Description
BACKGROUND OF THE INVENTION
Field of the Invention

The present invention relates to a showerhead structure which has aesthetics appearance and is machined easily.


Description of the Prior Art

Shower equipment contains a fixed showerhead and a manual showerhead, wherein the fixed showerhead is mounted on a wall and is in connection with a water pipe so that water flows into the fixed showerhead and then sprays out of spray nozzles of the fixed showerhead downwardly, thus taking a shower. This fixed showerhead is assembled easily and securely, but its size and aesthetics appearance cannot be improved greatly.


With reference to FIGS. 12-14, a fixed showerhead structure contains a case 10, a water supply cover 20, a water disc 30, a locking disc 40, and an outflow disc 50.


The case 10 includes a fitting orifice 101 defined on a top thereof, the water supply cover 20 is in a circular disk shape and includes a peripheral rib 201 arranged around a rim of the water supply cover 20, and the peripheral rib 201 has multiple fixing orifices 2011 equidistantly defined thereon so as to accommodate multiple screws 2012 respectively. The water disc 30 includes a stop rib 301 arranged around a rim thereof, includes multiple outlets 302 formed on the water disc 30, and multiple hollow columns 3021 extending downward from bottoms of the multiple outlets 302 individually. The locking disc 40 includes a protruded rib 401 arranged around a rim of a top thereof, multiple notches 402 equidistantly defined around the top of the protruded rib 401 outside the rim of the top of the locking disc 40, and multiple through holes 403 formed inside the protruded rib 401 and corresponding to the multiple hollow columns 3021 of the water disc 30 individually. The outflow disc 50 includes multiple orifices 501 corresponding to the through holes 403 of the locking disc 40 respectively, and multiple hollow spray protrusions 502 extending through the multiple orifices 501 of the outflow disc 50 and the multiple through holes 403 of the locking disc 40 respectively, wherein the multiple hollow columns 3021 of the water disc 30 insert into the multiple hollow spray protrusions 502 of the outflow disc 50 respectively.


In assembly, the locking disc 40 is stacked on the outflow disc 50 so that the multiple hollow spray protrusions 502 are upward extended through the multiple orifices 501 of the outflow disc 50 and the multiple through holes 403 of the locking disc 40 respectively, and the multiple hollow spray protrusions 502 are riveted on the locking disc 40, such that the locking disc 40 is connected with the outflow disc 50. The water disc 30 is stacked on the locking disc 40 so that the multiple hollow columns 3021 of the water disc 30 are inserted into the multiple hollow spray protrusions 502 of the outflow disc 50 respectively, and the stop rib 301 of the water disc 30 is fitted with the protruded rib 401 of the locking disc 40. Then, the peripheral rib 201 of the water supply cover 20 is covered on the locking disc 40 so that the multiple screws 2012 of the multiple fixing orifices 2011 of the peripheral rib 201 are locked into the multiple notches 402 of the locking disc 40 individually, such that the water supply cover 20 is connected with the locking disc 40, and the case 10 is covered on the water supply cover 20, the water disc 30, the locking disc 40, and the outflow disc 50.


However, the locking disc 40 is stacked on the outflow disc 50 so that the multiple hollow spray protrusions 502 are upward extended through the multiple orifices 501 of the outflow disc 50 and the multiple through holes 403 of the locking disc 40 respectively, and the multiple hollow spray protrusions 502 are riveted on the locking disc 40. In addition, the water disc 30 is stacked on the locking disc 40 so that the multiple hollow columns 3021 of the water disc 30 are inserted into the multiple hollow spray protrusions 502 of the outflow disc 50 respectively, so the conventional fixed showerhead structure is complicated, is connected troublesomely, and is manufactured at high fabrication cost and defective rate. Due to the locking disc 40 includes the protruded rib 401 arranged around the rim of the top thereof, the multiple notches 402 equidistantly defined outside the rim of the top of the locking disc 40, and the multiple through holes 403 formed inside the protruded rib 401 and corresponding to the multiple hollow columns 3021 of the water disc 30 individually, the locking disc 40 has a specific thickness, and the conventional fixed showerhead is not slim.


To overcome above-mentioned defects, a slim fixed showerhead is disclosed in FIGS. 15-20 and contains a water supply disc 60, a water guiding disc 70, and a covering casing 80, wherein the water supply disc 60 includes a first face 601, a second face 602 opposite to the first face 601, and a plurality of orifices 603 arranged on the water supply disc 60 and communicating with the first face 601 and the second face 602. The water supply disc 60 further includes multiple locking elements 604 welded proximate to a peripheral side of the second face 602 of the water supply disc 60, and each of the multiple locking elements 604 has an inner thread.


The water guiding disc 70 is flexible and contacts with the second face 602 of the water supply disc 60, and the water guiding disc 70 includes multiple spray protrusions 701 arranged on a first surface thereof facing the water supply disc 60 and inserted into the plurality of through orifices 603 of the water supply disc 60 respectively, wherein each spray protrusion 701 has a peripheral trench 702 defined around a peripheral side thereof, and a height of the peripheral trench 702 mates with a thickness of the water supply disc 60, such that the peripheral trench 702 retains with a respective one of the plurality of through orifices 603. The covering casing 80 is covered on the second face 602 of the water supply disc 60 and includes a plurality of first fixing holes 801 corresponding to the multiple locking elements 604 of the water supply disc 60 respectively, and a plurality of screws 802 inserted through the plurality of first fixing holes 801 so as to screw with the multiple locking elements 604 of the water supply disc 60 individually, thus connecting the covering casing 80 and the water supply disc 60 together. Furthermore, an accommodation room 90 is defined between the covering casing 80 and the water guiding disc 70, and the water guiding disc 70 is clamped between the covering casing 80 and the water supply disc 60, wherein the multiple spray protrusions 701 of the water guiding disc 70 are in communication with the accommodation room 90. The covering casing 80 includes a connecting knob 803 arranged on a central position thereof and configured to connect with a water source. In operation, water flows into the accommodation room 90 between the covering casing 80 and the water guiding disc 70 from the connecting knob 803, and sprays out of the multiple spray protrusions 701 of the water guiding disc 70, hence user takes a shower.


However, the multiple locking elements 604 of the slim fixed showerhead are welded on the second face 602 of the waters supply disc 60 to cause difficult machining, poor stability, and easy removal. Moreover, a positioning error of said each locking element 604 occurs to have defective rate, and a welding defacement happens on the first face 601 of the water supply disc 60, so polishing the first face 601 of the water supply disc 60 to eliminate the welding defacement will increase machining time and high production cost. After polishing the first face 601 of the water supply disc 60, a welding trace 601A remains on a welded position so have inferior quality and appearance of the slim showerhead structure.


The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
