Usually, it consists of a bowl-shaped rubber head and a wooden rod-shaped handle embedded in it. Before use, the hair at the floor drain and grate should be cleaned up. When cleaning the pool, if possible, it is best to block the overflow of the pool with a wet cloth. Press the bowl-shaped rubber head on the sewer mouth, or press it down continuously, so that air is pressed into the pipeline, or press it down hard, and when the rubber head is flattened, it will pull back quickly, resulting in a vacuum state. The purpose is to loosen or disperse the blockage in the sewer pipe.
Usage: add water to the toilet. When the amount of water can have a certain impulse, kick the skin at the mouth of the toilet and press it fiercely. As long as you hear it, it makes it clear. If not, add water and press it again.
The toilet plunger may have been invented between 1850 and 1900, when the technology of practical wood and synthetic rubber was very popular. The strong evidence to support this statement is that the rubber sucker was invented in the 1950s in 19. Therefore, the invention time of modern toilet plunger is at least after 1850.
In addition, the toilet plunger works with the S-type drain pipe, which first appeared in 1852.
