[0024] ​​​​Various specific embodiments of the present application will be described below with reference to the accompanying drawings, which are incorporated in, and constitute a part of this specification. It should be understood that the order of the steps in the methods described in this application is not meant to be limiting, and that the steps can be performed in any order unless otherwise specifically noted. For example, the term "first fixture" does not imply the existence of a "second fixture", and the term "second fixture" does not imply the existence of a "first fixture".

[0025] FIG. 1A is a perspective view of the flow uniformizer assembly 100 and the substrate 102 of the present application; FIG. 1B is a partially exploded view of the flow uniformizer assembly 100 and the substrate 102 of the present application, showing the detailed structure of the flow uniformizer assembly 100 and the substrate 102. As shown in FIG. 1A-FIG. 1B the flow uniformizer assembly 100 includes a flow uniformizer 104 and four mounting assemblies 106. The flow uniformizer 104 is mounted to the substrate 102 through the four mounting assemblies 106. Specifically, the substrate 102 is generally a flat plate. The substrate 102 is provided with a substrate through hole 112 and four substrate mounting holes 122. The substrate through hole 112 is generally square. The four substrate mounting holes 122 are arranged around the substrate through hole 112. The flow uniformizer 104 is also generally a flat plate and is generally square. The flow uniformizer 104 is provided with a flow uniformization area 103. The flow uniformization area 103 is provided with a plurality of flow uniformization holes 105. The flow uniformization holes 105 pass through the flow uniformizer 104. In the present application, the flow uniformization area 103 is generally square. The area of the flow uniformization area 103 is greater than the area of the substrate through hole 112. The plurality of flow uniformization holes 105 are arranged in a rectangular pattern in the flow uniformization area 103. Specifically, the plurality of flow uniformization holes 105 are arranged into eleven rows in the up-down direction and eleven columns in the front-back direction. The flow uniformizer 104 is also provided with four flow uniformizer through holes 124. The four flow uniformizer through holes 124 are arranged around the flow uniformization area 103 and correspond to the four substrate mounting holes 122. The four mounting assemblies 106 are generally rod-shaped and can pass through the corresponding substrate mounting holes 122 and flow uniformizer through holes 124, thereby mounting the flow uniformizer 104 to the substrate 102. When the flow uniformizer 104 is mounted in place on the substrate 102, the flow uniformizer 104 is arranged to the left of the substrate 102 and is arranged at a distance from the substrate 102. The flow uniformization area 103 is aligned with the substrate through hole 112, so that the airflow passing through the substrate through hole 112 can diffuse through the plurality of flow uniformization holes 105 on the flow uniformization area 103, so that the airflow passing through the substrate through hole 112 flows uniformly after passing through the flow uniformizer 104.

[0026] It should be noted that although the substrate through hole 112 and the flow uniformization area 103 are generally square in the present application, any shape of the substrate through hole 112 and the flow uniformization area 103 is within the scope of the present application.

[0027] FIG. 2 Is it like this? FIG. 1A The perspective view of the mounting assembly 106 shown illustrates its specific structure. (See figure.) FIG. 2 As shown, the mounting assembly 106 includes a flow equalizer connecting assembly 201, a support member 202, a fixing assembly 205, and a locking member 208. The support member 202 supports the flow equalizer 104. The flow equalizer connecting assembly 201 connects the support member 202 and the flow equalizer 104. The fixing assembly 205 is sleeved on the support member 202. The fixing assembly 205 is movable relative to the support member 202 and the flow equalizer 104, and connects the support member 202 to the base plate 102. The locking member 208 is sleeved on the support member 202 and is capable of unlocking and locking the support member 202.

[0028] like FIG. 2 As shown, the support member 202 is generally a rod. It extends along a first direction (e.g., left-right direction). The support member 202 can pass through... FIG. 1B The substrate mounting hole 122 and the flow equalization hood through hole 124 are shown in the diagram. Specifically, the support member 202 includes a support rod body 211 and an abutment portion 216. The support rod body 211 has a first end 212 and a second end 214 disposed opposite to each other. The first end 212 is provided with external threads, thereby connecting to the flow equalization hood connection assembly 201. The second end 214 is provided with the abutment portion 216. The size of the abutment portion 216 is larger than the size of the substrate mounting hole 122, so that when the support member 202 is inserted into the substrate mounting hole 122 on the substrate 102 from the right side, the abutment portion 216 can abut against the substrate 102 to prevent the support member 202 from continuing to move to the left relative to the substrate 102. In this application, the abutment portion 216 is generally hexagonal.

