As described in the background art, in the prior art, the cabinet has a problem that both the waterproof property and the ventilation property cannot be achieved.

In order to solve the above-mentioned problems, an embodiment of the present application provides a waterproof ventilation assembly, referring to fig. 2 to 7, which includes a fixing frame 2 and a louver frame 3. The fixed frame 2 includes a first opening 21 and a second opening 22 disposed opposite to each other. The louver frame 3 is mounted in the fixed frame 2, and in a direction perpendicular to the louver frame 3, a projection of the louver frame 3 covers an area enclosed by the fixed frame 2. The louver 3 includes a plurality of blades 31 disposed in parallel and spaced apart relation, each blade 31 including a first blade 311 facing the first opening 21 and a second blade 312 facing the second opening 22. One end of the first sheet 311 is connected to one end of the second sheet 312, the first sheet 311 is gradually inclined downward from the second opening 22 toward the first opening 21, and the second sheet 312 is gradually inclined downward from the first opening 21 toward the second opening 22. The end of the first sheet 311 away from the second sheet 312 and the end of the second sheet 312 away from the first sheet 311 are respectively provided with a guide plate 313 extending downward. Wherein, the below of tripe frame 3 is provided with drainage structures 5, and drainage structures 5 are used for flourishing to connect and derive the liquid that falls from tripe frame 3.

In this application embodiment, can install waterproof ventilation subassembly on the cabinet body 1 of rack, when the rack meed circumstances such as rainfall or afforestation spraying, because the projection of tripe frame 3 covers the region that fixed frame 2 enclosed, the blade 31 of tripe frame 3 can't be crossed to the liquid directly gets into in the rack. When the liquid falls on the surface of the first sheet 311, the first sheet 311 may reduce the horizontal velocity of the liquid thereon so that the portion of the liquid flows downward along the surface of the blade 31; when part of the liquid does not fall on the first sheet 311 and directly passes over the first sheet 311 of the two adjacent blades 31, the bottom surface of the second sheet 312 of the upper blade 31 can also play a role in blocking the part of the liquid, so that the part of the liquid flows downwards along the second sheet 312 of the upper blade 31; in addition, when the water flow rate on the blade 31 is large, the liquid forms a liquid film on the blade 31, and according to the coanda effect and the viscosity of the liquid, the liquid flowing on the guide plate 313 can drag the liquid flowing on the first sheet 311 and the second sheet 312, so that the horizontal speed of the liquid on the first sheet 311 is further reduced, and the liquid can flow downwards through the blade 31. The water-blocking effect of the waterproof and ventilating assembly is ensured by discharging the liquid falling from the vane 31 through the water discharging structure 5. When the air flows through the waterproof ventilation assembly, the air cannot be detoured and turned back for many times, so that the air resistance of the air is small, and the ventilation performance of the cabinet is guaranteed. Thus, the waterproof ventilation assembly can effectively prevent water from entering the cabinet and ensure the ventilation performance of the cabinet.

The cross section of the fixing frame 2 is rectangular, and the fixing frame can be installed on a cabinet door 11 of the cabinet body 1. Illustratively, the shutter frame 3 further includes a frame 32, the frame 32 being mounted in the fixed frame 2, and the plurality of blades 31 being mounted in the frame 32.

For example, the sheet material may be folded to form the first sheet 311 and the second sheet 312 of the blade 31, or the first sheet 311 and the second sheet 312 may be connected to each other to form the blade 31, which is not limited only herein. It can be appreciated that the connection between the first sheet 311 and the second sheet 312 protrudes upward, when the air flows through the channel formed by the two adjacent blades 31, the air does not need to be repeatedly turned around and turned at a large angle, the wind resistance of the air flow in the channel is small, and the ventilation performance of the waterproof ventilation assembly is ensured. When the liquid flows on the first sheet 311 towards the inside of the cabinet body 1, the first sheet 311 increases the liquid flowing path, the horizontal speed of the liquid on the first sheet 311 gradually decreases under the gravity action of the liquid, most of the liquid can flow downwards on the first sheet 311, and a small part of the liquid can flow downwards on the second sheet 312 after flowing through the first sheet 311.

