Shower fragrance enhancer, the product does not need to be powered on. It is connected to a handheld showerhead faucet, with upper and lower outlets. The inlet is equipped with a union nut, and the lower outlet has a 4-point outer tooth. The working principle is that the water passes through the liquid pipe, and then makes a three-way connection. The yellow part is the liquid to bring out the ball, and there is a water balloon in it. When the water is opened, the balloon expands to extrude the perfume in the liquid outlet ball, mixes it into the blue water pipe through a small pipe, and then flows out through a flower shower. And to achieve automatic flow of liquid from the showerhead without the need for manual pressing, the size of the liquid can be manually adjusted.
