As a kind of optimal way, the outer wall of described shell is provided with horizontally disposed annular backup pad, the outer end of annular backup pad is vertically arranged with annular sidewall, annular backup pad, annular sidewall and described shell surround annular groove jointly, described first sealing ring is embedded in annular groove, the outer wall of the lower end of described end cap is provided with ring buckle plywood, the lower end of ring buckle plywood is to having annular lug, annular lug is embedded in annular groove and the lower end of annular lug is supported on described first sealing ring, the lower surface of ring buckle plywood all abuts with the upper surface of the upper surface of shell and annular sidewall.
As a kind of optimal way, the medial wall of described end cap is provided with the collar flange that the inner side towards described end cap extends, described string holes is located in collar flange, described wire stretches out in collar flange, the inner wall sleeve of described second sealing ring is located on the outer wall of described wire, and the outer wall of described second sealing ring is supported on the inwall of collar flange.
In such scheme, described end cap is screwed on described shell.
It is preferred that be provided with EVA pad between the bottom of the bottom of described accumulator and described shell.
After adopting technical scheme, prevent water from passing through between end cap and shell by the first sealing ring, prevent water from penetrating between wire and end cap by the second sealing ring, play good sealing effectiveness, end cap is detachably connected on shell simultaneously, conveniently internal storage battery parts is overhauled.

Detailed description of the invention
In order to technical scheme is explained further, it is described in detail below in conjunction with accompanying drawing.
Referring to figs. 1 through Fig. 3, a kind of enclosed cell water pump, including water pump body (not shown) and the accumulator cell assembly in order to water pump body is powered, connected by external wire 30 between water pump body and accumulator cell assembly, water pump body is existing in the prior art to be introduced, and is no longer described in detail here.Heretofore described accumulator cell assembly includes shell 10, accumulator 60, PCB 80 and the end cap 20 in order to closure 10, accumulator 60 and PCB 80 and is contained in shell 10, and end cap 20 is removably attachable on shell 10.It is provided with EVA pad 70, to protect accumulator 60 better between the bottom and the bottom of described shell 10 of described accumulator 60.Described wire 30 one end is connected in PCB 80, and the other end passes from the string holes 24 sidewall being arranged on end cap 20, and is connected on water pump body.Present invention additionally comprises the first sealing ring 40 being arranged between described end cap 20 and described shell 10 and in order to seal the second sealing ring 50 of described string holes 24.
A kind of optimal way as the present invention, the outer wall of described shell 10 is provided with horizontally disposed annular backup pad 11, the outer end of annular backup pad 11 is provided with annular sidewall 12 straight up, annular backup pad 11, annular sidewall 12 and described shell 10 surround annular groove 13 jointly, and described first sealing ring 40 is embedded in annular groove 13.The outer wall of the lower end of described end cap 20 is provided with ring buckle plywood 21, the lower end of ring buckle plywood 21 is to having annular lug 22, annular lug 22 is embedded in annular groove 13 and the lower end of annular lug 22 is supported on described first sealing ring 40, and the lower surface of ring buckle plywood 21 all abuts with the upper surface of shell 10 and the upper surface of annular sidewall 12.So, by setting up annular sidewall 12 and annular groove 13, coordinate the first sealing ring 40 in annular groove 13, it is ensured that sealing property good between end cap 20 and shell 10.
