[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a reactive power compensation device box for an electric vehicle charging pile, including a box body 1. A box door 2 is provided on the front of the box body 1. A dial indicator 3 and an indicator light 4 are provided on the box door 2. A reactive power compensation device required for charging the electric vehicle is provided inside the box body 1. A mounting bracket 5 connected to the electric vehicle charging pile is provided on the back of the box body 1. An exhaust component 8 is provided on one side of the box body 1. The exhaust component 8 is used to discharge the hot air inside the box body 1. An intake component 6 is provided on the other side of the box body 1. The intake component 6 is used to supplement air into the box body 1. An adsorption component 7 is provided inside the intake component 6. The intake component 6 includes an intake pipe 601 and an intake hood 602. The intake pipe 601 penetrates through the box body 1. The intake hood 602 is located below the intake pipe 601, and the bottom of the intake hood 602 is designed with an opening. The intake hood 602 is used to place the adsorption component 7. A side port 603 is opened on the side of the intake hood 602;

[0025] In the present invention, the intake hood 602 and the intake pipe 601 are provided. The intake pipe 601 is arranged in a bent manner so that its opening faces downward, which can prevent dust or rain from falling into the intake pipe 601. The intake hood 602 can place the adsorption component 7 to achieve the purpose of cleaning the air entering the box body 1 by using the adsorption component 7 and prevent dust from entering the box body 1.

[0026] An elastic sheet 604 is provided inside the intake hood 602. The elastic sheet 604 is used to squeeze and clamp the adsorption component 7;

[0027] By setting the elastic sheet 604, the elastic sheet 604 can deform to a certain extent depending on its own material and can automatically rebound and reset. In this way, the adsorption component 7 can be squeezed and clamped inside the intake hood 602, achieving the effect of quickly installing the adsorption component 7 and facilitating subsequent replacement and cleaning work.

[0028] The adsorption component 7 includes a dust adsorption cover 701 and a water vapor adsorption cover 702. The dust adsorption cover 701 is located on the outside, and the water vapor adsorption cover 702 is located on the inside.

[0029] By providing the water vapor adsorption cover 702 and the dust adsorption cover 701, the dust adsorption cover 701 can block and adsorb dust and larger impurities in the flowing air, preventing dust from entering the box body 1 and affecting the normal operation of the reactive power compensation device. The water vapor adsorption cover 702 can adsorb excessive moisture in the flowing air, avoiding the risk of water vapor condensation in the box body 1 and affecting the safety of the circuit.

[0030] A water diversion line 703 is provided at the bottom of the water vapor adsorption cover 702, and the water diversion line 703 is used to guide the accumulated water in the water vapor adsorption cover 702 to drain out.

[0031] By providing the water diversion line 703, after the water vapor adsorption cover 702 adsorbs a large amount of water vapor, the water vapor will condense into water droplets and flow out of the filtering component along the water diversion line 703 under the action of gravity.

[0032] The exhaust component 8 includes an exhaust duct 801 and a fan 802. The exhaust duct 801 penetrates through the box body 1. The fan 802 is arranged in the exhaust duct 801. An activity baffle 803 is provided at the position of the output end of the fan 802 in the exhaust duct 801. The side of the activity baffle 803 close to the top is rotatably connected to the exhaust duct 801.

[0033] By providing the activity baffle 803, the activity baffle 803 can rotate by means of being rotatably connected to the exhaust duct 801. When the fan 802 works, the air flow pushes the activity baffle 803 to open, and the hot air flow flows out of the box body 1. When the fan 802 is turned off, the activity baffle 803 loses the thrust of the air flow and rotates downward to reset under its own gravity and closes through the exhaust duct 801, preventing dust from entering the box body 1 through the exhaust duct 801. And the activity baffle 803 can only expand outward and cannot rotate inward.

[0034] A rain shield 804 is provided at the outer end of the exhaust duct 801, and the opening of the rain shield 804 is inclined downward.

[0035] By providing the rain shield 804, the rain shield 804 can set the outlet of the exhaust duct 801 obliquely downward, preventing rainwater from splashing into the exhaust duct 801. And the rain shield 804 is detachably connected to the exhaust duct 801, so that the rain shield 804 can be removed when maintaining the fan 802 or the activity baffle 803, avoiding the risk of accidentally touching the circuit when maintaining the fan 802 in the box body 1.

[0036] Working principle:

[0037] The fan 802 discharges the hot air inside the box body 1 through the exhaust duct 801. The airflow pushes open the movable baffle 803 and exhausts the air to the outside through the rain shield 804. After the hot air inside the box body 1 is discharged, negative pressure is generated inside it. The box body 1 uses the negative pressure to draw in the outside air through the air inlet hood 602 and the air inlet pipe 601. When the airflow enters the air inlet hood 602, it flows through the dust adsorption hood 701 and the water vapor adsorption hood 702, and both adsorb the dust and excessive water vapor in the air, so that the clean air flows into the box body 1.

[0038] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
