[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figures 1 to 4As shown, this embodiment includes a pump cover 1, a pump body 2, an outer shell 3, a control element 4 and a coil group 7. There are two pump covers 1 and the two pump covers 1 are fixedly installed on both sides of the pump body 2. The outer shell 3 is fixed to the outside of the pump body 2. The surface of the pump body 2 is provided with a plurality of arc grooves 21 in a circumferential array. The length of the arc groove 21 is the same as that of the pump body 2, that is, the arc groove 21 runs through both ends of the pump body 2. The control element 4 is placed at the bottom of the arc groove 21. Specifically, the control elements 4 are placed at intervals. A convex body 22 is formed on both sides of each arc groove 21. A limit bar 5 is installed between the convex bodies 22. The limit bar 5 are also arranged at intervals. The limit bar 5 is installed at the upper end of the arc groove 21 without the control element 4. The fixing bolt 6 passes through the limit bar 5 and fixes the limit bar 5 to the surface of the pump body 2. The two ends of the limit bar 5 extend into the two sides of the arc groove 21 and fit with the bottom of the two sides of the arc groove 21. The two feet of the limit bar 5 are provided with a limit groove 51. The control element 4 extends into the limit groove 51 so that the control element 4 is fixedly connected to the limit bar 5. The coil group 7 is placed in the arc groove 21 at the bottom of the limit bar 5. A limit block 52 is formed at the bottom of the limit bar 5. The coil group 7 is sleeved on the limit block 52 so that the coil group 7 and the limit bar 5 are fixed.

[0019] like Figures 1 to 3 As shown, the control element 4 has an element pin 41 extending therefrom, and the coil has a coil pin 71 extending therefrom. Mounting rings 31 are formed on both sides of the outer shell 3. Bolt holes 32, element holes 33 and coil holes 34 are provided on the mounting ring 31. The element pin 41 and the coil pin 71 extend out of the outer shell 3 through the element hole 33 and the coil hole 34 respectively. The element pin 41 and the coil pin 71 extending out of the element hole 33 and the coil hole 34 can be connected to the external water pump controller and the motor respectively. The long bolt 8 is respectively passed through the bolt hole 32, the pump cover 1 and the protrusion 22 on the outer shell 3. The fastening nut 9 is fixed to both ends of the long bolt 8 and the fastening nut 9 is in contact with the outer side of the mounting ring 31. The long bolt 8 and the fastening nut 9 fix the outer shell 3, the pump cover 1 and the pump body 2 in connection.

[0020] To elaborate further, Figure 2 As shown, the limiting block 52 is in contact with the bottom of the arc-shaped slot 21 . This structure prevents the coil assembly 7 from falling out of the limiting block 52 .

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
