Water pick structure and design method of water outlet hole in water pick structure

Abstract

The invention provides an oral irrigator structure and a design method of a water outlet hole in the oral irrigator structure, the oral irrigator structure comprises a lower shell with a water inlet channel and an upper shell covering the lower shell, a sliding piece capable of sliding in the length direction is arranged between the upper shell and the lower shell, an insert is arranged at the front end of the upper shell, and a water outlet hole is formed in the insert. Water outlet holes are densely distributed in the insert, a hole sealing pad with hollowed-out holes is arranged at the front end of the sliding piece, the hollowed-out holes correspond to the water outlet holes, and the hollowed-out holes are communicated with the water outlet holes, so that high-pressure water entering the water inlet channel is sprayed out after passing through the hollowed-out holes and the water outlet holes. By moving the sliding piece to different positions, the water outlet of the spray head can have three states: single-water-column water outlet, small-amount-water-column water outlet, multi-water-column water outlet and the like; by means of the structure, different water outlet states of the spray head are achieved, and different use requirements are met.

Description

Technical field: [0001] The invention relates to the technical field of oral cleaning devices, in particular to a dental flosser structure and a design method for an upper water outlet hole. Background technique: [0002] The toothbrush is simple and convenient, and has a good cleaning effect on the tooth surface that can be reached. Dental floss (including toothpicks commonly used by Chinese people) has a good effect on cleaning foreign objects clamped between the teeth and part of the gingival sulcus; dental flossers In the past, it has been used as an auxiliary tool for toothbrushes. The high-speed water flow of the dental flosser has its unique cleaning and health care functions and is easy to use. It is designed as a single water column with a limited amount of water to flush between teeth and gingival sulcus and other places where toothbrushes are not easy to clean; but single water column Flossers have fatal flaws, just like showering directly with the faucet, which c...

The high-speed water flow of the dental flosser has its unique cleaning and health care functions and is easy to use. It is designed as a single water column with a limited amount of water to flush between teeth and gingival sulcus and other places where toothbrushes are not easy to clean; but single water column Tooth flossers have fatal flaws, just like showering directly with the faucet, which cannot rinse the body quickly and effectively. At the same time, a single water jet is very strong at a single point, and it is easy to cause damage to the gums.
