Therefore, they should not be construed as limiting this invention.

[0066] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] The evaporative cooling pad assembly of an air cooler is generally located inside the unit and protected by a grille or rear mesh. The evaporative cooling pad needs to be cleaned regularly. The components that support the evaporative cooling pad generally adopt a fixed installation structure. For example, the evaporative cooling pad bracket is fixed to the support ring by bolts or adhesive. This leads to the following problems when disassembling: 1. The disassembly process is cumbersome, requiring multiple tightening of bolts or damage to the adhesive layer, resulting in low maintenance efficiency; 2. Repeated disassembly can easily cause thread wear or structural deformation, reducing assembly accuracy.

[0068] Based on this, the following embodiments are proposed:

[0069] Example 1

[0070] like Figure 1 , 2 As shown, this embodiment provides a support assembly for an evaporative cooling pad, including:

[0071] A first support frame 1 is provided with a plurality of first connectors 2 distributed circumferentially on the first support frame 1;

[0072] The second support frame 3 is used to support the wet curtain, and the second support frame 3 is provided with a plurality of second connectors 4 distributed circumferentially.

[0073] Each of the second connectors 4 corresponds one-to-one with a plurality of the first connectors 2;

[0074] Wherein, the second connecting member 4 rotates relative to the first connecting member 2 in a first direction, the second connecting member 4 engages with the first connecting member 2 to connect the second support frame 3 to the first support frame 1, the second connecting member 4 rotates relative to the first connecting member 2 in a second direction opposite to the first direction, and the second connecting member 4 separates from the first connecting member 2 to disassemble the second support frame 3 from the first support frame 1.

[0075] In this embodiment, the support assembly can be adapted and installed with various appliances as needed, such as air coolers. The support assembly includes a first support frame 1 and a second support frame 3. One or more first connectors 2 are provided on the first support frame 1, and one or more second support frames are provided on the second support frame 3. The number of first support frames 1 and second support frames 3 is the same, so that each first support frame 1 corresponds to a second support frame 3 that can cooperate with it. The first support frame 1 and the second support frame 3 can be connected to each other and can also be disassembled and separated.

[0076] For example, when the second support frame 3 needs to be installed on the first support frame 1, first keep the first support frame 1 and the second support frame 3 parallel and close together. Then, tilt the second support frame 3 slightly so that one side is up and the other side is down. Then, move the second support frame 3 relative to the first support frame 1 in the first direction. The second connecting piece 4 gradually moves closer to the first connecting piece 2 as the second support frame 3 moves. After the second connecting piece 4 and the first connecting piece 2 are connected, the second support frame 3 can no longer move relative to the first support frame 1. At this time, the first support frame 1 and the second support frame 3 are assembled.

[0077] When it is necessary to detach the second support frame 3 from the first support frame 1, the second support frame 3 is moved in a second direction relative to the first support frame 1. The second connecting piece 4 gradually moves away from the first connecting piece 2 as the second support frame 3 moves, until the second connecting piece 4 is completely separated from the first connecting piece 2. At this point, the second support frame 3 is also completely separated from the first support frame 1, and the detachment of the first support frame 1 and the second support frame 3 is complete. The first direction and the second direction can be completely opposite directions, or they can be two different directions, as long as the effect of installation and detachment of the first support frame 1 and the second support frame 3 through movement is achieved.

[0078] When this support assembly is applied to a cooling fan, the wet curtain can be fixedly installed on the second support frame 3. Through the cooperation of the first connector 2 and the second connector 4, the installation and removal between the first support frame 1 and the second support frame 3 can be realized. This allows users to easily remove the second support frame 3 from the first support frame 1 and clean the wet curtain, thereby reducing the risk of bacterial growth caused by residual dirt on the wet curtain.

[0079] Preferably, the first direction is clockwise and the second direction is counterclockwise;

[0080] Alternatively, the first direction is counterclockwise, and the second direction is clockwise.

[0081] Multiple first connectors 2 are distributed in a ring on the first support frame 1, and correspondingly, multiple second connectors 4 are also distributed in a ring on the second support frame 3. This structure allows the second support frame 3 to be installed, engaged, and disassembled with the first support frame 1 by rotating around its own axis. In this embodiment, the first direction and the second direction are opposite to each other. That is, if the first direction is assumed to be clockwise, then the second direction is counterclockwise; if the first direction is assumed to be counterclockwise, then the second direction is clockwise. Compared with the existing disassembly method of the wet curtain support assembly, the rotational disassembly method is not only convenient to operate, but also minimizes the space required for the second support frame 3 to move. This allows the second support frame 3 to complete the installation and disassembly with the first support frame 1 in a small space, saving the installation space of the support assembly. The assembly can then use the saved installation space to reduce its own size or add other components, thereby improving the performance of the assembly.

