The teeth were rinsed with diluted mouthwash. There are many brands of mouthwashes on the market, and the ingredients of each family of mouthwashes vary greatly. The mouthwash has the function of cleaning the oral cavity, but simultaneously, the mouthwash has an influence on the service life of the table type tooth flusher. The reason is that inside the table type tooth flushing device, a piston is used for pushing water flow, and in order to enable the water flow pushed by the piston to be smoother. Food grade lubricating oil is often required on the piston to reduce friction with other structures as the piston pushes water. After the user added the water tank with the mouthwash, some compositions of mouthwash can erode the lubricating oil on the piston, made the lubricating oil on the piston reduce, caused the motion resistance increase of piston, the kinetic energy loss of piston will aggravate.
