A water tank assembly including a tank body and a one-way valve is provided. The tank body is defined with a clean water cavity communicated with an external pipeline through a water inlet channel, the external pipeline is capable of transporting water to the clean water cavity. The one-way valve is arranged in the water inlet channel and has a first and a second state. During delivering clean water to the clean water cavity, the one-way valve is in the first state to allow water in the external pipeline to be delivered to the clean water cavity, and when clean water is stopped to supply to the clean water cavity, the one-way valve is changed to the second state to restrict the water in the water inlet channel flowing out, such that outflow of the clean water from the water inlet channel is blocked when the external pipeline is removed.

In a shimming method for an irregular object to be examined by magnetic resonant equipment magnetic field parameters are measured at measurement points located on the surface of an irregular object to be examined. Based on the measured magnetic field parameters, the positions and number of shims for adjusting magnetic field homogeneity are calculated when a passive shimming is to be performed, or the current value in a shimming coil are calculated when an active shimming is to be performed, or at the same time both the positions and number of shims and current value in the shimming coil are calculated when active shimming and passive shimming are to be performed at the same time. Shimming is then performed according to the calculated results. These above steps are repeated until achieving required magnetic field homogeneity. Since the homogeneous region is designed to have an irregular shape, it can provide a better coverage of the irregular object to be examined, and at the same time it reduces the shimming constraints to the unnecessary regions outside the irregular object to be examined, therefore avoiding shimming in those unnecessary regions.
