The sliding blocks 5 are connected to the inner wall of the water tank 34 and the inner wall of the water tank 34 is provided with a plurality of sliding blocks 5. 6 rotates to drive the internal threaded ring 33 to start moving. Driven by the internal threaded ring 33, the first connecting ring 4 moves upward along the support tube 34. The first connecting ring 4 drives the second connecting ring 29 to move synchronously. The threaded rod 6 is movably connected to the support tube 34. The second connecting ring 29 is sleeved on the outside of the first connecting ring 4. The second connecting ring 29 is provided with a plurality of groups of teeth 31 on the side close to the first connecting ring 4. A transmission gear 32 is movably connected to the first connecting ring 4.

[0028] The transmission gear 32 is meshed with the teeth 31. When the micro motor is started, the transmission gear 32 is driven to rotate. Since the transmission gear 32 is meshed with the plurality of groups of teeth 31, the second connecting ring 29 is driven by the transmission gear 32 to rotate. The second connecting ring 29 is fixedly connected to a plurality of groups of connecting blocks 3 on the side away from the first connecting ring 4. A connecting groove 26 is provided in the end of the connecting block 3 away from the second connecting ring 29. A support block 28 is movably connected in the connecting groove 26. When the second connecting ring 29 rotates counterclockwise, the connecting groove 26 will not limit the support block 28, and the support block 28 will move to one side. When the second connecting ring 29 moves clockwise, the connecting groove 26 will limit the support block 28, and the support block 28 will not rotate along the connecting groove 26.

[0029] A limiting cavity 23 is provided in one end of the support block 28 away from the connecting block 3, and a T-shaped rod 24 is slidably connected in the limiting cavity 23.

A first spring 25 is fixedly connected in the limiting cavity 23, and the other end of the first spring 25 is fixedly connected to the T-shaped rod 24. Under the elastic force of the first spring 25, the arc plate 2 will always be in contact with the inner wall of the water tank body 1, and the connecting block 3 is provided with a receiving groove 20, and the receiving groove 20 is slidably connected to the blocking plate 22. When the blocking plate 22 is completely received in the receiving groove 20, the cleaning liquid in the liquid storage chamber 30 is discharged from the liquid guide groove 27 and falls onto the surface of the scale. Several groups of arc-shaped plates 2 rotate and move downward so that the cleaning liquid is evenly sprayed on the surface of the scale. A second spring 19 is fixedly connected in the receiving groove 20, and the other end of the second spring 19 is fixedly connected to the blocking plate 22. The blocking plate 22 is away from the second spring 19 and is clamped into the liquid guide groove 27.

[0030] When the second connecting ring 29 stops rotating, the blocking plate 22 pops out from the receiving groove 20 under the elastic force of the second spring 19 and blocks the liquid guide groove 27 again. The liquid guide groove 27 is arranged in the connecting block 3. The liquid guide groove 27 is connected to the liquid storage chamber 30. The liquid storage chamber 30 is arranged in the second connecting ring 29. The blocking plate 22 is fixedly connected to a lever 21 on the side close to the support block 28. The lever 21 extends into the connecting groove 26 away from the end of the blocking plate 22. The movement of the arc plate 2 drives the support block 28 to move. The rotation of the support block 28 drives the lever 21 to start moving. The movement of the lever 21 drives the blocking plate 22 to move into the receiving groove 20. The lower end of the second connecting ring 29 is fixedly connected to several groups of particle boards 10. The particle board 10 can break up the scale in the annular groove 9 when rotating.

[0031] Example 2:

[0032] On the basis of Example 1, in order to enable the first connecting ring 4 to move up and down along the support tube 34, one end of the threaded rod 6 extends out of the water tank body 1 and is fixedly connected to the output end of the motor 17. The motor 17 is fixedly installed in the protective box 16. The protective box 16 is fixedly connected to the upper end of the water tank body 1. The protective box 16 can protect the motor 17. The upper end of the water tank body 1 is fixedly connected to the water inlet pipe 18. The external water source can be introduced into the water tank body 1 through the water inlet pipe 18. The upper end of the second connecting ring 29 is fixedly connected to the connecting pipe 37. The connecting pipe 37 is connected to the liquid storage chamber 30. When the connecting pipe 37 enters the through groove 15, due to the connecting pipe The upper end of 37 is inclined, and the lower end of T-shaped plate 12 is also inclined. At this time, under the pressure of connecting tube 37, T-shaped plate 12 begins to move inward. A through groove 15 is provided in the upper end of water tank body 1. The position of through groove 15 corresponds to connecting tube 37. T-shaped plate 12 is provided in through groove 15. T-shaped plate 12 is slidably connected to guide cavity 14. Guide cavity 14 is provided in water tank body 1. A return spring 13 is fixedly connected to the guide cavity 14. The other end of return spring 13 is fixedly connected to T-shaped plate 12. When connecting tube 37 re-enters water tank body 1, under the elastic force of return spring 13, T-shaped plate 12 blocks through groove 15 again.