[0082] By distributing the first connector 2 and the second connector 4 in a ring along the first support frame 1 and the second support frame 3 respectively, the second support frame 3 can be installed and disassembled with the first support frame 1 in a narrow space by rotating around the axis, saving the installation space of the support components. Based on this, the appliance can use the saved installation space to reduce its own size or add other components, thereby improving the performance of the appliance.

[0083] Optionally, such as Figure 1-9 As shown, in one implementation of this embodiment,

[0084] The first connector 2 includes a first sub-connector 201 and a second sub-connector 202;

[0085] The second connector 4 includes a third sub-connector 401 and a fourth sub-connector 402;

[0086] The first sub-connector 201 engages with the third sub-connector 401, defining the circumferential and / or axial position of the second support frame 3 on the first support frame 1;

[0087] The second sub-connector 202 engages with the fourth sub-connector 402, defining the axial and / or circumferential positions of the second support frame 3 on the first support frame 1.

[0088] In this embodiment, multiple first connectors 2 and multiple second connectors 4 are provided;

[0089] The first connector 2 and the second connector 4 correspond one-to-one;

[0090] The second connector 4 engages with the corresponding first connector 2 to define the circumferential and axial positions of the second support frame 3 on the first support frame 1.

[0091] Furthermore, the plurality of first connectors 2 include a first sub-connector 201 and a second sub-connector 202;

[0092] The plurality of second connectors 4 include a third sub-connector 401 and a fourth sub-connector 402;

[0093] The first sub-connector 201 engages with the third sub-connector 401 to define the circumferential and / or axial position of the second support frame 3 on the first support frame 1.

[0094] The fourth sub-connector 402 engages with the fourth sub-connector 402 to define the axial and / or circumferential positions of the second support frame 3 on the first support frame 1.

[0095] In this embodiment, the plurality of first connectors 2 include a first sub-connector 201 and a second sub-connector 202, and the plurality of second connectors 4 include a third sub-connector 401 and a fourth sub-connector 402. The first sub-connector 201 and the third sub-connector 401 can cooperate with each other to form a connection. The connection between the two can limit the circumferential rotation of the second support frame 3 on the first support frame 1. That is, when the second support frame 3 rotates along the first direction on the first support frame 1 until the first sub-connector 201 and the third sub-connector 401 are connected, the second support frame 3 can no longer continue to rotate along the first direction. At this time, the second support frame 3 has been installed on the first support frame 1. The second sub-connector 202 and the fourth sub-connector 402 can cooperate to form a connection. The connection between the two can limit the axial movement of the second support frame 3 on the first support frame 1. That is, when the second support frame 3 is installed on the first support frame 1, the connection between the second sub-connector 202 and the fourth sub-connector 402 can restrict the second support frame 3 from moving along the axial direction of the first support frame 1, thereby improving the connection strength between the second support frame 3 and the first support frame 1.

[0096] Preferably, the connection between the first sub-connector 201 and the third sub-connector 401 can also limit the axial movement of the second support frame 3 on the first support frame 1. That is, when the second support frame 3 is installed on the first support frame 1, the second support frame 3 can no longer move along the axial direction of the first support frame 1. The second sub-connector 202 and the fourth sub-connector 402 can also limit the circumferential movement of the second support frame 3 on the first support frame 1. That is, when the second support frame 3 rotates along the first direction on the first support frame 1 until the second sub-connector 202 and the fourth sub-connector 402 are connected, the second support frame 3 can no longer continue to rotate along the first direction due to the connection and cooperation of the second sub-connector 202 and the fourth sub-connector 402.

[0097] By connecting the first sub-connector 201 with the third sub-connector 401 and the second sub-connector 202 with the fourth sub-connector 402, the axial and circumferential movements of the second support frame 3 on the first support frame 1 can be limited simultaneously, thereby improving the connection strength between the second support frame 3 and the first support frame 1.

[0098] Optionally, such as Figure 1-6 As shown, in one implementation of this embodiment,

[0099] One of the first sub-connector 201 and the third sub-connector 401 is configured as a first snap-fit ​​groove structure, and the other is configured as a snap-fit ​​block structure. The first snap-fit ​​groove structure has a first snap-fit ​​groove opening end 2011 and a first closed end 2012.