[0029] like FIG. 2As shown, the flow equalizer connecting assembly 201 includes a first nut 222, a first washer 224, a second washer 226, and a second nut 228. The first nut 222 and the second nut 228 are provided with hollow portions so as to be able to be fitted on the support rod body 211. The inner walls of the hollow portions are provided with internal threads so as to cooperate with the external threads on the first end portion 212. The first washer 224 and the second washer 226 are disposed on opposite sides of the flow equalizer 104, and the first nut 222 and the second nut 228 are disposed on opposite sides of the first washer 224 and the second washer 226, respectively. The first washer 224 and the second washer 226 are configured to provide a force away from each other for the first nut 222 and the second nut 228 when the first nut 222, the first washer 224, the second washer 226, the second nut 228, and the flow equalizer 104 are installed in place, so that the first nut 222 and the second nut 228 more tightly connect the flow equalizer 104 with the support rod body 211. As one example, the first washer 224 and the second washer 226 are springs.

[0030] As shown in FIG. 1, the support assembly 200 is movably connected to the base plate 102. As shown in FIG. 2, the support assembly 200 includes a support member 202 and a locking member 208. The support member 202 is movably connected to the base plate 102 by a fixing assembly 205. The locking member 208 is movably connected to the support member 202 by a connecting assembly 207. FIG. 2 As shown, the fixing assembly 205 is used to movably connect the support member 202 to the base plate 102. Specifically, the fixing assembly 205 includes a first fixing member 204 and a second fixing member 206. The first fixing member 204 and the second fixing member 206 are disposed on opposite sides of the base plate 102 and are connected to each other through the base plate mounting hole 122 (see FIG. 1). As one example, the first fixing member 204 and the second fixing member 206 are connected by threading. Specifically, the first fixing member 204 includes a first fixing member body 232 and a first connecting portion 234 connected to each other. The first connecting portion 234 is provided with external threads. The first fixing member 204 is provided with a first fixing member through hole 236. The first fixing member through hole 236 is disposed through the first fixing member body 232 and the first connecting portion 234, and is used to accommodate the support rod body 211. The second fixing member 206 is a nut, which has a hollow portion 242. The hollow portion 242 is used to accommodate the support rod body 211. The inner wall of the hollow portion 242 is provided with internal threads. The internal threads are able to cooperate with the external threads on the first connecting portion 234. FIG. 1B

[0031] FIG. 3 As shown in FIG. 2, the locking member 208 is movably connected to the support member 202 by a connecting assembly 207. As shown in FIG. 3, which is a perspective view of the locking member 208, the specific structure of the locking member 208 is shown. As shown in FIG. 4, which is a cross-sectional view of the locking member 208, the specific structure of the locking member 208 is shown. FIG. 2 FIG. 3 ​​As shown, the locking component 208 includes a locking component body 302 and a locking component connecting portion 306 connected to each other. The locking component connecting portion 306 has an external thread for engaging with an internal thread on the first fixing member 204, thereby connecting the locking component 208 to the fixing assembly 205. The locking component 208 has a locking component through hole 304. The locking component through hole 304 passes through the locking component body 302 and the locking component connecting portion 306, and is used to accommodate the support rod body 211. The locking component connecting portion 306 is configured such that when the locking component connecting portion 306 is connected to the fixing assembly 205, the locking component connecting portion 306 moves toward the locking component through hole 304 and abuts against the support rod body 211. Specifically, the locking component connecting portion 306 includes a connecting end and a free end. The connecting end faces to the left and is used to connect to the locking component body 302. The free end faces to the right and is used to connect to the fixing assembly 205. The locking component connecting portion 306 has four slots 308. Four slots 308 are evenly arranged circumferentially along the locking member connection portion 306. The slots 308 extend from the right surface of the free end of the locking member connection portion 306 toward the locking member body 302 (i.e., to the left). Thus, the free end of the locking member connection portion 306 has deformability, allowing it to move in a second direction toward or away from the locking member through-hole 304 (i.e., inward) or away from the locking member through-hole 304 (i.e., outward). The second direction is substantially perpendicular to the first direction. More specifically, the locking member 208 has a locked position and an unlocked position. The locking member 208 is configured such that: when the locking member 208 is in the locked position, it abuts against the support member 202 to prevent movement of the support member 202 relative to the fixing component 205, thereby locking the support member 202; and when the locking member 208 is in the unlocked position, it allows movement of the support member 202 relative to the fixing component 205 to unlock the support member 202.

