Disclosed are a single-phase permanent magnet rotor electric pump only rotating in a right direction and its realization method. The method comprises the following steps: controlling the size of a water chamber (3) within a water pump body (2) such that a space volume of the water chamber is 3 times or more than that of a space enclosed by each blade (45) of an inner arc water impeller (42) during rotation, and the diameter of the water chamber is 1.2 times or more than that of the water impeller at its common axis; designing the water pump body such that a portion of an inner wall of a water outlet pipe (7) away from the central axis (OO') of the water chamber is parallelly deflected outward in a distance Δ from a tangent of the water chamber inner wall (31), thereby establishing a step structure (6); selecting a single-phase permanent magnet rotor or a proper torque to drive the arc water impeller within the water pump body, and limiting the fluctuation range of power supply voltage, thus ensuring that electric water pump rotates only in a right rotation direction and against the bending direction of the individual water blade. This method enables the water pump to rotate in the right direction under single-phase AC power supply condition where the fluctuation is up to 20% of the rated voltage.

The present invention relates to the method for preventing the liquid in the filtering plug-in card form dripping and a plug-in-card type liquid purifying and filtering device. The said liquid purifying and filtering device comprises the water pump, filtering cylinder and filtering plug-in card. In particular, at the top of the said filtering cylinder is equipped with the disassembled filtering plug-in card retainer. When the filtering plug-in card is taken out, such disassembled filtering plug-in card retainer is utilized to place the said filtering plug-in card, thus enabling such filtering plug-in card to leave the liquid level inside the filtering cylinder. In addition, it can set the disassembled top cap retainer for the said filtering cylinder. When the said top cap is disassembled, the disassembled top cap retainer is used to place the said top cap. In the course of replacing the said filtering plug-in card in the present invention, the liquid attached to the filtering plug-in card and liquid attached to the underside of the top cap are refluxed into the filter cylinder or water body, thus effectively preventing the liquid from dripping during the replacement of the filtering plug-in card and enabling the process of replacing the filtering plug-in card to be clean, simple and convenient.