[0100] Wherein, the card block structure is inserted into the first card slot structure along the first card slot opening end 2011 and is limited in the first card slot structure by the first closed end 2012, and the second support frame 3 is installed on the first support frame 1.

[0101] The locking block structure disengages from the first locking slot structure along the first locking slot end 2011, and the second support frame 3 is detached from the first support frame 1.

[0102] In this embodiment, the first sub-connector 201 is a first snap-fit ​​groove structure, and the third sub-connector 401 is a snap-fit ​​block structure. The first snap-fit ​​groove structure has a first snap-fit ​​groove opening end 2011 and a first closed end 2012. Taking the distribution of multiple first sub-connectors 201 along a ring on the first support frame 1 as an example, by arranging the first snap-fit ​​groove opening end 2011 and the first closed end 2012 along the tangential direction of the ring line where the first sub-connector 201 is located, at least one of the first snap-fit ​​groove opening end 2011 and the first closed end 2012 is located on the tangent line of the ring line where the first sub-connector 201 is located, so that the first snap-fit ​​groove structure and the snap-fit ​​block structure of the third sub-connector 401 are connected in cooperation. In other words, when the second support frame 3 is installed on the first support frame 1, the third sub-connector 401 moves towards the first sub-connector 201 along the first direction. The locking block structure is inserted into the interior of the first locking groove structure from the first locking slot end 2011 along the tangential direction of the loop where the first sub-connector 201 is located, until the locking block structure abuts against the first closed end 2012. The first closed end 2012 blocks the locking block structure so that it can no longer continue to move along the circumference of the first support frame 1, thereby fixing the locking block structure in the first locking groove structure. At this time, the first sub-connector 201 and the third sub-connector 401 are connected, and the second support frame 3 is installed on the first support frame 1. When the second support frame 3 is removed from the first support frame 1, the third sub-connector 401 is first moved away from the first sub-connector 201 along the second direction. The locking block structure moves from the first closed end 2012 to the first locking slot end 2011 along the tangential direction of the loop where the first sub-connector 201 is located until the locking block structure is completely disengaged from the first locking slot structure. At this time, the first sub-connector 201 and the third sub-connector 401 are disconnected, and the second support frame 3 and the first support frame 1 are disassembled and separated.

[0103] Optionally, such as Figure 1-6 As shown, in one implementation of this embodiment,

[0104] The first support frame 1 is provided with a plurality of first sub-connectors 201 distributed along the circumference, and the second support frame 3 is provided with a plurality of third sub-connectors 401 distributed along the circumference, and the plurality of third sub-connectors 401 correspond one-to-one with the plurality of first sub-connectors 201.

[0105] The second support frame 3 is rotatably mounted to or detached from the first support frame 1;

[0106] Multiple first snap-fit ​​slot ends 2011 face the same rotation direction.

[0107] In this embodiment, there are multiple first snap-fit ​​slot structures, which are respectively arranged on the upper, left, and right sides of the first support frame 1 to form a triangular distribution, thereby achieving three-point positioning and locking of the second support frame 3. With the first direction being clockwise, the first snap-fit ​​slot structure located on the upper side of the first support frame 1 is a downwardly folded L-shaped buckle. This buckle has two first closed ends 2012, one of which is located above the first snap-fit ​​slot opening end 2011, and the other is located to the right of the first snap-fit ​​slot opening end 2011. The two first closed ends 2012 contact the upper and right end faces of the snap-fit ​​block structure, respectively, to restrict the corresponding second sub-connector 202 from moving radially and circumferentially along the first support frame 1. The movement creates a bidirectional limiting space within the buckle. A trapezoidal protrusion is provided circumferentially along the side of the buckle away from the first support frame 1 to limit the movement trajectory of the second sub-connector 202 during connection. The first snap-fit ​​groove structure on the left side of the first support frame 1 is a downwardly folded L-shaped buckle, with its first snap-fit ​​groove opening end 2011 located below the first closed end 2012. The first snap-fit ​​groove structure on the right side of the first support frame 1 is an upwardly folded L-shaped buckle, with its first snap-fit ​​groove opening end 2011 located above the first closed end 2012. To ensure the connection strength between the first snap-fit ​​groove structure and the snap-fit ​​block structure, the distance from the first closed end 2012 to the first snap-fit ​​groove opening end 2011 in the first snap-fit ​​groove structure is set to be no less than the height of the snap-fit ​​block structure, thus maximizing the contact area between the first snap-fit ​​groove structure and the snap-fit ​​block structure. The width of the first insertion port along the axial direction of the first support frame 1 is slightly less than the thickness of the second connector 4, allowing an interference fit to be formed between the first snap-fit ​​groove structure and the snap-fit ​​block structure.

