Abstract
Description
Technical Field
[0001] This invention relates to the field of descaling technology, specifically to a descaling device for electric kettles. Background Technology
[0002] After prolonged use, limescale will build up on the inner wall of an electric kettle. In areas with poor water quality, even more limescale will be produced when boiling water. Therefore, electric kettles need to be cleaned regularly to remove limescale, or the limescale inside the kettle should be removed before recycling.
[0003] Most existing scale removal devices physically break down and scrape off the scale, which can cause vibrations during the scraping process. Therefore, placing the kettle directly on the workbench for scraping can easily cause the kettle to shake and shift, thus affecting the descaling effect. Workers need to manually press the kettle to keep it in place, which poses a certain safety hazard. Therefore, a scale removal device for electric kettles is proposed to solve the above-mentioned problems. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a device for removing limescale from an electric kettle, addressing the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an electric kettle scale removal device, comprising a base, a support rod slidably connected to the inner wall of the top of the base, a clamping device provided on the inner wall of the support rod, a cleaning device provided on the top of the base, a pushing device provided on the surface of the cleaning device, and a blocking device provided on the surface of the cleaning device; the clamping device includes a bidirectional screw and a clamping plate, the bidirectional screw is rotatably connected to the inner wall of the support rod, and the clamping plate is threadedly connected to the surface of the bidirectional screw; the cleaning device includes a motor, a threaded rod, a moving disc, a collar, a pipe, a planetary gear set, a turntable, a screw, a support column, a fixed plate, a pressing valve, a slider, and an elastic brush plate, the motor is fixedly connected to the bottom wall inside the base, the threaded rod is fixedly connected to the output end of the motor, the moving disc is threadedly connected to the surface of the threaded rod, and the collar is sleeved on the... The threaded rod has a pipe fixedly connected to the surface of a collar. A planetary gear set is mounted on the surface of the threaded rod. A turntable is mounted on the top of the planetary gear set. A screw is rotatably connected to the inner wall of the turntable. A support column is fixedly connected to the inner wall of the turntable. A fixed plate is fixedly connected to the top of the support column. A pressing valve is mounted on the inner wall of the top of the fixed plate. A slider is threadedly connected to the surface of the screw. An elastic brush plate is fixedly connected to the surface of the slider. The top of the clamping plate is slidably connected to the surface of the support rod. The surface of the turntable is rotatably connected to the inner wall of the top of the base. The surface of the moving disk is in contact with the inner wall of the base. The top of the moving disk is fixedly connected to the bottom of the support rod. The surface of the pipe is fixedly connected to the inner wall of the base. Connecting rods are fixedly connected to both sides of the slider near the support column, and the surface of the connecting rod away from the slider is slidably connected to the inner wall of the support column.The planetary gear set consists of a sun gear, planet gears, and a gear disk. The top of the gear disk is fixedly connected to the bottom of the turntable, the top of the sun gear is in contact with the bottom of the turntable, and the bottom of the sun gear is fixedly connected to the top of the threaded rod. The top of the planet gears is rotatably connected to the bottom of the turntable, and the top of the planet gears is fixedly connected to the bottom of the screw. The top of the screw is rotatably connected to the bottom of the fixed plate. The fixed plate, support column, turntable, sun gear, threaded rod, collar, and pipe have interconnected through holes. When the kettle is placed upside down between the two clamping plates, rotating the crank rotates the bidirectional screw. Alternatively, a motor can be installed to rotate the bidirectional screw. The bidirectional screw pulls the two clamping plates, guided by the support rod, together and clamps the kettle, preventing shaking during subsequent scale removal and eliminating the need for manual pressing of the limit switch, thus improving the safety of the device. Afterward, the motor starts and rotates the threaded rod, which in turn rotates the internal... The moving disc, which limits the movement of the support rod, moves downwards. The moving disc drives the support rod downwards, and the support rod, through a clamping plate, moves the kettle downwards, fitting it onto multiple screws and elastic brush plates. At this point, the kettle's inner wall contacts the pressure valve on the inner wall of the fixed plate, opening it and allowing phosphoric acid descaling agent to enter the collar through a pipe. This agent then enters the inner wall of the threaded rod and is sprayed from the top of the support column. The phosphoric acid descaling agent is then sprayed from the through-hole on the pressure valve surface, softening and descaling the scale on the kettle's inner wall, facilitating subsequent scraping. The threaded rod, through a planetary gear set, drives the screw and turntable to rotate synchronously. The threaded rod, through its threads, drives the slider to rotate. However, the slider is limited by a connecting rod to the inner wall of the support column, so it can only be moved upwards or downwards by the screw. Simultaneously, the slider moves the elastic brush plates, causing them to move up and down and easily scrape off the softened and loosened scale in the kettle. The turntable also rotates, driving the elastic brush plates to rotate as well, increasing the area the elastic brush plates cover in the kettle and improving the device's descaling effect.
