By configuring so as to form the hole, the second ejection hole having a small diameter can be formed more stably.

  As shown in FIGS. 1 and 2, an annular protrusion 46 e that protrudes forward is provided at the front end of the sub-plate 45 on the radially outer side of the plurality of grooves 46 a (second ejection holes). By forming the annular protrusion 46e in this manner, even if a small amount of content leaks from the second ejection hole after the contents are ejected from the second ejection hole, the annular projection 46e It is possible to suppress drooping outward in the radial direction.

  The fitting part 46 of the sub-plate 45 is connected to the outer frame part 46c via the arm part 46b as shown in the figure. The sub-plate 45 is configured integrally with the base plate 42 by connecting the outer frame portion 46 c to the hinge portion 44.

  Here, a mechanism for switching the contents from the connecting member 4 between the direct discharge and the fog state and ejecting the contents will be described.

  FIG. 3 shows the configuration of the first ejection hole 6a, the spin groove 6b formed on the outer side in the radial direction, and the inlet 6c for guiding the contents from the connecting member 4 to the first ejection hole 6a. As shown in the drawing, the spin groove 6b forms a flow path that turns in the radial direction toward the inner side in the radial direction, and guides the contents entering from the inflow port 6c to the first ejection hole 6a while applying spin. As shown in FIG. 1, the spin groove 6b is disposed adjacent to the upstream side of the first ejection hole 6a. As shown in FIG. 4C and the like, the inflow port 6c is a notch formed on the inner peripheral surface of the peripheral wall extending rearward from the first ejection hole 6a and surrounding the spin element 4a from the radially outer side. is there. As shown in FIG. 3, the inflow port 6c is formed at the same circumferential position as the spin groove 6b. The first ejection holes 6a, the spin grooves 6b, and the inflow ports 6c shown in FIG. 3 are partially enlarged views when the first nozzle 6 is viewed from the upstream side.

  On the other hand, on the connecting member 4 side, as shown in FIG. 1, a spin element 4a is provided so as to face the spin groove 6b. 4A and 4B are (a) a front view and (b) a right side view of the spin element 4a when the ejection pattern is set to direct discharge. FIG. 4C is an enlarged cross-sectional view of the first nozzle 6 portion when the ejection pattern is set to direct discharge. In the liquid ejector 100 according to the present embodiment, the connecting member 4 is fixed to the ejector body 1, and the first nozzle 6 rotates around the central axis C with respect to the connecting member 4, so that the spin groove 6 b The relative position with respect to the spin element 4a changes, and the ejection pattern of the contents changes. However, in FIG. 4 to FIG. 6, for facilitating understanding, the first nozzle 6 side is illustrated from the same direction, and the connection member 4 is rotated around the central axis C with respect to the first nozzle 6. explain. That is, in FIGS. 4 to 6, the spin groove 6b of the first nozzle 6 is illustrated with reference to the first nozzle 6 so that the spin groove 6b is oriented in the vertical direction (see FIG. 3). The image is rotated around C.

  When the user adjusts the rotation of the first nozzle 6 around the central axis C and sets the ejection pattern to direct discharge, the spin element 4a has the first notch 4a1 as shown in FIG. Oriented in the same direction as the inlet 6c and the spin groove 6b. As shown in FIG. 4B, the first notch 4a1 has a flow path so that the contents toward the first ejection hole 6a are gradually guided from the radially outer side toward the central axis C toward the radially inner side. Is formed. When the user manually operates the operation lever 3 in FIG. 1 and pulls it 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 and the pump 2 The liquid pressure inside the pump 2 is increased, and the liquid inside the pump 2 is sent out from the hole 34d to the internal passage P via the second check valve 33c. The contents pumped from the internal passage P to the connecting member 4 are gradually guided radially inward toward the first ejection holes 6a as shown by arrows in FIG. An object reaches the first ejection hole 6a from the inlet 6c without passing through the spin groove 6b. Therefore, the contents that have passed through the first ejection holes 6a are directly discharged without turning.

  Next, the case where the ejection pattern is set to a fog state by adjusting the rotation of the first nozzle 6 will be described with reference to FIG. When the ejection pattern is set to a fog state, the spin element 4a has the second cutout portion 4a2 oriented in the same direction as the inlet 6c and the spin groove 6b, as shown in FIG. As shown in FIG. 5 (b), the second notch 4a2 flows so that the content entering from the inlet 6c and going to the first ejection hole 6a flows on the outer peripheral side of the spin element 4a in parallel to the central axis C. A road is formed. Then, the contents guided along the second notch 4a2 reach the first ejection hole 6a while turning when passing through the spin groove 6b from the outer peripheral end toward the center (FIG. 3 and FIG. 3). 5 (c)). Then, the contents accompanied by the swirling are ejected in a mist form from the first ejection holes 6a.

  Next, the case where the ejection is set to the stop state by adjusting the rotation of the first nozzle 6 will be described with reference to FIG. As shown in FIG. 6A, when the ejection is set to the stop state, the spin element 4a is not oriented in the same direction as the spin groove 6b in any of the cutout portions 4a1 and 4a2. Accordingly, the content pumped through the internal passage P cannot reach the first ejection hole 6a through the notches 4a1 and 4a2, and is blocked by the spin element 4a, so that the content is not ejected.

  Next, the case where the ejection pattern is set to the shower state will be described with reference to FIG. In order to bring the spray pattern into the shower state, the second nozzle 40 is rotated around the axis 6s, and the peripheral wall 42a formed on the base plate 42 is fitted to the fitting tube of the first nozzle 6 as shown in FIGS. The second nozzle 40 is fixed so as not to rotate with respect to the first nozzle 6 (operating position) by being fitted to the inner peripheral surface of the portion 6g. As a result, the content pumped to the connecting member 4 from the internal passage P in FIG. 1 passes through the first ejection hole 6a, and further passes through the groove 46a (second ejection hole) and is ejected in the shower state. The

  In the example shown in FIG. 7, the case where the relative position between the spin groove 6b and the spin element 4a is the same as the “direct discharge” shown in FIG. 4 has been described, but the present invention is not limited to this mode. In order to set the ejection pattern to the shower state, the second nozzle 40 only needs to be in the “operating position”, and the relative position between the spin groove 6b and the spin element 4a is the same as the “mist state” shown in FIG. You may comprise so that it may carry out.

  The second nozzle 40 may be formed with a plurality of second ejection holes 46f around the central axis C on the same circumference as shown in FIG. 8 instead of the plurality of grooves 46a shown in FIG. . The second ejection hole 46f is a circular hole, but may have various hole shapes depending on the application.