[0108] By constructing the first sub-connector 201 and the third sub-connector 401 into a locking block structure and a groove structure, and by setting the first locking groove opening end 2011 and the first closing end 2012 on the first locking groove structure, it is possible to connect the second support frame 3 with the first support frame 1, and also to limit the range of circumferential movement of the second support frame 3, so as to prevent the second support frame 3 from missing the installation position due to excessive displacement, thereby further improving the installation efficiency of the second support frame 3 and the first support frame 1.

[0109] Optionally, such as Figure 6 As shown, in one implementation of this embodiment,

[0110] The third sub-connector 401 is provided with a connecting reinforcing rib 121 on the side near the second support frame 3;

[0111] And / or, structural reinforcing ribs 122 are formed on the sidewall of the third sub-connector 401.

[0112] In this embodiment, the connecting reinforcing rib 121 is provided at the connection between the third sub-connector 401 and the second support frame 3 to improve the connection strength between the third sub-connector 401 and the second support frame 3, making the connection between the third sub-connector 401 and the second support frame 3 less prone to breakage. The structural reinforcing rib 122 is formed on the third sub-connector 401 to improve the structural strength of the third sub-connector 401 itself, making the third sub-connector 401 less prone to breakage.

[0113] Preferably, the structural reinforcing ribs 122 are distributed in a cross shape on the third sub-connector 401.

[0114] By setting connecting reinforcing ribs and structural reinforcing ribs at the connection between the third sub-connector 401 and the second support frame 3, and on the third sub-connector 401, the structural strength of the third sub-connector 401 itself and at the connection with the second support frame 3 is improved, making the connection between the second support frame 3 and the first support frame 1 more firm and stable.

[0115] Optionally, in one implementation of this embodiment, such as Figure 1-3 As shown in Figure 5-8,

[0116] One of the second sub-connector 202 and the fourth sub-connector 402 is configured as a snap-fit ​​structure, and the other is configured as a second snap-fit ​​groove structure, the second snap-fit ​​groove structure having a second snap-fit ​​groove opening end 4021 and a second closed end 4022;

[0117] Wherein, the snap-fit ​​structure is snapped into the second snap-fit ​​groove structure along the second snap-fit ​​groove opening end 4021, the inner side of the snap-fit ​​structure is formed with a guide slope 2022, the guide slope 2022 abuts against at least one wall surface of the second snap-fit ​​groove structure, the snap-fit ​​structure is limited in the second snap-fit ​​groove structure by the second closed end 4022, and the second support frame 3 is installed on the first support frame 1;

[0118] The snap-fit ​​structure disengages from the second snap-fit ​​groove structure along the second snap-fit ​​groove end 4021, and the second support frame 3 is detached from the first support frame 1.

[0119] In this embodiment, taking the distribution of multiple first sub-connectors 201 and one second sub-connector 202 along a ring on the first support frame 1 as an example, a guide slope 2022 is formed on the inner surface of the side wall of the snap-fit ​​structure. The thickness of the guide slope 2022 gradually increases along the direction from the center of the ring where the second sub-connector 202 is located to the edge of the ring. That is, the closer the guide slope 2022 is to the center of the ring, the smaller its thickness, and the farther the guide slope 2022 is from the center of the ring, the larger its thickness.

[0120] The fourth sub-connector 402 is configured as a second snap-fit ​​groove structure, which is provided with a second snap-fit ​​groove opening end 4021 and a second closed end 4022. Since the second snap-fit ​​groove structure needs to cooperate with the snap-fit ​​tab structure, the snap-fit ​​tab structure needs to be arranged along the tangential direction of the loop where the fourth sub-connector 402 is located. At the same time, the second snap-fit ​​groove opening end 4021 and the second closed end 4022 are also arranged along the tangential direction of the loop where the fourth sub-connector 402 is located, so that at least one of the second snap-fit ​​groove opening end 4021 and the second closed end 4022 is located on the tangent of the loop where the first sub-connector 201 is located.

