Claims

[Scope of utility model registration request]

This is a liquid ejecting device in which a pump device 1 is fixed to a container mouth cylinder portion with a screw tube 2, and the pump device 1 includes a piston 5 having a communication hole 5a in a cylinder 4 having a first check valve 3 on the suction side. The piston 5 is urged to a raised position by a spring 6, and a spouting pipe 7 communicating with the communication hole 5a is connected to the piston 5, while being fixed to the upper outer periphery of the cylinder 4 with the screw tube 2. A flange 8 is provided, and a stopper 9 is fitted into the upper end opening, and the spouting pipe 7 passes through the through hole 9a provided in the plugging body 9, and a jetting head 10 is fitted at the tip of the spouting pipe 7. Attaching the spout 10a of the spouting head 10 from the piston 5
A second check valve 11 is provided at any point leading to the
When the piston 5 is raised by the spring 6, the second check valve 11 closes, the first check valve 3 opens, and the liquid inside the container is sucked into the cylinder 4, and the ejection head 1
When the piston 5 is lowered by pressing down the first
When the check valve 3 closes and the second check valve 11 opens, the liquid inside the cylinder 4 passes through the spout pipe 7 and is spouted out from the spout 10a.
When rising, the outer diameter of the spouting pipe 7 corresponding to the through-hole 9a of the stopper 9 is set to be the same as or slightly larger than the inside diameter of the through-hole 9a, and the outer diameter of the middle portion of the spouting pipe 7 is set to be larger than the inside diameter of the through-hole 9a. A seal body 12 is formed integrally with the ejection head 10, which is made slightly smaller and fits over the plug body 9 to hold the ejection head 10 in a lowered state.
A liquid ejecting device characterized in that a break line 13 is formed around the periphery of the seal body 9 so that the seal body 12 can be separated from the plug body 9 by breaking the break line 13.