[0006] Preferably, the pushing device includes a movable rod, a baffle, a guide block, a mounting plate, a push plate, an elastic plate, and a movable plate. The mounting plate is fixedly connected to the surface of the support column, the movable rod is slidably connected to the inner wall of the mounting plate, the baffle is rotatably connected to the surface of the fixed plate via a torsion spring, the guide block is fixedly connected to the surface of the baffle, the push plate is fixedly connected to the bottom end of the movable rod, the elastic plate is fixedly connected to the surface of the support column, and the movable plate is installed on the side of the elastic plate away from the support column. The pushing device also includes a protective plate and a rubber... The protective plate is rotatably connected to the inner wall of the movable plate near the elastic plate via a torsion spring, and the rubber plate is fixedly connected to the surface of the protective plate; the bottom of the movable plate is in contact with the top of the turntable, the bottom of the push plate is in contact with the upper surface of the elastic plate, the top of the push plate is connected to the bottom of the mounting plate with a spring, and the top of the movable rod is in contact with the surface of the guide block. When the top wall inside the kettle contacts the press valve and sprays phosphoric acid descaling agent, the inner wall of the kettle also contacts the baffle and pushes it to rotate, causing the baffle to rotate and allowing the spray... The sprayed phosphoric acid descaling agent splashes onto its own surface, increasing the spray range and improving the descaling effect in the kettle. Simultaneously, the scale scraped off by the upward-moving elastic brush falls onto the protective plate, which guides the scale onto the side of the moving plate away from the elastic plate. During descaling, the kettle moves up and down on the screw surface. During this time, the baffle is intermittently pushed and rotated by the kettle. The rotation of the baffle causes the guide block to rotate and move upward, freeing the moving rod from the guide block's limitation. Therefore, the spring causes the moving rod and the push plate to move up and down. When the push plate is no longer limiting the elastic plate, the elastic plate returns to its original position and arches under its own elastic force. The elastic plate drives the moving plate to move towards the support column. When the kettle moves up and no longer contacts the baffle, the torsion spring will drive the baffle to return to its original position. At this time, the baffle pushes the moving rod down through the guide block and its arc surface. The moving rod drives the push plate down, and the push plate pushes the elastic plate to deform. The elastic plate pushes the moving plate to move away from the support column. The moving plate pushes the scale to move to the outside of the turntable, preventing the scraped scale from accumulating on the turntable and affecting subsequent scale cleaning.
