The utility model aims to provide a water pump and a cleaning machine with the same.
Fig. 1 is a schematic cross-sectional structure diagram of a water pump according to a first embodiment of the present invention, fig. 2 is a schematic exploded structure diagram of the water pump in fig. 1, and fig. 3 is a schematic connection relationship diagram between a first driving wheel and a second driving wheel in fig. 1. As shown in fig. 1 to 3, a water pump according to a first embodiment of the present invention includes a motor 10 and a pump body 20, a first driving wheel 12 is disposed on an output shaft 11 of the motor 10, a second driving wheel 22 is disposed on a cylinder rotating shaft 21 of the pump body 20, and the first driving wheel 12 and the second driving wheel 22 are power-connected through a driving belt 30, such as a V belt.
In this embodiment, the first driving wheel 12 of the motor 10 is connected to the second driving wheel 22 of the cylinder shaft 21 through the driving belt 30, which enables the first driving wheel 12 and the second driving wheel 22 to be separately disposed, thereby reducing noise and vibration generated by meshing between gears in a conventional driving manner, and enabling the water pump to have better vibration and noise reduction performance.
Further, in the present embodiment, a first housing 13 is formed at an end of the motor 10 facing the pump body 20, a second housing 23 is formed at an end of the pump body 20 facing the motor 10, a connecting member, such as a bolt and a nut, connects the first housing 13 and the second housing 23, the first housing 13 and the second housing 23 are combined to form an accommodating cavity 40, and the first driving wheel 12, the second driving wheel 22 and the driving belt 30 are disposed in the accommodating cavity 40.
An output shaft 11 of the motor 10 penetrates through a first shell 13 to be connected with a first driving wheel 12, and a first reinforcing rib 14 is formed on the first shell 13 and on the periphery of the output shaft 11 of the motor 10; the cylinder shaft 21 passes through the second housing 23 and is connected to the second transmission wheel 22, and a second reinforcing rib (not shown) is formed on the second housing 23 around the cylinder shaft 21 to ensure the strength of the first housing 13 and the second housing 23.
