Please refer to the water outlet device of the exemplary embodiment of the present application shown in Figures 1 to 14b. The embodiment of the present application provides a water outlet device, as shown in Figures 1 to 8, which specifically includes a cover 1, a water inlet plate 2 and a water outlet 3.

As shown in Figures 5-8, the surface cover 1 includes a cover plate 12 with a mounting hole 11; the water inlet plate 2 includes a base plate 21 spaced apart from the cover plate 12, and a water sealing column 22 extending from the base plate 21 and passing through the mounting hole 11; as shown in Figure 3, the water outlet 3 is elastic and passed through the mounting hole 11, and the water outlet 3 includes a tubular barrel 31, one end of the barrel 31 is flush with the plate surface of the cover plate 12 facing the base plate 21, and the other end of the barrel 31 extends to the side of the cover plate 12 facing away from the base plate 21; the water sealing column 22 is inserted into the barrel 31, and the barrel 31 includes a first section 311 close to the base plate 21 and a second section 312 facing away from the base plate 21, and there is a gap between the inner circumference of the first section 311 and the outer circumference of the water sealing column 22, and the inner circumference of the second section 312 is against the outer circumference of the water sealing column 22.

Specifically, the water outlet 3 of the present application is made of elastic material, the barrel 31 of the water outlet 3 passes through the mounting hole 11, the water sealing column 22 is arranged inside the barrel 31, there is a gap between the inner circumference of the first section 311 of the water outlet 3 close to the base plate 21 and the outer circumference of the water sealing column 22, and the inner circumference of the second section 312 of the water outlet 3 facing away from the base plate 21 and the outer circumference of the water sealing column 22 are matched with zero gap. Figure 9a is a schematic diagram of the cross-sectional structure of the water outlet device of Figure 1 when water is flowing out, and the direction of the arrow in Figure 9a indicates the direction of water flow. As shown in FIG. 9a, water flow, especially tiny water flow, flows down toward the second section 312 along the gap between the inner circumference of the first section 311 of the water outlet device of the embodiment of the present application and the outer circumference of the water sealing column 22. At this time, at least a part of the first section 311 and the second section 312 of the water outlet 3 is deformed, so that the gap between the inner circumference of the second section 312 and the outer circumference of the water sealing column 22 changes from zero gap to gap, and the water flow then flows down between the inner circumference of the second section 312 and the outer circumference of the water sealing column 22, and flows toward the bottom of the water outlet 3. When the water inlet stops, as shown in FIG9b , at least a portion of the first section 311 and the second section 312 of the water outlet 3 recovers and deforms again, and the water outlet 3 returns to its original shape. At this time, the inner circumference of the second section 312 of the water outlet 3 facing away from the substrate 21 and the outer circumference of the water sealing column 22 are again matched with zero clearance, thereby realizing the water shut-off action of the water flow channel. Therefore, the water outlet device of the embodiment of the present application can realize the hole and groove design between the water sealing column 22 of the water inlet plate 2 and the water outlet 3, so that the water pressure of the water outlet is optimized, the water outlet can be opened even with a small water pressure, and the function of turning off and stopping the water can be realized.

Furthermore, the specific shape of the gap between the inner circumference of the first section 311 and the outer circumference of the water-sealing column 22 can be reasonably set, for example, the gap between the inner circumference of the first section 311 and the outer circumference of the water-sealing column 22 can be set as a plurality of holes and grooves evenly distributed along the circumference of the cylinder 31, so that water can flow out from each hole and groove, or the gap between the inner circumference of the first section 311 and the outer circumference of the water-sealing column 22 can be set as an annular gap. In addition, the bottom structure of the water outlet 3 can be further set, and a plurality of water outlet holes can be set below the plurality of holes and grooves or the annular gap, so that the water outlet effect of rain water flowing out of the water outlet device can be achieved.

In some exemplary embodiments, as shown in FIGS. 9 a - 9 b , 10 and 14 b , the inner diameter of the first section 311 gradually decreases toward the second section 312 , and the inner diameter of the second section 312 is equal to the minimum inner diameter of the first section 311 .

When the water outlet through hole 321 is provided as a plurality of small through holes, rain water can flow out. When the water outlet through hole 321 is a through hole with a large aperture, ordinary water flows out. The water outlet through hole 321 on the bottom plate 32 has a guiding effect on the water flow of the water outlet device of the present application. The bottom plate 32 and the water sealing column 22 are provided with a gap, so that the water flowing down from the gap between the water sealing column 22 and the water outlet 3 is first collected and concentrated in the gap space, and then flows out from the water outlet through hole 321. Since the water outlet 3 is made of soft rubber material, the gap structure can prevent the water flow from being deformed and squeezed by the soft rubber material and flowing back. Moreover, the gap structure makes the water outlet effect more beautiful and better.

In some exemplary embodiments, as shown in FIGS. 3-5 and 9a-9b, the outer peripheral surface of one end of the water sealing column 22 close to the substrate 21 is recessed inward to form a first guide groove 23. The extension of the first guide groove 23 The direction is the same as the extending direction of the water sealing column 22 .

Specifically, the outer peripheral surface of one end of the water sealing column 22 close to the substrate 21 is recessed inward to form a first guide groove 23, and the incoming water flow can flow downward along the first guide groove 23, so that when the water outlet device of the present application has a smaller water flow rate, the first section 311 and the second section 312 of the water outlet 3 can also be deformed, so that the tiny water flow can be concentrated and guided to flow.

In some exemplary embodiments, as shown in FIGS. 4-5 , a plurality of first guide grooves 23 are provided, and the plurality of first guide grooves 23 are evenly distributed along the circumference of the water sealing column 22 .
