By arranging multiple cavities with gradually decreasing cross-sectional areas in the liquid storage tank, the water flow dynamics in the liquid storage tank is optimized, the water flow is guided to form a directional vortex, the bottom water accumulation is avoided, the water flow near the water outlet 160 is ensured to continuously flow, the impurities are inhibited from adhering, the impurities are reduced to deposit, and the inside of the water tank is kept clean; meanwhile, the bottom concentrated stress can also be avoided, and the service life of the liquid storage tank is prolonged.
