Skin care device for taking out and removing sebum or other cutaneous impurities
View Patent ↗A skin care device includes a suction nozzle to be brought into contact with skin to suction skin impurities therefrom, a suction pump for generating a suction force of the suction nozzle, a mist nozzle installed near the suction nozzle, for ejecting a mist of liquid, a tank for storing therein a liquid to be supplied to the mist nozzle, a liquid supply pump for supplying the liquid to the mist nozzle from the tank, a drive motor for driving the suction pump and the liquid supply pump at the same time, and a liquid amount control unit for controlling an amount of the liquid ejected from the mist nozzle. The liquid amount control unit is a flow rate regulation device disposed between the tank and the mist nozzle.
1. A skin care device comprising:
a suction nozzle to be brought into contact with skin to suction sebum or other impurities therefrom;
a suction pump for generating a suction force of the suction nozzle;
a mist nozzle installed near the suction nozzle, for ejecting a mist of liquid;
a tank for storing therein a liquid to be supplied to the mist nozzle;
a liquid supply pump for supplying the liquid to the mist nozzle from the tank;
a drive motor for driving the suction pump and the liquid supply pump at the same time; and
a liquid amount control unit for controlling an amount of the liquid ejected from the mist nozzle,
wherein the suction pump and the liquid supply pump face each other with a rotating shaft interposed therebetween, the rotating shaft being provided on the drive motor.
2. The device of claim 1 , wherein the liquid amount control unit is a flow rate regulation device disposed between the tank and the mist nozzle.
3. The device of claim 2 , wherein the flow rate regulation device includes a pipe formed at a conduit connected between the tank and the mist nozzle, the pipe having a cross sectional area smaller than that of the conduit.
4. The device of claim 2 , wherein the flow rate regulation device is detachable from the skin care device, the flow rate regulation device being of a cartridge type.
5. The device of claim 2 , wherein the flow rate regulation device is formed of a resilient tube.
6. The device of claim 2 , wherein the flow rate regulation device includes a tube and a contact member to be brought into contact with the tube to change a cross sectional area of the tube.
7. The device of claim 5 , wherein the tube is disposed on outer peripheral portions of the suction pump and the liquid supply pump in a spiral shape.
8. The device of claim 2 , wherein the flow rate regulation device is a pin projected into a conduit connected between the tank and the mist nozzle and a projecting amount of the pin is controllable from the outside of a housing of the skin care device.
9. The device of claim 2 , wherein the flow rate regulation device is a liquid storage disposed in a conduit connected between the tank and the mist nozzle and an inner volume of the liquid storage is controllable from the outside of a housing of the skin care device.
10. The device of claim 2 , wherein a heater is installed near a conduit connected between the tank and the mist nozzle.
11. The device of claim 2 , wherein a heater is installed inside the tank.
12. The device of claim 2 , wherein the mist nozzle is provided with a plurality of mist ejection holes oriented in different ejecting directions, respectively.
13. The device of claim 2 , further comprising a mist ejection angle control device for controlling a mist ejection angle of the mist nozzle.
14. The device of claim 2 , wherein the ejection amount of the liquid ranges from about 0.2 ml/mm to about 0.7 ml/mm.
