Technical Field

[0001] The utility model relates to the field of oral irrigators, in particular to an oral irrigator with a high-pressure self-lubricating Y-shaped sealing ring structure. Background Art

[0002] A water flosser is an electric device used to clean the oral cavity, also known as an oral irrigator or water flosser. It removes food debris and bacteria between teeth by spraying high-pressure water or water pulses to achieve the effect of deep cleaning of the oral cavity. The pump inside the water flosser needs to use a piston when delivering water, and a sealing ring is needed to maintain the sealing between the piston and the cylinder wall. Therefore, a water flosser with a high-pressure self-lubricating Y-shaped sealing ring structure is proposed.

[0003] Most of the sealing rings used in existing oral irrigators are made of pure rubber. Due to the large friction coefficient between the sealing lip and the moving shaft, the friction temperature increases, causing the sealing lip to age and become non-wear-resistant, resulting in poor sealing effect and easy wear. Therefore, it is difficult for the sealing ring to withstand millions of reciprocating motions, resulting in water seepage around the piston, which may reduce the service life of the oral irrigator. For this reason, technical improvements are urgently needed. Utility Model Content
