The above structure is an electric steam generator 1 with automatic water addition in the prior art, which can realize automatic water addition to the electric steam generator 1. The specific structure and working content can refer to the prior art, and no further details are given here.
[0023] Furthermore, a cleaning mechanism for cleaning scale is provided inside the rectangular groove 103, and the cleaning mechanism includes an installation box 4, which is located inside the rectangular groove 103, and the left and right side ends of the installation box 4 are both provided with side openings 401. A rotating component is provided inside the installation box 4, and two groups of translation components are provided at the side ends of the rotating component. During implementation, the cleaning component can be used to clean the inner walls of the rectangular groove 103 and the rectangular groove 2 104, thereby preventing the scale from affecting the up and down movement of the slider 2 inside the rectangular groove 103 and the rectangular groove 2 104, thereby preventing the float from being inflexible in descending due to the scale, and thus preventing the automatic water addition of the electric heating steam generator 1 from being affected.
[0024] As an implementation method in this embodiment, Figure 1 , Figure 3 and Figure 4As shown, the rotating assembly includes a rotating rod 402, which is rotatably arranged between the inner bottom end and the outer top end of the installation box 4, the outer end of the rotating rod 402 is fixedly connected to a gear 403, and the top of the rotating rod 402 is fixedly connected to a rotating plate 404, and the translation assembly includes a rack 5, the bottom end of the rack 5 is slidably connected to the inner bottom end of the installation box 4 through a T-shaped slider 2, the side end of the rack 5 is fixedly connected to a collection box 501, the collection box 501 is located at the side end of the side opening 401, and the top of the collection box 501 is fixedly connected to a scraper 502, and the rack 5 is meshed with the gear 403. In practice, the installation box 4 with the collection boxes 501 on both sides that have not been unfolded is placed in a rectangular groove 103, and the installation box 4 is moved downward at this time so that the installation box 4 is located in the rectangular groove 103. The bottom end of the rectangular groove 103 is close to the water inlet groove 102. At this time, due to the limitation of the installation box 4 by the rectangular groove 103, the rotating rod 402 and the gear 403 can be rotated by rotating the rotating plate 404. At this time, the two groups of racks 5 meshing at the side ends of the gear 403 will be driven to translate by the meshing. Since the T-shaped slider 2 is slidably connected to the inner bottom of the installation box 4, the position of the rack 5 can be limited to prevent the rack 5 from moving up and down or sliding out of the installation box 4. At this time, the two groups of racks 5 can drive the two groups of collecting boxes 501 to translate and expand outward after translation, so as to facilitate the scraper 502 to contact the inner wall of the rectangular groove 103 or the rectangular groove 2 104, so as to facilitate the scraping and cleaning of the inner wall of the rectangular groove 103 or the rectangular groove 2 104.
[0025] As an implementation method in this embodiment, Figure 4 and Figure 5As shown, a mounting groove 503 is provided at the top of the collection box 501, and a limit assembly is provided inside the mounting groove 503. The limit assembly includes a spring 6, and the spring 6 is fixedly connected to the inner bottom end of the mounting groove 503. A rectangular plate 601 is fixedly connected to the top of the spring 6, and a clamp 602 is fixedly connected to the top of the rectangular plate 601. The side end of the clamp 602 is set in an arc shape. In implementation, the two sets of racks 5 can drive the two sets of collection boxes 501 to move outward and expand after translation. At this time, one set of racks 5 can move outward and expand. The clamp head 602 directly located inside the installation box 4 will pass through the side end of the side opening 401. At this time, since the side end of the clamp head 602 is arranged in an arc shape, it will be pressed by the side opening 401 into the installation groove 503 after passing through the side opening 401. At this time, the clamp head 602 and the rectangular plate 601 press the spring 6 to shrink, and at this time, the scraper 502 at the top of the collection box 501 can be driven to press against the side wall of the rectangular groove 104. When the scraper 502 contacts the inner wall of the rectangular groove 104, the clamp head 602 is pressed into the installation groove 503. When the chuck 602 is at the outer end of the installation box 4, the spring 6 will push the rectangular plate 601 to drive the clamping head 602 to move upward, so that the clamping head 602 is limited at the side end of the installation box 4. At this time, the position of the collecting box 501 is limited and fixed so that it is tightly in contact with the inner wall of the rectangular groove 104. At this time, after pulling the rotating plate 404 upward, the installation box 4 can be driven to move upward. At this time, the scraper 502 can scrape and clean the inner wall of the rectangular groove 104 upward, and the cleaned scale falls into the collecting box 501 along the scraper 502 to be collected, thereby preventing the scale from falling from the through groove in the slider 2 into the electric heating steam generator 1. Therefore, the device can facilitate the cleaning of the inner walls of the rectangular groove 1 103 and the rectangular groove 2 104, and avoid the scale affecting the up and down movement of the slider 2 in the rectangular groove 1 103 and the rectangular groove 2 104, thereby avoiding the inflexible descent of the float due to the scale, and thus avoiding affecting the automatic water addition of the electric heating steam generator 1.
