Abstract:
1. A faucet with temperature control function having a replaceable handle comprising a main valve body, a first decorative cap, a conversion sleeve, an indication ring, a conversion rod, a second decorative cap and a handle; wherein a valve tube of predetermined diameter is extended across a bottom terminal of the main valve body, wherein a flow passage passes; the valve tube is perpendicular to the main valve body; a longitudinal spindle extends from a front end of the main valve body; a top end of the spindle is extended with a water control knob, which is in turn provided with annularly arranged teeth for the engagement with a foreign control device; the first decorative cap is a hollow cylinder, an inner wall of which is provided with three stepped walls; a middle one of the three stepped walls is provided with an inner screw thread for engagement with an outer screw thread on an outer wall of the main valve body, as the first decorative cap is being mounted onto the main valve body; an upper one of the walls has a smallest inner diameter designed for being attached on a corresponding part of the main valve body; a conversion mechanism includes a conversion sleeve and a conversion rod; the conversion sleeve is a hollow ring body capable of being engaged with the main valve body in the longitudinal direction; an inner wall of the conversion sleeve forms a gradually expended stepwise block surface for connecting an indication ring; a central part of the top end of the conversion sleeve is extended, both inwardly and outwardly, with a connection section, the connection portion further comprises an inwardly extended section and an outwardly extended section; there is a passage going through an axes of the outwardly extended section and the inwardly extended section; the axial passage is further provided with a connecting section with parallel teeth to the water control knob, whereby the conversion sleeve and the main valve body are mutually connected; an inner wall of the outwardly extended section is proved with an inner screw thread, whereas an outer wall of the inwardly extended section is provided with an outer screw thread, respectively for engaging the conversion rod and the first decorative cap; the indication ring is a hollow ring body with a stepwise inner wall has a first annular surface on a top thereof for a connection between the indication ring and the conversion sleeve, whereby the conversion sleeve and the indication ring will rotate synchronically; a top surface of a next section of the indication ring around the first annular surface forms a second annular surface; the conversion rod is a cylindrical rod and has an outer screw thread at a bottom end thereof for connecting the conversion sleeve; a top end of the conversion rod is provided with a connection knob which is a section of parallel teeth; the second decorative cap is a cap body with a tapered outer shape and a stepwise inner wall; an inner wall of the second decorative cap is provided with an inner screw thread for engagement with the outwardly extended section from the conversion sleeve; further, the conversion rod passes through the second decorative cap and is locked with the outwardly extended section, and the connection knob at the top end of the conversion rod is extended out of the second decorative cap, whereby the second decorative cap will cover most of the conversion rod; and the handle is used for driving the water control valve so as to adjust water flow rate; the handle comprises a connecting section having an inner wall provided with a section of parallel teeth for engaging a corresponding section of parallel teeth of the connection knob, whereby the handle and the conversion rod are rotationally connected and can move synchronically.
