[0007] A control module installation groove is arranged on the inner shell, and a silk screen panel is arranged on the inner shell at a position corresponding to the control module installation groove.

[0008] A battery assembly groove is arranged on the back of the rear cover, one side of the rear cover is provided with a charging terminal assembly groove, and a water pump water inlet and outlet connector accommodation hole is further arranged on the rear cover.

[0009] A charging jack is arranged on the shell at a position corresponding to the charging terminal assembly groove.

[0010] Preferably, the control module mounting groove and the position opposite to the inner wall of the rear cover of the inner shell are provided with reinforced studs.

[0011] Preferably, the back of the inner shell is provided with waterproof O-rings.

[0012] Preferably, the inner walls of the control module mounting groove, the battery assembly groove and the charging terminal assembly groove are provided with wire holes.

[0013] Preferably, the bottom of the outer shell is provided with a foot pad.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The utility model discloses a split type outer shell, inner shell and rear cover structure, and the control module mounting groove, battery assembly groove and charging terminal assembly groove adopt independent installation mode to control module, battery and charging terminal, and the isolation effect of water seepage and water vapor is better, and the influence of rust and short circuit is reduced.