The guide plate 313 may be provided at the end of the first sheet 311 and the end of the second sheet 312, respectively, by bending, or the guide plate 313 may be connected to the end of the first sheet 311 and the end of the second sheet 312, respectively. The guide plate 313 may be a straight plate extending downward or a curved plate tangential to the sheet body, which is not limited herein. It should be noted that the guide plate 313 can change the falling direction of the liquid from the blade 31, so that the liquid can be discharged from the drainage structure 5 after falling from the blade 31, and the liquid is prevented from entering the cabinet.

As shown in fig. 4-6, the drainage structure 5 is provided with an inclined slope, and when the liquid falling on the blade 31 falls on the inclined slope, the liquid can directly flow out of the cabinet. Optionally, the drainage structure 5 further includes a water blocking portion 51 disposed at an end of the inclined surface facing the interior of the cabinet 1, and the water blocking portion 51 blocks the liquid on the inclined surface from entering the interior of the cabinet. Further, as shown in fig. 5 and 6, the top end of the water blocking portion 51 is provided with a water blocking section 511 extending downward toward the outside of the cabinet 1 to ensure the blocking effect of the water blocking portion 51 on the liquid. The drainage structure 5 may be provided at the bottom edge of the fixed frame 2, or the drainage structure 5 may be provided separately below the louver frame 3, which is not limited only.

It should be noted that, when the waterproof ventilation assembly is installed on the cabinet, the interior of the cabinet cannot be directly seen from the outside, and the liquid outside the cabinet cannot directly enter the cabinet beyond the blades 31 of the shutter frame 3. The specific number of the blades 31, the length of each blade 31 and the distance between the adjacent blades 31 can be set by those skilled in the art according to actual needs, so that the projection of the shutter frame 3 covers the area enclosed by the fixed frame 2, which is not limited only herein.

In an embodiment, referring to fig. 2, 7 and 8, as a specific implementation manner of the waterproof ventilation assembly provided in the embodiment of the present application, the first opening 21 faces the outside of the waterproof space, and the angle α between the second sheet 312 and the horizontal plane is greater than or equal to the angle β between the first sheet 311 and the horizontal plane.

It should be noted that, after the waterproof ventilation assembly is installed on the cabinet body 1 of the cabinet, the waterproof space is the space inside the cabinet body 1. The angle between each of the first sheet 311 and the second sheet 312 and the horizontal plane can be set by those skilled in the art according to actual needs, which is not limited herein. In this structure, when part of the liquid does not fall on the first sheet 311 and directly passes over the first sheet 311 of two adjacent blades 31, α is not smaller than β, so that the second sheet 312 of the upper blade 31 can stably block the part of the liquid, i.e. the waterproof performance of the cabinet is ensured.

In an embodiment, referring to fig. 9-12, as a specific implementation of the waterproof ventilation assembly provided in the embodiment of the present application, the blade 31 further includes a flow blocking section 317, one end of the flow blocking section 317 is connected to a position where the first sheet 311 and the second sheet 312 are connected, and the other end of the flow blocking section 317 extends upward.

Illustratively, the vanes 31 are formed in an approximately "lambda" type structure wherein the flow blocking sections 317 are sheet-like structures. In one possible implementation, the extending direction of the flow blocking section 317 is the same as the extending direction of the second sheet 312, and the flow blocking section 317 is integrally formed with the second sheet 312. The length of the flow blocking section 317 is not limited, and may be set by those skilled in the art according to actual needs.

In this structure, by providing the flow blocking section 317, when the water flow rate on the blade 31 is larger, the flow blocking section 317 can block the liquid flowing on the first sheet 311, so as to avoid more liquid flowing through the first sheet 311, so that the liquid flow rate on the second sheet 312 is smaller, and when the liquid falls from the second sheet 312, the liquid can fall on the drainage structure 5 to be discharged by the drainage structure 5. That is, the waterproof effect of the waterproof ventilation assembly can be further improved by the above arrangement.