[0007] Preferably, the blocking device includes a telescopic column, a guide plate, a connecting plate, a telescopic rod, a sliding rod, a magnet, a stop bar, and a magnetic plate. The telescopic column is fixedly connected to the surface of the elastic brush plate, the connecting plate is fixedly connected to the surface of the slider, the guide plate is fixedly connected to the surface of the telescopic end of the telescopic column, the telescopic rod is fixedly connected to the side of the connecting plate near the elastic brush plate, the sliding rod is slidably connected to the inner wall of the connecting plate by a spring, the magnet is fixedly connected to the end of the sliding rod near the support column, the stop bar is fixedly connected to the surface of the end of the sliding rod away from the magnet, and the magnetic plate is fixedly connected to the circumferential surface of the moving rod. The magnet and the magnetic plate are magnetically attracted to each other. The end of the telescopic column away from the elastic brush plate is fixedly connected to the surface of the connecting plate, and the end of the telescopic rod away from the connecting plate is fixedly connected to the surface of the guide plate. When the elastic brush plate comes into contact with scale, it will be deformed by the scale, causing the elastic brush plate to reciprocate during the scale removal process. The deformation of the elastic brush plate pushes the telescopic column to extend and retract, and the telescopic column drives the guide plate to move towards the connecting plate. As the brush plate moves upward, the scale scraped off falls between the flexible brush plate and the connecting plate. The moving guide plate guides the scale, ensuring it falls regularly onto the protective plate and slides down to the side of the moving plate away from the support column. This facilitates the scale being pushed out by the moving plate. When the flexible brush plate moves upward, the scale scraped off falls between the connecting plate and the flexible brush plate, but the falling scale is blocked by the telescopic rod, sliding rod, and stop bar to prevent the flexible brush plate from moving too high and causing scale to fall. The fallen scale, due to its uneven surface, easily falls towards the support column. The upward displacement of the support column affects the subsequent scale discharge effect. Only when the elastic brush plate moves down again and the connecting plate moves the magnet to the magnetic plate will the magnetic plate attract the magnet. The magnet will move the slide rod to the moving rod, and the slide rod will move the stop rod. The distance between the stop rod and the guide plate will increase, allowing the scale that is limited to fall down and contact the protective plate. The protective plate will buffer and guide it, ensuring that the scale falling at this height can be guided by the protective plate and fall on the side of the moving plate away from the support column, which is convenient for subsequent scale discharge and cleaning.
[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:
[0009] 1. This electric kettle scale removal device, through the coordinated operation of a base, support rod, bidirectional screw, clamping plate, motor, threaded rod, moving disc, collar, pipe, planetary gear set, turntable, screw, support column, fixing plate, press valve, slider, and elastic brush plate, can spray phosphoric acid descaling agent from the through hole on the surface of the press valve to soften and remove scale on the inner wall of the kettle, making it easier to scrape off the scale. It also reduces the shaking of the kettle during scale removal, improves the stability of the kettle and the scraping effect of the internal scale, thereby improving the scale removal effect in the kettle.
[0010] 2. This electric kettle scale removal device works in coordination with a moving rod, baffle, guide block, mounting plate, push plate, elastic plate, moving plate, protective plate, and rubber plate. When the top wall inside the kettle contacts the press valve and is sprayed with phosphoric acid descaling agent, the inner wall of the kettle also contacts the baffle and pushes it to rotate. The rotation of the baffle causes the sprayed phosphoric acid descaling agent to spray onto its own surface and splash, thereby increasing the spray range of the phosphoric acid descaling agent and improving the scale removal effect in the kettle. At the same time, the moving plate pushes the scale to the outside of the turntable to prevent the scraped scale from accumulating on the turntable and affecting subsequent scale cleaning.
[0011] 3. This electric kettle limescale removal device works in concert with a telescopic column, guide plate, connecting plate, telescopic rod, sliding rod, magnet, stop bar, and magnetic plate. When the elastic brush plate comes into contact with limescale, it is deformed by the limescale, causing the elastic brush plate to reciprocate during the limescale removal process. The deformation of the elastic brush plate pushes the telescopic column to extend and retract, and the telescopic column drives the guide plate to move towards the connecting plate. As the elastic brush plate moves upward, the scraped limescale falls between the elastic brush plate and the connecting plate. The moving guide plate guides the limescale, ensuring that it falls regularly onto the protective plate and slides to the side of the moving plate away from the support column, facilitating the removal of the limescale by the moving plate. The limescale scraped as the elastic brush plate moves upward falls between the connecting plate and the elastic brush plate. The scale falls between the plates, but the falling scale is blocked by the telescopic rod, sliding rod, and stop rod to prevent the elastic brush plate from rising too high and causing the scale to fall. Because of its uneven surface, the fallen scale is easy to bounce and move towards the support column, which will affect the subsequent scale discharge effect. Only when the elastic brush plate moves down again and the connecting plate moves the magnet to the magnetic plate, the magnetic plate attracts the magnet. The magnet moves the sliding rod to the moving rod, and the sliding rod moves the stop rod. The distance between the stop rod and the guide plate increases, so that the scale that is limited can fall and contact the protective plate. The protective plate will buffer and guide it, ensuring that the scale falling at this height can be guided by the protective plate and fall on the side of the moving plate away from the support column, which is convenient for subsequent scale discharge and cleaning.