[0003] After searching, the announcement number is CN218570105U, and the name is a power adapter with noise reduction effect, including a shell. Through research and analysis, it is found that although it can reduce the noise generated by the power adapter during operation during use, it still has the following disadvantages to a certain extent.

[0004] For example, the surface of the power adapter does not have a structure to block water droplets. Water droplets will enter the power adapter through the gaps and heat dissipation areas, which is not conducive to the operation of the power adapter. In addition, the wires of the power adapter do not have a protective effect. Excessive pulling will cause damage to the wires, which in turn affects the use of the power adapter. In order to solve the above technical problems, we have designed a waterproof power adapter. Utility Model Content

[0021] See also Figure 1-Figure 4 A waterproof power adapter includes a power adapter body 1 and a box body 2. A connecting line 3 is provided on the right side of the power adapter body 1. A heat conducting mechanism 4 is provided on the top of the box body 2. The right side of the box body 2 is fixedly connected to a box body 5. The right side of the inner cavity of the box body 5 is fixedly connected to an auxiliary mechanism 6. A rubber pad 7 is provided on the surface of the connecting line 3. A rubber block 8 is fixedly connected to the surface of the rubber pad 7. A funnel 9 is provided on the surface of the rubber block 8. A waterproof shed 10 is fixedly connected to the top of the box body 5. A heat dissipation hole is opened on the left side of the box body 2. A waterproof breathable membrane 11 is provided in the inner cavity of the heat dissipation hole.

[0022] See also Figure 1 The heat-conducting mechanism 4 includes a first heat-conducting plate 12, which is fixedly embedded in the top of the box body 2. The bottom of the first heat-conducting plate 12 is fixedly connected to a heat-conducting rod 13, and the bottom of the heat-conducting rod 13 is fixedly connected to a second heat-conducting plate 14. By arranging the first heat-conducting plate 12, the heat-conducting rod 13 and the second heat-conducting plate 14, water droplets falling on the top of the box body 2 can play a heat dissipation role, thereby improving the heat dissipation performance of the device. The second heat-conducting plate 14 is connected to the inner cavity of the box body 2 by bolts.

[0023] See also Figure 1 、 Figure 3 and Figure 4 The auxiliary mechanism 6 includes a fixing rod 15, the right side of the fixing rod 15 is fixedly connected to the inner cavity of the box body 5, there are two fixing rods 15, and a spring 16 is provided on the surface of the fixing rod 15. The left side of the spring 16 is fixedly connected to a sleeve plate 17, and the sleeve plate 17 is movably sleeved on the surface of the fixing rod 15. The left side of the fixing rod 15 is fixedly connected to the funnel 9, and the bottom of the sleeve plate 17 is fixedly connected to the rubber block 8 through a vertical rod. The opposite side of the vertical rod passes through the inner cavity of the funnel 9, and the right side of the spring 16 is fixedly connected to the inner cavity of the box body 5. By providing the funnel 9, the rubber pad 7 can play a protective and limiting role when the connecting line 3 is pulled, thereby avoiding damage to the connection between the connecting line 3 and the power adapter.

[0024] See also Figure 1、 Figure 3 and Figure 4 An anti-slip protrusion 18 is provided on the left side of the inner cavity of the rubber pad 7. By providing the anti-slip protrusion 18, the rubber pad 7 and the rubber block 8 can be driven to move to the right when the connecting line 3 is pulled, which is beneficial to the protection process. The right side of the connecting line 3 passes through the box body 5.

[0025] See also Figure 1 、 Figure 2 and Figure 3 The inner cavity of the box body 5 is fixedly connected with a limiting plate 19. By setting the limiting plate 19, the connecting line 3 can be limited to prevent the connecting line 3 at the bending point from blocking the ventilation hole 20. There are two limiting plates 19, and the connecting line 3 is located between the limiting plates 19.

[0026] See also Figure 1 and Figure 2 A ventilation hole 20 is provided at the bottom of the box body 5, and a fan 21 is provided on the left side of the box body 5. By providing the ventilation hole 20 and the fan 21, heat dissipation can be achieved, which is beneficial to the operation of the power adapter.

[0027] See also Figure 1 and Figure 2 A connection hole is provided on the left side of the box body 2, and the power adapter body 1 is located in the inner cavity of the box body 2. By setting the box body 2, the box body 5 and the waterproof shed 10, water droplets can be guided to a position away from the device, which is conducive to improving the waterproof performance.

[0028] When in use, the heat on the surface of the power adapter is high when it is running, and the heat is transferred to the first heat conducting plate 12 through the second heat conducting plate 14 and the heat conducting rod 13 in turn. When water droplets fall on the surface of the first heat conducting plate 12, the temperature of the water droplets is low, which can play a certain heat dissipation role, which is beneficial to the operation of the power adapter. Since the box body 2, the box body 5 and the top of the waterproof shed 10 are all inclined, the water droplets can flow through the box body 2, the box body 5 and the waterproof shed 10 in turn and drip at a position far away from the device, and the waterproof and breathable membrane can prevent water droplets from entering the box body 2. The rubber pad 7 can fill the gap between the connecting line 3 and the box body 5, so that the device has good waterproof performance. The fan 21 is turned on by the external controller. The heat in the box body 2 can be dissipated through the waterproof and breathable membrane 11, further dissipating the heat of the device. When the connecting line 3 is pulled by the outside, it moves to the right, and drives the rubber pad 7 and the rubber block 8 to move to the right through the anti-slip protrusion 18, so that the sleeve 17 drives the spring 16 to compress. Since the space on the right side of the funnel 9 is small, the rubber block 8 can contact and be compressed with the inner cavity of the funnel 9, thereby making the contact between the anti-slip protrusion 18 and the connecting line 3 closer. At the same time, the rebound tendency of the spring 16 is stronger, and the movement of the connecting line 3 to the right is more restricted, thereby avoiding excessive pulling of the connecting line 3 and protecting the connection between the connecting line 3 and the power adapter. After the pulling force disappears, the spring 16 is reset.

[0029] In summary, the waterproof power adapter, through the cooperation of the box body 2, the box body 5, the waterproof shed 10, the waterproof breathable membrane 11, the first heat conducting plate 12, the heat conducting rod 13, the second heat conducting plate 14, the rubber pad 7, the rubber block 8, the funnel 9, the spring 16, the sleeve 17 and the anti-slip protrusion 18, solves the problem that the conventional power adapter does not have the advantage of being waterproof and cannot protect the wires.
