In the present embodiment, noise reduction of the booster pump is implemented in two aspects, one of which is to add the noise reduction structure 3, the noise reduction structure 3 is disposed in the second chamber 102 and is arranged away from the opening of the second chamber 102, and specifically includes at least two vibration-stopping plates 31 whose peripheries are connected to the inner wall of the housing 2, and each vibration-stopping plate 31 is arranged at intervals in the axial direction of the housing 2, and a vibration-damping cavity 30 is formed between two adjacent vibration-stopping plates 31. Specifically, each of the shock absorbing plates 31 is provided with a through hole 32 for passing the wire harness, and the peripheral edge of each through hole 32 extends to one side of the shock absorbing plate 31 to form a flange 33. Each flange 33 in this embodiment extends downward to form a vertically extending and sequentially connected line concentration channel as a whole, but the connection here may be direct contact or leave a certain gap, and the flanges 33 in this embodiment are connected with each other with a gap, and the line concentration holes 21 are arranged at the tail end of the line concentration channel.
