Abstract
A method of enhancing the negative pressure of siphon of toilet is to suck the air between the two traps to enhance the negative pressure between the two seal-water, so as to rapidly form a siphon in the traps and flush the waste out rapidly. A suction device for enhancing the negative pressure of siphon of a toilet is used. It comprises: a water container installed in the water tank, said water container is provided with a water inlet and outlet; an air container with an opening in the bottom installed inside the water container, the lower portion of the side wall of the air container has a water opening connected to the water container; and a connecting tube, the bottom of which is connected to the trapway of the toilet, and the top is connected to the top of the air container.
