[0030] Furthermore, the heat dissipation holes 13 are inclined upward from inside to outside, so that after the external water stains contact the sealed housing 1, they will enter the cavity 11 through the heat dissipation holes 13, so that a humid environment can be formed in the cavity 11, which can absorb the heat absorbed by the heat sink 12 and further improve the heat dissipation effect;

[0031] Furthermore, a guide hole 14 is opened at the bottom of the cavity 11 corresponding to the outside of the sealed shell 1. The guide hole 14 is inclined downward. Water stains entering the cavity 11 can be discharged through the guide hole 14, making the water stains flow, further improving the heat dissipation effect of the motor body 3.

[0032] like Figure 1-3 As shown;

[0033] The sealing housing 1 is provided with a mounting groove 16, and the sealing cover 2 is threadedly fixedly connected to the mounting groove 16, so that the motor body 3 inside the sealing housing 1 is sealed, and a sealing ring 7 and a shaping plate 6 are sequentially arranged from top to bottom between the sealing cover 2 and the bottom of the mounting groove 16;

[0034] Furthermore, the outer periphery of the shaping plate 6 is bent, the shaping plate 6 covers the tail of the motor body 3, the sealing ring 7 is located between the shaping plate 6 and the sealing cover 2, and a wedge-shaped portion 22 is correspondingly provided at the bottom of the sealing cover 2. The sealing ring 7 is bent by utilizing this bent shape, thereby improving the sealing performance of the sealing cover 2;

[0035] Furthermore, a groove 17 is formed in an annular shape on the side wall of the mounting groove 16, and a portion of the sealing ring 7 is clamped in the groove 17, so that the sealing ring 7 blocks the shaping plate 6, further improving the sealing effect between the sealing cover 2 and the sealing housing 1;

[0036] Furthermore, the sealing cover 2 has a conical cross section, so that water stains falling onto the sealing cover 2 will slide down along the surface of the sealing cover 2, thereby effectively preventing the water stains from entering the sealing housing 1, further improving the sealing performance.

[0037] like Figure 1 As shown;

[0038] A circular plate 4 is provided on the periphery of the sealing shell 1, and ear plates 21 are evenly provided on the periphery of the sealing cover 2.
