In this embodiment, the operating principle of the nozzle is as follows:

1. as shown in fig. 2, in a natural state, the elastic restoring forces of the second spring 5 and the first spring 9 will interrupt the outward pushing of the valve shaft 2 and the switching valve shaft 6, so that the third port 15 and the first port 17 are opened, and water flows out from the first water outlet 40 through the first water channel 12;

2. as shown in fig. 3, in the water discharge state of the first water channel 12 in fig. 2, when one end of the switching button 30 in the length direction relatively close to the switching valve shaft 6 is pressed, the switching button 30 drives the switching valve shaft 6 to move inward in the radial direction of the water diversion member 1, the first sealing ring 8 closes the first valve port 17, and the second valve port 16 is opened relatively, so that the first water channel 12 is closed, and the second water channel 13 is opened. At this time, since there is still a water pressure influence on the switching valve, even if the switching button 30 is released, the elastic restoring force of the first spring 9 is not enough to move the switching valve shaft 6 outward in the radial direction of the water separator 1, so that the head can be stabilized in the state where water is discharged from the second water outlet 50. At this time, the water outlet state of the first water path 12 is switched to the following two methods:

3.1. as shown in fig. 2, in the water outlet state of the second water channel 13 in fig. 3, when one end of the switching button 30 relatively far from the switching valve shaft 6 in the length direction is pressed, the switching button 30 drives the switching valve shaft 6 to move outward in the radial direction of the water dividing member 1, so that the first valve port 17 is opened, and water flows out from the first water outlet 40 through the first water channel 12;

3.2. referring to fig. 4, in the state that the second water path 13 in fig. 3 is discharging, the pause button 20 is pressed to move the valve shaft 2 inward in the radial direction of the water diversion member 1, the valve shaft 2 is moved to close the second sealing ring 4 to close the third valve port 15, the main water path 11 is closed, the water supply is stopped, the switching valve is not under the water pressure, the valve shaft 6 is moved outward in the radial direction of the water diversion member 1 (i.e. the first sealing ring 8 is moved toward the second valve port 16) under the elastic restoring force of the first spring 9, the first valve port 17 is opened, and the water flows out from the first water outlet 40 through the first water path 12.

As a matter of course, the interruption valve may operate under the condition that water is discharged from the second water outlet 50, or may operate under the condition that water is discharged from the first water outlet 40, so as to suspend water discharge by pressing the suspension button 20, and the interruption valve is controlled to operate by pressing the suspension button 20, and the water discharge size may be adjusted to a certain extent, thereby achieving the effect of saving water.

The novel shower nozzle in this embodiment can conveniently carry out the switching of two kinds of different delivery ports play water through button operation diverter valve, can also pause the play water at any time through the break valve of button operation, convenient to use, simple. More importantly, in this embodiment, by providing the first spring 9 and enabling the first spring 9 to always give the first sealing ring 8 a tendency to move toward the second valve port 16, the novel sprinkler can stop water discharge and the switching valve loses water pressure through the interruption valve, and the first sealing ring 8 leaves the first valve port 17 and closes the second valve port 16 under the action of the first spring 9, so that switching of the waterway is automatically completed, and the sprinkler automatically resets to a small-flow bubbling water waterway after water discharge is stopped, thereby achieving the effect of saving water.