[0033] The lower side of the second connecting ring 29 is provided with an annular groove 9, which can collect the scraped scale. The annular groove 9 is opened in the water tank body 1, and a filter plate 8 is fixedly connected to the water tank body 1. The filter plate 8 can isolate larger scale. A first drain pipe 11 is fixedly connected to the lower end of the water tank body 1. The first drain pipe 11 is connected to the annular groove 9. The broken scale passes through the filter plate 8 under the flushing of the water source and enters the first drain pipe 11. The water source with scale passes through the three-way solenoid valve 36 from the second drain pipe 39. The first drain pipe 11 is fixedly connected to the input end of the three-way solenoid valve 36. Both sets of output ends of the three-way solenoid valve 36 are fixedly connected to the second drain pipe 39. In actual use, one set of second drain pipes 39 can be used as a hot water outlet pipe, and one set of second drain pipes 39 can be used as a wastewater drain pipe. A slip ring 38 is fixedly sleeved on the outside of the first connecting ring 4. The slip ring 38 is slidably connected to the guide groove 35, and the guide groove 35 is opened in the second connecting ring 29.

[0034] In addition, in order to achieve the above object, the present invention also provides a method for the above-mentioned descaling device of the air energy water tank, comprising the following steps:

[0035] S1. Turn on the motor 17 to move the first connecting ring 4 upward along the support tube 34. When the connecting tube 37 is fully inserted into the water tank body 1, add the prepared cleaning liquid into the liquid storage chamber 30 through the connecting tube 37. After the addition is completed, the connecting tube 37 is allowed to enter the water tank body 1. The transmission gear 32 is controlled to drive the second connecting ring 29 to rotate counterclockwise. The curved plate 2 will be driven to rotate to one side. The support block 28 rotates and drives the lever 21 to start moving, so that the blocking plate 22 is stored in the storage groove 20.

[0036] S2. The cleaning liquid in the liquid storage chamber 30 falls from the liquid guide groove 27 onto the surface of the scale to soften the scale. The first connecting ring 4 is controlled to move to the upper end and the second connecting ring 29 is controlled to rotate clockwise. The first connecting ring 4 is controlled to move downward. Under the rotation of the plurality of groups of curved plates 2, the scale falls off the inner wall of the water tank body 1. The plurality of groups of curved plates 2 rotate downward to evenly scrape off the scale on the surface of the water tank body 1. The external water source brings the scraped scale into the annular groove 9. Driven by the second connecting ring 29, the plurality of groups of particle boards 10 break up the scale.

[0037] S3. Open the three-way solenoid valve 36 to connect the first drain pipe 11 with a group of second drain pipes 39. The broken scale passes through the filter plate 8 under the flushing of the water source and enters the first drain pipe 11. The water source with scale passes through the three-way solenoid valve 36 and flows out of the second drain pipe 39. When all the scale is broken by the particle board 10, stop the rotation of the second connecting ring 29 and drive it back to the upper end of the water tank body 1.

[0038] Working principle: when in use, when it is necessary to clean the scale in the water tank body 1, the motor 17 is turned on to drive the threaded rod 6 to start rotating, and the rotation of the threaded rod 6 drives the internal threaded ring 33 to start moving. Driven by the internal threaded ring 33, the first connecting ring 4 moves upward along the support tube 34, and the first connecting ring 4 drives the second connecting ring 29 to move synchronously. When the connecting tube 37 enters the through groove 15, since the upper end of the connecting tube 37 is inclined, and the lower end of the T-plate 12 is also inclined, at this time, the connecting tube 37 is in a state of rotation. Under the pressure of the return spring 13, the T-shaped plate 12 begins to move inward. At this time, the return spring 13 is compressed. When the connecting tube 37 is fully extended, the prepared cleaning liquid can be added to the liquid storage chamber 30 through the connecting tube 37. When the addition is completed, the motor 17 is controlled to rotate in the opposite direction. At this time, the first connecting ring 4 begins to move downward, and the connecting tube 37 re-enters the water tank body 1. At the same time, under the elastic force of the return spring 13, the T-shaped plate 12 blocks the through slot 15 again, and the micro motor connected to the output end of the transmission gear 32 starts to rotate;

