Intelligent function of oral irrigator and detection algorithm of intelligent function

Abstract

The invention provides an intelligent function of an oral irrigator and a detection algorithm of the intelligent function. The oral irrigator comprises an electric quantity detection circuit, a CPU master controller, a motor detection circuit and a motor. The motor detection circuit is used for detecting the running state of the motor and feeding back the running state to the CPU master controller; and the electric quantity detection circuit is used for sending acquired electric quantity information to the CPU master controller. In the invention, when it detects that a water tank is empty, water stops; when it detects that a motor gear is jammed or a nozzle is blocked by foreign matters, water stops automatically, and a user is reminded; and when it detects that power failure is caused dueto the fact that a motor needs large current during working, water stops ahead of time. When the motor just runs, water outlet intensity is slowly increased according to time, an anti-splashing function is fulfilled, and the experience effect of the oral irrigator is improved.

Description

technical field [0001] The invention relates to an intelligent function of a dental flosser and related algorithms, in particular to an algorithm for detecting and judging circuit device states such as motor working state, battery discharge state and related level states. Background technique [0002] The control of the water outlet on the existing common dental flossers is basically a timed shutdown, or the user is required to manually stop the water outlet. Although this kind of control is simple and easy to implement, it will continue to consume power when the water tank is running out of water, which wastes battery power and reduces the use time; it is not necessary for gears to be stuck abnormally or nozzles to be blocked by foreign objects. It cannot be detected, and when the motor is stuck or blocked by foreign objects, but the motor is running normally, this will not only cause the battery power to drop rapidly but also cause the motor to be scrapped, or the battery ...

Although this kind of control is simple and easy to implement, it will continue to consume power when the water tank is running out of water, which wastes battery power and reduces the use time; it is not necessary for gears to be stuck abnormally or nozzles to be blocked by foreign objects. It cannot be detected, and when the motor is running normally when it is stuck or blocked by foreign objects, this will not only cause the battery power to drop rapidly but also cause the motor to be scrapped, or the battery is over-discharged