[0121] When the second support frame 3 is installed on the first support frame 1, the second sub-connector 202 moves towards the fourth sub-connector 402 along the first direction. The guide slope 2022 of the snap-fit ​​structure is inserted into the interior of the second snap-fit ​​groove structure from the second snap-fit ​​slot end 4021 along the tangential direction of the loop where the fourth sub-connector 402 is located, until the guide slope 2022 of the snap-fit ​​structure abuts against the second closed end 4022. The second closed end 4022 blocks the snap-fit ​​structure, preventing it from continuing to move along the circumference of the first support frame 1, thereby restricting the guide slope 2022 of the snap-fit ​​structure within the second snap-fit ​​groove structure. At this time, the guide slope 2022 of the snap-fit ​​structure forms an abutment fit with at least one side wall of the second snap-fit ​​groove structure, and the second sub-connector 202 and the fourth sub-connector 402 are connected. The second support frame 3 is then installed on the first support frame 1. When it is necessary to remove the second support frame 3 from the first support frame 1, the second sub-connector 202 is first moved away from the fourth sub-connector 402 along the second direction. The guide slope 2022 of the snap-fit ​​structure moves from the second closed end 4022 to the second snap-fit ​​slot end 4021 along the tangential direction of the loop where the fourth sub-connector 402 is located, until the guide slope 2022 of the snap-fit ​​structure is completely disengaged from the second snap-fit ​​slot structure. At this time, the second sub-connector 202 is disconnected from the fourth sub-connector 402, and the second support frame 3 is disassembled from the first support frame 1.

[0122] Preferably, the second snap-fit ​​groove structure is a U-shaped groove with two second snap-fit ​​groove openings 4021. The guide slope 2022 of the snap-fit ​​piece structure and the U-shaped groove are pressed against each other through an interference fit to form an anti-disengagement locking structure. The depth of the U-shaped groove is set to 1.2 to 1.5 times the thickness of the side wall of the snap-fit ​​piece structure, so that the U-shaped groove and the snap-fit ​​piece structure can always maintain a large compressive force. The inclination angle of the guide slope 2022 of the snap-fit ​​piece structure is between 40 and 50 degrees, which facilitates the U-shaped groove to rotate into position on the guide slope 2022 of the snap-fit ​​piece structure, making the connection between the second snap-fit ​​groove structure and the snap-fit ​​piece structure smoother.

[0123] By constructing the second sub-connector 202 and the fourth sub-connector 402 into a snap-fit ​​structure with a guide slope 2022 and a second snap-fit ​​groove structure with a second snap-fit ​​groove opening end and a second closed end 4022, the second support frame 3 is detachably connected to the first support frame 1, thereby limiting the axial and circumferential movement range of the second support frame 3. This not only prevents the second support frame 3 from missing its installation position due to excessive displacement, but also prevents the second support frame 3 from moving axially in the first support frame 1, further improving the connection strength between the second support frame 3 and the first support frame 1.

[0124] Optionally, in one implementation of this embodiment, such as Figure 7 , 8 As shown,

[0125] The guide slope 2022 is used to guide the snap-fit ​​structure to snap into the second snap-fit ​​groove structure along the second snap-fit ​​groove end 4021;

[0126] The depth of the second card slot structure is 1.2 to 1.5 times the height of the guide slope 2022;

[0127] And / or, the angle between the guide slope 2022 and the vertical plane is α, where 40°≤α≤50°.

[0128] In this embodiment, since the guide slope 2022 of the second snap-fit ​​groove structure and the snap-fit ​​tab structure are in abutting fit, the ratio of the depth of the second snap-fit ​​groove structure to the height of the guide slope 2022 needs to be limited to a certain range to achieve a better fixing effect. If the ratio of the depth of the second snap-fit ​​groove structure to the height of the guide slope 2022 is too large, it means that a large part of the groove of the second snap-fit ​​groove structure is not in contact with the guide slope 2022. In this case, the groove wall of the second snap-fit ​​groove structure forms a long lever arm, which will result in a smaller torque at the position abutting the guide slope 2022, thereby increasing the risk of the guide slope 2022 slipping out of the second snap-fit ​​groove structure. If the ratio of the depth of the second card slot structure to the height of the guide slope 2022 is too small, it means that a large part of the guide slope 2022 is not in contact with the second card slot structure. Insufficient contact area between the two will result in a smaller interaction force between them, which will also increase the risk of the guide slope 2022 slipping out of the second card slot structure.