[0039] The transmission gear 32 drives the second connecting ring 29 to rotate counterclockwise. At the same time, the first connecting ring 4 is controlled to move downward during the rotation of the second connecting ring 29. Under the elastic force of the first spring 25, the arc plate 2 will always be in contact with the inner wall of the water tank body 1. Since the second connecting ring 29 rotates counterclockwise, the arc plate 2 will be driven to one side to start rotating. The movement of the arc plate 2 drives the support block 28 to start moving. The rotation of the support block 28 drives the lever 21 to start moving. The movement of the lever 21 drives the blocking plate 22 to move into the receiving groove 20. At this time, the second connecting ring 29 rotates counterclockwise. The spring 19 is compressed, and when the blocking plate 22 is completely retracted into the receiving groove 20, the cleaning liquid in the liquid storage chamber 30 is discharged from the liquid guide groove 27 and falls onto the surface of the scale. The groups of curved plates 2 rotate and move downward so that the cleaning liquid is evenly sprayed on the surface of the scale. When the cleaning liquid softens the scale, the first connecting ring 4 is controlled to move to the upper end, and the transmission gear 32 is controlled to rotate in the opposite direction to drive the second connecting ring 29 to rotate clockwise. Under the elastic force of the second spring 19, the blocking plate 22 pops out of the receiving groove 20 and re-blocks the liquid guide groove 27.

[0040] At the same time, the curved plate 2 returns to its original position, and the second connecting ring 29 rotates clockwise to control the first connecting ring 4 to move downward. The curved plate 2 will not move under the limiting effect of the connecting groove 26. At this time, under the rotation of several groups of curved plates 2, scale falls off from the inner wall of the water tank body 1, and several groups of curved plates 2 rotate downward to evenly scrape off the scale on the surface of the water tank body 1. At this time, the external water pipe is connected to the water inlet pipe 18, and the external water source enters the water tank body 1 along the water inlet pipe 18 and brings the scraped scale into the annular groove 9. At the same time, the rotation of the second connecting ring 29 will drive several groups of particle boards 10 to start rotating. When the second connecting ring 29 moves to the lowermost end, several groups of particle boards 10 are set in the annular groove 9 and rotate;

[0041] At this time, the scale entering the annular groove 9 is broken up by several groups of particle boards 10, and the three-way solenoid valve 36 is opened to connect the first drain pipe 11 with a group of second drain pipes 39. At this time, the broken scale passes through the filter plate 8 under the flushing of the water source and enters the first drain pipe 11. The water source with scale passes through the three-way solenoid valve 36 and flows out of the second drain pipe 39. When all the scale is broken up by the particle boards 10, the rotation of the second connecting ring 29 is stopped and driven back to the upper end of the water tank body 1. At this time, the descaling in the water tank body 1 is completed.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

6. A descaling method for an air energy water tank descaling device according to any one of claims 1 to 5, characterized in that: The following steps are involved: S1. Turn on the motor (17) to move the first connecting ring (4) upward along the support tube (34). When the connecting tube (37) is fully inserted into the water tank body (1), add the prepared cleaning liquid into the liquid storage chamber (30) through the connecting tube (37). After the addition is completed, the connecting tube (37) enters the water tank body (1). The control transmission gear (32) drives the second connecting ring (29) to rotate counterclockwise, and the arc plate (2) is driven to start rotating to one side. The support block (28) rotates and drives the lever (21) to start moving, so that the blocking plate (22) is stored in the storage groove (20); S2. The cleaning liquid in the liquid storage chamber (30) falls from the liquid guide groove (27) onto the scale surface to soften the scale. The first connecting ring (4) is controlled to move to the upper end and the second connecting ring (29) is controlled to rotate clockwise. The first connecting ring (4) is controlled to move downward. Under the rotation of the plurality of sets of arc plates (2), the scale falls off from the inner wall of the water tank body (1). The plurality of sets of arc plates (2) rotate downward to evenly scrape off the scale on the surface of the water tank body (1). The external water source brings the scraped scale into the annular groove (9). Driven by the second connecting ring (29), the plurality of sets of chipping plates (10) break up the scale. S3. Open the three-way solenoid valve (36) to connect the first drain pipe (11) with a set of second drain pipes (39). The broken scale passes through the filter plate (8) under the flushing of the water source and enters the first drain pipe (11). The water source with scale passes through the three-way solenoid valve (36) from the second drain pipe (39). When all the scale is broken by the particle board (10), stop the rotation of the second connecting ring (29) and drive it back to the upper end of the water tank body (1).