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see Figures 1-9One embodiment of the present invention is as follows: an electric kettle scale removal device includes a base 1, a support rod 2 slidably connected to the inner wall of the top of the base 1, a clamping device 3 provided on the inner wall of the support rod 2, a cleaning device 4 provided on the top of the base 1, a pushing device 5 provided on the surface of the cleaning device 4, and a blocking device 6 provided on the surface of the cleaning device 4; the clamping device 3 includes a bidirectional screw 31 and a clamping plate 32, the bidirectional screw 31 is rotatably connected to the inner wall of the support rod 2, and the clamping plate 32 is threadedly connected to the surface of the bidirectional screw 31; the cleaning device 4 includes a motor 41, a threaded rod 42, a moving disc 43, a collar 44, a pipe 45, and a planetary gear set 4. 6. Turntable 47, screw 48, support column 49, fixing plate 410, pressing valve 411, slider 412, and elastic brush plate 413. Place the kettle upside down between the two clamping plates 32. Rotate the crank to drive the bidirectional screw 31 to rotate. Alternatively, a motor can be installed to drive the bidirectional screw 31 to rotate. The bidirectional screw 31 then causes the two clamping plates 32, guided by the support rod 2, to converge and clamp the kettle, preventing shaking during subsequent scale removal. This also eliminates the need for manual pressing of the limit switch, improving the device's safety. The motor 41 is fixedly connected to the bottom wall inside the base 1, and the threaded rod 42 is fixedly connected to the output end of the motor 41. A movable disk 43 is threadedly connected to the surface of a threaded rod 42. A collar 44 is fitted onto the surface of the threaded rod 42. A pipe 45 is fixedly connected to the surface of the collar 44. A planetary gear set 46 is mounted on the surface of the threaded rod 42. A turntable 47 is mounted on the top of the planetary gear set 46. A screw 48 is rotatably connected to the inner wall of the turntable 47. A support column 49 is fixedly connected to the inner wall of the turntable 47. A fixed plate 410 is fixedly connected to the top of the support column 49. A press valve 411 is installed on the inner wall of the top of the fixed plate 410. A slider 412 is threadedly connected to the surface of the screw 48. An elastic brush plate 413 is fixedly connected to the surface of the slider 412. A motor 41 starts and drives the screw... The threaded rod 42 rotates, and the threaded rod 42 drives the moving disk 43, which is limited by the inner support rod 2, to move down. The moving disk 43 drives the support rod 2 to move down. The support rod 2 drives the kettle to move down through the clamp 32 and fits onto multiple screws 48 and elastic brush plate 413. At this time, after the kettle moves down, the inner wall will contact the press valve 411 on the inner wall of the fixed plate 410 and push the press valve 411 to open, so that the phosphoric acid descaling agent enters the collar 44 through the pipe 45, and then enters the inner wall of the threaded rod 42 and is sprayed out from the top of the support column 49, so that the phosphoric acid descaling agent is sprayed out from the through hole on the surface of the press valve 411 and descaling and softening the scale on the inner wall of the kettle, making it easier to scrape off the scale later.The top of clamping plate 32 is slidably connected to the surface of support rod 2; the surface of turntable 47 is rotatably connected to the inner wall of the top of base 1; the surface of movable disk 43 is in contact with the inner wall of base 1; the top of movable disk 43 is fixedly connected to the bottom of support rod 2; the surface of pipe 45 is fixedly connected to the inner wall of base 1; connecting rods are fixedly connected to both sides of slider 412 near support column 49, and the surface of the connecting rod away from slider 412 is slidably connected to the inner wall of support column 49; planetary gear set 46 consists of sun gear, planet gears and gear disk; the top of gear disk is fixedly connected to the bottom of turntable 47; the top of sun gear is in contact with the bottom of turntable 47; the bottom of sun gear is fixedly connected to the top of threaded rod 42; the top of planet gear is rotatably connected to the bottom of turntable 47; the top of planet gear is fixedly connected to the bottom of screw 48; the screw... The top of screw 48 is rotatably connected to the bottom of fixed plate 410. Fixed plate 410, support column 49, turntable 47, sun gear, threaded rod 42, collar 44, and pipe 45 have interconnected through holes. Threaded rod 42 drives screw 48 and turntable 47 to rotate synchronously via planetary gear set 46, causing screw 42 to drive slider 412 to rotate via its threads. However, slider 412 is limited by a connecting rod to the inner wall of support column 49, so slider 412 can only be moved up or down by screw 48. Simultaneously, slider 412 drives elastic brush plate 413 to move, causing elastic brush plate 413 to move up and down and easily scrape off softened and loose scale in the kettle. At the same time, turntable 47 also rotates, driving elastic brush plate 413 to rotate, which increases the area of elastic brush plate 413 that cleans scale in the kettle, improving the descaling effect of the device.
