  • Patent number: 10376819
    Abstract: A filter core and manufacturing method thereof, the manufacturing method has the following steps: adhering a wavy filtering sheet and a flat filtering sheet, pressing the filtering sheets, and rolling the filtering sheets. A part of peaks of the wavy filtering sheet are pressed to lean toward a same side. In particular, two sides of a first end sealing adhesive layer are pressed. Thus, the first end sealing adhesive layer is concentrated, such that the glue is uniformly spread to the two sides. Besides, the pressing on the two sides makes the two sides of the first end sealing adhesive layer adhered securely, thereby preventing the wavy filtering sheet from rebounding upward and forming bubbles. Thus, the first end sealing adhesive layer can be formed with less quantity of glue, which accelerating the cooling and raises manufacture efficiency.
