[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0024] like Figure 1-4 As shown, a heat dissipation junction box includes:

[0025] A bottom cover 1 is provided with an upper cover 2 on top thereof, and a wire plate 14 is provided between the upper cover 2 and the bottom cover 1;

[0026] A breathable plate 4 is slidably connected to the bottom cover 1, with its breathable opening facing the wire plate 14. A spring 43 connected to the bottom cover 1 is provided on one side of the breathable plate 4, and a semicircular arc groove 41 is provided on the other side;

[0027] The ventilation component 3 is arranged on the bottom cover 1. The ventilation component 3 includes a cleaning brush 38, a support sleeve 31 and a fan 33 arranged at the axis of the support sleeve 31. A rotating shaft 36 is clamped at the axis of the fan 33. The rotating shaft 36 cooperates with the cleaning brush 38. The cleaning brush 38 slides in the semicircular slide groove 41.

[0028] Specifically, an upper cover 2 is provided on the top of the bottom cover 1, and a connecting column is provided on the upper cover 2 to cooperate with the card hole 15 of the bottom cover 1. A wire plate 14 is provided between the upper cover 2 and the bottom cover 1, and a round seat 142 is provided on the bottom cover 1 to support the wire plate 14. In order to raise the bottom plate and further allow the air flow to pass through the bottom side of the bottom plate to improve the heat dissipation effect, the air permeable plate 4 is slidably connected to the bottom cover 1. There is a gap at the sliding connection between the air permeable plate 4 and the bottom plate, and its air vent faces the wire plate 14. A spring 43 connected to the bottom cover 1 is provided on one side of the air permeable plate 4, and a semicircular arc slide groove 41 is provided on the other side thereof. One side of the air permeable plate 4 refers to Figure 2 The left side shown is the other side, which refers to its opposite end. The ventilation component 3 is arranged on the bottom cover 1. The ventilation component 3 includes a cleaning brush 38, a support sleeve 31 and a fan 33 arranged at the axis of the support sleeve 31. A rotating shaft 36 is clamped at the axis of the fan 33, and the rotating shaft 36 cooperates with the cleaning brush 38. The cleaning brush 38 is located in the semi-circular slide groove 41 and slides. The fan 33 drives the cleaning brush 38 through the rotating shaft 36 to continuously scrape the ventilation holes on the ventilation plate 4 to remove dust attached to the ventilation holes, thereby reducing dust accumulation and improving the heat dissipation effect of the junction box. At the same time, when the cleaning brush 38 continuously scrapes the ventilation plate 4, the inclined slider 37 will intermittently disengage from the semi-circular slide groove 41, and under the elastic action of the spring 43, the ventilation plate 4 is pushed closer to the fan 33 and shaken, so that the dust on the ventilation plate 4 is shaken off into the dust box 5, further improving the dust cleaning effect and improving the heat dissipation effect inside the junction box.

[0029] As an embodiment further provided by the present invention, an inclined slider 37 is provided at one end of the cleaning brush 38, and the inclined slider 37 forms a 60° angle with the bottom surface of the semi-circular arc groove 41. The angle is such that after the inclined slider 37 detaches from the semi-circular arc groove 41, the inclined slider 37 can slide into the semi-circular arc groove 41 again through the inclined plate of the angle.

[0030] As an embodiment further provided by the present invention, the ventilation component 3 also includes a four-corner bracket 35 fixed in the support sleeve 31, and a rotating sleeve 34 that cooperates with the fan 33 is provided at the axis center of the four-corner bracket 35. The four-corner bracket 35 supports the fan 33 and the rotating sleeve 34 supports the fan 33, and the corners of the four-corner bracket 35 are all chamfered at 30° to reduce dust adhesion to the four-corner bracket 35 when the fan 33 is running, and further reduce the airflow blocked by the fan 33 to improve the heat dissipation effect of the junction box.

[0031] As an embodiment further provided by the present invention, a top plate 42 is symmetrically arranged on the breathable plate 4, and cylindrical grooves 421 that cooperate with the spring 43 are arranged in a linear array on the top plate 42. The cylindrical grooves 421 improve the connection effect between the top plate 42 and the bottom cover 1, and improve the elastic force of the spring 43 to push the breathable plate 4.

[0032] As a further embodiment provided by the present invention, a dust box 5 is slidably provided on the bottom cover 1, and the dust box 5 is located directly below the air permeable plate 4. A first inclined plate 51 and a second inclined plate 52 are sequentially provided in the dust box 5, and the first inclined plate 51 is located below the second inclined plate 52. Figure 4 As shown, this arrangement is to reduce the dust from entering the dust box 5 and then escaping from the dust box 5 and re-entering between the fan 33 and the air permeable plate 4, and further to prevent the airflow guided by the fan 33 from blowing away the dust in the dust box 5.

[0033] As an embodiment further provided by the present invention, the wire plate 14 includes a wire pressing end 141, and wire holes are symmetrically opened on the air-permeable plate 4. The fan 33 is electrically connected to the wire pressing end 141 through the wire holes, and the rotation of the fan 33 is controlled by receiving current and electrical signals through the wire plate 14.

[0034] As an embodiment further provided by the present invention, the bottom cover 1 is provided with a wire inlet hole 12 and a wire outlet hole 11, and the wire inlet hole 12 and the wire outlet hole 11 are both provided with a wire clamp 13, and the interior of the wire clamp 13 is provided with a clamping strip 131 in a circular array. The wire clamp 13 is threadedly connected to the bottom cover 1, and one of the wire clamps 13 is threadedly connected to the upper cover 2, and the clamping strip 131 inside the wire clamp 13 limits the swing angle of the wires and signal lines, reducing the wires from being dragged and detached from the wire board 14.

[0035] As a further embodiment provided by the present invention, one side of the support sleeve 31 is clamped with a guide tube 32 facing the fan 33. The guide tube 32 is conical and fixed to the support sleeve 31 by a screw, so that the airflow is transported directly to the fan 33.

[0036] The fan 33 rotates to draw air from the outside through the air plate 4 and into the bottom cover 1 to dissipate heat for the air plate 14 and the wires. After a long period of use, dust or debris will appear. When the fan 33 is running, the shaft 36 will be linked to make the cleaning brush 38 at the end of the shaft 36 rotate and continuously scrape the air opening on the air plate 4, so that the dust on the air opening falls into the dust box 5 for storage. Since the slide of the semi-circular slide groove 41 is a semi-circular slide groove, the inclined slider 37 at the end of the cleaning brush 38 will intermittently disengage from the semi-circular slide groove 41. At the same time, the air plate 4 is intermittently shaken under the pushing action of the spring 43, and the dust is shaken off into the dust box 5, further improving the cleaning effect of the dust. After a period of time, the dust box 5 can be pulled to clean the dust inside it, thereby improving the ventilation effect of the junction box.

[0037] The technical solution of the above-mentioned utility model provides a solution that is significantly different from the existing technology to address the technical problem that the existing technology solution is too single. The parts not involved in the technical solution of this application are the same as the existing technology or can be implemented by using the existing technology, and will not be repeated here.

[0038] The technical solutions in the above embodiments have clearly and completely described the contents of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
