[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Please refer to Figures 1 to 7 .

[0035] The filter screen clamping piece 10 provided in the embodiments of the present application is applied to the air conditioning unit 100, and the air conditioning unit 100 comprises a rack 101 and a water pan 102 arranged in the rack 101. As shown in Figures 1 to 3 , the filter screen clamping piece 10 comprises a bottom plate 11, an inner side plate 12 and an outer side plate 13. The length extension directions of the bottom plate 11, the inner side plate 12 and the outer side plate 13 are the same as the length extension direction of the water pan 102. The inner side plate 12 and the outer side plate 13 are respectively located at the inner side and the outer side of the bottom plate 11 and extend upward to form a clamping groove 14. The clamping groove 14 is used for clamping the lower end of the filter screen assembly 20. As shown in Figure 5 and Figure 6 , the upper end of the inner side plate 12 of the filter screen clamping piece 10 is used for being tightly connected with the water pan 102. The tightly connected means that the two are tightly connected or tightly contacted, or the two are combined with each other. For example, the upper end of the inner side plate 12 and the water pan 102 can be tightly connected through fasteners, or only the upper end surface of the inner side plate 12 and the lower surface of the water pan 102 need to be tightly contacted. In the prior art, there is no connection relationship between the filter screen clamping piece 10 and the water pan 102, and the upper end of the inner side plate 12 is located below the water pan 102, so that a large gap is left between the water pan 102 and the inner side plate 12. The gap is easy to make foreign matters from outside enter. If a large amount of rainwater passes through the filter screen assembly 20, the rainwater will enter the engine room 103 below the water pan 102 through the gap, thereby affecting the operation of the electrical equipment in the engine room 103. The present application is equivalent to increasing the height of the inner side plate 12 relative to the existing filter screen clamping piece 10. Since the inner side plate 12 is connected with the water pan 102, the gap between the water pan 102 and the inner side plate 12 in the height direction is eliminated, so that external foreign matters can be blocked from entering the area below the water pan 102 from the connection position of the inner side plate 12 and the water pan 102.

[0036] It should be noted that the inner side plate 12 of the filter clip connector 10 and the water receiving tray 102 can be connected by fasteners, welding, or sealant bonding, or the inner side plate 12 of the filter clip connector 10 can be integrally formed into the water receiving tray 102. In addition, this utility model is not limited to the above connection methods, and other connection methods can also be used, as long as the two can be connected to avoid a gap between the upper end of the inner side plate 12 and the lower end of the water receiving tray 102.

[0037] In a specific air conditioning unit 100, if the frame 101 is long and requires the installation of many filter assemblies 20, the filter clip 10 can be designed as a multi-segment structure. During installation, each segment can be installed onto the frame 101. This multi-segment structure facilitates transportation and installation, and also reduces bending deformation along the length during manufacturing, thus helping to ensure manufacturing precision. Figure 5 and Figure 6 As shown, the air conditioning unit 100 is provided with two filter clip connectors 10. The right end of the filter clip connector 10 on the left side contacts the left end of the filter clip connector 10 on the right side. The two can simply contact each other or be connected together by fasteners.

[0038] like Figure 4 and Figure 6 As shown, for the end section 16 of the filter clip connector 10 that extends beyond one end of the water receiving tray 102 in the length direction, this end section 16 can maintain its original structure without increasing the height of the inner side plate 12 of the end section 16, for example... Figure 4 and Figure 6 As shown, an avoidance groove is provided between the end section 16 and the main body section of the filter clip connector 10 to avoid the support beam provided at the corresponding position on the frame 101. The upper end of the inner side plate 12 of the end section 16 has an extension plate extending toward the inside of the frame 101. The upper end of the extension plate has a connecting edge, which is connected to a baffle vertically arranged inside the frame 101 by fasteners.

