detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

In order to solve the shortcomings of the existing water-saving equipment in the automatic adjustment of flow, the utility model provides a water-saving sheet, as shown in Figure 1, Figure 2, and Figure 3, including a fixed ring 11, a throttle plate 12, a The rubber ring 13 and the fixed ring 11 cover the outer edge of the throttle plate 12. The throttle plate 12 has a number of water holes 121. The flow-limiting rubber ring 13 does not completely cover the water hole 121, and the water flows through the water hole 121. It flows through the throttling piece 12 and the fixing ring 11. A fixed rod 124 is arranged at the center of the throttling plate 12, and the water passage holes 121 are distributed around the fixed rod 124, and the fixed flow-limiting rubber ring 13 is sleeved on the fixed rod. The flow-limiting rubber ring 13 faces the direction of water flow inflow, and the current-limiting rubber ring 13 is impacted by the water flow to form elastic expansion and cover the water hole 121; The larger the diameter is, the larger the area covered by the water hole 121 is, the less water flows through the water hole 121, and the water saving efficiency reaches more than 70%, meeting the requirements of environmental protection and energy saving. The shielding range of the flow-limiting rubber ring 13 to the water hole 121 in the contracted state is smaller than the shielding range of the flow-limiting rubber ring 13 to the water hole 121 in the elastic expansion state.

The utility model performs preliminary flow limitation through the non-completely open throttling piece 12, plus the flow-limiting apron 13 that elastically expands in different degrees according to the water pressure, and the water flow impacts the flow-limiting apron 13, so that the flow-limiting apron 13 13 elastically expands to increase the shielding area of the water hole 121 to realize secondary current limiting and achieve the ultimate goal of water saving. When the water pressure is low, the flow-limiting rubber ring 13 can be close to the contracted state, and the shielding range of the water hole 121 is the smallest, so as to ensure that the water output is properly increased under the low water pressure and the comfort of use is ensured. When the water pressure is high, the flow-limiting rubber ring 13 elastically expands correspondingly according to the water pressure, the shielding range of the water hole 121 is increased, and the water output is appropriately reduced.

As shown in FIG. 4 , an embedding groove 111 is provided on the inner side of the fixing ring 11 , and the outer edge of the throttling piece 12 is embedded in the embedding groove 111 . In order to ensure that the embedding groove 111 fixes and supports the throttling plate 12 , the front wall 112 on one side of the embedding groove 111 facing the direction of water flow is narrower than the rear wall 113 on the other side. When the front wall 112 is relatively narrow, it can also facilitate the installation of the throttle plate 12 . According to implementation requirements, the fixing ring 11 can be made of silicone material, and the soft and elastic silicone material can further facilitate the installation of the throttle plate.

In order to further realize the convenience of assembly of the utility model, the throttling piece 12 and the fixing ring 11 are set as a "fool-proof" structure to prevent wrong installation due to negligence, resulting in poor use effect. As shown in Fig. 5 and Fig. 6, the front side and the rear side of the outer edge of the throttling piece 12 are respectively provided with sunken steps 123 corresponding to the front wall 112 and the rear wall 113 of the insertion groove 111, and the front wall 112 and the rear wall 113 of the insertion groove 111 and The rear wall 113 conforms to the steps 123 on the front side and the rear side of the throttle plate 12 respectively. According to implementation requirements, the throttling piece 12 can be made of hard material by POM to ensure the stability of the throttle piece 12 in the fixing ring 11 .

At the same time, in order to ensure the stability of the installation of the current-limiting rubber ring 13 and the effective shielding of the water hole 121, the throttle plate 12 is provided with a receiving groove 122 along the outer periphery of the fixed rod 124, and the current-limiting rubber ring 13 is placed in the receiving groove. Within 122. The water passage hole 121 is intersected with the groove wall of the accommodation groove 122 , and a part of the water passage hole 121 is opened on the bottom surface of the accommodation groove 122 . When the flow limiting rubber ring 13 expands elastically, it can only cover the part of the water hole 121 located on the bottom surface of the receiving groove 122 , and the part of the water passing hole 121 outside the receiving groove 122 still keeps the water flowing through.

Based on the above-mentioned water-saving sheet 10, the utility model also provides a water-saving hose 20, as shown in Fig. One side is arranged towards the water flow inflow direction.