[0032] FIG. 4A-FIG. 4C Is it like this? FIG. 1A The cross-sectional view shown is of the flow equalization shroud assembly 100 and the substrate 102 in the assembled state, wherein FIG. 4A-FIG. 4B The locking component 208 shown is in the unlocked position; FIG. 4C The locking component 208 shown is in the locked position. (As shown) FIG. 4A-FIG. 4CAs shown, when the flow hood assembly 100 and the base plate 102 are in the assembled state, the abutting portions 216 on the first end portion 212 and the second end portion 214 of the support member 202 are located on opposite sides of the base plate 102, respectively. The abutting portions 216 abut against the right side of the base plate 102, thereby impeding the movement of the support member 202 relative to the base plate 102 in the first direction to the left. The first fixing member 204 and the second fixing member 206 are located on the left and right sides of the base plate 102, respectively, and are sleeved on the support member 202. The external threads on the first fixing member 204 and the internal threads on the second fixing member 206 are matched, thereby connecting the first fixing member 204 and the second fixing member 206. As an example, the first connecting portion 234 on the first fixing member 204 passes through the base plate mounting hole 122 on the base plate 102, thereby connecting with the second fixing member 206. The first end portion 212 of the support member 202 is connected with the flow hood 104 through the flow hood connecting assembly 201. Specifically, the first nut 222 and the first gasket 224 are arranged on the left side of the flow hood 104, and the first nut 222 and the flow hood 104 are arranged on opposite sides of the first gasket 224. The second gasket 226 and the second nut 228 are arranged on the right side of the flow hood 104, and the flow hood 104 and the second nut 228 are arranged on opposite sides of the second gasket 226. The support member 202 is connected with the flow hood 104 through the matching of the internal threads on the first nut 222 and the external threads on the first end portion 212 and the matching of the internal threads on the second nut 228 and the external threads on the first end portion 212. The locking member 208 is sleeved on the support member 202 and is located between the flow hood connecting assembly 201 and the fixing assembly 205. When the flow hood assembly 100 and the base plate 102 are installed in place, as shown in FIG. 1A , the base plate through hole 112 is arranged in alignment with the flow area 103, thereby enabling the gas flowing out of the base plate through hole 112 to pass through the flow holes 105 on the flow area 103.

[0033] FIG. 4A-FIG. 4B As shown, the locking member 208 is in the unlocked position. As shown in FIG. 4A-FIG. 4B , when the locking member 208 is in the unlocked position, the locking member 208 unlocks the support member 202. The locking member 208 is sleeved on the support member 202, but is not connected with the fixing assembly 205. The locking member 208 allows the support member 202 to move relative to the base plate 102 in the first direction with the flow hood 104. Among them, FIG. 4A , the flow hood 104 is shown in the first position relative to the base plate 102, FIG. 4BThe flow equalizer 104 is shown in a second position relative to the substrate 102. When the flow equalizer 104 is in the first position, the flow equalizer 104 is disposed substantially parallel to the substrate 102 and has a first predetermined distance from the substrate 102. When the flow equalizer 104 is in the second position, the flow equalizer 104 is disposed substantially parallel to the substrate 102 and is as close to the substrate 102 as possible. The flow equalizer 104 has a second predetermined distance from the substrate 102. The first predetermined distance is greater than the second predetermined distance.

[0034] FIG. 4C The locking member 208 is shown in a locked position. As shown, when the locking member 208 is in the locked position, the locking member 208 abuts the support member 202 in the second direction, thereby impeding movement of the support member 202 relative to the substrate 102 in the first direction. As one example, the flow equalizer 104 is in the first position. The locking member 208 maintains the first predetermined distance between the flow equalizer 104 and the substrate 102. FIG. 4C

[0035] As shown, the locking member 208 is in the locked position or the unlocked position by connecting or disconnecting with the securing assembly 205. During connection of the locking member 208 with the securing assembly 205, the locking member 208 moves from the unlocked position to the locked position. Specifically, the locking member connecting portion 306 of the locking member 208 extends into the first securing member through-hole 236 of the first securing member body 232. The external threads on the locking member connecting portion 306 mate with the internal threads in the first securing member through-hole 236, thereby connecting the locking member connecting portion 306 with the first securing member 204. During the threaded connection, the first securing member body 232 exerts a force on the locking member connecting portion 306, thereby causing the free end of the locking member connecting portion 306 to move in the second direction toward the locking member through-hole 304 (i.e., inward). The free end of the locking member connecting portion 306 circumferentially embraces the support rod body 211 to abut the support rod body 211, thereby impeding movement of the support rod body 211 in the first direction. During disconnection of the locking member 208 from the securing assembly 205, the locking member 208 moves from the locked position to the unlocked position. Specifically, the locking member connecting portion 306 of the locking member 208 exits the first securing member through-hole 236 of the first securing member body 232. The external threads on the locking member connecting portion 306 disengage from the internal threads in the first securing member through-hole 236. The free end of the locking member connecting portion 306 is no longer subject to the force from the first securing member body 232, thereby moving in the second direction away from the locking member through-hole 304 (i.e., outward). The free end of the locking member connecting portion 306 disengages from the support rod body 211 to allow movement of the support rod body 211 relative to the substrate 102 in the first direction. FIG. 4A-FIG. 4C