[0039] like Figure 5 and Figure 6 As shown, the filter assembly 20 is installed at the front end and middle position of the frame 101. A lower crossbeam and an upper crossbeam are located at the middle of the front end of the frame 101. The filter clip 10 is connected to the lower crossbeam. Further, a limiting groove 15 can be provided at the junction of the bottom plate 11 and the outer side plate 13 of the filter clip 10. A limiting block corresponding to the limiting groove 15 is provided on the lower crossbeam. Through the engagement of the limiting groove 15 and the limiting block, the installation position of the filter clip 10 can be accurately achieved. To improve the installation stability of the filter assembly 20, a filter upper clip is provided on the upper crossbeam. The filter upper clip is used to engage the upper end of the filter assembly 20. Figure 7As shown, the rear end of the rack 101 is provided with the filter screen clamping piece 10 which is symmetrically distributed with the front end of the rack 101, that is, the front end and the rear end of the rack 101 are respectively provided with the filter screen assembly 20, and the rear end of the rack 101 is also provided with the water receiving tray 102 which is symmetrically distributed with the water receiving tray 102 of the front end. The relative position and connection relationship between the water receiving tray 102 of the rear end and the filter screen clamping piece 10 of the rear end are the same as those between the water receiving tray 102 of the front end and the filter screen clamping piece 10 of the front end.

[0040] In some embodiments, as shown, Figure 1 As shown, the upper end of the inner side plate 12 is provided with the outward turning plate 121, which refers to the structure of the inner side plate 12 outward turning to the outside of the clamping groove 14. The outward turning plate 121 can be formed by outward bending at the upper end of the inner side plate 12, or can be welded at the upper end of the inner side plate 12 or connected to a piece of outward turning plate 121 at the upper end of the inner side plate 12 by fasteners. The outward turning plate 121 is used to tightly contact with the water receiving tray 102, and the two can be in surface-to-surface contact to improve the tightness and stability of the two.

[0041] In some embodiments, the contact relationship between the outward turning plate 121 and the water receiving tray 102 at least exists the following three kinds: first, the upper surface of the outward turning plate 121 is used to contact with the lower bottom surface of the water receiving tray 102, at this time, the height of the inner side plate 12 of the filter screen clamping piece 10 is lower than the height position of the lowermost end of the water receiving tray 102, and the surface-to-surface contact between the outward turning plate 121 and the water receiving tray 102 can improve the connection stability of the two; second, the outer side of the outward turning plate 121 contacts with the outer side of the water receiving tray 102, at this time, the height of the inner side plate 12 of the filter screen clamping piece 10 is higher than the height position of the lowermost end of the water receiving tray 102, but the width of the clamping groove 14 is also relatively narrower than the first kind, or the width of the outward turning plate 121 is relatively narrower than the first kind; third, the outward turning plate 121 tightly contacts with the upper end of the side wall of the water receiving tray 102, for example, the outward turning plate 121 can be overlapped on the upper end of the side wall of the water receiving tray 102, and then the outward turning plate 121 is bent downward to be clamped in the water receiving tray 102; or the outer side of the upper end of the water receiving tray 102 is provided with an outward extending turning edge, and the upper surface of the outward turning plate 121 can tightly contact with the lower surface of the turning edge, or the lower surface of the outward turning plate 121 can tightly contact with the upper surface of the turning edge.

[0042] In some specific application scenarios, due to the different thicknesses of the filter screen assembly 20, filter screen adapters 10 with different slot widths are required to adapt, so that the lateral spacing between the inner side plate 12 and the water receiving tray 102 of the filter screen adapter 10 also differs. Lateral refers to the direction perpendicular to the card slot 14 in the water surface. In addition, for different specifications of the water receiving tray 102, such as water receiving trays 102 of different depths, the height relationship between the water receiving tray 102 and the inner side plate 12 also differs. In order to adapt to the above situation, the inner side plate 12 can be designed as a split structure, for example, the inner side plate 12 includes an inner side base plate and an inner side extension plate. The inner side base plate forms the basic structure of the filter screen adapter 10 with the card slot 14 together with the bottom plate 11 and the outer side plate 13. The inner side extension plate is selected to have an L-shaped structure. The vertical plate of the inner side extension plate can be detachably connected to the inner side base plate by a fastener. The horizontal plate of the inner side extension plate can be tightly connected to the water receiving tray 102. A plurality of different specifications of inner side extension plates can be provided, such as a plurality of vertical plates with different heights and a plurality of horizontal plates with different widths. When the lateral spacing between the water receiving tray 102 and the inner side plate 12 is large, an inner side extension plate with a horizontal plate of large width can be selected to be connected to the inner side base plate.

