Description

Technical Field

[0001] The utility model relates to a filter element, in particular to an air purifier filter element. Background Art

[0002] The filter element is a very important component in the air purifier. With the use of the air purifier, the filtering effect of the filter element will gradually decrease. Therefore, in order to ensure the use effect of the air purifier, the filter element also needs to be replaced regularly. In addition, in order to improve the filtering effect of the air purifier, the current filter element also uses activated carbon and filter paper. After the air passes through the filter paper, it is adsorbed by the activated carbon to improve the purification effect. Activated carbon and filter paper are also filter materials that need to be replaced regularly. At present, this type of filter element is to simply bond the activated carbon box and the filter paper box to the same shell, and then install the shell on the air purifier. There are still problems: the activated carbon box and the filter paper box cannot be replaced separately, and the use cycle of the two is different under general use conditions, which causes a certain amount of waste and is not conducive to the effective use of resources.

[0027] See also Figure 1 and Figure 2 , an air purifier filter element, comprising a shell 1, an activated carbon box 2, a filter paper box 3 and two connecting belts 4.

[0028] The housing 1 is cylindrical, wherein the edge of the circular opening on the first side has a first flange 1a facing inwards, that is, the first flange 1a is annular and can be integral with the housing 1 and formed by injection molding.

[0029] The activated carbon box 2 is detachably fixedly connected to the housing 1, and the first side of the activated carbon box 2 abuts against the first flange 1a of the housing 1. That is, the first flange 1a is used to position and fix the activated carbon box 2.

[0030] The filter paper box 3 is detachably fixedly connected to the housing 1 in a rotating manner.

[0031] The first ends of the two connecting belts 4 are respectively fixedly connected to two opposite positions of the filter paper box 3, and the second ends are exposed outside the housing 1. When the filter paper box 3 is installed or removed, the filter paper box 3 is rotated by the two connecting belts 4.

[0032] See also Figure 3 , Figure 4 and Figure 5, optionally, a first detachable manner of the activated carbon box 2 and the filter paper box 3: the inner wall of the shell 1 is divided into a first section 1b and a second section 1c, the inner diameter of the first section 1b is relatively smaller and has a first internal thread; the outer wall of the activated carbon box 2 has a first external thread matching the first internal thread, that is, the activated carbon box 2 is detachably fixedly connected to the shell 1 through the thread, and when the activated carbon box 2 is installed to the shell 1, the activated carbon box 2 is rotated until the first side of the activated carbon box 2 is against the first flange 1a; the edge of the second side of the activated carbon box 2 relative to the first side has The third flange 2a is pointed outwards, and there are several notches 2a1 on the third flange 2a; the filter paper box 3 has several connecting parts 3a that fit into the notches 2a1. Specifically, the cross section of the connecting part 3a is L-shaped, that is, after the activated carbon box 2 is installed in the shell 1, the several connecting parts 3a of the filter paper box 3 are first aligned with the several notches 2a1 on the activated carbon box 2, and then the filter paper box 3 is inserted into the shell 1 until the first side of the filter paper box 3 is against the second side of the activated carbon box 2, and finally the filter paper box 3 is rotated so that the connecting parts 3a are offset from the notches 2a1 and clamped on the third flange 2a.

[0033] Correspondingly, when installing or removing the activated carbon box 2, the notch 2a1 on the activated carbon box 2 can be utilized. Specifically, two notches 2a1 among the plurality of notches 2a1 can be opposite to each other. Using a concave tool, the parts on both sides of the notch are respectively inserted into the two notches 2a1, and the activated carbon box 2 is rotated.

[0034] See also Figure 6 , optionally, a second detachable manner of the activated carbon box 2 and the filter paper box 3: the inner wall of the outer shell 1 is divided into a first section 1b and a second section 1c, the second section 1c has a relatively larger inner diameter and has a second internal thread; the outer wall of the filter paper box 3 has a second external thread matching the second internal thread, that is, first insert the activated carbon box into the outer shell 1 until the first side of the activated carbon box 2 is against the first flange 1a, and then rotate the filter paper box 3 to be threadedly connected to the outer shell 1 until the first side of the filter paper box 3 is against the second side of the activated carbon box 2.

[0035] In this way, the activated carbon box 2 and the filter paper box 3 can be removed from the housing 1 separately for replacement, and one or both of them can be replaced according to actual usage.

[0036] See also Figure 4 Optionally, the second ends of the two connecting straps 4 and the corresponding positions of the first side surface of the filter paper box 3 are provided with Velcro. In this way, after the filter paper box 3 is installed in the housing 1, the connecting straps 4 can be bent inward and folded, and fixed to the filter paper box 3 by Velcro, so that the two connecting straps 4 are not exposed outside the housing 1, which is more convenient for the subsequent installation between the housing 1 and the air purifier.

[0037] Optionally, the edge of the circular opening on the second side of the housing 1 has a second flange 1d facing outwards. The second flange 1d is provided on the housing 1 to facilitate positioning when installing the air purifier.
