It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] like Figure 1-Figure 5 As shown, it is a structural diagram of a heat dissipation device of a stage lamp provided by an embodiment of the present invention, comprising a barrel 1, a shell 10, a positioning seat 2, heat dissipation fins 5, an air guide system 100, a separation storage mechanism 200 and a self-cleaning mechanism 300, wherein the shell 10 is arranged on the outside of the barrel 1, the positioning seat 2 is arranged inside the barrel 1, and a lamp body 3 is mounted on the positioning seat 2; the heat dissipation fins 5 are evenly distributed on the outside of the positioning seat 2, and a plurality of heat dissipation fins 5 are connected to a heat conducting plate 4 arranged on the inside of the barrel 1, so as to facilitate the heat dissipation of the lamp body. 3 when working, the heat generated is quickly transferred outward; the air guide system 100 is arranged on the barrel body 1 and the shell 10, and is used to take the heat out when the air flows; the separation storage mechanism 200 is arranged at the bottom end of the shell 10, and the separation storage mechanism 200 is also in contact with the air cylinder 6 in the air guide system 100, and forms an independent storage space for storing the separated liquid; the self-cleaning mechanism 300 is arranged on both sides of the air cylinder 6, filters the air entering the device, and automatically cleans the dust attached to the surface during filtering.

[0039] In one embodiment of the present invention, a connecting pipe is installed at the bottom end of the outer cylinder 19 during actual use, and a valve body is arranged on the connecting pipe to control the amount of liquid discharged from the storage chamber 21, thereby achieving regular discharge of the liquid in the storage chamber 21.

[0040] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, the air guide system 100 includes a wind tube 6, a rotating shaft 1 7, a fan blade 1 8, an air guide port 9, a rotating shaft 2 11 and a fan blade 2 12;

[0041] The wind tube 6 is arranged at the bottom of the barrel body 1, and a rotating shaft 7 is rotatably installed in the wind tube 6, and a fan blade 8 is installed at the end of the rotating shaft 7;

[0042] The air guide port 9 is arranged on the barrel body 1 so that the chambers inside and outside the barrel body 1 are connected;

[0043] The second rotating shaft 11 is rotatably installed in the chambers of the barrel body 1 and the outer shell 10, and a plurality of second fan blades 12 are arranged on the second rotating shaft 11 along the axial direction.

[0044] In one embodiment of the present invention, the rotating shaft 7 is driven by an independently arranged micro motor. When the rotating shaft 7 rotates, external air is sucked into the wind tube 6. The fan blade 8 rotates to transport wind along the surface of the heat conduction plate 4 to cool the multiple heat dissipation fins 5. When the air moves to the end of the heat conduction plate 4, it enters the chamber between the barrel body 1 and the outer shell 10 along the air guide port 9, and when the rotating shaft 11 and the fan blade 12 rotate, the flow of gas can be accelerated.

[0045] like Figure 1 and Figure 3 As shown, as another preferred embodiment of the present invention, the rotating shaft 1 7 and the rotating shaft 2 11 are also connected and driven by a synchronous driving unit arranged in the barrel body 1;

[0046] The synchronous drive unit includes a driving gear 13, a connecting gear 14 and a driven gear 15;

[0047] The driving gear 13 is fixedly mounted on the rotating shaft 1 7, and the driven gear 15 is fixedly mounted on the rotating shaft 2 11, and the driving gear 13 and the driven gear 15 are in the same horizontal plane;

[0049] In one embodiment of the present invention, in order to increase the air flow rate when the driving gear 13 rotates, a number of evenly distributed through holes can be appropriately opened on the surface of the driving gear 13. In addition, when the rotating shaft 17 rotates in the wind tube 6, the driving gear 13 moves synchronously therewith, and since the driving gear 13 and the driven gear 15 are both meshed with the connecting gear 14, and the adjacent connecting gears 14 are in a meshing state, when the rotating shaft 17 rotates, the driving gear 13, the connecting gear 14 and the driven gear 15 can be driven to rotate synchronously in sequence, thereby driving the rotating shaft 2 11 and the fan blade 2 12 to rotate.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the separation storage mechanism 200 includes a condensation separator 16, a liquid outlet pipe 17, a gas outlet pipe 18, an outer cylinder 19, a filling port 20 and a storage chamber 21;

[0051] The condensation separator 16 is arranged at the gas guide end of the barrel body 1 and the shell 10, and a liquid outlet pipe 17 and a gas outlet pipe 18 are respectively installed on both sides of the condensation separator 16;

[0052] The outer cylinder 19 is arranged outside the wind cylinder 6, and a storage chamber 21 is formed between the wind cylinder 6 and the outer cylinder 19;

[0053] The outer cylinder 19 is provided with a filling port 20 , which is communicated with the end of the liquid outlet pipe 17 so as to inject the separated liquid into the storage chamber 21 .

