head device to rotate clockwise or anticlockwise, and as the movable element 3 is arranged in the annular accommodating cavity 4 between the top wall of the convex rib 24 and the limiting wall 151, the surface contact between the spray head 2 and the connecting element 15 is changed into point contact between the movable element 3 and the peripheral wall of the annular accommodating cavity 4, the friction force between the spray head 2 and the connecting element 15 is reduced, and the rotation of the spray head 2 is more flexible.

To sum up, the utility model discloses the shower nozzle device is through setting up shower nozzle 2 that can rotate by oneself on connecting portion 1 to set up moving part 3 between shower nozzle 2 and connecting portion 1, make all tableware all can be by accurate washing, shower nozzle 2 also accessible moving part 3 when rotatory reduces and the connecting piece 1 between frictional force simultaneously.
