Abstract:
1. A trigger-type liquid sprayer comprising: a liquid sprayer body including a nozzle and a trigger lever and a shroud covering the liquid sprayer body in which a liquid is sprayed from a spray hole of the nozzle by a pulling operation of the trigger lever, the nozzle being rotatable with respect to the liquid sprayer body and provided so that a flow passage of the liquid is opened and closed according to a rotational position of the nozzle when an operation lever mounted on the nozzle is rotationally moved between opened and closed positions, respectively; an abutment portion being provided at the shroud for positioning the nozzle at a position where the flow passage is opened by having the operation lever abutted to the abutment portion in the opened position; a first cylindrical portion including a first groove; and a second cylindrical portion that is radially offset with respect to the first cylindrical portion, the second cylindrical portion including a second groove, and the second cylindrical portion being configured to rotate with respect to the first cylindrical portion i) so as to radially align the second groove with the first groove to open the flow passage, and ii) so as to radially misalign the second groove with respect to the first groove to close the flow passage, wherein the trigger lever travels along an actuation path in a pull direction and an opposing release direction, the pull direction corresponding to a direction of the pulling operation on the trigger lever; the operation lever includes a rod that is fixed to the nozzle, a knob that is fixed to the rod, and a projection that is fixed to the knob, such that, when the flow passage is closed by the nozzle through rotational movement of the operation lever to the closed position, the rod is provided to be accommodated in front of the trigger lever, so that the trigger lever is inhibited from extending further along the actuation path in the release direction, the knob is provided so as to extend, in the pull and release directions, across a side of the trigger lever, and the projection is provided as to extend behind the trigger lever to inhibit the trigger lever from extending further along the actuation path of the trigger lever in the pull direction; the trigger lever includes a space provided by a recess in a front face portion of the trigger lever on a side of the trigger lever including a rotation center, the recess being a stepped portion; the stepped portion includes a reinforcing rib that extends between a base surface of the stepped portion and a depth surface rising from the base surface, the base surface extending in the pull and release directions, and the depth surface and the reinforcing rib extending vertically from the base surface; and when the operation lever is in the closed position, the reinforcing rib functions as a stopper for the operation lever by contacting the rod of the operation lever.
