[0002] A ceiling lamp is a kind of lamp installed on the ceiling. Its design is simple and the installation is convenient. It can save space and does not affect the layout of indoor furniture. However, during the use of the ceiling lamp, more heat may be generated. If the heat dissipation effect of the lamp is not good, the internal temperature of the lamp may be too high after long-term use, affecting the service life of the lamp and even possibly causing potential safety hazards.

[0003] When designing traditional ceiling lamps, heat dissipation problems are usually considered. Therefore, they usually include some heat dissipation structures, such as heat dissipation holes or heat sinks. The function of these heat dissipation structures is to help dissipate the generated heat during the operation of the lamp and prevent the internal temperature of the lamp from being too high. The heat dissipation holes are usually located on the outside or bottom of the lamp, which can promote air circulation, while the heat sink is a specially designed heat dissipation element, and its structure helps to increase the surface area for heat dissipation.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: a heat dissipation structure for a ceiling lamp, including an outer housing 1, an upper surface of the outer housing 1 is fixedly connected with a mounting seat 2, a first filter screen 4 is fixedly connected inside the mounting seat 2, a fixing plate 7 is fixedly connected inside the outer housing 1, a sliding plate 5 is slidably connected inside the fixing plate 7, one end of the sliding plate 5 is fixedly connected with a filter plate 6, a driving component is arranged inside the fixing plate 7, a trapezoidal sliding plate 9 is slidably connected inside the fixing plate 7, an L-shaped sliding plate 10 is attached to the outer wall of the trapezoidal sliding plate 9, a clamping block 13 is fixedly connected to the outer wall of the L-shaped sliding plate 10, a telescopic rod 11 is fixedly connected to the outer wall of the clamping block 13, one end of the telescopic rod 11 is fixedly connected inside the fixing plate 7, a first spring 12 is sleeved on the outer wall of the telescopic rod 11, one end of the first spring 12 is fixedly connected inside the fixing plate 7, and the other end of the first spring 12 is fixedly connected to the outer wall of the clamping block 13. The outer wall of the clamping block 13 is slidably connected inside the sliding plate 5. A second filter screen 16 is fixedly connected inside the outer housing 1. The driving component includes a triangular push plate 8. The outer wall of the triangular push plate 8 is slidably connected inside the fixing plate 7. A second spring 23 is arranged inside the triangular push plate 8. One end of the second spring 23 is fixedly connected inside the fixing plate 7. The outer wall of the triangular push plate 8 is slidably connected inside the trapezoidal sliding plate 9;

[0025] Specifically, first, when the fan 14 starts to run, the external air is effectively introduced into the interior of the outer shell 1 through the mounting seat 2, thereby realizing the heat dissipation function. In this process, the air will first be initially filtered through the filter screen 1 4 to remove larger impurities and particles, and then the air that has been initially filtered will continue to be further filtered through the filter plate 6 below, thereby ensuring that the air entering the interior of the outer shell 1 is purer. In order to facilitate the cleaning or replacement of the filter plate 6, when the triangular push plate 8 is pressed, it will slide between the two trapezoidal slide plates 9, and at the same time stretch the spring 23, and use the inclined surfaces on both sides of the triangular push plate 8 to release the air. The side design pushes the two trapezoidal slides 9 to move in the opposite direction, and applies pressure to the L-shaped slide 10, so that it drives the block 13 to move. When the block 13 is completely moved out of the interior of the sliding plate 5, the filter plate 6 can be easily taken out for cleaning by pulling the sliding plate 5. When installing the filter plate 6, it is only necessary to insert the sliding plate 5 and the filter plate 6 in their original positions. At this time, the spring 12 pushes the block 13 to be stuck into the interior of the sliding plate 5, thereby realizing fast and stable installation, which not only realizes efficient filtration of the heat dissipation air, but also greatly simplifies the cleaning and replacement process of the filter plate 6, and improves the usability and maintenance efficiency of the equipment.

[0026] Reference Figure 3 An air inlet hole 3 is provided inside the mounting seat 2, an air exhaust hole 15 is provided inside the outer shell 1, a fixing frame 17 is fixedly connected to the inner wall of the mounting seat 2, a cooling water tank 18 is fixedly connected to the outer wall of the fixing frame 17, a circulating water pipe 19 is fixedly connected to the inner wall of the cooling water tank 18, a fan 14 is fixedly connected to the inner wall of the outer shell 1, and the circulating water pipe 19 is arranged above the fan 14, a cooling plate 21 is fixedly connected to the inner wall of the outer shell 1, and the cooling plate 21 is arranged on the outer wall of the fan 14, a fixed inner plate 20 is fixedly connected to the inner wall of the outer shell 1, and the fixed inner plate 20 is arranged below the fan 14, and a plurality of diversion holes 22 are provided inside the fixed inner plate 20;

[0027] Specifically, when the fan 14 delivers air into the interior of the outer shell 1, cooling water is continuously provided to the circulating water pipe 19 through the cooling water tank 18, ensuring that the cooling water can be evenly distributed throughout the entire air channel, so that the air can be evenly cooled when passing through the channel, effectively improving the heat dissipation efficiency. At the same time, the cooling plate 21 inside the outer shell 1 also plays an important role, further cooling the air that has been treated with cooling water, thereby enhancing the heat dissipation effect. The air that has undergone double cooling treatment is accurately discharged into the interior of the ceiling lamp through the diversion hole 22, ensuring that the air can be evenly distributed to every corner of the ceiling lamp, thereby achieving efficient heat dissipation. Finally, the air that has undergone heat dissipation treatment is smoothly discharged through the exhaust hole 15, completing the entire heat dissipation process, which not only achieves efficient heat dissipation of the ceiling lamp, but also ensures the circulation and circulation of air, providing a guarantee for the stable operation of the ceiling lamp.

[0028] Working principle: When the heat dissipation structure for ceiling lamps is needed, first, when the fan 14 operates, it will send external air into the interior of the outer shell 1 through the mounting base 2 for heat dissipation. During this process, it is preliminarily filtered through the first filter screen 4, then further filtered through the lower filter plate 6. Then, by pressing the triangular push plate 8, it slides between the two trapezoidal slides 9 of the trapezoidal slide plate 9, so that the second spring 23 is stretched. At the same time, through the inclined sides on both sides of the triangular push plate 8, the two trapezoidal slides 9 are pushed to move in the opposite direction, thereby applying pressure to the L-shaped slide 10, causing the L-shaped slide 10 to drive the clamping block 13 to move. When the clamping block 13 completely moves out of the interior of the sliding plate 5, the filter plate 6 can be taken out for cleaning by pulling the sliding plate 5. During installation, only the sliding plate 5 and the filter plate 6 need to be inserted back to their original positions. At this time, the first spring 12 pushes the clamping block 13 to be clamped into the interior of the sliding plate 5 to achieve installation, achieving the effect of efficiently filtering the heat dissipation air;

[0029] In addition, when the fan 14 sends air into the interior of the outer shell 1, during this process, the cooling water tank 18 continuously circulates and inputs cooling water into the circulating water pipe 19, so that the cooling water fills the air passage, and then the air is evenly cooled. Then, it cooperates with the cooling plate 21 inside the outer shell 1 to further cool the air, and then is discharged into the interior of the ceiling lamp through the diversion holes 22 for efficient heat dissipation, and finally discharged through the exhaust holes 15, achieving the effect of heat dissipation.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