[0129] Preferably, the depth of the second snap-fit ​​groove structure is set to h2, the height of the guide slope 2022 is set to h1, and 1.2≤h2 / h1≤1.5 is set. This ensures that the guide slope 2022 is in complete contact with the second snap-fit ​​groove structure, and also ensures that the interaction force between the guide slope 2022 and the second snap-fit ​​groove structure is large enough, thereby making the contact fit between the wall of the second snap-fit ​​groove structure and the guide slope 2022 more reliable.

[0130] By setting the depth of the second snap-fit ​​groove structure within the range of 1.2 to 1.5 times the height of the guide slope 2022, the abutment fit between the second snap-fit ​​groove structure and the guide slope 2022 can be made more reliable, thereby further improving the connection strength between the second support frame 3 and the first support frame 1.

[0131] The angle α between the guide slope 2022 and the vertical plane is 40°≤α≤50°. This angle is limited to facilitate the second snap-fit ​​groove structure to be screwed into the snap-fit ​​piece structure, and it is in abutting fit with the guide slope 2022.

[0132] Optionally, in one implementation of this embodiment, such as Figure 1-6 As shown,

[0133] The first support frame 1 includes an annular frame and a connecting rib 5, wherein the connecting rib 5 is located inside the annular frame and connected to the annular frame;

[0134] When there are multiple first connectors 2 and multiple second connectors 4:

[0135] Multiple first connectors 2 are disposed on the connecting rib 5 and distributed circumferentially;

[0136] Multiple second connectors 4 are distributed circumferentially on the second support frame 3.

[0137] Preferably, the second sub-connector 202 includes a connecting end 2021, which is connected to the first support frame 1;

[0138] The second sub-connector 202 and a plurality of the first sub-connectors 201 are distributed circumferentially on the first support frame 1;

[0139] The fourth sub-connector 402 and the plurality of the third sub-connectors 401 are distributed circumferentially on the second support frame 3.

[0140] In this embodiment, the first support frame 1 is constructed as a ring frame, and its curved outer contour improves the adaptability of the first support frame 1 to the installation space. Connecting ribs are formed within the ring frame, each rib having multiple connecting ends and connecting to the inner circumferential surface of the ring frame. Multiple first connecting members 2 are distributed circumferentially on the connecting ribs. Specifically, second sub-connecting members 202 and multiple first sub-connecting members 201 are distributed circumferentially on the first support frame 1. Corresponding to multiple second connecting members 4, fourth sub-connecting members 402 and multiple third sub-connecting members 401 are distributed circumferentially on the second support frame 3. In this embodiment, the connecting ribs can be approximately a cross-shaped rib structure, thereby supporting the ring frame in both vertical and horizontal directions to withstand the force exerted on the first support frame 1 by the second support frame 3. When multiple first connecting members 2 are distributed circumferentially on the connecting ribs, each first connecting member 2 is equidistant from the center of the ring frame, allowing each second connecting member 4 on the second support frame 3 to simultaneously connect or disconnect from the first connecting member 2 on the first support frame 1.

[0141] The combination of the ring frame and the connecting ribs not only provides installation space for multiple first connectors 2, but also improves the structural strength of the first support frame 1, enabling the first support frame 1 to withstand greater forces applied to it by the second support frame 3, thereby reducing the failure rate of the support assembly.

[0142] Optionally, in one implementation of this embodiment, such as Figure 1 , 2 As shown in Figure 10,

[0143] A partition 6 is provided between the first support frame 1 and the connecting rib 5. The partition 6 is constructed as a mesh partition to limit the water inlet pipe of the wet curtain.

[0144] In this embodiment, a partition 6 is also provided between the first support frame 1 and the connecting rib. This partition 6 is constructed as a mesh partition. When the support assembly is used for the evaporative cooling fan and the second support frame 3 is used to fix the evaporative cooling pad, a water supply pipe needs to be connected to the second support frame 3. Since the water supply pipe and the second support frame 3 need to be connected through an interference fit of different pipe diameters, the water supply pipe will shake radially under the impact of water flow. This shaking can cause the water supply pipe to interfere with other components inside the evaporative cooling fan. The mesh partition between the first support frame 1 and the connecting rib can support the water supply pipe, reducing the risk of the water supply pipe shaking under the impact of water flow. By providing a mesh partition between the first support frame 1 and the connecting rib to support the water supply pipe radially, the risk of the water supply pipe shaking under the impact of water flow is reduced, further reducing the failure rate of the support assembly.

