Description

Technical Field

[0001] The utility model mainly relates to the technical field of solar water heaters, and specifically relates to a descaling device for a solar water heater. Background Technique

[0002] During the long-term use of a solar water heater, a layer of scale will form on the inner wall of the hot water pipeline. Similar to the reason for scale formation in a kettle for boiling water in daily life, the higher the temperature, the more serious the scaling phenomenon. When taking a bath, the scale particles that fall off flow out along the hot water pipeline, affecting the bathing effect. At the same time, the scale particles that fall off for a long time will gradually accumulate and block the shower head, affecting the use. Currently, a descaling device is used for cleaning, but the existing descaling device has only one cleaning head, and the cleaning effect is not significant enough. Some existing technologies are installed in the water heater, and the descaling device needs to be cleaned regularly, which strengthens the cleaning steps.

[0003] For example, the patent with the application number 201821097767.0 discloses a descaling device for a solar water heater, belonging to the field of daily technology. It includes a hot water pipeline, on which a hot water inlet and a hot water outlet are provided. A conical cylinder with openings at the top and bottom is installed inside the hot water pipeline. A first support rod is evenly installed on the outer wall of the cylinder at intervals. A scraper is installed at the end of the first support rod away from the cylinder, and the scraper abuts against the inner wall of the hot water pipeline. A reinforcing rib is fixedly installed at the top of the cylinder, and the reinforcing rib is connected to a steel wire rope. The steel wire rope passes through a fixed pulley and extends out of the outer wall of the hot water pipeline. The fixed pulley is fixedly installed on the inner wall of the hot water pipeline through a second support rod. A descaling device for a solar water heater of the utility model can remove the scale in the hot water pipeline and prevent the shower head from being blocked.

[0004] The inventor believes that the existing technology has only one cleaning head, and the cleaning effect is not significant enough. Some existing technologies are installed in the water heater, and the descaling device needs to be cleaned regularly, which strengthens the cleaning steps. Content of the Utility Model
