[0032] The following is combined with Figures 1 to 2 to describe the filter device of the present utility model.

[0033] As Figure 1 shown, an embodiment of the first aspect of the present utility model provides a filter device, including a frame 1, a filter component 2 and a clamping member 3.

[0034] Specifically, the frame 1 is used for being fixedly installed at the target air return opening and can serve as a support for the filter component 2.

[0036] At least one edge of the filter component 2 is inserted into the frame 1, the clamping member 3 is arranged on the frame 1, and the clamping member 3 is clamped with the remaining edges of the filter component 2.

[0037] With such a setting, the frame 1 is fixedly arranged at the target air return opening, and the filter component 2 is detachably installed on the frame 1 in the form of insertion and clamping. The structure is simple. And when the filter needs to be maintained, only the filter component 2 needs to be removed from the frame 1. The mass of the filter component 2 is small, the labor intensity of the operator is low, and the structure forms of insertion and clamping are convenient for disassembly and assembly, which is conducive to single-person one-handed operation, solving the problem that the air return opening filter structure in the prior art is bulky and inconvenient for maintenance.

[0038] In an embodiment of the present utility model, at least one edge of the frame 1 is provided with a slot 4 for inserting the edge of the filter element assembly 2.

The connecting plate is fixedly connected to the frame 1. The plug-in plate is parallel to the plane of the frame 1. There is a spacing between the plug-in plate and the surface of the frame 1 close to the plug-in plate, and this spacing forms the slot 4. The edge of the filter element assembly 2 is used to be inserted into the space between the plug-in plate and the frame 1.

[0040] In this embodiment, the frame 1 is rectangular. A slot 4 is provided on one edge of the frame 1, and clamping members 3 are respectively provided on the other three edges of the frame 1.

[0041] When installing the filter element assembly 2 on the frame 1, first insert one edge of the filter element assembly 2 into the slot 4 on the frame 1, and then operate the clamping members 3 located on the other edges of the frame 1 to make each clamping member 3 engage with the filter element assembly 2, so as to realize the installation of the filter element assembly 2 on the frame 1.

[0042] When it is necessary to remove the filter element assembly 2 from the frame 1, the clamping members 3 can be operated first to make each clamping member 3 disengage from the filter element assembly 2, and then the filter element assembly 2 can be pulled to make the filter element assembly 2 disengage from the slot 4 on the frame 1, so that the filter element assembly 2 can be removed from the frame 1.

[0043] Specifically, the slot 4 can extend from one end to the other end of the edge of the frame 1 where it is located, so that the whole edge of the filter element assembly 2 is inserted into the slot 4 of the frame 1, which can improve the reliability of the plug-in structure between the filter element assembly 2 and the frame 1 and improve the stability of the filter element assembly 2.

[0044] In this embodiment, among the other three edges of the frame 1, that is, among the edges of the frame 1 where the slot 4 is not provided, at least two clamping members 3 are correspondingly provided on each edge.

[0045] With such a setting, each edge of the filter element assembly 2 is clamped to the frame 1 by at least two clamping members 3, and the filter element assembly 2 is supported at multiple positions, which can improve the flatness of the filter element assembly 2, improve the connection conformity between the filter element assembly 2 and the frame 1, and improve the filtering effect of the filter device.

[0046] In a further embodiment, an elastic layer 5 is provided on one of the edge of the filter element assembly 2 and the inner wall of the slot 4, so that when the edge of the filter element assembly 2 is inserted into the slot 4, the edge of the filter element assembly 2 is in interference fit with the slot 4, which can improve the stability of the connection structure between the filter element assembly 2 and the frame 1 and avoid the problem that the filter element assembly 2 is disengaged from the plug-in connection with the frame 1 due to vibration.

[0050] The fixing portion is fixedly arranged on the frame 1, and the bolt portion faces the central position of the frame 1. When the bolt portion retracts into the interior of the fixing portion, the filter screen assembly 2 can move relative to the frame 1 to realize the disassembly and assembly of the filter screen assembly 2 on the frame 1.
