A plurality of communicating intake pipes 3 are fixedly connected and communicated between the buckling sealing cover 2 and the circulating cooling cover 1. A first cooling fan 6 is fixedly connected to the outer wall of the buckling sealing cover 2. Through such a design, the opening of the buckling sealing cover 2 is buckled and sleeved at the end of the motor, so that under the rotation of the first cooling fan 6, air negative pressure is generated, and the air is pressurized through the communicating intake pipes 3, thereby increasing the air flow rate and intake volume entering the motor and improving the cooling effect of the motor;A plurality of third heat dissipation fins 7 are fixedly connected to the inner wall of the snap-on sealing cover 2, an installation limiting ring 8 is fixedly connected around the inner wall of the circulating cooling cover 1, an intermediate partition plate 15 is horizontally fixedly connected to the inner wall of the circulating cooling cover 1, and a cooling water container 9 is snap-connected between the right side of the installation limiting ring 8, the intermediate partition plate 15 and the inner wall of the circulating cooling cover 1. A protective rear cover 4 is detachably fixedly connected to the left opening of the circulating cooling cover 1, and air intake holes 5 are evenly arranged on the protective rear cover 4. Through such a design, the cooling water container 9 can achieve stable snap connection. A plurality of ultrasonic atomizing sheets 11 are fixedly connected to the atomizing partition plate 10 through holes opened on the atomizing partition plate 10 which is horizontally and hermetically spaced and fixedly connected to the inner wall of the circulating cooling cover 1. A second circulating fan 13 is fixedly connected to the side wall of the circulating cooling cover 1 through a hole, and the second circulating fan 13 is in a waterproof state. A guiding channel 12 is provided on the side wall of the circulating cooling cover 1 corresponding to the second circulating fan 13, and the lower opening of the guiding channel 12 is located between the atomizing partition plate 10 and the cooling water container 9. A first collecting hole 14 is opened at the upper end of the cooling water container 9, a second collecting hole 16 is provided on the intermediate partition plate 15 corresponding to the first collecting hole 14, and a bow-shaped sealing plate 19 is snap-connected to the intermediate partition plate 15.

At the same time, after the atomized water absorbs heat, it rises and moves into the bow-shaped sealing plate 19 under the air negative pressure generated by the rotation of the second circulating fan 13, so that the heat generated by the first heat dissipation fins 20 and the second heat dissipation fins 21 is transferred to the air by the air flow generated by the rotation of the third heat dissipation fan 22 and exchanges heat with the atmosphere, achieving the cooling effect. At the same time, after the high-temperature atomized water cools down to form liquid water, it converges inward along the inclined bow-shaped sealing plate 19 and reaches the guiding collecting pipe 17 through the circulating communication pipe 18, enters the cooling water container 9 through the second collecting hole 16 and the intermediate partition plate 15, thus realizing the water mist circulation work and heat circulation work inside the circulating cooling cover 1 and achieving the purpose of reducing the air temperature entering the motor.
