In order to improve the service life of the motor end cover and slow down the corrosion of the motor end cover, a layer of paint needs to be electrophoretically coated on the motor end cover during the production process. In the prior art, the utility model patent with the patent application number 202322457995.1 discloses an electrophoretic spraying device for an automobile swing arm, which mainly includes an electrophoretic paint liquid pool, a support rod, an installation cover, etc. When electrophoretically coating an object, first, electrophoretic paint is added into the electrophoretic paint liquid pool and mixed with a diluent, then the object to be coated is immersed in the electrophoretic paint liquid pool, and then an external electric field is applied to the electrophoretic paint liquid pool, so that the electrophoretic paint adheres to the surface of the object under the action of the electric field to complete the coating; the inventor believes that there are the following problems in the use process. When the electrophoretic paint is mixed with the diluent, it only relies on its own diffusion effect to mix with the diluent, not only the mixing speed is low, but also the mixing effect is not good, which affects the electrophoretic coating efficiency of the object, is inconvenient to use, and has poor practicability. Summary of the Utility Model
