Please refer to Figures 7 to 11, and the implementation is as follows:

The seventh figure shows the water outlet closed state of the present invention, press the pressing member 31 to link the movable valve rod 4, push the push portion 347 to adjust the rotation control portion 34, and rotate the rotary control portion 34 to make the positioning portion 312 correspond to Enter into the groove 341 , and then release the pressing member 31 to link the movable valve rod 4 so that the second end 42 of the movable valve rod 4 closes the channel 231 , thereby closing the water flow from the first chamber 211 to the second chamber 232 .

In the present embodiment, the opening water volume can be divided into four stages of continuous opening of the water volume. The eighth figure shows the quantitative water outlet state of the first stage of water volume continuously opening. The user presses the pressing member 31 to link the activity according to the required water volume. valve stem 4, the second end 42 of the movable valve stem 4 leaves the channel 231, and the water in the first chamber 211 is opened to flow to the second chamber 232, and the pressing member 31 is pressed to link the movable valve stem 4, pushing the pusher part 347 to adjust the rotation control part 34 so that the positioning part 312 of the pressing part 31 is corresponding to the first step part 342. At this time, the assembly end 311 of the pressing part 31 is held by the movable valve stem 4 to the first step part 342. Axial displacement backward, the second end 42 of the movable valve rod 4 gradually leaves the channel 231, the pressing member 31 is released, the spring 45 of the movable valve rod 4 slightly pulls the movable valve rod 4 forward, and the positioning portion 312 abuts against At the first step portion 342, the turning control portion 34 is temporarily positioned, and at this time, the first step portion 342 of the turning control portion 34 separates the assembly end 311 of the pressing portion 31 by a slight distance, because the positioning portion 312 abuts against the first step There is a slight distance between the assembly end 311 of the pressing part 31 and the timing control part 34, and the second end 42 of the movable valve rod 4 slightly opens the channel 231 for the first small amount of water to flow from the first chamber 211 to the The water from the second chamber 232 is quantitatively discharged, and finally the water from the second chamber 232 is sprayed by the sprinkler head 23. Continue, and again, taking the ninth figure as an example, the positioning of the continuous opening of the second water volume is the same as that of the first water volume. For the setting operation, press and hold the pressing member 31 to link the movable valve stem 4, and push the push portion 347 to adjust the rotation control portion 34 so that the positioning portion 312 corresponds to the second step portion 343.

The terminals 311 are separated by a large distance, and at this time, the water passage space can be enlarged, so as to increase the flow rate of fluid that can pass through in unit time, in order to open the quantity of water flowing from the first chamber 211 to the second chamber 232 in the second stage. The water is discharged, and finally the water in the second chamber 232 is sprayed out by the sprinkler head 23; Continue, the tenth figure shows the positioning of the third stage of water volume opening, which is the same as the setting operation of the second stage of water volume. Press and hold the pressing member 31 to link the activity The valve stem 4 pushes the push portion 347 to adjust the rotation control portion 34 so that the positioning portion 312 corresponds to the third step portion 344 . At this time, the assembly end 311 of the push member 31 closes the movable valve stem. 4 is displaced axially backwards, and the second end 42 of the movable valve rod 4 is farther away from the channel 231. Release the pressing member 31 to link the spring 45 of the movable valve rod 4 to pull the movable valve rod 4 forward slightly. The positioning portion 312 abuts on the third step portion 34 and the turning control portion 34 is temporarily positioned still. At this time, the third step portion 344 of the turning control portion 34 connects the assembly end 311 of the pressing portion 31 . It is separated from the pipe body 21 by a large distance, and at this time, in order to increase the water passage space to increase the flow rate of fluid that can be passed per unit time, open the third stage with a large amount of water flowing from the first chamber 211 to the second chamber 232 Finally, the water in the second chamber 232 is sprayed out by the sprinkler head 23; again, the eleventh figure shows the positioning of the fourth stage of water volume opening, which is the same as the setting operation of the third stage of water volume, press and hold the pressing piece 31 is linked to the movable valve stem 4, and pushes the push portion 347 to adjust the rotation control portion 34 so that the positioning portion 312 corresponds to the fourth step portion 345. At this time, the assembly end 311 of the push member 31 moves the The valve stem 4 is displaced axially backward, and the pressing member 31 is released to link the spring 45 of the movable valve stem 4 to pull the movable valve stem 4 forward slightly, and the positioning portion 312 abuts against the fourth step portion 345 , and the control portion 34 At this time, because the fourth step portion 345 separates the assembly end 311 of the pressing portion 31 from the pipe body 21 by a larger distance, the second end 42 of the movable valve rod 4 is further away from the channel 231, and the The second end 42 of the movable valve rod 4 is farther away from the channel 231 to increase the water passage space, so as to increase the fluid flow rate that can be passed per unit time, and open the fourth section of super large water flow from the first chamber 211 to the second chamber 232 Quantitative amount of water is discharged, and finally the water in the second chamber 232 is sprayed out by the spray head 23 .

To sum up, this work has indeed achieved a breakthrough structural design, and has improved creative content, and at the same time can achieve industrial utilization and progress, and this work has not been seen in any publications, and it is also novel.
