[0019] The first embodiment of the present application is:

[0020] See also Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of a motor rotor housing of a back scrubbing machine according to the first embodiment of the utility model. Figure 2 It is a schematic structural diagram of the outer shell, the top shell and the bottom shell of the first embodiment of the utility model.
