For specific embodiments of the present utility model, referring to Fig. 1 to Fig. 3, a water-saving bubbler with switchable water volume is composed of a filter screen 1, a water diversion body 2, a water inlet body 4, a switching shaft 6, a rectifier 7 and a housing 9 and so on. the

The filter screen 1 is hemispherical and is provided with a plurality of through holes 11 for dispersing water flow. the

A cylindrical protrusion 21 is arranged in the center of the water diversion body 2 , and a plurality of water diversion ports 22 are arranged along the edge of the protrusion 21 . The inside of the protrusion 21 is provided with an accommodating cavity 23 opening downward, and a downward positioning column 24 is provided at the axis of the accommodating cavity. the

Referring to FIG. 4 , the water inlet body 4 includes a circumferential wall 41 , and the inner bottom of the circumferential wall 41 is provided with a partition 42 , wherein a plurality of through holes 43 are provided on the partition 42 . A first shaft hole 44 is provided in the center of the partition plate 42 , and a stepped hole 45 with an enlarged diameter is provided on the side of the shaft hole 44 facing the water separation body 2 . the

Referring to Fig. 5, the switch shaft 6 is cylindrical, with a small middle part and large ends. The diameter of the middle part 65 is smaller than the diameter of the shaft hole 44 of the dividing plate 42, and a water flow channel is formed between the two. And its upper end is provided with two flanges 61 and 62 surrounding the circumferential wall. The diameter of the flange 61 is greater than the diameter of the shaft hole 44 and less than the diameter of the stepped hole 45, so that the flange 61 can enter the stepped hole 45 to cover and close the switching shaft. The water flow channel between the middle part 65 and the shaft hole 44 . An annular groove 63 is formed between the two flanges. When installed, the sealing ring 3 is clamped in the annular groove 63 and interferes with the inner wall of the stepped hole 45 to fully seal the aforementioned water flow channel. The switching shaft 6 is also provided with an upwardly opening insertion hole 64 , and the spring 5 is positioned in the insertion hole 64 . the

The rectifier 7 is disc-shaped, with multiple concentric rings 71 arranged on it, and a plurality of radial short posts 72 arranged between the rings, and water holes are formed between adjacent short posts. A second shaft hole 73 capable of accommodating the switching shaft 6 is provided in the center of the rectifier. the

The center of the plane filter 8 is provided with a third shaft hole 83 capable of accommodating the switching shaft 6 . the

The surrounding wall of the casing 9 is provided with a plurality of strip-shaped suction holes 91 at intervals, and the center of the bottom plate inside the casing is provided with a fourth shaft hole 93 capable of accommodating the switching shaft 6 . A water outlet 92 is provided on the bottom plate around the shaft hole 93 . the

The use of the present utility model is as follows. In the normal state, it is a water-saving state. At this time, the flange 61 on the switching shaft 6 enters the stepped hole 45, covering and closing the water flow channel between the middle part 65 of the switching shaft and the shaft hole 44, and the sealing ring 3 is located between the inner walls of the stepped hole 45 of the water inlet body 4, and is further sealed so that water flow cannot pass through the first shaft hole 44. The water flowing into the bubbler from the filter screen 1 passes through the water diversion port 22 of the water diversion body 2, flows down through the through hole 43 of the water inlet body 4, and then is rectified by the rectifier 7 and mixed with air to generate air bubbles. After that, it is buffered by the plane filter screen 8, and finally flows out from the water outlet at the bottom of the housing 9. the

When a large flow is required, the switching shaft 6 is pushed upward until the sealing ring 3 touches the inner wall of the protrusion 21 of the water diversion body 2 . At this time, in addition to the same water outlet route as in the water-saving state, the water flow also flows downward from the cavity between the switching shaft 6 and the inner wall of the first shaft hole 44 of the water inlet body 4, and passes through the second shaft hole 73 of the rectifier 7, the filter The third shaft hole 83 of the net 8 and the fourth shaft hole 93 of the housing are water outlet. Due to the addition of one way of water, the water output at this time is large, which can meet the needs of washing vegetables. the

In the state of large flow, due to the upward action of water pressure, the switching shaft 6 overcomes the active force of the spring 5 and is pressed against the inner wall of the protrusion 21 of the water dividing body 2 without falling. When the faucet is turned off, the water pressure is small, and under the reset force of the spring 5, the switching shaft 6 is pushed down and returns to the initial state, and at this time it returns to one way of water outlet. Therefore, the utility model has the advantage of forced water saving . the

The above is only a specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial modification of the utility model by using this concept shall be an act of violating the protection scope of the present utility model . the
