It flows from the check valve 96 through the three-way pipe 94 toward the liquid storage part 98. Liquid flow in the opposite direction is blocked by check valve 96.

The three-way pipe 94 has three openings. An adapter 93 is connected to one of the three openings. A check valve 96 and a syringe 97 are attached to the other two of the three openings, respectively. In the state in which the switching cock 95 is arranged in the illustrated direction, all of the three openings provided in the three-way pipe 94 communicate in both directions.

The plunger 99 and the gasket 99G are inserted into the syringe 97. A liquid storage portion 98 is formed in a space surrounded by the gasket 99G and the inner peripheral wall of the syringe 97. The liquid supplied from the check valve 96 is taken into the tip connection part 91 through the three-way pipe 94. The liquid taken into the tip connection part 91 is supplied to the liquid ejection nozzle 61 through the tube T18 (specifically, it is sucked up by the liquid ejection nozzle 61 by the action of the Venturi effect). The liquid flow in the opposite direction is blocked by the check valve 92.

At the base of the syringe 97, a flange 97T is provided. At the base of the plunger 99, a flange 99T is provided. As described above with reference to FIG. 2, the plunger 99 is fitted into the fixing portion 21 of the side cover 20 (see arrow AR97 in FIG. 2). The flange 97T of the syringe 97 is fitted between the fixed portion 25 and the fixed portion 26 (see arrow AR98 in FIG. 2). The flange 99T of the plunger 99 is fitted into the fitting portion 75C of the connecting member 75 (see arrow AR99 in FIG. 2).

(Operation of the ejection device 1000)
The operation of the ejection device 1000 having the above configuration will be described with reference to FIGS. 15 and 16 are cross-sectional views showing the ejection device 1000 that forms the first state S1. 17 and 18 are cross-sectional views showing the ejection device 1000 that forms the second state S2. 19 and 20 are cross-sectional views showing the ejection device 1000 that forms the third state S3. 21 and 22 are cross-sectional views illustrating the ejection device 1000 that forms the fourth state S4. 23 and 24 are cross-sectional views showing the ejection device 1000 that forms the fifth state S5.

The ejection device 1000 sequentially transitions from the first state S1 to the fifth state S5. 15, 17, 19, 21, and 23 mainly show the operation of the powder 310. 16, 18, 20, 22, and 24 mainly show the operation of the liquid 410.

(First state S1)
Referring to FIGS. 15 and 16, a predetermined external force is applied to pressing portion 76 of movable unit 70 (the state shown in FIGS. 15 and 16). The plate 71 of the movable unit 70 receives a pressing force in the backward direction from the elastic member 65 by the restoring force of the elastic member 65.

In the state where the ejection device 1000 forms the first state S1, the powder storage container 300 is attached to the container attachment portion 30. The powder 310 inside the powder storage container 300 falls through the inside (through hole 33) of the cylindrical portion 32 of the container mounting portion 30 due to the action of gravity (state shown in FIG. 15). Thereafter, the powder 310 reaches the upper surface of the plate 71. Similarly, the liquid storage container 400 is attached to the container attachment portion 40. The liquid 410 inside the liquid storage container 400 flows to the tube T17 and the check valve 96 by the action of gravity.

15 and 16, the through hole 70 </ b> H provided in the plate 71 is located in front of the through hole 33 of the container mounting portion 30. In this state, when the external force applied to the pressing portion 76 is released, the plate 71 of the movable unit 70 receives the restoring force of the elastic member 65 and moves toward the position most retracted with respect to the side covers 10 and 20. It moves (the ejection device 1000 transitions from the first state S1 to the second state S2 described below).

(Second state S2)
Referring to FIGS. 17 and 18, plate 71 receives the pressing force from elastic member 65 and moves backward in the direction of arrow DR10. As the plate 71 moves backward, the connecting member 75 fitted in the notch 71C also moves in the same direction. Along with the connecting member 75, the plunger 99 also moves backward in the direction of the arrow DR11.

In accordance with the backward movement of the plate 71, the through hole 70H provided in the plate 71 also moves backward and approaches the through hole 33 of the container mounting portion 30. When the bulging portion 77 comes into contact with the inner walls of the side covers 10 and 20, the backward movement of the plate 71 stops. At this time, the through hole 70 </ b> H faces the through hole 33 of the container mounting portion 30. The powder 310 that has been stationary on the upper surface of the plate 71 falls toward the inside of the through hole 70H and is supplied to the inside of the through hole 70H (see FIG. 17).

As the plunger 99 moves backward, negative pressure is generated in the liquid storage unit 98. The liquid 410 inside the liquid storage container 400 is sucked (taken in) into the liquid storage part 98 through the container mounting part 40, the tube T17, and the like.

In the second state S2, the first compressed air introduction portion 66L (see FIG. 12) is separated from the valve member 78L (see FIG. 12). No compressed air is supplied to the first compressed air introduction part 66L, the powder storage case 68, and the powder ejection part 63. In the second state S2, the second compressed air introduction portion 66R (see FIG. 12) is also away from the valve member 78R (see FIG. 12). Neither compressed air is supplied to the second compressed air introduction portion 66R and the air ejection nozzle 62.

