[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figures 1-5 The ventilation assembly 100 includes a front end plate 1 and a water baffle assembly 2. The front end plate 1 is provided with an air inlet a, which includes a first inlet a1. The first inlet a1 passes through the front end plate 1 along the first direction X. Along the first direction X, a front end plate 1 and a water-blocking assembly 2 are arranged sequentially, forming a first air inlet cavity Q1 with the water-blocking assembly 2 and the front end plate 1. The water-blocking assembly 2 includes a first baffle 21 and a second baffle 22. Along the first direction X, a first inlet a1 and the first baffle 21 are arranged opposite to each other. The second baffle 22 is located on the side of the first baffle 21 facing away from the first inlet a1. The first baffle 21 includes a first end 21a and a second end 21b arranged sequentially along the second direction Y. The first end 21a is inclined relative to the second end 21b in a direction opposite to the first direction X. The second baffle 22 includes a third end 22a and a fourth end 22b arranged sequentially along the second direction Y. The third end 22a is inclined relative to the fourth end 22b in a direction opposite to the first direction X. A connecting port b is provided between the second end 21b and the third end 22a. The connecting port b and the first inlet a1 are respectively connected to the first air inlet cavity Q1. Along the first direction X, the first baffle 21 blocks the first inlet a1. Wherein, the first direction X is perpendicular to the second direction Y.

[0026] The ventilation component 100 provided in this application embodiment can be applied to a cabinet 1000. The ventilation component 100 is disposed in the cabinet body 200 of the cabinet 1000. The front end plate 1 is disposed in the cabinet body 200. The connecting port b is connected to the receiving cavity Q3 inside the cabinet body 200. When the cabinet body 200 is placed in the use position, the second direction Y is the direction of gravity. When rainwater outside the cabinet 1000 enters the first air inlet cavity Q1 through the first inlet a1 along the first direction X with the airflow, the first baffle 21 blocks the rainwater. After the airflow passes over the first baffle 21 along the first end 21a to the second end 21b, the second baffle 22 plays a second blocking role on the airflow carrying rainwater. The first baffle 21 and the second baffle 22 cooperate to form a maze structure. The airflow carrying rainwater must pass over the first baffle 21 and the second baffle 22, and finally enter the receiving cavity Q3 inside the cabinet body 200 after passing through the connecting port b.

[0027] The ventilation component 100 provided in this application embodiment, when applied to the cabinet 1000, includes a water-blocking component 2. The water-blocking component 2 and the front end plate 1 enclose a first air inlet cavity Q1. The water-blocking component 2 includes a first baffle 21 and a second baffle 22. Along the first direction X, the first baffle 21 and the first inlet a1 are arranged opposite to each other. The second baffle 22 is located on the side of the first baffle 21 away from the first inlet a1. Both the first baffle 21 and the second baffle 22 are inclined towards the front end plate 1. The connecting port b between the first baffle 21 and the second baffle 22 is connected to the first air inlet cavity Q1. The airflow carrying rainwater must flow through the first inlet a1, the first air inlet cavity Q1 and the connecting port b in sequence before it can flow through the ventilation component 100 and enter the receiving cavity Q3 of the cabinet 200. The first baffle 21 and the second baffle 22 cooperate to form a maze structure, which can intercept rainwater and help reduce the problem of rainwater entering the receiving cavity Q3 and causing electronic equipment failure in rainy weather.

[0028] In some embodiments, the first baffle 21 is disposed parallel to the second baffle 22.