[0024] Working principle: The kettle is placed upside down between two clamping plates 32. Rotating the crank drives the bidirectional screw 31 to rotate. Alternatively, a motor can be installed to drive the bidirectional screw 31. The bidirectional screw 31 causes the two clamping plates 32, guided by the support rod 2, to converge and clamp the kettle, preventing it from shaking during subsequent scale removal. This eliminates the need for manual pressing of the limit switch, improving the device's safety. Then, the motor 41 starts and drives the threaded rod 42 to rotate. The threaded rod 42, through its threads, drives the movable disc 43, which is limited by the inner support rod 2, to move downwards. The movable disc 43 then drives the support rod 2 downwards. The support rod 2, through the clamping plates 32, causes the kettle to move downwards and fit onto multiple screws 48 and the elastic brush plate 413. After the kettle moves downwards, its inner wall contacts the pressing valve 411 on the inner wall of the fixed plate 410, opening the valve and allowing the phosphoric acid descaling agent to flow through the pipe. The phosphoric acid descaling agent enters the collar 44 through channel 45, then enters the inner wall of the threaded rod 42 and is sprayed out from the top of the support column 49. This causes the phosphoric acid descaling agent to be sprayed out from the through hole on the surface of the pressure valve 411 and softens the scale on the inner wall of the kettle, making it easier to scrape off the scale later. The threaded rod 42 drives the screw 48 and the turntable 47 to rotate synchronously through the planetary gear set 46. This causes the threaded rod 42 to drive the slider 412 to rotate through the thread. However, the slider 412 is limited to the inner wall of the support column 49 by the connecting rod. Therefore, the slider 412 can only be moved up or down by the screw 48. At the same time, the slider 412 drives the elastic brush plate 413 to move. The elastic brush plate 413 moves up and down and easily scrapes off the softened and loose scale in the kettle. At the same time, the turntable 47 also rotates and drives the elastic brush plate 413 to rotate, which can increase the area of the elastic brush plate 413 cleaning scale in the kettle and improve the descaling effect of the device.
