[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-5As shown, a water pump with a circulating liner includes a pump body 1, a water inlet interface 2 and a drain interface 3, and also includes a circulating liner 6, a metal heating plate 7 and a filter sleeve 13. The water inlet interface 2 and the drain interface 3 are respectively fixedly arranged at the top and bottom of both sides of the pump body 1. An impeller 5 is arranged in the pump body 1, and the impeller 5 is located between the water inlet interface 2 and the drain interface 3. The circulating liner 6 is arranged on the top of the impeller 5, and the periphery of the circulating liner 6 is welded to the inner wall of the pump body 1. The metal heating plate 7 is fixedly arranged on the top of the circulating liner 6, and the controller of the metal heating plate 7 is arranged on the outside of the pump body 1.

[0020] Among them, a water inlet 8 is opened at the bottom of one side of the circulation inner tank 6, and a drain port 9 is opened on the other side of the circulation inner tank 6. The water inlet 8 and the drain port 9 are communicated with each other. A return water port 10 is set at the bottom of the drain port 9. The water inlet end of the return water port 10 is connected to the drain port 9, and the drain end of the return water port 10 is connected to the water inlet 8. A one-way valve 11 is fixedly set in the inner cavity of the return water port 10. The diameters of the drain port 9 and the return water port 10 are both smaller than the diameter of the water inlet 8. The drain port 9 is connected to the drain interface 3; the one-way valve 11 can allow the water flow inside the return water port 10 to flow in only one direction.

[0021] A motor 4 is fixedly mounted on the top of the pump body 1 , and a driving shaft of the motor 4 is fixedly connected to the impeller 5 .

[0022] The pump body 1 has a threaded socket 12 at the bottom, the filter sleeve 13 is inserted into the bottom of the pump body 1 , and the bottom of the filter sleeve 13 is threadedly connected to the threaded socket 12 . The outer periphery of the filter sleeve 13 is welded with a metal filter mesh sleeve 14 .

[0023] Among them, a drainage socket 15 is provided on the top of the filter sleeve 13, and the drainage socket 15 is in contact with the inner wall of the pump body 1. The filter sleeve 13 is a birdcage structure, and a hexagonal groove 16 is provided at the bottom of the filter sleeve 13; the hexagonal groove 16 is convenient for personnel to rotate and remove the filter sleeve 13 with a hexagonal wrench, so that personnel can clean and maintain the periphery of the filter sleeve 13 and the bottom of the inner cavity of the pump body 1.

[0024] It should be noted that the utility model is a water pump with a circulation inner tank. When working, the personnel connect the water inlet interface 2 and the drainage interface 3 of the water use site to the drainage pipe and the water supply pipe, and use the power supply mechanism around the use site to provide power for the electrical components in this application. The motor 4 drives the impeller 5 to suck the bottom of the pump body 1, so that the external water source can be sucked in through the water inlet interface 2. After the external water source enters the water inlet interface 2, it will be filtered by the metal filter sleeve 14 and then enter the filter sleeve 13. The filtered water source is discharged from the top of the drainage socket 15 of the filter sleeve 13, and after passing through the ring inner tank 6, it is discharged from the drainage socket 15 to the top. The interface 3 is discharged to the outside. When the water source needs to be heated, the top of the circulation tank 6 can be heated by the metal heating plate 7, so that the water source flowing out of the top drain port 9 in the circulation tank 6 can be heated. Through the small-diameter arrangement of the drain port 9 and the return port 10, after the water source enters the water inlet 8, the water source entering the water inlet 8 cannot be completely discharged from the drain port 9, so that part of the water source will flow back to the water inlet 8 through the return port 10, so that part of the water source can be internally circulated, and the water source can be fully heated in the circulation tank 6, so that the heating efficiency of the discharged water source is greatly improved, which is suitable for use in equipment with certain requirements on water quality and water use temperature.
