The mounting blocks 303 are fixed by multiple sets of second fixing screws 304, so that the end cover 3 is installed on the front end of the motor body 1. At the same time, after the end cover 3 is installed, the sealing gasket 302 can ensure the sealing between it and the motor body 1 to prevent the infiltration of water and dust.

[0028] Furthermore, a water guide groove 401 is provided at the top of the drainage groove 4, and a drainage cover 402 is threadedly connected to the bottom of the end cover 3 and located on the outside of the drainage groove 4. When the output shaft 2 is working, even if water enters through the gap on the outside of the output shaft 2, the water can be guided by the water guide groove 401, and then the water is accumulated on the inside of the drainage groove 4. The water can be discharged by opening the drainage cover 402, thereby preventing water from entering the interior of the motor body 1, thereby improving the service life of the motor body 1.

[0029] Secondly, the front end of the connecting sleeve 5 is fixedly connected to the output shaft 2 by the third fixing screw 501, and the inner side of the protective cover 6 is provided with a docking groove 601 adapted for use with the protective convex ring 7.

The protective cover 6 can protect the gap between the output shaft 2 and the end cover 3 to prevent the entry of water and dust. At the same time, the protective convex ring 7 can further block water and dust, thereby greatly improving the waterproof and dustproof effect.

[0030] Finally, the bottom end of the inner side of the junction box 8 is fixedly connected to the motor body 1 by multiple groups of fourth fixing screws 801, a first sealing ring 802 is provided between the junction box 8 and the motor body 1, and a terminal head 803 is threadedly connected to the back of the junction box 8. The sealing cover 9 is fixedly connected to the junction box 8 by multiple groups of fifth fixing screws 901, and a second sealing ring 902 is provided between the sealing cover 9 and the junction box 8. The junction box 8 is installed on the outside of the motor body 1 by the fourth fixing screws 801. The first sealing ring 802 can ensure the sealing between the junction box 8 and the motor body 1, and the motor body 1 is wired through the terminal head 803. The sealing cover 9 is installed on the top of the junction box 8 by the fifth fixing screws 901, and it is opened to facilitate wiring and maintenance operations. At the same time, the second sealing ring 902 can ensure the sealing between the sealing cover 9 and the junction box 8.

[0031] In this embodiment, the implementation scenario is specifically as follows: the end cover 3 is connected to the water pump casing through the front mounting hole 301, and the mounting block 303 is fixed by multiple sets of second fixing screws 304, so that the end cover 3 is installed on the front end of the motor body 1. At the same time, after the end cover 3 is installed, the sealing gasket 302 can ensure the sealing between it and the motor body 1 to prevent the infiltration of water and dust.

At the same time, the protective convex ring 7 can further block water and dust. When the output shaft 2 is working, even if water enters through the gap on the outside of the output shaft 2, the incoming water can be guided through the water guide groove 401 Towards, water accumulates on the inner side of the drain groove 4, and the drain cover 402 can be opened to drain the water, thereby preventing water from entering the interior of the motor body 1. The junction box 8 is installed on the outside of the motor body 1 by the fourth fixing screw 801, and the first sealing ring 802 can be used to ensure the sealing between the junction box 8 and the motor body 1. The motor body 1 is wired through the terminal head 803, and the sealing cover 9 is installed on the top of the junction box 8 by the fifth fixing screw 901. It is opened for convenient wiring and maintenance operations. At the same time, the second sealing ring 902 can be used to ensure the sealing between the sealing cover 9 and the junction box 8. The whole operation process is simple and convenient. Compared with the existing water pump motor, the utility model greatly improves the waterproof and dustproof effect of the water pump motor through design, effectively prevents the entry of water and dust, and improves the service life of the water pump motor.
