DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 7 .

[0024] A filter card connector 10 provided in an embodiment of the present invention is applied to an air conditioning unit 100, the air conditioning unit 100 includes a frame 101 and a water receiving tray 102 arranged in the frame 101, wherein Figures 1 to 3 As shown, the filter screen connector 10 includes: a bottom plate 11, an inner plate 12 and an outer plate 13, wherein the length extension direction of the bottom plate 11, the inner plate 12 and the outer plate 13 is the same as the length extension direction of the water receiving tray 102, and the inner plate 12 and the outer plate 13 are respectively located at the inner side and the outer side of the bottom plate 11 and extend upward to form a slot 14, which is used for the lower end of the filter assembly 20 to be inserted. Figure 5 and Figure 6 As shown, the upper end of the inner plate 12 of the filter clip 10 is used to be in close contact with the water receiving tray 102. Close contact refers to a close connection or close contact between the two, or a way in which the two are combined with each other. For example, the upper end of the inner plate 12 and the water receiving tray 102 can be tightly connected by fasteners, or only the upper end surface of the inner plate 12 needs to be in close contact with the lower surface of the water receiving tray 102. In the prior art, there is no connection between the filter clip 10 and the water receiving tray 102, and the upper end of the inner plate 12 is located below the water receiving tray 102, resulting in a large gap between the water receiving tray 102 and the inner plate 12. This gap makes it easy for foreign matter to enter. If a large amount of rainwater passes through the filter assembly 20, the rainwater will enter the cabin 103 below the water receiving tray 102 through the gap, thereby affecting the operation of the electrical equipment in the cabin 103. Compared with the existing filter clip 10, the present invention is equivalent to increasing the height of the inner plate 12, and because the inner plate 12 is connected to the water receiving tray 102, the gap in the height direction between the water receiving tray 102 and the inner plate 12 is eliminated, so that foreign matter can be prevented from entering the area below the water receiving tray 102 from the connection position between the inner plate 12 and the water receiving tray 102.

[0025] It should be noted that the connection method between the inner plate 12 of the filter clip 10 and the water receiving tray 102 can be through fastener connection, welding, sealant bonding, or the inner plate 12 of the filter clip 10 is integrally formed on the water receiving tray 102. In addition, the present invention is not limited to the above connection method, 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 plate 12 and the lower end of the water receiving tray 102.

[0026] In a specific air conditioning unit 100, if the length of the frame 101 is long and more filter assemblies 20 need to be installed, the filter clip 10 can be designed as a multi-section structure, and each section structure can be installed on the frame 101 during installation. The multi-section structure is convenient for transportation and installation on the one hand, and is convenient for reducing bending deformation in the length direction during manufacturing on the other hand, which is conducive to ensuring its manufacturing accuracy. Figure 5 and Figure 6 As shown, two filter clips 10 are provided on the air conditioning unit 100, and the right end of the left filter clip 10 contacts the left end of the right filter clip 10, and the two may only contact or be connected together by fasteners.

[0027] like Figure 4 and Figure 6 As shown, for the end section 16 of the filter clamp 10 that exceeds one end of the water receiving tray 102 in the length direction, the end section 16 can maintain the original structure without increasing the height of the inner side plate 12 of the end section 16. 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 10 to avoid the support beam provided at the corresponding position on the frame 101, and 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, and the upper end of the extension plate is provided with a connecting edge, which is connected to a baffle vertically provided in the frame 101 by fasteners.

[0028] like Figure 5 and Figure 6 As shown, the front end and the middle position of the frame 101 are used to install the filter assembly 20, wherein a lower crossbeam and an upper crossbeam are provided in the middle of the front end of the frame 101, and the filter clamp 10 is connected to the lower crossbeam. Furthermore, a limiting groove 15 can be provided at the junction of the bottom plate 11 and the outer plate 13 of the filter clamp 10, and a limiting block corresponding to the limiting groove 15 is provided on the lower crossbeam. The installation position accuracy of the filter clamp 10 can be achieved by the clamping of the limiting groove 15 and the limiting block. In order to improve the installation stability of the filter assembly 20, a filter clamp is provided on the upper crossbeam, and the filter clamp is used to clamp the upper end of the filter assembly 20. As shown Figure 7As shown, the rear end of the frame 101 is provided with a filter card connector 10 symmetrically distributed with the front end of the frame 101, that is, the front and rear ends of the frame 101 are respectively provided with filter assemblies 20, wherein the rear end of the frame 101 is also provided with a water receiving tray 102 symmetrically distributed with the water receiving tray 102 at the front end, and the relative position and connection relationship between the water receiving tray 102 at the rear end and the filter card connector 10 at the rear end are the same as the relative position and connection relationship between the water receiving tray 102 at the front end and the filter card connector 10 at the front end.

