[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 4 As shown, the utility model provides a protective power adapter, including a main body 1, two ends of the main body 1 are fixedly connected with a power cord 2, two sides of the main body 1 are fixedly connected with a fixing block 3, the inside of the fixing block 3 is slidably connected with a plug 4, the outside of the plug 4 is slidably connected with a heat insulation column 5, the end of the heat insulation column 5 is internally spirally connected with a pentagonal bolt 6, the outside of the pentagonal bolt 6 is slidably connected with a sun visor 7, the pentagonal bolt 6 penetrates the sun visor 7, the end of the pentagonal bolt 6 is spirally connected with a pentagonal nut 18, the top of the main body 1 is fittedly connected with a heat sink 8, the top of the heat sink 8 is fixedly provided with a heat sink 10, and the heat sink 10 is vertically fixed on the heat sink 8 to evenly disperse heat from the heat sink 8 to ensure safe operation of the power adapter.

[0023] Specifically, a waterproof base 16 is fixedly provided on the outer side of the main body 1, and a waterproof top cover 17 is fixedly connected to the top of the waterproof base 16. The waterproof base 16 and the waterproof top cover 17 are made of silicone material, which can protect the power adapter from being damaged if it is accidentally dropped.

[0024] Furthermore, a latch 4 is slidably connected to the top of the waterproof base 16, and a latch 4 is slidably connected to the bottom of the waterproof top cover 17. Both the waterproof base 16 and the waterproof top cover 17 are fixed by the latch 4, which increases the stability of the device and facilitates disassembly.

[0025] Furthermore, a temperature sensor 11 is fixedly connected to one side of the main body 1, a transmission line 12 is fixedly set on one side of the temperature sensor 11, one end of the transmission line 12 is fixedly connected to a motor 13, one side of the motor 13 is fixedly connected to a ventilation duct 14, and an air outlet 15 is fixedly set on the outside of the ventilation duct 14. In windless conditions, the heat dissipation efficiency of the heat sink 10 is reduced, the temperature sensor 11 transmits a signal to the motor 13, and the motor 13 blows air to the heat sink 10 through the ventilation duct 14, thereby reducing the temperature of the adapter.

[0026] It is worth noting that the inside of the heat sink 8 is spirally connected with a hexagonal bolt 9, and the hexagonal bolt 9 is spirally connected to the main body 1. The hexagonal bolt 9 fixes the heat sink 8 on the main body, thereby increasing the stability of the heat sink 10.

[0027] It is worth noting that the included angle between the sun visor 7 and the heat-insulating column 5 is 90°, and the sun visor 7 is set to be black. The black color will absorb the heat brought by the sunlight. The heat is isolated in the heat-insulating column 5 and will not be transferred to the power adapter.

[0028] Among them, the main body 1, the heat sink 8, the heat sink 10, the motor 13, and the temperature sensor 11 are existing technologies and will not be described in detail; at the same time, the utility model also includes a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0029] Working principle and process: When the staff uses the protective adapter, if it encounters rainy or snowy weather, they can put the main body 1 into the waterproof base 16, then cover the main body 1 with the waterproof top cover 17, and use the plug 4 to insert the waterproof base 16 and the waterproof top cover 17. In hot weather, the current enters with the power cord 2, and heat is generated when the current passes through. The plug 4 can be used to slide the insulation column 5 and the fixing block 3 together, and then the sun visor 7 is placed in a suitable position on the heat sink 10, and the pentagonal bolt 6 is passed through the insulation column 5 and the sun visor 7. The pentagonal nut 18 is rotated at the end of the pentagonal bolt 6 to fix the sun visor 7 and the insulation. Column 5, use hexagonal bolts 9 to fix the heat sink 8 on the top of the main body 1, and the heat sink 10 is vertically fixed on the heat sink 8. The air passing through the surface of the heat sink 10 will take away a lot of heat to cool the adapter. If there is windless weather, the air flow rate is slow and the heat accumulates quickly. When the temperature is higher than the set temperature, the temperature sensor 11 will transmit the signal to the motor 13 through the transmission line 12. The motor 13 will operate and blow air to the surface of the heat sink 10 through the ventilation duct 14 to the air outlet 15, thereby accelerating the air flow rate and the heat dissipation, so that the adapter temperature is lower than the dangerous value, eliminating the risk of the power cord fusing due to excessive temperature.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
