Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1

[0022] like Figures 1-2 As shown, a water flow indicator with alarm function according to the first aspect embodiment of the present invention includes a water flow indicator body 102. A housing 103 is fixedly connected to the top of the water flow indicator body 102. A lower base plate 209 is fixedly installed at the bottom of the inner cavity of the housing 103. A rotating rod 200 is rotatably connected to the upper surface of the lower base plate 209. The bottom of the rotating rod 200 extends into the water flow indicator body 102. A fan blade 201 is fixedly connected to the lower end of the outer surface of the rotating rod 200. A baffle 205 is fixedly connected to the upper end of the outer surface of the rotating rod 200. A stabilizing block 203 is fixedly installed on the lower base plate 209. The stabilizing block 203 is installed on one side of the baffle 205. The stabilizing block 203 and the baffle 205 are connected by a spring 204. A rubber pad 207 is fixedly installed on the side of the baffle 205 away from the spring 204.

[0023] In the above embodiments, it should be noted that the surface of the water flow indicator body 102 is made of a hard and wear-resistant material. The interior of the housing 103 is used to house the lower base plate 209 and the device above the lower base plate 209, and also serves to protect the internal structure. The lower base plate 209 is used to support the upper rubber pad 207, stabilizing block 203, and other structures. The fan blade 201 is used to receive the impact of the water flow in the water flow indicator body 102, thereby driving the connected rotating rod 200 to rotate. The rotating rod 200 is used to drive the stop bar 205 to rotate, and the stop bar 205 is used to rotate to the rubber pad 207. On the rubber pad 207, the stabilizing block 203 is used to stabilize the spring 204, and the spring 204 is used to pull the baffle 205, so that when there is no water flow, the baffle 205 and the rubber pad 207 are always kept at a certain distance to avoid accidental collision. When in use, water flows into the water flow indicator body 102. Once the water flow is too large, the water flow will drive the fan blade 201 below the rotating rod 200 to rotate, thereby driving the baffle 205 above the rotating rod 200 to rotate onto the rubber pad 207. The larger the water flow, the greater the pressure of the baffle 205 on the rubber pad 2074.