[0029] In some embodiments, Figure 1 As shown, an outer flap 121 is provided at the upper end of the inner plate 12, and the outer flap 121 refers to a structure on the inner plate 12 that flips outward toward the slot 14, wherein the outer flap 121 can be formed by bending outward at the upper end of the inner plate 12, or can be welded on the inner plate 12, or an outer flap 121 can be connected to the upper end of the inner plate 12 through fasteners, wherein the outer flap 121 is used to be in close contact with the water receiving tray 102, and the two can be in surface contact to improve the close contact stability between the two.

[0030] In some embodiments, there are at least three types of contact relationships between the outer flap 121 and the water receiving tray 102: the first type is that the upper surface of the outer flap 121 is used to contact the lower bottom surface of the water receiving tray 102. At this time, the height of the inner side plate 12 of the filter clamp 10 is lower than the height position of the lowest end of the water receiving tray 102. The outer flap 121 and the water receiving tray 102 are in surface contact, which can improve the connection stability between the two. The second type is that the outer side edge of the outer flap 121 contacts the outer side surface of the water receiving tray 102. At this time, the height of the inner side plate 12 of the filter clamp 10 is higher than the height position of the lowest end of the water receiving tray 102. The outer flap 121 is arranged in a manner that the width of the card slot 14 is narrower than that of the first manner, or the width of the outer flap 121 is narrower than that of the first manner; in the third manner, the outer flap 121 is in close contact with the upper end of the side wall of the water receiving tray 102. For example, the outer flap 121 can be overlapped on the upper end of the side wall of the water receiving tray 102, and then the outer flap 121 can be bent downward to be snapped into the water receiving tray 102; or the outer side of the upper end of the water receiving tray 102 is provided with a flange extending outward, and the upper surface of the outer flap 121 can be in close contact with the lower surface of the flap, or the lower surface of the outer flap 121 can be in close contact with the upper surface of the flap.

[0031] In some specific application scenarios, due to the different thicknesses of the filter assembly 20, filter clips 10 with different groove widths are required for adaptation, which results in differences in the lateral spacing between the inner plate 12 of the filter clip 10 and the water receiving tray 102. The lateral spacing refers to the direction perpendicular to the slot 14 on the water surface. In addition, for water receiving trays 102 of different specifications, such as water receiving trays 102 of different depths, there will also be differences in the height relationship between the water receiving tray 102 and the inner plate 12. In order to adapt to the above situation, the inner plate 12 can be designed as a split structure, for example, the inner plate 12 includes an inner base plate and an inner additional plate, wherein the inner base plate, the bottom plate 11 and the outer plate 13 form the basic structure of the filter clip 10 with a card slot 14, and the inner additional plate selects a structure with an L-shaped cross-section, the vertical plate of the inner additional plate can be detachably connected to the inner base plate by fasteners, and the horizontal plate of the inner additional plate can be in close contact with the water receiving tray 102, wherein a variety of inner additional plates of different specifications can be arranged, for example, a plurality of vertical plates of different heights and a plurality of horizontal plate structures of different widths are arranged, and when the lateral spacing between the water receiving tray 102 and the inner plate 12 is large, an inner additional plate with a larger horizontal plate width can be selected to be connected to the inner base plate.

