Technical Field

[0001] The utility model relates to a filter material, in particular to a plate-frame filter element. Background Art

[0002] Filter elements are generally used in various electrical appliances such as vacuum cleaners and air conditioners. They have a variety of different shapes such as cylindrical and rectangular frames according to different usage scenarios. The filter element generally includes a frame part of the corresponding shape and a filter part made of filter paper or filter cloth, and then the two are fixedly connected. For the plate and frame filter element, the whole is cubic, and the frame part is generally divided into four sections. The cross-section is concave, and the two ends are chamfered and wrapped around the filter part for fixing. There are still problems with this setting of the filter element: when installing it to the filter part, the positioning requirements are relatively high, the operation is relatively inconvenient, and the four sections are easy to misalign.

[0026] Please refer to Figure 1 , a plate and frame filter element, comprising a frame part 1 and a filtering part 2.

[0027] See also Figure 2 The frame portion 1 includes a base portion 1a, two first bent portions 1b and two second bent portions 1c.

[0028] The base 1 a is in a rectangular frame shape and has four edges, two opposite edges of which are marked as first edges and the remaining two opposite edges are marked as second edges.

[0029] The two first bends 1b are respectively connected to the two first edges of the base 1a, and the two second bends 1c are respectively connected to the two second edges of the base 1a. In addition, the first bend 1b and the second bend 1c are identical in structure, both including a vertical plate 3 and a horizontal plate 4, and the difference between the first bend 1b and the second bend 1c is only that the lengths of the first edge and the second edge may be different, resulting in different lengths of the first bend and the second bend 1c. Specifically, the entire frame portion 1 can be integral, and the unfolded shape is cut out by cardboard, and indentations are pressed on the first and second edges of the base 1a, and the bends are bent along the indentations to form the above-mentioned first bend 1b and second bend 1c; indentations are also pressed on the first bend 1b and the second bend 1c, and the bends are bent along the indentations to form the above-mentioned vertical plate 3 and horizontal plate 4.

[0030] See also Figure 4 The filter part 2 includes a plurality of first frames 2a and filter paper 2b. The filter paper 2b is arranged along the first frames 2a, that is, the filter paper 2b is bent back and forth to form a zigzag shape, and the filter paper 2b is shaped by the first frames 2a to keep the shape.

[0031] See also Figure 5 and Figure 6 Optionally, the first skeleton 2a includes a first frame 2a1 and a second frame 2a2. The first frame 2a1 is connected to the first surface of the filter paper 2b close to the base 1a, and the second frame 2a2 is connected to the second surface of the filter paper 2b opposite to the first surface. In this way, the first frame 2a1 and the second frame 2a2 are used as a first skeleton 2a, which has a corresponding shaping effect on both sides of the filter paper 2b, so that the filter paper 2b can maintain the desired shape more stably.

[0032] The base 1a is fixedly connected to the first surface of the filtering portion 2. Specifically, the two can be bonded and fixed with glue. Combined with the above-mentioned "first skeleton 2a includes a first frame body 2a1 and a second frame body 2a2", glue is applied to the first frame body 2a1. For the first frame bodies 2a1 on both sides, glue can be applied all over. For the first frame body 2a1 in the middle, glue can be applied only at the two end positions.

[0033] The vertical plates 3 of the two first bent portions 1b and the two second bent portions 1c are respectively fixedly connected to the four side walls of the filter portion 2. Specifically, for the two vertical plates 3 of the first bent portion 1b, the serrated side edges of the filter paper 2b are coated with glue for bonding; for the two vertical plates 3 of the second bent portion 1c, the bending angles of the two sides of the filter paper 2b are controlled so that the filter paper 2b on these two sides are vertical, and glue is coated for bonding.

[0034] The horizontal plates 4 of the two first bending parts 1b and the two second bending parts 1c are respectively fixedly connected to the second surface of the filter part 2 relative to the first surface. That is, firstly, the vertical plates 3 of the first bending parts 1b and the two second bending parts 1c are bonded and fixed to the filter part 2; then, glue is applied to the second surface of the filter part 2, combined with the above-mentioned setting of "the first skeleton 2a includes the first frame body 2a1 and the second frame body 2a2", and glue is applied to the second frame body 2a2. For the second frame bodies 2a2 on both sides, glue can be applied to all of them, and for the second frame body 2a2 in the middle, glue can be applied only to the two ends; finally, the horizontal plates 4 of the two first bending parts 1b and the two second bending parts 1c are bent.

[0035] See also Figure 2 and Figure 3 Optionally, the vertical plates 3 of the two second bending portions 1c are provided with a plurality of protrusions 1c1, and each protrusion 1c1 is provided with a slot for inserting parts of the filter paper 2b on both sides.

[0036] In this way, when bonding the filter part 2 and the vertical plate 3 of the two second bending parts 1c, the vertical plate 3 of the two second bending parts 1c can be bent to be perpendicular to the base 1a first, and then the filter part 2 can be coated with glue and inserted until it is against the base 1a.

[0037] Furthermore, when the vertical plates 3 of the two second bent portions 1c are perpendicular to the base 1a, the plurality of protrusions 1c1 abut against the base 1a.

[0038] In this way, it is convenient to position the two second bent parts 1c, and glue can be applied between the multiple protrusions 1c1 and the base 1a for bonding and fixing, so that the vertical plates 3 of the two second bent parts 1c remain perpendicular to the base 1a, which is more convenient for the subsequent insertion of the filter part 2.

[0039] See also Figure 2 and Figure 3 Optionally, the vertical plates 3 of the two first bent portions 1b are each provided with a third frame 1b1, and the third frame 1b1 matches the first surface of the filter paper 2b. Specifically, the third frame 1b1 may be the same as the first frame 2a1. In combination with the above-mentioned setting of "the first frame 2a includes the first frame 2a1 and the second frame 2a2", for the first frames 2a1 on both sides, a spacing is left between each first frame 2a1 and the serrated side edge of the filter paper 2b on the same side, for the third frame 1b1 to match.

[0040] Similarly, when bonding the filter part 2 and the vertical plates 3 of the two first bending parts 1b, the vertical plates 3 of the two first bending parts 1b can be bent to be perpendicular to the base 1a first, and then the filter part 2 is coated with glue and inserted until it is against the base 1a.

[0041] Furthermore, when the vertical plates 3 of the two first bent portions 1b are perpendicular to the base 1a, the third frame 1b1 abuts against the base 1a.

[0042] In this way, it is convenient to position the two first bent portions 1b, and glue can be applied between the third frame 1b1 and the base 1a for bonding and fixing, so that the vertical plates 3 of the two first bent portions 1b remain perpendicular to the base 1a, making it easier to insert the subsequent filter part 2.