[0029] In some embodiments, the air inlet a includes a second inlet a2. Along the second direction Y, the first inlet a1 and the second inlet a2 are arranged in sequence. The water-blocking component 2 includes a third baffle 23. Along the second direction Y, the first baffle 21 and the third baffle 23 are arranged in sequence. The third baffle 23 includes a fifth end 23a and a sixth end 23b arranged in sequence along the first direction X. The sixth end 23b is inclined relative to the fifth end 23a in a direction opposite to the second direction Y. The second inlet a2 is connected to the first air inlet cavity Q1. Along the first direction X, the second inlet a2 and the fifth end 23a are arranged opposite to each other. The third baffle 23 blocks the second inlet a2. By setting a second inlet a2 and a third baffle 23, the second inlet a2 increases the air intake volume of the air inlet a, and the sixth end 23b of the third baffle 23 is inclined relative to the fifth end 23a in a direction opposite to the second direction Y. The third baffle 23 blocks the second inlet a2 along the first direction X. The third baffle 23 serves to block rainwater from entering the first air intake cavity Q1 through the second inlet a2. Under the action of gravity, the rainwater in the first air intake cavity Q1 can flow along the surface of the third baffle 23 to the fifth end 23a and finally be discharged from the second inlet a2, which helps to reduce the problem of water accumulation in the ventilation assembly 100.

[0030] In some embodiments, the third baffle 23 is arranged parallel to the third direction Z, wherein the first direction X, the second direction Y and the third direction Z are mutually perpendicular to each other.

[0031] In some embodiments, the surface of the third baffle 23 facing the first baffle 21 has an inclined surface 23c extending from the sixth end 23b to the fifth end 23a. The end edge of the inclined surface 23c in the direction from the sixth end 23b to the fifth end 23a and the farthest end of the second inlet a2 in the second direction Y are arranged sequentially along the second direction Y, so that when in use, the second direction Y is the direction of gravity, and the height of the end edge of the inclined surface 23c in the direction from the sixth end 23b to the fifth end 23a is higher than the lowest point of the second inlet a2 in the second direction Y, so that rainwater can be completely discharged to the second inlet a2 through the inclined surface 23c, which helps to further reduce the problem of water accumulation in the ventilation assembly 100.

[0032] It is understood that in other embodiments, in an air inlet a, more inlets can be provided between the first inlet a1 and the second inlet a2 along the second direction Y, such as a third inlet, a fourth inlet, etc., arranged along the second direction Y.

By setting the first waterproof cover 3 to cover the first inlet a1 and having a first opening c facing the second direction Y and communicating with the first inlet a1, ventilation requirements are met while reducing the amount of rainwater entering the ventilation assembly 100 through the first inlet a1.

[0045] In some embodiments, the ventilation assembly 100 includes a second waterproof cover 4, which is disposed on the side of the front end plate 1 facing away from the water-blocking assembly 2.

One end of the air duct box 8 is connected to the front panel 1, and the other end of the air duct box 8 is provided with a ventilation opening g. The ventilation opening g is arranged facing the first direction X and is used to communicate with the outlet 300a of the fan box 300. When applied to the cabinet 1000, the fan box 300 is used to accommodate the fan 301. When in working condition, the fan box 300 and the air duct box 8 are located in the receiving cavity Q3 of the cabinet 200. The fan 301 drives the airflow to flow sequentially through the air inlet a, the first air inlet cavity Q1, the receiving cavity Q3, the fan box 300, the air duct box 8, and the air outlet f.

[0056] In some embodiments, an elastic sealing ring 81 is provided around the periphery of the vent g. The elastic sealing ring 81 is used to abut against the fan box 300 along the first direction X to seal the end of the air duct box 8 with the vent g to the fan box 300.

[0057] In some embodiments, the duct box 8 is provided with a first duct h and a second duct i.

The end of the second duct i away from the first duct h extends in a second direction Y, and the air outlet f is connected to the end of the second duct i away from the first duct h, so that the air outlet f is offset from the first duct h. After rainwater enters the second duct i through the air outlet f, it needs to cross the second duct i in a direction opposite to the second direction Y before entering the first duct h, which helps to reduce the risk of rainwater entering the fan box 300 through the duct box 8.

[0058] In some embodiments, the air duct box 8 includes a first base plate 82, which is disposed on the side of the first air duct h facing the second direction Y.
