A suction pipe 13 is fitted to the lower end of the cylinder 10. A suction valve (not shown) is provided in the lower part of the cylinder 10 as a general form of this type of pump.
[0015]
The vertical movement member 5 is for ejecting the liquid in the container body A from the jet outlet at the tip through the cylinder 10 and passes through the upper end of the mounting cylinder 7 so that it can be moved up and down in the upward biased state. The tube 14 protrudes and a jet port 15 is opened at the tip. In the illustrated example, the upper part of the dispensing cylinder 14 is refracted forward, a nozzle 16 is fitted at the tip, and a jet port 15 is opened at the tip of the nozzle 16. A piston (not shown) protrudes from the outer periphery of the lower end of the dispensing cylinder 14 and is slidably fitted into the cylinder. The nozzle has a general discharge valve. Accordingly, when the vertical movement member 5 is pushed down, the pressurized liquid in the cylinder opens the discharge valve and is ejected from the outlet, and when the vertical movement member 5 is raised, the suction valve is opened and the liquid in the container is piped 13. It is configured to suck up through.
[0016]
The trigger member 6 is for pushing down the vertical movement member 5 against the upward urging force by retracting the equipped trigger and operating the pump, and the rear portion is linked to the support plate portion 8 so as to be rotatable. At the same time, the intermediate part in the front-rear direction is linked to the vertically moving member 5 so that the intermediate part can be pushed down, and the trigger 17 at the front part is hung forward from the mounting cylinder 7.
[0017]
In the illustrated example, a pair of side plates 19 positioned on both sides of the vertical movement member 5 are extended forward from the rear end shaft attachment plate 18 pivotally attached between the support plate portions 8, and the front side of each side plate is provided. A trigger 17 is vertically suspended from the lower surface of each part, and each side plate 19 is linked to the vertical movement member 5 so as to be able to be pushed down. Rotating shafts 20 are respectively provided on both sides of the shaft attaching plate 18 so as to be rotatably fitted in the bearing holes 9 of the support plate portion 8.

As an expression form of the display unit 24, characters, pictures, designs, symbols, and the like can be used, and these may be used in combination.
[0020]
As the display unit 24, for example, one that specifies each pull-in of the trigger 17 or expresses an appropriate ejection amount of the stored liquid, or one that specifies the necessary multiple pull-in of the trigger 17 can be adopted. More specifically, a mark such as an arrow is provided as an index on the axis attachment plate or the support plate portion, a number as a part of the display portion 24 is provided at the mark facing position, and the trigger 17 is retracted once. It is configured so that the next number moves to the mark facing position when the display plate 23 is rotated, or the amount that the stored liquid is effectively used is the amount of ejection when the trigger 17 is pulled in a predetermined number of times. In this case, for example, a mark such as an arrow can be similarly applied, and a character or a number as the display unit 24 can be applied to the outer edge of the display plate 23 at the position where the trigger 17 is pulled three times.
[0021]
The rotation adjusting mechanism 26 is provided at a predetermined position facing the plurality of first protrusions 27 arranged annularly on one side surface of the display plate 23 and one side surface of the display plate, and when the trigger member 6 is rotated in the forward direction. The display plate 23 is rotated by engaging with the first protrusion 27, and the first protrusion 27 a adjacent to the first protrusion 27 is moved over and engaged when rotating in the reverse direction after a predetermined angle rotation. The second protrusion 28, the plurality of third protrusions 29 arranged annularly on the other side surface of the display plate 23, and the opposite surface of the other side surface of the display plate are provided at predetermined positions, and the third is provided when the trigger member is rotated in the forward direction. From the contacted state of the protrusion 29, the adjacent third protrusion 29a is moved over and engaged, and the adjacent third protrusion 29a is engaged when rotating in the reverse direction after a predetermined angle of rotation to rotate the display plate 23. It is composed of a fourth protrusion 30 that prevents movement.
In the illustrated example, as shown in FIG. 7, the first protrusions 27 are provided at 12 positions at equal intervals around the rotation shaft 20 on the inner surface of the display plate 23, and the second protrusions 28 are the first protrusions 27. One side of one protrusion 27 is abutted and locked.
[0023]
As shown in FIG. 8, each first protrusion 27 is inclined downward from the one side edge toward the other side edge in the counterclockwise direction, and the cross section in the circumferential direction forms a right triangle. Further, the second protrusion is inclined downward from the one side edge to the other side edge in the direction opposite to the first protrusion 27. Therefore, the trigger 17 is pulled in and the second protrusion 28 is rotated counterclockwise. Then, the first protrusions 27 with which the vertical surfaces having large protrusions are engaged with each other also rotate counterclockwise by a predetermined angle.
[0024]
Next, when the trigger 17 returns, the second protrusion 28 rotates clockwise, and the first protrusion 27a adjacent to the first protrusion 27a is opposed to the first protrusion 27a adjacent to the first protrusion 27a. The second protrusions 28 are forcibly overcome and the vertical surfaces are engaged with each other.
[0025]
As shown in FIG. 9, the third projections 29 are provided on the outer surface of the display plate 23 at 12 positions at equal intervals around the rotation shaft 20, and the fourth projections 30 are the same as the third projections 29. One side is abuttingly locked on one side.
[0026]
As shown in FIG. 10, each of the third protrusions 29 is inclined downward in the counterclockwise direction from the one side edge toward the other side edge, and the cross section in the circumferential direction forms a right triangle. Further, the fourth protrusion 30 is inclined downward from the one side edge to the other side edge in the opposite direction to the third protrusion 29. Therefore, the third protrusion 29 is rotated counterclockwise by pulling the trigger 17. As a result, the fourth protrusion 30 and the fourth protrusion 30 that are in contact with each other on the vertical surface and the adjacent third protrusion 29 face each other, so that the adjacent third protrusion 29a forces the fourth protrusion 30 The vertical surfaces abut against each other.
[0027]
Next, when the trigger 17 returns, the adjacent third protrusions 29a are prevented from rotating because the fourth protrusions 30 and the fourth protrusions 30 are in contact with each other in the vertical plane.
[0028]
In this way, the display plate 23 is rotated by a predetermined angle by a single pull-in of the trigger 17, and the display unit 24 is rotated along with the rotation to display a predetermined message at a predetermined position. In the illustrated example, one each of the second protrusions 28 and the fourth protrusions 30 are provided. However, the present invention is not limited to this, and a plurality of them may be provided under the same conditions.
[0029]
【The invention's effect】
As described above, the trigger type liquid ejector of the present invention rotates by a predetermined angle as the trigger 17 is retracted, does not rotate when the trigger 17 is returned, and transmits a required message through the display unit 24. Since 23 is provided, it is possible to easily transmit a message related to the ejection amount due to the retraction of the trigger 17.
[0030]
Further, the display plate 23 is rotatably mounted by fitting a through hole 25 in the center portion to the rotation shaft 20 at the pivotal attachment portion of the support plate portion 8 and the trigger member 6, and is rotated on both sides thereof. Since the rotation adjusting mechanism 26 for controlling the movement is provided, the display plate 23 does not get in the way and the liquid can be easily ejected.
[0031]
Further, in the second means, since the rotation adjusting mechanism 26 is constituted by the first to fourth protrusions on both sides of the display plate 23, it has an advantage that it can be formed compactly.
[0032]
Further, since the third means includes the display unit 24 that expresses an appropriate ejection amount of the storage liquid, it has an advantage that the storage liquid can be effectively ejected without waste.
