Technical field

The present invention relates to Oral cleaner more particularly to a kind of waterproof seal and stamping machines.

Background technique

Stamping machine is a kind of household mouth washes equipment.Its principle is to remove dispel plaque and gum using the pulsating water of flowing Remaining food below line, so as to improve oral health.It include electric component and water pump component in stamping machine machine, because of water pump group Piston is moving component in part, is easy to cause water and other fluids to leak out in the case where poor sealing effect out of pumping cylinder, such as takes Improper measures, leak is easy to encounter electronic component, scraps stamping machine failure even.

The water pump of current portable stamping machine mostly uses reciprocating piston structure, usually installs in the peripheral surface of piston The sealing ring of standard specification is inevitably worn between piston and piston cavity wall to reach sealing effect, especially It is the swing that piston drive bar can also generate certain amplitude under the driving of eccentric wheel, so that sealing ring stress is more greatly, more It is prone to wear, is easy leakage using water pump after a period of time, stamping machine failure is caused even to be scrapped.

Summary of the invention