[0025] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the pushing device 5 includes a moving rod 51, a baffle 52, a guide block 53, a mounting plate 54, a push plate 55, an elastic plate 56, and a moving plate 57. The mounting plate 54 is fixedly connected to the surface of the support column 49, the moving rod 51 is slidably connected to the inner wall of the mounting plate 54, the baffle 52 is rotatably connected to the surface of the fixed plate 410 via a torsion spring, the guide block 53 is fixedly connected to the surface of the baffle 52, the push plate 55 is fixedly connected to the bottom end of the moving rod 51, the elastic plate 56 is fixedly connected to the surface of the support column 49, and the moving plate 57 is installed on the side of the elastic plate 56 away from the support column 49. When water... When the top wall inside the kettle contacts the press valve 411 and the phosphoric acid descaling agent is sprayed, the inner wall of the kettle also contacts the baffle 52 and pushes it to rotate. The rotation of the baffle 52 causes the sprayed phosphoric acid descaling agent to spray onto its own surface and splash, thereby increasing the spray range of the phosphoric acid descaling agent and improving the descaling effect of the scale in the kettle. The pushing device 5 also includes a protective plate 58 and a rubber plate 59. The protective plate 58 is rotatably connected to the inner wall of the moving plate 57 near the elastic plate 56 by a torsion spring. The rubber plate 59 is fixedly connected to the surface of the protective plate 58. The scale scraped by the elastic brush plate 413 will fall onto the protective plate 58, and the protective plate 58 will guide the scale. This causes the kettle to fall onto the side of the movable plate 57 away from the elastic plate 56. During descaling, the kettle moves back and forth on the surface of the screw 48. At this time, the baffle 52 is intermittently pushed and rotated by the kettle. After the baffle 52 rotates, it drives the guide block 53 to rotate and move upwards, so that the movable rod 51 is no longer limited by the guide block 53. Therefore, the spring will drive the movable rod 51 and the push plate 55 to move upwards and reset. The push plate 55 no longer limits the elastic plate 56. At this time, the elastic plate 56 resets and arches under its own elastic force. The elastic plate 56 drives the movable plate 57 to move towards the support column 49. When the kettle moves upwards and no longer contacts the baffle 52, the torsion spring will drive the baffle 52 to reset. At this time, the baffle 52... The guide block 53 and its arc-shaped surface push the moving rod 51 downward, the moving rod 51 drives the push plate 55 downward, the push plate 55 pushes the elastic plate 56 to deform, the elastic plate 56 pushes the moving plate 57 to move away from the support column 49, the moving plate 57 pushes the scale to move to the outside of the turntable 47 to prevent the scraped scale from accumulating on the turntable 47 and affecting the subsequent scale cleaning; the bottom of the moving plate 57 is in contact with the top of the turntable 47, the bottom of the push plate 55 is in contact with the upper surface of the elastic plate 56, the top of the push plate 55 and the bottom of the mounting plate 54 are provided with springs, and the top of the moving rod 51 is in contact with the surface of the guide block 53.
[0026] The blocking device 6 includes a telescopic column 61, a guide plate 62, a connecting plate 63, a telescopic rod 64, a sliding rod 65, a magnet 66, a stop bar 67, and a magnetic plate 68. The telescopic column 61 is fixedly connected to the surface of the elastic brush plate 413, the connecting plate 63 is fixedly connected to the surface of the slider 412, the guide plate 62 is fixedly connected to the surface of the telescopic end of the telescopic column 61, the telescopic rod 64 is fixedly connected to the side of the connecting plate 63 near the elastic brush plate 413, the sliding rod 65 is slidably connected to the inner wall of the connecting plate 63 by a spring, the magnet 66 is fixedly connected to the end of the sliding rod 65 near the support column 49, and the stop bar 67 is fixedly connected to the end of the sliding rod 65 far from the support column 49. On the surface of the end away from magnet 66, magnetic plate 68 is fixedly connected to the circumferential surface of moving rod 51. When elastic brush plate 413 comes into contact with scale, it will be deformed by the scale, causing elastic brush plate 413 to reciprocate during the scale removal process. The deformation of elastic brush plate 413 pushes telescopic column 61 to extend and retract. Telescopic column 61 drives guide plate 62 to move towards connecting plate 63. When elastic brush plate 413 moves upward, the scale scraped off will fall between elastic brush plate 413 and connecting plate 63. The moving guide plate 62 will guide the scale, ensuring that the scale can fall regularly on protective plate 58 and slide down to moving plate 57 away from support column. On one side of 49, scale is easily pushed out by the moving plate 57; magnet 66 and magnetic plate 68 are magnetically attracted to each other; the end of telescopic column 61 away from elastic brush plate 413 is fixedly connected to the surface of connecting plate 63; the end of telescopic rod 64 away from connecting plate 63 is fixedly connected to the surface of guide plate 62. When elastic brush plate 413 moves upward, the scale scraped off falls between connecting plate 63 and elastic brush plate 413, but the falling scale is blocked by telescopic rod 64, sliding rod 65 and stop rod 67 to prevent elastic brush plate 413 from moving too high and causing scale to fall. The fallen scale is easily pushed towards support column 49 because of the uneven surface. The upward displacement affects the subsequent scale discharge effect. Only when the elastic brush plate 413 moves down again and the connecting plate 63 moves the magnet 66 to the magnetic plate 68 will the magnetic plate 68 attract the magnet 66. The magnet 66 will drive the slide rod 65 to move to the moving rod 51. The slide rod 65 will drive the stop rod 67 to move. The distance between the stop rod 67 and the guide plate 62 will increase, so that the scale that is limited can fall and contact the protective plate 58. The protective plate 58 will buffer and guide it, ensuring that the scale falling at this height can be guided by the protective plate 58 and fall on the side of the moving plate 57 away from the support column 49, which is convenient for subsequent scale discharge and cleaning.