In one embodiment, referring to fig. 10-14, as a specific implementation of the waterproof ventilation assembly provided in the embodiment of the present application, the bottom end of the deflector 313 is provided with a flow stopping segment 3131 extending toward the inside of the vane 31.

The flow stop segments 3131 are formed in a sheet-like structure, and each flow stop segment 3131 may extend in a horizontal direction, for example. The flow stop section 3131 may be disposed at the bottom end of the flow guide plate 313 by a bending process, or the flow stop section 3131 may be disposed at the bottom end of the flow guide plate 313 by an appropriate manner such as bonding or welding, which is not limited herein.

With this structure, when the liquid falls from the baffle 313, the liquid may flow in the extending direction of the flow stop section 3131, and finally falls from the end of the flow stop section 3131 away from the baffle 313, the liquid falling from the upper flow stop section 3131 of the upper blade 31 may fall on the first sheet 311 and the second sheet 312 of the lower blade 31, thereby forming turbulence on the first sheet 311 and the second sheet 312 of the lower blade 31. On the first sheet 311 of the lower blade 31, the turbulence loss of the water flow is increased, and the horizontal velocity of the water flow is reduced. That is, the waterproof effect of the waterproof ventilation assembly can be further improved by providing the flow stop section 3131.

In one embodiment, referring to fig. 2, 12 and 13, as a specific implementation of the waterproof ventilation assembly provided in the embodiment of the present application, the first opening 21 faces the outside of the waterproof space, the first sheet 311 includes a first guide section 3111 and a choke section 3112 located at one end of the first guide section 3111, and the second sheet 312 includes a transition section 3121 connected to one end of the choke section 3112 remote from the first guide section 3111 and a second guide section 3122 connected to one end of the transition section 3121 remote from the choke section 3112. The angle between the flow blocking section 3112 and the horizontal plane is greater than the angle between the first guide section 3111 and the horizontal plane, and the angle between the second guide section 3122 and the horizontal plane is greater than the angle between the transition section 3121 and the horizontal plane.

Illustratively, the first sheet 311 may be bent to form the first guide section 3111 and the choke section 3112, and the second sheet 312 may be bent to form the transition section 3121 and the second guide section 3122. The lengths of the first guide section 3111, the choke section 3112, the transition section 3121 and the second guide section 3122 may be set by those skilled in the art as required, and are not limited solely herein. Wherein, guide plates 313 are respectively provided at an end of the first guide section 3111 remote from the choke section 3112 and an end of the second guide section 3122 remote from the transition section 3121.

In this configuration, the first guide segment 3111 and the second guide segment 3122 may serve to drain and guide liquid thereon, respectively. When the liquid flows on the first sheet 311, the resistance of the flow blocking section 3112 to the liquid is greater than the resistance of the first guide section 3111 to the liquid, so that the flow blocking section 3112 can further reduce the horizontal velocity of the liquid on the first sheet 311, that is, the flow blocking section 3112 can play a role of blocking the liquid on the first sheet 311. In addition, when the gas passes through the adjacent two blades 31, since each blade 31 is provided with the transition section 3121, the gas is prevented from passing through a large-angle turn, and the ventilation of the waterproof ventilation assembly is ensured.

In one embodiment, referring to fig. 14, as a specific implementation of the waterproof ventilation assembly provided in the embodiment of the present application, a protrusion 314 is formed by protruding a middle portion of the first sheet 311 and a middle portion of the second sheet 312.

The middle portion of the first sheet 311 and the middle portion of the second sheet 312 may protrude upward to form the protrusion 314 or may protrude downward to form the protrusion 314, which is not limited herein. For example, the first sheet 311 and the second sheet 312 may be provided with a plurality of protrusions 314, respectively, and the plurality of protrusions 314 may be provided on the corresponding sheet at intervals along the length direction of the sheet.

In this structure, the protrusions 314 are disposed on the first sheet 311 and the second sheet 312, and when the liquid flows on the surface of the corresponding sheet, the protrusions 314 can increase the resistance of the liquid on the sheet, thereby reducing the horizontal velocity of the liquid on the sheet and improving the waterproof effect of the waterproof ventilation assembly.

