DETAILED DESCRIPTION

[0019] like Figures 1 to 6 As shown, a ventilated cross-type external heat dissipation LED street lamp includes a lamp housing 1, and multiple ventilation pipes 2 are horizontally inserted inside the lamp housing 1. The multiple ventilation pipes 2 are distributed circumferentially. The ventilation pipe 2 is a tubular structure with openings at both ends. In order to enhance the heat dissipation effect of the lamp housing 1, the number of circumferentially distributed ventilation pipes 2 can be increased at will. One end of the ventilation pipe 2 is located outside the lamp housing 1, and the other ends of the multiple ventilation pipes 2 are interconnected with a disc 3. The top of the disc 3 is coaxially connected to a connecting pipe 4. The top of the connecting pipe 4 extends to the outside of the lamp housing 1, and the top of the connecting pipe 4 is connected to a funnel-shaped liquid inlet. One end of the connecting pipe 4 extends to the outside of the lamp housing 1, and an exhaust component 5 is provided inside the connecting pipe 4.

[0020] The interior of the disc 3 is coaxially sealed and rotatably connected to the circular protrusion 6, and a first groove 601 is provided inside the circular protrusion 6. One end of the first groove 601 is connected to the connecting pipe 4, and the other end of the first groove 601 is connected to any ventilation pipe 2; the output end of the exhaust component 5 is connected to the transmission component 7, which is used to drive the circular protrusion 6 to rotate. The transmission component 7 includes an incomplete gear 704, which is connected to the exhaust component 5 through a speed change component. The bottom of the speed change component is coaxially provided with an incomplete gear 704, which is rotatably connected to the bottom end of the inside of the disc 3, and the outer side of the incomplete gear 704 is meshed with a transmission ring gear 705, which is fixed to the circular protrusion 6.

[0021] In this embodiment, when the lamp housing 1 is used for a long time, a lot of heat is generated inside the lamp housing 1, which can be discharged to the external environment through multiple ventilation pipes 2 made of heat exchange material. In order to reduce the chance of mosquitoes climbing and accumulating inside the ventilation pipes 2, the ventilation pipes 2 are all made of light-proof material. In order to further prevent mosquitoes from entering the ventilation duct 2 and accumulating therein, the exhaust assembly 5 can be activated to draw the external natural wind through the connecting pipe 4 into the first groove 601 and then discharged along the ventilation duct 2. This not only removes the heat inside the lamp housing 1, but also removes the mosquitoes accumulated inside the ventilation duct 2, thereby improving the heat dissipation effect. The exhaust assembly 5 is started, and the speed change assembly is used to reduce speed, thereby driving the incomplete gear 704 to rotate. The rotation of the incomplete gear 704 drives the transmission ring gear 705 meshing with it to rotate. Due to the difference in the number of teeth between the incomplete gear 704 and the transmission ring gear 705, the rotation of the incomplete gear 704 can drive the transmission ring gear 705 to rotate intermittently. The rotation of the transmission ring gear 705 causes the circular protrusion 6 to rotate synchronously, connecting the first groove 601 with any ventilation pipe 2. It is worth noting that the angle of each rotation of the circular protrusion 6 can move from the first ventilation pipe 2 to the pipe opening position of the second ventilation pipe 2, and then from the pipe opening position of the second ventilation pipe 2 to the pipe opening position of the third ventilation pipe 2, and so on. like Figure 6 As shown, as a further solution of the present invention, the speed change assembly includes a rotating shaft 701, which passes through the circular protrusion 6 and is rotatably connected thereto, and a first gear 702 is fixedly connected to the outer side of the rotating shaft 701, and a second gear 703 is meshedly connected to one side of the first gear 702, and the second gear 703 and the incomplete gear 704 are coaxially arranged, and the second gear 703 is arranged on the top of the incomplete gear 704.

[0022] In this embodiment, the exhaust component 5 is started to drive the rotating shaft 701 to rotate, and the rotation of the rotating shaft 701 drives the first gear 702 to rotate synchronously. The rotation of the first gear 702 drives the second gear 703 engaged with it to rotate. Due to the difference in the number of teeth between the first gear 702 and the second gear 703, the rotation speed of the second gear 703 is less than the rotation speed of the first gear 702. It is worth noting that the second gear 703 and the incomplete gear 704 are coaxially arranged. Therefore, the rotation speed of the incomplete gear 704 is the same as that of the second gear 703. By setting the second gear 703 and the first gear 702, the rotation speed of the circular protrusion 6 is reduced, the connection time between the first groove 601 and the ventilation pipe 2 is increased, the ventilation time of any ventilation pipe 2 is increased, and the effect of cleaning mosquitoes and the heat dissipation effect are improved.