[0054] In one embodiment of the present invention, after the air enters the condensation separator 16 along the chamber of the barrel body 1 and the outer shell 10, it is cooled and separated by the condensation separator 16, the gas is discharged outward along the gas outlet pipe 18, and the liquid flows along the liquid outlet pipe 17 and enters the storage chamber 21 through the filling port 20.

[0055] like Figure 1 , Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the self-cleaning mechanism 300 includes a filter screen 22, a rotating shaft 3 23, a positioning shaft 1 24, a positioning shaft 2 25, a pulley 26 and a synchronous belt 27;

[0056] The filter screen 22 is arranged inside the air cylinder 6, and the rotating shaft 3 23 is arranged inside the storage chamber 21, and moves synchronously with the air guide system 100;

[0057] The positioning shaft 1 24 and the positioning shaft 2 25 are both rotatably mounted on the inner side of the outer cylinder 19, and the end of the positioning shaft 1 24 is transmission-connected to the bottom end of the rotating shaft 3 23 through a bevel gear set, the bevel gear set includes a bevel gear 1 and a bevel gear 2, the bevel gear 1 and the bevel gear 2 are in a meshing state, the bevel gear 1 is fixedly connected to the bottom end of the rotating shaft 3 23, and the bevel gear 2 is fixedly connected to the end of the positioning shaft 1 24;

[0058] The positioning shaft 1 24 and the positioning shaft 2 25 are both equipped with pulleys 26 , and the plurality of pulleys 26 are connected through a synchronous belt 27 .

[0059] In one example of the present invention, the top end of the rotating shaft three 23 is connected to the connecting gear 14 installed in the barrel body 1, so that the rotating shaft three 23 can be driven to rotate synchronously when the connecting gear 14 rotates. The rotating shaft three 23 also drives the positioning shaft 1 24 and the pulley 26 to rotate along the outer cylinder 19 through the bevel gear 1 and the bevel gear 2. The synchronous belt 27 absorbs the dust adhered to the filter screen 22 during the rotation of the pulley 26. When the dust enters the storage chamber 21, it comes into contact with the liquid stored inside, and the dust dissolves in the liquid. In addition, in order to prevent the liquid from being discharged outward, the height of the liquid must be lower than the top of the groove for the synchronous belt 27 to pass through.

[0060] like Figure 3 and Figure 4As shown, as another preferred embodiment of the present invention, two grooves for the synchronous belt 27 to pass through are opened on the wind tube 6 along the longitudinal direction, and a sealing ring 28 is installed in the groove at the bottom end to prevent liquid leakage.

[0061] In an example of the present invention, the outer surface of the synchronous belt 27 contacts the bottom end of the filter 22, and the outer side of the synchronous belt 27 is arranged with velvet to increase the contact area and improve the dust adsorption effect.

[0062] In summary, when the lamp body 3 is working, the heat is transferred outward through the positioning seat 2, the heat conducting plate 4 and the heat dissipation fins 5, and the independently arranged micro-motor drives the rotating shaft 7 and the fan blade 8 to rotate. The air filtered by the filter 22 enters the interior of the device along the inner wall of the wind tube 6, and the heat is discharged outward in the process of moving along the heat conducting plate 4. When the air moves to the end of the heat conducting plate 4, it enters the chamber between the barrel 1 and the shell 10 along the air guide port 9. When the rotating shaft 7 rotates in the wind tube 6, the driving gear 13 moves synchronously therewith, and because the driving gear 13 and the driven gear 15 are all meshed with the connecting gear 14, and the adjacent connecting gears 14 are in a meshing state, the driving gear 13, the connecting gear 14 and the driven gear 15 can be driven to rotate synchronously in turn when the rotating shaft 7 rotates, and then the rotating shaft 2 11 and the fan blade 2 12 are driven to rotate, which can accelerate the flow of gas, and the air enters the condensation separator 1 along the chamber of the barrel 1 and the shell 10. 6, after being cooled and separated by the condensation separator 16, the gas is discharged outward along the gas outlet pipe 18, and the liquid flows along the liquid outlet pipe 17 and enters the storage chamber 21 through the filling port 20. When the connecting gear 14 rotates, the rotating shaft 3 23 is driven to rotate synchronously. The rotating shaft 3 23 also drives the positioning shaft 1 24 and the pulley 26 to rotate along the outer cylinder 19 through the bevel gear 1 and the bevel gear 2. The synchronous belt 27 absorbs the dust adhered to the filter screen 22 during the rotation of the pulley 26. When the dust enters the storage chamber 21, it contacts with the liquid stored inside, and the dust dissolves in the liquid. The heat dissipation device has the characteristics of high heat dissipation efficiency, and can quickly discharge the heat generated by the lamp body 3 during operation to avoid the occurrence of excessively high internal ambient temperature, thereby ensuring the stable operation of the device. At the same time, the liquid separated by heat dissipation condensation can be used to automatically clean the dust from the source, thereby reducing the difficulty of cleaning under the premise of effectively preventing dust from entering the device.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