[0145] Optionally, in one implementation of this embodiment, such as Figure 1-6 As shown,

[0146] At least two first connectors 2 are symmetrically arranged on the connecting rib 5 in the horizontal direction, and at least two first connectors 2 are symmetrically arranged on the connecting rib 5 in the vertical direction. The line connecting the first connectors 2 in the horizontal direction and the line connecting the first connectors 2 in the vertical direction intersect at the center of the connecting rib 5.

[0147] Each of the second connectors 4 corresponds to one of the first connectors 2.

[0148] In this embodiment, four first connectors 2 are used as an example. Two first connectors 2 are symmetrically arranged on the connecting rib 5 in the horizontal direction, and the other two first connectors 2 are symmetrically arranged on the connecting rib 5 in the vertical direction. The line connecting the first connectors 2 in the horizontal direction and the line connecting the first connectors 2 in the vertical direction intersect at the center of the connecting rib 5, so that the line connecting the four first connectors 2 forms an approximate "+" shape. The four first connectors 2 cooperate with the second connectors 4 in the up, down, left and right directions of the connecting rib 5, respectively. With fewer connectors, the second support frame 3 can be more firmly connected to the first support frame 1.

[0149] The shape of the connecting rib 5 can be an approximately "+" shaped rib structure, which not only matches the distribution of the first connecting member 2, but also supports the ring frame in both the vertical and horizontal directions to withstand the force exerted on the first support frame 1 by the second support frame 3.

[0150] Optionally, in one implementation of this embodiment, such as Figure 9 As shown,

[0151] The first connector 2 located in the horizontal direction is constructed as a snap-fit ​​groove structure formed by connecting two walls, and a guide protrusion 203 is formed on the inner side of the snap-fit ​​groove structure.

[0152] The second connector 4, corresponding to the first connector 2 located in the horizontal direction, is constructed as a locking structure;

[0153] Wherein, the card block structure is inserted into the inner side of the card slot structure along the guide protrusion 203 and is limited by the guide protrusion 203 to the inner side of the card slot structure, and the second support frame 3 is installed on the first support frame 1;

[0154] The locking block structure disengages from the inner side of the locking groove structure along the guide protrusion 203, and the second support frame 3 is detached from the first support frame 1.

[0155] In this embodiment, the guide protrusion 203 not only facilitates the insertion of the locking block structure into the L-shaped locking groove structure, but also limits the locking block structure within the L-shaped locking groove structure, thereby effectively ensuring a firm connection between the second connector 4 and the first connector 2. When it is necessary to unscrew the locking block structure from the L-shaped locking groove structure, the locking block structure can be gently pressed towards the connecting rib 5, and then the locking block structure can be unscrewed along the guide protrusion 203.

[0156] Example 2

[0157] like Figure 10 As shown, this embodiment provides a wet curtain, including:

[0158] wet curtain body 7;

[0159] As in the support assembly of Embodiment 1, the wet curtain body 7 is mounted on the second support frame 3;

[0160] The second support frame 3 is provided with a first water outlet 301 that is connected to the first water inlet of the wet curtain body 7, and a second water outlet 302 that is connected to the second water outlet of the wet curtain body 7.

[0161] In this embodiment, the evaporative cooling pad includes a cooling pad body 7 and a support assembly as described in Embodiment 1. The cooling pad body 7 is mounted on a second support frame 3 of the support assembly. A first water outlet 301 and a second water outlet 302 are provided on the second support frame 3. A first water inlet and a second water outlet are provided on the cooling pad body 7. The first water inlet is connected to the first water outlet 301, and the second water outlet is connected to the second water outlet 302. When the cooling pad is in operation, water flows from the first water outlet 301 into the first water inlet and then into the cooling pad body 7. At this time, the water flows downwards from above the cooling pad body 7 into the second water outlet, and then into the second water outlet 302, finally exiting the cooling pad from the second water outlet 302.

[0162] Preferably, the second card slot structure is located to the left of the second outlet 302 and is adjacent to the second outlet 302.

[0163] Since the wet curtain in this embodiment includes the support component in Embodiment 1, the wet curtain also has all the technical effects of the support component in Embodiment 1, which will not be elaborated here.