[0036] FIG. 5A-FIG. 5B ​​is a sectional view of an air conditioner box according to an embodiment of the present application, wherein FIG. 5A The locking member 208 is shown in the locked position, and the flow straightener 104 is in the first position. FIG. 5B The locking member 208 is shown in the unlocked position, and the flow straightener 104 is in the second position. As an example, the air conditioner box is capable of adjusting the flow rate of the gas, and filtering impurities in the gas.

[0037] As shown in FIG. 5A-FIG. 5B The air conditioner box includes a box body 502. The box body 502 is generally cuboid, which defines a box cavity 504. The right end of the box body 502 has an inlet (not shown), and the left end of the box body 502 has an outlet (not shown). The inlet and the outlet communicate with the box cavity 504, so that the gas can enter the box cavity 504 from the inlet and flow out from the outlet. The air conditioner box also includes the above-mentioned substrate 102, the above-mentioned flow straightener assembly 100, a fan 506, and a filter 508. The specific structure of the substrate 102 and the flow straightener assembly 100 is described above, and will not be repeated here. The substrate 102 is fixedly arranged in the box cavity 504, and is connected with the box body 502, so as to divide the box cavity 504 into a first cavity 512 on the right side and a second cavity 514 on the left side. The first cavity 512 and the second cavity 514 communicate through the substrate through hole 112. The fan 506 is fixedly arranged in the first cavity 512 on the right side, and the outlet of the fan 506 faces the substrate through hole 112. The filter 508 is fixedly arranged in the second cavity 514 on the left side, and is connected with the box body 502. There is a mounting distance M between the right end of the filter 508 and the substrate 102. As an example, the mounting distance M is about 40 centimeters. The gas entering the box cavity 504 from the inlet is accelerated by the fan 506, and passes through the flow straightening area 103 arranged in alignment with the substrate through hole 112 after passing through the substrate through hole 112. The gas after flow straightening passes through the filter 508, and then is discharged from the air conditioner box via the outlet.

[0038] As shown in FIG. 5A When the air conditioner box is in normal use, the flow straightener 104 is set at the first position relative to the substrate 102, and the locking member 208 is in the locked position. That is, the flow straightener 104 has a first predetermined distance from the substrate 102. This can make the gas accelerated by the fan 506 flow through the flow straightener 104 after passing through the first predetermined distance, so as to achieve the flow straightening effect.

[0039] As shown in FIG. 5BAs shown, when the air handling unit is serviced, a service person needs to access between the filter 508 and the base plate 102. The flow straightener 104 is set at the second position relative to the base plate 102. That is, the flow straightener 104 has the second predetermined distance from the base plate 102. This can reduce the space occupied by the flow straightener assembly 100 between the filter 508 and the base plate 102, thereby allowing the service person to access between the filter 508 and the base plate 102 without dismounting the flow straightener 104 and the flow straightener assembly 100.

[0040] It is noted that although the locking member 208 is shown to include the locking member body 302 and the locking member connecting portion 306 connected together and the free end of the locking member connecting portion 306 is movable toward or away from the locking member through hole 304 in the second direction in the present application, at least a portion of the locking member 208 is movable toward or away from the locking member through hole 304 in the second direction in other embodiments.

[0041] It is noted that although the locking member connecting portion 306 is provided with four slots 308 in the present application, the locking member connecting portion 306 provided with at least two slots 308 is also within the protection scope of the present application.

[0042] The inventor of the present application finds that in the prior art, since the flow straightener is arranged between the filter and the base plate and since the flow straightener needs to have the first predetermined distance from the base plate, it is difficult for the service person to stand between the filter and the base plate to service the filter. The service person needs to dismount the flow straightener assembly from the base plate before servicing and mount the flow straightener assembly again after servicing. This increases the servicing time and the operation is complicated.

