Technical Field

The invention relates to the technical field of tooth washing devices, in particular to a water mist generating structure of a tooth cleaner.

Background

The existing tooth cleaner using water mist to clean teeth in the market has the principle that when liquid is contacted with air flow, high-speed air flow acts on the liquid to force the liquid to be sprayed out from a nozzle to form water mist; the high velocity gas stream is derived from a compressed gas such as a cartridge to provide the energy required for the gas stream; the air source of the containing cylinder has the limitation of safety, needs to be replaced frequently, and is inconvenient to use and not environment-friendly.

Chinese patent CN102271661B discloses a non-pressurized system for generating droplets in a prophy gear comprising a prophy gear having a body portion and a nozzle portion, a liquid reservoir and a system for driving a plunger or piston element towards the proximal end of the nozzle with sufficient force such that air acted upon by the plunger or piston element is driven or released into the nozzle portion at a high rate sufficient to produce a droplet spray when moving air comes into contact with the liquid. Liquid in the liquid reservoir is moved by a pump or suction to the vicinity of the orifice and the drive gear has an open space such that when the open space is adjacent the plunger or rack and pinion on the piston, the disengagement connection releases the plunger, driving the plunger under the action of the compression spring to release at high speed towards the orifice, thereby driving air in the chamber through the orifice. The non-pressurized system for generating liquid drops replaces a gas source structure of a containing cylinder, so that replacement and safety limitation are avoided, but two mechanisms of liquid conveying and gas conveying need to operate synchronously, the atomization generation effect is limited by the specification of a nozzle, a liquid spraying mode or a gas spraying mode cannot be independently used, and the output quantity cannot be adjusted.
