And the water-saving device is started again, the rotating shaft 2 is driven to rotate to drive the cam 3 to rotate, the cam 3 drives the swing arm 21, so that the adjusting piece 5 moves downwards along the injection hole 12, when the cam 3 rotates to the second position, the adjusting piece 5 is positioned at the third position (lower position) of the injection hole 12 to stop, at the moment, after the rotating disc 7 rotates, the flow guide hole 71 is still communicated with the second through hole 62, the cyclone chamber is far away from the water outlet 124, warm water for cleaning is not rotated, and the water outlet 124 jets out the third water type cleaning water. As shown in fig. 15, the third water type is a thin cylindrical shape, which is suitable for the defecation function.

When the torsion spring 22 is tensioned and stored during the downward movement of the adjusting member 5 along the injection hole 12, the torsion spring 22 can return the rod member 5a to the first position (upper position) of the injection hole 12 as the cam 3 rotates.

In conclusion, the spray head 1021 can not generate cutoff in the process of realizing the switching of the spray mode, and the user experience effect is improved.

The rotation shaft 2 is driven to rotate to drive the rotation disc 7 to rotate, and when the diversion hole 71 rotates to a position communicated with the first through hole 61, the rotation is stopped, and at this time, cold water in the housing 1 can be discharged through the drainage flow passage 15.

In some embodiments, the housing 1 further defines a second groove 17 and a second flow channel 18, the second groove 17 is disposed on the outer circumferential surface of the housing 1 and is parallel to the injection hole 12, and an opening of the second groove 17 and the water outlet 124 of the injection hole 12 are located on the same side. A second flow passage 18 is arranged in the housing 1 in a penetrating manner, and the concave cavity 14 is communicated with the bottom of the second groove 17 through the second flow passage 18.

A third through hole 63 communicating with the second flow path 18 penetrates the diverter tray 6 in the axial direction. The deflector hole 71 can rotate with the rotary disk 7 to a position communicating with the third through hole 63.

The sprayer 1021 further includes a nozzle 9 inserted into the second recess 17, the nozzle 9 preferably being a fan nozzle.

The rotating shaft 2 is driven to rotate to drive the rotating disc 7 to rotate, when the diversion hole 71 rotates to a position communicated with the third through hole 63, the rotation stops, and at the moment, the warm water for cleaning in the concave cavity 14 can be conveyed to the nozzle 9 through the second flow passage 18 to be sprayed out. Referring to fig. 16, the nozzle 9 is preferably a fan-shaped nozzle, and the warm water for washing sprayed from the nozzle 9 has a uniform line shape, so that the warm water for washing sprayed from the nozzle can meet other washing requirements of the user. The spray washing water flow rate ejected by the nozzle 9 is high, the nozzle is not easy to block, and the cleaning area can be increased and the cleaning efficiency can be improved by matching the movement of the spray head 1021.

While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
