Abstract

A multifunctional shower head, has a fixed seat, a driving mechanism, a water diversion plate rotatably connected to the fixed seat and a water diversion body. The water diversion body has a plurality of water diversion holes that are used to connect to the outlet functions of the shower head. The water diversion plate has an outlet hole. The driving mechanism drives the water diversion plate to rotate on the water diversion body, so that the outlet hole is alternately connected to part of the water diversion holes to switch the outlet functions of the shower head. A sealing ring is clamped between the water diversion plate and the fixed seat. The sealing ring defines a separating area on the upper surface of the water diversion plate, each water diversion hole has an O-ring, the bottom surface of the water diversion plate is pressed and contacts the O-ring.

First claim

The invention claimed is:

1. A multifunctional shower head having a plurality of shower outlets, comprising:
a fixed seat;
a water diversion plate rotatably connected to the fixed seat, having top and bottom surfaces through which a passage is defined, and having defined therein at least one outlet hole;
a sealing ring that is clamped between the water diversion plate and the fixed seat, and that defines a separating area on the top surface of the water diversion plate;
a driving mechanism;
a water diversion body disposed below the water diversion plate, and having a plurality of water diversion holes defined therein that selectively connect to respective ones of the shower outlets of the multifunctional shower head;
a plurality of O-rings positioned on respective ones of the plurality of water diversion holes and pressed to the bottom surface of the water diversion plate; and
an elastic piece that tightly presses the water diversion plate to the O-rings,
wherein the driving mechanism drives the water diversion plate to rotate with respect to the water diversion body so that one outlet hole of the at least one outlet hole of the water diversion plate is alternately connected to at least one of the water diversion holes so as to switch the shower outlets of the multifunctional shower head from one to another,
wherein the O-rings positioned on respective ones of the plurality of water diversion holes that are selectively disconnected from the at least one outlet hole define a non-water area on the bottom surface of the water diversion plate,
wherein the plurality of water diversion holes includes at least two water diversion holes that are arranged annularly so that two adjacent water diversion holes have a distance there between of 60 degrees,
wherein the at least one outlet hole includes at least two outlet holes that are arranged annularly so that two adjacent outlet holes have a distance there between of 90 degrees, and
wherein the driving mechanism is a pressing type driving mechanism that drives the water diversion plate to rotate with respect to the water diversion body by 30 degrees each time engaged.

2. The multifunctional shower head according to claim 1 , wherein the at least two water diversion holes are divided into three groups that are respectively connected to three waterways, one waterway of the three waterways having a flow volume that is less than that of the other waterways.

3. The multifunctional shower head according to claim 2 , wherein the fixed seat comprises:
a main body having an inlet waterway integrally molded therein and having a bottom surface; and
a metal mold insert fixedly connected to the bottom surface of the main body.

4. The multifunctional shower head according to claim 1 , wherein the fixed seat comprises:
a main body having an inlet waterway integrally molded therein and having a bottom surface; and
a metal mold insert fixedly connected to the bottom surface of the main body.

5. The multifunctional shower head according to claim 1 , wherein the driving mechanism comprises:
a button;
a swing piece pivotally joined to the fixed seat and connected to the button;
a slide piece joined to the swing piece;
a ratchet;
a ratchet wheel connected to the ratchet;
a reposition piece used to drive the ratchet to reposition the ratchet; and
a transmission connected to the water diversion plate and the ratchet wheel, and
wherein pressing the button causes the swing piece to push the slide piece to slide, and the slide piece drives the ratchet to push the ratchet wheel to rotate.

6. The multifunctional shower head according to claim 5 , wherein the driving mechanism further comprises a stop claw that is connected to the fixed seat and that corresponds to the ratchet wheel.

7. The multifunctional shower head according to claim 5 , wherein the ratchet has an end portion, wherein the reposition piece is an elastic arm that is connected to the end portion of the ratchet, and wherein the fixed seat is disposed with a stop block corresponding to the reposition piece.

8. The multifunctional shower head according to claim 5 , wherein the reposition piece is a spring that engages the fixed seat, and wherein the ratchet is disposed with a withstanding arm that pressingly engages the spring.

9. The multifunctional shower head according to claim 5 , wherein the reposition piece is a spring that engages the fixed seat and is connected between the slide piece and the fixed seat, and wherein the ratchet is locked catch to the slide piece.

10. The multifunctional shower head according to claim 1 , wherein the fixed seat comprises:
a main body having an inlet waterway integrally molded therein and having a bottom surface; and
a metal mold insert fixedly connected to the bottom surface of the main body.

11. The multifunctional shower head according to claim 1 , wherein the fixed seat comprises; a main body having an inlet waterway integrally molded therein and having a bottom surface; and a metal mold insert fixedly connected to the bottom surface of the main body.
