## Abstract

A combination showerhead with push button switching comprises a fixing holder, two showerheads and a switching mechanism. The first showerhead is mounted to the fixing holder; the fixing holder comprises an inlet passage connected to a supporting arm and two diversion passages connected to two showerheads respectively. The switching mechanism comprises a diversion plate, a valve core, a push button and an elastomer. The diversion plate is connected to the fixing holder movably and cooperates with the inlet and diversion passages to switch waterways by rotating a predetermined angle. The valve core is slidably connected to the fixing holder and connected to the diversion plate to drive the diversion plate to rotate by back-and-forth sliding. The push button is movably connected to the fixing holder and connected to the valve core to drive the valve core to slide by a user's pushing.

## Claims

### Claim 1

A combination showerhead with push button switching comprising:
a fixing holder mounted to a supporting arm;
a first showerhead mounted to the fixing holder;
a second showerhead; and
a switching mechanism;
the fixing holder comprising an inlet passage connected to the supporting arm and at least two diversion passages;
one of the at least two diversion passages being connected to the second showerhead and another of the at least two diversion passages being connected to the first showerhead;
wherein the switching mechanism comprises:
a diversion plate movably connected to the fixing holder, and cooperating with the inlet passage and the at least two diversion passages to switch waterways by rotating a predetermined angle;
a valve core slidably connected to the fixing holder and connected to the diversion plate to drive the diversion plate to rotate the predetermined angle by back-and-forth sliding;
a push button movably connected to the fixing holder and connected to the valve core to drive the valve core to slide in response to pushing;
an elastomer to reset the valve core; and
a shaft fixed to the diversion plate; and wherein
an end of the valve core, an end of the shaft, and the fixing holder each have ratchets;
the diversion plate is rotatable and movable along a rotation axis relative to the fixing holder;
the elastomer is between the diversion plate and the fixing holder;
the ratchets work in co-ordination;
back-and-forth sliding of the valve core drives the shaft along with the diversion plate to cause the diversion plate to rotate the predetermined angle;
the push button is slidably connected to the fixing holder;
the push button comprises a fixing plate;
a forking part is formed on an end of the fixing plate;
the valve core comprises a connecting groove;
the forking part inserts into the connecting groove; and
the push button drives the valve core to slide.

### Claim 2 (depends on 1)

The combination showerhead with push button switching according to claim 1, wherein:
a back of the fixing holder has an assembly portion;
the switching mechanism is disposed inside the assembly portion; and
the push button is movably connected to the assembly portion with at least part of the push button located outside the assembly portion for pushing.

### Claim 3 (depends on 2)

The combination showerhead with push button switching according to claim 2, wherein:
the second showerhead has a handle;
an outlet of the at least two diversion passages connected to the second showerhead is disposed on a sidewall of the assembly portion;
the handle connects with the outlet through a flexible hose; and
a front lower part of the fixing holder has a connecting portion for positioning the handle.

### Claim 4 (depends on 2)

The combination showerhead with push button switching according to claim 2, wherein:
the fixing holder has a common portion;
two forking portions extend from the common portion;
the first showerhead rotatably connected between the two forking portions;
a hose piece disposed along a rotation axis of the first showerhead is connected to the first showerhead, and part of the at least two diversion passages is disposed along the hose piece.

### Claim 5 (depends on 4)

The combination showerhead with push button switching according to claim 4, wherein the assembly portion is disposed on a back of the common portion.

### Claim 6 (depends on 2)

The combination showerhead with push button switching according to claim 2, wherein:
the first showerhead is rotatably connected to the fixing holder; and
a damping mechanism is disposed between the fixing holder and the first showerhead.

### Claim 7 (depends on 6)

The combination showerhead with push button switching according to claim 6, wherein:
the damping mechanism comprises a locating holder, a turning block and a cam;
at least two pieces disposed separately in a circumferential direction on the locating holder form a rotary sleeve having at least part of an inner wall with changing radii;
the cam is disposed in the rotary sleeve to match the changing radii;
the turning block is sleeves the rotary sleeve; and
friction force of the pieces and the turning block changes with rotation of the cam relative to the changing radii to change damping.

### Claim 8 (depends on 2)

The combination showerhead with push button switching according to claim 2, wherein:
the fixing holder has a common portion and the first showerhead is rotatably connected to the common portion;
at least a hose piece disposed along a rotation axis of the first showerhead is connected to the first showerhead; and
part of the at least two diversion passages is disposed along the hose piece.
