The use of multiple materials enables the baffle to adapt to different scenarios.
Furthermore, an arc-shaped flow passage is arranged on the water distribution flow passage, a through hole is formed in the middle of the arc-shaped flow passage, and the arc-shaped flow passage is divided into two different flow passages. The setting of arc runner makes liquid flow more smoothly, and the setting up of through-hole makes upper and lower floor flow more smooth and easy.
Furthermore, the two different flow channels are divided into an upper concave flow channel and a lower concave flow channel, and the upper concave flow channel and the lower concave flow channel are respectively arranged on the lower surface and the upper surface of the water distribution flow channel. The arrangement of the double-sided flow channel enables the liquid to smoothly flow on any side.
Different from the prior art, the technical scheme has the following beneficial effects:
the utility model discloses the baffle design is three-layer crowded material layer altogether, including skin, intermediate level and inlayer, when stacking the baffle, skin and inlayer between the adjacent baffle will laminate mutually and directly form an antiseep circle, need not remove in addition and tailor a frame, adhere to and act as one deck antiseep layer on the frame of baffle, perhaps directly scribble one deck antiseep coating on the frame of baffle, reduce the technology degree of difficulty and cost, make things convenient for material recycle, resources are saved.
