Abstract

A shower head includes a body provided with a waterway. A first switch is movably mounted on the body to be responsible for selectively opening and closing the waterway and a second switch movably mounted on the body to be responsible for selectively changing water output patterns. The first switch has a rear pushbutton, a driving rod movably connected to the rear pushbutton and a diverting element movable relative to the body to be responsible for closing or opening the waterway. The second switch has a front pushbutton, a sliding element having a rack formed on a face thereof, a diverter rotatably received inside the body, a gear rotatably received inside the body and having first ratchet teeth and a rotor having second ratchet teeth selectively engaged with the first ratchet teeth to allow the rotation of the gear to drive the second ratchet teeth of the rotor to disengage with the first ratchet teeth of the gear as well as the rotor and the diverter to rotate accordingly.

Claims

1. A shower head comprising:

a body provided with a waterway;

a first switch movably mounted on the body to be responsible for selectively opening and closing the waterway; and

a second switch movably mounted on the body to be responsible for selectively changing water output patterns, comprising;

a front pushbutton movable relative to the body;

a sliding element movably received inside the body and having a rack formed on a face thereof;

a diverter rotatably received inside the body;

a gear rotatably received inside the body and having teeth formed on a peripheral edge thereof to engage with the rack of the sliding element to allow linear movement of the sliding element to drive the gear to rotate and first ratchet teeth formed on a side face thereof; and

a rotor firmly mounted to the diverter and having second ratchet teeth selectively engaged with the first ratchet teeth to allow the rotation of the gear to drive the second ratchet teeth of the rotor to disengage with the first ratchet teeth of the gear as well as the rotor and the diverter to rotate accordingly.

2. The shower head as claimed in claim 1, wherein the first switch comprises:

a rear pushbutton movable relative to the body;

a driving rod movably connected to the rear pushbutton; and

a diverting element movable relative to the body and operably connected to the driving rod to be responsible for closing or opening the waterway.

3. The shower head as claimed in claim 2, wherein the first switch further has a first recoil spring provided between an inner face of the body and a side face of the diverting element to provide a recoil force to the diverting element after the diverting element is moved.

4. The shower head as claimed in claim 3, wherein the driving rod has first ratchet teeth formed on a side face thereof and the diverting element has second ratchet teeth formed on a side face thereof to disengageably connect to the first ratchet teeth to allow the movement of the driving rod to drive the diverting element to rotate accordingly, which opens or closes the waterway of the body.

5. The shower head as claimed in claim 2, wherein the driving rod has first ratchet teeth formed on a side face thereof and the diverting element has second ratchet teeth formed on a side face thereof to disengageably connect to the first ratchet teeth to allow the movement of the driving rod to drive the diverting element to rotate accordingly, which opens or closes the waterway of the body.

6. The shower head as claimed in claim 1 further comprising a recoil spring provided between an inner face of the body and a distal end of the sliding element to provide a recoil force to the sliding element after the sliding element is moved.

7. The shower head as claimed in claim 6, wherein the driving rod has first ratchet teeth formed on a side face thereof and the diverting element has second ratchet teeth formed on a side face thereof to disengageably connect to the first ratchet teeth to allow the movement of the driving rod to drive the diverting element to rotate accordingly, which opens or closes the waterway of the body.

8. The shower head as claimed in claim 7, wherein the second switch further has a second recoil spring provided between an inner face of the body and a side face of the rotor to provide a recoil force to the rotor after the rotor is moved.

9. The shower head as claimed in claim 6, wherein the second switch further has a second recoil spring provided between an inner face of the body and a side face of the rotor to provide a recoil force to the rotor after the rotor is moved.

10. The shower head as claimed in claim 1, wherein the driving rod has first ratchet teeth formed on a side face thereof and the diverting element has second ratchet teeth formed on a side face thereof to disengageably connect to the first ratchet teeth to allow the movement of the driving rod to drive the diverting element to rotate accordingly, which opens or closes the waterway of the body.

11. The shower head as claimed in claim 10, wherein the second switch further has a second recoil spring provided between an inner face of the body and a side face of the rotor to provide a recoil force to the rotor after the rotor is moved.

12. The shower head as claimed in claim 1, wherein the second switch further has a second recoil spring provided between an inner face of the body and a side face of the rotor to provide a recoil force to the rotor after the rotor is moved.
