In order that the purpose of this utility model, technical scheme and Advantageous Effects become apparent from understanding, below in conjunction with
Accompanying drawing in this utility model embodiment, is clearly and completely retouched to the technical scheme in this utility model embodiment
State, it is clear that described embodiment is only a part of embodiment of this utility model, rather than the embodiment of whole.
Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
Every other embodiment, belong to this utility model protection scope.
As shown in Fig. 1 and Fig. 4, a kind of electrokinetic cell module bottom surface protection structure 100 that this utility model is provided, including suction
Modeling box 10, support 20, cylinder manifold 30, collection plate 40 and the multiple cells 50 being contained in support 20.
Fig. 2 to Fig. 4 is referred to, the vacuum formed box 10 is made up of plastics Jing moulding processs.The vacuum formed box 10 includes diapire
11st, the side wall 12 for being formed is upwardly extended by the edge of diapire 11.The diapire 11 surrounds cavity 13 jointly with side wall 12.The side wall
12 one end opens.In present embodiment, the diapire 11 is substantially rectangular.
The support 20 includes the lower surface 22 opposite with the upper surface 21 of upper surface 21 and is connected to the upper surface