[0027] Working principle: When the top wall inside the kettle contacts the press valve 411 and the phosphoric acid descaling agent is sprayed, the inner wall of the kettle also contacts the baffle 52 and pushes it to rotate. The rotation of the baffle 52 causes the sprayed phosphoric acid descaling agent to spray onto its own surface and splash, thereby increasing the spray range of the phosphoric acid descaling agent and improving the descaling effect in the kettle. At the same time, the scale scraped by the elastic brush 413 will fall onto the protective plate 58. The protective plate 58 will guide the scale to fall onto the side of the moving plate 57 away from the elastic plate 56. During the descaling process, the kettle will move up and down on the surface of the screw 48. At this time, the baffle 52 will be intermittently pushed and rotated by the kettle. After the baffle 52 rotates, it will drive the guide block 53 to rotate and move upward, so that the moving rod 51 is no longer guided by the guide block. With the spring at limit 53, the moving rod 51 and push plate 55 will move upward and reset. The push plate 55 will no longer limit the elastic plate 56. At this time, the elastic plate 56 will reset and arch under its own elastic force. The elastic plate 56 will drive the moving plate 57 to move towards the support column 49. When the kettle moves upward and no longer contacts the baffle 52, the torsion spring will drive the baffle 52 to reset. At this time, the baffle 52 will push the moving rod 51 downward through the guide block 53 and its arc-shaped surface. The moving rod 51 will drive the push plate 55 downward. The push plate 55 will push the elastic plate 56 to deform. The elastic plate 56 will push the moving plate 57 to move away from the support column 49. The moving plate 57 will push the scale to move to the outside of the turntable 47 to prevent the scraped scale from accumulating on the turntable 47 and affecting the subsequent scale cleaning.
[0028] When the flexible brush plate 413 comes into contact with limescale, it deforms due to the resistance of the limescale, causing the flexible brush plate 413 to reciprocate during the limescale removal process. The deformation of the flexible brush plate 413 pushes the telescopic column 61 to extend and retract. The telescopic column 61 drives the guide plate 62 to move towards the connecting plate 63. When the flexible brush plate 413 moves upward, the limescale scraped off will fall between the flexible brush plate 413 and the connecting plate 63. The moving guide plate 62 will guide the limescale, ensuring that the limescale can fall regularly onto the protective plate 58 and slide down to the side of the moving plate 57 away from the support column 49, so that the limescale can be pushed out by the moving plate 57. When the flexible brush plate 413 moves upward, the limescale scraped off will fall between the connecting plate 63 and the flexible brush plate 413, but the falling limescale is blocked by the telescopic rod 64, the sliding rod 65 and the stop. On rod 67, to prevent the elastic brush plate 413 from moving too high and causing scale to fall, the fallen scale is easily displaced towards the support column 49 due to its uneven surface, thus affecting the subsequent scale discharge effect. Only when the elastic brush plate 413 moves down again and the connecting plate 63 drives the magnet 66 to the magnetic plate 68, the magnetic plate 68 attracts the magnet 66. The magnet 66 drives the slide rod 65 to move towards the moving rod 51. The slide rod 65 drives the stop rod 67 to move. The distance between the stop rod 67 and the guide plate 62 increases, allowing the limited scale to fall and contact the protective plate 58. The protective plate 58 will buffer and guide it, ensuring that the scale falling at this height can be guided by the protective plate 58 and fall on the side of the moving plate 57 away from the support column 49, which facilitates the subsequent scale discharge and cleaning.
