1. A rationed water outlet device with a variable water flow volume, comprising: a process control module that communicates with the water source and that comprises an outlet valve, a flow meter, a control chip, and an encoder that includes an unlimited outlet gear and a plurality of rationed outlet gears which are switchably connected to the outlet valve to provide respectively, when engaged, an unlimited water flow volume or a selected rationed water flow volume from among a plurality of rationed water flow volumes, and that is connected to the control chip to provide gear selection information;a volume option switch that is rotatably linked to the encoder for engaging the unlimited outlet gear or one rationed outlet gear of the plurality of rationed outlet gears for a user to select the unlimited water flow volume or the selected rationed water flow volume; andan outlet control switch that is independent of the volume option switch and that is engaged after the volume option switch is engaged. 2. The rationed water outlet device according to claim 1, wherein the rationed water outlet device includes an outlet portion provided with a marker, and wherein the volume option switch is a rotating ring disposed at one side of the outlet portion of the rationed water outlet device and disposed with a volume dividing ruler to facilitate volume selection by alignment with the marker. 3. The rationed water outlet device according to claim 2, wherein, when the volume option switch rotates to one side, the encoder rotates to the unlimited outlet gear; and, when the volume option switch rotates to another side, the encoder rotates to one rationed outlet gear of the plurality of rationed outlet gears. 4. The rationed water outlet device according to claim 2, wherein the volume dividing ruler of the rotating ring of the volume option switch is disposed with a scale corresponding to the unlimited outlet gear and a plurality of scales corresponding to respective ones of the plurality of rationed outlet gears so that, when the rotating ring rotates to make one of the scales align with the marker of the outlet portion of the rationed water outlet device, a corresponding outlet gear is selected. 5. The rationed water outlet device according to claim 1, wherein the outlet control switch comprises a touch induction switch so that, when the encoder is disposed in one rationed outlet gear of the plurality of rationed outlet gears, the outlet valve of the process control module is opened by touching the touch induction switch and, at the same time, the flow meter of the process control module starts to count and, when the flow volume reaches a set value of said one rationed outlet gear, the control chip of the process control module controls the outlet valve of the process control module to turn off water flow from the rationed water outlet device. 6. The rationed water outlet device according to claim 5, wherein the outlet control switch further comprises a temperature control device. 7. The rationed water outlet device according to claim 6, wherein the temperature control device is a dial rod and the touch induction switch has a touch area that is disposed in the dial rod, and wherein the control chip receives cool water and hot water from the water source and adjusts a mixing proportion of the cool water and the hot water by adjusting the position of the dial rod so as to control outlet temperature of the water flowing out of the rationed water outlet device. 8. The rationed water outlet device according to claim 7, wherein, when the encoder is situated in the unlimited outlet gear, the touch induction switch is inoperative and the outlet valve of the process control module is turned on by rotating the dial rod, and the outlet temperature becomes higher by continuously rotating the dial rod. 9. The rationed water outlet device according to claim 6, wherein a temperature indication unit and a temperature sensor are further provided so that, when the outlet temperature becomes higher, color of the temperature indication unit gradually transitions from blue to red. 10. The rationed water outlet device according to claim 5, wherein the outlet control switch further comprises a mechanical outlet switch so that, when the encoder is situated in the unlimited outlet gear, the touch induction switch and the proceed control module are respectively inoperative and outlet flow volume and outlet temperature are adjusted by operating the mechanical outlet switch. 11. The rationed water outlet device according to claim 10, wherein the rationed water outlet device is disposed with an induction window, and wherein the induction switch is disposed at a position in the rationed water outlet device corresponding to the induction window. 12. The rationed water outlet device according to claim 1, wherein the rationed water outlet device is a kitchen tap or a shower head.
