The invention belongs to the technical field of tooth cleaning equipment, and particularly relates to a device for controlling a volume ratio of water to air injected by
oral irrigator based on tartar
colored patches. The device comprises a high-pressure air storage
bottle, a
water storage bottle, a
nozzle and a protective shell, the high-pressure air storage
bottle and the
water storage bottle are arranged in the protective shell, the
nozzle is arranged outside the protective shell, the high-pressure air storage bottle is communicated to the
water storage bottle through a communicating
pipe, the water storage bottle is communicated to the
nozzle through a water conveying
pipe, a one-way valve is arranged on the communicating
pipe, and a water valve is arranged on the water conveying pipe; the high-pressure air storage bottle is communicated to a water valve-front water conveying pipe through an air conveying pipe, and an air valve is arranged on the air conveying pipe; a
data acquisition module is arranged for acquiring morbidity of the tartar
colored patches and residue data in real time, a analyzing and
processing module is arranged for analyzing and
processing the morbidity of the tartar
colored patches and the residue data, and a control module is arranged for controlling the water valve and the air valve in real time according to the analyzed and processed data; and the volume ratio of water to air of the water flosser can be controlled in real time to clean the teeth according to the actual situation of the tartar colored patches or residues in teeth.
