[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-6 As shown, an easy-to-clean electric water heater includes a water heater 1. The inner side of the water heater 1 is provided with a cleaning structure 2. The cleaning structure 2 includes a top cover 201, which covers the top side of the water heater 1. A drive block 202 is rotatably connected to the top cover 201. A first gear 204 is provided on the bottom side of the drive block 202. A second gear 205 meshes with the side of the first gear 204. The second gear 205 is rotatably connected to the top cover 201. A stirring rod 203 is detachably connected to the bottom side of the second gear 205. A second scraper 210 is fixedly connected to the bottom side of the stirring rod 203. The second scraper 210 abuts against the inner side of the water heater 1. The drive block 202 is connected to a drive structure 3.
[0024] As a technical optimization of this utility model, the diameter of the first gear 204 is larger than the diameter of the second gear 205. The stirring rod 203 has a "T" shaped structure. A positioning block 206 meshes with the side of the second gear 205. The positioning block 206 is slidably connected to the top cover 201. A first spring 207 is fixedly connected between the positioning block 206 and the top cover 201. The positioning block 206 can provide a certain positioning effect for the stirring rod 203, reducing the free rotation of the stirring rod 203. A first spring 207 is slidably connected to each end of the stirring rod 203. A scraper 208 is provided, and a second spring 209 is fixedly connected between the first scraper 208 and the stirring rod 203. The side of the first scraper 208 abuts against the inner wall of the water heater 1. By setting the first scraper 208, combined with the second scraper 210, the bottom and side walls of the water heater 1 can be cleaned of limescale at the same time, further improving the limescale cleaning effect. At the same time, the second spring 209 connecting the first scraper 208 and the stirring rod 203 allows the first scraper 208 to fully abut against the inner wall of the water heater 1, thereby obtaining the best limescale removal effect.
[0025] As a technical optimization of this utility model, the driving structure 3 includes a rocker arm 301. The rocker arm 301 is rotatably connected to the side of the driving block 202. The rocker arm 301 has an "L" shape. To facilitate the rotation of the driving block 202, the rocker arm 301 is provided on the side of the driving block 202. A protrusion 302 is fixedly connected to the side of the rocker arm 301. A push sleeve 303 is provided on the side of the rocker arm 301. The protrusion 302 abuts against the top side of the push sleeve 303. The push sleeve 303 is slidably connected to the drive block 202. A fourth spring 307 is fixedly connected between the push sleeve 303 and the drive block 202. A connecting block 305 is slidably connected to the inner side of the push sleeve 303. A third spring 304 is fixedly connected between the end of the connecting block 305 and the push sleeve 303. A slot 306 is provided on the top side of the first gear 204. The connecting block 305 is slidably connected to the first gear 204 through the slot 306. When the user needs to clean the scale... During cleaning, first rotate the rocker arm 301 so that its end is in a vertical position, facilitating the rotation of the drive block 202. Simultaneously, the protrusion 302 on its side will abut against the top side of the push sleeve 303. At this time, the push sleeve 303 will slide downwards, causing the connecting block 305 inside the push sleeve 303 to abut against the first gear 204. Then, by rotating the rocker arm 301, the connecting block 305 will slide into the slot 306 on the side of the first gear 204 under the push of the third spring 304. At this point, the rotation of the rocker arm 301 can drive the stirring rod 203 to rotate and clean the limescale. When the water heater 1 is in normal use and limescale is not needed, the user can turn the rocker arm 301 to one side. At this time, the protrusion 302 will turn to one side and no longer contact the pushing sleeve 303. The pushing sleeve 303 will drive the connecting block 305 to slide out of the slot 306. That is, the rotation of the driving block 202 will no longer drive the stirring rod 203 to rotate, which can reduce the limescale fragments scraped off by the stirring rod 203 from mixing into the water during use.
[0026] In use, this invention features a drive block 202 on the top cover 201. When scale needs to be cleaned from the water heater 1, the inner wall of the water heater 1 is thoroughly soaked with a cleaning solution. The user then simply rotates the drive block 202. The first gear 204 on the bottom side of the drive block 202 drives the second gear 205 to rotate, which in turn rotates the stirring rod 203 on the bottom side of the second gear 205. The positioning block 206 helps to position the stirring rod 203, reducing its free rotation. The stirring rod 203 is equipped with a scraper; as the scraper rotates, it removes the scale buildup. The residual limescale on the inner wall of water heater 1 is thoroughly removed. Due to the diameter difference between the first gear 204 and the second gear 205, the stirring rod 203 can rotate at a higher speed, improving the cleaning effect on limescale. The first scraper 208, combined with the second scraper 210, can simultaneously clean limescale from the bottom and side walls of water heater 1, further enhancing the cleaning effect. Simultaneously, a second spring 209 connects the first scraper 208 and the stirring rod 203, ensuring that the first scraper 208 fully contacts the inner wall of water heater 1. Combined with the cylindrical structure of water heater 1, this allows for more effective cleaning. This method allows for more thorough cleaning of limescale without removing the top cover 201. To facilitate rotation of the drive block 202, a rocker arm 301 is provided on its side. When cleaning limescale, the user first rotates the rocker arm 301, making its end vertical. This allows for rotation of the drive block 202. Simultaneously, the protrusion 302 on its side abuts against the top of the push sleeve 303, causing the push sleeve 303 to slide downwards. This causes the connecting block 305 inside the push sleeve 303 to abut against the first gear 204. Then, the rocker arm 301 is rotated. The connecting block 305 will slide into the slot 306 on the side of the first gear 204 under the push of the third spring 304. At this time, the rotation of the rocker arm 301 can drive the stirring rod 203 to rotate and clean the scale. When the water heater 1 is in normal use without cleaning the scale, the user can turn the rocker arm 301 to one side. At this time, the protrusion 302 will turn to one side and no longer abut against the pushing sleeve 303. At this time, the pushing sleeve 303 will drive the connecting block 305 to slide out of the slot 306. That is, the rotation of the driving block 202 will no longer drive the stirring rod 203 to rotate, which can reduce the scale fragments scraped off by the stirring rod 203 from mixing into the water during use.
