This invention relates to a magnetic limit unlocking assembly and an electric door closer including the same. The limit unlocking assembly includes a limit bracket, a rotating block, a permanent magnet, and a force-relieving retaining mechanism. The rotating block is pivotally connected to the inner cavity of the limit bracket. A limit end protruding to the left is provided on the lower left side of the rotating block. A limit groove cooperating with the limit end is provided on the left wall of the inner cavity of the limit bracket. An electromagnet is fixed on the right side of the rotating block. An arc groove is provided on the top surface of the rotating block. The force-relieving retaining mechanism includes a force-relieving spring and a ball bearing. The advantages of this invention are: the permanent magnet is directly fixed to the slider and engages with the unenergized electromagnet when locked in the limit position, meaning no power is consumed in the normally open state, saving energy; and the limit position is automatically engaged when the door is fully open, making it convenient to use. The newly designed force-relieving retaining mechanism reduces the impact of forced opening on the fixed pin, and the force-relieving spring prevents the rotating block from jamming, avoiding unexpected situations where forced opening fails. The improved structure is simpler, with fewer parts, reducing costs.

This invention discloses a method and implementation device for storing water in a smart toilet tank. An air storage chamber is provided at the bottom of the cleaning tank. The cleaning tank is built into the flushing tank and located below the float of the inlet valve. Before the initial water storage, water fills the cleaning tank and overflows downwards into the flushing tank. The cleaning tank floats on the surface of the flushing tank and rises with it. Finally, the cleaning tank causes the float of the inlet valve to rise, thereby closing the inlet valve. When only the flushing tank is replenished with water, the rising water level in the flushing tank causes the cleaning tank to float, which in turn causes the float of the inlet valve to rise, thus closing the inlet valve. Similarly, when only the cleaning tank is replenished with water, the rising water level in the cleaning tank causes the float of the inlet valve to rise, thereby closing the inlet valve. By placing the cleaning tank inside the flushing tank, the smart toilet seat can save installation space for the cleaning tank, allowing for a thinner smart toilet seat.
