DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.

[0027] With reference to FIGS. 1-4, a curved plastic faucet in accordance with a preferred embodiment of the present invention comprises: a body 10, an arcuate tube 20, a connector 30, a cap 40, a supply head 50, and a bubble dispenser 60.

[0028] The body 10 is made using plastic injection molding, and the body 10 includes a connection member 11 and is in connection with a water supply source and a control valve, wherein the control valve controls water to flow toward the connection member 11 from the water supply source.

[0029] The arcuate tube 20 is integrally injection molded from electroplatable plastic, and the arcuate tube 20 includes an inflow segment 21 and an outflow segment 22, wherein the inflow segment 21 is coupled with the connection member 11 and communicates with the water supply source, and the arcuate tube 20 further includes an arc-shaped section 23 extending to circumference length of the inflow segment 21 from the outflow segment 22, an arcuate water conduit 24 defined in the arc-shaped section 23, wherein two ends of the arcuate water conduit 24 are in connection with the inflow segment 21 and the outflow segment 22 respectively, wherein the arcuate water conduit 24 has an imaginary arc line A1 defined on a center thereof, and the imaginary arc line A1 is an arcuate section of a circle and a length of the arcuate section is not more than of the circle, wherein a first radius R1 is defined on a central section of the imaginary arc line A1, a second radius R2 is adjacent to the inflow segment 21, and a third radius R3 is close to the outflow segment 22, wherein the first radius R1, the second radius R2, and the second radius R3 are equal. A cross section of the arcuate water conduit 24 proximate to the inflow segment 21 is not more than that of the outflow segment 22, and an outlet 25 is defined adjacent to a lower end of the outflow segment 22 so that a part of the outflow segment 22 in the outlet 25 has a limitation portion 26 formed thereon.

[0030] The connector 30 is made using plastic injection molding, and the connector 30 includes an inlet 31 defined on a first end thereof and extending downward to a second end of the connector 30 so as to communicate with an opening 32 and to cooperate with a profile and the cross section of the arcuate water conduit 24, a first screwing portion 33 formed on the opening 32 and being outer threads, at least one stop ring 34 adjacent to an outer rim of the inlet 31, wherein the connector 30 is connected into the arcuate water conduit 24 from the outflow segment 22 so that at least one stop ring 34 stops the water leaking from the outflow segment 22 and the outlet 25, and the opening 32 corresponds to the outlet 25.

[0031] The cap 40 is injection molded from electroplatable plastic and cooperates with a shape of the outflow segment 22, the cap 40 covers and closes the outflow segment 22.

[0032] The supply head 50 includes a guide space defined on a center thereof so as to flow the water, and the supply head 50 includes a second screwing portion 51 mating with the first screwing portion 33, wherein the second screwing portion 51 is inner threads, such that after the supply head 50 passes through the outlet 25 and the connector 30, the limitation portion 26 limits an extending direction of the arcuate water conduit 24, as shown in FIGS. 5 and 6.

[0033] The bubble dispenser 60 is housed in the supply head 50 so that when the water flows through the bubble dispenser 60, the bubble dispenser 60 produces bubbles.

[0034] Referring to FIGS. 1, 3, and 7, in use, after the water flows into the body 10, it is switched to stop flow or to flow into the inflow segment 21 of the arcuate tube 20 via the connection member 11, and the water flows into the inlet 31 of the connector 30 from the arcuate water conduit 24, then the water flows out of the bubble dispenser 60 from the opening 32 via the supply head 50.

[0035] When the water flows into the arcuate water conduit 24 of the arcuate tube 20, the connector 30 is pushed by a pressure of the water. Due to the supply head 50 is locked with the connector 30 in another direction, and the connector 30 is limited by the limitation portion 26 in the extending direction of the arcuate water conduit 24, the connector 30 is not pushed out of the arcuate water conduit 24 by the pressure of the water, hence the connector 30 is not limited in a conventional high frequency manner or in an adhesive manner.

[0036] Accordingly, the arcuate tube 20 further includes the arc-shaped section 23 extending to circumference length of the inflow segment 21 from the outflow segment 22, the arcuate water conduit 24 has the imaginary arc line A1 defined on the center thereof, the imaginary arc line A1 is the arcuate section of the circle and a length of the arcuate section is not more than of the circle so that the first radius R1, the second radius R2, and the second radius R3 are equal, wherein the cross section of the arcuate water conduit 24 proximate to the inflow segment 21 is not more than that of the outflow segment 22, such that the arcuate tube 20 is manufactured integrally so as to obtain aesthetic appearance, to reduce components, to avoid using high frequency connection and coating protective oil, and to lower fabrication cost. Furthermore, the outlet 25 is defined adjacent to the lower end of the outflow segment 22 so that the limitation portion 26 is formed between the outlet 25 and the outflow segment 22, when the connector 30 is connected into the arcuate water conduit 24 from the outflow segment 22, and the supply head 50 is coupled with the connector 30 via the outlet 25, the connector 30 is limited by the limitation portion 26 in the extending direction of the arcuate water conduit 24 so as to avoid the connector 30 being pushed out of the arcuate water conduit 24 by the pressure of the water. Preferably, the cap 40 is not forced by the pressure of the water, and the curved plastic faucet is manufactured easily without using the conventional high frequency connection.

[0037] While various embodiments in accordance with the present invention have been shown and described, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