[0032] In some embodiments, Figure 1 and Figure 2 As shown, the inner plate 12 is provided with a connection hole 122, and the water receiving tray 102 is provided with a mounting hole corresponding to the connection hole 122. During installation, the fasteners are inserted into the connection hole 122 and the mounting hole to achieve the connection between the inner plate 12 and the water receiving tray 102, wherein the sealing of the connection position should be ensured; or a support member is provided at the bottom of the water receiving tray 102, and the support member is provided with a mounting hole corresponding to the connection hole 122. During installation, the fasteners are also required to be inserted into the connection hole 122 and the mounting hole on the support member. This connection method needs to ensure that the upper end of the inner plate 12 or the outer flap 121 is in contact with the water receiving tray 102. The fasteners can be selected as screws or pins. By fixing the inner plate 12 and the water receiving tray 102, the tightness of the connection between the two can be ensured to avoid the problem of separation of the contact relationship between the two due to vibration. In addition, when the inner panel 12 is longer, a plurality of connection holes 122 distributed along its length direction may be provided on the inner panel 12 , and when the inner panel 12 is higher, a plurality of connection holes 122 distributed along its height direction may also be provided on the inner panel 12 , so as to improve the connection stability of the inner panel 12 .

[0033] In some embodiments, the bottom plate 11, the inner plate 12 and the outer plate 13 are formed by bending a plate as a whole, that is, the filter clamp 10 can be bent from a plate to form the outer plate 13, the bottom plate 11 and the inner plate 12, and the outer flap 121 at the upper end of the inner plate 12 can also be bent by this plate. By bending the plate as a whole, the structural stability of the filter clamp 10 can be improved, and the manufacturing cost is low, which is convenient for mass production.

[0034] In some embodiments, Figure 1 As shown, the height of the inner plate 12 is higher than the height of the outer plate 13, and the filter assembly 20 includes a rectangular frame and a filter arranged in the rectangular frame, wherein the height of the outer plate 13 is not higher than the height of the bottom frame of the rectangular frame to avoid the outer plate 13 affecting the filtering area of ​​the filter assembly, wherein the height of the inner plate 12 can be higher than the height of the bottom frame of the rectangular frame. Further, in order to avoid the inner plate 12 affecting the filter assembly, the inner plate 12 can be bent toward the inside of the air-conditioning unit 100 at a position not higher than the bottom frame, and then the inner plate 12 is bent upward, that is, the inner plate 12 is bent at two right angles. This structure will cause a certain gap to exist between the upper structure of the inner plate 12 and the inner side surface of the filter assembly 20, that is, the spacing between the upper structure of the inner plate 12 and the outer plate 13 is greater than the spacing between the lower structure of the inner plate 12 and the outer plate 13, so as to ensure the air permeability of the filter under the effect of the filter clamping effect.

[0035] An embodiment of the present invention also provides a filtering device, including the filter clip 10 provided in any one of the above embodiments, the filtering device also includes a water collecting tray 102, the water collecting tray 102 is used to collect water after being sprayed by the spray system of the air-conditioning unit 100, the inner plate 12 of the filter clip 10 is connected to the water collecting tray 102 to prevent external water from entering the cabin 103 from the space above the inner plate 12 and below the water collecting tray 102.

[0036] In some embodiments, the filter clip 10 and the water tray 102 are integrally formed, wherein the filter clip 10 and the water tray 102 can be bent and formed by the same plate. The integrally formed structure can better prevent external water from entering the cabin 103 from the filter assembly 20.

[0037] In some embodiments, a seal is provided between the inner plate 12 and the water receiving tray 102. For example, after the inner plate 12 is attached to the outer side of the water receiving tray 102, a seal can be provided at the connection position between the two, such as providing a sealant at the connection position. In addition, a sealing gasket can be provided between the connection surfaces of the inner plate 12 and the water receiving tray 102, and then the inner plate 12 and the water receiving tray 102 are reinforced by fasteners.

[0038] The embodiment of the present invention further provides an air conditioning unit 100, comprising the filter card connector 10 provided in any one of the above embodiments, such as Figures 5 to 7 As shown, the filter clamp 10 is fixed on the frame 101, and the lower end of the filter assembly 20 is clamped in the clamping groove 14 of the filter clamp 10. For the beneficial effects of the air conditioning unit 100, reference can be made to the filter clamp 10 in the above embodiment, which will not be repeated here.

[0039] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0040] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
