When the impeller 210 is impacted by water flow to rotate, the driving gear sets drive the water outlet nozzles 220 installed oppositely at two sides to rotate, and the output port of the first spiral flow channel 115 and the output port of the second spiral flow channel 224 are dislocated and overlapped, so that two different water outlet effects are formed, and a rotating spiral water type with the hole number multiplied geometrically or reduced is formed.

Specifically, as shown in fig. 27, the output port of the first spiral flow channel 115 and the output port of the second spiral flow channel 224 are aligned with each other to form two spiral water flows; as shown in fig. 28, the output port of the first spiral flow channel 115 and the output port of the second spiral flow channel 224 are offset from each other to form four spiral water flows.

In this embodiment, when the water outlet nozzle 220 rotates, the output port of the first spiral flow channel 115 and the output port of the second spiral flow channel 224 intermittently form jet flows with different apertures and hole numbers in a relative rotation manner, and under the same water outlet area, the hole numbers and the aperture are mutually complemented to form spiral water with alternating strength, so that the comfortable experience of the shower of the user is improved.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

Of course, the present utility model is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are included in the scope of the present utility model as defined in the claims.