[0023] like Figure 7 As shown, as a further solution of the present invention, a second groove 602 is opened on the outer wall of the circular protrusion 6, and the second groove 602 is connected to the first groove 601. The cross-sectional shape of the second groove 602 is set to be arc-shaped; the cross-sectional shape of the first groove 601 is set to be L-shaped.

[0024] In this embodiment, the arc length of the second groove 602 is equal to the distance between two adjacent ventilation pipes 2. Whenever the exhaust component 5 starts to draw natural wind from the outside and exhaust it into any ventilation pipe 2, the circular protrusion 6 rotates under the drive of the transmission component 7. During the rotation of the circular protrusion 6, it is worth noting that, in the process of one end of the first groove 601 rotating from the pipe mouth position of any ventilation pipe 2 to the position of the ventilation pipe 2 adjacent to it, the end of the first groove 601 facing the ventilation pipe 2 is blocked by the inner wall of the disc 3. In order to ensure the smoothness of ventilation, the arc-shaped second groove 602 is used to allow the natural wind drawn from the outside to pass through the connecting pipe 4, the first groove 601, and the second groove 602 during this period and then connect with any ventilation pipe 2, so that the circular protrusion 6 maintains continuous ventilation operation during the rotation process, further improving the mosquito cleaning and heat dissipation effects.

[0025] like Figures 8 to 10 As shown, as a further solution of the present invention, a cross tube is provided between any two adjacent groups of ventilation tubes 2, and the cross tube is composed of a vertical tube 8 and a horizontal tube 9 that are interconnected; wherein, both ends of the horizontal tube 9 are opened, one opening is connected to the inside of the disc 3, and the other opening is connected to the spiral tube 14, both ends of the spiral tube 14 are opened, and one opening of the spiral tube 14 extends to the outside of the lamp housing 1; the two ends of the vertical tube 8 are sealed, and a slider 11 is installed in the vertical tube 8 to fit the inner wall thereof, and a through hole 1101 is opened inside the slider 11, and a thermal expansion member 10 and a spring 12 are respectively installed at both ends of the slider 11, and the thermal expansion member 10 and the spring 12 are respectively fixedly connected to the two ends inside the vertical tube 8.

[0026] In this embodiment, it is worth noting that the thermal expansion element 10 can be a thermal expansion strip or a thermal expansion airbag-like component. As for the thermal expansion coefficient or the expansion temperature range, the corresponding material can be selected by the user, and no further details will be given. When in use, in the initial state, the transverse tube 9 is blocked by the slider 11. When a lamp is used for a long time or in hot summer weather, the internal heat will not be dissipated in time. The temperature inside the lamp housing 1 will cause the thermal expansion member 10 to expand due to the heat, thereby pushing the slider 11 to move upward and compressing the spring 12. At this time, the through hole 1101 will form a conductive state with the transverse tube 9 during the upward movement of the slider 11. When the slider 11 moves up to the maximum stroke, the central axis of the through hole 1101 thereon overlaps with the central axis of the transverse tube 9. At this time, the heat inside the lamp housing 1 is dissipated through the spiral tube 14, thereby cooperating with the ventilation tube 2 to enhance the heat dissipation effect. The spiral tube 14 is a vertically spiral spiral coil. The spiral tube 14 is made of heat-dissipating material. During the rotation of the circular protrusion 6, the second groove 602 is connected to the horizontal tube 9, which can discharge part of the wind force through the horizontal tube 9 connected to the disc 3, thereby taking away the heat of the lamp in the vertical direction. Combined with multiple horizontally arranged ventilation pipes 2, cross-heating is performed to improve the heat dissipation effect.

[0027] like Figure 10 As shown, as a further solution of the present invention, a semiconductor cooling plate 13 is installed at the connecting position of the horizontal tube 9 and the spiral tube 14.

[0028] In this embodiment, the external wind extracted by the air extraction assembly 5 blows on the semiconductor cooling plate 13, and is cooled by the semiconductor cooling plate 13 before being discharged, thereby further improving the heat dissipation effect.

[0029] like Figure 4 As shown, as a further solution of the present invention, the exhaust assembly 5 includes a filter screen, which is installed inside the connecting pipe 4. A waterproof motor is installed at the bottom of the connecting pipe 4, and the output shaft of the waterproof motor is fixedly connected to the exhaust assembly 5.

[0030] In this embodiment, when rainy weather comes, rainwater can enter the interior of the disc 3 along the liquid inlet. The portion of the liquid whose level is higher than the pipe opening of the ventilation pipe 2 can be discharged along the ventilation pipe 2, taking away excess heat inside the lamp housing 1 and improving the heat dissipation effect. The portion of the liquid whose level is lower than the pipe opening of the ventilation pipe 2 can be temporarily retained inside the disc 3 and can be combined with air cooling to further improve the heat dissipation effect.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
