It should be noted that, in order to ensure that the cooling liquid can keep flowing circularly counterclockwise when the sliding plug 7 moves horizontally back and forth, a check valve which only allows the cooling liquid to flow from the return cavity 13 to the right end of the reservoir cavity 5 is installed in the return cavity 13, and a check valve which only allows the cooling liquid to flow from the left end of the reservoir cavity 5 to the cooling cavity 12 is installed at the communication position of the cooling cavity 12 and the left end of the reservoir cavity 5.

Further, the valve group comprises a one-way valve and a pressure valve, wherein the one-way valve only allows cooling liquid to flow from the right end of the liquid storage cavity 5 to the left end of the liquid storage cavity 5, the one-way valve is installed on one side of the liquid outlet hole 8 close to the left end of the liquid storage cavity 5, the pressure valve is installed on one side of the liquid outlet hole 8 close to the right end of the liquid storage cavity 5, and when the sliding plug 7 slides leftwards, the one-way valve only allows the cooling liquid at the left end of the liquid storage cavity 5 to flow into the cooling cavity 12; when the sliding plug 7 slides rightwards, the pressure valve is pressed to be opened, and the cooling liquid flows to the left end of the liquid storage cavity 5 from the right end of the liquid storage cavity 5, so that the anticlockwise circulating flow of the cooling liquid is realized.

The driving mechanism comprises a conductive block 10 which is arranged in the power cavity 6 and is connected with the same circuit with the LED lamp tube 4 in a point mode, permanent magnets 11 are embedded in the inner top and the inner bottom of the power cavity 6, the magnetic poles of the opposite sides of the two permanent magnets 11 are opposite, and one end of the conductive block 10 is fixedly connected with the sliding plug 7 through a sliding rod 9.

It should be noted that the magnetic pole at the upper end of the second magnetic sheet 17 is the same as the magnetic pole at the lower end of each first magnetic sheet 16, so when the second magnetic sheet 17 is located under the first magnetic sheet 16, sufficient repulsion force is generated between the first magnetic sheet and the second magnetic sheet, so as to push the heat conducting rod 15 to slide upwards, and when the second magnetic sheet 17 leaves under the first magnetic sheet 16, the heat conducting rod 15 slides downwards vertically under the action of gravity; further, in order to ensure that the heat conducting rod 15 does not fall into the liquid storage cavity 5 completely, the diameter of the upper end of the heat conducting rod 15 is larger than that of the sliding part thereof, so that the heat conducting rod 15 can be clamped on the heat conducting fins 14 and cannot fall completely.

In this embodiment, when the sliding rod 9 horizontally reciprocates along with the conductive block 10, the second magnetic sheet 17 also horizontally reciprocates along with the sliding rod, so that the second magnetic sheet 17 can be sequentially close to each first magnetic sheet 16, when the second magnetic sheet 17 is located under a certain first magnetic sheet 16, the heat conducting rod 15 at the upper end of the first magnetic sheet 16 can be pushed to slide upwards, the original part of the heat conducting rod 15, which is in contact with the cooling liquid, is directly contacted with air, so as to cool rapidly, when the second magnetic sheet 17 is away from under the first magnetic sheet 16, the heat conducting rod 15 vertically slides downwards, and absorbs heat in the cooling liquid again, so that each heat conducting rod 15 alternately generates ascending and descending actions, thereby accelerating the dissipation rate of heat absorbed by the cooling liquid, so that the cooling liquid always keeps a good cooling and heat dissipation effect, and the heat dissipation effect of the LED lamp can be better.
