On the other side of the bottom plate 7 with respect to the support plate 10, a connection block 8 is provided, the connection block 8 extending from the bottom of the bottom plate 7 up through the bottom plate 7 to the top of the bottom plate 7.

Two tee-joint channels are arranged in the connecting block 8 side by side, and the two tee-joint channels in the connecting block 8 are respectively a liquid inlet channel and a liquid outlet channel. One of the inlet channel and the outlet channel extends to the upper surface of the bottom plate 7 along with the connecting block 8, the other two channels are positioned at two sides of the connecting block 8 below the bottom plate 7, and the channel positioned below the bottom plate 7 is used as a port 9 to be connected with the connecting hose 3.
