Patent ID: 7370814

Claim:
A sprinkler with sprinkling figures changeable with single hand, comprising: a main body possessing a channel inside, one end of the channel of the main body being formed with a water inlet, while the other end of the channel of the main body being formed with a water outlet from which a water flow outgoes; a sprinkling head possessing an outside side and an inner side oppositely, the sprinkling head being formed with multiple annularly arranged subchannels designed with various sprinkling figures at the outside side, the subchannels communicating with two opposite sides of the sprinkling head, the sprinkling head being rotatably connected with one end of the main body corresponding to the water outlet, whereby one end of each subchannel is in alignment with the water outlet for receiving the water flow coming from the water outlet, a rotational axis of the sprinkling head corresponding to a direction of the water flow; a driving unit disposed between the main body and the sprinkling head, the driving unit including at least one force application member and a driven section, the force application member being reciprocally movably disposed between the main body and the sprinkling head, the driven section being positioned between the main body and the sprinkling head, the force application member serving to drive the driven section to drive and rotate the sprinkling head; and the driven section is disposed on the inner side of the sprinkling head, which side faces the water outlet, the driven section including a first driven section and a second driven section, the force application member being disposed between the first and second driven sections, one end of the force application member having a first driving section and a second driving section, the first driven section including multiple guide slopes annularly arranged on the inner side of the sprinkling head, an axis of the first driven section coinciding with the rotational axis of the sprinkling head, the second driven section including a stem section and multiple guide slopes annularly disposed on the stem section, the stem section being connected to the inner side of the sprinkling head, an axis of the second driven section coinciding with the rotational axis of the sprinkling head, the first and second driving sections respectively corresponding to the first and second driven sections, each of the first and second driving sections having at least one guide slope, whereby when the force application member is moved, the guide slope of the first driving section and the guide slope of the second driving section respectively at different times slide along one guide slope of the first driven section and one guide slope of the second driven section.