(Third state S3)
Referring to FIGS. 19 and 20, the plate 71 moves forward in the direction of the arrow DR12 in response to the pressing force applied to the pressing portion 76 by the operator. As the plate 71 moves forward, the through hole 70H provided in the plate 71 also moves forward. The through hole 70 </ b> H approaches the opening 68 </ b> H of the powder container case 68. The powder 310 inside the through hole 70H (shown as the powder 320 in FIG. 19) also approaches the opening 68H of the powder storage case 68.

When the through hole 70H and the opening 68H communicate with each other, the powder 320 falls toward the inside of the powder storage case 68 (the state shown in FIG. 19 is obtained). The powder 310 taken into the through hole 70H in a state where the through hole 70H communicates with the cylindrical portion 32 (through hole 33) of the container mounting portion 30 and the powder storage container 300, the through hole 70H has a powder containing case. In a state communicating with 68, the powder is supplied to the powder storage case 68.

When the plate 71 moves forward, the connecting member 75 moves relative to the plate 71 inside the notch 71C. The absolute position of the connecting member 75 does not change. The absolute position of the plunger 99 does not change.

Even in the third state S3, the first compressed air introduction portion 66L (see FIG. 12) is separated from the valve member 78L (see FIG. 12). No compressed air is supplied to the first compressed air introduction part 66L, the powder storage case 68, and the powder ejection part 63. Also in the third state S3, the second compressed air introduction portion 66R (see FIG. 12) is separated from the valve member 78R (see FIG. 12). Neither compressed air is supplied to the second compressed air introduction portion 66R and the air ejection nozzle 62.

(Fourth state S4)
Referring to FIGS. 21 and 22, plate 71 further moves forward in the direction of arrow DR13 in response to the pressing force applied to the pressing portion 76 by the operator. As the ejection device 1000 transitions from the third state S3 to the fourth state S4, the first compressed air introduction part 66L (see FIG. 13) is inserted into the valve member 78L (the state shown in FIG. 13 is obtained). ). The connection nozzle 72 transitions from the first non-communication state C10 (see FIG. 12) to the first communication state C11 (see FIG. 13).

As described above with reference to FIG. 13, the compressed air supplied to the tube T11 is compressed powder air, and the inlet 81 of the compressed air distribution pipe 80, the discharge section 82 of the compressed air distribution pipe 80, and the tube T12. , Through the connection nozzle 72 and the space 77L (see FIG. 13), is supplied to the first compressed air introduction portion 66L. The compressed air for powder supplied to the first compressed air introduction section 66L is the tube T14, the rear connection pipe 68M, the internal space of the powder storage case 68, the front connection pipe 68N, the tube T15, and the powder ejection section 63. And is ejected to the outside together with the powder 320 (shown as powder 330 in FIG. 21).

The communication between the powder storage case 68 and the powder storage container 300 is blocked by the plate 71 (in other words, the powder storage case 68 does not communicate with the powder storage container 300). The powder 310 in the powder storage container 300 is not continuously supplied from the powder storage container 300 to the powder storage case 68. The powder ejection unit 63 continues to eject the powder 330 until the powder 320 inside the powder storage case 68 is exhausted. That is, the ejection amount of the powder 330 ejected from the powder ejection portion 63 is the amount of the powder 320 taken into the through hole 70H from the powder storage container 300 as the plate 71 moves forward (in the through hole 70H). Volume).

As the plate 71 moves forward, the connecting member 75 is pressed by the end 71D (see FIG. 9) of the notch 71C and moves in the direction of the arrow DR14. The liquid 410 inside the liquid storage unit 98 moves toward the check valve 96 side. Also in the fourth state S4, the second compressed air introduction portion 66R (see FIG. 13) is separated from the valve member 78R (see FIG. 13). Neither compressed air is supplied to the second compressed air introduction portion 66R and the air ejection nozzle 62.

(Fifth state S5)
Referring to FIGS. 23 and 24, plate 71 further moves forward in the direction of arrow DR15 in response to the pressing force applied to the pressing portion 76 by the operator. As the ejection device 1000 transitions from the fourth state S4 to the fifth state S5, the first compressed air introduction part 66L (see FIG. 14) is inserted into the lid member 78M (the state shown in FIG. 14 is obtained). ). The connection nozzle 72 transitions from the first communication state C11 (see FIG. 13) to the first non-communication state C12 (see FIG. 14). The opening of the first compressed air introduction portion 66L is closed by the lid member 78M. The connection nozzle 72 does not communicate with the first compressed air introduction part 66L.

On the other hand, as the plate 71 moves forward, the connecting member 75 and the plunger 99 move in the direction of the arrow DR15. The second compressed air introduction portion 66R is inserted into the valve member 78R (the state shown in FIG. 14 is obtained). The connection nozzle 73 communicates with the second compressed air introduction portion 66R through the space 77R (see FIG. 14). The connection nozzle 73 is switched from the second non-communication state D21 to the second communication state D22.