[0043] The flow straightener assembly 100 of the present application has the advantage that the flow straightener assembly 100 does not need to be dismounted from the base plate before servicing the air handling unit. Specifically, the locking member 208 of the present application can unlock the support member 202 to allow the flow straightener 104 and the support member 202 to move relative to the fixed assembly 205. When the air handling unit is in normal use, the flow straightener 104 keeps the first predetermined distance from the base plate 102 and the locking member 208 is in the locked position. When the air handling unit needs to be serviced, the service person unlocks the locking member 208 and pushes the flow straightener 104 and the support member 202 toward the base plate 102 so that the flow straightener 104 is close to the base plate 102 (for example, the flow straightener 104 is at the second position). When the servicing is completed, the service person moves the flow straightener 104 and the support member 202 away from the base plate 102 and keeps the flow straightener 104 at the first predetermined distance from the base plate 102. Then the locking member 208 is locked. Thus, during servicing, the flow straightener almost does not occupy the space between the filter and the base plate, thereby allowing the service person to stand between the filter and the base plate.

[0044] FIG. 6-FIG. 7The second embodiment of this application shows a locking member 608 and a first fixing member 604, wherein, FIG. 6 This is an assembly perspective view of the locking component 608 and the first fastener 604. FIG. 7 An exploded view of the locking component 608 and the first fastener 604. FIG. 1A-FIG. 5B The first fastener 204 and locking member 208 of the first embodiment shown are... FIG. 6-FIG. 7 The main difference between the first fixing member 604 and the locking member 608 in the second embodiment shown is that: FIG. 1A-FIG. 5B In the first embodiment shown, the locking member 208 is configured such that when the locking member 208 moves between a locked position and an unlocked position, the locking member 208 moves along a first direction, and at least a portion of the locking member 208 moves along a second direction; while FIG. 6-FIG. 7 In the second embodiment shown, the locking member 208 is configured to move in a second direction when the locking member 208 moves between a locked position and an unlocked position.

[0045] Specifically, such as FIG. 6-FIG. 7 As shown, the first fixing member 604 includes a first fixing member body 232 and a first connecting portion 234 connected together. The first connecting portion 234 has external threads. The first fixing member 604 has a first fixing member through hole 236. The first fixing member through hole 236 passes through the first fixing member body 232 and the first connecting portion 234 and is used to receive the support rod body 211. The first fixing member body 232 has a receiving hole 702. The receiving hole 702 is recessed inward from the outer surface of the first fixing member body 232. The receiving hole 702 communicates with the first fixing member through hole 236. The inner wall of the receiving hole 702 has internal threads. The locking member 608 is generally a nut. Specifically, the locking member 608 includes an operating portion 712 and a locking body 714 connected together. The operating portion 712 has a cross-shaped groove for engaging with a tool (e.g., a screwdriver). The locking body 714 has external threads, thereby engaging with the internal threads on the receiving hole 702. When the locking component 208 is in the locked position, the locking body 714 is inserted into the receiving hole 702. The locking body 714 has an external thread, which engages with the internal thread on the receiving hole 702. The free end of the locking body 714 abuts against the support component 202 to lock the support component 202. When the locking component 208 is in the unlocked position, the free end of the locking body 714 separates from the support component 202, thereby unlocking the support component 202.

[0046] It is noted that although the operation portion 712 is provided with a cross recess in the present application, the operation portion 712 can be in any form (e.g. a butterfly screw) in other embodiments, and the maintenance personnel can drive the locking body 714 to move in the second direction through the operation portion 712.

[0047] The locking member 608 of the second embodiment of the present application moves in the second direction to lock or unlock the first fixing member 604. This can reduce the setting length of the locking member 608 in the first direction, so that the flow cover 104 can be closer to the base plate 102 when the locking member 208 is in the unlocked position, thereby providing more space for the maintenance personnel.

[0048] It is noted that although the flow cover connecting assembly 201 including the first nut 222, the first gasket 224, the second gasket 226 and the second nut 228 is shown in the present application, any flow cover connecting assembly capable of connecting the flow cover 104 and the support member 202 is within the protection scope of the present application.

[0049] It is noted that although the fixing assembly is shown to include the first fixing member and the second fixing member in the present application, a fixing assembly including at least one fixing member is within the protection scope of the present application.

[0050] It is noted that although four mounting assemblies 106 are shown in the present application, a flow cover assembly including at least one mounting assembly 106 is within the protection scope of the present application.

[0051] Although the present disclosure has been described in connection with the embodiments outlined above, various alternatives, modifications, variations, improvements, and / or substantial equivalents, whether known or not, can be employed at any frequency and / or time thereafter. In addition, the technological effects and / or problems described in the specification are exemplary and not limiting; therefore, the disclosure disclosed in the specification can be used to solve other technical problems and have other technological effects and / or can solve other technical problems. Therefore, the examples of the embodiments of the present disclosure as stated above are intended to be illustrative rather than restrictive. Various changes can be made without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is intended to include all known or earlier developed alternatives, modifications, variations, improvements and / or substantially equivalent arrangements.
