Abstract

An oral irrigator includes: an irrigator body, and a generator arranged inside the irrigator body. The irrigator body includes: a water tank, a nozzle, and a driver. The water tank is used to accommodate an electrolyte. The generator is used to electrolyze the electrolyte to generate ozone water and hydrogen-rich water. The electrolyte of the water tank is driven by the driver to enter the generator, electrolyzed in the generator, such that a resulting electrolyzed ozone water and hydrogen-rich water are sprayed out from the nozzle of the irrigator body. In this way, it is solved the technical problem that the existing oral irrigator only uses a water flow for physical cleaning.

Claims (45)

1. An oral irrigator, comprising:

an irrigator body, comprising: a water tank, a nozzle, and a driver; and

a generator, arranged inside the irrigator body; and

wherein

the water tank is configured to accommodate an electrolyte;

the generator is configured to electrolyze the electrolyte to generate ozone water and hydrogen-rich water; and

the electrolyte of the water tank is driven by the driver to enter the generator, electrolyzed in the generator to generate the ozone water and the hydrogen-rich water, such that the electrolyzed ozone water and the hydrogen-rich water are sprayed out from the nozzle of the irrigator body;

the driver comprises: a pump and a motor adapted to the pump; and

the generator is arranged between the water tank and the pump, a water inlet communicates with the water tank, and a water outlet communicates with an inlet of the pump, the generator is assembled at a top of the water tank, the water inlet of the generator is provided with a connecting pipe, and the connecting pipe is arranged within the water tank.

2. The oral irrigator of claim 1 , wherein

the electrolyte is water;

the generator comprises: at least one cathode plate, at least one anode plate, and a casing enclosing the at least one cathode plate and the at least one anode plate; the at least one cathode plate and the at least one anode plate are spaced apart from one another and arranged alternately; and

the at least one cathode plate and the at least one anode plate are in electrical connection with a negative electrode and a positive electrode of a power source assembly of the irrigator body, respectively; and

the casing is provided with a water inlet and a water outlet.

3. The oral irrigator of claim 2 , wherein a number of the at least one cathode plate is two, and a number of the at least one anode plate is one; and the one anode plate is arranged between the two cathode plates.

4. The oral irrigator of claim 2 , wherein a distance between the at least one cathode plate and the at least one anode plate is smaller than or equal to 5 mm.

5. The oral irrigator of claim 2 , wherein an area of each of the at least one cathode plate and the at least one anode plate is smaller than or equal to 20 square centimeters.

6. The oral irrigator of claim 2 , wherein both of the at least one cathode plate and the at least one anode plate are made of a titanium alloy.

7. The oral irrigator of claim 2 , wherein

the generator further comprises an assembling body;

the assembling body and the casing form an integrated structure; and

the assembling body is arranged at the top of the water tank, and is configured to assemble the pump and the motor.

8. The oral irrigator of claim 7 , wherein

the assembling body defines therein an assembling recess;

the pump and the motor are in connection with assembling pieces; and

the assembling pieces are arranged within the assembling recess to connect the pump, the motor, and the water tank to be another integrated structure; and

a housing is sleeved outside the pump and the motor.

9. The oral irrigator of claim 8 , wherein a number of the at least one cathode plate is two, and a number of the at least one anode plate is one; and the one anode plate is arranged between the two cathode plates.

10. The oral irrigator of claim 8 , wherein a distance between the at least one cathode plate and the at least one anode plate is smaller than or equal to 5 mm.

11. The oral irrigator of claim 8 , wherein an area of each the at least one cathode plate and the at least one anode plate is smaller than or equal to 20 square centimeters.

12. The oral irrigator of claim 8 , wherein both of the at least one cathode plate and the at least one anode plate are made of a titanium alloy.

13. The oral irrigator of claim 8 , wherein

a number of the at least one cathode plate is two, and a number of the at least one anode plate is one; and the one anode plate is arranged between the two cathode plates;

a distance between the at least one cathode plate and the at least one anode plate is smaller than or equal to 5 mm;

an area of each of the at least one cathode plate and the at least one anode plate is smaller than or equal to 20 square centimeters; and

both of the at least one cathode plate and the at least one anode plate are made of a titanium alloy.

14. The oral irrigator of claim 1 , wherein

the generator further comprises an assembling body;

the assembling body and a casing of the generator form an integrated structure; and

the assembling body is arranged at the top of the water tank, and is configured to assemble the pump and the motor.

15. The oral irrigator of claim 14 , wherein

the assembling body defines therein an assembling recess;

the pump and the motor are in connection with assembling pieces; and

the assembling pieces are arranged within the assembling recess to connect the pump, the motor, and the water tank to be another integrated structure; and

a housing is sleeved outside the pump and the motor.
