US 9,307,748 B2 · Method for preventing filtering plug-in card from dripping liquid and plug-in-card type liquid purifying and filtering device

Abstract

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.
