Furthermore, a plurality of water outlet holes 401 are formed in the pipe wall of the inner flow pipe 4 outside the driving box 3, and a driving assembly for driving the inner flow pipe 4 to rotate is arranged in the driving box 3; when normally adding water to water tank 1, need not to start drive assembly, interior flow tube 4 also does not take place to rotate, and water enters into interior flow tube 4 after entering conical tube 5 from cold water pipe 2 again, then flows out to in the water tank 1 from apopore 401. When the water tank 1 needs to be cleaned, the driving assembly is started, the driving assembly drives the inner flow pipe 4 to rotate, and when water in the inner flow pipe 4 flows out of the water outlet hole 401, the water is sprayed far due to the action of centrifugal force, so that the inner side wall of the water tank 1 can be washed; furthermore, because the diameter of interior flow tube 4 is less than the diameter of cold water pipe 2, therefore, water pressure grow when cold water pipe 2 enters into interior flow tube 4 through toper pipe 5, thereby make the pressure grow of interior flow tube 4 normal water, the jet distance of water has further been increased, improve the washing effect, after water tank 1 washs, the water in the water tank 1 can be discharged from the blow off pipe (blow off pipe and water tank 1's bottom intercommunication, not shown in the figure, be equipped with the blowoff valve on the blow off pipe, the blowoff valve is closed when normal use and clean water tank 1, after water tank 1 washs, open the blowoff valve, can pass through the blow off pipe with the sewage in the water tank 1 and discharge). The cleaning device for the water tank can be used independently, and can also be matched with ultrasonic cleaning for use, so that the cleaning effect of the water tank is improved.

Further, the driving assembly comprises a micro motor 9, an installation plate 8 is fixedly welded on the inner side wall of the driving box 3, the micro motor 9 is installed on the installation plate 8, and an installation block 11 is arranged between the micro motor 9 and the conical tube 5; a first rotating shaft 10 is fixedly arranged on an output shaft of the micro motor 9, one end of the first rotating shaft 10 is connected with the output shaft of the micro motor 9, and the other end of the first rotating shaft 10 is rotatably connected with one side surface, close to the micro motor 9, of the mounting block 11 through a bearing; a first bevel gear 12 is sleeved on the first rotating shaft 10, a second bevel gear 13 is meshed with the top of the first bevel gear 12, a second rotating shaft 14 is arranged at the center of the second bevel gear 13, the top of the second rotating shaft 14 is rotatably connected with the top wall of the interior of the driving box 3 through a bearing, and the bottom of the second rotating shaft 14 is also rotatably connected with the top of the mounting block 11 through a bearing;

the second rotating shaft 14 is further sleeved with a first straight gear 15, the first straight gear 15 is located above the second bevel gear 13, a second straight gear 16 is sleeved outside the inner flow pipe 4, and the first straight gear 15 is meshed with the second straight gear 16. When the micro motor 9 rotates, the first rotating shaft 10 is driven to rotate, so as to drive the first bevel gear 12 to rotate, the first bevel gear 12 rotates to drive the second bevel gear 13 engaged with the first bevel gear to rotate, so as to drive the second rotating shaft 14 to rotate, the second rotating shaft 14 drives the first straight gear 15 sleeved on the second rotating shaft to rotate when rotating, and the first straight gear 15 rotates to drive the second straight gear 16 to rotate, so as to drive the inner flow pipe 4 to rotate.

Further, a first connecting disc 17 is arranged at the bottom of the inner flow pipe 4, a second connecting disc 18 is arranged at the top of the conical pipe 5, the diameter of the first connecting disc 17 is larger than that of the second connecting disc 18, and the first connecting disc 17 is rotatably connected with the second connecting disc 18;

a circle of first sliding groove 19 is formed in the second connecting disc 18, and a first sliding sealing ring 20 is installed in the first sliding groove 19; the first connecting disc 17 and the second connecting disc 18 can be connected in a rotating mode through a sliding block and a circular sliding rail, and details are not repeated here, and the first sliding sealing ring 20 can ensure that the first connecting disc 17 is connected with the second connecting disc 18 in a rotating mode and seals the first connecting disc 17 and the second connecting disc 18.

When water enters the inner flow pipe 4 from the cold water pipe 2 through the conical pipe 5, an upward impact force is generated on the inner flow pipe 4, so that the sealing effect of the first sliding seal ring 20 cannot be optimal, therefore, an L-shaped connecting plate 21 is welded and fixed inwards at the bottom edge of the first connecting plate 17, the second connecting plate 18 is clamped between the first connecting plate 17 and the L-shaped connecting plate 21, the bottom surface of the second connecting plate 18 is in contact with the inner side surface of the L-shaped connecting plate 21, a circle of second sliding groove 22 is formed in the inner side surface of the L-shaped connecting plate 21, a second sliding seal ring 23 is installed in the second sliding groove 22, when the first connecting plate 17 and the inner flow pipe 4 are subjected to the upward impact force, the L-shaped connecting plate 21 is driven to generate an upward acting force, and the position of the second connecting plate 18 is unchanged, therefore, when the L-shaped connecting plate 21 is subjected to the upward acting force, the second sliding seal ring 23 is pressed, so that the sealing performance of the second sliding seal ring 23 is enhanced, and the rotary sealing effect between the first connecting disc 17 and the second connecting disc 18 is better.

The working principle of the utility model is as follows: when the water tank is used, water can be normally added into the water tank 1 through the cold water pipe 2, and the water enters the inner flow pipe 4 through the cold water pipe 2 and the conical pipe 5 and is discharged into the water tank from the water outlet hole 401. When needing to wash the inside wall of water tank 1, start micro motor 9, add water in to water tank 1 from cold water pipe 2 simultaneously, micro motor 9 rotates and can drive interior flow tube 4 and rotate to make the water in interior flow tube 4 spray away from apopore 401, wash the inside wall of water tank 1, after water tank 1 washs, sewage accessible blow off pipe discharges.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
