  When the operating lever 3 is manually operated and pulled toward the pump 2 to the stroke end position, the first check valve 33b is closed and the piston 35 is pushed into the partition cylinder 34b to increase the hydraulic pressure in the pump 2. Then, the liquid in the pump 2 is sent out from the hole 34d to the internal passage P through the second check valve 33c.

Here, the case where the nozzle 6 is first rotationally adjusted around the central axis C and the spray pattern is set to shower will be described. FIG. 3A is a cross-sectional view in which a part of the nozzle 6 and the connecting member 4 is cut along the cross-section AA in FIG. 2B, and the liquid in the container 20 is ejected in a shower state. The position of the nozzle 6 is shown. In FIG. 3A, the rotational position of the nozzle 6 is adjusted so that the second passage 4b ₁ and the second nozzle side passage 6e ₁ are at the same position on the circumference. For this reason, the content liquid pumped by the pump 2 passes through the second nozzle side passage 6e ₁ and the second passage 4b _1, and the second ejection holes are provided at eight equal intervals on the circumference. From 6b ₁ it becomes a shower state and is ejected. In the present embodiment, the second nozzle side passage 6e ₁ and the second passage 4b ₁ are provided at two positions on the circumference, but the present invention is not limited to this mode. You may provide in one place or three or more places in the range which does not have trouble in operation | movement of another injection pattern.

Next, the case where the nozzle 6 is further rotationally adjusted around the central axis C and the spray pattern is set to fog will be described. FIG. 3B is a cross-sectional view in which a part of the nozzle 6 and the connecting member 4 is cut along the cross-section BB in FIG. 2B, and the content liquid in the container 20 is sprayed in a mist state. The position of the nozzle 6 is shown. In FIG. 3B, the rotational position of the nozzle 6 is adjusted so that the first passage 4a ₁ and the first nozzle side passage 6f ₁ are at the same position on the circumference. For this reason, the content liquid pumped by the pump 2 is ejected in a fog state from the first ejection hole 6a ₁ via the first nozzle side passage 6f ₁ and the first passage 4a ₁ . In the present embodiment, the first nozzle side passage 6f ₁ and the first passage 4a ₁ are also provided at two positions on the circumference opposite to each other, but the present invention is not limited to this mode. You may provide in one place or three or more places in the range which does not have trouble in operation | movement of another injection pattern.

  Next, the case where the rotation of the nozzle 6 is adjusted and the ejection of the content liquid from the nozzle 6 is in a stopped state will be described. FIG. 4 is a diagram showing a partial cross section of the nozzle 6 and the connecting member 4 when the ejection of the content liquid is set to a stopped state. 4A is a cross-sectional view taken along the section AA in FIG. 2B, and FIG. 4B is a cross-sectional view taken along the section BB.

However, the second nozzle side passage 6e second passage 4b ₁ which is provided opposite to _1, the same position on the second ejection hole 6b ₁ and second nozzle side passage 6e ₁ and circumferential Absent. For this reason, in the state shown in FIG. 4A, the second ejection hole 6b ₁ and the second passage 4b ₁ do not communicate with each other, so the contents from the internal passage P are ejected from the second ejection hole 6b _1. Never happen.

However, the first passage 4a ₁ is provided opposite the first nozzle side passage 6f _1, in the same position of the first ejection holes 6a ₁ and first nozzle side passage 6f on ₁ and circumference Absent. For this reason, in the state shown in FIG. 4B, since the first ejection hole 6a ₁ and the first passage 4a ₁ do not communicate with each other, the contents from the internal passage P are ejected from the first ejection hole 6a _1. Never happen.

In the present embodiment, the first passage 4a ₁ and the second passage 4b ₁ provided on the connecting member 4 side are arranged at the same position on the circumference, and they are arranged in the first ejection hole 6a. Together the _first and the first nozzle side passage 6f ₁ the first contents from the injection holes 6a ₁ is ejected as a mist, the second ejection holes 6b ₁ and the second match the nozzle side passage 6e ₁ second The contents can be ejected from the two ejection holes b ₁ in a shower shape. However, the present invention is not limited to this mode. For example, when the first passage 4a ₁ is aligned with the first ejection hole 6a ₁ and the first nozzle side passage 6f ₁ , the second passage 4b ₁ is the second passage 4b ₁ . The first passage 4a ₁ and the second passage 4b ₁ can be arranged at different positions on the circumference so as to match the ejection holes 6b ₁ and the second nozzle side passage 6e ₁ . In this case, when the nozzle 6 is adjusted to a predetermined angle, the contents can be ejected in a mist form from the first ejection hole 6a ₁ , and at the same time, the contents can be ejected from the second ejection hole 6b ₁ in a shower shape. .

  When the operation of the operation lever 3 is released, the operation lever 3 is returned to the initial position by the elastic force of the leaf spring 63, and the second check valve 33c is closed and the first check valve 33b is moved along with the return operation. Opened, the liquid in the container 20 is sucked into the pump 2 from the hole 34d through the suction pipe 17 and the first check valve 33b.

The outside air introduction port 34e communicates the inside and outside of the cylinder tube 34a and communicates with a hole 32f provided in the fitting wall 32e through a gap formed between the fitting wall 32e and the cylinder tube 34a. Yes. The air sucked from the outside air inlet 34e passes through the hole 32f after passing through the gap between the cylinder cylinder 34a of the pump 31 and the fitting wall 32e, as shown by the broken line arrow in FIG. The air that has passed through the hole 32 f is sucked into the container 20 through the hole 33 g provided in the intake 33. As a result, air is replaced in the container 20 by the amount of ejection of the content liquid.

  As described above, the liquid ejector 100 is attached to the mouth portion 21 of the container 20, and the pulling operation and the releasing operation of the operation lever 3 are repeated, whereby the pump 2 is operated and the liquid in the container 20 is changed to the first reverse direction. It sends to the nozzle 6 through the stop valve 33b and the second check valve 33c. Then, the content liquid can be ejected in the ejection pattern selected by the rotation operation of the nozzle 6.

As described above, according to the present embodiment, the content pumped by the pump 2 is provided in the nozzle 6 and the first passage 4a ₁ that is provided in the connecting member 4 and extends in the ejection direction of the content. When passing through the first ejection hole 6a _1, and ejected in the first ejection pattern, and through the second passage 4b ₁ and the second ejection hole 6b ₁ provided in the nozzle 6 In this case, the second jet pattern is used for jetting. Thereby, since a flow path can be optimized for every injection pattern, it becomes possible to produce | generate a different injection pattern reliably.

  Moreover, according to this embodiment, since the nozzle 6 can be rotated around the central axis C to switch the ejection pattern and stop the ejection, the operation of the liquid ejector 100 is facilitated.
