Description

Technical Field

[0001] The utility model relates to a dental flosser. Background Art

[0002] Oral irrigators are generally used for oral care and are oral cleaning and health care appliances. They mainly use high-speed water flow to rinse teeth to achieve the effect of cleaning teeth. At present, most oral irrigators on the market hide the spray rod in the storage cavity of the shell. When using, the spray rod is taken out and installed at the water outlet. After use, the spray rod is removed and put back into the storage cavity. The spray rod needs to be disassembled and assembled every time it is used, which is cumbersome. At the same time, multiple disassembly and assembly can easily cause damage to the connection of the spray rod, resulting in poor sealing, resulting in the inability to form high-speed water, which greatly reduces the service life of the oral irrigator.

The nozzle is provided with a second water inlet and a high-speed water outlet. The second water inlet is rotatably or fixedly connected to the first water outlet. When the rotatable connection is set, the nozzle can rotate around the axis of the first water outlet. The shell is telescopically slidably arranged on the outside of the main body, and the telescopic sliding direction is perpendicular to the rotation axis of the rotating body. When the shell is fully retracted and the nozzle is in the recessed part, the shell can cover the outside of the nozzle to protect the nozzle and block dust, such as placing it upside down. The front of the main body is L-shaped due to the recessed part. The end close to the rotating body is the small end, and the end close to the shell is the large end. The main body is provided with a water inlet pipe and a pumping mechanism. The water in the shell is powered by the pumping mechanism, and is sprayed out from the high-speed water outlet at high speed after passing through the water inlet pipe.