[0164] Example 3

[0165] like Figure 11 , 12 As shown, this embodiment provides a fan, including:

[0166] The wet curtain in Example 2;

[0167] The fan head 10, the fan body 11, and the base 13 are respectively disposed at the upper end and the lower end of the fan body 11.

[0168] The wet curtain is disposed inside the fan head 10;

[0169] The fan is equipped with a water tank and a water pump. The water outlet of the water tank is connected to one end of the water inlet pipe 8, and the other end of the water inlet pipe 8 is connected to the first water outlet 301. The water inlet of the water tank is connected to one end of the water outlet pipe 9, and the other end of the water outlet pipe 9 is connected to the second water outlet 302. The water pump is used to pump the water in the water tank into the water inlet pipe 8.

[0170] In this embodiment, the fan includes the evaporative cooling pad, fan head 10, fan body 11, and base 13 as in Embodiment 2. The fan head 10 is located at the upper end of the fan body 11, and grilles are respectively provided on both sides of the fan head 10 along the axial direction. The base 13 is located at the lower end of the fan body 11. The evaporative cooling pad is located inside the fan head 10 and is used to cooperate with the fan head 10 to blow out cool air. A water tank and a water pump are provided inside the fan for supplying water to the evaporative cooling pad. The water tank and water pump can be located in the base 13 or in the fan body 11. The water outlet of the water tank is connected to one end of the water inlet pipe 8, and the other end of the water inlet pipe 8 is connected to the first water outlet 301. The water inlet of the water tank is connected to one end of the water outlet pipe 9, and the other end of the water outlet pipe 9 is connected to the second water outlet 302. The water pump is used to pump water from the water tank into the water inlet pipe 8. When the fan and the wet curtain are running simultaneously, the water pump applies pressure to the water in the water tank. The water flows from the water tank into the inlet pipe 8 and from the first outlet 301 to the wet curtain body 7. At this time, the water flows down from above the wet curtain body 7 into the second outlet and from the second outlet into the second outlet 302. Then it flows out of the wet curtain from the second outlet 302. After the water flows out of the wet curtain, it flows back to the water tank through the drainage system, thus realizing the circulation of the water inside the fan.

[0171] Since this embodiment includes the wet curtain in embodiment two, the fan in this embodiment also has all the technical effects of the wet curtain in embodiment two, which will not be elaborated here.

[0172] In summary, the ingenious design of the supporting components lies in:

[0173] First, when the support assembly is applied to a cooling fan, the wet curtain can be fixedly installed on the second support frame. Through the cooperation of the first connector and the second connector, the installation and removal between the first support frame and the second support frame can be realized. This allows users to easily remove the second support frame from the first support frame and clean the wet curtain, thereby reducing the risk of bacterial growth caused by residual dirt on the wet curtain.

[0174] Secondly, by constructing the first sub-connector and the third sub-connector into a combination of a locking block structure and a groove structure, and by setting a first locking groove opening end and a first closed end on the first locking groove structure, it is possible to connect the second support frame with the first support frame, and also to limit the range of circumferential movement of the second support frame, so as to prevent the second support frame from missing the installation position due to excessive displacement, thereby further improving the installation efficiency of the second support frame and the first support frame.

[0175] Third, by constructing the second and fourth sub-connectors as snap-fit ​​pieces with guide bevels and second snap-fit ​​grooves with a second snap-fit ​​opening and a second closed end, the second support frame is connected to the first support frame using an interference fit. This limits the axial and circumferential movement range of the second support frame simultaneously, preventing the second support frame from missing its installation position due to excessive displacement and preventing the second support frame from moving axially in the first support frame, thus further improving the connection strength between the second and first support frames.

[0176] Fourth, the combination of the ring frame and the connecting ribs not only provides installation space for multiple first connecting parts, but also improves the structural strength of the first support frame, enabling the first support frame to withstand greater forces applied to it by the second support frame, thereby reducing the failure rate of the support assembly.

[0177] Fifth, by setting a mesh partition between the first support frame and the connecting rib, the radial direction of the water supply pipe is supported, reducing the risk of the water supply pipe shaking under the impact of water flow, and further reducing the failure rate of the support component.

[0178] Sixth, by setting the depth of the second snap-fit ​​groove structure within the range of 1.2 to 1.5 times the height of the guide slope, the interference fit between the second snap-fit ​​groove structure and the guide slope can be made more reliable, thereby further improving the connection strength between the second support frame and the first support frame.

[0179] It can be further understood that in this disclosure, "many" refers to two or more, and other quantifiers are similar. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone.