In an embodiment, referring to fig. 15 and 16, as a specific implementation manner of the waterproof ventilation assembly provided in the embodiment of the present application, hole sites 315 are formed in the middle of the first sheet body 311 and the middle of the second sheet body 312.

Wherein, a plurality of hole sites 315 may be formed on the first sheet 311 and the second sheet 312, and the plurality of hole sites 315 are disposed on the corresponding sheet at intervals along the length direction of the sheet. In one possible implementation, the hole sites 315 may be formed on the first sheet 311 and the second sheet 312 by punching, and the vane 31 forms the flow blocking portions 316 below the first sheet 311 and below the second sheet 312, respectively, after punching. It can be appreciated that when the liquid flows on the lower surface of the first sheet 311 and the lower surface of the second sheet 312, the flow blocking portion 316 on the second sheet 312 can block the liquid, which is beneficial to improving the waterproof effect of the shutter frame 3.

With this structure, when the liquid flows on the surfaces of the first sheet 311 and the second sheet 312, part of the liquid falls from the hole 315 on the corresponding sheet, thereby increasing turbulence loss of the liquid, reducing the horizontal velocity of the liquid, and improving the waterproof effect of the waterproof ventilation assembly.

In one embodiment, referring to fig. 2 and 17-19, as a specific implementation of the waterproof ventilation assembly provided in the embodiments of the present application, the second opening 22 faces the inner side of the waterproof space. The waterproof ventilation assembly further comprises a water deflector mounted in the fixed frame 2, the water deflector being located on the side of the louver frame 3 facing the second opening 22. In the direction perpendicular to the louver 3, the projection of the water deflector covers the projection of the louver 3.

Illustratively, the water stop is positioned directly opposite the louver 3, and the area of the water stop is not smaller than the area of the louver 3. It should be noted that the water blocking member and the shutter frame 3 are both located above the water draining structure 5, that is, when the liquid falls from the water blocking member, the liquid can fall onto the water draining structure 5, and is drained out of the cabinet body 1 through the water draining structure 5. The water blocking member may be mounted in the fixed frame 2 by an appropriate manner such as bonding, snap connection, or fastening by a fastener, which is not limited herein.

This structure, when the rack is located the great environment of precipitation, if liquid falls the back from blade 31 and moves towards the inside direction of cabinet body 1, the water-retaining member can play the effect that blocks to this part liquid, guarantees waterproof ventilation assembly's water-proof effects.

In a specific embodiment, referring to fig. 17, as a specific implementation of the waterproof ventilation assembly provided in the embodiment of the present application, the water blocking member is a louver 41 installed in the fixed frame 2, and each louver 411 of the louver 41 is gradually inclined upwards from the first opening 21 toward the second opening 22. When the liquid moves towards the inside of the cabinet 1 after falling from the blades 31 of the louver frame 3, each louver 411 of the louver 41 can block part of the liquid, and the liquid can be discharged out of the cabinet through the drainage structure 5 after falling from the louver 41.

In another possible implementation, referring to fig. 18, the water blocking member is a baffle plate 42 installed in the fixed frame 2, and a plurality of ventilation holes are formed in the baffle plate 42. Illustratively, the area of the baffle 42 is not smaller than the area of the louver frame 3, and a plurality of ventilation holes may be arranged on the baffle 42 in a plurality of rows, and each ventilation hole may have a suitable shape such as a circle or a polygon. The baffle 42 is used for blocking the liquid falling from the blades 31, and ventilation holes are formed in the baffle 42 to ensure ventilation performance of the waterproof ventilation assembly.

Referring to fig. 19 and 20, in a further possible implementation, the water blocking member is a baffle 42 mounted in the fixed frame 2, and the projection of the second opening 22 exceeds the projection of the baffle 42 in a direction perpendicular to the louver 3. That is, a gap is provided between the shutter 42 and the second opening 22 of the fixed frame 2, for example, as shown in fig. 20, a gap is provided between both sides of the shutter 42 and the fixed frame 2, respectively.