[0026] As an implementation method in this embodiment, Figure 1 As shown, the top of the water tank 101 is fixedly connected with a straight plate 3, and the top of the straight plate 3 is rotatably provided with a limit frame 301. During implementation, when the scraper 502 and the installation box 4 are no longer in use, the limit frame 301 is rotated so that the limit frame 301 is located at the side end of the rotating rod 402. At this time, the limit frame 301 can lift the bottom of the rotating plate 404, so that the installation box 4 is located in the rectangular groove 1 103 and the rectangular groove 2 104, and the rectangular groove 1 103 and the rectangular groove 2 104 are blocked, thereby preventing debris from falling into the rectangular groove 103 and the rectangular groove 2 104.
[0027] Working principle: by placing the unexpanded installation box 4 of the collection boxes 501 on both sides into the rectangular groove 103, the installation box 4 is moved downward so that the installation box 4 is located at the bottom of the rectangular groove 103 near the water inlet groove 102. At this time, due to the limitation of the installation box 4 by the rectangular groove 103, the rotating rod 402 and the gear 403 can be rotated by rotating the rotating plate 404. At this time, the two sets of racks 5 meshing at the side ends of the gear 403 will be driven to translate by the meshing. Since the T-shaped slider 2 is slidably connected to the inner bottom end of the installation box 4, the position of the rack 5 can be limited to prevent the rack 5 from moving up and down or sliding out of the installation box 4. At this time, the two sets of racks After the translation, the two groups of collection boxes 501 can be translated outward and expanded. At this time, the clamping head 602 that has been located inside the installation box 4 will pass through the side end of the side opening 401. At this time, since the side end of the clamping head 602 is set in an arc shape, it will be pressed by the side opening 401 to enter the installation groove 503 after passing through the side opening 401. At this time, the clamping head 602 and the rectangular plate 601 press the spring 6 to shrink, and at this time, the scraper 502 at the top of the collection box 501 can be driven to press against the side wall of the second rectangular groove 104. When the scraper 502 contacts the inner wall of the second rectangular groove 104, the clamping head 602 is located at the outer end of the installation box 4. At this time, the spring 6 will push the rectangular plate 601 to drive the clamping head 602 to move upward, so that The clamping head 602 is limited at the side end of the installation box 4. At this time, the position of the collection box 501 is limited and fixed so that it is tightly in contact with the inner wall of the rectangular groove 104. At this time, after pulling the rotating plate 404 upward, the installation box 4 can be driven to move upward. At this time, the scraper 502 can scrape and clean the inner wall of the rectangular groove 104 upward, and the cleaned scale falls into the collection box 501 along the scraper 502 to be collected, thereby preventing the scale from falling from the through groove in the slider 2 into the electric heating steam generator 1. Then, when the inner wall of the rectangular groove 104 is cleaned, the installation box 4 is pulled out, and the clamping heads 602 at both ends are pinched downward, and the collection box 501 is pushed into the installation box 4. At this time, the direction of the installation box 4 is changed so that the installation box 4 is inserted into the rectangular groove 104. Then, after the installation box 4 moves downward, the collection box 501 is unfolded in the same way as above, so that the scraper 502 is located on the inner wall of the rectangular groove 103, and then the rotating plate 404 is pulled upward in the same way as above to clean the scale on the inner wall of the rectangular groove 103, thereby realizing the cleaning of the inner walls of the rectangular grooves 1 103 and the rectangular grooves 2 104, avoiding the influence of scale on the up and down movement of the slider 2 in the rectangular grooves 1 103 and the rectangular grooves 2 104, thereby avoiding the inflexible descent of the float due to scale, and thus avoiding affecting the automatic water addition of the electric heating steam generator 1.
