An installing structure of the device used in the digital shower system as claimed in claim 11 further comprising a closing means, wherein waterproof sealing glue is applied between the first abutting portion of the controlling panel and the external face of the front fence to generate a) waterproof sealing structure.

13. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein the housing includes a removable cover, and the cover corresponds to the back side of the controlling panel via the groove.

14. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein the retaining means includes two bolts, two bores mounted on the controlling panel, and two orifices disposed on a cover of the housing so as to correspond to the two bores, and the first abutting portion of the controlling panel is biased against the external face of the front fence by inserting the two bolts through the two bores to screw with the two orifices.

15. An installing structure of the device used in the digital shower system as claimed in claim 14, wherein the controlling panel further includes a removable adjusting knob to cover the two bores.

16. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein the controlling panel is fitted into the valve box to form an anti-rotating structure.

17. An installing structure of the device used in the digital shower system as claimed in claim 16, wherein the anti-rotating structure includes a non-circular first cliff arranged on a side fringe connected with a peripheral side of housing, and a non-circular second cliff formed on an outer surface of a positioning rim of the controlling panel, and when the first abutting portion of the controlling panel contacts with the external face of the front fence, the groove engages with the first cliff of the side fringe of the housing to form the anti-rotating structure, thus preventing the controlling panel from rotation, and the second cliff slides in the first cliff.

18. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein the fixing plate includes a pressing portion and an outer peripheral segment integrally extending from the pressing portion; the pressing portion includes the second abutting portion fixed around a back side thereof, and the outer peripheral segment includes two symmetrical resilient locking members and two defining slots arranged therein to receive the engaging blocks; the body includes a flat portion and an inner peripheral segment integrally extending from an inner surface of the flat portion; the inner peripheral segment includes two symmetrical recesses secured on an outer side thereof to engage with the resilient locking members, and when the flat portion is connected to the fixing plate, it covers the pressing portion of the fixing plate and the bores.

19. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein a removable wire is electrically connected between the controlling panel and the valve box, and includes a power line and a control line, the wire is long enough to remove the controlling panel from the groove so that the valve box is cleaned, checked, and repaired via the groove.

20. An installing structure of the device used in the digital shower system as claimed in claim 11, wherein the controlling panel allows to control the valve box in a wireless manner.
