Water pump with noise reduction effect

The invention discloses a water pump with a noise reduction effect, and particularly relates to the technical field of water pumps, a protective shell, a sealing plate and a connecting bottom plate are arranged, a noise reduction layer is a frosted noise reduction plate, and the interior of the noise reduction layer adopts a mode of forming multi-angle groove holes, so that noise generated during operation of a driving motor is spread in the noise reduction plate firstly; when the sound is transmitted to the outside, the sound is transmitted into the multi-angle slot, the multi-angle slot reflects the sound, the sound reflection distance is increased in a multi-angle reflection mode, and when the sound is transmitted to the outside, the sound intensity transmitted to the outside can be greatly reduced due to the fact that the transmission distance is too long. And meanwhile, a sliding sleeve and a sliding plate are matched to assist heat dissipation of the driving motor, so that the noise reduction effect of
