Trigger-type liquid sprayer

A trigger-type liquid sprayer comprising:

• a sprayer main body mounted on a container body configured to accommodate a liquid therein;
• and
• a nozzle member having a spray hole for spraying a liquid forward, the nozzle member being mounted on a front end portion of the sprayer main body,
• wherein the sprayer main body includes:
• a vertical supply tube extending in an upward/downward direction and configured to suck up a liquid in the container body;
• a trigger mechanism having a trigger portion disposed in front of the vertical supply tube to be movable rearward in a state in which the trigger portion is biased forward, the trigger mechanism being configured to cause the liquid to flow from an inside of the vertical supply tube toward the spray hole in response to rearward movement of the trigger portion;
• a reservoir cylinder into which a liquid that has passed through the inside of the vertical supply tube is supplied in response to rearward movement of the trigger portion;
• and
• a reservoir plunger disposed inside the reservoir cylinder to be movable in an axial direction along a center axis of the reservoir cylinder, and configured to move toward one side in the axial direction in response to supply of the liquid into the reservoir cylinder while being biased toward the other side in the axial direction by a bias member, and
• the vertical supply tube has:
• a recovery path disposed in a rear end portion of the vertical supply tube, extending downward from the reservoir cylinder, and having a lower end portion closed from below and an upper end that opens upward;
• a communication path extending in a circumferential direction of the vertical supply tube from the recovery path;
• and
• a communication opening disposed in front of the recovery path and configured to allow the communication path and the inside of the container body to communicate with each other.
