Because the silicone bag 2 is a flexible material, when the silicone bag 2 is used to cool the lamp tube 1, the contact area with the lamp tube 1 can be increased, thereby improving the cooling speed, one end of the water inlet pipe 4 is fixedly connected to a drain pipe 5 for discharging clean water from the silicone bag 2, and two groups of clamping structures 6 for limiting the silicone bag 2 are fixedly connected to the top of the shell 3.

[0022] See also Figure 2 A limit baffle 201 is fixedly connected to the top of the silicone bag 2 for limiting the position of the silicone bag 2, and the limit baffle 201 prevents the silicone bag 2 from falling and bending downward due to the amount of water inside. Both ends of the limit baffle 201 are fixedly connected to the inner cavity of the shell 3, and the end of the limit baffle 201 away from the silicone bag 2 is also fixedly connected to the inner cavity of the shell 3. The end of the limit baffle 201 close to the silicone bag 2 is semicircular, so that when it contacts the silicone bag 2, the scratches on the silicone bag 2 are reduced, thereby extending the service life of the silicone bag 2.

[0023] See also Figure 2The outer wall of the silicone bag 2 is slidably connected with a limiting ring 202 for limiting the silicone bag 2, and the limiting ring 202 is provided with a total of multiple groups and horizontally arrayed in the inner cavity of the shell 3, and a tension spring 203 is fixedly connected between the limiting ring 202 and the limiting ring 202. Specifically, the inner cavity of the shell 3 is provided with a strip groove 204 for providing sliding of the limiting ring 202, and the limiting ring 202 is slidably connected to the inner cavity of the strip groove 204, and the end of the silicone bag 2 away from the limiting ring 202 is fixedly connected with a connecting plate 205, and the end of the connecting plate 205 away from the silicone bag 2 is fixedly connected with a reset spring 206 between the shell 3, so that when the silicone bag 2 is not filled with water, the reset spring 206 uses the connecting plate 205 to pull the silicone bag 2 to fold, and when water enters the silicone bag 2, the silicone bag 2 will be propped up by the water, thereby unfolding, and continuously filling water, so that the length of the unfolded silicone bag 2 is consistent with the length of the lamp tube 1, so that it is more suitable for lamp tubes 1 of different lengths and shapes.

[0024] Example 2: Please refer to Figure 3 - Figure 4 The clamping structure 6 includes a bent plate 601, which is rotatably connected to the top of the shell 3. A rubber roller 602 for contacting an object is fixedly installed inside the bent plate 601, and the material characteristics of the rubber roller 602 are used to increase friction when clamping the object, thereby reducing the risk of shaking of the shell 3. Specifically, a fixed shaft 603 is fixedly connected inside the bent plate 601, and the rubber roller 602 is fixedly sleeved on the outer wall of the fixed shaft 603. An extension block 604 is rotatably connected to the outer wall of the bent plate 601. A support shaft 605 for providing rotation of the bent plate 601 is fixedly connected inside the extension block 604, and the bent plate 601 is rotatably sleeved on the outer wall of the support shaft 605.

[0025] See also Figure 3 - Figure 4 The bottom of the bent plate 601 is rotatably connected to a push plate 606 for pushing the bent plate 601 to flip, and the outer wall of the push plate 606 is slidably connected to a sleeve rod 607 for pushing the push plate 606 to move up and down.

A column rod 609 is fixedly connected in between for providing rotation of the sleeve rod 607. The sleeve rod 607 is rotatably sleeved on the outer wall of the column rod 609, so that after water enters the sleeve rod 607, the push plate 606 is pushed upward, and the push plate 606 uses the rotating block 611 to push the bent plate 601 to flip and close. When the water flow inside the sleeve rod 607 is discharged, the push plate 606 will move downward due to the loss of support at the bottom, and use the rotating block 611 to pull the bent plate 601 to flip and unfold.

[0026] See also Figure 2 - Figure 3The two groups of rods 607 are connected by a connecting pipe 612. One end of one group of rods 607 away from the connecting pipe 612 is fixedly connected to a diversion pipe 613. The bottom of the diversion pipe 613 is fixedly connected to the top of the drain pipe 5, so that the water inside the drain pipe 5 enters the inside of one group of rods 607 through the diversion pipe 613, and then uses the connecting pipe 612 to make the water flow into the inner cavity of the other group of rods 607.

[0027] The working principle of the utility model is:

[0028] First, place the silicone bag 2 on the top of the lamp tube 1. After the water flows into the silicone bag 2 through the water inlet pipe 4, the silicone bag 2 is propped up and unfolded so that the silicone bag 2 fits the top of the lamp tube 1, and the internal cold water is used to cool the lamp tube 1. At the same time, the drain pipe 5 can discharge the heated water in the silicone bag 2 from the silicone bag 2, so that a part of the water enters the diversion pipe 613 and enters the inside of a group of sleeve rods 607, and then uses the connecting pipe 612 to make the water flow into the inner cavity of another group of sleeve rods 607. After the water enters the inside of the sleeve rod 607, the push plate 606 is pushed upward, so that the push plate 606 uses the rotating block 611 to push the bent plate 601 to flip and close, and clamp it on the outer wall of the object to fix the silicone bag 2.