[0043] In some embodiments, as shown in Figure 1 and Figure 2 The inner side plate 12 is provided with a connecting hole 122, and the water receiving tray 102 is provided with a mounting hole corresponding to the connecting hole 122. During installation, the fastener is inserted into the connecting hole 122 and the mounting hole, thereby achieving the connection between the inner side plate 12 and the water receiving tray 102. The sealing of the connection position should be ensured. Alternatively, the bottom of the water receiving tray 102 is provided with a support, and the support is provided with a mounting hole corresponding to the connecting hole 122. During installation, the fastener is inserted into the connecting hole 122 and the mounting hole on the support. This connection method requires that the upper end of the inner side plate 12 or the outer flange 121 is in contact with the water receiving tray 102. The fastener can be a screw or a pin. By fixedly connecting the inner side plate 12 and the water receiving tray 102, the tightness of the connection between the two can be ensured, so as to avoid the problem of disconnection of the contact relationship between the two due to vibration. In addition, when the inner side plate 12 is long, a plurality of connecting holes 122 can be provided on the inner side plate 12 along the length direction of the inner side plate 12. When the inner side plate 12 is high, a plurality of connecting holes 122 can also be provided on the inner side plate 12 along the height direction of the inner side plate 12, so as to improve the connection stability of the inner side plate 12.

[0044] In some embodiments, the bottom plate 11, the inner side plate 12 and the outer side plate 13 are integrally formed by bending a plate, that is, the filter screen clamping piece 10 can be formed by bending the outer side plate 13, the bottom plate 11 and the inner side plate 12 from a plate, and the outer turning plate 121 at the upper end of the inner side plate 12 can also be formed by bending the plate. By integrally forming the plate, the structural stability of the filter screen clamping piece 10 can be improved, and the manufacturing cost is low, and batch production is facilitated.

[0045] In some embodiments, as shown in Figure 1 The height of the inner side plate 12 is higher than the height of the outer side plate 13, and the filter screen assembly 20 includes a rectangular frame and a filter screen arranged in the rectangular frame, wherein the height of the outer side plate 13 is not higher than the height of the bottom frame of the rectangular frame, so as to avoid affecting the filtering area of the filter assembly. The height of the inner side plate 12 can be higher than the height of the bottom frame of the rectangular frame, and further, in order to avoid affecting the filter assembly, the inner side plate 12 can be bent towards the inside of the air conditioning unit 100 at a position not higher than the bottom frame, and then the inner side plate 12 is bent upwards, that is, the inner side plate 12 is bent twice at right angles. This structure will cause a certain gap between the upper section structure of the inner side plate 12 and the inner side of the filter screen assembly 20, that is, the distance between the upper section structure of the inner side plate 12 and the outer side plate 13 is greater than the distance between the lower section structure of the inner side plate 12 and the outer side plate 13, so as to ensure the air permeability of the filter screen under the effect of the filter screen clamping effect.

[0046] The utility model embodiment further provides a kind of filtering device, including the filter screen clamping piece 10 provided by any one embodiment of above, and filtering device further includes water pan 102, water pan 102 is used to collect the water after air conditioning unit 100 sprinkling system sprinkling, and the inner side plate 12 of filter screen clamping piece 10 is connected with water pan 102, to avoid the water from the space above the inner side plate 12 and below water pan 102 from outside into cabin 103.

[0047] In some embodiments, the filter screen clamping piece 10 and the water pan 102 are integrally formed, wherein the filter screen clamping piece 10 and the water pan 102 can be bent and formed from the same plate. The integrally formed structure can better block the water from the outside from entering the cabin 103 through the filter screen assembly 20.

[0048] In some embodiments, a sealing member is provided between the inner side plate 12 and the water pan 102. For example, after the inner side plate 12 is attached to the outer side of the water pan 102, a sealing member can be provided at the connection position between the two, such as sealing glue at the connection position. In addition, a sealing gasket can be provided between the connection surface of the inner side plate 12 and the water pan 102, and then the inner side plate 12 and the water pan 102 can be reinforced by fasteners.

[0049] The utility model embodiment further provides an air conditioning unit 100, including any one embodiment provided by the filter screen card joint 10, as Figures 5 to 7 The filter screen assembly 20 is fixed on the rack 101, and the lower end of the filter screen assembly 20 is clamped in the clamping groove 14 of the filter screen card joint 10.

[0050] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between the entities.

[0051] The embodiments in the present specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

[0052] The filter screen card joint, the filter assembly and the air conditioning unit are described in detail above.
