[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides an automatic water replenishing device for a hot water system, including a boiler 1.

At the bottom end of the water replenishing pipe 3, there is a rubber ring 505, which is convenient for supporting and guiding the floating ball 4. Here, the buoyancy of the floating ball 4 is relatively large, and under the influence of the water level, the floating ball 4 can be closely sealed with the water replenishing pipe 3.

[0026] In the middle of the guide pipe 6, there is a fixed box 7, and the fixed box 7 is sleeved outside the spiral pipe 8, which is convenient for protecting and insulating the spiral pipe 8 and facilitating the use of the spiral pipe 8 to cool down the guide pipe 6.

[0027] The water inlet of the spiral pipe 8 is provided with a water inlet pipe 10, and the water outlet of the spiral pipe 8 is provided with a water delivery pipe 11. One end of the water inlet pipe 10 penetrates through the fixed box 7 and extends to the outside of the fixed box 7.

Then, control the heating rod 15 to work to fully heat the water body inside the boiler 1. Conduct drainage operation through the liquid outlet pipe 13. At the same time, the generated steam can enter the inside of the guide pipe 6 through the gas collecting hood 9 and the gas outlet pipe 21. Through the cooling spiral pipe 8, the high-temperature water vapor can be quickly cooled and condensed into water droplets and enter the water replenishing bucket 2 again, which can realize the recycling of water resources and reduce the consumption of water resources;

[0033] When the water level inside the boiler 1 drops, under the action of the guide rod 502 by the float ball 4, the float ball 4 drops, causing the float ball 4 and the water replenishing pipe 3 to separate from each other. The water inside the water replenishing bucket 2 automatically replenishes the water inside the boiler 1. When replenishing water, the water level rises again, driving the float ball 4 to rise. After the water replenishment ends, at this time, the float ball 4 and the water replenishing pipe 3 are hermetically sealed with each other, realizing automatic water replenishment for the boiler 1. Finally, the water inside the boiler 1 can be used.