When the connection nozzle 73 forms the second communication state D22, the compressed air supplied to the tube T11 is used as liquid compressed air, and the inlet 81 of the compressed air distribution pipe 80 and the discharge of the compressed air distribution pipe 80 83, the tube T13, the connection nozzle 73, and the space 77R (see FIG. 14) are supplied to the second compressed air introduction section 66R.

The compressed air for liquid supplied to the second compressed air introduction section 66R is ejected to the outside through the tube T16 and the air ejection nozzle 62. The compressed air for liquid ejected from the air ejection nozzle 62 generates a negative pressure near the tip of the liquid ejection nozzle 61. The compressed air for liquid ejected from the air ejection nozzle 62 causes the liquid 410 taken into the liquid storage section 98 to be ejected from the liquid ejection nozzle 61 using the action of the Venturi effect (in FIG. 23, it is a mist-like shape). It is shown as liquid 420).

The action of the negative pressure due to the Venturi effect is not strong enough to suck the liquid 410 from the liquid storage container 400 into the liquid storage unit 98, so that the liquid 410 is not continuously supplied from the liquid storage container 400 to the liquid storage unit 98. . The liquid ejection nozzle 61 continues to eject (spray) the liquid 420 until the liquid 410 in the liquid storage unit 98 runs out. That is, the ejection amount of the liquid 420 ejected from the liquid ejection nozzle 61 depends on the amount of the liquid 410 taken into the liquid storage unit 98 from the liquid storage container 400 with the backward movement of the plunger 99 interlocked with the plate 71. Can be adjusted.

23 and 24, the state in which all of the liquid 410 inside the liquid container 98 is ejected is substantially equal to the state shown in FIGS. 15 and 16 (first state S1). The plate 71 of the movable unit 70 receives a pressing force in the backward direction from the elastic member 65 by the restoring force of the elastic member 65. In the state shown in FIGS. 23 and 24, when the external force applied to the pressing portion 76 is released, the plate 71 of the movable unit 70 moves toward the position most retracted with respect to the side covers 10 and 20 (spouting). The device 1000 transitions from the fifth state S5 to the second state S2.)

As described above, the ejection device 1000 easily separates the powder 330 and the liquid 420 separately by one pushing operation on the pressing portion 76 of the plate 71 (in other words, by one forward movement of the plate 71). Can be ejected. By repeating the transition from the first state S1 to the fifth state S5, the ejection device 1000 can easily and continuously perform the operation of ejecting the powder 330 and the liquid 420 separately. By using the ejection device 1000, an operator can easily spray powder and liquid separately toward a desired location.

(First modification)
As described above with reference to FIG. 9, in the ejection device 1000, the length of the first compressed air introduction portion 66L is longer than the length of the second compressed air introduction portion 66R, and the interval L2 is larger than the interval L1. . As the plate 71 is operated along the operation direction indicated by the arrow A1 (see FIG. 9), the plate 71 moves forward. The connection nozzle 72 that forms the first non-communication state C10 switches to the first communication state C11, and then the connection nozzle 73 that forms the second non-communication state D20 switches to the second non-communication state D21. .

In other words, in the ejection device 1000, after the powder 330 is ejected, the liquid 420 is ejected. The powder 330 and the liquid 420 may be ejected simultaneously as necessary. In order to realize this configuration, the lengths of the first compressed air introduction portion 66L and the second compressed air introduction portion 66R are made the same, and the value of the interval L1 and the value of the interval L2 in FIG. .

If necessary, the powder 330 may be ejected after the liquid 420 is ejected. In order to realize this configuration, the length of the second compressed air introduction portion 66R is made longer than the first compressed air introduction portion 66L, and the value of the interval L2 is made smaller than the value of the interval L1 in FIG. Good.

(Second modification)

The connecting member 75 is used to be interlocked. The connecting member 75 may be provided as necessary. When the connection member 75 is not provided, the amount of the liquid 410 taken into the liquid storage unit 98 can be freely increased or decreased according to the stroke amount of the plunger 99.

(Third Modification)
The ejection device 1000 includes a powder storage container 300 and a liquid storage container 400, and can eject the powder 330 and the liquid 420 separately in succession. When continuous ejection is unnecessary, the powder storage container 300 and the liquid storage container 400 may be used as necessary. When the powder storage container 300 is not used, a configuration in which the powder 320 is supplied to the powder storage case 68 through the through hole 70H of the plate 71 may be adopted as necessary. When the liquid storage container 400 is not used, the air ejection nozzle 62 is not necessary, and the action of the venturi effect may not be used. In this case, for example, the liquid ejection nozzle 61 communicates directly with the liquid accommodation section 98 in the same manner as the powder 320 in the powder accommodation case 68 is ejected through the powder ejection section 63. It is comprised so that compressed air may be ejected from. The liquid 420 is ejected from the liquid ejection nozzle 61 together with the compressed air ejected from the liquid ejection nozzle 61 in the same manner as the powder 330. Even when these configurations are employed, the ejection device can eject the powder 330 and the liquid 420 separately.
