[0022] 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.

[0023] Embodiment 1

[0024] This embodiment is intended to help solve the problem of overheating of the connection between the motor bearing and the rotor caused by long-term high-intensity use of the water pump. Figure 1-4 An upgraded high-efficiency energy-saving water pump includes a motor housing 1, a motor rotor 5 is installed in the motor housing 1, a motor output shaft 6 is installed on one side of the motor rotor 5, a bearing 7 is arranged between the motor rotor 5 and the motor output shaft 6, a fan blade 907 and a heat conducting sheet 904 are installed on one side of the bearing 7 in the motor housing 1, and the motor will generate a certain amount of heat at the bearing 7 during use. The heat conducting sheet 904 can absorb the heat and transfer the heat to the heat exchange box 903, and the fan blade 907 will rotate under the drive of the water flow, thereby realizing the cooling of the hot air around the bearing 7.

[0025] It also includes a water pump housing 2, one side of the water pump housing 2 is connected to a water inlet pipe 3, the side wall of the water pump housing 2 is connected to a water outlet pipe 4, a cooling device 9 is provided on the water outlet pipe 4, one side of the water pump housing 2 is penetrated by the motor output shaft 6, one end of the motor output shaft 6 is fixedly connected to a water pump turbine blade 8.

[0026] The water inlet pipe 3 is connected to the water source through a water pipe, and the water outlet pipe 4 is connected to the water use end through the water pipe, and the transportation and transfer of the water source are realized under the rotation movement of the water pump turbine blade 8. The rate of water source transportation can be controlled by the rotation rate of the water pump turbine blade 8. The cooling device 9 is arranged on the water outlet pipe 4 to cool the bearing 7 of the motor housing 1 while pumping water, and the heat generated by the bearing 7 is taken away by the flow of water, so as to improve the service life of the water pump.

[0027] The cooling device 9 includes a return pipe inlet 901, which is connected to the water outlet pipe 4. One end of the return pipe inlet 901 is connected to a heat exchange box 903, and one side of the heat exchange box 903 is connected to a return pipe outlet 902. The return pipe outlet 902 is connected to the water outlet pipe 4. The design that the return pipe inlet 901, the return pipe outlet 902 and the heat exchange box 903 are connected to the water outlet pipe 4 makes the cooling process always in a flowing state, and the hot air in the motor housing 1 can be quickly taken away by the flow of water.

[0028] A rotating groove 908 is provided at the bottom of the heat exchange box 903, and a fan shaft 905 is rotatably connected in the rotating groove 908. One end of the fan shaft 905 located inside the heat exchange box 903 is fixedly connected to a fan turbine blade 906, and the other end of the fan shaft 905 is fixedly connected to a fan blade 907. Driven by the water pump turbine blade 8, the water in the return pipe inlet pipe 901, the return pipe outlet pipe 902 and the heat exchange box 903 is in motion. The movement of water can drive the rotation of the fan turbine blade 906 located in the heat exchange box 903, and through the connection of the fan shaft 905, the fan blade 907 can be driven to rotate, thereby achieving the diffusion of hot air around the bearing 7, and then achieving the cooling of the motor.

[0029] The heat exchange box 903 is located on one side of the fan blade 907 and is fixedly connected to a heat conductive sheet 904, which is used to absorb the hot air generated around the bearing 7 and accelerate the diffusion speed of the hot air around the bearing 7 under the rotation of the fan blade 907, so that the heat conductive sheet 904 can quickly absorb the heat generated by the bearing 7.

[0030] A No. 1 one-way valve 10 is installed in the return pipe inlet 901, and a No. 2 one-way valve 11 is installed in the return pipe outlet 902. The design of the No. 1 one-way valve 10 and the No. 2 one-way valve 11 is to prevent water from entering the heat exchange box 903 through the return pipe outlet 902 and then being discharged through the return pipe inlet 901, thereby limiting the flow direction of water, so that the water is divided into two sections from the return pipe inlet 901, one section is output through the outlet pipe 4, and the other end enters the return pipe inlet 901 through the No. 1 one-way valve 10, and then is output through the return pipe outlet 902 and returns to the outlet pipe 4.

[0031] Embodiment 2

[0032] This embodiment is intended to help solve the problem that the fan shaft may shake up and down when rotating in the rotating groove. This embodiment is an explanation based on the first embodiment.

[0033] The design of the limiting device 12 can effectively limit the movement of the fan shaft 905, so that the fan shaft 905 can only rotate in the rotation groove 908, preventing the fan shaft 905 from shaking up and down, thereby ensuring the stability of the cooling process.

[0034] Embodiment 3

[0035] This embodiment is intended to help solve the problem of poor sealing of the fan shaft during rotation. This embodiment is an explanation based on the second embodiment. For details, please refer to Figure 1-4 A sealing ring 13 is installed in the rotating groove 908. The design of the sealing ring 13 effectively ensures the sealing of the rotating groove 908, preventing the water in the heat exchange box 903 from being discharged through the rotating groove 908, thereby causing damage to the motor.
