At the same time, push plate 914 drives gear 918 on rotating lever 917 to move back and forth. Since gear 918 is meshed with gear plate 915, the gear... Gear 918 rotates, causing gear 918 to drive rotating rod 917 to rotate. Rotating rod 917 drives cam 933 to rotate. Cam 933 drives arc block 932 to move up and down repeatedly.

Under the action of spring 930, moving block 927 moves up and down repeatedly. Moving block 927 drives inclined plate 925 to rotate. Due to the inclined and symmetrical structure of inclined plates 925 on the left and right sides, inclined plate 925 drives fixed ring 922 on control block 923 to rotate. Fixed ring 922 drives rotating tube 919 to rotate. Rotating tube 919 drives branch tube 920 to rotate, which facilitates the branch tube 920 to stir the cold airflow, facilitates the uniform distribution of the cold airflow, and increases the heat dissipation effect of the cold airflow on LED beads 6.

[0035] Example 2:

[0036] Based on Example 1, such as Figure 1 - Figure 9As shown, a connecting pipe 941 is fixedly connected to the rear side of the heat sink 5, and the connecting pipe 941 communicates with the rotating pipe 919. A conveying pipe 942 is fixedly connected to the outer side of the connecting pipe 941. An air box 934 is fixedly connected to the rear side of the heat sink 5. A piston plate 935 is provided on the inner side of the air box 934. A reciprocating rod 937 is fixedly connected to the upper side of the piston plate 935. The upper end of the reciprocating rod 937 passes through the upper side of the air box 934 and is fixedly connected to a top plate 938.

The outer side of the air outlet pipe 940 and the air inlet pipe 936 are connected. Each side is equipped with a one-way valve. During heat dissipation, the lifting plate 907 moves up and down repeatedly. The lifting plate 907 drives the L-shaped block 939 to move up and down, the L-shaped block 939 drives the top plate 938 to move, the top plate 938 drives the reciprocating rod 937 to move up and down repeatedly, and the reciprocating rod 937 drives the piston plate 935 to move up and down repeatedly. When the piston plate 935 descends, the one-way valve on the air inlet pipe 936 allows external cooling gas to enter the air box 934. When the piston plate 935 rises, the one-way valve on the air outlet pipe 940 allows cold air to enter the connecting pipe 941. Through the conveying pipe 942, the cold air is distributed to multiple rotating pipes 919 and passed through the air outlets 921 on multiple branch pipes 920 to enter the cold air flow, thereby increasing the heat dissipation effect of the cold air on the LED beads 6.

[0037] Working principle: In use, the operator first starts the air pump 11 to allow cold air to enter the heat dissipation box 5, and starts the motor 912. The motor 912 drives the control lever 911 to rotate. Under the action of the control board 2 910, control board 1 908, lifting plate 907 and rotating plate 904, the moving plate 902 is controlled to move back and forth repeatedly. Under the action of the moving lever 901, the push plate 914 is controlled to move back and forth to facilitate the propulsion of the cold air. The push plate 914 drives the gear plate 915 to move back and forth. With the help of the gear 918, rotating rod 917, cam 933, arc block 932, L-shaped plate 931 and moving block 92, the cold air is pushed forward and backward. 7. Under the action of the inclined plate 925, control block 923 and fixing ring 922, the branch pipe 920 on the control tube 919 can rotate repeatedly in both directions, making the cold air distribution more uniform and increasing the heat dissipation effect. At the same time, the lifting plate 907 drives the L-shaped block 939 to move. Under the action of the top plate 938, reciprocating rod 937, piston plate 935, air inlet pipe 936, air outlet pipe 940, connecting pipe 941 and conveying pipe 942, the air outlet 921 on the branch pipe 920 discharges cold air into the cold air flow, which facilitates the cold air to dissipate heat from the LED beads 6 and enhances the heat dissipation effect of the LED beads 6.
