It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4As shown, a multi-stage filtering direct drinking water equipment comprises a heating box 1, which is cylindrical, and a mounting ring 8 is arranged inside the heating box 1, and an annular tube 9 is rotatably connected to the outer side of the mounting ring 8, and a drain port is arranged at the bottom of the annular tube 9, and a driving mechanism is arranged between the annular tube 9 and the mounting ring 8, and an input pipe 10 is fixedly connected to the top of the annular tube 9, and the input pipe 10 passes through the outer side of the heating box 1, and an acid liquid tank 5 is fixedly connected to the top of the input pipe 10, and the acid liquid tank 5 is installed on the outer wall of the direct drinking water equipment, and a lifting mechanism is arranged on the inner side of the mounting ring 8. The bottom end of the interior of the heat box 1 is rotatably connected to a cross plate 12, the top of the cross plate 12 is fixedly connected to a docking block 13, the bottom end of the annular tube 9 is fixedly connected to a docking tube 17, and the docking tube 17 cooperates with the docking block 13, the side of the annular tube 9 and the ground of the cross plate 12 are provided with bristles, the bottom of the drain port is fixedly connected to a nozzle 18, and the bottom end of the nozzle 18 faces the inner wall of the heating box 1, the interior of the acid tank 5 is filled with acetic acid with a concentration of 20%, and a water delivery pump is provided, and the inner wall of the heating box 1 and all parts in the heating box 1 are treated with corrosion protection;

[0023] The acid tank 5 inputs acetic acid into the annular tube 9 through the input pipe 10. The acetic acid flows from the drain port on the annular tube 9 to the inner wall of the heating box 1, and flows along the inner wall to the bottom wall. The acetic acid contacts and reacts with the scale in the heating box 1. After a period of reaction, the lifting mechanism works, and the mounting ring 8 and the annular tube 9 move downward along the heating box 1. The side bristles of the annular tube 9 act on the side wall of the heating box 1. As the mounting ring 8 descends, the docking tube 17 is sleeved on the outside of the docking block 13. The driving mechanism makes the annular tube 9 reciprocate forward and reverse on the side of the mounting ring 8, thereby making the cross plate 12 forward and reverse, and the bottom wall of the heating box 1 is cleaned to clean the scale and extend the service life of the equipment.

[0024] Specifically, Figure 2 As shown, the lifting mechanism includes a first motor 6, and the first motor 6 is fixedly installed on the outer wall of the direct drinking water equipment. The output end of the first motor 6 is fixedly connected with a threaded rod 7, and the outer side of the threaded rod 7 is threadedly connected to the mounting ring 8. The bottom end of the threaded rod 7 is at a certain distance from the bottom wall of the heating box 1. The first motor 6 drives the threaded rod 7 to rotate, and the rotating threaded rod 7 drives the mounting ring 8 to move up and down through the thread.

[0025] Specifically, Figure 3As shown, the driving mechanism includes a second motor 14, and the second motor 14 is fixedly connected to the top of the mounting ring 8, an electromagnetic brake is arranged inside the second motor 14, and a gear 15 is fixedly connected to the output end of the second motor 14, and an arc rack 16 is meshed and connected to the outer side of the gear 15, and the arc rack 16 is fixedly connected to the top of the annular tube 9, the arc rack 16 is arc-shaped, and the angle is slightly greater than 90 degrees, and the second motor 14 drives the gear 15 to rotate, and the rotating gear 15 drives the arc rack 16, so that the annular tube 9 rotates on the outer side of the mounting ring 8, and can swing back and forth during the upward movement of the annular tube 9, which is more conducive to cleaning scale, and after the docking block 13 is inserted into the docking tube 17, the swinging annular tube 9 drives the cross plate 12 to swing, and the bottom wall of the heating box 1 can be cleaned, and the docking tube 17 is located below the middle of the arc rack 16, and the second motor 14 finally stays in the middle position of the arc rack 16.

[0026] Specifically, Figure 1 As shown, a connecting pipe 3 is fixedly connected to the bottom right side of the heating box 1, a water pump 2 is fixedly connected to the top of the connecting pipe 3, and the water pump 2 is fixedly installed inside the direct drinking water equipment, and a drain pipe 4 is fixedly connected to the output end of the water pump 2. A solenoid valve is provided at one end of the connecting pipe 3 close to the heating box 1. When the water pump 2 works, the scale and waste acid after the reaction in the heating box 1 are extracted from the heating box 1 and discharged from the drain pipe 4 for easy cleaning.

[0027] Specifically, Figure 2 As shown, a telescopic tube 11 is provided in the middle of the input tube 10 , and the telescopic tube 11 is arranged inside the heating box 1 . The telescopic tube 11 can change its own length to cooperate with the downward movement and swing of the annular tube 9 .

[0028] Working principle: the acid tank 5 inputs acetic acid into the annular tube 9 through the input pipe 10, and the acetic acid flows from the nozzle 18 on the annular tube 9 to the inner wall of the heating box 1, and flows along the inner wall to the bottom wall, and the acetic acid contacts and reacts with the scale in the heating box 1. After a period of reaction, the first motor 6 drives the threaded rod 7 to rotate, and the rotating threaded rod 7 drives the mounting ring 8 to move downward through the thread, and performs preliminary cleaning on the side wall of the heating box 1. When the mounting ring 8 moves to the bottom, the docking block 13 is inserted into the interior of the docking tube 17, and the second motor 14 works to drive the mounting ring 8 to move downward. The moving gear 15 rotates, and the rotating gear 15 drives the arc rack 16, which in turn makes the annular tube 9 rotate on the outside of the mounting ring 8. The swinging annular tube 9 drives the cross plate 12 to swing, so that the bottom wall of the heating box 1 can be cleaned. After the bottom cleaning is completed, the mounting ring 8 returns. During the return, the second motor 14 works again to make the outer wall of the annular tube 9 act on the inner wall of the heating box 1 to deepen the scale removal effect. After the scale removal is completed, clean water is injected into the heating box 1, and the water pump 2 discharges the waste liquid in the heating box 1, and circulates multiple times to make the discharge more thorough.
