[0018] The utility model is described in detail below in combination with the drawings and specific embodiments, but not as the limitation of the utility model.

[0019] As Figures 1-4As shown, a water heater device with scale removal function, including inner shell shell 1, the upper and lower sides of the inner shell shell 1 are respectively provided with water inlet 101 and drain 102, respectively for water input and output, the outer middle part of the inner shell shell 1 is provided with a two-way electric push rod 2, the two telescopic rods of the two-way electric push rod 2 are respectively fixedly connected with the mounting plate 3, the two mounting plates 3 are respectively provided with a motor 4, the two ends of the inner shell shell 1 are symmetrically connected with two round rods 5, one end of the round rod 5 is drivingly connected with the output shaft of the motor 4 on the same side, the other end of the round rod 5 is fixedly connected with the annular scraper 6, the scraper 6 is used for scraping the inner side wall of the inner shell shell 1, the side of the two scrapers 6 close to each other is slidably provided with a scraper 7, the scraper 7 on each scraper 6 is used for scraping the other scraper 6, the length of the scraper 7 is equivalent to the difference between the outer radius and the inner radius of the scraper 6, the scraper 7 is a triangular prism, when the two ends of the two round rods 5 close to each other abut, the distance between the two mounting plates 3 is slightly smaller than the column width of the scraper 7.

[0020] The scraper 6 is provided with a sliding groove 601, the scraper 7 is slidably connected in the sliding groove 601, the scraper 7 and the inner bottom of the sliding groove 601 are connected with three elastic members 8, the elastic members 8 ensure that the scraper 7 can be automatically reset during scraping.

[0021] The outer left and right ends of the inner shell shell 1 are fixedly connected with guide rods 9, the mounting plates 3 are slidably connected with the guide rods 9, ensuring that the mounting plates 3 can stably reciprocate under the drive of the two-way electric push rod.

[0022] The end of the guide rod 9 away from the inner shell shell 1 is fixedly connected with a limiting block 10, which is used to limit the movement range of the mounting plate 3 and prevent it from being separated from the guide rod 9.

[0023] Working principle: initially, the telescopic rods of the two-way electric push rod 2 are in the elongated state, so that the distance between the two mounting plates 3 is kept maximum, at this time, the sides of the two scrapers 6 away from each other are respectively closely attached to the left and right sides of the inner shell shell 1, keeping the left and right sides of the inner shell shell 1 not in contact with the water body, during use, water is input through the water inlet 101 of the inner shell shell 1 and output through the drain 102 of the inner shell shell 1.

[0024] When the inner tank shell 1 is used for a long time to produce scale, the scale inside the inner tank shell 1 needs to be removed, first, the water in the inner tank shell 1 is discharged through the drain port 102, then the extension rod of the bidirectional electric push rod 2 is retracted, so that the two mounting plates 3 are close to each other, until the ends of the two round rods 5 close to each other abut, in this process, the round rod 5 drives the scraper 6 connected thereto to scrape the inner wall of the inner tank shell 1 once, then the extension rod of the bidirectional electric push rod 2 is retracted multiple times, so that the two scrapers 6 can reciprocally scrape the inner wall of the inner tank shell 1 to remove scale, then when the ends of the two round rods 5 close to each other abut, the right motor 4 drives the round rod 5 and the scraper 6 connected thereto to rotate, so that the scraping strip 7 on the scraper 6 corresponding to the right round rod 5 scrapes the left scraper 6, specifically, when the right scraping strip 7 rotates with the scraper 6 and abuts against the left scraping strip 7, since the two scraping strips 7 are both triangular prisms, the two scraping strips 7 will be squeezed during relative rotation and contact, and the two scraping strips 7 are respectively squeezed into the corresponding sliding groove 601, and the corresponding elastic member 8 is compressed, so as not to hinder the rotation of the right scraper 6, so that the right scraping strip 7 can smoothly complete the scraping of the left scraper 6 to remove the scale on the left scraper 6, after the right scraping strip 7 rotates away from the left scraping strip 7, the left scraping strip 7 is automatically reset under the elastic action of the corresponding elastic member 8, and the left scraper 6 is cleaned, then the left motor 4 drives the round rod 5 connected thereto to rotate, so that the left scraping strip 7 scrapes the right scraper 6 to remove the scale on the right scraper 6, in addition, during the scraping process of the scraping strip 7 on the scraper 6, the end portion of the scraping strip 7 can also scrape the part of the inner wall of the inner tank shell 1 between the two mounting plates 3, so that the inner wall of the inner tank shell 1 can be scraped.

[0025] Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
