[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5, the present utility model provides a technical solution: a pre-filter with a water leakage prompt, which includes a filter body 1 and a color-changing plate 2. One side of the top of the filter body 1 is fixedly connected with a water inlet pipe 3, and the side of the filter body 1 away from the water inlet pipe 3 is fixedly connected with a water outlet pipe 4. A first bracket 5 is fixedly connected at the middle position of the filter body 1, a collection bin 6 is fixedly connected at the middle position of the first bracket 5, a chute 7 is opened on one inner wall of the collection bin 6, a slider 8 is slidably connected in the chute 7, a buoyancy plate 9 is fixedly connected to one side of the slider 8, an alarm 10 is fixedly connected to the top of the first bracket 5 corresponding to the buoyancy plate 9, a water seepage pipe 11 is fixedly connected to the bottom of the collection bin 6, and second brackets 12 are fixedly connected to both sides of the bottom of the water seepage pipe 11. Installation grooves 13 are opened at the bottoms of the second brackets 12, and extrusion springs 14 are fixedly connected to the inner walls on both sides of the installation grooves 13. Extrusion plates 15 are fixedly connected to the opposite sides of the two extrusion springs 14.

[0019] Both the collection bin 6 and the buoyancy plate 9 are designed in a semi-circular structure. The collection bin 6 is arranged corresponding to the water inlet pipe 3 and the water outlet pipe 4, which is convenient for the collection bin 6 to collect the leaked water. The bottoms of the extrusion plates 15 are both designed in an inclined structure, and the bottom of the water seepage pipe 11 is designed in a concave structure. The color-changing plate 2 is arranged between the two extrusion plates 15, and the color-changing plate 2 is arranged corresponding to the water seepage pipe 11, which is convenient for inserting the color-changing plate 2 upward along the bottom of the extrusion plates 15 for installation. At the same time, the top of the color-changing plate 2 is fitted into the depression at the bottom of the water seepage pipe 11, which is convenient for the transfer of water. The color-changing plate 2 is composed of a substrate and water-sensitive ink, which is convenient for the color-changing plate 2 to display a pattern with a warning reminder function after contacting water.

[0020] Specifically, when using the present utility model, when the connection part between the water pipe and the pre-filter is aged and leaks water, the water seeping out from the connection of the water inlet pipe 3 and the water outlet pipe 4 falls into the collection bin 6. The water in the collection bin 6 flows to the surface of the color-changing plate 2 through the water seepage pipe 11. After the color-changing plate 2 contacts water, the pattern with a warning reminder function on the surface layer is displayed, which plays a reminder and warning role for the maintenance personnel. The maintenance personnel can repair it and replace the color-changing plate 2 at the same time. Just insert the color-changing plate 2 upward along the inclined surface at the bottom of the two extrusion plates 15, and the two extrusion plates 15 squeeze and fix the color-changing plate 2 under the action of the extrusion springs 14. When the seeping water flow is large, it is difficult for the water seepage pipe 11 to drain the water flow from the collection bin 6. The water flow will drive the buoyancy plate 9 to float upward. The floating buoyancy plate 9 floats upward along the chute 7 through the slider 8, and the floating buoyancy plate 9 squeezes the alarm 10. The squeezed alarm 10 emits an alarm to prompt the maintenance personnel to carry out repairs.

[0021] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
