AI Technical Summary
The dustproof mesh structure of existing photovoltaic grid-connected boxes is difficult to disassemble, leading to dust accumulation and blockage that cannot be effectively cleaned, thus affecting heat dissipation efficiency.
A quick-release dust filter structure was designed, including a rain cover, an air intake assembly, and a pluggable dust filter. The inclined electric cooling fan and the removable pluggable dust filter enable easy disassembly, assembly, and cleaning.
The dustproof netting can be easily disassembled and cleaned, ensuring the ventilation and heat dissipation efficiency of the photovoltaic grid-connected box and avoiding the problem of dust accumulation and blockage.

Abstract
Claims
1. A dust screen quick release structure, characterized by, include: The rain cover includes a first fixed cover and a second movable cover; the first fixed cover protrudes from the outside of the box, and the second movable cover is detachably connected to the side of the first fixed cover away from the box, and the first fixed cover and the second movable cover together form an external ventilation duct; An air intake assembly includes an air intake base and an electric cooling fan. The large end of the air intake base is fixed to the side of the housing, and the small end of the air intake base protrudes from the inner wall of the housing. The large end of the air intake base has a main air inlet, multiple sub-air inlets, and an inclined slot. The main air inlet is connected to the external ventilation duct and each of the sub-air inlets. The inclined slot is connected to the main air inlet through the multiple sub-air inlets. The electric cooling fan is inclinedly disposed on the back of the small end of the air intake base. The electric cooling fan is used to transport the air in the inclined slot to the interior of the housing. A pluggable dust filter is inserted into the inclined slot, and the pluggable dust filter is detachably connected to the inclined slot.
2. The dust screen quick release structure according to claim 1, wherein, The first fixed cover is welded to the outside of the box.
3. The dust screen quick release structure of claim 1, wherein, The second movable cover is engaged with the side of the first fixed cover opposite to the box body.
4. The dust screen quick release structure of claim 3, wherein, The first fixed cover has a first positioning hole, a buckle hole and a second positioning hole sequentially opened on the side of the second movable cover adjacent to the first fixed cover; The second movable cover has a first positioning protrusion, a snap-fit part, and a second positioning protrusion protruding sequentially on the side facing the first fixed cover; the first positioning protrusion snaps into the first positioning hole, the snap-fit part snaps into the buckle hole, and the second positioning protrusion snaps into the second positioning hole.
5. The dust screen quick release structure of claim 4, wherein, The top of the first fixed cover is provided with a clearance notch, which is connected to the buckle hole. The slot of the inclined slot is oriented towards the clearance notch, and the clearance notch is used to prevent the plug-in dust filter from being pulled out of the inclined slot.
6. The dust screen quick release structure of claim 4, wherein, The second movable cover has a handle protruding from the side opposite to the first fixed cover.
7. The dust screen quick release structure of claim 1, wherein, The plug-in dust filter has a handle at one end near the slot of the slanted slot.
8. The dust screen quick release structure of claim 1, wherein, The vertical cross-section of the air inlet is triangular.
9. A photovoltaic grid-tie box, characterized by, The photovoltaic grid-connected box includes the quick-release dustproof mesh structure according to any one of claims 1-8, and further includes a box body; the number of the rainproof cover, the air inlet component and the plug-in dustproof filter are all two, and the two rainproof covers, the two air inlet components and the two plug-in dustproof filters are respectively arranged on both sides of the box body.
10. The photovoltaic grid-tie box of claim 9, wherein, The photovoltaic grid-connected box also includes a protective top cover on the top of the box body, the protective top cover having a first heat dissipation channel and a second heat dissipation channel built in; both the first heat dissipation channel and the second heat dissipation channel are used to exhaust hot air from inside the box body; and / or, A wind deflector is installed on the bottom wall inside the housing, and the wind deflector is located between the two electric cooling fans.
