Trigger-type liquid sprayer

A trigger-type liquid sprayer comprising:

• a sprayer body mounted on a container body in which a liquid is accommodated;
• and
• a nozzle member mounted on the sprayer body, and provided with a spray hole through which the liquid is sprayed,
• wherein the sprayer body includes:
• a vertical feed tube portion configured to suck up the liquid in an inside of the container body;
• a connecting tube portion extending from the vertical feed tube portion, and having an opening portion that opens outside the sprayer body;
• a sealing plug mounted in the connecting tube portion to close the opening portion;
• a trigger mechanism having a trigger part disposed to be movable rearward in a forward biased state, and configured to flow the liquid toward the spray hole from an inside of the vertical feed tube portion through an inside of the connecting tube portion according to rearward movement of the trigger part;
• a reservoir cylinder provided with a communication hole in communication with the spray hole and a feed hole in communication with the inside of the connecting tube portion, and into which the liquid passing through the inside of the vertical feed tube portion and the inside of the connecting tube portion is supplied through the feed hole according to rearward movement of the trigger part;
• a reservoir plunger disposed in the reservoir cylinder to be movable in an axial direction along a center axis of the reservoir cylinder, configured to move toward one side in the axial direction according to supply of the liquid into the reservoir cylinder, and biased toward the other side;
• and
• a recovery mechanism configured to recover an internal pressure of the connecting tube portion through the feed hole,
• the reservoir plunger is configured to block communication between an inside of the reservoir cylinder and the spray hole through the communication hole, and configured to allow communication between the inside of the reservoir cylinder and the spray hole through the communication hole when moved to the one side, and
• the recovery mechanism is configured to allow communication between the inside of the connecting tube portion and the inside of the container body through a space between an inner circumferential surface of the reservoir cylinder and an outer circumferential surface of the reservoir plunger, and configured to release the recovered internal pressure of the connecting tube portion toward the container body.
