Abstract

The present invention is provided with a pat-switching sprinkler, which is provided with a fixation unit ( 100 ), an operation bat ( 200 ) and switching mechanism ( 300 ). The fixation unit ( 100 ) is provided with a water entry ( 110 ) and multiple water exits ( 120 ) which can get through with the water entry ( 110 ). The operation bat is provided with an operation part ( 210 ), a connection part ( 220 ) and a pin-jointed part ( 230 ), which pivots the fixation unit. The connection part ( 220 ) and the operation part ( 210 ) respectively lie at the inner side and external side of the fixation unit. The switching mechanism ( 300 ) is arranged in the fixation unit ( 100 ) and is in transmission with the connection part ( 220 ). It has advantages as below: swing the operation bat by patting it, which can put the switching mechanism in motion to switch the water exits. Thus, it saves the switching force and can be switched reliably and conveniently.

First claim

What is claimed is:

1. A pat-switching sprinkler, comprising
a fixation unit, which is provided with a water entry and multiple water exits which can be connected to the water entry;
an operation bat, which is provided with an operation part, a connection part, a pin-jointed part that is arranged between the operation part and connection part;
the pin-jointed part pivots the fixation unit,
the connection part and the operation part respectively lie at an inner side and an external side of the fixation unit;
a switching mechanism, is arranged in the fixation unit and in transmission with the connection part;
the fixation unit is provided with a first gear,
the switching mechanism comprises a central shaft, slidably connected to the fixation unit, and a second gear arranged on the central shaft;
a switching panel, a third gear being arranged on a center part of the switching panel, configured to rotate and slide with the fixation unit, so that the water exits are switched by rotation of the third gear;
a resetting spring, which presses against the switching panel;
wherein, the third gear is configured to match up with the first gear and the second gear, so that the operation part swings by patting, the central shaft raises up, then the resetting spring stores energy, the second gear and the third gear match up to make the switching panel raise up and rotate forward,
the resetting spring releases the energy, then, the switching panel moves down, the first gear and the third gear match up to make the switching panel rotate forward to switch the water exits, and
the central shaft and the operation bat reset.

2. A pat-switching sprinkler according to claim 1 , wherein the fixation unit further comprising a water-out terminal, where the multiple water exits are arranged, and the water exits' ports are circlewise displayed on the switching surface of the water-out terminal;
an upper cover, which is fixedly connected to the water-out terminal hermetically and covers the water exits' ports in it;
the switching chamber is formed between the upper cover and the water-out terminal;
a shell, which is fixedly connected to the water-out terminal and the upper cover is covered in it;
a water conduit, which is fixedly connected to the shell in the upper end and can be connected to the external water supply, and that is fixedly connected to the upper cover in the lower end and can be connected to the switching chamber.

3. A pat-switching sprinkler according to claim 2 , wherein the operation bat's pin-jointed part pivots the shell, and the connection part and the operation part respectively lie at the inner side and external side of the shell, the switching mechanism is connected to the upper cover.

4. A pat-switching sprinkler according to claim 1 , wherein a sliding chute is arranged on the connection part;
a toroidal chute is arranged on the upper end of the central shaft;
the switching mechanism further comprises a lever, the central part of the lever pivots to the fixation unit;
the first end of the lever is adaptively connected to the sliding chute by a pin, a prong is arranged on the second end of the lever, which plugs the toroidal chute, to make the operation bat's swinging and the central shaft's sliding form a linkage.

5. A pat-switching sprinkler according to claim 4 , wherein
the first gear is arranged on the switching surface, the second gear is arranged on the lower end of the central shaft, the switching panel is arranged in the switching chamber;
the central shaft is slidably connected to the upper cover hermetically and the lower end is in the switching chamber, the upper end stretches out on the upper cover;
the central part of the lever pivots on the upper cover;
the resetting spring is muff-connected to the central shaft and presses between the switching panel and the upper cover.

6. A pat-switching sprinkler according to claim 4 , further comprising:
a ratchet, which can rotate with the fixation unit and form the synchronous and coaxial rotation relationship with the switching panel;
a pawl, which is provided with a pin socket, stirring jaw and a pressing jaw, the pin socket pivots to the fixation unit;
the resetting spring is connected to the pawl and fixation unit;
wherein, the stirring jaw and the pressing jaw all match up with the ratchet, so that the operation part swings by patting, the pawl rotates forward,
the stirring jaw presses against the ratchet to make it rotate forward and the resetting spring stores energy;
when rotating into place, the pressing jaw presses against the ratchet to position the ratchet,
the resetting spring releases energy to make the pawl reverse and reset, and the operation bat resets.

7. A pat-switching sprinkler according to claim 3 , wherein
a sliding chute is arranged on the connection part;
a toroidal chute is arranged on the upper end of the central shaft;
the switching mechanism further comprises a lever, the central part of the lever pivots to the fixation unit;
the first end of the lever is adaptively connected to the sliding chute by a pin, a prong is arranged on the second end of the lever, which plugs the toroidal chute, to make the operation bat's swinging and the central shaft's sliding form a linkage.

8. A pat-switching sprinkler according to claim 7 , wherein
the first gear is arranged on a switching surface, the second gear is arranged on the lower end of the central shaft, the switching panel is arranged in the switching chamber;
the central shaft is slidably connected to the upper cover hermetically and the lower end is in the switching chamber, the upper end stretches out on the upper cover;
the central part of the lever pivots on the upper cover;
the resetting spring is muff-connected to the central shaft and presses between the switching panel and the upper cover.

9. A pat-switching sprinkler according to claim 7 , further comprising:
